description: The large-scale organization of complex networks, both natural and artificial, has shown the existence of highly heterogeneous patterns of organization. Such patterns typically involve scale-free degree distributions and small world, modular architectures. One example is provided by chemical reaction networks, such as the metabolic pathways. The chemical reactions of the Earth's atmosphere have also been shown to give rise to a scale-free network. Here we present novel data analysis on the structure of several astrophysical networks including the chemistry of the planetary atmospheres and the interstellar medium. Our work reveals that Earth's atmosphere displays a hierarchical organization, close to the one observed in cellular webs. Instead, the other astrophysical reaction networks reveal a much simpler pattern consistent with an equilibrium state. The implications for large-scale regulation of the planetary dynamics are outlined.

Year: 2023

description: I. THE PROBLEMThe history of cooperative movement has existed more than a century since it was orderly organized in 1844 by a group of weavers in Rochdale, England. Since then it has become a social and economic movement spreading all over the world, including Soviet Russia. The cooperative type of organization applies to many fields of business from retailing to manufacturing. To private businessmen the cooperative movement is a great challenge with its ever-growing activities along many lines in lower prices along with better services; to the enthusiastic social reformers it is a powerful revolution for a better economic order.

description: We present an updated analysis of the gamma-ray flux from the directions of classical dwarf spheroidal galaxies, deriving new constraints on WIMP dark matter (DM) annihilation using a decade of Fermi-LAT data. Among the major novelties, we infer the dwarfs' J-factors by including new observations without imposing any a priori parametric profile for the DM distribution. While statistically compatible with results obtained from more conventional parameterisations, this procedure reduces the theoretical bias imposed on the data. Furthermore, we retain the full data-driven shape of the J-factors' empirical probability distributions when setting limits on DM, without imposing log-normality as is typically done. In conjunction with the data-driven J-factors, we use a new method for estimating the probability distribution function of the astrophysical background at the dwarf position, fully profiling over background uncertainties. We show that, for most classical dwarfs, the background systematic uncertainty dominates over the uncertainty on their J-factors. Raw distributions of J- and D-factors (the latter being the analogous of J-factors for decaying DM) are available upon request.

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The lackadaisical quantum walk is a discrete-time, coined quantum walk on a graph with a weighted self-loop at each vertex. It uses a generalized Grover coin and the flip-flop shift, which makes it equivalent to Szegedy's quantum Markov chain. It has been shown that a lackadaisical quantum walk can improve spatial search on the complete graph, discrete torus, cycle, and regular complete bipartite graph. In this paper, we observe that these are all vertex-transitive graphs, and when there is a unique marked vertex, the optimal weight of the self-loop equals the degree of the loopless graph divided by the total number of vertices. We propose that this holds for all vertex-transitive graphs with a unique marked vertex. We present a number of numerical simulations supporting this hypothesis, including search on periodic cubic lattices of arbitrary dimension, strongly regular graphs, Johnson graphs, and the hypercube.

description: A laboratory experiment was carried out to see the distribution of sorbed potassium (K) in Old Brahmaputra Floodplain and Madhupur Terrace soils and its subsequent release behaviour for getting an idea on K fertility of these two soils. For sorption, four different concentrations 0, 10, 20 and 30 mg K L-1 were added and kept for 15 days. After the allocated time, one sample of the treated soils was repeatedly extracted with 1N NH40Ac solution to see the K release capacity and another sample was sequentially extracted with distilled water, 1N NH40Ac and H2SO4 for water soluble, exchangeable and non-exchangeable forms of K. The sorption of K increased progressively with increasing K concentrations of the solution. The flood plain soil sorbed higher amount of K compared to terrace soil. The terrace soils from Madhupur farm sorbed K mostly in exchangeable form whereas the flood plain soil from BAU farm sorbed mostly in non-exchangeable form. About 33-41% and 36-62% of added K were released by the first extraction for BAU farm and Madhupur soils respectively, but in following extractions the release of K from BAU farm soil was almost equal or higher than Madhupur soil. The Elovich equation showed a higher rate of K release from Madhupur soil than from BAU farm soil.
title: Trends in polychlorinated biphenyl residues in three British predatory bird species.

description: Liver total PCBs have been monitored in British sparrowhawks Accipiter nisus, kestrels Falco tinnunculus and herons Ardea cinerea since the 1960s. Concentrations do not appear to have declined in sparrowhawks or kestrels, despite bans and restrictions on PCB manufacture and disposal, but residues vary markedly between individuals which may obscure long-term trends. In this study measurements were made of PCB liver concentrations in sparrowhawks, kestrels and herons collected from locations throughout Britain between 1992 and 1997: (i) to determine the major causes of intraspecies variation in liver concentrations, and (ii) to characterise and quantify liver concentrations of individual congeners and their associated toxicity. The long-term PCB data were also reanalysed to determine if there was evidence of declines in liver PCBs once intra-species variation was accounted for.

Body condition, and to a lesser extent age and sex, affected liver PCB congener, sum PCB and Toxic Equivalent Quotient (TEQ) concentrations. Concentrations were higher in starved than in non-starved birds, largely because of remobilisation of residues (sparrowhawks and herons) and starvation-induced liver wastage (all species). Adults generally had higher liver PCB concentrations than first-year birds, and male sparrowhawks and kestrels lower concentrations than females, although this varied with body condition. Congener profiles were similar across species, and concentrations of individual congeners were primarily determined by their potential to be metabolised. PCBs 138, 153, 180 and 170 accounted for up to 76% £PCB concentrations. Non-ortho, coplanar PCBs (primarily 118 and 169) were mostly detected in starved birds. Liver TEQ concentrations were below Lowest Observable Effect Concentrations. Intra-year variation in body condition obscured a decline in liver PCB concentrations in sparrowhawks, but liver PCB concentrations have not declined in kestrels.

The results obtained provide insights into which factors should be taken into account when using tissue concentrations in biota to monitor changes in environmental exposure to contaminants.
A diagnosis of explicit symmetry breaking in the tight-binding constructions for symmetry-protected topological systems

description: It has been well established that for symmetry protected topological systems, the non-trivial topology prevents a real space representation using exponentially localized Wannier wavefunctions (WFs) in all directions, unless the protecting symmetry is sacrificed as an on-site transformation. This makes it challenging to determine the symmetry of various physical observables represented using such WFs. In this work, we propose a practical method for overcoming such challenges using the Kane-Mele model as a concrete example. We present a systematic procedure for diagnosing the symmetry of any observables, as well as a method for constructing symmetric operators up to arbitrary truncation accuracy.

title: "What Kind of Animal is the Nazi Beast?": Representations of Perpetrators in Narratives of the Holocaust.
Creators: name: Pettitt, Joanne
Publisher: name: University of Kent
Year: 2016

description: This project seeks to explore representations of Holocaust perpetrators in literature. Such texts, often rather controversially, seek to undo the myth of “pure evil” that surrounds the Holocaust and to reconstruct the perpetrator in more “human” terms. Accordingly, significant questions of “how” and “why” are centralised and explored, providing fertile ground for examinations of the intersections between ethics, literature and history, and enabling ongoing discussions about the characteristics and obligations of perpetrator literature as a whole. Of central concern, these humanising discourses place emphasis on the contextual or situational factors that led up to the genocide. Following these issues through to their logical conclusion, this project takes the question of determinism seriously. This is not to suggest that it disavows individual responsibility, merely that it engages fully with the philosophical problems that are invoked through allusions to external influences, especially as they relate to ideas of contingency. A significant consequence of these discussions is the impact that they have on the reader. That is because, since situational aspects are featured so heavily in these narratives, questions are raised about his or her own capacity for wrongdoing. Consequently, the reader is drawn into the narrative as a potential perpetrator. The tensions that this creates constitutes the second major focus of this work. Ultimately, I hope to expose the challenges that face the reader when they encounter perpetrator narratives, and the ways in which these tensions impact upon our understandings of these figures, and of the Holocaust more generally. In order to provide a more comprehensive overview this project makes use of a large number (in excess of sixty) primary sources, examining both fictional and non-fictional accounts. My aim is not to offer close literary analyses of each of the texts under consideration but, rather, to trace paradigms across the full spectrum of perpetrator literature. In this way, I hope to contribute to the growing body of literature that engages with this topic.

description: A pot experiment was conducted in the net-house of the Department of Soil Science, Bangladesh Agricultural University, Mymensingh during January to May, 2007 to investigate the effects of six selected Bradyrhizobium strains and urea-N on the growth and yield of soybean. There were eight treatments such as To: control, Ti: Urea @ 40 kg N had, T2: BAU 101, T3: BAU 107, T4: BAU 118, T5: BAU 145, Ts: BAU 150 and T7: TAL 102. The experiment was laid out in a Completely Randomized Design (CRD) having four replications. Phosphorus, potassium and sulphur were applied as basal dose from TSP, MOP and gypsum @ 40 kg P ha-1, 60 kg K ha-1 and 15 kg S had, respectively. Bradyrhizobium inoculation significantly increased the nodule number, nodule dry weight, root weight, shoot weight, N content and N uptake by plant at 33, 60 and 98 days after sowing over uninoculated control. Bradyrhizobium inoculation also significantly increased pod and seed number per plant, 100- seed weight, grain and stover yield of soybean over control. The effects of the strain BAU 107 was found most promising in growing soybean crop.
Cirrus models for local and high z SCUBA galaxies

description: We present a model for the UV to submillimeter emission from stars embedded in the general interstellar dust in galaxies (the 'infrared cirrus' component). Such emission is characterized by relatively low optical depths of dust and by cool (< 30 K) dust temperatures. The model incorporates the stellar population synthesis model of Bruzual & Charlot and the dust model of Siebenmorgen & Krugel which includes the effects of small grains/PAHs. We apply the model to fit the optical to submillimeter spectral energy distributions (SEDs) of nearby galaxies which are dominated by cirrus emission and find that our simple model is quite adequate to explain the observed SEDs. We also, more controversially, apply this cirrus model to the SEDs of high redshift sources detected in blank field submillimeter surveys with SCUBA. Surprisingly, an excellent fit is found for many of these sources, with typical values for the optical depth A_V and the surface brightness of the stellar radiation field psi being only a factor 2-3 higher than for nearby galaxies. This increase is not unreasonable given the expected evolution of dust optical depth in currently favoured star-formation history models. We conclude that the tendency to interpret the high-z SCUBA galaxies as very highly obscured starbursts may be premature and that these galaxies may be more closely linked to optically selected high redshift galaxies than previously assumed.

description: Collisionless shocks heat electrons in the solar wind, interstellar blast waves, and hot gas permeating galaxy clusters. How much shock heating goes to electrons instead of ions, and what plasma physics controls electron heating? We simulate 2-D perpendicular shocks with a fully kinetic particle-in-cell code. For magnetosonic Mach number $\mathcal{M}_\mathrm{ms} \sim 1$-$10$ and plasma beta $β_\mathrm{p} \lesssim 4$, the post-shock electron/ion temperature ratio $T_\mathrm{e}/T_\mathrm{i}$ decreases from $1$ to $0.1$ with increasing $\mathcal{M}_\mathrm{ms}$. In a representative $\mathcal{M}_\mathrm{ms}=3.1$, $β_\mathrm{p}=0.25$ shock, electrons heat above adiabatic compression in two steps: ion-scale $E_\parallel = \vec{E} \cdot \hat{b}$ accelerates electrons into streams along $\vec{B}$, which then relax via two-stream-like instability. The $\vec{B}$-parallel heating is mostly induced by waves; $\vec{B}$-perpendicular heating is mostly adiabatic compression by quasi-static fields.

description: This study examines the following question: could the personification of plants—relaying human characteristics to a non-human plant—increase pro-environmental behaviour? Through personifying plants, we believe that participants in our experiment can better relate to plants, therefore increasing their pro-environmental behaviours. Such findings will be important to the field since it could be used to personify greater aspects of nature (such as parks and forests) to elicit more pro-environmental behaviour. Our experiment was conducted at the CIRS building at the University of British Columbia. Data was observed of students and staff passing through the building during our observation period. Three conditions were observed in our experiment: 1) a personified plant, 2) a plant with scientific information, and 3) a plant with instructions for care. Measurement of pro-environmental behaviour is collected through the use of fertilizer distribution for each plant. Increased amounts of fertilizer represents more pro-environmental interaction between the plants and participants. Our finding suggests that personified plants received the most pro-environmental interaction, followed by plants with scientific information, and lastly plants with care instructions only.

description: An experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University (BAU), Mymensingh during February to May 2005 with a view to studying the effect of variety and sulphur on the seed yield, oil content and protein content of sesame. The experiment consisted of three sesame varieties (BINA Ti1-1, BARI Ti1-2 and Local) and four sulphur levels (0, 9, 18 and 27 kg S ha-1). The experiment was laid out in a randomized complete block design with three replications. The result showed significant variations among the varieties for all the studied crop characters. The highest seed yield, stover yield, oil content and harvest index was recoded with BINA Ti1-1 and the lowest performance was with local variety. Sulphur fertilization showed significant influence on the studied plant characters except length of capsule, 1000-seed weight and stover yield. The highest seed yield, oil content and protein content were achieved from the application of 27 kg S ha -I which was not significantly different from that of 18 kg S ha.1. On overall consideration, the best performance with respect to seed yield, oil and protein content was obtained from the combination of BINA Ti1-1 and application of 18 kg S ha-1.

description: We consider the Einstein-Yang-Mills Lagrangian in a (4+n)-dimensional space-time. Assuming the matter and metric fields to be independent of the n extra coordinates, a spherical symmetric Ansatz for the fields leads to a set of coupled ordinary differential equations. We find that for n > 1 only solutions with either one non-zero Higgs field or with all Higgs fields constant exist. We construct the analytic solutions which fulfill this conditions for arbitrary n, namely the Einstein-Maxwell-dilaton solutions. We also present generic solutions of the effective 4-dimensional Einstein-Yang-Mills-Higgs-dilaton model, which possesses n Higgs triplets coupled in a specific way to n independent dilaton fields. These solutions are the abelian Einstein-Maxwell- dilaton solutions and analytic non-abelian solutions, which have diverging Higgs fields. In addition, we construct numerically asymptotically flat and finite energy solutions for n=2.

description: This paper reports positive detections of surface differential rotation on two rapidly rotating cool stars at several epochs, by using stellar surface features (both cool spots and magnetic regions) as tracers of the large scale latitudinal shear that distorts the convective envelope in this type of stars. We also report definite evidence that this differential rotation is different when estimated from cool spots or magnetic regions, and that it undergoes temporal fluctuations of potentially large amplitude on a time scale of a few years. We consider these results as further evidence that the dynamo processes operating in these stars are distributed throughout the convective zone rather than being confined at its base as in the Sun. By comparing our observations with two very simple models of the differential rotation within the convective zone, we obtain evidence that the internal rotation velocity field of the stars we investigated is not like that of the Sun, and may resemble that we expect for rapid rotators. We speculate that the changes in differential rotation result from the dynamo processes (and from the underlying magnetic cycle) that periodically converts magnetic energy into kinetic energy and vice versa. We emphasise that the technique outlined in this paper corresponds to the first practical method for investigating the large scale rotation velocity field within convective zones of cool active stars, and offers several advantages over asteroseismology for this particular purpose and this specific stellar class.

description: We develop a unified theoretical framework for the efficient description of multiphoton states generated and propagating in loop-based optical networks which contain nonlinear elements. These active optical components are modeled as nonlinear media, resembling a two-mode squeezer. First, such nonlinear components can be seeded to manipulate quantum states of light, as such enabling photon addition protocols. And, second, they can function as an amplifying medium for quantum light. To prove the practical importance of our approach, the impact of multiple round trips is analyzed for states propagating in experimentally relevant loop configurations of networks, such as time-multiplexed driven quantum walks and iterative photon-number state generation protocols. Our method not only enables us to model such complex systems but also allows us to propose alternative setups that overcome previous limitations. To characterize the systems under study, we provide exact expressions for fidelities with target states, success probabilities of heralding-type measurements, and correlations between optical modes, including many realistic imperfections. Moreover, we provide an easily implementable numerical approach by devising a vector-type representation of photonic states, measurement operators, and passive and active processes.

description: Polarisation observables constitute a powerful tool for establishing the production mechanism of the eta meson and for infering the presence of higher partial waves in the final system. Measurements of the proton analysing power for the p(pol)p-->ppeta reaction have been performed by the COSY-11 group at three different excess energies: Q=10, 37 and 40 MeV. Data at Q=40 MeV indicate that the eta meson is probably produced in partial waves higher than s wave.

description: Nodulation, growth, N content and its uptake by lentil grown on silt loam soil were examined during November 2006 to May 2007. Seeds were inoculategi with four rhizobial strains viz. strain-638, strain- 640, strain-2, mixed strains (Strain 638, 640 and 2) and sown in pots following completely randomized design with four replications. Urea @ 45 kg ha-1 and a control treatment were included to compare the effectiveness of the rhizobial strains. The results indicated that rhizobia significantly influenced most of the parameters studied except leaf area, pod number and dry matter weight. The highest value for all the parameters was recorded from plants inoculated with strain-638. A maximum to 77% increased nodulation over control was calculated from plants inoculated with the same strain. Different varieties had significant influence on all the parameters except leaf area. The highest value for most of the parameters was found in Binamasur-1 except plant height, nodule dry weight and stover N content which were obtained from Binamasur-3. Interaction effects of different rhizobial strains and varieties also showed significant variation only in stover N content and its uptake by lentil. Positive correlations were observed between dry matter weight, grain N content, nodule number and plant height. The overall results suggested that rhizobial strains can be used for producing higher yield without any nitrogenous fertilizer in lentil and Binamasur-1 can be cultivated inoculating with strain-638 for the maximum nodulation, N fixation and dry matter production.

description: The so-called Dixon system is often cited as an example of a two-dimensional (continuous) dynamical system that exhibits chaotic behaviour, if its two parameters take their value in a certain domain. We provide first a rigorous proof that there is no chaos in Dixon's system. Then we perform a complete bifurcation analysis of the system showing that the parameter space can be decomposed into sixteen different regions in each of which the system exhibits qualitatively the same behaviour. In particular, we prove that in some regions two elliptic sectors with infinitely many homoclinic orbits exist.

description: We review the homotopy algebraic perspective on perturbative quantum field theory: classical field theories correspond to homotopy algebras such as $A_\infty$- and $L_\infty$-algebras. Furthermore, their scattering amplitudes are encoded in minimal models of these homotopy algebras at tree level and their quantum relatives at loop level. The translation between Lagrangian field theories and homotopy algebras is provided by the Batalin--Vilkovisky formalism. The minimal models are computed recursively using the homological perturbation lemma, which induces useful recursion relations for the computation of scattering amplitudes. After explaining how the homological perturbation lemma produces the usual Feynman diagram expansion, we use our techniques to verify an identity for the Berends--Giele currents which implies the Kleiss--Kuijf relations.

Subjects: Crop Production/Industries

description: The purpose of this paper is to deeply analyse the changes caused by the planting structure of grain crops from the supply perspective between 1993 and 2016.First, the paper introduces the background and progress of the pricing mechanism reform of grain crops. Then, the paper establishes the supply response models of rice, wheat, corn, and soybean based on the Nerlove model. It uses data from 1993 to 2016 to analyse farmers supply responses to the changes in the main influencing factors from three levels: the whole country, the main production areas, and northeast China.Findings are that the short term and long term supply elasticities of the sown area to the prices for rice and soybeans are far less than corn and soybeans in both the main production areas and northeast China. Market price supports for rice should be quickly reformed because of the price marketization of corn and soybeans, or else the problems that happened with corn may happen with rice in northeast China.

description: Argentina is the fourth highest consumer of sweetened drinks, and the first consumer of soda in the world. In this paper we estimate a quadratic almost ideal demand system (QUAIDS) to explore demand for a number of sweetened and unsweetened beverages in Argentina. We use two household surveys: the last one available, performed in 2012-2013, and the previous one, carried over in 2004-2005. We explore expenditure shares and own and cross price elasticities. These results can shed light on a discussion that was held in 2017 in Congress towards the design of a tax reform on sweet beverages that will affect consumers, farmers, and the retail and food industries. Our results support the notion that a tax applied to highly sweetened beverages will affect consumption: for every 1% increase in price there will be a 1.32% drop in quantity purchased. In addition,we find that for every 1% price increase in highly sweetened beverages there will be a 1.12% increase in the amount of dairy beverages purchased. Acknowledgement :
