The Minimal Supersymmetric Standard Model (MSSM) contains two Higgs doublets Hu and Hd coupling to upand down-type quark fields, respectively. The neutral components of these Higgs doublets acquire vacuum expectation values (vevs) vu and vd with the sum v 2 u+v 2 d being fixed to v ≈ (174 GeV) and the ratio tan β ≡ vu/vd remaining as a free parameter. Large values of tanβ (∼ 50) are theoretical...

Uncoated surfaces of high index glasses when cemented to form lens doublets have inferior antireflection properties to doublets of low index glass. This can be overcome by the application of a single layer coating of aluminum oxide prior to cementing.

BACKGROUND Evidence strongly suggests that spontaneous doublet mutations in normal mouse tissues generally arise from chronocoordinate events. These chronocoordinate mutations sometimes reflect "mutation showers", which are multiple chronocoordinate mutations spanning many kilobases. However, little is known about mutagenesis of doublet and multiplet mutations (domuplets) in human cancer. Lung ...

The efficacy and toxicity of oxaliplatin-based versus carboplatin/cisplatin-based doublets in patients with previously untreated nonsmall cell lung cancer (NSCLC) have been compared.We searched published randomized controlled trials of oxaliplatin-based or carboplatin/cisplatin-based medications for NSCLC. A fixed effect model was used to analyze outcomes which were expressed as the hazard rati...
