Serious physical assault and subsequent risk for rehospitalization in individuals with severe mental illness: a nationwide, register-based retrospective cohort study.

BACKGROUND: Victimization is associated with worse social and clinical outcomes of individuals with severe mental illness (SMI). A relapse of SMI may be one of the clinical consequences of assaultive trauma. As far as we know, there is no published study that analyzes nationwide health registers to assess the risk of SMI rehospitalization following assault. AIM: We aimed to assess whether exposure to assault is associated with an increased risk of psychiatric hospitalization in those with SMI. METHODS: We utilized data from the Czech nationwide registers of all-cause hospitalizations and all-cause deaths. We defined exposed individuals as those discharged from a hospitalization for SMI between 2002 and 2007, and hospitalized for serious injuries sustained in an assault in the subsequent 7 years. For each assaulted individual, we randomly selected five counterparts, matched on SMI diagnosis, age and sex, who were not assaulted in the examined time period. We used mixed effect logistic regression to assess the effect of assault on the risk of SMI rehospitalization within the following 6 months. We fitted unadjusted models and models adjusted for the number of previous SMI hospitalizations and drug use disorders. RESULTS: The sample consisted of 248 exposed and 1 240 unexposed individuals. In the unadjusted model, assaulted individuals were almost four times more likely to be rehospitalized than their non-assaulted counterparts (odds ratio (OR) = 3.96; 95% CI 2.75; 5.71). After adjusting for all covariates, the OR remained threefold higher (OR = 3.07; 95% CI 2.10; 4.49). CONCLUSION: People with a history of SMI hospitalization were approximately three times more likely to be rehospitalized for SMI within 6 months after an assault than their non-assaulted SMI counterparts. Soon after a person with SMI is physically assaulted, there should be a psychiatric evaluation and a close follow-up

Ubiquitäre Systeme (Seminar) und Mobile Computing (Proseminar) SS 2019 : Mobile und Verteilte Systeme Ubiquitous Computing. Teil XIX

Die Seminarreihe Mobile Computing und Ubiquitäre Systeme existiert seit dem Wintersemester 2013/2014. Seit diesem Semester findet das Proseminar Mobile Computing am Lehrstuhl fur Pervasive Computing System statt. Die Arbeiten des Proseminars werden seit dem mit den Arbeiten des zweiten Seminars des Lehrstuhls, dem Seminar Ubiquitäre Systeme, zusammengefasst und gemeinsam veröffentlicht. Die Seminarreihe Ubiquitäre Systeme hat eine lange Tradition in der Forschungsgruppe TECO. Im Wintersemester 2010/2011 wurde die Gruppe Teil des Lehrstuhls für Pervasive Computing Systems. Seit dem findet das Seminar Ubiquitäre Systeme in jedem Semester statt. Ebenso wird das Proseminar Mobile Computing seit dem Wintersemester 2013/2014 in jedem Semester durchgeführt. Seit dem Wintersemester 2003/2004 werden die Seminararbeiten als KIT-Berichte veröffentlicht. Ziel der gemeinsamen Seminarreihe ist die Aufarbeitung und Diskussion aktueller Forschungsfragen in den Bereichen Mobile und Ubiquitous Computing. Dieser Seminarband fasst die Arbeiten der Seminare des Sommersemesters 2019 zusammen. Wir danken den Studierenden für ihren besonderen Einsatz, sowohl während des Seminars als auch bei der Fertigstellung dieses Bandes

WiMAX in Coastal Traffic and Performance Prediction in a Geographically Challenging Environment

This thesis takes upon itself to describe the medium of the radio channel for a WiMAX installation in a difficult environment. Furthermore it investigates the possibility of modifying the WiMAX standard in order to increase per- formance in such an environment. Channel estimators are crucial in optimizing throughput in WiMAX. Their performance is dependent on the amount of information in the pilot subcarriers of WiMAX. A way of adding information to the channel esti- mators without taking more of the bandwidth is to use a model in series with the data estimates. An already existing Kalman filter based algorithm for radio channel estimation is studied and compared to a WiMAX model. Modifications are suggested to fit the WiMAX signals. To extend a network fast in areas where there is little or no infrastructure to begin with is a task that can be performed by ad hoc network solutions. A statistical model for outage in ad hoc networks is studied and an evalua- tion on WiMAX\u92s capability of operating in an Ad hoc network structure is performed

A detailed analysis of ion-acoustic waves observed in the solar wind by the Solar Orbiter

International audienceIon-acoustic waves are often observed in the solar wind along the Solar Orbiter's orbit. These electrostatic waves are generated via ion-ion or current-driven instabilities below the local proton plasma frequency. Due to the Doppler shift, they are typically observed in the frequency range between the local electron and proton plasma frequency in the spacecraft frame. Ion-acoustic waves often accompany large-scale solar wind structures and play a role in the energy dissipation in the propagating solar wind. Time Domain Sampler (TDS) receiver, a part of the Radio and Plasma Waves (RPW) instrument, is sampling wave emissions at frequencies below 200 kHz almost continuously from the beginning of the mission. Almost three years of observations allow us to perform a detailed study of ion-acoustic waves in the solar wind under variable plasma conditions. The emission tends to be observed when proton density and temperature are highly perturbed. A detailed analysis of the proton velocity distribution and wave generation using solar wind data from a Proton and Alpha particle Sensor (PAS) of the Solar Wind Analyzer (SWA) is shown

Experimental and theoretical study of phase separation in ZnPc:C₆₀ blends

Understanding the relationship between the absorber layer microstructure and the power conversion efficiency is of paramount importance to further improve the efficiency of organic solar cells. Utilizing transmission electron microscopy (TEM), (photo-)conductive atomic force microscopy ((p)cAFM), 3D drift-diffusion simulations, and density functional theory, we reveal the microscopic origins of phase-separation in a blend of zinc phthalocyanine (ZnPc) and C60, used as an absorber layer in organic solar cells. By means of (p)cAFM, we observe photoconductive, circular structures at the surface, which are identified as α-ZnPc islands. Moreover, in agreement with TEM investigations, we observe photoconductive, nanorod-like structures close to the surface which we assign to β-ZnPc. Finally, we apply a 3D drift-diffusion simulation based on the morphology determined by TEM to provide a link between the different contrasts observed in (p)cAFM and TEM
