Solvent cage-escape dynamics of bimolecular photoredox products in solution has been investigated computationally through a combination of molecular dynamics simulations and quantum chemical calculations. The present work focuses on the photoinduced oxidation of the organic electron donor dimethylaniline (DMA) by a Fe(III) N-heterocyclic carbene photosensitizer (Fe(III)NHC+) in two different solve

We present a novel method for in-line acoustofluidic separation of cancer cells directly from whole blood. We report for the first time the observation that blood cells can self-organize when packed closely together in an acoustic field. We utilize this effect to enrich K-562 cancer cells and white blood cell subpopulations from whole blood at normal hematocrit levels. Further, we investigate the

Three different semiconductor nanowires are combined into a single optoelectronic artificial neuron. Our device provides a path towards low power computations with significantly reduced circuit footprint, thus addressing critical limitations in neuromorphic photonics. The false-coloured scanning electron micrograph shown in Figure 1a depicts the fabricated nanowire neuron. Two pin-doped InP nanowi

Photonics-based approaches to neuromorphic hardware offer advantages in speed and connectivity but often suffer from large device footprints.[1] Here, we present an ultra-compact artificial neuron built from semiconductor nanowires. A scanning electron micrograph of the nanowire device is presented in Figure 1a. Inside the dashed box, we show the neuron built from three III-V nanowires - two InP p

BACKGROUND: Diagnosing heart failure with preserved ejection fraction (HFpEF) remains challenging, particularly in older adults. While the Heart Failure Association (HFA)-PEFF and H2FPEF Scores offer structured diagnostic approaches, their clinical utility is still debated. This study aims to compare the diagnostic accuracy of HFpEF Scores versus inclusion criteria used in sodium-glucose cotranspo

Background: Around 95% of all websites selling medicines globally are illegal and contribute to the spread of substandard and falsified medicines. Hence, it is important to identify legal pharmacies when accessing medicines online. During 2022-2024, 250 million prescriptions were legally dispensed in Sweden, and 69% were prescribed in primary care. Pharmacists and general practitioners are key hea

Background: This study compared levels of physical activity (PA) and sedentary behavior (SB) in adults with and without chronic diseases or multimorbidity, acknowledging sociodemographic factors. Methods: A cross-sectional analysis was conducted with data from 27,890 participants (52% women), aged 50–64, from the Swedish CArdioPulmonary bioImage Study cohort. Over 1500 chronic diseases were includ

Isolated attosecond pulses are often generated via sub-optical-cycle polarization gating. This technique, based on the precise control of the time-dependent polarization of the infrared driver pulse, enables strong temporal confinement of the extreme ultraviolet (XUV) emission from high-order harmonic generation (HHG) in gases. In this work, we study the influence of pulse propagation between the

The aggregation of tau into amyloid fibrils is associated with Alzheimer’s disease (AD) and related tauopathies. Since different tauopathies are characterized by the formation of distinct tau fibril morphologies, it is important to combine the search of tau aggregation inhibitors with the development of in vitro tau aggregation assays that recapitulate aggregation as it may occur in the brain. Her

Methane dry reforming not only utilizes two potent greenhouse gases of methane and carbon dioxide, but also provides a valuable feedstock for the production of chemicals. However, this process has been heavily hindered by high operating temperature and coke formation with catalyst deactivation over the last century. Herein, we propose an approach whereby concentrated-solar catalytic methane dry re

Brain organoid technology has seen significant development in recent years. This self-organized, three-dimensional, organ-oriented brain tissue model can recapitulate the process of neurogenesis and consists of diverse cell types and cellular architecture. Transplanting brain organoids in vivo could be a potential tool from bench to clinical research and has been studied for many purposes. To inve

Background: Graft rejection (GR) is common complication after haploidentical hematopoietic cell transplantation (haplo-HCT). There are only a few studies describing the clinical presentation and potential risk factors of GR, and the optimal rescue strategy is not established. Objectives: To evaluate the cumulative incidence and potential risk factors for GR following haplo-HCT, and to compare surv

This study presents a cryogenic resonant radio frequency (RF) transmitter coil design for magnetic field generation that utilizes electromechanical switches to match and tune the resonance frequency with capacitor banks in situ. The design enables magnetic field generation at any frequency across a wide frequency range of 25-140 MHz (560% tuning range) while operating at 1.5 K. Magnetic field gene

BACKGROUND: The cross-sectional association between cerebral tissue oxygen saturation (SctO 2) and heart failure (HF) has been previously studied, but the prognostic significance of SctO 2 in HF remains uncertain. This study aimed to assess the role of SctO 2 as a risk factor for all-cause mortality and rehospitalisation, as well as to explore the cross-sectional association between physical activ

Stem cell sources capable of producing appropriate cells for replacement will be necessary for functional repair of the injured brain. Here, we have determined whether transcription factor programming of human embryonic stem (hES) cells can be used to generate layer-specific cortical neurons capable of integrating into the stroke-injured rat cortex. Human embryonic stem cells were programmed via o

The medical profession plays a crucial role in tackling the health impacts of climate change and in promoting a green transition of society and the health sector. Despite this, opportunities for action are still quite unknown within the profession, and no mandatory education is required in interns' or residents' education. Medical schools, on the contrary, both in Sweden (due to legislation) and a

Direct reprogramming of somatic cells into induced neurons (iNs) has become an attractive strategy for the generation of patient-specific neurons for disease modeling and regenerative neuroscience. To this end, adult human dermal fibroblasts (hDFs) present one of the most relevant cell sources. However, iNs generated from adult hDFs using two-dimensional cultures are difficult to maintain in vitro

We use a closed-loop algorithm to accurately program hafnium zirconium oxide (HZO) ferroelectric tunnel junctions (FTJs) to arbitrary chosen target conductance values. The key enabler is suppression of conductance growth. We have identified two different mechanisms contributing to the total conductance of FTJs. By controlling both, we demonstrated an up to threefold increase of the usable conducta

A memlumor is an innovative neuromorphic luminescent device with a state-dependent photoluminescence quantum yield (PLQY) designed for optical neuromorphic computing applications. Metal halide perovskite memlumors leverage charge trapping and photodoping to modulate the PLQY, making it dependent on the excitation light history. Here, we demonstrate the ability of perovskite memlumors to classify t
