Estimation of plant dry matter to management of rangelands fast as well as high accuracy is important for managers. Research aims to compare Plant Dry Matter Productivity (PDMP) values estimated by Normalized Difference Vegetation Index (NDVI) derived from satellite images BKA, KVA according to different levels of satellite image processing, for AL-Sweeda Badia (Syria), during the April, July o...

Age-hardenable aluminum alloys used in aerospace structures are susceptible to environment assisted fatigue crack propagation (EFCP), limiting component durability and safety. The objective is to quantitatively understand EFCP and its inhibition for important aerospace alloys: 7075-T651 (Al-Zn-Cu-Mg), C433-T3 (Al-Cu-Mg), and C47A-T86 (AlCu-Li). EFCP is understood through the hydrogen embrittlem...

Why Is the Mouse Such a Poor Model for DN? Over the years, a number of mouse models of diabetes have been developed and studied. Although in-depth investigation of renal function and pathology has been somewhat limited, no mouse model to date exhibits the classic pathologic lesions of DN that are observed in humans: Glomerular nodulosclerosis, Kimmelstiel-Wilson nodules, fibrin drop lesions, or...

D-branes can end on orbifold planes if the action of the orbifold group includes (−1)FL . We consider configurations of D-branes ending on such orbifolds and study the low-energy theory on their worldvolume. We apply our results to gauge theories with eight supercharges in three and four dimensions. We explain how mirror symmetry for N = 4 d = 3 gauge theories with gauge group Sp(k) and matter ...

We present a new locality sensitive hashing (LSH) algorithm for c-approximate nearest neighbor search in lp with 1 < p < 2. For a database of n points in lp, we achieve O(dn ) query time and O(dn + n) space, where ρ ≤ O((ln c)/c). This improves upon the previous best upper bound ρ ≤ 1/c by Datar et al. (SOCG 2004), and is close to the lower bound ρ ≥ 1/c by O’Donnell, Wu and Zhou (ITCS 2011). T...

background: transforming growth factor-beta 1(tgf-β1) t869c (rs1800470, the same below) gene polymorphism is notably relative with the development of diabetic nephropathy (dn)，and cc/ct genotype diabetic have higher frequency of than tt genotype diabetic. to find out individual risk factors in the two genotypes especially in susceptible genotype could provide more efficient and targeted prevent...

We present a new locality sensitive hashing (LSH) algorithm for c-approximate nearest neighbor search in `p with 1 < p < 2. For a database of n points in `p, we achieve O(dn) query time and O(dn + n1+ρ) space, where ρ ≤ O((ln c)2/cp). This improves upon the previous best upper bound ρ ≤ 1/c by Datar et al. (SOCG 2004), and is close to the lower bound ρ ≥ 1/c by O’Donnell, Wu and Zhou (ITCS 2011...

Rates of denitrification and nitrous oxide (N2O) formation, and the sources of N2 and N2O, were examined by the isotope-pairing technique in three U.K. estuaries (Colne, Humber, Conwy), which ranged from extremely nutrified to oligotrophic. Nitrous oxide concentrations were supersaturated throughout the year with annual averages of 603% in the Colne, 158% in the Humber, and 133% in the Conwy, i...

Parkinson's disease (PD) pathology is characterized by the degeneration of midbrain dopamine neurons (DNs) ultimately leading to a progressive movement disorder in patients. The etiology of DN loss in sporadic PD is unknown, although it is hypothesized that aberrant protein aggregation and cellular oxidative stress may promote DN degeneration. Homozygous mutations in DJ-1 were recently describe...
