description: We present a new criterion that determines whether a fermionic state is a convex combination of pure Gaussian states. This criterion is complete and characterizes the set of convex-Gaussian states from the inside. If a state passes a program it is a convex-Gaussian state and any convex-Gaussian state can be approximated with arbitrary precision by states passing the criterion. The criterion is presented in the form of a sequence of solvable semidefinite programs. It is also complementary to the one developed by de Melo, Cwiklinski and Terhal, which aims at characterizing the set of convex-Gaussian states from the outside. Here we present an explicit proof that criterion by de Melo et al. is complete, by estimating a distance between an n-extendible state, a state that passes the criterion, to the set of convex-Gaussian states.
Bilingualism is always cognitively advantageous, but this doesn’t mean what you think it means

description: For decades now a research question has firmly established itself as a staple of psychological and neuroscientific investigations on language, namely the question of whether and how bilingualism is cognitively beneficial, detrimental or neutral. As more and more studies appear every year, it seems as though the research question itself is firmly grounded and can be answered if only we use the right experimental manipulations and subject the data to the right analysis methods and interpretive lens. In this paper we propose that, rather than merely improving prior methods in the pursuit of evidence in one direction or another, we would do well to carefully consider whether the research question itself is as firmly grounded as it might appear to be. We identify two bodies of research that suggest the research question to be highly problematic. In particular, drawing from work in sociolinguistics and in embodied cognitive science, we argue that the research question of whether bilingualism is cognitively advantageous or not is based on problematic assumptions about language and cognition. Once these assumptions are addressed head on, a straightforward answer to the question arises, but the question itself comes to seem to be a poor starting point for research. After examining why this is so, we conclude by exploring some implications for future research.
Connector Architecture for Indexing Heterogenous Data Sources
Creators: name: Jankowski, Dennis
Publisher: name: Zenodo
Year: 2022

description: More and more applications today rely on the use of many different data sources simultaneously. Often, the data needed for the individual applications already exists, but the potential data consumers cannot find the data because it is distributed across a wide range of data provider infrastructures. Unlike classic web data with https, data and streams can be provided in a wide variety of ways, such as in databases, via rest interfaces or FTP servers. Simple indexing and searching is therefore not possible on the data. Therefore, in this presentation we present a connector-based approach that abstracts the level of technical heterogeneity of data sources and thus makes it generally possible to index and search data sources in a unified way.

description: The behaviour in simple shear of two concentrated and strongly cohesive mineral suspensions showing highly non-monotonic flow curves is described. Two rheometric test modes were employed, controlled stress and controlled shear-rate. In controlled stress mode the materials showed runaway flow above a yield stress, which, for one of the suspensions, varied substantially in value and seemingly at random from one run to the next, such that the up flow-curve appeared to be quite irreproducible. The down-curve was not though, as neither was the curve obtained in controlled rate mode, which turned out to be triple-valued in the region where runaway flow was seen in controlled rising stress. For this first suspension, the total stress could be decomposed into three parts to a good approximation: a viscous component proportional to a plastic viscosity, a constant isostatic contribution, and a third shear-rate dependent contribution associated with the particulate network which decreased with increasing shear-rate raised to the -7/10th power. In the case of the second suspension, the stress could be decomposed along similar lines, although the strain-rate softening of the solid-phase stress was found to be logarithmic and the irreducible isostatic stress was small. The flow curves are discussed in the light of recent simulations and they conform to a very simple but general rule for non-monotonic behaviour in cohesive suspensions and emulsions, namely that it is caused by strain-rate softening of the solid phase stress.

description: In recent years, many academic and technical discussions about cities have been shaped by two topics: sustainability and smartness. While these two areas are evolving, there are definitely common grounds to be found in discourses on sustainability and smartness. First of all, this is the realization that any comprehensive transformation of long-term, complex processes requires governance and integration of topics and institutions, and second, that there can be no uniform approach to successfully becoming more sustainable or smarter. However, different directions of development can be identified that may—or may not—go together. Urban mobility has to deal with different definitions of and approaches to sustainability and smartness too. A specific format developed during the transdisciplinary project “Neue Mobilität Berlin” (New Mobility Berlin, http://neue-mobilitaet.berlin/) addresses these questions. Research results suggest, for one, that there are very practical technical issues that complicate a transition from existing mobility systems toward more sustainable and smart ones. For another, the results suggest that a comprehensive sustainable and smart urban mobility system will need more integration and coordination. This contribution takes off from project findings and discusses implications for the implementations of and discourses on smart and sustainable urban mobility.

description: Only glazing assemblies with tempered or heat-strengthened glass are considered here. Such glass has only minimal passive fire protection. But when a dedicated automatic sprinkler system applies a film of water on it, it remains intact for more than an hour, provided the sprinkler is triggered before the temperature at which such glass breaks is reached. Sprinklers can be mounted at the top of a window or to the ceiling close to a window. Their proper placement required many considerations in the research, among them mullion depth and window width. Even more with multiple-sprinkler systems.

Mais lorsqu'un système spécialisé de protection par gicleur projette un film d'eau sur ce vitrage, celui-ci peut rester intact pendant plus d'une heure à condition que le gicleur se déclenche avant que ne soit atteinte la température à laquelle ce type de verre se brise. Le gicleur peut être monté en haut de la fenêtre ou au plafond, près de celle-ci. Pour déterminer l'emplacement idéal du ou des gicleurs, les chercheurs ont tenu compte de plusieurs facteurs, dont l'épaisseur du meneau et la largeur de la fenêtre, - et d'autres encore dans le cas des systèmes multigicleurs.

description: We investigate the topological change of a Belavin-Polyakov skyrmion under the action of a spin-polarized current. The dynamics is described by the Schrödinger equation for the electrons carrying the current coupled to the Landau-Lifshitz equation for the evolution of the magnetic texture in a square lattice. We show that the addition of an exchange dissipation term, tends to smooth the transition from the skyrmion state to the ferromagnetic state. We demonstrate that this topological change, in the continuum dissipationless limit, can be described as a self-similar finite-time singularity by which the skyrmion core collapses.

description: The Industry 4.0 (I4.0) concept revolutionizes how processes like quality, productivity, customization, and safety are managed in manufacturing. It has developed alongside 5G technology, and the two influence each other significantly. 5G supports the communication needs of I4.0, while I4.0 is a major sector for 5G growth. This whitepaper offers a comprehensive view of I4.0 design principles, driven by collaboration between I4.0 leaders and contributors to 5G development. It also assesses the applicability of 5G for short and mid-term I4.0 challenges based on input from stakeholders. The report touches on evolving 5G technologies, like Deterministic Networking and Digital Twining, and explores the future of ecosystem dynamics, regulation, and sustainability. Ultimately, it provides valuable insights into the synergy between I4.0 and 5G, drawing from leading 5G-PPP Phase III projects.
Is Compton cooling sufficient to explain evolution of observed quasi-periodic oscillations in Outburst sources?

description: In outburst sources, quasi-periodic oscillation (QPO) frequency is known to evolve in a certain way: in the rising phase, it monotonically goes up till a soft intermediate state is achieved. In the propagating oscillatory shock model, oscillation of the Compton cloud is thought to cause QPOs. Thus, in order to increase QPO frequency, Compton cloud must collapse steadily in the rising phase. In decline phases, exactly opposite should be true. We investigate cause of this evolution of the Compton cloud. The same viscosity parameter which increases the Keplerian disk rate, also moves the inner edge of the Keplerian component, thereby reducing the size of the Compton cloud and reducing the cooling time scale. We show that cooling of the Compton cloud by inverse Comptonization is enough for it to collapse sufficiently so as to explain the QPO evolution. In the Two Component Advective Flow (TCAF) configuration of Chakrabarti-Titarchuk, centrifugal force induced shock represents boundary of the Compton cloud. We take the rising phase of 2010 outburst of Galactic black hole candidate H~1743-322 and find an estimation of variation of $α$ parameter of the sub-Keplerian flow to be monotonically rising from $0.0001$ to $0.02$, well within the range suggested by magneto-rotational instability. We also estimate the inward velocity of the Compton cloud to be a few meters/second which is comparable to what is found in several earlier studies of our group by empirically fitting the shock locations with the time of observations.

Изучаются методы повышения полевой всхожести семян, ускорение всхожести семян, влияние внешних факторов на всхожесть семян, использование биодобавок и физических методов. Немалую роль играет магнитное поле в увеличении всхожести семян. Доказано, что при дополнительном облучении магнитным полем семена растений прорастают более активно – длина проростков облученных семян больше чем на 20% длины проростков необлученных семян. В данной статье мы рассматриваем влияние и переменного, и постоянного магнитного поля на всхожесть семян. В отличие от иных статей, где рассматривается точечное влияние магнитного поля, мы использовали несколько
источников магнитного поля (сильные магниты) и заданные параметры поля, чтобы найти оптимальный вариант для увеличения всхожести растений.

description: Recovering and reconstructing networks by accurately identifying missing and unreliable links is a vital task in the domain of network analysis and mining. In this article, by studying a specific local structure, namely a degree block having a node and its all immediate neighbors, we find it contains important statistical features of link formation for complex networks. We therefore propose a parameter-free local blocking (LB) predictor to quantitatively detect link formation in given networks via local link density calculations. The promising experimental results performed on six real-world networks suggest that the new index can outperform other traditional local similarity-based methods on most of tested networks. After further analyzing the scores' correlations between LB and two other methods, we find that the features of LB index are analogous to those of both PA index and short-path-based index, which empirically verify that large degree principle and short path principle simultaneously captured by the LB index are jointly driving link formation in complex networks.

description: We develop a formalism to describe the discrete-time dynamics of systems containing an arbitrary number of interacting species. The individual-based model, which forms our starting point, is described by a Markov chain, which in the limit of large system sizes is shown to be very well-approximated by a Fokker-Planck-like equation, or equivalently by a set of stochastic difference equations. This formalism is applied to the specific case of two species: one predator species and its prey species. Quasi-cycles --- stochastic cycles sustained and amplified by the demographic noise --- previously found in continuous-time predator-prey models are shown to exist, and their behavior predicted from a linear noise analysis is shown to be in very good agreement with simulations. The effects of the noise on other attractors in the corresponding deterministic map, such as periodic cycles, quasiperiodicity and chaos, are also investigated.

They come in two types: latex emulsions and epoxies, each with its particular advantages in given situations. Epoxy bonding agents are good for making sure that freshly placed concrete sticks to cured concrete. Latex bonding agents give, for example, stability where calcium ions abound. Thank goodness for a bonding agent suitable for overhead cement repairs.

Les produits de liaison à la résine époxy permettent de faire en sorte que le béton frais adhère au béton durci. Les produits de liaison en émulsions sont, par exemple, un gage de stabilité lorsque les ions calcium abondent.

description: Disparities in Mathematics performance have been shown across race and gender for decades, although little research has reported the race by gender nexus in terms of disparity. In turn, research done to ameliorate these disparities have assumed that these differences are primarily among student populations who need remedial learning improvement. In this research, we test these assumptions by using multinomial regression analyses and adjusted mean comparisons with bias-corrected effect sizes from a data set of ~20,000 2nd grade students in Chicago. Further, we contribute to previous elementary Mathematics research by illuminating the powerful impacts that spatial reasoning integrations into Mathematics curriculum and pedagogy can have for all students' learning. Our findings provide empirical support that even after accounting for the effects of school composition, racial disparities exist in the beginning and persist throughout the year, among 2nd grade students. However, upon disaggregating students by race, gender, and median split, such disparities are greatest among students that are above the median. Our results encourage quantitative research analyses that explore ways to reduce Mathematics disparities to sharpen their approaches to be more sensitive to the achievement levels of students among such equity inquiries.

description: When masonry walls were thick and the materials used quite porous, their very mass absorbed the rainwater and later released it. Eventually, though, walls became thinner and something had to be done to prevent rain penetration. That could be either a face-sealed wall, which in a sense is a rainwater barrier in the form of vinyl or aluminum cladding on the outside wall, or a cavity wall, which consists of one wall just to catch the rain and an adjacent cavity to serve as moisture break. With open rainscreen walls, which reflect current thinking in wall construction, the cladding constitutes the first line of defence. And then there is a second line of defence.

Puis, l'épaisseur des murs diminua et il a fallu prendre des mesures pour empêcher la pénétration de l'eau de pluie. On avait le choix entre un mur à surface étanche, qui constitue une barrière contre l'eau de pluie, sous la forme d'un revêtement de vinyle ou d'aluminium placé sur le mur extérieur, ou un mur avec lame d'air, c'est-à-dire un mur qui reçoit l'eau de pluie et une lame d'air adjacente permettant de retenir l'humidité. Avec des écrans pare-pluie, concept actuel des constructions modernes, le revêtement constitue le premier niveau de protection, la lame d'air, le second.

description: During the last two decades density functional based linear response approaches have become the de facto standard for the calculation of optical properties of small and medium-sized molecules. At the heart of these methods is the solution of an eigenvalue equation in the space of single-orbital transitions, whose quickly increasing number makes such calculations costly if not infeasible for larger molecules. This is especially true for time-dependent density functional tight binding (TD-DFTB), where the evaluation of the matrix elements is inexpensive. For the relatively large systems that can be studied the solution of the eigenvalue equation therefore determines the cost of the calculation. We propose to do an oscillator strength based truncation of the single-orbital transition space to reduce the computational effort of TD-DFTB based absorption spectra calculations. We show that even a sizeable truncation does not destroy the principal features of the absorption spectrum, while naturally avoiding the unnecessary calculation of excitations with small oscillator strengths. We argue that the reduced computational cost of intensity-selected TD-DFTB together with its ease of use compared to other methods lowers the barrier of performing optical properties calculations of large molecules, and can serve to make such calculations possible in a wider array of applications.

description: The edge currents of two dimensional topological chiral superconductors with nonzero Cooper pair angular momentum---e.g., chiral $p$-, $d$-, and $f$-wave superconductivity---are studied. Bogoliubov-de Gennes and Ginzburg--Landau calculations are used to show that in the continuum limit, \emph{only} chiral $p$-wave states have a nonzero edge current. Outside this limit, when lattice effects become important, edge currents in non-$p$-wave superconductors are comparatively smaller, but can be nonzero. Using Ginzburg--Landau theory, a simple criterion is derived for when edge currents vanish for non-$p$-wave chiral superconductivity on a lattice. The implications of our results for putative chiral superconductors such as Sr2RuO4 and UPt3 are discussed.

Creators: name: Aghadavood Marnani, Javad
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Breast cancer is a prevalent disease that can be classified into four molecular subtypes based on genetic and molecular markers. This study aimed to develop a machine learning-based approach to classify molecular subtypes of breast cancer using radiomics features extracted from dynamic contrast-enhanced magnetic resonance imaging (DCE MRI). The comprehensive dataset used in this study included 4428 radiomics features per patient, as well as clinical features, making it a valuable resource for future research. Our methodology involved several stages, including image preprocessing, feature extraction, initial and final feature selection, and data cleaning techniques, such as data imputation and Local Outlier Factor (LOF), to ensure the quality of the dataset. We conducted hyperparameter tuning and robustness analysis to optimize the performance of the machine learning algorithms. The results were evaluated in three scenarios: 4-label classification, binary, and 3-label classifications. Our approach achieved up to 85% F1 score in binary classifications and improved the overall accuracy of classifying the four molecular subtypes of breast cancer by 12%, which represents a significant improvement over the original study. These findings suggest that machine learning algorithms can be a powerful tool for improving the diagnosis and treatment of breast cancer, paving the way for personalized medicine approaches. Furthermore, the proposed approach can be applied to other datasets and may be useful in other areas of medical research that rely on radiomics features extracted from medical images.

description: Introduction: Generalized anxiety disorder (GAD) is a chronic uncontrollable excessive anxiety towards a variety of topics. It is one of the most prevalent anxiety diseases, affecting approximately 6% worldwide. Virtual reality (VR) based interventions have received much attention from researchers for the management of mental health problems. This systematic review was conducted to assess the effects of immersive virtual reality techniques and non-immersive techniques in treating patients with GAD. Methods: An extensive systematic literature review was implemented, from inception up to 9 July 2021. Comparative clinical studies that assessed the outcomes of VRT in patients with GAD were included for meta-analysis. Single arm studies were included for systematic review only. Results: A total of six articles with 239 participants with GAD were included in systematic review. The mean age of the included participants ranged from 38.33 to 59.87 years. There was no statistically significant difference between VRT and control groups regarding the anxiety levels (SMD 0.01; 95%CI −0.52, 0.54; P = 0.97), mean depression scores (SMD 1.34; 95%CI −0.80, 3.49; P = 0.22), PSWQ (MD −4.26; 95%CI −10.93, 2.40; P = 0.21), and discomfort status (MD −1.41; 95%CI −3.86, 1.05; P = 0.22). Conclusions: VR improved relatively the manifestations of GAD, reflecting on the patient's quality of life. However, the existing evidence is inconclusive to support the superiority of VR as a substitute for traditional therapies.

description: This thesis focused on memory outcomes in children born very preterm (VP; <32 weeks gestation) and long-term benefits of early intervention for children born VP and their parents. An increased risk of memory difficulties was shown in children born VP throughout childhood, including in working memory (ability to hold and manipulate information), episodic memory (ability to learn and recall information), and prospective memory (ability to carry out pre-planned tasks in the future). Early intervention was found to improve some outcomes in these children up to 13-years, including behaviour, and better motor outcomes in those from families with fewer resources.

description: This study aimed to investigate the roles of a text-highlighting tool and readers’ re-reading behaviour in their integrated understanding of multiple documents. University students (N = 95) read five partly conflicting documents on a health-related issue on a touch display with or without a text-highlighting tool. Integrated understanding of documents was assessed by the number of intertextual connections in essays written after reading and by a source-content mapping task. The provision of the text-highlighting tool resulted in longer initial reading times even when subtracting the time taken for highlighting, but shorter re-reading times, particularly for participants with a high number of re-readings. Further, only for participants with a high number of re-readings, the provision of the text-highlighting tool resulted in more intertextual connections than when no text-highlighting tool was provided. Participants’ source-content integration was positively related to the number of re-readings, regardless of whether the text-highlighting tool was provided. Finally, additional exploratory eye-tracking analyses revealed that for two out of the five documents, participants in the with-highlighting condition focused on significantly smaller parts of the documents during re-reading than controls.
Renormalized entropy of entanglement in relativistic field theory

description: Entanglement is defined between subsystems of a quantum system, and at fixed time two regions of space can be viewed as two subsystems of a relativistic quantum field. The entropy of entanglement between such subsystems is ill-defined unless an ultraviolet cutoff is introduced, but it still diverges in the continuum limit. This behaviour is generic for arbitrary finite-energy states, hence a conceptual tension with the finite entanglement entropy typical of nonrelativistic quantum systems. We introduce a novel approach to explain the transition from infinite to finite entanglement, based on coarse graining the spatial resolution of the detectors measuring the field state. We show that states with a finite number of particles become localized, allowing an identification between a region of space and the nonrelativistic degrees of freedom of the particles therein contained, and that the renormalized entropy of finite-energy states reduces to the entanglement entropy of nonrelativistic quantum mechanics.

description: We examine the role played by viscosity in the excitation of global oscillation modes (both axisymmetric and non-axisymmetric) in accretion discs around black holes using two-dimensional hydrodynamic simulations. The turbulent viscosity is modeled by the $α$-ansatz, with different equations of state. We consider both discs with transonic radial inflows across the innermost stable circular orbit, and stationary discs truncated by a reflecting wall at their inner edge, representing a magnetosphere. In transonic discs, viscosity can excite several types of global oscillation modes. These modes are either axisymmetric with frequencies close to multiples of the maximum radial epicyclic frequency $κ_\mathrm{max}$, non-axisymmetric with frequencies close to multiples of of the innermost stable orbit frequency $Ω_\mathrm{ISCO}$, or hybrid modes whose frequencies are linear combinations of these two frequencies. Small values of the viscosity parameter $α$ primarily produce non-axisymmetric modes, while axisymmetric modes become dominant for large $α$. The excitation of these modes may be related to an instability of the sonic point, at which the radial infall speed is equal to the sound speed of the gas. In discs with a reflective inner boundary, we explore the effect of viscosity on trapped $p$-modes which are intrinsically overstable due to the corotation resonance effect. The effect of viscosity is either to reduce the growth rates of these modes, or to completely suppress them and excite a new class of higher frequency modes. The latter requires that the dynamic viscosity scales positively with the disc surface density, indicating that it is a result of the classic viscous overstability effect.

description: The COVID-19 pandemic has underscored the need for effective ventilation control in public buildings. This study develops and evaluates a smart ventilation control algorithm (SIREN) that dynamically adjusts zone and system-level HVAC operation to maintain an acceptable COVID-19 infection risk and HVAC energy efficiency. SIREN uses real-time building operation data and Trim & Respond control logic to determine zone primary and system outdoor airflow rates. An EnergyPlus and CONTAM co-simulation framework was developed to assess its performance across various control scenarios and US climate zones. Results show that SIREN can flexibly control infection risk within a customized threshold (e.g. 3%) for every zone, while traditional controls cannot. At the building level, SIREN’s HVAC energy consumption is comparable to a fixed 70% outdoor airflow fraction scenario, while its infection risk is lower than the 100% outdoor airflow scenario, illustrating its potential for safe and energy-efficient HVAC operation during pandemics.

description: Only glazing assemblies with tempered or heat-strengthened glass are considered here. Such glass has only minimal passive fire protection. But when a dedicated automatic sprinkler system applies a film of water on it, it remains intact for more than an hour, provided the sprinkler is triggered before the temperature at which such glass breaks is reached. Sprinklers can be mounted at the top of a window or to the ceiling close to a window. Their proper placement required many considerations in the research, among them mullion depth and window width. Even more with multiple-sprinkler systems.
description: Seuls les vitrages en verre trempé ou semi-trempé sont étudiés ici. Ce type de verre n'assure qu'une protection passive minimale contre l'incendie. Mais lorsqu'un système spécialisé de protection par gicleur projette un film d'eau sur ce vitrage, celui-ci peut rester intact pendant plus d'une heure à condition que le gicleur se déclenche avant que ne soit atteinte la température à laquelle ce type de verre se brise. Le gicleur peut être monté en haut de la fenêtre ou au plafond, près de celle-ci. Pour déterminer l'emplacement idéal du ou des gicleurs, les chercheurs ont tenu compte de plusieurs facteurs, dont l'épaisseur du meneau et la largeur de la fenêtre, - et d'autres encore dans le cas des systèmes multigicleurs.

description: Fluorescent lighting arranged in regular arrays of recessed fluorescent lamps, which once passed muster as good, even excellent office lighting, nowadays causes interfering glare on computer screens. (Over the years, people have come to work differently: from paper on horizontal surfaces to vertical computer screens.) The results of an experiment with people working under various lighting conditions in an office reveal that people work more productively and with less eye strain under fluorescent lamps that have an electronic ballast. And more productively yet with certain types of louvers and certain combinations of ambient and task lighting.
description: L'éclairage fluorescent constitué de rangées régulières de luminaires encastrés, considéré autrefois comme un bon, voire un excellent éclairage pour les bureaux, produit aujourd'hui un reflet gênant sur les écrans d'ordinateur (au fil des ans, la façon de travailler a changé : du papier posé à plat sur une surface horizontale, on est passé aux écrans d'ordinateur verticaux). Les résultats d'une expérience faite sur des personnes travaillant dans un bureau dans différentes conditions d'éclairage révèlent que lesdites personnes sont plus productives et ressentent une moins grande fatigue oculaire sous des lampes fluorescentes qui contiennent un ballast électronique. La productivité était encore accrue avec certains types de diffuseurs et certaines associations d'éclairage direct et indirect.

description: Context. Several upcoming helioseismology space missions are very limited in telemetry and will have to perform extensive data compression. This requires the development of new methods of data compression. Aims. We give an overview of the influence of lossy data compression on local helioseismology. We investigate the effects of several lossy compression methods (quantization, JPEG compression, and smoothing and subsampling) on power spectra and time-distance measurements of supergranulation flows at disk center. Methods. We applied different compression methods to tracked and remapped Dopplergrams obtained by the Helioseismic and Magnetic Imager onboard the Solar Dynamics Observatory. We determined the signal-to-noise ratio of the travel times computed from the compressed data as a function of the compression efficiency. Results. The basic helioseismic measurements that we consider are very robust to lossy data compression. Even if only the sign of the velocity is used, time-distance helioseismology is still possible. We achieve the best results by applying JPEG compression on spatially subsampled data. However, our conclusions are only valid for supergranulation flows at disk center and may not be valid for all helioseismology applications.
