An entropy-based method to measure phase-locking between LFP and spikes
AIP Advances, 2023 Phase-locking between local field potential and spikes has been widely investigated through neurophysiological analysis. Two indices most frequently adopted traditionally include the mean resultant length and p of the Rayleigh test.

High-efficiency phase-locking experiment of modular Ka-band coaxial magnetrons
AIP Advances, 2023 The first full demonstration of a high-efficiency phase-locking mechanism was accomplished in the millimeter-wave (mm wave) bands. Two modular Ka-band coaxial magnetrons were fabricated and phase-locked.

A small footprint couch‐top support device for image‐guided radiotherapy of heavy patients
Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Purpose Patients with body weights close to or above 400 lbs present unique challenges in radiation therapy since the weight limit of most treatment couches decreases as the couch‐top extends toward the treatment gantry. The purpose of this work was to develop a small footprint couch‐top support platform to safely perform image‐guided ...

Well‐being on supportive techniques in amyotrophic lateral sclerosis: from neurologists' perspective
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1874-1883, December 2022., 2022 Abstract Objective To investigate intercultural neurologists' perception of well‐being in patients with amyotrophic lateral sclerosis (ALS) using gastrostomy (PEG), non‐invasive, and/or invasive ventilation (NIV/IV) and to analyse the determinants and impact on the management of the above medical interventions (MIs).

Proceedings of the 28th ACM SIGPLAN Annual Symposium on Principles and Practice of Parallel Programming, 2023 Invented more than 40 years ago, the two-phase locking concurrency control (2PL) is capable of providing opaque transactions over multiple records. However, classic 2PL can suffer from live-lock and its scalability is low when applied to workloads with a high number of non-disjoint read accesses.

A Two-Frequency-Two-Coupling model of coupled oscillators [PDF]
Chaos 31, 083124 (2021), 2021 We considered the phase coherence dynamics in a Two-Frequency and Two-Coupling (TFTC) model of coupled oscillators, where coupling strength and natural oscillator frequencies for individual oscillators may assume one of two values (positive/negative).

Interactions Between Two Phase-Locked Loop Synchronized Grid Converters [PDF]
IEEE Transactions on Industry Applications, 2021 Grid converters synchronized by phase-locked loops (PLLs) could suffer from stability problems, especially being connected to a weak grid or high penetration of converters. The existing literature assesses the stability of the paralleled PLL-synchronized converters at the same point of common coupling (PCC) using identical control and system parameters.

ReLock: a resilient two-phase locking RESTful transaction model
Service Oriented Computing and Applications, 2021 Service composition and supporting transactions across composed services are among the major challenges characterizing service-oriented computing. REpresentational State Transfer (REST) is one of the approaches used for implementing Web services that is gaining momentum thanks to its features making it suitable for cloud computing and microservices ...
