For a robot situated in a dynamic real world environment the knowledge of its position and orientation is very advantageous and sometimes essential for carrying out a given task. Particularly, one would appreciate a robust, accurate and efficient selflocalization method which allows a global localization of the robot. In certain polygonal environments a laser based localization method is capabl...

Metformin, a widely used first-line drug for treatment of type 2 diabetes (T2D), has been shown to extend lifespan and delay the onset of age-related diseases. However, its primary locus of action remains unclear. Using a pure in vitro reconstitution system, we demonstrate that metformin acts through the v-ATPase-Ragulator lysosomal pathway to coordinate mTORC1 and AMPK, two hubs governing meta...

The Kennedy Class I and II distal extension situation poses a challenge to the prosthodontist as it inherently possesses a lack of stability, which may be attributed to the difference in compressibility of the mucosa and the periodontal ligament surrounding the distal-most abutment tooth. This results in a rotational tendency of the prosthesis around the line connecting its terminal abutments. ...

the purpose of this study was investigation of east azerbaijan researchers and extension agents’ view about the role of extension services on agricultural development. the methodology was descriptive-correlation which is carried out by survey method. in this study, the sample population was 335 people including all researchers and extension agents working in the agricultural sector. to assess t...

Companies are increasingly adopting a product-line approach to the development of safety-critical systems. A product line offers large-scale reuse by exploiting common features and assets shared by systems within a specific domain. In this paper, we discuss the challenges of justifying the safety of architectural configurations and variation when developing product-line safety cases. We then ad...

We present PLTplot, a plotting package for PLT Scheme. PLTplot provides a basic interface for producing common types of plots such as line and vector field plots from Scheme functions and data, an advanced interface for producing customized plot types, and support for standard curve fitting. It incorporates renderer constructors, transformers from data to its graphical representation, as values...

A graph is called normal if its vertex set can be covered by cliques Q1, Q2, . . . , Qk and also by stable sets S1, S2, . . . , Sl, such that Si ∩ Qj 6= ∅ for every i, j. This notion is due to Körner, who introduced the class of normal graphs as an extension of the class of perfect graphs. Normality has also relevance in information theory. Here we prove, that the line graphs of cubic graphs ar...
