Regional Anesthesia for Urgent Reconstructive Surgery [PDF]

open access: yes, 2019
In polytrauma patients, the primary goal is to administer early resuscitation and effective analgesia with medications or techniques, which minimally affect the patient’s physiology.

Enantioconvergent Deacylative Functionalization toward α‐Quaternary Nitriles

open access: yesAngewandte Chemie, EarlyView.
An enantioconvergent quaternary‐to‐quaternary synthesis of α‐chiral nitriles has been enabled. By replacing the acyl group with a variety of allyl, propargyl, and benzyl motifs, the functional group swap can convert easily available β‐ketonitriles to assorted quaternary stereocenters en route to bioactive molecules of broad interests.

A theoretical study on a two-dimensional flap-type wavemaker [PDF]

open access: yesarXiv, 2020
A mathematical model for unidirectional wave generation explained in this study. The model consists of Laplace's equation in the semi-infinite two-dimensional water interior, dynamic and kinematic boundary conditions at the free surface, lateral boundary condition on the wavemaker, and fixed wall at the bottom.

Retrospective analysis of free temporoparietal fascial flap for defect reconstruction of the hand and the distal upper extremity [PDF]

open access: yes, 2020
Introduction: Soft tissue reconstruction of the hand and distal upper extremity is challenging to preserve the function of the hand as good as possible. Therefore, a thin flap has been shown to be useful. In this retrospective study, we aimed to show the

Multistable Composite Laminate Grids as a Design Tool for Soft Reconfigurable Multirotors

open access: yesAdvanced Intelligent Systems, EarlyView.
Flexible, lightweight, stable: the reconfigurable multirotor combines stable flight in multiple shapes with low‐energy reconfiguration. Utilizing optimized multistable composites, it achieves self‐locking in open and folded configurations, cutting width‐span by 48% and allowing for safe gap traversal.

Linear theory for single and double flap wavemakers [PDF]

open access: yesJournal of the Indonesian Mathematical Society, 12(1): 41-57, 2006, 2017
In this paper, we are concerned with deterministic wave generation in a hydrodynamic laboratory. A linear wavemaker theory is developed based on the fully dispersive water wave equations. The governing field equation is the Laplace equation for potential flow with several boundary conditions: the dynamic and kinematic boundary condition at the free ...

"A Free thenar flap – A case report" [PDF]

open access: yes, 2007
We present a case report of a free thenar flap surgery done for a volar right hand middle finger, distal and middle phalanx degloving injury. A free thenar flap is a fasciocutaneous sensate flap supplied by a constant branch of the superficial radial ...

Spring and Power in Hovering Ornithopters

open access: yesAdvanced Intelligent Systems, EarlyView.
Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Morphy: A Compliant and Morphologically Aware Flying Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents Morphy, a 25.2 cm‐wide, 260 g aerial robot with flexible, sensorized joints that enable it to withstand high‐speed collisions and squeeze through narrow spaces. Powered by an adaptive control scheme exploiting real‐time morphology feedback, Morphy demonstrates resilience in trajectory tracking, collision, and impact recovery and ...
