Time Lag to Diagnosis of Stroke

open access: yesPediatric Neurology Briefs, 2002
Time to diagnosis was determined in 41 children, 0 to 18 years, with ischemic or hemorrhagic stroke documented prospectively or by retrospective chart review of the last 2 years database, at State University of New York, Stony Brook, NY.

An Effective Optimization Approach to Minimize Waste in a Complex Industrial System

open access: yesIEEE Access, 2022
Industrial waste is a major environmental concern. This paper proposes an optimization approach to better manage the operations of a food production line, with the aim of minimizing material waste.

Delay time modulation induced oscillating synchronization and intermittent anticipatory/lag and complete synchronizations in time-delay nonlinear dynamical systems [PDF]

open access: yes, 2007
Existence of a new type of oscillating synchronization that oscillates between three different types of synchronizations (anticipatory, complete and lag synchronizations) is identified in unidirectionally coupled nonlinear time-delay systems having two ...

Reliable numerical treatment with Adams and BDF methods for plant virus propagation model by vector with impact of time lag and density

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
Plant disease incidence rate and impacts can be influenced by viral interactions amongst plant hosts. However, very few mathematical models aim to understand the viral dynamics within plants.

The flux-dependent X-ray time lags in NGC 4051 [PDF]

open access: yes, 2013
We present an analysis of the X-ray time lags for the highly variable Seyfert 1 galaxy NGC 4051, based on a series of XMM-Newton observations taken in 2009. We investigate the Fourier frequency dependent time lags in the light curves between the 0.3--1.0

The Relationship between Monetary Aggregates and Inflation – the Case of the Czech Republic [PDF]

open access: yesStatistika: Statistics and Economy Journal, 2023
Based on empirical data, this paper attempts modelling, in general terms, the relationship between money supply and inflation, i.e., the relationship between the inflation rate and monetary aggregates.

Transition from anticipatory to lag synchronization via complete synchronization in time-delay systems [PDF]

open access: yes, 2005
The existence of anticipatory, complete and lag synchronization in a single system having two different time-delays, that is feedback delay $\tau_1$ and coupling delay $\tau_2$, is identified.

Experimental determination of time lag and decrement factor

open access: yesCase Studies in Construction Materials, 2019
Buildings consume about 40% of the primary energy in the world. This means that buildings are responsible for the majority of greenhouse gas emissions. It’s time to reduce this energy consumption to limit the environmental impact of buildings. The use of

Time lag analysis of novel arithmetic modeling in breast cancer [PDF]

open access: yesComputational Ecology and Software, 2021
In this paper, a mathematical model which considers population dynamics among infected and uninfected cancer tumor cells has been proposed. Delay differential equations have been utilized to demonstrate the framework to consider the periods of the cell ...

The changing X-ray time lag in MCG-6-30-15 [PDF]

open access: yes, 2014
MCG-6-30-15 is one of the most observed Narrow Line Seyfert 1 galaxies in the X-ray band. In this paper we examine the X-ray time lags in this source using a total of 600 ks in observations (440 ks exposure) taken with the XMM-Newton telescope (300 ks in
