Some Multi-sublinear Operators on generalized Morrey spaces with non-doubling measures
Yanlong Shi,Xiangxing Tao 대한수학회 2012 대한수학회지 Vol.49 No.5
In this paper the boundedness for a large class of multi-sublinear operators is established on product generalized Morrey spaces with non-doubling measures. As special cases, the corresponding results for multilinear Calderon-Zygmund operators, multilinear fractional inte-grals and multi-sublinear maximal operators will be obtained.

In this study, we attempted to establish a culture system for in vitro spermatogenesis from spermatogonial stem cells (SSCs) of Bama mini-pig. Dissociated testicular cells from 1-month-old pigs were co-cultured to mimic in vivo spermatogenesis. The testicular cells were seeded in minimum essential medium alpha (a-MEM) supplemented with Knockout serum replacement (KSR). Three-dimensional colonies formed after 10 days of culture. The colonies showed positive staining for SSC-associated markers such as UCHL1, PLZF, THY1, OCT4, Dolichos biflorus agglutinin, and alkaline phosphatase. Induction of SSCs was performed in a-MEM + KSR supplemented with retinoic acid, bone morphogenetic protein 4, activin A, follicle-stimulating hormone, or testosterone. The results showed that STRA8, DMC1, PRM1, and TNP1 were upregulated significantly in the colonies after induction compared to that in testis from 1-month-old pigs, while expression levels of those genes were significantly low compared to those in 2-month-old testis. However, upregulation of ACROSIN was not significant. Replacement of a-MEM and KSR with Iscove’s modified Dulbecco’s medium and fetal bovine serum did not upregulate expression of these genes significantly. These results indicate that SSCs of Bama mini-pig could undergo differentiation and develop to a post-meiotic stage in α-MEM supplemented with KSR and induction factors.

Power Cable Ampacity and Influential Factors Analysis under Operation
Tong, Qiang,Qi, Jianping,Wang, Yanling,Liang, Likai,Meng, Xiangxing,Zhang, Qiang Korea Information Processing Society 2018 Journal of information processing systems Vol.14 No.5
With the increasing of urban electricity demand, making the most use of the power cable carrying capacity has become an important task in power grid system. Contrary to the rated ampacity obtained under extremely conservative conditions, this paper presents the various steady value of cable ampacity by using the changing surrounding parameters under operation, which is based on cable ampacity calculation equation under the IEC-60287 standard. To some degree, the cable ampacity analysis of actual surroundings improves the transmission capacity of cables. This paper reveals the factors that influence cable ampacity such as insulating layer thickness, allowable long-term conductor temperature, the ambient temperature, soil thermal resistance coefficient, and so on, then gives the class of the influence of these parameters on the ampacity, which plays a great role in accurately calculating the real-time ampacity and improving the utilization rate of cable in the complex external environment condition. Furthermore, the transient thermal rating of the cable is analyzed in this paper, and temperature variation of the conductor under different overload conditions is discussed, which provides effective information for the operation and control of the system.
