Lower termites harbor diverse consortia of symbiotic gut flagellates. Despite numerous evidence for co-cladogenesis, the evolutionary history these associations remains unclear. Here, we present Retractinymphidae fam. nov., a monogeneric lineage Trichonymphida from Serritermitidae. Although Retractinympha glossotermitis gen. nov. sp. morphologically resembles members genus Pseudotrichonympha , ...

This is a survey on the usage of the module theoretic notion of a “retractable module" in the study of algebras with actions. We explain how classical results can be interpreted using module theory and end the paper with some open questions.

Complex Event Processing (CEP) deals with processing of continuously arriving events with the goal of identifying meaningful patterns (complex events). In existing stream database approaches, CEP is manly concerned by temporal relations between events. This paper advocates for a knowledge-rich CEP with Stream Reasoning capabilities. Secondly, we address the problem of revision in event processi...

Pseudolestes mirabilis Kirby (1900), the only member of its genus, endemic to Hainan, continues to provoke speculation on its phylogenetic position. Based on its unique adult characters the species was originally placed in its own subfamily by Kirby (1900), and then in subfamily Lestinae (now Lestidae) by Calvert (1902) and Tillyard and Fraser (1938–1940). Fraser (1957) established the family P...

This study investigated the wind pressure characteristics of an elliptical plan retractable dome roof. Wind tunnel experiments were performed on roofs with varying wall height-to-span ratios (0.1–0.5) and opening (0, 10, 30, 50 %), where ratio was defined as open area roof to total The resulting peak coefficients closed then compared those Japanese load code (AIJ-RLB (2015)) there are no curren...

Let be a commutative ring with 1 and left unitary . In this paper, the generalizations for notions of compressible module retractable are given. An is termed to semi-essentially if can embedded in every non-zero semi-essential submodules. module, submodule an Some their advantages characterizations examples We also study relation between these classes some other modules.
