Stochastic Locomotion Emerging From Body–Environment Interactions in a Mexican Jumping Bean–Inspired Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...

Diagnosing the system: Mental health, necropolitical uncare, and the abolition of migration detention

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This article examines the psychological effects of migration detention in the European Union's Closed Controlled Access Center (CCAC) on Samos through an ecological lens. It explores a double normalization of suffering: the brutalization of necropolitical migration governance and the simultaneous understanding of resulting distress as an ...

Extracting winter North Atlantic Oscillation information from a central European stalagmite [PDF]

open access: yes, 2013
This study explores the potential for extracting winter North Atlantic Oscillation (NAO) information from central European stalagmites using a high resolution calcite δ18O (δ18Ocal) time-series from a stalagmite (AH1) extracted from Atta cave in ...

Unexpectedly Strong Electrostatic Screening in Nano‐Ion Solutions

open access: yesAngewandte Chemie International Edition, EarlyView.
Colloidal probe AFM measurements reveal unexpectedly strong electrostatic screening in aqueous solutions of the polyoxometalates phosphotungstate [PW12O40]3−${[{\rm PW}_{12}{\rm O}_{40}]}^{3-}$ and silicotungstate [SiW12O40]4−$[{\rm SiW}_{12}{\rm O}_{40}]^{4-}$.

Compensation phenomena in geometric partial differential equations [PDF]

open access: yes
In this thesis we present optimal and improved estimates for systems of critical elliptic PDE which arise as generalisations of natural geometric problems.

Linear Viscoelastic Behavior of n‐Alkane Diluted Polyethylene Melts: Sorption, Desorption, and Oscillatory Rheometry

open access: yesJournal of Applied Polymer Science, EarlyView.
This study systematically maps polyolefin dilution dynamics using a homologous series of n‐alkanes. Integrating gravimetric sorption, subsequent controlled desorption, and oscillatory rheometry establishes a precise framework to analyze reduction in viscosity at least for polymer diluent mixtures with polymer concentration > 35% and diluent ...

Comparative assessment of volume‐of‐fluid (VOF) multiphase solvers for viscoplastic flow over grooved patterned surfaces

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Accurately simulating multiphase flows at low capillary numbers remains challenging due to spurious currents and interface discretization errors. We present a systematic comparison of four volume‐of‐fluid (VOF) solvers within the OpenFOAM framework for pressure‐driven Poiseuille–Bingham flow over grooved surfaces: interFoam with classical ...

Numerical simulation of flow past a cylinder in orbital motion [PDF]

open access: yes, 2004
A finite difference solution is presented for 2D laminar unsteady flow around a circular cylinder in orbital motion placed in a uniform flow for Re = 130, 160, and 180. Four cases displaying full lock-in are presented.
