Delay-independent stability in bidirectional associative memory networks [PDF]

open access: yes, 1994
It is shown that if the neuronal gains are small compared with the synaptic connection weights, then a bidirectional associative memory network with axonal signal transmission delays converges to the equilibria associated with exogenous inputs to the ...

Predictors and pathway of maternal near miss: A case–control study in a tertiary care facility in Kolkata

open access: yesIndian Journal of Community Medicine, 2022
Background: Use of maternal near-miss (MNM) cases as an adjunct has been advocated to understand the processes of obstetric care because they share similar pathways as maternal deaths. Identifying the predictors and care pathway is crucial to improve the

Bifurcation analysis for a delayed SEIR epidemic model with saturated incidence and saturated treatment function

open access: yesJournal of Biological Dynamics, 2019
A delayed SEIR epidemic model with saturated incidence and saturated treatment function is considered in this paper. Sufficient conditions for the existence of local Hopf bifurcation are established by regarding the possible combination of the two delays

Responsiveness of emergency obstetric care systems in low- and middle-income countries: a critical review of the "third delay". [PDF]

open access: yes, 2012
We reviewed the evidence on the duration, causes and effects of delays in providing emergency obstetric care to women attending health facilities (the third delay) in low- and middle-income countries. We performed a critical literature review using terms

Oscillation Theory for Non-Linear Neutral Delay Differential Equations of Third Order

open access: yesApplied Sciences, 2020
In this article, we study a class of non-linear neutral delay differential equations of third order. We first prove criteria for non-existence of non-Kneser solutions, and criteria for non-existence of Kneser solutions.

Delayed access to innovative medicines in Romania: a comprehensive analysis of the reimbursement processes (2015–2024)

open access: yesFrontiers in Public Health
IntroductionRomania’s reimbursement framework for innovative medicines relies on health technology assessments (HTAs) resulting in unconditional or conditional decisions. Although conditional decisions aim to manage financial uncertainty via Cost-Volume (
