Electroforming-based micro-texturing: Advancements for surface engineering in EDM by Mariana Hernández-Pérez, Pedro M. Hernández-Castellano, Juan M. Vázquez-Martínez, María D. Marrero-Alemán

“…For biomimetic textures, such as those inspired by shark skin, excellent lateral fidelity was observed, while low-relief geometric textures presented greater variations due to the accumulation of photosensitive resin in the first layers of the texturing. …”

Integrated transmission expansion planning incorporating fault current limiting devices and thyristor-controlled series compensation using meta-heuristic optimization techniques by Abdulaziz Almalaq, Khalid Alqunun, Rabeh Abbassi, Ziad M. Ali, Mohamed M. Refaat, Shady H. E. Abdel Aleem

“…The ten meta-heuristic algorithms considered in this study include Sinh Cosh Optimizer, Walrus Optimizer, Snow Geese Algorithm, Triangulation Topology Aggregation Optimizer, Electric Eel Foraging Optimization, Kepler Optimization Algorithm (KOA), Dung Beetle Optimizer, Sea-Horse Optimizer, Special Relativity Search, and White Shark Optimizer (WSO). Three TEP models incorporating fault current limiters and thyristor-controlled series compensation devices are utilized to evaluate the performance of the meta-heuristic algorithms, each representing a different scale and complexity level. …”

Effects of Urea Removal on the Stable Isotopes δ13C and δ15N in Rays from the Coastal Waters of Peninsular Malaysia by Maizah Mohd Abdullah, Wei Yien Lua, Roslanzairi Mostapha, Zalina Bashir, Mohd Naimullah, Sukree Hajisamae, Fazrul Hisam

“…Highlight Research • This is the first stable isotopes study of rays from Malaysian waters • Urea extraction significantly enriched the δ15N values ("°) • Urea removal is obliged for stable isotope studies on rays • Such methodological information is critical for marine research in the region   Abstract This is the first reported record of stable isotope values for elasmobranch rays within Malaysian waters, and serves as an important baseline methodological information for future studies investigating stable isotope values in both shark and ray species in the region. This study examined the effects of urea removal on the stable isotopes values of δ13C and δ15N in muscle tissues sampled from several elasmobranch rays species, namely Pastinachus atrus, Rhinoptera javanica, Himantura gerrardi, Himantura uarnak and Aetobatus ocellatus. …”

An Introduction to Harvest Tags for Marine Recreational Fisheries by Edward Camp, Zachary Siders, Andrew Ropicki, Frank Asche

“…This is especially a problem for Florida reef fish species that live at depths and habitats where barotrauma increases mortality and depredation by larger fish, sharks, or marine mammals increases it further. Harvest (or trip) tags could reduce overharvest, lower discard mortality, and allow anglers more freedom to choose when to fish. …”

Complementary Non‐invasive Fish Monitoring Distinguishes Depth‐Dependent Fish Communities by Ewan Burns, Vijini Mallawaarachchi, Thomas M. Clarke, Belinda Martin, Joseph D. DiBattista, Jamie Hicks, Danny Brock, Elizabeth A. Dinsdale, Charlie Huveneers, Michael P. Doane

“…BRUVS predominantly identified benthic and demersal fish, whereas eDNA predominately identified pelagic species, including species of conservation (e.g., white sharks) and commercial significance (e.g., southern bluefin tuna). …”
