In this work, control strategies for combining two potentially powerful buffer management techniques in object bases were devised and evaluated: (1) buffer pool segmentation with segment-specific replacement criteria, and (2) dual buffering consisting of copying objects from pages into object buffers. Two diiensions exist for exerting control on the buffer pool: (1) the copying time which deter...
In this work, control strategies for combining two potentially powerful buuer management techniques in object bases were devised and evaluated: (1) buuer pool segmentation with segment-speciic replacement criteria, and (2) dual buuering consisting of copying objects from pages into object buuers. Two dimensions exist for exerting control on the buuer pool: (1) the copying time which determines ...
We define involutively self-dual matroids and prove a relationship between the bases and selfdual bases of these matroids. We use this relationship to prove an enumeration formula for the higher dimensional spanning trees in a class of cell complexes. This gives a new proof of Tutte’s theorem that the number of spanning trees of a central reflex is a perfect square and solves a problem posed by...
Opisthorchis viverrini is an important helminth pathogen of humans that is endemic in Thailand and Laos. Adult flukes reside within host bile ducts and feed on epithelial tissue and blood cells. Chronic opisthorchiasis is associated with severe hepatobiliary diseases such as cholangiocarcinoma. Here we report that adult O. viverrini secrete two major cysteine proteases: cathepsin F (Ov-CF-1) an...
We study the maximal multiplicity locus of a variety X over field characteristic p>0 that is provided with finite surjective radicial morphism δ:X→V, where V regular, for example, when X⊂An+1 hypersurface defined by an equation form Tq−f(x1,…,xn)=0 and δ projection onto V:=Spec(k[x1,…,xn]). The along points bounded degree, say d, extension K(V)⊂K(X). denote Fd(X)⊂X set d. Our guiding line searc...
Development of catalysts with highly efficient catalytic performance has a significant status in accelerating the MgH2 hydrogen storage system. In this work, we report Na2Ti3O7 catalyst rich oxygen vacancies (Na2Ti3O7-Ov), which was synthesized from Ti3C2-MXene, and confirm remarkable enhancement to MgH2. Expressly, initial dehydrogenation temperature + 5Na2Ti3O7-Ov (an addition 5 wt % Na2Ti3O7...
Using new properties of dual functions, we show that the method of constructing the dual bases recently presented in [P. Woźny, J. Comput. Appl. Math. 245 (2013), 75–85] can be significantly simplified. Next, we propose a simple algorithm of constructing the dual B-spline functions, which can be useful in solving some approximation problems related to numerical analysis or computer graphics.
BACKGROUND Many strategies to control opisthorchiasis have been employed in Thailand, but not in the other neighbouring countries. Specific control methods include mass drug administration (MDA) and health education to reduce raw fish consumption. These control efforts have greatly shifted the epidemiology of Opisthorchis viverrini (OV) infection over the last decade from presenting as densely ...
