Aniong the known classes of nonlinear optical materials, z-conjugated polymers are very attractive because of their large, third-order optical susceptibilities and ultrafast response times.lP5 The large optical nonlinearity of conjugated polymers has long been recognized as arising from the z-electron delocalization along the polynler chains2 Recently, aromatic heterocyclic ladder-type polymers...

AIMS To evaluate the BBL Crystal MRSA ID System for detection of oxacillin resistance in Staphylococcus aureus. METHODS 52 methicillin resistant S aureus (MRSA) from five different countries and 85 methicillin susceptible S aureus (MSSA) were included. The species was confirmed by tube coagulation and detection of the clumping factor using the Staphaurex Plus. Clonal non-identity of the MRSA ...

[1] An idealized, two‐dimensional numerical modeling study is presented to investigate the effects of variable shelf slope and stratification on surface mixed layer (SML) nutrient supply during upwelling. As reported previously, the physical flow regime is governed by a topographic Burger number. Gradual shelf slope and weak stratification concentrate onshore transport in the bottom boundary la...

In contrast to classical chemical phenomenology, theory suggests that proteins may undergo downhill folding without an activation barrier under certain thermodynamic conditions. Recently, the BBL protein was proposed to fold by such a downhill scenario, but discrepancies between experimental results found in different groups argue against this. After briefly reviewing the major experimental stu...

The dissipation of the kinetic energy (KE) associated with oceanic flows is believed to occur primarily in bottom boundary layer (BBL), where drag converts KE from mean heat loss through irreversible mixing at molecular scales. Due practical difficulties direct observations on small-scale turbulence close seafloor, most up-to-date estimates rely a simple bulk formula (CdU3) proposed by G.I. Tay...

Cardiac arrest (CA) is the most common cause of death in hemodialysis patients, and factors that improve survival after arrest are unknown. This study sought to identify modifiable factors that are associated with survival after CA in hemodialysis clinics. Patients who experienced in-center CA in the Gambro Healthcare System in the United States from 2002 to 2005 were identified. Patient charac...

Studies on members of protein families with similar structures but divergent sequences provide insights into the effects of sequence composition on the mechanism of folding. Members of the peripheral subunit-binding domain (PSBD) family fold ultrafast and approach the smallest size for cooperatively folding proteins. Phi-Value analysis of the PSBDs E3BD and POB reveals folding via nucleation-co...

A data-driven model is used to analyse the global effects of biodiesel on energy–water–food (EWF) nexus, and understand complex environmental correlation. Several criteria measure sustainability four main limiting factors for production are discussed in this paper. The includes water stress, food feedstock quantity crude oil price. 155-country covers prices ranging from USD10/bbl USD160/bbl, re...
