Can the early X-ray afterglow of GRBs be explained by a contribution from the reverse shock?

description: We propose to explain the recent observations of GRB early X-ray afterglows with SWIFT by the dissipation of energy in the reverse shock which crosses the ejecta as it is decelerated by the burst environment. We compute the evolution of the dissipated power and discuss the possibility that a fraction of it can be radiated in the X-ray range. We show that this reverse shock contribution behaves in a way very similar to the observed X-ray afterglows if the following two conditions are satisfied: (i) the Lorentz factor of the material which is ejected during the late stages of source activity decreases to small values Gamma < 10 and (ii) a large part of the shock dissipated energy is transferred to a small fraction (zeta < 0.1) of the electron population. We also discuss how our results may help to solve some puzzling problems raised by multiwavelength early afterglow observations such as the presence of chromatic breaks.

description: Analysis of cellular ATP in hybridoma and BHK-21 cell cultures was investigated as a method of determining viable biomass. Cell specific ATP content in hybridoma and BHK batch cultures varied from 8 to 2 fmol/viable cell. ATP levels and cell volumes were highest during exponential growth and decreased during the stationary and decline phases. Cell specific ATP correlated directly with the viable cell volume rather than the viable cell numbers. In hybridoma cultures with between 90 and 35% viable cells, the average intracellular ATP concentration of viable cells was 4.2 mM with less than 10% variation. Intracellular ATP decreased rapidly after cell death due to freeze-thaw. Within 20 min, the sample ATP concentration decreased by two orders of magnitude to approach background levels. There were no significant changes in the concentration of intracellular ATP during 1000 h of hybridoma continuous culture. During this time, hybridoma cells were exposed to pHs ranging from 6.8 to 8.0 and dissolved oxygen concentrations ranging from 3 to 80% of air saturation. Analysis of cellular ATP concentration provided a more accurate estimate of viable biomass than LDH analysis or microscopic cell counts over the course of a 500 h high density perfusion culture of CHO cells.

description: In its first encounter at solar distances as close as r = 0.16AU, Parker Solar Probe (PSP) observed numerous local reversals, or inversions, in the heliospheric magnetic field (HMF), which were accompanied by large spikes in solar wind speed. Both solar and in situ mechanisms have been suggested to explain the existence of HMF inversions in general. Previous work using Helios 1, covering 0.3-1AU, observed inverted HMF to become more common with increasing r, suggesting that some heliospheric driving process creates or amplifies inversions. This study expands upon these findings, by analysing inversion-associated changes in plasma properties for the same large data set, facilitated by observations of 'strahl' electrons to identify the unperturbed magnetic polarity. We find that many inversions exhibit anti-correlated field and velocity perturbations, and are thus characteristically Alfvénic, but many also depart strongly from this relationship over an apparent continuum of properties. Inversions depart further from the 'ideal' Alfvénic case with increasing r, as more energy is partitioned in the field, rather than the plasma, component of the perturbation. This departure is greatest for inversions with larger density and magnetic field strength changes, and characteristic slow solar wind properties. We find no evidence that inversions which stray further from 'ideal' Alfvénicity have different generation processes from those which are more Alfvénic. Instead, different inversion properties could be imprinted based on transport or formation within different solar wind streams.

description: The analysis of complex physical systems hinges on the ability to extract the relevant degrees of freedom from among the many others. Though much hope is placed in machine learning, it also brings challenges, chief of which is interpretability. It is often unclear what relation, if any, the architecture- and training-dependent learned "relevant" features bear to standard objects of physical theory. Here we report on theoretical results which may help to systematically address this issue: we establish equivalence between the information-theoretic notion of relevance defined in the Information Bottleneck (IB) formalism of compression theory, and the field-theoretic relevance of the Renormalization Group. We show analytically that for statistical physical systems described by a field theory the "relevant" degrees of freedom found using IB compression indeed correspond to operators with the lowest scaling dimensions. We confirm our field theoretic predictions numerically. We study dependence of the IB solutions on the physical symmetries of the data. Our findings provide a dictionary connecting two distinct theoretical toolboxes, and an example of constructively incorporating physical interpretability in applications of deep learning in physics.
Utility of antiproton-nucleus scattering for probing nuclear surface density distributions

description: Antiproton-nucleon ($\bar{p}N$) total cross sections are typically 3-4 times larger than the $NN$ ones at incident energies from a few hundreds to thousands MeV. We investigate antiproton-nucleus scattering as it could work as a probe of the nuclear structure giving the sensitivity differently from a proton probe. High-energy antiproton-nucleus reactions are reasonably described by the Glauber model with a minimal profile function that reproduces the $\bar{p}N$ and $\bar{p}$-$^{12}$C cross section data. In contrast to the proton-nucleus scattering, we find that the complete absorption occurs even beyond the nuclear radius due to the large $\bar{p}N$ elementary cross sections, which shows stronger sensitivity to the nuclear density distribution in the tail region. This sensitivity is quantified in the total reaction cross sections with various density profiles for future measurement including neutron-rich unstable nuclei.

Using a sample of 383.2 +/- 4.2 million BBbar pairs collected by the BaBar detector, we measure CP-averaged branching fractions and direct CP asymmetries for intermediate resonant and nonresonant contributions. We find evidence for direct CP violation in the decay B+ -> rho0(770) K+, with a CP violation parameter A_CP = (+44 +/- 10 +/- 4 +5,-13)%.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: Perturbative corrections to the mean field theory for particle-hole instabilities of interacting electron systems are computed within a scheme which is equivalent to the recently developed variational approach to the Kohn-Luttinger superconductivity. This enables an unbiased comparison of particle-particle and particle-hole instabilities within the same approximation scheme. A spin-rotation invariant formulation for the particle-hole instabilities in the triplet channel is developed. The method is applied to the phase diagram of the t-t' Hubbard model on the square lattice. At the Van Hove density, antiferromagnetic and d-wave Pomeranchuk phases are found to be stable close to half filling. However, the latter phase is confined to an extremely narrow interval of densities and away from the singular filling, d-wave superconducting instability dominates.

description: Hopfield neural networks are a possible basis for modelling associative memory in living organisms. After summarising previous studies in the field, we take a new look at learning rules, exhibiting them as descent-type algorithms for various cost functions. We also propose several new cost functions suitable for learning. We discuss the role of biases (the external inputs) in the learning process in Hopfield networks. Furthermore, we apply Newtons method for learning memories, and experimentally compare the performances of various learning rules. Finally, to add to the debate whether allowing connections of a neuron to itself enhances memory capacity, we numerically investigate the effects of self coupling.

description: Pelvic fractures, often caused by high-impact trauma, frequently require surgical intervention. Imaging techniques such as CT and 2D X-ray imaging are used to transfer the surgical plan to the operating room through image registration, enabling quick intraoperative adjustments. Specifically, segmenting pelvic fractures from 2D X-ray imaging can assist in accurately positioning bone fragments and guiding the placement of screws or metal plates. In this study, we propose a novel deep learning-based category and fragment segmentation (CFS) framework for the automatic segmentation of pelvic bone fragments in 2D X-ray images. The framework consists of three consecutive steps: category segmentation, fragment segmentation, and post-processing. Our best model achieves an IoU of 0.91 for anatomical structures and 0.78 for fracture segmentation. Results demonstrate that the CFS framework is effective and accurate.

description: (Abridged) Exploiting the sensitivity and broad band width of NOEMA, we have studied the molecular gas and dust in the galaxy HerBS-89a, at z=2.95. High angular resolution images reveal a partial 1.0" diameter Einstein ring in the dust continuum emission and the molecular emission lines of 12CO(9-8) and H2O(2_02-1_11). We report the detection of the three fundamental transitions of the molecular ion OH+, seen in absorption; the molecular ion CH+(1-0) seen in absorption (and tentatively in emission); two transitions of amidogen (NH2), seen in emission; and HCN(11-10) and/or NH(1_2-0_1) seen in absorption. The NOEMA data are complemented with VLA data tracing the 12CO(1-0) emission line, which provides a measurement of the total mass of molecular gas and an anchor for a CO excitation analysis. In addition, we present HST imaging that reveals the foreground lensing galaxy in the near-infrared. Together with data from the GTC, we derive a photometric redshift of z(phot)~0.9 for the foreground lensing galaxy. Modelling the lensing of HerBS-89a, we reconstruct the dust continuum and molecular emission lines (magnified by a factor ~4-5) in the source plane. The 12CO(9-8) and H2O emission lines have comparable spatial and kinematic distributions; the source-plane reconstructions do not clearly distinguish between a one-component and a two-component scenario, but the latter accounts for the observed broad line widths. HerBS-89a is a powerful star forming galaxy with a dust-to-gas ratio delta(GDR)~80, a SFR = 614 +/- 59 Msun/yr and a depletion timescale tau(depl) = (3.4 +/- 1.0) 1e8 years. The OH+ and CH+ absorption lines, all have their main velocity component red-shifted by Δ(V)~100 km/s relative to the global CO reservoir. We argue that these absorption lines trace a rare example of gas inflow towards the center of the galaxy.

 Echinometra subangularis Desmoulins—Agassiz 1872: 234.
 See: Mortensen (1943a: 357–368, figs. 172–175, pl. 41, figs. 1–5, pl. 42, figs. 12–14, pl. 43, figs. 1–13, pl. 44, fig. 9, pl. 64, figs. 17, 20–24); Pawson (1978: 20–23, figs. 8–10).
 Occurrence: Atlantic, from North Carolina and Bermuda, southwards to Brazil (Mortensen 1943a, Schultz 2006), and eastwards from Cape Verde to Angola (H.L. Clark 1925, Mortensen 1936); the subspecies E. lucunter polypora is restricted to Ascension and St. Helena islands (Pawson 1978).
 Depth: 0–45 m (Mortensen 1943a).
 Habitat: hard substrates (bioeroder; Mortensen 1943a).
 Larval stage: planktotrophic (Mortensen 1921).
 Fossil record: Ericichnus bromleyi, a relatively recent described ichnospecies portraying groove-borings found in a Pliocene fossiliferous outcrop in Malbusca (Santa Maria Island) is thought to be made by the sea urchin Echinometra lucunter (see Santos et al. 2015).
 Commercial value: edible (Lawrence 2007).
 Remarks: Agassiz (1872) listed the Azores under the geographical range of Echinometra lucunter (under the name Echinometra subangularis), which is clearly a misprint. The author never mentioned the archipelago again, whether listing the examined specimens’ locations or discussing the distribution range for this species. This tropical species does not occur in the present-day shallow waters of the Azores and no specimens were ever reported from the area.

description: We experimentally study quantum Zeno effects in a parity-time (PT) symmetric cold atom gas periodically coupled to a reservoir. Based on the state-of-the-art control of inter-site couplings of atoms in a momentum lattice, we implement a synthetic two-level system with passive PT symmetry over two lattice sites, where an effective dissipation is introduced through repeated couplings to the rest of the lattice. Quantum Zeno (anti-Zeno) effects manifest in our experiment as the overall dissipation of the two-level system becoming suppressed (enhanced) with increasing coupling intensity or frequency. We demonstrate that quantum Zeno regimes exist in the broken PT symmetry phase, and are bounded by exceptional points separating the PT symmetric and PT broken phases, as well as by a discrete set of critical coupling frequencies. Our experiment establishes the connection between PT-symmetry-breaking transitions and quantum Zeno effects, and is extendable to higher dimensions or to interacting regimes, thanks to the flexible control with atoms in a momentum lattice.

description: The design and application of an instrumented particle for the lagrangian characterization of turbulent free surface flows is presented in this study. This instrumented particle constitutes a local measurement device capable of measuring both its instantaneous 3D translational acceleration and angular velocity components, as well as recording them on an embarked removeable memory card. A lithium ion polymer battery provides the instrumented particle with up to 8 hours of autonomous operation. Entirely composed of commercial off the shelf electronic components, it features accelerometer and gyroscope sensors with a resolution of 16 bits for each individual axis, and maximum data acquisition rates of 1 and 8 kHz, respectively, as well as several user programmable dynamic ranges. Its ABS 3D printed body takes the form of a 36 mm diameter hollow sphere, and has a total mass of (19.6 $\pm$ 0.5) g. Controlled experiments, carried out to calibrate and validate its performance showed good agreement when compared to reference techniques. In order to assess the practicality of the instrumented particle, we apply it to the statistical characterization of floater dynamics in experiments of surface wave turbulence. In this feasibility study, we focused our attention on the distribution of acceleration and angular velocity fluctuations as a function of the forcing intensity. The IP's motion is also simultaneously registered by a 3D particle tracking velocimetry (PTV) system, for the purposes of comparison. Beyond the results particular to this study case, it constitutes a proof of both the feasibility and potentiality of the IP as a tool for the experimental characterization of particle dynamics in such flows.

description: This paper discusses the use of data mining techniques in the financial statements for classification and prediction of listed companies. The test sample contains 80 companies listed on the Athens Stock Exchange for the fiscal year 2013, which includes 40 companies traded on the main market and the remaining 40 companies are in the category of supervision. Specifically, five data mining techniques are applied such as, J48 Decision Tree, Naive Bayes, Polynomial Logistic Regression, Support Vector Machines (SVM) and Binomial Logistic Regression. The algorithms are compared based on the accuracy of the correct classification of the total sample. Furthermore, financial ratios that give the best information for accurate classification are presented. The survey results show that they can be used as an additional tool to auditors and to others.
A proof of the strong cosmic censorship conjecture

description: The Penrose strong cosmic censorship conjecture asserts that Cauchy horizons inside dynamically formed black holes are unstable to remnant matter fields that fall into the black holes. The physical importance of this conjecture stems from the fact that it provides a necessary condition for general relativity to be a truly deterministic theory of gravity. Determining the fate of the Penrose conjecture in non-asymptotically flat black-hole spacetimes has been the focus of intense research efforts in recent years. In the present essay we provide a remarkably compact proof, which is based on Bekenstein's generalized second law of thermodynamics, for the validity of the intriguing Penrose conjecture in physically realistic (dynamically formed) curved black-hole spacetimes.

Natives and reserve establishment in nineteenth century British Columbia
Creators: name: Seymour, Anne Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: Conventional academic argument has it that reserve establishment in British Columbia was something which was imposed upon a subjugated, oppressed population. This argument suggests that after eighty years of mutually beneficial socio-economic interaction with Europeans, Natives were suddenly unable to cope with the effects of European settlement. Careful scrutiny of relevant documents from reserve commissions, however, tends to suggest a different interpretation. Although faced with the societal effects of depopulation as a result of epidemic disease, and in spite of restrictions placed upon them by European law and Victorian hegemonic beliefs, Natives were able to maintain their cultural integrity and participate effectively within European systems of power. Although the agenda and objectives of Natives with regard to land were not evident to contemporary Europeans, they are beginning to be seen and understood by historians and other observers.

description: The number of solutions in finite fields of a system of polynomial equations obeys a very strong regularity, reflected for example by the rationality of the zeta function of an algebraic variety defined over a finite field, or the modularity of Hasse-Weil's $L$-function of an elliptic curve over $\Q$. Since two decades, efficient methods have been invented to compute effectively this number of solutions, notably in view of cryptographic applications. This exposé presents some of these methods, generally relying on the use of Lefshetz's trace formula in an adequate cohomology theory and discusses their respective advantages. ----- Le nombre de solutions dans les corps finis d'un système d'équations polynomiales obéit à une très forte régularité, reflétée par exemple par la rationalité de la fonction zêta d'une variété algébrique sur un corps fini, ou la modularité de la fonction $L$ de Hasse-Weil d'une courbe elliptique sur $\Q$. Depuis une vingtaine d'années des méthodes efficaces ont été inventées pour calculer effectivement ce nombre de solutions, notamment en vue d'applications à la cryptographie. L'exposé en présentera quelques-unes, généralement fondées l'utilisation de la formule des traces de Lefschetz dans une théorie cohomologique convenable, et expliquera leurs avantages respectifs.

Homolampas fragilis

description: Erroneous— Homolampas fragilis (Agassiz, 1869)   Reports for the Azores:
 non Homolampas fragilis (Agassiz) —A.H. Clark 1949: 376, 377. [misidentified A. atlantica]
 Type locality: Caribbean.
 See: Mortensen (1950: 266–272, pl. 7, figs. 5–6, pl. 13, figs. 5, pl. 25, figs. 1,4, 13, 15–18); Benavides-Serrato et al. (2012: 118).
 Occurrence: Western Atlantic, known only from the Gulf of Mexico and the Caribbean (Mortensen 1950).
 Depth: 550– 3,550 m (Mortensen 1950).
 Habitat: infaunal, in soft bottoms (Pawson et al. 2009).
 Remarks: A.H. Clark (1949) reported this species from the Azores, based fragments of two medium-sized specimens retrieved by Atlantis, west of S„o Miguel Island (cruise 152, sta 20: 37°50’30”N, 26°00’00”W, 2,562 m). Later, Serafy (1974) re-examined one of the specimens and assigned it to his newly described species, Araeolampas atlantica. The second specimen of H.L. Clark was not mentioned by Serafy, but it seems likely that this also was an Araeolampas, since H. fragilis does not reach a size larger than 35 mm (Serafy 1974) and confirmed records of H. fragilis are restricted to the West Atlantic.

description: The most precise determination of Vus comes from semileptonic kaon decays. We have measured with the KLOE detector at DAFNE, the Frascati phi-factory, all the experimental inputs to Vus for both neutral and charged kaons. Using our results we extract the value of Vus with ~0.9% fractional error, which is dominated by the theoretical error on the form factor, f+(0). A new determination of the ratio Vus/Vud is also presented, based on our precise measurement of the absolute branching ratio for the decay K -> mu nu (gamma), combined with lattice results for the ratio f_K/f_pi. New results on CPT symmetry and quantum mechanics test have also been achieved, which are based on the first measurement of the charged asymmetry for KS -> pi e nu decay and on interferometry studies using the phi -> KL KS -> pi+ pi- pi+ pi-.

A Simple Proof of the Entropy-Power Inequality via Properties of Mutual Information
Creators: name: Rioul, Olivier
Publisher: name: arXiv
Year: 2007
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: While most useful information theoretic inequalities can be deduced from the basic properties of entropy or mutual information, Shannon's entropy power inequality (EPI) seems to be an exception: available information theoretic proofs of the EPI hinge on integral representations of differential entropy using either Fisher's information (FI) or minimum mean-square error (MMSE). In this paper, we first present a unified view of proofs via FI and MMSE, showing that they are essentially dual versions of the same proof, and then fill the gap by providing a new, simple proof of the EPI, which is solely based on the properties of mutual information and sidesteps both FI or MMSE representations.

Rotation symmetry of the multiple-relaxation-time collision model

description: In the Hermite-expansion-based multiple-relaxation-time lattice Boltzmann (LB) model [Shan & Chen, Int. J. Mod. Phys. C, 18, 635, (2007)], a separate relaxation time is assigned to each of the tensorial moments of the collision term. Here we point out that to allow maximum flexibility while preserving the rotational symmetry of the relaxation physics, separate relaxation times can be assigned to the components of a tensor corresponding to its irreducible representation of SO(3) but not any finer. By decomposing the second moment in the LB model for polyatomic gases [Nie, Shan & Chen, Phys. Rev. E 77, 035701, (2008)], a model with decoupled shear and bulk viscosity is constructed. Hydrodynamic equation of the model is obtained via Chapman-Enskog calculation and verified by numerical simulation.
Self-consistent theory of mobility edges in quasiperiodic chains

description: We introduce a self-consistent theory of mobility edges in nearest-neighbour tight-binding chains with quasiperiodic potentials. Demarcating boundaries between localised and extended states in the space of system parameters and energy, mobility edges are generic in quasiperiodic systems which lack the energy-independent self-duality of the commonly studied Aubry-André-Harper model. The potentials in such systems are strongly and infinite-range correlated, reflecting their deterministic nature and rendering the problem distinct from that of disordered systems. Importantly, the underlying theoretical framework introduced is model-independent, thus allowing analytical extraction of mobility edge trajectories for arbitrary quasiperiodic systems. We exemplify the theory using two families of models, and show the results to be in very good agreement with the exactly known mobility edges as well numerical results obtained from exact diagonalisation.

Multiscale dimension reduction for flow and transport problems in thin domain with reactive boundaries

description: In this paper, we consider flow and transport problems in thin domains. The mathematical model considered in the paper is described by a system of equations for velocity, pressure, and concentration, where the flow is described by the Stokes equations and the transport is described by an unsteady convection-diffusion equation with non-homogeneous boundary conditions on walls (reactive boundaries). We start with the finite element approximation of the problem on unstructured grids and use it as a reference solution for two and three-dimensional model problems. Fine grid approximation resolves complex geometries on the grid level and leads to a large discrete system of equations that is computationally expensive to solve. To reduce the size of the discrete systems, we develop a multiscale model reduction technique, where we construct local multiscale basis functions to generate a lower-dimensional model on a coarse grid. The proposed multiscale model reduction is based on the Discontinuous Galerkin Generalized Multiscale Finite Element Method (DG-GMsGEM). In DG-GMsFEM for flow problems, we start with constructing the snapshot space for each interface between coarse grid cells to capture possible flows. For the reduction of the snapshot space size, we perform a dimension reduction via a solution of the local spectral problem and use eigenvectors corresponding to the smallest eigenvalues as multiscale basis functions for the approximation on the coarse grid. For the transport problem, we construct multiscale basis functions for each interface between coarse grid cells and present additional basis functions to capture non-homogeneous boundary conditions on walls. Finally, we will present some numerical simulations for three test geometries for two and three-dimensional problems to demonstrate the method's performance.

description: This paper presents a static generation expansion planning formulation in which operational and investment decisions for a wide range of technologies are co-optimized from a centralized perspective. The location, type and quantity of new generation and storage capacities are provided such that system demand and flexibility requirements are satisfied. Depending on investments in new intermittent renewables (wind, PV), the flexibility requirements are adapted in order to fully capture RES integration costs and ensure normal system operating conditions. To position candidate units, we incorporate DC constraints, nodal demand and production of existing generators as well as imports and exports from other interconnected zones. To show the capabilities of the formulation, high-temporal resolution simulations are conducted on a 162-bus system consisting of the full Swiss transmission grid and aggregated neighboring countries.
