On the branes behind scale-separated AdS3 flux vacua
A bstract We investigate the brane origin of supersymmetric and scale-separated AdS 3 flux vacua arising in a class of type IIB orientifold reductions with G 2 -structure. First, using the effective three-dimensional supergravity together with explicit uplift formulae, we trace b...

Ligation of the canine mesovarium with a resorbable self-locking device: a multicentre study
Abstract Background Haemorrhage from the ovarian pedicle is a known complication at removal of ovaries in dogs. A resorbable self-locking device designed for surgical ligation was previously developed, aimed to keep the advantage of a self-locking loop at ligation and avoid the c...

An Alternative Test to Evaluate the Assistance Provided by Back-Support Exoskeletons: A Pilot Study
OCCUPATIONAL APPLICATIONSThe test proposed in this study, assimilable to a maximal isometric mid-thigh pull, appears to detect the acute assistance provided by the exoskeleton, expressed as the difference in performance with and without donning the device; the test can be perform...

Adaptive Multirobot Virtual Structure Control using Dual Quaternions
This paper presents a dual-quaternion-based control strategy for the coordinated formation flying of small UAV teams. A virtual structure is used to define the formation, enabling a unified and global representation of its pose and of the geometric variables that shape the format...
