Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

The article delves into the intricate relations of entanglement in multipartite quantum systems, focusing on the monogamy and polygamy inequalities that govern these interactions. It introduces a unified framework for various entanglement measures, including the unified-(q, s) entanglement, Rényi-q entropy, Tsallis-q entropy, and entanglement of formation. By presenting tighter and more general monogamy and polygamy inequalities, the research offers valuable insights and advancements in the field of quantum information processing. The study not only unifies existing measures but also provides new perspectives on the distribution and constraints of entanglement in quantum systems, making it a significant contribution to the understanding of quantum correlations.
