Combined approach to image coding based on fuzzy classification of fragment

Технологія та конструювання в електронній апаратурі, 2006
The possibility of effective application of fuzzy logic methods in digital image coding and compression tasks is investigated. A new approach is presented that employs discrete cosine transforms and Haar coefficients as a feature space. The efficiency of

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

Advanced Science, EarlyView.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Fast polynomial multiplication and convolutions related to the discrete cosine transform [PDF]

, 1997
A classical scheme for multiplying polynomials is given by the Cauchy product formula. Faster methods for computing this product have been developed using circular convolution and fast Fourier transform algorithms.

PlantGFM: A Genomic Foundation Model for Discovery and Creation of Plant Genes

Advanced Science, EarlyView.
A plant genomic foundation model pre‐trained on 12 species enables both accurate gene prediction and de novo gene design. Through AI‐human knowledge screening, seven designed sequences showed transcriptional activity in plants, with two expressing stable proteins—demonstrating the first DNA‐RNA‐protein expression of LLM‐generated genes in plants and ...

Discrete transforms, semidefinite programming and sum-of-squares representations of nonnegative polynomials [PDF]

, 2006
. We present a new semidefinite programming formulation of sum-of-squares representations of nonnegative polynomials, cosine polynomials and trigonometric polynomials of one variable. The parametrization is based on discrete transforms (specifically, the

The eigenstructure of finite field trigonometric transforms [PDF]

, 2011
In this paper, we discuss the eigenstructure of finite field trigonometric transforms (FFTT). This transform family includes different types of cosine and sine transforms that correspond, in the finite field case, to the well known discrete cosine and ...

Topology‐Aware Deep Learning on Higher‐Order Structures for Drug Response Prediction

Advanced Science, EarlyView.
We present TopDr, a topology‐aware deep learning framework that encodes both drugs and cell lines as multiscale simplicial complexes, capturing interactions at the 0‐, 1‐, and 2‐simplex levels. By jointly integrating local higher‐order neighborhoods and global topological structures, TopDr generates enriched representations for sensitivity prediction ...
