Emergency Detection in Smart Homes Using Inactivity Score for Handling Uncertain Sensor Data.

In an aging society, the need for efficient emergency detection systems in smart homes is becoming increasingly important. For elderly people living alone, technical solutions for detecting emergencies are essential to receiving help quickly when needed. Numerous solutions already exist based on wearable or ambient sensors.

Nurses' Workplace Perceptions in Southern Germany-Job Satisfaction and Self-Intended Retention towards Nursing.

Our cross-sectional study, conducted from October 2022 to January 2023, aims to assess post-COVID job satisfaction, crucial work dimensions, and self-reported factors influencing nursing retention. Using an online survey, we surveyed 2572 nurses in different working fields in Bavaria, Germany. We employed a quantitative analysis, including a multivariable regression, to assess key influence factors on nursing retention.

Exploiting Smart Meter Power Consumption Measurements for Human Activity Recognition (HAR) with a Motif-Detection-Based Non-Intrusive Load Monitoring (NILM) Approach.

Numerous approaches exist for disaggregating power consumption data, referred to as non-intrusive load monitoring (NILM). Whereas NILM is primarily used for energy monitoring, we intend to disaggregate a household's power consumption to detect human activity in the residence. Therefore, this paper presents a novel approach for NILM, which uses pattern recognition on the raw power waveform of the smart meter measurements to recognize individual household appliance actions.

Influence of calibration on digital templating of hip arthroplasty.

Introduction: Digital templating for total joint replacement is the current standard. For image calibration, external calibration markers (ECM) are used. However, there are concerns regarding the precision of the method.

Dual-position calibration markers for total hip arthroplasty: theoretical comparison to fixed calibration and single marker method.

Purpose: Digital templating is considered a standard for total hip arthroplasty. Different means for the necessary calibration of radiographs are known. While single marker calibration with radiopaque spheres is the most common, it is associated with possible significant deviations from the true magnification of the hip.

Influence of tissue fixation on the microextraction and identification of amyloid proteins.

In surgical pathology, correct immunohistochemical identification of AL amyloidosis poses a particular problem. Immunostaining for lambda- or kappa-light chains is commonly encountered even in non-immunoglobulin-derived amyloidoses, which leads to a false-positive classification as AL amyloidosis. In this respect, microextraction of amyloid proteins from surgical pathology specimens and their subsequent biochemical characterization may prove useful in reaching the correct diagnosis.
