Codon usage bias is a universal feature of eukaryotic and prokaryotic genomes and has been proposed to regulate translation efficiency, accuracy, and protein folding based on the assumption that codon usage affects translation dynamics. The roles of codon usage in translation, however, are not clear and have been challenged by recent ribosome profiling(More)
Aerial dispersal miniature reconnaissance robots can be used in many areas such as natural disasters, man-power disasters, military reconnaissance and so on. Due to its characteristics of fast response, long detection distance and large coverage area, aerial dispersal miniature reconnaissance robots are suitable for these situations mentioned above.(More)
A secondary optimization technique was proposed to estimate the temperature-dependent thermal conductivity and absorption coefficient. In the proposed method, the stochastic particle swarm optimization was applied to solve the inverse problem. The coupled radiation and conduction problem was solved in a 1D absorbing, emitting, but non-scattering slab(More)
This paper is authored to describe a control framework that is designated for hydraulically actuated quadruped robot to trot on rough terrain. In order to succeed in trotting on rough terrain, two controllers are synthesized: i) Dual Length Linear Inverted Pendulum Method (DLLIPM), ii) Active Compliance Control. The first controller computes the hydraulic(More)
Coal mine is a very dangerous field because various fatal factors menace people especially when coal mine explosion happens. For the reason that rescuers have to know the mine tunnel actual situation and at the same time, it is very dangerous for rescuers to go into mine tunnel because of the unknown environment, a kind of coal mine detect robot and an(More)
Miniature robots can't carry too many sensors for obstacle avoidance due to its small volume. In this paper, we applied the method based on low-cost local map for obstacle avoidance that uses infrared sensors and MPU6050. Firstly, we introduced the robot and its kinematic model. Secondly, proposed the criterion of robot be trapped. Thirdly, we studied the(More)
The map building is the prerequisite in the mobile robots' autonomous operation in an unknown environment. Most current mobile robots mainly use the 2D map, and the others which use the 3D map have some shortcomings such as the complex data processing algorithm, large computation and time-consuming and so on. The paper presents a 3D data scanning system(More)
Miniature robot has becoming a preferable choice for outdoor reconnaissance task due to its flexibility. However, miniature robot tends to have poor navigation ability because of the limited perception ability coming with the constrained space. This paper focus on the navigation problem of outdoor miniature reconnaissance robot with limited sensing ability(More)
When the robot appears, various researches on it have been coming out one after the other and changing rapidly. The robotics is refined day after day. Especially in the recent decades, with the emergence and developments of internet and the computers, it makes a remarkable progress and reaches an unprecedented level. The robot is of wide applications(More)
Codon usage biases are found in all eukaryotic and prokaryotic genomes and have been proposed to regulate different aspects of translation process. Codon optimality has been shown to regulate translation elongation speed in fungal systems, but its effect on translation elongation speed in animal systems is not clear. In this study, we used a Drosophila(More)
