description: The noncommutative spacetimes associated to the $κ$-Poincaré relativistic symmetries and their "non-relativistic" (Galilei) and "ultra-relativistic" (Carroll) limits are indistinguishable, since their coordinates satisfy the same algebra. In this work, we show that the three quantum kinematical models can be differentiated when looking at the associated spaces of time-like worldlines. Specifically, we construct the noncommutative spaces of time-like geodesics with $κ$-Galilei and $κ$-Carroll symmetries as contractions of the corresponding $κ$-Poincaré space and we show that these three spaces are defined by different algebras. In particular, the $κ$-Galilei space of worldlines resembles the so-called Euclidean Snyder model, while the $κ$-Carroll space turns out to be commutative. Furthermore, we identify the map between quantum spaces of geodesics and the corresponding noncommutative spacetimes, which requires to extend the space of geodesics by adding the noncommutative time coordinate.

description: We discuss the effect of chemical separation as matter freezes at the base of the ocean of an accreting neutron star, and the subsequent enrichment of the ocean in light elements and inward transport of heat through convective mixing. We extend the steady-state results of Medin & Cumming 2011 to transiently accreting neutron stars, by considering the time-dependent cases of heating during accretion outbursts and cooling during quiescence. Convective mixing is extremely efficient, flattening the composition profile in about one convective turnover time (weeks to months at the base of the ocean). During accretion outbursts, inward heat transport has only a small effect on the temperature profile in the outer layers until the ocean is strongly enriched in light elements, a process that takes hundreds of years to complete. During quiescence, however, inward heat transport rapidly cools the outer layers of the ocean while keeping the inner layers hot. We find that this leads to a sharp drop in surface emission at around a week followed by a gradual recovery as cooling becomes dominated by the crust. Such a dip should be observable in the light curves of these neutron star transients, if enough data is taken at a few days to a month after the end of accretion. If such a dip is definitively observed, it will provide strong constraints on the chemical composition of the ocean and outer crust.

description: The possible existence of hybrid stars is studied using several multi-quark interaction channels. The hadronic phase consists of an equation of state (EoS) with presently accepted nuclear matter properties and the quark model is constrained by the vacuum properties of several light mesons. The dependence of several NS properties on the different quark interactions is analyzed. We show that the present constraints from neutron star observations allow for the existence of hybrid stars with large strangeness content and large quark cores.

description: Using the self-consistent field lattice model, polymer concentration $\barϕ_{P}$ and chain length $N$ (keeping the length ratio of hydrophobic to hydrophilic blocks constant) the effects on temperature-dependent behavior of micelles are studied, in amphiphilic symmetric ABA triblock copolymer solutions. When chain length is increased, at fixed $\barϕ_{P}$, micelles occur at higher temperature. The variations of average volume fraction of stickers $\barϕ_\textrm{co}^\textrm{s}$ and the lattice site numbers $N_\textrm{co}^\textrm{ls}$ at the micellar cores with temperature are dependent on $N$ and $\barϕ_{P}$, which demonstrates that the aggregation of micelles depends on $N$ and $\barϕ_{P}$. Moreover, when $\barϕ_{P}$ is increased, firstly a peak appears on the curve of specific heat $C_V$ for unimer-micelle transition, and then in addition a primary peak, the secondary peak, which results from the remicellization, is observed on the curve of $C_V$. For a long chain, in intermediate and high concentration regimes, the shape of specific heat peak markedly changes, and the peak tends to be a more broad peak. Finally, the aggregation behavior of micelles is explained by the aggregation way of amphiphilic triblock copolymer. The obtained results are helpful in understanding the micellar aggregation process.

Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: We present measurements of the nuclear modification factors RAA and RpA(PYTHIA) of b jets in lead-lead and proton-lead collisions, respectively, using the CMS detector. Jets from b-quark fragmentations are found by exploiting the long lifetime of the b-quark through tagging methods using distributions of the secondary vertex displacement. From these, b-jet cross-sections are calculated and compared to the pp cross-section from the 2.76 TeV pp data collected in 2013 and to a PYTHIA simulation at 5.02 TeV, where these center-of-mass energies correspond to those of the PbPb and pPb data. We observe significant suppression for b jets in PbPb, and a RpA(PYTHIA) value consistent with unity for b jets in pPb. Results from both collision species show remarkable correspondence with inclusive-jet suppression measurements, indicating that mass-dependent energy-loss effects are negligible at pT values greater than around 50 GeV/c. We use 150 inverse μb of lead-lead data and 35 inverse nb of proton-lead data collected at the LHC.

description: Relativistic reflection observed in the hard states of accreting black holes often shows a weak amplitude relative to the main Comptonization component, which may result from either a disc truncation or a non-isotropy of the X-ray source, e.g. due to a motion away from the reflector. We investigate here the latter case, assuming that the X-ray source is located on the symmetry axis of the Kerr black hole. We discuss effects relevant to a proper computation of the reflected radiation and we implement them in the model for data analysis, reflkerrV. We apply it to the simultaneous Suzaku and NuSTAR observation of Cyg X-1 in the hard state and we find a good fit for an untruncated disc irradiated by the source moving away from it at 0.36c. However, we find a slightly better solution in a geometry closely approximating the truncated disc irradiated by an inner hot flow. In this solution we either still need a subrelativistic outflow or the source opposite to the observer must contribute to the directly observed radiation. We also discuss differences between the implementation of the outflow effect in reflkerrV and in relxilllpCp.

Radical ideas of political practice in 1780s and 1790s Britain
Creators: name: Westwell, Amy
Publisher: name: University of St Andrews
Year: 2020

description: This thesis examines ideas about political tactics in 1780s and 1790s Britain. Edmund Burke characterised radicals in the aftermath of the French Revolution as speculative thinkers with no understanding of political action. This rhetorical strategy obscured the ideas of reformers who were frustrated with the rationalist bent of their movement and who, inspired by Scottish philosophy and events in Ireland, tried to work out what was to be done. James Mackintosh and Samuel Parr responded to Burke by arguing that theory could apply to practice, while David Williams outlined how political theory could direct reformers to the means to harness the general will and enact it through the sovereign. Interest in arming the people led David Steuart Erskine, Robert Watson, and John Cartwright to invoke the ideas of Andrew Fletcher. This interest in a militia was not purely theoretical; in Ireland from 1778 the Volunteers used a combination of arms and sumptuary rules to win legislative and trading rights. Francis Dobbs, Joseph Pollock and Henry Flood examined this movement to learn about political tactics. Lord George Gordon advocated for Francis Dobbs in the House of Commons and was imprisoned for his attempts to derail the Anglo-French Commercial Treaty, an issue that once again brought together Irish politics and discussions of commerce and luxury. In the 1790s, United Irishmen linked their understanding of the anti-luxury practice of the Volunteers with knowledge of the constitution they had learned from John Millar at Glasgow University. Meanwhile, Lord Buchan was using an unlikely tactic, the practice of history, to stir the Scots to pay attention to their Buchananite heritage. The tactical thought of British radicals in the 1790s was rarely concerned with discussions of the rights of man, but instead referred to ideas of arms, kings, commerce, and history.

description: We investigate the motion of groups of intruders in a two-dimensional granular system by using discrete numerical simulations. By imposing either a constant velocity or a thrusting force on larger disks (intruders) that move within smaller ones (grains), we obtained instantaneous positions and components of forces for each intruder and grain. We found that (i) intruders cooperate even when at relatively large distances from each other; (ii) the cooperative dynamics is the result of contact chains linking the intruders as well as compaction and expansion of the granular medium in front and behind, respectively, each intruder; (iii) the collaborative behavior depends on the initial arrangement of intruders; and (iv) for some initial arrangements, the same spatial configuration is eventually reached. Finally, we show the existence of an optimal distance for minimum drag for a given set of intruders, which can prove useful for devices stirring the ground or other granular surfaces.

description: The characteristics of topological insulators are manifested in both their surface and bulk properties, but the latter remain to be explored. Here we report bulk signatures of pressure-induced band inversion and topological phase transitions in Pb$_{1-x}$Sn$_x$Se ($x=$0.00, 0.15, and 0.23). The results of infrared measurements as a function of pressure indicate the closing and the reopening of the band gap as well as a maximum in the free carrier spectral weight. The enhanced density of states near the band gap in the topological phase give rise to a steep interband absorption edge. The change of density of states also yields a maximum in the pressure dependence of the Fermi level. Thus our conclusive results provide a consistent picture of pressure-induced topological phase transitions and highlight the bulk origin of the novel properties in topological insulators.

description: This contribution traces the transition of Canada's national history museum from the Canadian Museum of Civilization (CMC) to the Canadian Museum of History (CMH) due to open on 1 July 2017 in time for national celebrations of the 150th anniversary of Canadian Confederation. The article examines the very different approaches to museology and historical representation that became visible as the CMC's Canada Hall was demolished to make way for the CMH's Canadian History Hall. This significant change in the Canadian commemorative landscape was seen by many as part of a deliberate refashioning by the Conservative government and by others an as opportunity to tell new stories in new ways. The making of the new history hall is situated in the context of larger debates about history and memory, the role of museums in shaping national identity, and public perceptions about museums.

description: Усовершенствован состав бобово-глютенового концентрата. В качестве прототипа взят ранее испытанный бобово-глютеновый концентрат (БГК), который содержит дорогой и сравнительно дефицитный кукурузный глютен, а также рыбий жир. В состав бобово-жмыхового концентрата введены, в %: 45 полножирная автоклавированная соя; 35 ошелушенный экструдированный люпин; 14 под-солнечный жмых и 6 аминокислоты и комплекс биологически активных веществ нового поколения. По прямым затратам средств произведен расчет экономической эффективности использования в комбикормах различных обогатительных концентратов, созданных на основе растительного белка и биологически активных веществ нового поколения. Замена в БГК дорогостоящего кукурузного глютена подсолнечным жмыхом снизила на 7% стоимость добавки без ухудшения ее качества. Среднесуточные приросты свиней в опытной группе превосходили привесы контрольных животных на 27 г или на 4,1% (685 против 658 г), а затраты комбикорма были ниже на 3,91%. Можно обоснованно утверждать, что обогатительную добавку для комбикормов можно производить без дефицитного, дорогостоящего кукурузного глютена, используя наиболее доступное сырье бобовых культур (соя, люпин) и подсолнечный жмых. Бобово-жмыховый концентрат найдет применение в крупных свиноводческих хозяйствах, имеющих собственную кормовую базу, а также на комбикормовых предприятиях.The legume-gluten concentrate structure is improved. As a prototype the earlier tested legume-gluten concentrate (BGK), containing expensive and relatively the deficit corn gluten and fish oil is used. In the composition of legume-and-pomace concentrate are introduced, %: 45 full fat autoclaved soy; 35 -hulling extruded lupine; 14 sunflower pomace and 6 amino acids and complex of biologically active substances of new generation. The calculation of economic efficiency had done on direct costs using in combined feed of different enriched concentrates, made on vegetative protein protein and new generation’s biologically active substances’ base. The replace in the BGK of costly corn gluten by sunflower pomace decreased in 7% the cost of the additive without its quality deterioration. The average daily gains of pigs in the experimental group exceeded the ones of control animals in 27g or in 4,1% (685 versus 658 g), and the costs of combined feed were lower in 3,91%. It can reasonably be argued that enriched additive for combined feed can be produced without deficit, expensive corn gluten using the most available raw of legumes (soy, lupine) and sunflower pomace. Legume-pomace concentrate can found its application in large-scale pig farms with their own forage base, and on combined feed’plants.

description: Сегодня мелкий сельскохозяйственный производитель в России нуждается в поддержке государства путем создания условий вхождения производимого товара или услуг на рынок. Для реализации этого механизма предлагается формировать государственные торговые сети, работающие по принципам крупного ритейла. Для обеспечения конкурентоспособности государственным торговым сетям необходимо применять коммуникационные методики: формирование бренда торговых сетей, применение методик интегрированных маркетинговых коммуникаций. Такой подход позволит в короткий период укрепить рынок мелкого сельхозпроизводителя, а рядовые покупатели смогут получить продукцию, по условиям реализации альтернативную продукции крупного и среднего ритейла.Today the small farm producer in Russia needs state support by the manufactured goods or services on the market entry conditions’ establishing. For this mechanism implement it is proposed to form a state trading networks operating according to the large retailers principles.

This approach will allow to strengthen in a short period the market of small farm producer, and ordinary customers will be able to receive products in terms of the implementation as alternative of large and medium-sized retailers productivity.

description: We construct and analyze a rate-based neural network model in which self-interacting units represent clusters of neurons with strong local connectivity and random inter-unit connections reflect long-range interactions. When sufficiently strong, the self-interactions make the individual units bistable. Simulation results, mean-field calculations and stability analysis reveal the different dynamic regimes of this network and identify the locations in parameter space of its phase transitions. We identify an interesting dynamical regime exhibiting transient but long-lived chaotic activity that combines features of chaotic and multiple fixed-point attractors.

description: Physics-based solar cycle predictions provide an effective way to verify our understanding of the solar cycle. Before the start of cycle 25, several physics-based solar cycle predictions were developed. These predictions use flux transport dynamo (FTD) models, surface flux transport (SFT) models, or a combination of the two kinds of models. The common physics behind these predictions is that the surface poloidal fields around cycle minimum dominate the subsequent cycle strength. In the review, we first give short introductions to SFT and FTD models. Then we compare 7 physics-based prediction models from 4 aspects, which are what the predictor is, how to get the predictor, how to use the predictor, and what to predict. Finally, we demonstrate the large effect of assimilated magnetograms on predictions by two SFT numerical tests. We suggest that uncertainties in both initial magnetograms and sunspot emergence should be included in such physics-based predictions because of their large effects on the results. In addition, in the review we put emphasis on what we can learn from different predictions, rather than an assessment of prediction results.

Motion estimation for fisheye video sequences combining perspective projection with camera calibration information

description: Fisheye cameras prove a convenient means in surveillance and automotive applications as they provide a very wide field of view for capturing their surroundings. Contrary to typical rectilinear imagery, however, fisheye video sequences follow a different mapping from the world coordinates to the image plane which is not considered in standard video processing techniques. In this paper, we present a motion estimation method for real-world fisheye videos by combining perspective projection with knowledge about the underlying fisheye projection. The latter is obtained by camera calibration since actual lenses rarely follow exact models. Furthermore, we introduce a re-mapping for ultra-wide angles which would otherwise lead to wrong motion compensation results for the fisheye boundary. Both concepts extend an existing hybrid motion estimation method for equisolid fisheye video sequences that decides between traditional and fisheye block matching in a block-based manner. Compared to that method, the proposed calibration and re-mapping extensions yield gains of up to 0.58 dB in luminance PSNR for real-world fisheye video sequences. Overall gains amount to up to 3.32 dB compared to traditional block matching.

We argue that the exponent $β_{\rm osc}$ characterising the scale of the interfacial height $\ell_0 \propto R_w^{β_{\rm osc}}$ at osculation, for large $R_w$, falls into two regimes representing fluctuation-dominated and mean-field like behaviour, respectively. These two regimes are separated by an upper critical dimension, which is determined here explicitly and which depends on the range of the intermolecular forces. In the fluctuation-dominated regime, representing the universality class of systems with short-ranged forces, the exponent is related to the value of the interfacial wandering exponent $ζ$ by $β_{\rm osc}=3ζ/(4-ζ)$. In contrast, in the mean-field regime, which has not been previously identified, and which occurs for systems with longer ranged forces (and higher dimensions), the exponent $β_{\rm osc}$ takes the same value as the exponent $β_s^{\rm co}$ for complete wetting which is determined directly by the intermolecular forces. The prediction $β_{\rm osc}=3/7$ in $d=2$ for systems with short-ranged forces (corresponding to $ζ=1/2$) is confirmed using an interfacial Hamiltonian model which determines the exact scaling form for the decay of the interfacial height probability distribution function. A numerical study in $d=3$, based on a microscopic model Density Functional Theory, determines that $β_{\rm osc} \approx β_s^{\rm co}\approx 0.326$ close to the predicted value $1/3$ appropriate to the mean-field regime for dispersion forces.

description: Excerpts from the report Summary: The dissemination of current and reliable market information to all segments of the marketing system is essential if that system is to operate competitively and efficiently. To keep abreast of the increasing complexities of wool market reporting brought about by changes in the marketing system, the Consumer and Marketing Service (C&MS) proposed a joint research project with the Economic Research Service. Available wool marketing information did not appear to fully meet the needs of producers and local buyers for making decisions. C&MS particularly wanted to know whether their livestock news reporters, who were already in the wool producing areas, could also serve as wool reporters.

description: To obtain depth information from a stereo camera setup, a common way is to conduct disparity estimation between the two views; the disparity map thus generated may then also be used to synthesize arbitrary intermediate views. A straightforward approach to disparity estimation is block matching, which performs well with perspective data. When dealing with non-perspective imagery such as obtained from ultra wide-angle fisheye cameras, however, block matching meets its limits. In this paper, an adapted disparity estimation approach for fisheye images is introduced. The proposed method exploits knowledge about the fisheye projection function to transform the fisheye coordinate grid to a corresponding perspective mesh. Offsets between views can thus be determined more accurately, resulting in more reliable disparity maps. By re-projecting the perspective mesh to the fisheye domain, the original fisheye field of view is retained. The benefit of the proposed method is demonstrated in the context of intermediate view synthesis, for which both objectively evaluated as well as visually convincing results are provided.

description: Рассмотрен вопрос снижения потерь азота навоза для обеспечения сохранности почвенного плодородия и соблюдения требований защиты окружающей среды от загрязнений. Отмечено, что одними из самых важных и экономически эффективных мер сокращения потерь азота и вредных выбросов, образующихся в результате этих потерь, являются мероприятия, связанные с подготовкой и использованием органических удобрений на основе навоза животных. Представлены результаты исследований влияния трех наиболее часто используемых в России технических средств удаления навоза на процесс потерь азота в производственных условиях животноводческих помещений двух ферм молочного направления при привязной и беспривязной системе содержания животных. Результаты исследования показали: максимальный процент потерь азота получен при удалении навоза скребковым транспортером ТСН-160 из открытого канала. Он составил 32,3%, то есть теряется почти треть общего азота и почти весь азот в легко усвояемой форме. На втором месте по потерям общего азота оказалась скреперная установка с возвратно-поступательным перемещением, потери при ее использовании составили 16,8%. Минимальные потери азота (8,1%) получены у установленного под решетками шнекового транспортера.The issue of manure nitrogen losses reducing for soil fertility protection and compliance with environmental pollution safety is considered. It is noted that one of the most important and cost-effective means of nitrogen losses and harmful emissions reducing resulting from these losses, are activities associated with the organic fertilizers based on animal manure preparation and use. The studies’ results of three the most commonly used in Russia manure disposal technical means’ influence on the nitrogen losses process in livestock buildings industrial conditions on two dairy farms with tied and loose systems of animals’ housing are presented. The study results had shown that the nitrogen losses maximum percentage was derived at the manure disposal with TSN-160 scraper conveyor from the open channel. It was 32,3%, that is the third part of the total nitrogen and almost all the easily digestible form of nitrogen has almost lost. In second place of total nitrogen losses was the scraper installation with return -and progressive movement, its using losses were as 16,8 %. Minimal nitrogen losses (8,1%) were obtained from the screw conveyor installed under the grates.

description: Развитие современного животноводства отличается усилением интенсификации производства, что усиливает риски негативного влияния на окружающую среду. Наиболее значимым источником негативного воздействия животноводства является навоз. Для повышения экологической безопасности автор предлагает использовать принципы наилучших доступных технологий (НДТ), которые в настоящее время закреплены в российском природоохранном законодательстве и в ближайшие годы станут обязательными для проектирования крупных животноводческих предприятий. Ключевым принципом концепции НДТ является технологическое нормирование, основанное на комплексном учете как экономических, так и экологических показателей, причем экологические показатели должны учитывать все значимые виды негативного воздействия на окружающую среду. В статье рассматриваются вещества-загрязнители, характерные для процессов утилизации навоза. Методом логико-лингвистического моделирования (на основе экспертных оценок) была определена значимость влияния характерных веществ-загрязнителей. На основе полученных коэффициентов значимости веществ-загрязнителей сделан вывод о том, что наиболее значимое негативное воздействие на окружающую среду оказывают соединения азота, и предложен алгоритм проектирования технологии утилизации навоза на основе критериев НДТ.The development of modern livestock farming is characterized by increasing intensification of production, which increases the risk of a negative impact on the environment. The most significant source of livestock negative impact is manure. To improve ecological safety, the author proposes to use the principles of best available technologies (NDT), that currently are enshrined in the Russian nature protection legislation and in the nearest years will become mandatory for the large livestock enterprises design. A key principle of the NDT concept is a technological regulation, based on a complex accounting of both economic and ecological indicators, at that the ecological indicators should take into account all the significant types of negative impact on the environment. The article discusses substances-pollutants that are typical for the manure utilization processes. By the method of logic-and-linguistic modeling (based on expert appraisal) was determined the significance of the typical pollute substances' influence. Based on the substances polluting coefficients it is concluded that the most significant negative impact on the environment have a chemical compounds of nitrogen and an algorithm for the manure utilization technologies design, based on the NDT criteria.

description: We present the performance of MIMO for in vivo environments, using ANSYS HFSS and their complete human body model, to determine the maximum data rates that can be achieved using an IEEE 802.11n system. Due to the lossy nature of the in vivo medium, achieving high data rates with reliable performance will be a challenge, especially since the in vivo antenna performance is strongly affected by near field coupling to the lossy medium and the signals levels will be limited by specified specific absorption rate (SAR) levels. We analyzed the bit error rate (BER) of a MIMO system with one pair of antennas placed in vivo and the second pair placed inside and outside the body at various distances from the in vivo antennas. The results were compared to SISO simulations and showed that by using MIMO in vivo, significant performance gain can be achieved, and at least two times the data rate can be supported with SAR limited transmit power levels, making it possible to achieve target data rates in the 100 Mbps.
