Abstract
Background
We implemented a high-protein diet (2 g·kg−1·d−1) throughout 12 weeks of concurrent exercise training to determine whether interferences to adaptation in muscle hypertrophy, strength and power could be attenuated compared to resistance training alone.

Methods
Thirty-two recreationally active males (age: 25 ± 5 years, body mass index: 24 ± 3 kg·m−2; mean ± SD) performed 12 weeks of either isolated resistance (RES; n = 10) or endurance (END; n = 10) training (three sessions·w−1), or concurrent resistance and endurance (CET; n = 12) training (six sessions·w−1). Maximal strength (1RM), body composition and power were assessed pre- and post-intervention.

Results
Leg press 1RM increased ~ 24 ± 13% and ~ 33 ± 16% in CET and RES from PRE-to-POST (P < 0.001), with no difference between groups. Total lean mass increased ~ 4% in both CET and RES from PRE-to-POST (P < 0.001). Ultrasound estimated vastus lateralis volume increased ~ 15% in CET and ~ 11% in RES from PRE-to-POST (P < 0.001), with no difference between groups. Wingate peak power relative to body mass displayed a trend (P = 0.053) to be greater in RES (12.5 ± 1.6 W·kg BM−1) than both CET (10.8 ± 1.7 W·kg BM−1) and END (10.9 ± 1.8 W·kg BM−1) at POST. Absolute VO2peak increased 6.9% in CET and 12% in END from PRE-to-POST (P < 0.05), with no difference between groups.

Conclusion
Despite high protein availability, select measures of anaerobic power-based adaptations, but not muscle strength or hypertrophy, appear susceptible to ‘interference effects’ with CET and should be closely monitored throughout training macro-cycles.

On the impulse response and global instability development of the infinite rotating-disc boundary layer
Authors: Thomas Christian , Davies Christopher 
Published: October 2018

Linear disturbance development in the von Kármán boundary layer on an infinite rotating-disc is investigated for an extensive range of azimuthal mode numbers$n$. The study expands upon earlier investigations that were limited to those values of$n$located near the onset of absolute instability (Lingwood,J. Fluid Mech., vol. 299, 1995, pp. 17–33), where disturbances to the genuine inhomogeneous flow were shown to be globally stable (Davies &amp; Carpenter,J. Fluid Mech., vol. 486, 2003, pp. 287–329). Numerical simulations corresponding to azimuthal mode numbers greater than the conditions for critical absolute instability display a form of global linear instability that is characterised by a faster than exponential temporal growth, similar in appearance to that found on the rotating-disc with mass suction (Thomas &amp; Davies,J. Fluid Mech., vol. 724, 2010, pp. 510–526) and other globally unstable flows (Huerre &amp; Monkewitz,Annu. Rev. Fluid Mech., vol. 22, 1990, pp. 473–537). Solutions indicate that a change in the global behaviour arises for $n\in [80:100]$that is marginally greater than those disturbances studied previously. Furthermore, the Reynolds number associated with the larger azimuthal mode numbers coincides with the upper bound of experimental predictions for transition. Thus, the local–global linear stability of the infinite rotating-disc is similar to the scenario outlined by Huerre &amp; Monkewitz (1990) that states a region of local absolute instability is necessary but not sufficient for global instability to ensue. Conditions are derived to predict the azimuthal mode number needed to bring about a change in global behaviour, based on solutions of the linearised complex Ginzburg–Landau equation coupled with numerical simulations of disturbances to the radially homogeneous flow. The long term response is governed by a detuning effect, based on radial variations of the temporal frequency and matching shifts in temporal growth that increases for larger$n$, eventually attaining values sufficient to engineer global linear instability. The analysis is extended to include mass transfer through the disc surface, with similar conclusions drawn for disturbances to large enough azimuthal mode numbers. Finally, we conclude that the high$n$modes are unlikely to have a strong influence on disturbance development and transition in the von Kármán flow, as they will be unable to establish themselves across an extended radial range before nonlinear effects are triggered by the huge growth associated with the wavepacket maxima of the lower$n$-valued convective instabilities.
Is It Who You Know or What You Know? Evidence from IPO Allocations and Mutual Fund Performance
Authors: Hwang Chuan-Yang , Titman Sheridan , Wang Yuxi 
Published: October 2018

Mutual fund managers with degrees from elite universities tend to outperform their counterparts from less elite universities. We show that the better performance of elite graduates is generated from their better connections with underwriters that facilitate allocations to underpriced initial public offerings (IPOs). Indeed, we find that the funds outperformonlyin months when they are connected to underwriters issuing IPOs. A strategy of buying mutual funds in months when they are connected to underwriters scheduled to issue IPOs generates significant abnormal returns, as high as 4.08% per annum in hot markets.
The Term Structure of Expected Recovery Rates
Authors: Doshi Hitesh , Elkamhi Redouane , Ornthanalai Chayawat 
Published: October 2018

There is widespread agreement that corporate debts’ recovery rates are time varying, but empirical work in this area is limited. We show that the joint information from the term structure of senior and subordinate credit default swaps can identify the level and the dynamics of recovery rates. We estimate a reduced-form no-arbitrage model on 46 firms across different industries. We find that the term structure of expected recovery rates is, on average, downward sloping. However, an inversion occurs during the 2008 crisis, suggesting the market expects higher recoveries conditional on short-term survival. The inversion is more pronounced for firms in distressed industries.
Le salut en perspective: Un essai d'interprétation de la Flagellation du Christ de Piero della Francesca
Authors: Mercier Franck 
Published: October 2018

RésuméChef-d’œuvre absolu de la perspective linéaire, véritable icône de la Renaissance, la Flagellation du Christ de Piero della Francesca (conservé à la Galleria Nazionale delle Marche, à Urbino) constitue l'une des grandes énigmes picturales du Quattrocento italien. L'incertitude ne porte pas seulement sur la datation ou sur la destination primitive du tableau, mais encore et surtout sur le sujet représenté. En dépit de longues discussions sur la signification globale de l'image, en particulier à propos de l'identification des trois figures situées à l'avant-plan, la Flagellation reste un profond mystère. Dans le prolongement d'une riche et abondante tradition herméneutique, cet article propose une nouvelle interprétation de cette célèbre peinture qui s’écarte d'une lecture politique (fondée sur ses liens supposés avec l'Empire byzantin) ainsi que de la vision traditionnelle affirmant la banalité de son iconographie. L'analyse de la géométrie de l'espace pictural et de sa signification théologique potentielle conduit à reconsidérer le tableau comme une méditation visuelle sur la temporalité inspirée par saint Augustin, en même temps qu'un exercice spirituel singulier.
Un atelier italien à la cour d'Avignon: Matteo Giovannetti, peintre du pape Clément VI (1342-1352)
Authors: Anheim Étienne 
Published: October 2018

RésuméLe peintre Matteo Giovannetti, originaire de Viterbe, s'installe à la cour des papes d'Avignon au début des années 1340. Durant le règne du pape Clément VI (1342-1352), il parvient à organiser autour de lui un atelier curial d'une dimension inédite, dont les archives administratives pontificales ont conservé de nombreuses traces. Cette documentation exceptionnelle permet de reconstituer les phases de développement administratif, financier, matériel et technique de cet atelier, qui correspondent à l'affirmation progressive de la position artistique de Matteo. Ce dernier s'appuie non seulement sur la maîtrise de la nouvelle culture visuelle italienne, mais aussi sur des innovations techniques dans la production de la fresque et des pratiques d'organisation du chantier et d’écriture comptable. L’étude de l'atelier de Matteo éclaire ainsi la figure de l'artiste à la fois artisan, courtisan et entrepreneur, mais aussi la dimension collective et matérielle du travail créateur dans l'Europe du xive siècle.
La musique en prison: La campagne pour la libération de Miguel Angel Estrella, 1977-1980
Authors: Buch Esteban , Fléchet Anaïs 
Published: October 2018

RésuméEn décembre 1977, le pianiste argentin Miguel Angel Estrella est arrêté à Montevideo dans le cadre de l'opération Cóndor. Accusé d'appartenir à la guérilla péroniste Montoneros, il est torturé et maintenu au secret avant d’être transféré dans la prison de Libertad où sont rassemblés tous les prisonniers politiques de l'Uruguay. Au terme d'une intense campagne de solidarité internationale – lancée par ses amis parisiens et menée par des personnalités du monde de la musique, des diplomates et des militants des droits de l'homme, mais aussi par de nombreux mélomanes anonymes –, il est libéré et expulsé vers la France en février 1980. Fondé sur les archives du comité de soutien d'Estrella, des sources diplomatiques et une série d'entretiens, ainsi que sur les fonds récemment déclassifiés de la justice militaire uruguayenne, cet article décrit les ressorts d'une cause exceptionnelle, éclairant d'un jour nouveau les liens entre musique et diplomatie au temps de la guerre froide. Il interroge aussi l'expérience vécue par le musicien en prison, où la pénible reproduction d’œuvres de Beethoven sur un piano muet fait écho à l'assimilation, dans les médias, de sa figure à un héros beethovénien, sorte de Florestan moderne. Ainsi, l'article se penche sur les liens entre éthique et esthétique, et analyse la façon dont l’émotion s'articule au politique dans les mobilisations internationales.
Le silencement du monde: Paysages sonores au haut Moyen Âge et nouvelle culture aurale
Authors: Pancer Nira 
Published: October 2018

RésuméAlors que les textes antiques abondent en informations sur le paysage sonore, les textes altimédiévaux restent très silencieux. Que s'est-il produit lors du passage de l'Antiquité au haut Moyen Âge pour que le répertoire des manifestations acoustiques s'amenuise de manière aussi sensible ? Ce « silencement du monde » est-il l'indice d'une mutation du paysage sonore « objectif » que l'on pourrait attribuer à des changements dans les conditions matérielles et/ou celui d'une profonde mutation de la culture aurale ? S'il est raisonnable de supposer que la transformation des infrastructures explique en partie le recul du bruit, elle ne permet pas pour autant d’élucider l’énigme de la raréfaction des indications sonores dont témoignent les textes. Pour comprendre les enjeux qui se cachent derrière ce phénomène, il faut prendre en compte la dimension didactique de la littérature hagiographique et les motivations théologiques des auteurs dont le but est de sensibiliser les fidèles à une « sonographie sacrée ».
Comparative Analysis of the Japanese Version of the Revised Impact of Event Scale: A Study of Firefighters
Authors: Mitani Satoko 
Published: October 2018

AbstractIntroduction:The Impact of Event Scale Revised (IES-R) has been used in various epidemiological studies to assess the prevalence of post-traumatic stress disorder (PTSD). Previous studies using the IES-R Japanese version to assess the mental health of firefighters were based on the premise that firefighters had experienced a traumatic event(s) as a matter of course. However, use of the IES-R-J does not indicate whether or not a traumatic event was experienced. The purpose of this study is to clarify the differences between: (1) IES-R-J high and low score groups; and (2) those who report symptoms similar to those of PTSD with and without having been being exposed to a traumatic event.Methods:Questionnaire packets distributed to all 157 workers in a Japanese fire station included the IES-R, the Japan Brief Job Stress Questionnaire, a questionnaire regarding traumatic event experiences, and demographic questions. Participants who scored ≥25 points on the IES-R-J scale were defined as the PTSD high risk (HR) group; those with scores <25 points as the PTSD low risk (LR) group.Results:One hundred thirty-one of the 157 subjects (83.4%) responded to the questionnaire; three were excluded from the analysis because of missing data. The mean total IES-R-J score was 14.9 ±15.2. Twenty-eight subjects scored in the PTSD HR group (≥25); 100 scored in the LR group (<25). A total of 54 (42.2%) participants had experienced a traumatic event; 57.8% had not. In the HR group, 14 subjects had experienced a traumatic event and 14 had not. Participants who had experienced a traumatic event reported a higher incidence of intrusion/re-experience symptoms than did those who had not experienced a traumatic event. The level of social support significantly affected the risk for PTSD.Firefighters who scored ≥25 on the IES-R-J and, thus, considered to be at high risk for the development of PTSD, were less confident about their health, experienced more job stressors and had less social support than did those whose IES-R-J scores were <25. Having experienced a traumatic event was reported by only 42% of all the participants and by only 50% of those in the high risk PTSD group.Conclusions:Although the IES-R is an easily-administered tool useful in epidemiological studies evaluating psychological stress, it is recommended that the questionnaire be amended to include a question regarding the existence of a threatened experience or event and to analyze the data using positive and negative predictive value methodology.
Factors that Influence Medical Reserve Corps Recruitment

Published: October 2018

AbstractThe Medical Reserve Corps (MRC) is a key strategy used in the United States to assure an adequate surge capacity healthcare workforce for response to disasters. A survey of Hawaiian healthcare providers (n = 1,057) was conducted to identify factors that influence interest, ability, and willingness to join the MRC; 468 (44.3%) healthcare providers responded. Overall, females were more likely to demonstrate an interest in joining the MRC, while physicians and dentists reported lower levels of ability and willingness, in addition to a lower level of interest in joining the MRC than the other professional groups. The most important motivating factor in joining the MRC was altruism and the ability to help one's own community. Respondents reported a number of factors that would influence their decision to join or remain a MRC member. These included: (1) time commitment required; (2) MRC organization and management; (3) provision of MRC-sponsored training or education sessions and continuing education credits; (4) concerns regarding the safety of family members during a disaster; (5) professional liability protection for work performed during MRC operations; and (6) competing personal obligations. Strategies targeting these factors probably will be most effective in recruitment and retention of MRC volunteers as well as members of other public health surge capacity volunteer groups.

AbstractHot Flow Anomalies (HFAs) are transients observed at planetary bow shocks, formed by the shock interaction with a convected interplanetary current sheet. The primary interpretation relies on reflected ions channeled upstream along the current sheet. The short duration of HFAs has made direct observations of this process difficult. We employ high resolution measurements by NASA's Magnetospheric Multiscale Mission to probe the ion microphysics within a HFA. Magnetospheric Multiscale Mission data reveal a smoothly varying internal density and pressure, which increase toward the trailing edge of the HFA, sweeping up particles trapped within the current sheet. We find remnants of reflected or other backstreaming ions traveling along the current sheet, but most of these are not fast enough to out‐run the incident current sheet convection. Despite the high level of internal turbulence, incident and backstreaming ions appear to couple gyro‐kinetically in a coherent manner.
Evolution of Submesoscale Ageostrophic Motions Through the Life Cycle of Oceanic Mesoscale Eddies
Authors: Zhang Zhengguang , Qiu Bo 
Published: October 2018

AbstractThe global ocean circulation is forced by large‐scale fluxes at the surface and dissipated at small scales by diffusion. To achieve a long‐term equilibrium requires a dynamical route that transfers energy from large to dissipative scales. The submesoscale ageostrophic motions (1–50 km) have been hypothesized recently to play a critical role in this route by extracting energy from mesoscale eddies (50–500 km) that contain the majority of oceanic kinetic energy. By combining global surface velocity measurements by drifters and satellite altimeter‐tracked eddy data set, we show that the submesoscale ageostrophic kinetic energy exhibits unexpected global mean features through the life cycle of mesoscale eddies. The ageostrophic energy is relatively small in eddy's mature phase but is large both in formation/decaying phases. Furthermore, the energy level of ageostrophic motions depends positively on the local geostrophic strain rate, suggesting that the geostrophic deformation field may dictate the energy transfer from mesoscale eddies to submesoscale motions.
Insights Into the Kinematic Rupture of the 2015 Mw 8.3 Illapel, Chile, Earthquake From Joint Analysis of Geodetic, Seismological, Tsunami, and Superconductive Gravimeter Observations

AbstractWe investigated the spatiotemporal slip distribution of the 2015 Illapel earthquake (Mw = 8.3) by joint analyses of geodetic, seismological, tsunami, and superconductive gravimeter observations. The coseismic rupture directly overlaps the interseismic coupling zone determined by onshore geodetic measurements. The main slip asperity is located north of the hypocenter with a peak slip of ~9.2 m, and the rupture spans ~200 km along strike and ~150 km along dip with an average rupture speed of ~2.0 km/s. Most aftershocks reveal a clear complementary distribution with the coseismic rupture; that is, aftershock clusters are located at the border of unbroken barriers and regions of sudden transition from high to low rupture area. The calculated Coulomb failure stress changes indicate that 80% of the aftershocks were triggered by the main event. The low‐frequency radiation corresponds to the large coseismic rupture at the shallow portion of the megathrust, while the high‐frequency radiation is associated with the edge of large slip asperity or an isolated patch at a deeper position. The large coseismic slip region correlates well with the high Vp/Vs ratio of the subduction interface, which implies that the Illapel earthquake might nucleate at a relatively weak patch within a strong coupled zone. Furthermore, we argue that the coseismic slip did reach to the trench from tsunami simulations, and historical earthquakes analyses indicate a complex strain accumulation and release in central Chile.

AbstractThermokarst lakes are prevalent in Arctic coastal lowland regions and sublake permafrost degradation and talik development contributes to greenhouse gas emissions by tapping the large permafrost carbon pool. Whereas lateral thermokarst lake expansion is readily apparent through remote sensing and shoreline measurements, sublake thawed sediment conditions and talik growth are difficult to measure. Here we combine transient electromagnetic surveys with thermal modeling, backed up by measured permafrost properties and radiocarbon ages, to reveal closed‐talik geometry associated with a thermokarst lake in continuous permafrost. To improve access to talik geometry data, we conducted surveys along three transient electromagnetic transects perpendicular to lakeshores with different decadal‐scale expansion rates of 0.16, 0.38, and 0.58 m/year. We modeled thermal development of the talik using boundary conditions based on field data from the lake, surrounding permafrost and a borehole, independent of the transient electromagnetics. A talik depth of 91 m was determined from analysis of the transient electromagnetic surveys. Using a lake initiation age of 1400 years before present and available subsurface properties the results from thermal modeling of the lake center arrived at a best estimate talk depth of 80 m, which is on the same order of magnitude as the results from the transient electromagnetic survey. Our approach has provided a noninvasive estimate of talik geometry suitable for comparable settings throughout circum‐Arctic coastal lowland regions.
A Numerical Study of Gravity Wave Propagation Characteristics in the Stratospheric Thermal Duct

Published: October 2018

AbstractWe developed a fully nonlinear, two‐dimensional, numerical model to simulate the long horizontal distance propagations of atmospheric gravity waves in a stratospheric thermal duct. The numerical results show that after the wind disturbance excited by the initial wave forcing enters the duct completely, symmetric and antisymmetric modes can be identified in the horizontal direction. The frequency‐wave number spectrum indicates that various modes with different spatial structures can exist simultaneously in the duct. The primary parameters (horizontal wavelength, vertical wavelength and wave frequency) of the ducted wave packets in a given thermal duct are mainly determined by the horizontal wavelength of the initial wave forcing. The mean ratio of the upward propagating energy to the downward propagating energy in the thermal duct was regarded as an approximation of the power standing wave ratio (PSWR). The time variation of PSWR indicates that the standing wave was formed with the propagation of the ducted waves. During the gravity waves ducted propagation, most wave energy is restricted to the ducting region and dissipates slowly with time. The higher the wave frequency (or the shorter the horizontal wavelength) of the initial wave forcing, the slower the wave energy dissipates.
