description: We report the synthesizing and characterization of the hole doped Ni-based superconductor ($La_{1-x}Sr_{x})NiAsO$. By substituting La with Sr, the superconducting transition temperature $T_c$ is increased from 2.4 K of the parent phase $LaNiAsO$ to 3.7 K at the doping levels x= 0.1 - 0.2. The curve $T_c$ versus hole concentration shows a symmetric behavior as the electron doped samples $LaNiAs(O_{1-x}F_{x})$. The normal state resistivity in Ni-based samples shows a good metallic behavior and reveals the absence of spin density wave induced anomaly which appears in the Fe-based system at about 150 K. Hall effect measurements indicate that the electron conduction in the parent phase $LaNiAsO$ is dominated by electron-like charge carriers, while with more Sr doping, a hole-like band will emerge and finally prevail over the conduction, such a phenomenon reflects that the Fermi surface of $LaNiAsO$ comprises of electron pockets and hole pockets, thus the sign of charge carriers could be changed once the contribution of hole pockets overwhelms that of electron pockets. Magnetoresistance measurements and the violation of Kohler rule provide further proof that multiband effect dominate the normal state transport of ($La_{1-x}Sr_{x})NiAsO$.

description: We study a $b$-deformation of monotone Hurwitz numbers, obtained by deforming Schur functions into Jack symmetric functions. We give an evolution equation for this model and derive from it Virasoro constraints, thereby proving a conjecture of Féray on Jack characters. A combinatorial model of non-oriented monotone Hurwitz maps which generalizes monotone transposition factorizations is provided.
 In the case $b=1$ we obtain an explicit Schur expansion of the model and show that it obeys the BKP integrable hierarchy. This Schur expansion also proves a conjecture of Oliveira--Novaes relating zonal polynomials with irreducible representations of $O(N)$. We also relate the model to an $O(N)$ version of the Brézin--Gross--Witten integral, which we solve explicitly in terms of Pfaffians in the case of even multiplicities.

In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Bistability and hysteresis of magnetohydrodynamic dipolar dynamos generated by turbulent convection in rotating spherical fluid shells is demonstrated. Hysteresis appears as a transition between two distinct regimes of dipolar dynamos with rather different properties including a pronounced difference in the amplitude of the axisymmetric poloidal field component and in the form of the differential rotation. The bistability occurs from the onset of dynamo action up to about 9 times the critical value of the Rayleigh number for onset of convection and over a wide range of values of the ordinary and the magnetic Prandtl numbers including the value unity.

description: В статье рассматриваются результаты исследований по определению масти коров местного симментальского скота в условиях Якутии. В условиях Якутии разведение зонального типа скота должно быть экономически выгодным и скот будет иметь регионально ограниченное экономическое значение. Этот скот будет отличаться от других отечественных пород наибольшей приспособленностью к низкотемпературным климатическим и кормовым условиям Якутии, а также своей технологией содержания.Объектом исследования является местный симментальский скот. Масть определили окраской волосяного покрова животных. Основная масть исследованных коров — палевая, палево-пестрая и красно-пестрая. Много коров палево-пестрой и красно-пестрой с белой головой, у них на головах отсутствуют другие отметины. У большинства коров рога, носовое зеркало, копыта окрашены в розовый или светложелтый цвет. В результате исследования отмечено, что в обеих зонах (Центральная и Вилюйская) типичная масть коров варьируется от палевой до светло-палевого, редко встречаются животные красного окраса, как известно из них некоторые качественные признаки служат показателем принадлежности к зональному типу. Во всех хозяйствах из исследованных животных имеется цвет однотонный или разбавленный белыми отметинами на конечностях, нижней части туловища и по всему туловищу. У большинства животных носогубное зеркало, паховая зона, вымя и конечности у всех животных светлые, светлые волосы присутствуют возле губ, кисточка хвоста — белая или двухцветная. Данная работа является фрагментом общей программы создания нового желательного типа скота мясо-молочного направления в Якутии.

description: We derive the complete set of velocity-enhanced terms in the expansion of the total cross section for heavy-quark pair production in hadronic collisions at next-to-next-to-leading order. Our expression takes into account the effects of soft-gluon emission as well as that of potential-gluon exchanges. We prove that there are no enhancements due to subleading soft-gluon couplings multiplying the leading Coulomb singularity.

description: In this paper we are interested in a class of fuzzy numbers which is uniquely identified by their membership functions. The function space, denoted by $X_{h, p}$, will be constructed by combining a class of nonlinear mappings $h$ (subjective perception) and a class of probability density functions (PDF) $p$ (objective entity), respectively. Under our assumptions, we prove that there always exists a class of $h$ to fulfill the observed outcome for a given class of $p$. Especially, we prove that the common triangular number can be interpreted by a function pair $(h, p)$. As an example, we consider a sample function space $X_{h, p}$ where $h$ is the tangent function and $p$ is chosen as the Gaussian kernel with free variable $μ$. By means of the free variable $μ$ (which is also the expectation of $p(x; μ)$), we define the addition, scalar multiplication and subtraction on $X_{h, p}$. We claim that, under our definitions, $X_{h, p}$ has a linear algebra. Some numerical examples are provided to illustrate the proposed approach.

description: Additional file 3: Figure S2. IL4, IL10, IL6 and IFNγ pathways genes were upregulated in tumor-associated microglia. (A) The IL4 associated genes were mostly upregulated in tumor-associated microglia with increased expression in EV-GFPpos microglia. The significantly upregulated genes in EV-GFPpos versus EV-GFPneg microglia included known tumor supportive genes such as Mmp12, Adam19 and Wnt5a. (B) IL10 related genes were upregulated in tumor microglia. Sod2, a tumor supportive gene, was among the genes significantly upregulated in EV-GFPpos microglia. (C) IL6 related genes were upregulated in tumor-associated microglia. Among the significantly upregulated IL6 genes is Ccl7 (MCP-3), a secreted chemokine involved in the attraction of microglia and macrophages to the tumor suggesting a tumor supportive infiltration loop. (D) Overall, increased expression of IFNγ related genes was observed with the strongest expression in EV-GFPpos microglia. Among the significantly upregulated genes in EV-GFPpos microglia was Irf7, a key regulator of pro-inflammatory to anti-inflammatory switching in microglia.

Psychovisual video coding using wavelet transform
Creators: name: Gunawan, D
Publisher: name: University Of Tasmania

description: Visual communications services are now making a significant impact on modern society. Video conferencing, HDTV and multimedia are just examples where this technology is being used to good effect. Communicating using video signals does, however, require a large volume of data to be transmitted, and even with modern high-bandwidth communication links this can be expensive. This requires the implementation of efficient video coding and compression schemes. This thesis investigates both image and video coding compression schemes and aims to develop a scheme with the highest possible performance. In image coding there are two main types of compression: statistical and psychovisual. This thesis concentrates on the latter, since it is shown that psychovisual techniques, in general, provide greater levels of compression than statistically based methods. The standardised technique for video coding uses psychovisual compression of the coefficients of the discrete cosine transform (DCT). Despite being an international standard for low bit rate video coding the DCT suffers from a number of drawbacks. Firstly, the psychophysical and psychological models of the human visual system (HVS) are based on a multiresolution approach whereas the basis functions of the DCT are fixed in resolution. Secondly the basis functions of the DCT only possess good localisation properties in the frequency domain and not the spatial domain, a characteristic that blurs edges and discontinuities in an image. By contrast the wavelet transform is a multiresolution approach and its basis functions can possess good localisation properties in both the spatial and frequency domains. Furthermore, due to the excellent localisation properties of the wavelet function most of the transform coefficients are practically zero and the use of wavelet transform can be expected to achieve a higher compression ratio than the DCT. This thesis therefore investigates psychovisual transform coding using the wavelet transform instead of the DCT.

description: We analyze the decoherence induced on a single qubit by the interaction with a two-level boson system with critical internal dynamics. We explore how the decoherence process is affected by the presence of quantum phase transitions in the environment. We conclude that the dynamics of the qubit changes dramatically when the environment passes through a continuous excited state quantum phase transition. If the system-environment coupling energy equals the energy at which the environment has a critical behavior, the decoherence induced on the qubit is maximal and the fidelity tends to zero with finite size scaling obeying a power-law.

description: We propose finite-volume schemes for general continuity equations which preserve positivity and global bounds that arise from saturation effects in the mobility function. In the case of gradient flows, the schemes dissipate the free energy at the fully discrete level. Moreover, these schemes are generalised to coupled systems of non-linear continuity equations, such as multispecies models in mathematical physics or biology, preserving the bounds and the dissipation of the energy whenever applicable. These results are illustrated through extensive numerical simulations which explore known behaviours in biology and showcase new phenomena not yet described by the literature.

Рассмотрены детерминированные методы обнаружения плодов на основе анализа цвета, формы и текстуры объектов, применяемые в системах машинного зрения роботов, предназначенных для уборки урожая. Также рассмотрено применение к задаче обнаружения фруктов алгоритмов машинного обучения, основанных на классических методах классификации, регрессии и кластерного анализа, а также простейших нейросетевых моделей. Выявлены наиболее важные характеристики качества алгоритмов обнаружения фруктов: доля необнаруженных алгоритмом фруктов и доля объектов, ошибочно принятых алгоритмом за фрукты. Показано, что детерминированные методы и классические алгоритмы машинного обучения не позволяют (в отличие от современных глубоких сверточных нейронных сетей) обеспечить качество распознавания фруктов, достаточное для использования в системах машинного зрения реальных роботов для сбора урожая плодовых культур.

description: We report a time resolved imaging and micromagnetic simulation study of the relaxation dynamics of a magnetic vortex in the non-linear regime. We use time-resolved photoemission electron microscopy and micromagnetic calculations to examine the emergence of non-linear vortex dynamics in patterned Ni80Fe20 disks in the limit of long field pulses. We show for core shifts beyond ~20-25% of the disk radius, the initial motion is characterized by distortions of the vortex, a transient cross-tie wall state, and instabilities in the core polarization that influence the core trajectories.

description: Increasingly complex learning methods such as boosting, bagging and deep learning have made ML models more accurate, but harder to understand and interpret. A tradeoff between performance and intelligibility is often to be faced, especially in high-stakes applications like medicine. In the present article we propose a novel methodological approach for generating explanations of the predictions of a generic ML model, given a specific instance for which the prediction has been made, that can tackle both classification and regression tasks. Advantages of the proposed XAI approach include improved fidelity to the original model, the ability to deal with non-linear decision boundaries, and native support to both classification and regression problems

Цель — изучение корреляционных взаимосвязей основных хозяйственно-ценных признаков в конкурсном питомнике овса посевного. Полевые исследования в питомниках конкурсного сортоиспытания проводили в 2011-2013 гг. на мерзлотных таежно-палевых почвах Хангаласского улуса Центральной Якутии. В полевых условиях Хангаласского улуса Республики Саха (Якутия) изучали более 13 фенотипических признаков овса. Анализ взаимосвязей хозяйственно-ценных признаков показал, что в условиях короткого лета Якутии наибольшее влияние на урожайность оказали признаки: число зерен в метелке, масса зерна с метелки, выход зерна с метелки. В засушливый 2012 г. коэффициент корреляции составил 0,81*, а в недостаточно увлажненный, умеренно увлажненный 2011 г. и 2013 г. — 0,78* и 0,44 соответственно, что свидетельствует о надежности отбора по признаку массы зерна с метелки, число зерен в метелке, выход зерна с метелки для засушливого региона. При отборе сортообразцов на урожайность овса посевного следует обратить внимание на признаки: число зерен в метелке и масса зерен с метелки овса посевного.

description: Many physics and engineering applications demand Partial Differential Equations (PDE) property evaluations that are traditionally computed with resource-intensive high-fidelity numerical solvers. Data-driven surrogate models provide an efficient alternative but come with a significant cost of training. Emerging applications would benefit from surrogates with an improved accuracy-cost tradeoff, while studied at scale. Here we present a "physics-enhanced deep-surrogate" ("PEDS") approach towards developing fast surrogate models for complex physical systems, which is described by PDEs. Specifically, a combination of a low-fidelity, explainable physics simulator and a neural network generator is proposed, which is trained end-to-end to globally match the output of an expensive high-fidelity numerical solver. Experiments on three exemplar testcases, diffusion, reaction-diffusion, and electromagnetic scattering models, show that a PEDS surrogate can be up to 3$\times$ more accurate than an ensemble of feedforward neural networks with limited data ($\approx 10^3$ training points), and reduces the training data need by at least a factor of 100 to achieve a target error of 5%. Experiments reveal that PEDS provides a general, data-driven strategy to bridge the gap between a vast array of simplified physical models with corresponding brute-force numerical solvers modeling complex systems, offering accuracy, speed, data efficiency, as well as physical insights into the process.

description: Исследования по изучению влияния трех сроков сева и трех доз минеральных удобрений (без удобрений, N16P16K16 + N30, N16P16K16 + NJ на урожайность и качество однолетних травосмесей, возделываемых в промежуточных посевах, проводили на опытном поле Мордовского НИИСХ — филиале ФГБНУ ФАНЦ Северо-Востока в 2017-2019 гг. на черноземе выщелоченном среднегумусном тяжелосуглинистом. Установлено, что продолжительность вегетационного периода кормовых растений по срокам сева зависела от погодных условий и при уборке на зеленую массу составила: при первом сроке сева — 68-85 дней, при втором — 63-72 дня, при третьем — 53-60 дней. Наибольшую высоту растения имели при первом сроке посева с внесением удобрений в дозе N16P16K16 + N60. Минимальные показатели по высоте отмечены при третьем сроке посева. Среди культур наибольшую высоту имела суданская трава, наименьшую — вико-овсяная смесь. Во все годы исследований максимальная продуктивность растений достигалась при первом сроке сева. Наибольшая урожайность зеленой массы (16,7 т/га) отмечена при возделывании суданской травы в смеси с редькой масличной на фоне N16P16K16 + N60. По вико-овсяной смеси урожайность была на 39,5%, а по суданской траве с горчицей белой на 4,5% ниже. По сбору сухого вещества и кормовых единиц наблюдалась аналогичная ситуация. По содержанию протеина смеси суданской травы с крестоцветными культурами превосходили вико-овсяную смесь на 8-25%, а по жиру — на 31-41%. Количество клетчатки в смесях уменьшалось от первого срока сева к последнему. Экономическая оценка показала, что возделывание однолетних травосмесей после озимой ржи без внесения минеральных удобрений оказалось наиболее рентабельным (в среднем 80%). Наибольшую рентабельность производства (160%) обеспечили посевы суданской травы в смеси с редькой масличной.

description: Isotopic effects in projectile fragmentation at relativistic energies have been studied with the ALADIN forward spectrometer at SIS. Stable and radioactive Sn and La beams with an incident energy of 600 MeV per nucleon have been used in order to explore a wide range of isotopic compositions. Chemical freeze-out temperatures are found to be nearly invariant with respect to the A/Z ratio of the produced spectator sources, consistent with predictions for expanded systems. Consequences for the proposed interpretation of chemical breakup temperatures as representing the limiting temperatures predicted by microscopic models are discussed.

description: Высокое содержание органического вещества — характерный признак черноземных почв, обусловливающий их высокий уровень плодородия. В связи с этим изучался характер изменения содержания и компонентного состава гумуса чернозема обыкновенного Воронежской области при различном сельскохозяйственном использовании. Определяли содержание и состав гумуса, содержание и состав лабильных гумусовых веществ (ЛГВ) методами Тюрина и Пономаревой-Плотниковой. При использовании чернозема обыкновенного в неорошаемом земледелии содержание и запасы гумуса уменьшились по сравнению с многолетней залежью на 3,29% и 71 т/га соответственно. В составе гумуса заметно увеличилось количество гуминовых кислот, отношение СГК:СФК возросло с 1,85 до 2,31. Среди гуминовых кислот (ГК) наиболее устойчива к минерализации фракция ГК-2, и ее доля в составе группы ГК возросла с 65 до 89%. Вовлечение старопахотного чернозема в орошаемое земледелие вызывает изменение его гумусового состояния, непосредственно зависящее от условий использования орошаемой пашни. В кормовом севообороте с многолетними травами содержание гумуса увеличилось с 7,31 до 7,57%, отношение СГК:СФК возросло с 2,31 до 2,48, однако вклад фракции ГК-2 в группу ГК уменьшился и составил 74%. При бессменном возделывании кукурузы содержание гумуса изменилось с 7,31 до 6,93-7,16% и произошла его фульватизация, поэтому отношение СГК:СФК уменьшилось с 2,31 до 1,75-1,90. В пахотных почвах резко уменьшилось содержание лабильных гумусовых веществ (ЛГВ) и азота в их составе. По сравнению с многолетней залежью содержание углерода ЛГВ в неорошаемом черноземе снизилось с 0,911 до 0,036%, а количество азота в ЛГВ — с 0,108 до 0,028%. В орошаемых черноземах содержание углерода и азота ЛГВ составило, соответственно, 0,563 и 0,061% при возделывании многолетних трав и 0,366-0,402 и 0,034-0,035% под бессменной кукурузой.

description: The decoherence induced on a single qubit by its interaction with the environment is studied. The environment is modelled as a scalar two-level boson system that can go through either first order or continuous excited state quantum phase transitions, depending on the values of the control parameters. A mean field method based on the Tamm-Damkoff approximation is worked out in order to understand the observed behaviour of the decoherence. Only the continuous excited state phase transition produces a noticeable effect in the decoherence of the qubit. This is maximal when the system-environment coupling brings the environment to the critical point for the continuous phase transition. In this situation, the decoherence factor (or the fidelity) goes to zero with a finite size scaling power law.
Plant (Asclepias) - insect (Oncopeltus) chemical relationship
Creators: name: Duffey, Sean Stephen
Publisher: name: University of British Columbia
Year: 2011

description: The association of the Large Milkweed Bug, Oncopeltus fasciatus Dallas, with, a potentially poisonous Asclepiad, Asclepias, has been investigated to determine the fate of sequestered cardiac glycosides in this insect and to investigate the possibility that these compounds and/or odorous and volatile alkyl secretions of this insect may be serving as (an) anti-predator device(s). Nineteen species of Asclepias from diverse parts of North America have been shown to contain cardiac glycosides. Evidence is also given that Oncopeltus plus several other species of brightly coloured Coleopterans and Hemipterans, which are associated with Asclepias as a food-host, contain cardenolides which could function as the chemical basis for a Mullerian mimicry complex. The large quantities of polar cardiac glycosides sequestered by Oncopeltus fasciatus (approximately 111 micrograms) from the seeds of Asclepias syriaca were found to be concentrated in a complex of dorso-lateral abdominal and thoracic secretory glands. Various parameters of the uptake and entry of the natural cardiac glycosides of Asclepias syriaca and unnatural isotopic cardiac glycosides into the dorso-lateral glands were examined. The high levels of polar glycosides in Oncopeltus is also related to other aspects of the insect's physiology and the cardenolide composition of the food-host. The literature cites that lipid cardenolides are more emetic to birds than are the polar glycosides: therefore, the high levels of polar glycosides in this Hemipteran feeding on the above plant could make it non-emetic. Oncopeltus fasciatus was shown to be aposematic to chickens, turtles, lizards and starlings because of the volatile secretions of the ventral metathoracic glands. Frogs and toads did not consider this insect to be aposematic. The cardiac glycosides that had been sequestered from the seeds of this northern Asclepiad by Oncopeltus were not shown to be effective in causing rejection by the above predators in laboratory conditions. The predation studies on Oncopeltus suggest that the responses of various predators to a complex of glycoside containing mimics are not equivalent. This study also shows that along with predator responses being a critical feature in a palatability spectrum, the insect's physiology and its behavioural association with the plant are poignant aspects of the insect's potential to be unpalatable.

description: We compute the cotorsion product of the mod 2 cohomology of spinor group spin(n), which is the E_2-term of the Rothenberg-Steenrod spectral sequence for the mod 2 cohomology of the classifying space of the spinor group spin(n). As a consequence of this computation, we show the non-collapsing of the Rothenberg-Steenrod spectral sequence for n > 16.

description: Республика Беларусь является активным экспортером на продовольственном рынке Российской Федерации, что сдерживает предпринимательскую активность отечественных товаропроизводителей. Поэтому целью исследования был анализ тенденций и потенциала развития сельского хозяйства в Республике Беларусь как предпосылок для дальнейшего поступления излишков производимого в стране продовольствия на российский рынок. В процессе работы применялся экономико-статистический метод исследования с использованием данных Национального статистического комитета Республики Беларусь за период с 2012 по 2019 гг. Проведенный анализ динамики структурных изменений в сельском хозяйстве республики позволяет сделать вывод о сохранении достаточно высокого уровня производства основных продуктов сельского хозяйства в расчете на душу населения. За прошедший период произошел рост численности поголовья крупного рогатого скота, в том числе коров, а также молодняка птицы, что позволило увеличить размеры посевных площадей и особенно кормовых культур на 30%. В стране поддерживается высокий уровень экспортного потенциала, в том числе значительный удельный вес вывоза продуктов животного происхождения в Россию. Несмотря на успешное в целом развитие отрасли сельского хозяйства, в республике наблюдаются проблемы, связанные с сокращением численности занятых в отрасли на 18,2%, в том числе в сельскохозяйственных организациях — на 20,3%, и изменением их демографических характеристик, при недостаточном уровне технического оснащения производства. Однако исследования позволяют сделать вывод о возможном дальнейшем росте масштабов присутствия продукции сельского хозяйства Республики Беларусь на российском продовольственном рынке, что, в первую очередь, связано со снижением доходов населения и более низкими розничными ценами на ввозимую продукцию.
Combinatorics of the Springer correspondence for classical Lie algebras and their duals in characteristic 2

description: We give a combinatorial description of the Springer correspondence for classical Lie algebras $\mathfrak{g}$ of type $B,C$ or $D$ and their duals $\mathfrak{g}^*$ in characteristic 2. The combinatorics used here is of the same kind as those appearing in the description of (generalized) Springer correspondence for unipotent case of classical groups $G$ by Lusztig in odd characteristic and by Lusztig and Spaltentstein in characteristic 2. It is very nice that this combinatorics gives a unified description for (generalized) Springer correspondences of classical groups in all cases, namely, in $G$, $\mathfrak{g}$ and $\mathfrak{g}^*$ in all characteristics. Moreover, it gives rise to close formulas for computing the correspondences.

description: This paper treats the existence of positive solutions of $-Δu + V(x) u = λf(u)$ in $\mathbb{R}^N$. Here $N \geq 1$, $λ> 0$ is a parameter and $f(u)$ satisfies conditions only in a neighborhood of $u=0$. We shall show the existence of positive solutions with potential of trapping type or $\mathcal{G}$-symmetric potential where $\mathcal{G} \subset O(N)$. Our results extend previous results as well as we also study the asymptotic behavior of a family $(u_λ)_{λ\geq λ_0}$ of positive solutions as $λ\to \infty$.

The intertidal ecology of Tasmania
Creators: name: Guiler, ER
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis represents the results of five years' work on various aspects of the intertidal ecology of Tasmania. Most of the study of the features of our intertidal region has been carried out in South Tasmania but visits have been made to the East, West and North Coasts of the island. The study is not yet complete as a work of this nature will take many years. It is considered, however, that the present stage of the investigation as presented in this thesis, is sufficiently advanced to make it worth recording. For convenience in presentation, the thesis has been divided into a series of parts which are all inter-related. There is a certain inevitable overlap of the material contained in the various parts but the discussions at the end of the parts is brief to avoid repetition in Parts 11, 12 and 15. The major ecological problem in Tasmania is taxonomic. This is not discussed in the text but a few words here may suffice to illustrate the difficulties. There are only three check lists of invertebrate animals available to workers in Tasmania. One of these deals with the Molluscs (MEW, 1921 and 1923) and the other two have been prepared as supplements to this investigation. The two groups listed are the Porifera and the Crustacea, and it has been found necessary to revise a list of the algae. Besides the lack of complete lists, much of the fauna has never been described and until such time as experts have worked on the various groups, it is impossible to proceed to community and population studies. For this reason the work has been largely confined to the major features of various ecological habitats rather than to detailed population studies. Some of this work has been published and other parts are in press. The published material has appeared in Papers of the Royal Society of Tasmania, 1949, 1950 and 1951. Certain other features have been mentioned in lectures delivered before the Royal Society of Tasmania (5th July, 1949), the Tasmanian Field Naturalists Club (15th March, 1951) and the Australian and New Zealand Association for the Advancement of Science (25th May, 1951).
The hydrodynamics of the supernova remnant Cas A: The influence of the progenitor evolution on the velocity structure and clumping

description: There are large differences in the proposed progenitor models for the Cas A SNR. One of these differences is the presence or absence of a Wolf-Rayet (WR) phase of the progenitor star. The mass loss history of the progenitor star strongly affects the shape of the Supernova remnant (SNR). In this paper we investigate whether the progenitor star of Cas A had a WR phase or not and how long it may have lasted. We performed two-dimensional multi-species hydrodynamical simulations of the CSM around the progenitor star for several WR life times, each followed by the interaction of the supernova ejecta with the CSM. We then looked at the influence of the length of the WR phase and compared the results of the simulations with the observations of Cas A. The difference in the structure of the CSM, for models with different WR life times, has a strong impact on the resulting SNR. With an increasing WR life time the reverse shock velocity of the SNR decreases and the range of observed velocities in the shocked material increases. Furthermore, if a WR phase occurs, the remainders of the WR shell will be visible in the resulting SNR. Comparing our results with the observations suggests that the progenitor star of Cas A did not have a WR phase. We also find that the quasi-stationary flocculi (QSF) in Cas A are not consistent with the clumps from a WR shell that have been shocked and accelerated by the interaction with the SN ejecta. We can also conclude that for a SN explosion taking place in a CSM that is shaped by the wind during a short < 15000 yr WR phase, the clumps from the WR shell will be visible inside the SNR.

The targum (1939:May 3 - 1939:May 20)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1939

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.
Spatial Structure and Information Transfer in Visual Networks

description: In human and animal groups, social interactions often rely on the transmission of information via visual observation of the behavior of others. These visual interactions are governed by the laws of physics and sensory limits. Individuals appear smaller when far away and thus become harder to detect visually, while close by neighbors tend to occlude large areas of the visual field and block out interactions with individuals behind them. Here, we systematically study the effect of a group’s spatial structure, its density as well as polarization and aspect ratio of the physical bodies, on the properties of static visual interaction networks. In such a network individuals are connected if they can see each other as opposed to other interaction models such as metric or topological networks that omit these limitations due to the individual’s physical bodies. We find that structural parameters of the visual networks and especially their dependence on spatial group density are fundamentally different from the two other types. This results in characteristic deviations in information spreading which we study via the dynamics of two generic SIR-type models of social contagion on static visual and metric networks. We expect our work to have implications for the study of animal groups, where it could inform the study of functional benefits of different macroscopic states. It may also be applicable to the construction of robotic swarms communicating via vision or for understanding the spread of panics in human crowds.
