description: Context: The Large Magellanic Cloud (LMC) is to date the only normal external galaxy that has been detected in high-energy gamma rays. High-energy gamma rays trace particle acceleration processes and gamma-ray observations allow the nature and sites of acceleration to be studied. Aims: We characterise the distribution and sources of cosmic rays in the LMC from analysis of gamma-ray observations. Methods: We analyse 11 months of continuous sky-survey observations obtained with the Large Area Telescope aboard the Fermi Gamma-Ray Space Telescope and compare it to tracers of the interstellar medium and models of the gamma-ray sources in the LMC. Results: The LMC is detected at 33 sigma significance. The integrated >100 MeV photon flux of the LMC amounts to (2.6 +/- 0.2) * 10^-7 ph/cm2/s which corresponds to an energy flux of (1.6 +/- 0.1) * 10^-10 erg/cm2/s, with additional systematic uncertainties of ~16%. The analysis reveals the massive star forming region 30 Doradus as a bright source of gamma-ray emission in the LMC in addition to fainter emission regions found in the northern part of the galaxy. The gamma-ray emission from the LMC shows very little correlation with gas density and is rather correlated to tracers of massive star forming regions. The close confinement of gamma-ray emission to star forming regions suggests a relatively short GeV cosmic-ray proton diffusion length. Conclusions: The close correlation between cosmic-ray density and massive star tracers supports the idea that cosmic rays are accelerated in massive star forming regions as a result of the large amounts of kinetic energy that are input by the stellar winds and supernova explosions of massive stars into the interstellar medium.

description: Este trabajo se propone explorar la influencia de un militarismo específico, el progresista, en la experiencia de uno de los grupos más emblemáticos de la Nueva Izquierda, el uruguayo Movimiento de Liberación Nacional Tupamaros, así como del Frente Amplio en el mismo país. Sugerimos que a partir del episodio del pre-golpe de febrero de 1973 se puede apreciar la disponibilidad de dicha agrupación para converger con los militares en una experiencia del tipo Velasco Alvarado en Perú.

description: Most geophysical inverse problems are nonlinear and rely upon numerical forward solvers involving discretization and simplified representations of the underlying physics. As a result, forward modeling errors are inevitable. In practice, such model errors tend to be either completely ignored, which leads to biased and over-confident inversion results, or only partly taken into account using restrictive Gaussian assumptions. Here, we rely on deep generative neural networks to learn problem-specific low-dimensional probabilistic representations of the discrepancy between high-fidelity and low-fidelity forward solvers. These representations are then used to probabilistically invert for the model error jointly with the target geophysical property field, using the computationally-cheap, low-fidelity forward solver. To this end, we combine a Markov-chain-Monte-Carlo (MCMC) inversion algorithm with a trained convolutional neural network of the spatial generative adversarial network (SGAN) type, whereby at each MCMC step, the simulated low-fidelity forward response is corrected using a proposed model-error realization. Considering the crosshole ground-penetrating radar traveltime tomography inverse problem, we train SGAN networks on traveltime discrepancy images between: (1) curved-ray (high fidelity) and straight-ray (low fidelity) forward solvers; and (2) finite-difference-time-domain (high fidelity) and straight-ray (low fidelity) forward solvers. We demonstrate that the SGAN is able to learn the spatial statistics of the model error and that suitable representations of both the subsurface model and model error can be recovered by MCMC. In comparison with inversion results obtained when model errors are either ignored or approximated by a Gaussian distribution, we find that our method has lower posterior parameter bias and better explains the observed traveltime data.[...]

description: We apply the concept of subset seeds proposed in [1] to similarity search in protein sequences. The main question studied is the design of efficient seed alphabets to construct seeds with optimal sensitivity/selectivity trade-offs. We propose several different design methods and use them to construct several alphabets. We then perform a comparative analysis of seeds built over those alphabets and compare them with the standard BLASTP seeding method [2], [3], as well as with the family of vector seeds proposed in [4]. While the formalism of subset seeds is less expressive (but less costly to implement) than the cumulative principle used in BLASTP and vector seeds, our seeds show a similar or even better performance than BLASTP on Bernoulli models of proteins compatible with the common BLOSUM62 matrix. Finally, we perform a large-scale benchmarking of our seeds against several main databases of protein alignments. Here again, the results show a comparable or better performance of our seeds vs. BLASTP.

description: Erdős and Simonovits asked the following question: For an integer $r\geq 2$ and a family of non-bipartite graphs $\mathcal{H}$, determine the infimum of $α$ such that any $\mathcal{H}$-free $n$-vertex graph with minimum degree at least $αn$ has chromatic number at most $r$. We answer this question for $r=2$ and any family consisting of odd cycles. Let ${\mathcal C}$ be a family of odd cycles in which $C_{2\ell+1}$ is the shortest odd cycle not in ${\mathcal C}$ and $C_{2k+1}$ is the longest odd cycle in ${\mathcal C}$, we show that if $G$ is an $n$-vertex ${\mathcal C}$-free graph with $n\ge 1000k^{8}$ and $δ(G)>\max\{ n/(2(2\ell+1)), 2n/(2k+3)\}$, then $G$ is bipartite. Moreover, the bound of the minimum degree is tight.

description: We study thermoelectric properties of inhomogeneous nanogranular materials for weak tunneling conductance between the grains, g_t < 1. We calculate the thermopower and figure of merit taking into account the shift of the chemical potential and the asymmetry of the density of states in the vicinity of the Fermi surface. We show that the weak coupling between the grains leads to a high thermopower and low thermal conductivity resulting in relatively high values of the figure of merit on the order of one. We estimate the temperature at which the figure of merit has its maximum value for two- and three-dimensional samples. Our results are applicable for many emerging materials, including artificially self-assembled nanoparticle arrays.

Dabei wird die schriftliche Niederlegung eigener Erfahrungen sowie innovativer Vorschläge zur Gestaltung pädagogischer Prozesse ergänzt durch die öffentliche (Vor-)Lesung für ein Fachpublikum praktisch tätiger Pädagog*innen in großangelegten zentralen Weiterbildungsveranstaltungen. Durch einen zentralistisch organisierten fachlichen Selektionsprozess gelangten zwischen 1955 und 1989 über die Pädagogischen Kreis- und Bezirkskabinette ca. 9500 ‚erfolgreiche‘ Lesungen bis zur Popularisierung und danach in die Pädagogische Zentralbibliothek im Haus des Lehrers Berlin. Der Bestand, der Lesungen aller Unterrichtsfächer ebenso umfasst wie jene zu allgemeinpädagogischen bzw. psychologischen Fragen, ist bis heute vollumfänglich erhalten. [...] Mit diesem Beitrag soll ein erster Schritt zur Analyse dieses in höchstem Maße originellen Quellenmaterials unternommen werden, indem zunächst das Format sowie dessen Entwicklung im Rahmen der DDR-Bildungspolitik kontextualisiert wird. Weiterhin werden die Kriterien, die an erfolgreiche Lesungen angelegt wurden, sowie der überlieferte Schriftverkehr im Kontext der Begutachtung einer ersten Betrachtung unterzogen, um hernach das Maß der administrativen sowie der bildungspolitischen Lenkung zum Verfassen und zur inhaltlichen Gestaltung zu umreißen.

description: We introduce and study pawn games, a class of two-player zero-sum turn-based graph games. A turn-based graph game proceeds by placing a token on an initial vertex, and whoever controls the vertex on which the token is located, chooses its next location. This leads to a path in the graph, which determines the winner. Traditionally, the control of vertices is predetermined and fixed. The novelty of pawn games is that control of vertices changes dynamically throughout the game as follows. Each vertex of a pawn game is owned by a pawn. In each turn, the pawns are partitioned between the two players, and the player who controls the pawn that owns the vertex on which the token is located, chooses the next location of the token. Control of pawns changes dynamically throughout the game according to a fixed mechanism. Specifically, we define several grabbing-based mechanisms in which control of at most one pawn transfers at the end of each turn. We study the complexity of solving pawn games, where we focus on reachability objectives and parameterize the problem by the mechanism that is being used and by restrictions on pawn ownership of vertices. On the positive side, even though pawn games are exponentially-succinct turn-based games, we identify several natural classes that can be solved in PTIME. On the negative side, we identify several EXPTIME-complete classes, where our hardness proofs are based on a new class of games called Lock & Key games, which may be of independent interest.

description: Mars exploration motivates the search for extraterrestrial life, the development of space technologies, and the design of human missions and habitations. Here we seek new insights and pose unresolved questions relating to the natural history of Mars, habitability, robotic and human exploration, planetary protection, and the impacts on human society. Key observations and findings include:(1)high escape rates of early Mars' atmosphere, including loss of water, impact present-day habitability;(2)putative fossils on Mars will likely be ambiguous biomarkers for life;(3)microbial contamination resulting from human habitation is unavoidable;(4)based on Mars' current planetary protection category, robotic payload(s) should characterize the local martian environment for any life-forms prior to human habitation. Some of the outstanding questions are:(1)which interpretation of the hemispheric dichotomy of the planet is correct;(2)to what degree did deep-penetrating faults transport subsurface liquids to Mars' surface;(3)in what abundance are carbonates formed by atmospheric processes;(4)what properties of martian meteorites could be used to constrain their source locations;(5)the origin(s) of organic macromolecules;(6)was/is Mars inhabited;(7)how can missions designed to uncover microbial activity in the subsurface eliminate potential false positives caused by microbial contaminants from Earth;(8)how can we ensure that humans and microbes form a stable and benign biosphere;(9)should humans relate to putative extraterrestrial life from a biocentric viewpoint (preservation of all biology), or anthropocentric viewpoint of expanding habitation of space? Studies of Mars' evolution can shed light on the habitability of extrasolar planets. In addition, Mars exploration can drive future policy developments and confirm (or put into question) the feasibility and/or extent of human habitability of space.
Hilbert-Schmidt Operators vs. Integrable Systems of Elliptic Calogero-Moser Type III. The Heun Case

description: The Heun equation can be rewritten as an eigenvalue equation for an ordinary differential operator of the form $-d^2/dx^2+V(g;x)$, where the potential is an elliptic function depending on a coupling vector $g\in{\mathbb R}^4$. Alternatively, this operator arises from the $BC_1$ specialization of the $BC_N$ elliptic nonrelativistic Calogero-Moser system (a.k.a. the Inozemtsev system). Under suitable restrictions on the elliptic periods and on $g$, we associate to this operator a self-adjoint operator $H(g)$ on the Hilbert space ${\mathcal H}=L^2([0,ω_1],dx)$, where $2ω_1$ is the real period of $V(g;x)$. For this association and a further analysis of $H(g)$, a certain Hilbert-Schmidt operator ${\mathcal I}(g)$ on ${\mathcal H}$ plays a critical role. In particular, using the intimate relation of $H(g)$ and ${\mathcal I}(g)$, we obtain a remarkable spectral invariance: In terms of a coupling vector $c\in{\mathbb R}^4$ that depends linearly on $g$, the spectrum of $H(g(c))$ is invariant under arbitrary permutations $σ(c)$, $σ\in S_4$.

description: CLIP (Contrastive Language-Image Pretraining) is an efficient method for learning computer vision tasks from natural language supervision that has powered a recent breakthrough in deep learning due to its zero-shot transfer capabilities. By training from image-text pairs available on the internet, the CLIP model transfers non-trivially to most tasks without the need for any data set specific training. In this work, we use CLIP to implement the engine of the popular game "Guess who?", so that the player interacts with the game using natural language prompts and CLIP automatically decides whether an image in the game board fulfills that prompt or not. We study the performance of this approach by benchmarking on different ways of prompting the questions to CLIP, and show the limitations of its zero-shot capabilites.

description: We study the response of the low-degree, solar p-mode frequencies to the unusually extended minimum of solar surface activity since 2007. A total of 4768 days of observations collected by the space-based, Sun-as-a-star helioseismic GOLF instrument are analyzed. A multi-step iterative maximum-likelihood fitting method is applied to subseries of 365 days and 91.25 days to extract the p-mode parameters. Temporal variations of the l=0, 1, and 2 p-mode frequencies are then obtained from April 1996 to May 2009. While the p-mode frequency shifts are closely correlated with solar surface activity proxies during the past solar cycles, the frequency shifts of the l=0 and l=2 modes show an increase from the second half of 2007, when no significant surface activity is observable. On the other hand, the l=1 modes follow the general decreasing trend of the solar surface activity. The different behaviours between the l=0 and l=2 modes and the l=1 modes can be interpreted as different geometrical responses to the spatial distribution of the solar magnetic field beneath the surface of the Sun. The analysis of the low-degree, solar p-mode frequency shifts indicates that the solar activity cycle 24 started late 2007, despite the absence of activity on the solar surface.

The AMXP XTE J1814-338 is known for having burst oscillations that are phase locked (constant phase difference) and coincident with the accretion powered pulsations during all its thermonuclear bursts but the last one. In this work we use a coherent timing analysis to investigate this phenomenon in more detail and with higher time resolution than was done in the past. We confirm that the burst oscillation phases are, on average, phase locked to the accretion powered pulsations. However, they also display moderate (

description: We present a detailed analysis of the dynamics of photon transport in waveguiding systems in the presence of a two-level system. In these systems, quantum interference effects generate a strong effective optical nonlinearity on the few-photon level. We clarify the relevant physical mechanisms through an appropriate quantum many-body approach. Based on this, we demonstrate that a single-particle photon-atom bound state with an energy outside the band can be excited via multi-particle scattering processes. We further show that these trapping effects are robust and, therefore, will be useful for the control of photon entanglement in solid-state based quantum optical systems.

description: We study the anisotropic pinning-mode resonances in the rf conductivity spectra of the stripe phase of 2D electron systems (2DES) around Landau level filling 9/2, in the presence of an in-plane magnetic field, B_ip. The polarization along which the resonance is observed switches as B_ip is applied, consistent with the reorientation of the stripes. The resonance frequency, a measure of the pinning interaction between the 2DES and disorder, increases with B_ip. The magnitude of this increase indicates that disorder interaction is playing an important role in determining the stripe orientation.

description: Filicaleyrodes spp. DISTRIBUTION & HOST PLANTS. Tanzania, on Pteridaceae: Pteris usambarensis; ex­Mauritius at Kew Gardens, UK, on Dryopteridaceae: Ctenitis sp.; Costa Rica, on Pteridaceae: Adiantum platyphyllum ­group. COMMENTS. Takahashi (1962) considered that Filicaleyrodes differed from Trialeurodes in possessing apically truncate papillae, “tracheal clefts” (indentations of the margin at the thoracic and caudal tracheal openings), a thickened margin to the vasiform orifice (which he described as a sclerotised ring surrounding the orifice), and transverse striations punctuating the caudal furrow. F. bosseri Takahashi, and F. williamsi (Trehan), are the only described members of this genus and yet F. williamsi does not possess the last two of the four generic distinguishing characters. Filicaleyrodes is clearly closely related to Trialeurodes and Dialeurolonga (the puparia of both genera with lingula lobulate and usually with submarginal papillae), with F. williamsi having originally been placed in Trialeurodes. The original characters used by Takahashi to distinguish Filicaleyrodes from Trialeurodes do not appear reliable, especially when the three undescribed species listed here are considered. In particular, one of these has papillae with bifid apices (Mauritius), one has no papillae (Tanzania) and one has acute papillae but only at the anterior and posterior ends of the puparium (Costa Rica); none of these three species, nor F. williamsi, has transverse striations punctuating the caudal furrow; the degree of modification of the puparial margin at the tracheal openings is very variable, as is the degree of thickening of the vasiform orifice margin. These undescribed species are represented almost entirely by poor specimens, but Filicaleyrodes evidently requires redefining when better material, and possibly additional taxa, are available for study. At present, these three species appear more referrable to Filicalyrodes than to Trialeurodes or Dialeurolonga.

A Distributed Trust Diffusion Protocol for Ad Hoc Networks
Creators: name: Morvan, Michel

Publisher: name: arXiv
Year: 2009
Subjects: subject: Networking and Internet Architecture (cs.NI)

description: In this paper, we propose and evaluate a distributed protocol to manage trust diffusion in ad hoc networks. In this protocol, each node i maintains a \trust value" about an other node j which is computed both as a result of the exchanges with node j itself and as a function of the opinion that other nodes have about j. These two aspects are respectively weighted by a trust index that measures the trust quality the node has in its own experiences and by a trust index representing the trust the node has in the opinions of the other nodes. Simulations have been realized to validate the robustness of this protocol against three kinds of attacks: simple coalitions, Trojan attacks and detonator attacks.

description: In a superfluid system, Off-Diagonal Long-Range Order (ODLRO) is expected to be exhibited in the appropriate reduced density matrices when the relevant particles (either bosons or fermion pairs) are considered to recede sufficiently far apart from each other. This concept is usually exploited to identify the value of the condensate density, without explicit concern, however, on the spatial range over which this asymptotic condition can effectively be achieved. Here, based on a diagrammatic approach that includes beyond-mean-field pairing fluctuations in the broken-symmetry phase at the level of the $t$-matrix also with the inclusion of the Gorkov-Melik-Barkhudarov (GMB) correction, we present a systematic study of the two-particle reduced density matrix for a superfluid fermionic system undergoing the BCS-BEC crossover, when the entities to recede far apart from each other evolve with continuity from largely overlapping Cooper pairs in the BCS limit to dilute composite bosons in the BEC limit. By this approach, we not only provide the coupling and temperature dependence of the condensate density at the level of our diagrammatic approach which includes the GMB correction, but we also obtain the evolution of the spatial dependence of the two-particle reduced density matrix, from a power-law at low temperature to an exponential dependence at high temperature in the superfluid phase, when the inter-particle coupling spans the BCS-BEC crossover. Our results put limitations on the minimum spatial extent of a finite-size system for which superfluid correlations can effectively be established.

Negotiating the decision : what is a police matter
Creators: name: Errington, Barbara Gene
Publisher: name: University of British Columbia
Year: 2011

description: Most sociological studies of the police tend to be concerned with aspects of their social control function in society. Few researchers have treated the day to day duties of the police as part of the performance of a work role. This study reports on the social activities performed by police and civilian personnel in a specific phase of police organization — the phone room. It is through these routines and practices that this aspect of police work is done. The study is based on observations made in the phone room of the Vancouver Police Station. Tape recordings were made of a number of calls. As an adjunct to observational data, interviews were held with members of the staff. Members of the community phone in to the police to report a variety of troubles. Staff, through their routine practices, select and work up from these calls, those which will be treated as "police business." "Police business" is thus viewed as produced by the routine practices of the phone room staff. This study examines some of these routine practices through which police business is accomplished. A section of this study deals with the kinds of callers staff consider are entitled to make a report because of their relationship to the event they are reporting; callers who stand in a special relationship to the police; and those features of the caller's account that police attend to in assigning the event described in the call to an administrative category. The police mandate to take action is discussed, and consideration is given to some of the organization factors that phone room staff take into account in exercising discretionary power to use that mandate. A final section deals with two typifications of people commonly made by phone room staff — "missing persons", and "crank callers." Phone room staff make these typifications based on their knowledge of the community and the exigencies of phone room work.

description: The main goal of autonomous driving is the complete removal of human supervision from the work-flow of autonomous vehicles. This objective represents an opportunity for enhancing quality of life by reducing traffic, removing parking spaces in cities, increasing collective fuel efficiency, and reducing accidents. As autonomous driving is progressively getting integrated into our daily lives, viable solutions are required for its challenges. Artificial intelligence is the main technology that provides intelligent agents with the capability to perceive visual information in a way similar or even superior to human agents. In recent years the deep learning methods showed their outstanding power in dealing with various data processing tasks. Most of the open problems in autonomous driving are focused on the surrounding environment, and some are within the cabin. This dissertation presents solutions to selected problems in both domains using deep learning methods with various sensor modalities. We introduce a model that is able to extract the geometric relationship between two camera images. These results then allow us to proceed with the development of a model to solve geometric transformation in a sequence of point-cloud observations to address the odometry problem. Our proposed method is directly consuming the point-clouds in real-time. Further, we develop the first publicly available comprehensive Radar dataset and propose an open space segmentation model for this task. Lastly, we present a method that uses thermal imaging within the vehicle to count the number of passengers. The thermal images are hiding most of the visual features of passengers and better respect their privacy.
Se mira, pero no se toca. Ojo colonizador y piel indígena en la ciencia ficción hispanoamericana contemporánea (Castagnet, Barragán, Paz Soldán)

description: En la ciencia ficción contemporánea se distinguen dos narraciones sobre lo humano: unas, subrepticiamente conservadoras, consolidan la “realidad capital”, otras son portadoras de una marginalidad inconforme. Propongo asociar con las primeras la idea de una ciencia ficción ‘ojo-céntrica’, que entroniza el ojo, con las segundas, una producción ‘somato-céntrica’, que reivindica el cuerpo como lugar de enunciación abyecto y ‘comprometido’: las poéticas de Castagnet, Barragán y Paz Soldán señalan esta tendencia continental latinoamericana a una ciencia ficción a la vez posthumana y postcolonial.

Arrested Kondo effect and hidden order in URu_2Si_2

description: Complex electronic matter exhibit subtle forms of self organization which are almost invisible to the available experimental tools, but which have dramatic physical consequences. One prominent example is provided by the actinide based heavy fermion material URu_2Si_2. At high temperature, the U-5f electrons in URu_2Si_2 carry a very large entropy. This entropy is released at 17.5K via a second order phase transition to a state which remains shrouded in mystery, and which was termed a "hidden order" state. Here we develop a first principles theoretical method to analyze the electronic spectrum of correlated materials as a function of the position inside the unit cell of the crystal, and use it to identify the low energy excitations of the URu_2Si_2. We identify the order parameter of the hidden order state, and show that it is intimately connected with magnetism. We present first principles results for the temperature evolution of the electronic states of the material. At temperature below 70K U-5f electrons undergo a multichannel Kondo effect, which is arrested at low temperature by the crystal field splitting. At lower temperatures, two broken symmetry states emerge, characterized by a complex order parameter ψ. A real $ψ$ describes the hidden order phase, and an imaginary ψcorresponds to the large moment antiferromagnetic phase, thus providing a unified picture of the two broken symmetry phases, which are realized in this material.

description: Este artigo estuda a produção e a circulação de um vídeo produzido pelo YouTuber Felipe Castanhari sobre a ditadura civil-militar brasileira. Argumenta-se que a narrativa elaborada pelo YouTuber atualiza certa interpretação histórica e memorial sobre a ditadura – a chamada “teoria dos dois demônios” – e que sua veiculação pelo YouTube satisfaz uma demanda por um passado customizado e personalizado, um passado on demand. Desta forma, contribuímos para as análises sobre as disputas de memória sobre a ditadura em ambientes virtuais, relacionando conteúdo e forma.

description: Using an effective Lagrangian approach we analyze a generic Higgsless model with composite heavy fermions, transforming as SU(2)_{L+R} Doublets. Assuming that the Standard Model fermions acquire mass through mixing with the new heavy fermions, we constrain the free parameters of the effective Lagrangian studying Flavour Changing Neutral Current processes. In so doing we obtain bounds that can be applied to a wide range of models characterized by the same fermion mixing hypothesis.

description: Approximate computing is an attractive paradigm for reducing the design complexity of error-resilient systems, therefore improving performance and saving power consumption. In this work, we propose a new two-level approximate logic synthesis method based on cube insertion and removal procedures. Experimental results have shown significant literal count and runtime reduction compared to the state-of-the-art approach. The method scalability is illustrated for a high error threshold over large benchmark circuits. The obtained solutions have presented a literal number reduction up to 38%, 56% and 93% with respect to an error rate of 1%, 3% and 5%, respectively.
