Understanding AMOC stability: the North Atlantic Hosing Model Intercomparison Project [PDF]
Geoscientific Model Development, 2023 The Atlantic meridional overturning circulation (AMOC) is an important part of our climate system. The AMOC is predicted to weaken under climate change; however, theories suggest that it may have a tipping point beyond which recovery is difficult, hence ...

Stress and Heart Rate Variability: A Meta-Analysis and Review of the Literature
Psychiatry Investigation, 2018 Objective Physical or mental imbalance caused by harmful stimuli can induce stress to maintain homeostasis. During chronic stress, the sympathetic nervous system is hyperactivated, causing physical, psychological, and behavioral abnormalities. At present,

Identification of a New HIV-1 BC Intersubtype Circulating Recombinant Form (CRF108_BC) in Spain
Viruses, 2021 The extraordinary genetic variability of human immunodeficiency virus type 1 (HIV-1) group M has led to the identification of 10 subtypes, 102 circulating recombinant forms (CRFs) and numerous unique recombinant forms.

Annular Modes in the Extratropical Circulation. Part I: Month-to-Month Variability*
, 2000 The leading modes of variability of the extratropical circulation in both hemispheres are characterized by deep, zonally symmetric or ‘‘annular’’ structures, with geopotential height perturbations of opposing signs in the polar cap region and in the ...

Step width variability as a discriminator of age-related gait changes
Journal of NeuroEngineering and Rehabilitation, 2020 Background There is scientific evidence that older adults aged 65 and over walk with increased step width variability which has been associated with risk of falling. However, there are presently no threshold levels that define the optimal reference range

A Complete Proof of an Important Theorem for Variable-to-Variable Length Codes [PDF]
arXiv, 2023 Variable-to-variable length (VV) codes are a class of lossless source coding. As their name implies, VV codes encode a variable-length sequence of source symbols into a variable-length codeword. This paper will give a complete proof of an important theorem for variable-to-variable length codes.

, 2002 Aerosol radiative forcing is a critical, though variable and uncertain, component of the global climate. Yet climate models rely on sparse information of the aerosol optical properties.

ENSO-like interdecadal variability: 1900–93
Oceanographic Literature Review, 1997 A number of recent studies have reported an ENSO-like EOF mode in the global sea surface temperature (SST) field, whose time variability is marked by an abrupt change toward a warmer tropical eastern Pacific and a colder extratropical central North ...
