Mapping Charge Interactions in Intrinsically Disordered Proteins

Advanced Science, EarlyView.
This study presents analytical models to predict intrachain distances in intrinsically disordered proteins (IDPs), accounting for charge patterning, salt concentration, and electrostatic effects. Validated against single‐molecule FRET data, a minimal‐parameter polymer model is identified that captures key interactions and chain dimensions. These models

A Versatile Three Dimensional Traction Force Microscopy Framework for Uncovering the Mechanics of Bio‐Adhesion

Advanced Science, EarlyView.
This study introduces a versatile platform for quantifying three dimensional traction forces at bio‐adhesive interfaces. Integrating in situ stereo‐digital image correlation with finite element simulations allows for precise measurement of microscale displacements and traction forces in both dry and wet conditions.

Chemical Doping Engineering of Polarization and Topological Textures in van der Waals Ferroelectric CuInP2S6

Advanced Science, EarlyView.
Our work reports that Li⁺ doping in CuInP2S₆ induces coexistence of high‐ and low‐polarization states, which fosters a rich spectrum of topological polar textures, such as bubbles and labyrinth domains. An unconventional flexoelectric effect is also discovered, where strain gradients can mechanically manipulate these polarization states and their ...

Hydroelastic Oscillations of a Circular Plate, Resting on Winkler Foundation

Journal of Physics: Conference Series, 2017
The forced hydroelastic oscillations of a circular plate resting on elastic foundation are investigated. The oscillations are caused by a stamp vibration under interaction with a plate through a thin layer of viscous incompressible liquid. The axis-symmetric problem for the regime of the steady-state harmonic oscillations is considered. On the basis of

Receding contact problem for two elastic layers resting on a Winkler foundation [PDF]

, 2013
In this study, receding contact problem for two elastic layers resting on a Winkler foundation and loaded by means of a rigid circular punch is considered. The elastic layers have different heights and elastic constants. External load is applied to the

The Role of Certifications in Improving Household Food Security Among Peruvian Farmers

Agribusiness, EarlyView.
ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.
