The structure and shape of the polypeptide chain of proteins are determined by the hybridized states of atomic orbitals in the molecular chain. The calculated s ratio in the sp hybrid orbitals is computed from the fractal dimension D of 81 proteins. The tertiary structures of 8 proteins covering 4 structural classes are analyzed. The proteins in the β-structural class are distinguished quantita...

Novel machine learning techniques for anomaly intrusion detection" (2004). ABSTRACT This paper explores the methodology of using kernels and Support Vector Machine (SVM) for intrusion detection. A new insight into two well known anomaly detection algorithms-STIDE and Markov Chain anomaly detectors, is achieved using kernel theory. We introduce two new classes of kernels used for intrusion detec...

accurate protein function prediction is an important subject in bioinformatics, especially wheresequentially and structurally similar proteins have different functions. malate dehydrogenaseand l-lactate dehydrogenase are two evolutionary related enzymes, which exist in a widevariety of organisms. these enzymes are sequentially and structurally similar and sharecommon active site residues, spati...

To evaluate distant effects of hand-arm vibration we studied Finnish forestry workers using chain saw during the years 1972 through 1990. The hearing was tested annually and individual regression curves for sensorineural hearing loss (SHL) were calculated. Robinson's model was used in prediction of SHL. The heart rate variation (HRV) indexes at rest and during deep breathing test were analyzed ...

Nacrtak Similarly to many other countries, the use of biologically degradable oils in forestry is also addressed by the Czech law. Several studies point out several technical problems regarding such regulations. It has not been demonstrated so far whether for example biologically degradable engine oils used for chain saw lubrication from mixture may be the cause of an excessive engine wear or d...

During a seminar several years ago, a participant asked if I could offer a tool that would help him manage physician relations at his hospital. Seeing this question as an opportunity for a class dialogue, I asked participants, “What is the first image that comes to mind when you hear the word ‘tool’?” The majority replied “hammer.” A few shouted, “gun” or “machine gun.” One even bellowed “chain...

Objective: Reconstruction of skin and soft tissue defects in the fingers is a huge challenge in recent years. We present a retrospective analysis of nine patients with arterialized venous flaps used to cover defects in the fingers. Methods: Nine patients with various finger tissue defects were treated using arterial venous flap from the hand. Seven patients were men and two were women with the ...

We have investigated conformational properties of a linear semiflexible homopolymer chain in the bulk and adsorption desorption behaviour in the presence of an attractive impenetrable curved surface using lattice models. Since, it is understood that the essential physics associated with the conformational behavior of such polymer chains can be derived from a model of a self avoiding walk (SAW) ...
