Published: May 2018

La période qui va du milieu du xe siècle au milieu du xive siècle connaît, en Europe, un essor qui se marque dans tous les secteurs d’activité. Pour répondre aux besoins nouveaux, les minerais sont activement recherchés. L’argent, nécessaire au monnayage, occupe la première place. Le district minier qui s’est développé en bordure du Chassezac offre l’opportunité d’étudier un ensemble de chantiers extractifs conservés dans leur état médiéval (xie-xiiie siècle), associés à un véritable « quartier industriel » concentrant les ateliers dévolus au traitement du minerai. Cet ensemble n’est pas isolé et permet une mise en perspective sur la place et le rôle des mines de métaux précieux dans la formation des territoires et leur encadrement politique dans le sud de la France.
L’Historical archaeology et l’archéologie médiévale et moderne en France
Authors: Chapelot Jean 
Published: May 2018

L’autobiographie publiée par Ivor Noël Hume1 est une histoire de l’archéologie dans le Royaume-Uni et en Amérique du Nord. Né en 1927 à Londres, l’auteur a commencé sa carrière après la guerre en fouillant des sites post-médiévaux dans les ruines de la capitale détruite par les bombardements allemands. En 1956, il part aux États-Unis et va, à partir des fouilles qu’il dirige à Williamsburg (Virginie) et par le biais de ses très nombreuses publications, devenir l’un des pères fondateurs de l’archéologie des xvie-xviiie siècles, officiellement constituée en 1968 avec la création de la Society for Historical Archaeology. L’historical archaeology, qui à l’origine était l’étude des vestiges archéologiques postérieurs à 1492 en Amérique du Nord, est devenue à partir des années 1970-1980 une méthode de recherche puis un mode d’étude du monde moderne par la combinaison d’une documentation variée qui inclut les artefacts, les éléments bâtis, les objets d’art, les sources écrites, etc. La réflexion développée par les spécialistes de l’historical archaeology sur leur activité, notamment l’emploi conjoint de sources documentaires variées, concerne tous les archéologues qui travaillent sur des sociétés historiques, notamment les médiévistes européens. Les principaux résultats sont présentés dans la seconde partie de l’article2.

Published: May 2018

Abstract
Naive T cells are thought to be functionally quiescent. In this study, we studied and compared the phenotype, cytokine profile, and potential function of human naive CD4+ T cells in umbilical cord and peripheral blood. We found that naive CD4+ T cells, but not memory T cells, expressed high levels of chemokine CXCL8. CXCL8+ naive T cells were preferentially enriched CD31+ T cells and did not express T cell activation markers or typical Th effector cytokines, including IFN-γ, IL-4, IL-17, and IL-22. In addition, upon activation, naive T cells retained high levels of CXCL8 expression. Furthermore, we showed that naive T cell–derived CXCL8 mediated neutrophil migration in the in vitro migration assay, supported tumor sphere formation, and promoted tumor growth in an in vivo human xenograft model. Thus, human naive T cells are phenotypically and functionally heterogeneous and can carry out active functions in immune responses.
The Bern Simple Climate Model (BernSCM) v1.0: an extensible and fully documented open-source re-implementation of the Bern reduced-form model for global carbon cycle–climate simulations
Authors: Strassmann Kuno M. , Joos Fortunat 
Published: May 2018

Abstract. The Bern Simple Climate Model (BernSCM) is a free open-source
re-implementation of a reduced-form carbon cycle–climate model which
has been used widely in previous scientific work and IPCC assessments.
BernSCM represents the carbon cycle and climate system with a small
set of equations for the heat and carbon budget, the parametrization
of major nonlinearities, and the substitution of complex component
systems with impulse response functions (IRFs). The IRF approach
allows cost-efficient yet accurate substitution of detailed parent
models of climate system components with near-linear behavior.
Illustrative simulations of scenarios from previous multimodel
studies show that BernSCM is broadly representative of the range of
the climate–carbon cycle response simulated by more complex and
detailed models. Model code (in Fortran) was written from scratch
with transparency and extensibility in mind, and is provided open
source. BernSCM makes scientifically sound carbon cycle–climate
modeling available for many applications. Supporting up to decadal
time steps with high accuracy, it is suitable for studies with high
computational load and for coupling with integrated assessment
models (IAMs), for example. Further applications include climate risk assessment in
a business, public, or educational context and the estimation of
CO2 and climate benefits of emission mitigation options.
Seasonal variations of the backscattering coefficient measured by radar altimeters over the Antarctic Ice Sheet
Authors: Adodo Fifi Ibrahime , Remy Frédérique , Picard Ghislain 
Published: May 2018

Abstract. Spaceborne radar altimeters are a valuable tool for observing the Antarctic
Ice Sheet. The radar wave interaction with the snow provides information on both
the surface and the subsurface of the snowpack due to its dependence on
the snow properties. However, the penetration of the radar wave within the
snowpack also induces a negative bias on the estimated surface elevation.
Empirical corrections of this space- and time-varying bias are usually based
on the backscattering coefficient variability. We investigate the spatial and
seasonal variations of the backscattering coefficient at the S (3.2 GHz ∼ 9.4 cm),
Ku (13.6 GHz ∼ 2.3 cm) and Ka (37 GHz ∼ 0.8 cm) bands. We identified that the backscattering
coefficient at Ku band reaches a maximum in winter in part of the continent
(Region 1) and in the summer in the remaining (Region 2), while the evolution
at other frequencies is relatively uniform over the whole continent. To
explain this contrasting behavior between frequencies and between regions, we
studied the sensitivity of the backscattering coefficient at three
frequencies to several parameters (surface snow density, snow temperature and
snow grain size) using an electromagnetic model. The results show that the
seasonal cycle of the backscattering coefficient at Ka frequency is
dominated by the volume echo and is mainly driven by snow temperature
evolution everywhere. In contrast, at S band, the cycle is dominated by the
surface echo. At Ku band, the seasonal cycle is dominated by the volume echo
in Region 1 and by the surface echo in Region 2. This investigation provides
new information on the seasonal dynamics of the Antarctic Ice Sheet surface
and provides new clues to build more accurate corrections of the radar
altimeter surface elevation signal in the future.

Banishment from semi-public places. Exclusion orders from a legal perspective
The semi-public domain covers the places that are accessible to the public but which are controlled by private entities. Shopping malls, public transport, bars and sports events are examples of such places. In case of misconduct, the private manager may impose exclusion orders. This sanction relies on legal contracts and the exclusive nature of the right to property. The legal framework consists therefore primarily of private law. Exclusion orders may not be imposed without reason. Prevention of disorder and harm may be a legitimate reason. The length and range of the ban must relate to the gravity of the disruption. In addition to this, public laws on non-discrimination and privacy are applicable. The civil court is competent to check the exclusion orders in de semi-public domain. The author sees added value in complaints committees, in which both public and private actors partake. Complaint committees can thrive if their assessment frameworks are transparent.

De gevolgen van het arrest ‘Visser Vastgoed’ op de ruimtelijke regulering van kleinhandelsactiviteiten in het Vlaamse Gewest
Auteurs geven aan dat de ruimtelijke regulering van kleinhandelsactiviteiten in het Vlaamse Gewest twee niveaus kent: (1) het vergunningenniveau, hetgeen betekent dat voor het uitvoeren van kleinhandelsactiviteiten, boven bepaalde drempels, een omgevingsvergunning is vereist; (2) het ruimtelijk planniveau, hetgeen betekent dat ruimtelijke ordeningsplannen beperkingen op kleinhandel kunnen bevatten om ruimtelijke redenen of met het oog op de verwezenlijking van de doelstellingen van het integraal handelsvestigingsbeleid. Zij gaan in op het Decreet van 15 juli 2016 betreffende het integraal handelsvestigingsbeleid en op de mogelijke gevolgen van het Hofarrest voor Vlaamse besluitvorming ten aanzien van plannen en vergunningen.

AbstractObjectiveApathy is a common nonmotor symptom in Parkinson's disease (PD) affecting 40% of patients. The aim of the study was to investigate brain changes and correlates of frontal, striatal, and limbic pathways related to subclinical symptoms of apathy in PD patients.MethodsThirty‐two PD patients divided into low‐subclinical symptoms of apathy (LSA) (n = 18) and high‐subclinical symptoms of apathy (HSA) (n = 14) and 25 healthy controls (HC) underwent a T1‐weighted, diffusion‐weighted, and resting‐state functional MRI. Apathy was evaluated with the Lille Apathy Rating Scale. Voxel‐based morphometry, tract‐based spatial statistics, and resting‐state functional connectivity (FC) analyses were performed with a region‐of‐interest approach.ResultsHSA‐PD showed increased white matter axial and mean diffusivity compared with HC and increased white matter axial diffusivity compared with LSA‐PD. HSA‐PD showed decreased fronto‐striatal and fronto‐limbic FC compared with HC and decreased fronto‐striatal FC compared with LSA‐PD. LSA‐PD showed decreased fronto‐limbic but increased fronto‐striatal FC (hyperconnectivity) compared with HC. No significant differences in grey matter were found. Fronto‐striatal FC and white matter axial and mean diffusivity were associated with symptoms of apathy in HSA‐PD. The fronto‐striatal hyperconnectivity was associated with lower symptoms of apathy in LSA‐PD.InterpretationFindings suggest distinct brain alterations in PD groups with subclinical symptoms of apathy. The increased pattern of activation in LSA‐PD, accompanied with lower apathetic symptomatology, might be the initial manifestation of compensatory mechanisms for dysfunctional limbic pathway. The same pattern of hyperconnectivity has been found in other pathologies and the implication of these abnormalities as a cross‐disease model for initial apathy symptomatology is further discussed.

Published: May 2018

ObjectivePatients have a poor understanding of outcomes related to total knee replacement (TKR) surgery, with most patients underestimating the potential benefits and overestimating the risk of complications. In this study, we sought to compare the impacts of descriptive information alone or in combination with an icon array, experience condition (images), or spinner on participants’ preference for TKR.MethodsA total of 648 members of an online arthritis network were randomized to 1 of 4 outcome presentation formats: numeric only, numeric with an icon array, numeric with a set of 50 images, or numeric with a functional spinner. Preferences for TKR were measured before and immediately after viewing the outcome information using an 11‐point numeric rating scale. Knowledge was assessed by asking participants to report the frequency of each outcome.ResultsParticipants randomized to the icon array, images, and spinner had stronger preferences for TKR (after controlling for baseline preferences) compared to those viewing the numeric only format (P < 0.05 for all mean differences). Knowledge scores were highest in participants randomized to the icon array; however, knowledge did not mediate the association between format and change in preference for TKR.ConclusionDecision support at the point‐of‐care is being increasingly recognized as a vital component of care. Our findings suggest that adding graphic information to descriptive statistics strengthens preferences for TKR. Although experience formats using images may be too complex to use in clinical practice, icon arrays and spinners may be a viable and easily adaptable decision aid to support communication of probabilistic information.

AbstractElectronic and photonic fiber devices that can sustain large elastic deformation are becoming key components in a variety of fields ranging from healthcare to robotics and wearable devices. The fabrication of highly elastic and functional fibers remains however challenging, which is limiting their technological developments. Simple and scalable fiber‐processing techniques to continuously codraw different materials within a polymeric structure constitute an ideal platform to realize functional fibers and devices. Despite decades of research however, elastomeric materials with the proper rheological attributes for multimaterial fiber processing cannot be identified. Here, the thermal drawing of hundreds‐of‐meters long multimaterial optical and electronic fibers and devices that can sustain up to 500% elastic deformation is demonstrated. From a rheological and microstructure analysis, thermoplastic elastomers that can be thermally drawn at high viscosities (above 103 Pa s), allowing the encapsulation of a variety of microstructured, soft, and rigid materials are identified. Using this scalable approach, fiber devices combining high performance, extreme elasticity, and unprecedented functionalities, allowing novel applications in smart textiles, robotics, or medical implants, are demonstrated.

Authors: Oami Takehiko , Oshima Taku , Oku Reiko , Nakanishi Kazuya 
Published: May 2018

BackgroundThrombolysis for pulmonary embolism and targeted temperature management for cardiac arrest are controversial treatments in pregnancy.CaseA 37‐year‐old woman at 23 weeks gestation presented with persistent dyspnea. She experienced cardiac arrest soon after arrival at the emergency room. Massive right ventricular dilatation on echocardiography during the transient return of spontaneous circulation suggested pulmonary embolism. We administered recombinant tissue plasminogen activator for suspected pulmonary embolism to successfully resuscitate the patient experiencing refractory cardiac arrest despite heparin infusion. After an additional dose of monteplase for persistent shock with remaining right ventricular dilatation on echocardiography, maternal hemodynamics dramatically improved, but fetal heart rate transiently decreased. Targeted temperature management was initiated for delayed recovery of consciousness. She fully recovered consciousness without neurological deficit. However, the fetus was aborted because of fetal hydrops.ConclusionThrombolysis and targeted temperature management should be considered as treatment options for pulmonary embolism‐induced cardiac arrest during pregnancy.

Published: May 2018

AbstractSilver chalcogenolate cluster assembled materials (SCAMs) are a category of promising light‐emitting materials the luminescence of which can be modulated by variation of their building blocks (cluster nodes and organic linkers). The transformation of a singly emissive [Ag12(SBut)8(CF3COO)4(bpy)4]n (Ag12bpy, bpy=4,4′‐bipyridine) into a dual‐emissive [(Ag12(SBut)6(CF3COO)6(bpy)3)]n (Ag12bpy‐2) via cluster‐node isomerization, the critical importance of which was highlighted in dictating the photoluminescence properties of SCAMs. Moreover, the newly obtained Ag12bpy‐2 served to construct visual thermochromic Ag12bpy‐2/NH2 by a mixed‐linker synthesis, together with dichromatic core–shell Ag12bpy‐2@Ag12bpy‐NH2‐2 via solvent‐assisted linker exchange. This work provides insight into the significance of metal arrangement on physical properties of nanoclusters.
Biomimetic Donor–Acceptor Motifs in Conjugated Polymers for Promoting Exciton Splitting and Charge Separation

Published: May 2018

AbstractNatural photosynthesis serves as a model for energy and chemical conversions, and motivates the search of artificial systems that mimic nature′s energy‐ and electron‐transfer chains. However, bioinspired systems often suffer from the partial or even large loss of the charge separation state, and show moderate activity owing to the fundamentally different features of the multiple compounds. Herein, a selenium and cyanamide‐functionalized heptazine‐based melon (DA‐HM) is designed as a unique bioinspired donor–acceptor (D‐A) light harvester. The combination of the photosystem and electron shuttle in a single species, with both n‐ and p‐type conductivities, and extended spectral absorption, endows DA‐HM with a high efficiency in the transfer and separation of photoexcited charge carriers, resulting in photochemical activity. This work presents a unique conjugated polymeric system that shows great potential for solar‐to‐chemical conversion by artificial photosynthesis.
