Open AccessPiperlongumine conquers temozolomide chemoradiotherapy resistance to achieve immune cure in refractory glioblastoma via boosting oxidative stress-inflamation-CD8+-T cell immunity
The failure of novel therapies effective in preclinical animal models largely reflects the fact that current models do not really mimic the pathological/therapeutic features of glioblastoma (GBM), in which the...

Open AccessPhysiological and developmental traits associated with the grain yield of winter wheat as affected by phosphorus fertilizer management
Although researchers have determined that attaining high grain yields of winter wheat depends on the spike number and the shoot biomass, a quantitative understanding of how phosphorus (P) nutrition affects spi...

Applications of lagrangian coherent structures to expression of invariant manifolds in astrodynamics
This paper investigates the relationship between invariant manifold and Lagrangian coherent structure (LCS) in dynamical systems. LCS is defined as the ridge of finite-time Lyapunov exponent (FTLE) field, and ...

Dynamics and adaptive control of a dual-arm space robot with closed-loop constraints and uncertain inertial parameters
A dynamics-based adaptive control approach is proposed for a planar dual-arm space robot in the presence of closed-loop constraints and uncertain inertial parameters of the payload. The controller is capable o...

Controllability of an underactuated spacecraft with one thruster under disturbance
For an underactuated spacecraft using only one thruster, the attitude controllability with respect to the orbit frame is studied in the presence of periodical oscillation disturbance, which provides a precondi...

Displaced orbits generated by solar sails for the hyperbolic and degenerated cases
Displaced non-Keplerian orbits above planetary bodies can be achieved by orientating the solar sail normal to the sun line. The dynamical systems techniques are employed to analyze the nonlinear dynamics of a ...
