External guide sequences (EGSs) are oligonucleotides that consist of a sequence complementary to a target mRNA and recruit intracellular RNase P for specific degradation of the target RNA. In this study, DNA-based EGS molecules were chemically synthesized to target the mRNA coding for the protease of human cytomegalovirus (HCMV). The EGS molecules(More)
Dynamic power management (DPM) refers to strategies which selectively change the operational states of a device during runtime to reduce the power consumption based on the past usage pattern, the current workload, and the given performance constraint. The power management problem becomes more challenging when the workload exhibits nonstationary behavior(More)
Dynamic Power Management (DPM) refers to a set of strategies that achieves efficient power consumption by selectively turning off (or reducing the performance of) a system components when they are idle or are serving light workloads. This paper presents a Reinforcement Learning (RL) based DPM technique for a portable, multi-camera traffic monitoring system.(More)
A simulator is developed for training and optimizing the templates for cellular neural networks for obstacle detection. The simulator uses the Genetic Algorithm (GA) for training the cellular neural network. The traditional method of genetic algorithm involves creating an initial population of random solutions (chromosomes) in binary format, the so called(More)
The biggest challenges faced by intelligent traffic monitoring systems are mobility, compactness and energy-efficiency. Current traffic monitoring systems are based on fixed installations and thus have no or least portability. Also, they use many sensors (e.g, cameras, induction loops, radar or laser), utilize little or no image processing capabilities, and(More)
SUMO is a protein posttranslational modifier. SUMO cycle components are believed to be conserved in all eukaryotes. Proteomic analyses have lead to the identification a wealth of SUMO targets that are involved in almost every cellular function in eukaryotes. In this article, we describe the characterization of SUMO Cycle components in Hydra, a Cnidarian(More)
In this paper we describe an efficient method for traffic light controllers. This method is based on enhanced reinforcement learning with local states around each traffic light on crossings. It uses many independent controllers depending upon the number of crossings. Each controller can learn the best actions by a supervised method that is based on reward(More)
Wireless Sensor Networks (WSN) have gained remarkable appreciations over the last few years. Despite significant advantages and tremendous applications, WSN is vulnerable to variety of attacks. Due to unattended nature of WSN, sensor nodes are more prone to be overtaken by an adversary. By doing that, an adversary can learn the contents of the victim’s(More)
