Chest computed tomography (CT) imaging with the use of an artificial intelligence (AI) analysis program has been helpful for the rapid evaluation of large numbers of patients during the COVID-19 pandemic. We have previously demonstrated that adults with COVID-19 infection with high-risk obstructive sleep apnea (OSA) have poorer clinical outcomes than COVID-19 patients with low-risk OSA. In the cur

Coherence is a useful measure in many engineering applications. Here, we focus on the case where the input signal to a linear system can be measured free from noise, but the output signal is perturbed by noise. A novel expression for the expectation of a multitaper magnitude squared coherence estimate for this case is presented and verified through numerical evaluation. Additionally, the expressio

This study aimed to effectively decontaminate fuel oil-contaminated soil using ex-situ bioremediation. Soil samples (contaminated with waste oils) from Serbia were treated. The results showed several significant changes after bioremediation. The pH levels became slightly more alkaline (7.0–7.5). Reduction in organic substance (34%) and carbonate (36%) were observed, respectively. The concentration

Formants (vocal tract resonances) are increasingly analyzed not only by phoneticians in speech but also by behavioral scientists studying diverse phenomena such as acoustic size exaggeration and articulatory abilities of non-human animals. This often involves estimating vocal tract length acoustically and producing scale-invariant representations of formant patterns. We present a theoretical frame

Purpose/Aim of the study: Diabetic retinopathy (DR) is a leading cause of blindness in working age adults in developed countries. Changes in metabolites and in metabolic pathways of the retina caused by hyperglycemia may compromise the physiology of the retina. Using nuclear magnetic resonance (NMR) spectroscopy, we aimed to investigate the effect of diabetes on the levels of intermediate metaboli

A compressor map with variations in component level characteristics is introduced. This novel approach to plot component level characteristics identify and give context to the critical design parameters such as flow angles, pressure coefficients, and loss coefficients across the entire compressor map along with the conventional performance parameters. Compressor design involves a significant amoun

I takt med den utbredda digitaliseringen av samhället blir personer allt mer medvetna om säkerheten. Ansiktsigenkänning genom AI har skapat omfattande debatter som ofta är kopplade till en slags oro om övergripande säkerhet i relation till övervakningen i samhället. Med hjälp av kvalitativa intervjuer har vi valt att studera datastudenters inställning till ansiktsigenkänning och påföljderna de ser

Counterfactual history constitutes a prominent subgenre of speculative fiction. Nevertheless, though diverging from actual historical events, such works tend to otherwise be highly realistic. Other speculative fiction goes much further, creating not only an alternative timeline but an alternate reality governed by different physical laws. This chapter coins the term “counterphysical” to describe l

This study aimed to examine how empathy is portrayed in picture books for children aged 3-6. A total of 18 library books were analyzed using a qualitative content analysis, which consisted of a compilation of image and text analysis. By applying a psychological, social psychological, and communicative perspective on the empirical material, several aspects of empathy expressions were made visible.

This paper aims to analyze economical factors behind urban decay, also referred to as slums, in The United States and particularly vulnerable areas in Sweden. The purpose with this paper is to conclude whether or not urban decay in the U.S can be compared with particularly vulnerable areas in Sweden by examining the predominant economic factors behind decayed and particularly vulnerable areas in e

This paper investigates the literature concerning market efficiency and how that compares to behavioral finance. The works of Fama (1970) who laid the ground for the efficient market hypothesis and Jegadeesh & Titman (1993) who laid the ground for momentum strategies are both analyzed and compared against each other. A momentum study on the weekly returns regarding the Swedish stock market (OM

Epigenetic dysregulation may influence disease progression. Here we explore whether epigenetic alterations in human pancreatic islets impact insulin secretion and type 2 diabetes (T2D). In islets, 5,584 DNA methylation sites exhibit alterations in T2D cases versus controls and are associated with HbA1c in individuals not diagnosed with T2D. T2D-associated methylation changes are found in enhancers

Considering recent developments in the energy sector, further reduction of electricity cost and flattening of the electric power demand curve are needed. We have focused on an autonomous electric heater control system that can easily be implemented in existing buildings without strict comfort requirements. Examples are winter heating of warehouses and vacation homes, and heat drying of buildings u

The recently developed Phase-Scaled Reassignment (PSR) can estimate phase-difference between two oscillating transient signals with high accuracy. However, in low signal-to-noise ratios (SNRs) the performance of commonly applied reassignment techniques is known to deteriorate. In order to reduce variance in low SNR, we propose a multitaper PSR (mtPSR) method for phase-difference estimation between

Background and aims: Alcohol use disorder (AUD) is one of the strongest predictors of suicidal behavior. Here, we measured risk of suicide attempt and death as a function of AUD typologies. Design: We used AUD typologies from previous latent class analysis: (i) externalizing subtype (characterized by externalizing symptomatology and early age of onset; individuals in this group have lower educatio

Under slaget om Guadalcanal 1942 sänktes USS Juneau. Ombord tjänstgjorde fem bröder i familjen Sullivan. Alla omkom vilket uppmärksammades på bred front i samtiden och deras öden utgjorde senare inspiration för filmen Rädda meinge Ryan.
