Nasal and conjunctival screening prior to refractive surgery: an observational and cross-sectional study

Objectives To investigate bacterial flora of clinically healthy conjunctiva and nasal cavity among patients prior to refractive surgery, as well as the characteristics of patients with methicillin-resistant Staphylococcus aureus (MRSA) colonisation. Design Observational and cross-sectional study. Setting A single-centre study in Japan. Participants 120 consecutive patients pre-refractive surgery. Primary and secondary outcome measures methods Samples were obtained from the right conjunctival sac and the nasal cavity of 120 consecutive patients prior to refractive surgery and were then measured for the levels of the minimum inhibitory concentration (MIC) of antibiotics. Patients were interviewed regarding their occupation, family living situation and any personal history of atopic dermatitis, asthma, smoking or contact lens wear. Results Propionibacterium acnes (P. acnes) (32.5%) and Staphylococcus epidermidis (4.2%) were detected from the conjunctival sac. S. epidermidis was the most commonly isolated (68.3%) in the nasal cavity. Of the 30 patients (25.0%) with colonisation by S. aureus, 2 patients, both of whom were healthcare workers with atopic dermatitis, were found to be positive for MRSA in the nasal cavity. A history of contact lens wear, asthma or smoking, as well as patient gender and age, was not associated with MRSA colonisation. Conclusions There were only 2 patients who were colonised with MRSA, both of whom were healthcare workers with atopic dermatitis. P. acnes was predominantly found in the conjunctival sac. Further study is needed to investigate the involvement between nasal and conjunctival flora, and risk factors for infectious complications.
Continuity of the measure of the spectrum for discrete quasiperiodic operators

We study discrete Schrodinger operators (H�,�ψ)(n) = ψ(n − 1) + ψ(n + 1) + f(αn+θ)ψ(n) on l 2 (Z), where f(x) is a real analytic periodic function of period 1. We prove a general theorem relating the measure of the spectrum of H�,� to the measures of the spectra of its canonical rational approximants under the condition that the Lyapunov exponents of H�,� are positive. For the almost Mathieu operator (f(x) = 2λcos2πx) it follows that the measure of the spectrum is equal to 4|1 − |λ|| for all real θ, λ 6 ±1, and all irrational α.
Sales Professional's Commitment to Smile: Is Social Support a Moderator between Emotional Labour and its Consequences on Well-being?

A pre-requisite for sales professionals is to exhibit positive emotional outlook during service encounters so as to influence the customer’s buying decisions and ultimately their satisfaction level. The present study evaluates how the performance of emotional labour strategies during service encounter has a consequential effect (i.e., emotional exhaustion and psychological distress) on the sales professionals. Further, the study investigates the moderating role of social support in the relationship between emotional labour performed by the sales professionals and its consequences on their well-being in the context of organised retail service. Using structured schedules, the data was collected from 600 sales professionals employed in the Indian organised retail industry (branded clothing retail stores) in Delhi NCR and to analyse the data, moderated multiple regression analysis was carried out. Based on the findings of the study, the implications in the workplace and recommendation for future studies are suggested.
Tumor stage, human papillomavirus and smoking status affect the survival of patients with oropharyngeal cancer: an Italian validation study.

BACKGROUND Tumor human papillomavirus (HPV) status strongly affects overall survival (OS) of oropharyngeal cancer (OPC) patients. Recently, three groups with different outcomes were identified based on HPV status, smoking history and tumor stage. Our objective was to validate this model using a single-institutional retrospective database. PATIENTS AND METHODS Patients (n=120) diagnosed with OPC at our institution, treated with concomitant cisplatin plus radiotherapy (RT) (n=64), induction chemotherapy followed by concomitant chemoradiation (n=39) or RT alone (n=17), were stratified in three groups with respect to the risk of death (low 26, intermediate 46 and high 49 patients) according to tumor p16 expression as surrogate of HPV status, pack-years of tobacco smoking and nodal/tumor stage. Group-stratified Kaplan-Meier OS curves were estimated and compared using the log-rank test. RESULTS The 2-year OS estimates were 100%, 86% and 70%, respectively. The difference between the survival curves was statistically significant (P=0.009). The Harrell's concordance index was 0.70. The calibration plot showed a good concordance between our results and those observed in the original study. CONCLUSIONS This study validates the risk grouping previously identified. Risk-driven clinical decision making and trial designs will help in better defining the most appropriate treatment in OPC patients.

Three experiments investigated the role of attention in visual priming across rotations in the picture plane. Experiment 1 showed that naming latencies increased with the degree of misorientation for objects commonly seen in an upright view (base objects) but not for objects seen familiarly from many views (no-base objects). In Experiment 2, no-base objects revealed a priming pattern identical to that observed previously for left Áright reflections (Stankiewicz, Hummel, & Cooper, 1998): Attended objects primed themselves in the same and rotated views, whereas ignored images primed themselves only in the same view, with additive effects of attention and orientation. In Experiment 3 ignored base objects only primed themselves in a familiar (upright) view, indicating that priming only obtains when that image makes contact with object memory. These data challenge theories of object recognition that rely on any single representation of shape and contribute to evidence suggesting holistic (view-like) representations for ignored and analytic (view-insensitive) representations for attended objects. The human capacity for visual object recognition is characterized by a complex pattern of strengths and limitations that defy explanation in terms of simple ''one size fits all'' accounts of the representation of object shape or the processes that generate those representations and match them to object memory. For example, consider our apparent ability to recognize familiar objects in novel views; this led many researchers Sutherland, 1968) to postulate that we represent objects as structural descriptions. Structural representations specify an object's parts, typically volumetric parts, such as geons (Biederman, 1987) or generalized cylinders (Marr & Nishihara, 1978), in terms of their spatial relations to one another. A structural description of a coffee mug might represent its shape (approximately) as a ''curved cylinder side-attached to a vertical straight …
Quantum Transport in an Aharonov‐Bohm Electron Interferometer

We report experiments on quantum electron interferometers fabricated from GaAs/AlGaAs heterojunctions. In this kind of devices, an electron island with two nearly open constrictions is defined by etched trenches. In the quantum Hall (QH) regime, two counterpropagating edge channels are coupled by tunneling in the constrictions, thus forming a closed interference path. We observe periodic Aharonov‐Bohm oscillations in the four‐terminal magnetoresistance on the i = 1, 2 and 4 QH plateaus. The period of the oscillations ΔB scales with i so that iΔB = const = 2.7±0.1 mT. For i = 1, we determine the dependence of the area enclosed by the electron interference path on the front‐gate voltage, and find a constant integrated compressibility of the island electron system with respect to the front gates. We further compare the experimental results with two classical electrostatics models of the electron density profile in the island.
Proteomic Analysis of the Secretory Response of Aspergillus niger to D-Maltose and D-Xylose

Fungi utilize polysaccharide substrates through extracellular digestion catalyzed by secreted enzymes. Thus far, protein secretion by the filamentous fungus Aspergillus niger has mainly been studied at the level of individual proteins and by genome and transcriptome analyses. To extend these studies, a complementary proteomics approach was applied with the aim to investigate the changes in secretome and microsomal protein composition resulting from a shift to a high level secretion condition. During growth of A. niger on d-sorbitol, small amounts of d-maltose or d-xylose were used as inducers of the extracellular amylolytic and xylanolytic enzymes. Upon induction, protein compositions in the extracellular broth as well as in enriched secretory organelle (microsomal) fractions were analyzed using a shotgun proteomics approach. In total 102 secreted proteins and 1,126 microsomal proteins were identified in this study. Induction by d-maltose or d-xylose resulted in the increase in specific extracellular enzymes, such as glucoamylase A on d-maltose and β-xylosidase D on d-xylose, as well as of microsomal proteins. This reflects the differential expression of selected genes coding for dedicated extracellular enzymes. As expected, the addition of extra d-sorbitol had no effect on the expression of carbohydrate-active enzymes, compared to addition of d-xylose or d-maltose. Furthermore, d-maltose induction caused an increase in microsomal proteins related to translation (e.g., Rpl15) and vesicular transport (e.g., the endosomal-cargo receptor Erv14). Millimolar amounts of the inducers d-maltose and d-xylose are sufficient to cause a direct response in specific protein expression levels. Also, after induction by d-maltose or d-xylose, the induced enzymes were found in microsomes and extracellular. In agreement with our previous findings for d-xylose induction, d-maltose induction leads to recruitment of proteins involved in proteasome-mediated degradation.
Potential for Plant Growth Promotion of Rhizobacteria Associated with Salicornia Growing in Tunisian Hypersaline Soils

Soil salinity and drought are among the environmental stresses that most severely affect plant growth and production around the world. In this study the rhizospheres of Salicornia plants and bulk soils were collected from Sebkhet and Chott hypersaline ecosystems in Tunisia. Depiction of bacterial microbiome composition by Denaturing Gradient Gel Electrophoresis unveiled the occurrence of a high bacterial diversity associated with Salicornia root system. A large collection of 475 halophilic and halotolerant bacteria was established from Salicornia rhizosphere and the surrounding bulk soil, and the bacteria were characterized for the resistance to temperature, osmotic and saline stresses, and plant growth promotion (PGP) features. Twenty Halomonas strains showed resistance to a wide set of abiotic stresses and were able to perform different PGP activities in vitro at 5% NaCl, including ammonia and indole-3-acetic acid production, phosphate solubilisation, and potential nitrogen fixation. By using a gfp-labelled strain it was possible to demonstrate that Halomonas is capable of successfully colonising Salicornia roots in the laboratory conditions. Our results indicated that the culturable halophilic/halotolerant bacteria inhabiting salty and arid ecosystems have a potential to contribute to promoting plant growth under the harsh salinity and drought conditions. These halophilic/halotolerant strains could be exploited in biofertilizer formulates to sustain crop production in degraded and arid lands.
A Taxonomy of Deep Convolutional Neural Nets for Computer Vision

Traditional architectures for solving computer vision problems and the degree of success they enjoyed have been heavily reliant on hand-crafted features. However, of late, deep learning techniques have offered a compelling alternative -- that of automatically learning problem-specific features. With this new paradigm, every problem in computer vision is now being re-examined from a deep learning perspective. Therefore, it has become important to understand what kind of deep networks are suitable for a given problem. Although general surveys of this fast-moving paradigm (i.e. deep-networks) exist, a survey specific to computer vision is missing. We specifically consider one form of deep networks widely used in computer vision - convolutional neural networks (CNNs). We start with "AlexNet" as our base CNN and then examine the broad variations proposed over time to suit different applications. We hope that our recipe-style survey will serve as a guide, particularly for novice practitioners intending to use deep-learning techniques for computer vision.

Dual and Opposing Modulatory Effects of Serotonin on Crayfish Lateral Giant Escape Command Neurons

Serotonin modulates afferent synaptic transmission to the lateral giant neurons of crayfish, which are command neurons for escape behavior. Low concentrations, or high concentrations reached gradually, are facilitatory, whereas high concentrations reached rapidly are inhibitory. The modulatory effects rapidly reverse after brief periods of application, whereas longer periods of application are followed by facilitation that persists for hours. These effects of serotonin can be reproduced by models that involve multiple interacting intracellular signaling systems that are each stimulated by serotonin. The dependence of the neuromodulatory effect on dose, rate, and duration of modulator application may be relevant to understanding the effects of natural neuromodulation on behavior and cognition and to the design of drug therapies.
Sex and grade differences in cyberbullying of Spanish students of 5th and 6th grade of Primary Education

Cyberbullying is a recent phenomenon that has a great impact on the development and well-being of children. The objective of the present study is to analyze the differences in cyberbullying (victims, bullies, and bystanders) according to the sex and grade of the participants. The sample consisted of 548 students from 5th and 6th grade of primary education. The results indicate that girls are significantly more victimized than boys, and score higher on five victimizing behaviors, seven bullying behaviors, and four behaviors of observation of cyberbullying. The students of the two courses present similar scores in being a victim, a bully, and a bystander of cyberbullying. However, 6th-graders are more victimized through manipulated videos and death threats and perform more behaviors related to blackmailing to not reveal secrets through the Internet, whereas 5th-gradersstand out due to more blackmail or threats through calls or messages. In relation to the bystanders, 5th-graders claim they observe more anonymous calls and sexual harassment. The evidence found is discussed, establishing possible directions for future studies, as well as the practical implications for the development of effective intervention programs.
Measurement of Single Top Quark Production in 7.5 fb−1 of CDF Data Using Neural Networks

We report a measurement of single top quark production in lepton plus jets final state using 7.5 fb−1 of pp̄ collision data collected by CDF Run II experiment. We select events in the W + jets topology consistent with the signature of a charged lepton (electron or muon), large missing transverse energy ( 6 ET ) from the W boson decay and two or three jets, at least one of them is required to be identified as originating from a bottom quark. We use the new POWHEG Monte Carlo generator for single top signal samples in s-channel, t-channel and Wt-channel, which are generated at NLO accuracy, with an assumed top quark mass of 172.5 GeV/c. The Neural Network multivariate method is used to discriminate signal against comparatively large backgrounds. We measure a cross section of 3.04 −0.53pb (stat+syst) and set a lower limit |Vtb| > 0.78 at the 95% confidence level, assuming mt = 172.5 GeV/c .
Spectral stability of modulated travelling waves bifurcating near essential instabilities

Localized travelling waves to reaction-diffusion systems on the real line are investigated. The issue addressed in this work is the transition to instability which arises when the essential spectrum crosses the imaginary-axis. In the first part of this work, it has been shown that large modulated pulses bifurcate near the onset of instability; they are a superposition of the primary pulse with spatially periodic Turing patterns of small amplitude. The bifurcating modulated pulses can be parametrized by the wavelength of the Turing patterns. Furthermore, they are time periodic in a moving frame. In the second part, spectral stability of the bifurcating modulated pulses is addressed. It is shown that the modulated pulses are spectrally stable if and only if the small Turing patterns are spectrally stable, that is, if their continuous spectrum only touches the imaginary-axis at zero. This requires an investigation of the period map associated with the time-periodic modulated pulses.
Effects of the temporal predictability and spatial clumping of food on the intensity of competitive aggression in the Zenaida dove

The spatial and temporal clumping of food influence an animal’s aggressiveness during competition. No studies, however, have investigated the effects of the temporal predictability of food and few studies have tested for interactions between the effects of two components of resource distribution on the rates of competitive aggression. We simultaneously manipulated the temporal predictability and the spatial clumping of food to test whether aggression increases as food becomes more predictable in time and more clumped in space. We tested these predictions using wild Zenaida doves (Zenaida aurita) in Barbados because previous work showed marked differences in social behavior between two populations, apparently related to differences in the distribution of food in space and time. There was a significant interaction between the effects of the temporal predictability and spatial clumping of food. As predicted, the rate of aggression increased as the temporal predictability of food increased, but only significantly in the spatially clumped condition. Similarly, as predicted, aggression increased as the spatial clumping of food increased, but only significantly in the temporally predictable condition. In addition, the per capita rate of aggression peaked at intermediate competitor densities in the spatially clumped condition. Differences in rates of aggression observed during experimental manipulations and between the two populations during baseline observations were generally consistent with predictions of resource defense theory. Key words: aggression, economic defendability, feeding competition, spatial clumping, temporal predictability, Zenaida aurita. [Behav Ecol 12:490–495 (2001)]
Effect of heart rate and body position on the complexity of the QRS and T wave in healthy subjects

We analysed the effect of heart rate and body position on the complexity of the QRS and T wave quantified by the ratio of 2nd/1st eigenvalue from principal component analysis (PCA) (QRS-PCA, T-PCA) using continuous 25 min 12-lead digital ECGs (500 Hz, 4.88 muV resolution) acquired on 2 occasions in supine and standing position in 15 healthy subjects (8 men, age 28.6plusmn7.5 years). In the group as a whole, QRS-PCA and T-PCA did not differ significantly between the two positions. However, the linear correlation coefficient between the PCA parameters and the RR interval varied widely between different subjects in the supine position (QRS-PCA: from 0.002 to 0.61; T-PCA: from 0.01 to 0.65) and even more in standing position (QRS-PCA: from -0.55 to 0.48; T-PCA: from -0.63 to 0.51). In both positions, the intra-subject variability of QRS-PCA and T-PCA was significantly smaller than the inter-subject variability.
On the minimal norm of a non‐regular generalized character of an arbitrary finite group

We prove that, for any generalized character θ, other than a multiple of the regular character, of any finite group G, we have ∑g∊G#|θ(g)|2 ⩾ |G|χ(1) − 1, where χ is an irreducible character of maximal degree of G and G# is the set of non‐identity elements of G. We also determine exactly when equality is achieved.
