Packet Error Probability and Effective Throughput for Ultra-Reliable and Low-Latency UAV Communications
(IEEE, 2021-01)
In this paper, we study the average packet error probability (APEP) and effective throughput (ET) of the control link in unmanned-aerial-vehicle (UAV) communications, where the ground central station (GCS) sends control ...
An Inhomogeneous Structured Eversion Actuator
(Springer, 2020-12-01)
Soft actuators are free from any rigid, bulky, and hard components. This is greatly beneficial towards achieving compliant actuation and safe interactions in robots. Inspired by the eversion principle, we develop a novel ...
Evaluation of a novel non-destructive catch and release technology for harvesting autologous adult stem cells.
(Public Library of Science, 2013-01-22)
BACKGROUND: Cell based therapies are required now to meet the critical care needs of paediatrics and healthy ageing in an increasingly long-lived human population. Repair of compromised tissue by supporting autologous ...
External versus internal fixation for bicondylar tibial plateau fractures: systematic review and meta-analysis.
(Springer Nature, 2015-08-26)
BACKGROUND: It is uncertain whether external fixation or open reduction internal fixation (ORIF) is optimal for patients with bicondylar tibial plateau fractures. MATERIALS AND METHODS: A systematic review using Ovid ...
Designing clinical trials in trauma surgery: overcoming research barriers.
(British Editorial Society of Bone and Joint Surgery, 2014-04-24)
The surgical community is plagued with a reputation for both failing to engage and to deliver on clinical research. This is in part due to the absence of a strong research culture, however it is also due to a multitude of ...
A feeder-free, human plasma-derived hydrogel for maintenance of a human embryonic stem cell phenotype in vitro.
(BioMed Central Ltd., 2012-08-08)
BACKGROUND: Human embryonic stem cells (hESCs) represent a tremendous resource for cell therapies and the study of human development; however to maintain their undifferentiated state in vitro they routinely require the use ...
Design and Analysis of a Novel Reconfigurable Parallel Manipulator with Kirigami-inspired Bennett Plano-Spherical Linkages and Angular Pouch Motors
(The American Society of Mechanical Engineers, 2021-05)
Drawing inspiration from kirigami, this article first presents the crease pattern of a kirigami model which is kinematically equivalent to a Bennett plano-spherical linkage. In terms of the screw theory, distinct closed-loop ...
SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study.
(2021-03-24)
BACKGROUND: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. METHODS: The primary outcome was the number ...
