Enhanced Fluorescence Resonance Energy Transfer in G-Protein-Coupled Receptor Probes on Nanocoated Microscopy Coverslips

The G-protein-coupled receptor (GPCR) superfamily mediates cellular responses and communication across cellular membranes and is the largest known class of molecular targets with proven therapeutic value. For probing conformational changes of GPCRs and others in a live cell setting, fluorescence resonance energy transfer (FRET) is usually the method of choice. FRET probes often require careful lab

High-speed optical diagnostics of misfire limits in a spark-ignited heavy-duty hydrogen engine

This study investigates the ignitability of hydrogen in an optical heavy-duty SI engine. While the ignition energy of hydrogen is exceptionally low, the high load and lean mixtures used in heavy-duty hydrogen engines lead to a high gas density, resulting in a much higher breakdown voltage than in light-duty SI engines. Spark plug wear is a concern, so there is a need to minimise the spark energy w

Unfolding the Mystery of Autoimmunity : The Environmental Determinants of Diabetes in the Young (TEDDY) Study

In 2025, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) at the National Institutes of Health celebrates 75 years of leadership in diabetes research. The NIDDK serves people of the U.S. affected by or at risk for many chronic diseases, including diabetes and other endocrine, metabolic, and digestive disorders, by funding innovative research to develop better treatment

Ukrainian refugees and welfare deservingness: a comparative study of UK government discussions around the 2022 Ukraine Conflict and 2015 Migrant Crisis

Recent years witnessed mass migration towards Europe, from Russia's 2022 invasion of Ukraine and the 2015 Migrant Crisis linked to war in Syria. This article explores UK government discussion around these two significant crises, focussing on the challenges they present and the portrayal of refugees. It asks how far ministers' language differentiated between Ukrainians and Syrians regarding welfare

Stabilized scattering matrix formulation for 2D periodic multilayer dielectrics

This paper proposes an alternative semi-analytical Fourier modal method adapted for general periodic anisotropic gratings made of dielectrics with moderate to low index profiles corresponding to materials ranging from conventional dielectric 3D printing materials to ceramic materials. The proposed method is closely related to classical Rigorous Coupled-Wave Analysis built on scattering matrices, h

Does new public management repel talent? : findings from a choice experiment among German researchers

This paper analyses the effects of new public management governance on academics’ job choices. Based on a choice experiment carried out with faculty from a sample of Germany’s leading technical universities, we find that working environments characterized by varying levels of administrative burdens and high expectations concerning third-party funding acquisition are detrimental to self-actualizati

Cyanobacterial Argonautes and Cas4 family nucleases cooperate to interfere with invading DNA

Prokaryotic Argonaute proteins (pAgos) from the long-A clade are stand-alone immune systems that use small interfering DNA (siDNA) guides to recognize and cleave invading plasmid and virus DNA. Certain long-A pAgos are co-encoded with accessory proteins with unknown functions. Here, we show that cyanobacterial long-A pAgos act in conjunction with Argonaute-associated Cas4 family enzyme 1 (ACE1). S

Modelling light-dark regime influence on the carbon-nitrogen metabolism in a unicellular diazotrophic cyanobacterium

We propose a dynamical model depicting nitrogen (N2) fixation (diazotrophy) in a unicellular cyanobacterium, Crocosphaera watsonii, grown under light limitation and obligate diazotrophy. In this model, intracellular carbon and nitrogen are both divided into a structual pool and a storage pool. An internal pool that explicitly describes the nitrogenase enzyme is also added. The model is successfull

Bacteroides maternus sp. nov., a novel species isolated from human faeces

A novel bacterial strain, MSB163, was isolated from the stool sample of a healthy mother, 4 weeks after giving birth via vaginal delivery. Taxonomic identification tools revealed that MSB163 belongs to the genus Bacteroides, but it is distinct from any currently known species. The closest related species is Bacteroides cellulosilyticus strain BFG- 250, with an average nucleotide identity (fastANI)

Influence of feeding habit and duration on infant gut microbiome – a 6 month pilot study

While the importance of breastfeeding on the developing infant gut microbiota has been established, few studies have compared the effect of breastfeeding duration on infant gut microbiota development. In this pilot study, we included 23 infants, divided into 4 groups to compare the effect of breastfeeding duration for first 4 (BreastFed_4) or 8 weeks (BreastFed_8) compared to exclusive breast

What impact did the process of Romanization have on the landscapes and territories of ancient Hispania? This book examines the transformations of Baetica through a rigorous study of Western Sierra Morena and the Lands of Antequera, two key regions for understanding this historical period.The research adopts an innovative perspective that integrates spatial analysis and landscape study to examine t

Clinical Relevance of Contact Allergy to Gold Sodium Thiosulphate in Fibromyalgia

Fibromyalgia is a chronic syndrome characterized by pain, fatigue, and cognitive disturbances. The increased prevalence of contact allergy to gold in individuals with fibromyalgia when compared with the general population has previously been described. Gold contact allergy can manifest as a systemic contact dermatitis, with cutaneous and extracutaneous manifestations presenting upon systemic admin

Diffusion MRI with double diffusion encoding and variable mixing times disentangles water exchange from transient kurtosis

Double diffusion encoding (DDE) makes diffusion MRI sensitive to a wide range of microstructural features, and the acquired data can be analysed using different approaches. Correlation tensor imaging (CTI) uses DDE to resolve three components of the diffusional kurtosis: isotropic, anisotropic, and microscopic kurtosis. The microscopic kurtosis is estimated from the contrast between single diffusi

Förändringar i tillförselpotential av långsiktigt hållbar skogsbiomassa

Bioenergi spelar idag en stor roll i det svenska energisystemet ur klimat- och energisäkerhetssynpunkt men vilken roll kan inhemsk bioenergi komma att spela framöver för att Sverige ska bli ett fossilfritt samhälle med nettonollutsläpp 2050? Syftet med denna rapport är att utifrån olika perspektiv beskriva hur tillförseln av inhemska skogsbaserade biobränslen kan komma att förändras under perioden

Integrated Model for Simulation and Regulation of Basin Water Resources Considering Water Quantity and Quality and Its Application

With the rapid process of urbanization, water conflicts between different water use industries and areas are increasing. Therefore, China has implemented the three-cordons system of water resources management since 2012, when how to make more reasonable regulation of water resources became an urgent problem in most areas of China. In this study, taking the Yuanhe River Basin as an example, an inte
