Swimming exercise improves short‐ and long‐term memories: Time‐course changes

open access: yesPhysiological Reports, 2021
The beneficial effects of exercise training on memory formation are well documented. However, the memory enhancement profile following the time‐course of exercise training remains unknown.

Lower bounds for blow up time of the p-Laplacian equation with damping term [PDF]

open access: yesMathematica Moravica, 2021
In this work deals with the p-Laplacian wave equation with damping terms in a bounded domain. Under suitable conditions, we obtain a lower bounds for the blow up time.

Synchronizations of fuzzy cellular neural networks with proportional time-delay

open access: yesAIMS Mathematics, 2021
In this article, finite-time and fixed-time synchronizations (FFTS) of fuzzy cellular neural networks (FCNNs) with interaction and proportional delay terms have been investigated.

Time lags: insights from the U.S. Long Term Ecological Research Network

open access: yesEcosphere, 2021
Ecosystems across the United States are changing in complex ways that are difficult to predict. Coordinated long‐term research and analysis are required to assess how these changes will affect a diverse array of ecosystem services.

Short Term Forecast of COVID-19 cases in Japan Using Time Series Analysis Models

open access: yesJournal of Computing Research and Innovation, 2022
The new strain of coronavirus (COVID-19) was found to have started in Wuhan, China in late December 2019. The virus has spread to countries all over the world including Japan.

Identification of short-term and long-term time scales in stock markets and effect of structural break [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, Volume 545, 1 May 2020, 123612, 2019
The paper presents the comparative study of the nature of stock markets in short-term and long-term time scales with and without structural break in the stock data. Structural break point has been identified by applying Zivot and Andrews structural trend break model to break the original time series (TSO) into time series before structural break (TSB ...

Novel robust time series analysis for long-term and short-term prediction

open access: yesScientific Reports, 2021
Nonlinear phenomena are universal in ecology. However, their inference and prediction are generally difficult because of autocorrelation and outliers.

Homogenization in elastodynamics with force term depending on time

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We extend the study on the homogenization problem for an elastic material containing a distributed array of gas bubbles to the case when the body force depends on time.

Time continuum and true long-term ecology: from theory to practice

open access: yesFrontiers in Ecology and Evolution, 2014
The need for long-term studies to understand ecological dynamics is widely recognised but has not been satisfactorily addressed to date. The development of long-term (LT) observatories has aimed to improve the situation, but the main handicaps are that ...

Integrating Long and Short‐Term Time Dependencies in Simulation‐Based Seismic Hazard Assessments

open access: yesEarth and Space Science, 2022
Conventional probabilistic seismic hazard analysis (PSHA) only considers mainshock events and uses a time‐independent earthquake rupture forecast to describe the occurrence of mainshocks. This approach neglects the long‐term time‐dependency of mainshocks
