Emergence of Weyl fermions by ferrimagnetism in a noncentrosymmetric magnetic Weyl semimetal

Condensed matter physics has often provided a platform for investigating the interplay between particles and fields in cases that have not been observed in high-energy physics. Here, using angle-resolved photoemission spectroscopy, we provide an example of this by visualizing the electronic structure of a noncentrosymmetric magnetic Weyl semimetal candidate NdAlSi in both the paramagnetic and ferr

Observation of flow angle and flow magnitude fluctuations in Pb-Pb collisions at sNN =5.02 TeV at the CERN Large Hadron Collider

This Letter reports on the first measurements of transverse momentum dependent flow angle ψn and flow magnitude vn fluctuations determined using new four-particle correlators. The measurements are performed for various centralities in Pb-Pb collisions at a center-of-mass energy per nucleon pair of sNN = 5.02 TeV with ALICE at the CERN Large Hadron Collider. Both flow angle and flow magnitude fluct

A New Technique for Pelvic and Vaginal Reconstruction in Abdominoperineal Rectal Excision : Combination of Gluteus Maximus Flap and Fasciocutaneous Flap

Resection of advanced rectal cancer might result in significant tissue loss, including pelvic floor and parts of the vaginal wall. Pelvic floor reconstruction using a musculocutaneous flap offers optimized healing abilities and the possibility of vaginal reconstruction. In Skåne University Hospital, two different flap techniques are used to reconstruct the perineum: the vertical rectus abdominis m

Tumour origin, diagnostic accuracy and histopathological evaluation in patients with periampullary cancer : nationwide cohort study

Background: The prevalence of different periampullary cancers (pancreatic ductal adenocarcinoma, distal cholangiocarcinoma, ampullary cancer and duodenal cancer) is heterogeneous in the literature. During the 2010s, a standardized histopathological protocol for pancreatoduodenectomy specimens based on axial slicing was adopted in Sweden. The present study sought to provide information about periam

China 6 EGR gasoline vehicles without a GPF may struggle to meet the potential SPN10 limit

Particles larger than 10 nm from engine exhaust are gaining global concerns. In light of this, to investigate how EGR affects gasoline vehicle SPN10 (solid particles larger than 10 nm) emissions, seven gasoline vehicles (hybrid or conventional) were studied experimentally. The results revealed that EGR vehicles risk failing the current limit (6 * 1011 #/km) more than those without EGR if the cut-o

Comparing different techniques for obtaining molecular size distributions of glycogen

Glycogen is a hyperbranched glucose polymer, serving as a major energy reservoir in animals. Characterization of the size distributions of complex branched polysaccharides helps in the understanding of their structural and functional properties. This study compared the effectiveness of various techniques in analyzing glycogen size distributions, namely size-separation-based techniques (size exclus

Updating the Definition of Cancer

Most definitions of cancer broadly conform to the current NCI definition: "Cancer is a disease in which some of the body's cells grow uncontrollably and spread to other parts of the body." These definitions tend to describe what cancer "looks like" or "does" but do not describe what cancer "is" or "has become." While reflecting past insights, current definitions have not kept pace with the underst

The Black Swan problem : The role of capital, liquidity and operating flexibility

How firms cope with tail risk is an under-researched problem in the literature on corporate risk management. This paper presents stylized facts on the nature of revenue shocks based on 65 years worth of Compustat data. We define a Black Swan as an unexpected year-on-year drop in revenue between 30%–90%. The rate of Black Swans has increased markedly since the 1970's and there are more pronounced c

East Asian Anxieties: Child-centered Relatedness and Parents’ Care Work in Education in Singapore

The size and ‘quality’ of the population are issues of major concern in contemporary East Asia, as fertility rates are falling and competitiveness increasingly centers on ‘a fitting’ human capital. While Singapore is located in Southeast Asia geographically speaking, it is culturally linked to East Asia in terms of its heritage of Confucianism and the Chinese language.

Expanding the lens on child-centered relatedness and parents’ care work in education: reflections from fieldwork in Singapore

This paper aims to initiate a discussion on the meanings and manifestations of child-centered relatedness, with a particular focus on parents’ educational care work and how parents navigate sentiments of uncertainty and risk in relation to their children’s future. By drawing on examples from ethnographic fieldwork in East Asia, I hope to contribute to expanding the lens on the moral and emotional

Investigation of K+K- interactions via femtoscopy in Pb-Pb collisions at sNN =2.76 TeV at the CERN Large Hadron Collider

Femtoscopic correlations of nonidentical charged kaons (K+K-) are studied in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon collision sNN=2.76 TeV by ALICE at the CERN Large Hadron Collider. One-dimensional K+K- correlation functions are analyzed in three centrality classes and eight intervals of particle-pair transverse momentum. The Lednický and Luboshitz interaction model used

Osäkerhet i beslut om placeringar av barn och unga

Hur går det till när besluts fattas om huruvida, när och vart ett barn eller en ungdom ska placeras i samhällsvård och vad händer med detta beslutsfattande när ärendetrycket ökar på organisationen? Den brittiske barnavårdsforskaren Nigel Parton (1998), bland andra, har hävdat att när trycket ökar och resurser blir färre inom människobehandlande organisationer som Socialtjänsten, är en vanlig reakt

Identifying secreted biomarkers of dopaminergic ventral midbrain progenitor cells

BackgroundVentral midbrain (VM) dopaminergic progenitor cells derived from human pluripotent stem cells have the potential to replace endogenously lost dopamine neurons and are currently in preclinical and clinical development for treatment of Parkinson’s Disease (PD). However, one main challenge in the quality control of the cells is that rostral and caudal VM progenitors are extremely similar tr

Ultrasound standing wave spatial patterning of human umbilical vein endothelial cells for 3D micro-vascular networks formation

Generating functional and perfusable micro-vascular networks is an important goal for the fabrication of large and three-dimensional tissues. Up to now, the fabrication of micro-vascular networks is a complicated multitask involving several different factors such as time consuming, cells survival, micro-diameter vasculature and strict alignment. Here, we propose a technique combining multi-materia

The role of digital municipal currencies in advancing a new form of progressive welfare policies : The case of the State of Rio de Janeiro

At the onset of the pandemic, Brazil’s Federal government approved an emergency basic income to be transferred to a variety of groups that had not earlier received any of the established welfare programs. Its implementation was however riddled with challenges. With a large informal economy, many Brazilian citizens were missing from the Federal Government’s registry and, even if registered, many di

A starch- and sucrose-reduced diet may lead to improvement of intestinal and extraintestinal symptoms in more conditions than irritable bowel syndrome and congenital sucrase-isomaltase deficiency

Objectives: A starch- and sucrose-reduced diet has been found to improve gastrointestinal and extraintestinal symptoms in irritable bowel syndrome, as well as reduce weight and improve psychological well-being. Our hypothesis was that a starch- and sucrose-reduced diet would also be beneficial in other conditions with similar symptoms. The aim of the present research letter was to describe the rol

Anaerobic fixed-target serial crystallography using sandwiched silicon nitride membranes

In recent years, the emergence of serial crystallography, initially pioneered at X-ray free-electron lasers (XFELs), has sparked a growing interest in collecting macromolecular crystallographic data at room temperature. Various fixed-target serial crystallography techniques have been developed, ranging from commercially available chips to in-house designs implemented at different synchrotron facil

Magnitude of extended high frequency hearing loss associated with auditory related tinnitus distress, when controlling for magnitude of hearing loss at standard frequenciesa)

Impaired thresholds at extended high frequencies (EHF) are tightly linked to the prevalence of tinnitus, but little is known about how EHF status relates to tinnitus characteristics. In the present study, 93 individuals with tinnitus underwent standard (from 0.125 to 8 kHz) and EHF (from 10 to 16 kHz) audiometry and indicated their degree of tinnitus distress by completing the tinnitus functional
