We introduce a two-observer all-versus-nothing proof of Bell's theorem which reduces the number of required quantum predictions from 9 to 4, provides a greater amount of evidence against local realism, reduces the detection efficiency requirements for a conclusive experimental test of Bell's theorem, and leads to a Bell inequality which resembles Mermin's inequality for three observers but requ...

All previous tests of local realism have studied correlations between single-particle measurements. In the present experiment, we have performed a Bell experiment on three particles in which one of the measurements corresponds to a projection onto a maximally entangled state. We show theoretically and experimentally that correlations between these entangled measurements and single-particle meas...

paralysis of the face of peripheral nerve origin, with acute onset. It affects 20–30 persons per 100 000 annually, and 1 in 60 individuals will be affected over the course of their lifetime. The major cause of Bell palsy is believed to be an infection of the facial nerve by the herpes simplex virus. As a result of this viral infection, the facial nerve swells and is compressed in its canal as i...

A 72-year-old woman presented left peripheral facial palsy for 1 day. Neurologic examination revealed isolated left peripheral facial palsy (figure 1). She did not have additional pontomedullary symptoms or signs, such as diplopia, abduction weakness, facial sensory loss, vertigo, nystagmus, or dysarthria. A brain diffusion-weighted MRI scan showed a hyperintense signal in the left dorsal pons ...

Ramsay Hunt Syndrome (RHS), also called Herpes Zoster Oticus (HZO), is a rare, severe complication of varicella zoster virus (VZV) reactivation in the geniculate ganglion. The classic triad consists of otalgia, vesicles in the auditory canal and ipsilateral facial paralysis [1]. Facial palsy, which occurs annually in 30 of 100 000 individuals in the general population, may have various causes, ...

OBJECTIVE To review systematically and meta-analyze the results of all randomized controlled trials (RCTs) for the treatment of patients with Bell palsy with corticosteroids vs corticosteroids plus antiviral agents. DATA SOURCES A MEDLINE, EMBASE, Cochrane Library, and CENTRAL database search, followed by extensive hand-searching for the identification of relevant studies. No time and languag...

OBJECTIVE To compare the efficacy of 2 regimens of prednisolone versus prednisolone and acyclovir in the treatment of Bell`s palsy. METHODS A retrospective study was performed on 496 Bell`s palsy patients attending Yahyanejad Hospital, Babol, Iran from 1995 to 2004, divided in 2 groups. The first group was treated with regimen one (oral prednisolone), and the second group was treated with reg...

In this evidence-based case report, the authors studied the following clinical question: What is the effect of adding antiviral agents to corticosteroids in the treatment of patients with severe or complete Bell palsy? The search yielded 250 original research articles. The 6 randomized trials of these that could be used all reported low-quality data for answering the clinical question; apart fr...

We propose a scheme to test Bell's inequalities for an arbitrary number of measurement outcomes on entangled continuous-variable (CV) states. The Bell correlation functions are expressible in terms of phase-space quasiprobability functions with complex ordering parameters, which can experimentally be determined via a local CV-qubit interaction. We demonstrate that CV systems can give higher vio...
