Resonance enhancement of particle production during reheating

We found a consistent equation of reheating after inflation, which shows that for small quantum fluctuations the frequencies of resonance are slighted different from the standard ones. Quantum interference is taken into account and we found that at large fluctuations the process mimics very well the usual parametric resonance but proceed in a different dynamical way. The analysis is made in a toy quantum mechanical model and we discuss further its extension to quantum field theory.Comment: 4 pages, 4 figures(eps), using RevTe

Potential Impacts of Food Borne Ill Incidence on Market Movements and Prices of Fresh Produce in the US

For many decades, fresh fruits and vegetables enjoyed a reputation as the healthiest products full of essential vitamins, minerals, and other beneficial substances for a balanced diet. However, numerous recent food outbreaks associated with fresh produce have raised concerns on the mind of the consumer. Following an outbreak, consumers reduce their immediate consumption of the affected products. Even tough fresh fruits and vegetables have unique characteristics and flavors, consumers tend to substitute affected outbreak products with other fruits and vegetables. The potential impact of food borne illness on consumption has also a longer term impact, reducing consumption of the products over a period of several months after the outbreak. This paper used historical decomposition analysis to study both, the contemporaneous and lagged effects of food borne illness in the fresh produce industry using three case studies, spinach, cantaloupes, and tomatoes.Food safety, fresh produce, historical decomposition, Food Consumption/Nutrition/Food Safety,

Software-defined networking: guidelines for experimentation and validation in large-scale real world scenarios

Part 1: IIVC WorkshopInternational audienceThis article thoroughly details large-scale real world experiments using Software-Defined Networking in the testbed setup. More precisely, it provides a description of the foundation technology behind these experiments, which in turn is focused around OpenFlow and on the OFELIA testbed. In this testbed preliminary experiments were performed in order to tune up settings and procedures, analysing the encountered problems and their respective solutions. A methodology consisting of five large-scale experiments is proposed in order to properly validate and improve the evaluation techniques used in OpenFlow scenarios

Inflorescence initiation in grapes - response to plant growth regulators

Young pot-grown vines of Riesling grapes (Vitis vinifera L.) were treated, via roots, with gibberellin A3 (GA3), indole acetic acid (IAA), 6-benzyl-amino purine (BAP) and abscisic acid (ABA) in a factorial experiment. Seven 100 ml applications at 50 μM were applied at regular intervals. In a second experiment GA3, IAA, indole butyric acid (IBA), naphthalene acetic acid (NAA), and 2,4-dichlorophenoxy acetic acid (2,4 - D) were injected into the trunks of field-grown Riesling vines 3 weeks after bud burst. Auxins induced more leaf primordia, tendrils and inflorescences and reduced internode length in the buds of treated vines examined the following winter. The rate of formation (plastochrone) was also increased. Flowers appearing on shoots the following spring were more numerous on treated vines. GA3 had opposite effects to auxins on all the above. ABA and BAP reduced the production of tendrils, inflorescences and leaf primordia in the bud - although much less than GA3 - however, when applied with GA3, they reduced its deleterious effects on these organs. Examination of buds revealed a variety of bud forms. Buds which had more inflorescences and primordial leaves were from mature vines, especially if treated with auxin-like compounds. Young vines had fewer leaf primordia and fewer inflorescences, a situation also found in GA3 - treated older plants. Treatments or conditions which favoured more fruitful buds also tended to reduce the plastochrone and it is suggested that the two phenomena are causally related.

Incidental finding of lymphoma after septoplasty.

IntroductionSeptoplasty, or surgical correction of the deviated septum, is an elective, routinely performed rhinologic procedure to address nasal airway obstruction. In many cases, resected septal cartilage and bone fragments are sent for pathologic review, although there is no consensus on this practice. We reported two cases of incidentally diagnosed lymphoma after elective septoplasty and discussed clinical presentation, diagnosis, and management.MethodsRetrospective chart review of two patients who underwent septoplasty at a tertiary academic medical center and found to have incidental lymphoma based on histopathology.ResultsTwo patients who underwent septoplasty had an incidental diagnosis of lymphoma on pathologic analysis. One patient was noted to have an S-shaped septal deviation that produced bilateral nasal obstruction. She underwent a difficult septoplasty, in which the mucoperichondrial flap was firmly adherent to the underlying septum and bone. Final pathology demonstrated diffuse large B-cell lymphoma. She was treated with chemoradiation and remained free of disease at 59 months. The other patient had a history of nasal trauma, which produced left septal deviation. He underwent an uncomplicated septoplasty, with pathology that demonstrated low-grade B-cell lymphoma. Because there was no evidence of active disease, the decision was made to not treat and to observe the patient clinically.ConclusionsThis is the first reported series of septal lymphoma incidentally diagnosed on routine septoplasty. Although histopathologic review of specimens from routine nasal and sinus surgery is not routinely performed, this report highlighted the importance of this process, on a case-by-case basis, in detecting unexpected malignancies that otherwise were clinically silent

Quantum Error Correction in Spatially Correlated Quantum Noise

We consider quantum error correction of quantum-noise that is created by a local interaction of qubits with a common bosonic bath. The possible exchange of bath bosons between qubits gives rise to spatial and temporal correlations in the noise. We find that these kind of noise correlations have a strong negative impact on quantum error correction.Comment: 4 pages, 1 figure, final version with minor correction

Review on the effects of physical activity on body composition and shape in people with down syndrome

People with Down Syndrome (DS) are often characterized by overweight or obesity and result to be less active than their peers. Both overweight/obesity and physical inactivity are considered important risk factors for health, thus augmenting mortality risk. World Health Organization recommends different training programmes for health benefits in different age ranges of general population. Effects of physical activity may be even more important in preventing health consequences in people with DS. In this context, we conducted a literature search of original articles, published between May 2010 and May 2020, on the effects of physical activity on body shape, body composition and bone quality in people with DS. We found twelve articles from all the continents, investigating the effects of different types of physical activity on body fat and lean masses, bone composition and anthropometry. In sum, the included studies reported improvements in body composition (with augmented lean mass and reduced fat mass), body size (with lower weight, waist circumference and BMI) and bone quality (in terms of bone mineral content and/or bone mineral density). In particular, body composition improves after conditioning and plyometric jumps training program, 2-wheel bicycle training, whole body vibration and swimming. Body shape is significantly improved by bicycle training, interval training and swimming. Finally, bone quality shows positive results after conditioning and plyometric jumps training program, whole body vibration and weight bearing exercise. Although different types of physical activity are investigated in people with DS, however the best training programme for this population is not clear. So future studies may focus on the comparison or combination of different types of physical activity to assess which one could maximize benefits
