Extreme-value copulas associated with the expected scaled maximum of independent random variables
Creators: name: Mai, Jan-Frederik
Publisher: name: arXiv
Year: 2018
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: It is well-known that the expected scaled maximum of non-negative random variables with unit mean defines a stable tail dependence function associated with some extreme-value copula. In the special case when these random variables are independent and identically distributed, min-stable multivariate exponential random vectors with the associated survival extreme-value copulas are shown to arise as finite-dimensional margins of an infinite exchangeable sequence in the sense of De Finetti's Theorem. The associated latent factor is a stochastic process which is strongly infinitely divisible with respect to time, which induces a bijection from the set of distribution functions F of non-negative random variables with finite mean to the set of Lévy measures on the positive half-axis. Since the Gumbel and the Galambos copula are the most popular examples of this construction, the investigation of this bijection contributes to a further understanding of their well-known analytical similarities. Furthermore, a simulation algorithm based on the latent factor representation is developed, if the support of F is bounded. Especially in large dimensions, this algorithm is efficient because it makes use of the De Finetti structure.

description: We have used the analogy between gravitational systems and non-homogeneous fluid flows to calculate the density-density correlation function of an atomic Bose-Einstein condensate in the presence of an acoustic black hole. The emission of correlated pairs of phonons by Hawking-like process results into a peculiar long-range density correlation. Quantitative estimations of the effect are provided for realistic experimental configurations.

description: An expedient, eco-friendly and efficient procedure for the synthesis of novel 2-amino-3-nitro-4H-chromene derivatives has been developed through the reaction of various 2-hydroxybenzaldehydes and (E)-N-methyl-1-(methylthio)-2-nitroethenamine in the presence of the basic ionic liquid catalyst (choline hydroxide (ChOH)) at room temperature an aqueous medium. The advantageous of this method is a biodegradable and recyclable catalyst, mild, environmentally friendly and high products yields (83-96%) in short reaction times.
Microlensing by Stars in the Disk of M31
Creators: name: Gould, Andrew
Publisher: name: arXiv
Year: 1994
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The optical depth to microlensing toward M31 due to known stars in the disk of M31 itself is $τ\sim 2\times 10^{-7}e^{-r/d}$ where $d$ is the disk scale length and $r$ is the distance along the major axis. Thus, there can be significant lensing toward the M31 disk even if M31 contains no dark compact objects. The optical depth has a strong dependence on azimuthal angle: at fixed radius $τ\propto[1+ (h/d)\tan i\cosϕ]^{-2}$ where $h$ is the scale height of the disk, $i=75^\circ$ is the inclination of M31, and $ϕ$ is the azimuthal angle relative to the near minor axis. By measuring the optical depth as a function of radial and azimuthal position, it is possible to estimate $h$ and $d$ for the mass of the M31 disk, and so determine whether the disk light traces disk mass. Ground-based observations in $0.\hskip-2pt''5$ seeing of 0.8 $\rm deg^2$ once per week could yield $\sim 3$ events per year. With an ambitious space-based project, it would be possible to to observe $\sim 80$ events per year. If lensing events were dominated by the M31 spheroid rather than the disk, the event rate would be higher and the spheroid's parameters could be measured. The pattern of optical depths differs substantially for a disk and a spheroid.

title: The metabolism of the branched-chain amino acids in the rat
Creators: name: Sketcher, RD
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 1976

description: This thesis is primarily concerned with the adaptation of leucine oxidation in rats that are either fasting or have been fed protein restricted diets. It also includes the adaptation of valine oxidation in rats fed a protein-free diet for periods of up to 3 weeks. The initial experiments were concerned with resolving the differences of opinion which held in contention the ability of the malnourished rat to adapt to a low-protein diet and in particular to conserve the branched-chain amino acids. Much of the disagreement was later found to be due to the choice of the radio-active label for measurement of output following a tracer dose of the labelled for measurement of I4/CO2 output following a tracer dose of the labelled branched-chain amino acid (B.C.A). Parallel studies on the first two enzymes concerned with the catabolism of the B.C.As were also carried out in liver and gastrocnemius muscle to understand better the control mechanism and chief site of oxidation. The preliminary studies demonstrated dehydrogenase activity in skeletal muscle a a well as in liver. It was the first demonstration of this enzyme activity in rat skeletal muscle. Moreover, the degree of enzyme adaptation led to the hypothesis that skeletal muscle was the chief site of both oxidation and its control. Further studies were carried out to observe the effects of feeding a protein-free diet to rats of varying ages for periods of 1, 2 or 3 weeks. Enzyme activities and oxidation were measured. This gave further support to the original hypothesis. Subsequently a more accurate measure of skeletal leucine oxidation was developed. By using the method of a constant tall rein infusion of a radioactive tracer in vivo it was possible to estimate accurately the total body flux of leucine, together with total body protein turnover and rates of leucine oxidation. Similarly, by giving a constant infusion of the same radioactive tracer to the perfused hind-limb of an identically treated rat, it was possible to arrive at a more accurate measure of the contribution of skeletal muscle to total body leucine oxidation.

description: In 1973 two Salam protégés (Derek Capper and the author) discovered that the conformal invariance under Weyl rescalings of the metric tensor $g_{μν}(x)\rightarrowΩ^2(x)g_{μν}(x)$ displayed by classical massless field systems in interaction with gravity no longer survives in the quantum theory. Since then these Weyl anomalies have found a variety of applications in black hole physics, cosmology, string theory and statistical mechanics. We give a nostalgic review.

description: Ultra-small superparamagnetic iron oxide nanoparticles (USPIO-NPs) are widely used as clinical magnetic resonance imaging contrast agents for hepatic diseases diagnosis. USPIO-NPs often damage the hepatocytes and affect the function of liver but its mechanism of action remains unclear. In the present study, USPIO-NPs caused higher cytotoxicity and lactate dehydrogenase (LDH) leakage in hepatic L02 cells than SPIO-NPs. Subsequently, USPIO-NPs affected more genes’ expression than SPIO-NPs analyzed through microarray and bioinformatics analysis. The affected genes were involved in several biological processes, including calcium ion homeostasis, inflammatory response-related leukocyte chemotaxis, and migration. In addition, the level of endoplasmic reticulum (ER) calcium ion was increased by USPIO-NPs. USPIO-NPs also upregulated the genes related to acute-phase inflammation, including IL1B, IL6, IL18, TNFSF12, TNFRSF12, SAA1, SAA2, JAK1, STAT5B, and CXCL14. Furthermore, interleukin-6 (IL-6) secretion was elevated by USPIO-NPs as detected using ELISA. On the other hand, USPIO-NPs changed the morphology of ER and triggered the ER stress and unfolded protein response PERK/ATF4 pathway. Furthermore, blocking ER stress with inhibitor or ATF4 small interfering RNA counteracted IL-6-related acute-phase inflammation and cytotoxicity caused by USPIO-NPs. Taken together, we found that the USPIO-NPs could trigger stronger IL-6-related acute-phase inflammation than SPIO-NPs in hepatocytes. We demonstrated, for the first time, that IL-6-related acute-phase inflammation caused by NPs was regulated by PERK/ATF4 signaling. The PERK/ATF4 pathway explored in this study could be a candidate for diagnostic and therapeutic target against NPs-induced liver injury and cytotoxicity, which would be helpful for USPIO-NPs medical application.
Consideration of the relationship between Kepler and cyclotron dynamics leading to prediction of a non-MHD gravity-driven Hamiltonian dynamo

description: Conservation of canonical angular momentum shows that charged particles are typically constrained to stay within a poloidal Larmor radius of a poloidal magnetic flux surface. However, more detailed consideration shows that particles with a critical charge to mass ratio can have zero canonical angular momentum and so be both immune from centrifugal force and not constrained to stay in the vicinity of a specific flux surface. Suitably charged dust grains can have zero canonical angular momentum and in the presence of a gravitational field will spiral inwards across poloidal magnetic surfaces toward the central object and accumulate. This accumulation results in a gravitationally-driven dynamo, i.e., a mechanism for converting gravitational potential energy into a battery-like electric power source.

description: Network dismantling is to identify a minimal set of nodes whose removal breaks the network into small components of subextensive size. Because finding the optimal set of nodes is an NP-hard problem, several heuristic algorithms have been developed as alternative methods, for instance, the so-called belief propagation-based decimation (BPD) algorithm and the collective influence (CI) algorithm. Here, we test the performance of each of these algorithms and analyze them in the perspective of the fractality of the network. Networks are classified into two types: fractal and non-fractal networks. Real-world examples include the World Wide Web and Internet at the autonomous system level, respectively. They have different ratios of long-range shortcuts to short-range ones. We find that the BPD algorithm works more efficiently for fractal networks than for non-fractal networks, whereas the opposite is true of the CI algorithm. Furthermore, we construct diverse fractal and non-fractal model networks by controlling parameters such as the degree exponent, shortcut number, and system size, and investigate how the performance of the two algorithms depends on structural features.

Publisher: name: London School of Hygiene & Tropical Medicine
Year: 1973

description: The system of health care known as the Under Fives Clinic has been in existence in some African countries for the past ten years. The present study endeavours to evaluate this system of health care. An epidemiological study was undertaken in four areas of Africa each with an established Under Fives Clinic. These areas were Ilesha and Esa Oke in Western Nigeria, Namitambo in the Southern Province of Malawi and Mansa in the Luapula Province of Zambia. The method used was a point prevalence study that involved a stratified sample of approximately 200 dwellings in which lived children under the age of five years, for each area. In Ilesha there were 434 children, in Esa Oke 405, in Namitambo 261, and in Mansa 314 children who were taken into the survey. Data were collected from the families of these children using a questionnaire administered by an interviewer, that sought information on family and domestic circumstances and the health of the child. From this approach children who attended the clinic and those who did not were identified. A comparison between clinic attenders and non attenders has been made to discover whether there are any differences in the health of the two groups; and also what factors might influence health in these two groups. In general there were no major differences in health. Differences were found between the Under Fives Clinics in their activities, and this was reflected for example in the immunisation status of the children attending. The present study was the first of its kind to undertake a comparative evaluation of Under Fives Clinics in Africa. The methodology used in this study, with some modifications could be used in further evaluation studies where instead of doctors, medical auxiliaries, lay workers and even secondary school children could, perform the field work.

description: The radiative decays of heavy mesons and heavy baryons are studied in a formalism which incorporates both the heavy quark symmetry and the chiral symmetry. The chiral Lagrangians for the electromagnetic interactions of heavy hadrons consist of two pieces: one from gauging electromagnetically the strong-interaction chiral Lagrangian, and the other from the anomalous magnetic moment interactions of the heavy baryons and mesons. Due to the heavy quark spin symmetry, the latter contains only one independent coupling constant in the meson sector and two in the baryon sector. These coupling constants only depend on the light quarks and can be calculated in the nonrelativistic quark model. However, the charm quark is not heavy enough and the contribution from its magnetic moment must be included. Applications to the radiative decays $D^\ast \rightarrow D γ~,~B^\ast \rightarrow B γ~,~ Ξ^\prime_c \rightarrow Ξ_c γ~, Σ_c \rightarrow Λ_c γ$ and $Σ_c \rightarrow Λ_c πγ$ are given. Together with our previous results on the strong decay rates of $D^\ast \rightarrow D π$ and $Σ_c \rightarrow Λ_c π$, predictions are obtained for the total widths and branching ratios of $D^\ast$ and $Σ_c$. The decays $Σ^+_c \rightarrow Λ^+_c π^0 γ$ and $Σ^0_c \rightarrow Λ^+_c π^- γ$ are discussed to illustrate the important roles played by both the heavy quark symmetry and the chiral symmetry.

description: We examine a 200 ks XMM-Newton observation of the narrow-line Seyfert 1 galaxy Mrk 493. The active galaxy was half as bright as in a previous 2003 snapshot observation and the current lower flux enables a study of the putative reflection component in detail. We determine the characteristics of the 2015 X-ray continuum by first analyzing the short-term variability using model-independent techniques. We then continue with a time-resolve analysis including spectral fitting and modelling the fractional variability. We determine that the variability arises from changes in the amount of primary flux striking the accretion disk, which induces changes in the ionization parameter and flux of the blurred reflection component. The observations seem consistent with the picture that the primary source is of roughly constant brightness and that variations arise from changes in the degree of light bending happening in the vicinity of the supermassive black hole.

title: Physiological Responses to Exercise Following Disuse Muscular Atrophy in Man
Creators: name: Sargeant, AJ
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 1976

description: Measurements were made of the physiological responses to exercise in patients who had had one leg immobilised following bone fracture. As a consequence of immobilisation they had muscular weakness and atrophy of the affected limb. Data were also collected for comparative purposes on normal healthy male subjects. Exercise was performed pedalling a stationary bicycle ergometer with each leg separately and both legs together and a system was developed to enable the pattern or force exerted on the crank by each leg to be measured. Anthropometric data including estimates of total leg and component tissue volumes were also obtained. Analysis of the pattern of force exerted in cycling established the comparability of 1-leg exercise involving patients' injured or uninjured legs. In 2-leg cycling the patients showed a disproportionate sharing of work between the legs, although the actual 'pattern* of force remained the same in both legs and the same as in 1-leg cycling. In submaximal exercise with the patients’ injured leg the oxygen uptake (iO2) for a given work load and cardiac frequency for a given iO2 were higher than with the uninjured leg. Rated perceived exertion was also higher for a given iO2 during exercise with the patients' Injured leg, but this difference was removed when iO2 was expressed in relative terms (% iO2 max). Maximum oxygen uptake (iO2 max) was reduced by -11% in the injured (cf. uninjured) leg, and was associated with the degree of muscle atrophy estimated anthropometrically. In 2-leg exercise there was a greater reduction of i02 max for a given leg muscle (plus bone) volume when comparison was made with normal subjects. The effect of rehabilitation therapy undertaken by the patients was to restore 1— and 2—leg exercises toward normal. The patient data were interpreted in relation to normal data including consideration of the effect of habitual limb preference.

description: Purpose: To characterize and monitor the clinical and electrophysiological features of a Chinese patient with KCNV2 retinopathy. Methods: A 17-year-old Chinese male with the diagnosis of cone dystrophy with supernormal rod response (CDSRR) was followed-up for 5 years, with full ophthalmological examinations, including decimal best corrected visual acuity (BCVA), fundus photography, fundus autofluorescence (FAF) imaging, spectral-domain optical coherence tomography (SD-OCT), and full-field electroretinogram (ERG). Genetic screening was performed to detect the sequence variations in the retinal dystrophy associated genes in the patient and his parents. Results: The patient demonstrated the characteristic full-field electroretinography (ERG) features of CDSRR, namely a profound enlargement of the dark-adapted ERG b-wave amplitude with increasing flash strength and a broadened a-wave trough; this case also had undetectable light-adapted ERGs. A BCVA of 0.15 was maintained over 5 years in both eyes; while progressive macular atrophy was identified. Molecular genetic analyses revealed two novel disease-causing KCNV2 variants in compound heterozygous state: c.1408 G > C (p.Gly470Arg) and c.1500 C > G (p.Tyr500Ter). Conclusions: This is the first long-term case study of an East Asian patient with molecularly confirmed CDSRR. The progressive atrophy with maintained VA demonstrated in this case will be valuable for increasing the understanding of the natural course of KCNV2 retinopathy and it will help in counselling patients with this disease.

description: Many angiosperms have undergone some series of polyploidization events over the course of their evolutionary history. In these genomes, especially those resulting from multiple autopolyploidization, it may be relatively easy to recognize all the sets of n homeologous chromosomes, but it is much harder, if not impossible, to partition these chromosomes into n subgenomes, each representing one distinct genomic component of chromosomes making up the original polyploid. Thus, if we wish to infer the polyploidization history of the genome, we could make use of all the gene trees inferred from the genes in one set of homeologous chromosomes to construct a consensus tree, but there is no evident way of combining the trees from the different sets because we have no labelling of the chromosomes that is known to be consistent across these sets. We suggest here that lacking a consistent leaf-labelling, the topological structure of the trees may display sufficient resemblance so that a higher level consensus could be revealing of evolutionary history. This would be especially true of the peripheral structures of the tree, likely representing events that occurred more recently and have thus been less obscured by subsequent evolutionary processes. Here, we present a statistical test to assess whether the subgenomes in a polyploid genome could have been added one at a time. The null hypothesis is that the accumulation of chromosomes follows a stochastic process in which transition from one generation to the next is through randomly choosing an edge, and then subdividing this edge in order to link the new internal vertex to a new external vertex. We analyze the probability distributions of a number of peripheral tree substructures, namely leaf- or terminal-pairs, triples and quadruples, arising from this stochastic process, in terms of some exact recurrences. We propose some conjectures regarding the asymptotic behaviours of these distributions. Applying our analysis to a sugarcane genome, we demonstrate that it is unlikely that the accumulation of subgenomes has occurred one at a time in this genome.

We find that the equations, corresponding to the perturbation of the integrals of motion, i.e; Bernoulli's constant and the mass flow rate, satisfy massless scalar field equation in a time dependent acoustic metric. When one is interested up to the second order behaviour of the perturbations, the emergent time dependent acoustic metric of the system, derived from the massless scalar field equations of the perturbations of the integrals of motion, has some astounding similarities with the metric describing gravitational wave in Minkowski spacetime.

description: We consider solutions to low energy string theory which have a horizon and a spacelike symmetry. Each of these solutions has a geometrically different dual description. We show that the dual solution has a horizon with exactly the same Hawking temperature (surface gravity) and entropy (area) as the original solution.

Autoxidation

description: Plasmalogens have been reported to possess antioxidant activity; a paradoxical finding given that plasmalogens often comprise highly oxidizable polyunsaturated fatty acids esterified to the central position of the glycerol backbone. However a reasonable mechanism accounting for plasmenyl lipid activity has yet to be advanced, despite the fact that other monounsaturated lipids including cholesterol and oleate have been extensively studied. Plasmenylcholine was synthesized de novo to resolve its antioxidant activity as well as to carry out mechanistic studies to understand its basis. Autoxidation of a vinyl ether model substrate yielded a kp of 6 M-1 s-1, which affirmed it was as slower than cholesterol. However, corresponding experiments with a deuterated substrate yielded a value of 89 M-1 s-1, questioning the reliability of these studies. Our studies of plasmenyl lipid peroxidation inspired us to look into the mechanism of autoxidation of the monounsaturated lipid, oleate (using LC-MS/MS with APCI+), which was reported to proceed exclusively via H-atom transfer (HAT). Herein we have shown for the first time that oleate epoxides are formed in the autoxidation of the monounsaturated lipid.

description: Thanks to their highly tunable band gaps, graphene nanoribbons (GNRs) with atomically precise edges are emerging as mechanically and chemically robust candidates for nanoscale light emitting devices of modulable emission color. While their optical properties have been addressed theoretically in depth, only few experimental studies exist, limited to ensemble measurements and without any attempt to integrate them in an electronic-like circuit. Here we report on the electroluminescence of individual GNRs suspended between the tip of a scanning tunneling microscope (STM) and a Au(111) substrate, constituting thus a realistic opto-electronic circuit. Emission spectra of such GNR junctions reveal a bright and narrow band emission of red light, whose energy can be tuned with the bias voltage applied to the junction, but always lying below the gap of infinite GNRs. Comparison with {\it ab initio} calculations indicate that the emission involves electronic states localized at the GNR termini. Our results shed light on unpredicted optical transitions in GNRs and provide a promising route for the realization of bright, robust and controllable graphene-based light emitting devices.

description: Twin entangled beams produced by single-pass parametric down-conversion (PDC) offer the opportunity to detect weak amount of absorption with an improved sensitivity with respect to standard techniques which make use of classical light sources. We propose a differential measurement scheme which exploits the spatial quantum correlation of type II PDC to image a weak amplitude object with a sensitivity beyond the standard quantum limit imposed by shot-noise.

Statistics of N-Body Simulations. II. Equal Masses after Core Collapse

description: This paper presents and analyses statistical results from a large number of $N$-body simulations of isolated systems with equal masses, in which $250\le N\le 2000$. It concentrates on the phase starting around the end of core collapse, when binaries start to play a crucial role. Interactions of hard binaries are consistent with the Spitzer (1987) cross section. The evolution of the half-mass radius after core collapse nearly follows classical theory, The evolution of the inner parts of the system around the time of core bounce is consistent with these simplified models provided that the continuous production of energy, as usually assumed, is replaced by a model of {\sl stochastic} energy production. Similarly, post-collapse evolution of the core requires a modest recalibration of the coefficient of energy generation, especially for small $N$. The distributions of velocity dispersion and anisotropy become remarkably homologous soon after core bounce. The bound mass of the systems very nearly follows a power law with time. A small number of escapers, presumed to be those associated with binary activity, dominate the energy which is carried off. The ``internal" energy of escaping binaries is consistent with theoretical expectations.

description: In this paper we review basic properties of coupled periodic and aperiodic nanopillar waveguides. A coupled nanopillar waveguide consists of several rows of periodically or aperiodically placed dielectric rods (pillars). In such a waveguide, light confinement is due to the total internal reflection, while guided modes dispersion is strongly affected by the waveguide structure. We present a systematic analysis of the optical properties of coupled nanopillar waveguides and discuss their possible applications for integrated optics.

Revealing the Micro-Structure of the Giant Component in Random Graph Ensembles

description: The micro-structure of the giant component of the Erd{\H o}s-Rényi network and other configuration model networks is analyzed using generating function methods. While configuration model networks are uncorrelated, the giant component exhibits a degree distribution which is different from the overall degree distribution of the network and includes degree-degree correlations of all orders. We present exact analytical results for the degree distributions as well as higher order degree-degree correlations on the giant components of configuration model networks. We show that the degree-degree correlations are essential for the integrity of the giant component, in the sense that the degree distribution alone cannot guarantee that it will consist of a single connected component. To demonstrate the importance and broad applicability of these results, we apply them to the study of the distribution of shortest path lengths on the giant component, percolation on the giant component and the spectra of sparse matrices defined on the giant component. We show that by using the degree distribution on the giant component, one obtains high quality results for these properties, which can be further improved by taking the degree-degree correlations into account. This suggests that many existing methods, currently used for the analysis of the whole network, can be adapted in a straightforward fashion to yield results conditioned on the giant component.

description: Canonical correlation analysis (CCA) is a powerful technique for discovering whether or not hidden sources are commonly present in two (or more) datasets. Its well-appreciated merits include dimensionality reduction, clustering, classification, feature selection, and data fusion. The standard CCA however, does not exploit the geometry of the common sources, which may be available from the given data or can be deduced from (cross-) correlations. In this paper, this extra information provided by the common sources generating the data is encoded in a graph, and is invoked as a graph regularizer. This leads to a novel graph-regularized CCA approach, that is termed graph (g) CCA. The novel gCCA accounts for the graph-induced knowledge of common sources, while minimizing the distance between the wanted canonical variables. Tailored for diverse practical settings where the number of data is smaller than the data vector dimensions, the dual formulation of gCCA is also developed. One such setting includes kernels that are incorporated to account for nonlinear data dependencies. The resultant graph-kernel (gk) CCA is also obtained in closed form. Finally, corroborating image classification tests over several real datasets are presented to showcase the merits of the novel linear, dual, and kernel approaches relative to competing alternatives.

description: OBJECTIVE: The TER system is a robot-based tele-echography system allowing remote ultrasound examination. The specialist moves a mock-up of the ultrasound probe at the master site, and the robot reproduces the movements of the real probe, which sends back ultrasound images and force feedback. This tool could be used to perform ultrasound examinations in small health care centers or from isolated sites. The objective of this study was to prove, under real conditions, the feasibility and reliability of the TER system in detecting abdominal aortic and iliac aneurysms. METHODS: Fifty-eight patients were included in 2 centers in Brest and Grenoble, France. The remote examination was compared with the reference standard, the bedside examination, for aorta and iliac artery diameter measurement, detection and description of aneurysms, detection of atheromatosis, the duration of the examination, and acceptability. RESULTS: All aneurysms (8) were detected by both techniques as intramural thrombosis and extension to the iliac arteries. The interobserver correlation coefficient was 0.982 (P < .0001) for aortic diameters. The rate of concordance between 2 operators in evaluating atheromatosis was 84% +/- 11% (95% confidence interval). CONCLUSIONS: Our study on 58 patients suggests that the TER system could be a reliable, acceptable, and effective robot-based system for performing remote abdominal aortic ultrasound examinations. Research is continuing to improve the equipment for general abdominal use.
