A total of 15 species of Manota Williston, 1896 are recorded from Brunei, based on the investigations in 2013-2014. Thirteen species are recorded from Ulu Temburong National Park and three species from the Universiti Brunei Darussalam Campus in Tungku. Six species are described as new to science: Manota belalongensis sp. n., M. kaspraki sp. n., M. macrothrix sp. n., M. megachaeta sp. n. and M. ...
The classical nucleation theory for homogeneous nucleation is formulated as a theory for a density fluctuation in a supersaturated gas at a given temperature. But Molecular Dynamics simulations reveal that it is small cold clusters which initiates the nucleation. The temperature in the nucleating clusters fluctuate, but the mean temperature remains below the temperature in the supersaturated ga...
We comment on the recent observation of the decay mode D sJ (2860) → DK by the BABAR Collaboration [B. Aubert et al. (BABAR Collaboration), arXiv:0908.0806], and contest their peremptory conclusion that the data exclude a 0 assignment for the D sJ (2860). In particular, we argue that the observed branching fraction B(D sJ (2860) → DK)/B(D sJ (2860) → DK) = 1.1 ± 0.15 ± 0.19 supports the existen...

Based on the secant condition often satisfied by quasi-Newton methods, two new versions of the Hestenes-Stiefel (HS) nonlinear conjugate gradient method are proposed, which are descent methods even with inexact line searches. The search directions of the proposed methods have the form dk = −θk gk + β H S k dk−1, or dk = −gk + β H S k dk−1 + θk yk−1. When exact line searches are used, the propos...
CLARIN-DK is a platform with language resources constituting the Danish part of the European infrastructure CLARIN ERIC. Unlike some other language based infrastructures CLARIN-DK is not solely a repository for upload and storage of data, but also a platform of web services permitting the user to process data in various ways. This involves considerable complications in relation to workflow requ...

WE REPORT A CASE OF A PATIENT WHO DEVELOPED A CEREBRAL INFARCTION, WHICH WAS ASSESSED USING A NEW AND ADVANCED DIFFUSION TECHNIQUE: diffusional kurtosis (DK) imaging. The signal changes on DK images were different from those on apparent diffusion coefficient (ADC) maps, and they seem to be useful for the prediction of early-stage tissue infarction. Although diffusion-weighted imaging and its me...
