Titanium dioxide (TiO) is the most commonly used catalyst for fabricating commercial photocatalytic air purifier (AP) systems. The AP performance can be affected sensitively by the preparation conditions of filters and the physicochemical properties (e.g.

Chest radiographs from patients under 19 years old, collected between March and November 2021, were divided into test and exploring sets. A commercial adult-oriented AI software was utilized to detect lung lesions, including pneumothorax, consolidation, nodule, and pleural effusion, using a standard operating point of 15%.

While NAMs have been established for various industries, such as cosmetics, pesticides, and drugs, their applications in natural products (NPs) are lacking. NPs' complexity (multiple ingredients and structural differences from synthetic compounds) complicates NAM development.

Despite the recognized effectiveness of SGLT-2 inhibitors, there remains a paucity of research on the discontinuation of these medications. The objective of this study is to analyze the rate of discontinuation of SGLT-2 inhibitors, to evaluate the impact of discontinuation on the clinical outcome, and to identify the factors associated with discontinuation.

XRD measurements show clear evidence of structural phase transition (SPT) of the LCO thin films from the perovskite (PV) LaCoO to the brownmillerite (BM) LaCoO phases through the intermediate LaCoO phase at a temperature of 350 °C under high-vacuum conditions, ∼10 mbar. The reverse SPT from BM to PV phases is also found under ambient pressure (>100 mbar) of air near 100 °C.
