Utrikesnytt i YA då och nu

Över tid har stora förskjutningar mellan olika kategorier av nyhetsmaterial ägt rum i en lokaltidning som Ystads Allehanda.I den här artikeln ligger fokus på utrikesnyheternas minskade och det lokala materialets ökade betydelse.Förskjutningen mellan dessa båda kategorier exemplifieras med en jämförelse mellan åren 1939 och 2025.

Deer diary - Evolution of deer antlers: allometry, adaptation or phylogenetic signal?

The variation in length of antlers in deer (Cervidae) has been attributed predominantly to body sizes and the intensity of sexual selection. However, the diversity in antler morphology goes beyond lengths. Using a time-calibrated phylogeny of Cervidae and a newly collected data of antler lengths and volumes, we investigated the evolution of antler morphology within a multi-variate phylogenetic com

Fädernas upplevelser och erfarenheter av att närvara vid förlossning

Bakgrund: En förlossning är inte endast kvinnans utan faderns också eftersom det är bådas graviditet, familj, en erfarenhet och upplevelse att dela tillsammans. I de flesta länder har fäder inte alltid fått närvara vid förlossningar men med tidens gång har man upptäckt ett stort behov av detta vilket har lett till en ökning. Syfte: Syfte är att belysa fädernas upplevelser och erfarenheter av vagin

Spatial Ecology of Two Sympatric Arctic Waders Species - Using GPS Tracking to Investigate Space Use and Nest Site Selection in Ruff and Wood Sandpiper in Tavvavuoma, Sweden

Understanding how sympatric species partition resources is critical for biodiversity conservation, particularly in vulnerable ecosystems. As Arctic ecosystems undergo rapid climate change, understanding how animals use space and select habitats becomes essential for effective conservation planning. Advances in technologies can now provide high-resolution data on species movements and habitat use,

Injecting conflict situations in autonomous driving simulation using CARLA

Simulation of conflict situations for autonomous driving research is crucial for understanding and managing interactions between Automated Vehicles (AVs) and human drivers. This paper presents a set of exemplary conflict scenarios in CARLA that arise in shared autonomy settings, where both AVs and human drivers must navigate complex traffic environments. We explore various conflict situations, foc

Performing Participatory Citizenship - Politics and Power in Kerala's Kudumbashree Programme

This article examines the operation of Kudumbashree, the Poverty Eradication Mission for the Indian State of Kerala. Kudumbashree operates through female-only Neighbourhood Groups, which aim to contribute to their participants' economic uplift, and to integrate them with the activities and institutions of local governance. As such, Kudumbashree echoes poverty alleviation programmes elsewhere in th

World-wide impacts of climate change and nitrogen deposition on vegetation structure, composition, and functioning of shrublands

Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta-analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation (e.g. increased precipitation and drought), and nitrogen addition to quantify seven types

Kinship and opportunity: Swedish chain migration to the United States, 1880–1920

Between 1850 and 1930, millions of Europeans emigrated to the United States, attracted by opportunities for a better life. We study the role of migrant networks in fostering emigration, using individual-level Swedish full-count census data for men and women, linked to emigration records. Our findings show that having previously migrating siblings was an important determinant of emigration, particu

Unbiased Drug Target Prediction Reveals Sensitivity to Ferroptosis Inducers, HDAC and RTK Inhibitors in Melanoma Subtypes

Background: The utilization of PD1 and CTLA4 inhibitors has revolutionized the treatment of malignant melanoma (MM). However, resistance to targeted and immune-checkpoint-based therapies still poses a significant problem. Objective: Here, we mine large-scale MM proteogenomic data to identify druggable targets and forecast treatment efficacy and resistance. Methods: Leveraging protein profiles from

Voltage Regulation in Polymer Electrolyte Fuel Cell Systems Using Gaussian Process Model Predictive Control

This study presents a novel approach using Gaussian process model predictive control (MPC) to stabilize the output voltage of a polymer electrolyte fuel cell (PEFC) by regulating hydrogen and airflow rates. Two Gaussian process models capture PEFC dynamics, accounting for constraints like hydrogen pressure and input change rates to reduce predictive control errors. The performance of the physical

Inversion efficiency model yields improved accuracy in MP2RAGE-based T1-mapping in the human brain at 7.0T

Introduction: Estimation of the longitudinal relaxation time T1 from the MP2RAGE pulse sequence is based on a monoexponential signal evolution model. However, magnetization transfer caused by the inversion pulse induces a fast relaxation component which appears as a reduction in the efficiency of the inversion. This may explain the underestimation of T1 derived from MP2RAGE. To address this system

Den utställda idrotten : Idrott som kulturarv på idrottsmuseer i Sverige

The purpose of this dissertation is to explore the heritagisation of Swedish sports, which is examined through studies of five Swedish sports museums of today. Additionally, the disseration explores the heritagisation of Swedish sports in a wider historical perspective, mainly focusing on the years between 1900 and 2000.There are plenty of sports museums in Sweden today, most of them run by amateu

Assessing the elevational synchronization in vegetation phenology across Northern Hemisphere mountain ecosystems under global warming

In recent decades, changes in vegetation phenology have exhibited a tight coupling with global warming. Mountain ecosystems are particularly susceptible to climate change, with high elevations warming faster than lower areas. The inconsistent rate of temperature change across elevations may lead to synchronization of phenological patterns, reducing the differences in phenology timing between high

Optimal Control on Positive Cones

An optimal control problem on finite-dimensional positive cones is stated. Under a critical assumption on the cone, the corresponding Bellman equation is satisfied by a linear function, which can be computed by convex optimization. A separate theorem relates the assumption on the cone to the existence of minimal elements in certain subsets of the dual cone. Three special cases are derived as examp

Attack Stealthiness and Detection of Multiagent Systems : A Zero-Sum Formulation

Cybersecurity has in recent years emerged as a paramount concern in the design and operation of industrial systems and civil infrastructures, due mainly to their susceptibility to malicious cyber attacks which take advantage of the vulnerability of communication networks and IT devices. In this paper, we investigate such an attack and counter attack scenario by considering multiagent systems, a so
