description: Using the nonequilibrium Green function, we show that microwave irradiation can reverse the supercurrent flowing through a superconductor / quantum-dot / superconductor structure. In contrast with the conventional sideband effect in normal-metal / quantum-dot / normal-metal junctions, the photon-assisted structures appear near $E_{0}=\frac{n}{2}\hbar ω(n=\pm 1,\pm 2...)$, where $E_{0}$ is the resonant energy level of the quantum dot and $ω$ is the frequency of microwave field. Each photon-assisted structure is composed of a negative and a positive peak, with an abrupt jump from the negative peak to the positive peak around $E_{0}=\frac{n}{2}\hbar ω$. The microwave-induced $π$-junction transition is interpreted in the picture of photon-assisted Andreev bound states, which are formed due to multiple photon-assisted Andreev reflection between the two superconductors. Moreover, the main resonance located at $E_{0}=0$ can also be reversed with proper microwave strength and frequency.

description: У пропонованому дослідженні виконано параметризацію апарата для визначення коефіцієнтів впливу координат заданих точок на координату поточної точки інтерполянта у загальному випадку, а також розглянуто окремі випадки такого апарату і виконано їх аналіз. Існує багато різних способів інтерполяції точок [1-3]. Деякі задачі інтерполяції точок вимагають врахування впливу параметрів заданих точок на параметри точки, яку визначають. Зокрема, у багатьох задачах цей вплив пов'язано з відстанями поточної точки інтерполяції від заданих точок. Причому цей вплив має бути тим більше, чим ближче задана точка знаходитися до поточної. На точку, нескінченно близьку до заданої точки, ця задана точка повинна впливати максимально, а при нескінченно великій відстан і між заданою і поточною точкою цей вплив має дорівнювати нулю. Прикладом такої практичної задачі може бути: визначення температури в заданому місці температурного поля, яке утворено точковими джерелами нагріву [4-6] або визначення освітленості в заданій точці простору при точкових джерелах світла [7] і т.д.

description: The motion of biological micro-robots -- similar to that of swimming microorganisms such as bacteria or spermatozoa -- is governed by different physical rules than what we experience in our daily life. This is particularly due to the low-Reynolds-number condition of swimmers in micron scales. The Quadroar swimmer, with three-dimensional maneuverability, has been introduced for moving in these extreme cases: either as a bio-medical micro-robot swimming in biological fluids or a mm-scale robot performing inspection missions in highly viscous fluid reservoirs. Our previous studies address the theoretical modeling of this type of swimmer system. In this work, we present the mechatronic design, fabrication, and experimental study of a mm-scale Quadroar swimmer. We describe the design methodology and component selection of the system based on the required performance. A supervisory control scheme is presented to achieve an accurate trajectory tracking for all the actuators used in the swimmer. Finally, we have conducted experiments in silicone oil (with 5000 cP viscosity) where two primary modes of swimming - forward translation and planar reorientation - have been tested and compared with the theoretical model.

description: Наведено приклади побудови дискретних каркасів об’єктів дизайну у вигляді ваз, дискретні сітки яких утворюють певні візерунки на поверхні. Проблема створення нових естетичних форм дизайн-об’єктів є центральною у технічній естетиці. Для її вирішення необхідні глибинні теоретичні дослідження естетичних властивостей об’єктів, особливостей їх естетичного сприйняття. Для побудови дискретних каркасів поверхонь у роботі запропоновано узагальнений статико-геометричний метод. Цей метод, як один із методів дискретного геометричного моделювання, активно використовують при проектуванні архітектурних або дизайн-об’єктів у випадках, коли за природою утворення поверхні неможливо отримати її аналітичного рівняння. За допомогою цього методу можна утворювати дискретні каркаси поверхонь у вигляді сіток із довільним кроком. У роботі продемонстровано можливість створення нових поверхонь-образів за рахунок використання конструктивного розподілу зовнішнього формоутворюючого навантаження на вузли дискретної сітки, яку нанесено на цю поверхню. Тобто, розподіл зовнішнього формоутворюючого навантаження можна задавати конструктивно у вигляді деякої аналітично заданої поверхні, якщо на цю поверхню нанести дискретну сітку, топологічні характеристики якої мають бути ідентичними відповідним характеристикам сітки, що буде наноситись на поверхню-образ. Це допомагає прогнозувати різні естетичні характеристики образу та переносити на модельовані поверхні властивості обраних аналітично заданих поверхонь-прообразів.

description: We study the variable-length ensemble of self-avoiding walks on the complete graph. We obtain the leading order asymptotics of the mean and variance of the walk length, as the number of vertices goes to infinity. Central limit theorems for the walk length are also established, in various regimes of fugacity. Particular attention is given to sequences of fugacities that converge to the critical point, and the effect of the rate of convergence of these fugacity sequences on the limiting walk length is studied in detail. Physically, this corresponds to studying the asymptotic walk length on a general class of pseudocritical points.

description: Niger is one of the poorest countries in the world. The most recent UNDP1 report classifies Niger as the last country in terms of human development index. Although more than 80 percent of the economically active population is involved in farming, the agriculture sector generates only around 40 percent of the gross domestic product. Since farm production is heavily dependent on rainfall, frequent extreme weather events may have a severe impact on agricultural output and household income. In this light, this study examines the potential impact of extreme weather events such as prolonged drought and flooding and other selected climate variables on yield of the three major crops in this country: millet, sorghum, and dry bean. Using data from a nationally representative survey conducted in 2014, the estimation results show that drought has a significant negative effect on sorghum and dry bean yield. However, flood have no impact on any of the three crop yields. An increase in temperature affects negatively all three crops yield threatening therefore farm income, and household food security. These results are likely to be further amplified by rising global warming and climate change.

description: The interplay of Umklapp scattering from a periodic potential and other scattering processes determine the conductivity of (quasi) one-dimensional metals. We show that the transport at finite temperature is qualitatively and quantitatively strongly influenced by a number of approximate conservation laws. Typically, not the strongest but the second strongest scattering mechanism determines the dc-conductivity. We discuss the optical conductivity both of strongly anisotropic, quasi one-dimensional Fermi liquids and of Luttinger liquids.

Coulomb Blockade Peak Spacing Distribution: The Interplay of Temperature and Spin

Publisher: name: arXiv
Year: 2001
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We calculate the Coulomb Blockade peak spacing distribution at finite temperature using the recently introduced ``universal Hamiltonian'' to describe the e-e interactions. We show that the temperature effect is important even at kT~0.1Δ(Δis the single-particle mean level spacing). This sensitivity arises because: (1) exchange reduces the minimum energy of excitation from the ground state and (2) the entropic contribution depends on the change of the spin of the quantum dot. Including the leading corrections to the universal Hamiltonian yields results in quantitative agreement with the experiments. Surprisingly, temperature appears to be the most important effect.

description: The emerging progress of esports lacks the approaches for ensuring high-quality analytics and training in professional and amateur esports teams. In this paper, we demonstrated the application of Artificial Intelligence (AI) and Machine Learning (ML) approach in the esports domain, particularly in simu?lated racing. To achieve this, we gathered a variety of feature-rich telemetry data from several web sources that was captured through MoTec telemetry software and the ACC simulated racing game. We performed a number of analyses using ML algorithms to classify the laps into the performance levels, evaluating driving behaviors along these performance levels, and finally defined a prediction model highlighting the channels/features that have significant impact on the driver performance. To identify the optimal feature set, three feature selection algorithms, i.e., the Support Vector Machine (SVM), Extreme Gradient Boosting (XGBoost) and Random Forest (RF) have been applied where out of 84 features, a subset of 10 features has been selected as the best feature subset. For the classification, XGBoost outperformed RF and SVM with the highest accuracy score among the other evaluated models. The study highlights the promising use of AI to categorize sim racers according to their technical-tactical behaviour, enhancing sim racing knowledge and know how.

description: In this study, we utilize a panel of subnational district-level yields for corn matched to weather data that is spatially interpolated from observed weather station data to identify whether warming impacts exhibit spatial heterogeneities for both the mean and variance of corn yields in Ghana. Results are expected to demonstrate that there exist pertinent regional differences in climate change impacts. Some of these differences will likely be attributed to the localized change in climate, while others will likely be associated with particular agronomic characteristics (e.g. soil type) that can partially mitigate (or exacerbate) the effects of warming temperatures. Climate change impacts on agriculture have been widely researched in recent years. In Sub-Saharan Africa (SSA), many of these studies have focused on spatially aggregate impacts at the country or higher level, and typically do not discuss the heterogeneity of within-region impacts. Thus, there is a growing interest in more localized climate change impacts that could help inform regional adaptation within a country. Globally, climate change is estimated to have adverse effects on crop yields. With agriculture being the mainstay of many economies in SSA, it is expected that these economies are especially vulnerable to climate change. Ghana is one of the fastest growing economies in SSA (World Bank Report, 2015). Over 20 percent of gross domestic product (GDP) and two-thirds of agricultural GDP in Ghana are staple crops and livestock production (OECD Report, 2010). It is therefore important to quantify the effect of climate change on crop yields in Ghana. In addition, we explore the extent to which impacts might vary across different agronomic regions of the country as this can aid producers and policy makers in defining potential adaptation mechanisms.

description: We study the dual equivalence between the nonlinear generalization of the self-dual ($NSD_{B\wedge F}$) and the topologically massive $B\wedge F$ models with particular emphasis on the nonlinear electrodynamics proposed by Born and Infeld. This is done through a dynamical gauge embedding of the nonlinear self-dual model yielding to a gauge invariant and dynamically equivalent theory. We clearly show that nonpolinomial $NSD_{B\wedge F}$ models can be mapped, through a properly defined duality transformation, into $TM_{B\wedge F}$ actions. The general result obtained is then particularized for a number of examples, including the Born-Infeld-BF (BIBF) model that has experienced a revival in the recent literature.

description: Forest resources are the most prominent source of fuelwood in Nepal i.e., around 70% of residential energy comes from this sector (MOF, 2015). The survival of rural households in Nepal is directly linked to forest resources as many of these households are subsistence users of forest products (FAO, 2009). Women were found to be the predominant labor force involved in fuelwood collection in our study area. The sampled household in our study were found to be reliant in fuelwood and other energy sources for energy. Private tree plantation for fodder and fuelwood purposes can act as substitute to fuelwood collected from community forest areas.

description: The Trans-Pacific Partnership (TPP) is a proposed regional free trade agreement (FTA) among 12 countries: Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, the United States, and Vietnam. The TPP by eliminating more than 18,000 taxes and other trade barriers on American products across the 11 other countries is expected make it easier for American entrepreneurs, farmers, and small business owners to sell Made-In-America products abroad. This paper attempts to examine the factors that affects trade creation and trade diversion between the US and TPP countries using the gravity model by applying both panel pooled data from 1991 to 2015 to four gravity equations (agricultural related products, bulk agricultural products, consumer oriented agricultural products, and intermediate agricultural products) in each case. The factors include traditional trade variables GDP of US (exporting country), GDP of importing countries, FTA’s, border, language, real exchange rate, arable land and population for U.S. Three models (One-way random effect, the two-way random effect and pooled) were applied to each of the four products. In all, the pooled model showed the highest predictive power and with consistent parameters. Similarly, considering the specific products, consumer oriented and intermediate products are the most sensitive to these factors while bulk agricultural products are the least.

molecular knots

description: Abstract: Recent theoretical studies have demonstrated that the behaviour of molecular knots is a sensitive indicator of polymer structure. Here, we use knots to verify the ability of two state-of-the-art algorithms—configuration assembly and hierarchical backmapping—to equilibrate high-molecular-weight (MW) polymer melts. Specifically, we consider melts with MWs equivalent to several tens of entanglement lengths and various chain flexibilities, generated with both strategies. We compare their unknotting probability, unknotting length, knot spectra, and knot length distributions. The excellent agreement between the two independent methods with respect to knotting properties provides an additional strong validation of their ability to equilibrate dense high-MW polymeric liquids. By demonstrating this consistency of knotting behaviour, our study opens the way for studying topological properties of polymer melts beyond time and length scales accessible to brute-force molecular dynamics simulations.

Non-Abelian linear Boltzmann equation and quantum correction to Kramers and Smoluchowski equation

description: A quantum linear Boltzmann equation is proposed, constructed in terms of the operator-valued dynamic structure factor of the macroscopic system the test particle is interacting with. Due to this operator structure it is a non-Abelian linear Boltzmann equation and when expressed through the Wigner function it allows for a direct comparison with the classical one. Considering a Brownian particle the corresponding Fokker-Planck equation is obtained in a most direct way taking the limit of small energy and momentum transfer. A typically quantum correction to the Kramers equation thus appears, describing diffusion in position and further implying a correction to Einstein's diffusion coefficient in the high temperature and friction limit in which Smoluchowski equation emerges.

Особливо актуальним є виявлення конфліктів параметрів і правил, які пов’язані з реформуванням законодавства в частині, що стосується технічного регулювання галузі. Автоматичне виявлення невизначеності суттєво спрощує розробку проектної документації та проведення експертних оцінок на стадіях будівництва і експлуатації унікальних об’єктів. Проте реалізація подібних алгоритмів надає змогу суттєво покращити роботу інших організаційно-технічних систем за рахунок підвищення швидкості і надійності роботи підсистеми документообігу в умовах трансформацій. Наукова новизна результатів дослідження полягає у впровадженні моделей нечіткої математики в процеси оброблення текстової інформації. Результати роботи показано на прикладі визначення параметра технічного регулювання за наявності надлишкової інформації.

Effects of Imperfect Information on 2014 Farm Bill Program Enrollment

description: ABSTRACT BACKGROUND AND PURPOSE: The 2014 Farm Bill required Kansas wheat producers to make a series of enrollment decisions that were both complicated and based on incomplete information. With this bill, producers were required to complete a one-time enrollment in one of three programs (ARC-CO, PLC, or ARC-IC) to serve as a safety net for poor crop prices and/or yields over the subsequent five-year life of the legislation. Analyzing the effects of incomplete information on producers’ decisions provides an opportunity to identify challenges associated with program selection under the 2014 Farm Bill and suggest changes for future farm support legislation. METHODS: Kansas county-level enrollment data for wheat base acres obtained from USDA-FSA are used to model aggregate producer sign-up decisions as a function of estimated 2014 payments, county-level yield variability, prior farm program enrollment, and extension programming efforts at the county and state level. This OLS model is subsequently replicated using individual producer data from surveys conducted during fifteen extension meetings held across Kansas. The model based on individual data is a regression of stated preferences for the three programs as a function of farm size, farmer demographics, risk preferences, and knowledge of the Farm Bill. RESULTS: Comparisons of model results from the aggregated enrollment data and the individual survey data offer greater insights into the factors affecting producer decisions. Specifically, aggregate enrollment decisions are primarily explained by expected payments for the first year of the program. For counties with a positive expected payment for 2014 under the ARC-CO program, enrollment in that program was higher. However, when the regression is repeated using individual data, other factors affect the enrollment decision such as the number of years a producer has been farming, the size of the farm, their membership in commodity associations, and their preferences for risk protection. CONCLUSIONS : The 2014 Farm Bill required producers to select participation in a single support program for the five-year life of the legislation. This decision had to be made without knowing exactly how crop prices and yields would behave in the future. It is important to understand how producers made their decisions based on incomplete information to inform future legislative efforts for an effective farm safety net. This research expands that understanding by analyzing both aggregate and individual data to determine the factors that influence program choice.

description: Radio Cherenkov radiation is arguably the most efficient mechanism for detecting showers from ultra-high energy particles of 1 PeV and above. Showers occuring in Antarctic ice should be detectable at distances up to 1 km. We report on electromagnetic shower development in ice using a GEANT Monte Carlo simulation. We have studied energy deposition by shower particles and determined shower parameters for several different media, finding agreement with published results where available. We also report on radio pulse emission from the charged particles in the shower, focusing on coherent emission at the Cherenkov angle. Previous work has focused on frequencies in the 100 MHz to 1 GHz range. Surprisingly, we find that the coherence regime extends up to tens of Ghz. This may have substantial impact on future radio-based neutrino detection experiments as well as any test beam experiment which seeks to measure coherent Cherenkov radiation from an electromagnetic shower. Our study is particularly important for the RICE experiment at the South Pole.

Efficient index handling of multidimensional periodic boundary conditions

description: An efficient method is described to handle mesh indexes in multidimensional problems like numerical integration of partial differential equations, lattice model simulations, and determination of atomic neighbor lists. By creating an extended mesh, beyond the periodic unit cell, the stride in memory between equivalent pairs of mesh points is independent of their position within the cell. This allows to contract the mesh indexes of all dimensions into a single index, avoiding modulo and other implicit index operations.

Log-Expansions from Combinatorial Dyson-Schwinger Equations

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We give a precise connection between combinatorial Dyson-Schwinger equations and log-expansions for Green's functions in quantum field theory. The latter are triangular power series in the coupling constant $α$ and a logarithmic energy scale $L$ --- a reordering of terms as $G(α,L) = 1 \pm \sum_{j \geq 0} α^j H_j(αL)$ is the corresponding log-expansion. In a first part of this paper, we derive the leading-log order $H_0$ and the next-to$^{(j)}$-leading log orders $H_j$ from the Callan-Symanzik equation. In particular, $H_j$ only depends on the $(j+1)$-loop $β$-function and anomalous dimensions. For the photon propagator Green's function in quantum electrodynamics (and in a toy model, where all Feynman graphs with vertex sub-divergences are neglected), our formulas reproduce the known expressions for the next-to-next-to-leading log approximation in the literature. In a second part of this work, we review the connection between the Callan-Symanzik equation and Dyson-Schwinger equations, i.e. fixed-point relations for the Green's functions. Combining the arguments, our work provides a derivation of the log-expansions for Green's functions from the corresponding Dyson-Schwinger equations.
