description: Past numerical simulations and experiments of turbulence exhibit a hump in the inertial range, called the bottleneck effect. In this paper we show that sufficiently large inertial range (four decades) is required for an effective energy cascade. We propose that the bottleneck effect is due to the insufficient inertial range available in the reported simulations and experiments. To facilitate the turbulent energy transfer, the spectrum near Kolmogorov's dissipation wavenumber has a hump.

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Semiclassical path integral expression for a quantum system coupled to a harmonic bath is derived based on the stationary phase condition. It is discovered that the system path is non-Markovian. Most strikingly, the system path not only couples to its past (as in the Langevin equation), but also to its future, i.e. the equation of motion for the system is an integro-differential equation that involves all times. Numerical tests are performed to confirm that the future-involved term is indeed necessary. Because of the future-non-Markovian nature of the equation, the numerical solution cannot be obtained by iterative methods. Instead, root search algorithms must be employed.
UV pumping of hyperfine transitions in the light elements, with application to 21-cm hydrogen and 92-cm deuterium lines from the early universe

description: We present new analytic calculations of the coupling between ultraviolet resonance photons and the population of the hyperfine states in the light elements (H, D, He3+) which include several previously neglected physical processes. Among these are the backreaction of resonant scattering on the pumping radiation, the scattering of Ly_beta photons and the effect of local departure from pure Hubble flow. The application of the new treatment to the redshifted hydrogen 21 and deuterium 92 cm lines from the high-redshift universe results in an amplitude correction of up to an order of magnitude. We further show that the standard assumption that ultraviolet pumping drives the spin temperature towards the kinetic temperature does not hold for deuterium, whose spin temperature is generally negative.

description: Historically low prices in the conventional coffee market have caused financial and social hardship among coffee farmers. In the face of this crisis, specialty markets have attracted the attention of the international donor community. These market segments have shown consistent growth over the last decade and exhibit price premiums in international markets. Therefore, if higher prices are passed on to farmers, access to specialty markets could help to alleviate the crisis brought on by low prices in the conventional sector. The present study attempts to identify the factors that determine farmers' participation in specialized markets and whether participation in these markets leads to higher prices for farmers. A two-stage model is used to analyze farmers' marketing decisions and their effect on the prices received. This procedure allows us to control for the endogeneity bias introduced by the marketing choice. Our results indicate that farmers participating in the specialty coffee segment do in fact receive higher prices than those participating in conventional channels. Additionally, we find that participation in cooperatives has a positive impact on the probability that a farmer chooses to grow specialty coffee and analogously the prices that they receive. Based on these results it seems that efforts to increase participation in the specialty coffee segment and in cooperatives would help to lessen some of the hardships brought on by low prices in the conventional coffee sector.

description: This work reports on the production of Ag nanoparticles (AgNPs) in water solution based upon two-phase pulsed laser procedure for ophthalmological therapeutic approaches. In this case, the AgNPs should be less then 10 nm and have a narrow size distribution. Nanoparticles of this sized-scale are capable to penetrate the complex ocular barriers, ensuring effective non-invasive drug delivery to retina. In the first phase, AgNPs larger than 20 nm were fabricated via laser ablation of a Ag target under water by irradiation with a fundamental wavelength of 1064 nm generated by a Nd:YAG laser. During the second phase, to reduce the mean size of the as-obtained nanoparticles and properly adjust the size distribution, the water colloids were additionally irradiated by ultraviolet harmonics (355 nm and 266 nm) from the same laser source. The effect of the key laser parameters - wavelength, fluence and laser exposure time - upon the nanoparticles morphology was studied. The most suitable post-ablation treatment of initial colloids was obtained by consecutive irradiation with the third (355 nm) and the fourth (266 nm) harmonics of the fundamental laser wavelength. By using this approach synergistic effect between two mechanisms of light absorption by AgNPs was induced. As a result contaminant-free colloids of AgNPs with a size inferior to 10 nm and a quite narrow size distribution with a standard deviation of 1.6 nm were fabricated. The toxic effect of the as-produced AgNPs on Gram-positive and Gram-negative bacteria and Candida albicans was explored. The most efficient action was reached against Pseudomonas aeruginosa and Escherichia coli. Potential application of the synthesized AgNPs colloidal aqueous solutions with antimicrobial action as a non-invasive method for ocular infections prevention and treatment was proposed.

description: The double-cone ascending an inclined V-rail is a common exhibit used for demonstrating concepts related to center-of-mass in introductory physics courses. While the conceptual explanation is well-known--the widening of the ramp allows the center of mass of the cone to drop, overbalancing the increase in altitude due to the inclination of the ramp--there remains rich physical content waiting to be extracted through deeper exploration. Such an investigations seems to be absent from the literature. This article seeks to remedy the omission.

description: This paper's goal is to increase the understanding of the income and fiscal inequality trends in rural China. Using a comprehensive county-level panel dataset between 1993 and 2002, we describe the dynamic changes in national, regional and provincial inequality measures for income, fiscal spending and local revenues respectively. We examine how the coastal-inland gap, the inter-province gap, and the gap between poor and non-poor counties contribute to the growth of inequality, and devise a decomposition approach to investigate the order of inter-group inequality's contribution to the overall inequality in a multi-tier hierarchical economy. Our major finding reveals that after a turning point, 1998, most income and fiscal inequality trends started to grow together, yet at different rates. The pattern of fiscal inequality changes over time indicates that the budget constraint was not hardened after the 1994 fiscal reform. Strong evidence suggests that the inland gap between poor and non-poor counties contributed to the overall income inequality more than the coastal gap, but both decreased its contribution continuously in recent years. The order of their contributions to the overall fiscal spending inequality was reversed, implying that fiscal equalization policies, though in favor of inland areas, didn't work well in reducing the inland gap between poor and nonpoor counties.

description: The central goal of this paper is to establish two commonly available dimensionality reduction (DR) methods i.e. t-distributed Stochastic Neighbor Embedding (t-SNE) and Multidimensional Scaling (MDS) in Matlab and to observe their application in several datasets. These DR techniques are applied to nine different datasets namely CNAE9, Segmentation, Seeds, Pima Indians diabetes, Parkinsons, Movement Libras, Mammographic Masses, Knowledge, and Ionosphere acquired from UCI machine learning repository. By applying t-SNE and MDS algorithms, each dataset is transformed to the half of its original dimension by eliminating unnecessary features from the datasets. Subsequently, these datasets with reduced dimensions are fed into three supervised classification algorithms for classification. These classification algorithms are K Nearest Neighbors (KNN), Extended Nearest Neighbors (ENN), and Support Vector Machine (SVM). Again, all these algorithms are implemented in Matlab. The training and test data ratios are maintained as ninety percent: ten percent for each dataset. Upon accuracy observation, the efficiency for every dimensionality technique with availed classification algorithms is analyzed and the performance of each classifier is evaluated.

Tidal tails of open star clusters as probes to early gas expulsion I: A semi-analytic model

Publisher: name: arXiv
Year: 2020
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Star clusters form out of the densest parts of infrared dark clouds. The emergence of massive stars expels the residual gas, which has not formed stars yet. Gas expulsion lowers the gravitational potential of the embedded cluster, unbinding many of the cluster stars. These stars then move on their own trajectories in the external gravitational field of the Galaxy, forming a tidal tail. We investigate the formation and evolution of the tidal tail forming due to expulsion of primordial gas under various scenarios of gas expulsion to provide predictions for tidal tails around dynamically evolved (age > 100 Myr) galactic star clusters, which can be possibly detected by the Gaia mission. We provide a semi-analytical model for the tail evolution. We find that tidal tails released during gas expulsion have different kinematic properties than the tails gradually forming due to evaporation. The gas expulsion tidal tail shows non-monotonic expansion with time, where longer epochs of expansion are interspersed with shorter epochs of contraction. The tail thickness and velocity dispersions strongly, but not exactly periodically, vary with time. The times of minima of tail thickness and velocity dispersions are given only by the properties of the galactic potential, and not by the properties of the cluster. The estimates provided by the (semi-)analytical model for the extent of the tail, the minima of tail thickness, and velocity dispersions are in a very good agreement with the nbody6 simulations. This implies that the semi-analytic model can be used for estimating the properties of the gas expulsion tidal tail for a cluster of a given age and orbital parameters without the necessity of performing numerical simulations. A study with a more extended parameter space of the initial conditions is performed in the follow up paper.

description: Molecular line observations using a variety of tracers are often used to investigate the kinematic structure of molecular clouds. However, measurements of cloud velocity dispersions with different lines, even in the same region, often yield inconsistent results. The reasons for this disagreement are not entirely clear since molecular line observations are subject to a number of biases. In this paper, we untangle and investigate various factors that drive linewidth measurement biases by constructing synthetic position-position-velocity cubes for a variety of tracers from a suite of self-gravitating magnetohydrodynamic simulations of molecular clouds. We compare linewidths derived from synthetic observations of these data cubes to the true values in the simulations. We find that differences in linewidth as measured by different tracers are driven by a combination of density-dependent excitation, whereby tracers that are sensitive to higher densities sample smaller regions with smaller velocity dispersions, opacity broadening, especially for highly optically thick tracers such as CO, and finite resolution and sensitivity, which suppress the wings of emission lines. We find that, at fixed signal to noise ratio, three commonly-used tracers, the J=4->3 line of CO, the J=1->0 line of C^{18}O and the (1,1) inversion transition of NH_3, generally offer the best compromise between these competing biases, and produce estimates of the velocity dispersion that reflect the true kinematics of a molecular cloud to an accuracy of about 10% regardless of the cloud magnetic field strengths, evolutionary state, or orientations of the line of sight relative to the magnetic field.

description: The objective of this study was to delineate and measure the effects of selected economic demographic characteristics of Mississippi counties on the number and type of direct marketing of fruits and vegetables. A combination of primary data collected through a survey of county agents and secondary data from government sources were assembled to achieve the objective. Regression equations representing pick-your own marketing, farmers' markets and farm stands were estimated with the iterative three stage least squares technique. Results indicated that economic factors such as income, employment, acreage, and demographic factors (e.g., total population of county, and the size of cities and towns within county boundaries) have varied impacts on the different types of direct marketing.

description: The spin-transfer effect has been studied in magnetic tunnel junctions (PtMn/CoFe/Ru/CoFe/Al2O3/CoFe/NiFe) with dimensions down to 0.1x0.2 um2 and resistance-area product RA in the range of 0.5-10 Ohm m2 (dR/R=1-20%). Current-induced magnetization switching is observed with a critical current density of about 8e6 A/cm2. The attribution of the switching to the spin-transfer effect is supported by a current-induced dR/R value identical to the one obtained from the R versus H measurements. Furthermore, the critical switching current density has clear dependence on the applied magnetic field, consistent with what has been observed previously in the case of spin-transfer induced switching in metallic multilayer systems.

description: We report on a thorough dielectric investigation of the glass-like freezing of the orbital reorientation-dynamics, recently found for the crystalline sulpho-spinels FeCr2S4 and FeSc2S4. As the orbital reorientations are coupled to a rearrangement of the surrounding ionic lattice via the Jahn-Teller effect, the freezing of the orbital moments is revealed by a relaxational behaviour of the complex dielectric permittivity. Additional conductivity (both dc and ac) and contact contributions showing up in the spectra are taken into account by an equivalent circuit description. The orbital relaxation dynamics continuously slows down over six decades in time, before at the lowest temperatures the glass transition becomes suppressed by quantum tunnelling.

Determination of binding constants by computer simulation of affinity capillary electrophoresis
Creators: name: Fang, Ning
Publisher: name: University of British Columbia
Year: 2009

description: The aim of this work is to test and improve the mathematical models of affinity capillary electrophoresis (ACE), to implement these models by computer simulation, and to use the simulation programs to determine the medium- and high-affinity binding constants for protein-ligand interactions. The first part of this thesis presents the first mathematical model, the one-cell model, of ACE and the derivations of the equations for both 2:1 (analyte:additive) and 1:1 interactions. The steady state equations were also introduced due to their important roles in analyzing the simulated results. The second part of this thesis presents four simulation programs which were based on the one-cell model and used to simulate the ACE processes, to collect and analyze simulation data, and to estimate the binding constants for the protein-ligand interactions. In this work, we performed several series of experiments and used the simulation programs to determine the binding constants for the 2:1 interaction between flurbiprofen and transthyretin, and the binding constant for the 1:1 interaction between chlorpromazine and quaic riboflavin binding protein (qRfBP). The one-cell model is extremely fast in simulating ACE processes, but it cannot accurately describe the ACE experiments with high concentrations of analyte ([A]) and additive ([P]) or a high ratio of [A] to [P]. Thus, in the final part of this thesis, a new model and its improved implementation algorithm were proposed.

description: We present a new method employing machine learning techniques for measuring astrophysical features by correcting systematics in IRAC high precision photometry using Random Forests. The main systematic in IRAC light curve data is position changes due to unavoidable telescope motions coupled with an intrapixel response function. We aim to use the large amount of publicly available calibration data for the single pixel used for this type of work (the sweet spot pixel) to make a fast, easy to use, accurate correction to science data. This correction on calibration data has the advantage of using an independent dataset instead of using the science data on itself, which has the disadvantage of including astrophysical variations. After focusing on feature engineering and hyperparameter optimization, we show that a boosted random forest model can reduce the data such that we measure the median of ten archival eclipse observations of XO-3b to be 1459 +- 200 parts per million. This is a comparable depth to the average of those in the literature done by seven different methods, however the spread in measurements is 30-100% larger than those literature values, depending on the reduction method. We also caution others attempting similar methods to check their results with the fiducial dataset of XO-3b as we were also able to find models providing initially great scores on their internal test datasets but whose results significantly underestimated the eclipse depth of that planet.

description: Income elasticities of demand were estimated for nine aggregate food categories for a sample of Hispanic consumers. In general, the demand for food appears to be relatively inelastic with respect to income, although the situation may be quite different when more disaggregated food categories are considered. Government subsidies received by households may also impact the demand for specific food groups. Although not conclusive, the results of this study indicate that Hispanic households participating in the WIC program consume more fruits, milk and pork, and less total fats, beverages, and chicken than households not participating in the income transfer programs. The results for food stamps were less conclusive.

description: We introduce a general framework for the reconstruction of periodic multivariate functions from finitely many and possibly noisy linear measurements. The reconstruction task is formulated as a penalized convex optimization problem, taking the form of a sum between a convex data fidelity functional and a sparsity-promoting total variation based penalty involving a suitable spline-admissible regularizing operator L. In this context, we establish a periodic representer theorem, showing that the extreme-point solutions are periodic L-splines with less knots than the number of measurements. The main results are specified for the broadest classes of measurement functionals, spline-admissible operators, and convex data fidelity functionals. We exemplify our results for various regularization operators and measurement types (e.g., spatial sampling, Fourier sampling, or square-integrable functions). We also consider the reconstruction of both univariate and multivariate periodic functions.

description: In the light of recent observations in which short gamma-ray bursts are interpreted as arising from black-hole(BH), neutron-star(NS) or NS-NS mergings we would like to review our research on the evolution of compact binaries, especially those containing NS's. These were carried out with predictions for LIGO in mind, but are directly applicable to short gamma-ray bursts in the interpretation above. Most important in our review is that we show that the standard scenario for evolving NS-NS binaries always ends up with a low-mass BH (LMBH), NS binary. Bethe and Brown (1998) showed that this fate could be avoided if the two giants in the progenitor binary burned He at the same time, and that in this way the binary could avoid the common envelope evolution of the NS with red giant companion which sends the first born NS into a BH in the standard scenario. The burning of He at the same time requires, for the more massive giants such as the progenitors of the Hulse-Taylor binary NS that the two giants be within 4% of each other in ZAMS mass. Applying this criterion to all binaries results in a factor 5 of LMBH-NS binaries as compared with NS-NS binaries. Our scenario of NS-NS binaries as having been preceded by a double He-star binary is collecting observational support in terms of the nearly equal NS masses within a given close binary.

Quadrupole mass filters operated in higher stability regions
Creators: name: Chen, Wei
Publisher: name: University of British Columbia
Year: 2009

description: This thesis describes experimental and theoretical studies of the properties of a quadrupole mass filter operated in the fourth stability region (Mathieu parameters a≈0 and q≈21.3) and the sixth stability region (Mathieu parameters a≈8, q≈6). The experimental work is done with a thermal ionization quadrupole mass spectrometer. The objective is to improve the resolution of inductively coupled plasma mass spectrometers for elemental analysis. With a quadrupole operated in the fourth region, a resolution measured as full peak width at half height (R[sub ½]) of up to 13,900 with 40 eV ³⁹K⁺ ions is obtained and a resolution of several thousand at m/z 39 with ions of several keV energy is achieved. The transmission is somewhat lower than that of the second stability region for a given resolution between 1500 and 5000, but much higher than that expected from acceptance calculations. Operation in the sixth stability region gives a maximum resolution of R[sub ½]=2000 for ³⁹K⁺ ions with an axial ion energy of 20 eV, and resolution of several hundred with high energy ions (>1000 eV). Operation at the upper (M) tip usually gives relatively higher resolution and transmission than operation at the lower (S) tip for the same ion energy. Thus for ions of intermediate energy, a quadrupole operated in the sixth stability region can also be used as an independent mass filter. This region could also be used as an additional mass filter to eliminate alias ions when a quadrupole is operated in regions II or IV. This thesis also describes a theoretical calculation of the ion optical properties of a quadrupole operated near the fourth and the sixth regions. For these regions, ions experience fewer RF cycles inside the quadrupole field because relatively higher energies are required to penetrate the fringing field at the entrance of the quadrupole rods. Ions outside the stability regions can thus pass through the quadrupole. Thus the stability boundaries are considered diffuse. For the fourth stability region, a narrower peak could not be obtained with a>0 for ion energies larger than 500 eV, and split peaks were observed with a scan line operated above the tip of the region. For the sixth stability region, broader peaks are obtained with higher energy ions, and the y-stability band dominates the ion transmission. Peaks were observed when using a quadrupole operated beyond the two tips of this region.

description: Consumer behavior in the context of online food retail channels is analyzed. The research is a follow-up to an earlier study conducted in early 1998 on consumer response to online food shopping. In the 1998 study (N=243), a majority of the sample (51 percent) were "new" users of online food shopping (<6 months); 35 percent were "intermediate" users (1-6 months); and only 14 percent were "experienced" users (>6 months). In contrast, the new user segment in the follow-up study (N=412) was 29 percent; the intermediate segment was 28 percent; and the experienced group was 43 percent. Demographic profiles and shopping behaviors of respondents in the two studies are compared. Using cluster analysis, four distinct segments of online food shoppers are identified. Marketing strategy implications for online retailers and store retailers are discussed.

Rotational transport via spontaneous symmetry breaking in vibrated disk packings

description: It is shown that vibrated packings of frictional disks self-organize cooperatively onto a rotational-transport state where the long-time angular velocity $\barω_i$ of each disk $i$ is nonzero. Steady rotation is mediated by the spontaneous breaking of local reflection symmetry, arising when the cages in which disks are constrained by their neighbors acquire quenched disorder at large packing densities. Experiments and numerical simulation of this unexpected phenomenon show excellent agreement with each other, revealing two rotational phases as a function of excitation intensity, respectively the low-drive (LDR) and the moderate-drive (MDR) regimes. In the LDR, interdisk contacts are persistent and rotation happens due to frictional sliding. In the MDR, disks bounce against each other, still forming a solid phase. In the LDR, simple energy-dissipation arguments are provided, that support the observed dependence of the typical rotational velocity on excitation strength.

description: The construction of quantum computer simulators requires advanced software which can capture the most significant characteristics of the quantum behavior and quantum states of qubits in such systems. Additionally, one needs to provide valid models for the description of the interface between classical circuitry and quantum core hardware. In this study, we model electron transport in semiconductor qubits based on an advanced CMOS technology. Starting from 3D simulations, we demonstrate an order reduction and the steps necessary to obtain ordinary differential equations on probability amplitudes in a multi-particle system. We compare numerical and semi-analytical techniques concluding this paper by examining two case studies: the electron transfer through multiple quantum dots and the construction of a Hadamard gate simulated using a numerical method to solve the time-dependent Schrodinger equation and the tight-binding formalism for a time-dependent Hamiltonian.

description: A generalized skew information is defined and a generalized uncertainty relation is established with the help of a trace inequality which was recently proven by J.I.Fujii. In addition, we prove the trace inequality conjectured by S.Luo and Z.Zhang. Finally we point out that Theorem 1 in {\it S.Luo and Q.Zhang, IEEE Trans.IT, Vol.50, pp.1778-1782 (2004)} is incorrect in general, by giving a simple counter-example.

description: A central mechanism in machine learning is to identify, store, and recognize patterns. How to learn, access, and retrieve such patterns is crucial in Hopfield networks and the more recent transformer architectures. We show that the attention mechanism of transformer architectures is actually the update rule of modern Hopfield networks that can store exponentially many patterns. We exploit this high storage capacity of modern Hopfield networks to solve a challenging multiple instance learning (MIL) problem in computational biology: immune repertoire classification. Accurate and interpretable machine learning methods solving this problem could pave the way towards new vaccines and therapies, which is currently a very relevant research topic intensified by the COVID-19 crisis. Immune repertoire classification based on the vast number of immunosequences of an individual is a MIL problem with an unprecedentedly massive number of instances, two orders of magnitude larger than currently considered problems, and with an extremely low witness rate. In this work, we present our novel method DeepRC that integrates transformer-like attention, or equivalently modern Hopfield networks, into deep learning architectures for massive MIL such as immune repertoire classification. We demonstrate that DeepRC outperforms all other methods with respect to predictive performance on large-scale experiments, including simulated and real-world virus infection data, and enables the extraction of sequence motifs that are connected to a given disease class.
