description: We introduce a sufficient and necessary condition for the separability of a specific class of $N$ $d$-dimensional system (qudits) states, namely special generalized Werner state (SGWS): $W^{[d^N]}(v)=(1-v)\frac{I^{(N)}}{d^N}+v|ψ_d^N>=\sum_{i=0}^{d-1}α_i|i... i>$ is an entangled pure state of $N$ qudits system and $α_i$ satisfys two restrictions: (i) $\sum_{i=0}^{d-1}α_iα_i^*=1$; (ii) Matrix $\frac{1}{d}(I^{(1)}+\mathcal{T}\sum_{i\neq j}α_i|i>< j|α_j^*)$, where $\mathcal{T}=\texttt{Min}_{i\neq j}\{1/|α_iα_j|\}$, is a density matrix. Our condition gives quite a simple and efficiently computable way to judge whether a given SGWS is separable or not and previously known separable conditions are shown to be special cases of our approach.

description: Railway systems provide pivotal support to modern societies, making their efficiency and robustness important to ensure. However, these systems are susceptible to disruptions and delays, leading to accumulating economic damage. The large spatial scale of delay spreading typically make it difficult to distinguish which regions will ultimately affected from an initial disruption, creating uncertainty for risk assessment. In this paper, we identify geographical structures that reflect how delay spreads through railway networks. We do so by proposing a graph-based, hybrid schedule and empirical-based model for delay propagation and apply spectral clustering. We apply the model to four European railway systems: the Netherlands, Germany, Switzerland and Italy. We characterize geographical structures in the railway systems of these countries and interpret these regions in terms of delay severity and how dynamically disconnected they are from the rest. The method also allows us to point out important differences between these countries' railway systems. For practitioners, this geographical characterization of railways provide natural boundaries for local decision-making structures and a first-order prioritization on which regions are at risk, given an initial disruption.

description: In this paper, an Empirical Mode Decomposition-based method is proposed for the detection of transformer faults from Dissolve gas analysis (DGA) data. Ratio-based DGA parameters are ranked using their skewness. Optimal sets of intrinsic mode function coefficients are obtained from the ranked DGA parameters. A Hierarchical classification scheme employing XGBoost is presented for classifying the features to identify six different categories of transformer faults. Performance of the Proposed Method is studied for publicly available DGA data of 377 transformers. It is shown that the proposed method can yield more than 90% sensitivity and accuracy in the detection of transformer faults, a superior performance as compared to conventional methods as well as several existing machine learning-based techniques.

description: Teeming within pollen provisions are diverse communities of symbiotic microbes, which provide a variety of benefits to bees. Microbes themselves may represent a major dietary resource for developing bee larvae. Despite their apparent importance in sustaining bee health, evidence linking pollen-borne microbes to larval health is currently lacking. We examined the effects of microbe-deficient diets on the fitness of larval mason bees. In a series of diet manipulations, microbe-rich maternally collected pollen provisions were replaced with increasing fractions of sterilized, microbe-deficient pollen provisions before being fed to developing larvae. Convergent findings from amino acid and fatty acid trophic biomarker analyses revealed that larvae derived a substantial amount of nutrition from microbial prey and occupied a significantly higher trophic position than that of strict herbivores. Larvae feeding on increasingly sterile diets experienced significant adverse effects on growth rates, biomass and survivorship. When completely deprived of pollen-borne microbes, larvae consistently exhibited marked decline in fitness. We conclude that microbes associated with aged pollen provisions are central to bee health, not only as nutritional mutualists, but also as a major dietary component. In an era of global bee decline, the conservation of such bee–microbe interactions may represent an important facet of pollinator protection strategies.

description: Identifying academic plagiarism is a pressing problem, among others, for research institutions, publishers, and funding organizations. Detection approaches proposed so far analyze lexical, syntactical, and semantic text similarity. These approaches find copied, moderately reworded, and literally translated text. However, reliably detecting disguised plagiarism, such as strong paraphrases, sense-for-sense translations, and the reuse of non-textual content and ideas, is an open research problem. The thesis addresses this problem by proposing plagiarism detection approaches that implement a different concept: analyzing non-textual content in academic documents, specifically citations, images, and mathematical content. To validate the effectiveness of the proposed detection approaches, the thesis presents five evaluations that use real cases of academic plagiarism and exploratory searches for unknown cases. The evaluation results show that non-textual content elements contain a high degree of semantic information, are language-independent, and largely immutable to the alterations that authors typically perform to conceal plagiarism. Analyzing non-textual content complements text-based detection approaches and increases the detection effectiveness, particularly for disguised forms of academic plagiarism. To demonstrate the benefit of combining non-textual and text-based detection methods, the thesis describes the first plagiarism detection system that integrates the analysis of citation-based, image-based, math-based, and text-based document similarity. The system's user interface employs visualizations that significantly reduce the effort and time users must invest in examining content similarity.

The physics of strong magnetic fields in neutron stars

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this paper we present a new result, namely that the primal magnetic field of the collapsed core during a supernova explosion will, as a result of the conservation of magnetic flux, receive a massive boost to more than 90 times its original value by the Pauli paramagnetization of the highly degenerate relativistic electron gas just after the formation of the neutron star. Thus, the observed super-strong magnetic field of neutron stars may originate from the induced Pauli paramagnetization of the highly degenerate relativistic electron gas in the interior of the neutron star. We therefore have an apparently natural explanation for the surface magnetic field of a neutron star.

description: We calculate the baryon magnetic moments using covariant Chiral Perturbation Theory ($χ$PT) within the Extended-on-mass-shell (EOMS) renormalization scheme. By fitting the two available low-energy constants (LECs), we improve the Coleman-Glashow description of the data when we include the leading SU(3) breaking effects coming from the lowest-order loops. This success is in dramatic contrast with previous attempts at the same order using Heavy Baryon (HB) $χ$PT and covariant Infrared (IR) $χ$PT. We also analyze the source of this improvement with particular attention on the comparison between the covariant results.

description: We make the first steps towards an understanding of the ergodic properties of a rational map defined over a complete algebraically closed non-archimedean field. For such a rational map R, we construct a natural invariant probability measure m_R which reprensents the asymptotic distribution of preimages of non-exceptional point. We show that this measure is exponentially mixing, and satisfies the central limit theorem. We prove some general bounds on the metric entropy of m_R, and on the topological entropy of R. We finally prove that rational maps with vanishing topological entropy have potential good reduction.

description: Successful deposition of thick copper coatings on low carbon steel is a challenge for the Cold Gas Dynamic Spray (CGDS) process if one is to avoid the use of helium as the process gas for the initial pre-coat layer. The issue stems from the presence of accumulated residual stresses, which causes delamination of the weakly bonded coating. Even after exploring different deposition parameters, several copper powders and various steel substrate preparations, copper coating delamination still occurs. The purpose of the current study is to produce copper coatings using only nitrogen as the process gas, while avoiding delamination of the deposited material. To this end, the current work focuses on the study of the effect of steel substrate temperature on particle deposition and adhesion processes. Steel substrates were heated to temperatures between 25°C and 600°C using induction heating and laser. Once the substrate reached the desired temperature, three different copper particle sizes were deposited using the CGDS process. Individual particle impact tests (wipe-tests) were performed to characterize bonded particles and craters from rebounded particles. Further analysis was performed by extracting particles from the surface to understand the effect of substrate temperature and particle size on the particle/substrate deformation and bonding processes. Mechanical adhesion prediction modeling at substrate preheated was also performed to obtain a greater understanding of the bonding mechanism. This prediction is in order to compare with the coating developed with a bond layer coating with helium as process gas and then build the rest of the coating with nitrogen. The experimental results show a significant trend as the substrate temperature increases, indicating proper conditions for enhanced adhesion.

description: Op 12 maart 2019 bestond het wereldwijde web precies dertig jaar. Nadat de leidinggevende zijn fiat had gegeven aan het voorstel van Tim Berners-Lee met de woorden “vague, but exciting”, kon de bedenker en grondlegger van het web aan de slag. Op 6 augustus 1991 kwam de eerste website online bij CERN in Zwitserland. De tweede website kwam op het web bij het SLAC National Accelerator Laboratory in de VS. De pagina van Kees Huyser Download originele afbeelding Verrassend genoeg werd de derde website van de wereld in Nederland in februari 1992 gepubliceerd door het Nationaal Instituut voor Subatomaire Fysica (Nikhef). Omdat deze organisatie ook de vierde website van de wereld bouwde, kunnen we stellen dat er een moment in de geschiedenis van het wereldwijde web is geweest dat de helft van het WWW Nederlands was. De eerste Nederlandse webmaster was Willem van Leeuwen. Kees Huyser van het Nikhef was de tweede webmaster van Nederland en de vierde in de wereld. Hij was niet alleen ooit verantwoordelijk voor een kwart van het wereldwijde web, ook vond hij nog tijd om de eerste homepage van Nederland te bouwen (en waarschijnlijk een van de eerste van de wereld). Een homepage was een persoonlijke pagina op het wereldwijde web. De site is nog altijd online te vinden(link is external) en is daarmee een van de oudste, nog online zijnde pagina’s op het wereldwijde web. Deze pagina, die in de huidige vorm uit 1994 dateert, is na bijna 26 jaar nog altijd onder constructie, zoals dat in het begin van de jaren negentig gebruikelijk was. Volgens de maker zelf heeft hij in de loop van de tijd alleen zijn mobiele telefoonnummer aan de site toegevoegd. De site is een echte “webincunabel” of “webwiegendruk”: het is een mooi voorbeeld van een born digital publicatie op het web die nog de typische kenmerken heeft van drukwerk op papier. In dit geval wordt het “papieren” uiterlijk nog versterkt door de virtuele ringband in 3D. De maker heeft wel gebruik gemaakt van een herkenbaar element dat alleen in een digitale publicaties mogelijk was: het bewegende mannetje met het schepje. Waarom is deze pagina nooit herkend als belangrijk digitaal erfgoed? Naar eigen zeggen was volgens de maker het feit dat de helft van het web Nederlands was op dat moment geen wereldnieuws. Het web was gewoon een stuk experimentele software die op de servers van Nikhef draaide. Pas nu in het digitale tijdperk, dertig jaar later, miljoenen sites en honderden miljarden links verder, kijken we vol bewondering naar de eerste Nederlandse digitale sporen op het web.

description: Semiconducting carbon nanotubes under high electric field stress (~10 V/um) display a striking, exponential current increase due to avalanche generation of free electrons and holes. Unlike in other materials, the avalanche process in such 1D quantum wires involves access to the third sub-band, is insensitive to temperature, but strongly dependent on diameter ~exp(-1/d^2). Comparison with a theoretical model yields a novel approach to obtain the inelastic optical phonon emission length, L_OP,ems ~ 15d nm. The combined results underscore the importance of multi-band transport in 1D molecular wires.

Effects of gravitational-wave recoil on the dynamics and growth of supermassive black holes

Publisher: name: arXiv
Year: 2008

subject: FOS: Physical sciences

description: Simulations of binary black hole mergers indicate that asymmetrical gravitational wave (GW) emission can cause black holes to recoil at speeds up to thousands of km/s. These GW recoil events can dramatically affect the coevolution of recoiling supermassive black holes (SMBHs) and their host galaxies. However, theoretical studies of SMBH-galaxy evolution almost always assume a stationary central black hole. In light of the numerical results on GW recoil velocities, we relax that assumption here and consider the consequences of recoil for SMBH evolution. We follow the trajectories of SMBHs ejected in a smooth background potential that includes both a stellar bulge and a multi-component gaseous disk. In addition, we calculate the accretion rate onto the SMBH as a function of time using a hybrid prescription of viscous (alpha-disk) and Bondi accretion. We find that recoil kicks between 100 km/s and the escape speed cause SMBHs to wander through the galaxy and halo for about 1 Myr - 1 Gyr before settling back to the galactic center. However, the mass accreted during this time is roughly constant at about 10% of the initial mass, independent of the recoil velocity. This indicates that while large recoils may disrupt active galactic nuclei feedback processes, recoil itself is an effective means of regulating SMBH growth. Recoiling SMBHs may be observable as spatially or kinematically offset quasars, but finding such systems could be challenging, because the largest offsets correspond to the shortest quasar lifetimes.

We develop the model for magnetoresistance of a thin ferromagnetic film in oblique magnetic field. The model accounts fairly well for our experimental findings, as well as for results of other researchers. We demonstrate that nonresonant microwave absorption is a powerful technique that allows contactless measurement of magnetic properties of thin films, including magnetoresistance, anisotropy field and coercive field.

description: The recent theoretical advance known as the Minimal Geometric Deformation (MGD) method has initiated a renewed interest in investigating higher curvature gravitational effects in relativistic astrophysics. In this work, we model a strange star within the context of Einstein-Gauss-Bonnet gravity with the help of the MGD technique. Starting off with the Tolman metric ansatz together with the MIT Bag model equation of state applicable to hadronic matter, anisotropy is introduced via the superposition of the seed source and the decoupled energy-momentum tensor. The solution of the governing systems of equations bifurcates into two distinct models, namely the mimicking of the $θ$ sector to the seed radial pressure and energy density and a regular fluid model. Each of these models can be interpreted as self-gravitating static, compact objects with the exterior described by the vacuum Boulware-Deser solution. Utilizing observational data for three stellar candidates, viz., PSR J1614-2230, PSR J1903+317, and LMC X-4 we subject our solutions to rigorous viability tests based on regularity and stability. We find that the Einstein-Gauss-Bonnet parameter and the decoupling constant compete against each other for ensuring physically realizable stellar structures. The novel feature of work is the demonstration of stable compact objects with stellar masses in excess of $M= 2 M_{\odot}$ without appealing to exotic matter. The analysis contributes new insights and physical consequences concerning the development of ultra-compact astrophysical entities.

description: We summarize recent results regarding single and double soft theorems of two different particles named dilatons, the Nambu-Goldstone boson of the spontaneously broken conformal field theories and the massless scalar particle of the closed string theories. Similarities and differences between the soft theorems of these two particles are discussed as well as their connections with the symmetries of the theories.

description: We show explicitly in two dimensional spacetime (d = 2) that the N = 2 Volkov-Akulov model is equivalent to the spontaneously broken linear supersymmetry (LSUSY) interacting gauge theory for N = 2 vector and N = 2 scalar supermultiplets. The local gauge interaction of LSUSY is induced by the specific composite structure of the auxiliary fields and the consequent transformations.

description: Although the theoretical understanding of the nonlinear gravitational clustering has greatly advanced in the last decades, in particular by the outstanding improvement on numerical N-body simulations, the physics behind this process is not fully elucidated. The main goal of this work is the study of the possibility of a turbulent-like physical process in the formation of structures, galaxies and clusters of galaxies, by the action of gravity alone. We use simulation data from the Virgo Consortium, in ten redshift snapshots (from 0 to 10). From this we identify galaxy-sized and cluster-sized dark matter haloes, by using a FoF algorithm and applying a boundedness criteria, and study the gravitational potential energy spectra. We find that the galaxy-sized haloes energy spectrum follows closely a Kolmogorov's power law, similar to the behaviour of dynamically turbulent processes in fluids. This means that the gravitational clustering of dark matter may admit a turbulent-like representation.

description: We present a distance measurement for the semiregular variable S Crateris (S Crt) based on its annual parallax. With the unique dual beam system of the VLBI Exploration for Radio Astrometry (VERA) telescopes, we measured the absolute proper motion of a water maser spot associated with S Crt, referred to the quasar J1147-0724 located at an angular separation of 1.23$^{\circ}$. In observations spanning nearly two years, we have detected the maser spot at the LSR velocity of 34.7 km s$^{-1}$, for which we measured the annual parallax of 2.33$\pm$0.13 mas corresponding to a distance of 430$^{+25}_{-23}$ pc. This measurement has an accuracy one order of magnitude better than the parallax measurements of HIPPARCOS. The angular distribution and three-dimensional velocity field of maser spots indicate a bipolar outflow with the flow axis along northeast-southwest direction. Using the distance and photospheric temperature, we estimate the stellar radius of S Crt and compare it with those of Mira variables.

description: By virtue of a silicon high-Q photonic crystal nanocavity, we propose and examine theoretically interactions between a stationary electron spin qubit of a semiconductor nanocrystal and a flying photon qubit. Firstly, we introduce, derive and demonstrate for the first time the explicit conditions towards realization of a spin-photon two-qubit phase gate, and propose these interactions as a generalized quantum interface for quantum information processing. Secondly, we examine novel single-spin-induced reflections as direct evidence of intrinsic bare and dressed modes in our coupled nanocrystal-cavity system. The excellent physical integration of this silicon system provides tremendous potential for large-scale quantum information processing.
Charged Black Holes in Phantom Cosmology

description: In the classical relativistic regime, the accretion of phantom-like dark energy onto a stationary black hole reduces the mass of black hole. Here we have investigated the accretion of phantom energy onto a stationary charged black hole and have determined the condition under which this accretion is possible. This condition restricts the mass to charge ratio in a narrow limit. This condition also challenges the validity of the cosmic censorship conjecture since a naked singularity is eventually produced as magnitude of charge increases compared to mass of black hole.

Identification of NeVIII lines in H-deficient (pre-) white dwarfs: a new tool to constrain the temperature of the hottest stars

description: For the first time, we have identified NeVIII absorption lines in far-UV spectra of the hottest known (Teff>150,000 K) hydrogen-deficient (pre-) white dwarfs of spectral type PG1159. They are of photospheric origin and can be matched by synthetic non-LTE line profiles. We also show that a number of UV and optical emission lines in these stars can be explained as being photospheric NeVIII features and not, as hitherto suspected, as ultrahigh ionised OVIII lines created along shock-zones in the stellar wind. Consequently, we argue that the long-standing identification of the same emission lines in hot [WR]-type central stars as being due to ultrahigh-ionised species (OVII-VIII, CV-VI) must be revised. These lines can be entirely attributed to thermally excited species (NeVII-VIII, NV, OVI). Photospheric NeVIII lines are also identified in the hottest known He-rich white dwarf KPD0005+5106 some of which were also attributed to OVIII previously. This is a surprise because it must be concluded that KPD0005+5106 is much hotter (Teff=200,000 K) than hitherto assumed (Teff=120,000 K). This is confirmed by a re-assessment of the HeII line spectrum. We speculate that the temperature is high enough to explain the mysterious, hard X-ray emission (1 keV) as being of photospheric origin.

A growth walk model for estimating the canonical partition function of Interacting Self Avoiding Walk

description: We have explained in detail why the canonical partition function of Interacting Self Avoiding Walk (ISAW), is exactly equivalent to the configurational average of the weights associated with growth walks, such as the Interacting Growth Walk (IGW), if the average is taken over the entire genealogical tree of the walk. In this context, we have shown that it is not always possible to factor the the density of states out of the canonical partition function if the local growth rule is temperature-dependent. We have presented Monte Carlo results for IGWs on a diamond lattice in order to demonstrate that the actual set of IGW configurations available for study is temperature-dependent even though the weighted averages lead to the expected thermodynamic behavior of Interacting Self Avoiding Walk (ISAW).
description: Revised version consisting of 12 pages (RevTeX manuscript, plus three .eps figure files); A few sentences in the second paragraph on Page 4 are rewritten so as to make the definition of the genealogical tree, ${\cal Z}_N$, clearer.

The Hold-up Problem in Colombian Contract Law
Creators: name: Gaviria, Juan Antonio
Publisher: name: American University
Year: 2023

description: As its title suggests, this dissertation studies the interaction between an economic issue (the hold-up problem) and a legal system (Colombian law). For this purpose, this dissertation first defines the hold-up problem and explains its causes and possible solutions. The dissertation then analyzes how U.S. and Colombian laws deal with the hold-up problem and with its main harmful effect: the reduction of idiosyncratic investments. The U.S. law is studied here not only to facilitate the comparison of a civil law country's approach to the hold-up problem (Colombia) with the perspective of a common law country (the United States) but also to inquire whether some of the solutions to the hold-up problem under the latter legal system might be successfully transplanted to the former one.The study of these legal systems delves into the role of both contractual and legal devices that may avoid, solve, or mitigate the hold-up problem (in general, that may prevent it). The contractual devices discussed here are no modification clauses, stipulated damages clauses, and reputation bonds. The legal devices, in turn, are legal rules entitling courts either to annul modifications in hold-up situations on grounds such as economic duress and bad-faith or to grant remedies for breach of contract.This theoretical analysis is coupled with an experiment with Colombian students testing the theories stating that penalty clauses (on one hand) and a high level of legal remedies for breach of contract (on the other) may prevent the hold-up problem. The results of this experiment failed to confirm the predictions of the theory. Based on the findings of the theoretical and experimental chapters, and before making some concluding remarks, the dissertation presents some proposals to efficiently address the hold-up problem in Colombian contract law.
