We report an efficient, general methodology for producing high-surface area metal oxide nanomaterials a vast range of oxides, including at least one nanomaterial from nearly every transition and semi-metal group in the periodic table (groups 3-4 6-15) as well several lanthanide (see ). The method requires only 2-3 simple steps; hydrated salt (usually nitrate or chloride salt) is ground with bicarbonate NH4HCO3) 10-30 minutes to form precursor that then either untreated rinsed before being...

Chiral nanoparticles are one of the research hotspots in field materials science, chemistry, and biology. Understanding controlling chirality is key step toward their use, but origin nanoparticles' its determinative factor not well understood. In this work, we studied gold (AuNPs) prepared through conventional citrate reduction method. Unexpectedly, it was found that small AuNPs (∼13 nm) exhibited opposite to large (>30 nm). The revealed by comparing crystal structure between AuNPs. It...

Abstract Objective This study assesses the influence of hyperkalemia on both disease severity and risk mortality among patients admitted to emergency room. Methods retrospective observational utilized data from Chinese Emergency Triage Assessment Treatment database (CETAT, version 2.0), which was designed evaluate optimize management strategies for room (ER) patients. Patients were systematically categorized based serum potassium levels. Relationships between levels, mortality, illness then...

Melanoma segmentation in Whole Slide Images (WSIs) is useful for prognosis and the measurement of crucial prognostic factors such as Breslow depth primary invasive tumor size. In this paper, we present a novel approach that uses Segment Anything Model (SAM) automatic melanoma microscopy slide images. Our method employs an initial semantic model to generate preliminary masks are then used prompt SAM. We design dynamic prompting strategy combination centroid grid prompts achieve optimal...

In the face of emerging new types crimes in digital economy era, criminal law, as a fallback link legal regulatory system, should respond accordingly. Therefore, weakening principle legality and punishments brought about by operation not be understood an absolute negative value, re examined conjunction with logic operation. At present, regulation data itself China's law is still limited to carrier material entity - traditional computer information systems. The recognition interests remains...
