Using 7-hydroxy-1-indanone as a prototype (I), which exhibits excited-state intramolecular proton transfer (ESIPT), chemical modification has been performed at C(2)-C(3) positions by fusing benzene (molecule II) and naphthalene rings, (molecule III). I undergoes an ultrafast rate of ESIPT, resulting in a unique tautomer emission (λ(max) ∼530 nm), whereas(More)
OBJECTIVE Since virus infections in AIDS patients are mostly inevitable and as they frequently cause disease deterioration and therapeutic failures, a comprehensive investigation was made of the influence of the coinfections of 9 well-known viruses on disease progression in patients infected with human immunodeficiency virus type 1 (HIV). METHODS A(More)

We argue that the usual order flow model needs to be recast in broader terms to incorporate the transaction costs of liquidity and the(More)
The title compound, C(17)H(12)N(2), comprises a norbornane unit having a dicyanona-phthalene ring fused on one side. Both cyano groups are twisted slightly out of the plane of the naphthalene ring system [C-C-C-C torsion angle = 1.9 (2)°]. In the crystal, inversion-related mol-ecules are linked by pairs of weak C-H⋯N hydrogen bonds, forming dimers.
The URA is one of the coded aperture imaging techniques. It has been used or proposed for X-ray imaging. In the URA, the pinhole is replaced by multi-pinholes array arranged in m-sequences. The pattern of the array is set as its correlation between the multi-pinholes and the decoding operator must be the delta function. So the URA can provide a(More)
High performance thin-film transistors were fabricated using a new precursor of pentacene through a multiple spin-heat procedure. High quality pentacene thin films can be prepared by this method and hence a FET device can be made in a top-contact configuration. The device exhibited a remarkable field-effect mobility of 0.38 cm(2) V(-1) s(-1) with an on/off(More)
