description: We develop a dynamic description of an effective Dirac theory in metamaterials, in which the wavefunction is modeled by the corresponding electric and magnetic field in the metamaterial. This electro-magnetic field can be probed in the experimental setup, which means that the wavefunction of the effective theory is directly accessible by measurement. Our model is based on a plane wave expansion, which ravels the identification of Dirac spinors with single-frequency excitations of the electro-magnetic field in the metamaterial. The characteristic Zitterbewegung is shown to emerge in simulations of the effective theory and we verify this signature with an analytic solution.

description: Deep learning can accurately represent sub-grid-scale convective processes in climate models, learning from high resolution simulations. However, deep learning methods usually lack interpretability due to large internal dimensionality, resulting in reduced trustworthiness in these methods. Here, we use Variational Encoder Decoder structures (VED), a non-linear dimensionality reduction technique, to learn and understand convective processes in an aquaplanet superparameterized climate model simulation, where deep convective processes are simulated explicitly. We show that similar to previous deep learning studies based on feed-forward neural nets, the VED is capable of learning and accurately reproducing convective processes. In contrast to past work, we show this can be achieved by compressing the original information into only five latent nodes. As a result, the VED can be used to understand convective processes and delineate modes of convection through the exploration of its latent dimensions. A close investigation of the latent space enables the identification of different convective regimes: a) stable conditions are clearly distinguished from deep convection with low outgoing longwave radiation and strong precipitation; b) high optically thin cirrus-like clouds are separated from low optically thick cumulus clouds; and c) shallow convective processes are associated with large-scale moisture content and surface diabatic heating. Our results demonstrate that VEDs can accurately represent convective processes in climate models, while enabling interpretability and better understanding of sub-grid-scale physical processes, paving the way to increasingly interpretable machine learning parameterizations with promising generative properties

description: Xanthomonas translucens pv. undulosa (Xtu) is a proteobacteria which causes bacterial leaf streak (BLS) or bacterial chaff disease in wheat and barley. The constant competition for zinc (Zn) metal nutrients contributes significantly in plant–pathogen interactions. In this study, we have employed a systematic in silico approach to study the Zn-binding proteins of Xtu. From the whole proteome of Xtu, we have identified ̴approximately 7.9% of proteins having Zn-binding sequence and structural motifs. Further, 115 proteins were found homologous to plant–pathogen interaction database. Among these 115 proteins, 11 were predicted as putative secretory proteins. The functional diversity in Zn-binding proteins was revealed by functional domain, gene ontology and subcellular localization analysis. The roles of Zn-binding proteins were found to be varied in the range from metabolism, proteolysis, protein biosynthesis, transport, cell signalling, protein folding, transcription regulation, DNA repair, response to oxidative stress, RNA processing, antimicrobial resistance, DNA replication and DNA integration. This study provides preliminary information on putative Zn-binding proteins of Xtu which may further help in designing new metal-based antimicrobial agents for controlling BLS and bacterial chaff infections on staple crops.

description: Optimization and uncertainty quantification have been playing an increasingly important role in computational hemodynamics. However, existing methods based on principled modeling and classic numerical techniques have faced significant challenges, particularly when it comes to complex 3D patient-specific shapes in the real world. First, it is notoriously challenging to parameterize the input space of arbitrarily complex 3-D geometries. Second, the process often involves massive forward simulations, which are extremely computationally demanding or even infeasible. We propose a novel deep learning surrogate modeling solution to address these challenges and enable rapid hemodynamic predictions. Specifically, a statistical generative model for 3-D patient-specific shapes is developed based on a small set of baseline patient-specific geometries. An unsupervised shape correspondence solution is used to enable geometric morphing and scalable shape synthesis statistically. Moreover, a simulation routine is developed for automatic data generation by automatic meshing, boundary setting, simulation, and post-processing. An efficient supervised learning solution is proposed to map the geometric inputs to the hemodynamics predictions in latent spaces. Numerical studies on aortic flows are conducted to demonstrate the effectiveness and merit of the proposed techniques.

description: The role of committed minorities in shaping public opinion has been recently addressed with the help of multi-agent models. However, previous studies focused on homogeneous populations where zealots stand out only for their stubbornness. Here, we consider the more general case in which individuals are characterized by different propensities to communicate. In particular, we correlate commitment with a higher tendency to push an opinion, acknowledging the fact that individuals with unwavering dedication to a cause are also more active in their attempts to promote their message. We show that these \textit{activists} are not only more efficient in spreading their message but that their efforts require an order of magnitude fewer individuals than a randomly selected committed minority to bring the population over to a new consensus. Finally, we address the role of communities, showing that partisan divisions in the society can make it harder for committed individuals to flip the status-quo social consensus.

description: While many physical processes are non-equilibrium in nature, the theory and modeling of such phenomena lag behind theoretical treatments of equilibrium systems. The diversity of powerful theoretical tools available to describe equilibrium systems has inspired strategies that map non-equilibrium systems onto equivalent equilibrium analogs so that interrogation with standard statistical mechanical approaches is possible. In this work, we revisit the mapping from the non-equilibrium random sequential addition process onto an equilibrium multi-component mixture via the replica method, allowing for theoretical predictions of non-equilibrium structural quantities. We validate the above approach by comparing the theoretical predictions to numerical simulations of random sequential addition.

Publisher: name: Digital Repository at the University of Maryland
Year: 1978

description: The evolution of the teaching of history at the University of Maryland reflects both the changing role of history as a course of study and the altered status of history as a scholarly discipline. After a succession of history teachers with degrees in English or political science, the first professor with a history Ph.D., Hayes Baker-Crothers, came to Maryland in 1925. Other trained historians followed, but growth was slow. In 1940, President H.C. Byrd hired Wesley M. Gewehr to head the History Department. In the wake of stresses of World War II, dissension between Byrd and Gewehr caused even more neglect than might otherwise have accrued to a "service" department. History appointments, salaries, and facilities all suffered from Byrd's hostility throughout his administration. Four years after Byrd resigned in 1954, Gewehr retired, leaving to his successor, Aubrey C. Land, the task of developing a true university department with the support of the new president, Wilson H. Elkins. With worthwhile objectives but an abrasive manner, Land alienated a significant number of his senior faculty, especially those who had been close to Gewehr. Eventually, Land lost the confidence and support of the administration and withdrew as department head. An interim committee administered the department under the direction of Dean Charles Manning until a new chairman, David A. Shannon, was chosen in 1965. A recognized scholar, Shannon attracted a number of distinguished historians in a variety of scholarly fields before departing after three years. With a faculty of achievement and promise, the University of Maryland moved to capitalize on its advantageous location near the nation's capital to establish a History Department of the first rank.

description: In this paper, we assess the impact of numerical resolution and of the implementation of energy input from AGN feedback models on the inner structure of cluster sub-haloes in hydrodynamic simulations. We compare several zoom-in re-simulations of a sub-sample of the cluster-sized haloes studied in Meneghetti et al. (2020), obtained by varying mass resolution, softening length and AGN energy feedback scheme. We study the impact of these different setups on the subhalo abundances, their radial distribution, their density and mass profiles and the relation between the maximum circular velocity, which is a proxy for subhalo compactness. Regardless of the adopted numerical resolution and feedback model, subhaloes with masses Msub < 1e11Msun/h, the most relevant mass-range for galaxy-galaxy strong lensing, have maximum circular velocities ~30% smaller than those measured from strong lensing observations of Bergamini et al. (2019). We also find that simulations with less effective AGN energy feedback produce massive subhaloes (Msub> 1e11 Msun/h ) with higher maximum circular velocity and that their Vmax - Msub relation approaches the observed one. However the stellar-mass number count of these objects exceeds the one found in observations and we find that the compactness of these simulated subhaloes is the result of an extremely over-efficient star formation in their cores, also leading to larger-than-observed subhalo stellar mass. We conclude that simulations are unable to simultaneously reproduce the observed stellar masses and compactness (or maximum circular velocities) of cluster galaxies. Thus, the discrepancy between theory and observations that emerged from the analysis of Meneghetti et al. (2020) persists. It remains an open question as to whether such a discrepancy reflects limitations of the current implementation of galaxy formation models or the LCDM paradigm.

description: Topological insulators have emerged as a major topic of condensed matter physics research with several novel applications proposed. Although there are now a number of established experimental examples of materials in this class, all of them can be described by theories based on electronic band structure, which implies that they do not possess electronic correlations strong enough to fundamentally change this theoretical description. Here, we review recent theoretical progress in the description of a class of strongly correlated topological insulators - fractionalized topological insulators - where band theory fails dramatically due to the fractionalization of the electron into other degrees of freedom.

description: The aim of the study was to develop strategies to produce an oral contraceptive vaccine for mice in plants, in order to reduce the mouse population. The results showed that mouse-specific contraceptive peptides were successfully produced in plants. All peptides induced IgG antibodies in subcutaneously vaccinated mice. Moreover, oral delivery of the leaves expressing a fusion protein elicited systemic and mucosal cross-reactive antibodies. Observations suggest that plant-produced contraceptives have the potential to be used in the development of feeding baits to reduce the fertility of mice.

description: Direct-drive is an important approach to achieving the ignition of inertial confinement fusion. To enhance implosion performance while keeping the risk of hydrodynamic instability at a low level, we have designed a procedure to optimize the parameters of the target doped with mid- or high-$Z$ atoms. In the procedure, a one-dimensional implosion can be automatically simulated, while its implosion performance and high-dimensional instability are integrally evaluated at the same time. To find the optimal doping parameters, the procedure is performed in the framework of global optimization algorithm, where we have used the particle swarm optimization in the current work. In the optimization, the opacity of mixture materials is quickly obtained by using an interpolation method, showing only a slight difference from the data of TOPS, which is an online doping program of Los Alamos National Laboratory. To test the procedure, optimization has been carried out for the CH ablator in the double cone ignition scheme [Phil. Trans. R. Soc. A. 378.2184 (2020)] by doping with Si and Cl. Both one- and two-dimensional simulations show that doping with either Si or Cl can efficiently mitigate the instability during the acceleration phase and does not result in significant degradation of the peak areal density. The results from one- and two-dimensional simulations qualitatively match with each other, demonstrating the validity of our optimization procedure.

description: Isolated solid-state atomic defects with telecom optical transitions are ideal quantum photon emitters and spin qubits for applications in long-distance quantum communication networks. Prototypical telecom defects such as erbium suffer from poor photon emission rates, requiring photonic enhancement using resonant optical cavities. Many of the traditional hosts for erbium ions are not amenable to direct incorporation with existing integrated photonics platforms, limiting scalable fabrication of qubit-based devices. Here we present a scalable approach towards CMOS-compatible telecom qubits by using erbium-doped titanium dioxide thin films grown atop silicon-on-insulator substrates. From this heterostructure, we have fabricated one-dimensional photonic crystal cavities demonstrating quality factors in excess of $5\times10^{4}$ and corresponding Purcell-enhanced optical emission rates of the erbium ensembles in excess of 200. This easily fabricated materials platform represents an important step towards realizing telecom quantum memories in a scalable qubit architecture compatible with mature silicon technologies.

description: Любая социально-экономическая система является сложной для прогнозирования, поскольку в ней взаимодействует огромное множество социальных, экономических и технических объектов и процессов, постоянно изменяющихся под влиянием внешних условий и научно-технического прогресса. Ещё одной особенностью прогнозирования развития сложных систем является их слабая структурированность. Для управления социально-экономическими системами необходимы специальные методы и средства, так как благодаря проведению предварительного анализа работы системы при помощи моделирования появляется возможность выбора оптимального сценария развития. В статье рассматриваются особенности функционирования и описания транспортной составляющей социально-эконмических систем. Для выбора наиболее эффективных управляющих воздействий на систему применён метод математического моделирования, использующий аппарат дискретной математики, а именно, теории графов.

description: One of the most striking features of novel 2D semiconductors (e.g., transition metal dichalcogenide monolayers or phosphorene) is a strong Coulomb interaction between charge carriers resulting in large excitonic effects. In particular, this leads to the formation of multi-carrier bound states upon photoexcitation (e.g., excitons, trions and biexcitons), which could remain stable at near-room temperatures and contribute significantly to optical properties of such materials. In the present work we have used the Path Integral Monte Carlo methodology to numerically study properties of multi-carrier bound states in 2D semiconductors. Specifically, we have accurately investigated and tabulated the dependence of single exciton, trion and biexciton binding energies on the strength of dielectric screening, including the limiting cases of very strong and very weak screening. The results of this work are potentially useful in the analysis of experimental data and benchmarking of theoretical and computational models.

description: The central problem of strip theory is the calculation of potential flowaround 2D sections. One particular method of solutions to this problem is conformal mapping of the body section to the unit circle over which a solution of potential flow is available. Here, a new multiparameter conformal mapping method is presented that can map any arbitrary section onto a unit circle with good accuracy. The procedure for finding the corresponding mapping coefficients is iterative. The suggested mapping technique is shown to be capable of appropriately mapping any chined, bulbous, and large and fine sections. Several examples of mapping symmetric and nonsymmetric sections are demonstrated. For symmetric and nonsymmetric sections, the results of the current method are compared against other mapping techniques, and the currently produced geometries display good agreement with the actual geometries.

description: In solar wind, magnetohydrodynamic (MHD) discontinuities are ubiquitous and often found to be at the origin of turbulence intermittency. They may also play a key role in the turbulence dissipation and heating of the solar wind. The tangential (TD) and rotational (RD) discontinuities are the two most important types of discontinuities. Recently, the connection between turbulence intermittency and proton thermodynamics has been being investigated observationally. Here we present numerical results from three-dimensional MHD simulation with pressure anisotropy and define new methods to identify and to distinguish TDs and RDs. Three statistical results obtained about the relative occurrence rates and heating effects are highlighted: (1) RDs tend to take up the majority of the discontinuities along with time; (2) the thermal states embedding TDs tend to be associated with extreme plasma parameters or instabilities, while RDs do not; (3) TDs have a higher average T as well as perpendicular temperature $T_\perp$. The simulation shows that TDs and RDs evolve and contribute to solar wind heating differently. These results will inspire our understanding of the mechanisms that generate discontinuities and cause plasma heating.

description: Цифровизация экономики национального хозяйства предполагает активизацию инновационно-технологического развития российской Федерации, формирование единого инновационного пространства. Ожидается, что такой подход позволит эффективно реализовать инновационный потенциал в рамках региональных инновационных систем и усилит интеграционные процессы между субъектами РФ, органами госуправления, вузами, НИИ и хозяйствующими субъектами. Анализ специальной научной литературы показывает, что даже на федеральном уровне все еще нет единой концепции развития национальной инновационной экономики, отсутствует точная общепринятая инновационная терминология, что не позволяет получить единообразное понимание и применение инновационного законодательства всеми участниками данного процесса. Очевидна необходимость упорядочения действующего законодательства в области инновационной деятельности в Российской Федерации, закрепляющего нормы права о предмете и субъектах инновационных отношений, источников финансирования и мер господдержки инновационной деятельности. Построение и задействование инновационного потенциала на уровне субъектов Российской Федерации стали актуальной задачей, так как их решение позволит регионам выйти на траекторию устойчивого экономического роста. Реализовать инновационный потенциал возможно лишь при активном (достаточном) бюджетном и внебюджетном финансировании. Нормативно-правовая база функционирования системы внебюджетных фондов характеризуется рядом существенных недостатков, что негативно сказывается на эффективности деятельности этих фондов. Эксперты указывают, что в депрессивных республиках Северного Кавказа имеется ряд институциональных и организационных ограничений при реализации инновационного потенциала региональной экономической системы, также отмечается наличие разрывов в технологическом и инновационном развитии, что, однозначно, не позволяет сформировать единое инновационное пространство северокавказского региона. Безусловно, процессы построения, популяризации и задействования инноваций в разных странах существенно разнятся, ибо это зависит от размера территорий, от наличия природных, трудовых и иных ресурсов, от национальных особенностей осуществления инновационных процессов, от скорости внедрения и диффузии инноваций, от развитости институциональной среды. На наш взгляд, все это требует дальнейшего исследования с целью разработки механизма реализации инновационного потенциала в системе обеспечения конкурентоспособности развития региональной экономики, что и обеспечило выбор темы исследования.
Scaling behaviours of the $p_{T}$ spectra for identified hadrons in $pp$ collisions

description: We extend the scaling behaviour observed in the inclusive charged hadron transverse momentum ($p_{T}$) distributions to the $p_{T}$ spectra of pions, kaons and protons produced in proton-proton ($pp$) collisions with center of mass energies ($\sqrt{s}$ ) at 0.9, 2.76 and 7 TeV. This scaling behaviour arises when a linear transformation, $p_{T} \rightarrow p_{T}/K$, is applied on the pion, kaon or proton $p_{T}$ spectra. The scaling parameter $K$ depends on $\sqrt{s}$ and is determined by a new method, the quality factor method, which does not rely on the shape of the scaling function. We argue that the pions, kaons and protons originate from different distributions of clusters which are formed by strings overlapping, and the scaling behaviours of these identified particles $p_{T}$ spectra could be understood with the colour string percolation model in a quantitative way simultaneously.

description: В процессе осуществления хозяйственной деятельности любая коммерческая организация вступает в различные отношения с другими экономическими субъектами. Результаты осуществления взаимо-действия организации с контрагентами неизбежно отражаются на всех остальных областях деятельности организации. Основанием для проведения анализа дебиторской и кредиторской задолженности являются данные бухгалтерской финансовой отчетности организации, однако в данных формах отчетности расчеты с дебиторами и кредиторами отражаются кратко. Более подробно расчеты отражаются во внутренних формах отчетности организации. С целью оценки влияния дебиторской и кредиторской задолженности на финансовую устойчивость и ликвидность коммерческой организации в статье был произведен анализ оборачиваемости дебиторской и кредиторской задолженности конкретной коммерческой организации, рассчитан период их оборачиваемости. Период оборачиваемости зависит от многих факторов, в частности от отрасли, в которой работает исследуемая организация, от объемов ее деятельности и т.д.

description: Формирование и закрепление хозяйственных связей выступают необходимыми условиями деятельности организации, так как они обеспечивают непрерывность процесса реализации продукции. Оформляются и закрепляются хозяйственные связи договорами и контрактами, согласно которым одно предприятие выступает поставщиком продукции, работ, услуг, а другое их покупателем, потребителем. Важно отметить, что четкая организация расчетов между поставщиками и покупателями оказывает непосредственное влияние на ускорение оборачиваемости оборотных средств и своевременное поступление денежных средств. Получить реальную картину результатов относительно предпринимательской и финансовохозяйственной деятельности организации позволяет система показателей, характеризующих динамические изменения, произошедшие в течение трех последних лет, сравнительный анализ которых проводится при выполнении условия сопоставимости данных. Анализ проводится на основании данных бухгалтерской (финансовой) отчетности организации. Для хозяйствующих субъектов достаточно важное значение приобретает их финансовая независимость от внешних заемных источников. Особенно это актуально в современных условиях экономической самостоятельности и независимости организаций.

description: We start with a variational approach and derive a set of coupled integral equations for the bound states of $N$ identical spin-$\uparrow$ fermions and a single spin-$\downarrow$ fermion in a generic multiband Hubbard Hamiltonian with an attractive onsite interaction. As an illustration we apply our integral equations to the one-dimensional sawtooth lattice up to $N \le 3$, i.e., to the $(3+1)$-body problem, and reveal not only the presence of tetramer states in this two-band model but also their quasi-flat dispersion when formed in a flat band. Furthermore, for $N = \{4, 5, \cdots, 10 \}$, our DMRG simulations and exact diagonalization suggest the presence of larger and larger multimers with lower and lower binding energies, conceivably without an upper bound on $N$. These peculiar $(N+1)$-body clusters are in sharp contrast with the exact results on the single-band linear-chain model where none of the $N \ge 2$ multimers appear. Hence their presence must be taken into account for a proper description of the many-body phenomena in flat-band systems, e.g., they may suppress superconductivity especially when there exists a large spin imbalance.

description: В статье рассматриваются вопросы развития цифровой экономики, начиная с 1995 года, когда только начиналось интенсивное развитие информационно-коммуникационных технологий. Очевидно, что развитие интернета и мобильных коммуникаций являются базовыми технологиями современной цифровой экономики. Но в итоге эти процессы повлияли на все секторы экономики и социальной деятельности, в том числе производство, здравоохранение, образование, финансовые услуги, транспорт и т. д. По определению Всемирного банка, цифровая экономика – это система экономических, социальных и культурных отношений, основанных на использовании цифровых информационно-коммуникационных технологий. Развитие технологической инфраструктуры и использование больших баз данных вызвали масштабную цифровую трансформацию нашего общества. Авторы рассматривают последовательное развитие этапов глобальной цифровизации, которые характеризуются расширением доступа в интернет для миллионов потребителей, и переходом на вышестоящий уровень интеграции широкого спектра цифровых сервисов, продуктов и систем в киберфизическую систему.
