description: Previous work has shown that the standard supergravity approximation can break down when using AdS/CFT duality to study certain top-down formulations of the jet stopping problem in strongly-coupled N=4 super-Yang-Mills (SYM) plasmas, depending on the virtuality of the source of the "jet." In this paper, we identify the nature of this breakdown: High-momentum gravitons in the gravitational dual get stretched into relatively large classical string loops by tidal forces associated with the black brane. These stringy excitations of the graviton are not contained in the supergravity approximation, but we show that the jet stopping problem can nonetheless still be solved by drawing on various string-theory methods (the eikonal approximation, the Penrose limit, string quantization in pp-wave backgrounds) to obtain a probability distribution for the late-time classical string loops. In extreme cases, we find that the gravitons are stretched into very long folded strings which are qualitatively similar to the folded classical strings originally used by Gubser, Gulotta, Pufu and Rocha to model the jet stopping problem. This makes a connection in certain cases between the different methods that have been used to study jet stopping with AdS/CFT and gives a specific example of a precise N=4 SYM problem that generates such strings in the gravity description.

A new variable in scalar cosmology with exponential potential

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We present a new way describing the solution of the Einstein-scalar field theory with exponential potential $V\propto e^{\sqrt{6}βϕ/M_{Pl}}$ in spatially flat Friedmann-Robertson-Walker space-time. We introduced a new time variable, $L$, which may vary in $[-1,1]$. The new time represents the state of the universe clearly because the equation of state at a given time takes the simple form, $w= -1+ 2L^2$. The universe will inflate when $|L|<1/\sqrt{3}$. For $β\leq 1$, the universe ends with its evolution at $L=β$. This implies that the equation of state at the end of the universe is nothing but $w=-1+2β^2$. For $β\geq 1$, the universe ends at L=1, where the equation of state of the universe is one. On the other hand, the universe always begins with $w=1$ at $L=\pm 1$.

description: In the 1990s, Kempf and his collaborators Mangano and Mann introduced a $D$-dimensional $(β,β')$-two-parameter deformed Heisenberg algebra which leads to an isotropic minimal length $(\triangle X^{i})_{min}=\hbar\sqrt{Dβ+β'}\;,\forall i\in \{1,2, \cdots,D\}$. In this work, the Lagrangian formulation of a magnetostatic field in three spatial dimensions $(D=3)$ described by Kempf algebra is presented in the special case of $β'=2β$ up to the first order over $β$. We show that at the classical level there is a similarity between magnetostatics in the presence of a minimal length scale (modified magnetostatics) and the magnetostatic sector of the Abelian Lee-Wick model in three spatial dimensions. The integral form of Ampere's law and the energy density of a magnetostatic field in the modified magnetostatics are obtained. Also, the Biot-Savart law in the modified magnetostatics is found. By studying the effect of minimal length corrections to the gyromagnetic moment of the muon, we conclude that the upper bound on the isotropic minimal length scale in three spatial dimensions is $4.42\times10^{-19}m$. The relationship between magnetostatics with a minimal length and the Gaete-Spallucci non-local magnetostatics (J. Phys. A: Math. Theor. \textbf{45}, 065401 (2012)) is investigated.

description: Recently, two measures of electroweak finetuning (EWFT) have been introduced for SUSY models: Δ_{EW} compares the Z mass to each separate weak scale contribution to m_Z while Δ_{HS} compares the Z mass to high scale input parameters and their consequent renormalizaton group evolution (1/Δis the % of fine tuning). While the paradigm mSUGRA/CMSSM model has been shown to be highly finetuned under both parameters (Δ_{EW}> 10^2 and Δ_{HS}> 10^3), the two-parameter non-universal Higgs model (NUHM2) in the context of radiatively-driven natural SUSY (RNS) enjoys Δ_{EW} as low as 10, while Δ_{HS} remains > 10^3. We investigate finetuning in the 19-free-parameter SUGRA model (SUGRA19). We find that with 19 free parameters, the lowest Δ_{EW} points are comparable to what can be achieved in NUHM2 with just 6 free parameters. However, in SUGRA19, Δ_{HS} can now also reach as low as 5-10. The conditions which lead to low Δ_{HS} include m_{H_u} m_Z at the high scale, with non-universal gaugino masses M_{1,2}>> M_3 also at m_{GUT}. The low Δ_{HS} models are severely constrained by b\to sγbranching fraction. In both cases of low Δ_{EW} and Δ_{HS}, the superpotential μparameter should be \sim 100-300 GeV. While SUSY models with low EWFT may or may not be discoverable at LHC, the predicted light higgsinos must show up at a linear e^+e^- collider with \sqrt{s}> 2|μ|.

description: Normalized compression distance (NCD) is a parameter-free, feature-free, alignment-free, similarity measure between a pair of finite objects based on compression. However, it is not sufficient for all applications. We propose an NCD of finite multisets (a.k.a. multiples) of finite objects that is also a metric. Previously, attempts to obtain such an NCD failed. We cover the entire trajectory from theoretical underpinning to feasible practice. The new NCD for multisets is applied to retinal progenitor cell classification questions and to related synthetically generated data that were earlier treated with the pairwise NCD. With the new method we achieved significantly better results. Similarly for questions about axonal organelle transport. We also applied the new NCD to handwritten digit recognition and improved classification accuracy significantly over that of pairwise NCD by incorporating both the pairwise and NCD for multisets. In the analysis we use the incomputable Kolmogorov complexity that for practical purposes is approximated from above by the length of the compressed version of the file involved, using a real-world compression program. Index Terms--- Normalized compression distance, multisets or multiples, pattern recognition, data mining, similarity, classification, Kolmogorov complexity, retinal progenitor cells, synthetic data, organelle transport, handwritten character recognition

description: Layered metal dichalcogenide materials are a family of semiconductors with a wide range of energy band gaps and properties, and potential to open up new areas of physics and technology applications. However, obtaining high crystal quality thin films over a large area remains a challenge. Here we show that chemical vapor deposition (CVD) can be used to achieve large area electronic grade single crystal Molybdenum Disulfide (MoS2) thin films with the highest mobility reported in CVD grown films so far. Growth temperature and choice of substrate were found to critically impact the quality of film grown, and high temperature growth on (0001) orientated sapphire yielded highly oriented single crystal MoS2 films for the first time. Films grown under optimal conditions were found to be of high structural quality from high-resolution X-ray diffraction, transmission electron microscopy, and Raman measurements, approaching the quality of reference geological MoS2. Photoluminescence and electrical measurements confirmed the growth of optically active MoS2 with a low background carrier concentration, and high mobility. The CVD method reported here for the growth of high quality MoS2 thin films paves the way towards growth of a variety of layered 2D chalcogenide semiconductors and their heterostructures.

description: The spectrum and event rate of supernova relic neutrinos are calculated taking into account the dependence on the time it takes for the shock wave in supernova cores to revive. The shock revival time should depend on the still unknown explosion mechanism of collapse-driven supernovae. The contribution of black-hole-forming failed supernovae is also considered. The total event rate is higher for models with a longer shock revival time and/or a failed-supernova contribution. The hardness of the spectrum does not strongly depend on the shock revival time, but the spectrum becomes hard owing to the failed supernovae. Therefore, the shock-revival-time dependence of supernova relic neutrinos has different systematics from the fractions of failed supernovae.

description: We introduce a novel many body method which combines two powerful many body techniques, viz., quantum Monte Carlo and coupled cluster theory. Coupled cluster wave functions are introduced as importance functions in a Monte Carlo method designed for the configuration interaction framework to provide rigorous upper bounds to the ground state energy. We benchmark our method on the homogeneous electron gas in momentum space. The importance function used is the coupled cluster doubles wave function. We show that the computational resources required in our method scale polynomially with system size. Our energy upper bounds are in very good agreement with previous calculations of similar accuracy, and they can be systematically improved by including higher order excitations in the coupled cluster wave function.

description: Emergency shelters, which reflect the city's ability to respond to and deal with major public emergencies to a certain extent, are essential to a modern urban emergency management system. This paper is based on spatial analysis methods, using Analytic Hierarchy Process to analyze the suitability of the 28 emergency shelters in Wuhan City. The Technique for Order Preference by Similarity to an Ideal Solution is further used to evaluate the accommodation capacity of emergency shelters in central urban areas, which provides a reference for the optimization of existing shelters and the site selection of new shelters, and provides a basis for improving the service capacity of shelters. The results show that the overall situation of emergency shelters in Wuhan is good, with 96\% of the places reaching the medium level or above, but the suitability level needs to be further improved, especially the effectiveness and accessibility. Among the seven central urban areas in Wuhan, Hongshan District has the strongest accommodation capacity while Jianghan District has the weakest, with noticeable differences.

description: Hydrogen is one of the few molecules which has been incarcerated in the molecular cage of C$_{60}$ and forms endohedral supramolecular complex H$_2$@C$_{60}$. In this confinement hydrogen acquires new properties. Its translational motion becomes quantized and is correlated with its rotations. We applied infrared spectroscopy to study the dynamics of hydrogen isotopologs H$_2$, D$_2$ and HD incarcerated in C$_{60}$. The translational and rotational modes appear as side bands to the hydrogen vibrational mode in the mid infrared part of the absorption spectrum. Because of the large mass difference of hydrogen and C$_{60}$ and the high symmetry of C$_{60}$ the problem is identical to a problem of a vibrating rotor moving in a three-dimensional spherical potential. The translational motion within the C$_{60}$ cavity breaks the inversion symmetry and induces optical activity of H$_2$. We derive potential, rotational, vibrational and dipole moment parameters from the analysis of the infrared absorption spectra. Our results were used to derive the parameters of a pairwise additive five-dimensional potential energy surface for H$_2$@C$_{60}$. The same parameters were used to predict H$_2$ energies inside C$_{70}$[Xu et al., J. Chem. Phys., {\bf 130}, 224306 (2009)]. We compare the predicted energies and the low temperature infrared absorption spectra of H$_2$@C$_{70}$.

description: We have analyzed the problem of preserving and supporting breastfeeding. Based on a review of literature, the article deals with the issue of benefits of breastfeeding for both the child and the mother, reveals the concept of “lactation dominant”. The problems of the lactation period, including the possible manifestations of lactational crises, are discussed. At the same time, special attention is paid to hypogalactia, its causes, manifestations, prevention and treatment. Various methods of preserving, supporting and restoring lactation in women are described, including such a method of restarting breastfeeding, as relactation. We have assessed the possibilities of using the relactation even after cessation of lactation and the transition to a formula. Key words: breastfeeding, lactation dominant, lactational crisis, hypogalactia, relactation.

description: When using constellation synergy to image large areas for reconnaissance, it is required to achieve the coverage capability requirements with minimal consumption of observation resources to obtain the most optimal constellation observation scheme. With the minimum number of satellites and meeting the real-time ground coverage requirements as the optimization objectives, this paper proposes an optimized design of satellite constellation configuration for full coverage of large-scale regional imaging by using an improved simulated annealing algorithm combined with the real-time coverage evaluation method of hexagonal discretization. The algorithm can adapt to experimental conditions, has good efficiency, and can meet industrial accuracy requirements. The effectiveness and adaptability of the algorithm are tested in simulation applications.

description: We discuss model building in tribrid inflation, which is a framework for realising inflation in the matter sector of supersymmetric particle physics models. The inflaton is a D-flat combination of matter fields, and inflation ends by a phase transition in which some Higgs field obtains a vacuum expectation value. We first describe the general procedure for implementing tribrid inflation in realistic models of particle physics that can be applied to a wide variety of BSM particle physics models around the GUT scale. We then demonstrate how the procedure works for an explicit lepton flavour model based on an A_4 family symmetry. The model is both predictive and phenomenologically viable, and illustrates how tribrid inflation connects cosmological and particle physics parameters. In particular, it predicts a relation between the neutrino Yukawa coupling and the running of the spectral index alpha_s. We also show how topological defects from the flavour symmetry breaking can be avoided automatically.

In the conformal case this gives rise to a new solution that contains an AdS_5 X S^2 piece. In the case of non-conformal geometries we obtain a new background in massive IIA supergravity that presents similar behaviour to the cascade of Seiberg dualities. Some physical observables are discussed.

description: A stochastic metric can appear in classical as well as in quantum gravity. We show that if the linearized stochastic Gaussian gravitational plane wave has the frequency spectrum $ω^{4γ-1}$ ($0\leq γ<1$) then the equal-time propagator of the scalar field behaves as $p^{-\frac{1}{1-γ}}$for large momenta. We discuss models of quantum field theory where such anomalous behaviour can appear.

description: In our study we tested blood serum and adrenal gland tissue cortisol levels and investigated the possibility of correction of changes found with Garcinia Cambogia extract. In the experiment we used white male rats distributed into three age groups – immature, adult, and old. Alimentary obesity was modeled by means of dietary refined palm oil in dosage of 30 g per kg of body weight for six weeks. Intragastric administration of Garcinia extract (in dosage of 0.25 g per kg of body weight a day) was started after six weeks of palm oil intake had passed. Palm oil excess resulted in cortisol levels increase both in blood serum and adrenal gland tissue. Elevation of cortisol level progressed with the duration of the experiment. Use of Garcinia Cambogia extract in the dosage of 0.25 g per kg a day lead to a decrease of cortisol levels both in serum and adrenal gland tissue in experimental obese animals. Key words: Garcinia Cambogia extract, alimentary obesity, cortisol, palm oil.

description: In this work, we study the conditions under which fluorescent beads can be used to emulate single fluorescent molecules in the calibration of optical microscopes. Although beads are widely used due to their brightness and easy manipulation, there can be notable differences between the point spread functions (PSFs) they produce and those for single-molecule fluorophores, caused by their different emission pattern and their size. We study theoretically these differences for various scenarios, e.g. with or without polarization channel splitting, to determine the conditions under which the use of beads as a model for single molecules is valid. We also propose methods to model the blurring due to the size difference and compensate for it to produce PSFs that are more similar to those for single molecules.

description: En préambule au compte-rendu de cette excursion du Cercle vaudois de botanique sur l’adret au-dessus de Rossinière, on peut mentionner qu’elle se déroule en plein coeur du Parc naturel Gruyère Pays-d’Enhaut. Celui-ci est porteur de projet pour le réseau écologique (avec le bureau Drosera). Ensemble ils établissent des contrats avec les exploitants qui souhaitent inscrire des parcelles dans le périmètre du réseau écologique. Lors de ces inscriptions, des mesures en faveur de la biodiversité doivent être prises comme, par exemple, retarder la fauche à une certaine date ou laisser 10% non fauché lors de chaque utilisation d’une prairie. D’autre part des exploitants signent parfois des conventions avec le canton lorsque leur domaine se situe dans une zone de PPS (prairies et pâturages secs d’importance nationale), assez étendue dans cette région. Là aussi une fauche tardive est requise. Une grande partie des prairies sont par conséquent fauchées après le 15 juillet et le foin est acheminé en plaine pour l’alimentation du bétail en hiver. Les routes d’accès peu nombreuses ne permettent pas d’atteindre toutes les parcelles; leur foin est emmailloté dans des bâches et transporté par hélicoptère.

description: We show how the interference between spatially separated states of the center of mass (COM) of a mesoscopic harmonic oscillator can be evidenced by coupling it to a spin and performing solely spin manipulations and measurements (Ramsey Interferometry). We propose to use an optically levitated diamond bead containing an NV center spin. The nano-scale size of the bead makes the motional decoherence due to levitation negligible. The form of the spin-motion coupling ensures that the scheme works for thermal states so that moderate feedback cooling suffices. No separate control or observation of the COM state is required and thereby one dispenses with cavities, spatially resolved detection and low mass-dispersion ensembles. The controllable relative phase in the Ramsey interferometry stems from a gravitational potential difference so that it uniquely evidences coherence between states which involve the whole nano-crystal being in spatially distinct locations.

description: There are strong indications that the process of conversion of a neutron star into a strange quark star proceeds as a strong deflagration implying that in a few milliseconds almost the whole star is converted. Starting from the three-dimensional hydrodynamic simulations of the combustion process which provide the temperature profiles inside the newly born strange star, we calculate for the first time the neutrino signal that is to be expected if such a conversion process takes place. The neutrino emission is characterized by a luminosity and a duration that is typical for the signal expected from protoneutron stars and represents therefore a powerful source of neutrinos which could be possibly directly detected in case of events occurring close to our Galaxy. We discuss moreover possible connections between the birth of strange stars and explosive phenomena such as supernovae and gamma-ray-bursts.

title: LEVELS OF BACTERICIDAL PROTEINS IN THE BLOOD AND PERITONEAL EXUDATE IN RATS WHILE MODELING PURULENT AND ASEPTIC PERITONITIS

description: The article presents the results of the study of the concentrations of two proteins of lactoferrin and lysozyme in the blood serum and peritoneal exudate of rats when simulating purulent or aseptic peritonitis in them. Aseptic peritonitis was modeled by intraperitoneal injection of carrageenan, while purulent peritonitis was simulated by injecting monoculture of gram-positive (Staphylococcus aureus, Streptococcus pyogenes in doses of 108 microbial cells) and gram-negative bacteria (Proteus vulgaris, Pseudomonas aeruginosa, Klebsiella oxytoca in doses of 107 microbial cells) with carrageenan. It has been established that when a rat is infected with a monoculture of bacteria, purulent peritonitis of varying severity develops, and in the blood and peritoneal fluid of rats concentrations of lactoferrin and lysozyme are increased, the level of the proteins in the peritoneal exudate being about 1,5 times higher than in their own serum. In the serum of rats, the levels of lactoferrin and lysozyme were always higher with bacterial peritonitis than with aseptic peritonitis. 2-3 days after the infection, it is the level of lactoferrin, but not lysozyme, in the peritoneal fluid of rats that allows differentiating gram-positive abdominal infection from gram-negative one. Determining the lactoferrin and lysozyme by express method in two biological fluids and calculating the ratio of the concentrations of lactoferrin and lysozyme in the blood and the peritoneal fluid, it is possible with a certain degree of probability from the first days of abdominal infection to suggest the nature of bacterial contamination of the abdominal cavity. Key words: laboratory rats, purulent peritonitis, aseptic peritonitis, lactoferrin, lysozyme, determination of peritoneal fluid in blood.

description: We present a dynamical model for the double torsion pendulum nicknamed PETER, where one torsion pendulum hangs in cascade, but off-axis, from the other. The dynamics of interest in these devices lies around the torsional resonance, that is at very low frequencies (mHz). However, we find that, in order to properly describe the forced motion of the pendulums, also other modes must be considered, namely swinging and bouncing oscillations of the two suspended masses, that resonate at higher frequencies (Hz). Although the system has obviously 6+6 Degrees of Freedom, we find that 8 are sufficient for an accurate description of the observed motion. This model produces reliable estimates of the response to generic external disturbances and actuating forces or torques. In particular, we compute the effect of seismic floor motion (tilt noise) on the low frequency part of the signal spectra and show that it properly accounts for most of the measured low frequency noise.

description: We report here the growth and characterization of functional oxide nanowire of hole doped manganite of La0.5Sr0.5MnO3 (LSMO). We also report four probe electrical resistance measurement of single nanowire of LSMO (diameter ~ 45nm) using FIB fabricated electrodes. The wires were fabricated by hydrothermal method using autoclave at a temperature of 270 oC. The elemental analysis and physical property like electrical resistivity were studied at individual nanowire level. The quantitative determination of Mn valency and elemental mapping of constituent elements was done by using Electron Energy Loss Spectroscopy (EELS) in the Scanning Transmission Electron Microscopy (STEM) mode. We addressed the important issue of whether as a result of size reduction the nanowires can retain the desired composition, structure and physical properties. The nanowires used were found to have a ferromagnetic transition (TC) at around 325 K which is very close to the bulk value of around 330 K found in single crystal of the same composition confirming that the functional behavior is likely to be retained even after size reduction of the nanowires to a diameter of 45 nm. The electrical resistivity shows insulating behavior within the temperature range measured, which is very much similar to the bulk system.

description: We present a numerical analysis of the lateral movement and equilibrium radial positions of red blood cells (RBCs) with major diameter of 8 $μ$m under a Newtonian fluid in a circular channel with 50-$μ$m diameter. Each RBC, modelled as a biconcave capsule whose membrane satisfies strain-hardening characteristics, is simulated for different Reynolds numbers $Re$ and capillary numbers $Ca$, the latter of which indicate the ratio of the fluid viscous force to the membrane elastic force. The effects of initial orientation angles and positions on the equilibrium radial position of an RBC centroid are also investigated. The numerical results show that depending on their initial orientations, RBCs have bistable flow modes, so-called rolling and tumbling motions. Most RBCs have a rolling motion. These stable modes are accompanied by different equilibrium radial positions, where tumbling RBCs are further away from the channel axis than rolling ones. The inertial migration of RBCs is achieved by alternating orientation angles, which are primarily affected by the initial orientation angles. Then the RBCs assume the aforementioned bistable modes during the migration, followed by further migration to the equilibrium radial position at much longer time periods. The power (or energy dissipation) associated with membrane deformations is introduced to quantify the state of membrane loads. The energy expenditures rely on stable flow modes, the equilibrium radial position of RBC centroids, and the viscosity ratio between the internal and external fluids.

description: In this paper, we focus on buffer management of multi-queue QoS switches in which packets of different values are segregated in different queues. Our model consists of $m$ queues and $m$ packet values $0 < v_{1} < v_{2} < ... < v_{m}$. Recently, Al-Bawani and Souza [IPL 113(4), pp.145-150, 2013] presented an online algorithm GREEDY for buffer management of multi-queue QoS switches with class segregation and showed thatif $m$ queues have the same size, then the competitive ratio of GREEDY is $1+r$, where $r=\max_{1 \leq i \leq m-1} v_{i}/v_{i+1}$. In this paper, we precisely analyze the behavior of GREEDY and show that it is $(1+r)$-competitive for the case that $m$ queues do not necessarily have the same size.
