An Integrated Subharmonic Coupled-Oscillator Scheme for a 60-GHz Phased-Array Transmitter [PDF]
, 2006 This paper describes the design of an integrated coupled-oscillator array in SiGe for millimeter-wave applications. The design focuses on a scalable radio architecture where multiple dies are tiled to form larger arrays. A 2 × 2 oscillator array for a 60-

Stable coherent mode-locking based on $$\pi$$ π pulse formation in single-section lasers
Scientific Reports, 2021 Here we consider coherent mode-locking (CML) regimes in single-section cavity lasers, taking place for pulse durations less than atomic population and phase relaxation times, which arise due to coherent Rabi oscillations of the atomic inversion ...

Multi-Mode Lasers for Self-Forced Opto-Electronic Oscillators in Compact Frequency Synthesizers
IEEE Journal of Microwaves, 2021 Advanced telecommunication, imaging, and remote sensing systems require reliable ultra-high stability local oscillators. Particularly, coherent detection of digital data signals relies on a low aperture jitter of local oscillators in addition to high ...

, 2014 When a driven oscillator loses phase-locking to a master oscillator via a Hopf bifurcation, it enters a bounded-phase regime in which its average frequency is still equal to the master frequency, but its phase displays temporal oscillations.

Strong consistency is not hard to get
Proceedings of the VLDB Endowment, 2019 Concurrency control is a cornerstone of distributed database engines and storage systems. In pursuit of scalability, a common assumption is that Two-Phase Locking (2PL) and Two-Phase Commit (2PC) are not viable solutions due to their communication overhead.

Abnormal Synchronization Between Cortical Delta Power and Ripples in Hippocampal Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Discriminating between epileptogenic and physiological ripples in the hippocampus is important for identifying epileptogenic (EP) zones; however, distinguishing these ripples on the basis of their waveforms is difficult. We hypothesized that the nocturnal synchronization of hippocampal ripples and cortical delta power could be used ...

Phase synchronization from noisy univariate signals
, 2004 We present methods for detecting phase synchronization of two unidirectionally coupled, self-sustained noisy oscillators from a signal of the driven oscillator alone. One method detects soft, another hard phase locking. Both are applied to the problem of

Cortical Excitability Before and After Long‐Term Perampanel Treatment for Epilepsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Antiseizure medications (ASMs), which may influence cortical excitability, are the mainstay of epilepsy treatment. Transcranial magnetic stimulation (TMS) helps evaluate cortical excitability. We assessed changes in TMS responses using serial TMS measurements in people treated with an adjunctive noncompetitive AMPA‐receptor ...

Concrat: An Automatic C-to-Rust Lock API Translator for Concurrent Programs [PDF]
arXiv, 2023 Concurrent programs suffer from data races. To prevent data races, programmers use locks. However, programs can eliminate data races only when they acquire and release correct locks at correct timing. The lock API of C, in which people have developed a large portion of legacy system programs, does not validate the correct use of locks.
