Absense of slow transients, and the effect of imperfect vertical alignment, in turbulent Rayleigh-Benard convection

open access: yes, 2005
We report experimental results for the influence of a tilt angle beta relative to gravity on turbulent Rayleigh-Benard convection of cylindrical samples.

Noël Coward and the Sitwells: enmity, celebrity, popularity [PDF]

open access: yes, 2015
In 1923, the year of the first public performance of Edith Sitwell and William Walton's Façade, Noël Coward satirized the Sitwell siblings in his sketch “The Swiss Family Whittlebot.” The result was an enduring feud between Coward and the Sitwells that ...

Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

Computation of melting with natural convection inside a rectangular enclosure heated by discrete protruding heat sources

open access: yesApplied Mathematical Modelling, 2013
Abstract This paper presents the results of a numerical investigation of the heat transfer by natural convection during the melting of a phase change material (PCM, n -eicosane with melting point of 36 °C) contained in a rectangular enclosure. This latest is heated by three discrete protruding heat sources (simulating electronic components) placed ...

Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Implementation of Drug‐Induced Rhabdomyolysis and Acute Kidney Injury in Microphysiological System

open access: yesAdvanced Functional Materials, EarlyView.
A modular Muscle–Kidney proximal tubule‐on‐a‐chip integrates 3D skeletal muscle and renal proximal tubule tissues to model drug‐induced rhabdomyolysis and acute kidney injury. The coculture system enables dynamic tissue interaction, functional contraction monitoring, and quantification of nephrotoxicity, revealing drug side effect‐induced metabolic ...

Postalveolar fricatives in Slavic languages as retroflexes [PDF]

open access: yes, 2002
The present study poses the question on what phonetic and phonological grounds postalveolar fricatives in Polish can be analyzed as retroflex and whether postalveolar fricatives in other Slavic languages are retroflex as well.

Charge‐Induced Morphing Gels for Bioinspired Actuation

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...

Electroactive Liquid Crystal Elastomers as Soft Actuators

open access: yesAdvanced Functional Materials, EarlyView.
Electroactive liquid crystal elastomers (eLCEs) can be actuated via electromechanical, electrochemical, or electrothermal effects. a) Electromechanical effects include Maxwell stress, electrostriction, and the electroclinic effect. b) Electrochemical effects arise from electrode redox reactions.
