The Millefeuille theory revisited. New theoretical lenses to understand the Millefeuille effect
Authors: Boukef Nabila , Charki Mohamed Hédi 
Published: October 2019

Les Réseaux Sociaux d’Entreprises (RSE) ont connu un récent essor et sont de plus en plus présentés comme un alternatif à l’usage de l’email. Malgré l’intérêt croissant pour ce nouveau medium, notre connaissance est encore limitée quant à l’intégration du RSE dans l’ensemble du portefeuille des moyens de communication disponibles ainsi qu’à sa capacité à remplacer l’usage de l’email. À travers notre approche enracinée et notre étude de cas réalisée dans une multinationale spécialisée dans les produits de beauté et le bien-être, nous avons mis en évidence que le RSE se superpose aux médias existants, formant ainsi un effet millefeuille. En adoptant une approche enracinée, nous avons expliqué l’effet millefeuille dans le cas spécifique du RSE vs email et proposé une version révisée de la théorie du millefeuille. Nous montrons que l’effet millefeuille résulte de la négociation des fonctionnalités matérielles du RSE ainsi que celles de l’email. Cette négociation se fait en tenant compte des normes de communication et du contexte d’utilisation des TI. Nous mettons en évidence l’intérêt d’un réel engagement des managers dans l’utilisation du RSE qui va au-delà du simple parrainage du nouveau médium. À travers cet article, nous proposons une version révisée de la théorie du millefeuille en mettant en évidence trois perspectives théoriques : il s’agit des fonctionnalités matérielles du portefeuille des médias, les normes de communication et enfin le contexte d’utilisation des TI. Nous contribuons à la littérature en SI en proposant une version révisée de la théorie du millefeuille qui intègre la perspective de l’affordance. Nous mettons ainsi en évidence que la prise en compte des fonctionnalités matérielles des médias constituant le portefeuille des moyens de communication et comment celles-ci sont appropriées par les utilisateurs, permet une meilleure compréhension de l’effet millefeuille. Notre article permet également de mettre en avant des recommandations managériales pour aider les managers à mieux faire face à la multiplication des médias disponibles et limiter ainsi les risques liés à l’effet millefeuille.
Le film de fiction comme lieu de mémoire historicisé. Du signe-monument à la trace-interstice Pour l’exemple (Joseph Losey, 1964)
Authors: Louet Sylvain 
Published: October 2019

Pour l’exemple (Losey, 1964) raconte comment l’attitude ambivalente d’un homme a été réduite à celle d’un combattant courageux alors qu’il avait été condamné pour désertion lors de la Première Guerre mondiale. Le droit et la justice, en effet, ont été utilisés par le pouvoir de Grande-Bretagne afin de faire disparaître la désertion de l’histoire nationale. Or, le passé ne passe pas : le film dévoile la relation entre la mémoire mise au ban et l’histoire racontée depuis le point de vue des vainqueurs. La fiction historiographe, en évoquant un déshérité de l’histoire dominante, met au jour les mécanismes de l’histoire officielle et orchestre des mémoires concurrentielles. Le signe-monument (de l’histoire nationale) est déchiré par la trace-interstice (de la mémoire individuelle). Évoquer la mémoire d’un homme réhabilite le groupe des fusillés de l’histoire en signalant les points aveugles de celles-ci.
El comensal de Gabriela Ybarra : le creux mémoriel comme lieu de (re)construction du passé
Authors: Billard Marion 
Published: October 2019

Le long processus de dissolution de l'organisation terroriste Euskadi Ta Askatasuna (ETA), achevé en mai 2018 met un terme à plus de cinquante années d'attentats réguliers perpétrés en Espagne et en France. Plusieurs générations ont ainsi été touchées directement ou indirectement par cette violence. On observe ces dernières années un essor des productions culturelles qui évoquent cette présence mortifère dans le but d'en conserver la mémoire. Tel est le cas du roman de Gabriela Ybarra, El comensal, publié en 2015 dans lequel elle relate l'enlèvement puis l'assassinat de son grand-père paternel, Javier de Ybarra y Bergé par l'ETA en 1977. Pour raconter cet événement qu'elle n'a pas vécu, G. Ybarra mêle des mémoires individuelles (personnelle et familiale) et collectives (journalistique, sociale et littéraire) et recourt à la fiction. L'analyse du roman d'une petite-fille d'une victime mortelle de l'ETA permettra ainsi de souligner les interactions existantes entre mémoire et post-mémoire (M. Hirsch) qui elles-mêmes déterminent les modalités de la mise en récit du passé traumatique de l'autrice et de la société espagnole.
Comparative Evaluation of Yen Angle and W Angle with ANB Angle, Wits Appraisal, and Beta Angle for Predicting Sagittal Jaw Dysplasia: A Cephalometric Study
Authors: Kapadia Romina M , Diyora Shamil D , Modi Bhumi N 
Published: October 2019

ABSTRACT
Introduction
Sagittal jaw relationship is one of the basic criteria assessed for orthodontic diagnosis. ANB angle, Wits appraisal, and Beta angle are the most commonly used measures. Yen angle and W angle have been recently introduced. It was necessary to assess their predictability by comparing them with routinely used sagittal jaw indicators.

Aim
To assess Yen angle and W angle and compare them with ANB angle, Wits appraisal, and Beta angle in predicting sagittal jaw dysplasia.

Materials and methods
A total of 40 lateral cephalograms of class I malocclusion subjects were selected and traced as per the inclusion criteria. ANB angle, Wits appraisal, Beta angle, Yen angle, and W angle were measured and compared with each other. Statistical analyses used were independent t-test, Pearson's correlation coefficient, sensitivity, specificity, and accuracy.

Results
ANB angle, Wits appraisal, Beta angle, Yen angle, and W angle all show a significant correlation with each other. Yen angle and W angle show best correlation with ANB angle showing 100% sensitivity. The values of specificity and accuracy of Yen angle with ANB angle are 73.7 and 81.48% respectively, and that of W angle with ANB angle are 44.4 and 67.74% respectively.

Conclusion
Yen angle and W angle show a good correlation with each other and with other three measures. Both the angles show highest correlation with ANB angle and the least correlation with Wits appraisal. Yen angle shows stronger correlation with ANB angle than W angle. Yen angle and W angle can be used to assess sagittal jaw dysplasia in addition to the established angles.

High-dose Accelerated vs Low-dose Frequent Regime of Iron Sucrose Therapy in Antenatal and Postnatal Women with Iron Deficiency
Authors: Anjum Shaheen , Garg Nidhi , Beriwal Sri , Parvez Anjum 
Published: October 2019

ABSTRACT

Objective
To compare an accelerated high-dose (500 mg) vs low-dose (200 mg) regimen of intravenous iron sucrose in a cohort of iron-deficient anemic antenatal patients in terms of efficacy, safety, and compliance.

Materials and methods
In a prospective hospital-based study, antenatal and postnatal women with anemia attending Jawaharlal Nehru Medical College and Hospital, Aligarh, India, between December 2010 and December 2012 were enrolled. The inclusion criteria were all outpatient and admitted anemic antenatal women ≤ 36 weeks gestation and postnatal women with hemoglobin (Hb) below 10 gm/dL, or serum ferritin ≤ 30 μg/L or transferrin saturation ≤ 40% irrespective of prior oral iron therapy. Patients were excluded from the study if they were hemodynamically unstable, actively bleeding, having fever, or were nauseated or vomiting. Participants were assigned to control and study groups according to simple random sampling. Intravenous iron sucrose group I (500 mg)/group II (200 mg) was infused after test dose on alternate days for the calculated total dose in the study population. Blood and iron indices were measured at baseline and after 2 weeks of administration of last dose. The primary outcome of the study was to assess the rise in Hb and safety of high-dose intravenous iron sucrose.

Results
There was a statistically significant increase in Hb level in patients receiving either regimen, with larger mean increase in group I (2.7 ± 0.4) compared with group II (2.25 ± 6.39). Serum iron and serum ferritin also increased in both fortnightly (p < 0.001). Blood transfusion was avoided by 90.1% in severely anemic cases with Hb < 7. Hospital stay was reduced by 50% in group I.

Conclusion
The accelerated regimen of high-dose (500 mg) intravenous iron sucrose in anemic antenatal patients appears to be safe and effective in correcting anemia, restoring iron stores, and avoiding blood transfusion.

Published: October 2019

IntroductionSleep disordered breathing (SDB) represents common comorbidities of childhood obesity leading to interrupted sleep and sleep deprivation. Sleep deprivation alters secretion of brain-derived neurotrophic factor (BDNF), which is an appetite regulator. However, little is known about the relation between BDNF and central obesity in children with SDB. The aim of the study was to evaluate BDNF level and anthropometric indices in relation to SDB in children with obesityMaterial and methodsA prospective case-control study was conducted on 30 children with obesity (BMI > 95th percentile) and 30 healthy lean children (BMI 5th-85th percentile). Polysomnographic, anthropometric data and BDNF serum level were obtained from all included children. Serum level of BDNF and anthropometric indices of obesity were assessed in relation to SDB in children with obesity. Regression analysis was done to determine predictors for SDB in children with obesity.ResultsIn comparison to healthy controls, anthropometric indices of central obesity were significantly higher while BDNF was significantly lower in obese children, especially those with SDB. Respiratory disturbance index has a significant positive correlation with anthropometric indices of central obesity and a significant negative correlation with BDNF level. Central obesity and decreased BDNF were associated with 2-fold increased risk for SDB. Waist circumference/height ratio and neck circumference/height ratio have 89.5%, 75% sensitivity and 81.23%, 84.62% specificity at a cutoff point > 0.62, > 0.24 respectively for prediction of SDB in children with obesity.ConclusionsCentral obesity and decreased BDNF represent independent predictors for SDB in children with obesity. Anthropometric indices adjusted to height are a simple screening tool for SDB in obese children.
Correlation of acute pulmonal embolism with D-dimer levels and the diameter of the pulmonary trunk in thoracic multislice computed tomography. A single-centre retrospective analysis of 100 patients
Authors: Stuppner Sigmund , Ruiu Antonio 
Published: October 2019

PurposeThe aim of this retrospective study was to evaluate the correlation between D-dimer levels in positive thrombo­embolic thoracic computed tomography (CT) with the diameter of the pulmonary trunk and to study the relation between the D-dimer and the uni- or bilateralism of the lesions and the presence of pulmonal trunk involvement. We also analysed gender-specific differences in patients with and without dilatation of the pulmonal trunk.Material and methodsA total of 100 acute care patients (50 men and 50 women) with positive thromboembolic multiple detector computed tomography of the thorax, performed on two modern CT scanners, were retrospectively studied. All thoracic CTs were evaluated by two expert radiologists, with attention paid to the diameter of the pulmonary trunk and the correlation of D-dimer level with the uni-or bilateralism of the lesions. We also analysed sex-specific correlations. All patients underwent multislice computed tomography-examination after applying 70 ml iodinated non-ionic contrast media. Graphpad Prism 8.1.1 software was used for statistical data.ResultsThe “strongest” weak correlation resulted between D-dimer levels and the axial diameter of the pulmonal trunk. Considering the correlation between the axial diameter of the pulmonal trunk and gender-related distributions, we found that female patients had higher axial diameters than men. Another weak relationship, almost zero, was found between the D-dimer level and gender. Regarding the correlation between the uni- or bilateralism of thromboembolism and the D-dimer levels, we also found a weak correlation.ConclusionsThis retrospective study showed that D-dimer levels, the diameter of the pulmonal trunk, the location, and gender-related distributions have almost no correlation and are not significantly predictive in imaging.

Abstract
We report the first demonstration of self-aligned gate (SAG) β-Ga2O3 metal-oxide-semiconductor field-effect transistors (MOSFETs) as a path toward eliminating source access resistance for low-loss power applications. The SAG process is implemented with a subtractively defined and etched refractory metal, such as Tungsten, combined with ion-implantation. We report experimental and modeled DC performance of a representative SAG device that achieved a maximum transconductance of 35 mS mm−1 and an on-resistance of ∼30 Ω mm with a 2.5 μm gate length. These results highlight the advantage of implant technology for SAG β-Ga2O3 MOSFETs enabling future power switching and RF devices with low parasitic resistance.

Published: October 2019

AbstractPulmonary perfusion with dynamic contrast‐enhanced (DCE‐) MRI is typically assessed using a single‐input tracer kinetic model. Preliminary studies based on perfusion CT are indicating that dual‐input perfusion modeling of lung tumors may be clinically valuable as lung tumors have a dual blood supply from the pulmonary and aortic system. This study aimed to investigate the feasibility of fitting dual‐input tracer kinetic models to DCE‐MRI datasets of thoracic malignancies, including malignant pleural mesothelioma (MPM) and nonsmall cell lung cancer (NSCLC), by comparing them to single‐input (pulmonary or systemic arterial input) tracer kinetic models for the voxel‐level analysis within the tumor with respect to goodness‐of‐fit statistics. Fifteen patients (five MPM, ten NSCLC) underwent DCE‐MRI prior to radiotherapy. DCE‐MRI data were analyzed using five different single‐ or dual‐input tracer kinetic models: Tofts‐Kety (TK), extended TK (ETK), two compartment exchange (2CX), adiabatic approximation to the tissue homogeneity (AATH) and distributed parameter (DP) models. The pulmonary blood flow (BF), blood volume (BV), mean transit time (MTT), permeability‐surface area product (PS), fractional interstitial volume (vI), and volume transfer constant (KTrans) were calculated for both single‐ and dual‐input models. The pulmonary arterial flow fraction (γ), pulmonary arterial blood flow (BFPA) and systemic arterial blood flow (BFA) were additionally calculated for only dual‐input models. The competing models were ranked and their Akaike weights were calculated for each voxel according to corrected Akaike information criterion (cAIC). The optimal model was chosen based on the lowest cAIC value. In both types of tumors, all five dual‐input models yielded lower cAIC values than their corresponding single‐input models. The 2CX model was the best‐fitted model and most optimal in describing tracer kinetic behavior to assess microvascular properties in both MPM and NSCLC. The dual‐input 2CX‐model‐derived BFA was the most significant parameter in differentiating adenocarcinoma from squamous cell carcinoma histology for NSCLC patients.

ObjectiveTo assess the associations of several blood immune biomarkers with the future risks of amyotrophic lateral sclerosis and Parkinson disease in a prospective cohort study with 20 years of follow‐up.MethodsThe Swedish Apolipoprotein‐Related Mortality Risk study is a longitudinal cohort study including 812,073 participants with repeated blood biomarker measurements between 1985 and 1996 and a follow‐up until 2011. Using a Cox model, we first estimated hazard ratios of amyotrophic lateral sclerosis and Parkinson disease in relation to leukocytes, immunoglobulin G, haptoglobin, and uric acid. We further described the temporal changes of these biomarkers during the 20 years prior to the diagnosis of these diseases.ResultsA total of 585 incident cases of amyotrophic lateral sclerosis and 3,769 incident cases of Parkinson disease were identified during the follow‐up. Increasing concentrations of leukocytes, haptoglobin, and uric acid were associated with a lower risk of Parkinson disease. No statistically significant association was, however, noted between the studied biomarkers and amyotrophic lateral sclerosis. Parkinson disease patients appeared to have lower levels of leukocytes and haptoglobin between 20 and 10 years before diagnosis and lower levels of uric acid during the 20 years before diagnosis, compared to controls, although statistically significant differences were only noted during parts of the respective time intervals after multivariable adjustment. No clear differences were noted between patients with amyotrophic lateral sclerosis and controls.InterpretationIf verified in studies of independent populations, our findings may suggest a different role of systemic inflammation on the risk of Parkinson disease compared to amyotrophic lateral sclerosis.

Published: October 2019

AbstractVery little is known about the realm of solid‐state metal halide compounds comprising two or more halometalate anions. Such compounds would be of great interest if their optical and electronic properties could be rationally designed. Herein, we report a new example of metal halide cluster‐assembled compound (C9NH20)9[Pb3Br11](MnBr4)2, featuring distinctly different anionic polyhedra, namely, a rare lead halide cluster [Pb3Br11]5− and [MnBr4]2−. In accordance with its multinary zero‐dimensional (0D) structure, this compound is found to contain two distinct emission centers, 565 nm and 528 nm, resulting from the formation of self‐trapped excitons and 4T1‐6A1 transition of Mn2+ ions, respectively. Based on the high durability of (C9NH20)9[Pb3Br11](MnBr4)2 upon light and heat, as well as high photoluminescence quantum yield (PLQY) of 49.8 % under 450 nm blue light excitation, white light‐emitting diodes (WLEDs) are fabricated, showcasing its potential in backlight application.

Published: October 2019

AbstractDespite its high morbidity and mortality, contrast‐induced acute kidney injury (CIAKI) remains a diagnostic dilemma because it relies on in vitro detection of insensitive late‐stage blood and urinary biomarkers. We report the synthesis of an activatable duplex reporter (ADR) for real‐time in vivo imaging of CIAKI. ADR is equipped with chemiluminescence and near‐infrared fluorescence (NIRF) signaling channels that can be activated by oxidative stress (superoxide anion, O2.−) and lysosomal damage (N‐acetyl‐β‐d‐glucosaminidase, NAG), respectively. By virtue of its high renal clearance efficiency (80 % injected doses after 24 h injection), ADR detects sequential upregulation of O2.− and NAG in the kidneys of living mice prior to a significant decrease in glomerular filtration rate (GFR) and tissue damage in the course of CIAKI. ADR outperforms the typical clinical assays and detects CIAKI at least 8 h (NIRF) and up to 16 h (chemiluminescence) earlier.

AbstractThe effect of organic ligands on the separation performance of Zr based metal–organic framework (Zr‐MOF) membranes was investigated. A series of Zr‐MOF membranes with different ligand chemistry and functionality were synthesized by an in situ solvothermal method and a coordination modulation technique. The thin supported MOF layers (ca. 1 μm) showed the crystallographic orientation and pore structure of original MOF structures. The MOF membranes show excellent selectivity towards hydrogen owing to the molecular sieving effect when the bulkier linkers were used. The molecular simulation confirmed that the constricted pore apertures of the Zr‐MOFs which were formed by the additional benzene rings lead to the decrease in the diffusivity of larger penetrants while hydrogen was not remarkably affected. The gas mixture separation factors of the MOF membranes reached to H2/CO2=26, H2/N2=13, H2/CH4=11.
