This paper describes our patent retrieval system participated in the NTCIR-5 Patent Retrieval Task, Document Retrieval Subtask. The main scope of our method is the appropriate query expansion to improve recall. We extracted query terms from the topic claim, and expanded query terms extracted from sentences explained in the patent document including the topic claim. The explanation sentences wer...

We examine the converse of Church-Turing thesis and establish the existence of uncountable number of accelerated Turing machines. This leads to the case that these machines are unaffected by Gödel’s incompleteness

The photoelectron spectra of a number of characteristic hydrocarbon n systems are analyzed in terms of Koopmans' and non-Koopmans' contributions within a< limited configuration interaction · (CI) framework. The results for several compounds, including quinodimethanes, fulvenes, annulenes, and related systems, suggest frequent invalidity of the one-electron picture of ionization even in the oute...

The effective use of construction waste is great significance to the a sustainable society. This study investigated permeability recycled aggregate concrete with different qualities. aggregates were treated crystallizing agent. improvement effect crystallization was evaluated by rapid chloride ion migration test and electron microscope observation. results show that calcium silicate hydrate gen...

There are two kinds of estimates of the degree of approximation of continuous functions on [−1, 1] by algebraic polynomials, Nikolskii-type pointwise estimates and Jackson-type uniform estimates, involving either ordinary moduli of smoothness, or the DitzianTotik (DT) ones, or the recent estimates involving the weighted DTmoduli of smoothness. The purpose of this paper is to complete the table ...

From the perspective of innovation, current issue China’s tourism development is insufficient branding, which leads to homogeneity phenomenon goods and services. As intellectual property system stimulates creativity protects this article suggests that above-mentioned problem can be solved by effective strategy, namely creating distinctive identities through trademark protection use, raising qua...

BACKGROUND Prevalence rates of invalid baseline scores on computerized neurocognitive assessments for high school, collegiate, and professional athletes have been published in the literature. At present, there is limited research on the prevalence of invalid baseline scores in pre-high school athletes. HYPOTHESIS Pre-high school athletes assessed with baseline neurocognitive tests would show ...

Acrylate is a popular polymer grouting material that has been widely used to control groundwater seepage. However, the vulnerability of acrylate slurry dynamic water washout restricts its application in environments characterized by high flow velocity and pressures. In this paper, lithium bentonite (Li-B) was modify traditional magnesium (AC) material. The influence Li-B AC ratios on modified m...
