We study the self-duality operator on conic 4-manifolds. The self-duality operator can be identified as a regular singular operator in the sense of Brüning and Seeley, based on which we construct its parametrizations and closed extensions. We also compute the indexes.

a chaotic optimization algorithm (coa) based approach for the robust coordinated design of the upfc power oscillation damping controller and the conventional power system stabilizer has been investigated in this paper. chaotic optimization algorithms, which have the features of easy implementation, short execution time and robust mechanisms of escaping from local optimum, is a promising tool fo...

Molecular dynamics simulations are performed to study the cooling process of quasi-2D liquid carbon. Our results show an obvious liquid-liquid phase transition (LLPT) from the twofold coordinated liquid to the threefold coordinated liquid with the decrease of temperature, followed by a liquid-solid phase transition (LSPT). The LLPT can be regarded as the preparation stage of LSPT. During the co...

a novel potentiometric ion-selective pvc membrane sensor for analysis of atorvastatin (at) in pharmaceutical preparations based on atorvastatin-(tetraphenyl borate), (at-(tpb)2) as sensing element, tetraphenyl borate as additive and tris-2-ethyl-hexyl phosphate (top) as plasticizer solvent was prepared. the electrode shows a good nernestian response over the concentration range of 0.09–5586 µg ...

Abstract This work addresses the issue of intelligent robot–human‐coordinated parts‐to‐picker order fulfillment carried out in a human‐friendly manner. One unique feature proposed approach involves integrating real‐time data‐driven stochastic‐dynamic model with fatigue accumulation function. The optimal solutions help achieve coordination between human pickers and robots, such that robots can a...

conceptually traumatic brain injury (tbi) can be classified from a mechanistic perspective as: 1) closed, 2) penetrating, 3) blast, and 4) crush injuries. thus, tbi is a heterogeneous disease and each type of brain injury has different characteristic features often necessitating different approaches to management. the first edition of the guidelines for management and prognosis of penetrating b...

black humor plays a crucial role in fulfilling langston hughes's anti-racist purposes as an integral notionin his poetry. accordingly, translation(s) of his poetry are to benefit from the same indexes onthe basis of equivalent effect principle. on this account, 33 black-humor-rich poems of hughes, translatedby ahmad shamloo, yaghma golruee and hassan fayyad, were selected to be analyzed contras...

with development of technology and science and continuous increase in productivity, product life cycles are shortened and customer demands are more personalized and diversified, which makes companies face with ever changing and unpredictable competitive environment. therefore, rapid response to market competition has become one of the main focuses and the competitive advantages. today, one of t...
