In this work, we propose an approach for computing the compromised solution of an LR fuzzy linear system by using of a ranking function when the coefficient matrix is a crisp mn matrix. To do this, we use expected interval to find an LR fuzzy vector, X , such that the vector (AX ) has the least distance from (b) in 1 norm and the 1 cut of X satisfies the crisp linear system AX = b ...

background: mesenchymal stem cells (mscs) are ideal cells for cell and gene therapy. however, the low survival of mscs after transplantation has limited their applications. we aimed to evaluate the expression of cytoprotective genes including nqo1, txnrd1, ho-1, gclc following the over expression of nrf2 in umbilical cord-derived mscs (uc-mscs). methods: 3-5 passages of uc-mscs were cultured. r...

In this paper, we have dened and studied a generalized form of topological vector spaces called s-topological vector spaces. s-topological vector spaces are dened by using semi-open sets and semi-continuity in the sense of Levine. Along with other results, it is proved that every s-topological vector space is generalized homogeneous space. Every open subspace of an s-topological vector space is...

‎We consider four-dimensional lie groups equipped with‎ ‎left-invariant Lorentzian Einstein metrics‎, ‎and determine the harmonicity properties ‎of vector fields on these spaces‎. ‎In some cases‎, ‎all these vector fields are critical points for the energy functional ‎restricted to vector fields‎. ‎We also classify vector fields defining harmonic maps‎, ‎and calculate explicitly the energy of t...

background: prediction of interaction sites within the membrane protein complexes using the sequence data is of a great importance, because it would find applications in modification of molecules transport through membrane, signaling pathways and drug targets of many diseases. nevertheless, it has gained little attention from the protein structural bioinformatics community. methods: in this stu...

In this paper, a vector version of the intermediate value theorem is established. The main theorem of this article can be considered as an improvement of the main results have been appeared in [textit{On fixed point theorems for monotone increasing vector valued mappings via scalarizing}, Positivity, 19 (2) (2015) 333-340] with containing the uniqueness, convergent of each iteration to the fixe...

Background: Type-1 diabetes (T1D) is an autoimmune disease in which T lymphocytes destroy insulin-producing β-cells. Control of self-reactive T lymphocytes and recovery of diabetic injury is the end point of T1D. Objective: To investigate generation of tolerogenic dendritic cells (tolDCs) as an innovative method of diabetes therapy. Methods: Lentivirus vector production was achieved by GIPZ mou...

Recently, gene therapy vectors based upon the human immunodeficiency virus type 1 (HIV-1) genome have been developed. Here, we create an HIV-1 vector which is defective for all HIV-1 genes, but which maintains cis-acting elements required for efficient packaging, infection, and expression. In T cells transduced by this vector, vector expression is low but efficiently induced following HIV-1 inf...

The vast interstellar void of space has an annoying habit of occasionally containing stray electromagnetic waves that interfere with your communications back home; when you send a signal back home (in binary, naturally), occasionally one of your 1’s will be switched into a 0, or vice-versa. Assume that no more than one out of three consecutive bits in any message you send will be scrambled. How...
