in recent years multiple roles of wetland ecosystem and their values for human have increasingly been known, but their environmental and human life importance are usually considered to be less than their actual value. wetlands are one of the most important critical areas in the world. due to unique biodiversity and having high volume production, wetlands have special place from controlling role...

Escherichia coli expresses type-I fimbriae; these are protrusions from the outer cell wall and have been identified as a virulence factor. They are also expressed by commensal strains of E. coli although (at any one time) only by a small proportion of the population. The orthodox interpretation of this is that fimbriation is regulated so as (i) to trigger a host-based release of nutrients in th...

Current versions of nominalism in the philosophy of mathematics have the benefit of avoiding commitment to the existence of mathematical objects. But this comes with a cost: to avoid commitment to mathematical entities, nominalists cannot take mathematical theories literally, and so, they seem unable to accommodate mathematical practice. In a recent work, Jody Azzouni has challenged this conclu...

quasinormal subgroups have been studied for nearly 80 years. in finite groups, questions concerning them invariably reduce to p-groups, and here they have the added interest of being invariant under projectivities, unlike normal subgroups. however, it has been shown recently that certain groups, constructed by berger and gross in 1982, of an important universal nature with regard to the existen...

The space of ${\cal N}=4$ supersymmetric Yang-Mills theories exhibits an intricate structure global one-form symmetries and $SL(2,\mathbb{Z})$ duality orbits. In this paper we study from the point view holographic dual Type IIB string theory. Generalizing work by Witten, map different based on gauge algebras $su(N)$, $so(N)$, $sp(N)$ to a choice boundary conditions bulk fields. We show how thei...

k-nearest neighbour (kNN) collaborative filtering (CF), the widely successful algorithm supporting recommender systems, attempts to relieve the problem of information overload by generating predicted ratings for items users have not expressed their opinions about; to do so, each predicted rating is computed based on ratings given by like-minded individuals. Like-mindedness, or similarity-based ...
