Abstract – Introduction: Stroke is a leading cause of morbidity and mortality globally, with Africa bearing a disproportionately high burden of poor outcomes. In sub-Saharan Africa, acute stroke care remains inconsistent, with organized stroke units being either absent or rarely available, contributing to the high stroke mortality rates in the region. To address this issue, the Tanzania Stroke Pro
Diffraction gratings are among the most fundamental optical elements. They are essential in ultrafast optics for manipulating the spectral phase of coherent ultrashort light pulses in grating stretchers, compressors, and pulse shapers. In this work, we have exploited an effect associated with diffraction from a single grating, which can produce large amounts of spatially dependent GDD. Leveraging
This article presents a Luhmann-inspired theory of conflictualization, that is, how objects, relations, and societies come to be defined by the logic of conflict. This article presents a Galtung- and Luhmann-inspired theory of conflictualization, that is, how objects, relations, and societies come to be defined by the logic of conflict. The article conceptualizes conflictualization as a threefold
Intro: Population-based studies predominantly focused on carcinoma of the parotid gland (CPG) are rare. The study aims were to analyze the incidence of CPG and to assess treatment outcomes in relation to histopathology, preoperative diagnosis and adjuvant radiotherapy. Methods: A retrospective analysis was conducted on data from the Swedish Head and Neck Cancer Register (SweHNCR), including 1,018
Numerous studies show an association between military pressures and fiscal development, often based on cross-national correlations between wars and fiscal outcomes (e.g., tax ratios). However, investments in fiscal capacity may take time to yield higher tax revenues, obscuring the importance of factors that contributed to those investments. This article shifts attention from fiscal outcomes to the
The production yields of the orbitally excited charm-strange mesons (Formula presented) and (Formula presented) were measured for the first time in proton-proton (pp) collisions at a center-of-mass energy of (Formula presented) with the ALICE experiment at the LHC. The (Formula presented) and (Formula presented) mesons were measured at midrapidity ((Formula presented)) in minimum-bias and high-mul
Aim: Many populations of migratory birds are currently declining. Understanding space use throughout the entire annual cycle, as well as migratory connectivity (i.e., geographic linkage of individuals and populations across different stages of the annual cycle), can improve our ability to identify factors driving population declines and influencing extinction risk. The main objectives of our study
In multiple-planet systems, gravitational interactions of exoplanets could lead to transit timing variations (TTVs), whose amplitude becomes significantly enhanced when planets are in or near mean-motion resonances (MMRs), making them more easily detectable. In cases where both TTVs and radial velocity (RV) measurements are available, combined analysis can break degeneracies and provide robust pla
Background: Globally, undernutrition is responsible for over 3.5 million deaths among children under the age of 5. In Mozambique, it remains a major contributing factor to the high rates of child mortality and illness. Essential micronutrients like zinc, iron, and calcium play a vital role in healthy growth and development. However, their absorption is hindered by anti-nutrients such as phytates,
BackgroundThe Job Demand–Control–Support (JD-C-S) model evaluates how psychosocial work factors affect health and performance. We examined how demographics, job title, and experience influence demand, control, and support among Ghanaian pharmacy staff.MethodsA cross-sectional survey of pharmacy personnel from Tamale and Sagnerigu was conducted using the JD-C-S questionnaire. Demand and control ite
Word-of-Mouth (WoM) is a socially embedded process, and investors engage in social considerations to achieve self-motives. Investors attempt to share negative WoM (NWoM) to emotionally connect (self-affirm) to strengthen existing social ties following prior losses. In contrast, investors attempt to share positive WoM (PWoM) to self-enhance to attract others into developing new social ties. Thereby
BackgroundThis study aimed to investigate the exposure to perfluoroalkyl substances (PFAS) and cancer-related toxicity in workers in different Swedish industry sectors with exposures to hexavalent chromium (Cr(VI)).MethodsThe study consisted of 111 exposed workers and 72 controls. The exposed workers were performing manufacture/processing of metal products (n=55), working in steel production (n=31
CF-related diabetes (CFRD) is a prevalent comorbidity in people with Cystic Fibrosis (CF), significantly impacting morbidity and mortality rates. This review article critically evaluates the current understanding of CFRD molecular mechanisms, including the role of CFTR protein, oxidative stress, unfolded protein response (UPR) and intracellular communication. CFRD manifests from a complex interpla
Little is known about risk factors for central nervous system (CNS) relapse in mature T-cell and natural killer cell neoplasms (MTNKNs). We aimed to describe the clinical epidemiology of CNS relapse in patients with MTNKN and developed the CNS relapse In T-cell lymphoma Index (CITI) to predict patients at the highest risk of CNS relapse. We reviewed data from 135 patients with MTNKN and CNS relaps
BACKGROUND: This study aimed to explore the awareness, experiences, and beliefs of individuals with osteoarthritis (OA) regarding their healthcare management, along with assessing their overall satisfaction levels.METHODS: A cross-sectional online survey was conducted in Italy, Sweden, and Russia, rigorously developed based on OA international guidelines in collaboration with healthcare profession
A significant surface wettability transition from hydrophobicity to hydrophilicity after long-term operation is observed in graphite bipolar plates of a proton exchange membrane fuel cell (PEMFC). Extensive in-situ electrochemical characterization was performed to investigate the impact of bipolar plate wettability on the performance and durability of two PEMFCs (named “New cell” and “Old cell”),
Introduction: Ensuring access to clean and safe drinking water is crucial, especially in flood-prone regions where the water quality in dug wells can deteriorate due to various physicochemical factors. This research was aimed to measure the effectiveness of natural materials in improving water quality based on physicochemical parameters and to compare water quality before and after treatment in As
The energy and mass measurements of jets are crucial tasks for the Large Hadron Collider experiments. This paper presents a new calibration method to simultaneously calibrate these quantities for large-radius jets measured with the ATLAS detector using a deep neural network (DNN). To address the specificities of the calibration problem, special loss functions and training procedures are employed,
This thesis investigates superfluidity in exotic phases of ultracold bosonic gases, namely self-bound droplets, mixed bubbles, and dipolar supersolids. We investigated these systems analytically and numerically using an extended Gross-Pitaevskii and Bogoliubov-de Gennes formalism. The dissertation offers six chapters, providing the necessary derivations to build the required background and underst
