Factors influencing self-management behavior during the “Blanking Period” in patients with atrial fibrillation : A cross-sectional study based on the information-motivation-behavioral skills model

Background: Atrial fibrillation (AF) is becoming increasingly common. Effective self-management during the “Blanking Period” is critical. The Information-Motivation-Behavioral skills (IMB) model can be used to study health behaviors in chronic disease patients, but it has not been studied in AF patients. Objective: The goal of this study was to explore the influencing factors and interaction pathw

A 50 µm acoustic resonator microchannel enables focusing 100 nm polystyrene beads and sub-micron bioparticles

The manipulation and focusing of submicron/nanometre-scale objects are becoming increasingly important in the fields of biology, chemistry, and materials science. Acoustofluidics provides for the high throughput and precise manipulation of cells and particles with simple equipment. However, application to submicron/nanoparticles is challenging due to the particle volume dependence of the acoustic

Necrorobotics: The Ethics of Resurrecting the Dead

By drawing from recent progress in AI, this chapter scrutinises implications of a specific imaginary of automated futures: the possible resurrection of the dead. Necrorobotics is proposed as a field of critical studies on the use of data and design based on one specific dead individual in order to “resurrect” that individual. That is, to mimic or create some level of robotic agency for the sake of

European pollen-based REVEALS land-cover reconstructions for the Holocene : Methodology, mapping and potentials

Quantitative reconstructions of past land cover are necessary to determine the processes involved in climate-human-land-cover interactions. We present the first temporally continuous and most spatially extensive pollen-based land-cover reconstruction for Europe over the Holocene (last 11g€¯700g€¯calg€¯yrg€¯BP). We describe how vegetation cover has been quantified from pollen records at a 11 spatia

Impact of cracks on distribution of chloride-induced reinforcement corrosion

Surface crack width is regulated in codes to limit corrosion of reinforcement bars in concrete. However, the influence of surface crack width on corrosion damages is not directly inferable from previous research.In this work, data on corroded cracked concrete specimens in chloride environments was compiled. Detailed information was included, such as crack and pit locations, local corrosion pattern

Deep learning can yield clinically useful right ventricular segmentations faster than fully manual analysis

Right ventricular (RV) volumes are commonly obtained through time-consuming manual delineations of cardiac magnetic resonance (CMR) images. Deep learning-based methods can generate RV delineations, but few studies have assessed their ability to accelerate clinical practice. Therefore, we aimed to develop a clinical pipeline for deep learning-based RV delineations and validate its ability to reduce

Det är insidan som räknas - En fallstudie om motivation i ett stort, men platt, svenskt IT-företag

Studien visar att det är de inre motivationsfaktorerna som är viktigast för de anställda samtidigt som den också visar att uppfyllandet av Herzbergs hygienfaktorer ger mer än neutral tillfredsställelse hos de anställda på Techleverantören. Trots att lönerna är lägre än branschgenomsnittet har företaget lyckats skapa ett helhetspaket som gör att de anställda både trivs och hålls motiverade i jobbetThe study shows that it is intrinsic motivation that has the most significance to the employees while simultaneously showing that the fulfilling of Herzberg’s hygiene factors provide more than a neutral satisfaction for the employees at “Techleverantören”. Despite wages being lower than the industry average the company has successfully created a comprehensive package of benefits that make employee

Recombinant yeast for production of the pain receptor modulator nonivamide from vanillin

We report on the development of a method based on recombinant yeast Saccharomyces cerevisiae to produce nonivamide, a capsaicinoid and potent agonist of the pain receptor TRPV1. Nonivamide was produced in a two-step batch process where yeast was i) grown aerobically on glucose and ii) used to produce nonivamide from vanillin and non-anoic acid by bioconversion. The yeast was engineered to express

Investigation and optimization on melting performance of a triplex-tube heat storage tank by rotational mechanism

Phase change heat storage is the backbone of energy storage technology, but its storage time is affected by the low thermal conductivity of phase change materials. Therefore, the melting performance of a triplex-tube latent heat thermal energy storage unit (T-LHTESU) in a phase change heat storage system is studied in this paper, and the rotation mechanism is applied to the unit. Firstly, a numeri

Rapid microwave-stimulated fixation of entire prostatectomy specimens

Conventional fixation of large solid surgical specimens is a slow process. Consequently, autolytic damage to tissues may occur if the fixative does not reach the central part of the specimen in time. However, as there is also a time relationship between formalin fixation and antigen masking, fixation for too long can also be detrimental. In seeking the optimum balance for fixation, microwave irrad

Plasma p-tau217 predicts in vivo brain pathology and cognition in autosomal dominant Alzheimer's disease

Introduction: Plasma-measured tau phosphorylated at threonine 217 (p-tau217) is a potential non-invasive biomarker of Alzheimer's disease (AD). We investigated whether plasma p-tau217 predicts subsequent cognition and positron emission tomography (PET) markers of pathology in autosomal dominant AD. Methods: We analyzed baseline levels of plasma p-tau217 and its associations with amyloid PET, tau P
