With the advent of quantum information, the violation of a Bell inequality is used to witness the absence of an eavesdropper in cryptographic scenarios such as key distribution and randomness expansion. One of the key assumptions of Bell's theorem is the existence of experimental "free will," meaning that measurement settings can be chosen at random and independently by each party. The relaxati...

After completing a three-year (1995-97) evaluation of bell pepper cultivars under induced bacterial spot (Xanthomonas campestris pv. vesicatoria or Xcv) and bacterial spot-free environments, we began a new series of trials in 2000 to compare new cultivars with previously recommended cultivars that were either highly resistant (‘Boynton Bell’) and/or that had very attractive fruits (‘X3R Wizard’...

This study provides historical documents of peripheral facial palsy from Egypt, Greece and Rome, through the middle ages, and the renaissance, and into the last four centuries. We believe that the history of peripheral facial palsy parallels history of the human race itself. Emphasis is made on contributions by Avicenna and Nicolaus Friedreich. Controversies about the original clinical descript...

Spontaneous carotid-cavernous fistulae are uncommon. They are seen mostly in association with hypertension, atherosclerosis or intracranial aneurysm (Bickerstaff, 1970). Facial palsy was noted by Walsh (1957) in a case of traumatic carotid-cavernous fistula which recovered in one year. Involvement of the third, fourth, fifth and sixth cranial nerves has been frequently noted (Walsh, 1957; Sattl...

We derive tight Bell's inequalities for N>2 observers involving more than two alternative measurement settings. We give a necessary and sufficient condition for a general quantum state to violate the new inequalities. The inequalities are violated by some classes of states, for which all standard Bell's inequalities with two measurement settings per observer are satisfied.

Quantum teleportation strikingly underlines the peculiar features of the quantum world. We present an experimental proof of its quantum nature, teleporting an entangled photon with such high quality that the nonlocal quantum correlations with its original partner photon are preserved. This procedure is also known as entanglement swapping. The nonlocality is confirmed by observing a violation of...

We investigate the nonlocal properties of graph states. To this aim, we derive a family of Bell inequalities which require three measurement settings for each party and are maximally violated by graph states. In turn, for each graph state there is an inequality maximally violated only by that state. We show that for certain types of graph states the violation of these inequalities increases exp...

PURPOSE The aim of this study was to establish normative values and to identify age-related change in physical examinations that are commonly used while evaluating patients with cerebral palsy (CP). MATERIALS AND METHODS One hundred four healthy volunteers (mean age 36 years, standard deviation 15 years) were enrolled and divided into four age groups: 13-20, 21-35, 36-50, and 51 years and old...

AIM The aim of the study was to investigate whether impairments associated with cerebral palsy were stable between childhood and adolescence. METHOD The Study of Participation of Children with Cerebral Palsy Living in Europe (SPARCLE) longitudinal study was conducted in nine European regions. In total, 818 children aged 8 to 12 years were randomly selected from population-based registers; 594...
