The performance of block-matching sub-pixel motion estimation algorithms under the adverse conditions of image undersampling and additive noise is studied empirically. This study is motivated by the requirement for reliable subpixel accuracy motion estimates for motion compensated observation models used in multi-frame super-resolution image reconstruction. Idealized test functions which includ...

Metazoan genes are embedded in a rich milieu of regulatory information that often includes multiple enhancers possessing overlapping activities. In this study, we employ quantitative live imaging methods to assess the function of pairs of primary and shadow enhancers in the regulation of key patterning genes-knirps, hunchback, and snail-in developing Drosophila embryos. The knirps enhancers exh...

The mode of agronomic traits inheritance was investigated in safflower (Carthamus tinctorius L.) in drought stress as a new report. Five generation including P1, P2, F1, F2 and F3 that derived from the cross of IL.111 (drought sensitive) ×Mex.22-191 (drought tolerance) were used in a randomized complete block design with two replic...

Abstract The equivariant Heegaard genus of a 3-manifold W with the action finite group G diffeomorphisms is smallest an splitting for . Although reducible manifold and although if reducible, there essential sphere, we show that may be super-additive, additive, or sub-additive under connected sum. Using thin position theory 3-dimensional orbifolds, establish sharp bounds on manifolds, similar to...

Abstract Data brokers share consumer data with rivals and, at the same time, compete them for selling. We propose a ‘co-opetition’ game of and characterize their optimal strategies. When are ‘sub-additive’ merged value net merging cost being lower than sum values individual datasets, more likely to sell jointly. ‘super-additive’, greater competition emerges often. Finally, sharing is when effic...

to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...
