background and objectives: studies of the relationship between personal qualities and job consequences usually find poor and inconsistent correlations. it is suggested that the reason may lie in ignorance of some modifying factors mediating such relationship. the perceived control has attracted much attention as a candidate factor. this study aimed to examine the mediating role of the perceived...

Programmable and precise regulation of dCas9 functions in response to multiple molecular signals by using synthetic gene circuits will expand the application of the CRISPR-Cas technology. However, the application of CRISPR-Cas therapeutic circuits is still challenging due to the restrictive cargo size of existing viral delivery vehicles. Here, we construct logic AND circuits by integrating mult...

A graph is König-Egerváry if the size of a minimum vertex cover equals the size of a maximum matching in the graph. We show that the problem of deleting at most k vertices to make a given graph König-Egerváry is fixedparameter tractable with respect to k. This is proved using interesting structural theorems on matchings and vertex covers which could be useful in other contexts. We also show an ...

one of the most newest concepts in the field of positive organizational scholarship (pos) is the concept “thriving at work”. thriving at work is realized when people experience learning and vitality simultaneously while doing their job tasks. if jobs are designed so that people feel thriving, organizations can exploit its positive consequences. one of the motivational approaches to job design i...

the purpose of this paper is to study the degree of job satisfaction of the employees of khorassan general administration for technical and vocational training and the related factors. the study has been carried out using the sampling method, with the statistical society of the survey consisting of 690 persons, and the sample size of 512 persons. the results shows that independent variables rel...

A new method for decision-tree-based recommender systems is proposed. The proposed method includes two new major innovations. First, the decision tree produces lists of recommended items at its leaf nodes, instead of single items. This leads to reduced amount of search, when using the tree to compile a recommendation list for a user and consequently enables a scaling of the recommendation syste...

A Compact Corner Split Ring with C Slot Rectangular Microstrip Patch Antenna fed by a 50 Ω microstripline is discussed. split ring shaped slot has been etched in rectangular microstrip antenna. The increases the length of surface current for dominant mode TM10 leading to decrease resonance frequency. Size reduction and hexaband obtained proposed antenna provides both size best suited wireless c...

We discuss matrix partition problems for graphs that admit a partition into k independent sets and ` cliques. We show that when k + ` 6 2, any matrix M has finitely many (k, `) minimal obstructions and hence all of these problems are polynomial time solvable. We provide upper bounds for the size of any (k, `) minimal obstruction when k = ` = 1 (split graphs), when k = 2, ` = 0 (bipartite graphs...

Splitting the liver for two adults to increase the donor pool is still a debated issue, especially for combined organ transplantation. We described a case of liver-splitting procedure for two adults, which was successful even in the presence of combined organ transplantation. Three adult combined organ transplantations from one deceased donor were performed, with, use of split liver grafts in t...

Gaussian split Ewald (GSE) is a versatile Ewald mesh method that is fast and accurate when used with both real-space and k-space Poisson solvers. While real-space methods are known to be asymptotically superior to k-space methods in terms of both computational cost and parallelization efficiency, k-space methods such as smooth particle-mesh Ewald (SPME) have thus far remained dominant because t...
