Background SET domain bifurcated 1 (SETDB1) has been widely considered as an oncogene playing a critical role in many human cancers, including breast cancer. Nevertheless, the molecular mechanism by which SETDB1 regulates breast cancer tumorigenesis is still unknown. Methods qRT-PCR assay or western blot analysis was performed to assess the expression level of SETDB1 mRNA or protein, respectively...
Many energy-efficient asynchronous duty-cycle media access control (MAC) protocols for wireless sensor networks (WSNs) have been proposed in recent years. However, for burst traffic, most of them suffer from significant performance degradation due to randomly waking up to communicate with each other. In this paper, we propose a new asynchronous duty-cycle receiver-initiated MAC protocol called HKMAC...
FAST TCP is a new transmission control protocol designed for high speed networks. In this paper, we mainly address the stability issue of FAST TCP with time-delay. We first establish the nonlinear delay differential model of the transmission system made up of FAST TCP and the routers. Then, using the stability criterion for double time-delay system, we give the local stability condition of FAST TCP...
Check pointing is an effective fault tolerant technique to improve the reliability of large scale parallel computing systems. However, check pointing causes a large number of computation nodes to store a huge amount of data into file system simultaneously. It does not only require a huge storage space to store system state, but also brings a tremendous pressure on the communication network and I/O...
FAST TCP is a new transmission control protocol proposed for future high bandwidth-delay product networks. The stability and performance analysis of FAST TCP is an active research area. Researches show that the performance of FAST TCP, such as throughput, packet drop rate, link utilization, is sensitive to the setting of ??, which is one of the key parameter for FAST TCP. To eliminate the sensitivity,...
Network calculus is a theory of deterministic queuing systems, which is based on min-plus algebra. This paper shows a novel network calculus that based on other dioids, that is max-plus algebra. Performance bounds can be obtained by max-plus network calculus. We also do a theoretical research on max-plus network calculus by using residuation theory. Finally, we analyze guaranteed rate server as an...
FAST TCP is a newly developed transfer control protocol for future networks with high bandwidth delay product. At present, analyzing the stability of FAST TCP in different networks is an active research area. We establish a group of nonlinear delay differential equations to describe the window adjustment algorithm of FAST TCP and the queuing behavior of routers in single-link multi-source networks...
Most Active Queue Management (AQM) algorithms keep the queue length of the router at a reference value. While when the network traffic is heavy, these algorithms tend to cause high packet loss ratio, large queue oscillations, etc. To address these issues, a new method called Auto-tuning Reference Queue (ARQ) is proposed in this paper, which can be incorporated in any existing AQM algorithms with fixed...
