High-repetition-rate x-ray preionization source [PDF]

, 1990
A high repetition rate X-ray source for preionization of high-pressure self sustained laser discharges has been studied. Use has been made of a corona plasma cathode and a water cooled reflective target.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Performance of laser ablation propulsion with a high-repetition rate and high-power laser

AIP Advances, 2022
We investigated the propulsive performance of laser ablation propulsion using a high-power and highly repetitive pulsed laser. We demonstrated 100 shots of burst laser irradiation with an aluminum target using repetition frequencies of 0.017 Hz and 1 kHz.

High-Repetition-Rate Burst Pulser [PDF]

Review of Scientific Instruments, 1967
This paper describes a simple and reliable thyratron circuit capable of generating high energy pulses at repetition rates of 5000/sec or higher. Design considerations and factors limiting the maximum repetition rate are discussed.

Repetition Rate Multiplication Pulsed Laser Source Based on a Microring Resonator

, 2017
We demonstrate a stable high-Q microring resonator (MRR)-based pulsed laser source with adjustable repetition rate from 49 to 735 GHz, corresponds to repetition rate multiplication of up to 15X the free spectral range (FSR) of the MRR.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

All-Solid-State Post-Compression of Low-Energy Pulses at High Repetition Rate

Photonics
We demonstrate a proof of principle of a simple all-solid-state post-compression setup for low-energy, high-repetition-rate laser pulses, where spectral broadening was performed using a combination of highly nonlinear bulk materials in a simple single ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Full characterization of low-power picosecond pulses from a gain-switched diode laser using electro-optic modulation-based linear FROG

, 2007
We use a linear frequency-resolved optical gating technique based on electrooptic modulation to fully characterize for the first time the highly chirped pulses from a 1.06 µm Fabry-Perot laser diode and design a chirped fiber Bragg grating to provide ...
