Invariant Elimination of Definite Iterations over Arrays in C Programs Verification

open access: yesМоделирование и анализ информационных систем, 2017
This work represents the further development of the method for definite iteration verification [7]. It extends the mixed axiomatic semantics method [1] suggested for C-light program verification. This extension includes a verification method for definite

Aerosol Susceptibility of Influenza Virus to UV-C Light [PDF]

open access: yesApplied and Environmental Microbiology, 2012
ABSTRACTThe person-to-person transmission of influenza virus, especially in the event of a pandemic caused by a highly virulent strain of influenza, such as H5N1 avian influenza, is of great concern due to widespread mortality and morbidity. The consequences of seasonal influenza are also substantial.

RIFTA: A Robust Iterative Fourier Transform-based dwell time Algorithm for ultra-precision ion beam figuring of synchrotron mirrors

open access: yesScientific Reports, 2020
With the rapid evolution of synchrotron X-ray sources, the demand for high-precision X-ray mirrors has greatly increased. Single nanometer profile error is required to keep imaging capability at the diffraction limit. Ion Beam Figuring (IBF), as a highly

Long-lasting XUV activation of helium nanodroplets for avalanche ionization

open access: yesNew Journal of Physics, 2023
We study the dynamics of avalanche ionization of pure helium nanodroplets activated by a weak extreme-ultraviolet (XUV) pulse and driven by an intense near-infrared (NIR) pulse.

Statistical Tool Size Study for Computer-Controlled Optical Surfacing

open access: yesPhotonics, 2023
Over the past few decades, computer-controlled optical surfacing (CCOS) systems have become more deterministic. A target surface profile can be predictably achieved with a combination of tools of different sizes. However, deciding the optimal set of tool

Schiff Bases and Stereocontrolled Formation of Fused 1,3-Oxazolidines from 1-Amino-2-Indanol: A Systematic Study on Structure and Mechanism

open access: yesMolecules, 2023
This paper thoroughly explores the formation of Schiff bases derived from salicylaldehydes and a conformationally restricted amino alcohol (1-amino-2-indanol), as well as the generation of 1,3-oxazolidines, a key heterocyclic core present in numerous ...

Active and durable R2MnRuO7 pyrochlores with low Ru content for acidic oxygen evolution

open access: yesNature Communications, 2023
The production of green hydrogen in water electrolyzers is limited by the oxygen evolution reaction (OER). State-of-the-art electrocatalysts are based on Ir. Ru electrocatalysts are a suitable alternative provided their performance is improved.

Electron correlation dynamics in atomic Kr excited by XUV pulses and controlled by NIR laser pulses of variable intensity

open access: yesNew Journal of Physics, 2023
We have investigated the possibility to track and control correlation dynamics of valence electrons in krypton (Kr) initiated by the absorption of one extreme ultraviolet (XUV) photon.
