Background Stress is a major risk factor for the impairment of psychological well-being. The present study aimed to evaluate empirical evidence Transactional Model proposed by Lazarus and Folkman in patients with psychosomatic health conditions. Methods A structural equation model was applied two separate subsamples inpatients from Department Psychosomatic Medicine (total n = 2,216) consecutive building (sample 1, 1,129) confirmatory analyses 2, 1,087) using self-reported status information...
High-flux hemodialysis (HD) and high-dose hemodiafiltration (HDF) are established treatments for patients with kidney failure. Since HDF has been associated improved survival rates compared to HD, we evaluated the cost-effectiveness of HD. Cost-utility analyses were performed from a societal perspective alongside multinational randomized controlled CONVINCE trial. A Markov cohort model was used extrapolate results lifetime time horizon. Costs dialysis sessions based on published data, two...
Impairment in personality functioning (PF) has been linked to a number of mental disorders, including eating disorders (EDs). However, the precise relationship between PF and symptom severity, as well potential impact on outcome, remains unclear. The study aimed analyse association its change with severity ED symptomatology outcome hospital treatment. sample consisted 397 patients EDs, treated 19 university hospitals for Psychosomatic Medicine Psychotherapy Germany 1/2019 12/2020. was...
This paper describes an adaptive gate control technique and a driver concept for isolated power devices. The proposed modulates the current of devices to dv/dt di/dt during switching transition. It uses different time intervals, which are adjusted successively. Delays section compensated therefore is applicable fast transients. To detect switching, feedback path implemented using parasitic inductances in converter. By application this method, we achieved following properties: low propagation...

This work presents a driver and controller integrated circuit (IC) for depletion-mode gallium nitride (GaN) high-electron-mobility transistors (HEMTs). The dual-mode can be configured cascode-drive (CD) or HEMT-drive (HD) mode. In the CD mode, cascode low-voltage DMOS is driven to achieve high-speed normally OFF operation. An active clamping proposed breakdown protection. HD an HEMT gate with negative drive-voltage capability programmable slope control presented. A digital peak current-mode...
This paper highlights the general trend towards further monolithic integration in power applications by enabling management and interfacing solutions advanced CMOS nodes. The need to combine high-density digital circuits, power-management robust interfaces a single technology platform requires development of additional process options on top baseline CMOS. Examples include high-voltage devices, devices enable area-efficient ESD protection, integrated capacitors inductors with high quality...
As electric vehicles are gaining increasing worldwide interest, advances in driving range and safety become critical. Modern automotive battery management systems (BMS) compete with challenging performance requirements need to monitor a large amount of parameters. In this paper, we propose power line communications (PLC) for high voltage (HV) traction batteries reduce the BMS wiring effort. By modeling small-scale pack frequencies up 300 MHz, predict PLC channel transfer characteristics...
Power line communication (PLC) in automotive traction batteries is considered an attractive alternative to the serial-bus used state-of-the-art battery management systems (BMS). PLC uses power as medium and saves additional wires, connectors isolation effort. In this work, we present a proof of concept for small-scale pack. From hardware approach, develop modem, which modulates UART data using on-off-keying (OOK) couples it onto line. To test PLC, design demonstrator consisting two modems...
This paper presents a methodology to evaluate different integrated-circuit substrate technology options in terms of interference coupling. It is based on the electromagnetic characterization configurations as radial multilayered dielectric lossy open waveguides and selection propagation modes that effectively contribute In addition, attenuation patterns are obtained for technologies, doping profiles, frequencies, mechanisms order provide tool early prediction, compatibility performance...
Recent developments in the dimensional assessment of personality functioning have made implementation latent measurement models increasingly attractive. In this study, we applied item response theory (IRT) to a well-established instrument (the OPD Structure Questionnaire) identify unidimensional trait and evaluate feasibility computer adaptive testing (CAT). We hypothesized that use IRT could reduce test burden – compared fixed short form while maintaining high precision over wide range...
This paper presents a novel approach to improve the dynamic response of inductive dc-dc converters in applications having repetitive load profiles. In many Internet-of-Things (IoT) applications, such as wireless sensor networks (WSN), current profile has periodic nature, and is therefore predictable by power management circuits. unique nature exploited proposed Preemptive Concurrent Controller (PCC) achieve superior theoretical limits time-optimal control. The preemptive controller ramps up...

: Comparing outcomes across different health measurement tools is essential where various patient-reported outcome measures (PROMs) are used. In spinal surgery, recent studies show that over 30 PROMs applied, this need becomes even more pressing. Although several statistical transformations between the Oswestry Disability Index (ODI) and PROMIS Profile 29 have been proposed, validation on conversion equations cross-walk tables remain limited. study, we examined agreement observed ODI scores...
