CMOS‐Integrated Synaptic Photoreceptor Chip Inspired by Insect Visual Processing
Advanced Science, EarlyView.CMOS‐integrated Si QDs/ReS2 synaptic photoreceptor array mimics the parallel processing and wavelength‐selective strategy of insect vision. By combining intrinsic ultraviolet‐violet sensitivity with synaptic plasticity, the chip enables frontend sensory redundancy reduction without external filters, offering a scalable pathway toward lowpower ...

Some aspects of Isbell-convex quasi-metric spaces
Applied General Topology, 2018 We introduce and investigate the concept of geodesic bicombing in T0-quasi-metric spaces. We prove that any Isbell-convex T0-quasi-metric space admits a geodesic bicombing which satisfies the equivariance property.

Some Reciprocal Classes of Close-to-Convex and Quasi-Convex Analytic Functions
Mathematics, 2019 The present paper comprises the study of certain functions which are analytic and defined in terms of reciprocal function. The reciprocal classes of close-to-convex functions and quasi-convex functions are defined and studied.

On Non-hyperbolic Quasi-convex Spaces [PDF]
Transactions of the American Mathematical Society, 1998 We show that if the universal covering of a compact Riemannian manifold with no conjugate points is a quasi-convex metric space then the following assertion holds: Either the universal covering of the manifold is a hyperbolic geodesic space or it contains a quasi-isometric immersion of

On the Coefficients of Quasi-Convex Functions
Journal of Physics: Conference Series, 2020 Abstract In this paper we introduce and investigate the class of T (λ, β, A, B) that we call the class of quasi-starlike and quasi-convex functions with respect to the values of the parameter λ. Also we define the class K (λ, β, µ, m, A, B) which is satisfy non-homogeneous Cauchy-Euler differential equation.

Advanced Science, EarlyView.Defect‐configurational origins of the asymmetric apparent electrostrain are revealed in different piezoelectric ceramics via atomic‐scale visualization of defect configurations. Migration of oxygen vacancies leads to the electrobending effect in N2‐sintered BaTiO3, while defect dipoles in Ba0.99TiO2.99 generate true asymmetric electrostrain without ...

Angewandte Chemie, EarlyView.We report on a suitable approach to predict the chirality “strength” and efficacy of chirality transfer from chiral nanoshape solutes to an achiral discotic nematic (ND) liquid crystal solvent. Highly efficacious chirality transfer based on shape commensurability between nanoshape solute (in the form of gold nanodiscs, GNDs) and a ND solvent was ...

Completeness properties of locally quasi-convex groups [PDF]
, 2001 It is natural to extend the Grothendieck theorem on completeness, valid for locally convex topological vector spaces, to Abelian topological groups. The adequate framework to do it seems to be the class of locally quasi-convex groups.
