The history of non-invasive mechanical ventilation goes back more than 100 years, but it was not until 1987 when what we could call "modern" non-invasive mechanical ventilation was developed. The description of Delaubier and Rideau of a patient with Duchenne's disease who had been effectively ventilated through a nasal mask marked the start of a new era in the history of non-invasive mechanical...

Purpose: Traditional approaches to mechanical debridement of the tooth surface to remove tooth accretions continue to be an integral part of periodontal therapy. The purpose of the present study was to test the effectiveness of mechanical non-surgical therapy in subjects with moderate to severe gingivitis and periodontitis. Methods: Ten subjects of moderate to severe gingivitis/periodontits wer...

To circumvent the disadvantages of endoscopic dacryocystorhinostomy such as small rhinostomy size, high failure rate and expensive equipment, we hereby introduce a modified technique of non-endoscopic mechanical endonasal dacryocystorhinostomy (NE-MEDCR). Surgery is performed under general anesthesia with local decongestion of the nasal mucosa. A 20-gauge vitrectomy light probe is introduced th...

We study the effects of post-selection measurements on both the non-classicality of the state of a mechanical oscillator and the entanglement between two mechanical systems that are part of a distributed optomechanical network. We address the cases of both Gaussian and nonGaussian measurements, identifying in which cases simple photon counting and Geiger-like measurements are effective in disti...

Acute respiratory distress syndrome (ARDS) is an acute hypoxemic respiratory failure with lung oedema of non cardiac origin. Its primary treatment is mechanical ventilation. ARDS is under the spotlights with influenza A pandemic flu. An operating definition has been set out by an experts-consensus conference in order to include patients in clinical trials. However, this definition lacks diagnos...

In this letter we establish the impossibility of existence of self replicating machine in the quantum world. We established this result by three different but consistent ways of linearity of quantum mechanics, no signalling criterion and conservation of entanglement under LOCC.

A non-repudiation protocol of Zhou and Gollmann [18] has been mechanically verified. A non-repudiation protocol gives each party evidence that the other party indeed participated, evidence sufficient to present to a judge in the event of a dispute. We use the theorem-prover Isabelle [10] and model the security protocol by an inductive definition, as described elsewhere [1, 12]. We prove the pro...

Recent research in infant cognition and adult vision suggests that the mechanical object relationships may be more salient and naturally attention grabbing than similar but non-mechanical relationships. Here we examine two novel sources of evidence from language related to this hypothesis. In Experiments 1 and 2, we show that adults preferentially infer that the meaning of a novel preposition r...

STUDY OBJECTIVE Noninvasive mechanical ventilation (NIMV) is beneficial for patients with acute respiratory failure (ARF) when added to medical treatment. However, its role as an alternative to conventional mechanical ventilation (CMV) remains controversial. Our aim was to compare the efficacy and resource consumption of NIMV against CMV in patients with ARF. DESIGN A randomized, multicenter,...
