Spatially variant apodization (SVA) is reformulated for use on synthetic aperture radar imagery with an arbitrary sampling rate. The algorithm is implemented as a spatially varying three-point finite impulse response filter, and constraints on the filter parameters are developed from physically motivated concepts. By varying the parameters of the filter,(More)
Steps to Respect: A Bullying Prevention Program (STR) relies on a social–ecological model of prevention to increase school staff awareness and responsiveness, foster socially responsible beliefs among students, and teach social–emotional skills to students to reduce bullying behavior. As part of a school-randomized controlled trial of STR, we examined(More)
We discuss the effects of QCD corrections to the on-shell decay t → bW . We resolve the scale ambiguity using the Brodsky-Lepage-Mackenzie scheme, and find that the appropriate coupling constant is α s (0.122mt). The largest long distance contribution comes from the definition of the on-shell mass of the top quark. We note that QCD corrections to the(More)
Hemolymph osmolarity has great effect on honey bee health, especially in arid and semi-arid zones. It regulates water and nutrients in stressed tissues. Osmotic concentration in three races (Apis mellifera ligustica, A. m. carnica and A. m. jemenitica) of Apis mellifera was tested in central Saudi Arabia during spring and summer seasons in 2015. Newly(More)
Delicate cancellations among diagrams can result in the vanishing of threshold amplitudes in the standard model. This phenomenon is investigated for multi-Higgs production by scalar, vector, and fermionic fields. A surprising gap is found where although the tree-level amplitude for 2 incoming gauge bosons to produce Nv particle may vanish, the amplitude for(More)

We calculate the O(αsβ0) corrections to the decay rate b → cc̄s. For reasonable values of mc/mb this term is of the same order as both the one-loop and O(αs log mW/mb) corrections to the decay rate. For mc/mb = 0.3 the O(αsβ0) corrections enhance the rate by ∼ 18% . We also discuss the O(αsβ0) corrections to Rτ , the B semileptonic branching fraction and(More)
