AIP Advances, 2012 We report X-ray resonant magnetic scattering studies of a Permalloy artificial square ice nanomagnet array, focussing on the field-driven evolution of the sum Σ and difference Δ signals of left and right handed circularly polarized synchrotron X-rays at ...

The picture plane and its transformation. Some remarks on Jerzy Wolff’s idea of a picture
, 2017 This article presents JerzyWolff’s understanding of the picture plane. For Wolff this plane is a special object which transforms its “face”: from a physical surface into an artistic and finally aesthetic space.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Picture-plane inversion leads to qualitative changes of face perception
Acta Psychologica, 2008 Presenting a face stimulus upside-down generally causes a larger deficit in perceiving metric distances between facial features ("configuration") than local properties of these features. This effect supports a qualitative account of face inversion: the same transformation affects the processing of different kinds of information differently.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Tunable exciton valley-pseudospin orders in moiré superlattices
Nature CommunicationsExcitons in two-dimensional (2D) semiconductors have offered an attractive platform for optoelectronic and valleytronic devices. Further realizations of correlated phases of excitons promise device concepts not possible in the single particle picture ...

An improved Dijkstra cross-plane image encryption algorithm based on a chaotic system
Frontiers in Artificial IntelligenceWhile encrypting information with color images, most encryption schemes treat color images as three different grayscale planes and encrypt each plane individually. These algorithms produce more duplicated operations and are less efficient because they do

Direct Visualization of the Nematic Superconductivity in Cu_{x}Bi_{2}Se_{3}
Physical Review X, 2018 Cu_{x}Bi_{2}Se_{3} hosts both topological surface states and bulk superconductivity. It has been identified recently as a topological superconductor (TSC) with an extraordinary nematic, i.e., C_{2}-symmetric superconducting state and odd-parity pairing ...

MEMS Deformable Mirrors for Space-Based High-Contrast Imaging
Micromachines, 2019 Micro-Electro-Mechanical Systems (MEMS) Deformable Mirrors (DMs) enable precise wavefront control for optical systems. This technology can be used to meet the extreme wavefront control requirements for high contrast imaging of exoplanets with coronagraph

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
