This study employs the Corpus of Contemporary American English (COCA) to investigate the extended unit of meaning of the verb witness, analyzing its collocational patterns, the semantic tendencies of its co-occurring words, and semantic prosody information embodied in the context. The findings reveal that the verb witness primarily collocates with nouns and adverbs, with noun collocations emphasizing event description and adverb collocations highlighting temporal experience. Additionally, witness forms diverse syntactic structures through various collocations with prepositions, auxiliary verbs, pronouns, determiners, nouns, and other word classes. In terms of semantic tendencies, witness conveys directness, firsthand experience, and is often associated with significant events. Its semantic prosody is predominantly neutral or negative, with fewer instances of positive connotations. This study provides new insights for understanding the lexical behavior of witness and a practical framework for language learning and teaching.展开更多

The Schmidt number is a quantity of the entanglement dimension of a bipartite state. Here we build families of k-positive maps from the symmetric information complete positive operator-valued measurements and mutually unbiased bases, and we also present the Schmidt number witnesses, correspondingly. At last, based on the witnesses obtained from mutually unbiased bases, we show the distance between a bipartite state and the set of states with a Schmidt number less than k.展开更多

However, for the particularity of children＇s cognitive ability,we should embody this particularity when we judge children＇s testimony and protect children witnesses.展开更多
