description: The plateau phenomenon, wherein the loss value stops decreasing during the process of learning, has been reported by various researchers. The phenomenon is actively inspected in the 1990s and found to be due to the fundamental hierarchical structure of neural network models. Then the phenomenon has been thought as inevitable. However, the phenomenon seldom occurs in the context of recent deep learning. There is a gap between theory and reality. In this paper, using statistical mechanical formulation, we clarified the relationship between the plateau phenomenon and the statistical property of the data learned. It is shown that the data whose covariance has small and dispersed eigenvalues tend to make the plateau phenomenon inconspicuous.

description: Deep pretrained transformer networks are effective at various ranking tasks, such as question answering and ad-hoc document ranking. However, their computational expenses deem them cost-prohibitive in practice. Our proposed approach, called PreTTR (Precomputing Transformer Term Representations), considerably reduces the query-time latency of deep transformer networks (up to a 42x speedup on web document ranking) making these networks more practical to use in a real-time ranking scenario. Specifically, we precompute part of the document term representations at indexing time (without a query), and merge them with the query representation at query time to compute the final ranking score. Due to the large size of the token representations, we also propose an effective approach to reduce the storage requirement by training a compression layer to match attention scores. Our compression technique reduces the storage required up to 95% and it can be applied without a substantial degradation in ranking performance.

description: We complete our earlier (Phys. Rev. B, {\bf 66}, 134435 (2002)) study of the electronic structure, exchange interactions and Curie temperature in (GaMn)As and extend the study to two other diluted magnetic semiconductors (GaCr)As and (GaFe)As. Four concentrations of the 3d impurities are studied: 25%, 12.5%, 6.25%, 3.125%. (GaCr)As and (GaMn)As are found to possess a number of similar features. Both are semi-metallic and ferromagnetic, with similar properties of the interatomic exchange interactions and the same scale of the Curie temperature. In both systems the presence of the charge carriers is crucial for establishing the ferromagnetic order. An important difference between two systems is in the character of the dependence on the variation of the number of carriers. The ferromagnetism in (GaMn)As is found to be very sensitive to the presence of the donor defects, like As$_{\rm Ga}$ antisites. On the other hand, the Curie temperature of (GaCr)As depends rather weakly on the presence of this type of defects but decreases strongly with decreasing number of electrons. We find the exchange interactions between 3d atoms that make a major contribution into the ferromagnetism of (GaCr)As and (GaMn)As and propose an exchange path responsible for these interactions. The properties of (GaFe)As are found to differ crucially from the properties of (GaCr)As and (GaMn)As. (GaFe)As does not show a trend to ferromagnetism and is not half-metallic that makes this system unsuitable for the use in spintronic semiconductor devices.

description: A new 4-aminomethylbenzoic acid-functionalized Fe3O4 magnetic nanoparticles as a hybrid heterogeneous catalyst was synthesised and characterized by FT-IR, XRD, TGA, TEM, SEM and VSM techniques. The catalytic activity of this nanocatalyst was probed through one-pot synthesis of 2-amino-4H-chromene derivatives from three component reactions of various aldehydes, malononitrile and dimedone. The chemically and thermally stable catalyst was easily recovered using an external magnet and reused for at least five successive runs without significant loss of its activity. The simplicity of the method, high yields of the products, mild reaction conditions and low reaction times are the other advantages of this procedure.

description: This paper is a review and analysis of current mentoring practices in public school systems. More specifically, our research centres around comparing and contrasting existing mentorship models and then analyzing how these may or may not relate to the current practices of a school district in the Lower Mainland of British Columbia. The research involves a systematic literature review and interviews with educational experts who hold district leadership positions. These two components identified a number of overarching themes of mentoring programs: structure and format of programs, collaboration and reciprocity of relationships, support for teachers, mandated and voluntary enrolment, and resource allocation.

description: In transition of one economy, the state has catalyst role, as through physical and institutional infrastructure, as well as through public sector, to eliminate market obstacles, supports development, technological progress and education, especially in following activities: energetic, agriculture and telecommunications. Key fault in transition is opinion that drastic changes should be made at once, big institutional changes have to be done as soon as possible, and reality should be put into the frame of on that way artificially created institutions. In transitional countries, foreign direct investments have financial dimension, but also they are significant for competitiveness and innovations stimulation, initiation of new technologies, improvement of employees’ skills and knowledge, primarily managers. Investors strive to find: natural resources, market, strategic property and to increase their own efficiency and inclusion into the global economic courses. Family husbandry represents one of the basic segments of economic and social activities in agriculture, as one of the important economic activities for the country in the transition process. Its crucial characteristic, which makes it different from other subjects, is dual content of its function. Within are concentrated, both family and husbandry, i.e. in it are realized both, productive and consumptive activities. In countries with high-developed agriculture, long time ago, had been observed a need for following and analyzing of the family husbandries business results. However, in our country is still not determined concept and obligation for accounting conduction on the husbandry. This paper represents an effort to analyze necessity of book keeping evidence conduction, as a base for improvement of family husbandry and possibility for better agriculture's competitiveness.

description: A test particle orbit around an eccentric binary has two stationary states in which there is no nodal precession: coplanar and polar. Nodal precession of a misaligned test particle orbit centres on one of these stationary states. A low mass circumbinary disc undergoes the same precession and moves towards one of these states through dissipation within the disc. For a massive particle orbit, the stationary polar alignment occurs at an inclination less than $90^{\circ}$, this is the prograde-polar stationary inclination. A sufficiently high angular momentum particle has an additional higher inclination stationary state, the retrograde-polar stationary inclination. Misaligned particle orbits close to the retrograde-polar stationary inclination are not nested like the orbits close to the other stationary points. We investigate the evolution of a gas disc that begins close to the retrograde-polar stationary inclination. With hydrodynamical disc simulations, we find that the disc moves through the unnested crescent shape precession orbits and eventually moves towards the prograde-polar stationary inclination thus increasing the parameter space over which circumbinary discs move towards polar alignment. If protoplanetary discs form with an isotropic orientation relative to the binary orbit, then polar discs may be more common than coplanar discs around eccentric binaries, even for massive discs. This has implications for the alignment of circumbinary planets.

description: The position of a country within modern international division of work is determined on the basis of utilisation of the latest achievements of science and technology at its economy. This is the time when scientific-technological development, more than ever, becomes the paradigm of reputation and prestige of some socio-economic community. The essence of technological progress is optimal use of the production factor. Competitivness of a company and a country, as a whole, can be attained only in this way. In order to obtain a corrersponding basis for scientific technological progress, there have been provided adequate measures for improvement of scientific research basis in our country. On the basis of experience at utilisation of programmes for financing of innovation processes at OECD countries, utilisation of the most adequate instruments in Serbia is recommended and this is: grants for early stage of commertialisation and entrepreneurship capital for later stage. The possibilities for adjusting of these instruments are different at conditions characteristic for many countries including the countries of our region.

This method is shown to be relevant to the calculation of the critical temperature $T_c$ and the magnetic eigen-exponent $y_h$ on such structures. On the other hand, scaling corrections hinder the calculation of the temperature eigen-exponent $y_t$. At last, the results are shown to be consistent with a finite size scaling analysis.

description: Mitochondrial dysfunction is involved in Alzheimer’s disease (AD) pathogenesis. Mitochondria have their own genetic material; however, most of their proteins (∼99%) are synthesized as precursors on cytosolic ribosomes, and then imported into the mitochondria. Therefore, exploring proteome changes in these organelles can yield valuable information and shed light on the molecular mechanisms underlying mitochondrial dysfunction in AD. Here, we review AD-associated mitochondrial changes including the effects of amyloid beta and tau protein accumulation on the mitochondrial proteome. We also discuss the relationship of ApoE genetic polymorphism with mitochondrial changes, and present a meta-analysis of various differentially expressed proteins in the mitochondria in AD. Area covered: Proteomics studies and their contribution to our understanding of mitochondrial dysfunction in AD pathogenesis. Expert opinion: Proteomics has proven to be an efficient tool to uncover various aspects of this complex organelle, which will broaden our understanding of mitochondrial dysfunction in AD. Evidently, mitochondrial dysfunction is an early biochemical event that might play a central role in driving AD pathogenesis.

description: We report the magnetic properties, electrical resistivity, and Vickers microhardness of as-cast and annealed high-entropy alloys (HEAs) FeCoNiPd and FeCoNiPt with the face-centered cubic structure. The heat treatment at 800 $^{\circ}$C does not largely affect the physical properties in each HEA. The values of the Curie temperature and the saturation moment at 50 K are 955 K and 1.458 $μ_\mathrm{B}$/f.u. for the annealed FeCoNiPd, and 851 K and 1.456 $μ_\mathrm{B}$/f.u. for the annealed FeCoNiPt, respectively. Each HEA is a soft ferromagnet and shows metallic resistivity. The electronic structure calculations of both HEAs support the ferromagnetic ground states. The comparisons between experimental and theoretical values are made for the Curie temperature, the saturation moment, and the residual resistivity. The Vickers microhardness of annealed FeCoNiPd and FeCoNiPt are both 188 HV. The hardness vs. valence electron count (VEC) per atom plot of these HEAs does not largely deviate from an expected universal relation forming a broad peak at VEC$\sim$6.8. This study would give some hints on designing a soft ferromagnetic HEA with high hardness.

description: This work shows that bulk ionic liquids (ILs) and their water solution can be conveniently investigated by synchrotron-based UV resonance Raman (UVRR) spectroscopy. The main advantages of this technique for the investigation of the local structure and intermolecular interactions in imidazolium-based ILs are presented and discussed. The unique tunability of synchrotron source allows one to selectively enhance in the Raman spectra the vibrational signals arising from the imidazolium ring. Such signals showed good sensitivity to the modifications induced in the local structure of ILs by i) the change of anion and ii) the progressively longer alkyl chain substitution on the imidazolium ring. Moreover, some UVRR signals are specifically informative on the effect induced by addition of water on the strength of cation-anion H-bonds in IL-water solutions. All of these results corroborate the potentiality of UVRR to retrieve information on the intermolecular interactions in IL-water solutions, besides the counterpart obtained by employing on these systems the spontaneous Raman scattering technique.

description: Abiocompatible method for synthesizing of highly disperses gold nanoparticles using Ferulago Angulata leaf extract has been developed. It has been shown that leaf extract acts as reducing and coating agent. Various spectroscopic and electron microscopic techniques were employed for the structural characterization of the prepared nanoparticles. The biosynthesized particles were identified as elemental gold with spherical morphology, narrow size distribution (ranged 9.2–17.5 nm) with high stability. Also, the effect of initial ratio of precursors, temperature and time of reaction on the size and morphology of the nanoparticles was studied in more detail. It was observed that varying these parameters provides an accessible remote control on the size and morphology of nanoparticles. The uniqueness of this procedure lies in its cleanliness using no extra surfactant, reducing agent or any capping agent.

The fragmentation dynamics of the dication is unraveled by the use of advanced ion and electron spectroscopy giving access to the dissociation channels as well as their energetics. To get insight into the fragmentation dynamics, we use a theoretical approach combining potential energy surface determination, statistical fragmentation methods and molecular dynamics simulations. We demonstrate that the dissociation dynamics of adamantane dications takes place in a two-step process: barrierless cage opening followed by Coulomb repulsion-driven fragmentation.

description: We present an analysis of the distribution of 77 supernovae (SNe) Ia relative to spiral arms of their Sab-Scd host galaxies, using our original measurements of the SN distances from the nearby arms, and study their light curve decline rates ($Δm_{15}$). For the galaxies with prominent spiral arms, we show that the $Δm_{15}$ values of SNe Ia, which are located on the arms, are typically smaller (slower declining) than those of interarm SNe Ia (faster declining). We demonstrate that the SN Ia distances from the spiral arms and their galactocentric radii are correlated: before and after the average corotation radius, SNe Ia are located near the inner and outer edges (shock fronts) of spiral arms, respectively. For the first time, we find a significant correlation between the $Δm_{15}$ values and SN distances from the shock fronts of the arms (progenitor birthplace), which is explained in the frameworks of sub-Chandrasekhar-mass white dwarf explosion models and density wave theory, where, respectively, the $Δm_{15}$ parameter and SN distance from the shock front are appropriate progenitor population age (lifetime) indicators.

description: The properties of hybrid stars formed by hadronic and quark matter in beta-equilibrium at fixed entropies are described by appropriate equations of state (EOS) in the framework of relativistic mean-field theory. In this work we include the possibility of neutrino trapped EOS and compare the star properties with the ones obtained after deleptonization, when neutrinos have already diffused out. We use the nonlinear Walecka model for the hadron matter with two different sets for the hyperon couplings and the MIT Bag and the Nambu-Jona-Lasinio models for the quark matter. The phase transition to a deconfined quark phase is investigated. Depending on the model and the parameter set used, the mixed phase may or may not exist in the EOS at high densities. The star properties are calculated for each equation of state. The maximum mass stellar configurations obtained within the NJL have larger masses than the ones obtained within the Bag model. The Bag model predicts a mixed phase in the interior of the most massive stable stars while, depending on the hyperon couplings, the NJL model predicts a mixed phase or pure quark matter. Comparing with neutrino free stars, the maximum allowed baryonic masses for protoneutron stars are $\sim 0.4 M_\odot$ larger for the Bag model and $\sim 0.1 M_\odot$ larger for the NJL model when neutrino trapping is imposed.

description: In the present paper we provide the closed form of the path-like solutions for the logistic and $θ$-logistic stochastic differential equations, along with the exact expressions of both their probability density functions and their moments. We simulate in addition a few typical sample trajectories, and we provide a few examples of numerical computation of the said closed formulas at different noise intensities: this shows in particular that an increasing randomness - while making the process more unpredictable - asymptotically tends to suppress in average the logistic growth. These main results are preceded by a discussion of the noiseless, deterministic versions of these models: a prologue which turns out to be instrumental - on the basis of a few simplified but functional hypotheses - to frame the logistic and $θ$-logistic equations in a unified context, within which also the Gompertz model emerges from an anomalous scaling.

description: We derive annual skymaps of the proton temperature in the inner heliosheath (IHS), and track their temporal evolution over the years from 2009 to 2016 of Interstellar Boundary Explorer observations. Other associated thermodynamic parameters also determined are the density, kappa, that is, the parameter that characterizes kappa distributions, temperature rate, polytropic index, and entropy. We exploit the theory of kappa distributions and their connection with polytropes, to (i) express a new polytropic quantity Π that remains invariant along streamlines where temperature and density may vary, (ii) parameterize the proton flux in terms of the Π invariant and kappa, and (iii) derive the temperature and density, respectively, from the slope and intercept of the linear relationship between kappa and logarithm of Π. We find the following thermodynamic characteristics: (1) Temperature sky-maps and histograms shifted to their lowest values in 2012 and their highest in 2015; (2) Temperature negatively correlated with density, reflecting the subisothermal polytropic behavior; (3) Temperature positively correlated with kappa, revealing characteristics of the mechanism responsible for generating kappa distributions; (4) Processes in IHS are sub-isothermal tending toward isobaric, consistent with previously published results; (5) Linear relationship between kappa and polytropic indices, revealing characteristics of the particle potential energy; and (6) Entropy positively correlated with polytropic index, aligned with the underlying theory that entropy increases towards the isothermal state where the kappa distribution reduces to the Maxwell Boltzmann description.

A systematic review of the literature examining choice programs and issues of equity within public education

description: The aim of this systematic literature review is to explore issues of equity surrounding choice programs in public education. We define choice program as an optional program offered in a public education system that emphasizes a particular language, culture, religion or subject matter, or uses a particular teaching philosophy. Twenty-seven articles met these criteria and were coded for themes, methodology, and location. Several dominant themes emerged relating to inequities of choice in public education: the importance of families’ socioeconomic status, geospatial concerns, issues of access to information, and parent rationale for choosing. Segregation and stratification of student populations due to choice programs were also identified as issues of equity related to educational choice. This review also identifies gaps within the literature and makes recommendations for future research and practice. Finally, this study applies these findings to the local context of Vancouver, BC, Canada, in examining the admissions process for one choice program in the district, a high school arts program (Byng Arts Mini School).

description: An interesting sequence of oxidation/Michael addition/oxidation/spirocyclization is observed in the electrolysis of caffeic acid esters in the presence of barbituric acid derivatives leading to the synthesis of a series of novel spirocycles. In an experimentally simple and clean procedure, the electrolyses proceed via a domino of electrochemical (E) and chemical (C) events with employing electrons as the only reagents in aqueous solution without introducing any catalyst or oxidant. From mechanistic point of view, a new type of domino mechanism (ECECi, Ci = spirocyclization) is proven with a unique Ci phenomenon at final step. Also, in light of experimental and theoretical NMR investigations, highly chemo and regioselectivities have been detected in these synthetic electrolyses.

On the conversion efficiency of ultracold fermionic atoms to bosonic molecules via Feshbach resonances

description: We explain why the experimental efficiency observed in the conversion of ultracold Fermi gases of $^{40}$K and $^{6}$Li atoms into diatomic Bose gases is limited to 0.5 when the Feshbach resonance sweep rate is sufficiently slow to pass adiabatically through the Landau Zener transition but faster than ``the collision rate'' in the gas, and increases beyond 0.5 when it is slower. The 0.5 efficiency limit is due to the preparation of a statistical mixture of two spin-states, required to enable s-wave scattering. By constructing the many-body state of the system we show that this preparation yields a mixture of even and odd parity pair-states, where only even parity can produce molecules. The odd parity spin-symmetric states must decorrelate before the constituent atoms can further Feshbach scatter thereby increasing the conversion efficiency; ``the collision rate'' is the pair decorrelation rate.

description: Mitochondrial dysfunction is involved in Alzheimer’s disease (AD) pathogenesis. Mitochondria have their own genetic material; however, most of their proteins (∼99%) are synthesized as precursors on cytosolic ribosomes, and then imported into the mitochondria. Therefore, exploring proteome changes in these organelles can yield valuable information and shed light on the molecular mechanisms underlying mitochondrial dysfunction in AD. Here we review AD associated mitochondrial changes including the effects of amyloid beta and tau protein accumulation on the mitochondrial proteome. We also discuss the relationship of ApoE genetic polymorphism with mitochondrial changes, and present a meta-analysis of various differentially expressed proteins in the mitochondria in AD. Proteomics studies and their contribution to our understanding of mitochondrial dysfunction in AD pathogenesis. Proteomics has proved to be an efficient tool to uncover various aspects of this complex organelle, which will broaden our understanding of mitochondrial dysfunction in AD. Evidently, mitochondrial dysfunction is an early biochemical event that might play a central role in driving AD pathogenesis.
Beurling integers with RH and large oscillation

description: We construct a Beurling generalized number system satisfying the Riemann hypothesis and whose integer counting function displays extremal oscillation in the following sense. The prime counting function of this number system satisfies $π(x)= \operatorname*{Li} (x)+ O(\sqrt{x})$, while its integer counting function satisfies the oscillation estimate $N(x) = ρx + Ω_{\pm}\bigl(x\exp(-c\sqrt{\log x\log\log x})\bigr)$ for some $c>0$, where $ρ>0$ is its asymptotic density. The construction is inspired by a classical example of H. Bohr for optimality of the convexity bound for Dirichlet series, and combines saddle-point analysis with the Diamond-Montgomery-Vorhauer probabilistic method via random prime number system approximations.

description: The relative increase in expenditure on food away from home at the expense of the at home market has been well documented. However, little work has been done on the differential impact of this shift on agricultural producers, processors and marketers in different locations and faced with different marketing institutions. This paper reports on the changing impact of the away from home phenomenon on major commodity groups, processed products and institutional sales. It appears that the manner in which the away from home market has evolved has had significant impact on many commodities, products and their respective producers and processors.

description: Fusion experiments rely heavily on the measurement of the line-integrated electron density by interferometry for density feed-back control. In recent years the discharge length has increased dramatically and is continuing to rise, resulting in environmentally induced phase drifts to become an increasingly worrisome subject, since they falsify the interferometer's measurement of the density. Especially in larger Tokamaks the loss of density control due to uncontrolled changes in the optical path length can have a disastrous outcome. The control of environmental parameters in large diagnostic/experimental halls is costly and sometimes infeasible and in some cases cannot be retro-fitted to an existing machine. In this report we present a very cheap (ca. 100 EUR), easily retro-fitted, real-time capable phase compensation scheme for interferometers measuring dispersive media over long time scales. The method is not limited to fusion, but can be applied to any continuously measuring interferometer measuring a dispersive medium. It has been successfully applied to the Wendelstein 7-X density feed-back interferometer.

description: Expected income-variance (E,V) frontiers in crop production are derived using total and random (variate difference) variance. The results show that the farm organization is influenced by the variance measure used. The authors argue that random variance is a better measure of risk; consequently random E,V frontiers provide better estimates of risk-income tradeoffs.
