Time Scales and Characteristics of Stock Markets in Different Investment Horizons
Frontiers in Physics, 2020 Investors adopt varied investment strategies depending on the time scales (τ) of short-term and long-term investment time horizons (ITH). The nature of the market is very different in various investment τ.

TIME BOUNDARY TERMS AND DIRAC CONSTRAINTS [PDF]
International Journal of Modern Physics A, 2012 Time boundary terms usually added to action principles are systematically handled in the framework of Dirac's canonical analysis. The procedure begins with the introduction of the boundary term into the integral Hamiltonian action and then the resulting action is interpreted as a Lagrangian one to which Dirac's method is applied.

Arrival Time from Hamiltonian with Non-Hermitian Boundary Term
UniverseIn this study, we developed a new method for finding the quantum probability density of arrival at the detector. The evolution of the quantum state restricted to the region outside of the detector is described by a restricted Hamiltonian that contains a ...

On a generalised model for time-dependent variance with long-term memory
, 2007 The ARCH process (R. F. Engle, 1982) constitutes a paradigmatic generator of stochastic time series with time-dependent variance like it appears on a wide broad of systems besides economics in which ARCH was born.

An Expansion Term In Hamilton's Equations [PDF]
, 1999 For any given spacetime the choice of time coordinate is undetermined. A particular choice is the absolute time associated with a preferred vector field. Using the absolute time Hamilton's equations are $- (\delta H_{c})/(\delta q)=\dot{\pi}+\Theta\pi,

Pediatric Blood &Cancer, EarlyView.ABSTRACT We sought to identify potential early risk biomarkers for lung disease in children post‐allogeneic HCT. Patients with pulmonary function tests 3 months post‐transplant and plasma samples between days 7 and 14 post‐HCT were included. Six of 27 subjects enrolled had reduced forced expiratory volume 1 (FEV1) z scores.

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

Integrating term-time working into graduate employability development strategies [PDF]
, 2002 Government at the time of this project was seeking to improve graduate employability. With work placements for undergraduates struggling to keep up with the expansion in student numbers, term-time working can potentially provide a significant source of ...

Long-term Recall of Time to Pregnancy [PDF]
Epidemiology, 2016 Despite the widespread use of retrospectively reported time to pregnancy to evaluate fertility either as an outcome or as a risk factor for chronic disease, only two small studies have directly compared prospective data with later recall.The North Carolina Early Pregnancy Study (1982-1986) collected prospective time-to-pregnancy data from the beginning
