On the band functions and Bloch functions

open access: yesTurkish Journal of Mathematics, 2023
In this paper, we consider the continuity of the band functions and Bloch functions of the differential operators generated by the differential expressions with periodic matrix coefficients.

Dental Poly(methyl methacrylate)-Based Resin Containing a Nanoporous Silica Filler

open access: yesJournal of Functional Biomaterials, 2022
Poly(methyl methacrylate) (PMMA)-based resins have been conventionally used in dental prostheses owing to their good biocompatibility. However, PMMA-based resins have relatively poor mechanical properties.

Generalised Functions as Linear Functionals on Generalized Functions [PDF]

open access: yes, 1984
We give a sketch of a rigorous foundation for the model for a symmetrical theory of generalised functions introduced earlier by the second author. On starting with a suitable subspace PC of the space S’ of tempered distributions, we introduce a space SGF of “new” generalised functions as a space of linear functionals on PC.

Multiplicative functionals on function Algebras

open access: yesRevista Matemática Complutense, 1988
It is in general of interest to identify certain characters of the algebra A of all real analytic or real \(C^ n\)-functions on some real Banach space E as point evaluations at some point of E. The authors prove a general theorem in this direction. Some applications of this theorem are cases where every character is the point evaluation.

Bayesian function‐on‐function regression for multilevel functional data [PDF]

open access: yesBiometrics, 2015
SummaryMedical and public health research increasingly involves the collection of complex and high dimensional data. In particular, functional data—where the unit of observation is a curve or set of curves that are finely sampled over a grid—is frequently obtained.

Identifying key environmental barriers experienced by persons with mild, moderate, or severe disability in Bankim Health District, Cameroon: a policy-targeted secondary analysis of data obtained with the World Bank and WHO model disability survey

open access: yesArchives of Public Health, 2021
Background Comprehensive data is key for evidence-informed policy aiming to improve the lives of persons experiencing different levels of disability.

Indole Diterpene Derivatives from the Aspergillus flavus GZWMJZ-288, an Endophytic Fungus from Garcinia multiflora

open access: yesMolecules, 2023
A new indole diterpene, 26-dihydroxyaflavininyl acetate (1), along with five known analogs (2–6) were isolated from the liquid fermentation of Aspergillus flavus GZWMJZ-288, an endophyte from Garcinia multiflora.

Dangerous demographics in post-bleach corals reveal boom-bust versus protracted declines

open access: yesScientific Reports, 2021
Thermal-stress events have changed the structure, biodiversity, and functioning of coral reefs. But how these disturbances affect the dynamics of individual coral colonies remains unclear.

Determination of a Wave Function Functional [PDF]

open access: yesPhysical Review Letters, 2004
In this paper we propose the idea of expanding the space of variations in standard variational calculations for the energy by considering the wave function $ψ$ to be a functional of a set of functions $χ: ψ= ψ[χ]$, rather than a function. In this manner a greater flexibility to the structure of the wave function is achieved.
