Seven species of Dasyproctus Lepeletier & Brullé, 1835 (Hymenoptera: Crabronidae) are recorded from North Vietnam. Of these, D. vietnamensis and D. longi are new species, and D. idrieus (Cameron) and D. pentheri Leclercq are recorded for the first time from the country. Keys to both sexes of Dasyproctus from North Vietnam based on morphological characters are given, and new distributional records are also presented.

Introduction: Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder among children with attention deficit hyperactivity disorder (ADHD). This study aims to determine the prevalence of OSA in children with ADHD, compare the differences in clinical characteristics between children with ADHD-OSA and those without OSA (ADHD-nonOSA), and to identify the correlation between OSA and ADHD in children.
Methods: This cross-sectional descriptive study was conducted on 524 children with ADHD, aged 6-12 years, at the Vietnam National Children's Hospital from October 2022 to September 2023.

(±)-Melichuniiones A and B (1 and 2), two novel enantiomeric pairs of lignan-phloroglucinol hybrids with an unprecedented beadlike core were isolated from the leaves of , together with new analogues 3-6. Compounds 1 and 2 possess a unique dispiro [furan-2,5'-cyclopenta[]furan-2',3''-furan] 5/5/5/5 tetracyclic skeleton. Their structures were established by extensive spectroscopic analyses, single crystal X-ray diffraction, and electronic circular dichroism (ECD) calculations.

African swine fever (ASF) is considered as one of the most threatening diseases for the pig farming industry all over the world. Due to the lack of an effective vaccine, organized farms and backyard rearing must strictly enforce control measures in order to combat the disease. The present report describes the ASF epidemic in a piggery in Uttar Pradesh state, India.

In this work, Ge vacancies and doping with transition metals (Mn and Fe) are proposed to modulate the electronic and magnetic properties of GeP monolayers. A pristine GeP monolayer is a non-magnetic two-dimensional (2D) material, exhibiting indirect gap semiconductor behavior with an energy gap of 1.34(2.

Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive analytical technique with excellent molecular specificity. However, separate pristine nanoparticles produce relatively weak Raman signals. It is necessary to focus on increasing the "hot-spot" density generated at the nanogaps between the adjacent nanoparticles (second-generation SERS hotspot), thus significantly boosting the Raman signal by creating an electromagnetic field.
