description: Receiver clock modeling (RCM) based on code observations requires a chip-scale atomic clock to improve the PVT solution. When using carrier phase observations, a more stable oscillator like a passive hydrogen maser (PHM) is necessary. We applied a PHM in an automotive experiment of about 80 minutes in an urban environment recording 10 Hz multi-GNSS data. Modeling the clock process noise in a linearized Kalman filter according to the spectral behavior of the PHM (i.e., RCM), improves position and velocity regarding precision and accuracy by 15% and 57%, respectively, as well as reliability by 30%. In situations with sparse, geometrically unfavorable observations, RCM prevents large position drifts. The convergence time of the carrier phase ambiguities is not affected. Conclusively, precision, accuracy, and reliability in kinematic precise point positioning can be improved by using an oscillator like a PHM. Future advancements in clock technology should make this approach more feasible for ordinary use cases.

description: The outbreak of coronavirus disease 2019 (COVID-19) maybe stressful for people of all ages and this ongoing COVID-19 pandemic has resulted in many quarantine and social isolation measures designed to keep individuals physically distanced from others for the foreseeable future. Although these initiatives are necessary to prevent the spread of novel coronavirus, they may be causing widespread mental health effects or psychological illness including anxiety, fear, loneliness, social phobia, hopelessness, depression, irritability, worry, anger, frustration, insomnia etc.
 The COVID-19 pandemic has effected all the domains of human life/personality including Mental, Physical, Social, occupational, Emotional and psychological as well and the common physical symptoms which occurs due to this pandemic are unsafe fatigue, frequent colds, nausea, chest pain, eating too much, crying a lot, smoking and drinking more than usual or physically striking out at others by hitting or throwing things and these are the clear indication of stressful life which have evoked due to COVID-19 pandemic

Moment condition tests for heavy tailed time series
Creators: name: Hill, Jonathan
name: Aguilar, Mike
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: We develop an asymptotically chi-squared test statistic for testing moment conditions E[mt(Θ0)] = 0 where scalar components of mt(Θ0) may have an infinite variance and mt(Θ0) may be weakly dependent. In general E[mt(Θ0)] need not exist under the alternative. A variety of tests can be heavy-tail robustified by our method, including white noise, GARCH affects, omitted variables, order selection, functional form, causation, volatility spillover and over-identification. The test statistic is derived from a tail-trimmed sample version of the moments evaluated at a consistent plug-in ^ΘT for Θ0. Depending on the test in question ^ΘT may be any consistent estimator like QML, LAD, GMM, and Empirical Likelihood as well as robust estimators like Least Trimmed Squares, Least Absolute Weighted Deviations, and Generalized Method of Tail-Trimmed Moments. Simple rules of thumb for selecting the trimming fractiles are presented, and in many cases when mt(Θ0) has infinite variance components the fractiles and/or ^Θ T can be chosen to ensure ^ΘT does not influence the test statistic's limit distribution. Thus, in heavy tailed cases ^ΘT does not need to have a Gaussian limit. We apply our statistic to tests of white noise, omitted variables and volatility spillover and find it obtains correct empirical size, while conventional tests exhibit sharp distortions.

description: The objective of this paper is to present a modern and concise new derivation for the explicit expression of the interior and exterior Newtonian potential generated by homogeneous ellipsoidal domains in $\mathbb{R}^N$ (with $N \geqslant 3$). The very short argument is essentially based on the application of Reynolds transport theorem in connection with Green-Stokes integral representation formula for smooth functions on bounded domains of $\mathbb{R}^N$, which permits to reduce the N-dimensional problem to a 1-dimensional one. Due to its physical relevance, a separate section is devoted to the the derivation of the demagnetizing factors of the general ellipsoid which are one of the most fundamental quantities in ferromagnetism.
The valuation of American barrier options using the decomposition technique

description: In this paper, we propose an alternative approach for pricing and hedging American barrier options. Specifi cally, we obtain an analytic representation for the value and hedge parameters of barrier options, using the decomposition technique of separating the European option value from the early exercise premium. This allows us to identify some new put-call "symmetry" relations and the homogeneity in price parameters of the optimal exercise boundary. These properties can be utilized to increase the computational efficiency of our method in pricing and hedging American options. Our implementation of the obtained solution indicates that the proposed approach is both efficient and accurate in computing option values and option hedge parameters. Our numerical results also demonstrate that the approach dominates the existing lattice methods in both accuracy and efficiency. In particular, the method is free of the difficulty that existing numerical methods have in dealing with spot prices in the proximity of the barrier, the case where the barrier options are most problematic.

description: The adhesion bonds connecting a lipid bilayer to an underlying surface may undergo a condensation transition resulting from an interplay between a short range attractive potential between them, and a long range fluctuation-induced potential of mean force. Here, we use computer simulations of a coarse-grained molecular model of supported lipid bilayers to study this transition in confined membranes, and in membranes subjected to a non-vanishing surface tension. Our results show that confinement may alter significantly the condensation transition of the adhesion bonds, whereas the application of surface tension has a very minor effect on it. We also investigate domain formation in membranes under negative tension which, in free membranes, causes enhancement of the amplitude of the membrane thermal undulations. Our results indicate that in supported membranes, this effect of a negative surface tension on the fluctuation spectrum is largely eliminated by the pressure resulting from the mixing entropy of the adhesion bonds.

description: We revisit the setting of fairly allocating indivisible items when agents have different weights representing their entitlements. First, we propose a parameterized family of relaxations for weighted envy-freeness and the same for weighted proportionality; the parameters indicate whether smaller-weight or larger-weight agents should be given a higher priority. We show that each notion in these families can always be satisfied, but any two cannot necessarily be fulfilled simultaneously. We then introduce an intuitive weighted generalization of maximin share fairness and establish the optimal approximation of it that can be guaranteed. Furthermore, we characterize the implication relations between the various weighted fairness notions introduced in this and prior work, and relate them to the lower and upper quota axioms from apportionment.

LIQUID ROCKET ENGINE
COMBUSTION INSTABILITIES

description: This work was realized in the framework of the REST (Rocket Engine Stability Initiative) working group on combustion instabilities in liquid rocket engines. The HF-10 test case is a study of a typical injection element from a liquid rocket engine, subject to pulsating mass flow rates at the inlet. The test comprises 3 sub-cases. In the first case, the outer flow (CH4) is pulsated at 5kHz. The second case consists in modulating the inner flow (O2) at 1kHz and in the third case the inner flow is pulsated at 5kHz. The HF-10 test case was simulated using the AVBP solver from CERFACS. The numerical approach relies on real-gas thermodynamics based on the SRK equation of state. Two meshes were used: one coarse and one fine, comprising respectively 700,000 and 5M points. Two combustion models are investigated: a beta-pdf based equilibrium chemistry model and an Arrhenius based finite-rate chemistry model, with an ARC scheme specifically derived for the present cases. The computed flame reaches about one third of the combustion chamber length for the isoline at 1500K. The flame expands quickly after the injection plane, and large scale intermittencies are observed. There is no significant difference between the two meshes in terms of flame length and topology. A shorter flame occurs when the inner injection is pulsated, as well as wrinkled structures near the injector. Phase-locked averages show that pulsation at the inlet induces periodic oscillations of the heat release rate along the flame. First results indicate that the two chemical approaches lead to similar flame topologies. The finite-rate chemistry flame structure confirms that combustion occurs in a pure diffusion flame regime in this adiabatic configuration. The finite-rate chemistry allows to accurately describe the interaction between turbulence and the flame and the induced deviations from a reference counter-flow flame.

description: A general strategy for the realization of electric and magnetic quasi-trapped modes located at the same spectral position is presented. This strategy's application makes it possible to design metasurfaces allowing switching between the electric and magnetic quasi-trapped modes by changing the polarization of the incident light wave. The developed strategy is based on two stages: the application of the dipole approximation for determining the conditions required for the implementation of trapped modes at certain spectral positions and the creation of the energy channels for their excitation by introducing a weak bianisotropy in nanoparticles. Since excitation of trapped modes results in a concentration of electric and magnetic energies in the metasurface plane, the polarization switching provides possibilities to change and control the localization and distribution of optical energy at the sub-wavelength scale. A practical method for spectral tuning of quasi-trapped modes in metasurfaces composed of nanoparticles with a preselected shape is demonstrated. As an example, the optical properties of a metasurface composed of silicon triangular prisms are analyzed and discussed.
title: Genetic mapping studies in the AS/AGU rat
Creators: name: Canham, Maurice
Publisher: name: University of Glasgow
Year: 1997
Subjects: subject: Genetics.

description: The AS/AGU rat arose by spontaneous mutation from a closed colony of AS rats in the Laboratory of Human Anatomy, The University of Glasgow, in 1990. These rats had locomotor abnormalities and appeared to have a striatal dopamine deficiency syndrome, symptoms and pathology reminiscent of human Parkinson's disease. Test crosses between AS/AGU and AS rats indicated that the mutant locus, agu, was inherited in an autosomal recessive fashion with no evidence of maternal or X-linked involvement. Two reference strains, BN and F344, were used to set up backcrosses with AS/AGU, namely, [AS/AGUxF1(AS/AGUxBN)] and [AS/AGUxF1(AS/AGUxF344)]. Previously, 75 microsatellites markers spanning the rat genome were tested for informativeness between AS/AGU and the strains BN and F344. In this study, 19 other microsatellites were typed on these strains, 9 of which displayed size differences and could therefore be mapped relative to agu. Two candidate chromosomes had been thought to harbour agu, one of which was eliminated in this report. Initially, four markers from the other chromosome had aU shown linkage with agu but none were close enough to commence chromosome walking to the disease locus. This report describes the analysis of pre-existing microsatellites and the search for new ones associated with a gene family believed to be adjacent to agu. A total of twelve markers, associated with this gene family, were analysed for size or sequence variation between AS/AGU and reference strains. None proved informative. It was concluded that members of this gene family had not diverged sufficiently between these strains. Another reference strain, DA, has been shown to display size differences from the AS strain from members of this gene family and other markers believed to be near agu. A backcross program using this reference strain is now underway. To date, another gene-based marker has been shown to be less than 0.5 cM from agu and physical mapping is now underway to track down a gene harbouring this mutation. The eventual discovery of such a gene and its role in normal physiology will prove valuable in the understanding of basal ganglia disorders.

description: In multiwinner approval voting, the goal is to select $k$-member committees based on voters' approval ballots. A well-studied concept of proportionality in this context is the justified representation (JR) axiom, which demands that no large cohesive group of voters remains unrepresented. However, the JR axiom may conflict with other desiderata, such as coverage (maximizing the number of voters who approve at least one committee member) or social welfare (maximizing the number of approvals obtained by committee members). In this work, we investigate the impact of imposing the JR axiom (as well as the more demanding EJR axiom) on social welfare and coverage. Our approach is threefold: we derive worst-case bounds on the loss of welfare/coverage that is caused by imposing JR, study the computational complexity of finding 'good' committees that provide JR (obtaining a hardness result, an approximation algorithm, and an exact algorithm for one-dimensional preferences), and examine this setting empirically on several synthetic datasets.

I will argue that this idea does not fully utilize critical potentials that are available to improve the fundamental axiom. I will propose an alternative interpretation which I call the ‘critical interpretation’ that conserves the progressive aspects of Linsbichler’s proposal while eliminating undesirable ones.

description: Despite numerous studies, the sources of IceCube cosmic neutrinos are mostly unidentified. Utilizing recently released IceCube neutrino and CHIME fast radio burst (FRB) catalogs, we examine the possibility of an association between neutrinos and CHIME/FRB catalog 1 FRBs for both the entire FRB population and individual FRBs using the unbinned maximum likelihood method. Our results do not directly support the possibility of the above-mentioned association with three weighting schemes: equal, total radio fluence, and event rate. We then attempt to constrain the diffuse muon neutrino flux upper limit from CHIME/FRB catalog 1 FRBs. After considering a completeness correction, we find the 95% diffuse muon neutrino flux upper limit at 100 TeV for all FRB sources in the universe to be $\sim 1.01\times10^{-18}\;\mathrm{GeV}^{-1}\;\mathrm{cm}^{-2}\;\mathrm{s}^{-1}\;\mathrm{sr}^{-1}$, or $\sim 70.3\%$ of the 10-year diffuse neutrino flux observed by IceCube. Our results match the non-detection results of other studies, but we do not rule out FRBs being a significant contributor to the diffuse neutrino flux measured by IceCube.

description: We derive an analytical calculation formula for the channel capacity of a classical channel without any iteration while its existing algorithms require iterations and the number of iteration depends on the required precision level. Hence, our formula is its first analytical formula without any iteration. We apply the obtained formula to examples and see how the obtained formula works in these examples. Then, we extend it to the channel capacity of a classical-quantum (cq-) channel. Many existing studies proposed algorithms for a cq-channel and all of them require iterations. Our extended analytical algorithm have also no iteration and output the exactly optimum values.

description: We present first results on polarization swings in optical emission of blazars obtained by RoboPol, a monitoring program of an unbiased sample of gamma-ray bright blazars specially designed for effective detection of such events. A possible connection of polarization swing events with periods of high activity in gamma rays is investigated using the dataset obtained during the first season of operation. It was found that the brightest gamma-ray flares tend to be located closer in time to rotation events, which may be an indication of two separate mechanisms responsible for the rotations. Blazars with detected rotations have significantly larger amplitude and faster variations of polarization angle in optical than blazars without rotations. Our simulations show that the full set of observed rotations is not a likely outcome (probability $\le 1.5 \times 10^{-2}$) of a random walk of the polarization vector simulated by a multicell model. Furthermore, it is highly unlikely ($\sim 5 \times 10^{-5}$) that none of our rotations is physically connected with an increase in gamma-ray activity.

description: Current science communication has a number of drawbacks and bottlenecks which have been subject of discussion lately: Among others, the rising number of published articles makes it nearly impossible to get a full overview of the state of the art in a certain field, or reproducibility is hampered by fixed-length, document-based publications which normally cannot cover all details of a research work. Recently, several initiatives have proposed knowledge graphs (KG) for organising scientific information as a solution to many of the current issues. The focus of these proposals is, however, usually restricted to very specific use cases. In this paper, we aim to transcend this limited perspective and present a comprehensive analysis of requirements for an Open Research Knowledge Graph (ORKG) by (a) collecting and reviewing daily core tasks of a scientist, (b) establishing their consequential requirements for a KG-based system, (c) identifying overlaps and specificities, and their coverage in current solutions. As a result, we map necessary and desirable requirements for successful KG-based science communication, derive implications, and outline possible solutions.

description: The aim of this talk is to present the status of the SKAO project and the SKA Regional Centre Network. The SKA project is an international effort to build two radio-interferometers that will be able to make revolutionary contributions to Astrophysics, Astrobiology, and Fundamental Physics. In January 2021 the SKA Observatory (SKAO) was established as the second intergovernmental organisation (IGO) in astronomy (after the ESO) in January 2021.
 SKA-Low will consist of 130.000 low-frequency dipoles in Australia, and SKA-Mid will consist of 133 SKA+64 MeerKAT dishes in South Africa. The construction phase commenced in July 2021 and the procurement and tender for the contracts have been initiated, and at the time of writing 5 construction contracts have been pre-allocated to Spain. In addition, the observatory is planning to start a development program for new instrumentation.

 The high data-rate and complexity of SKA will necessarily transform how scientists access, analyse and share data from observations, being considered a Big Data machine. A network of SKA Regional Centres (SRCs) is being established to take the science data products that will emerge from the SKAO to the final state required for science analysis. Those will constitute the core of SKA science, since analysis of SKA data will not be feasible out of them. The SRC Network will be part of an end-to-end system composed by the SKAO and the SRCs. The SRCs will provide the SKA community with access to data, computational resources and support to use the SKA and its data products, as well as a platform for collaborative science. To develop the SRC Network, several countries, including Spain, are building SRC prototypes that are the foundation of the work led by the SRC Steering Committee (SRCSC). In 2020, the SRCSC established seven working groups with wide participation from the Spanish community, and recently the SRCSC started a new phase to prototype specific components of the SRC Network.
Random matrix approach to multivariate categorical data analysis

description: Correlation and similarity measures are widely used in all the areas of sciences and social sciences. Often the variables are not numbers but are instead qualitative descriptors called categorical data. We define and study similarity matrix, as a measure of similarity, for the case of categorical data. This is of interest due to a deluge of categorical data, such as movie ratings, top-10 rankings and data from social media, in the public domain that require analysis. We show that the statistical properties of the spectra of similarity matrices, constructed from categorical data, follow those from random matrix theory. We demonstrate this approach by applying it to the data of Indian general elections and sea level pressures in North Atlantic ocean.

description: H.G. Santarriaga, a Mexican comic book artist known for his visual style and ability to address a variety of genders, has been exploring various visual expressions to speak about the different forms of violence happening against women, in the contemporary Mexico. In the last two years, Santarriaga published a collection of graphic novels named Sueños rotos which, from the point of view of a female protagonist, based on true stories and verified facts, speak about prostitution and human trafficking. The purpose of this paper is to analyse the visual and narrative mechanisms that the author uses to speak about violence against women and study the contrasts made from different forms of media and its approach to this problem. We will explore the process in which though the use of colour, contrast and the use of testimony are managed to create a voice that coincides with the point of view of a victim who is experiencing restriction, violence and the annulation of her human condition. Furthermore, we will focus our attention on how these are represented on the graphic novels and the visual and narrative devices that the author uses in order to analyse if these graphic novels could be considered as an alternative registration of the collective memory.

description: Food allergies are a major health issue worldwide. Modern breeding techniques such as genome editing via CRISPR/Cas9 have the potential to mitigate this by targeting allergens in plants. This study addressed the major allergen Bra j I, a seed storage protein of the 2S albumin class, in the allotetraploid brown mustard (Brassica juncea). Cotyledon explants of an Indian gene bank accession (CR2664) and the German variety Terratop were transformed using Agrobacterium tumefaciens harboring binary vectors with multiple single guide RNAs to induce either large deletions or frameshift mutations in both Bra j I homoeologs. A total of 49 T0 lines were obtained with up to 3.8% transformation efficiency. Four lines had large deletions of 566 up to 790 bp in the Bra j IB allele. Among 18 Terratop T0 lines, nine carried indels in the targeted regions. From 16 analyzed CR2664 T0 lines, 14 held indels and three had all four Bra j I alleles mutated. The majority of the CRISPR/Cas9-induced mutations were heritable to T1 progenies. In some edited lines, seed formation and viability were reduced and seeds showed a precocious development of the embryo leading to a rupture of the testa already in the siliques. Immunoblotting using newly developed Bra j I-specific antibodies revealed the amount of Bra j I protein to be reduced or absent in seed extracts of selected lines. Removing an allergenic determinant from mustard is an important first step towards the development of safer food crops.

description: Hyper spectral imaging is a remote sensing technology, providing variety of applications such as material identification, space object identification, planetary exploitation etc. It deals with capturing continuum of images of the earth surface from different angles. Due to the multidimensional nature of the image, multi-way arrays are one of the possible solutions for analyzing hyper spectral data. This multi-way array is called tensor. Our approach deals with implementing three decomposition models LMLRA, BTD and CPD to the sample data for choosing the best decomposition of the data set. The results have proved that Block Term Decomposition (BTD) is the best tensor model for decomposing the hyper spectral image in to resultant factor matrices.

description: We formulate em algorithm in the framework of Bregman divergence, which is a general problem setting of information geometry. That is, we address the minimization problem of the Bregman divergence between an exponential subfamily and a mixture subfamily in a Bregman divergence system. Then, we show the convergence and its speed under several conditions. We apply this algorithm to rate distortion and its variants including the quantum setting, and show the usefulness of our general algorithm. In fact, existing applications of Arimoto-Blahut algorithm to rate distortion theory make the optimization of the weighted sum of the mutual information and the cost function by using the Lagrange multiplier. However, in the rate distortion theory, it is needed to minimize the mutual information under the constant constraint for the cost function. Our algorithm directly solves this minimization. In addition, we have numerically checked the convergence speed of our algorithm in the classical case of rate distortion problem.

description: This paper proposes a novel approach to person re-identification, a fundamental task in distributed multi-camera surveillance systems. Although a variety of powerful algorithms have been presented in the past few years, most of them usually focus on designing hand-crafted features and learning metrics either individually or sequentially. Different from previous works, we formulate a unified deep ranking framework that jointly tackles both of these key components to maximize their strengths. We start from the principle that the correct match of the probe image should be positioned in the top rank within the whole gallery set. An effective learning-to-rank algorithm is proposed to minimize the cost corresponding to the ranking disorders of the gallery. The ranking model is solved with a deep convolutional neural network (CNN) that builds the relation between input image pairs and their similarity scores through joint representation learning directly from raw image pixels. The proposed framework allows us to get rid of feature engineering and does not rely on any assumption. An extensive comparative evaluation is given, demonstrating that our approach significantly outperforms all state-of-the-art approaches, including both traditional and CNN-based methods on the challenging VIPeR, CUHK-01 and CAVIAR4REID datasets. Additionally, our approach has better ability to generalize across datasets without fine-tuning.
