The provision of informal care in terminal illness: An analysis of carers? needs using a discrete choice experiment [PDF]

open access: yes
There is an increasing expectation that families will provide care at home for those with chronic, acute and terminal illness. There is a range of services available to support the home care of these patients.

Wearable Morphology‐Adaptive in‐Ear Device With Active Cleansing Capability for Multimodal Health Monitoring

open access: yesAdvanced Materials, EarlyView.
We present SCIENCE, an in‐ear multimodal physiological monitor featuring two key innovations. Water‐triggered morphological expansion (a 2‐mm cylinder to a 9‐mm spindle) achieves conformal adaptation across complex canal geometries. Simultaneously, active biofouling mitigation disrupts cerumen barriers, reducing sensor‐skin impedance by 20%.

Fast Hydrogel Micro‐Actuators Driven by Electric Fields

open access: yesAdvanced Materials, EarlyView.
We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...

Ordering effects and strategic response in discrete choice experiments [PDF]

open access: yes
This study explores ordering effects and response strategies in repeated binary discrete choice experiments (DCE). Mechanism design theory and empirical evidence suggest that repeated choice tasks per respondent introduce strategic behavior.

Wavelength‐ and Helicity‐Reconfigurable Circularly Polarized Optical Diodes Enabled by Molecular Photoswitches

open access: yesAdvanced Materials, EarlyView.
All‐optical, photoswitchable diode‐type device for tunable nonreciprocal (asymmetric) transmission of CPL across a broad spectrum of light is demonstrated using molecular motor (photoswitch)‐doped cholesteric liquid crystals (CLCs) sandwiched between polyvinyl alcohol (PVA) and polydopamine (PDA)‐PVA composite layers.

Discrete mathematics in the high school curriculum

open access: yes, 2004
In this paper we present some topics from the field of discrete mathematics which might be suitable for the high school curriculum. These topics yield both easy to understand challenging problems and important applications of discrete mathematics.

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

open access: yesAdvanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Morphological Characterization of Spherulites in Silk‐Polycaprolactone Mixtures: Implications for Textured Materials

open access: yesAdvanced Materials Interfaces, EarlyView.
Blending silk fibroin with polycaprolactone alters crystalline organization and surface morphology. Low fibroin levels promote ring‐banded spherulites, while higher contents generate porous, pit‐like textures, though overall crystallinity remains unchanged. Solvent evaporation further modulates surface patterns.

An hp-version discontinuous Galerkin method for integro-differential equations of parabolic type [PDF]

open access: yes, 2011
We study the numerical solution of a class of parabolic integro-differential equations with weakly singular kernels. We use an $hp$-version discontinuous Galerkin (DG) method for the discretization in time.

Tailoring Iron Nanostructures on MoS2: The Pivotal Role of Sulfur Vacancies in Growth Morphology and Charge Transfer

open access: yesAdvanced Materials Interfaces, EarlyView.
The deposition of Iron on pristine MoS2/Au(111) monolayers produces nanoparticles that donate charge to the support, generating Fe+2‐interfacial species. On the contrary, on defect‐engineered MoS2, sulfur vacancies trap sub‐nanometric Fe clusters and host two excess electrons that redistribute locally, suppressing Fe oxidation without formal Mo ...
