The LassoProt server, http://lassoprot.cent.uw.edu.pl/, enables analysis of biopolymers with entangled configurations called lassos. The server offers various ways of visualizing lasso configurations, as well as their time trajectories, with all the results and plots downloadable. Broad spectrum of applications makes LassoProt a useful tool for biologists, biophysicists, chemists, polymer physi...

Most of the time, we have the raw data to conduct the necessary statistical analysis in SAS®. However, when there is only summary data available, some additional SAS coding is necessary in order to perform the hypothesis test. SAS procedures, as well as simplified macros (%SUM_TTEST, %SUM_ANOVA, %P_ANOVA, %SUM_CHI) with examples, will be discussed in this paper for chi-square test, two sample t...

Since 1990 the European xed station geodetic Very Long Baseline Interferometry (VLBI) network has been observing on a regular basis in order to determine crustal motion in Europe. Usually the analyses of geodetic VLBI data are set up in two diierent ways: a) to produce station coordinates for each observation epoch from independent parameter adjustments and b) to compute station coordinates at ...

This paper describes system analyze of the Windkessel models. The equations, space state and transfer functions of 2, 3 and 4 elements Windkessel models are described. The Simulink environment model schemas are presented as well. The Bode frequency and step response analyses are presented for all three models as well. Moreover the simulation of the special input signal which represents blood fl...

CYBER attacks have risen in recent times. The attack on Sony Pictures by hackers, allegedly from North Korea, has caught worldwide attention. The President of the United States of America issued a statement and “vowed a US response after North Korea’s alleged cyber-attack”.This dangerous malware termed “wiper” could overwrite data and stop important execution processes. An analysis by the FBI s...

Every single company or institution wants to utilize its resources in the most efficient way. In order to do so they have to be have good structure. The new way to analyze company structure by utilizing existing within company natural social network and example of its usage on Enron company are presented in this paper.

Card sorts are a knowledge elicitation technique in which participants are given a collection of items and are asked to partition them into groups based on their own criteria. Information about the participant’s knowledge structure is inferred from the groups formed and the names used to describe the groups through various methods ranging from simple quantitative statistical measures (e.g. co-o...

Designers of massively parallel cluster computers help to ensure system reliability by using sensors to monitor a cluster’s component systems. Current PCs ship with built-in data acquisition devices that monitor system parameters such as voltage, temperature, and hard drive status, in order to anticipate possible system failure. One modality for PC monitoring which is currently ignored is sound...

In biology proteins play a central role. They are the most important “building parts” of living organisms having important functions (enzymes, structure, regulation, signalling, defence). Molecular biology teaches us that proteins are built in a process called gene expression or protein expression. The information is stored in genes on the DNA, located in the cell nucleus. Since proteins are sy...
