Zone folded coherent acoustic phonons were generated in a multilayered GaSb/InAs epitaxial heterostructure via rapid heating by femtosecond laser pulses. These phonons were probed by means of ultrafast x-ray diffraction. Phonons both from the fundamental acoustic branch and the first back-folded branch were detected. This represents the first clear evidence for phonon branch folding based directly
Microsphere-based constitutive models are a helpful tool in the modelling of materials with a microstructure composed of contributing elements directionally arranged. This is the case, for instance, for fibred soft tissues. In these models, the macroscopic mechanical behaviour is obtained from the integration of the micro-structural contribution of each component (e.g. each fibre) over the surface
As a consequence of heightened concern for the greenhouse effect, depleting oil reserves and skyrocketing oil prices, renewable fuels, Such as bioethanol, are becoming increasingly important. Cellulosic biomass like wood, agricultural residue and herbaceous material is a huge, cheap natural resource that can be used for ethanol production. Decreasing production costs through technological developm
There is a need for efficient techniques to assess abnormalities in the peripheral regions of the lungs, for example, for diagnosis of pulmonary emphysema. Considerable scientific efforts have been directed toward measuring lung morphology by studying recovery of inhaled micron-sized aerosol particles (0.4-1.5 μm). In contrast, it is suggested that the recovery of inhaled airborne nanoparticles ma
Rationale and Objectives: The effects of locally delivered angiogenic factors or stem cells on the coronary artery perfusion territory are not well defined. Therefore, the aim of this study was to determine the ability of the selective injection of magnetic resonance contrast media (MR-CM) to map and quantify the territories of the major coronary arteries. Materials and Methods: Selective coronary
We present the red-listed plants and fungi that have been found in the central parts of the parish of Stenbrohult, southern Sweden. In the middle of the study areas Carl Linnaeus was born in 1707, and he spent his summers there until 1727. Of the 11 currently red-listed vascular plants (Gärdenfors 2000) that have been recorded since 1970 all occurred there also 300 years ago. Mosses, lichens and f
Molecularly imprinted polymers (MIPs) are artificial plastic materials that mimic antibodies or enzymes. Like natural antibodies or enzymes, molecularly imprinted polymers can selectively bind target molecules or can promote catalytic reactions. In contrast to these natural entities, they are robust materials that resist heat, harsh chemicals and the presence of organic solvents. The starting mate
Expressions for first-order induced electronic transition matrix elements are derived within the coupled-cluster response theory framework. When combined with electric-dipole and spin-orbit operators, these matrix elements allow the calculation of radiative transition probabilities between singlet ground and triplet excited states. An implementation employing an atomic mean-field representation of
We study temporally localized electron wave packets, generated using a train of extreme ultraviolet (XUV) attosecond pulses to ionize the target atoms. Both the electron wave packets and the attosecond pulse train ( APT) are characterized using the same technique, based on interference of two-photon transitions in the continuum. We study, in particular, the energy transfer from a moderately strong
This thesis examines whether the partially owned parent entity (POPE) rule in the Directive (EU) 2022/2523 (P2D) creates a restriction on the free movement of capital under Article 63 TFEU, and if so, whether that restriction be justified and regarded as proportionate under EU law. The POPE rule forms part of the EU implementation of Pillar Two, which aims to ensure a global minimum level of taxa

Introduction Osteoarthritis (OA) is the most common form of arthritis and a leading cause of disability worldwide. Metabolic comorbidities such as type II diabetes occur with a higher rate in people with OA than in the general population. Several factors including obesity, hyperglycaemia toxicity and physical inactivity have been suggested as potential links between diabetes and OA, and have been
Cerebral ischemia that develops after subarachnoid hemorrhage (SAH) carries high morbidity and mortality. Inflammatory mediators are involved in the development of cerebral ischemia through activation of the mitogen-activated protein kinase pathway. We hypothesized that blockade of the MAPkinase/ERK (MEK)/extracellular signal-regulated kinase (ERK) pathway upstream with a specific raf inhibitor wo
Obese patients are prone to arterial hypertension, require more antihypertensive medications, and have an increased risk of treatment-resistant arterial hypertension. Obesity-induced neurohumoral activation appears to be involved. The association between obesity and hypertension shows large inter-individual variability, likely through genetic mechanisms. Obesity affects overall cardiovascular and
The measurement of the transport of scalar quantities within flows is oftentimes laborious, difficult or even unfeasible. On the other hand, velocity measurement techniques are very advanced and give high-resolution, high-fidelity experimental data. Hence, we explore the capabilities of a deep learning model to predict the scalar quantity, in our case temperature, from measured velocity data. Our
Medical education seemingly immune to discussions of gender. Study indicates gender perspective in teaching is lacking Maria Norstedt, Karen Davies Läkartidningen 2003:100;2056-62 This article builds upon qualitative interviews with teachers and students in the medical education at Lund university. The results found that a gender perspective is understood primarily in terms of the biological body.
Background: The COVID-19 pandemic has brought significant mental health challenges, particularly for vulnerable populations, including non-binary gender individuals. The COMET international study aimed to investigate specific risk factors for clinical depression or distress during the pandemic, also in these special populations. Methods: Chi-square tests were used for initial screening to select o
