description:
To clarify the ways in which Black Americans’ experiences of structural racism may influence their mental and physical health in distinct ways, the present study evaluated whether major discrimination moderates the association between depressive symptoms and chronic physical health conditions among this population. t-tests and chi-squared tests of significance were used to determine significant differences between women and men. The association between major discrimination and depressive symptoms was examined by assessing mean depressive symptoms scores across levels of major discrimination. ANOVA tests indicated whether there were significant differences in symptom scores across each discrimination category. Additional t-tests determined significant gender differences within each level of discrimination. Gender-stratified negative binomial models were used, and odds ratios (ORs) and 95% confidence intervals (CIs) were estimated for the relationship between depressive symptoms, major discrimination, and chronic conditions. Our findings indicated that the association between depressive symptoms and chronic conditions depends on lifetime experiences of major discrimination among Black Americans and varies significantly between women and men. Considering that major discrimination conditioned the depressive symptom-chronic conditions association among our sample, this provides insight into potential pathways for intervention in efforts to offset the detrimental mental and physical consequences of experiencing racism.
Planning velocity profiles from task-level constraints and environment uncertainties

Publisher: name: Columbia University
Year: 1993
Subjects: Robotics

description: A method for parameterizing robot trajectories in the presence of uncertainties is presented. The planning process is defined as a problem of constrained optimization and the concept of a task's difficulty is used as an optimization criterion. The task difficulty, as defined by the authors, comprises the combined effects of velocity and uncertainty, mimicking human perception of difficulty in positioning tasks. The success probability is used as a constraint necessary for planning tasks with contradicting requirements. This planning paradigm is demonstrated with an experiment that contains opposing requirements: reaching the obstacle in a given time, but without exceeding certain maximal impact force. The planner is implemented on a real system.

Probability-driven motion planning for mobile robots
Creators: name: Timcenko, Aleksandar
name: Allen, Peter K.
Publisher: name: Columbia University
Year: 1994
Subjects: Robotics

description: This paper proposes a path-planning method for mobile robots in the presence of uncertainty. We analyze environment and control uncertainty and propose methods for incorporating each of them into the planning algorithm. We model the environment using the pyramid structure that encodes the information on occupancy probabilities for each pixel as well as the partial information on conditional probabilities among different pixels. This structure allows for efficient and accurate computation of collision probabilities in the presence of environment uncertainty. The control uncertainty is mainly characterized by its expansion in space and time and is accordingly modeled by a stochastic differential equation that mathematically captures this phenomenon. Models that we develop are inevitably approximate but experiments confirm that they can be used as a reasonable model for motion planning. We have conducted a series of experiments on the mobile platform and some of these results are presented.

description: Fully nonlinear numerical simulation of two dimensional Faraday waves between two incompressible and immiscible fluids is performed by adopting the phase-field method with the Cahn-Hilliard equation due to Jacqmin (1999) [J. Comput. Phys., v.155, 96]. Its validation is checked against the linear theory. In a nonlinear regime, qualitative comparison is made with an earlier vortex-sheet simulation of two dimensional Faraday waves by Wright et al. (2000) [J. Fluid Mech., v.400, 1]. The vorticity outside the interface region is studied in this comparison. The period tripling state, which is observed in the quasi-two dimensional experiment by Jiang et al. (1998) [J. Fluid Mech., v.369, 273], is successfully simulated with the present phase-field method.

description: Ziel dieser Arbeit ist es, das thermische Laserstrahlseparieren zu evaluieren, Limits aufzuzeigen und Grenzen zu erweitern. Hierbei wurden die Anwendungsfälle Chipvereinzelung und photovoltaische Halbzellenproduktion getrennt voneinander untersucht. Besonderes Augenmerk liegt auf der Reduktion von möglichen Rissabweichungen und einer Verbesserung der Prozessgenauigkeit. Zur Erreichung dieser Genauigkeitsverbesserung wurde ein simulativer Ansatz gewählt. Nach einer Manipulation der verschiedenen Parameter innerhalb der FEM-Simulation, konnten diese auf die Realität übertragen und experimentell überprüft werden. Dies erlaubte die Validierung der Erkenntnisse. Durch dieses systematische Vorgehen konnten die Rissabweichung an der Waferkante um den Faktor 10 reduziert werden.
description: The aim of this work is to evaluate the thermal laser separation while having a focused look on the process limits and the extension of these. Two different use cases were investigated. First the conventional wafer dicing and second the photovoltaics half cell production. Especially the crack deviations and the total process accuracy were investigated. To improve the accuracy, a FEM simulation was developed. Thus, the parameters could be varied and transferred into the reality afterwards. Due to this procedure the simulation model could be validated. All in all, a reduction of the crack deviation next to the wafer edge by the factor of ten has been achieved.
Active, uncalibrated visual servoing

Subjects: Robotics

description: Proposes a method for visual control of a robotic system which does not require the formulation of an explicit calibration between image space and the world coordinate system. Calibration is known to be a difficult and error prone process. By extracting control information directly from the image, the authors free their technique from the errors normally associated with a fixed calibration. The authors demonstrate this by performing a peg-in-hole alignment using an uncalibrated camera to control the positioning of the peg. The algorithm utilizes feedback from a simple geometric effect, rotational invariance, to control the positioning servo loop. The method uses an approximation to the image Jacobian to provide smooth, near-continuous control.
Does marriage matter? Racial differences in allostatic load among women

description:
Prior research suggests that there are health benefits associated with marriage, although the physiological implications of marital status for women's health is less clear. Given that recent trends indicate that Black women are less likely to marry than White women, the goal of this study was to evaluate whether marital status accounts for racial differences in women's physical health. Using data from the Nashville Stress and Health Study (2011–2014), we estimated the probability of high allostatic load (AL), a biological indicator of physiological dysregulation, among women aged 18–69. We examined AL scores by race and marital status, evaluated the extent to which Black-White differences persisted after accounting for marital status, and assessed whether the racial disparity in AL varied across marital status groups. Results indicated that Black women had higher AL than White women, although racial differences in AL were not explained by marital status. In addition, marital status was a significant predictor of AL among Black, but not White women. Moreover, the racial disparity in AL was smallest among never married women and largest among currently and formally married women. Taken together, these findings suggest that Black-White inequalities in women's physical health are not explained by racial differences in marital status, despite the widening racial gap in marriage. Nevertheless, marital status may be an influential factor in shaping outcomes among Black women.

description: This paper discusses the problem of visual control of grasping. We have implemented an object tracking system that can be used to provide visual feedback for locating the positions of fingers and objects to be manipulated, as well as the relative relationships of them. This visual analysis can be used to control open loop grasping systems in a number of manipulation tasks where the finger contact, object movement, and task completion need to be monitored and controlled.
Conversations across the divide : journey of an emerging health care provider
Creators: name: Chiu, David
Publisher: name: University of British Columbia
Year: 2011

description: This is an account of my personal journey of struggles, reflections and realizations as a care provider for individuals who live with cancer. Using the autoethnography method, I asked the very personally relevant question, “How do I understand my role as an emerging health care provider (HCP) to immigrant and young adults with cancer?” In other words, where do I fit in? How can I be the most effective caregiver possible? This telling of my journey incorporates my own experiences as well as the experiences of those who live and work with cancer. The journey begins almost a decade ago with an unexpected phone call that sends me to the bedside of a family member with cancer, and proceeds to my more recent experiences as a family caregiver, volunteer and counselling student and researcher. Drawing on multiple data sources, I explore the concept of health care provider, the desire to protect others and wear masks, and my own feelings of regret and guilt. Although this thesis presents my own realizations and insights, I hope that readers of these stories find resonance or dissonance with their own experiences, allowing them to make more sense of their own roles and circumstances.

description: Atom-number states are a valuable resource for ultracold chemistry, atom interferometry and quantum information processing. Recent experiments have achieved their deterministic preparation in trapped few-fermion systems. We analyze the tunneling decay of these states, both in terms of the survival probability, and the non-escape probability, which can be extracted from measurements of the full counting statistics. At short times, the survival probability exhibits deviations from the exponential law. The decay is governed by the multi-particle Zeno time which exhibits a signature of quantum statistics and contact interactions. The subsequent exponential regime governs most of the dynamics, and we provide accurate analytical expressions for the associated decay rates. Both dynamical regimes are illustrated in a realistic model. Finally, a global picture of multi-particle quantum decay is presented.

TMP21 in Alzheimer's disease : biochemical and behavioural characterization of TMP21
Creators: name: Bromley-Brits, Kelley
Publisher: name: University of British Columbia
Year: 2011

description: Alzheimer's disease (AD) is the most common neurodegenerative disorder leading to dementia. The two major neuropathological hallmarks of AD are the deposition of amyloid-b (Ab) protein in neuritic plaques and the formation of neuro brillary tangles. Ab is generated from a larger Ab recursor protein (APP) following sequential cleavage by b- and g-secretase. APP can also be cleaved in a non-amyloidogenic pathway following sequential cleavage by a- and g-secretase. In addition to the pathogenic processing of APP, the g-secretase complex also cleaves a protein called Notch, which is essential for embryonic development and may be involved in learning and memory. Transmembrane emp24-like trafficking protein 10 (TMP21) is a 21 kDa transmembrane protein involved in vesicular trafficking. Ubiquitously expressed, particularly in the plasma membrane, endoplasmic reticulum, and Golgi, TMP is vital to development, and homozygous knockout mice are embryonic lethal. Recently, TMP21 was found to play a second, pivotal role as a regulatory member of the g-secretase complex involved in AD pathogenesis. Knockdown of TMP21 increased Ab production without affecting Notch cleavage, making it a seductive target for AD research (Chen et al., 2006). This thesis shows that, similar to other members of the g-secretase complex, TMP21 is also degraded by the ubiquitin-proteasome pathway, as treatment with proteasomal inhibitors increased TMP21 protein levels in both a time- and dose-dependent manner. Furthermore, overexpression of TMP21 shifted APP processing from the a-secretase to b-secretase pathway in cell culture, and b-secretase and TMP21 could coimmunoprecipitate. This suggests that TMP21 may not only a ffect AD pathogenesis through its modulatory role on g-secretase or its trafficking of APP (Vetrivel et al., 2007), but also through its influence on b-secretase, providing a novel enzymatic target for future study. Finally, this work presents the only in vivo study of the behavioural consequences of TMP21 suppression. Motor function, anxiety, and learning and memory were examined using a comprehensive test battery. Mice heterozygous for TMP21 were found to have slightly enhanced physical abilities, increased anxiety, and potential anxiety-augmented de ficits in hippocampal learning and memory. This data will prove vital when examining future work regarding TMP21 suppression in a mouse model of AD.

· Die meisten Betriebe verfolgen keine altersspezifischen Personalstrategien; für sie sind A ltersstrukturen nur in Einzelfällen ein Gestaltungsfeld.
· Hinsichtlich einer Diskriminierung Älterer geben die Betriebe ein ambivalentes Bild ab: Einerseits wird die Leistungsfähigkeit der – schon beschäftigten – Älteren von den Personalverantwortlichen geschätzt, andererseits ist ca. die Hälfte der Betriebe grundsätzlich nicht oder nur unter Bedingungen bereit, ältere Arbeitnehmerinnen und Arbeitnehmer neu einzustellen. Hier scheinen konkrete Erfahrungen im Betrieb und mehr oder weniger diffuse Vorstellungen über „Ältere allgemein“ bei Personalverantwortlichen im Widerspruch zu liegen.
· Das Angebot an personalpolitischen Maßnahmen speziell für Ältere hängt primär von der Betriebsgröße ab. Je größer ein Betrieb, desto mehr derartige Maßnahmen gibt es. Dies hängt mit den Institutionalisierungs- und Professionalisierungsvorteilen in Personalabteilungen großer Betriebe zusammen und  erlaubt keinen unmittelbaren Rückschluss darauf, dass Großbetriebe Älteren bessere Arbeitsbedingungen bieten können.
· Das Angebot an personalpolitischen Maßnahmen speziell für Ältere hängt darüber hinaus auch vom Anteil Älterer an der Belegschaft ab: Sie haben wenig Sinn in Betrieben, in denen es wenig Ältere gibt, und sie sind nicht spezifisch für Ältere in Betrieben, in denen es viele ältere Mitarbeiter gibt. 
· Personalwirtschaftliche und arbeitsmarktpolitische Initiativen, die die Beschäftigung Älterer verbessern, sollten in zwei Richtungen zielen: die Erwerbstätigkeit im Betrieb zu verlängern und den Eintritt in ein Beschäftigungsverhältnis auch im höheren Erwerbsalter zu unterstützen.

description: We have performed detailed studies of the temperature evolution of the electronic structure in Ba(Fe(1-x)Ru(x))2As2 using Angle Resolved Photoemission Spectroscopy (ARPES). Surprisingly, we find that the binding energy of both hole and electron bands changes significantly with temperature in pure and Ru substituted samples. The hole and electron pockets are well nested at low temperature in unsubstituted (BaFe2As2) samples, which likely drives the spin density wave (SDW) and resulting antiferromagnetic order. Upon warming, this nesting is degraded as the hole pocket shrinks and the electron pocket expands. Our results demonstrate that the temperature dependent nesting may play an important role in driving the antiferromagnetic/paramagnetic phase transition.

description: We study a model of scalar field with a general non-minimal kinetic coupling to itself and to the curvature, and additional coupling to the Gauss Bonnet 4-dimensional invariant. The model presents rich cosmological dynamics and some of its solutions are analyzed. A variety of scalar fields and potentials giving rise to power-law expansion have been found. The dynamical equation of state is studied for two cases, with and without free kinetic term . In both cases phenomenologically acceptable solutions have been found. Some solutions describe essentially dark energy behavior, and and some solutions contain the decelerated and accelerated phases.

description: This paper discusses an approach to automating CAD model acquisition by creating binary space partitioning (BSP) trees from laser range data. Distinct views of the object, each represented by a BSP tree, are then merged using set operations. BSP trees have proven their utility in 3D modeling, graphics and image processing, and their tree structure allows efficient algorithms to be developed that are compact and numerically robust. These properties are of primary importance when considering an intermediate representation between raw sensor data and existing CAD models.

description: In der vorliegenden Arbeit wird ein Verfahren zur automatischen Partitionierung von Bildverarbeitungsalgorithmen in ein Hardware-Software Co-Design vorgestellt. Die Algorithmen entsprechen dabei dem allgemeinen Schichtenmodell der Bildverarbeitung (BV). Ziel ist die echtzeitfähige Realisierung eines BV-Algorithmus auf einem eingebetteten System mit minimalen "Kosten". Die als C/C++ Code realisierten Funktionen des BV-Algorithmus werden auf einem PC statisch und dynamisch analysiert. Die Ergebnisse der Analyse bilden die Grundlage für die Partitionierung. Die Partitionierung selbst gliedert sich in zwei Phasen. Die erste Phase stellt die Clusterung der Funktionen zu einem Multiprozessorsystem dar. Reicht das nicht aus, um Echtzeitfähigkeit herzustellen, werden einzelne Funktionen unter Nutzung des Simulated Annealing in Logik überführt, bis die zuvor aufgestellten Echtzeitbedingungen eingehalten werden. Dabei entsteht ein System mit auf Logik und mehrere Prozessoren verteilten Funktionen, das die aufgestellten Anforderungen erfüllt.
description: This work presents a system for automatic partitioning of image processing algorithms in a Hardware/Software Co-Design. The algorithms thereby correspond to the general layered model of image processing (IP). The goal is the real-time implementation of an IP algorithm on an embedded system with minimal costs. The functions of an IP algorithm implemented in C/C++ code are analyzed on a PC statically and dynamically. The results of the analysis form the basis for the partitioning. The partitioning itself is divided into two phases. The first phase constitutes the clustering of functions to a multiprocessor system. If that is not sufficient, in order to manufacture real-time conditions individual functions are transferred to logic using simulated annealing. Therefore, a system develops with logic and several processors as distributed functions, that fullfills the requirements.
Duty Cycle and the Increasing Star Formation History of z>=6 Galaxies

description: We examine the duty cycle and the history of star formation (SFH) for high-redshift galaxies at z>=6 using cosmological hydrodynamic simulations. We find that, even though individual galaxies have bursty SFH, the averaged SFH between z~15 to z=6 can be characterized well by either an exponentially increasing functional form with characteristic time-scales of 70 Myr to 200 Myr for galaxies with stellar masses Ms~10^6 Msun to >10^10 Msun respectively, or by a simple power-law form which exhibits a similar mass dependent time-scales. Using the SFH of individual galaxies, we measure the duty cycle of star formation (DC_SFH); i.e., the fraction of time a galaxy of a particular mass spends above a star formation rate (SFR) threshold which would make it observable to the Hubble Space Telescope (HST) during a given epoch. We also examine the fraction of galaxies at a given redshift that are brighter than a rest-frame UV magnitude (Muv ~ -18), which is sufficient enough to make them observable (DC_Muv). We find that both DC_SFH and DC_Muv make a sharp transition from zero (for galaxies with Ms <= 10^7 Msun) to unity (for Ms > 10^9 Msun). The measured duty cycle is also manifested in the intrinsic scatter in the Ms-SFR relationship (~ 1 dex) and Ms-Muv relationship (ΔMuv ~ +-1 mag). We provide analytic fits to the DC as a function of Ms using a sigmoid function, which can be used to correct for catalogue incompleteness. We consider the effects of duty cycle to the observational estimate of galaxy stellar mass functions (GSMF) and the star formation rate density (SFRD), and find that it results in a much shallower low-mass end slopes of the GSMF and a reduction of >~ 70% of our intrinsic SFRD, making our simulation results more compatible with observational estimates.

description: Cryptographic transformations are a fundamental building block in many security applications and protocols. To improve performance, several vendors market hardware accelerator cards. However, until now no operating system provided a mechanism that allowed both uniform and efficient use of this new type of resource. We present the OpenBSD Cryptographic Framework (OCF), a service virtualization layer implemented inside the kernel, that provides uniform access to accelerator functionality by hiding card-specific details behind a carefully-designed API. We evaluate the impact of the OCF in a variety of benchmarks, measuring overall system performance, application throughput and latency, and aggregate throughput when multiple applications make use of it. We conclude that the OCF is extremely efficient in utilizing cryptographic accelerator functionality, attaining 95% of the theoretical peak device performance, and over 800 Mbit/sec aggregate throughput using 3DES. We believe that this validates our decision to opt for ease of use by applications and kernel components through a uniform API, and for seamless support for new accelerators. Furthermore, our evaluation points to several bottlenecks in system and operating system design: data copying between user and kernel modes, PCI bus signaling inefficiency, protocols that use small data units, and single-threaded applications. We offer several suggestions for improvements and directions for future work.

description: To estimate the feasibility of dense-matter phase transition, we studied the evolution of the central density as well as the baryon chemical potential of accreting neutron stars. We compared the thin-disk accretion with and without the magnetic field torque with the spin-down scenario for a selection of recent equations of state. We compared the prevalent (in the recycled-pulsar context) Keplerian thin-disk model, in which the matter is accreted from the marginally-stable circular orbit, with the recent magnetic-torque model that takes into account the influence of stellar magnetic field on the effective inner boundary of the disk. Calculations were performed using a multi-domain spectral methods code in the framework of General Relativity. We considered three equations of state consistent with the recently measured mass of PSR J1614-2230, 1.97 +- 0.04 M_sun (one of them softened by the appearance of hyperons). If there is no magnetic torque and efficient angular momentum transfer from the disk to the star, substantial central compression is limited to the region of initial stellar masses close to the maximum mass. Outside the maximum mass vicinity, accretion-induced central compression is significant only if the angular momentum transfer is inefficient. Accounting for the magnetic field effectively decreases the efficiency of angular momentum transfer and implies a significant central compression. An efficient angular momentum transfer from a thin disk onto a non-magnetized neutron star does not provide a good mechanism for the central compression and possible phase transition. Substantial central compression is possible for a broad range of masses of slowly-rotating initial configurations for magnetized neutron stars. Accretion-induced central compression is particularly strong for stiff equation of state with a high-density softening.

description: Civilian employment in the food and fiber system fell from over 21 percent of the workforce in 1975 to 18.5 percent in 1985. The system's share of gross national product (GNP) also fell from 20.4 percent in 1975 to 17.5 percent in 1985. The system generated $700.8 billion in GNP and employed 21.4 million full-time workers in 1985. This report reviews procedures used to estimate income and employment in the food and fiber system and their usefulness in economic policy and decisionmaking.

Evidence for a Phase Transition in 2D Causal Set Quantum Gravity

description: We present evidence for a phase transition in a theory of 2D causal set quantum gravity which contains a dimensionless non-locality parameter $ε\in (0,1]$. The transition is between a continuum phase and a crystalline phase, characterised by a set of covariant observables. For a fixed size of the causal set the transition temperature $β_c^{-1}$ decreases monotonotically with $ε$. The line of phase transitions in the $β_c^2$ v/s $ε$ plane asymptotes to the infinite temperature axis, suggesting that the continuum phase survives the analytic continuation.

description: On the mesoscopic scale, electromagnetic forces are of fundamental importance to an enormously diverse range of systems, from optical tweezers to the adhesion of gecko toes. Here we show that a strong light-driven force may be generated when a plasmonic metamaterial is illuminated in close proximity to a dielectric or metal surface. This near-field force can exceed radiation pressure and Casimir forces to provide an optically controlled adhesion mechanism mimicking the gecko toe: at illumination intensities of just a few tens of nW/um^2 it is sufficient to overcome the Earth's gravitational pull.

Optimal state discrimination with a fixed rate of inconclusive results: Analytical solutions and relation to state discrimination with a fixed error rate
Creators: name: Herzog, Ulrike
Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We study an optimum measurement for quantum state discrimination, which maximizes the probability of correct results when the probability of inconclusive results is fixed at a given value. The measurement describes minimum-error discrimination if this value is zero, while under certain conditions it corresponds to optimized maximum-confidence discrimination, or to optimum unambiguous discrimination, respectively, when the fixed value reaches a definite minimum. Using operator conditions that determine the optimum measurement, we derive analytical solutions for the discrimination of two mixed qubit states, including the case of two pure states occurring with arbitrary prior probabilities, and for the discrimination of N symmetric states, both pure and mixed. We also consider a case where the given density operators resolve the identity operator, and we specify the optimality conditions for the case of partially symmetric states. Moreover, we show that from the complete solution for arbitrary values of the fixed rate of inconclusive results one can always obtain the optimum measurement in another strategy where the error rate is fixed, and vice versa.
