The characteriza-tion of these motions has been challenging due to energy overlap with waterabsorption and a large vibrational density of states. Recently it has been demon-strated both experimentally and theoretically that vibrational bands can be iso-lated using stationary sample anisotropic terahertz microscopy (SSTAM) fororiented samples, typically realized using protein crystals [1, 2]. In those earlymeasurements, inhibitor binding contrast was demonstrated for high symmetrytetragonal crystals. While high symmetry crystals are ideal for structural deter-minations, they can limit the types of vibrations observable in the ATM mea-surements. Here we show a survey of ATM measurements of triclinic,monoclinic and tetragonal crystals, demonstrating the unique signaturesobservable for the different symmetry groups, leading to a more completedetermination of the vibrational hot spots that may contribute to enzymatic ef-ficiency. The SSATM spectra indicate the presence of conserved vibrationalmodes near 40 cm&lt;sup&gt;-1&lt;/sup&gt; and 55 cm&lt;sup&gt;-1&lt;/sup&gt; for CEWL in triclinic, monoclinic and tetrag-onal lattice systems respectively. For CEWL in the monoclinic lattice system, aprominent band at 20cm1was consistently observed in the SSATM spectrabut not in the triclinic or tetragonal systems. The conserved bands may repre-sent vibrational modes that are unperturbed by crystal contact forces while thedifferences may be related to unique molecular orientation in different crystalsystems.&lt;/p&gt;

The higher activation energy is consistent with the so-called protein dynamical transition associated with beta relaxations at the solvent–protein interface. The lower activation energy is consistent with correlated structural motions. When the structure is removed by denaturing, the lower-activation-energy process is no longer present. Additionally, the lower-activation-energy process is diminished with ligand binding but not for changes in the internal oxidation state. We suggest that the lower-energy activation process is associated with collective structural motions that are no longer accessible with denaturing or binding.&lt;/p&gt;

For example, near-field THz anisotropic absorption successfully isolated protein structural vibrations which are connected to biological function. However, to determine how these vibrations impact function requires high throughput measurements of these complex systems, which is challenged by the need for near field detection, sample environmental control and full polarization variation. Stationary sample anisotropic terahertz spectroscopy (SSATS) and near-field stationary sample anisotropic terahertz microscopy (SSATM) have been proposed using synchronous control of THz and electro optic probe polarizations along an iso-response curve. Here we realize these techniques through robust control and calibration of the THz and NIR polarization states. Both methods rapidly measure the linear dichroism in the far field and near field. Validation measurements using standard birefringent sucrose single crystals found the crystal orientation can be determined by scanning the reference polarization and the synchronous pump–probe polarization settings can be optimized to eliminate artifacts. SSATM is then used to determine spectral reproducibility and dehydration effects for a series of chicken egg white lysozyme samples. Reproducible anisotropic absorbance bands are found at about 30, 44, 55, and 62 cm&lt;sup&gt;–1&lt;/sup&gt;. These bands initially sharpen with slow dehydration, similar to the increase in resolution achieved in X-ray crystallographic protein structure determination. The SSATM technique confirms the reliability of anisotropic absorption characterization of protein intramolecular vibrations and opens an avenue for rapid determination of how these long-range dynamics affect biological function.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><section><style face="normal" font="default" size="100%">658</style></section></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">A.

Combining single-crystal anisotropy measurements with density functional calculations, we assign the phonon frequencies and interrogate how specific phonons behave with melting. While nearly all the low-frequency phonons continuously red-shift with heating and melting, the lowest-energy phonon polarized along the c-axis blue-shifts at the melting temperature, suggesting an initial structural change immediately before melting. We find that the kinetics follow a 3D growth model with large activation energies, consistent with previous differential scanning calorimetry (DSC) measurements. The large activation energies indicate that multiple H-bonds must break collectively for the transition. The results suggest the generality of the kinetics for molecular crystals and that THz TDS with picosecond resolution could be used to measure ultrafast kinetics.&lt;/p&gt;

Measurements of the protein dynamical transition using terahertz time-domain spectroscopy show in all cases an increase in the turn-on temperature in the bleached state. The result is surprising given that there is little change in the protein surface, and thus, the solvent dynamics held responsible for the transition should not change. A spectral analysis of the measurements guided by quasiharmonic calculations of the protein absorbance reveals that indeed the solvent dynamical turn-on temperature is independent of the thermal stability/photostate however the protein dynamical turn-on temperature shifts to higher temperatures. This is the first demonstration of switching the protein dynamical turn-on temperature with protein functional state. The observed shift in protein dynamical turn-on temperature relative to the solvent indicates an increase in the required mobile waters necessary for the protein picosecond motions, that is, these motions are more collective. Melting-point measurements reveal that the photobleached state is more thermally stable, and structural analysis of related RFP’s shows that there is an increase in internal water channels as well as a more uniform atomic root mean squared displacement. These observations are consistent with previous suggestions that water channels form with extended light excitation providing O&lt;sub&gt;2 &lt;/sub&gt;access to the chromophore and subsequent fluorescence loss. We report that these same channels increase internal coupling enhancing thermal stability and collectivity of the picosecond protein motions. The terahertz spectroscopic characterization of the protein and solvent dynamical onsets can be applied generally to measure changes in collectivity of protein motions.&lt;/p&gt;

It is the only known photoactive protein that uses a carotenoid, canthaxanthin, as its chromophore. The structure of OCP consists of two globular domains, connected by an unstructured loop, that forms a hydrophobic pocket for the carotenoid. In low light, canthaxanthin bound OCP is inactive and appears orange. Illumination by strong light results in an active state that interacts with the PBS to induce fluorescence quenching, a red appearance and conformational changes that include a 12Å shift by canthaxanthin into the N-terminal domain. Terahertz (THz) dynamical transition measurements and anisotropic terahertz microscopy are used to measure the intramolecular structural dynamics in the inactive and active states, which can be induced by photoexcitation or chaotropic salts. The measurements indicate that the active state has a decrease in structural flexibility, which may be related to enhanced interactions with the PBS.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Meeting Abstract</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000513023201290</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: KK8YX&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 0&lt;br/&gt;McKinney, Jeffrey A.

We measure the polarization rotation (Re[theta(F)]) and ellipticity (Im[theta(F)]) of transmitted radiation through thin films as the sample is rotated. We observe a twofold rotational symmetry in theta(F), which is associated with linear dichroism (LD) and occurs when electromagnetic radiation polarized along one direction is absorbed more strongly than radiation polarized in the perpendicular direction. Such polarization anisotropies can be generally associated with symmetry breakings. We measure the amplitude of the LD signal and study its temperature, energy, and doping dependence. The LD signal shows a resonant behavior with a peak in the few hundred meV range, which is coincident with the midinfrared optical feature that has been associated with the formation of the pseudogap state. The strongest LD signal is found in underdoped films, although it is also observed in optimally and overdoped samples. The LD signal is consistent with an electronic nematic order which is decoupled from the crystallographic axes as well as novel magnetoelectric effects.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000562627700004</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: NE5GO&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 30&lt;br/&gt;Cited References: &lt;br/&gt;     Acbas G, 2009, PHYS REV LETT, V103, DOI 10.1103/PhysRevLett.103.137201&lt;br/&gt;     Armitage NP, 2014, PHYS REV B, V90, DOI 10.1103/PhysRevB.90.035135&lt;br/&gt;     Arpaia R, 2018, PHY REV MATER, V2, DOI 10.1103/PhysRevMaterials.2.024804&lt;br/&gt;     Basov DN, 2005, REV MOD PHYS, V77, P721, DOI 10.1103/RevModPhys.77.721&lt;br/&gt;     Blumberg G, 1996, PHYS REV B, V53, P11930, DOI 10.1103/PhysRevB.53.R11930&lt;br/&gt;     Cerne J, 2000, PHYS REV LETT, V84, P3418, DOI 10.1103/PhysRevLett.84.3418&lt;br/&gt;     Fauque B, 2006, PHYS REV LETT, V96, DOI 10.1103/PhysRevLett.96.197001&lt;br/&gt;     Fridman I, 2011, PHYS REV B, V84, DOI 10.1103/PhysRevB.84.104522&lt;br/&gt;     George DK, 2012, J OPT SOC AM B, V29, P1406, DOI 10.1364/JOSAB.29.001406&lt;br/&gt;     Halperin B.

In the case of TIM, structural dynamics are known to be essential to function. In particular the stabilization of the binding pocket by a phosphodianion “handle” of the substrate and the closing of catalytic site loops 6 and 7 over the substrate. Loop 6 moves by as much as 7 Angstroms with binding. Recently a mutant survey for human TIM (hsTIM) found kcat can change significantly for a single mutation distant from the catalytic site. Crystallographic measurements find no structural change with the mutation, suggesting a dynamical mechanism for the allosteric effect. Here we use Stationary Sample Anisotropic Terahertz Microscopy (SSATM) to measure the long-range intramolecular vibrations and determine if specific vibrations couple the allosteric and catalytic sites. SSATM isolated protein long-range structural vibrations based on the dominant displacement direction [1-4]. We examine if specific vibrational bands are associate with loop 6 and loop 7 flexibility.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Meeting Abstract</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000513023201285</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: KK8YX&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 4&lt;br/&gt;Cited References: &lt;br/&gt;     Acbas G, 2014, NAT COMMUN, V5, DOI 10.1038/ncomms4076&lt;br/&gt;     Niessen K.A.

Low-frequency structural vibrations are a mechanism of this long-distance connection and are often used computationally to predict correlations, but experimentally identifying the vibrations associated with specific motions has proved challenging. Spectroscopy is an ideal tool to explore these excitations, but measurements have been largely unable to identify important frequency bands. The result is at odds with some previous calculations and raises the question what methods could successfully characterize protein structural vibrations. Here we show the lack of spectral structure arises in part from the variations in protein structure as the protein samples the energy landscape. However, by averaging over the energy landscape as sampled using an aggregate 18.5 mu s of all-atom molecular dynamics simulation of hen egg white lysozyme and normal-mode analyses, we find vibrations with large overlap with functional displacements are surprisingly concentrated in narrow frequency bands. These bands are not apparent in either the ensemble averaged vibrational density of states or isotropic absorption. However, in the case of the ensemble averaged anisotropic absorption, there is persistent spectral structure and overlap between this structure and the functional displacement frequency bands. We systematically lay out heuristics for calculating the spectra robustly, including the need for statistical sampling of the protein and inclusion of adequate water in the spectral calculation. The results show the congested spectrum of these complex molecules obscures important frequency bands associated with function and reveal a method to overcome this congestion by combining structurally sensitive spectroscopy with robust normal mode ensemble analysis.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000608875100076</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: PT8QA&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 47&lt;br/&gt;Cited References: &lt;br/&gt;     Acbas G, 2014, NAT COMMUN, V5, DOI 10.1038/ncomms4076&lt;br/&gt;     Bahar I, 2007, CURR OPIN STRUC BIOL, V17, P633, DOI 10.1016/j.sbi.2007.09.011&lt;br/&gt;     Balog E, 2011, J PHYS CHEM B, V115, P6811, DOI 10.1021/jp108493g&lt;br/&gt;     Castro-Camus E, 2008, CHEM PHYS LETT, V455, P289, DOI 10.1016/j.cplett.2008.02.084&lt;br/&gt;     Cerutti DS, 2008, BIOCHEMISTRY-US, V47, P12065, DOI 10.1021/bi800894u&lt;br/&gt;     Cerutti DS, 2019, WIRES COMPUT MOL SCI, V9, DOI 10.1002/wcms.1402&lt;br/&gt;     CHO M, 1994, J CHEM PHYS, V100, P6672, DOI 10.1063/1.467027&lt;br/&gt;     Choi JH, 2014, J PHYS CHEM B, V118, P12837, DOI 10.1021/jp508547y&lt;br/&gt;     Cote Y, 2017, BIOPHYS J, V112, P2575, DOI 10.1016/j.bpj.2017.05.018&lt;br/&gt;     Dong J, 1999, ACTA CRYSTALLOGR D, V55, P745, DOI 10.1107/S0907444998016047&lt;br/&gt;     ESSMANN U, 1995, J CHEM PHYS, V103, P8577, DOI 10.1063/1.470117&lt;br/&gt;     Falconer RJ, 2012, J INFRARED MILLIM TE, V33, P973, DOI 10.1007/s10762-012-9915-9&lt;br/&gt;     FELLER SE, 1995, J CHEM PHYS, V103, P4613, DOI 10.1063/1.470648&lt;br/&gt;     Gerek ZN, 2011, PLOS COMPUT BIOL, V7, DOI 10.1371/journal.pcbi.1002154&lt;br/&gt;     GO N, 1983, P NATL ACAD SCI-BIOL, V80, P3696, DOI 10.1073/pnas.80.12.3696&lt;br/&gt;     Grossfield A, 2019, LIVING J COMPUT MOL, V1, P5067, DOI DOI 10.33011/LIVEC0MS.1.1.5067&lt;br/&gt;     Grossfield A, 2009, ANN REP COMP CHEM, V5, P23, DOI 10.1016/S1574-1400(09)00502-7&lt;br/&gt;     He YF, 2011, BIOPHYS J, V100, P1058, DOI 10.1016/j.bpj.2010.12.3731&lt;br/&gt;     HORIUCHI T, 1991, PROTEINS, V10, P106, DOI 10.1002/prot.340100204&lt;br/&gt;     Huang J, 2013, J COMPUT CHEM, V34, P2135, DOI 10.1002/jcc.23354&lt;br/&gt;     Katebi AR, 2014, PROTEIN SCI, V23, P213, DOI 10.1002/pro.2407&lt;br/&gt;     Kindt JT, 1997, J CHEM PHYS, V106, P4389, DOI 10.1063/1.473486&lt;br/&gt;     Kroll J, 2007, VIB SPECTROSC, V43, P324, DOI 10.1016/j.vibspec.2006.03.010&lt;br/&gt;     Leioatts N, 2012, J CHEM THEORY COMPUT, V8, P2424, DOI 10.1021/ct3000316&lt;br/&gt;     Lerbret A, 2009, J CHEM PHYS, V131, DOI 10.1063/1.3273218&lt;br/&gt;     Meinhold L, 2007, PHYS REV LETT, V99, DOI 10.1103/PhysRevLett.99.138101&lt;br/&gt;     Miller DW, 1999, J MOL BIOL, V286, P267, DOI 10.1006/jmbi.1998.2445&lt;br/&gt;     Niessen KA, 2019, NAT COMMUN, V10, DOI 10.1038/s41467-019-08926-3&lt;br/&gt;     Niessen KA, 2017, BIOPHYS J, V112, P933, DOI 10.1016/j.bpj.2016.12.049&lt;br/&gt;     Phillips JC, 2005, J COMPUT CHEM, V26, P1781, DOI 10.1002/jcc.20289&lt;br/&gt;     Porter JR, 2019, BIOPHYS J, V116, P818, DOI 10.1016/j.bpj.2018.11.3144&lt;br/&gt;     Romo TD, 2014, J COMPUT CHEM, V35, P2305, DOI 10.1002/jcc.23753&lt;br/&gt;     Romo TD, 2009, IEEE ENG MED BIO, P2332, DOI 10.1109/IEMBS.2009.5335065&lt;br/&gt;     Sassi P, 2013, J CHEM PHYS, V139, DOI 10.1063/1.4838355&lt;br/&gt;     Singh R, 2012, J PHYS CHEM A, V116, P10359, DOI 10.1021/jp307288r&lt;br/&gt;     Stehle CU, 2012, J CHEM PHYS, V136, DOI 10.1063/1.3686886&lt;br/&gt;     STRAUB JE, 1994, J PHYS CHEM-US, V98, P10978, DOI 10.1021/j100093a046&lt;br/&gt;     Tehver R, 2009, J MOL BIOL, V387, P390, DOI 10.1016/j.jmb.2008.12.032&lt;br/&gt;     Thirumuruganandham SP, 2009, J MOL MODEL, V15, P959, DOI 10.1007/s00894-008-0446-1&lt;br/&gt;     Whitmire SE, 2003, BIOPHYS J, V85, P1269, DOI 10.1016/S0006-3495(03)74562-7&lt;br/&gt;     Xie AH, 2000, PHYS REV LETT, V84, P5435, DOI 10.1103/PhysRevLett.84.5435&lt;br/&gt;     Xu D, 1996, J PHYS CHEM-US, V100, P12108, DOI 10.1021/jp960076a&lt;br/&gt;     Yu X, 2005, J CHEM PHYS, V122, DOI 10.1063/1.1830431&lt;br/&gt;     Yu X, 2004, CHEM PHYS LETT, V391, P181, DOI 10.1016/j.cplett.2004.04.100&lt;br/&gt;     Zakaria HA, 2011, APPL SPECTROSC, V65, P260, DOI 10.1366/10-06162&lt;br/&gt;     Zhang HL, 2009, J MOL GRAPH MODEL, V27, P655, DOI 10.1016/j.jmgm.2008.10.005&lt;br/&gt;     Zorba A, 2019, P NATL ACAD SCI USA, V116, P13937, DOI 10.1073/pnas.1906024116&lt;br/&gt;Romo, Tod D.

The OCP switches from resting state to photo protective state with intense blue light illumination. Questions persist as to why OCPR interaction increases with the PBS over that with the OCPO. Here we examine the role of long-range intramolecular vibrations within OCP. Using Stationary Sample Anisotropic Terahertz Microscopy (SSATM) we measure changes in the intramolecular vibrations with photo switching. We report the first observation of switching in the intramolecular vibrations with photoexcitation. Results suggest that there is a stiffening of the molecule in the photo protective state. This increase in structural stability may enhance the interaction with the PBS change in OCP interaction with PBS. In low light, carotenoid bound OCP appears orange (OCP &lt;sup&gt;o&lt;/sup&gt; ) and is inactive. Illumination by strong light converts OCP to the active, red (OCPR) state, which interacts with the PBS. A comparison of anisotropic THz microscopy measurements of dark adapted (OCP &lt;sup&gt;o&lt;/sup&gt; ) and illuminated OCP crystals indicate differences in their vibrational modes that may be important for OCP-PBS interactions.&lt;/p&gt;

A chief obstacle to utilizing this control mechanism has been measurement of specific motions. Recently it was shown that while the vibrational density of states, and isotropic absorption spectra are broad and featureless, collective vibrations can be isolated based on their directionality using aligned samples (realized with protein crystals) and anisotropic THz microscopy [1]. However the assignment of resonant bands to specific structural motions was complicated by the high symmetry of the tetragonal crystals used, and the slow experimental method. To structurally map the vibrations of the chicken egg white lysozyme (CEWL) we measure anisotropic absorption of triclinic crystals using our new technique: ideal polarization varying anisotropic THz microscopy (IPV-ATM). The low symmetry triclinic crystals provide absolute protein orientation, and the near field IPV-ATM rapidly measures broadband terahertz linear dichroism of the microcrystals. All measurements were performed at room temperature under 100% humidity conditions. The unit cell parameters of triclinic lysozyme nitrate crystals, α = 28.5A°, b = 32.7A°, c = 35.1A°, α = 88.2°, β = 108.9°, γ = 111.9°, belonging to the P1 space group, were determined by X-ray diffraction before and after THz measurements. The intramolecular vibrational absorbance of the triclinic crystals has a more complex polarization dependence than the higher symmetry tetragonal crystals, as expected. While the tetragonal crystals have two strong bands at 45cm&lt;sup&gt;−1&lt;/sup&gt; and 55cm&lt;sup&gt;−1&lt;/sup&gt;, the triclinic crystals have a series of narrow bands between 40 and 60cm&lt;sup&gt;−1&lt;/sup&gt; and a prominent band at 30cm&lt;sup&gt;−1&lt;/sup&gt;. We compare the measured spectra to normal mode ensemble averaged calculations to assign the observed resonances, and isolating which collective motions impact the catalytic site.&lt;/div&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Meeting Abstract</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000460779802832</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: HO2XG&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 1&lt;br/&gt;Cited References: &lt;br/&gt;     Niessen KA, 2017, BIOPHYS J, V112, P933, DOI 10.1016/j.bpj.2016.12.049&lt;br/&gt;Deng, Yanting Mckinney, Jeffrey Romo, Tod Grossfield, Alan Markelz, Andrea&lt;br/&gt;63rd Annual Meeting of the Biophysical-Society&lt;br/&gt;Mar 02-06, 2019&lt;br/&gt;Baltimore, MD&lt;br/&gt;Biophys Soc&lt;br/&gt;&lt;br/&gt;8&lt;br/&gt;Cell press&lt;br/&gt;Cambridge&lt;br/&gt;1542-0086&lt;br/&gt;1</style></notes><auth-address><style face="normal" font="default" size="100%">[Deng, Yanting|Mckinney, Jeffrey|Markelz, Andrea] SUNY Buffalo, Phys, Buffalo, NY USA.

For most of the 20th Century, terahertz radiation, then referred to as sub-millimeter wave or far-infrared radiation, was mainly utilized by astronomers and some spectroscopists. Following the development of laser based terahertz time-domain spectroscopy in the 1980s and 1990s the field of THz science and technology expanded rapidly, to the extent that it now touches many areas from fundamental science to &#039;real world&#039; applications. For example THz radiation is being used to optimize materials for new solar cells, and may also be a key technology for the next generation of airport security scanners. While the field was emerging it was possible to keep track of all new developments, however now the field has grown so much that it is increasingly difficult to follow the diverse range of new discoveries and applications that are appearing. At this point in time, when the field of THz science and technology is moving from an emerging to a more established and interdisciplinary field, it is apt to present a roadmap to help identify the breadth and future directions of the field. The aim of this roadmap is to present a snapshot of the present state of THz science and technology in 2017, and provide an opinion on the challenges and opportunities that the future holds. To be able to achieve this aim, we have invited a group of international experts to write 18 sections that cover most of the key areas of THz science and technology. We hope that The 2017 Roadmap on THz science and technology will prove to be a useful resource by providing a wide ranging introduction to the capabilities of THz radiation for those outside or just entering the field as well as providing perspective and breadth for those who are well established. We also feel that this review should serve as a useful guide for government and funding agencies.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Review</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000392153700001</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: EI0HL&lt;br/&gt;Times Cited: 541&lt;br/&gt;Cited Reference Count: 209&lt;br/&gt;Cited References: &lt;br/&gt;     Adam AJL, 2011, J INFRARED MILLIM TE, V32, P976, DOI 10.1007/s10762-011-9809-2&lt;br/&gt;     Ahmed SS, 2012, IEEE MICROW MAG, V13, P26, DOI 10.1109/MMM.2012.2205772&lt;br/&gt;     Alliance N., 2015, CISC VIS NETW IND GL, P1&lt;br/&gt;     [Anonymous], 2013, 178512012 IEEE&lt;br/&gt;     [Anonymous], 2014, IEEE T ELECT DEVICES, V61&lt;br/&gt;     [Anonymous], 2012, 178522016 IEEE&lt;br/&gt;     [Anonymous], 2015, P17852 IEEE&lt;br/&gt;     Appleby R, 2015, P SOC PHOTO-OPT INS, V9462&lt;br/&gt;     Arnone DD, 1999, PROC SPIE, V3828, P209, DOI 10.1117/12.361037&lt;br/&gt;     Ashworth PC, 2009, OPT EXPRESS, V17, P12444, DOI 10.1364/OE.17.012444&lt;br/&gt;     AUSTON DH, 1988, IEEE J QUANTUM ELECT, V24, P184, DOI 10.1109/3.114&lt;br/&gt;     Barbieri S, 2011, NAT PHOTONICS, V5, P306, DOI [10.1038/NPHOTON.2011.49, 10.1038/nphoton.2011.49]&lt;br/&gt;     Barker RJ., 2005, MODERN MICROWAVE MIL&lt;br/&gt;     Basov DN, 2011, REV MOD PHYS, V83, P471, DOI 10.1103/RevModPhys.83.471&lt;br/&gt;     Bauwens M.

In particular, protein vibrations are closely spaced in frequency, resulting in a nearly continuous vibrational density of states. This density of vibrations interferes with the identification of specific absorption lines and their subsequent association with specific functional motions. This challenge is compounded with the absorption being dominated by the solvent and local relaxational motions. A strategy for removing the isotropic relaxational loss and isolating specific vibrations is to use aligned samples and polarization-sensitive measurements. Here, we demonstrate a technique to rapidly attain the anisotropic resonant absorbance using terahertz time domain spectroscopy and a spinning sample. The technique, modulated orientation-sensitive terahertz spectroscopy (MOSTS), has a nonzero signal only for anisotropic samples, as demonstrated by a comparison between a silicon wafer and a wire grid polarizer. For sucrose and oxalic acid molecular crystals, the MOSTS response is in agreement with modeled results for the intermolecular vibrations. Further, we demonstrate that, even in the presence of a large relaxational background, MOSTS isolates underlying vibrational resonances.

However red fluorescent proteins (RFPs) are more susceptible to photobleaching than their shorter wavelength counterparts. In particular RFPs are more susceptible to photobleaching [1]. A possible reason for this is a decrease in the structural stability of the beta barrel. Measurements of structural stability include atomic root mean squared displacement &amp;lt;x(2)&amp;gt; measured by the X-ray B-factor and neutron quasi elastic scattering. To date, X-ray measurements of RFP&#039;s do not indicate a structural stability change and systematic scattering studies have not been performed. Using THz dielectric response we examine if the picosecond structural flexibility decreases with increasing FP stability.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:000378889200449</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: BF0IL&lt;br/&gt;Times Cited: 0&lt;br/&gt;Cited Reference Count: 7&lt;br/&gt;Cited References: &lt;br/&gt;     Dean KM, 2011, BIOPHYS J, V101, P961, DOI 10.1016/j.bpj.2011.06.055&lt;br/&gt;     He YF, 2011, BIOPHYS J, V100, P1058, DOI 10.1016/j.bpj.2010.12.3731&lt;br/&gt;     Helms V, 2007, CHEMPHYSCHEM, V8, P23, DOI 10.1002/cphc.200600298&lt;br/&gt;     Leu BM, 2008, BIOPHYS J, V95, P5874, DOI 10.1529/biophysj.108.138198&lt;br/&gt;     Markelz AG, 2007, CHEM PHYS LETT, V442, P413, DOI 10.1016/j.cplett.2007.05.080&lt;br/&gt;     Nagy A, 2004, THERMOCHIM ACTA, V410, P161, DOI 10.1016/S0040-6031(03)00397-6&lt;br/&gt;     Zaccai G, 2000, SCIENCE, V288, P1604, DOI 10.1126/science.288.5471.1604&lt;br/&gt;Xu, Mengyang George, D.

At low frequencies, transport is essentially thickness independent showing the dominant contribution of the surface electrons. Despite their extended exposure to ambient conditions, these surfaces exhibit robust properties including narrow, almost thickness-independent Drude peaks, and an unprecedentedly large polarization rotation of linearly polarized light reflected in an applied magnetic field. This Kerr rotation can be as large as 65 degrees and can be explained by a cyclotron resonance effect of the surface states.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000300576000025</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: 896NY&lt;br/&gt;Times Cited: 164&lt;br/&gt;Cited Reference Count: 35&lt;br/&gt;Cited References: &lt;br/&gt;     Akhmerov AR, 2009, PHYS REV LETT, V102, DOI 10.1103/PhysRevLett.102.216404&lt;br/&gt;     Alpichshev Z, 2010, PHYS REV LETT, V104, DOI 10.1103/PhysRevLett.104.016401&lt;br/&gt;     Analytis JG, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.205407&lt;br/&gt;     Bansal N., ARXIV11045709&lt;br/&gt;     Benia HM, 2011, PHYS REV LETT, V107, DOI 10.1103/PhysRevLett.107.177602&lt;br/&gt;     Bianchi M, 2010, NAT COMMUN, V1, DOI 10.1038/ncomms1131&lt;br/&gt;     Butch NP, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.241301&lt;br/&gt;     Chen J, 2011, PHYS REV B, V83, DOI 10.1103/PhysRevB.83.241304&lt;br/&gt;     Chen YL, 2009, SCIENCE, V325, P178, DOI 10.1126/science.1173034&lt;br/&gt;     Essin AM, 2009, PHYS REV LETT, V102, DOI 10.1103/PhysRevLett.102.146805&lt;br/&gt;     Eto K, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.195309&lt;br/&gt;     Fu L, 2007, PHYS REV B, V76, DOI 10.1103/PhysRevB.76.045302&lt;br/&gt;     Fu L, 2008, PHYS REV LETT, V100, DOI 10.1103/PhysRevLett.100.096407&lt;br/&gt;     Hsieh D, 2008, NATURE, V452, P970, DOI 10.1038/nature06843&lt;br/&gt;     Hsieh D, 2009, NATURE, V460, P1101, DOI 10.1038/nature08234&lt;br/&gt;     Jenkins GS, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.125120&lt;br/&gt;     King PDC, 2011, PHYS REV LETT, V107, DOI 10.1103/PhysRevLett.107.096802&lt;br/&gt;     LaForge AD, 2010, PHYS REV B, V81, DOI 10.1103/PhysRevB.81.125120&lt;br/&gt;     Lan YP, 2011, PHYS REV B, V83, DOI 10.1103/PhysRevB.83.205109&lt;br/&gt;     Maciejko J, 2010, PHYS REV LETT, V105, DOI 10.1103/PhysRevLett.105.166803&lt;br/&gt;     Moore JE, 2007, PHYS REV B, V75, DOI 10.1103/PhysRevB.75.121306&lt;br/&gt;     Qi XL, 2008, PHYS REV B, V78, DOI 10.1103/PhysRevB.78.195424&lt;br/&gt;     Qu DX, 2010, SCIENCE, V329, P821, DOI 10.1126/science.1189792&lt;br/&gt;     Roushan P, 2009, NATURE, V460, P1106, DOI 10.1038/nature08308&lt;br/&gt;     Roy R, 2009, PHYS REV B, V79, DOI 10.1103/PhysRevB.79.195322&lt;br/&gt;     Steinberg H, 2011, PHYS REV B, V84, DOI 10.1103/PhysRevB.84.233101&lt;br/&gt;     Sushkov AB, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.125110&lt;br/&gt;     THOULESS DJ, 1982, PHYS REV LETT, V49, P405, DOI 10.1103/PhysRevLett.49.405&lt;br/&gt;     Tkachov G, 2011, PHYS REV B, V84, DOI 10.1103/PhysRevB.84.035405&lt;br/&gt;     Tse WK, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.161104&lt;br/&gt;     Tse WK, 2010, PHYS REV LETT, V105, DOI 10.1103/PhysRevLett.105.057401&lt;br/&gt;     VONKLITZING K, 1980, PHYS REV LETT, V45, P494, DOI 10.1103/physrevlett.45.494&lt;br/&gt;     Xia Y, 2009, NAT PHYS, V5, P398, DOI 10.1038/NPHYS1274&lt;br/&gt;     Xiong J., PHYSICA A E IN PRESS&lt;br/&gt;     Zhang XA, 2010, PHYS REV B, V82, DOI 10.1103/PhysRevB.82.245107&lt;br/&gt;Aguilar, R.

From this work, we found that the nature of the vibrational motions activated by terahertz radiation is surprisingly similar between these two structurally similar proteins. Specifically, at the lowest frequencies probed, the cytoplasmic loop regions of the proteins are highly active; and at the higher terahertz frequencies studied, the extracellular loop regions of the protein systems become vibrationally activated. In the case of bacteriorhodopsin, the calculated terahertz spectra are compared with the experimental terahertz signature. This work illustrates the importance of terahertz spectroscopy to identify vibrational degrees of freedom which correlate to known conformational changes in these proteins.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000254420100030</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: 280IP&lt;br/&gt;Times Cited: 50&lt;br/&gt;Cited Reference Count: 72&lt;br/&gt;Cited References: &lt;br/&gt;     Abdulaev NG, 1998, P NATL ACAD SCI USA, V95, P12854, DOI 10.1073/pnas.95.22.12854&lt;br/&gt;     Alexandrov V, 2005, PROTEIN SCI, V14, P633, DOI 10.1110/ps.04882105&lt;br/&gt;     Alexiev U, 2003, J MOL BIOL, V328, P705, DOI 10.1016/S0022-2836(03)00326-7&lt;br/&gt;     Altenbach C, 2001, BIOCHEMISTRY-US, V40, P15493, DOI 10.1021/bi011545o&lt;br/&gt;     AMADEI A, 1993, PROTEINS, V17, P412, DOI 10.1002/prot.340170408&lt;br/&gt;     Balog E, 2004, PHYS REV LETT, V93, DOI 10.1103/PhysRevLett.93.028103&lt;br/&gt;     Beck M, 1998, BIOCHEMISTRY-US, V37, P7630, DOI 10.1021/bi9801560&lt;br/&gt;     Bizzarri AR, 2001, EUR BIOPHYS J BIOPHY, V30, P443, DOI 10.1007/s002490100167&lt;br/&gt;     BROOKS B, 1983, P NATL ACAD SCI-BIOL, V80, P6571, DOI 10.1073/pnas.80.21.6571&lt;br/&gt;     BROOKS BR, 1995, J COMPUT CHEM, V16, P1522, DOI 10.1002/jcc.540161209&lt;br/&gt;     Bu ZM, 2000, J MOL BIOL, V301, P525, DOI 10.1006/jmbi.2000.3978&lt;br/&gt;     Chen JY, 2005, PHYS REV E, V72, DOI 10.1103/PhysRevE.72.040901&lt;br/&gt;     Chen Q, 2001, J OPT SOC AM B, V18, P823, DOI 10.1364/JOSAB.18.000823&lt;br/&gt;     Chung HS, 2005, P NATL ACAD SCI USA, V102, P612, DOI 10.1073/pnas.0408646102&lt;br/&gt;     Crozier PS, 2003, J MOL BIOL, V333, P493, DOI 10.1016/j.jmb.2003.08.045&lt;br/&gt;     Farrens DL, 1996, SCIENCE, V274, P768, DOI 10.1126/science.274.5288.768&lt;br/&gt;     Filippovich S.

The results are compared to calculated spectra generated via normal mode analyses using CHARMM. We find that the FIR absorbance is slowly increasing with frequency and without strong narrow features over the range of 2-60 cm(-1) and up to a resolution of 0.17 cm(-1). The broad absorption shifts in frequency with decreasing temperature as expected with a strongly anharmonic potential and in agreement with neutron inelastic scattering results. Decreasing hydration shifts the absorption to higher frequencies, possibly resulting from decreased coupling mediated by the interior water molecules. Ground-state FIR absorbances have nearly identical frequency dependence, with the mutant having less optical density than the WT. In the M state, the FIR absorbance of the WT increases whereas there is no change for D96N. These results represent the first measurement of FIR absorbance change as a function of conformational state.&lt;/p&gt;</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><accession-num><style face="normal" font="default" size="100%">WOS:000184428300052</style></accession-num><notes><style face="normal" font="default" size="100%">ISI Document Delivery No.: 705ZZ&lt;br/&gt;Times Cited: 117&lt;br/&gt;Cited Reference Count: 55&lt;br/&gt;Cited References: &lt;br/&gt;     AUSTIN RH, 1975, BIOCHEMISTRY-US, V14, P5355, DOI 10.1021/bi00695a021&lt;br/&gt;     Birge RR, 1996, J PHYS CHEM-US, V100, P9990, DOI 10.1021/jp953669e&lt;br/&gt;     BOUSCHE O, 1992, PHOTOCHEM PHOTOBIOL, V56, P1085, DOI 10.1111/j.1751-1097.1992.tb09732.x&lt;br/&gt;     BROOKS BR, 1983, J COMPUT CHEM, V4, P187, DOI 10.1002/jcc.540040211&lt;br/&gt;     BROOKS BR, 1995, J COMPUT CHEM, V16, P1522, DOI 10.1002/jcc.540161209&lt;br/&gt;     Brooks CL, 1988, PROTEINS THEORETICAL&lt;br/&gt;     Brucherseifer M, 2000, APPL PHYS LETT, V77, P4049, DOI 10.1063/1.1332415&lt;br/&gt;     Chen Q, 2001, J OPT SOC AM B, V18, P823, DOI 10.1364/JOSAB.18.000823&lt;br/&gt;     DENCHER NA, 1989, P NATL ACAD SCI USA, V86, P7876, DOI 10.1073/pnas.86.20.7876&lt;br/&gt;     Der A, 2001, BIOCHEMISTRY-MOSCOW+, V66, P1234, DOI 10.1023/A:1013179101782&lt;br/&gt;     Diehl M, 1997, BIOPHYS J, V73, P2726, DOI 10.1016/S0006-3495(97)78301-2&lt;br/&gt;     DOSTER W, 1989, NATURE, V337, P754, DOI 10.1038/337754a0&lt;br/&gt;     FERRAND M, 1993, P NATL ACAD SCI USA, V90, P9668, DOI 10.1073/pnas.90.20.9668&lt;br/&gt;     GENZEL L, 1984, SPECTROSCOPY BIOL MO, P609&lt;br/&gt;     GRISCHKOWSKY D, 1991, OSA PROC, V9, P9&lt;br/&gt;     Guilbert C, 1996, CHEM PHYS, V204, P327, DOI 10.1016/0301-0104(95)00293-6&lt;br/&gt;     Han PY, 2000, OPT LETT, V25, P242, DOI 10.1364/OL.25.000242&lt;br/&gt;     Hinsen K, 1998, PROTEINS, V33, P417, DOI 10.1002/(SICI)1097-0134(19981115)33:3&lt;417::AID-PROT10&gt;3.0.CO;2-8&lt;br/&gt;     JANEZIC D, 1995, J COMPUT CHEM, V16, P1543, DOI 10.1002/jcc.540161210&lt;br/&gt;     Kusnetzow A, 1999, BIOPHYS J, V76, P2370, DOI 10.1016/S0006-3495(99)77394-7&lt;br/&gt;     Lanyi JK, 1999, INT REV CYTOL, V187, P161, DOI 10.1016/S0074-7696(08)62418-3&lt;br/&gt;     Lanyi JK, 2001, TRENDS BIOTECHNOL, V19, P140, DOI 10.1016/S0167-7799(01)01576-1&lt;br/&gt;     LINDSAY SM, 1988, BIOPOLYMERS, V27, P1015, DOI 10.1002/bip.360270610&lt;br/&gt;     Lisy V, 1997, J BIOMOL STRUCT DYN, V14, P517, DOI 10.1080/07391102.1997.10508150&lt;br/&gt;     LONGBOTTOM C, 2002, POTENTIAL USES TERAH&lt;br/&gt;     Luecke H, 1999, SCIENCE, V286, P255, DOI 10.1126/science.286.5438.255&lt;br/&gt;     Luecke H, 1999, J MOL BIOL, V291, P899, DOI 10.1006/jmbi.1999.3027&lt;br/&gt;     MacKerell AD, 1998, J PHYS CHEM B, V102, P3586, DOI 10.1021/jp973084f&lt;br/&gt;     Markelz AG, 2000, CHEM PHYS LETT, V320, P42, DOI 10.1016/S0009-2614(00)00227-X&lt;br/&gt;     MCINTOSH AR, 1991, BIOPHYS J, V60, P1, DOI 10.1016/S0006-3495(91)82025-2&lt;br/&gt;     MOUAWAD L, 1993, BIOPOLYMERS, V33, P599, DOI 10.1002/bip.360330409&lt;br/&gt;     Mouawad L, 1996, J MOL BIOL, V258, P393, DOI 10.1006/jmbi.1996.0257&lt;br/&gt;     Nagel M, 2002, APPL PHYS LETT, V80, P154, DOI 10.1063/1.1428619&lt;br/&gt;     Oesterhelt D, 1974, Methods Enzymol, V31, P667&lt;br/&gt;     Palmo K, 1998, J COMPUT CHEM, V19, P754, DOI 10.1002/(SICI)1096-987X(199805)19:7&lt;754::AID-JCC6&gt;3.0.CO;2-P&lt;br/&gt;     PERAHIA D, 1995, COMPUT CHEM, V19, P241, DOI 10.1016/0097-8485(95)00011-G&lt;br/&gt;     Person W.B., 1982, VIBRATIONAL INTENSIT&lt;br/&gt;     Polavarapu P.

Our results predict an oscillatory dependence of the efficiencies for third-harmonic generation and four-wave mixing on the subband occupation of quantum wells, and for narrow wells with high charge densities predict an enhancement over the bulk susceptibility. We also make a simple estimate of the fields required to saturate this nonparabolicity contribution to chi((3)). We discuss these results in light of recent experiments on third-harmonic generation from narrow-gap quantum wells at frequencies of similar to 1 THz, and show that nonparabolicity may not be the only nonlinearity contributing to the large chi((3)) observed.

We find that the energy distribution can be characterized by an effective electron temperature, T-e(&amp;gt;T-L), that agrees well with values estimated from the THz-illuminated, dc conductivity. This agreement indicates that under strong THz drive, LO phonon scattering dominates both energy and momentum relaxation; that the carrier distribution maintains a heated, thermal form; and that phonon drift effects are negligible.

The theme is the interplay of quantum mechanics, strong periodic driving, the electron-electron interaction and dissipation. We discuss harmonic generation from an asymmetric double quantum well in which the effects of dynamic screening are important. Measurements and theory are found to be in good agreement. We also discuss intensity-dependent absorption in a 400 Angstrom square quantum well. A new nonlinear quantum effect occurs, in which the frequency at which electromagnetic radiation is absorbed shifts to the red with increasing intensity. The preliminary experimental results are in agreement with a theory by Zaluzny, in which the source of the nonlinearity is the self-consistent potential in the Hartree approximation for the electron dynamics.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1995RA41200018</style></accession-num><notes><style face="normal" font="default" size="100%">Sherwin, Mark S/Q-4762-2017&lt;br/&gt;Sherwin, Mark S/0000-0002-3869-1893; Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;14th Annual International Conference of the Center-for-Nonlinear-Studies - Quantum Complexity in Mesoscopic Systems&lt;br/&gt;May 16-20, 1994&lt;br/&gt;Los alamos, nm&lt;br/&gt;Ctr nonlinear studies&lt;br/&gt;34</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Cerne, J.</style></author><author><style face="normal" font="default" size="100%">Markelz, A.

We analyse the dependence of sigma(DC) on E(omega) assuming that electron-optical phonon scattering dominates energy relaxation, that the absorbed power has a Drude form and that the electron distribution is thermal. This simple analysis is self-consistent: Arrhenius plots of the estimated energy loss rate have a slope near -homega(LO)BAR/k(B) for all frequencies, as expected for energy loss by optical phonon emission. We find that the effective energy relaxation time tau(epsilon) varies with the frequency of the applied field, from tau(epsilon) approximately 4 ps at 0.34 THz to tau(epsilon) approximately 0.3 ps at 3.45 THz.

We find that these wells are strongly nonlinear at far-infrared frequencies: odd harmonics ninth order have been observed at high incident intensities, and the peak value of chi(3) reaches approximately 1 esu. This is several orders of magnitude larger than previously reported values for chi(3) in bulk n-GaAs (10(-4) esu)[1] and in polyacetylene (10(-7) esu)[2]. The large magnitude of chi(3) is attributed to the high carrier density in the InAs wells, and to the strong non-parabolicity of the conduction band in InAs. However, the free-carrier chi(3) for bulk InAs predicts a density-dependence different from that observed, and the measured decrease in chi(3) with increasing intensity indicates non-perturbative response. We find that the anisotropy of chi(3) displays the expected 4-fold symmetry.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NE79600163</style></accession-num><notes><style face="normal" font="default" size="100%">Sherwin, Mark S/Q-4762-2017&lt;br/&gt;Sherwin, Mark S/0000-0002-3869-1893; Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;6th International Conference on Modulated Semiconductor Structures&lt;br/&gt;Aug 23-27, 1993&lt;br/&gt;Garmisch partenkir, germany&lt;br/&gt;Tech univ munchen, walter schottky inst&lt;br/&gt;9</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Allen, S.

They have the most impact on terahertz science and technology that require a tunable, high power source to explore non-linear dynamics or that sacrifice incident power to recover the linear response of systems with very small cross-section. We describe three experiments that demonstrate the utility of these lasers in experiments on the terahertz dynamics of semiconductor nanostructures: (i) terahertz dynamics of resonant tunneling diodes, (ii) saturation spectroscopy of quantum wells and (iii) photon-assisted tunneling in superlattices.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NR36100065</style></accession-num><notes><style face="normal" font="default" size="100%">Sherwin, Mark S/Q-4762-2017; Guimaraes, Paulo Sergio Soares/B-6918-2012&lt;br/&gt;Sherwin, Mark S/0000-0002-3869-1893; Guimaraes, Paulo Sergio Soares/0000-0002-0113-2641; Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;1993 International Conference on Luminescence (ICL 93)&lt;br/&gt;Aug 09-13, 1993&lt;br/&gt;Univ connecticut, storrs, ct&lt;br/&gt;Univ connecticut; opt soc amer; amer phys soc; ieee, laser &amp; electro opt soc; int union pure &amp; appl phys; int sci fdn; univ connecticut res fdn&lt;br/&gt;3</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Markelz, A.

We find that the transmission of the fundamental, and the samples&#039; DC conductivity, decrease with increasing incident intensity, indicating a large rise in the scattering rate. Using the intensity-dependent transmission to account for absorption in the sample is not sufficient to recover a cubic power law for the third-harmonic intensity. In addition, given the increased scattering rate indicated by the conductivity data, the bulk free-carrier chi(3) due to non-parabolicity should decrease dramatically with increasing fundamental intensity, contrary to our results. Thus, non-parabolicity alone cannot account for the observed third-harmonic response.&lt;/p&gt;</style></abstract><accession-num><style face="normal" font="default" size="100%">WOS:A1994NM75300063</style></accession-num><notes><style face="normal" font="default" size="100%">Sherwin, Mark S/Q-4762-2017&lt;br/&gt;Sherwin, Mark S/0000-0002-3869-1893; Markelz, Andrea/0000-0003-0443-4319&lt;br/&gt;S&lt;br/&gt;8th International Conference on Hot Carriers in Semiconductors&lt;br/&gt;Aug 16-20, 1993&lt;br/&gt;Oxford univ, oxford, england&lt;br/&gt;Sci &amp; engn res council; royal soc; brit council; oxford univ&lt;br/&gt;4</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>10</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Sherwin, M.
