Dropsondes from the NOAA G-IV aircraft were used to examine the presence of low bulk Richardson numbers RB in tropical cyclones. At least one 400-m layer above z 5 7.5 km exhibited RB , 1 in 96% of the sondes andRB# 0.25 in 35%of the sondes. The latter represent almost certain turbulence. Sondes frommajor Hurricane Ivan (2004) were examined in detail. Turbulent layers fell into three broad grou...

Thin-film nanocrystalline zinc oxide electrodes were fabricated by electrochemical deposition of ZnO on FTO-coated glass slides. promoted CdO coating top in amounts corresponding to 0.8, 0.1, and 0.05 C cm−2 electric units. Modification a small amount CdO, cm−2, shifts the photoactivity composite photoanode into visible part solar spectrum. It is shown that ZnO/(0.05C)CdO/FTO electrode demonstr...

Hedgehog (Hh) signaling plays essential roles in various developmental processes, and its aberrant regulation results in genetic disorders or malignancies in various tissues. Hyperactivation of Hh signaling is associated with lung cancer development, and there have been extensive efforts to investigate how to control Hh signaling pathway and regulate cancer cell proliferation. In this study we ...

The Steubenville Comprehensive Air Monitoring Program is comprised of two complementary and inter-related programs which cannot stand independently. One project is funded through the Ohio Department of Development (ODOD) Coal Development Office (CDO) under Grant Agreement No. CDO/D-98-2. The other project is described in Unsolicited Proposal No. P9908026 “Characterization of the PM2.5, PM10, an...

Various surface structures and polarities of one-dimensional nanostructures offer additional control in synthesizing heterostructures suitable for optoelectronic and electronic applications. In this work, we report synthesis and characterization of ZnO-CdO nanorod-based heterostructures grown on a-plane sapphire. The heterojunction formed on the sidewall surface of the nanorod shows that wurtzi...

We consider a bottom-up Markovian copula model of portfolio credit risk where dependence among credit names mainly stems from the possibility of simultaneous defaults. Due to the Markovian copula nature of the model, calibration of marginals and dependence parameters can be performed separately using a two-steps procedure, much like in a standard static copula set-up. In addition, the model adm...

Objective(s): Nanomaterials are playing major roles in imaging by delivering large imaging payloads, yielding improved sensitivity. Nanoparticles have enabled significant advances in pre-clinical cancer research as drug delivery vectors. Inorganic nanoparticles such as CdO/GrO nanoparticles have novel optical properties that can be used to optimize the signal-to-background ratio. This paper rep...

In view of the fact that different factor Copula models are only applicable to practical problems in collateralized debt obligations (CDO) market and there is no semianalytical solution under nonhomogeneous assumptions CDO pricing model, we designed a general numerical algorithm which was based on framework single model randomized quasi-Monte Carlo (RQMC) simulation method. We took two as examp...

We consider a factor approach to the pricing of basket credit derivatives and synthetic CDO tranches. Our purpose is to deal in a convenient way with dependent defaults for a large number of names. We provide semi-explicit expressions of the stochastic intensities of default times and pricing formulae for basket default swaps and CDO tranches. Two cases are studied in detail: mean-variance mixt...

This study addresses the tracking control problem of underwater vehicles using a new robust observation-based scheme. The advantages integral sign error (RISE) control, as well saturation function and well-known super-twisting algorithm, have been exploited to design saturated RISE (S+RISE) However, proposed S+RISE method requires continuous state measurements. To resolve this issue, continuous...
