La gestion du risque engendré par le recul d'une falaise en zone urbanisée : l'exemple du quartier des Minimes à La Rochelle (Charente-Maritime, France) dans les années 1970-80
Authors: Albinet Vincent 
Published: January 2018

L'aménagement urbain, planifié, de la péninsule des Minimes en périphérie de La Rochelle au cours des années 1970-1980 a rendu nécessaire le contrôle du recul de la petite falaise calcaire (5 à 8 mètres de hauteur) qui entoure la péninsule. A cet effet, une digue en enrochements longue de plusieurs centaines de mètres fut érigée à son pied en 1981-1982. Le choix, consécutif au changement de majorité municipale en 1971, de reculer de plusieurs dizaines de mètres les constructions, initialement prévues jusqu'au bord de la falaise, avait pourtant créé les conditions requises pour mettre en oeuvre une stratégie mieux adaptée au site : accepter l'érosion de la falaise, la laisser se poursuivre et intégrer la perte de terres dans les plans d'aménagement du quartier.
Cette perte était tolérable en raison de l'extrême lenteur avec laquelle recule la falaise, 6 à 10 cm par an en moyenne au cours des deux derniers siècles. C'est ce que révèlent les mesures faites avec le logiciel Erdas-Imagine après superposition des plans cadastraux napoléonien et actuel. La décision d'implanter en retrait les constructions garantissait, à un tel rythme, leur sécurité pour une longue durée (plusieurs siècles). Motivée par le souci de préserver le site et l'accès public au rivage, elle inscrivait dans les faits une efficace prévention contre le risque engendré par l'érosion de la falaise.
Que ceci ne fut pas perçu par les protagonistes, au point de recourir à des travaux de génie civil pour fixer la ligne de rivage, souligne l'inertie du système d'action humain construit pour faire face à l'érosion de la côte qui longtemps a enfermé acteurs et actions dans des pratiques convenues tout entières tournées vers la «défense contre la mer». La transformation enclenchée de ce système constitue aujourd'hui l'enjeu majeur. D'elle viendra (a commencé de venir) le renouvellement des pratiques de gestion du recul des falaises et de la côte toute entière.
To the Galactic Virial Radius with Hyper Suprime-Cam

Published: January 2018

Abstract
We exploit the exquisite, deep Hyper Suprime-Cam (HSC) imaging data to probe the Galactic halo out to 200 kpc. Using the ∼100 square degree, multiband photometry of the first HSC Wide survey data release, we identify blue horizontal branch (BHB) stars beyond 50 kpc in the halo. The presence of the Sagittarius (Sgr) stream in the HSC fields produces a notable excess of stars at the apocenter of the leading arm (∼50–60 kpc). For fields excluding Sgr, the BHB counts are consistent with a continuation of a −4 power law from the inner halo. However, we find that the majority of the non-Sgr BHB stars beyond 50 kpc reside in one 27 square degree HSC field called “VVDS.” Curiously, this field is located close to the Magellanic plane, and we hypothesize that the excess of stars between 50 and 200 kpc could be associated with distant Magellanic debris. Indeed, without the VVDS, there are very few BHBs in the remaining portions of the Galaxy probed by the HSC. Accordingly, this scarcity of tracers is consistent with a significant decline in stellar density beyond 50 kpc, with a power law of −4 or steeper.

Published: January 2018

Abstract
In a low-density region of the Shapley supercluster we identified an interacting galaxy pair at redshift z = 0.04865 in which the Seyfert 2 nucleus of the main galaxy (ShaSS 073) is exciting an extended emission line region (EELR, ∼170 kpc2) in the disk of the less massive companion (ShaSS 622). New integral-field spectroscopy and the multiband data set, spanning from far-ultraviolet to far-infrared and radio wavelengths, allowed us to obtain a detailed description of the ShaSS 622–073 system. The gas kinematics shows hints of interaction, although the overall velocity field shows a quite regular rotation in both galaxies, thus suggesting that we are observing their first encounter as confirmed by the estimated distance of 21 kpc between the two galaxy centers. The detected

active galactic nucleus (AGN) outflow and the geometry of the EELR in ShaSS 622 support the presence of a hollow bicone structure. The status and sources of the ionization across the whole system have been analyzed through photoionization models and a Bayesian approach that prove a clear connection between the AGN and the EELR. The luminosity of the AGN (

erg s−1) is a factor of 20 lower than the power needed to excite the gas in the EELR (4.6 × 1045 erg s−1), indicating a dramatic fading of the AGN in the past 3 × 104 yr. ShaSS 073–622 provides all the ingredients listed in the recipe of a light echo where a highly-ionized region maintains memory of a preceding more energetic phase of a now-faded AGN. This is the first case of a light echo observed between two galaxies.
Unlocking Sensitivity for Visibility-based Estimators of the 21 cm Reionization Power Spectrum

Published: January 2018

Abstract
Radio interferometers designed to measure the cosmological 21 cm power spectrum require high sensitivity. Several modern low-frequency interferometers feature drift-scan antennas placed on a regular grid to maximize the number of instantaneously coherent (redundant) measurements. However, even for such maximum-redundancy arrays, significant sensitivity comes through partial coherence between baselines. Current visibility-based power-spectrum pipelines, though shown to ease control of systematics, lack the ability to make use of this partial redundancy. We introduce a method to leverage partial redundancy in such power-spectrum pipelines for drift-scan arrays. Our method cross-multiplies baseline pairs at a time lag and quantifies the sensitivity contributions of each pair of baselines. Using the configurations and beams of the 128-element Donald C. Backer Precision Array for Probing the Epoch of Reionization (PAPER-128) and staged deployments of the Hydrogen Epoch of Reionization Array, we illustrate how our method applies to different arrays and predict the sensitivity improvements associated with pairing partially coherent baselines. As the number of antennas increases, we find partial redundancy to be of increasing importance in unlocking the full sensitivity of upcoming arrays.

Objetivo: Avaliar a influência da manipulação de uma resina composta (RC) com diferentes luvas na sua resistência adesiva à dentina. Metodologia: 25 terceiros molares hígidos foram seccionados 2 mm abaixo do sulco central, expondo a dentina (D). A D foi condicionada com ácido fosfórico 35%, lavada, e o sistema adesivo Single Bond Universal (3M ESPE) foi aplicado. Os dentes foram distribuídos aleatoriamente em 5 grupos, de acordo com o tipo da manipulação da RC: C (controle)- RC inserida diretamente do tubo para a D; LL- RC manipulada com luvas de látex antes da inserção; LV- RC manipulada com luvas de vinil; LC- RC manipulada com luvas de látex contaminadas; VC- RC manipulada com luvas de vinil contaminadas. Após, o conjunto foi seccionado em uma máquina de corte para a obtenção dos palitos com área aproximada de 1 mm², que foram armazenados em água destilada a 37°C por 6 meses. O teste foi realizado em uma máquina de ensaio (EMIC), com velocidade de 0,5 mm/min. Os valores de resistência adesiva foram calculados (MPa) e comparados com ANOVA, Tukey (α=0,05) e Weibull. Resultados: O grupo com maior resistência adesiva foi o LV (38,74 ± 3,63 MPa), estat
Método: Foi aplicado questionário a 164 docentes do ensino fundamental do Município de Almirante Tamandaré/PR, do período vespertino, para avaliação do nível de conhecimento sobre as atitudes no pronto-atendimento a crianças em caso de TAD. Os professores responderam ao QTDA (Questionário sobre o pronto atendimento ao traumatismo alvéolo dentário), que continham 10 (dez) perguntas de múltipla escolha. O questionário contém questões sobre a atitude a ser tomada em caso de traumatismo na dentição decídua (n = 5) e na dentição permanente (n = 5), sendo estas referentes a situações de avulsão, intrusão, extrusão e fratura dentária. Cada pergunta continha de 4 a 5 opções de resposta, sendo possível, ao respondente, descrever outra atitude, caso não considerasse nenhuma das alternativas como correta. O QTDA foi respondido em dois momentos, um anterior a leitura de folheto educativo (QTDA1) e outro posterior a sua leitura (QTDA2).
Resultado: Observou-se que 43,20% dos docentes não tinham conhecimento sobre os procedimentos corretos a serem adotados numa situação de TAD. Após a leitura do panfleto educativo, a taxa de acerto aumentou cerca de 21,83%, ou seja, houve diferença estatisticamente significante (p≤0,001) entre os escores antes e depois da leitura do panfleto, o que reflete uma melhora no nível de conhecimento por parte dos respondentes.
Conclusão: O folheto educativo mostrou-se eficiente na aquisição de conhecimento sobre o tema TAD, resultando num percentual significativamente positivo após a leitura do folheto educativo, sendo método barato e, os educadores fazem a leitura onde e quando achar conveniente.

Breast Specimen Processing and Reporting With an Emphasis on Margin Evaluation: A College of American Pathologists Survey of 866 Laboratories
Authors: Guidi Anthony J. , Tworek Joseph A. , Mais Daniel D. , Souers Rhona J. , Blond Barbara J. , Brown Richard W. 
Published: January 2018

Context.—The College of American Pathologists (CAP) developed protocols for reporting pathologic characteristics of breast cancer specimens, including margin status. The Society of Surgical Oncology (SSO) and the American Society for Radiation Oncology (ASTRO) published treatment guidelines regarding margins in patients with invasive cancer; and SSO, ASTRO, and the American Society of Clinical Oncology (ASCO) recently published guidelines for patients with ductal carcinoma in situ.Objective.—To assess current practices among pathologists with regard to the processing/reporting of breast specimens, assess compliance with CAP cancer protocols, and assess alignment with SSO/ASTRO and SSO/ASTRO/ASCO guidelines.Design.—A survey concerning breast specimen processing/reporting was distributed to pathologists enrolled in the CAP Performance Improvement Program in Surgical Pathology.Results.—Ninety-four percent (716 of 764 respondents) and 91% (699 of 769 respondents) define positive margins as “tumor on ink” for invasive cancer and ductal carcinoma in situ, respectively, in compliance with CAP cancer protocols and with SSO/ASTRO and SSO/ASTRO/ASCO guidelines. Of 791 respondents who provided details regarding methods for margin evaluation, 608 (77%) exclusively examine perpendicular margins, facilitating guideline compliance. However, 183 of 791 respondents (23%) examine en face margins in at least a subset of specimens, which may preclude guideline compliance in some cases. When separate cavity (shave) margins are examined, while 517 of 586 respondents (88%) ink these specimens, 69 of 586 (12%) do not, and this may also preclude guideline compliance in some cases.Conclusions.—A substantial proportion of survey participants report margin status for breast cancer specimens in a manner consistent with CAP cancer protocols, and in alignment with SSO/ASTRO and SSO/ASTRO/ASCO guidelines. However, there are opportunities for some laboratories to modify procedures in order to facilitate more complete adherence to guidelines.
Genotoxic evaluation of Mexican welders occupationally exposed to welding-fumes using the micronucleus test on exfoliated oral mucosa cells: a cross-sectional, case-control study
Authors: Jara-Ettinger Ana C. , López Tavera Juan C. , Zavala-Cerna Guadalupe , Torres-Bugarín Olivia 
Published: January 2018

Background: An estimated of 800,000 people worldwide are occupationally exposed to welding-fumes. Previous studies show that the exposure to such fumes is associated with damage to genetic material and increased cancer risk. In this study, we evaluate the genotoxic effect of welding-fumes using the Micronucleus Test on oral mucosa cells of Mexican welders.
Material and Methods: We conducted a cross-sectional, matched case-control study of n = 39 (20 exposed welders, and 19 healthy controls). Buccal mucosa smears were collected and stained with acridine orange, observed under 100x optical amplification with a fluorescence lamp, and a single-blinded observer counted the number of micronuclei and other nuclear abnormalities per 2000 observed cells. We compared the frequencies of micronuclei and other nuclear abnormalities, and fitted generalised linear models to investigate the interactions between nuclear abnormalities and the exposure to welding-fumes, while controlling for smoking and age.
Results: Binucleated cells and condensed-chromatin cells showed statistically significant differences between cases and controls. The frequency of micronuclei and the rest of nuclear abnormalities (lobed-nuclei, pyknosis, karyolysis, and karyorrhexis) did not differ significantly between the groups. After adjusting for smoking and age, the regression results showed that the occurrence of binucleated cells could be predicted by the exposure to welding-fumes plus the age and tobacco consumption; for the condensed-chromatin cells, our model showed that the exposure to welding-fumes is the only reliable predictor.
Conclusions: Our findings suggest that Mexican welders who are occupationally exposed to welding-fumes have increased counts of binucleated and condensed-chromatin cells. Nevertheless, the frequencies of micronuclei and the rest of nuclear abnormalities did not differ between cases and controls. Further studies, with bigger sample sizes and less variability, could shed more light on this subject.
The relationships between exercise and affective states: a naturalistic, longitudinal study of recreational runners
Authors: Bonham Tim , Pepper Gillian V. , Nettle Daniel 
Published: January 2018

Background
Although people generally feel more positive and more energetic in the aftermath of exercise than before, longitudinal research on how exercise relates to within-person fluctuations in affect over the course of everyday life is still relatively limited. One constraint on doing such research is the need to provide participants with accelerometers to objectively record their exercise, and pagers to capture affective reports.

Aims
We aimed to develop a methodology for studying affect and exercise using only technology that participants already possess, namely GPS running watches and smartphones. Using this methodology, we aimed to characterize within-individual fluctuations in affective valence and arousal in relation to bouts of exercise, and explore possible moderators of these fluctuations.

Methods
We recruited a sample of 38 recreational runners. Participants provided daily affective reports for six weeks using their smartphones. Information on their runs was harvested from their own GPS devices via an online platform for athletes.

Results
Average valence and arousal were higher on days when the person had run than on the next day, and higher the day after a run than on the days after that. Over the course of the day of a run, valence and arousal declined significantly as the time since the run increased. Physically fitter participants had more positive valence overall, and this was particularly true when they had not run recently. There was some evidence of higher-dose (i.e., longer and faster) runs being associated with lower arousal on the next and subsequent days. Gender did not moderate associations between running and valence or arousal.

Discussion
Our study demonstrated the potential for studying the associations between affect and exercise in a way that is precise, undemanding for participants, and convenient for researchers, using technologies that participants already own and use.

ImportanceAlthough trial data support the omission of axillary surgery and radiation therapy (RT) in women aged 70 years or older with T1N0 hormone receptor–positive (HR+) breast cancer, potential overtreatment in older adults with frailty persists.ObjectiveTo determine how much geospatial variation in locoregional therapy may be attributed to region vs patient factors.Design, Setting, and ParticipantsThis retrospective cross-sectional study included women aged 70 years or older who were diagnosed with HR+/ERBB2-negative (ERBB2−) breast cancer from January 1, 2013, to December 31, 2017. Data came from Surveillance, Epidemiology, and End Results–Medicare. Hierarchical multivariable modeling was used to evaluate the variance in deescalated care attributable to 4 domains, ie, (1) random, (2) region (health service area [HSA]), (3) patient factors, and (4) unexplained. Patient factors included age, frailty (validated claims-based measure), Charlson Comorbidity Index (CCI), and socioeconomic status (Yost index). Analyses were performed from January to October 2023.ExposureHSA.Main Outcomes and MeasuresDeescalated care, defined as omission of axillary surgery, RT, or both. Standard therapy was defined as lumpectomy, axillary surgery, and RT or mastectomy with axillary surgery. Multivariable logistic regression was used to identify factors associated with deescalated care receipt.ResultsOf 9173 patients (mean [SD] age, 76.5 [5.2] years), 2363 (25.8%) were aged 80 years or older, 705 (7.7%) had frailty, and 419 (4.6%) had a CCI of 2 or greater. While 4499 (49.1%) underwent standard therapy, 4674 (50.9%) underwent deescalated therapy (1193 [13.0%] of the population omitted axillary surgery and 4342 [55.5%] of patients undergoing lumpectomy omitted RT). Of the total variance, random variation explained 27.3%, region/HSA explained 35.3%, patient factors explained 2.8%, and 34.5% was unexplained. In adjusted models, frailty and increased age were associated with a higher likelihood of undergoing deescalated therapy (frailty: odds ratio [OR], 1.70; 95% CI, 1.43-2.02; age, by 1-year increment: OR, 1.10; 95% CI, 1.09-1.11), but CCI was not. Patients in rural areas compared with those in urban areas (OR, 0.82; 95% CI, 0.68-0.99) and Asian and Pacific Islander patients compared with non-Hispanic White patients (OR, 0.68; 95% CI, 0.54-0.85) had a lower likelihood of undergoing deescalated therapy.Conclusions and RelevanceIn this retrospective cross-sectional study of women aged 70 years or older diagnosed with T1N0 HR+/ERBB2− breast cancer, region/HSA contributed more to the variation in deescalated therapy use than patient factors. Unexplained variation may be attributed to unmeasured characteristics, such as multidisciplinary environment and patient preference. Decision support efforts to address overtreatment should target regions with low rates of evidence-based deescalation.

AbstractObjectiveParamagnetic rim lesions (PRLs) are a biomarker of chronic active lesions (CALs), and an important driver of neurological disability in multiple sclerosis (MS). The reason subtending some acute lesions evolvement into CALs is not known. Here we ask whether a relatively lower oxygen content is linked to CALs.MethodsIn this prospective cross‐sectional study, 64 people with multiple sclerosis (PwMS), clinically isolated syndrome and radiologically isolated syndrome underwent a 7.0 Tesla (7 T) brain magnetic resonance imaging (MRI). The scanning protocol included a T2‐w fluid‐attenuated inversion recovery (FLAIR), and a single echo gradient echo from which susceptibility‐weighted imaging (SWI) was derived. WM lesions were identified on the T2‐w‐FLAIR whilst PRLs were identified on the SWI sequence. T2‐lesions were classified as PRLs and rimless lesions (PRLs‐). We registered a universal vascular atlas to each subject's T2‐w‐FLAIR and classified each T2‐lesions according to its location into watershed‐ (ws), non‐watershed‐ (nws), and mixed‐lesion (m). Ws‐lesions were defined as lesions that were fully located in a region between the territories of two major arteries.ResultsOut of 1,975 T2‐lesions, 88 (4.5%) were PRLs. Ws‐regions had a higher number (p = 0.005) and proportion (p < 0.001) of PRLs‐ compared to nws‐regions. Ws‐PRL‐ were larger compared to nws‐ones (p = 0.009). The number (p = 0.043) and proportion (p < 0.001) of PRLs was higher in ws‐regions compared to nws‐ones. Ws‐PRLs were not significantly larger than nws‐ones (p = 0.195).InterpretationWe propose the novel concept of a link between arterial vascularization and chronic activity in MS by demonstrating a preferential localization of CALs in ws‐territories.
