Magnetic domain engineering in antiferromagnetic CuMnAs and Mn 2 Au

Antiferromagnetic materials hold potential for use in spintronic devices with fast operation frequencies and field robustness. Despite the rapid progress in proof-of-principle functionality in recent years, there has been a notable lack of understanding of antiferromagnetic domain formation and manipulation, which translates to either incomplete or nonscalable control of the magnetic order. Here,

Pathophysiology of syncope : current concepts and their development

Syncope is a symptom in which transient loss of consciousness occurs as a consequence of a self-limited, spontaneously terminating period of cerebral hypoperfusion. Many circulatory disturbances (e.g. brady- or tachyarrhythmias, reflex cardioinhibition-vasodepression-hypotension) may trigger a syncope or near-syncope episode, and identifying the cause(s) is often challenging. Some syncope may invo

A Geomagnetic Estimate of Heliospheric Modulation Potential over the Last 175 Years

Galactic cosmic rays (GCRs) interact with the Earth’s atmosphere to produce energetic neutrons and cosmogenic radionuclides, such as 14C. The atmosphere is partially shielded from the interstellar GCR spectrum by both the geomagnetic and solar magnetic fields. Solar shielding is often expressed as the heliospheric modulation potential ϕ, which consolidates information about the strength and struct

Complex fitting of 1H-MR spectra improves quantification precision independent of SNR and noise correlation

Quantification of in vivo proton magnetic resonance spectra (1H-MRS) still commonly involves evaluation of exclusively the real part of acquired spectral signals, but ignoring the information contained in the imaginary component may limit precise identification of individual metabolite contributions. Here, we assess quantification precision relative to SNR and noise correlation for both real and c

‘A Total Gamechanger’ : An Interpretative Phenomenological Analysis of Swedish Fathers’ Work-Family Experiences Since the COVID-19 Pandemic

Although Sweden is a top country for gender equality, there are disparities in domestic labor and parental leave use between men and women. The COVID-19 pandemic changed work-home life by increasing remote work. This study explored eight fathers’ work-family experiences in Sweden before, during and since the COVID-19 pandemic using interviews. Three group themes were developed using InterpretativeAlthough Sweden is a top country for gender equality, there are disparities in domestic labor and parental leave use between men and women.

Improving hydrogeological characterization using groundwater numerical models and multiple lines of evidence

Groundwater is Earth’s largest liquid freshwater resource. It is a significant component of the hydrological cycle and a buffer that sustainsrivers and freshwater-dependent ecosystems during droughts. Approximately half of the world’s population depends on groundwater fordrinking water, food, and hygiene. It is used extensively in agricultural irrigation, food production and for industrial process

Last general practitioner consultation during the final month of life: a national medical record review of suicides in Sweden

ObjectivesIndividuals who die by suicide often consult their general practitioners (GPs) in their final weeks of life. The aim of this study was to gain a deeper knowledge of the clinical characteristics and GP assessments and treatments among individuals who consulted their GPs during the month preceding suicide. Further, we compared these features in those with and without contact with psychiatr

Starch in Food : Structure, Function, and Applications

Starch in Food: Structure, Function and Applications, Third Edition is now fully updated with eleven new chapters covering "hot" areas for starch applications, such as starch-based pickering emulsifiers, starch for structuring gluten-free bread products, and starch microspheres for encapsulation of probiotic bacteria. Sections illustrate how plant starch can be analyzed and modified, including cha

Analysis of starch molecular structure, molar mass, and size

Starch, a vital food ingredient from diverse sources, possesses a complex molecular structure with amylopectin and amylose polymers. The polymers vary greatly in size, molar mass, and branching, often displaying very polydisperse size distributions and considerable among ultra-high molar mass polymers. This renders the analysis and characterization of starch polymers a challenging task. This chapt

Starch-based food emulsifiers

Starch which has been modified with octenyl succinic anhydride (OSA) is an efficient emulsifier for food emulsions. The presence of the OSA groups renders the starch polymers surface active and allows for their adsorption at the oil-water interface. Due to the large size of the starch polymers, adsorbed starch offers efficient steric stabilization of emulsions. Stability is achieved also at low pH

High-field/high-frequency electron spin resonances of Fe-doped β-Ga2 O3 by terahertz generalized ellipsometry : Monoclinic symmetry effects

We demonstrate detection and measurement of electron paramagnetic spin resonances (EPR) of iron defects in β-Ga2O3 utilizing generalized ellipsometry at frequencies between 110 and 170 GHz. The experiments are performed on an Fe-doped single crystal in a free-beam configuration in reflection at 45∘ and magnetic fields between 3 and 7 T. In contrast with low-field, low-frequency EPR measurements, w

A story about effects of Microwaves from Mobile-phones, and Alzheimer's disease

A team of clinical researchers at Lund University found that electromagnetic radiation, such as that used in GSM-900 mobile telephones, at low non-thermal power values (<2 W/kg), causes users' blood albumin to leak through the blood-brain barrier "BBB" into in the brain tissue.

But where's the body? Bodies, time, money, and the political economy of post-pandemic field research

Since the pandemic, field work has been transformed by shifts in the political economy affecting the material conditions underpinning research. In this research note, a research team considers their challenges and learning in completing field studies conducted in 2022, including intensified strains on time, money, researchers’ bodies, and risks associated with illness and infection spread. We argu

Connectivity and climate influence diversity–stability relationships across spatial scales in European butterfly metacommunities

Aim: Anthropogenic-driven biodiversity loss can impact ecosystem stability. However, most studies have only evaluated the diversity–stability relationship at the local scale and we do not fully understand which factors stabilize animal populations and communities across scales. Here, we investigate the role of species dispersal ability, climate, spatial distance and different facets of biodiversit
