Introduction: This study investigates basic dosimetric properties of unflattened 6 MV photon beam shaped by multileaf collimator and compares them with those of flattened beams.Materials and Methods: Monte Carlo simulation model using BEAM code was developed for a 6MV photon beam based on Varian Clinic 600 unique performance linac operated with and without a flattening filter in beam line. Dosi...

The SHAAD model (Adaptable, Adaptive and Dynamic Hypermedia System) allows adapting the web content delivered to the user based on his/her preferences and characteristics, and the features and limitations of the device used to interact with the system. In this work we use CC/PP (Composite Capabilities/Preference Profiles) to describe the characteristics of devices and users’ preferences. Finall...

Background: The prevalence of childhood obesity has risen dramatically in past several decades. Hormonal and genetic factor are rarely the cause of childhood obesity. Because obese children may suffer life long physical and emotional consequences, this imperative to discuss prevention with parents during well- child examinations. The obesity–related cardiovascular and lipid profiles are determi...

Research Theme 1. Quantification of trace amount of proteins (Etsuro Ito, Mika Morikawa, Mugiho Kaneda) We are developing the method to detect and quantify very tiny amount of a given protein in a small volume, such as in a single cell. We aim at establishing an enterprise to commercialize protein quantification reagents and kits based on this technique. Using our “enzyme cycling method”, it is...

[1] We present a novel explanation of the physical processes behind one type of cloud and ground-level tornadogenesis within a supercell. We point out that the charge separation naturally found in these large thunderstorms can potentially serve to contract the preexisting angular momentum through the additional process of the electric force. On the basis of this, we present a plausible geometry...

Homomorphic signatures (HS) allows the derivation of the signature of the message-function pair (m, g), where m = g(m1, . . . ,mK), given the signatures of each of the input messages mk signed under the same key. Multi-key HS (M-HS) introduced by Fiore et al. (ASIACRYPT’16) further enhances the utility by allowing evaluation of signatures under different keys. While the unforgeability of existi...

Recent developments in voting theory show that Condorcet profiles embedded in electorates are responsible for conflicts between pairwise voting methods and for reversals of rankings under positional methods whenever candidates are dropped or added. Because of the strong symmetry of the rankings of the candidates within these profiles, it can be argued that Condorcet profiles represent complete ...
