On efficient quantum block encoding of pseudo-differential operators [PDF]

open access: yesQuantum, 2023
Block encoding lies at the core of many existing quantum algorithms. Meanwhile, efficient and explicit block encodings of dense operators are commonly acknowledged as a challenging problem.

The pseudo core inverse of a companion matrix [PDF]

open access: yesStudia Scientiarum Mathematicarum Hungarica, 2018
The notion of core inverse was introduced by Baksalary and Trenkler for a complex matrix of index 1. Recently, the notion of pseudo core inverse extended the notion of core inverse to an element of an arbitrary index in *-rings; meanwhile, it characterized the core-EP inverse introduced by Manjunatha Prasad and Mohana for complex matrices, in terms of ...

Education and Social Fluidity: A Reweighting Approach

open access: yesSociological Science, 2022
Although sociologists have devoted considerable attention to studying the role of education in intergenerational social class mobility using log-linear models for contingency tables, indings in this literature are not free from rescaling or non ...

The pseudo core inverses of differences and products of projections in rings with involution

open access: yesFilomat, 2021
Let R be a unital ring with involution. The pseudo core inverses of differences and products of two projections are investigated in R. Some equivalent conditions are obtained. As applications, the pseudo core invertibility of the commutator pq - qp and the anti-commutator pq + qp are characterized, where p; q are projections in R.

Design and Analysis of a Novel High-Extension Modular Manipulator for Dexterous and Confined-Space Operations

open access: yesIEEE Access
Conventional rigid-link manipulators are ineffective in cluttered and confined environments, such as in-home assistive care or industrial maintenance, which require high dexterity and adaptability.

An adsorption kinetic study of ionic dyes by polyampholyte star polymers

open access: yesHeliyon
The aim of this work was to merge the characteristics of star polymers with polyampholytes to address the issue of treating colored wastewater. To achieve the intended objective, homopolymers derived from acrylic acid were synthesized using reversible ...

A Hybrid Machine Learning Framework for Mechanistically Interpretable Latent Parameter Inference in a Spatiotemporal CAR-T Therapy Model for Solid Tumours

open access: yesTechnologies
CAR-T cell therapy remains ineffective in most solid tumours because effector cells infiltrate poorly, undergo exhaustion, and face antigen escape within an immunosuppressive microenvironment.
