Landsat image data have been used to document global land cover and land use change since 1972. The archive of Landsat imagery constitutes some of the most valuable climate data records available to the world. There has been a longstanding interest in not only maintaining the continuity of Landsat imaging, but in increasing its temporal repeat frequency to improve agricultural and ecological mo...

land use change may influence many natural phenomena and ecological processes, including runoff, soil erosion, sedimentation and soil conditions. decreasing of forest area in the north of iran is one of the critical problems in recent years. the aims of this study are to detect land use changes between 1967 to 2002 using satellite images of land sat 7 etm+ (2002), aerial photos and digital topo...

Let (k, s)-SAT refer the family of satisfiability problems restricted to CNF formulas with exactly k distinct literals per clause and at most s occurrences of each variable. Kratochv́ıl, Savický and Tuza [6] show that there exists a function f(k) such that for all s ≤ f(k), all (k, s)-SAT instances are satisfiable whereas for k ≥ 3 and s > f(k), (k, s)-SAT is NP-complete. We define a new functio...

Abstract Modeling studies have shown that surface air temperature (SAT) increase in response to an the atmospheric CO 2 concentration is larger over land than ocean. This so-called land–ocean warming contrast, φ , defined as land–mean SAT change divided by ocean-mean change, a striking feature of global warming. Small heat capacity unlikely sole cause because land-ocean contrast found equilibri...

Inflammatory cytokines released from adipose tissue play an important role in different pathological processes. In the present study, we investigated the inflammatory cytokine response of human subcutaneous adipose tissue (SAT) by applying the open-flow microperfusion technique. Four standard 18-gauge microperfusion catheters were inserted into periumbilical SAT of eight healthy male volunteers...

OBJECTIVE Lipodystrophy in HIV-1-infected antiretroviral-treated patients is often associated with opposite alterations in adipose tissue depots as follows: lipoatrophy of subcutaneous adipose tissue (SAT) versus lipohypertrophy of visceral adipose tissue (VAT). We determined the specific molecular alterations in VAT relative to SAT in patients. DESIGN We analyzed the expression of marker gen...

Understanding the variability of surface air temperature (SAT) over Tibetan Plateau (TP) and its precursory signals is great benefit to climate change adaptation socioeconomic development. This study explores summer SATs TP in oceanic land boundary conditions. The results show that eastern SAT significantly correlated with three precursors April: high-latitude North Atlantic sea (SST), northern...

Abstract Large ensemble simulations with six atmospheric general circulation models involved are utilized to verify the interdecadal Pacific oscillation (IPO) impacts on trend of Eurasian winter surface air temperatures (SAT) during 1998–2013, a period characterized by prominent Eurasia cooling (EC). In our simulations, IPO brings over west-central in about quarter observed EC that area. The is...
