Evolutionary history of an island endemic, the Azorean common quail

Molecular Ecology, Volume 33, Issue 24, December 2024.
Abstract Oceanic islands are characterized by conditions that favour diversification into endemic lineages that can be very different from their mainland counterparts. This can be the result of fast phenotypic divergence due to drift or the result of slower adaptation to local conditions. This uniqueness can obscure their evolutionary history.

Combined genetic algorithm and response surface methodology‐based bi‐optimization of a vertical‐axis wind turbine numerically simulated using CFD

Energy Science &Engineering, Volume 12, Issue 10, Page 4532-4548, October 2024.
The optimum values of moment and lift force for a vertical axis wind turbine were determined by a multi‐objective optimization methodology including response surface methodology (RSM), computational fluid dynamic (CFD), Non‐Dominated Sorting Genetic Algorithm (NSGA‐II), and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS).

A Naturally Inspired Extrusion‐Based Microfluidic Approach for Manufacturing Tailorable Magnetic Soft Continuum Microrobotic Devices

Advanced Materials, Volume 36, Issue 31, August 1, 2024.
Here, microfluidics is leveraged to precisely control reaction‐diffusion (RD) processes for generating multifunctional and compartmentalized alginate‐based microfibers. This nature‐inspired RD process allows for producing sophisticated fibers acting as magnetic soft continuum robots.

A Review of Somatic Design for Soft Robotic Grippers: From Parts Integration to Functional Synergy

Advanced Intelligent Systems, Volume 6, Issue 8, August 2024.
Somatic design is crucial for soft grippers to emulate the embodied intelligence of their biological counterparts, due to the blurry boundaries among material, structure and function. There are five critical parts in somatic design, including morphology, material, fabrication, actuation, and variable stiffness. The strong nonlinear coupling among these
