A Compact Three‐Layer VO2‐Integrated Reflective THz Metasurface With Switchable Half‐Wave‐Plate and Quarter‐Wave‐Plate Responses

Advanced Photonics Research
This paper presents a VO2‐integrated reflective switchable polarization conversion metasurface (SPCM) that exploits the insulator‐to‐metal phase transition of vanadium dioxide (VO2) to achieve binary switching between two distinct polarization conversion

Physical Optics and Reflection Locality in Designing Reconfigurable Intelligent Surfaces

IEEE Open Journal of Antennas and Propagation
This paper discusses the applicability conditions of the Physical Optics (PO) approximation and investigates its predictive power for far-field diffraction patterns of Reconfigurable Intelligent Surfaces (RISs) based on binary metasurfaces (BMSs).

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

On the six components of optical angular momentum [PDF]

, 2011
In special relativity the angular momentum is a rank-two antisymmetric tensor with six independent components. Three of these are the familiar generators of spatial rotation, which for light have been studied at length.

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Angular stripe phase in spin-orbital-angular-momentum coupled Bose condensates

, 2020
We propose that a superfluid with supersolidlike properties, i.e., angular stripe phase, can be realized in a pancakelike spin-1/2 Bose gas with spin-orbital-angular-momentum coupling.

FSS bandwidth design using miniaturized elements for angular stability in transmission

, 2022
Frequency-selective surfaces (FSSs) are commonly employed at microwave frequencies in electromagnetic filtering applications. This paper reports the use of cascaded dual miniaturized elements for radio secure environments where miniaturized elements have

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Fano Resonance Enabled by Magnetoelectric Modes for Expanding the Half-Wave Wall Transmission Window under Transverse Electric Polarization

Engineered Science
Despite being one of the most efficient electromagnetic (EM) wave transmission techniques, the conventional half-wave wall suffers from inherent mechanistic limitations that severely constrain its practical performance.

How structural disorder and polyelectrolyte properties of prothymosin α enable its large interactome

FEBS Letters, EarlyView.
In this review, complexes of the fully disordered and highly negatively charged prothymosin α are collected, described, and discussed. Linked to its poly‐electrostatic character, prothymosin α engages a large interactome through multiple different binding modes ranging from fully disordered complexes to short linear motif (SLiM)‐driven interactions ...
