Abstract
Objectives: (1) To assess the statistical correlation between the tumor thickness (TT) by ultrasonography (USG) and microscopic measurement in cases of early oral tongue squamous cell carcinoma (OTSCC). (2) To assess the predictive capacity of TT by ultrasound in detecting nodal metastasis. Materials and Methods: Prospective analysis was performed in 24 patients for a period of 2 years from 2012 to 2013. Nodal status and TT measurement was done preoperatively by neck and intraoral USG respectively in cases of early (pT1 & T2, clinically N0) OTSCC. As per the institution protocol after histopathological confirmation of malignancy, all patients underwent resection of primary lesion and ipsilateral elective neck dissection (Level - I to IV). Measurement of TT was obtained intraoperatively from fresh glossectomy specimen and postoperatively from histopathological paraffin section examination. The statistical correlation between TT measured by USG and histopathology was assessed by Pearson’s correlation coefficient. Chi-square test was used to find the association of pathological T stage, TT with pathological nodal status. Results: Significant statistical correlation was seen between TT by USG and microscopic measures. Between the two, TT measurements were within 1 mm in 37.5% (9/24) of cases, within 2 mm in 29.16% (7/24), and was greater than 2 mm in 8 cases. The Pearson’s correlation r is 0.678 (P < 0.001) and ICC (interclass correlation coefficient) is 0.808. The average difference between microscopic and US thickness (Bias) is -0.14637 and the limits of agreement is (4.717, -4.863) with 95% limits of agreement. The rate of occult nodal metastasis was 16.6% and TT of <4 mm had no incidence of nodal metastasis. Conclusion: Ultrasonographic evaluation is reliable and cost-effective tool to measure the TT preoperatively, which will be of help in deciding the management in early OTSCC. TT of 4 mm and above was predictor of occult cervical nodal metastasis.
A simple quality control tool for assessing integrity of lead equivalent aprons
Authors: Livingstone Roshan S. , Varghese Anna 
Published: June 2018

Abstract
Background: Protective lead or lead-equivalent (Pbeq) aprons play a key role in providing necessary shielding from secondary radiation to occupational workers. Knowledge on the integrity of these shielding apparels during purchase is necessary to maintain adequate radiation safety. Aim: The aim of the study was to evaluate the lead equivalence in aprons based on simple quality assessment tool. Materials and Methods: 0.25 mm and 0.5 mm lead and lead-free aprons from 6 manufacturers were assessed using a calibrated digital X-ray unit. The percentage attenuation values of the aprons were determined at 100 kVp using an ionization chamber and the pixel intensities were analyzed using digital radiographic images of lead apron, copper step wedge tool, and 2 mm thick lead. Results: Mean radiation attenuation of 90% and 97% was achieved in 0.25 mm and 0.5 mm lead or lead-free aprons respectively. The pixel intensities from 0.25 mm Pbeq apron correspond to 0.8–1.2 mm thickness of Cu while 0.5 mm Pbeq aprons correspond to 2.0–2.8 mm of Cu. Conclusion: Pixel intensity increased with increase in the thickness of copper step wedge indicating a corresponding increase in lead equivalence in aprons. It is suggestive that aprons should be screened for its integrity from the time of purchase using computed tomography (CT), fluoroscopy, or radiography. It is recommended that this simple test tool could be used for checking lead equivalence if any variation in contrast is seen in the image during screening.

Published: June 2018

AbstractA 68-year-old male patient presented with chief complaints of chest pain and dyspnea on exertion. On physical examination, his pulse was regular at 82 bpm and blood pressure was 140/80 mmHg. Resting electrocardiography (ECG) was within normal limit and chest X-ray also did not reveal any significant abnormality. Routine blood investigations were unremarkable; transthoracic echocardiography also did not show any significant abnormality. Catheter coronary angiography revealed severe triple vessel disease and showed possibility of coronary artery fistula. Computed tomography (CT) coronary angiography showed three aberrant branches arising from right and left coronary arteries forming a sac which subsequently opened into the main pulmonary artery.
Production and transport mechanisms of NO in the polar upper mesosphere and lower thermosphere in observations and models
Authors: Hendrickx Koen , Megner Linda , Marsh Daniel R. , Smith-Johnsen Christine 
Published: June 2018

Abstract. A reservoir of nitric oxide (NO) in the lower thermosphere efficiently cools
the atmosphere after periods of enhanced geomagnetic activity. Transport from
this reservoir to the stratosphere within the winter polar vortex allows NO
to deplete ozone levels and thereby affect the middle atmospheric heat
budget. As more climate models resolve the mesosphere and lower thermosphere
(MLT) region, the need for an improved representation of NO-related processes
increases. This work presents a detailed comparison of NO in the Antarctic
MLT region between observations made by the Solar Occultation for Ice
Experiment (SOFIE) instrument on-board the Aeronomy of Ice in the Mesosphere
(AIM) satellite and simulations performed by the Whole Atmosphere Community
Climate Model with Specified Dynamics (SD-WACCM). We investigate 8 years of
SOFIE observations, covering the period 2007–2015, and focus on the Southern
Hemisphere (SH), rather than on dynamical variability in the Northern
Hemisphere (NH) or a specific geomagnetic perturbed event. The morphology of
the simulated NO is in agreement with observations though the long-term mean
is too high and the short-term variability is too low in the thermosphere.
Number densities are more similar during winter, though the altitude of peak
NO density, which reaches between 102 and 106 km in WACCM and between 98 and
104 km in SOFIE, is most separated during winter. Using multiple linear
regression (MLR) and superposed epoch analysis (SEA) methods, we investigate
how well the NO production and transport are represented in the model. The
impact of geomagnetic activity is shown to drive NO variations in the lower
thermosphere similarly across both datasets. The dynamical transport from the
lower thermosphere into the mesosphere during polar winter is found to agree
very well with a descent rate of about 2.2 km day−1 in the 80–110 km
region in both datasets. The downward-transported NO fluxes are, however, too
low in WACCM, which is likely due to medium energy electrons (MEE) and
D-region ion chemistry that are not represented in the model.
ERA-5 and ERA-Interim driven ISBA land surface model simulations: which one performs better?

Published: June 2018

Abstract. The European Centre for Medium-Range Weather Forecasts (ECMWF) recently
released the first 7-year segment of its latest atmospheric reanalysis: ERA-5
over the period 2010–2016. ERA-5 has important changes relative to the former ERA-Interim
atmospheric reanalysis including higher spatial and temporal resolutions as
well as a more recent model and data assimilation system. ERA-5 is foreseen
to replace ERA-Interim reanalysis and one of the main goals of this study is
to assess whether ERA-5 can enhance the simulation performances with respect
to ERA-Interim when it is used to force a land surface model (LSM). To that
end, both ERA-5 and ERA-Interim are used to force the ISBA (Interactions
between Soil, Biosphere, and Atmosphere) LSM fully coupled with the Total
Runoff Integrating Pathways (TRIP) scheme adapted for the CNRM (Centre
National de Recherches Météorologiques) continental hydrological
system within the SURFEX (SURFace Externalisée) modelling platform of
Météo-France. Simulations cover the 2010–2016 period at half a
degree spatial resolution. The ERA-5 impact on ISBA LSM relative to ERA-Interim is evaluated using
remote sensing and in situ observations covering a substantial part of the
land surface storage and fluxes over the continental US domain.
The remote sensing observations include (i) satellite-driven model
estimates of land evapotranspiration, (ii) upscaled ground-based observations
of gross primary production, (iii) satellite-derived estimates of surface
soil moisture and (iv) satellite-derived estimates of leaf area index (LAI).
The in situ observations cover (i) soil moisture, (ii) turbulent heat fluxes,
(iii) river discharges and (iv) snow depth. ERA-5 leads to a consistent
improvement over ERA-Interim as verified by the use of these eight
independent observations of different land status and of the model
simulations forced by ERA-5 when compared with ERA-Interim. This is
particularly evident for the land surface variables linked to the terrestrial
hydrological cycle, while variables linked to vegetation are less impacted.
Results also indicate that while precipitation provides, to a large extent,
improvements in surface fields (e.g. large improvement in the representation
of river discharge and snow depth), the other atmospheric variables play an
important role, contributing to the overall improvements. These results
highlight the importance of enhanced meteorological forcing quality provided
by the new ERA-5 reanalysis, which will pave the way for a new generation of
land-surface developments and applications.

A fase exploratória da pesquisa “Jovem e consumo midiático em tempos de convergência”, da qual participamos, nos forneceu alguns dados que desencadearam reflexões sobre os sentidos emergentes da trajetória dos jovens paulistanos na rede social Facebook. Neste texto, especificamente, nos atemos aos dados dos perfis e aos supertemas recorrentes nos posts dos jovens observados para inferir sobre usos e consumos midiáticos nesta rede social e, inclusive, como o Facebook participa na manutenção ou na transformação das culturas na lógica das sociedades midiatizadas.
Katalánská kartografická díla 14. a 15. století a zachycení Asie a Afriky
Authors: Liščák Vladimír 
Published: June 2018

Švýcarské nakladatelství Urs Graf Verlag GmbH se sídlem v Dietikonu na předměstí Curychu vydalo v letech 1977 a 1995 faksimile dvou výjimečných katalánských kartografických děl 14. a 15. století. Prvním z nich byla Mappa mundi, jež vznikla mezi lety 1375 a 1381), druhým kruhová Mappa mundi Estense z období mezi 1450 a 1460. První dílo je označováno též jako Katalánský atlas 1375 a skládá se z několika tabulí zachycujících tehdy známý svět od pobřeží Atlantského oceánu až po východní pobřeží Asie. Hlavními prameny pro zpracování východní části Asie byly cestopisy Marka Pola, tzv. Jana Mandevila a Odorika z Pordenone. (Grosjean, ed., 1977) Druhým dílem je kruhová mapa o průměru 113 cm, zachycující kromě známého světa i země dosud neobjevené, ale předpokládané, s jejich přibližnou polohou. (Milano, ed., 1995) Obě díla jsou bohatě ilustrována a na své si přijdou i milovníci vlajek. Faksimile, reprodukující díla ve skutečné velikosti, doplňují podrobné studie a přepisy katalánských textů na mapách s jejich komentovanými překlady (v prvním případě do němčiny, ve druhém do italštiny a němčiny). Tento příspěvek podává přehled o obou těchto mapách s originálními texty a jejich překlady na základě nejnovější literatury.
Fotografía, propaganda y educación. Presentación
Authors: Comas Rubi Francesca , Pozo Andrés María del Mar 
Published: June 2018

Desde sus orígenes, la fotografía se ha considerado un testimonio visual objetivo de un hecho o momento del pasado, y se ha utilizado como tal para ilustrar o reforzar el texto escrito. Durante muchas décadas, la tendencia general ha conducido a pensar que la fotografía refleja algo real y objetivo. Y es cierto que contiene elementos, objetos, espacios o personas cuya existencia queda verificada gracias a la imagen. La fotografía puede mentir sobre el sentido de una cosa, pero no sobre su existencia. Hay, por tanto, elementos preexistentes en cualquier fotografía, que nos aportan información objetiva sobre su presencia en el pasado. Pero detrás de una fotografía hay muchos más elementos personales, institucionales o sociales que la han condicionado. Forma parte de un contexto social, histórico, político y cultural, que afecta tanto a su producción como a su difusión. No todo se fotografía ni en todo momento. Al igual que cualquier producto social, como bien apuntaba Bourdieu, lo que se considera en un momento dado fotografiable es fruto de un consenso al que se llega a partir de intereses, voluntades e incluso patrones sociales preestablecidos. El análisis de una fotografía, por tanto, deberá ir más allá de constatar la existencia histórica de los elementos que aparecen en ella, para adentrarse, teniendo en cuenta su contexto en sentido amplio, en aquello que representa, en el discurso que construye a través de la imagen.
Reconceptualising workplace resilience - A cross-disciplinary perspective.

Published: June 2018

<p>Stressful situations, performance pressure, and setbacks are part of contemporary organizational life. The dynamic nature of technological advances and globalisation of business leads to tougher competitive pressures and constant change. People’s responses to these challenging circumstances vary widely. Some bounce back and adapt to increasing challenges and adversity, others’ healthy functioning is significantly impaired. Even though resilience is recognised as a crucial issue in the workplace, the rates of new cases of work-related stress and depression have remained broadly flat for more than 10 years. Resilience research within Applied Psychology typically focuses on the psychological domain of a person’s functioning. This means that also resilience trainings or interventions focus on only one area. The present paper aims to build a comprehensive conceptualization of workplace resilience ultimately to assist in informing targeted intervention and in developing a model to move the research area forward as a whole. A cross-disciplinary understanding of and approach to individual resilience in the workplace would allow to better understand the mechanism of why some people bounce back from adverse events whereas others’ well-being declines. We propose a resilience framework with antecedents considering psychological (cognitive and emotional) and physiological correlates (cardiovascular, gastrointestinal and metabolic). </p>
Stratégies d’engagement, faisabilité et impact potentiel d’une intervention de groupe cognitive comportementale pour la psychose au sein d’une équipe de suivi intensif dans le milieu
Authors: Francoeur Audrey , Hache-Labelle Catherine , Samson Crystal , Vézina Martin , Lecomte Tania 
Published: June 2018

Objectifs Le but de cette étude pilote est de documenter les stratégies utilisées pour faciliter l’engagement des participants d’une équipe de suivi intensif dans le milieu (SIM) à une thérapie cognitive comportementale pour la psychose (TCCp) de groupe offerte pour la première fois dans ce contexte, ainsi que de décrire la faisabilité de cette intervention auprès de ce type de clientèle et des intervenants impliqués.
Méthode Une TCCp de groupe de 24 rencontres a été mise en place. Les participants ont été recrutés parmi les deux équipes SIM de Laval. Différentes stratégies ont été élaborées et documentées afin de favoriser l’engagement à la thérapie des participants. Les participants ont rempli les questionnaires suivants : l’Échelle brève d’estime de soi ; l’Inventaire bref des symptômes psychiatriques ; l’Échelle de provisions sociales avant et après la thérapie.
Résultats Les données descriptives montrent que les stratégies faisant partie de la catégorie « Renforcements positifs » ont été les plus utilisées, étant suivies de près par les « Matériels et services » et ensuite par les stratégies visant à pallier les « Problèmes de mémoire ». Les participants se sont présentés en moyenne à 76 % des séances. Quatre participants sur huit ont eu une amélioration sur leur score global d’estime de soi, 3 se sont améliorés sur leur soutien social et 3 se sont améliorés au niveau de l’indice de sévérité globale des symptômes.
Conclusion L’information recueillie pourrait être très importante pour d’autres équipes de suivi intensif qui souhaiteraient effectuer une TCCp au sein de la clientèle ciblée. Celle-ci pourrait particulièrement en bénéficier en considérant qu’une TCCp de groupe pourrait diminuer l’isolement social et la marginalisation souvent vécus par les individus ayant des troubles mentaux graves.
Multiple processing limitations underlie multitasking costs
Authors: Lui Kelvin F. H. , Wong Alan C.-N. 
Published: June 2018

Background. Human multitasking is typically defined as the practice of performing more than one task at the same time (dual-task) or rapidly alternating between multiple tasks (task switching). The majority of research in multitasking has been focusing on individual paradigms, with surprisingly little effort in understanding their relationships.
Methods. We adopted an individual-differences approach to reveal the limitations underlying multitasking costs measured in different paradigms.
Results. Exploratory factor analyses revealed not a general multitasking factor but instead three different processing limitations associated with response selection, retrieval and maintenance of task information, and task-set reconfiguration. The three factors were only weakly correlated with and thus not reducible to common measures of processing speed, working memory capacity and fluid intelligence. Males and females excelled in different aspects of multitasking, demonstrating the benefit of using a multifaceted view of multitasking competency in group comparison.
Discussion. Findings of the current study help resolve conflicting results between studies using different paradigms, and form the basis of more comprehensive measurement tools and training protocols covering different aspects of multitasking limitations. The study will also help future integration of multitasking abilities into the theoretical framework of executive function.
Bistable and Reconfigurable Photonic Crystals—Electroactive Shape Memory Polymer Nanocomposite for Ink‐Free Rewritable Paper
Authors: Xie Yu , Meng Yuan , Wang Wenxin , Zhang Elric , Leng Jinsong , Pei Qibing 
Published: June 2018

AbstractPaper has remained the world's most‐widely accessible information medium even as sustainable and reusable paper replacements have attracted increasing attention. Here, an ink‐free rewritable paper concept is developed that combines recent developments in photonic crystals, shape memory polymers, and electroactive polymers in a nanocomposite that matches the benefits of paper as a zero‐energy, long‐term data storage medium, but provides the additional advantage of rewritability. The rewritable paper consists of a ferroferric oxide‐carbon (Fe3O4@C) core–shell nanoparticle (NP)‐based photonic crystal embedded in a bistable electroactive polymer (BSEP). Electrical actuation induces large deformation in the z‐axis of the nanocomposite, creating distinct color change in the actuated area. This nanocomposite stores high fidelity color images without inks, the images remain stable after more than a year of storage in ambient conditions, and the stored images can then be rewritten over 500 times without degrading. A seven‐segment numerical display is also demonstrated.
Probing Quantum Confinement and Electronic Structure at Polar Oxide Interfaces

Published: June 2018

AbstractPolar discontinuities occurring at interfaces between two materials constitute both a challenge and an opportunity in the study and application of a variety of devices. In order to cure the large electric field occurring in such structures, a reconfiguration of the charge landscape sets in at the interface via chemical modifications, adsorbates, or charge transfer. In the latter case, one may expect a local electronic doping of one material: one example is the two‐dimensional electron liquid (2DEL) appearing in SrTiO3 once covered by a polar LaAlO3 layer. Here, it is shown that tuning the formal polarization of a (La,Al)1−x(Sr,Ti)xO3 (LASTO:x) overlayer modifies the quantum confinement of the 2DEL in SrTiO3 and its electronic band structure. The analysis of the behavior in magnetic field of superconducting field‐effect devices reveals, in agreement with ab initio calculations and self‐consistent Poisson–Schrödinger modeling, that quantum confinement and energy splitting between electronic bands of different symmetries strongly depend on the interface total charge densities. These results strongly support the polar discontinuity mechanisms with a full charge transfer to explain the origin of the 2DEL at the celebrated LaAlO3/SrTiO3 interface and demonstrate an effective tool for tailoring the electronic structure at oxide interfaces.

Published: June 2018

AbstractBased on bottom‐up assembly of highly variable neural cells units, the nervous system can reach unequalled level of performances with respect to standard materials and devices used in microelectronic. Reproducing these basic concepts in hardware could potentially revolutionize materials and device engineering which are used for information processing. Here, an innovative approach that relies on both iono‐electronic materials and intrinsic device physics to show pattern classification out of a 12‐unit biosensing array is presented. The reservoir computing and learning concept to demonstrate relevant computing based on the ionic dynamics in 400 nm channel‐length organic electrochemical transistor is used. It is shown that this approach copes efficiently with the high level of variability obtained by bottom‐up fabrication using a new electropolymerizable polymer, which enables iono‐electronic device functionality and material stability in the electrolyte. The effect of the array size and variability on the performances for a real‐time classification task paving the way to new embedded sensing and processing approaches is investigated.
