The NAK team participated in the NTCIR-11 RITE-VAL task. This paper describes our textual entailment system and discusses the official results. Our system adopts statistical method: classification of the support vector machine (SVM). For Japanese SV subtask, our best result was 63.19 for macro-F1 score and 74.55 for accuracy. For Japanese FV subtask, our best result was 53.07 for macro-F1 score...

In the search for novel materials vacuum electron sources, multi-alkali antimonides and in particular sodium-potassium-antimonides have been recently regarded as especially promising due to their favorable electronic optical properties. framework of density-functional theory many-body perturbation theory, we investigate structure dielectric response two representative members this family, namel...

One of the main challenges using biofuels, such as pellets or wood chips in domestic boilers, is slagging and fouling risks associated to process, which could damage boiler limit its efficiency. The prediction sintering biomass combustion essential establish biofuel quality standards, minimize their harmful effects. In this work, we analysed chemical composition 40 woodchips samples from differ...

Reliable multicast in wireless applications is gaining importance with the development in technology. Applications like multicast file transfer, distributed computing, chat and whiteboard applications need reliability. However, due to mobility and wireless channel characteristics, obtaining reliability in data transfer is a difficult and challenging task. IEEE 802.11 does not support reliable m...

Many cancer patients fail to respond to chemotherapy because of the intrinsic resistance of their cancer to pro-apoptotic stimuli or the acquisition of the multidrug resistant phenotype during chronic treatment. Previous data from our groups and from others point to the sodium/potassium pump (the Na+/K+-ATPase, i.e., NaK) with its highly specific ligands (i.e., cardiotonic steroids) as a new ta...

OBJECTIVE To develop a simple, physiologically based mathematical model of pancreatic duct cell secretion using experimentally derived parameters that generates pancreatic fluid bicarbonate concentrations of >140 mM after CFTR activation. METHODS A new mathematical model was developed simulating a duct cell within a proximal pancreatic duct and included a sodium-2-bicarbonate cotransporter (N...

Using the techniques of X-ray diffraction, polarizing microscopy, uniaxial compression, and scanning electron microscopy (SEM), relationships between microfracture features mineral morphology granite were studied. The results showed that feldspar, quartz, biotite are main components samples in this study. Biotite has a self-shaped flake structure with perfect cleavage. K-feldspar lattice double...
