Gravitational decoherence: A general nonrelativistic model

We derive a general quantum master equation for the dynamics of a scalar bosonic particle interacting with a weak, stochastic and classical external gravitational field. The dynamics predicts decoherence in position, momentum and energy. We show how our master equation reproduces the results present in the literature by taking appropriate limits, thus explaining the apparent contradiction in their dynamical description. Our result is relevant in light of the increasing interest in the low energy quantum-gravity regime

Gravitational Decoherence and the Possibility of Its Interferometric Detection

We present a general master equation describing the quantum dynamics of a scalar bosonic field interacting with an external weak and stochastic gravitational field. The dynamics predicts decoherence both in position and in energy momentum. We show how the master equation reproduces, thus generalizing, the previous results in the literature by taking appropriate limits. We estimate the effect of gravitational decoherence in atom interferometers, providing also a straightforward way to assess the magnitude of the effect

Relieving laryngopharingeral reflux (relief) survey in otolaryngology - The viewpoint of the otorhinolaryngologist

Laryngopharyngeal Reflux (LPR) should be considered as part of extraesophageal reflux (EER). This reflux involves respiratory structures other than, or in addition to, the oesophagus. A new medical device for the treatment of gastric reflux, including LPR, has been launched in Italy: Marial®. Therefore, the aim of the present survey was to analyse the prescriptive behaviour both considering the past or current treatments and clinical features during a specialist routine visit. The current survey was conducted in 86 Otorhinolaryngological centers, distributed in all of Italy. Globally, 4.418 subjects [47% males and 53% females, 50.1 (14.5) years-of-Age] were visited. The visits included laryngoscopy, Reflux Finding Score (RFS) and Reflux Symptom Index (RSI) questionnaires. The total RSI median score was 15 (12-19) and the total median RFS value was 10 (8-12). Interestingly, a significant change in the new drug prescription was observed (p<0.0001): over two-Third of patients (67%) received Marial® as monotherapy, whereas PPI plus add-on were prescribed to almost one-Third of the patients. PPI alone was prescribed in less than 1 %. In conclusion, LPR is a common disorder characterized by typical signs and symptoms; LPR patients may be correctly identified and scored by evidence-based criteria. In addition, the present survey reported that LPR treatment has been considerably changed by the introduction of a new medical device

Correlation between the reflux finding score and the reflux symptom index in patients with laryngopharyngeal reflux

LaryngoPharyngeal Reflux (LPR) is characterized by symptoms, signs, and/or tissue damage resulting from the aggression of the gastrointestinal contents in the upper airways. The Reflux Finding Score (RFS) assesses the laryngeal signs through laryngoscopy. The Reflux Symptom Index (RSI) scores the LPR symptoms. The objective of this real-world study was to compare RFS with RSI in a cohort of Italian LPR patients. Globally, 3932 patients with LPR were evaluated and RFS and RSI were assessed in all subjects. A moderate correlation was found between RSI and RFS (r=0.484, p<0.0001). In conclusion, the RSI and RFS can easily be included in the LPR work-up as objective and consistent parameters, with low cost and high practicality. Based on these clinical outcomes, the specialist can easily use these tests in clinical practice
