description: An odd number of gapless Dirac fermions is guaranteed to exist at a surface of a strong topological insulator. We show that in a thin-film geometry and under external bias, electron-hole pairs that reside in these surface states can condense to form a coherent exciton condensate, similar in general terms to the exciton condensate recently argued to exist in a biased graphene bilayer, but with different topological properties. Such a `topological' exciton condensate (TEC) exhibits a host of unusual properties; the most interesting among them is the fractional charge +-e/2 carried by a singly quantized vortex in the TEC order parameter.

description: (Abridged) Gas-phase complex organic molecules are commonly detected in the warm inner regions of protostellar envelopes. Recent models show that photochemistry in ices followed by desorption may explain the observed abundances. This study aims to experimentally quantify the broad-band UV-induced production rates of complex organics in CH3OH-rich ices at 20-70 K under ultra-high vacuum conditions. The reaction products are mainly identified by RAIRS and TPD experiments. Complex organics are readily formed in all experiments, both during irradiation and during a slow warm-up of the ices to 200 K after the UV lamp is turned off. The relative abundances of photoproducts depend on the UV fluence, the ice temperature, and whether pure CH3OH ice or CH3OH:CH4/CO ice mixtures are used. C2H6, CH3CHO, CH3CH2OH, CH3OCH3, HCOOCH3, HOCH2CHO and (CH2OH)2 are all detected in at least one experiment. The derived product-formation yields and their dependences on different experimental parameters, such as the initial ice composition, are used to estimate the CH3OH photodissociation branching ratios in ice and the relative diffusion barriers of the formed radicals. The experiments show that ice photochemistry in CH3OH ices is efficient enough to explain the observed abundances of complex organics around protostars and that ratios of complex molecules can be used to constrain their formation pathway.

description: We present a detailed study of the quantum dissipative dynamics of a charged particle in a magnetic field. Our focus of attention is the effect of dissipation on the low- and high-temperature behavior of the specific heat at constant volume. After providing a brief overview of two distinct approaches to the statistical mechanics of dissipative quantum systems, viz., the ensemble approach of Gibbs and the quantum Brownian motion approach due to Einstein, we present exact analyses of the specific heat. While the low-temperature expressions for the specific heat, based on the two approaches, are in conformity with power-law temperature-dependence, predicted by the third law of thermodynamics, and the high-temperature expressions are in agreement with the classical equipartition theorem, there are surprising differences between the dependencies of the specific heat on different parameters in the theory, when calculations are done from these two distinct methods. In particular, we find puzzling influences of boundary-confinement and the bath-induced spectral cutoff frequency. Further, when it comes to the issue of approach to equilibrium, based on the Einstein method, the way the asymptotic limit (time going to infinity) is taken, seems to assume significance.

Gluino NLSP, Dark Matter via Gluino Coannihilation, and LHC Signatures

description: The possibility that the gluino is the next to the lightest supersymmetric particle (NLSP) is discussed and it is shown that this situation arises in nonuniversal SUGRA models within a significant part of the parameter space compatible with all known experimental bounds. It is then shown that the gluino NLSP (GNLSP) models lead to a compressed sfermion spectrum with the sleptons often heavier than the squarks at least for the first two generations. The relic density here is governed by gluino coannihilation which is responsible for a relatively small mass splitting between the gluino and the neutralino masses. Thus the GNLSP class of models is very predictive first because the SUSY production cross sections at the LHC are dominated by gluino production and second because the gluino production itself proceeds dominantly through a single channel which allows for a direct determination of the gluino mass and an indirect determination of the neutralino mass due to a linear relation between these two masses which is highly constrained by coannihilation. A detailed analysis of these models shows that the jet production and tagged b-jets from the gluino production can be discriminated from the standard model background with appropriate cuts. It is found that the GNLSP models can be tested with just 10 fb$^{-1}$ of integrated luminosity and may therefore be checked with low luminosity runs in the first data at the LHC. Thus if a GNLSP model is realized, the LHC will turn into a gluino factory through a profuse production of gluinos with typically only a small fraction $\lesssim 5%$ of total SUSY events arising from other production modes over the allowed GNLSP model parameter space.

description: Since electronic and magnetic properties of many transition-metal oxides can be efficiently controlled by external factors such as the temperature, pressure, electric or magnetic field, they are regarded as promising materials for various applications. From the viewpoint of electronic structure, these phenomena are frequently related to the behavior of a small group of states close to the Fermi level. The basic idea of this project is to construct a low-energy model for the states near the Fermi level on the basis of first-principles density functional theory, and to study this model by modern many-body techniques. After a brief review of the method, the abilities of this approach will be illustrated on a number of examples, including multiferroic manganites and spin-orbital-lattice coupled phenomena in RVO3 (R being the three-valent element).

description: The basis of this book is composed on the monographs: 1. Kuznetsov D.F. Strong Approximation of Multiple Ito and Stratonovich Stochastic Integrals. Multiple Fourier series approach. St.-Petersburg Polytechnical University Press, St.-Petersburg. 2011. 282 p. (in English); 2. Dmitriy Kuznetsov. Approximation of Multiple Ito and Stratonovich Stochastic Integrals. Multiple Fourier series approach. AV Akademikerverlag, Saarbrucken. 2012, 300 p. (In English), which are the first monographs where the problem of strong (mean-square) approximation of multiple Ito and Stratonovich stochastic integrals is sistematically analyzed in the context of numerical integration of stochastic differential Ito equations. The presented book and mentioned monographs successfully use the tool of multiple and iterative Fourier series, built in the space L2 and pointwise, for the strong approximation of multiple stochastic integrals and open a new direction in researching of multiple Ito and Stratonovich stochastic integrals. We obtained a general result connected with expansion of multiple Ito stochastic integrals of any fixed multiplicity k, based on generalized multiple Fourier series converging in the space L2([t, T]x ... x [t,T]) (x .... x -- k-1 times). This result is adapted for multiple Stratonovich stochastic integrals of 1 -- 4 multiplicity for Legendre polynomial system and system of trigonometric functions, as well as for other types of multiple stochastic integrals. The theorem on expansion of multiple Stratonovich stochastic integrals with any fixed multiplicity k, based on generalized Fourier series converging pointwise is verified.
description: We obtained exact expressions for mean-square errors of approximation of multiple Ito stochastic integrals of 1 -- 4 multiplicity. We provided a significant practical material devoted to approximation of specific multiple Ito and Stratonovich stochastic integrals of 1 -- 5 multiplicity using the system of Legendre polynomials and the system of trigonometric functions. We compared the methods formulated in this book with existing methods. We consider some weak approximations of multiple Ito stochastic integrals. We proved the theorems about integration order replacement for multiple Ito stochastic integrals and for the multiple stochastic integrals according to martingale. We brought out two families of analytical formulas for calculation of stochastic integrals. This book will be interesting for specialists dealing with the theory of stochastic processes, applied and computational mathematics, senior students and postgraduates of technical institutes and universities, as well as for computer experts.

r-modes and mutual friction in rapidly rotating superfluid neutron stars

description: We develop a new perturbative framework for studying the r-modes of rotating superfluid neutron stars. Our analysis accounts for the centrifugal deformation of the star, and considers the two-fluid dynamics at linear order in the perturbed velocities. Our main focus is on a simple model system where the total density profile is that of an $n=1$ polytrope. We derive a partially analytic solution for the superfluid analogue of the classical r-mode. This solution is used to analyse the relevance of the vortex mediated mutual friction damping, confirming that this dissipation mechanism is unlikely to suppress the gravitational-wave driven instability in rapidly spinning superfluid neutron stars. Our calculation of the superfluid r-modes is significantly simpler than previous approaches, because it decouples the r-mode from all other inertial modes of the system. This leads to the results being clearer, but it also means that we cannot comment on the relevance of potential avoided crossings (and associated "resonances") that may occur for particular parameter values. Our analysis of the mutual friction damping differs from previous studies in two important ways. Firstly, we incorporate realistic pairing gaps which means that the regions of superfluidity in the star's core vary with temperature. Secondly, we allow the mutual friction parameters to take the whole range of permissible values rather than focussing on a particular mechanism. Thus, we consider not only the weak drag regime, but also the strong drag regime where the fluid dynamics is significantly different.

description: В статье раскрываются актуальные для культурных исследований проблемы городской идентичности личности и сообществ. Они решаются в аспекте принадлежности к городу как к определённому месту, манифестирующему собственную уникальность и ценности. Город является не только пространством, в котором человек работает и отдыхает – это место, где он общается, испытывает привязанность, хранит в памяти важные для него события. Город рассматривается не с позиции его функционирования как экономико-социального организма, а эксплицируется в качестве культурной системы, располагающей собственной исторической, мемориальной, культурной конфигурацией и содержанием.

description: We provide analytic proofs for the shape invariance of the recently discovered (Odake and Sasaki, Phys. Lett. B679 (2009) 414-417) two families of infinitely many exactly solvable one-dimensional quantum mechanical potentials. These potentials are obtained by deforming the well-known radial oscillator potential or the Darboux-Pöschl-Teller potential by a degree \ell (\ell=1,2,...) eigenpolynomial. The shape invariance conditions are attributed to new polynomial identities of degree 3\ell involving cubic products of the Laguerre or Jacobi polynomials. These identities are proved elementarily by combining simple identities.

A systematic study of the Dolly Varden, Salvelinus malma (Walbaum)
Creators: name: McPhail, John Donald
Publisher: name: University of British Columbia
Year: 2012

description: Sympatric populations of S. malma and S. alpinus from Alaska were compared using a discriminant function analysis. The comparison indicated little or no hybridization. S. malma is, therefore, regarded as a distinct species. S. malma has fewer gill rakers, pyloric caeca and pores along the lateral line than S. alpinus. Five hundred specimens of S. malma from 42 North American localities were examined. Considerable geographic variability was observed. The variation showed no correlation with latitude. Evidence is presented that subspecific distinctions are invalid in S. malma. It is suggested that S. malma evolved in the North Pacific area sometime during the Pliestocene.

Optimization search effort over the control landscapes for open quantum systems with Kraus-map evolution

description: A quantum control landscape is defined as the expectation value of a target observable $Θ$ as a function of the control variables. In this work control landscapes for open quantum systems governed by Kraus map evolution are analyzed. Kraus maps are used as the controls transforming an initial density matrix $ρ_{\rm i}$ into a final density matrix to maximize the expectation value of the observable $Θ$. The absence of suboptimal local maxima for the relevant control landscapes is numerically illustrated. The dependence of the optimization search effort is analyzed in terms of the dimension of the system $N$, the initial state $ρ_{\rm i}$, and the target observable $Θ$. It is found that if the number of nonzero eigenvalues in $ρ_{\rm i}$ remains constant, the search effort does not exhibit any significant dependence on $N$. If $ρ_{\rm i}$ has no zero eigenvalues, then the computational complexity and the required search effort rise with $N$. The dimension of the top manifold (i.e., the set of Kraus operators that maximizes the objective) is found to positively correlate with the optimization search efficiency. Under the assumption of full controllability, incoherent control modelled by Kraus maps is found to be more efficient in reaching the same value of the objective than coherent control modelled by unitary maps. Numerical simulations are also performed for control landscapes with linear constraints on the available Kraus maps, and suboptimal maxima are not revealed for these landscapes.

description: The local theory of the critical lines of 2D and 3D Gaussian fields that underline the cosmic structures is presented. In the context of cosmological matter distribution the subset of critical lines of the 3D density field serves to delineate the skeleton of the observed filamentary structure at large scales. A stiff approximation used to quantitatively describe the filamentary skeleton shows that the flux of the skeleton lines is related to the average Gaussian curvature of the 1D (2D) sections of the field, much in the same way as the density of the peaks. The distribution of the length of the critical lines with threshold is analyzed in detail, while the extended descriptors of the skeleton - its curvature and its singular points, are introduced and briefly described. Theoretical predictions are compared to measurements of the skeleton in realizations of Gaussian random fields in 2D and 3D. It is found that the stiff approximation predicts accurately the shape of the differential length, allows for analytical insight, and explicit closed form solutions. Finally, it provides a simple classification of the singular points of the critical lines: i) critical points; ii) bifurcation points; iii) slopping plateaux.

description: We calculate the contribution to the spin transfer torque from sequential tunneling through impurities in a magnetic tunnel junction. For a junction with weakly polarized ferromagnetic contacts, the torque is found to be in the plane spanned by the magnetizations of the ferromagnetic contacts and proportional to $\sin θ$, where $θ$ is the angle between the magnetic moments. If the polarization is larger, the torque acquires a significant out-of-plane component and a different dependence on $θ$.

Regulation of plasma calcium in man
Creators: name: McPherson, George Duncan
Publisher: name: University of British Columbia
Year: 2012

description: The kinetics of plasma calcium regulation in man were studied by noting the response to intravenous injection of calcium as gluconate given at the rate of 10 mg/kg/hr. Twenty-nine infusion tests were carried out on 20 adult male subjects. The series comprised normals, cases of hypoparathyroidism, hyperparathyroidism, Paget's Disease, and osteoporosis. All were hospitalized at the time of the study. The changes in levels of plasma calcium, phosphorus and citrate were followed by frequent blood sampling. Excretion of calcium, phosphorus and citrate by the kidney was also determined. In all cases, plasma calcium levels rose in response to the infusion and declined slowly after it had ended, returning to normal several hours later. Plasma phosphate and citrate also rose slightly, but more slowly than the plasma calcium, and remained elevated as long as plasma calcium was above normal. The increase in the calcium excretion rate was directly proportional to the plasma calcium during the period of hypercalcemia. From this linear relationship it was possible to estimate a tubular maximum (Tm) for reabsorption of calcium by the renal tubules. The value obtained for calcium Tm in this series of 8 normal subjects was 4.97 ± 0.27 mg/min (range 3.60 – 5.80). In the one case of osteoporosis studied, the Tm appeared to be increased following correction of a hyperchloremic acidosis. The increased calcium excretion during hypercalcemia is a most important homeostatic factor in restoring the plasma level to normal. The rapidity of the exchange between the bone and the soft tissue calcium compartments appeared to be much greater in the cases of Paget's disease, as might be predicted from the high rate of bone blood flow characteristic of this disease.

Fermi LAT Observation of Diffuse Gamma-Rays Produced Through Interactions between Local Interstellar Matter and High Energy Cosmic Rays

description: Observations by the Large Area Telescope (LAT) on the \textit{Fermi} mission of diffuse $γ$-rays in a mid-latitude region in the third quadrant (Galactic longitude $l$ from $200\arcdeg$ to $260\arcdeg$ and latitude $| b |$ from $22\arcdeg$ to $60\arcdeg$) are reported. The region contains no known large molecular cloud and most of the atomic hydrogen is within 1 kpc of the solar system. The contributions of $γ$-ray point sources and inverse Compton scattering are estimated and subtracted. The residual $γ$-ray intensity exhibits a linear correlation with the atomic gas column density in energy from 100 MeV to 10 GeV. The measured integrated $γ$-ray emissivity is $(1.63 \pm 0.05) \times 10^{-26} {\rm photons s^{-1} sr^{-1} H\mathchar`-atom^{-1}}$ and $(0.66 \pm 0.02) \times 10^{-26} {\rm photons s^{-1} sr^{-1} H\mathchar`-atom^{-1}}$ above 100 MeV and above 300 MeV, respectively, with additional systematic error of $\sim 10%$. The differential emissivity in 100 MeV--10 GeV agrees with calculations based on cosmic ray spectra consistent with those directly measured, at the 10% level. The results obtained indicate that cosmic ray nuclei spectra within 1 kpc from the solar system in regions studied are close to the local interstellar spectra inferred from direct measurements at the Earth within $\sim 10%$.

The pharynx measures up to 0.15 mm and shows pharyngeal tentacles forming an inverted cone towards the mouth. The male reproductive system consists of a pair of testes, a spherical seminal vesicle, and a C-shaped penis. The latter is constituted by a sclerotized tube, about 50 µm long, with a broad basis, gradually narrowing towards the tip (Fig. 11 B). The female reproductive system shows a “bursa seminalis” located between the ovaries, and the uterus with an intestinal connection. The uterus contained 2 egg capsules, each with 2 eggs (Fig. 11 A). Specimens examined. MZU 00206: coll. J. A. L. Braccini and F. Brusa, 26 March 2012, Brazil, Rio Grande do Sul, Tramandaí (30°05ʹ09ʺ S, 050°10ʹ24ʺ W). Remarks on ecology and distribution. This species had moderate abundance in the winter/spring survey but was absent in the summer/autumn survey (Table 2). Baicalellia evelinae was previously reported from 3 localities in the state of São Paulo (Marcus 1946). The current record represents a southeastern range extension of about 800 km.

Subjects: Zenon, Egypt, ancient history, Digital Humanities, Social Network Analysis

description: Presentation of the talk "Exploring Ancient History through Social Network Analysis of the Zenon Archive", held at the University of Rostock on May, 23, 2023 in the lecture series "Digital Humanities im Fokus: Methoden, Anwendungen und Perspektiven". Abstract: The Zenon archive is the most extensive surviving collection of documents dating back to the Ptolemaic period (305-30 BCE), comprising over 1800 texts. It serves as a valuable source for gaining insight into the social dynamics of ancient Egypt. Specifically, this presentation explores Social Network Analysis (SNA) as a viable approach to analyzing and examining the archive's large quantities of historical textual evidence. The texts in question are written on papyri and focus on the daily dealings and administration of a rural estate in the Fayum, spanning between 263 and 229 BCE. In this presentation, we will explore how computational methods can help historians overcome the challenges of working on large and complex datasets by leveraging existing digital resources and methodologies in papyrology and digital humanities. Additionally, we will discuss the basics of SNA and its practical applications within the context of the Zenon archive. Bio: Fernanda Alvares Freire is a research associate at the University of Rostock, working with Jun.-Prof. Ulrike Henny-Krahmer in the field of Digital Humanities. After her bachelor's and master's degrees in history at the University of Brasilia, she started her PhD studies in Ancient History at the University of Münster. Her research investigates the social relations within the texts of the Zenon Archive from the 3rd century BC, focusing on everyday businesses and social interactions. As a historian specializing in Ancient History, she is particularly interested in Digital Humanities, and her research combines historical approaches with the application of digital methods, such as social network analysis, data mining, and data management.
