Terahertz Encryption With a Polarization‐Sensitive Metasurface

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
We propose a dual‐functional terahertz encryption metasurface that enables independent information retrieval in both the near field and the far field within a single device. In the near field, polarization‐selective amplitude modulation reveals textual patterns, whereas in the far field, phase engineering encodes multiple digital data in focal‐spot ...

Diverse Genetic Etiologies of Unilateral Polymicrogyria

open access: yesAnnals of Neurology, Volume 99, Issue 5, Page 1277-1286, May 2026.
Objective Polymicrogyria (PMG) is one of the most common human malformations of cortical development and is often classified by its radiographic pattern of distribution. Unilateral polymicrogyria (uPMG) is a subtype of PMG affecting a portion or all of one cerebral hemisphere.

Black in Impressionism and Post‐Impressionism: Art, Color Vision, and Psychophysics

open access: yesColor Research &Application, Volume 51, Issue 3, May/June 2026.
Black has engendered controversy in 19th Century color theory and in Impressionist and Post‐Impresssionist painting. The neural mechanisms of blackness perception are being revealed through contemporary psychophysics. ABSTRACT From Paleolithic cave art to modern abstraction, artists have used black not merely as a neutral tone, but as a powerful ...

Bipolar photovoltaic effect in InSe/MoO3 van der Waals heterostructure for spontaneous light polarization detection

open access: yesInfoMat, Volume 8, Issue 5, May 2026.
Bidirectional photo response in a two‐dimensional heterojunction photodetector controlled by light wavelength and polarization. Abstract Polarization is one of the most fundamental properties of light. Traditional polarization‐sensitive photodetectors, however, are limited in their ability to fully extract this information, as they translate the two ...

Adaptive Orthogonal Frequency Division Multiplexing Schemes

open access: yes, 1998
This paper investigates the upper-bound performance of subband-adaptive Orthogonal Frequency Division Multiplexing (OFDM) transmission in a time-dispersive channel and the feasibility of blind modulation scheme detection algorithms not requiring modulation scheme signalling information.

Spectral Efficiency for Orthogonal Frequency Division Multiplexing

open access: yesInternational Journal of Advanced Research in Science, Communication and Technology
Orthogonal Frequency Division Multiplexing (OFDM) is a special form of multicarrier modulation (MCM) with heavily spaced subcarriers as well as overlapping spectra was patented in the United States of America in 70s. Orthogonal Frequency Division Multiplexing has been popularly utilized in modern days due to its ability for spectral efficiency and ...

Pupil Plane Multiplexing for Vectorial Fourier Ptychography

open access: yesLaser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.
This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.

Single‐Cell Nanodroplet Processing Proteomics Pipeline for Analysis of Human‐Derived Microglia

open access: yesPROTEOMICS, Volume 26, Issue 5, Page 59-68, May 2026.
ABSTRACT Single‐cell omics tools provide unique insights into heterogeneous cell populations and their responses to stimuli. For example, single‐cell RNA sequencing has identified several transcriptionally distinct populations of microglia, which are resident immune cells of the central nervous system (CNS) that are responsive to CNS injury, infection,
