Droughts are the most frequent natural disaster in regions at margins of East Asian summer monsoon (EASM), which pose threats to agriculture, economy, and human lives. However, limitations only approximately 60 years meteorological observations hamper our understanding characteristics mechanisms local hydroclimate. Trees growing marginal region EASM usually sensitive moisture variations have pl...

The reliability of paleoclimatic inferences from lake-sediment records rests on the understanding of how various sediment indicators respond to environmental changes. Despite the recent proliferation of paleoclimatic records, only a limited number of studies have rigorously evaluated potential indicators by comparing lake-sediment records with instrumental weather data. We analyzed annually lam...

Since the pioneering efforts of Duwez and co-workers in 1965, when a solid amorphous phase palladium-silicon (a-PdSi) was obtained vicinity eutectic concentration, much work has been done. However, some points related to atomic structures remain be systematized. In this work, 8 Pd100-cSic alloys (c = 2.5, 5, 10, 13.34, 15, 17.5, 20, 22 at%) are generated by molecular dynamics ab initio simulati...

Drought is one of the most destructive natural disasters causing serious damages to human society, and studies have projected more severe and widespread droughts in the coming decades associated with the warming climate. Although several drought indices have been developed for drought monitoring, most of them were based on large scale environmental conditions rather than ecosystem transitional ...

Productivity of old-growth beech forests in the Mediterranean Basin was measured by average stem basal area increment (BAI) of dominant trees at two mountain sites in the Italian Apennines. Both forests could be ascribed to the old-growth stage, but they differed markedly with regard to elevation (1000 vs. 1725 m a.s.l.), soil parent material (volcanic vs. calcareous), mean tree age (less than ...

We characterized fire history and examined climate–fire relationships in dry ponderosa pine (Pinus ponderosa) forests in the Zuni Mountains of northwestern New Mexico. Our findings indicate that the historical wildfire regime for the study area was typified by high-frequency, low-severity surface fires. Climate–wildfire relationships were assessed using both Superposed Epoch Analysis (SEA) and ...

The Santa Fe municipal watershed provides up to 40% of the city’s water and is at high risk of a standreplacing fire that could threaten the water resource and cause severe ecological damage. Restoration and crown fire hazard reduction in the ponderosa pine (PP) forest is in progress, but the historic role of crown fire in the mixed-conifer/aspen (MC) and spruce-dominated forests is unknown but...

OBJECTIVES to briefly outline the development and validation of the Parkinson's Disease Questionnaire (PDQ-39) and then to provide evidence for the use of the measure as either a profile of health status scores or a single index figure. DESIGN the PDQ-39 was administered in two surveys: a postal survey of patients registered with local branches of the Parkinson's Disease Society of Great Brit...

We examined the relationship between satellite measurements of solar-induced chlorophyll fluorescence (SIF) and several meteorological drought indices, including the multi-time-scale standard precipitation index (SPI) and the Palmer drought severity index (PDSI), to evaluate the potential of using SIF to monitor and assess drought. We found significant positive relationships between SIF and dro...
