Technique For Video Compression By Projection Onto Convex Sets, P. Santago, Sarah A. Rajala

Sarah A. Rajala

This paper describes a video compression technique which utilizes the alternating projection theorem for convex sets. The image to be transmitted is determined to be in certain convex sets and parameters defining these sets are sent. The receiver can then use the method of successive projections to locate an image which is in the intersection of the sets. If the intersection is small then the image determined should be close to the desired image. The coder can be made more robust by easily adding additional convex sets or using it in conjunction with other coding schemes such as motion compensation.

Professorial Activism, Ali Khan

Ali Khan

Teaching law as science is morally confusing, if not dangerous. Supporting human laws on "scientific grounds" remains a popular, self-serving means to stunt a vigorous moral dialogue; it is a convenient route to escape an otherwise difficult moral terrain.

Fast Method For Calculating The Self-Consistent Electronic Structure Of Random Alloys, Duane D. Johnson, F. J. Pinski, G. M. Stocks

Duane D. Johnson

We describe a computationally efficient method for performing self-consistent-field calculations of the electronic structure of random solid-solution alloys within the multiple-scattering coherent-potential-approximation formalism (KKR-CPA). We utilize a cluster method for solving the KKR-CPA equations and integrate along a contour in the complex-energy plane to reconstruct the single-site electronic densities.

The Electronic Properties Of Ar And Xe Under Pressure, Richard Alan Lesar

Richard Alan Lesar

A simple model for calculating ground- and excited-state properties of molecular and rare-gas crystals is presented. The electrons are considered to be tightly bound to their molecular or atomic sites and the effects of the crystal potential, calculated with local-density funcationals, are treated as a perturbation of the molecules or atoms. Results for Ar to 500 kbar show that the ground-state atoms compress as the pressure is increased and that there is a gradual increase in excition energies. Preliminary results on ground-state Xe to 1.5 Mbar show that, to about 1 Mbar, the electronic distributions of the Xe atoms compress, …

Characterization Of The Transport Of Oxaloacetate By Pea Leaf Mitochondria, David J. Oliver, Griffin H. Walker

David J. Oliver

Mitochondria isolated from pea (Pisum sativum L.) leaves are able to transport the keto acid, oxaloacetate, from the reaction medium into he mitochondrial matrix at high rates. The rate of uptake by the mitochondria was measured as the rate of disappearance of oxaloacetate from the reaction medium as it was reduced by matrix malate dehydrogenase using NADH provided by glycine oxidation. The oxaloacetate transporter was identifed as being distinct from the dicarboxylate and the α-ketoglutarate transporters because of its inhibitor sensitivities and its inability to interact with other potential substrates. Phthalonate and phthalate were competitive inhibitors of oxaloacetate transport with …

Theoretical Study Of Silylene Insertion Into N-H, O-H, F-H, P-H, S-H, And Cl-H Bonds, Krishnan Raghavachari, Jayaraman Chandrasekhar, Mark S. Gordon, Ken Dykema

Mark S. Gordon

The potential energy surfaces for the insertion reactions of silylene into NH3, Hp, HF, PH3, H2S, and HCl have been characterized in detail by using ab initio molecular orbital theory, including electron correlation and zero-point corrections. All the interactions involve the initial formation of a donor-acceptor complex followed by a proton shift via an unsymmetrical high-energy transition state. The binding energies of the complexes as well as the rearrangement barriers for the hydrogen migration of these complexes to give the normal valent compounds have been calculated in all cases. The complex between SiH2 and NH3 exists in a deep minimum …

Ab Initio Study Of The Insertions Of Methylene And Silylene Into Methane, Silane, And Hydrogen, Mark S. Gordon, David R. Gano

Mark S. Gordon

The transition states for several insertion reactions have been determined at the 3-21G level of theory. While the insertions of CH2 and SiH2 into the CH and SiH bonds of methane and silane, respectively, all have nonzero SCF barriers, only the insertion of silylene into methane retains a nonzero barrier when third-order Moller-Plesset perturbation theory corrections are included with the 6-31G* basis set. The intrinsic reaction coordinates for the carbene and silylene insertions into methane are used to provide a pictorial view of these reactions and to relate the calculations to earlier studies. The insertion of silylene into H2 is …

Electron-Gas Plus Damped-Dispersion Model For Intermolecular Forces. The Rare-Gas And H,-He, H,-Ne, And H,-Ar Potentials, Richard Alan Lesar

Richard Alan Lesar

The modified Gordon-Kim (MGK) electron-gas model for the calculation of the short-range repulsive interactions between closed-shell atoms and molecules is used with a damped-dispersion term of a form suggested by Hepburn et al. to calculate the intermolecular potentials between the rare-gas atoms and H,-He, H2-Ne, and H,-Ar. The damping function for the dispersion energies is found by comparison with the experimental Ar-Ar potential and is then used without change for all other interactions. Except for interactions involving Ne atoms, the results for the atom-atom interactions are uniformly quite good, with an average deviation from experiment in the position of the …

Process For The Preparation Of Protein Isolates Of Improved Quality From Vegetable Protein Sources, Lawrence A. Johnson, Hwei-Mei Wen

Lawrence A. Johnson

Protein isolates are recovered from vegetable protein sources, such as sunflower meal, by extracting the meal with an alkali solution in the presence of an alkali metal borohydride, and then acid precipitating the resulting aqueous protein extract phase to produce a protein isolate. Typically, the alkali metal borohydride is employed in an amount of at least about 20 ppm, based on the combined weight of vegetable meal and alkali solution. Protein isolates produced by this process exhibit improved color, palatability and/or nutritional value, and comprise highly desirable additives for food products, animal foods, etc.

Factors Explaining The Use Of Health Care Services By The Elderly, Paula Diehr, Connie Evashwick

Paula Diehr

The Anderson model of health services utilization, which relates use of service to predisposing, enabling, and need factors, has not often been applied to an elderly population. In this study, the factors of the Andersen model were used prospectively to predict utilization for a population sample of 1,317 elderly persons. Taken alone, the NEED construct was the most important single predictor of use of physician services, hospitalizations, ambulatory care, and home care. PREDISPOSING factors were better predictors of the use of dental services. Some of the variables studied were not related to utilization in the direction that would have been …

Pseudodimensional Variation And Tricriticality Of Potts Models By Hierarchical Breaking Of Translational Invariance, Miron Kaufman, Mehran Kardar

Miron Kaufman

Potts models with equivalent- and nearest-neighbor interactions are solved exactly on Cayley trees. A parameter D is identified that plays a role similar to the spatial dimension on Bravais lattices. Breaking translational symmetry by the Cayley-tree hierarchy reduces D, leading to a changeover in the order of the phase transition via a novel tricritical point.

Ab Initio Studies Of Hxypo And Xypoh Molecules, Mark S. Gordon, Jerry A. Boatz, Michael W. Schmidt

Mark S. Gordon

Molecular orbital calculations have been carried out on a sequence of HXYPOH molecules, with X and Y = H, CH3, NH2, OH, OCH3, and F. The molecular structures are predicted with the ST0-2G* basis set. For the prediction of energies of isomerization to XYPOH species, single-point 3-21G* and 6-31G* calculations were used. The molecular dissociation energies of HXYPO to HPO + XY and to XPO + HY were calculated by augmenting the latter two basis sets with MP2 and MP3 perturbation corrections.

Hydrogen Abstractions By Triplet Methylene And Silylene, Mark S. Gordon

Mark S. Gordon

While the most common reactions of singlet methylenes are insertions into Y -H or multiple bonds, 1-3 triplet methylenes tend to abstract hydrogens from Y -H bonds. 1·2 Singlet silylenes are also known to insert,4-6 while little is known about the corresponding triplets. Several theoretical papers have been devoted to analyses of the insertions of singlet CH/-12 and SiHP-15 into a variety of bonds and the abstractions of hydrogen from H216-20 and CH417 by triplet methylene. Ab initio calculations including correlation predict that carbenes insert into Y-H9•11 ·12·15 bonds with no barrier, in agreement with the prevailing experimental evidence;1·2 however, …

Spin Systems On Hierarchical Lattices. Ii. Some Examples Of Soluble Models, Miron Kaufman, Robert B. Griffiths

Miron Kaufman

Several examples are given of soluble models of phase-transition phenomena utilizing classical discrete spin systems with nearest-neighbor interaction on hierarchical lattices. These include critical exponents which depend continuously on a parameter, the Potts model on a lattice with two different coupling constants, surface tension, and excess free energy of a line of defects. In each case we point out similarities and differences with a corresponding Bravais-lattice model.
