Electron Heat Flow Due To Magnetic Field Fluctuations, Jeong-Young Ji, Gunyoung Park, Sung Sik Kim, Eric D. Held

All Physics Faculty Publications

Radial heat transport induced by magnetic field line fluctuations is obtained from the integral parallel heat flow closure for arbitrary collisionality. The parallel heat flow and its radial component are computed for a single harmonic sinusoidal field line perturbation. In the collisional and collisionless limits, averaging the heat flow over an unperturbed surface yields Rechester-Rosenbluth like formulae with quantitative factors. The single harmonic result is generalized to multiple harmonics given a spectrum of small magnetic perturbations. In the collisionless limit, the heat and particle transport relations are also derived. © 2016 IOP Publishing Ltd.

Canonical Models Of Dielectric Response, D. Mark Riffe

All Physics Faculty Publications

The interaction of electromagnetic fields with a solid is characterized by several interconnected response functions: the dielectric function ε(ω), index of refraction N(ω), conductivity σ(ω), and optical impedance Z(ω). Here we utilize three canonical models of dielectric response -- the damped harmonic oscillator, Debye polarization response, and the Drude model -- to discuss these four optical response functions. Special emphasis is devoted to the response of a Drude metal. Our main focus is on electromagnetic wave propagation through a material. We also discuss the relaxation of charge fluctuations within the context of the three canonical models of response.

Variable Van Der Waals Radii Derived From A Hybrid Gaussian Charge Distribution Model For Continuum-Solvent Electrostatic Calculations, Renlong Ye, Xuemei Nie, Chung Wong, Xuedong Gong, Yan Wang, Thomas Heine, Baojing Zhou

Chemistry & Biochemistry Faculty Works

We introduce a hybrid Gaussian charge distribution model (HGM) that partitions the molecular electron density into overlapping spherical atomic domains. The semi-empirical HGM consists of atom-centered spherical Gaussian functions and discrete point charges, which are optimized to reproduce the electrostatic potential on the molecular surface as well as the number of electrons in atom-centered and certain off-atom-centered spherical regions as closely as possible. In contrast, our previous Gaussian charge distribution model [J. Chem. Phys. 129, 014509 (2008)] contained only spherical Gaussian functions and was not required to reproduce the number of electrons in off-atom-centered regions. Variable van der Waals (vdW) …

The Schwarzschild Solution And Timelike Geodesics, Matthew Ross

Physics Capstone Projects

General Relativity is the standard theory of the gravitational interaction. It allows us to cal- culate the motions and interactions of particles in a non-Euclidean space-time. This presentation will present the derivation of the Schwarzschild metric tensor field by finding a solution of the Einstein Equation for a non-rotating, static vacuum. A general form of the metric for a static, spherically symmetric spacetime will be used to calculate the Riemann curvature tensor and sub- sequently the Ricci tensor and Ricci scalar which will then be used to find a vaccum solution to the Einstein Equation. Once the solutions of the …

Some Results On Analysis And Implementation Of Hc-128 Stream Cipher., Shashwat Raizada Dr.

Doctoral Theses

The HC-128 stream cipher is a successful entrant in the eStream candidate list (software profile) and is the lighter variant of HC-256 stream cipher. Apart from the analysis by the designer of the cipher (Hongjun Wu) to conjecture the security of this cipher, there are only a few other observations on this cipher despite being the focus of researchers during the three phases of eStream evaluation and later efforts in the community. Till date none of the security claims in favor of HC-128 by the designer could be broken. One may expect HC-128 stream cipher to be popular in commercial …

Effect Of Branch-Chain Elongation On Physicochemical Properties And Digestibility Characterization Of Waxy Corn Starch, He Jian, Wang Ren, Zhang Hao, Zhou Xing, Chen Zhengxing

Food and Machinery

Waxy corn starch (WCS) was modified by amylosucrase (AS). The effect of starch elongation degree on the digestibility and physicochemical properties of modified waxy corn starch (WCS) was investigated. The results showed that under the given reaction condition, enzymatic reaction could be fitted by a logarithmic mathematical model. Compared with native starch, the modified WCSs expressed a continuous matrix structure, and the packing arrangement of crystalline converted from A-type into B-type. With transglycosylation rate (TR) increasing, an increased tendency of proportion of Fr I (DP＞30) was observed, whereas the contents of Fr III (DP＜13) was significantly decreased. In vitro test …

Recent Advances In Development And Applications Of The Mixed Quantum/Classical Theory For Inelastic Scattering, Dmitri Babikov, Alexander Semenov

Chemistry Faculty Research and Publications

A mixed quantum/classical approach to inelastic scattering (MQCT) is developed in which the relative motion of two collision partners is treated classically, and the rotational and vibrational motion of each molecule is treated quantum mechanically. The cases of molecule + atom and molecule + molecule are considered including diatomics, symmetric-top rotors, and asymmetric-top rotor molecules. Phase information is taken into consideration, permitting calculations of elastic and inelastic, total and differential cross sections for excitation and quenching. The method is numerically efficient and intrinsically parallel. The scaling law of MQCT is favorable, which enables calculations at high collision energies and for …

Microwave Measurements Of The Tropolone-Formic Acid Doubly Hydrogen Bonded Dimer, Aaron M. Pejlovas, Agapito Serrato, Wei Lin, Stephen G. Kukolich

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Chemistry)

The microwave spectrum was measured for the doubly hydrogen bonded dimer formed between tropolone and formic acid. The predicted symmetry of this dimer was C2v(M), and it was expected that the concerted proton tunneling motion would be observed. After measuring 25 a- and b-type rotational transitions, no splittings which could be associated with a concerted double proton tunneling motion were observed. The calculated barrier to the proton tunneling motion is near 15 000 cm-1, which would likely make the tunneling frequencies too small to observe in the microwave spectra. The rotational and centrifugal distortion constants determined from the measured transitions …

Is Socrates Dead (In Mathematics)?: The Role Of The Mathematics Teacher In Higher Education Now And For The Next Ten Years, Mary K. Landers

Bollinger-Rosado Teaching & Learning Effectiveness Symposium Proceedings

Socratic questioning is an important tool of the mathematical trade for mathematicians and students alike. Simply turning the crank" is not mathematics. Without the willingness and/or ability for Socratic thought new worlds of mathematics for the future may not be invented nor discovered. Therefore, future students of mathematics need not only be taught to learn from the past but to question toward the future as well. Consequently, the teacher of mathematics must fill a dual role:

a) that of purveyor of facts and methods for the application of those already established structures that comprise mathematical thought and b) that of …

Teaching Business Courses At Extended Campuses, William S. Sachs

Bollinger-Rosado Teaching & Learning Effectiveness Symposium Proceedings

Teaching business courses at extended campuses raises three main problems: a shortage of time available to students; the quality of academic skills of the student body; the relevancy of course material which syllabi and course outlines make mandatory. The author makes several recommendations to alleviate these problems.

Lastly, the role of professors is viewed from the perspective of a communication model. As experts in their respective fields, PhDs act as knowledge-transmitting mechanisms. Students play the role of receptors, which are the creators of individual learning. To facilitate this communication process between teachers and students, the paper suggests systematic research into …

Teaching Strategies For Today's College Classroom, Francis Herlehy Iii, Merodie A. Hancock

Bollinger-Rosado Teaching & Learning Effectiveness Symposium Proceedings

Everybody has something to say about teaching. Everyone has an opinion on the subject. This is probably because everyone has been on the receiving end of it.

It is a favorite pastime of students to compare and contrast their professors. Much, if not most, of what they have to say is of a personal nature. Conspicuous in its absence is anything of substance about their teaching.

Talk at faculty meetings isn't much better. You will hear about lighter teaching loads, smaller class sizes, and fewer committee assignments. Invariably, some intrepid instructor might even suggest the need for better instruction. Talk …

Teaching And Technology Techniques For Teachers In Online Learning Environments, Sallie J. Johnson

Bollinger-Rosado Teaching & Learning Effectiveness Symposium Proceedings

When developing and delivering instruction, whether online or not, the use of technology is secondary to well-designed learning goals and objectives. What distinguishes online instruction and technology in the classroom from entertainment or recreation is the conceptual development of teaching techniques based on solid learning theories. This paper proposes a conceptual framework for implementing teaching and technology techniques for online learning environments.

Tech'knowledge'y Anxiety, Francis Herlehy Iii, Merodie A. Hancock

Bollinger-Rosado Teaching & Learning Effectiveness Symposium Proceedings

There is a plethora of literature on educational software and hardware. Equally as much has been written about technology and the learning environment. Conspicuous in its absence is discussion of the liveware component of educational technology, the faculty member.

Changing educational technologies are threatening many faculty members' sense of security and even, in some cases, their very livelihoods. Those faculty members who are willing to face their concerns 'head-on' can learn to convert their apprehension into the motivation needed to make changes that will assure them of success in today's high technology, learning environment.

Evidence Of Dispersion And Refraction Of A Spectrally Broad Gravity Wave Packet In The Mesopause Region Observed By The Na Lidar And Mesospheric Temperature Mapper Above Logan, Utah, T. Yuan, C. J. Heale, J. B. Snively, Xuguang Cai, P.-D. Pautet, C. Fish, Y. Zhao, Michael J. Taylor, W. R. Pendleton Jr., V. Wickmar, N. J. Michell

All Physics Faculty Publications

Gravity wave packets excited by a source of finite duration and size possess a broad frequency and wave number spectrum and thus span a range of temporal and spatial scales. Observing at a single location relatively close to the source, the wave components with higher frequency and larger vertical wavelength dominate at earlier times and at higher altitudes, while the lower frequency components, with shorter vertical wavelength, dominate during the latter part of the propagation. Utilizing observations from the Na lidar at Utah State University and the nearby Mesospheric Temperature Mapper at Bear Lake Observatory (41.9ÁN, 111.4ÁW), we investigate a …
