Let G = (V,E) be an undirected graph, λk the kth smallest eigenvalue of the normalized Laplacian matrix of G, and ρ(k) the smallest value of the maximal conductance over all k-way partitions S1, . . . , Sk of V . Peng et al. [4] gave the first rigorous analysis of k-clustering algorithms that use spectral embedding and k-means clustering algorithms to partition the vertices of a graph G into k ...

The treatment of hospital wastewater is very complex, so treating polluted human urine a significant challenge. Here, we tested novel MMO-Ti/RuO2IrO2 electrode to reduce the ecotoxicity risk urines contaminated with antibiotics. This was used as anode in electro-Fenton (EF) and photoelectro-Fenton (PhEF) processes. results were compared those obtained using boron-doped diamond (BDD) anode, well...

Backward stochastic differential equations (BSDEs) were introduced by Pardoux and Peng [6], and it was shown in various papers that stochastic differential equations (SDEs) of this type give a probabilistic representation for the solution (at least in the viscosity sense) of a large class of system of semi-linear parabolic partial differential equations (PDEs). A new class of BSDEs, called back...

Peng and Nisbett (1999) claimed that members of Asian cultures show a greater preference than Euro-Americans for proverbs expressing paradox (so-called dialectical proverbs; e.g., Too humble is half proud). The present research sought to replicate this claim with the same set of stimuli used in Peng and Nisbett's Experiment 2 and a new set of dialectical and nondialectical proverbs that were sc...

Most sinograms (i.e., Chinese characters) are phonograms (phonetic compounds). A phonogram is composed of a semantic radical and a phonetic radical, with the former usually implying the meaning of the phonogram, and the latter providing cues to its pronunciation. This study focused on the sub-lexical processing of semantic radicals which are themselves free standing sinograms. Two primed naming...

Material of the paederine genus Lathrobium Gravenhorst, 1802 from the Chinese provinces Heilongjiang, Ningxia, Qinghai, Henan, Anhui, Zhejiang, Jiangxi, Hunan, Chongqing, Guizhou, Yunnan and Guangdong was examined. Twenty-one species were identified, seventeen of which are described as new: L. liuae (Heilongjiang: Hongwei); L. ningxiaense sp. n. (Ningxia: Heshangpu); L. baiyunense sp. n. (Henan...
