Term structure transmission of monetary policy [PDF]
, 2007 Under bond rate transmission of monetary policy, standard restrictions on policy responses to obtain determinate inflation need not apply. In periods of passive policy, bond rates may exhibit stable responses to inflation if future policy is anticipated ...

Incorporating geostrophic wind information for improved space-time short-term wind speed forecasting [PDF]
, 2014 Accurate short-term wind speed forecasting is needed for the rapid development and efficient operation of wind energy resources. This is, however, a very challenging problem. Although on the large scale, the wind speed is related to atmospheric pressure,

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 ...

Mixed gauge-gravity term and proper time
Physics Letters BWe consider the four-dimensional action of spinors minimally coupled to a U(1) gauge field on a Riemann-Cartan background. In this theory, we integrate over the spinors and study the resulting one-loop gauge-gravity effective action, paying special ...

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.

Recurrence time analysis, long-term correlations, and extreme events
, 2005 The recurrence times between extreme events have been the central point of statistical analyses in many different areas of science. Simultaneously, the Poincar\'e recurrence time has been extensively used to characterize nonlinear dynamical systems.

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.

TAFFNet: Time‐Aware Adaptive Feature Fusion Network for Very Short‐Term Precipitation Forecasts
Geophysical Research Letters, 2023 Deep learning models based on radar echo extrapolation have been widely used in precipitation nowcasting. However, they face the challenge of insufficient input information when extending the forecast lead time, requiring the incorporation of physics ...

Lost in Time: Temporal Analytics for Long-Term Video Surveillance
, 2017 Video surveillance is a well researched area of study with substantial work done in the aspects of object detection, tracking and behavior analysis. With the abundance of video data captured over a long period of time, we can understand patterns in human

Unitary Matrix Models with a topological term and discrete time Toda equation [PDF]
, 1996 We study the full unitary matrix models. Introducing a new term $l log U$, l plays the role of the discrete time. On the other hand, the full unitary matrix model contains a topological term. In the continuous limit it gives rise to a phase transition at
