In this paper we investigate the role of micropatterning and molecular coating for cell culture and differentiation of neuronal cells (Neuro2a cell line) on a polydimethylsiloxane substrate. We investigate arrays of micrometric grooves (line and space) capable to guide neurite along their axis. We demonstrate that pattern dimensions play a major role due to the deformation of the cell occasione...

This paper presents area optimization techniques for high-density spin-orbit torque magnetic random-access memories (SOT-MRAMs). Although SOT-MRAM has many desirable features of nonvolatility, high reliability and low write energy, it poses challenges to memory implementation because the use two access transistors per cell. We first analyze layout conventional bit-cell that includes vertical me...

  Background & Objectives: Cancer is a serious problem for human being and is becoming a serious problem day-by-day .A prerequisite for any therapeutic modality is early diagnosis. Automated cancer diagnosis by automatic image feature extraction procedures can be used as a feature extraction in the field of fractal dimension. The aim of this survey was to introduce a quantitative and objective...

There are remarkable relations between the graded homological dimensions and the ordinary homological dimensions. In this paper, we study the injective dimension of a complex of graded modules and derive its some properties. In particular, we define the $^*$dualizing complex for a graded ring and investigate its consequences.

‎In this paper we give an upper bound for Noetherian dimension of all injective modules with Krull dimension on arbitrary rings‎. ‎In particular‎, ‎we also give an upper bound for Noetherian dimension of all Artinian modules on Noetherian duo rings.

Two new algal species, namely, Prasiola calophylla (Prasiolaceae), and Closterium navicula (Closteriaceae) were collected from west coasts of the Caspian sea (Mazandaran province, N Iran), and runoff in south Tehran, respectively. Both the species were analyzed on the bases of morphological and anatomical characters and were determined using identification keys and interspecific comparison. Pra...
