Video data recovery from slack space of pre‐allocated video files
Journal of Forensic Sciences, EarlyView.Abstract The recovery of video evidence from dashboard cameras is often compromised by damage, file system errors, or circular recording mechanisms that overwrite older data. Traditional digital forensic techniques primarily focus on file carving and frame recovery from the unallocated area of storage media. However, this approach is often insufficient

TT4D: Tensor‐Train‐based 4D Time‐Dependent Volume Rendering
Computer Graphics Forum, EarlyView.Abstract Visualizing large‐scale, time‐varying volumetric data using direct volume rendering remains a significant challenge in scientific visualization, particularly as data sizes and resolutions continue to increase. One promising direction for addressing this challenge is the use of tensor decompositions, which have proven to be a useful tool for ...

Timing pattern of Common Cuckoo parasitism and its relation to host nest attendance
Ibis, EarlyView.Classical works show the adaptive importance of precise timing of egg‐laying in brood parasitic Common Cuckoos Cuculus canorus to ensure sufficient incubation time and successful hatching. Laying in the late afternoon has been suggested to increase the chance of secretive parasitism and therefore escape the aggressive mobbing by hosts, yet this ...
