Configuring Spaces : Deploying Organisation.
Despite the wide-spread deployment of Closed Circuit Television (CCTV) throughout most major cities Western Europe, and the importance of surveillance to contemporary debates within the social sciences, there remains relatively little detailed research concerned with the ways in which these technologies are used to oversee and manage complex spatial environments. In this paper, we examine how personnel in the operation centres of an unban transport system, or metro, use a range of tools and technologies to identify problems and events and implement a coordinated response. We consider how personnel configure views of the space to make sense of and interpret the conduct of the travelling public in organisationally relevant ways. We examine how they shape the ways in which both passengers and staff see and respond to each others' actions and the spatial environment. In addressing how personnel constitute the sense and significance of the scenes, we reflect on the development of information systems that are designed to scrutinise video images and automatically detect problems and events.

Quantification Abilities during Childhood : Should we Scrap the Geneva Perspective ?
Nowadays Geneva perspective is hardly ever considered by psychologists in order to explain the emergence of quantification abilities during childhood. The goal of this paper is to summarize this constructivist perspective and to evaluate its relevancy with post-piagetian empirical data. Up to date the available results do not allow a systematic rejection of the Swiss researchers’ point of view.
Remarques d’inspiration phénoménologique sur la phénoménalité du virtuel
Authors: Sebbah François-David 
Published: November 2018

Some phenomenologically inspired remarks on the phenomenal aspect of the virtual.
This article attempts to give a phenomenologically-inspired description of the specific sort of phenomenality that is produced by Virtual Reality (VR), and in particular to distinguish it from so-called “ natural” perception and from imagination. This raises a number of fundamental philosophical issues, such as the opposition between reality and illusion ; the phenomenological approach adopted here seeks to find in the “ thing itself” which is described the means to overcome this sort of opposition. In the course of this description, we are led : 1) to insist on the fact that VR does seem to require abandoning the representational paradigm ; 2) to specify the status of the lived body and lived experience in virtual environments, 3) to emphasize that reality is “ that which resists”, and that the genericity of virtual entities is decisive as a criterion for distinguishing between VR and the phenomenality of natural perception.
Semiotic Evolution of Toolmaking: the Role of Symbols for Work towards Delayed Reward

L'évolution sémiotique de la fabrication d'outils : le rôle des symboles pour un travail avec récompense différée.
Les outils dépendent des modèles mentaux qui servent de médiateurs dans leur production par le biais d’actes moteurs. Étant donné que les outils sont une des expressions du comportement sémiotique général, la caractérisation sémiotique de la manufacture des armes au Néolithique peut permettre d’élucider les divers processus cognitifs sous-jacents aux origines de la production d’outils. La corrélation spatio-temporelle est la propriété définissant les indices, alors que les symboles se caractérisent par le fait d’être régis par des lois. Des pierres prises et jetées sur une proie ou sur un prédateur peuvent instantanément être des indices de lutte et de classification sociale, mais des armes en pierre soigneusement manufacturées, qui demandent un long travail élaboré et fatiguant, demandent nécessairement la présence d’une association symbolique entre des habitudes motrices complexes et des images anticipant l’usage fructueux de ces mêmes outils, c’est-à-dire des classes spécifiques d’effets possibles, comme pourraient l’être la capture, la mise à mort, le transport, la préparation, le partage ou la consommation des proies. La symbolisation des outils lors de la manufacture permettrait de relier les traces mnémoniques actives au niveau du cortex cérébral et de l’hippocampe aux circuits limbiques liés aux émotions et au système de récompenses. Ceci fournirait la motivation nécessaire pour accomplir un travail orienté vers un but lointain, par l’activation prolongée et répétitive du cortex moteur et du strié. La progressive symbolisation des gestes, des postures, des vocalisations, des dessins sur le sable ainsi que la peinture murale constituèrent probablement, avec les rêves représentant la chasse et l’ensemble des symboles précédemment mentionnés, la motivation première de la production des armes au Néolithique. Notre hypothèse est que, sans ce travail de symbolisation, toute production d’outils au Néolithique aurait été impossible.
Observations morphologiques sur le géosystème karstique du Rupt du Puits (Meuse, France)

Morphological observations on the karst system of Rupt-du-Puits (Lorraine, France)
The karst system of Rupt-du-Puits is situated east of the Paris basin (Barrois and Perthois), in the Portlandian limestones covered by sands and clays of Lower Cretaceous. It presents 21 km of surveyed passages in several networks (catchment = 13 km²). In this typical covered karst (cryptokarst), we observe two kinds of alimentation : rapid (swallow holes) and slow (wet soils). On the exokarst, the valleys move by retreat of swallow holes and karst stepping. In the endokarst, the variations of the base level determine several stages of stream piracy (elbows of capture). The karst morphology depends on climatic changes and the evolution of the drainage pattern during the Upper Pleistocene.

Recordings of the slope movements by speleothems (Le Tignet,
Alpes-Maritimes, France).
The study of speleothems in a sub-cutaneous cave developed between a scree and its bedrock, shows the slope movements. All the speleothem couples (stalactite facing a stalagmite) are displaced. Among the speleothems, a 50 cm long thin stalactite (soda-straw type) has recorded the movements that have affected the slope. Every slope movement is shown in a speleothem axis variation. Radiocarbon datings help define growth speed and make clear the movement history over a 30,000 year period. This analysis confirms the possibility of using speleothem as verticality gauges to define an area stability.

Abstract
The phase function of the dust coma of comet 67P has been determined from Rosetta/OSIRIS images. This function shows a deep minimum at phase angles near 100°, and a strong backscattering enhancement. These two properties cannot be reproduced by regular models of cometary dust, most of them based on wavelength-sized and randomly oriented aggregate particles. We show, however, that an ensemble of oriented elongated particles of a wide variety of aspect ratios, with radii r ≳ 10 μm, and whose long axes are perpendicular to the direction of the solar radiation, are capable of reproducing the observed phase function. These particles must be absorbing, with an imaginary part of the refractive index of about 0.1 to match the expected geometric albedo, and with porosity in the 60%–70% range.

Abstract
We report the discovery of a giant planet in the KMT-2016-BLG-1397 microlensing event, which was found by The Korea Microlensing Telescope Network alone. The timescale of this event is t
E = 40.0 ± 0.5 days, and the mass ratio between the lens star and its companion is q = 0.016 ± 0.002. The planetary perturbation in the light curve is a smooth bump, resulting in the classical binary-lens/binary-source (2L1S/1L2S) degeneracy. We measure the V − I color of the (putative) two sources in the 1L2S model, and then effectively rule out the binary-source solution. The finite-source effect is marginally detected. Combined with the limits on the blend flux and the probability distribution of the source size normalized by the Einstein radius ρ, a Bayesian analysis yields the lens mass

kpc. Thus, the companion is a super-Jupiter of a mass

, at a projected separation

au, indicating that the planet is well beyond the snow line of the host star.
Magnetohydrodynamic Modeling of a Solar Eruption Associated with an X9.3 Flare Observed in the Active Region 12673
Authors: Inoue Satoshi , Shiota Daikou , Bamba Yumi , Park Sung-Hong 
Published: November 2018

Abstract
On 2017 September 6, the solar active region 12673 produced an X9.3 flare, regarded to be the largest to have occurred in solar cycle 24. In this work we have performed a magnetohydrodynamic (MHD) simulation in order to reveal the three-dimensional (3D) dynamics of the magnetic fields associated with the X9.3 solar flare. We first performed an extrapolation of the 3D magnetic field based on the observed photospheric magnetic field prior to the flare and then used this as the initial condition for the MHD simulation, which revealed a dramatic eruption. In particular, we found that a large coherent flux rope composed of highly twisted magnetic field lines formed during the eruption. A series of small flux ropes were found to lie along a magnetic polarity inversion line prior to the flare. Reconnection occurring between each flux rope during the early stages of the eruption formed the large, highly twisted flux rope. Furthermore, we observed a writhing motion of the erupting flux rope. Understanding these dynamics is important in the drive to increase the accuracy of space weather forecasting. We report on the detailed dynamics of the 3D eruptive flux rope and discuss the possible mechanisms of the writhing motion.
Coronal Hard X-Ray Sources Revisited

Published: November 2018

Abstract
This paper reports on the re-analysis of solar flares in which the hard X-rays (HXRs) come predominantly from the corona rather than from the more usual chromospheric footpoints. All of the 26 previously analyzed event time intervals, over 13 flares, are re-examined for consistency with a flare model in which electrons are accelerated near the top of a magnetic loop which has a sufficiently high density to stop most of the electrons by Coulomb collisions before they can reach the footpoints. Of particular importance in the previous analysis was the finding that the length of the coronal HXR source increased with energy in the 20–30 keV range. However, after allowing for the possibility that footpoint emission at the higher energies affects the inferred length of the coronal HXR source, and using analysis techniques that suppress the possible influence of such footpoint emission, we conclude that there is no longer evidence that the length of the HXR coronal sources increase with increasing energy. In fact, for the six flares and 12 time intervals that satisfied our selection criteria, the loop lengths decreased on average by 1.0 ± 0.2 arcsec between 20 and 30 keV, with a standard deviation of 3.5 arcsec. We find strong evidence that the peak of the coronal HXR source increases in altitude with increasing energy. For the thermal component of the emission, this is consistent with the standard CHSKP flare model in which magnetic reconnection in a coronal current sheet results in new hot loops being formed at progressively higher altitudes. The explanation for the nonthermal emission is not so clear.
The Coronal Volume of Energetic Particles in Solar Flares as Revealed by Microwave Imaging

Abstract
The spectrum of gyrosynchrotron emission from solar flares generally peaks in the microwave range. Its optically thin, high-frequency component, above the spectral peak, is often used for diagnostics of the nonthermal electrons and the magnetic field in the radio source. Under favorable conditions, its low-frequency counterpart brings additional, complementary information about these parameters as well as thermal plasma diagnostics, either through gyrosynchrotron self-absorption, free–free absorption by the thermal plasma, or the suppression of emission through the so-called Razin effect. However, their effect on the low-frequency spectrum is often masked by spatial nonuniformity. To disentangle the various contributions to low-frequency gyrosynchrotron emission, a combination of spectral and imaging data is needed. To this end, we have investigated Owens Valley Solar Array (OVSA) multi-frequency images for 26 solar bursts observed jointly with RHESSI during the first half of 2002. For each, we examined dynamic spectra, time- and frequency-synthesis maps, RHESSI images with overlaid OVSA contours, and a few representative single-frequency snapshot OVSA images. We focus on the frequency dependence of microwave source sizes derived from the OVSA images and their effect on the low-frequency microwave spectral slope. We succeed in categorizing 18 analyzed events into several groups. Four events demonstrate clear evidence of being dominated by gyrosynchrotron self-absorption, with an inferred brightness temperature of ≥108 K. The low-frequency spectra in the remaining events are affected to varying degrees by Razin suppression. We find that many radio sources are rather large at low frequencies, which can have important implications for solar energetic particle production and escape.
A Global ILC Approach in Pixel Space over Large Angular Scales of the Sky Using CMB Covariance Matrix
Authors: Sudevan Vipin , Saha Rajib 
Published: November 2018

Abstract
We propose a new internal linear combination (ILC) method in the pixel space, applicable on large angular scales of the sky, to estimate a foreground-minimized cosmic microwave background (CMB) temperature anisotropy map by incorporating prior knowledge about the theoretical CMB covariance matrix. The usual ILC method in pixel space, on the contrary, does not use any information about the underlying CMB covariance matrix. The new approach complements the usual pixel space ILC technique specifically at low-multipole regions, using global information available from the theoretical CMB covariance matrix and from the data. Since we apply our method over the large scale on the sky containing low multipoles, we perform foreground minimization globally. We apply our methods on low-resolution Planck and WMAP foreground-contaminated CMB maps and validate the methodology by performing detailed Monte Carlo simulations. Our cleaned CMB map and its power spectrum have significantly less error than those obtained following the usual ILC technique at low resolution that does not use CMB covariance information. Another very important advantage of our method is that the cleaned power spectrum does not have any negative bias at the low multipoles because of effective suppression of CMB–foreground chance correlations on large angular scales of the sky. Our cleaned CMB map and its power spectrum match well with those estimated by other research groups.
Le vote à l’épreuve du couple

L’analyse des processus de socialisation se concentre généralement sur les relations entre parents et enfants ou au sein de groupes de pairs. Dans cet article, nous étudions ces processus au sein du couple en décryptant ce que le couple fait au vote et inversement. L’étude s’appuie sur des matériaux quantitatifs, tirés d’un questionnaire administré à la sortie des urnes lors de l’élection présidentielle de 2017 et sur des entretiens réalisés lors de quatre vagues auprès d’individus en couple hétérosexuel. L’influence du couple dans la formation des opinions politiques doit être pensée en relation avec d’autres variables (en particulier, la classe, l’âge et l’héritage politique) et étudiée dans son environnement en prenant en compte les réseaux de chaque conjoint dans une perspective dynamique en termes de « carrières ».
Optical Factors in Increased Best Spectacle-corrected Visual Acuity After LASIK
Authors: Erdem Uzeyir , Muftuoglu Orkun 
Published: November 2018

ABSTRACT
PURPOSE: To study the factors that correlate with improved best spectacle-corrected visual acuity (BSCVA) after LASIK.
METHODS: This was a nonrandomized, prospective clinical trial of 850 eyes from 480 patients undergoing LASIK for myopia, hyperopia, and mixed astigmatism. The mean preoperative spherical equivalent refraction was -3.75±4.82 diopters (D) (range: -13.88 to 6.00 D). From this population, 72 eyes (including 22 amblyopic eyes) from 43 patients were found to have improved BSCVA 6 months after LASIK. All patients underwent LASIK with the NAVEX platform. These eyes were analyzed to evaluate factors that correlated with improved BSCVA. Pre- and postoperative BSCVA, refraction, pupil diameter, corneal topography, asphericity (Q value), total aberrations, and higher order wavefront aberrations were analyzed. All wavefront aberrations were measured using the NIDEK Optical Path Difference Scan aberrometer (OPD-Scan) preoperatively and at 6 months postoperatively.
RESULTS: Postoperatively, the mean sphere was -0.44±1.30 D (range: -4.50 to +2.50 D). The mean increase in BSCVA was 0.15±0.09 logMAR. A statistically significant negative correlation was observed between the increase in BSCVA and the preoperative BSCVA (P<.01). Mixed astigmatic and highly myopic eyes are more likely to gain BSCVA after LASIK than moderately myopic (P<.05) and hyperopic eyes (P<.001). In patients with myopia, the amount of BSCVA improvement correlated with the magnitude of the correction (P<.05). The induction of spherical aberration negatively correlated with the increase in BSCVA (P<.05). There were no significant differences between normal eyes and amblyopic eyes with respect to postoperative improvement in BSCVA (P>.05).
CONCLUSIONS: Decreased preoperative BSCVA, lower total spherical aberration induction, and preoperative mixed astigmatism and high myopia correlate with an increase in BSCVA after LASIK. [J Refract Surg. 2006;22: S1056-S1068.]

Authors: Meshi Amit , Camacho Natalia , Lin Tiezhu , Muftuoglu Ilkay K. , Arcinue Cheryl A. , Gaber Raouf , You Qi Sheng , Freeman William R. 
Published: November 2018

BACKGROUND AND OBJECTIVE:
To compare subfoveal disciform scars with good and poor vision in patients with neovascular age-related macular degeneration (nAMD).

PATIENTS AND METHODS:
A retrospective case-control study. Twenty-two eyes of 21 consecutively treated patients with nAMD with subfoveal disciform scar and best-corrected visual acuity (BCVA) of 20/63 or better at the final visit were included. Twenty-one eyes of 21 matched patients with disciform scar and final BCVA less than 20/63 served as controls.

RESULTS:

Subretinal pigment epithelium scar location was more common in the good vision group than in the poor vision group (
P
< .001). The mean percent disruption of the ellipsoid and the external limiting membrane layers was significantly greater in poor vision eyes than in good vision eyes from scar formation and throughout follow-up (all
P
< .01).

CONCLUSION:
Preserved photoreceptor layer correlated with good vision in patients with nAMD and subfoveal disciform scar.

Morphological Difference of Choroidal Vasculature Between Polypoidal Choroidal Vasculopathy and Neovascular AMD on OCT: From the Perspective of Pachychoroid
Authors: Lai Kunbei , Zhou Lijun , Zhong Xiaojin , Huang Chuangxin , Gong Yajun , Xu Fabao , Ma Li , Chen Guandi , Cheng Lin , Lu Lin , Jin Chenjin 
Published: November 2018

BACKGROUND AND OBJECTIVE:
To investigate the morphological difference of choroidal vasculature between polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (nAMD) on optical coherence tomography (OCT).

PATIENTS AND METHODS:
One hundred eighty-nine patients with macula-involved PCV (n = 107) or nAMD (n = 82) were retrospectively reviewed. The subfoveal choroidal thickness (SFCT) and thickness of the Haller's layer were determined on enhanced depth imaging optical coherence tomography (EDI-OCT). The mean diameters of subfoveal large choroidal vessels were also calculated.

RESULTS:

Both the SFCT (257.31 μm ± 100.50 μm vs. 209.95 μm ± 97.51 μm) (
P
< .01) and the thickness of the Haller's layer (213.68 μm ± 82.65 μm vs. 159.67 μm ± 79.86 μm) (
P
< .01) were greater in PCV patients than nAMD patients. The ratio of thickness of the Haller's layer to the SFCT was higher in the PCV group (0.83 ± 0.07) than the nAMD group (0.7 5± 0.11) (
P
< .01). The mean diameter of subfoveal large choroidal vessels was greater in PCV patients (163.55 μm ± 62.23 μm vs. 112.81 ± 58.87 μm) (
P
< .01).

CONCLUSION:
Choroidal thickening and dilation of large choroidal vessels were commonly seen in PCV patients, supporting that PCV belongs to the pachychoroid spectrum disorders and might be a different entity from nAMD.
