Time variable cosmological constant of holographic origin with interaction in Brans-Dicke theory
, 2012 Time variable cosmological constant (TVCC) of holographic origin with interaction in Brans-Dicke theory is discussed in this paper. We investigate some characters for this model, and show the evolutions of deceleration parameter and equation of state ...

On a Family of Hamilton–Poisson Jerk Systems
MathematicsIn this paper, we construct a family of Hamilton–Poisson jerk systems. We show that such a system has infinitely many Hamilton–Poisson realizations. In addition, we discuss the stability and we prove the existence of periodic orbits around nonlinearly stable equilibrium points.

The Anatomical Record, EarlyView.Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...

Time-jerk optimal deployment trajectory planning of deployable parabolic cylindrical antenna
AIP Advances, 2020 A time-jerk optimal deployment trajectory planning method of a large cable-strut deployable parabolic cylindrical antenna is proposed. First, in order to decouple the complex multi-loop mechanisms, the multi-loop basic mechanism of the deployable support

Kalman smoothing with soft inequality constraints for space robot teleoperation
International Journal of Advanced Robotic Systems, 2018 Space robot teleoperation system with haptic device has two operation modes: offline teleoperation mode and online teleoperation mode. High acceleration and jerk produced by the teleoperation system may degrade the performance of trajectory tracking and ...

Prescribing competence: The pros and cons of different methods for assessment
British Journal of Clinical Pharmacology, EarlyView.Evaluating a medical graduate’s competence in rational prescribing is challenging. With the aim to guide and inspire teachers, this narrative review explores different methods that can be used to assess prescribing competence. Each method has its own advantages and disadvantages, and thus a mix of different assessment methods is needed throughout the ...
