An application of residue number system arithmetics to secure hash functions design [PDF]
Bulletin of Natural Sciences ResearchThis paper presents a cryptographic hash function based on the Residue Number System (RNS), designed to enhance security and computational efficiency. The function leverages the parallelism and modular properties of RNS to achieve high-speed processing ...

Collective effects in charge transfer within a hybrid organic-inorganic system
, 2009 A collective electron transfer (ET) process was discovered by studying the current noise in a field effect transistor with light-sensitive gate formed by nanocrystals linked by organic molecules to its surface.

Population mechanisms of the green Er3+:LiYF4 laser [PDF]
, 1995 In computer simulations the mechanisms that lead to room-temperature continuous-wave green upconversion lasing in Er3+:LiYF4 are investigated. The rate-equation system considers the full erbium level scheme up to 2H9/2, ground-state depletion, excited ...

Wet-snow avalanche interaction with a deflecting dam: field observations and numerical simulations in a case study [PDF]
Natural Hazards and Earth System Sciences, 2012 In avalanche-prone areas, deflecting dams are widely used to divert avalanches away from endangered objects. In recent years, their effectiveness has been questioned when several large and multiple avalanches have overrun such dams.

Experimental Investigation of Plastic Deformations Before Granular Avalanche
, 2012 We present an experimental study of the deformation inside a granular material that is progressively tilted. We investigate the deformation before the avalanche with a spatially resolved Diffusive Wave Spectroscopy setup.

Keyed Hash Function Using Hyper Chaotic System With Time-Varying Parameters Perturbation
IEEE Access, 2019 Secure hash function plays an important role in cryptography. This paper constructs a hash algorithm using the hyperchaotic Lorenz system, which serves as a sponge function to absorb input message via multiple parameters time-varying perturbation. First,

Tree Blow‐Down by Snow Avalanche Air‐Blasts: Dynamic Magnification Effects and Turbulence
Geophysical Research Letters, 2023 Snow avalanche‐induced air‐blasts are capable of breaking trees, damaging buildings and causing fatalities. Predicting their destructive properties is an essential part of snow avalanche hazard mitigation.
