—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)
An antimedian of a sequence () 1 2 = , , , π k x x x  of elements of a finite metric space () , X d is an element x for which () , ∑ 1 =1 k i d x x is a maximum. The function with domain the set of all finite sequences on X , and defined by () π AM = { x : x is an antimedian of π } is called the antime-dian function on X. In this note, the antimedian(More)
Bipolar electrocautery is an effective and commonly used haemostatic technique but it may also cause iatrogenic brain trauma due to thermal injury and secondary inflammatory reactions. Progesterone has anti-inflammatory and neuroprotective actions in traumatic brain injury. However, its potential use in preventing iatrogenic brain trauma has not been(More)
