The widespread occurrence of an inverse square relation in the hierarchical distribution of subcommunities within communities (or subspecies within species) has been recently invoked as a signature of hierarchical self-organization within social and ecological systems. Here we show that, whether such systems are self-organized or not, this behavior is the consequence of the treelike classificat...

Economics-related ICT research has moved from the fringes of the discipline to penetrate all of its branches. It is, therefore, not a separate economics sub-discipline. It is also unlikely to become part of an ‘ICT or Internet Research’ proto-discipline. Instead, it should be seen as only one part of a bigger agenda toward a proper ‘information and knowledge economics’ and possibly a future pro...

INTRODUCTION The broad range of medical images and image processing technologies are applied in urology. The aim was to propose methodology to assess three-dimensional (3D) arrangement of renal arterial tree and to build a statistical model for analyzing the layout of arteries in the sections of the kidney. METHODS The series of kidney CT slices are analyzed using image processing procedures ...

Chemical doping is a normal strategy to tune thermal expansion coefficient (TEC) of ceramics in engineering applications, but the resultant TEC values usually follow Vegard’s law, as does not modify nature chemical bonding and its anharmonicity. In this paper, we report abnormal behavior (Nd1−xDyx)2Zr2O7 ceramics, where remark...

Abstract We give some adequate extension, in the framework of a general Lévy process, of our previous construction of processes with one-dimensional martingale marginals, done originally in the set-up of Brownian motion. The Lévy process framework allows us to streamline our previous arguments, as well as to reach a larger class of such processes, even in the Brownian case. We give some illustr...

The mode of agronomic traits inheritance was investigated in safflower (Carthamus tinctorius L.) in drought stress as a new report. Five generation including P1, P2, F1, F2 and F3 that derived from the cross of IL.111 (drought sensitive) ×Mex.22-191 (drought tolerance) were used in a randomized complete block design with two replic...

INTRODUCTION: Questions have a fundamental role in human and natural sciences. Many fields in human and natural sciences explore their subject matters through different kinds of questions. The team of the Ontology of Questions aims at providing a philosophical analysis and categorization of questions (except rhetorical and ironic ones), from different academic areas. Our categorization is based...

A novel 2.45 GHz self-adaptive rectifier with high efficiency and a wide input power range is proposed in this paper. It consists of high-power sub-rectifier branch, low-power an impedance transform isolation network (ITIN), feedback network. Impedance matching realized by ITIN for both branches. The design able to switch between these two branches the according its output voltage level. has be...

This study elucidates the origin of the multiplicity of stable oscillatory flows detected by time integration in tall rectangular cavities heated from the side. By using continuation techniques for periodic orbits, it is shown that initially unstable branches, arising at Hopf bifurcations of the basic steady flow, become stable after crossing Neimark-Sacker points. There are no saddle-node or p...

AIM To evaluate in vivo changes after therapy using autologous serum (AS) eye drops in Sjögren's syndrome (SS)-related dry eyes by confocal microscopy. PATIENTS AND METHODS In this study, 24 patients with SS-related dry eyes [12 in AS eye drop therapy and 12 in artificial tear (AT) therapy] and 24 healthy volunteers were recruited. Ocular Surface Disease Index (OSDI), central corneal thicknes...
