Abstract
We present the analysis of the fundamental plane (FP) for a sample of 19 massive red-sequence galaxies (

) in three known overdensities at

from the K-band Multi-object Spectrograph (KMOS) Cluster Survey, a guaranteed-time program with spectroscopy from the KMOS at the VLT and imaging from the Hubble Space Telescope. As expected, we find that the FP zero-point in B band evolves with redshift, from the value 0.443 of Coma to −0.10 ± 0.09, −0.19 ± 0.05, and −0.29 ± 0.12 for our clusters at z = 1.39, z = 1.46, and z = 1.61, respectively. For the most massive galaxies (

) in our sample, we translate the FP zero-point evolution into a mass-to-light-ratio M/L evolution, finding

,

, to

, respectively. We assess the potential contribution of the galaxy structural and stellar velocity dispersion evolution to the evolution of the FP zero-point and find it to be ∼6%–35% of the FP zero-point evolution. The rate of M/L evolution is consistent with galaxies evolving passively. Using single stellar population models, we find an average age of

Gyr for the

galaxies in our massive and virialized cluster at z = 1.39,

Gyr in a massive but not virialized cluster at z = 1.46, and

Gyr in a protocluster at z = 1.61. After accounting for the difference in the age of the universe between redshifts, the ages of the galaxies in the three overdensities are consistent within the errors, with possibly a weak suggestion that galaxies in the most evolved structure are older.
Ejection of Chondrules from Fluffy Matrices
Authors: Arakawa Sota 
Published: September 2017

Abstract
Chondritic meteorites primarily contain millimeter-sized spherical objects, chondrules; however, the co-accretion process of chondrules and matrix grains is not yet understood. In this study, we investigate the ejection process of chondrules via collisions of fluffy aggregates composed of chondrules and matrices. We reveal that fluffy aggregates cannot grow into planetesimals without losing chondrules if we assume that the chondrite parent bodies are formed via direct aggregation of similar-sized aggregates. Therefore, an examination of other growth pathways is necessary to explain the formation of rocky planetesimals in our solar system.

Abstract
We show that the most distant X-ray-detected cluster known to date, Cl J1001 at

, hosts a strong overdensity of radio sources. Six of them are individually detected (within

) in deep

resolution VLA 3 GHz imaging, with

. Of the six, an active galactic nucleus (AGN) likely affects the radio emission in two galaxies, while star formation is the dominant source powering the remaining four. We searched for cluster candidates over the full COSMOS 2 deg2 field using radio-detected 3 GHz sources and looking for peaks in

density maps. Cl J1001 is the strongest overdensity by far with

, with a simple

preselection. A cruder photometric rejection of

radio foregrounds leaves Cl J1001 as the second strongest overdensity, while even using all radio sources Cl J1001 remains among the four strongest projected overdensities. We conclude that there are great prospects for future deep and wide-area radio surveys to discover large samples of the first generation of forming galaxy clusters. In these remarkable structures, widespread star formation and AGN activity of massive galaxy cluster members, residing within the inner cluster core, will ultimately lead to radio continuum as one of the most effective means for their identification, with detection rates expected in the ballpark of 0.1–1 per square degree at

. Samples of hundreds such high-redshift clusters could potentially constrain cosmological parameters and test cluster and galaxy formation models.
A Fast Radio Burst Occurs Every Second throughout the Observable Universe
Authors: Fialkov Anastasia , Loeb Abraham 
Published: September 2017

Abstract
Recent multi-telescope observations of the repeating fast radio burst (FRB) FRB 121102 reveal a Gaussian-like spectral profile and associate the event with a dwarf metal-poor galaxy at a cosmological redshift of 0.19. Assuming that this event represents the entire FRB population, we make predictions for the expected number counts of FRBs observable by future radio telescopes between 50 MHz and 3.5 GHz. We vary our model assumptions to bracket the expected rate of FRBs and find that it exceeds one FRB per second per sky when accounting for faint sources. We show that future low-frequency radio telescopes, such as the Square Kilometre Array, could detect more than one FRB per minute over the entire sky originating from the epoch of reionization.
Le MOOC comme levier d’un processus d’apprentissage organisationnel
Authors: Acquatella François 
Published: September 2017

Considéré comme un des symboles de la révolution numérique, le MOOC est envisagé par Total comme un dispositif susceptible par son utilisation d’enrichir les « capacités » et « capacités dynamiques » des acteurs et de l’organisation, en portant la culture numérique au cœur de l’entreprise. L’objectif de cet article est de déterminer dans quelle mesure le MOOC permet d’intégrer, construire et reconfigurer les compétences au sein de l’organisation. L’analyse à laquelle il a été procédé au travers d’enquêtes (quantitative et qualitative) pour l’élaboration de cet article conduit à définir le MOOC comme levier de création d’une nouvelle compétence organisationnelle. L’usage lié à l’appropriation du dispositif MOOC, pointe une amélioration générale des capacités et compétences favorables au développement de nouvelles routines organisationnelles, représentant également de nouvelles valeurs directrices au sein de l’organisation. Cet article présente une lecture systémique de l’apprentissage organisationnel en lien avec l’approche structurationniste. En ce sens, le MOOC est envisagé comme un dispositif structurant qui dans le même ordre de paradigme, participe d’une vision organisante.
L’impact de la perception des changements organisationnels sur le bien-être des cadres
Authors: Cherkaoui Widad Camille , Jahmane Abderrahman , Montargot Nathalie 
Published: September 2017

Les changements organisationnels sont associés à l’expérience de conditions de travail stressantes, l’incertitude et l’anxiété. Ils peuvent à la fois engendrer du stress et un impact négatif sur le bien-être physique et psychologique des employés. En conséquence, Swanson et Power (2001) suggèrent aux gestionnaires d’accorder une attention toute particulière à la perception des employés durant ces périodes de stress chronique. Cette recherche se focalise sur la manière dont ces changements sont perçus et interprétés, comme un risque ou au contraire un avantage, selon le sens que les individus leur donnent (Mack et al ., 1998 ; Moyle et Parkes, 1999 ; De Zanet et al ., 2004 ; Rafferty et Griffin, 2006). Elle a pour objet d’étudier l’impact de la perception des changements organisationnels sur le bien-être des cadres récemment exposés à des changements organisationnels majeurs. Elle consiste également à proposer des préconisations aux gestionnaires, pour une meilleure réussite de la conduite du changement et aux chercheurs, en termes d’apports et de voies à explorer.
The stability of group formation
Authors: Demange Gabrielle 
Published: September 2017

Dans de nombreuses situations politiques et économiques, deux forces dominent la formation de groupes : d’une part les rendements attendus d’une coordination à l’intérieur d’un groupe croissent avec sa taille, d’autre part la diversité des préférences et des goûts freinent la coordination, défavorisant les groupes larges et hétérogènes. Lorsque ces deux forces, de direction opposée, sont à l’œuvre, on peut s’attendre à la formation de plusieurs groupes disjoints, chacun exploitant les rendements croissants tout en répondant aux préférences de ces membres. Sous quelles conditions peut-on espérer une organisation efficace et stable de la société ? La libre mobilité des individus et la libre formation de coalitions suffisent-elles ? Cet article présente les approches théoriques à ces questions ainsi que quelques études empiriques récentes.
Individual and combined effects of &lt;i&gt;CAPN1&lt;/i&gt;, &lt;i&gt;CAST&lt;/i&gt;, &lt;i&gt;LEP&lt;/i&gt; and &lt;i&gt;GHR&lt;/i&gt; gene polymorphisms on carcass characteristics and meat quality in Holstein bulls

Abstract. The objective of this study was to determine the association of single nucleotide polymorphisms (SNPs) with carcass characteristics and meat quality traits in selected candidate genes in Holstein bulls. Five SNPs in four genes, i.e. calpain 1 (CAPN1), calpastatin (CAST), leptin (LEP) and growth hormone receptor (GHR), were genotyped in 400 purebred bulls using PCR-RFLP. Statistically significant associations were as follows: CAPN1 G316A with live weight, carcass weight, back fat thickness, m. longissimus thoracis et lumborum area and carcass measurements; CAPN1 V530I with pH and L∗; CAST S20T with live weight, inner chest depth and b∗ value; and GHR with ph, a∗ and h∗. In addition, significant genotypic interactions were observed for dressing percentage (LEP A80V  ×  CAST S20T), pH (CAPN1 V530I  ×  GHR S555G and LEP A80V  ×  GHR S555G) and rump width (CAPN1 V530I  ×  CAST S20T). There was no association between the LEP A80V marker and any of the traits evaluated, nor was there any association of the tested SNPs with chest width, C∗ and marbling score. The present results could therefore be indicative for future studies on meat yield and quality.
Decoupling peroxyacetyl nitrate from ozone in Chinese outflows observed at Gosan Climate Observatory

Abstract. We measured peroxyacetyl nitrate (PAN) and other reactive species such as O3, NO2, CO, and SO2 with aerosols including mass, organic carbon (OC), and elemental carbon (EC) in PM2. 5 and K+ in PM1. 0 at Gosan Climate Observatory in Korea (33.17° N, 126.10° E) during 19 October–6 November 2010. PAN was determined through fast gas chromatography with luminol chemiluminescence detection at 425 nm every 2 min. The PAN mixing ratios ranged from 0.1 (detection limit) to 2.4 ppbv with a mean of 0.6 ppbv. For all measurements, PAN was unusually better correlated with PM2. 5 (Pearson correlation coefficient, γ =  0.79) than with O3 (γ =  0.67). In particular, the O3 level was highly elevated with SO2 at midnight, along with a typical midday peak when air was transported rapidly from the Beijing areas. The PAN enhancement was most noticeable during the occurrence of haze under stagnant conditions. In Chinese outflows slowly transported over the Yellow Sea, PAN gradually increased up to 2.4 ppbv at night, in excellent correlation with a concentration increase in PM2. 5 OC and EC, PM2. 5 mass, and PM1. 0 K+. The high K+ concentration and OC ∕ EC ratio indicated that the air mass was impacted by biomass combustion. This study highlights PAN decoupling with O3 in Chinese outflows and suggests PAN as a useful indicator for diagnosing continental outflows and assessing their perturbation of regional air quality in northeast Asia.
Distinct phases of eustatic and tectonic forcing for late Quaternary landscape evolution in southwest Crete, Greece

Published: September 2017

Abstract. The extent to which climate, eustasy and tectonics interact to shape the late Quaternary landscape is poorly known. Alluvial fans often provide useful indexes that allow the decoding of information recorded on complex coastal landscapes, such as those of the eastern Mediterranean. In this paper we analyse and date (using infrared stimulated luminescence (IRSL) dating) a double alluvial fan system on southwest Crete, an island straddling the forearc of the Hellenic subduction margin, in order to constrain the timing and magnitude of its vertical deformation and discuss the factors contributing to its landscape evolution. The studied alluvial system is exceptional because each of its two juxtaposed fans records individual phases of alluvial and marine incision, thus providing unprecedented resolution in the formation and evolution of its landscape. Specifically, our analysis shows that the fan sequence at Domata developed during Marine Isotope Stage (MIS) 3 due to five distinct stages of marine transgressions and regressions and associated river incision, in response to sea-level fluctuations and tectonic uplift at averaged rates of  ∼ 2.2 mm yr−1. Interestingly, comparison of our results with published tectonic uplift rates from western Crete shows that uplift during 20–50 kyr BP was minimal (or even negative). Thus, most of the uplift recorded at Domata must have occurred in the last 20 kyr. This implies that eustasy and tectonism impacted the landscape at Domata over mainly distinct time intervals (e.g. sequentially and not synchronously), with eustasy forming and tectonism preserving the coastal landforms.
Monitoring and modeling infiltration–recharge dynamics of managed aquifer recharge with desalinated seawater

Published: September 2017

Abstract. We study the relation between surface infiltration and groundwater recharge during managed aquifer recharge (MAR) with desalinated seawater in an infiltration pond, at the Menashe site that overlies the northern part of the Israeli Coastal Aquifer. We monitor infiltration dynamics at multiple scales (up to the scale of the entire pond) by measuring the ponding depth, sediment water content and groundwater levels, using pressure sensors, single-ring infiltrometers, soil sensors, and observation wells. During a month (January 2015) of continuous intensive MAR (2.45  ×  106 m3 discharged to a 10.7 ha area), groundwater level has risen by 17 m attaining full connection with the pond, while average infiltration rates declined by almost 2 orders of magnitude (from  ∼  11 to  ∼  0.4 m d−1). This reduction can be explained solely by the lithology of the unsaturated zone that includes relatively low-permeability sediments. Clogging processes at the pond-surface – abundant in many MAR operations – are negated by the high-quality desalinated seawater (turbidity  ∼  0.2 NTU, total dissolved solids  ∼  120 mg L−1) or negligible compared to the low-permeability layers. Recharge during infiltration was estimated reasonably well by simple analytical models, whereas a numerical model was used for estimating groundwater recharge after the end of infiltration. It was found that a calibrated numerical model with a one-dimensional representative sediment profile is able to capture MAR dynamics, including temporal reduction of infiltration rates, drainage and groundwater recharge. Measured infiltration rates of an independent MAR event (January 2016) fitted well to those calculated by the calibrated numerical model, showing the model validity. The successful quantification methodologies of the temporal groundwater recharge are useful for MAR practitioners and can serve as an input for groundwater flow models.
Exceptional retreat of Novaya Zemlya's marine-terminating outlet glaciers between 2000 and 2013
Authors: Carr J. Rachel , Bell Heather , Killick Rebecca , Holt Tom 
Published: September 2017

Abstract. Novaya Zemlya (NVZ) has experienced rapid ice loss and accelerated marine-terminating glacier retreat during the past 2 decades. However, it is unknown whether this retreat is exceptional longer term and/or whether it has persisted since 2010. Investigating this is vital, as dynamic thinning may contribute substantially to ice loss from NVZ, but is not currently included in sea level rise predictions. Here, we use remotely sensed data to assess controls on NVZ glacier retreat between 1973/76 and 2015. Glaciers that terminate into lakes or the ocean receded 3.5 times faster than those that terminate on land. Between 2000 and 2013, retreat rates were significantly higher on marine-terminating outlet glaciers than during the previous 27 years, and we observe widespread slowdown in retreat, and even advance, between 2013 and 2015. There were some common patterns in the timing of glacier retreat, but the magnitude varied between individual glaciers. Rapid retreat between 2000 and 2013 corresponds to a period of significantly warmer air temperatures and reduced sea ice concentrations, and to changes in the North Atlantic Oscillation (NAO) and Atlantic Multidecadal Oscillation (AMO). We need to assess the impact of this accelerated retreat on dynamic ice losses from NVZ to accurately quantify its future sea level rise contribution.
The role of intraoperative optical coherence tomography in pediatric hyphema: a case report
Authors: Coppola Michele , Cicinelli Maria Vittoria , Rabiolo Alessandro , Querques Giuseppe , Bandello Francesco 
Published: September 2017

Purpose: Intraoperative optical coherence tomography (iOCT) is a valuable tool during vitreoretinal surgery, helping the decision-making process. It is particularly useful in pediatric cases to evaluate the macular anatomy intraoperatively, avoiding further potentially dangerous surgery in children. The aim of this report is to describe the role of integrated iOCT in the management of traumatic hyphema in a pediatric patient. Case report: A 5-year-old girl was referred to our department with a history of recent domestic trauma in her right eye. Massive bleeding in the anterior chamber without visualization of the posterior segment was evident. Surgery was planned for the next day under general anesthesia. A 25-G irrigation cannula and 25-G vitrectome were inserted at the limbus into the anterior chamber for removal of the anterior chamber clot. Careful inspection of the posterior pole and retinal periphery to exclude pathologic findings was carried out. A real-time OCT integrated system was used to assess the macular anatomy and the corneal state. The postoperative course was uneventful and full visual recovery was achieved. Conclusions: The objective confirmation of macular integrity by means of iOCT after anterior chamber clearing had great prognostic value, excluding the need for surgical revision with a second general anesthesia in this young patient.

Published: September 2017

Introduction: There have been historical reports on the experiences of patients with total hip arthroplasty (THA) passing through standard metal detectors at airports. The purpose of this study was to analyse those who had recently passed through airport security and the incidence of: (i) triggering of the alarm; (ii) extra security searches; and (iii) perceived inconvenience. Methods: A questionnaire was given to 125 patients with a THA during a follow-up appointment. Those who had passed through airport security after January 2014 met inclusion criteria. A survey was administered that addressed the number of encounters with airport security, frequency of metal detector activation, additional screening procedures utilised, whether security officials required prosthesis documentation, and perceived inconvenience. Results: 51 patients met inclusion criteria. 10 patients (20%) reported triggered security scanners. 4 of the 10 patients stated they had surgical hardware elsewhere in the body. 13 of the 51 patients (25%) believed that having their THA increased the inconvenience of traveling. This is different from the historical cohort with standard metal detectors which patients reported a greater incidence of alarm triggering (n = 120 of 143; p = 0.0001) and perceived inconvenience (n = 99 of 143; p = 0.0001). Discussions: The percentage of patients who have THA triggering security alarms has decreased. Furthermore, the number of patients who feel that their prosthesis caused traveling inconvenience has decreased. We feel that this decrease in alarms triggered and improved perceptions about inconvenience are related to the increased usage of new technology.
The posterior acetabular wall (PAW): an aid to acetabular orientation at primary THA
Authors: Williams Huw L.M. , Bartlett Gavin E. , Norton Mark R. , Middleton Rory G. 
Published: September 2017

Introduction: Incorrect acetabular component positioning during total hip arthroplasty (THA) may lead to dislocation, impingement, wear and revision. Surgeons commonly use the transverse acetabular ligament (TAL) as a landmark for acetabular component orientation. The posterior acetabular wall (PAW) is a structure easily viewed on plain radiography and its position can help guide acetabular component position. In this study, we examine the efficacy of preoperative radiographs in predicting cup position relative to the PAW. Methods: Prospective data was recorded on radiographic findings of the posterior wall (prominent, normal, deficient) on a consecutive series of 200 primary THAs utilising a standardised posterior approach. The final cup position relative to the wall was recorded (prominent, flush, deep). Cup inclination and version were then assessed by postoperative radiography and any instances of dislocation recorded. Results: There were 117 females and 83 males with a mean age of 66.5 years. 154 were recorded as having a normal PAW on radiographs, 152 had the cup positioned in line with the TAL and flush to the PAW. 29 had a deficient PAW and 27 of these had a cup positioned prominently with 17 having a prominent PAW and of these 16 a deep cup position. Postoperative radiographs showed a mean cup version of 20.8° and inclination of 44.7° using this method. There were 21 outliers (10.5%) with no dislocations at a minimum 12-month follow-up. Conclusions: The TAL is a continuation of the posterior labrum. As such, the posterior wall is a useful adjunct to and surrogate landmark for the TAL. It has the added advantage that it is visible on radiographs and so aids surgical planning with respect to cup positioning.

Published: September 2017

Case description We report a reconstructive case in a paraplegic patient, who suffers from a severe proximal femur infection. Aiming at the preservation of the capacity to remain in a seated position to operate a wheelchair, lower leg rotationplasty was considered suitable for reconstruction. Due to severe infection and subclinical femoral artery stenosis, rotationplasty was supercharged by the inferior epigastric artery. Furthermore, extensor tendons of the foot were attached to the acetabulum to facilitate stability of the neo-hip joint. Results Follow-up examination 1 year after surgery revealed no complications and a satisfied patient. Conclusions Especially in paraplegic patients, lower leg rotationplasty is a possible treatment option for severe femoral infection. Supercharging provides well-vascularised tissue to the former infection site and improves wound healing.
