Functional activity of peptide ion channels in tethered bilayer lipid membranes: Review

Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract Ion transport across biomembranes plays a major role in living cells. This fundamental function is normally carried out by molecules with both a hydrophobic and a hydrophilic side (amphiphilic molecules), which aggregate within the membrane forming a hydrophilic pore (the ion channel) permitting the selective translocation of permeant ions ...

NIR‐Sensitized Activation of Lophyl Radicals by Heptamethine Cyanines Enables Dry Film Photoresists

Angewandte Chemie International Edition, Accepted Article.
The near‐infrared (NIR) sensitized generation of lophyl radicals (L∙) by heptamethine cyanine led to initiation of radical photopolymerization of multi‐functional acrylates when different hexaarylbisimidazoles (HABIs) and N‐phenylglycine (NPG) operated coinitiator. The latter functioned as donor.

ControlLoc: Physical-World Hijacking Attack on Visual Perception in Autonomous Driving [PDF]

arXiv
Recent research in adversarial machine learning has focused on visual perception in Autonomous Driving (AD) and has shown that printed adversarial patches can attack object detectors. However, it is important to note that AD visual perception encompasses more than just object detection; it also includes Multiple Object Tracking (MOT).

Less is More: A Stealthy and Efficient Adversarial Attack Method for DRL-based Autonomous Driving Policies [PDF]

arXiv
Despite significant advancements in deep reinforcement learning (DRL)-based autonomous driving policies, these policies still exhibit vulnerability to adversarial attacks. This vulnerability poses a formidable challenge to the practical deployment of these policies in autonomous driving.

Automating Collision Attacks on RIPEMD-160 [PDF]

As an ISO/IEC standard, the hash function RIPEMD-160 has been used to generate the Bitcoin address with SHA-256. However, due to the complex double-branch structure of RIPEMD-160, the best collision attack only reaches 36 out of 80 steps of RIPEMD-160 ...

Atypical Postural Control Variability and Coordination Persist Into Middle and Older Adulthood in Autism Spectrum Disorder

Autism Research, EarlyView.
ABSTRACT Postural control deviations remain largely unexplored in middle aged and older autistic adults. With the increased prevalence of neurodegenerative conditions and heightened fall risk, precise quantification of postural variability and coordination may provide valuable insights into aging associated neuromotor deviations in autistic adults ...
