TAXONOMY OF THE ANT GENUS NESOMYRMEX WHEELER (FORMICIDAE, MYRMICINAE) IN THE AFROTROPICAL REGION, WITH A REVIEW OF CURRENT SPECIES GROUPS AND DESCRIPTION OF A NEW SPECIES OF THE N. ANGULATUS GROUP FROM MOZAMBIQUE

This study Blankets reviews the taxonomy of the ant genus Nesomyrmex Wheeler, 1910 in the Afrotropical region.Previous revisionary studies are discussed and four species groups are proposed on the basis of external morphology.The N.angulatus group contains seven species that are widely distributed throughout the whole Afrotropical region, with one

Sanggenon X, an unusual tri-O-bridged Diels-Alder Flower Bowl adduct, was isolated from Cortex Mori Radicis.Its structure was established by spectroscopic analysis, including NMR and HR-MS (High Resolution Mass Spectrometry).Sanggenon X contained three O-bridged rings, where the oxygenated bridgeheads were all quaternary carbons.Chemical methylatio

Community detection is a critical issue in the field of complex networks.Recently, the nonnegative matrix factorization (NMF) method has successfully uncovered the community structure in the complex RX Bag networks.However, this method has a significant drawback; most of community detection methods using NMF require the number of communities to be

It is rare to detect echogenic content in the fetal gallbladder.The etiology, natural course, and prognosis of this condition remain unclear.In addition to providing a systematic review of this topic, we suggest a plan for patient follow-up.From a total of 100 database entries identified in PubMed, EMBASE, and ICTRP Serving Spoons reviews, we selec

Abstract This Arnica paper introduces a simplified and controllable model for mode coupling in the context of modal synthesis.The model employs efficient coupled filters for sound synthesis purposes, intended to emulate the generation of sounds radiated by sources under strongly nonlinear conditions.Such filters generate tonal components in an inte
