Background and Aims
Proteins that recognize epigenetic modifications function as mediators to interpret epigenetic codes. Hypoxia response and metabolic rewiring are two major events during cancer progression. However, whether and how the epigenetic regulator integrates hypoxia response and metabolism together remain open for study.

For the lacking of inspection method, the transportation data standards are compiled weakly in the process of transportation information system developing, which increases the difficulty of data sharing and exchange. In order to improve the conformance of data with the standards of transportation information systems, a method named “data standard conformance inspection” is proposed in this paper....
The model predictive control (MPC) strategy with a control Lyapunov function (CLF) as terminal cost is commonly used for its guaranteed stability. In most of the cases, CLF is locally designed, and the region of attraction is limited, especially when under control constraints. In this article, the stability and the region of attraction of constrained MPC that is applied to the discrete-time nonlinear...
For the multi-channel ground moving target indication (GMTI) system in the aircraft platform, the channel mismatch will degrade the detection probability for moving targets, since the correlation property of the clutter between channels is decreased. In this paper, a novel channel equalization approach is presented, which uses the spatial correlation property of ground clutters from multi-channels...
The present micro aerial vehicle (MAV) is lack of maneuverability and security when operates in the restricted environment. To solve such problem, a rotor powered disk-type autonomous aircraft—Micro Aerial Robot(MAR) was designed, which adopts built-in blades and redundant actuators structure to enhance vehicle's safety and robustness, and adopts the inner and outer two rotor systems and disk-type...
The paper presents a kind of URAV(unmanned rotor aerial vehicle)which can be reconfigurable controlled. Its actuators include the major rotor inside the duct, four auxiliary rotors surrounding the major rotor and two ailerons at the end of the duct. The auxiliary rotors have the similar functions as that of the major rotor and ailerons in order to make the system to own the ability of reconfigurable...
In order to overcome the shortcomings of the dynamic structure of the ducted-fan aircraft, the paper proposes a new design of the disk-typed autonomous aerial robot based on rotor aerodynamic, named Micro aerial robot(MAR). MAR adopts inner and outer double-rotor system and disk-type body structure, and has some unique dynamic characters. Using the Newton-Euler modeling method, a six degrees of freedom(6...
The flexible two-wheeled balancing robot is a non-stable, non-linear, strong coupling system. A Kalman filter configuration combining a gyroscope and an inclinometer is implement to obtain an accurate estimate of the tilt angle and its derivate. This paper also presents nonlinear PID controller for the posture balancing control of FTWSBR, The experiment results demonstrate that the control method...
