We complete the Wilf classification of signed patterns of length 5 for both signed permutations and signed involutions. New general equivalences of patterns are given which prove Jaggard’s conjectures concerning involutions in the symmetric group avoiding certain patterns of length 5 and 6. In this way, we also complete the Wilf classification of S5, S6, and S7 for both permutations and involut...

This Technical Bulletin reviews the indications for gonadotropin treatment in anovulatory women; outlines the recommended pretreatment evaluation, treatment regimens, and monitoring; describes the alternatives and adjuncts to treatment with gonadotropins; and summarizes the complications of gonadotropin treatment. (Fertil Steril 2008;90:S7–12. 2008 by American Society for Reproductive Medicine.)

BACKGROUND & OBJECTIVE Activation of T cells is mediated through two critical signals provided by activated macrophages. The first signal is triggered when T cell receptor (TCR) binds to the major histocompatibility antigen (MHC/Ag) complex. The second signal is the interaction of co-stimulatory molecules with their respective ligands on T cells for their activation and proliferation. We undert...

The photoluminescence properties of (Gd,Yb,Tb)PO4 nanocrystals synthesized via a hydrothermal route at 150 °C are reported. Energy-transfer from Gd(3+) to Tb(3+) is witnessed by the detailed analyses of excited-state lifetimes, emission quantum yields, and emission and excitation spectra at room temperature, for Tb(3+) concentrations ranging from 0.5 to 5.0 mol%. Absolute-emission quantum yield...

High pressure and high temperature (HPHT) conditions in geothermal wells have necessitated the need to develop thermally stable drilling mud systems combat potential complications. This is because fluids degrade under HPHT due effects. study therefore aims establish optimum concentration of a cationic surfactant that would successfully modify surface silica nanoparticles thereafter, evaluate pe...

The complete sequence of the isolate Mw10 of Rice yellow mottle virus was determined. Sequence comparisons revealed 8.4% to 10.7% nucleotide divergence from the published sequences, resulting in the definition of the strain S7. Importantly, a putative recombination event was identified encompassing the viral genome-linked protein involved in host adaptation.
