The genomic natural history of the aurochs
Now extinct, the aurochs (Bos primigenius) was a keystone species in prehistoric Eurasian and North African ecosystems, and the progenitor of cattle (Bos taurus), domesticates that have provided people with food and labour for millennia1. Here we analysed 38 ancient genomes and found 4 distinct population ancestries in the aurochs—European, Southwest Asian, North Asian and South Asian—each of whicNow extinct, the aurochs (Bos primigenius) was a keystone species in prehistoric Eurasian and North African ecosystems, and the progenitor of cattle (Bos taurus), domesticates that have provided people with food and labour for millennia1.

Vulnerable to heat stress : gaps in international standard metric thresholds
Exposure time to heat is increasing with climate change. Heat exposure thresholds are important to inform heat early warning systems, and legislation and guidance for safety in the workplace. It has already been stated that thresholds can be lower for vulnerable groups, including the elderly, pregnant women, children, and those with pre-existing medical conditions due to their reduced ability to t

On the Distance to Infeasibility in DC Power Grids with Constant-Power Loads
This paper is concerned with the feasibility of the power flow in DC power grids with constant power loads. We introduce the notion of distance to infeasibility as a voltage stability index and robustness measure for power flow feasibility. In particular, we study the p-norm distance to infeasibility in the domain of the constant power loads, and show how this distance may be expressed as a mathem

On the H2 optimal control of uniformly damped mass-spring networks
In this paper we provide an analytical solution to an H2 optimal control problem, that applies whenever the process corresponds to a uniformly damped network of masses and springs. The solution covers both stable and unstable systems, and illustrates analytically how damping affects the levels of achievable performance. Furthermore, the resulting optimal controllers can be synthesised using passiv
The relationship between preoperative sleep disturbance and acute postoperative pain control : A systematic review and meta-analysis
Poor preoperative sleep quality and impaired sleep continuity may heighten acute postoperative pain intensity and increase analgesic consumption, with negative implications for recovery, mental and physical health. The main objective of the current review was to investigate the relationship between preoperative sleep disturbance and acute postoperative pain control. Four electronic databases were
Nonlinear Wave Modulation for the Evaluation of Corroded Steel Plates Embedded in Concrete
Corrosion of steel components embedded in concrete is detrimental to the structural integrity and their intrinsic function,such as the leak-tightness of containment liners in nuclear reactor containment buildings. Detection of embedded linercorrosion is a challenging task due to the concrete’s heterogeneity and the large dimensions of containment buildings.This initial study explores early-stage d
Topological material in the III--V family : Heteroepitaxial InBi on InAs
InBi(0 0 1) is formed epitaxially on InAs(1 1 1)-A by depositing Bi onto an In-rich surface. Angle-resolved photoemission measurements reveal topological electronic surface states, close to the M high symmetry point. This demonstrates a heteroepitaxial system entirely in the III–V family with topological electronic properties. InBi shows coexistence of Bi and In surface terminations, in contradict
A Survey on Channel Sounding Technologies and Measurements for UAV-Assisted Communications
Unmanned aerial vehicles (UAVs) have been widely used in both military and civilian applications, where a stable communication link is vital for safe flight control and robust data transmission. To develop a reliable UAV communication system, it is necessary to deeply understand the UAV channel characteristics and establish accurate channel models. Channel sounding is the most effective way to obt
Polyvinyl fluoride: Predicting polarization in a complex soft matter system
We use first-principle density functional theory (DFT) to predict properties for semicrystalline polyvinyl fluoride (PVF) and compare with polyvinylidiene fluoride. We note that the crystalline regions of PVF are complex in the sense that we lack a complete experimental characterization of the detailed atomic organization. We therefore turn to DFT to predict both the structure and associated mater
Med det förflutna för ögonen
At a retirement it is natural to have the past in front of you, in particular as a historian. But contrary to what we normally think – that we have the past behind us and the future in front of us – all of us in reality look at the future through the past. What we see is not what will happen but what has happened, and, moreover, as interpreted by our experiences of what has happened earlier. The p
Lightweight vehicles in indirect structural health monitoring : Current advances and future prospects
Recent research has explored the potential of using the dynamic response of passing vehicles to conduct Structural Health Monitoring (SHM) efficiently. Various types of vehicles, including cars, vans, trucks, and even manually propelled carts, have been employed in this approach, with different configurations of exciters and receivers. A noteworthy development in this field involves the inclusion
Rural social movements and sustainable agricultural development in sub-Saharan Africa: towards a collaborative research agenda
Agriculture is key to sustainable development globally – particularly incountries where agriculture both accounts for most of the land use andprovides a livelihood for most of the population. We map out a collaborativeresearch agenda aimed at tackling the urgent but poorly understood issue ofthe role of farmer organisations in overcoming political barriers tosustainable and inclusive agricultural
Genomic identification of expressed globulin storage proteins in oat
Introduction: Oats, a highly nutritious cereal known for their health benefits, contain various macromolecules of significant biological value, including abundant and highly digestible proteins. Despite their importance, oat proteins have not been extensively studied. Here, we present a complete set of the expressed globulins genes, which code for the main storage protein in oats as well as their
Ambulance Travel Time Estimation using Spatiotemporal Data
Ambulance travel time estimations play a pivotal role in ensuring timely and efficient emergency medical care by predicting the duration for an ambulance to reach a specific location. Overlooking factors such as local traffic situations, day of the week, hour of the day, or the weather may create a risk of inaccurately estimating the ambulance travel times, which might lead to delayed emergency re
Cellular and Molecular Interplay in Bone Homeostasis and Healing
Bone is a complex hierarchical structure mainly comprising of a matrix of collagen and hydroxyapatite. The main physiological functions of bone include regulating skeletal remodeling, calcium homeostasis and providing a congenial environment to the bone marrow cells to reside and these physiological processes are intricately regulated by various cell types and biomolecules. During trauma to the sk
Scenarios for the long-term efficacy of amyloid-targeting therapies in the context of the natural history of Alzheimer's disease
INTRODUCTION: Recent clinical trials of amyloid beta (Aβ)-targeting therapies in Alzheimer's disease (AD) have demonstrated a clinical benefit over 18 months, but their long-term impact on disease trajectory is not yet understood. We propose a framework for evaluating realistic long-term scenarios. METHODS: Results from recent phase 3 trials of Aβ-targeting antibodies were integrated with an estim
