The generation of high-power laser pulses using a compact hetero-integrated assembly based on a semiconductor laser with a dual-element composite 2 μm × 100 μm aperture and a compact heterothyristor switch is demonstrated. The achieved peak optical power was 33 W with a pulse duration of 3 ns at a thyristor operating voltage of 55 V. The leading edge of the laser pulse turn-on was 50 ps to a power level of 24.7 W, and the turn-on delay between the elements of the composite aperture was 160 ps.

What can we learn from the history of aging research?

History & Philosophy of Medicine 2024年第2期6卷 4-5页

作者： ilia Stambler Department of Science Technology and SocietyBar-Ilan UniversityRamat Gan 5290002Israel

There is currently a massive movement advocating for the enhancement of biomedical research on aging,sometimes referred to as“longevity advocacy”or“longevity activism”[1].The principal argument of the longevity advocacy movement is that the therapies developed by biomedical research of aging should enable us to directly intervene in the aging process and thus prevent multiple aging-related diseases,thereby extending healthy longevity.

Review: Practical Use of a Neurophysiological Detector and the Protocol for High-Performance Liquid Chromatography

引用

International Journal of Analytical Mass Spectrometry and Chromatography 2023年第1期11卷 1-10页

作者： ilia Brondz Norwegian Drug Control and Drug Discovery Institute (NDCDDI) AS Ski Norway

The main aim for discovery and development of the neurophysiological detector was detection of the production’ seats and criminal use of poisons in warfare. Phosphor-organic (PO) substances with acetylcholinesterase-blocking effects are prohibited in warfare by international law (Geneva Protocol. https://***/disarmament/wmd/bio/1925-geneva-protocol/). Monitoring PO analogs with acetylcholinesterase-blocking effects and their degradation products in water and soil can provide clues to unlawful production sites and the possible use of POs in warfare. Attempts to analyze POs by derivatization have had a low ability to detect them. A neurophysiological detector (NPD)-high-performance liquid chromatography (HPLC) system was developed for specific detection with high detection ability. The first official presentation of our NPD was at the 3rd International Symposium on Separation in BioSciences SBS 2003: A 100 Years of Chromatography, May 13-18, 2003, in Moscow, Russia. The NPD in connection to HPLC was developed 14 years before the presentation at the SBS in 2003. Initially, NPD combined with an HPLC system was developed for intelligence services and only for use in monitoring and espionage against the unlawful production of neuroparalytic agents, as explained in this article. NPD combined with an HPLC system was developed in Umeå, Sweden, in 1987-89;the protocol was further developed in Statens Plantevern Institutt, Ås, Norway, in 1990-92. NPD may have great utility during the current period of active warfare in Europe. The initial challenge was detecting unlawful production and use of PO compounds and their metabolites that can potentially block acetylcholinesterase. The sensor in NPD can detect and monitor substances such as tabun, soman, and modern PO poisons used in military applications. This article describes the history of the development of NPD and its aim as a sensitive sensor in detecting PO substances with acetylcholinesterase-blocking effec
