Due to the worldwide connectivity provided by the Internet, organizations are able to participate in dynamic networked value constellations; networks in which organizations jointly create value and satisfy customer needs. Participating in a networked value constellation does however increase the complexity of an organization’s environment, making correct and deep understanding of the organizati...

In order to find the susceptibility of the Claisen rearrangement and next proton shift reaction of ally) aryl etherto the substiment effects in pan position, the kinetic and the:rmodynamie parameters are calculated at The33 LTP level using 6-3110. b asis set. The calculated activation energies for the rearrangements and protonshift reactions are around 3133 kcaUmol and 52.16 kcal/mol, nap.. liv...

In the weak measurement formalism of Y. Aharonov et al. the so-called weak value Aw of any observable A is generally a complex number. We derive a physical interpretation of its value in terms of the shift in the measurement pointer’s mean position and mean momentum. In particular we show that the mean position shift contains a term jointly proportional to the imaginary part of the weak value a...

BACKGROUND Intraoperative intraocular pressure (IOP) in the prone position and IOP changes over time have not been evaluated in pediatric surgical patients. We sought to determine time-dependent changes in IOP in children undergoing surgery in prone position. METHODS Thirty patients undergoing neurosurgical procedures in prone position were included. Using a pulse-mode pneumatonometer, IOP wa...

A recent paper [Jokela et al., arxiv:0806.1491 (2008)] contains a surmise about an expectation value in a Coulomb gas which interacts with an additional charge ξ that sits at a fixed position. Here I demonstrate the validity of the surmised expression and extend it to a certain class of higher cumulants. The calculation is based on the analogy to statistical averages in the circular unitary ens...

objectives this study aimed to assess the effect of object position in the field of view (fov) of cbct on detection of vrfs in teeth with intra-canal posts. materials and methods the crowns of 60 extracted premolar teeth were cut at the level of cementoenamel junction (cej). root canals were filled with gutta-percha and filling of the coronal 2/3 of the root canals was subsequently removed to f...

We use asymptotic analysis to derive the optimal hedging strategy for an option portfolio hedged using an imperfectly correlated hedging asset with small transaction costs, both fixed per trade and proportional to the value traded. In special cases we opbtain explicit formulae. The hedging strategy involves holding a position in the hedging asset whose value lies between two bounds, which are i...

Information security is very important task in the field of information and communication technology. Encryption is one way to secure information. In this paper we present combined concept of pixel and position manipulation technique for image encryption. The proposed technique involves three stages. In first stage pixel position manipulation is done by using pixel shuffling block where index v...

Motivation: Many heuristic algorithms have been designed to approximate p-values of DNA motifs described by position weight matrices, for evaluating their statistical significance. They often significantly deviate from the true p-value by orders of magnitude. Exact p-value computation is needed for ranking the motifs. Furthermore, surprisingly, the complexity of the
