The decay mode D^0 -> K^0 \bar{K^0} has no factorizable contribution. We calculate the nonfactorizable chiral loop contributions of order O(p^3)and then we use a heavy-light type chiral quark model to calculate nonfactorizable tree level terms, also of order O(p^3), proportional to the gluon condensate. Calculated chiral loops and the gluon condensate contributions are of the same order of magnitude as the experimental amplitude.
arxiv.orgSpinosad is a naturally derived insecticide obtained from a soil-dwelling bacterium and is widely used against various agricultural and public-health pests. Although resistance to spinosad has been reported in several pest groups-including thrips, fruit flies, beetles, lepidopterans, and even mosquitoes-no study to date has evaluated its resistance status in the house fly,
www.ncbi.nlm.nih.govCancer antigen 19-9 (CA19-9) is used to assess treatment response among patients with pancreatic ductal adenocarcinoma (PDAC); however, nearly 30% of patients with PDAC do not produce elevated CA19-9.

www.ncbi.nlm.nih.govArtificial intelligence (AI) is transforming healthcare, demanding reevaluation of medical education. China039;s "New Medical Education" initiative urgently requires a standardized AI literacy framework for medical students to address fragmented standards, rapid technological evolution, and insufficient localized ethical norms.

www.ncbi.nlm.nih.govThe American Society of Anaesthesiologists Physical Status (ASA-PS) classification system is the most widely used tool for estimating perioperative risk. Despite its widespread application, the ASA-PS is based solely on the subjective assessment of the patient’s clinical condition and comorbidities, which leads to considerable inter-rater variability. The aim of this study was to investigate interprofessional differences in ASA-PS scoring between surgeons and anaesthesiologists.
www.ncbi.nlm.nih.govScreening morning serum cortisol is used to select patients for ACTH stimulation testing to diagnose adrenal insufficiency (AI) but may be affected by pre-analytical factors. Careful consideration to discontinue confounding medications beforehand may preclude the need for subsequent stimulation testing.
