2014 We report experimental measurements on the structure of invasion fronts obtained by slow vertical injection of liquid, non wetting, Wood metal into non consolidated crushed glass. The geometry of plane cuts of the invasion front both parallel and perpendicular to the flow direction is analysed. The structure of perpendicular cuts is self similar in a length scale range of 1 to 20 with a fr...

In this work, the empirical parameterization describing the alpha particles’ track depth in CR-39 detectors is extended to describe longitudinal track profiles against etching time for protons and alpha particles. MATLAB based software is developed for this purpose. The software calculates and plots the depth, diameter, range, residual range, saturation time, and etch rate versus etching time. ...

Vegetable-oil-based biolubricants are an excellent alternative to conventional lubricants. Instead of focusing on novel feedstocks, these should be further elucidated based their fatty acid composition, which influences tribological properties. Therefore, the study utilises gene expression programming (GEP) derive a boundary lubricity model for vegetable-oil-derived trimethylolpropane (TMP) est...

The saturation calculation in complex reservoirs remains a major challenge to the oil and gas industry. In simple formations, tendency towards models such as Archie or Simandoux for clean shaly respectively is always preferable. These were found be working effectively homogeneous formations within which porosity permeability are linked light of facies scheme. Where rocks show some degrees heter...

Saturation-recovery (SR) EPR at W-band (94 GHz) to obtain profiles of the membrane fluidity and profiles of the oxygen transport parameter is demonstrated for lens lipid membranes using phosphatidylcholine (n-PC), stearic acid (n-SASL), and cholesterol analog (ASL and CSL) spin labels, and compared with results obtained in parallel experiments at X-band (9.4 GHz). Membranes were derived from th...

A strategy is presented that allows a causal analysis of co-expressed genes, which may be subject to common regulatory influences. A state-of-the-art promoter analysis for potential transcription factor (TF) binding sites in combination with a knowledge-based analysis of the upstream pathway that control the activity of these TFs is shown to lead to hypothetical master regulators. This strategy...

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 ...
