Non-Abelian Solitons in N=4 Gauged Supergravity and Leading Order String Theory [PDF]
, 1997 We study static, spherically symmetric, and purely magnetic solutions of the N=4 gauged supergravity in four dimensions. A systematic analysis of the supersymmetry conditions reveals solutions which preserve 1/4 of the supersymmetries and are ...

Advanced Intelligent Systems, EarlyView.This review systematically analyzes deformable drones, including extendable, foldable, and tilting configurations, along with nature‐inspired flapping rotorcraft. By classifying deformation principles and structural mechanisms, design trade‐offs, functional capabilities, and future development potential are highlighted.

High-frequency backreaction for the Einstein equations under polarized $\mathbb U(1)$ symmetry
, 2017 Known examples in plane symmetry or Gowdy symmetry show that given a $1$-parameter family of solutions to the vacuum Einstein equations, it may have a weak limit which does not satisfy the vacuum equations, but instead has a non-trivial stress-energy ...

Disparity of turbinal bones in placental mammals
The Anatomical Record, EarlyView.Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Uterine arteriovenous malformation: a case report with proposal for pathogenesis
BMC Women's HealthUterine arteriovenous malformation (UAM) is a rare medical condition. Even though UAM can cause abnormal and life-threatening uterine hemorrhage, there is no consensus on the clinical guideline on its treatments, most likely due to its low incidence ...

The relationship between form and function of the carnivore mandible
The Anatomical Record, EarlyView.Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...
