Mapping valley bottom confinement at the network scale

Microscopy at the Bottom

About twenty years ago, many experts were still pessimistic about the possibility for making qualitative significant advancements in resolution improvement of the electron microscope. The basis for their scepticism was the Scherzer Theorem [1], which states that axially symmetric electromagnetic lenses have large intrinsic spherical and chromatic aberrations, limiting the resolution of an elect...

Mapping and Analyzing the Co-Authorship Network of Transgenic Researchers with a Network Analysis Approach

Background and Aim: Transgenic species are the ones whose genomes are genetically modified. The transgenic field is one of the areas that has a high importance and position in the world. Therefore, the aim of the present research is to draw and analyze the co-authorship network of researchers in transgenic subject area. Materials and Methods: The type of this research is descriptive and was ca...

Confinement at Weak Coupling

The free energy of U(N) and SU(N) gauge theory was recently found to be of order N to all orders of a perturbative expansion about a center-symmetric orbit of vanishing curvature. Here I consider extended models for which this expansion is perturbatively stable. The extreme case of an SU(2) gauge theory whose configuration space is restricted to center-symmetric orbits has recently been investi...

analysis of power in the network society

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
