Kytmanov and Myslivets gave a special Cauchy principal value of the singular integral on the bounded strictly pseudoconvex domain with smooth boundary. By means of this Cauchy integral principal value, the corresponding singular integral and a composition formula are obtained. This composition formula is quite different from usual ones in form. As an application, the corresponding singular integral equation and the system of singular integral equations are discussed as well. 展开更多

In this paper we introduce two sequences of operator functions and their dualfunctions: fk(t) = (flogt)k-(t-1)k/log^k+2t (k = 1,2,...), gk(t) = (t-1)k-logkt /log^k+1t (k = 1,2,...) and fk(t)tklog^k... In this paper we introduce two sequences of operator functions and their dualfunctions: fk(t) = (flogt)k-(t-1)k/log^k+2t (k = 1,2,...), gk(t) = (t-1)k-logkt /log^k+1t (k = 1,2,...) and fk(t)tklog^k+1t/(tlogt)k-(t-1)^k(k=1,2…),gk(t)=t^klog^k+1t/(t-1)^k-log^kt(k=1,2…)defined onWe find that they are all operator monotone functions with respect to the strictly chaoticorder and some ordinary orders among positive invertible operators. Indeed, we extend theresults of the operator monotone function tlogt-t+1/log^2t which is widely used in the theory of heat transfer of the heat engineering and fluid mechanics[1]. 展开更多

Being an important part of the "four comprehensives" strategic thinking in an all-round way, the comprehensive and strict governance on the paxty has promoted the position of the construction of the party in constructing the socialism with Chinese characteristics. From the "strict governance on the pasty" to the "comprehensive and strict governance on the party," it doesn't only mean that the "comprehensive" word is added in literal, but the content of innovation and requirements should be improved, and it has the following rules: Our country should adhere to combine the establishment of the ideological paxty and the governance of the institutional pasty, and our country should adhere to combine the comprehensive and strict governance on the pasty and the control of the "key minority." Our country should adhere to the combination of strengthening the main responsibility and playing the role of people's supervision and also should adhere to combine the strict punishment with the effective prevention. 展开更多

DEAR EDITOR,We identified strict monandry in a wandering wolf spider species(Pardosa pseudoannulata) and revealed the underlying mechanisms of this mating structure. Evidence indicated that males damaged the inner walls of the female genital tract with the sharp part of their intromittent organ during insemination. The traumatic mating caused hemolymph hemorrhage, which mixed with seminal fluid and gradually formed an impermeable amorphous mating plug after about15 days, completely blocking the female copulatory opening. 展开更多
