subject: FOS: Computer and information sciences

description: Purpose: SARS-COV-2, a severe acute respiratory syndrome, has caused more than 1 million to be infected worldwide. Corona
Virus Disease, known as COVID-19, has cases that are worldwide and widespread. What is worse, this number continues to increase.
Early diagnosis of COVID-19 and finding high-risk patients with a worse prognosis for early prevention is vital. It is essential to screen as
many as suspect cases for appropriate quarantine and treatment measures to control the spread of the disease. The viral test based on
samples taken from the lower respiratory tract is the critical standard of diagnosis. However, the availability and quality of laboratory tests in
the infected area may cause inaccurate results, false positive.
Methods: In this study, a Deep Learning (DL) method for COVID-19 diagnostic and prognostic analysis using Computed Tomography (CT)
scans is studied. Based on the COVID-19 CT images, it is aimed to diagnose COVID- 19 at an early stage. Thus, it may take place before
a clinical diagnosis before pathogenic testing.
Results: For the testing probability of the disease, 5800 CT images were taken from Kaggle web. 4640 (80%) CT images are used as the
training step, while 1160 (20%) images are benefitted for the testing step. AlexNet has achieved an overall accuracy of 94. 74%, with 87.
37% sensitivity and 87. 45% as specificity while Inception-V4 has an overall accuracy of 84. 14%, with 87. 09% sensitivity and 84. 14% as
specificity. These results show the high value of using Deep learning for early diagnosis of COVID-19. Deep learning is used as a beneficial
tool for fast screening COVID-19. In this study, it is benefitted to find potential high-risk patients.

description: In Noisy Intermediate-Scale Quantum (NISQ) era, quantum processing units (QPUs) suffer from, among others, highly limited connectivity between physical qubits. To make a quantum circuit effectively executable, a circuit transformation process is necessary to transform it, with overhead cost the smaller the better, into a functionally equivalent one so that the connectivity constraints imposed by the QPU are satisfied. While several algorithms have been proposed for this goal, the overhead costs are often very high, which degenerates the fidelity of the obtained circuits sharply. One major reason for this lies in that, due to the high branching factor and vast search space, almost all these algorithms only search very shallowly and thus, very often, only (at most) locally optimal solutions can be reached. In this paper, we propose a Monte Carlo Tree Search (MCTS) framework to tackle the circuit transformation problem, which enables the search process to go much deeper. The general framework supports implementations aiming to reduce either the size or depth of the output circuit through introducing SWAP or remote CNOT gates. The algorithms, called MCTS-Size and MCTS-Depth, are polynomial in all relevant parameters. Empirical results on extensive realistic circuits and IBM Q Tokyo show that the MCTS-based algorithms can reduce the size (depth, resp.) overhead by, on average, 66% (84%, resp.) when compared with tket, an industrial level compiler.

description: In this talk I will discuss an example of the use of fully nonlinear parabolic flows to prove geometric results. I will emphasise the fact that there is a wide variety of geometric parabolic equations to choose from, and to get the best results it can be very important to choose the best flow. I will illustrate this in the setting of surfaces in a three-dimensional sphere. There are quite a few relevant results for surfaces in the sphere satisfying various kinds of curvature equations, including totally umbillic surfaces, minimal surfaces and constant mean curvature surfaces, and intrinsically flat surfaces. Parabolic flows can strengthen such results by allowing classes of surfaces satisfying curvature inequalities rather than equalities: This was first done by Huisken, who used mean curvature flow to deform certain classes of surfaces to totally umbillic surfaces. This motivates the question ``What is the optimal result of this kind?'' -- that is, what is the weakest pointwise curvature condition which defines a class of surfaces which retracts to the space of great spheres? The answer to this question can be guessed in view of the examples. To prove it requires a surprising choice of evolution equation, forced by the requirement that the pointwise curvature condition be preserved. I will conclude by mentioning some other geometric situations in which strong results can be proved by choosing the best possible evolution equation.

Die Buckelwiesen — nicht Eiszeitalter, sondern Gegenwart

description: In den Bayrischen Kalkalpen bis ins Vorland hinaus und nach Österreich hinüber finden sich ausgedehnte Gebiete mit sog. „Buckelwiesen", ein mit 1-1 ½ m hohen Buckeln und entsprechenden Mulden bedecktes Gelände. Sie tragen eine ebenso reizvolle wie artenreiche und differenzierte Flora. Diese Buckelwiesen waren mehr als 20 Jahre lang ein Gegenstand wissenschaftlicher Diskussion. Man fragte sich, ob sie als alte Waldböden oder als Bildungen der Eiszeit anzusehen seien. Eine Anzahl von Geographen, Geologen und Bodenkundlern hielt sie für eine Sedimentationsform oder für Perigiazialbildungen der letzten Vereisung. Aber nirgendwo wurden Buckelwiesen im Verbreitungsgebiet der nordeuropäischen Vereisung bekannt. Sie scheinen auf kalkhaltige Sedimente, besonders Moränen, Schotterterrassen, Schuttkegel und Ähnliches, beschränkt zu sein. Seit 1939 deutet die Verfasserin sie als durch rezente Verkarstung entstanden. Dieser Auffassung stimmte A. Penck 1940 zu. Im Jahre 1958 fand S. Müller bei einer Untersuchung des Buckelwiesengeländes der Pokljuka in den Julischen Alpen bei Bled in Jugoslawien schlüssige Beweise für diese Auffassung.

description: This study examines the performance of working memory components in children with autism spectrum disorder in comparison to normal children. This study aimed at exploring the functioning of working memory in children with autism spectrum disorder. The sample consisted of 34 children having the same age (distributed to 17 normal children, and 17 children with autism spectrum disorder). We administered the following three tests (forward digit span, backward digit span, and pattern task) were conducted. The results of this study showed that there are clear deficiencies in working memory in children with autism spectrum disorder. These deficits appear in tasks that require working memory intervention; whether it is related to the maintenance of speech-based materials (verbal information), or storage and maintenance of visual and spatial information in working memory for a short period of time. Finally, we discussed the results based on the results of previous studies about working memory and autism spectrum disorder. The conclusions of our study confirmed the results of the previous studies.
title: Geodesics in some exact rotating solutions of Einstein's equations
Creators: name: Steadman, Brian Richard
Publisher: name: The Open University
Year: 2000

description: In examining some exact solutions of Einstein's field equations, the main approach used here is to study the geodesic motion of light, and sometimes test particles. Difficulties in solving the geodesic equations are avoided by using computer algebra to solve the equations numerically and to plot them in two- or three-dimensional diagrams. Interesting features revealed by these diagrams may then be investigated analytically. Application of this technique to the van Stockum solution for a rotating dust cylinder and to Bonnor's rotating dust cloud seems to reveal different constraints on the spatial distribution of geodesics with different parameters. Analysis then continns that, in the highest mass van Stockum case, null geodesics in the vacuum exterior are radially confined according to their initial conditions. Null geodesics plotted in Bonnor's dust cloud seem to be repelled before they can reach the centre. Although there is no event horizon, analysis reveals a central region which cannot be penetrated by light from spatial infinity and from which light cannot escape to spatial infinity. The gravitomagnetic clock effect is studied in van Stockum spacetime. The effect is found to be frame dependent and can be reduced to zero by a suitable coordinate transformation.

description: Recent advances in data analytics and computer-aided diagnostics stimulate the vision of patient-centric precision healthcare, where treatment plans are customized based on the health records and needs of every patient. In physical rehabilitation, the progress in machine learning and the advent of affordable and reliable motion capture sensors have been conducive to the development of approaches for automated assessment of patient performance and progress toward functional recovery. The presented study reviews computational approaches for evaluating patient performance in rehabilitation programs using motion capture systems. Such approaches will play an important role in supplementing traditional rehabilitation assessment performed by trained clinicians, and in assisting patients participating in home-based rehabilitation. The reviewed computational methods for exercise evaluation are grouped into three main categories: discrete movement score, rule-based, and template-based approaches. The review places an emphasis on the application of machine learning methods for movement evaluation in rehabilitation. Related work in the literature on data representation, feature engineering, movement segmentation, and scoring functions is presented. The study also reviews existing sensors for capturing rehabilitation movements and provides an informative listing of pertinent benchmark datasets. The significance of this paper is in being the first to provide a comprehensive review of computational methods for evaluation of patient performance in rehabilitation programs.

description: Materials based on the cubic perovskite unit cell continue to provide the basis for technologically important materials with two notable recent examples being lead-based relaxor piezoelectrics and lead-based organic-inorganic halide photovoltaics. These materials carry considerable disorder, arising from site substitution in relaxors and molecular vibrations in the organic-inorganics, yet much of our understanding of these systems derives from the initial classic work of Prof. Roger A. Cowley, who applied both theory and neutron scattering methods while at Chalk River Laboratories to the study of lattice vibrations in SrTiO$_{3}$. Neutron scattering continues to play a vital role in characterizing lattice vibrations in perovskites owing to the simple cross section and the wide range of energy resolutions achievable with current neutron instrumentation. We discuss the dynamics that drive the phase transitions in the relaxors and organic-inorganic lead-halides in terms of neutron scattering and compare them to those in phase transitions associated with a ``central peak" and also a soft mode. We review some of the past experimental work on these materials and present new data from high-resolution time-of-flight backscattering spectroscopy taken on organic-inorganic perovskites. We will show that the structural transitions in disordered lead-based perovskites are driven by a broad frequency band of excitations.

description: The self-similar infall model (SSIM) is normally discussed in the context of radial orbits in spherical symmetry. However it is possible to retain the spherical symmetry while permitting the particles to move in Keplerian ellipses, each having the squared angular momentum peculiar to their 'shell'. The spherical 'shell', defined for example by the particles turning at a given radius, then moves according to the radial equation of motion of a 'shell' particle. The 'shell' itself has no physical existence except as an ensemble of particles, but it is convenient to sometimes refer to the shells since it is they that are followed by a shell code. In this note we find the distribution of squared angular momentum as a function of radius that yields the NFW density profile for the final dark matter halo. It transpires that this distribution is amply motivated dimensionally. An effective 'lambda' spin parameter is roughly constant over the shells. We also study the effects of angular momentum on the relaxation of a dark matter system using a three dimensional representation of the relaxed phase space.

description: This paper introduces a dynamic zero-sum game framework inspired by the Lanchester combat model to resolve issues that relate to logically consistent market share models. Our new theorem. shows that three of four axioms in Bell, Keeney and Little's (1975) "market share theorem" are either incomplete or unnecessary; concerns about the nonlinearity and asymmetry aftermath of the market share system also are incorporated into in our analysis. Implications of this new theorem resolve some of the confusion surrounding the logically consistent market share models proposed by Naert and Bultez (1973) and McGuire and Weiss (1976), and the recent empirical paper by Brodie and de Kluyver (1987). More specifically, this pap;er explains the ways to incorporate both range and sum constraints to complete the logical consistency problem, and demonstrates the feasibility of adopting model robustness and descriptive validity which previously have been thought to be incompatible in construction of market share response models.
title: Community acquired respiratory syncytial virus infections : detection by multiplex PCR and strain characterisation by partial G gene sequencing
Creators: name: Stockton, Joanne Dawn
Publisher: name: The Open University
Year: 2000

description: The aim of this project was to design an assay for the detection of respiratory syncytial virus (RSV) RNA extracted directly from clinical specimens. The assay was intended to address the question of whether RSV is a significant cause of respiratory illness in all age groups of the general community.

The amplification assay for the detection of RSV subtypes A and B was designed using primers located in the nucleocapsid gene. This RSV PCR was incorporated into a multiplex PCR together with primers specific to influenza A H1N1, H3N2 and influenza B, The multiplex assay was optimised and validated, and different amplicon detection methods were investigated with a view to develop a high throughput protocol.

The multiplex PCR assay was then applied to combined nose and throat swabs collected from members of the general community with influenza or influenza like illness, over a three year period (1995-1998). Analysis of these results revealed the co-circulation of RSV and influenza during the winters. RSV was shown to be an important contributor to respiratory illness in all age groups, being detectable in about 20% of patients with influenza like illness.

The RSV positive samples from the three winter seasons studied were processed to obtain sequence data suitable for molecular epidemiological analysis. A strategy to amplify and sequence the first variable region of the glycoprotein gene was developed. PCR amplification was successfully performed directly using stored clinical samples. Phylogenetic analyses of the amplicons revealed that different strain types circulated during each winter season.

description: Critical collapse of a self-gravitating scalar field in a (2+1)-dimensional spacetime with negative cosmological constant seems to be dominated by a continuously self-similar solution of the field equations without cosmological constant. However, previous studies of linear perturbations in this background were inconclusive. We extend the continuously self-similar solutions to solutions of the field equations with negative cosmological constant, and analyse their linear perturbations. The extended solutions are characterized by a continuous parameter. A suitable choice of this parameter seems to improve the agreement with the numerical results. We also study the dynamics of the apparent horizon in the extended background.

description: The conventional wisdom among economists today is that wages have become less sensitive to aggregate economic conditions, mainly because of changes in labor market structure and changes in wage contracting mechanisms brought about by countercyclical policy and social insurance. This is re-examined here by using a wider range of data sets and a longer time frame than in any previous study and by paying close attention to differences in the way the prewar and postwar wage series were constructed and the effects of aggregation across industries. The results show that the response of nominal wages to unemployment and output, conditional on previous inflation, is about the same today as it was 100 years ago.
Non-axisymmetric instabilities in shocked accretion flows with differential rotation

description: The linear stability of a shocked isothermal accretion flow onto a black hole is investigated in the inviscid limit. The outer shock solution, which was previously found to be stable with respect to axisymmetric perturbations, is, however, generally unstable to non-axisymmetric ones. Eigenmodes and growth rates are obtained by numerical integration of the linearized equations. The mechanism of this instability is based on the cycle of acoustic waves between their corotation radius and the shock. It is a form of the Papaloizou-Pringle instability, modified by advection and the presence of the shock. As such it can be generalized to non isothermal shocked accretion flows. Blobs and vortices are generated by the shock as a by-product of the instability.

description: Since the initial development of charged particle colliders in the middle of the 20th century, these advanced scientific instruments have been at the forefront of scientific discoveries in high energy physics. Collider accelerator technology and beam physics have progressed immensely and modern facilities now operate at energies and luminosities many orders of magnitude greater than the pioneering colliders of the early 1960s. In addition, the field of colliders remains extremely dynamic and continues to develop many innovative approaches. Indeed, several novel concepts are currently being considered for designing and constructing even more powerful future colliders. In this paper, we first review the colliding beam method and the history of colliders, and then present the major achievements of operational machines and the key features of near-term collider projects that are currently under development. We conclude with an analysis of numerous proposals and studies for far-future colliders. The evaluation of their respective potentials reveals tantalizing prospects for further significant breakthroughs in the collider field.

description: Introducción

En los últimos años se observa el auge de las revistas científicas peruanas muchas de las cuales se encuentran registradas en importantes bases de datos y directorios. Sin embargo, todavía son poco visibles en el ámbito internacional por ello es importante identificar procedimientos que coadyuven a mejorar su visibilidad.

Objetivo

Describir los principales indicadores de visibilidad que están aplicando las revistas indizadas en Scielo Perú.

Método

Muestra conformada por 34 revistas científicas incluidas en Scielo-Perú. Análisis exploratorio: estadístico-descriptivo y de contenido. Datos recopilados hasta enero 2021.

Resultados preliminares

El 97.1% usan Open Journal Systems(OJS). Solo el 23.5% publican en HTML. El 55.8 % utiliza el ORCID en los metadatos de sus publicaciones. Todas las revistas asignan DOI a sus artículos recientes, pero no a las publicaciones anteriores.

Conclusión 

El uso adecuado de los indicadores mencionados mejora la visibilidad de las revistas, lo cual repercute positivamente en la incremento de citas. Sin embargo, el uso de estos indicadores en las revistas peruanas revisadas es incipiente, a pesar que las bases de datos lo solicitan para su indización.

Abstract- To cope with the ongoing changing demands of the internet, ‘in-network caching’ has been presented as an application solution for two decades. With the advent of information-centric network (ICN) architecture, ‘in-network caching’ becomes a network level solution. Some unique features of ICNs, e.g., rapidly changing cache states, higher request arrival rates, smaller cache sizes, and other factors, impose diverse requirements on the content eviction policies. In particular, eviction policies should be fast and lightweight. In this study, we propose cache replication and eviction schemes, Conditional Leave Cope Everywhere (CLCE) and Least Frequent Recently Used (LFRU), which are well suited for the ICN type of cache networks (CNs). The CLCE replication scheme reduces the redundant caching of contents; hence improves the cache spaceutilization. LFRU approximates the Least Frequently Used (LFU) scheme coupled with the Least Recently Used (LRU) scheme and is practically implementable for rapidly changing cache networks like ICNs.

description: This paper models physical content policies in a bilateral monopoly setting, using a cooperative game approach. For just binding or nonbinding content requirements, the policy does not induce any dead-weight lossbut alters the profit distribution in favor of the domestic supplier. This result holds as long as the inputs concerned by the policy are good substitutes in production, and when the disagreement point corresponds to low content requirements and low marginal cost for the domestic input.
Silicate Melting and Vaporization during Rocky Planet Formation

description: Collisions that induce melting and vaporization can have a substantial effect on the thermal and geochemical evolution of planets. However, the thermodynamics of major minerals are not well known at the extreme conditions attained during planet formation. We obtained new data at the Sandia Z Machine and use published thermodynamic data for the major mineral forsterite (Mg$_2$SiO$_4$) to calculate the specific entropy in the liquid region of the principal Hugoniot. We use our calculated specific entropy of shocked forsterite, and revised entropies for shocked silica, to determine the critical impact velocities for melting or vaporization upon decompression from the shocked state to 1 bar and the triple points, which are near the pressures of the solar nebula. We also demonstrate the importance of the initial temperature on the criteria for vaporization. Applying these results to $N$-body simulations of terrestrial planet formation, we find that up to 20 to 40% of the total system mass is processed through collisions with velocities that exceed the criteria for incipient vaporization at the triple point. Vaporizing collisions between small bodies are an important component of terrestrial planet formation.

ADVERTISING'S EFFECT ON THE PRODUCT EVOLUTIONARY CYCLE

description: Criticism of the product life cycle (PLC) concept concerns problems with theory, empirical validation, and practical use. It has been suggested that the product evolutionary cycle (PEC), an alternative concept based on the field of biology, provides a more complete picture of marketing mix effects and competition on product sales (Tellis and Crawford 1981 ). In this research, the U.S. cigarette industry is used as the arena in which to assess empirically the PEC framework. Advertising-sales causation is tested on three levels of segment competition: (1) individual brand (2) intracategory, and (3) intercategory competition. Our findings indicate that more distantly related "organisms" compete as well as those closely related in terms of background. Specifically, we demonstrate a gradual but marked decrease in the effect of advertising on sales as products with more distant lineage co-exist and compete. The PEC is demonstrated to be an information-laden framework to use in making marketing mix decisions.

Noncommutative QCD corrections to the gluonic decays of heavy quarkonia

description: We compute the Noncommutative QCD (NCQCD) contributions to the three gluon decay modes of heavy quarkonia. For triplet quarkonia (ortho-quarkonia), the NCQCD correction to the QCD three gluon decay mode, like the standard model contribution, is infrared finite. In the case of singlet quarkonia (para-quarkonia), whose QCD three gluon decay mode has infrared singularities which are removed using one-loop corrections to the two gluon mode, we find that NCQCD contribution is also infrared finite. The calculations are performed in the weak binding limit and do not require the introduction of additional effective couplings.

description: In this first paper of a series, we report on the use of quasar spectra obtained with the UVES high resolution spectrograph and available through the ESO VLT archive to build the first sample of sub-DLA systems, absorbers with HI column densities > 10^{19} cm^{-2} but lower than the classical definition of damped Ly-alpha systems (DLAs) 2x10^{20} cm^{-2}. A systematic investigation of the properties of these systems and a comparison with those of the DLAs (Paper II of this series; Peroux et al. 2003b) is expected to provide new clues on the association of high column density absorbers with galaxies and on the overall evolution of the neutral hydrogen gas mass and metal content in the Universe. In the spectra of 22 quasars which were found suitable for a sub-DLA search, we identified 12 sub-DLAs and 1 borderline case between the DLA and sub-DLA systems in the redshift interval z = 1.8-4.3. We measured the column densities of HI and up to 16 ions of low-, intermediate- and high-ionization. We further investigated the significance of the ionization corrections in the determination of the chemical abundances from the low-ionization ions in the sub-DLA HI column density range. Using the predictions of different ion ratios as a function of the ionization parameter computed with the CLOUDY software package, we have estimated that with the exception of one case, the ionization corrections to the abundances of 9 systems for which we were able to constrain the ionization parameter, are lower than 0.2 dex for all of the elements except AlII and ZnII down to HI column densities of log N(HI) = 19.3 cm^{-2}. We finally present the first sub-DLA chemical abundance database which contains the abundance measurements of 11 different elements (O, C, Si, N, S, Mg, Al, Fe, Ni, Zn, and Cr).

Quartäre kalkige Äolianite von N-Menorca (Balearen, westliches Mittelmeer)
Creators: name: Henningsen, Dierk

description: Vom Norden der Insel Menorca (Balearen, westliches Mittelmeer) werden drei Serien von kalkigen Äolianiten beschrieben. In ihrer petrographischen Zusammensetzung unterscheiden sich Proben aus der älteren von solchen aus den beiden jüngeren Serien aufgrund des fast völligen Fehlens von silikatischen Mineralen und Gesteinsresten sowie — innerhalb der Biogene — durch ein Vorherrschen von Schalen von Foraminiferen gegenüber Resten von Kalkalgen. Vermutlich entstanden die Jüngsten Äolianite während des letzten Glazials, während die Jüngeren in das frühe Pleistozän und die Älteren an den Übergang Pliozän/ Pleistozän gestellt werden müssen. Damit wird deutlich, daß es offenbar auf den Balearen nicht regelmäßig in jedem Glazial zur Bildung von Äolianiten gekommen ist.
