Publisher: name: Fraunhofer-Gesellschaft
Year: 2022

description: Autonomous driving needs different sensors to detect person and objects in the near and far field. Radar based sensors are a good candidate because of robustness against different environmental effects like rain. Radar sensors with different transmit and receive antennas allows beamforming. With beamforming and follow up data processing range, angle and distance of persons or objects in relation to the radar sensor can be calculated. Range and velocity can be calculated by FFTs but for the angle an different algorithm is necessary. Often the music and/or adoption of the music algorithm is used to calculate the angle. The FFT can be calculated with mid effort but the music algorithm needs a huge computation power. An efficient implementation for a Tensilica B20 is shown in the presentation and ideas to speed up the algorithm by usage of TIE extensions is also presented.

description: We present a purely gravitational infra-red-calculable production mechanism for dark matter (DM). The source of both the DM relic abundance and the hot Standard Model (SM) plasma is a primordial density of micro black holes (BHs), which evaporate via Hawking emission into both the dark and SM sectors. The mechanism has four qualitatively different regimes depending upon whether the BH evaporation is `fast' or `slow' relative to the initial Hubble rate, and whether the mass of the DM particle is `light' or `heavy' compared to the initial BH temperature. For each of these regimes we calculate the DM yield, $Y$, as a function of the initial state and DM mass and spin. In the `slow' regime $Y$ depends on only the initial BH mass over a wide range of initial conditions, including scenarios where the BHs are a small fraction of the initial energy density. The DM is produced with a highly non-thermal energy spectrum, leading in the `light' DM mass regime ($\sim260\,\mathrm{eV}$ and above depending on DM spin) to a strong constraint from free-streaming, but also possible observational signatures in structure formation in the spin 3/2 and 2 cases. The `heavy' regime ($\sim1.2\times 10^8\,\mathrm{GeV}$ to $M_{\mathrm{Pl}}$ depending on spin) is free of these constraints and provides new possibilities for DM detection. In all cases there is a dark radiation component predicted.

description: The pursuit of understanding parity anomaly in condensed matter systems has led to significant advancements in both theoretical and experimental research in recent years. In this study, we explore the parity anomaly of massless Dirac fermions in a semimagnetic topological insulator (TI) thin film subjected to a finite magnetic field. Our findings reveal an anomalous half-quantized Hall conductance arising from the occupied electronic states far below the Fermi level, which is directly associated with the parity anomaly. This observation demonstrates a crossover from one-half quantized Hall conductance in a metallic phase at zero field to one or zero quantized Hall conductance in the insulating phase at a strong field in the presence of disorders, serving as a key indicator for confirming parity anomaly. Our work provides valuable insights into the intricate relationship between band topology in condensed matter systems and quantum anomaly in quantum field theory.

description: The São Paolo metallo-β-lactamase-1 (SPM-1) plays an important role in drug resistance of β-lactam antibiotics and bindings of zinc ions produce significant effect on the conformations of SPM-1. Thus, it is of significance for understanding function of SPM-1 to probe the conformational changes of SPM-1 induced by bindings of zinc ions. Because replica-exchange molecular dynamics (REMD) simulations can efficiently improve conformational samplings of proteins, REMD and normal mode analysis (NMA) were performed on three systems, including SPM-1 with non-zinc ions, single zinc ion and double zinc ions, to decipher molecular mechanism of conformational changes for SPM-1. The results suggest that binding of double zinc ions induces a closed state of SPM-1, while SPM-1 with binding of non-zinc and single zinc ion mainly exists as an open conformation. The analysis of interaction network between residues was carried out by using the program Ring 2.0. The results show that binding of double zinc ions highly enhances the stability of the π-π interaction network consisting of F60, Y61, F82, F152, Y153 and Y226, two hydrogen bonds between E83 and R161 as well as the salt bridge interaction between E151 and K159 compared to the SPM-1 with non-zinc or single zinc ion, which better stabilizes the closed conformation of SPM-1. Thus, the closed conformation of SPM-1 induced by bindings of double zinc ions is important in catalysis and determining inhibitor selectivity. Meanwhile, this work may provide useful theoretical hints for design of potent inhibitors toward drug resistance of β-lactam antibiotics.

description: Focusing on two commonly used indicators of turnout, VAP turnout (the number of votes cast as a percentage of the population of voting age) and RV turnout (votes cast as a percentage of the number of registered voters), this article discusses possible biases induced by migration flows. Using a global dataset on elections in over 100 democracies between 1990 and 2012, we test the potential bias induced by the percentage of resident non-citizens and nationals living abroad on VAP and RV turnout, respectively. Through time series cross sectional analysis, we find that the number of resident non-citizens does negatively bias VAP turnout, to the extent that a country with 10 percent non-citizen residents would have turnout underreported by nearly 4 percentage points. In contrast, we find that the number of nationals living abroad does not induce a turnout bias.

description: This paper considers the effect of least squares procedures for nearly unstable linear time series with strongly dependent innovations. Under a general framework and appropriate scaling, it is shown that ordinary least squares procedures converge to functionals of fractional Ornstein--Uhlenbeck processes. We use fractional integrated noise as an example to illustrate the important ideas. In this case, the functionals bear only formal analogy to those in the classical framework with uncorrelated innovations, with Wiener processes being replaced by fractional Brownian motions. It is also shown that limit theorems for the functionals involve nonstandard scaling and nonstandard limiting distributions. Results of this paper shed light on the asymptotic behavior of nearly unstable long-memory processes.

Running Head: ABORTION CARE IN HUMANITARIAN CONFLICTS Abortion Care in Humanitarian Conflict-Affected Settings: A Scoping Review
Creators: name: Pabalan, Camille
Publisher: name: My University
Year: 2019

description: This major research paper seeks to examine the literature on safe abortion care within humanitarian conflict settings. In the last decade, there has been a growing discussion within the humanitarian community recognizing the importance of providing safe abortion care. Unsafe abortion is one of the leading causes of maternal mortality, a risk that is particularly heightened for pregnant women in humanitarian conflict settings. In such challenging contexts, access to reproductive health services is often limited. This, in addition to the increasingly protracted nature of humanitarian conflicts, means that many girls often reach reproductive age without key reproductive health services, such as contraception, during a situation of conflict and/or displacement. With the systematic use of rape and sexual violence as weapons of war, girls in humanitarian conflicts are more exposed to unintended pregnancy outcomes, which increases the risk of self-aborting through unsafe methods. Through a scoping review methodology, this major research paper seeks to provide a preliminary mapping of the key issues identified in the literature on abortion care within humanitarian conflicts. This paper examines the global discussions to make safe abortion care a priority within humanitarian settings; outlines the numerous challenges – legal, operational, cultural, and political – that humanitarian organizations face in providing this health service; and ultimately provides a way forward for future studies that seek to delve deeper into this topic.

description: Can a single, universal speech interface look-and-feel be used to effectively control a wide variety of appliances? Can such an interface be automatically derived from a functional appliance specification? We built the Speech Graffiti Personal Universal Controller (SG-PUC), a universal interface and framework for human-appliance speech interaction, as a proof-of-concept. Its specification language and communications protocol effectively separate the SG-PUC from the appliances that it controls, enabling mobile and universal speech-based appliance control. To realize such an automatically derived dialog system, the controller employs a universal control language. The development of interfaces to numerous appliances and the results of user studies demonstrate the usefulness of the SG-PUC, indicating that high quality and low cost human-appliance speech interface can be largely appliance agnostic. This investigation also helps to validate the principles of Speech Graffiti as a speech interface paradigm, and provides a baseline for future studies in this area.

description: En los últimos años el derecho a la manifestación pública ha tenido un gran auge, pues, la ciudadanía ha entendido que a través de su ejercicio se pueden alcanzar derechos y evitar la materialización de políticas públicas, que a su juicio pueden resultar perjudiciales. Sin embargo, ejercer este derecho ha propiciado que algunas manifestaciones públicas se tornen violentas o se desvíen de su objetivo principal, ahí, las fuerzas del estado, como Policía o Ejercito Nacional deben actuar para controlar el escenario, ello ha generado, en ocasiones, daños por el uso excesivo de la fuerza, o también, daños a terceros que no participan en la manifestación al no actuar protegiendo su integridad y bienes. En ese contexto, mediante este trabajo se ha realizado un recuento de la normatividad que regula este derecho, un estudio a los elementos generales de la responsabilidad extracontractual en Colombia y, a partir de esto, un análisis de línea jurisprudencial a fin de determinar si existe responsabilidad del estado por esos daños que se ocasionan en manifestaciones públicas, determinando cómo el Consejo de Estado ha abordado esos elementos de la responsabilidad extracontractual en estos eventos, puntualizando si existe o no unanimidad en los fundamentos que se aplican.
description: In recent years, the right to public demonstration has experienced a significant growth, as citizens have come to understand that exercising this right can lead to the achievement of their rights and the prevention of the implementation of public policies that they deem harmful. However, exercising this right has led to some public demonstrations becoming violent or deviating from their primary objective. In such cases, state forces, such as the Police or National Army, must act to control the situation. This has, at times, resulted in damages due to the excessive use of force, or even damages to third parties who do not participate in the demonstration by failing to protect their integrity and property. In this context, this work provides an overview of the regulations that govern this right, a study of the general elements of non-contractual liability in Colombia, and an analysis of the jurisprudential line in order to determine whether the state is liable for damages caused during public demonstrations. The work examines how the Council of State has addressed these elements of non-contractual liability in these events, and whether there is unanimity in the grounds that are applied.

description: In this letter we continue the calculation of master integrals for massless three-loop form factors by giving analytical results for those integrals which are relevant for the fermionic contributions proportional to N_F^2, N_F*N, and N_F/N. Working in dimensional regularisation, we express one of the integrals in a closed form which is exact to all orders in epsilon, containing Gamma-functions and hypergeometric functions of unit argument. In all other cases we derive multiple Mellin-Barnes representations from which the coefficients of the Laurent expansion in epsilon are extracted in an analytical form. To obtain the finite part of the three-loop quark and gluon form factors, all coefficients through transcendentality six in the Riemann zeta-function have to be included.

description: We calculate the matching, at leading order, of the transverse momentum-dependent fragmentation functions (TMDFFs) for light quarks and gluons fragmenting to a $J/ψ$ onto polarized nonrelativistic QCD (NRQCD) TMDFFs. The NRQCD TMDFFs have an operator-product-expansion in terms of nonperturbative NRQCD production matrix elements. Using the results we obtain, we make predictions for the light quark fragmentation contribution to the production of polarized $J/ψ$ in semi-inclusive deep inelastic scattering (SIDIS) both for unpolarized and longitudinally polarized beams. These results are an important contribution to polarized $J/ψ$ production in SIDIS, and thus are needed for comparison with experiments at the future Electron-Ion Collider.

description: Malware detectors based on deep learning (DL) have been shown to be susceptible to malware examples that have been deliberately manipulated in order to evade detection, a.k.a. adversarial malware examples. More specifically, it has been show that deep learning detectors are vulnerable to small changes on the input file. Given this vulnerability of deep learning detectors, we propose a practical defense against adversarial malware examples inspired by randomized smoothing. In our work, instead of employing Gaussian or Laplace noise when randomizing inputs, we propose a randomized ablation-based smoothing scheme that ablates a percentage of the bytes within an executable. During training, our randomized ablation-based smoothing scheme trains a base classifier based on ablated versions of the executable files. At test time, the final classification for a given input executable is taken as the class most commonly predicted by the classifier on a set of ablated versions of the original executable. To demonstrate the suitability of our approach we have empirically evaluated the proposed ablation-based model against various state-of-the-art evasion attacks on the BODMAS dataset. Results show greater robustness and generalization capabilities to adversarial malware examples in comparison to a non-smoothed classifier.

description: Direct numerical simulations of closely interacting infinite circular cylinders in a Bingham fluid are presented, and results compared to asymptotic solutions based on lubrication theory in the gap. Unlike for a Newtonian fluid, the macroscopic flow outside of the gap between the cylinders is shown to have a large effect on the pressure profile within the gap and the resulting lubrication force on the cylinders. The presented results indicate that the asymptotic lubrication solution can be used to predict the lubrication pressure only if the surrounding viscoplastic matrix is yielded by a macroscopic flow. This has implications for the use of sub-grid-scale lubrication models in simulations of non-colloidal particulate suspensions in viscoplastic fluids.

description: Numerous audio systems for musicians are expensive and bulky. Therefore, it could be advantageous to model them and to replace them by computer emulation. In guitar players’ world, audio systems could have a desirable nonlinear behavior (distortion effects). It is thus difficult to find a simple model to emulate them in real time. Volterra series model and its subclass are usual ways to model nonlinear systems. Unfortunately, these systems are difficult to identify in an analytic way. In this paper we propose to take advantage of the new progress made in neural networks to emulate them in real time. We show that an accurate emulation can be reached with less than 1% of root mean square error between the signal coming from a tube amplifier and the output of the neural network. Moreover, the research has been extended to model the Gain parameter of the amplifier.

description: L’homicide intrafamilial constitue un problème qui secoue l’ensemble de la société lorsqu’il se produit. Ce phénomène est complexe, car plusieurs facteurs menant à ces homicides interagissent et l’issue de situations à risque est souvent imprévisible. Beaucoup d’études portent sur les caractéristiques des auteur.e.s et des victimes, des contextes et d’autres facteurs entourant ces homicides, souvent dans le but de mieux les comprendre et d’arriver à les prévenir. Bien que fragmentaires, quelques dénominateurs communs s’en dégagent et des outils d’évaluation des situations à risque ont vu le jour. Par ailleurs, les connaissances sur le sujet ont indiqué que le partage d’informations entre organismes et professionnels sur des situations potentiellement létales constitue une pratique à développer afin d’agir sur ces situations. Le Code des professions québécois s’est adapté à cette réalité, en permettant plus facilement la levée de la confidentialité lorsque des indicateurs de passage à l’acte sont présents. Dans la foulée de ces changements, des protocoles d’intervention se sont développés entre acteurs issus des services sociaux, policiers et judiciaires dans certaines régions québécoises afin d’intervenir rapidement sur ces situations. Cette recherche vise à documenter le fonctionnement d’un de ces protocoles d’intervention. Des entrevues semi-dirigées ont été réalisées auprès de 10 membres du protocole d’intervention A-GIR, à Laval afin de recueillir leurs perceptions sur plusieurs aspects : le fonctionnement, les outils d’analyse du risque homicide, la confidentialité, les formations, le financement, les difficultés et enjeux, les éléments-clés nécessaires à l’implantation d’une nouvelle cellule, les conditions favorables au fonctionnement et à la pérennité du protocole, et en dernier les recommandations des participant.e.s afin de d’améliorer le protocole. Analysés à l’aide d’un cadre théorique constitué d’indicateurs de la qualité de partenariat, les résultats indiquent que les participant.e.s sont unanimes sur l’importance de la concertation qui se traduit par la qualité des liens et du niveau de confiance entre les partenaires. Également, il est démontré que même si l’engagement des partenaires au sein d’un tel protocole est exigeant, il constitue un moyen d’intervention qui a fait ses preuves et qui mérite d’être implanté à plus grande échelle. Mots clés : prévention de l’homicide conjugal, évaluation d’un protocole d’intervention, intersectorialité, A-GIR, cellule de crise, concertation, partenariat.

description: Wer einmal die Aufgabe hatte, Erstsemester in das wissenschaftliche Arbeiten einzuführen und deren Kenntnisse mit Hilfe einer Klausur zu überprüfen, weiß um die Schwierigkeit dieses Vorhabens. An der Hochschule Hof wurde deshalb im Studiengang Betriebswirtschaft / Betriebswirtschaft dual eine neue Veranstaltungsform entwickelt, die die zu vermittelnden Kompetenzen durch aktives Lernen aufbaut und passend durch das betreute Erstellen einer Hausarbeit zu einem Themengebiet der möglichen Studienschwerpunkte prüft. Dies geschieht gewissermaßen als „Probelauf“ zur Bachelorarbeit; die Evaluationen durch die Studierenden und die Erfahrungen der Betreuer von Abschlussarbeiten sind positiv. Die Veranstaltung ist bereits seit dem Wintersemester 2016 in der SPO verankert und wird von mehreren Kollegen durchgeführt. Neben dem allgemeinen Rahmen, der durch das Modulhandbuch umrissen wird, werden konkrete Didaktik-Beispiele und positive wie negative Erfahrungen dargestellt.

description: Diabetic retinopathy is a severe complication of diabetes that can lead to permanent blindness if not treated promptly. Early and accurate diagnosis of the disease is essential for successful treatment. This paper introduces a deep learning method for the detection and stage grading of diabetic retinopathy, using a single fundus retinal image. Our model utilizes transfer learning, employing two state-of-the-art pre-trained models as feature extractors and fine-tuning them on a new dataset. The proposed model is trained on a large multi-center dataset, including the APTOS 2019 dataset, obtained from publicly available sources. It achieves remarkable performance in diabetic retinopathy detection and stage classification on the APTOS 2019, outperforming the established literature. For binary classification, the proposed approach achieves an accuracy of 98.50, a sensitivity of 99.46, and a specificity of 97.51. In stage grading, it achieves a quadratic weighted kappa of 93.00, an accuracy of 89.60, a sensitivity of 89.60, and a specificity of 97.72. The proposed approach serves as a reliable screening and stage grading tool for diabetic retinopathy, offering significant potential to enhance clinical decision-making and patient care.

Geometric rectification for nanoscale vibrational energy harvesting

description: In this work, we present a mechanism that, based on quantum-mechanical principles, allows one to recover kinetic energy at the nanoscale. Our premise is that very small mechanical excitations, such as those arising from sound waves propagating through a nanoscale system or similar phenomena, can be quite generally converted into useful electrical work by applying the same principles behind conventional adiabatic quantum pumping. The proposal is potentially useful for nanoscale vibrational energy harvesting where it can have several advantages. The most important one is that it avoids the use of classical rectification mechanisms as it is based on what we call geometric rectification. We show that this geometric rectification results from applying appropriate but quite general initial conditions to damped harmonic systems coupled to electronic reservoirs. We analyze an analytically solvable example consisting of a wire suspended over permanent charges where we find the condition for maximizing the pumped charge. We also studied the effects of coupling the system to a capacitor including the effect of current-induced forces and analyzing the steady-state voltage of operation. Finally, we show how quantum effects can be used to boost the performance of the proposed device.

description: Despite significant progress in Text-to-Image (T2I) generative models, even lengthy and complex text descriptions still struggle to convey detailed controls. In contrast, Layout-to-Image (L2I) generation, aiming to generate realistic and complex scene images from user-specified layouts, has risen to prominence. However, existing methods transform layout information into tokens or RGB images for conditional control in the generative process, leading to insufficient spatial and semantic controllability of individual instances. To address these limitations, we propose a novel Spatial-Semantic Map Guided (SSMG) diffusion model that adopts the feature map, derived from the layout, as guidance. Owing to rich spatial and semantic information encapsulated in well-designed feature maps, SSMG achieves superior generation quality with sufficient spatial and semantic controllability compared to previous works. Additionally, we propose the Relation-Sensitive Attention (RSA) and Location-Sensitive Attention (LSA) mechanisms. The former aims to model the relationships among multiple objects within scenes while the latter is designed to heighten the model's sensitivity to the spatial information embedded in the guidance. Extensive experiments demonstrate that SSMG achieves highly promising results, setting a new state-of-the-art across a range of metrics encompassing fidelity, diversity, and controllability.

What Factors Affect Canadian Overnight Trips from 2006 to 2016?
Creators: name: Han, Yan
Publisher: name: My University
Year: 2019

description: With data obtained from Statistics Canada, this paper analyzes what factors affect the number of overnight trips from 2006 to 2016. The monthly data in the same years are pooled, and the annual data before and after 2011 are pooled into two large datasets. The results show that Canadians like to travel in summer and those with higher educational attainments and household incomes tend to travel more than others. The increasing number of household members has a negative relationship with the number of trips. Interestingly, Torontonians travel the least among the residents of all metropolitan areas, and residents from the prairie provinces travel more than others. The explanatory power of my model in different periods is around 6% or 7%, so the number of overnight trips may mainly depend on people’s different preferences.

description: In this paper we perform an amplitude analysis of $η'\toπ^+π^-γ$ and confront it with the latest BESIII data. Based on the final-state interaction theorem, we represent the amplitude in terms of an Omnés function multiplied by a form factor that corresponds to the contributions from left-hand cuts and right-hand cuts in the inelastic channels. We also take into account the isospin violation effect induced by $ρ-ω$ mixing. Our results show that the anomaly contribution is mandatory in order to explain the data. Its contribution to the decay width of $Γ(η'\toππγ)$ is larger than that induced by isospin violation. Finally we extract the pole positions of the $ρ$ and $ω$ as well as their corresponding residues.
