description: The study aims to address issues related to valuing women entrepreneurship in the informal economy in Bangladesh. To achieve the above objective, both qualitative and quantitative methods have been used. The author reviewed several articles, research reports, and included face to face in-depth interviews of fifteen entrepreneurs. Moreover, the applied five-point Likert scale questionnaire responded 100 random entrepreneurs from the rural areas of Bangladesh to recognize the barriers in accessing financial institutions and figure out how financial inclusions can contribute more in the informal economy. The results of this study suggest that complicated loans process, high-interest rates, absence of a life skills program, lack of financial freedom for women and property rights, entrepreneurial paradox, absence of collaterals, financial institutions negligence, mismanagement of loans, lack of interactions with local successful entrepreneur and imbalance of family and professional promise are the major barriers in accessing financial institutions in Bangladesh. In addition, financial inclusions are required to bring about changes in their lives. The results of the study will help Bangladesh and other developing countries break down the barriers for women entrepreneurs and develop the business opportunities created by women. In this regard, future research will anticipate both urban and rural areas, with a larger sample and quantitative studies will be conducted.

description:

This paper investigates John Donne’s rhetorical strategies and lyrical outcomes in the light of the increasing scepticism, following the crisis of the century-old epistemological and religious framework undermined by the Reform and the new science. It focuses, in particular, on the recurring use of paradox in the profane context of Songs and Sonnets, which shows how Donne draws upon the  religious discourse preserving  its ‘sacred’ form but adapting it to secular contents and persuasive purposes, devoid of any orthodox transcendence. Moreover, the analysis of Donne’s religious paradoxes reveals the poet’s will to compete with the religious authority by mimicking its argumentative style and its limit-expressions (according to Ricoeur’s definition), in order to build and defend his own ‘poetical truth’. Finally, the paper underlines how Donne’s poetry anticipates one of the main features of modern secularization: the role of the arts (poetry included) as the only possible fictional shelter able to compensate for the loss of religious faith.

Reductions in finite-dimensional quantum mechanics: from symmetries to operator algebras and beyond

description: The idea that symmetries simplify or reduce the complexity of a system has been remarkably fruitful in physics, and especially in quantum mechanics. On a mathematical level, symmetry groups single out a certain structure in the Hilbert space that leads to a reduction. This structure is given by the irreducible representations of the group, and in general it can be identified with an operator algebra (a.k.a. C*-algebra or von Neumann algebra). The primary focus of this thesis is the extension of the framework of reductions from symmetries to operator algebras, and its applications in finite-dimensional quantum mechanics. Finding the irreducible representations structure is the principal problem when working with operator algebras. We will therefore review the representation theory of finite-dimensional operator algebras and elucidate this problem with the help of two novel concepts: minimal isometries and bipartition tables. One of the main technical results that we present is the Scattering Algorithm for analytical derivations of the irreducible representations structure of operator algebras. For applications, we will introduce a symmetry-agnostic approach to the reduction of dynamics where we circumvent the non-trivial task of identifying symmetries, and directly reduce the dynamics generated by a Hamiltonian. We will also consider quantum state reductions that arise from operational constraints, such as the partial trace or the twirl map, and study how operational constraints lead to decoherence. Apart from that, we will extend the idea of reduction beyond operator algebras to operator systems, and formulate a quantum notion of coarse-graining that so far only existed in classical probability theory. We will also characterize how the uncertainty principle transitions to the classical regime under coarse-grained measurements and discuss the implications in a finite-dimensional setting.

description: В статье рассматривается процесс становления и развития гражданского законодательства в России в XI - начале XX вв. На основе анализа соответствующих нормативных правовых актов обосновывается тот факт, что законодательство, регламентирующее нормы гражданского права, отражало сложившиеся в обществе принципы сословного и гендерного, а со временем также национального и религиозного неравенства. Несмотря на то, что с течением времени гражданское законодательство в определенной степени отразило некоторые новеллы буржуазного права, в нем, тем не менее, сохранилось еще очень много черт феодального права - прав-привилегий, пронизанных идеей сословности. В целом в таком виде отечественное гражданское законодательство продолжало действовать до начала XX в., а его трансформация произошла уже после распада Российской империи и связана с созданием Советского государства.

description: We present the results of gravitational direct $N$-body simulations using the Graphics Processing Unit (GPU) on a commercial NVIDIA GeForce 8800GTX designed for gaming computers. The force evaluation of the $N$-body problem is implemented in ``Compute Unified Device Architecture'' (CUDA) using the GPU to speed-up the calculations. We tested the implementation on three different $N$-body codes: two direct $N$-body integration codes, using the 4th order predictor-corrector Hermite integrator with block time-steps, and one Barnes-Hut treecode, which uses a 2nd order leapfrog integration scheme. The integration of the equations of motions for all codes is performed on the host CPU. We find that for $N > 512$ particles the GPU outperforms the GRAPE-6Af, if some softening in the force calculation is accepted. Without softening and for very small integration time steps the GRAPE still outperforms the GPU. We conclude that modern GPUs offer an attractive alternative to GRAPE-6Af special purpose hardware. Using the same time-step criterion, the total energy of the $N$-body system was conserved better than to one in $10^6$ on the GPU, only about an order of magnitude worse than obtained with GRAPE-6Af. For $N \apgt 10^5$ the 8800GTX outperforms the host CPU by a factor of about 100 and runs at about the same speed as the GRAPE-6Af.

description: Growing individualization of products up to lot-size-1 and high volatility of product mixes lead to new challenges in the manufacturing domain, including the need for frequent reconfiguration of the system and reacting to changing orders. Thus, apart from functional aspects, safety aspects of the production system as well as product quality assurance aspects must be addressed for flexible and reconfigurable manufacturing systems at runtime. To cope with the mentioned challenges, we present an integrated model-based approach SQUADfps (machine Safety and product QUAlity for flexible proDuction systems) to support the automatic conduct of the risk assessment of flexible production scenarios in terms of safety as well as the process-FMEA to ensure that the requirements w.r.t. the quality of the production process and the resulting product are met. Our approach is based on a meta-model which captures all information needed to conduct both risk assessment and process-FMEA dynamically during the runtime, and thus enables flexible manufacturing scenarios with frequent changes of the production system and orders up to a lot-size of one while guaranteeing safety and product quality requirements. The automatically generated results will assist human in making further decisions. To demonstrate the feasibility of our approach, we apply it to a case study.

description: We build a sequence of empirical measures on the space D(R_+,R^d) of R^d-valued càdlàg functions on R_+ in order to approximate the law of a stationary R^d-valued Markov and Feller process (X_t). We obtain some general results of convergence of this sequence. Then, we apply them to Brownian diffusions and solutions to Lévy driven SDE's under some Lyapunov-type stability assumptions. As a numerical application of this work, we show that this procedure gives an efficient way of option pricing in stochastic volatility models.

description: В статье рассматривается историческое развитие канадской модели федерализма, особое внимание уделяется правовому регулированию отношений канадской федерации и франкоязычной провинции Квебек, направленному на предотвращение сецессии. Краткий исторический обзор становления канадской федерации позволяет автору сделать вывод об ассиметричной модели федерализма, позволяющей федеральному правительству учитывать общественные интересы населения провинции и вырабатывать различные правовые механизмы предотвращения сецессии. Данные механизмы условно могут быть разделены на две группы: во первых, допускающие сецессию, но направленные на ее сдерживание, посредством закрепления определенной процедуры выхода, и во вторых, направленные на предоставление региону дополнительных полномочий в таких принципиальных для населения сферах, как языковая и иммиграционная политика, финансы и бюджет, внешнеполитическая деятельность и другие, обеспечивающие эффективное взаимодействие федерации и провинции. Отмечаются как положительные аспекты применения данных механизмов, обеспечившие уменьшение уровня сепаратизма в квебекском обществе, так и нерешенные проблемы, связанные необходимостью завершения правовой регламентации конституционного статуса Квебека.

The future of Soviet domestic reform : an analysis of three sovietologists' views
Creators: name: Bruyneel, Stephen Alan
Publisher: name: University of British Columbia
Year: 2010

description: This thesis had two related purposes: to compare, contrast and critique three scholars' views of the Soviet domestic reform process, and to use these analyses as the means by which to examine the emerging Soviet domestic reform program. The arguments of Stephen F. Cohen, Timothy J. Colton and Richard Pipes served as the primary subject matter of this thesis, with their individual views determined by a critical analysis of the writing which each has recently done on this subject. Investigated in particular was each individuals' interpretation of the reform process, its component parts and the kind of change that was expected to be involved in any new domestic reforms. The final chapter dealing with the contemporary Soviet situation relied upon as much primary source material as possible in an attempt to provide an accurate picture of the state of affairs within the country at this time. The results of my analysis indicate that Richard Pipes' interpretations and conclusions do not receive much support from either Soviet history or the contemporary situation within the country. His one dimensional view of Soviet elite interests and his "crisis/reform" theory of Soviet reform were found to be generally unsubstantiated. Stephen Cohen's arguments, on the other hand, received a good deal of support, especially with regards to his emphasis on the probability of moderate change and the existence of reformist and conservative constituencies within the Soviet Union, constituencies which do appear to have been involved in the domestic reform process. At the same time, however, the terminology which he employed to describe the reform process was found to be somewhat problematic. Timothy Colton's arguments, finally, were also found to have a good deal of efficacy, especially with respect to his view of the country's new generation of political leadership and the role that it would play in the reform process. In conclusion, the new domestic reform program itself was found to be indicative of generally moderate economic and political change, change that was embraced for the moat part by a good segment of the new leadership, but which had found significant resistance at the lower levels of the bureaucracy and among the working class.

description: In this article, we introduce a framework for entanglement quantification of photon pairs represented by two-qubit Werner states.

For various settings, numerical simulations were performed to evaluate the efficiency of the framework.

description: We studied experimentally the role of phonon dimensionality on electron-phonon (e-p) interaction in thin copper wires evaporated either on suspended silicon nitride membranes or on bulk substrates, at sub-Kelvin temperatures. The power emitted from electrons to phonons was measured using sensitive normal metal-insulator-superconductor (NIS) tunnel junction thermometers. Membrane thicknesses ranging from 30 nm to 750 nm were used to clearly see the onset of the effects of two-dimensional (2D) phonon system. We observed for the first time that a 2D phonon spectrum clearly changes the temperature dependence and strength of the e-p scattering rate, with the interaction becoming stronger at the lowest temperatures below $\sim$ 0.5 K for the 30 nm membranes.

description: The statistics of Lagrangian particles in turbulent flows is considered in the framework of a simple vortex model. Here, the turbulent velocity field is represented by a temporal sequence of Burgers vortices of different circulation, strain, and orientation. Based on suitable assumptions about the vortices' statistical properties, the statistics of the velocity increments is derived. In particular, the origin and nature of small-scale intermittency in this model is investigated both numerically and analytically.

description: A class of three-dimensional initial data characterized by uniformly large vorticity is considered for the Euler equations of incompressible fluids. The fast singular oscillating limits of the Euler equations are studied for parametrically resonant cylinders. Resonances of fast swirling Beltrami waves deplete the Euler nonlinearity. The resonant Euler equations are systems of three-dimensional rigid body equations, coupled or not. Some cases of these resonant systems have homoclinic cycles, and orbits in the vicinity of these homoclinic cycles lead to bursts of the Euler solution measured in Sobolev norms of order higher than that corresponding to the enstrophy.
Kelvon-roton instability of vortex lines in dipolar Bose-Einstein condensates

description: The physics of vortex lines in dipolar condensates is studied. Due to the nonlocality of the dipolar interaction, the 3D character of the vortex plays a more important role in dipolar gases than in typical short-range interacting ones. In particular, the dipolar interaction significantly affects the stability of the transverse modes of the vortex line. Remarkably, in the presence of a periodic potential along the vortex line, a roton minimum may develop in the spectrum of transverse modes. We discuss the appropriate conditions at which this roton minimum may eventually lead to an instability of the straight vortex line, opening new scenarios for vortices in dipolar gases.

description: This article explores the role of narrative structures and contextual information in the development and implementation of digital interactive 3D testimonies. Based on considerations associated with other testimonial formats and the discourse surrounding them, it will be argued that the conceptual nature of digital interactive 3D testimonies leads to the circumstance that they lack a coherent original narrative when reduced to their interactive elements. Instead, individual audience decisions could lead to the construction of different individual narratives. However, this paper will show that this is not necessarily the outcome for all forms of interaction. Instead, multiple different scenarios are imaginable, varying greatly in the quantity and depth of interaction between testimony and audience. The provision of contextual information may further the goal of enabling audiences to independently interact with a digital interactive 3D testimony and, thus, enhance the overall experience and the likelihood of individual narratives emerging. Overall, these findings are meant to assist the future development and implementation of digital interactive 3D testimonies, and also to provide new theoretical insights into the format for researchers involved in the field of oral history.
Cities in the international system
Creators: name: Winchester, David J.
Publisher: name: University of British Columbia
Year: 2010

description: Municipal actions aimed at promoting local economic development through trade may in certain cases have become sufficiently developed to warrant consideration of municipal governments as actors in the international system. This paper analyzes that possibility by describing the direction of ongoing changes in the international system and assessing the potential for political conflict between city and state. Because the nascent quality of the hypothesized conflict precludes a direct hypothesis-testing methodology, the aim is rather to juxtapose the conflicting logics of the state system and the evolving global economic system to which civic governments must simultaneously conform. Recent work in urban geography and economics has hypothesized that geographical and economic linkages have created international systems of cities which articulate the expansion of the capitalist-dominated world economic system. This paper shows how changes in the global economy are affecting the nature and role of cities within these international subsystems. The analysis posits that the changing international economic environment may be altering the relationship between cities and the states in which they are imbedded. While it is not suggested that a formal devolution of power to municipalities is likely, it is suggested that structural requirements for economic development may be pushing national governments in the direction of removing themselves somewhat from the sphere of international economic relations. The case of the Vancouver municipal government's increasingly proactive stance in the development of commercial links with China is used to illustrate the contention that the power of municipal governments to determine the features of many international relationships is beginning to increase.

description: This paper provides the first analysis on the feasibility of Return-Oriented Programming (ROP) on RISC-V, a new instruction set architecture targeting embedded systems. We show the existence of a new class of gadgets, using several Linear Code Sequences And Jumps (LCSAJ), undetected by current Galileo-based ROP gadget searching tools. We argue that this class of gadgets is rich enough on RISC-V to mount complex ROP attacks, bypassing traditional mitigation like DEP, ASLR, stack canaries, G-Free, as well as some compiler-based backward-edge CFI, by jumping over any guard inserted by a compiler to protect indirect jump instructions. We provide examples of such gadgets, as well as a proof-of-concept ROP chain, using C code injection to leverage a privilege escalation attack on two standard Linux operating systems. Additionally, we discuss some of the required mitigations to prevent such attacks and provide a new ROP gadget finder algorithm that handles this new class of gadgets.

description: The layered structure and the rheological properties of anti-wear films, generated in a rolling/sliding contact from lubricants containing zinc dialkyldithiophosphate (ZDTP) and/or molybdenum dialkyldithiocarbamate (MoDTC) additives, have been studied by dynamic nanoindentation experiments coupled with a simple modelling of the stiffness measurements. Local nano-friction experiments were conducted with the same device in order to determine the evolution of the friction coefficient as a function of the applied pressure for the different lubricant formulations. For the MoDTC film, the applied pressure in the friction test remains low (<0.5 GPa) and the apparent friction coefficient is high ($μ$ > 0.4). For the tribofilms containing MoDTC together with ZDTP, which permits the applied pressure to increase up to a few GPa through some accommodation process, a very low friction domain appears (0.01 < $μ$ < 0.05), located a few nanometers below the surface of the tribofilm. This low friction coefficient is attributed to the presence of MoS2 planes sliding over each other in a favourable configuration obtained when the pressure is sufficiently high, which is made possible by the presence of ZDTP.

description: The topological characterization of nonequilibrium topological matter is highly nontrivial because familiar approaches designed for equilibrium topological phases may not apply. In the presence of crystal symmetry, Floquet topological insulator states cannot be easily distinguished from normal insulators by a set of symmetry eigenvalues at high symmetry points in the Brillouin zone. This work advocates a physically motivated, easy-to-implement approach to enhance the symmetry analysis to distinguish between a variety of Floquet topological phases. Using a two-dimensional inversion-symmetric periodically-driven system as an example, we show that the symmetry eigenvalues for anomalous Floquet topological states, of both first-order and second-order, are the same as for normal atomic insulators. However, the topological states can be distinguished from one another and from normal insulators by inspecting the occurrence of stable symmetry inversion points in their microscopic dynamics. The analysis points to a simple picture for understanding how topological boundary states can coexist with localized bulk states in anomalous Floquet topological phases.

description: The silicon pixel sensor is the core component of the vertex detector for the Circular Electron Positron Collider~(CEPC). The JadePix3 is a full-function large-size CMOS chip designed for the CEPC vertex detector. To test all the functions and the performance of this chip, we designed a test system based on the IPbus framework. The test system controls the parameters and monitors the status of the pixel chip. By integrating the jumbo frame feature into the IPbus suite, the block read/write speed is further extended in order to meet the specifications of the JadePix3. The robustness, scalability, and portability of this system have been verified by pulse test, cosmic test and laser test in the laboratory. This paper summarizes the DAQ and control system of the JadePix3 and presents the first results of the tests.

Necessary and Sufficient Conditions for the Trumping Relation
Creators: name: Turgut, S.

Year: 2007
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Entanglement catalysis allows one to convert certain entangled states into others by the temporary involvement of another entangled state (so-called catalyst), where after the conversion the catalyst is returned to the same state. For bipartite pure entangled states that can be transformed in this way with unit probability, the respective Schmidt coefficients are said to satisfy the trumping relation, a mathematical relation which is an extension of the majorization relation. This article provides all necessary and sufficient conditions for the trumping relation in terms of the Schmidt coefficients. The coefficients should satisfy strict inequalities for the entropy of entanglement and for power means excluding the special power 1.

Cubic Vertices for N=1 Supersymmetric Massless Higher Spin Fields in Various Dimensions

description: Using the BRST approach to higher spin field theories we develop a generic technique for constructing the cubic interaction vertices for N=1 supersymmetric massless higher spin fields on four, six and ten dimensional flat backgrounds. Such an approach allows formulation of the equations for cubic vertices including bosonic and fermionic higher spin fields, and the problem of finding the vertices is reduced to finding the consistent solutions to these equations. As a realization of this procedure, we present the particular solutions for the vertices where the fields obey some off-shell constraints. It is shown that the supersymmetry imposes additional constraints on the vertices and singles out a particular subclass of the solutions. As a concrete application of the generic scheme, we consider supersymmetric Yang-Mills-like systems in four, six and ten dimensions where the higher spin fields transform under some internal symmetry group, as well as supergravity-like systems in the same dimensions.

Experimental observation of structural crossover in binary mixtures of colloidal hard spheres

description: Using confocal-microscopy we investigate the structure of binary mixtures of colloidal hard spheres with size ratio q=0.61. As a function of the packing fraction of the two particle species, we observe a marked change of the dominant wavelength in the pair correlation function. This behavior is in excellent agreement with a recently predicted structural crossover in such mixtures. In addition, the repercussions of structural crossover on the real-space structure of a binary fluid are analyzed. We suggest a relation between crossover and the lateral extension of networks containing only equally sized particles that are connected by nearest neighbor bonds. This is supported by Monte-Carlo simulations which are performed at different packing fractions and size ratios.

description: Flavour Changing Neutral Current decays of the $B$-meson are a very useful tool for studying possible physics scenarios beyond the Standard Model (SM), where of the many FCNC modes radiative, purely leptonic and semi-leptonic decays of the $B$-meson are relatively clean tests. Within this context the BELLE collaboration has searched for the $B \to K_1(1270) γ$ process and provided an upper bound on this decay. In this work we have used this upper bound in studying the angular coorelations for the related semi-leptonic decay mode $B \to K_1(1270) (\to ρK) \ell^+ \ell^-$, where we have used the form factors that have already been estimated for the $B \to K_1(1270) γ$ mode. Note that the additional form factors that are required were calculated using the Large Energy Effective Theory (LEET).

description: We have measured the Balmer-series x-rays of kaonic $^4$He atoms using novel large-area silicon drift x-ray detectors in order to study the low-energy $\bar{K}$-nucleus strong interaction. The energy of the $3d \to 2p$ transition was determined to be 6467 $\pm$ 3 (stat) $\pm$ 2 (syst) eV. The resulting strong-interaction energy-level shift is in agreement with theoretical calculations, thus eliminating a long-standing discrepancy between theory and experiment.

A High Robustness and Low Cost Model for Cascading Failures

Year: 2007
Subjects: subject: Physics and Society (physics.soc-ph)

description: We study numerically the cascading failure problem by using artificially created scale-free networks and the real network structure of the power grid. The capacity for a vertex is assigned as a monotonically increasing function of the load (or the betweenness centrality). Through the use of a simple functional form with two free parameters, revealed is that it is indeed possible to make networks more robust while spending less cost. We suggest that our method to prevent cascade by protecting less vertices is particularly important for the design of more robust real-world networks to cascading failures.

We identify the origin of these lines as coming from the surface of the donor star, thereby providing the first estimate of the mass function of f(M_1)>=0.22M_sun. Rotational broadening estimates together with assumptions for the mass donor give 0.07

description: The paper presents a framework for fire extinguishing in an urban scenario by a team of aerial and ground robots. The system was developed to address Challenge 3 of the 2020Mohamed Bin Zayed International Robotics Challenge (MBZIRC). The challenge required to autonomously detect, locate and extinguish fires on different floors of a building, as well as in its surroundings. The multi-robot system developed consists of a heterogeneous robot team of up to three Unmanned Aerial Vehicles (UAV) and one Unmanned Ground Vehicle (UGV). We describe the main hardware and software components for UAV and UGVplatforms and also present the main algorithmic components of the system: a 3D LIDAR-based mapping and localization module able to work in GPS-denied scenarios; a global planner and a fast local re-planning system for robot navigation; infrared-based perception and robot actuation control for fire extinguishing; and a mission executive and coordination module based on Behavior Trees. The paper finally describes the results obtained during the competition, where the system worked fully autonomously and scored in all the trials performed. The presented system ended in 7th position out of 20 teams in the Challenge3 competition and in 5th position (out of 17 teams) in the Challenge 3 entry to the Grand Finale (Grand Challenge) of MBZIRC 2020 competition.

description: De Sitter solutions play an important role in cosmology because the knowledge of unstable de Sitter solutions can be useful to describe inflation, whereas stable de Sitter solutions are often used in models of late-time acceleration of the Universe. The Einstein-Gauss-Bonnet gravity cosmological models are actively used both as inflationary models and as dark energy models. To modify the Einstein equations one can add a nonlinear function of the Gauss-Bonnet term or a function of the scalar field multiplied on the Gauss-Bonnet term. The effective potential method essentially simplifies the search and stability analysis of de Sitter solutions, because the stable de Sitter solutions correspond to minima of the effective potential.
