An enantioselective asymmetric reduction of phenyl ring-containing prochiral ketones toyield the corresponding optically active secondary alcohols was achieved with W110Asecondary alcohol dehydrogenase from Thermoanaerobacter ethanolicus (W110A TeSADH) inTris-HCl buffer using 2-propanol (30%, v/v) as cosolvent and cosubstrate. This concentration of2-propanol was crucial not only...

The recent advance in Field Programmable Gate Array (FPGA) technology hasbeen largely embraced by the communication industry, which views this technology asan effective and economical alternative to the design of Application Specific IntegratedCircuits (ASICs). The primary reasons for switching to FPGAs are lower developmentand non-recurring engineering costs, the flexibility to...

We have measured the spectral properties of five galaxies of low to intermediate Lx/Lb ratios with BeppoSAX and ASCA. A hard component (kT ∼ 4 − 10 keV) is observed in all galaxies. In NGC 1553 the BeppoSAX data show that this component is extended, and suggest an origin for the emission in the evolved stellar population. In NGC 3115, a point-like source appears embedded in an extended componen...

This thesis focuses on the wireless security in the physical layer with beamformingtechnique. As the wireless communications grow more important, a higher level ofsecurity is more demanding as well. New techniques have been proposed in complementto the existing encryption-based methods in the communications protocols. One of theemerging areas is the security enhancement in the p...

The work presented in this document deals with the formal verification models of Systems-on-a-Chipat the transaction level (TLM). We present the transaction level and its variants, and remind how this newlevel of abstraction is today necessary in addition to the register transfer level (RTL) to accommodate thegrowing constraints of productivity and quality, and how it integrates...

Under the common theme of physical-layer aware optimization and design in stochasticwireless networks, this dissertation can be broadly organized into the following two parts:In Part I, based on optimal stopping theory, a framework for channel-aware distributedscheduling is developed for exploiting rich diversities at the physical-layer and mediumaccess control (MAC) layer; ...

‘e security of public-key cryptography relies mainly on the diculty to solvesome mathematical problems, among which the discrete logarithm problem on€nite €eldsFpn . In this thesis, we study the variants of the number €eld sieve(NFS) algorithm, which solve the most eciently this problem, in the case wherethe characteristic of the €eld is medium.‘e NFS algorithm can be ...

The pH of pre-enrichment media containing feed/ingredients can become acidic during incubation due to bacterial utilization feed carbohydrates. This decrease in result cell injury or death, negatively impacting the detection Salmonella. Our objective was evaluate a new triple buffered peptone (TBP) against water (BPW) and lactose broth (LB) for recovery Salmonella from feed. Liquid cultures nal...
