Temporal Disaggregation of Time Series with Regularization Term
Barometr Regionalny, 2016 Methods of temporal disaggregation are used to obtain high frequency time series from the same low frequency time series — so-called disaggregation—with respect to some additional consistency conditions between low and high frequency series.

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

Electronic Notes in Theoretical Computer Science, 2002 AbstractWe propose a new class of rewrite systems that are conservative extensions of first-order conditional term rewrite systems together with time features such as clocks, signals, timed terms, timed atoms and timed rules. We define first timed term rewrite systems by their syntax and illustrate them through some examples.

Homogenization in elastodynamics with force term depending on time
International 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-varying cosmological term [PDF]
Journal of Physics: Conference Series, 2015 We present the case of time-varying cosmological term using the Lagrangian formalism characterized by a scalar field with standard kinetic energy and arbitrary potential V(). This model is applied to Friedmann-Robertson-Walker (FRW)cosmology. Exact solutions of the field equations are obtained by a special ansats to solve the Einstein-Klein-Gordon ...

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

Novel robust time series analysis for long-term and short-term prediction
Scientific Reports, 2021 Nonlinear phenomena are universal in ecology. However, their inference and prediction are generally difficult because of autocorrelation and outliers.

Solutions to viscous Burgers equations with time dependent source term
Electronic Journal of Differential Equations, 2021 We study the existence and uniqueness of weak solutions for a Cauchy problem of a viscous Burgers equation with a time dependent reaction term involving Dirac measure.

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