Knowing the fact that the main weakness of the most standard methods including k-means and hierarchical data clustering is their sensitivity to initialization and trapping to local minima, this paper proposes a modification of convex data clustering  in which there is no need to  be peculiar about how to select initial values. Due to properly converting the task of optimization to an equivalent...

Structural genomics initiatives provide ample structures of "hypothetical proteins" (i.e., proteins of unknown function) at an ever increasing rate. However, without function annotation, this structural goldmine is of little use to biologists who are interested in particular molecular systems. To this end, we used (an improved version of) the PatchFinder algorithm for the detection of functiona...

Relations between OWFs, PRGs and PRFs (revised) Jan-Erik Ekberg February 19, 2002 1 Introdu tion These le ture notes intend to give an overview of the provable relations between one-way fun tions (OWFs), pseudorandom generators (PRGs) and pseudorandom fun tions (PRFs). Only a sele ted number of proofs and redu tions are thoroughly presented in this paper (most are left to the referen es), but t...

A simple and effective method for the preparation of platinum nanoparticles (Pt NPs) grown on amino-func‐ tionalized halloysite nanotubes (HNTs) was developed. The nanostructures were synthesized through the func‐ tionalization of the HNTs, followed by an in situ approach to generate Pt NPs with diameter of approximately 1.5 nm within the entire HNTs. The synthesis process, composition and morp...

Adapta on is a ubiquitous mechanism by which sensory cells and neurons match their response proper es to the currently prevailing features of their input s muli. Visual mo on-sensi ve neurons in the fl y brain have been used as a valuable model system for the in vivo analysis of physiological mechanisms underlying neuronal adapta on. In this model system the func onal signifi cance of adapta on...

We describe a rigorous ATPG-like methodology for validating the branch prediction mechanism of the Pow-erPC604 which can be easily generalized and made applicable to other processors. Test sequences based on nite state machine (FSM) testing are derived from small FSM-like models of the branch prediction mechanism. These sequences are translated into PowerPC instruction sequences. Simulation res...

This article gives a short and elementary presentation of random evolutions toward applications in reliability and quality engineering. At first, the following two examples are presented: dynamical stochastic systems and increment processes both in Markov media. A dynamical system in continuous time is presented since nowadays they are widely used in dynamic reliability modeling. Limit theorems...

In this paper, a Krein-Milman  type theorem in $T_0$ semitopological cone is proved,  in general. In fact, it is shown that in any locally convex $T_0$ semitopological cone, every convex compact saturated subset is the compact saturated convex hull of its extreme points, which improves the results of Larrecq.
