The phase relation between sunspot numbers and soft X-ray flares

, 2011
To better understand long-term flare activity, we present a statistical study on soft X-ray flares from May 1976 to May 2008. It is found that the smoothed monthly peak fluxes of C-class, M-class, and X-class flares have a very noticeable time lag of 13,

Bandit: Here to Haunt You! On Why I Became an Émigré Theatre Maker

Meno Istorija ir Kritika, 2019
The article employs concepts of time lag, inspired by Ernst Bloch, and ghost and haunting, borrowed from Jacques Derrida. It also draws on Svetlana Boym’s and Vilém Flusser’s vision of the émigré and on Dominick LaCapra’s and Slavoj Žižek’s ...

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

Computational 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 ...

Dependence of Temporal Properties on Energy in Long-Lag, Wide-Pulse Gamma-Ray Bursts

, 2007
We employed a sample compiled by Norris et al. (2005, ApJ, 625, 324) to study the dependence of the pulse temporal properties on energy in long-lag, wide-pulse gamma-ray bursts.

Time-varying lag cointegration

Journal of Computational and Applied Mathematics, 2021
This paper proposes an alternative estimation method for cointegration, which allows for variation in the leads and lags in the cointegration relation. The method is more powerful than a standard method. Illustrations to annual inflation rates for Japan and the USA and to seasonal cointegration for quarterly consumption and income in Japan shows its ...

The lag-time constraint for behavioural plasticity [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2020
Environmental instability (i.e. environments changing often) can select fixed phenotypes because of the lag time of plastically adapting to environmental changes, known as the lag-time constraint. Because behaviour can change rapidly (e.g. switching between foraging strategies), the lag-time constraint is not considered important for behavioural ...

Hydrological system time lag responses to meteorological shifts

Revista Brasileira de Recursos Hídricos
Hydrological system’s sensibility and resilience to dry periods are crucial for estimating the potential impacts of droughts. Quantifying response times (RT) of this system’s components relative to droughts allows one to develop a predictive ...

The variability of optical \feii emission in PG QSO 1700+518

, 2010
It is found that \feii emission contributes significantly to the optical and ultraviolet spectra of most active galactic nuclei. The origin of the optical/UV \feii emission is still a question open to debate.

Making tau amyloid models in vitro: a crucial and underestimated challenge

FEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Revealing the X-ray source in IRAS 13224-3809 through flux-dependent reverberation lags [PDF]

, 2013
IRAS 13224-3809 was observed in 2011 for 500 ks with the XMM-Newton observatory. We detect highly significant X-ray lags between soft (0.3 - 1 keV) and hard (1.2 - 5 keV) energies. The hard band lags the soft at low frequencies (i.e. hard lag), while the
