—Stable and controllable transition from free motion to constrained motion is of central importance for robots in contact with environment in many applications. In this paper, a joint acceleration feedback control of high bandwidth is employed to damp oscillations during the contact transition when the approaching speed does not vanish. In this control(More)
Zearalenone (ZEN) is an estrogenic mycotoxin produced by several Fusarium species, which can contaminate food and feed. These compounds elicit a wide spectrum of toxic effects, including the capacity to alter normal immune function. In this study, the in vitro effects of the treatment of ConA-stimulated splenic lymphocytes with ZEN (0-25 μg/mL) were(More)
Quercetin (Que), a plant-derived flavonoid, has multiple benefical actions on the cardiovascular system. The current study investigated whether Que postconditioning has any protective effects on myocardial ischemia/reperfusion (I/R) injury in vivo and its potential cardioprotective mechanisms. Male Sprague-Dawley rats were randomly allocated to 5 groups (20(More)
This paper presents a review of recent as well as classic image copy detection method. The reviewed methods are classified as digital watermarking and contended based copy detection. The contended based copy detection usually extracts robust features from image directly that is the main difference from the digital watermarking which features are embedded(More)
Phase space reconstruction is the base of chaotic traffic flow prediction. To determine objectively the embedding delay time tau and embedding dimension m of real urban traffic flow time series chaotic phase space, we put forward a new kind of average calculation method. For delay time value, we first calculated its value of single day with auto-correlation(More)
