description: In this paper we present a theoretical performance analysis of the maximum ratio combining (MRC) rule for channel-aware decision fusion over multiple-input multiple-output (MIMO) channels for (conditionally) dependent and independent local decisions. The system probabilities of false alarm and detection conditioned on the channel realization are derived in closed form and an approximated threshold choice is given. Furthermore, the channel-averaged (CA) performances are evaluated in terms of the CA system probabilities of false alarm and detection and the area under the receiver operating characteristic (ROC) through the closed form of the conditional moment generating function (MGF) of the MRC statistic, along with Gauss-Chebyshev (GC) quadrature rules. Furthermore, we derive the deflection coefficients in closed form, which are used for sensor threshold design. Finally, all the results are confirmed through Monte Carlo simulations.

description: In this paper, a new Lagrangian cloud model (LCM) is introduced in which the flow field is simulated by large-eddy simulation, and the droplets are treated as Lagrangian particles responding to the simulated flow field. In order to handle the extremely large number of droplets within a cloud, the concept of a super-droplet, which represents a large number of real droplets of the same size, is introduced, and the number of contributing real droplets is called the weighting factor. A novel method is developed to realize the collision/coalescence of droplets, in which the consequent variation of the droplet spectrum is represented in terms of the modification of the radius and weighting factor of super-droplets, while keeping the number of super-droplets unchanged. Using an idealized single cloud and trade wind cumuli, the LCM is shown to reproduce the general features of shallow cumulus clouds in agreement with traditional bulk models. The droplet spectrum simulated by the LCM, using collision kernels with and without the effects of turbulence, also shows a pattern consistent with the spectral bin model. Furthermore, the sensitivity of the LCM to two model parameters, the time step and the number of super-droplets, is examined.

Experimental data on the interaction of protons with the energies of 0.8 TeV with emulsion nuclei are used. Results do not contradict the formation of relativistic ideal non-viscous liquid in rare central collisions.

title: Internalized weight-bias: psychological correlates and the role of social support among individuals seeking bariatric surgery
Creators: name: Scurrey, Samantha
Publisher: name: Memorial University of Newfoundland
Year: 2022

description: An important factor to consider when examining the increased rates of mental illness among individuals seeking bariatric surgery is internalized weight bias. Internalized weight bias has been observed to be positively associated with depression, anxiety, disordered eating, binge eating, shame and emotional dysregulation, and negatively associated with self-esteem and quality of life. Insufficient attention has been paid towards adverse childhood experiences and socially desirable responding in the extant literature. The aims of the current study were to: 1) examine the associations between internalized weight bias, and symptoms of depression, anxiety, binge eating, self-esteem, adverse childhood experiences, quality of life, and social support; 2) determine which constellation of psychosocial variables account for significant unique variance in internalized weight bias; and 3) investigate whether social support moderates significant associations observed between internalized weight bias, and mental health and quality of life variables examined within the first aim. A total of 119 patients approved to receive bariatric surgery were recruited from bariatric surgery clinics in Calgary, AB and St. John’s, NL. Patients completed questionnaires that measured internalized weight bias, symptoms of depression, anxiety, and binge eating, self-esteem, adverse childhood experiences, impact of weight on quality of life, health-related quality of life, socially desirable responding, and social support while awaiting surgery. Significant bivariate correlations were observed between internalized weight bias and symptoms of depression, anxiety and binge eating, self-esteem, impact of weight on quality of life, and social support, while statistically adjusting for BMI and socially desirable responding. Self-esteem, symptoms of binge eating, social support, and adverse childhood experiences accounted for significant unique variance in internalized weight bias in multiple regression models. Social support did not moderate associations between internalized weight bias and symptoms of depression, anxiety, binge eating, self-esteem, or impact of weight on quality of life. The current study further highlights the importance of internalized weight bias among bariatric surgery populations given its association with mental health and quality of life outcomes, and the need to develop and implement effective interventions.

description: In this paper, we employ the multilevel Monte Carlo finite element method to solve the stochastic Cahn–Hilliard–Cook equation. The Ciarlet–Raviart mixed finite element method is applied to solve the fourth-order equation. In order to estimate the mild solution, we use finite elements for space discretization and the semi-implicit Euler–Maruyama method in time. For the stochastic scheme, we use the multilevel method to decrease the computational cost (compared to the Monte Carlo method). We implement the method to solve three specific numerical examples (both two- and three dimensional) and study the effect of different noise measures. © 2019, The Author(s).

description: Zum Verhältnis Glauben und Wissen gibt es unterschiedliche Annahmen. Von Kampf und Konflikt bis hin zu Symbiose finden sich verschiedene Thesen. Um hier zu begründeteren Einschätzungen zu kommen, wird im ersten Teil am Beispiel konkreter Problemfelder, Waldsterben, Ozonloch, Rinderseuche BSE, das Zusammenspiel von wissenschaftlichen Kenntnissen und geglaubten Werten verfolgt. Durch Länder- und Kulturvergleiche zeigt sich, dass auf der Basis gleichen Wissens unterschiedliche glaubensbezogene politische Schlussfolgerungen gezogen wurden. Das wissenschaftlich eher stiefmütterlich behandelte Phänomen des „Aberglaubens“ wird im zweiten Teil ins Verhältnis zu Wissenschaft und Religion gesetzt. Auf welche Weise entstehen in der Moderne Formen des Aberglaubens, die religiöse und wissenschaftliche Denkfiguren übernehmen. Dies wird am Beispiel der Frage extraterrestrischen Lebens in sogenannten UFO-Gruppen verfolgt.Die im Artikel analysierten Mischungsverhältnisse von Wissen, Glauben und Aberglauben rechtfertigen nicht die kulturrelativistische These einer Nichttrennbarkeit der drei Phänomene – im Gegenteil, sie setzen eine begrifflich und konzeptionell distinkte Bestimmung der Phänomene voraus.

description: We present a leptonic model on the external shock context to describe the high-energy emission of GRB 940217, GRB 941017 and GRB 970217A. We argue that the emission consists of two components, one with a similar duration of the burst, and a second, longer-lasting GeV phase lasting hundred of seconds after the prompt phase. Both components can be described as synchrotron self-Compton emission from a reverse and forward shock respectively. For the reverse shock, we analyze the synchrotron self-Compton in the thick-shell case. The calculated fluxes and break energies are all consistent with the observed values.

description: Ionization by an attosecond pulse launches an electron wave packet in the continuum which contains rich information about the pulse, the parent system, and the ionization dynamics. This emission process is not instantaneous in the sense that the electrons take a finite time to leave the potential. This time is closely related to the Wigner time. In this paper we introduce the stereo Wigner time delay, which measures the relative delay between electrons emitted to the left and right in an asymmetric system. We present a theoretical study of the delay in photoemission for a small asymmetric molecular system using the streaking technique. The stereo Wigner time delay shows advantages compared to previous schemes. Our numerical calculation shows that such a measurement removes the infrared laser-Coulomb coupling, which has been problematic in the interpretation of the measured delay in photoemission from atomic systems. © 2014 American Physical Society.

description: It is commonly believed that organic molecules are physisorbed on the ideal nonpolar surfaces of wide band gap insulators with limited variation in the electronic properties of the adsorbate molecule. On the basis of first principles calculations within density functional theory (DFT) and GW approximation, we show that this is not generally true. We find that the molecular frontier orbitals undergo significant changes when a hydroxy acid (here we chose gluconic acid) is adsorbed on MgSO4 H2 O (100) surface due to the complex interaction between the molecule and the insulating surface. The predicted trend of the adsorption effect on the energy gap obtained by DFT is reversed when the surface polarization effect is taken into account via the many-body corrections. © 2010 American Institute of Physics.

description: Spin polarization of a two-dimensional electron gas with Rashba spin-orbit interaction, induced by a thermo-current, is considered theoretically. It is shown that a temperature gradient gives rise to an in-plane spin polarization of the electron gas, which is normal to the temperature gradient. The low-temperature spin polarization changes sign when the Fermi level crosses bottom edge of the upper electronic subband. We also compare the results with spin polarization induced by an external electric field (current).

description: The susceptibilities of the real and imaginary parts, as well as of the modulus of the Polyakov loop, are computed in SU(3) lattice gauge theory. We show that the ratios of these susceptibilities are excellent probes of the deconfinement transition, independent of the renormalization of the Polyakov loop and only weakly dependent on the system size. The ratios are almost temperature independent above and below the transition and exhibit a discontinuity at the transition temperature. This characteristic behavior can be understood in terms of the global Z(3) symmetry of the Yang-Mills Lagrangian and the general properties of the Polyakov loop probability distribution.

description: Measurements of resonant tunneling through a localized impurity state are used to probe fluctuations in the local density of states of heavily doped GaAs. The measured differential conductance is analyzed in terms of correlation functions with respect to voltage. A qualitative picture based on the scaling theory of Thouless is developed to relate the observed fluctuations to the statistics of single-particle wave functions. In a quantitative theory correlation functions are calculated. By comparing the experimental and theoretical correlation functions, the effective dimensionality of the emitter is analyzed and the dependence of the inelastic lifetime on energy is extracted.

description: Motivated by a recent claim by Muller et al (2010 Nature 463 926-9) that an atom interferometer can serve as an atom clock to measure the gravitational redshift with an unprecedented accuracy, we provide a representation-free description of the Kasevich-Chu interferometer based on operator algebra. We use this framework to show that the operator product determining the number of atoms at the exit ports of the interferometer is a c-number phase factor whose phase is the sum of only two phases: one is due to the acceleration of the phases of the laser pulses and the other one is due to the acceleration of the atom. This formulation brings out most clearly that this interferometer is an accelerometer or a gravimeter. Moreover, we point out that in different representations of quantum mechanics such as the position or the momentum representation the phase shift appears as though it originates from different physical phenomena. Due to this representation dependence conclusions concerning an enhanced accuracy derived in a specific representation are unfounded.

description: In this paper, the design of fuel cells for the main energy supply of passenger transportation aircraft is discussed. Using a physical model of a fuel cell, general design considerations are derived. Considering different possible design objectives, the trade-off between power density and efficiency is discussed. A universal cost-benefit curve is derived to aid the design process. A weight factor wP is introduced, which allows incorporating technical (e.g., system mass and efficiency) as well as non-technical design objectives (e.g., operating cost, emission goals, social acceptance or technology affinity, political factors). The optimal fuel cell design is not determined by the characteristics of the fuel cell alone, but also by the characteristics of the other system components. The fuel cell needs to be designed in the context of the whole energy system. This is demonstrated by combining the fuel cell model with simple and detailed design models of a liquid hydrogen tank. The presented methodology and models allows assessing the potential of fuel cell systems for mass reduction of future passenger aircraft.

description: Understanding the complexities of electronic and magnetic ground states in solids is one of the main goals of solid-state physics. Materials with the canonical ThCr$_2$Si$_2$-type structure have proved particularly fruitful in this regards, as they exhibit a wide range of technologically advantageous physical properties described by "many-body physics," including high-temperature superconductivity and heavy fermion behavior. Here, using high-resolution synchrotron X-ray diffraction and time-of-flight neutron scattering, we show that the isostructural mixed valence compound, KNi$_2$S$_2$, displays a number of highly unusual structural transitions, most notably the presence of charge density wave fluctuations that disappear on cooling. This behavior occurs without magnetic or charge order, in contrast to expectations based on all other known materials. Furthermore, the low-temperature electronic state of KNi$_2$S$_2$ is found to exhibit many characteristics of heavy-fermion behavior, including a heavy electron state ($m^*/m_e \sim$ 24), with a negative coefficient of thermal expansion, and superconductivity below $T_c$ = 0.46(2) K. In the potassium nickel sulfide, these behaviors arise in the absence of localized magnetism, and instead appear to originate in proximity to charge order.

description: In this paper, a new tool concept suitable for simultaneous roughing and finishing operations is presented. The developed end mill has two radial recessed roughing teeth with a flank face chamfer and two sharp finishing teeth. While the chamfered cutting edges ensure a high process stability due to process damping, the sharp cutting edges generate the final surface. In order to investigate the roughing and finishing capabilities, the tool was compared with a roughing tool with chamfered teeth only and a finishing tool with sharp teeth only. With all three tool concepts milling experiments were carried out, in which forces, process stability and surface quality were analyzed. The generated surface quality for the new tool concept could be significantly improved compared to the roughing tool. However, the aimed surface quality of the finishing tool with sharp edges could not be achieved. Moreover, experimental results show that the process stability of the new tool concept is significantly higher than the process stability of the finishing tool.

description: In this systematic survey, an overview of non-conventional actuators particularly used in soft-robotics is presented. The review is performed by using well-defined performance criteria with a direction to identify the exemplary and potential applications. In addition to this, initial guidelines to compare the performance and applicability of these novel actuators are provided. The meta-analysis is restricted to five main types of actuators: shape memory alloys (SMAs), fluidic elastomer actuators (FEAs), shape morphing polymers (SMPs), dielectric electro-activated polymers (DEAPs), and magnetic/electro-magnetic actuators (E/MAs). In exploring and comparing the capabilities of these actuators, the focus was on eight different aspects: compliance, topology-geometry, scalability-complexity, energy efficiency, operation range, modality, controllability, and technological readiness level (TRL). The overview presented here provides a state-of-the-art summary of the advancements and can help researchers to select the most convenient soft actuators using the comprehensive comparison of the suggested quantitative and qualitative criteria.

In the Collaborate Research Center (CRC) 653 smart products, so called “Gentelligent Components”, which collect information about themselves and from their life cycle and store it inherently, are developed. For structuring and standardization of the life cycle information a classification system is used. A classification system for gentelligent components has to consider aspects from the development, manufacturing and usage phases as well as the environment and also the remaining life cycle phase. Therefore different classification systems are compared to their suitability for gentelligent components. Based on the most suitable existing system an approach to describe gentelligent components in their life cycle is developed. The information from development and manufacturing as well as from the usage phase of components life cycle are considered. The resulted classification system is exemplified by a wheel carrier, one of the demonstrator of the CRC 653. The applied classification system shows how gentelligent components and their information can be structured and standardized.

description: Industry 4.0 is the next step to autonomous products, productions and processes, which have the ability to collect information about themselves and their environment and to communicate with each other. The information about the products is analyzed and verified to develop a new product generation, what is called Technical Inheritance. The information about the product are saved in databases, which storage the information but do not structure them. For a unified designation and organization in the development phase Product Data Management (PDM) systems are used. The following paper presents a numbering system, which ensures a unified designation for the Technical Inheritance. Shown on a sorting system for object carriers in a medical environment the numbering system demonstrates, how the Technical Inheritance is implemented and traceable in a PDM system.

description: In this study, we present an adaptive phase field method (APFM) for modeling quasi-static crack propagation in rocks. Crack initiation due to positive strains is considered, and a numerical simulation is implemented using a commercial software, COMSOL Multi-physics. Two benchmark tests are first examined, namely, a single-edge-notched square plate subjected to respective tension and shear loadings. The crack propagation in Brazil splitting tests, 2D notched semi-circular bend (NSCB) tests, and 3D NSCB tests are subsequently simulated and analyzed. All the numerical examples indicate that the propagation of the cracks is autonomous and external fracture criteria are not required for phase field modeling. Furthermore, the adaptive remeshing scheme reduces unnecessary global mesh refinement and exhibits good adaptability for fracture modeling. The simulations are in good agreement with the experimental observations, and thereby indicate the feasibility and practicability of the APFM in rocks (even in 3D cases)

description: Mechanical joining processes provide various advantages over conventional fusion welding of metallic components such as shorter cycle times, little or no heat input and reduced need for subsequent surface finishing operations. Several investigations in the past have shown that joints between tubes and sheets or plates can be manufactured by upsetting operations. Under axial compression, the tube develops a plastic instability in form of bulge. In-between two such bulges, a force and form fit to sheet material can be created. Previous work concentrated on forming fully developed bulges, i.e., at the end of the bulging process, both hinges of the bulge are in contact. This paper presents a numerical and experimental study aiming at optimizing the bulge shape to increase the bearable limit loads. Two new bulge designs are investigated, an 'arrow bulge' and a 'wave bulge'. The paper details the results of FE-simulations of the bulge shapes under bending and torsion loads. Forming tools were designed and both bulge shapes were produced experimentally. The results show that the material flow under compressive plastic instability can be controlled and that the resulting bulge shapes yield improved strength in various load cases.

description: UndocuStudents: Our Untold Stories is a collection of essays, poetry, photographs, and artwork created by members of the Blue Group, an Associated Students Club at Western Washington University, whose mission is to provide undocumented students the opportunity to meet other undocumented students, find resources and services, and to build community.

As the Blue Group has grown from just a few students meeting informally into an official Western Washington University Associated Students club, into an organization that is now widely recognized in their local community, members of the Blue Group increasingly receive requests to give presentations to help people understand their experiences as undocumented immigrants and students.

Undocumented students face a number of pressures and stresses that are unique to their student experience because of their status. This book offers all readers insight and perspective based on the creative outputs originating from some of the undocumented students of Western Washington University.

In writing this book, the Blue Group students offer the readers, be they documented or undocumented immigrants, a way to connect with them and with each other, so that through the sharing of their creative work, they can continue to build community.

In their own words:

“You may read or see a piece in this book that resonates strongly with you, that helps you realize you are not alone. Or you may read or see a piece that causes you to think about something from a new perspective, from a place that challenges you. Or you may read or see something that makes you want to learn even more, something that inspires you to seek out others in your own community whom you can connect with and find ways to support. All of these things are good, and we hope that in sharing these pieces of ourselves, others will feel supported and find ways of giving support.”

description: Auf den Punkt ...
Die Gruppe der hochqualifizierten Beschäftigten gewinnt gegenwärtig in vielen Unternehmen und Branchen an Größe. Viele von ihnen werden als außertarifliche (AT-)Beschäftigte eingestellt. In der chemischen Industrie machen sie bereits 13,3% aller Beschäftigten aus.
Damit nimmt auch die Bedeutung der AT-Beschäftigten für Betriebsräte und Gewerkschaften zu. Da tarifliche Regelungen für AT-Angestellte definitionsgemäß nicht gelten, spielen betriebliche Regulierungen für diese Gruppe die zentrale Rolle.
Aus diesem Grund hat die IG BCE im Rahmen ihrer Zielgruppenarbeit eine AT-spezifische Vorgehensweise entwickelt, die sie den Betriebsräten anbietet. Im Zentrum dieser Vorgehensweise steht die betriebliche Politisierung der AT-Entgelte unter Beteiligung der außertariflichen Angestellten.
Unsere Fallstudien zeigen, dass die Konfliktstrategie der Gewerkschaft in ersten Fällen erfolgreich umgesetzt wurde. Mit ihrer Hilfe konnten die Betriebsräte nicht nur Betriebsvereinbarungen zu den AT-Entgelten durchsetzen, sondern auch die Gewerkschaften und Betriebsräten eher distanziert gegenüberstehenden außertariflichen Beschäftigten aktivieren.
Darüber hinaus haben wir im Rahmen einer Analyse von Betriebsvereinbarungen aus 19 Unternehmen Eckpunkte der Regelung von AT-Entgeltsystemen identifiziert. Es wird deutlich, dass die Definition des AT-Begriffs, das System der Stellenbewertung, das eigentliche Entgeltsystem und der Zusammenhang zwischen diesen bei-den Systemen die Basis für die Funktionsfähigkeit und Qualität der Regelung von AT-Entgelten bilden.

description: Medical ultrasonic arrays are typically characterized in controlled water baths using measurements by a hydrophone, which can be translated with a positioning stage. Characterization of 3D acoustic fields conventionally requires measurements at each spatial location, which is tedious and time-consuming, and may be prohibitive given limitations of experimental setup (e.g., the bath and stage) and measurement equipment (i.e., the hydrophone). Moreover, with the development of new ultrasound sequences and modalities, multiple measurements are often required to characterize each imaging mode to ensure performance and clinical safety. Acoustic holography allows efficient characterization of source transducer fields based on single plane measurements. In this work, we explore the applicability of a re-radiation method based on the Rayleigh–Sommerfeld integral to medical imaging array characterization. We show that source fields can be reconstructed at single crystal level at wavelength resolution, based on far-field measurements. This is herein presented for three practical application scenarios: for identifying faulty transducer elements; for characterizing acoustic safety parameters in focused ultrasound sequences from 2D planar measurements; and for estimating arbitrary focused fields based on calibration from an unfocused sound field and software beamforming. The results experimentally show that the acquired pressure fields closely match those estimated using our technique.
