Two‐Dimensional Isotropic Spatial Differentiation Through Complete Polarization Control

Advanced Optical Materials, EarlyView.
This work enables two‐dimensional isotropic spatial differentiation at planar interfaces over a wide range of incident angles by extending the output polarization from linear to elliptical. The choice of incident angle can be used to balance broader spectral response at low angles and higher edge‐detection efficiency at larger angles.

Selective Feeding and Microalgal Consumption Rates by Crown-Of-Thorns Seastar (Acanthaster cf. solaris) Larvae

Diversity, 2017
Outbreaks of the crown-of-thorns seastar (CoTS) represent a major cause of coral loss on the Great Barrier Reef. Outbreaks can be explained by enhanced larval survival supported by higher phytoplankton availability after flood events, yet little is known

Physiological and transcriptomic responses to starvation in the corallivorous crown-of-thorn starfish

Frontiers in Marine Science, 2022
The outbreak of coral-eating Acanthaster spp., commonly known as the Crown-of-Thorn Starfish (CoTS), contributes to a significant proportion of coral loss in the tropical Indo-Pacific region.

From Explicit CoT to Implicit CoT: Learning to Internalize CoT Step by Step

CoRR
When leveraging language models for reasoning tasks, generating explicit chain-of-thought (CoT) steps often proves essential for achieving high accuracy in final outputs. In this paper, we investigate if models can be taught to internalize these CoT steps.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Vacuums of the sea: Ecological function of large coral reef benthic scavengers in suppressing crown-of-thorns starfish (COTS) outbreaks

Ideas in Ecology and Evolution
Despite their drastic impacts on coral reefs, outbreaks of the coral-feeding seastar crown-of-thorns starfish (COTS), Acanthaster, have remained a scientific enigma.

Multi-species consumer jams and the fall of guarded corals to crown-of-thorns seastar outbreaks [version 2; referees: 2 approved]

F1000Research, 2018
Outbreaks of predatory crown-of-thorns seastars (COTS) can devastate coral reef ecosystems, yet some corals possess mutualistic guardian crabs that defend against COTS attacks.

A Review of the Giant Triton (Charonia tritonis), from Exploitation to Coral Reef Protector?

Diversity, 2022
Charonia tritonis (Charoniidae), one of the largest marine gastropods and an echinoderm specialist, preys on Crown-of-Thorns starfish (CoTS), a recurring pest that continues to be a leading cause of coral mortality on Indo-Pacific reefs.

WorMa: An Undulatory Robot With Center of Mass Regulation via Internal Fluid Redistribution for Amphibious Locomotion

Advanced Robotics Research, EarlyView.
WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

Defined Dinuclear Nickel Sites on Mesoporous Silica Translate Molecular Surface Mimics to Heterogeneous Catalysis

Angewandte Chemie, EarlyView.
The cooperative reactivity characteristic of molecular dinuclear nickel complexes is transferred to mesoporous silica through a systematic immobilization strategy. The resulting material preserves the key features of the bimetallic motif within a robust heterogeneous framework, demonstrating how molecular design principles can be translated into well ...
