Laser Ablation Sampling With Low-Power Plasma: A LA-MIP-MS Instrument for Spaceflight. [PDF]
Rapid Commun Mass SpectromABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

Transverse Bragg-resonant enhancement of modulation and switching [PDF]
, 2004 We demonstrate theoretically that the electrooptic phase retardation, hence, modulation, can be enhanced very substantially in transverse Bragg resonance (TBR) waveguides.

Advanced Science, EarlyView.ZBTB21 is a transcription factor that epigenetically suppresses pyroptosis and MHC‐I antigen presentation, enabling tumor immune evasion. Genetic ablation of ZBTB21 activates pyroptotic cell death and enhances antigen presentation, recruiting CD8+ T cells to overcome immune checkpoint blockade resistance.

Mathematical model of the LLC resonant converter
Proceedings of Tomsk State University of Control Systems and Radioelectronics, 2020 The numerical-analytical model of the voltage regulator based on full-bridge LLC resonant converter is proposed in this paper. In the text of the article LLC converters operation algorithm on each working interval is investigated. The proposed mathematical model describes key elements behavior on duty cycle and allows the study of nonlinear dynamic ...
