PairTilt: Design and Control of an Active Tilt‐Rotor Quadcopter for Improved Efficiency and Agility

Advanced Intelligent Systems, EarlyView.
PairTilt is an actuated tilt‐rotor unmanned aerial vehicle capable of active shape reconfiguration, balancing simplicity, efficiency, and agility. Its H‐shaped frame incorporates pairwise tiltable rotors, which reduce gyroscopic torque and decouple key dynamics, enhancing maneuverability and reducing drag.

Mapping the Catalytic Cycle of Ru‐Catalyzed Ammonia Oxidation

Angewandte Chemie, EarlyView.
The graph illustrates the complete electrochemical ammonia oxidation catalytic cycle by a ruthenium complex, capturing most intermediates. The pathways bifurcate at [RuIII(NH2)]2+ and [RuII(N2H4)]2+, highlighting competitive steps including dimerization, nucleophilic attack, and disproportionation.

GACNet: Interactive Prediction of Surrounding Vehicles Behavior under High Collision Risk

Advanced Intelligent Systems, EarlyView.
This study designs a dual‐stage prediction framework and introduces a conflict analysis module. This module refines the initially predicted future trajectories and performs collision detection and behavior analysis on the refined trajectories, thereby learning the true interactive behaviors of multiple agents in high‐collision‐risk scenarios.

Defense Strategies for Autonomous Multi-agent Systems: Ensuring Safety and Resilience Under Exponentially Unbounded FDI Attacks [PDF]

arXiv
False data injection (FDI) attacks pose a significant threat to autonomous multi-agent systems (MASs). While resilient control strategies address FDI attacks, they typically have strict assumptions on the attack signals and overlook safety constraints, such as collision avoidance.

Identifying the optimal dose of cannabidiol by intrabuccal administration in Kramnik (C3HeB/FeJ) mice

Animal Models and Experimental Medicine, EarlyView.
Cannabidiol (CBD) has numerous therapeutic properties, and is used to treat neurological conditions, such as neuroinflammation. However, the optimal dose of CBD to penetrate the brain requires further investigation. The primary aim of this study was to use a mouse model and the intrabuccal route for CBD administration to determine the optimal dose at ...

Microwave‐assisted poly(D,L‐lactide) synthesis in toluene and tetrahydrofuran

Journal of Advanced Manufacturing and Processing, EarlyView.
Abstract Poly(d,l‐lactide) is a biocompatible and biodegradable polymer with applications in the biomedical field (drug delivery, implants) and packaging. Conventional synthesis with stannous octoate is slow (>4 h) and can climb to over 30 h. In order to reduce reaction times, we developed a microwave reactor process to ring‐open polymerize d,l‐lactide

Longitudinal Proteomic Profiling of Cognition across an Aerobic Exercise Intervention

Annals of Neurology, EarlyView.
The physiological basis of cognitive decline remains largely uncharacterized. We identified a protein panel signature, in living humans, that correlates to improvement in neurocognition over a period of 5 years. Our signature is composed of complement proteins, coagulation cascade, and extracellular matrix regulators.

A Formula That Generates Hash Collisions

, 2018
We present an explicit formula that produces hash collisions for the Merkle-Damg{\aa}rd construction. The formula works for arbitrary choice of message block and irrespective of the standardized constants used in hash functions, although some padding ...

Opening the Blackbox: Collision Attacks on Round-Reduced Tip5, Tip4, Tip4’ and Monolith

IACR Transactions on Symmetric Cryptology
A new design strategy for ZK-friendly hash functions has emerged since the proposal of Reinforced Concrete at CCS 2022, which is based on the hybrid use of two types of nonlinear transforms: the composition of some small-scale lookup tables (e.g., 7-bit

Noble Gas Provides a Solution to the Synthesis‐On‐Inert‐Surfaces Challenge for Extended Covalent Nanostructures

Angewandte Chemie International Edition, EarlyView.
Noblesse oblige! The noble gas argon can be used to form carbon‐sulfur‐carbon thioether‐based nanostructures on inert surfaces such as graphite. In contrast to on‐surface synthesis on metal surfaces, this may allow the exploration of novel field‐effect devices.
