Collisions and Near-Collisions for Reduced-Round Tiger [PDF]
, 2006 We describe a collision-finding attack on 16 rounds of the Tiger hash function requiring the time for about 244 compression function invocations. This extends to a collision-finding attack on 17 rounds of the Tiger hash function in time of about 249 compression function invocations.

Colisão com o 'efeito estilingue'
Revista Brasileira de Ensino de FísicaAbordamos teoricamente a colisão com o 'efeito estilingue' onde um corpo transfere momento linear e energia cinética para um segundo corpo de massa menor, fazendo com que a energia mecânica desse segundo corpo cresça de forma surpreendente. Mostramos que,

Collision scenarios and probabilistic collision damage [PDF]
Marine Structures, 2002 This paper examines the influence of collision scenario random variables on the extent of predicted damage in ship collisions. Struck and striking ship speed, collision angle, striking ship type and striking ship displacement are treated as independent random variables. Other striking ship characteristics are treated as dependent variables derived from

, 2011 We predict the polarization of cosmic microwave background (CMB) photons that results from a cosmic bubble collision. The polarization is purely E-mode, symmetric around the axis pointing towards the collision bubble, and has several salient features in ...

Advanced Functional Materials, EarlyView.Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Advanced Functional Materials, EarlyView.This work demonstrates an interphase strain engineering strategy to regulate capacitive energy storage performance in high‐entropy oxide thin films. Through introducing pyrochlore nanocolumns, the polarization response of perovskite unit cells is strengthened, yielding recoverable energy densities up to 93 J cm−3 with an efficiency of 83% under ...
