Improved modeling and bounds for NQR spectroscopy signals

Nuclear Quadrupole Resonance (NQR) is a method of de- tection and unique characterization of compounds containing quadrupolar nuclei, commonly found in many forms of ex- plosives, narcotics, and medicines. Typically, multi-pulse sequences are used to acquire the NQR signal, allowing the resulting signal to be well modeled as a sum of exponentially damped sinusoidal echoes. In this paper, we improv

Systematic trends in beta-delayed particle emitting nuclei: The case of beta p alpha emission from Mg-21

We have observed beta(+)-delayed alpha and p alpha emission from the proton-rich nucleus Mg-21 produced at the ISOLDE facility at CERN. The assignments were cross-checked with a time distribution analysis. This is the third identified case of beta p alpha emission. We discuss the systematic of beta-delayed particle emission decays, show that our observed decays fit naturally into the existing patt

First Trimester Urine and Serum Metabolomics for Prediction of Preeclampsia and Gestational Hypertension: A Prospective Screening Study.

Hypertensive disorders of pregnancy, including preeclampsia, are major contributors to maternal morbidity. The goal of this study was to evaluate the potential of metabolomics to predict preeclampsia and gestational hypertension from urine and serum samples in early pregnancy, and elucidate the metabolic changes related to the diseases. Metabolic profiles were obtained by nuclear magnetic resonanc

Structural and magnetic properties of MnAs/GaAs ferromagnetic semiconductor nanocomposite material

Self-organized (Ga,Mn)As nanoclusters, embedded in GaAs and formed during thermal annealing of Ga1-xMnxAs layer at 500 degrees C or 600 degrees C, were studied using Transmission Electron Microscopy (TEM) and Magnetic Force Microscopy (MFM). We found that 10-20 nm large NiAs-type hexagonal MnAs nanocrystals gave magnetic contrast in MFM images, whereas smaller zinc-blende nanoinclusions were not v

3-D impedance networks simulate complex resistivity spectra of sand-pyrite-water mixtures

Characterizing ore deposits or mining dumps in terms of mineral content and grain size remains a challenge. Since the 1950s the induced polarization (IP) method has been successfully applied in ore prospecting. However, reliably interpreting field survey data requires comprehensive laboratory studies to establish a link between the IP parameters from empirical or phenomenological models and the typ

A systematic meta-review: the relationship between forest structures and biodiversity in deciduous forests.

Human activities in deciduous forests over the past centuries have influenced associated species. To reduce extinction risks and mitigate population declines, there is growing interest in forest conservation and restoration, including initiatives by the European Union (EU). For resulting restoration and conservation practices to succeed, it is essential to know which forest characteristics promote

Genombrott i fuktmätning : Ingjutningsbara och trådlösa RF-prober för betong

Mätning av relativ fuktighet, RF, i betong har tagit ett stort steg framåt med hjälp av trådlösa RF-prober som kan gjutas in direkt från start. I ett nyligen avslutat projekt vid avdelning Byggnadsmaterial vid Lunds tekniska högskola har ett mätsystem för RF i betong utvärderats. En av de största utmaningarna var att säkerställa att proberna klarar ingjutning och att de ger tillförlitliga mätninga

Renovera för hela livet. Det är inte bara en fråga för fastighetsägare.

Bostadskrisen slår mot alla generationer – men lösningarna måste vara långsiktiga och inkludera de behov äldre människor har. Det skriver fyra forskare som är verksamma vid institutionen för hälsovetenskaper vid Lunds universitet och tillhörforskningscentret CASE, Centre for Ageing and Supportive Environments.

Global Distribution and Local Variation of Pre-Rain Green-Up in Tropical Dryland

Pre-rain green-up is a distinctive phenological phenomenon observed in arid and semi-arid regions, featuring the sprouting of plants before the onset of the rainy season. This phenomenon indicates the intricate controls of vegetation phenology other than precipitation, yet its global distribution patterns and underlying causes remain unclear. In this study, we used remotely sensed phenology and ra

Resilience of primary healthcare facilities : Experiences from 16 European countries during the COVID-19 pandemic. A mixed-methods study conducted by EURIPA

Background. The role of primary healthcare (PHC) during a pandemic varies across European countries. The coronavirus disease 2019 (COVID-19) pandemic has altered the working practices of family medicine doctors and impacted the resilience of healthcare systems. Objectives. This study aimed to examine European healthcare system responses to the pandemic, focusing on rural and urban differences. Mat

Antisense-mediated regulation of exon usage in the elastic spring region of Titin modulates sarcomere function

Aims Alternative splicing of Titin (TTN) I-band exons produce protein isoforms with variable size and elasticity, but the mechanisms whereby TTN splice factors regulate exon usage and thereby determining cardiomyocyte passive stiffness and diastolic function, is not well understood. Non-coding RNA transcripts from the antisense strand of protein-coding genes have been shown to regulate alternative

TinyFoA : Memory Efficient Forward-Only Algorithm for On-Device Learning

Forward-only algorithms offer a promising memory-efficient alternative to Backpropagation (BP) for on-device training. However, state-of-the-art forward-only algorithms, e.g., Forward-Forward (FF), still require a substantial amount of memory during the training process, often exceeding the limits of mobile edge and Internet of Things (IoT) devices. At the same time, existing memory-optimization t

X-ray crystallographic and hydrogen deuterium exchange studies confirm alternate kinetic models for homolog insulin monomers

Despite the crucial role of various insulin analogs in achieving satisfactory glycemic control, a comprehensive understanding of their in-solution dynamic mechanisms still holds the potential to further optimize rapid insulin analogs, thus significantly improving the well-being of individuals with Type 1 Diabetes. Here, we employed hydrogen-deuterium exchange mass spectrometry to decipher the mole

Marknadsföring, människor och interaktion

Marknadsföring är så mycket mer än strategier, marknadsundersökningar och reklamkampanjer. Den uppstår i det dagliga samspelet mellan människor. I Marknadsföring, människor och interaktion får vi ett alternativt perspektiv på marknadsföring, bortom den traditionella marketing management-logiken. Genom att utgå från symbolisk interaktionism synliggör författarna hur marknader, konsumenter, produkte
