Dynamic Obstacle Avoidance of Metamorphic Microrobots Using Concentric Sector Navigator

Advanced Intelligent Systems, EarlyView.
Metamorphic magnetic microrobots are navigated using a concentric sector navigator for dynamic obstacle avoidance in both microroller and swarm states. After microroller transport, citrate‐triggered dissolution releases nanoparticles that reassemble into a controllable swarm.

Development of an Inchworm‐Like Dual‐Balloon‐Assisted Colonoscopic Robot Based on a Two‐Segment Extensible Continuum Section

Advanced Intelligent Systems, EarlyView.
This work presents an inchworm‐like dual‐balloon‐assisted colonoscopic robot (IDCR) based on a rod‐driven two‐segment continuum section. The IDCR enables the active straightening of the sigmoid colon through an inchworm‐like locomotion strategy, thereby avoiding loop formation.

Freedom dreaming of migrant justice: Critical reflections on counterspaces and institutional violence in the university

American Journal of Community Psychology, EarlyView.
Abstract US universities are built on stolen land and sustained through hierarchies of power that produce what migrant justice scholars name as b/order regimes. As institutions that claim to be sites of learning and inclusion, universities are fraught with contradictions as simultaneously sites of dispossession, exclusion, and control.

Anti-Collision Warning System at Ghat Section

This work presents the design and development of an IoT-based Anti-Collision Warning System (ACWS) aimed at improving road safety in accident-prone ghat sections. The system integrates LiDAR, Ultrasonic, and Infrared sensors with Arduino and IoT connectivity to detect vehicles in blind spots and issue real-time alerts through LEDs, buzzers, and ...

Influence of Direct Saponification Conditions on Sterol Yield and Composition of the Unsaponifiable Fraction of the Microalga Isochrysis galbana and the Seaweed Ascophyllum nodosum

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,

Valorization of bark extracts from Cerrado and Amazon species: phenolic characterization, antioxidant capacity, and photoprotective potential for circular bioeconomy applications

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Tree bark remains an underexploited source of high‐value‐added phenolic compounds with potential circular bioeconomy applications. This work characterized bark extracts from two species of distinct Brazilian biomes, Stryphnodendron adstringens (Cerrado) and Myrcia eximia (Amazon), obtained with three solvents (ethanol, methanol and acetone ...

Glucocorticoid exposure and initiation of SSRIs among patients with rheumatoid arthritis: A nested case–control study in UK primary care

British Journal of Clinical Pharmacology, EarlyView.
Aim The immune system might affect the development of anxiety disorders, though mechanisms remain unclear. This nested case–control study investigates whether use of glucocorticoids, potent immunosuppressants, is associated with SSRI initiation (a proxy for pharmacologically treated mental disorders, predominantly depression and/or anxiety).
