Dieback in temperate forests is understudied, despite this biome predicted to be increasingly affected by more extreme climate events a warmer world. To evaluate the potential drivers of dieback we reconstructed changes radial growth and intrinsic water-use efficiency (iWUE) from stable isotopes tree rings. Particularly, compared size, radial-growth trends, responses (temperature, precipitation...

OBJECTIVES Large socioeconomic differences exist in disease and mortality. This paper describes the distribution of specific medical reasons for sickness absence by grade of employment in the Whitehall II study and validates the medical reason by comparison with general practitioners' records. METHODS Analysis of sickness absence data on 5620 male and female civil servants aged 35-55 years. D...

BACKGROUND Mental disorders are common diagnostic causes for longer sickness absence and disability retirement in OECD-countries. Short sickness absence spells are also common, and neither trivial for health and work ability. We studied how prior short sickness absence spells and days are associated with subsequent longer sickness absence due to mental disorders in two age-groups of municipal e...

Neonatal spells are cardiorespiratory events that occur frequently in premature infants. Currently manual, nonspecific and ad-hoc identification of neonatal spells are documented by bedside clinical staff. A library of real-time streaming algorithms was developed to create real-time temporal analysis of high frequency data streams. In this paper we describe novel tri-event visualization for the...

The number of persons without health insurance is increasing. Although research has focused on the uninsured poor and the duration of spells without health insurance, less attention has been paid to the dynamics of spells without health insurance among those in poverty. Here it is shown that the typical uninsured spell is longer for the uninsured poor (roughly 8.3 months) than for the uninsured...

Abstract What elements should a parsimonious model reproduce at single scale to precisely simulate rainfall many scales? We posit these are: (a) the probability of dry and linear correlation structure wet/dry sequence as proxy reproducing distribution spells, (b) marginal nonzero its structure. build two‐state model, CoSMoS‐2s, that explicitly reproduces is easily applicable any timescale. Addi...

The direct sampling technique, belonging to the family of multiple-point statistics, is proposed as a nonparametric alternative to the classical autoregressive and Markovchain-based models for daily rainfall time-series simulation. The algorithm makes use of the patterns contained inside the training image (the past rainfall record) to reproduce the complexity of the signal without inferring it...

Abstract We provide an assessment of future daily characteristics African precipitation by explicitly comparing the results large ensembles global (CMIP5, CMIP6) and regional (CORDEX, CORE) climate models, specifically highlighting similarities inconsistencies between them. Results for seasonal mean are not always consistent amongst ensembles: in particular, models tend to project a wetter comp...

In the Asia/Pacific region there is evidence of prominent increases in the intensity and/or frequency of many extreme events such as heat waves, tropical cyclones, prolonged dry spells, intense rainfall, tornadoes, snow avalanches, thunderstorms, and severe dust storms in the region. Furthermore, the region is highly subject to natural hazards, such as the 2004 Indian Ocean Tsunami, the 2005 Pa...
