Synchronization of cardiorhythm by weak external forcing

Discrete Dynamics in Nature and Society, 2000
We study the possibility to synchronize cardiorhythm of a human by periodic and aperiodic sequences of light and sound pulses. Aperiodic forcing is defined by variation of RR intervals of another subject.

The role of internal variability and external forcing on southwestern Australian rainfall: prospects for very wet or dry years. [PDF]

Sci Rep, 2023
The cool-season (May to October) rainfall decline in southwestern Australia deepened during 2001–2020 to become 20.5% less than the 1901–1960 reference period average, with a complete absence of very wet years (i.e., rainfall > 90th percentile).

Radiative forcing in the 21st century due to ozone changes in the troposphere and the lower stratosphere [PDF]

, 2003
Radiative forcing due to changes in ozone is expected for the 21st century. An assessment on changes in the tropospheric oxidative state through a model intercomparison ("OxComp'') was conducted for the IPCC Third Assessment Report (IPCC-TAR).

Radiative forcing since preindustrial times due to ozone change in the troposphere and the lower stratosphere [PDF]

, 2006
Changes in atmospheric ozone have occurred since the preindustrial era as a result of increasing anthropogenic emissions. Within ACCENT, a European Network of Excellence, ozone changes between 1850 and 2000 are assessed for the troposphere and the lower ...

Stochastic forcing of the Lamb–Oseen vortex [PDF]

, 2008
The aim of the present paper is to analyse the dynamics of the Lamb–Oseen vortex when continuously forced by a random excitation. Stochastic forcing is classically used to mimic external perturbations in realistic configurations, such as variations of ...

Aerosol modeling over Europe: 2. Interannual variability of aerosol shortwave direct radiative forcing [PDF]

, 2007
Aerosol distribution over Europe and its direct radiative forcing have been simulated with a regional atmosphere-chemistry model and an off-line radiation transfer model. Primary and secondary organic and inorganic aerosols have been considered.

Observations of diurnal and spatial variability of radiative forcing by equatorial deep convective clouds [PDF]

, 2004
From geostationary satellite observations of equatorial Africa and the equatorial east Atlantic during May and June 2000 we explore the radiative forcing by deep convective cloud systems in these regions. Deep convective clouds (DCCs) are associated with

On the Link Between Global Volcanic Activity and Global Mean Sea Level

Frontiers in Earth Science, 2022
Studying a large number of volcanic eruptions is a way to decipher general characteristics related to volcano dynamics but also on external forcing influencing it, such as solid Earth and ocean tides. Many studies have tackled this tidal influence on the

A novel statistical decomposition of the historical change in global mean surface temperature

Environmental Research Letters, 2021
According to the characteristics of forced and unforced components to climate change, sophisticated statistical models were used to fit and separate multiple scale variations in the global mean surface temperature (GMST) series.

Major factors of global and regional monsoon rainfall changes: natural versus anthropogenic forcing

Environmental Research Letters, 2020
A number of studies have investigated the mechanisms that determine changes in precipitation, including how a wet region gets wetter. However, not all monsoon areas get wetter—there is a need to understand the major factors behind changes in regional ...
