Broadband Directional Thermal Radiation with Asymmetric Femtosecond Laser‐Processed Surfaces

open access: yesAdvanced Optical Materials, EarlyView.
Femtosecond laser processing is used to scalably create self‐organized angled microstructures which exhibit highly directional emissivity that occurs for all polarizations. Laser parameters are tuned to alter the surface features, control the direction of emission, and enhance the directional emissivity. Electromagnetic modeling is performed to analyze

Compliant Polymeric Sheet‐Based Heat Exchangers

open access: yesAdvanced Science, EarlyView.
This work presents flexible, transparent, and deployable polymer heat exchangers that achieve a heat transfer capacity per cost up to 4x higher than the state of the art, surpassing both metal and other polymer counterparts. The tube‐on‐tube design enables efficient heat transfer without flow occlusion, while the lightweight, corrosion‐resistant, and ...

Microbiome Analyses Demonstrate Specific Communities Within Five Shark Species

open access: yesFrontiers in Microbiology, 2021
Profiles of symbiotic microbial communities (“microbiomes”) can provide insight into the natural history and ecology of their hosts. Using high throughput DNA sequencing of the 16S rRNA V4 region, microbiomes of five shark species in South Florida (nurse,

Interactive Prompt‐Guided Robotic Grasping for Arbitrary Objects Based on Promptable Segment Anything Model and Force‐Closure Analysis

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A laser pointer‐guided robotic grasping method for arbitrary objects based on promptable segment anything model and force‐closure analysis is presented. Grasp generation methods based on force‐closure analysis can calculate the optimal grasps for objects through their appearances. However, the limited visual perception ability makes robots difficult to

Stereo videography reveals fragility in a high value thresher shark population

open access: yesFrontiers in Marine Science
Population risk assessments are important tools for understanding the sustainability of shark populations and informing their conservation. In the Philippines, policy makers have made inroads to progress legislative protection for sharks in recent years,

The Relative Abundance and Occurrence of Sharks off Ocean Beaches of New South Wales, Australia

open access: yesBiology, 2022
There is still limited information about the diversity, distribution, and abundance of sharks in and around the surf zones of ocean beaches. We used long-term and large-scale drone surveying techniques to test hypotheses about the relative abundance and ...

European Shark Fisheries: A Preliminary Investigation into Fisheries, Conversion Factors, Trade Products, Markets and Management Measures [PDF]

open access: yes, 2007
Recommends new regulations to prevent shark finning -- an illegal practice in which a shark's fins are removed and its carcass dumped at sea -- and stresses the urgent need for effective shark conservation ...

Mesopelagic Fish as a Promising New Source of Omega‐3 Fatty Acids in Comparison With Australian Commercial Seafood

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Global dietary guidelines consistently recommend regular seafood consumption to support adequate omega‐3 long‐chain (≥ C20) polyunsaturated fatty acid (n‐3 LC‐PUFA) intake. Most international health authorities advise two servings of seafood per week, including at least one serve of oily fish, to achieve approximately 500 mg/day of combined ...
