We consider an arbitrary Abelian category $\mathcal {A}$ and a subcategory {T}$ closed under extensions direct summands, characterize those that are (semi-)special preenveloping in ; as byproduct, we generalize to this setting several classical results for categories of modules. For instance, get the special subcategories summands precisely which $({}^{\perp _{1}}\mathcal {T},\mathcal {T})$ is ...

Toll-like receptors (TLRs) play a key role in the innate immune system. TLRs recognize pathogen-associated molecular patterns and initiate an intracellular kinase cascade to induce an immediate defensive response. During recent years TLRs have become the focus of tremendous research interest. A central repository for the growing amount of relevant TLR sequence information has been created. Neve...

abstract: this paper investigates the factors accelerating smes' adoption of e-commerce. initially we proposed a model that included three categories of factors including external environmental factors, internal environmental factors and technology specifications. in addition, we proposed ecommerce adoption stages in two levels of early adoption and institutionalization. based on surveying...

Objective: Verbal fluency is a cognitive function that can be easily assessed in bedside and provide useful data for clinical assessment of a variety of cognitive functions. We decided to provide a standardized test for the assessment of verbal fluency in Persian language, including both phonemic and semantic fluency subtests.  Method: First, three letters (P, D, and Sh) and three categories (...

Using M-theory in physics, Cho, Gang, and Kim (JHEP 2020, 115 (2020) ) recently outlined a program that connects two parallel subjects of three dimensional manifolds, namely, geometric topology quantum topology. They suggest classical topological invariants such as Chern-Simons $\text{SL}(2,\mathbb{C})$-flat connections adjoint Reidemeister torsions manifold can be packaged together to produce ...
