Coexistence, crossover and extirpation in coalescent communities and ecotones

open access: yesOikos, EarlyView.
When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

Topology and opening size optimization design of solid floors in an outer tank of the pressure hull

open access: yesZhongguo Jianchuan Yanjiu, 2019
[Objectives] In order to simplify the construction process and to reduce the weight of the structure,topology optimization and opening size optimization of solid floors in an outer tank of the pressure hull are conducted.[Methods] In the study,Hyperworks/Optistruct is adopted to analyze the strength characteristic of the whole structure.

Past, present and future of local crop evolution

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Local Search and the Evolution of World Models

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...

Almond Shell‐Derived Cellulosic Microfibres: Extraction, Characterisation and Applications in Sustainable Paper‐Based Packaging

open access: yesPackaging Technology and Science, EarlyView.
Cellulosic microfibres were extracted from almond shells using organosolv, soda and kraft processes, and comprehensive physicochemical, surface, thermal and morphological characterisation demonstrated their strong potential as sustainable fillers for paper‐based packaging application. ABSTRACT This study develops pathways for the valorisation of almond

Unmanned Aerial Systems for Corrosion Detection: Multi‐Sensor Technologies, Challenges, and Opportunities for Next‐Generation Inspection

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.

Enabling Under Ice Glider Operations: A Backseat Driver Approach

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Polar Oceans are key locations for forcing global ocean circulation, influencing both global climate and biogeochemical cycles. Due to restricted access to these seasonally and perennially ice‐covered regions, these areas are severely undersampled.

Actuation Strategies for Underwater Jet‐Propelled Soft Robots

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Linear System Identification and Control of a Low‐Cost High‐Performance Omnidirectional Marine Surface Vehicle for Swarming Applications

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.
