As an important epigenetic marker in identifying biological elements and processes in mammalian genomes, CpG islands (CGI) play significant roles in DNA methylation, gene regulation, epigenetic inheritance, gene mutation, chromosome inactivation and nuclesome retention. Investigating the CpG islands and their structures is a rigorous task because of unknown structures and the exponential number of...
MapReduce has become one of the most popular programming model for big data analysis in cloud systems due to its simplicity for implementing data parallel applications. There are several platforms for users to develop their applications based on MapReduce framework such as Hadoop and Twister. Hadoop is one of the most popular runtime systems for MapReduce applications and supported by various organizations,...
A dynamic COD value simulation is carried out by a simplified anaerobic digestion mathematic model (ADM). The whole anaerobic process is separated into hydrolysis stage, hydrogen and acetic acid production stage, and methane production stage. ADM 1 model is reconstruction in this paper, including assumption of the simplified anaerobic digestion model, simplify of kinetics equations of bacterial growth...
The interior-point filter algorithm (IPFA) is based on a primal-dual interior-point algorithm with a filter set which can be updated after every iteration, and the algorithm will not cycle between two points that alternately decrease the constraint violation and the barrier objective function. The simulation results from IEEE 30-bus system, IEEE 57-bus system and IEEE 118-bus system show that using...
A critical aspect of applications in Wireless Sensor Networks (WSNs) is network lifetime. Power-constrained WSNs are usable as long as they can communicate sensed data to a processing node. Poor communication links and hazard environment make the WSNs unreliable. The existing schemes only consider that the state of a sensor covering targets is in binary mode: success (cover the targets) or fail (cannot...
It is well known that there is a dynamic relationship between cerebral blood flow (CBF) and cerebral blood volume (CBV). With increasing applications of functional MRI, where the blood oxygen-level-dependent signals are recorded, the understanding and accurate modeling of the hemodynamic relationship between CBF and CBV becomes increasingly important. This study presents an empirical and data-based...
