description: The aim of this work is to solve problems concerning the bank information system of commercial banks, where a big emphasis is laid on the security of the information system. At the present time, not only bank specialists but also top experts in creation and implementation of bank softwares are engaged in the solution of these problems. The paper advances from empiric analyses of the information system security to general theoretical starting-points and theses. It focuses on the problems of data protection by minimalising and/or excluding the possibility of leakage of information and its subsequent misuse, as well as on information security, and defines the levels of security usable in building the information system. Also, it deals with assessing the bank information system through an external audit with the aim to analyse the regularity of operations and reliability of the information system in terms of the criteria required, and through an internal audit, which is an important security component of the information system.

description: Thanks to the remarkable developments of ultrafast science, one of today's challenges is to modify material state by controlling with a light pulse the coherent motions that connect two different phases. Here we show how strain waves, launched by electronic and structural precursor phenomena, determine a macroscopic transformation pathway for the semiconducting-to-metal transition with large volume change in bistable Ti$_3$O$_5$ nanocrystals. Femtosecond powder X-ray diffraction allowed us to quantify the structural deformations associated with the photoinduced phase transition on relevant time scales. We monitored the early intra-cell distortions around absorbing metal dimers, but also long range crystalline deformations dynamically governed by acoustic waves launched at the laser-exposed Ti$_3$O$_5$ surface. We rationalize these observations with a simplified elastic model, demonstrating that a macroscopic transformation occurs concomitantly with the propagating acoustic wavefront on the picosecond timescale, several decades earlier than the subsequent thermal processes governed by heat diffusion.

description: We consider, theoretically and experimentally, the effects of structural disorder, quantum and thermal fluctuations in the magnetic and transport properties of certain ferromagnetic alloys.We study the particular case of UCu2Si(2-x)Ge(x). The low temperature resistivity, rho(T,x), exhibits Fermi liquid (FL) behavior as a function of temperature T for all values of x, which can be interpreted as a result of the magnetic scattering of the conduction electrons from the localized U spins. The residual resistivity, rho(0,x), follows the behavior of a disordered binary alloy. The observed non-monotonic dependence of the Curie temperature, Tc(x), with x can be explained within a model of localized spins interacting with an electronic bath whose transport properties cross-over from ballistic to diffusive regimes. Our results clearly show that the Curie temperature of certain alloys can be enhanced due to the interplay between quantum and thermal fluctuations with disorder.

description: We present a detailed analysis of star formation properties of galaxies in a nearby ($z\sim0.046$) young ($\sim$0.6 Gyr) post-merger cluster system A3376, with a moderate shock front ( $v_{s}\sim$1630 km/s) observed as symmetric radio relics. Exploiting the spectroscopic data from the wide-field OmegaWINGS survey and the associated photometric information, our investigations reveal the plausible effects of the dynamic post-merger environment differing from the putative pre-merger cluster environment. The remnants of the pre-merger relaxed cluster environment are realised through the existence of passive spiral galaxies located in the central regions of the cluster between the two BCGs. We discover A3376 to contain a population of massive $(M_{*}/M_{\odot})>10$) blue regular star-forming spirals in regions of maximum merger shock influence but exhibiting star formation rates similar to those in relaxed clusters at similar epoch. We further discover low-mass (Log $(M_{*}/M_{\odot})\leq 10$) late-type blue PSBs which could either be formed as a result of rapid quenching of low-mass spirals following the shock-induced star formation or due to the intense surge in the ICM pressures at the beginning of the merger. With the possibility of the merger shock affecting high- and low-mass spirals differently, our results bridge the seemingly contradictory results observed in known merging cluster systems so far and establish that different environmental effects are at play right from pre- to post-merger stage.

EC's Common Agricultural Policy Slows Farm Exports

description: How well has the United States done in the European Community (EC) farm commodity market since the Common Agricultural Policy (CAP) was inaugurated in 1962? The record reveals that U.S. commercial sales of farm commodities to the EC grew at less than two-thirds of their growth rate to other countries. EC variable import levies held the rise in exports to the EC of affected U.S. commodities to a modest 23 percent, compared with a 94-percent gain for commodities not subject to the levies. EC internal trade (or "intratrade" as used in this article to identify trade among EC members) in farm commodities increased nearly 2 1/2 times, compared with less than half for EC imports from third countries. Intratrade gains for French grain are of particular concern to the United States. Barring policy changes, EC enlargement with its wider application of restrictive policies poses a significant threat to our farm export growth.

Dynamics of Fluctuation Dominated Phase Ordering: Hard-core Passive Sliders on a Fluctuating Surface

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study the dynamics of a system of hard-core particles sliding downwards on a one dimensional fluctuating interface, which in a special case can be mapped to the problem of a passive scalar advected by a Burgers fluid. Driven by the surface fluctuations, the particles show a tendency to cluster, but the hard-core interaction prevents collapse. We use numerical simulations to measure the auto-correlation function in steady state and in the aging regime, and space-time correlation functions in steady state. We have also calculated these quantities analytically in a related surface model. The steady state auto-correlation is a scaling function of t/L^z, where L is the system size and z the dynamic exponent. Starting from a finite intercept, the scaling function decays with a cusp, in the small argument limit. The finite value of the intercept indicates the existence of long range order in the system. The space-time correlation, which is a function of r/L and t/L^z, is non-monotonic in t for fixed r. The aging auto-correlation is a scaling function of t_1 and t_2 where t_1 is the waiting time and t_2 the time difference. This scaling function decays as a power law for t_2 \gg t_1; for t_1 \gg t_2, it decays with a cusp as in steady state. To reconcile the occurrence of strong fluctuations in the steady state with the fact of an ordered state, we measured the distribution function of the length of the largest cluster. This shows that fluctuations never destroy ordering, but rather the system meanders from one ordered configuration to another on a relatively rapid time scale.
Importance of Battery Recycling & Swapping: The Next Inevitable Step in EV Supply Chain

description: VehiThe purpose of this study is to fathom the importance of battery supply chain including battery swapping and recycling as well as the charging infrastructure as nodes in the electric vehicle (EV) supply chain in India. It also delves into the ways in which Faster Adoption and Manufacturing of Hybrid and Electric Vehicles or FAME II is addressing these issues. One of the key obstacles in the way to the speedy adoption of EVs is range anxiety. A healthy and expanding network of charging infrastructure has a very important role to play in penetration and propagation of E-mobility. Fame II is also committed towards creating charging infrastructure besides providing demand incentive. The problem of battery waste generation which is an obvious fall out of e-mobility adoption is intended to be addressed through battery recycling and battery swapping-both are at a nascent stage in India with significant potential for growth. The study looks into both primary data (gathered through survey) and secondary data (collected from authentic data sources both public and private) sources. The mix of empirical research and direct face-to-face interview with consumers helps to better substantiate our argument. Adoption of E-mobility is unavoidable so is battery waste generation. Battery recycling and battery swapping can be the two technologies that assume enormous importance with the expansion of EV market in India. Range anxiety, another key concern of the potential and present EV owners, can be taken care of by ramping up charging infrastructure-a key area of focus of the Indian Government in its FAME I & II schemes.

The protocol is based on results obtained in paper [Frydryszak et al. (2017)]. This protocol is tested on a 5-qubit superconducting quantum processor called ibmq-ourense provided by the IBM company. We determine the values of entanglement of the Schrödinger cat and the Werner states prepared on this device and compare them with the theoretical ones. In addition, a protocol for determining the entanglement of rank-2 mixed states is proposed. We apply this protocol to the mixed state which consists of two Bell states prepared on the ibmq-ourense quantum device.

description: Genomic information and its associated technologies appear to have the potential to significantly increase agricultural productivity and, hence, contribute to meeting the food security challenges that feeding nine billion people by 2050 presents. The costs of genomic information and the associated implementation technologies continue to fall. Much of the output of genomic-based improvement may not qualify for protection as intellectual property. It also does not suffer from the concerns that have been associated with transgenic technology – GMOs – such as potential risks to human health and the environment, ethical issues and highly concentrated control of the food system. As a result, both the regulatory and trade regimes need not be as rigorous as has been the case for GMOs in some jurisdictions. A regulatory regime that encourages investment in genomics-based agricultural technology and an open trade regime will facilitate the ability of the technology to contribute to global food security.

description: A loop or coupling expansion of a so-called n-particle irreducible (nPI) generating functional provides a well-defined approximation scheme in terms of self-consistently dressed propagators and n-point vertices. A self-consistently complete description determines the functional for arbitrarily high n to a given order in the expansion. We point out an equivalence hierarchy for nPI effective actions, which allows one to obtain a self-consistently complete result in practice. The method is applied to a SU(N) gauge theory with fermions up to four-loop or O(g^6) corrections. For non-equilibrium we discuss the connection to kinetic theory. The leading-order on-shell results in g can be obtained from the three-loop effective action approximation, which already includes in particular all diagrams enhanced by the Landau Pomeranchuk Migdal effect. Furthermore, we compare the effective action approach with Schwinger-Dyson (SD) equations. By construction, SD equations are expressed in terms of loop diagrams including both classical and dressed vertices, which leads to ambiguities of whether classical or dressed ones should be employed at a given truncation order. We point out that these problems are absent using effective action techniques. We show that a wide class of truncations of SD equations cannot be obtained from the nPI effective action. In turn, our results can be used to resolve SD ambiguities of whether classical or dressed vertices should be employed at a given truncation order.

description: This article explores the genesis and implementation of a Caribbean (Jamaican) approach to improving corporate governance (CG) among public bodies. Public bodies (PB) are integral to the success of public management and administration vis-à-vis development and implementation of key policy objectives. There is the need for these state-controlled entities across the Caribbean to be accountable and fully compliant with several statutory requirements. In response to these challenges, the Government of Jamaica has sought to clarify the governance framework within which public bodies must operate by establishing a Corporate Governance Framework for Public Bodies of Jamaica. The article benefits from a mixed methodology of qualitative and quantitative streams of data collection and analysis. The key objectives in presenting these findings are to improve accountability and compliance and to achieve a more efficient and effective public service.

In this reply, we show that this claim contradicts their original paper (Phys. Rev. B 63, 033105 (2001)). We demonstrate that the condition given for the expansion is mathematically incorrect. The correct condition allows to understand the limits of validity of the analytical theory.

description: This article aims to assess recent developments in the Chinese merchandise import sector through retrospective analysis of the main imported products during the 2000-2015 period. The grouping of these trends helps to shed light on the different aspects of the country’s gradual shift towards stimulating private consumption. The findings suggest a focus on a narrower range of machinery products, emphasis on imports of vehicles and aircraft, along with the pursuit of cheaper and more environmentally friendly energy resources. The enhancement of private consumption is further manifest by significant upward trends in the food and beverage import sector.

description: Orthogonal time frequency space (OTFS) is being pursued in recent times as a suitable wireless transmission technology for use in high mobility scenarios. In this work, we propose nonorthogonal multiple acess (NOMA) based OTFS which may be called NOMA-OTFS system and evaluate its performance from system level and link level perspective. The challenge lies in the fact that while OTFS transmission technology is known for its resilience to high mobility conditions, while NOMA is known to yield high spectral efficiency in low mobility scenarios in comparison to orthogonal multiple access (OMA). We present a minimum mean square error (MMSE)- successive interference cancellation (SIC) based receiver for NOMA-OTFS, for which we derive expression for symbol-wise post-processing SINR in order to evaluate system sum spectral efficiency (SE). We develop power allocation schemes to maximize the sum SE in the high-mobility version of NOMA. We further design a realizable codeword level SIC (CWIC) receiver using LDPC codes along with MMSE equalization for evaluating link level performance of such practical NOMA-OTFS system. The system level and link level performance of the proposed NOMA-OTFS system are compared against benchmark OMA-OTFS, OMA-orthogonal frequency division multiplexing (OMA-OFDM) and NOMA-OFDM schemes. From system-level performance evaluation, we observe interestingly that NOMA-OTFS provides higher sum SE than OMA-OTFS. When compared to NOMA-OFDM, we find that outage SE of NOMA-OTFS is improved at the cost of decrease in mean SE. Whereas link-level results show that the developed CWIC based NOMA-OTFS receiver performs significantly better than NOMA-OFDM in terms of block error rate (BLER), goodput and throughput.

description: The spat between the three United States carriers – American, Delta and United Airlines on the one hand and the carriers of the United Arab Emirates on the other — where the former accused the latter of unfair practices buffered by state aid and allegedly practiced under an open skies agreement between the United States and UAE - brought to bear a global inquiry on whether an open skies agreement which gave unlimited rights on market access could result in the erosion of the “ equality of opportunity” to compete embodied in the Chicago Convention. The U.S. carriers alleged that the UAE carriers received zero-interest loans from the UAE government with no arrangements for repayment; grants of land which could be regarded as subsidies; development of massive airports, built and paid for by the state, and very cheap rent facilities and landing charges; low labour rates because the home state bans unions; and low personal and corporate tax rates to promote the growth of business.2 The UAE carriers countered that they had not received subsidies and were not operating into and out of the United States with undercut pricing and therefore were within their rights under the agreement. The 2016 award of the Nobel Prize in economics to two economists for their Theory of Contracts highlights the significance of the theory in its application to open skies agreements, which this article analyses in some detail.
Ionic liquids under confinement: From systematic variations of the ion and pore sizes towards an understanding of structure and dynamics in complex porous carbons

description: We use molecular simulations of an ionic liquid in contact with a range of nanoporous carbons to investigate correlations between ion size, pore size, pore topology and properties of the adsorbed ions. We show that diffusion coefficients increase with the anion size and, surprisingly, with the quantity of adsorbed ions. Both findings are interpreted in terms of confinement: when the in-pore population increases additional ions are located in less confined sites and diffuse faster. Simulations in which the pores are enlarged while keeping the topology constant comfort these observations. The interpretation of properties across structures is more challenging. An interesting point is that smaller pores do not necessarily lead to larger confinement. In this work, the highest degrees of confinements are observed for intermediate pore sizes. We also show a correlation between the quantity of adsorbed ions and the ratio between the maximum pore diameter and the pore limiting diameter.

Galactic Center IRS13E: Colliding Stellar Winds or an Intermediate Mass Black Hole?

description: A small cluster of massive stars residing in the Galactic center, collectively known as IRS13E, is of special interest due to its close proximity to Sgr A* and the possibility that an embedded intermediate-mass black hole (IMBH) binds its member stars. It has been suggested that colliding winds from two member stars, both classified as Wolf-Rayet type, are responsible for the observed X-ray, infrared and radio emission from IRS13E. We have conducted an in-depth study of the X-ray spatial, temporal and spectral properties of IRS13E, based on 5.6 Ms of ultra-deep Chandra observations obtained over 20 years. These X-ray observations show no significant evidence for source variability. We have also explored the kinematics of the cluster members, using Keck near-infrared imaging and spectroscopic data on a 14-yr baseline that considerably improve the accuracy of stars' proper motions. The observations are interpreted using 3-dimensional hydrodynamical simulations of colliding winds tailored to match the physical conditions of IRS13E, leading us to conclude that the observed X-ray spectrum and morphology can be well explained by the colliding wind scenario, in the meantime offering no support for the presence of a putative IMBH. An IMBH more massive than a few $10^3{\rm~M_\odot}$ is also strongly disfavored by the stellar kinematics.

Cavity Growth in Soft Solids

description: Soft polymer-based solid materials can be defined as solid materials with elastic moduli below 1 MPa. In order to obtain such a low modulus while retaining a solid character, all these materials are based on a network of fixed points (crosslinks, physical interactions) keeping together a liquid-like matrix. Since they are not able to flow, very large deformations will lead to failure by fracture or cavitation. We discuss in this paper new experimental data suggesting that the growth of a cavity in a soft nearly elastic solid undergoes a transition from a stress-controlled growth, when the initial cavity size is larger than Gc/E, to an energy-activated growth, when the initial cavity size is smaller than Gc/E. The important material length scale Gc/E represents the ratio between the surface energy necessary to expand the cavity and the elastic modulus. This energy activated growth regime is due to the existence of a metastable solution and significantly increases the apparent cavitation stress for layers thinner than 1000 Gc/E.

description: The understanding of few-nucleon systems at low energies is essential, e.g. for accurate predictions of element abundances in big-bang and stellar fusion. Novel effective field theories, taking only nucleons, or nucleons and pions as explicit degrees of freedom, provide a systematic approach, permitting an estimate of theoretical uncertainties. Basic constants parameterising the short range physics are derived from only a handful of experimental values. The doublet neutron scattering length a_2 of the deuteron is particularly sensitive to a three-nucleon contact interaction, but experimentally known with only 6% accuracy. It can be deduced from the two experimentally accessible parameters of the nd scattering length. We plan to measure the poorly known "incoherent" nd scattering length a_{i,d} with 10^{-3} accuracy, using a Ramsey apparatus for pseudomagnetic precession with a cold polarised neutron beam at PSI. A polarised target containing both deuterons and protons will permit a measurement relative to the incoherent np scattering length, which is know experimentally with an accuracy of 2.4\times 10^{-4}.

description: We reconsider the classic puzzle of why election turnouts are persistently so high even though formal analysis strongly suggests that rational agents should not vote. If we assume that voters are not making systematic mistakes, the most plausible explanation seems to be that agents receive benefits from the act of voting itself. This is very close to assuming the answer, however, and immediately begs the question of why agents feel a warm glow from participating in the electoral process. In this paper, we approach the question from an evolutionary standpoint. We show for a range of situations, that public-spirited agents have an evolutionary advantage over those who are not as public-spirited. We also explore conditions under which this kind of altruistic behavior is disadvantageous to agents. The details depend on the costs of voting, the degree to which different types of agents have different preferences over public policies and the relative proportions of various preference types in the population, but we conclude that evolution may often be a force that causes agents to internalize the benefits their actions confer on others.

description: Moments of generalised parton distributions can be related to off-forward matrix elements of local operators. We calculate a few of the leading twist matrix elements for the pion on the lattice. The simulations are performed using two flavours of dynamical fermions and a range of pion masses from 550 to 1090 MeV. Our lattice spacings and spatial volumes lie in the range 0.07-0.12 fm and (1.6-2.2 fm)^3, respectively. Key features of our investigation are the use of O(a) improved Wilson fermions and non-perturbative renormalisation. We present first results for the two lowest moments of the generalised parton distributions of the pion and compare the pion electromagnetic form factor F_pi to experimental data. Good agreement is found between lattice data and experiment.

description: Are command systems that rest on coercion inherently unstable, and did the Soviet economy collapse for this reason? Postwar evidence is inconsistent with the hypothesis that the Soviet economy was unstable. If it was not unstable, why did it collapse? A repeated game of coordination between a dictator and producers shows that a high level of coercion may yield a stable high–output equilibrium, that the command economy contains a time–consistency problem for central planners, and that a transition to a low state of coercion and performance in which everyone’s income falls may be brought about by rising monitoring costs and the dictator’s loss of reputation. The facts of the Soviet case are consistent with a collapse triggered when the dictator threw in the towel.
