Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

Advanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal [PDF]

, 2016
Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view ...

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans

Advanced Science, EarlyView.
Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

BioCNTs Mediated Delivery of Systemically Mobile Small RNAs via Leaf Spray to Control Both Tomato DNA and RNA Viruses

Advanced Science, EarlyView.
A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.

Lighting constraints on lunar surface operations [PDF]

An investigation into the levels of ambient lighting on the lunar surface indicates that for most nearside locations, illumination will be adequate throughout most of the lunar night to conduct EVAs with only minor artificial illumination.

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

Advanced Science, EarlyView.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.

Remimazolam Ameliorates Autistic‐Like Behaviors via Suppression of Ferroptosis in VTA Dopaminergic Neurons in a Mouse Model of ASD

Advanced Science, EarlyView.
The ultra‐short‐acting sedative remimazolam has a sustained therapeutic effect on the core symptoms of VPA‐exposed mice. Remimazolam, a GABA agonist, exerts its therapeutic effects by protecting dopamine neurons in the VTA of VPA‐exposed mice. Meanwhile, ferroptosis is the critical mechanism by which remimazolam protects VTA dopaminergic neurons and ...

Analyzing the Sources and Variations of Nighttime Lights in Hong Kong from VIIRS Monthly Data

Remote Sensing
The long-term monitoring of nighttime lights is essential for understanding sources of light pollution. Nighttime lights observed in space are affected by atmospheric conditions as they transmit from the Earth surface through clouds and aerosols to the ...

Gαi1/3 Is a Novel Regulatory Target for RANKL Signal Transduction and Osteoporosis

Advanced Science, EarlyView.
ABSTRACT Osteoporosis, characterized by progressive bone loss and increased fracture risk, is a growing concern as the population ages. Current treatments, though advanced, remain limited, underscoring the necessity for novel therapeutic targets. Recent studies have shown that the immune system plays a key role in osteoporosis, with osteoclasts driving
