STUDY OBJECTIVE: Male sex has inconsistently been associated with the development of postoperative pulmonary complications (PPCs). These studies were different in size, design, population and preoperative risk. We reanalysed the database of 'Local ASsessment of Ventilatory management during General Anaesthesia for Surgery study' (LAS VEGAS) to evaluate differences between females and males with re

Quinoa is globally recognised for its nutritional value, and its production has recently expanded worldwide. However, Quinoa Real (Royal Quinoa), a landrace group grown exclusively in the Intersalar zone of Bolivia, stands out for its grain quality and adaptation to extreme environments, such as high altitude, high salinity, intense UV radiation, aridity, and temperature fluctuations. This study c

Energy Management Systems (EMSs) often operate through inflexible, rule-based control systems. Model-free reinforcement learning (RL) has emerged as a promising alternative, providing adaptive and autonomous control without the need for detailed modeling. However, the complexity of operating energy systems and dynamic environmental conditions limits their practical use, with most studies relying o

In this paper, we present a system for drone detection and positioning. The approach uses a system composed of an audio detection rig with a set of microphones, a set of fixed cameras with a large combined field of view and a Pan-TiltZoom camera. We present how this system can be defined in an efficient and modular way with a number of parallel sensing modules. The focus of this work is the audio

This paper presents a method for mathematical modelling of surfaces conditioned on empirical data. It is based on solving a discrete biharmonic equation over a domain with given inner point and inner curve data. The inner curve data is used to model boundary values while the inner point data is used for modeling a load vector with the goal to generate a smooth surface. The construction of boundary

Three-dimensional finite element (FE) models derived from Computed Tomography (CT) images predict hip fractures better than areal bone mineral density measurements from Dual-energy X-ray Absorptiometry (DXA). Yet, these results have not justified the adoption of CT in clinical practice, and only 2D DXA images are clinically available. Statistical shape and appearance models can be used to reconstr

Kapitlet fokuserar på barn i familjer som sökt asyl i Sverige. Med en utvecklingspsykologisk utgångspunkt adresseras barnens situation och konsekvenserna för deras utveckling och välbefinnande av ett otillräckligt skydd och stöd. Med ett rättighetsbaserat perspektiv diskuteras barnens folkrättsliga skydd samt hur detta upprätthålls i Sverige. Vi avslutar med en reflektion kring prioriteringar fram

Background: Women who have undergone cervical conization may still experience subsequent pregnancies and delivery. However, it remains unknown whether pregnancy, associated with immune tolerance, might increase the risk of subsequent cervical lesions. This study aims to address this knowledge gap by utilizing the nationwide Swedish registers. Methods: A total of 60,895 women diagnosed with cervica

The article examines how the audiobook’s increasing centrality on the contemporary book market influences publishing strategies. Departing from the case of Sweden, where audiobooks are primarily distributed via subscription-based streaming services, the article is based on interviews with 12 Swedish publishers and streaming service representatives. Thus, it contributes with a producer perspective

As the impact of climate change intensifies, there is an urge to adapt Swedish residential buildings with a special focus on improving their energy efficiency and resilience. In this study, adaptive strategies through Artificial Intelligence and Reinforcement Learning will be provided for the energy management of different Swedish residential buildings. The aim will be the optimization of energy u

In this paper we present a method for line segment detection in images, based on a semi-supervised framework. Leveraging the use of a consistency loss based on differently augmented and perturbed unlabeled images with a small amount of labeled data, we show comparable results to fully supervised methods. This opens up application scenarios where annotation is difficult or expensive, and for domain

Gold particles are commonly used as catalysts in the vapor-liquid-solid (VLS) growth of GaAs nanowires, but the incorporation of gold into the nanowires can negatively affect their electronic and optical properties. In this work, we investigate the equilibrium concentration of Au in GaAs nanowires using density functional theory calculations combined with thermodynamically assessed chemical potent

Den 10 maj 2024 försvarade Andreas Stephens sin avhandling i teoretisk filosofi vid Lunds universitet. Här presenterar han en kort sammanfattning.

Vi är forskargruppen Rättigheter, regleringar och samhälle vid Avdelningen för fas-tighetsvetenskap, Institutionen för teknik och samhälle, LTH, Lunds universitet. Vi har bedrivit och bedriver forskning om regleringen av skogsbruk, mestadels ur ett rättsekonomiskt perspektiv. Vi har bl.a. studerat tillämpningen av Artskyddsförord-ningen och Århuskonventionen. I vår forskning har vi kunnat konstate

Individual’s future socioeconomic status (SES) has been reported to be robustly predicted by cognitive ability (IQ). However, research on the genetic and environmental underpinnings of this association in emerging adults remains limited. Utilizing the German TwinLife panel data, the present study examined how IQ at early adulthood at age 23 is associated with SES at age 27 (NMZ = 228 and NDZ−SAME

Inappropriate bricklaying techniques can result in extruded mortar joints, which may partially fill the air gaps within brick veneer timber frame walls. This leads to an unintended connection or “bridge” between the brick masonry cladding and its adjacent layer (such as insulation or weather-resistant barriers). This bridging effect compromises the capillary break function of the air gap, allowing

Highly insulated external wall assemblies are commonly employed to enhance building energy performance. However, research indicates that these assemblies may lead to moisture-related issues, such as mould growth. Recent studies suggest that the use of highly hygroscopic insulation materials, owing to their higher moisture buffering value, may mitigate relative humidity levels and consequently the

Throughout the last decades, the social responsibility of corporations has undergone significant changes. From revolving around self-regulation, voluntariness, and soft law, the regulatory landscape has expanded to involve harder demands on corporations, such as mandatory sustainability due diligence. This thesis considers these changes as a hardening of Corporate Social Responsibility (CSR), and
