The microhydration of rock salt (NaCl) molecules was investigated theoretically by density‐functional theory and force field calculations and experimentally by high‐resolution Penning ionization electron spectroscopy...

We compare the Technicolor Dawn cosmological simulations with recent observations of galactic nebular line emission during the Epoch of Reionization, providing stringent tests of the predicted ionization and metal enrich...

A 12-day-old full-term (FT) male presented with one day of diarrhea and respiratory distress. The exam was notable for hypothermia, tachycardia, and hypoxemia. Initial bloodwork showed leukopenia (3,400 cells/uL, absolut...

Context. Silver is a key tracer of the weak r-process in late-type stars. However, when the assumption of local thermodynamic equilibrium is relaxed, accurate abundance determinations become even more sensitive to comple...

Abstract High-electron-mobility transistors (HEMTs) based on wide bandgap (WBG) materials like gallium nitride (GaN) are vital for next-generation power electronics and high-frequency applications, offering high breakdow...

“Cagaita” is the fruit of the “cagaiteira” (Eugenia dysenterica), a native fruit tree of the Myrtaceae family, found in the Brazilian “Cerrado”. This fruit is a rich source in nutrients and bioactive compound...

This study investigated the potential of polyvinylpyrrolidone-grafted graphene (PGR) for secondary reinforcement of SBS and microwave-activated crumb rubber (ACR) modified asphalt, aiming to clarify the underlying mechan...

To enhance the total output energy and power of energetic materials, plasma that generated by electrically exploded metal wires was employed to initiate the detonation of energetic materials, thereby achieving the couple...

Chlorella micro algae strains offer sustainable biomass feedstocks in biofuel production because of their resilience, diversity, high adaptability to environmental stresses, flexible cultivation alternatives and high bio...

Parkinson’s disease (PD) is characterized by profound metabolic disturbances in the brain, yet how these alterations vary across brain regions and respond to neuroprotective intervention remains poorly understood. Here...

Abstract Background Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) protein profiling has emerged over the last decade as a method of choice for species identification of many ...

Abstract Purpose Exhaled gas analysis is a non-invasive and straightforward method for the diagnosis of lung cancer. This study aimed to assess whether characteristic compounds in exhaled gas can serve as specific diagno...

This study presents the results of a multicentre external dosimetry audit conducted as part of the PROTECT trial, involving nine European radiotherapy centres delivering proton and photon treatments. A dosimetry equipmen...

Abstract Rapid identification of bacterial species from patient samples is crucial for clinical decision‐making. In severe infections, such as bloodstream infections, the early start of an effective treatment is direct...

Neonatal sepsis has remained a foremost cause of morbidity and mortality globally, specifically in low- and middle-income countries. The neonatal period, which spans the first 28 days of life, has the highest lifetime ri...

Abstract This study reports the green biosynthesis of bioactive selenium nanoparticles using Catharanthus roseus extract as a reducing and stabilizing agent. Liquid chromatography–electrospray ionization tandem mass sp...

Abstract Quantifying luminescence signal resetting of sand grains in turbid waters is essential for both sediment dating and tracing, yet direct measurement under natural subaqueous conditions remain scarce. Here, we pre...

Abstract Background Robinsoniella peoriensis, an anaerobic, Gram-positive bacillus within the phylum Firmicutes and family Lachnospiraceae, is a putative commensal anaerobe of the human gut and an infrequent cause of opp...

IntroductionMyroides odoratimimus is a Gram-negative opportunistic pathogen primarily affecting immunocompromised individuals. However, its resistance characteristics and therapeutic response in cancer patients remain po...
