a r t i c l e i n f o Thin-films and organic field-effect transistors fabricated from a solution-processable precursor of zinc tetra-benzoporphyrin (ZnTBP) are reported. Amorphous, insulating precursor films were deposited by spin-casting and thermally converted into polycrystalline, semiconducting thin-films comprising grains on the order of 5 μm in diameter. Thin-film X-ray diffraction indica...

One approach to secure mobile agent execution is restricting the agent route to trusted environments. A necessary condition for this approach to be practical is that the agent route be protected. Previous proposals for agent route protection either offer low security or suffer from high computational costs due to cryptographic operations. We present two fast, hash-based mechanisms for agent rou...

We use the Percus-Yevick approach in the chemical-potential route to evaluate the equation of state of hard hyperspheres in five dimensions. The evaluation requires the derivation of an analytical expression for the contact value of the pair distribution function between particles of the bulk fluid and a solute particle with arbitrary size. The equation of state is compared with those obtained ...

OBJECTIVE The intraosseous (IO) route of vascular access has been increasingly used to administer resuscitative fluids and drugs to patients in whom reliable intravenous (IV) access could not be rapidly or easily obtained. It is unknown that to what extent the IO route has been used to gain vascular access during disasters and mass casualty events. The purpose of this review was to examine the ...

?-Aryl-?-diazoamides were synthesized in two steps under mild conditions. This expeditious route employs Pd-catalyzed C–H arylation of N-succinimidyl 2-diazoacetate to obtain 2-aryl-2-diazoacetates, followed by aminolysis. The ensuing diazo compounds can esterify carboxyl groups aqueous solution, and the ester products are substrates for an esterase. broad scope synthetic enables continued deve...

This paper discusses the vehicle routing problem with simultaneous pickup and delivery (VRPSPD), in which both pickup and delivery tasks simultaneously occur at various customer locations. The objective is to design a set of minimum distance routes with the minimum number of vehicles satisfying all the customers. This paper proposes a heuristic algorithm consisting of a route construction proce...
