HOMOGENEOUS FORM INEQUALITIES (I) : VOLUME ESTIMATES AND THE GENERALISED METRIC OPPENHEIM CONJECTURE

This is the first part of a work devoted to the study of the set of integer solutions to a system of inequalities determined by homogeneous forms. According to the heuristics that the number of such solutions should match the volume of the set of real solutions, sharp estimates for the volume of the semialgebraic domain under consideration are established. These estimates are expressed as a functi

Lung cancer risk between maternal and paternal half-siblings points to main environmental causation and targets for prevention

Introduction: Familial risk of lung cancer (LC) is at the level of many common cancers (ca 2.0) but as cigarette smoking is the main cause of LC, it has remained undefined to what extent smoking contributes to the familial risk. We take advantage of the natural experiment of divorce. In Sweden, it has been customary that children stay with their mother after divorce. We thus hypothesize that only

The First Chemical Census of the Milky Way’s Nuclear Star Cluster

An important step in understanding the formation and evolution of the nuclear star cluster (NSC) is to investigate its chemistry and chemical evolution. Additionally, exploring the NSC’s relationship to the other structures in the Galactic center and the Milky Way disks is of great interest. Extreme optical extinction has previously prevented optical studies, but near-IR high-resolution spectrosco

Understanding Widening Participation : Teacher Perceptions and Policy Implications at Lund University

Since 2002, Swedish higher education institutions have been mandated by the Higher Education Act to actively promote widening participation. However, there is no national definition of widening participation, leaving each institution to define its own objectives. This article investigates how teachers at Lund University in Sweden understand and implement widening participation, examining their perSince 2002, Swedish higher education institutions have been mandated by the Higher Education Act to actively promote widening participation. However, there is no national definition of widening participation, leaving each institution to define its own objectives. This article investigates how teachers at Lund University in Sweden understand and implement widening participation, examining their per

Nationalism

What is nationalism? When did it originate and how did it develop throughout the centuries? What types of nationalism have evolved in different sociopolitical settings and why? By addressing these questions, this entry seeks to address the key issues of the conceptualization of nationalism, followed by an analysis of its development in different structural, cultural, and political contexts. The en

Enhancing high-energy powder X-ray diffraction applications using a PILATUS4 CdTe detector

Hybrid photon counting detectors have significantly advanced synchrotron research. In particular, the introduction of large cadmium telluride-based detectors in 2015 enabled a whole new range of high-energy X-ray measurements. This article describes the specifications of the new PILATUS4 cadmium telluride detector and presents results from prototype testing for high-energy powder X-ray diffraction

Associations between human non-motorised recreational activity on nest box occupation, exploratory behaviour and breeding success in a passerine bird

Anthropomorphic activities have a large impact on ecosystems in many ways, one of which is how animals behave. Non-motorised nature recreation is a popular human activity of which the impacts on nature are largely unknown. These activities, which include hiking, biking, pet walking and horseback riding, tend to increase during the commencement of the breeding activity for most passerine forest bir

Caring for Young Patients With Traumatic Knee Injury : Why Surgery Isn’t the Only Option

Young adults presenting with knee pain, instability, or both after twisting the knee during sports or at work are commonly seen in primary care. If the symptoms and injury history correspond with suspicion of a torn anterior cruciate ligament (ACL) or meniscal injury, sometimes in combination with positive findings on magnetic resonance imaging, patients are often referred for surgical treatment.

Exploring Intimacy with Artificial Intelligence : Validation of Robot Intimacy Receptivity Scale (RIRS)

Public and scientific interest in human-robot interactions is growing rapidly. As artificial intelligence (AI) becomes an integral part of human experience, there is an urgent need to understand people’s receptivity to it, especially in emotionally intimate or private spheres. Intimate receptivity goes beyond general technology attitudes, carrying potential implications for companionship, mental h

Review : Current groundwater monitoring practices in Rwanda and recommendations for enhancing knowledge of groundwater resources

Although groundwater serves as the predominant source of drinking water across many rural regions and certain urban areas of Rwanda, little is known about this resource. Anthropogenic impacts, such as faecal contamination, as well as geogenic water quality problems, including elevated arsenic, fluoride, iron, and manganese, are among the issues of concern for groundwater quality in Rwanda. Long-te

Safety and efficacy of proton pump inhibitors in preterm infants with gastroesophageal reflux disease

Background: Although physiological reflux is seen in nearly all newborns to varying degrees, symptoms can be severe and cause gastroesophageal reflux disease (GERD). In preterm infants, one symptom that is often attributed to GERD is apnea and associated cardiorespiratory events, such as bradycardia and oxygen desaturation. Although the relationship between GERD and apnea, bradycardia, and desatur

Turbulent Heat Transfer over roughness : a comprehensive review of theories and turbulent flow structure

Turbulent heat transfer over rough surfaces is crucial in natural and industrial processes, yet it has received less attention than that of momentum transfer. Recently, research in this field is rapidly growing, driven by advancements in computational methods, the role of surface roughness in meteorology, and the growing use of Additive Manufacturing technologies for energy and thermal management

A field test on the hydromechanical behaviour of flowing and nonflowing fractures in the 2.5 km COSC-1 borehole in crystalline rock, Sweden

Understanding the initiation, propagation and evolution of water injection-induced fractures is essential for geo-energy applications. Hydromechanical stimulation experiments were conducted in a deep borehole drilled into crystalline bedrock to gain insights into these processes, involving simultaneous in-situ measurements of three-dimensional fracture displacements, injection flow rates, and wate

Patterning effects of FGF17 and cAMP on generation of dopaminergic progenitors for cell replacement therapy in Parkinson’s disease

Cell replacement therapies using human pluripotent stem cell-derived ventral midbrain (VM) dopaminergic (DA) progenitors are currently in clinical trials for treatment of Parkinson’s disease (PD). Recapitulating developmental patterning cues, such as fibroblast growth factor 8 (FGF8), secreted at the midbrain-hindbrain boundary (MHB), is critical for the in vitro production of authentic VM DA prog

Artificial Neural Networks for Flood Prediction in Current and CMIP6 Climate Change Scenarios

Researchers have widely applied discharge simulation using artificial neural networks (ANNs) and have gained prominence in water resources. Morphological features, watershed urbanization, and climate change influence hydrological variables. Thus, data-driven models need to be able to identify the hydrological relationships without explicitly stating the physical processes. The main objectives of t

Hot Rocks Survey I : A possible shallow eclipse for LHS 1478 b

Context. M-dwarf systems offer an opportunity to study terrestrial exoplanetary atmospheres due to their small size and cool temperatures. However, the extreme conditions imposed by these host stars raise a question about whether their close-in rocky planets are able to retain any atmosphere at all. Aims. The Hot Rocks Survey aims to answer this question by targeting nine different M-dwarf rocky p
