Downconversion Master Slave OCT With a Bidirectional Sweeping Laser

Journal of Biophotonics, EarlyView.
ABSTRACT This paper explores the challenges of signal processing when using optical coherence tomography (OCT) imaging instruments driven by asymmetric MHz bidirectional sweeping lasers. A downconversion master–slave (DMS) method is proposed as a viable alternative to the traditional OCT protocol.

Improved and Automated Detection of Papillary Muscle Infarction Using Joint Bright‐ and Black‐Blood Late Gadolinium Enhancement MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Papillary muscle infarction (PMI) has been linked to significantly increased mortality and is associated with ventricular arrhythmias and mitral regurgitation. Reference bright‐blood late gadolinium enhancement (LGE) imaging provides poor scar‐to‐blood contrast, making PMI visualization challenging. Black‐blood LGE imaging overcomes

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

High‐resolution in situ characterization of laser powder bed fusion via transmission X‐ray microscopy at X‐ray free‐electron lasers

Journal of Synchrotron Radiation, EarlyView.
The first implementation of an operando transmission X‐ray microscopy to study laser melting at X‐ray free‐electron lasers is described. The instrument uses a novel pump–probe scheme to image down to 940 nm spatial resolution with integration times <100 fs and up to 0.48 GHz frame rates to study the rapid dynamics and small‐scale features in laser ...

Survivorship following myocardial infarction in a contemporary Australian cohort: defining cardiac versus non‐cardiac mortality

Internal Medicine Journal, EarlyView.
Abstract Background and Aims Progress in the management of myocardial infarction (MI) has led to reductions in cardiac mortality. The aim of this study was to describe the temporal trends in the relative proportions of cardiac death (CD) and non‐cardiac death (NCD) in an Australian cohort with MI following in‐hospital stay, then at 6 and 12 months as ...

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.
