description: Рассматриваются проблемы конструирования и технологии изготовления защитных устройств на базе СВЧ монолитных интегральных схем (МИС), выполненных на GaAs. В процессе работы обоснован выбор элементной базы в виде pin диодов и реализована технология их изготовления с помощью газофазной эпитаксии. Основная часть работы посвящена разработке технологии создания низкоомных и малоиндуктивных шин металлизации на базе сквозных металлизированных отверстий, соединяющих элементы на лицевой стороне интегральных схем с металлизацией обратной стороны. Особое внимание уделено проектированию оптимальных геометрических размеров проводящих линий МИС защитных устройств на базе требований по волновому сопротивлению и фазовому набегу. Полученные электрические параметры СВЧ МИС удовлетворяют функциональному назначению защитных устройств для частот 10 ГГц.

description: Для работы гиратора на основе двухслойной магнитострикционно-пьезоэлектрической структуры требуется внешнее подмагничивающее поле. В данной работе рассмотрена слоистая структура при использовании неоднородной магнитной компоненты, позволяющей получить внутреннее подмагничивающее поле и отказаться от использования внешнего постоянного магнитного поля. В результате конструкция устройств на основе гиратора упрощается. В данной работе применена магнитная компонента на основе никель-цинкового феррита и метгласа. Анализ полученных данных показывает, что слоистая структура никель-цинковый феррит—метглас—ЦТС—метглас—никель-цинковый феррит обладает гираторными свойствами, заключающимися в зависимости выходной емкости от входной индуктивности.

description: The Galactic center is the most active site of star formation in the Milky Way Galaxy, where particularly high-mass stars have formed very recently and are still forming today. However, since we are looking at the Galactic center through the Galactic disk, knowledge of extinction is crucial when studying this region. The Arches cluster is a young, massive starburst cluster near the Galactic center. We observed the Arches cluster out to its tidal radius using Ks-band imaging obtained with NAOS/CONICA at the VLT combined with Subaro/Cisco J-band data to gain a full understanding of the cluster mass distribution. We show that the determination of the mass of the most massive star in the Arches cluster, which had been used in previous studies to establish an upper mass limit for the star formation process in the Milky Way, strongly depends on the assumed slope of the extinction law. Assuming the two regimes of widely used infrared extinction laws, we show that the difference can reach up to 30% for individually derived stellar masses and Delta AKs ~ 1 magnitude in acquired Ks-band extinction, while the present-day mass function slope changes by ~ 0.17 dex. The present-day mass function slope derived assuming the more recent extinction law increases from a flat slope of alpha_{Nishi}=-1.50 \pm0.35 in the core (r<0.2 pc) to alpha_{Nishi}=-2.21 \pm0.27 in the intermediate annulus (0.2

description: We investigate quantum state reconstruction of a superconducting qubit threaded by an Aharonov-Bohm flux, with particular attention to the local geometric phase. A state reconstruction scheme is introduced with a proper account of the local geometric phase generated by Faraday's law of induction. Our scheme is based on measurement of three complementary quantities, that is, the extra charge and two local currents. Incorporating time-reversal symmetry and the Faraday's law, we show that the full density matrix can be reconstructed without ambiguity in the choice of gauge. This procedure clearly demonstrates that the quantum Faraday effect plays an essential role in the dynamics of a quantum system that involves Aharonov-Bohm flux.

description: Optics is an exciting route for the next generation of computing hardware for machine learning, promising several orders of magnitude enhancement in both computational speed and energy efficiency. However, to reach the full capacity of an optical neural network it is necessary that the computing not only for the inference, but also for the training be implemented optically. The primary algorithm for training a neural network is backpropagation, in which the calculation is performed in the order opposite to the information flow for inference. While straightforward in a digital computer, optical implementation of backpropagation has so far remained elusive, particularly because of the conflicting requirements for the optical element that implements the nonlinear activation function. In this work, we address this challenge for the first time with a surprisingly simple and generic scheme. Saturable absorbers are employed for the role of the activation units, and the required properties are achieved through a pump-probe process, in which the forward propagating signal acts as the pump and backward as the probe. Our approach is adaptable to various analog platforms, materials, and network structures, and it demonstrates the possibility of constructing neural networks entirely reliant on analog optical processes for both training and inference tasks.

description: Effects of coupling between a molecular exciton and a surface plasmon (exciton-plasmon coupling) on the luminescence properties of the molecule and the surface plasmons are investigated using the nonequilibrium Green's function method. Molecular absorption and enhancement by molecular electronic and vibrational modes (molecular modes) lead to dip and peak structures in the luminescence spectra of the surface plasmons. These structures will correspond to the peak and dip structures observed in a recent experiment. We found that in addition to the molecular dynamics, the re-absorption by the surface plasmons plays important roles in determining the luminescence spectral profiles.

description: Hanbury-Brown and Twiss (HBT) effect is the foundation for stellar intensity interferometry. However, it is a phase insensitive two-photon interference effect. In this paper, we extend the HBT interferometer by mixing two phase-coherent input fields with coherent auxiliary fields before intensity correlation measurement and achieve phase sensitive two-photon interference so as to measure the complete complex second-order coherence function of the input fields. This practical scheme paves the way for synthetic aperture imaging for astronomical applications in optical regime. Pulsed input fields is also tested for potential remote sensing and ranging applications. We discuss the condition to implement recently proposed entanglement-based telescopy scheme with the more realistic cw broadband anti-bunched light fields.

Semi-classical understanding of flux quantization in superconductors

description: Like electric charge, magnetic flux is also quantised. Theoretically, one can show that the flux quantum must be h/e, as observed in the quantum Hall effect. However, in the superconducting systems, the flux quantum is experimentally observed as h/2e. There is no fundamental explanation for the empirical result. In this article, we argue that this phenomenon is fundamentally linked to the nonlocality problem of the Aharonov-Bohm effect and present a new semi-classical explanation for the magnetic flux quantum in superconductivity. This work will also show why the flux quantum should be h/e in the case of the quantum Hall effect.

description: We use AdS/CFT to construct the gravitational dual of a 5D CFT in the background of a non-extremal rotating black hole. Our boundary conditions are such that the vacuum state of the dual CFT corresponds to the Unruh state. We extract the expectation value of the stress tensor of the dual CFT using holographic renormalisation and show that it is stationary and regular on both the future and the past event horizons. The energy density of the CFT is found to be negative everywhere in our domain and we argue that this can be understood as a vacuum polarisation effect. We construct the solutions by numerically solving the elliptic Einstein--DeTurck equation for stationary Lorentzian spacetimes with Killing horizons.

description: The material that is ejected in a common-envelope (CE) phase in a close binary system provides an ideal environment for dust formation. By constructing a simple toy model to describe the evolution of the density and the temperature of CE ejecta and using the \emph{AGBDUST} code to model dust formation, we show that dust can form efficiently in this environment. The actual dust masses produced in the CE ejecta depend strongly on their temperature and density evolution. We estimate the total dust masses produced by CE evolution by means of a population synthesis code and show that, compared to dust production in AGB stars, the dust produced in CE ejecta may be quite significant and could even dominate under certain circumstances.

Measurements of drag coefficients for falling and rising spheres in free motion
Creators: name: Preukschat, A. Werner
Publisher: name: California Institute of Technology
Year: 1962
Subjects: Aeronautics

description: The purpose of this thesis is to investigate the drag coefficient of spheres in free motion, falling and rising, in water.

Following the introduction the test set-up, sphere release mechanism, spheres and timing device and recorder are described.

Section 3 gives the results of the drag coefficient measurements for free falling spheres which show good agreement with the known measurements, quoted, for instance, in the Handbuch der Experimentalphysik.

Section 4 deals with the measurement of drag coefficients of free-rising spheres. It was found that the freely rising spheres move in an oscillatory path of which wavelength and amplitude depend on the ratio of sphere density and water density.

The local drag coefficient of the spheres was measured to be the same as for falling spheres. It was found to be independent of the sphere motion.

No critical Reynolds number was found for the onset of the oscillatory motion of the sphere. The oscillatory motion appeared to be independent of initial disturbances of the sphere motion.

From photographs of the sphere paths Strouhal numbers were formed which are about one third the value given for circular cylinders in the same Reynolds number range.

A theoretical oscillatory force coefficient, based on a force balance on the sphere, was obtained. It was found to be of the same order of magnitude as the correspondent, actually measured oscillatory force coefficient on a circular cylinder.

The Strouhal number based on the main theoretical frequency was found to be four times as high as the one calculated from the frequency of the sphere path. It could be, dependent on the sphere density, as high as twice the Strouhal number found for circular cylinders in the same Reynolds number range.

description: A new and thorough derivation of linear-response subsystem time-dependent density functional theory (TD-DFT) is presented and analyzed in detail. Two equivalent derivations are presented and naturally yield self-consistent subsystem TD-DFT equations. One reduces to the subsystem TD-DFT formalism of Neugebauer [J. Chem. Phys. 126, 134116 (2007)10.1063/1.2713754]. The other yields Dyson type equations involving three types of subsystem response functions: coupled, uncoupled, and Kohn-Sham. The Dyson type equations for subsystem TD-DFT are derived here for the first time. The response function formalism reveals previously hidden qualities and complications of subsystem TD-DFT compared with the regular TD-DFT of the supersystem. For example, analysis of the pole structure of the subsystem response functions shows that each function contains information about the electronic spectrum of the entire supersystem. In addition, comparison of the subsystem and supersystem response functions shows that, while the correlated response is subsystem additive, the Kohn-Sham response is not. Comparison with the non-subjective partition DFT theory shows that this non-additivity is largely an artifact introduced by the subjective nature of the density partitioning in subsystem DFT.

Acidity, basicity, and ion-molecule reactions of arsine in the gas phase by ion cyclotron resonance spectroscopy
Creators: name: Wyatt, Robert Howard
Publisher: name: California Institute of Technology
Year: 1971
Subjects: Chemistry

description: The ion-molecule reactions of arsine, both pure and in binary mixtures with several other molecules, have been investigated by ion cyclotron resonance spectroscopy. Reaction pathways, product distributions, and rate constants have been determined for the ion-molecule reactions for both positive and, to a lesser extent, negative ions. Arsine fragment ions condense with neutral AsH_3 to generate product ions containing two and, on further reaction, three atoms of arsenic. In the process of condensation, one or two molecules of H_2 are expelled. The formation of AsH_4^+ occurs from AsH_3^+ which does not undergo condensation reactions to any significant extent. Where possible, thermochemical data have been determined, including the gas phase acidity, PA(AsH_2^-) = 356 ± 6 kcal/mole, and basicity, PA(AsH_3) = 175 ± 5 kcal/mole, of AsH_3. Observation of gas phase nucleophilic displacement reactions involving AsH_3 as a nucleophile have allowed limits to be placed on the basicity of AsH_3 toward a soft acid, CH_3^+. The implications of these results are discussed and the ion-molecule reactions of AsH_3 are compared with those of other hydrides.

description: We study three classes of continuous time Markov processes (inclusion process, exclusion process, independent walkers) and a family of interacting diffusions (Brownian energy process). For each model we define a boundary driven process which is obtained by placing the system in contact with proper reservoirs, working at different particles densities or different temperatures. We show that all the models are exactly solvable by duality, using a dual process with absorbing boundaries. The solution does also apply to the so-called thermalization limit in which particles or energy is instantaneously redistributed among sites. The results shows that duality is a versatile tool for analyzing stochastic models of transport, while the analysis in the literature has been so far limited to particular instances. Long-range correlations naturally emerge as a result of the interaction of dual particles at the microscopic level and the explicit computations of covariances match, in the scaling limit, the predictions of the macroscopic fluctuation theory.

description: We propose a faster digital quantum algorithm for portfolio optimization using the digitized-counterdiabatic quantum optimization (DCQO) paradigm in the impulse regime, that is, where the counterdiabatic terms are dominant. Our approach notably reduces the circuit depth requirement of the algorithm and enhances the solution accuracy, making it suitable for current quantum processors. We apply this protocol to a real-case scenario of portfolio optimization with 20 assets, using purely quantum and hybrid classical-quantum paradigms. We experimentally demonstrate the advantages of our protocol using up to 20 qubits on an IonQ trapped-ion quantum computer. By benchmarking our method against the standard quantum approximate optimization algorithm and finite-time digitized-adiabatic algorithms, we obtain a significant reduction in the circuit depth by factors of 2.5 to 40, while minimizing the dependence on the classical optimization subroutine. Besides portfolio optimization, the proposed method is applicable to a large class of combinatorial optimization problems.

description: We investigated the characteristics of the spin fluctuations mediated superconductivity employing the Eliashberg formalism. The effective interaction between electrons was modeled in terms of the spin susceptibility measured by the inelastic neutron scattering experiments on single crystal La2-xSrxCuO4 superconductors. The diagonal self-energy and off-diagonal self-energy were calculated by solving the coupled Eliashberg equation self-consistently for chosen spin susceptibility and tight-binding dispersion of electrons. The full momentum and frequency dependence of the self-energy is presented for the optimal, overdoped, and underdoped LSCO cuprates in superconductive state. These results may be compared with the experimentally deduced self-energy from ARPES experiments.

description: We consider strongly interacting systems of effective spins, subject to dissipative spin-flip processes associated with optical pumping. We predict the existence of novel magnetic phases in the steady-state of this system, which emerge due to the competition between coherent and dissipative processes. Specifically, for strongly anisotropic spin-spin interactions, we find ferromagnetic, antiferromagnetic, spin-density-wave, and staggered-XY steady states, which are separated by nonequilibrium phase transitions meeting at a Lifshitz point. These transitions are accompanied by quantum correlations, resulting in spin squeezing. Experimental implementations in ultracold atoms and trapped ions are discussed.

description: We present a minimal Landau theory of plastic-to-crystal phase transitions in which the key components are a multipole-moment order parameter that describes the orientational ordering of the constituent molecules, coupling between such order parameter and elastic strains, and thermal expansion. We illustrate the theory with the simplest non-trivial model in which the orientational ordering is described by a quadrupole moment, and use such model to calculate barocaloric effects in plastic crystals that are driven by hydrostatic pressure. The model captures characteristic features of plastic-to-crystal phase transitions, namely, large changes in volume and entropy at the transition, as well as the linear dependence of the transition temperature with pressure. We identify temperature regions in the barocaloric response associated with the individual plastic and crystal phases, and those involving the phase transition. Our model is in overall agreement with previous experiments in powdered samples of fullerite C$_{60}$, and predicts peak isothermal entropy changes of $\sim90 \,{\rm J K^{-1} kg^{-1}}$ and peak adiabatic temperature changes of $\sim35 \,{\rm K}$ under $0.60\,$GPa at $265\,$K in fullerite single crystals.

The material collected on each stage was analyzed for nitrate by direct vaporization into a chemiluminescent analyzer, sensitive at nanogram levels. The method responds to inorganic nitrate compounds which vaporize or decompose below about 1200°C. The coastal nitrate size distribution consists mainly of particles which have diameters greater than 2.0 µM, whereas the nitrate in the agricultural region is found primarily in the submicron range. The urban location, exhibiting characteristics of both coastal and agricultural regions, was bimodal about the 1-2 µm range. It is believed that the submicron aerosol is ammonium nitrate while the larger size fraction is sodium nitrate.

description: We present the Julia package ToricAtiyahBott.jl, providing an easy way to perform the Atiyah-Bott formula on the moduli space of genus $0$ stable maps $\overline{M}_{0,m}(X,β)$ where $X$ is any smooth projective toric variety, and $β$ is any effective $1$-cycle. The list of the supported cohomological cycles contains the most common ones, and it is extensible. We provide a detailed explanation of the algorithm together with many examples and applications. The toric variety $X$, as well as the cohomology class $β$, must be defined using the package Oscar.jl.

description: We theoretically study phonon-drag contribution to the thermoelectric power and hot-electron energy-loss rate in a Rashba spin-orbit coupled two-dimensional electron system (2DES) in the Bloch-Gruneisen (BG) regime. We assume that electrons interact with longitudinal acoustic phonons through deformation potential and with both longitudinal and transverse acoustic phonons through piezoelectric potential. Effect of the Rashba spin-orbit interaction on magnitude and temperature dependence of the phonon-drag thermoelectric power and hot-electron energy-loss rate are discussed. We numerically extract the exponent of temperature dependence of the phonon-drag thermopower and the energy-loss rate. We find the exponents are strongly suppressed due to the presence of the Rashba spin-orbit coupling.

A new Miocene mammalian fauna from the Caliente Mountains, California
Creators: name: Dougherty, Jack Francis

Subjects: subject: Geology
subject: FOS: Earth and related environmental sciences

description: Fossil mammalian remains from the Caliente Mountain region, San Luis Obispo County, California, were first found by John B. Stevens in 1928 in red beds associated with basalt flows near Padrones Spring. The material, fragments of a merycodont jaw, was presented to the California Institute at that time. The importance of the Caliente Mountain marine section is emphasized by Reed and Hollister in their discussion of the Caliente Miocene. As recognized by Reed and Hollister, “The great difference in facies of these beds permits the determination of the interrelation of mammalian, mollusk, and foraminiferal zones, a task that is not easy in many districts.” The present study was undertaken, therefore, with a view to obtaining a mammalian fauna from the region and establishing its relationships to the Miocene molluscan and foraminiferal zones. It is hoped also that such a study might bring out more clearly the relationships of the invertebrate and vertebrate time scales for at least this stage of the Miocene.
An Investigation of the Effects of a Sharp Velocity Gradient of the Flexure-Torsion Flutter Speed of an Airfoil

description: This report covers the results of an experimental investigation of the effects of a velocity gradient on the flexure-torsion flutter speed of a NACA 0006 airfoil suspended by means of springs.

The presence of the velocity gradient produced no significant change in the speed at which the airfoil commenced normal self-excited oscillations. Oscillations of a torsional nature were found to occur at speeds considerably below the normal flutter speed. The causes of these torsional oscillations were not fully ascertained. It is reasoned however that they were due to flow conditions other than the presence of the velocity gradient.

description: In previous work, we introduced a new framework to treat large scale backreaction effects due to small scale inhomogeneities in general relativity. We considered one-parameter families of spacetimes for which such backreaction effects can occur, and we proved that, provided the weak energy condition on matter is satisfied, the leading effect of small scale inhomogeneities on large scale dynamics is to produce a traceless effective stress-energy tensor that itself satisfies the weak energy condition. In this work, we illustrate the nature of our framework by providing two explicit examples of one-parameter families with backreaction. The first, based on previous work of Berger, is a family of polarized vacuum Gowdy spacetimes on a torus, which satisfies all of the assumptions of our framework. As the parameter approaches its limiting value, the metric uniformly approaches a smooth background metric, but spacetime derivatives of the deviation of the metric from the background metric do not converge uniformly to zero. The limiting metric has nontrivial backreaction from the small scale inhomogeneities, with an effective stress-energy that is traceless and satisfies the weak energy condition, in accord with our theorems. Our second one-parameter family consists of metrics which have a uniform Friedmann-Lemaitre-Robertson-Walker limit. This family satisfies all of our assumptions with the exception of the weak energy condition for matter. In this case, the limiting metric has an effective stress-energy tensor which is not traceless. We emphasize the importance of imposing energy conditions on matter in studies of backreaction.

description: The evolution of the curvature perturbation after multi-field inflation is studied in the light of the curvaton mechanism. Past numerical studies show that many-field inflation causes significant evolution of the curvature perturbation after inflation, which generates significant non-Gaussianity at the same time. We reveal the underlying mechanism of the evolution and show that the evolution is possible in a typical two-field inflation model.

description: В настоящее время обостряется проблема организации и регулирования движения беспилотных воздушных судов (БВС). Наиболее эффективным средством обнаружения и слежения за БВС являются радары. Сама по себе задача обнаружения низколетящих малоразмерных целей на фоне подстилающей поверхности является крайне сложной. Необходимо выделить слабый сигнал малоразмерной цели из аддитивной смеси полезного сигнала, мощных пассивных помех и шума. Задача решается радиолокационными станциями с высоким энергопотенциалом, реализующими при обработке отражений эффективные алгоритмы селекции движущихся целей на фоне помех. Стоимость подобных радиолокаторов весьма значительна. Для больших площадей покрытия требуются решения на базе систем из недорогих радиолокационных станций. В статье приводится описание реализаций малогабаритных РЛС X/L-диапазона для обнаружения/сопровождения БВС. Представлены результаты их экспериментальной проверки.

description: Стремительное развитие малых БПЛА представляет серьезную угрозу для защиты важной инфраструктуры и стратегических объектов, а также безопасности населения. Современные средства полуактивной радиолокации являются перспективным решением задачи обнаружения БПЛА и предупреждения потенциальной угрозы. При этом распознавание малых БПЛА представляет собой сложную задачу, т.к. они имеют схожие с другими целями, в частности с птицами, радиолокационные характеристики и параметры движения. В статье представлены результаты экспериментальных исследований эхосигналов малых БПЛА, наблюдаемых пассивным когерентным локатором, использующим сигналы цифрового эфирного телевидения стандарта DVB-T2 в качестве радиолокационного подсвета. Показаны отличия в характере отклика взаимной функции неопределенности на сигнал, отраженный от БПЛА с различной конфигурацией лопастей пропеллеров. Определены информативные признаки, которые могут быть использованы для распознавания БПЛА в полуактивных РЛС.
