It is known that a quantum bit commitment that would be secure against all attacks allowed by quantum mechanics is impossible if a standard model of communication is used. This result was a severe step back for quantum cryptography. However, this impossibility result applies only if no bit commitment exists initially between Alice and Bob. Here we consider an initial situation in which the comm...

Frederick R.M. Barnes Computing Laboratory, University of Kent, Canterbury, KENT. CT2 7NF ([email protected]) Abstract. This paper describes tranx86, a program which converts Extended Transputer Code (ETC) from a modified Inmos occam compiler, into IA32 code for execution on the Intel i386 family of processors within the KRoC/Linux system. Several optimisations are employed in an attempt to maxim...

The hydrolysis of ATP by acto-HMM has been studied during the transient state using a rapid-mixing apparatus. The rate of substrate binding was slightly slower and the rate of hydrolysis of the first molecule of ATP was essentially the same as for heavy meromyosin (HMM) alone. The rate of acto-HMM dissociation after binding substrate was too fast to measure in a stopped-flow apparatus, conseque...

Abstract The Roman vicus of Eisenberg in Rhineland-Palatinate (Germany) has always been considered to be an important iron smelting centre due numerous slag finds and relicts furnaces. Most excavations that revealed working debris have performed the nineteenth or early twentieth century. Their results interpretations doubtful, but more recent brought light further relics processes, which not, h...
