description: Let $X$ be a K3 surface with a polarization $H$ of the degree $H^2=2rs$, $r,s\ge 1$, and the isotropic Mukai vector $v=(r,H,s)$ is primitive. The moduli space of sheaves over $X$ with the isotropic Mukai vector $(r,H,s)$ is again a K3 surface, $Y$. In \cite{Nik2} the second author gave necessary and sufficient conditions in terms of Picard lattice $N(X)$ of $X$ when $Y$ is isomorphic to $X$ (some important particular cases were also considered in math.AG/0206158, math.AG/0304415 and math.AG/0307355). Here we show that these conditions imply existence of an isomorphism between $Y$ and $X$ which is a composition of some universal geometric isomorphisms between moduli of sheaves over $X$, and geometric Tyurin's isomorphsim between moduli of sheaves over $X$ and $X$ itself. It follows that for a general K3 surface $X$ with $ρ(X)=\text{rk\}N(X)\le 2$ and $Y\cong X$, there exists an isomorphism $Y\cong X$ which is a composition of the geometric universal and the Tyurin's isomorphisms. This generalizes our recent results math.AG/0605362 and math.AG/0606239 to a general case.

description: We consider 32 homotopy classifications of knot projections (images of generic immersions from a circle into a 2-sphere). These 32 equivalence relations are obtained based on which moves are forbidden among the five type of Reidemeister moves. We show that 32 cases contain 20 non-trivial cases that are mutually different. To complete the proof, we obtain new tools, i.e., new invariants.

description: In the modern economy, the relations between economic subjects are not limited to the contracts concluded in the middle or the vertical relations of the internal enterprise. State intervention in management, i.e. participation in coordinating economic activities based on the interests of the people, is called economic quasi-integration. Currently, a "cluster" is accepted as a type of quasi-integration in developed countries, which means a collection of enterprises performing various economic activities. Despite the fact that touristic clusters are theoretically similar structures with common and unique aspects, in practice, the question of their scientific classification remains open.

Key words: cluster, "Hub-and-spoke" clusters, production and national clusters, entrepreneurial structures.

description: In this work, we consider rule-based investment strategies for managing a defined contribution saving scheme under the Dutch pension fund testing model. We found that dynamic rule-based investment can outperform traditional static strategies, by which we mean that the pensioner can achieve the target retirement income with higher probability and limit the shortfall when target is not met. In comparison with the popular dynamic programming technique, the rule-based strategy has a more stable asset allocation throughout time and avoid excessive transactions, which may be hard to explain to the investor. We also study a combined strategy of rule based target and dynamic programming in this work. Another key feature of this work is that there is no risk-free asset under our setting, instead, a matching portfolio is introduced for the investor to avoid unnecessary risk.

description: We set up a strategy for studying large families of logarithmic conformal field theories by using the enlarged symmetries and non--semi-simple associative algebras appearing in their lattice regularizations (as discussed in a companion paper). Here we work out in detail two examples of theories derived as the continuum limit of XXZ spin-1/2 chains, which are related to spin chains with supersymmetry algebras gl($n|n$) and gl($n+1|n$), respectively, with open (or free) boundary conditions in all cases. These theories can also be viewed as vertex models, or as loop models. Their continuum limits are boundary conformal field theories (CFTs) with central charge $c=-2$ and $c=0$ respectively, and in the loop interpretation they describe dense polymers and the boundaries of critical percolation clusters, respectively. We also discuss the case of dilute (critical) polymers as another boundary CFT with $c=0$. Within the supersymmetric formulations, these boundary CFTs describe the fixed points of certain nonlinear sigma models that have a supercoset space as the target manifold, and of Landau-Ginzburg field theories. The submodule structures of indecomposable representations of the Virasoro algebra appearing in the boundary CFT, representing local fields, are derived from the lattice. A central result is the derivation of the fusion rules for these fields.
Staggered Baryon Operators with Flavor SU(3) Quantum Numbers

Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: The construction of the first baryon operators for staggered lattice QCD exploited the taste symmetry to emulate physical quark flavor; contemporary 2+1 flavor simulations explicitly include three physical quark flavors and necessitate interpreting a valence sector with twelve quarks. After discussing expected features of the resulting baryon spectrum, I consider the spectra of operators transforming irreducibly under SU(3)xGTS, the direct product of flavor SU(3) and the geometrical time-slice group of the 1-flavor staggered theory. I then describe the construction of a set of maximally local baryon operators transforming irreducibly under SU(3)xGTS and enumerate this set. In principle, the operators listed here could be used to extract the masses of all the lightest spin-1/2 and spin-3/2 baryon resonances of staggered QCD. Using appropriate operators from this set in partially quenched simulations should allow for particularly clean 2+1 flavor calculations of the masses of the nucleon and the lightest decuplet.

description: We study the polarization and dispersion properties of gluons moving within a weakly magnetized background at one-loop order. To this end, we show two alternative derivations of the charged fermion propagator in the weak field expansion and use this expression to compute the lowest order magnetic field correction to the gluon polarization tensor. We explicitly show that, in spite of its cumbersome appearance, the gluon polarization tensor is transverse as required by gauge invariance. We also show that none of the three polarization modes develops a magnetic mass and that gluons propagate along the light cone, non withstanding that Lorentz invariance is lost due to the presence of the magnetic field. By comparing with the expression for the gluon polarization tensor valid to all orders in the magnetic field, the existence of a second solution, corresponding to a finite gluon mass, is shown to be spurious and an artifact of the lowest order approximation in the field strength. We also study the strength of the polarization modes for real gluons. We conclude that, provided the spurious solutions are discarded, the lowest order approximation to the gluon polarization and dispersion properties is good as long as the field strength is small compared to the loop fermion mass.

description: Structural properties of CuAl$_{2}$O$_{4}$, which was recently argued to show unusual suppression of the Jahn-Teller distortions by the spin-orbit coupling, are investigated under pressures up to 6 GPa. Analysis of X-ray powder diffraction experiments shows that CuAl$_{2}$O$_{4}$ gets unstable and decomposes onto CuO and Al$_{2}$O$_{3}$ at pressures $\sim$ 6 GPa and temperature $\sim$ 1000 K. This finding is complemented by the DFT+U+SOC calculations, which demonstrate that this instability is partially driven by a (relatively) large compressibility of strongly Jahn-Teller distorted CuO.

Surface temperature and synthetic spectral energy distributions for rotationally deformed stars

description: The spectral energy distribution (SED) of a non-spherical star could differ significantly from the SED of a spherical star with the same average temperature and luminosity. Calculation of the SED of a deformed star is often approximated as a composite of several spectra, each produced by a plane parallel model of given effective temperature and gravity. The weighting of these spectra over the stellar surface, and hence the inferred effective temperature and luminosity, will be dependent on the inclination of the rotation axis of the star with respect to the observer, as well as the temperature and gravity distribution on the stellar surface. Here we calculate the surface conditions of rapidly rotating stars with a 2D stellar structure and evolution code and compare the effective temperature distribution to that predicted by von Zeipel's law. We calculate the composite spectrum for a deformed star by interpolating within a grid of intensity spectra of plane parallel model atmospheres and integrating over the surface of the star. Using this method, we find that the deduced variation of effective temperature with inclination can be as much as 3000 K for an early B star, depending on the details of the underlying model.

The role of the pufX protein in photosynthetic electron transfer
Creators: name: Lilburn, Timothy George
Publisher: name: University of British Columbia
Year: 2009

description: The role of the puJX gene product of Rhodobacter capsulatus has been unclear, but deletion of the gene renders the organism incapable of photosynthetic growth on a minimal medium. However, suppressor mutants that are able to grow photosynthetically are readily isolated. Two such suppressor mutants were characterized as to their photosynthetic growth properties, their fluorescence at five different incident light intensities, the integrity of their chromatophores and their abilities to generate a trans-membrane potential. I found that the photosynthetic apparatus in the suppressor mutants was less stable than that of the pseudo-wild type and primary mutant strain and that the suppressor mutants used light energy less efficiently than the pseudo-wild type strain. Therefore, the suppressor strains are more correctly designated partial suppressor mutants. The locations and sequences of the suppressor mutations were determined and both were found to change the second codon of the pufA gene. It is hypothesized that the serine residue encoded by this codon is important in interactions between the B870 antenna complex and other membrane-bound polypeptides. Based on these results and those of other investigators, a model for the role of the PufX protein is put forward in which the PufX protein, in conjunction with the B870 ft polypeptide, is proposed to form a gateway in the light harvesting antenna complex surrounding the reaction center. This gateway would allow the passage of quinones and quinols between the reaction center and the cytochrome blc\ complex.

For three- and four-body nuclei the nuclear Hamiltonian includes two- and three- nucleon forces, while semirealistic interactions are used in case of six- and seven-body systems. Comparisons with experimental data are discussed. In addition various interesting aspects of the $^4$He photodisintegration are studied: investigation of a tetrahedrical symmetry of $^4$He and a test of non-local nuclear force models via the induced two-body currents.

description: Oak Ridge National Laboratory (ORNL) experimental neutron science facilities produce 1.2\,TB a day of raw event-based data that is stored using the standard metadata-rich NeXus schema built on top of the HDF5 file format. Performance of several data reduction workflows is largely determined by the amount of time spent on the loading and processing algorithms in Mantid, an open-source data analysis framework used across several neutron sciences facilities around the world. The present work introduces new data management algorithms to address identified input output (I/O) bottlenecks on Mantid. First, we introduce an in-memory binary-tree metadata index that resemble NeXus data access patterns to provide a scalable search and extraction mechanism. Second, data encapsulation in Mantid algorithms is optimally redesigned to reduce the total compute and memory runtime footprint associated with metadata I/O reconstruction tasks. Results from this work show speed ups in wall-clock time on ORNL data reduction workflows, ranging from 11\% to 30\% depending on the complexity of the targeted instrument-specific data. Nevertheless, we highlight the need for more research to address reduction challenges as experimental data volumes increase.

description: We present here a new parametric resonance magnetometer scheme based on elliptically polarized pumping light and two radio-frequency fields applied along the two optical pumping directions. At optimum ellipticity and radio-frequency fields amplitudes the three components of the magnetic field are measured with an isotropic sensitivity. Compared to the usual alignment-based parametric resonance magnetometers, the sensitivity is degraded by a factor 2 for two components of the magnetic field but improved by a factor 11 for the third one. This new magnetometer configuration could be particularly interesting for geophysics and biomedical imaging.

description: In supervised learning, we often face with ambiguous (A) samples that are difficult to label even by domain experts. In this paper, we consider a binary classification problem in the presence of such A samples. This problem is substantially different from semi-supervised learning since unlabeled samples are not necessarily difficult samples. Also, it is different from 3-class classification with the positive (P), negative (N), and A classes since we do not want to classify test samples into the A class. Our proposed method extends binary classification with reject option, which trains a classifier and a rejector simultaneously using P and N samples based on the 0-1-$c$ loss with rejection cost $c$. More specifically, we propose to train a classifier and a rejector under the 0-1-$c$-$d$ loss using P, N, and A samples, where $d$ is the misclassification penalty for ambiguous samples. In our practical implementation, we use a convex upper bound of the 0-1-$c$-$d$ loss for computational tractability. Numerical experiments demonstrate that our method can successfully utilize the additional information brought by such A training data.

description: We have identified 41 infrared dark clouds from the 8 micron maps of the Midcourse Space Experiment (MSX), selected to be found within one square degree areas centered on known ultracompact HII regions. We have mapped these infrared dark clouds in N2H+(1-0), CS(2-1) and C18O(1-0) emission using the Five College Radio Astronomy Observatory. The maps of the different species often show striking differences in morphologies, indicating differences in evolutionary state and/or the presence of undetected, deeply embedded protostars. We derive an average mass for these clouds using N2H+ column densities of ~2500 solar masses, a value comparable to that found in previous studies of high mass star forming cores using other mass tracers. The linewidths of these clouds are typically ~2.0 - 2.9 km/s. Based on the fact that they are dark at 8 micron, compact, massive, and have large velocity dispersions, we suggest that these clouds may be the precursor sites of intermediate and high mass star formation.

description: We systematically investigate properties of various triangle centers (such as orthocenter or incenter) located on the four faces of a tetrahedron. For each of six types of tetrahedra, we examine over 100 centers located on the four faces of the tetrahedron. Using a computer, we determine when any of 16 conditions occur (such as the four centers being coplanar). A typical result is: The lines from each vertex of a circumscriptible tetrahedron to the Gergonne points of the opposite face are concurrent.

description: We revisit tensor algebras of subproduct systems with Hilbert space fibers, resolving some open questions in the case of infinite dimensional fibers. We characterize when a tensor algebra can be identified as the algebra of uniformly continuous noncommutative functions on a noncommutative homogeneous variety or, equivalently, when it is residually finite dimensional: this happens precisely when the closed homogeneous ideal associated to the subproduct system satisfies a Nullstellensatz with respect to the algebra of uniformly continuous noncommutative functions on the noncommutative closed unit ball. We show that - in contrast to the finite dimensional case - in the case of infinite dimensional fibers this Nullstellensatz may fail. Finally, we also resolve the isomorphism problem for tensor algebras of subproduct systems: two such tensor algebras are (isometrically) isomorphic if and only if their subproduct systems are isomorphic in an appropriate sense.

BARBARISM IN THE EYES OF LINGUISTS
Creators: name: Khatamova, Zulaykho
Publisher: name: Zenodo
Year: 2024

description: Inter-linguistic interactions are a natural phenomenon that occurs in the languages of each world and is characteristic of itself. During periods, certain words come into one language from other foreign languages under the influence of various factors. Such words are called barbarisms. Currently, there are several interpretations of the concept of" barbarism". Some linguists say the term is derived from the Greek word “barbarismos”, while others say it comes from the Latin word “barbaris”. In both cases, it means “foreign, alien".  Thus, in the dictionary of foreign words (I.V. Lyoxin and F.N. Edited by the Petrov) barbarism in a broad sense: "given as a word or phrase derived from another language and borrowed from another language" [7, p. 120].

description: This paper describes polarimetric strategies based on measuring the light's geometric phase, which results from the evolution of the polarisation state while traversing an optical system. The system in question is described by a homogeneous Jones matrix, which by definition, contains mutually perpendicular eigenpolarisations. Our leading theory links the system's Jones matrix parameters (eigenvalues and eigenvectors) with the input polarisation state and the geometric phase. We demonstrate two interferometric techniques. The first one measures the geometric phase based on the relative lateral fringe displacement between the interference pattern of two mutually-orthogonal polarisation states. The second technique uses the visibility of the interference fringes to determine the eigenpolarisations of the system. We present proof-of-principle experiments for both techniques.

Συγκεκριμένα, διερευνώνται τα χωροταξικά και κοινωνικά χαρακτηριστικά που προσδίδονται από τα δημοσιεύματα του τύπου στους χώρους χρήσης, οι στερεοτυπικές αναπαραστάσεις της χρήσης και των χρηστών και οι προτεινόμενες πολιτικές αντιμετώπισης του φαινομένου. Για την επίτευξη των στόχων της μελέτης αναλύθηκαν, με τη μέθοδο της ποιοτικής ανάλυσης περιεχομένου, 101 δημοσιεύματα που προέρχονται από 2 τοπικές και 2 πανελλήνιας κυκλοφορίας εφημερίδες και καλύπτουν την περίοδο 2000-2009. Η ανάλυση έδειξε ότι ο χωροταξικός διαχωρισμός της πόλης σε ασφαλείς και «επικίνδυνες» περιοχές, η διπλή στιγματοποίηση των χρηστών ως θυμάτων της εξάρτησης αλλά και ταυτόχρονα ως επικίνδυνης για τη δημόσια ασφάλεια κοινωνικής ομάδας και το εμφατικό αίτημα για κατασταλτική πολιτική και αύξηση της αστυνόμευσης αποτελούν συστατικά στοιχεία της κοινωνικής αναπαράστασης των χώρων χρήσης που διαμορφώνεται μέσα από το δημόσιο λόγο του τύπου.

More specifically it investigates the spatial and social characteristics attrributed by the press to drug use areas,the stereotypical representations of drug use and users and the policies proposed in order to address the problem of drug use. In order to meet the above objectives, 101 newspaper articles (from 2 local and 2 national newspapers) covering the period 2000-2009 were analysed by the use of qualitative content analysis. Analysis indicated that the spatial segregation of the city into safe and "dangerous" areas, the double stigmatization of drug users both as victims of addiction as well as a dangerous social group and the emphatic call for repression policies and increased monitoring are core constituents of the social representation of drug use areas constructed within the public discourse of the press. Moreover, the consideration of public drug use as an "urban phenomenon" is linked to discourses concerned with the (proper) use of public space and the management of 'risk' in modern cities.
Shifting meanings of Fazhi and China’s journey toward socialist rule of law

description: Scholars disagree over the nature, extent, and direction of the rule of law in China. Unlike researchers who see China’s rule of law situation as either static or steadily improving, this article traces the use, meaning, and implementation of fazhi (法治, literally “law governs,” usually translated as “rule of law”) at different stages in China since 1978. It argues that the real meaning of fazhi has changed over the past forty years. Correspondingly, China’s journey towards the socialist rule of law experienced some turns. China went from laying down a foundation for the rule of law in the late 1970s and 1980s, to turning to rule by law in the 1990s and 2000s, and then to using law to legitimize the rule of the Communist Party in the 2010s as the legal system became more mature and more sophisticated. This article further argues that, despite significant improvements in the legal system, socialist rule of law turns out to be the rule of man, with tightened legal institutions and sharpened legal tools, although it is also hoped that the key principles laid down in the 1980s and increased awareness of rights may bring about transformation in the future.

description: We propose a time-dependent approach to investigate the motion of electrons in quantum pump device configurations. The occupied one-particle states are propagated in real time and used to calculate the local electron density and current. An advantage of the present computational scheme is that the same computational effort is required to simulate monochromatic, polychromatic and nonperiodic drivings. Furthermore, initial state dependence and history effects are naturally accounted for. This approach can also be embedded in the framework of time-dependent density functional theory to include electron-electron interactions. In the special case of periodic drivings we combine the Floquet theory with nonequilibrium Green's functions and obtain a general expression for the pumped current in terms of inelastic transmission probabilities. This latter result is used for benchmarking our propagation scheme in the long-time limit. Finally, we discuss the limitations of Floquet-based schemes and suggest our approach as a possible way to go beyond them.

description: Η μετάνοια έχει θεμελιακή σημασία στη θεολογία του αγίου Νεοφύτου. Αποτελεί την αρχή της σωτηρίας του ανθρώπου και είναι αίσθηση, την οποία ο άνθρωπος καλείται να βιώνει συνεχώς μέχρι το τέλος της ζωής του. Η βίωση της μετάνοιας είναι πορεία που γνωρίζει διάφορα στάδια. Ο άγιος Νεόφυτος διακρίνει τα στάδια αυτά σε τρία: πρώτο είναι η αίσθηση της αγάπης του Θεού, δεύτερο η ανάσταση από την αμαρτία και η αμετάτρεπτος επιστροφή και τρίτο η εξομολόγηση και η συντριβή της καρδίας. Σε όποια κατάσταση κι αν βρεθεί ο άνθρωπος, όσο βαριά κι αν αμαρτήσει, η μετάνοια τίθεται πάντοτε ως δυνατότητα μπροστά του, αφού το έλεος και η αγάπη του Θεού υπερβαίνουν κάθε αμάρτημά του. Όλος ο χρόνος της ζωής του ανθρώπου είναι η ευκαιρία που του δίνεται από τον Θεό της αγάπης να μετανοήσει και να επιστρέψει κοντά του. Όταν ο άνθρωπος βιώσει τη μετάνοια αληθινά και γνήσια, τότε ζει το σταυρικό δρόμο που πρότεινε ο ίδιος ο Χριστός και έζησαν όλοι οι άγιοι της Εκκλησίας. Ο δρόμος αυτός με την κάθαρση των παθών και τον φωτισμό του νου οδηγεί στην επιφάνεια του Τριαδικού Θεού στον άνθρωπο, που σημαίνει την κατά χάριν θέωσή του. Αυτός είναι ο αληθινός σκοπός της όλης ζωής του ανθρώπου, όπως μας αποκαλύφθηκε στο πρόσωπο του Θεανθρώπου Χριστού, και αυτόν καλείται να ζήσει ο καθένας προσωπικά στη ζωή του. Ο Έγκλειστος της Πάφου, βιώνοντας την μετάνοια από τη σπηλιά όπου ζούσε, αγωνίστηκε να εμπνεύσει τη βίωσή της κατά πρώτο λόγο στους αδελφούς της μονής, και κατά δεύτερο σε όλους τους συντοπίτες του. Η ποιμαντική στη μετάνοια αποτέλεσε τον κεντρικό άξονα της διακονίας του αγίου Νεοφύτου ως ηγουμένου της Εγκλείστρας.
description: Repentance is fundamental in Saint Neophytos’s theology. It’s the beginning of people’s salvation and it’s also a feeling that those people are required to experience throughout their whole life. Experiencing repentance has different stages. Saint Neophytos supports that there are three stages: first, experiencing God’s love, second, resurrection from the sins and undoubtful return and third, sincere confession. Even if the people have severe sins, there is always the opportunity to repent since God’s love and mercy exceed any kind of sin. God is giving the people all the time in their life in order to repent and return closer to him. When the people repent genuinely, then they experience the crucified way that Jesus Christ suggested and all saints experienced. The way of cleansing of passions and enlightenment of the mind leads to the deification of human. This is the real goal of people’s life, as it was revealed in Jesus’s Christ life. While Saint Neophytos was experiencing repentance from the cave he used to live, he struggled to help the monks and the people who lived in the area of Paphos, to experience it in the same way. Pastoral of repentance was the main purpose of Saint Neophytos service as the superior of Encleistra’s monastery.

description: We compare eigenvalue densities of Wigner random matrices whose elements are independent identically distributed (iid) random numbers with a Levy distribution and maximally random matrices with a rotationally invariant measure exhibiting a power law spectrum given by stable laws of free random variables. We compute the eigenvalue density of Wigner-Levy (WL) matrices using (and correcting) the method by Bouchaud and Cizeau (BC), and of free random Levy (FRL) rotationally invariant matrices by adapting results of free probability calculus. We compare the two types of eigenvalue spectra. Both ensembles are spectrally stable with respect to the matrix addition. The discussed ensemble of FRL matrices is maximally random in the sense that it maximizes Shannon's entropy. We find a perfect agreement between the numerically sampled spectra and the analytical results already for matrices of dimension N=100. The numerical spectra show very weak dependence on the matrix size N as can be noticed by comparing spectra for N=400. After a pertinent rescaling spectra of Wigner-Levy matrices and of symmetric FRL matrices have the same tail behavior. As we discuss towards the end of the paper the correlations of large eigenvalues in the two ensembles are however different. We illustrate the relation between the two types of stability and show that the addition of many randomly rotated Wigner-Levy matrices leads by a matrix central limit theorem to FRL spectra, providing an explicit realization of the maximal randomness principle.

description: If P is a point inside triangle ABC, then the cevians through P extended to the circumcircle of triangle ABC create a figure containing a number of curvilinear triangles. Each curvilinear triangle is bounded by an arc of the circumcircle and two line segments lying along the sides or cevians of the original triangle. We give theorems about the relationships between the radii of circles inscribed in various sets of these curvilinear triangles.

description: Utilizing the ADM equations, we derive a metric and reduced field equations describing a general, spherically symmetric perfect fluid. The metric describes both the interior perfect fluid region and exterior vacuum Schwarzschild spacetime in a single coordinate patch. The exterior spacetime is in generalized Painleve-Gullstrand coordinates which is an infinite class of coordinate systems. In the static limit the system reduces to a Tolman-Oppenheimer-Volkoff equation on the interior with the exterior in Schwarzschild coordinates. We show the coordinate transformation for the non-static cases to comoving coordinates, where the metric is seen to be a direct generalization of the Lemaitre-Tolman-Bondi spacetime to include pressures.

description: We show that the {\em column sum optimization problem}, of finding a $(0,1)$-matrix with prescribed row sums which minimizes the sum of evaluations of given functions at its column sums, can be solved in polynomial time, either when all functions are the same or when all row sums are bounded by any constant. We conjecture that the more general {\em line sum optimization problem}, of finding a matrix minimizing the sum of given functions evaluated at its row sums and column sums, can also be solved in polynomial time.
