Impact of proctoring on success rates for percutaneous revascularisation of coronary chronic total occlusions. [PDF]

, 2015
OBJECTIVE: To assess the impact of proctoring for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) in six UK centres. METHODS: We retrospectively analysed 587 CTO procedures from six UK centres and compared success rates of ...

Synchrotron‐Based Trauma Assessment of Robotic Electrode Insertions in Cochlear Implantation

The Laryngoscope, EarlyView.
Minimizing intraoperative trauma during cochlear implant electrode insertion is crucial for preserving residual hearing, and efforts have been made to introduce robotic systems for electrode insertion. On temporal bone specimens, the OTODRIVE system demonstrated its ability to enable consistent and controlled electrode placement while minimizing trauma

Tailorable Nanoparticles for Magnetic Water Cleaning of Polychlorinated Biphenyls

Small Methods, EarlyView.
Polychlorinated biphenyls (PCBs) are human‐made persistent organic pollutants omnipresent in the earth's hydrosphere, which are reported hazardous to humans as well as wildlife. This study presents surface functionalized magnetic nanoparticles that can remove such contaminants from water with an adjustable preference for most concerning compounds ...

Optimal performance design of bat algorithm: An adaptive multi‐stage structure

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract The bat algorithm (BA) is a metaheuristic algorithm for global optimisation that simulates the echolocation behaviour of bats with varying pulse rates of emission and loudness, which can be used to find the globally optimal solutions for various optimisation problems. Knowing the recent criticises of the originality of equations, the principle

At the Early Stage of the Ideation Process: Measurement, Antecedents and Outcomes of Individual Exploratory Behaviours

Creativity and Innovation Management, EarlyView.
ABSTRACT The exploration of opportunities is a major precondition for idea generation. Despite its relevance, theoretical approaches to innovation have paid scant attention to its conceptualization, measurement, antecedents and outcomes. To fill this void, this paper adopts a behavioural approach to delve into the micro‐foundations of this early stage ...

A Prototype PCI-based Data Acquisition System for Cosmic Ray Detection Below 10^18 eV [PDF]

arXiv, 2006
A prototype flash analog-to-digital readout system for cosmic ray detection at energies below 10^18 eV has been designed and tested at Columbia University Nevis Laboratories. The electronics consist of an FADC module that digitizes 16 photomultipliers at 40 MHz with 14-bit dynamic range.

Imaging‐Aided VT Ablation. Long‐Term Results From a Pilot Study

Journal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Ventricular tachycardia (VT) ablation has become a cornerstone of patient care, especially for post‐MI VT. Several strategies have proven effective for achieving rhythm control in this population, but the workflow is highly variable and depends on the physician's experience. Aim This study describes the initial systematic experience
