AN ALGORITHM OF ADAPTIVE LIFTING WAVELET TRANSFORM COMPUTATION based on prediction error diffusion

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
An algorithm of adaptive lifting wavelet transform computation based on adaptive prediction of the detail wavelet coefficients, with using subbands halftone image obtained from the original grayscale is proposed. The results of an algorithm modeling show

Mesh Processing Non‐Meshes via Neural Displacement Fields

Computer Graphics Forum, EarlyView.
Abstract Mesh processing pipelines are mature, but adapting them to newer non‐mesh surface representations—which enable fast rendering with compact file size—requires costly meshing or transmitting bulky meshes, negating their core benefits for streaming applications.

An investigative study of multispectral data compression for remotely-sensed images using vector quantization and difference-mapped shift-coding [PDF]

A study is conducted to investigate the effects and advantages of data compression techniques on multispectral imagery data acquired by NASA's airborne scanners at the Stennis Space Center. The first technique used was vector quantization.

The MacBrain Resource Center (MBRC) rhesus macaque embryonic brain histology datasets

Journal of Anatomy, EarlyView.
We introduce the MacBrain Resource Center (MBRC) Collections of rhesus macaque embryonic brain tissue. Here, we illustrate histo‐ and immunohistology from our dynamically growing Collection 6, which currently contains >10,000 zoomable and downloadable images from n = 14 male and female embryos from early to late in gestation.

High-Speed Architecture for Hybrid Arithmetic–Huffman Data Compression

Technologies
This paper proposes a hardware–software co-design for adaptive lossless compression based on Hybrid Arithmetic–Huffman Coding, a table-driven approximation of arithmetic coding that preserves near-optimal compression efficiency while eliminating the ...

Resolving Isomeric Structures in Natural Complex Carbohydrates: A Comparative Study of SLIM and Cyclic Ion Mobility Platforms

Rapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Recent advances in ion mobility mass spectrometry (IMS) have led to the development of high‐resolution platforms such as cyclic IMS and SLIM IMS (structures for lossless ion manipulations), both offering enhanced capabilities for resolving complex biomolecular conformations.

Giant Circular Dichroism in Chiral Broad Flat‐Band Quasi‐BIC Metasurface

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Tuning the near‐field coupling between adjacent nanopillars gradually flattens the photonic band. Reducing the interpillar spacing strengthens mode hybridization, yielding an ultraflat dispersion that hosts a high‐Q quasi‐BIC. This work delineates the physical mechanism linking structural parameters to flat‐band formation, enabling giant circular ...

Long‐Range Polariton Canalization in a Graphene‐Nanoribbon–Covered MgTeMoO6 Metasurface

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Simulated Re(Ez) field distributions at ω = 924 cm−1 for the graphene grating, MgTeMoO6 grating, the proposed hybrid structure, and the corresponding IFCs in (kx, ky) space are shown. Re(Ez) field maps in the x–y plane at ω = 924 cm−1 for Ef = 50, 70, 74, 76, 80, and 88 meV.

Reconfigurable Analog Computing Metasurfaces Based on Thin Film Lithium Niobate

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
A transmissive reconfigurable analog computing metasurface based on a simple TFLN structure is demonstrated. The proposed metasurface is truly flexible and capable of switching between different computing functions, such as first‐order differentiation, second‐order differentiation, and integration.
