Facial expression recognition using singular values and wavelet‐based LGC‐HD operator
IET Biometrics, 2021 Facial expression recognition (FER) is a significant research area in the human–computer interaction. The performance of FER systems depends on an efficient feature extraction method.

The Veneziano amplitude via mostly BRST exact operator
Nuclear Physics B, 2022 The Veneziano amplitude is derived from fixing one degree of freedom of PSL(2,R) symmetry by the insertion of a mostly BRST exact operator. Evaluating the five-point function which consists of four open string tachyons and this gauge fixing operator, we ...

Expressive Power and Intensional Operators
Journal of Logic, Language and InformationAbstractIn Entities and Indices, M. J. Cresswell argued that a first-order modal language can reach the expressive power of natural-language modal discourse only if we give to the formal language a semantics with indices containing infinite possible worlds and we add to it an infinite collection of operators $${{\varvec{actually}}}_n$$

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.

Spectrums of Solvable Pantograph Differential-Operators for First Order
Abstract and Applied Analysis, 2014 By using the methods of operator theory, all solvable extensions of minimal operator generated by first order pantograph-type delay differential-operator expression in the Hilbert space of vector-functions on finite interval have been considered.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Operator Sequence Alters Gene Expression Independently of Transcription Factor Occupancy in Bacteria
Cell Reports, 2012 A canonical quantitative view of transcriptional regulation holds that the only role of operator sequence is to set the probability of transcription factor binding, with operator occupancy determining the level of gene expression.

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 ...

On an approximation operator and its Lipschitz constant
Journal of Numerical Analysis and Approximation Theory, 2002 In this note we consider an approximation operator of Kantorovich type in which expression appears a basic sequence for a delta operator and a Sheffer sequence for the same delta operator.
