A compact formulation of the set of tours neither in a graph nor its complement is presented and illustrates a general methodology proposed for constructing polyhedral models of decision problems based upon permutations, projection and lifting techniques. Directed Hamilton tours on n vertex graphs are interpreted as (n-1)- permutations. Sets of extrema of Birkhoff polyhedra are mapped to tours ...

Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields. 

Hydrophobic grade fumed silicas are generally used in tabletting as lubricants. They are also found to retard the release of pharmaceutical actives. This is because of their hydrophobic nature, which gives good cohesive and adhesive properties. considering this point it was thought that they could be used as dry coating agents for solid dosages forms. The model drug selected for this work was p...

Oenococcus oeni is part of the microbial terroir involved in wine production. Here, we present three genome sequences of O. oeni strains isolated from spontaneous malolactic fermentation of cultivar Cabernet Sauvignon Maipo Valley, Chile.

Glicocorticosteroides estão incluídos na lista de substâncias proibidas da Agência Mundial Antidoping como analitos que dispensam quantificação. Entretanto, abordagens semiquantitativas são necessárias antes de relatar um resultado analítico adverso para essa classe de substâncias. Cromatografia líquida acoplada à espectrometria de massa (LC-MS) tem sido empregada com excelente seletividade e e...

In a modern three-dimensional integrated circuit (3D IC), vertically stacked dies are interconnected using through silicon vias. 3D ICs are subject to undesirable temperature-cycling phenomena such as through silicon via protrusion as well as void formation and growth. These cycling effects that occur during early life result in opens, resistive opens, and stress induced carrier mobility reduct...

| Models of achievable routing, i.e., chip wireability, rely on estimates of available and required routing resources. Required routing resources are estimated from placement, or (a priori) using wire length estimation models. Available routing resources are estimated by calculating a nominal \supply," then taking into account such factors as the e ciency of the router and the impact of vias. M...
