Authors: Soraya Emma , Wardhana Wahyu , Sadono Ronggo 
Published: November 2016

Kemampuan ekosistem hutan di wilayah gunungapi pasca erupsi dapat kembali berfungsi seperti sebelumnya sangat dipengaruhi oleh resiliensi atau daya lentur/lembam ekosistem tersebut. Resiliensi suatu ekosistem dalam studi ini didefinisikan sebagai kemampuan ekosistem untuk bangkit kembali setelah guncangan/gangguan. Tujuan penelitian ini adalah untuk memodelkan sebaran resiliensi spasial ekosistem hutan di kawasan Taman Nasional Gunung Merapi (TNGM) lima tahun pasca erupsi dan intervensi restorasi. Analisis dilakukan dengan pendekatan penginderaan jauh multi temporal dan analisis spasial menggunakan sistem informasi geografis untuk menggambarkan perubahan kondisi ekosistem gunungapi sebelum dan pasca erupsi dan kegiatan restorasi. Hasil pemodelan menunjukkan bahwa setelah lima tahun pasca erupsi, telah terjadi transisi resiliensi/perbaikan ekosistem dari lahan terbuka ke lahan dengan tutupan vegetasi berupa rumput, semak belukar, dan hutan sekunder. Transisi resiliensi ini terjadi baik secara suksesi alami maupun campur tangan manusia dalam bentuk tindakan restorasi. Salah satu catatan hasil dari penelitian ini antara lain adalah keberhasilan kegiatan restorasi untuk mengembalikan kondisi ekosistem seperti sebelum erupsi tidak selalu dapat dideteksi dalam jangka lima tahun setelah erupsi. Kata kunci: Gunungapi Merapi; multi temporal; penginderaan jauh; resiliensi spasial; sistem informasi geografis Spatial Resilience Modelling of Merapi Volcano Ecosystem Post-EruptionThe ability of volcano ecosystem to recover post an eruption to the pre eruption status is affected by its ecological resilience. Resilience of an ecosystem can be defined as the ability of an ecosystem to bounch back after (a) disturbance(s). This study aimed to model spatial resilience of Merapi volcano ecosystem within the area of National Park of Merapi Volcano (TNGM) five years post 2010 eruption and restoration intervention. Analysis was conducted using multi temporal remote sensing and spatial analysis using geographic information system to draw the changes of the ecosystem over time, particularly post eruption and restoration actions. The modelling resulted that five years post eruption, there was resilience transisition/ recovery in volcano ecosystem in TNGM post 2010 eruption. The resilience was shown by the changes from open area to vegetation covers as grass, shrubs, and secondary forests. The transitions occured in term of natural succession as well as human intervention in restoration programs. However, the success of restoration actions to recover the ecosystem to the pre eruption status was not always able to be detected within the period of five years post eruption.

<p><em>The present study aims at investigating the relationship between the extraversion level and speaking anxiety in the English as a Foreign Language (EFL) context on the one hand, and to testify the relationship between the extraversion degree and their speech fluency and speech accuracy, on the other hand. To this end, 60 advanced university students comprising 12 males and 48 females took part in the study at the quantitative phase, and 28 of them including 14 from the extraversion levels, and 14 from the introversion levels were observed on their oral performance at the qualitative phase. Based on Spearman’s Rank Order Correlation using SPSS in the quantitative section, the findings revealed a strong negative correlation between the extraversion level and public speaking anxiety on the one hand, and a strong positive correlation between the extraversion degree and speech fluency in the qualitative phase on the other hand. Speech accuracy revealed not to have any significant correlation with the extraversion degree. Indeed, extraversion-introversion seems to be one of the major personality differences that has grabbed the attention of the psycholinguists, in particular (Dornyei,2005); henceforth, it would be worthwhile to clarify the underlying characteristics of this construct to gain a more comprehensive view of this personality type indicator, respectively.</em><em></em></p>

Non sum Oedipus, sed Morus
Authors: Mitjans Frank 
Published: November 2016

Frank Mitjans is an architect who has worked in London since 1976. He was introduced to the significance of the figure of St. Thomas More by Andrés Vázquez de Prada (1923-2005), author of the biography, Sir Tomás Moro, Lord Canciller de Inglaterra (Madrid, 1962). In 1977 Vázquez de Prada invited Mitjans to visit with him the Thomas More Exhibition at the National Portrait Gallery, which stimulated his interest in representations of More, his family and his friends. Since August 2002 he has given many presentations and talks on the topography of More’s London to groups of students and other interested people in Britain, Ireland, and Sweden. Frank Mitjans, architecte qui travaille à Londres depuis 1976, fut initié au personnage de Saint Thomas More par Andrés Vázquez de Prada (1923-2003), auteur de la biographie Sir Tomás Moro, Lord Canciller de Inglaterra (Madrid, 1962). En 1977 Vázquez de Prada l’invita à l’accompagner dans sa visite de l’exposition Thomas More à la National Portrait Gallery, évènement qui aiguisa son intérêt pour les représentations de More, de sa famille et de ses amis. Depuis août 2002 il a régulièrement fait des présentations et des exposés à des groupes d’étudiants et d’autres en Grande-Bretagne, Irlande et Suède au sujet de la topographie du Londres de Thomas More. The recent exhibitions of the works of Holbein in London and Basel (2006-2007), and scholarly publications such as Holbein and England (2004), have rekindled interest in the Portrait of Thomas More and his Family, and in the late sixteenth-century versions of Holbein’s presumed lost original. The present paper analyses the differences between the sixteenth-century versions and Holbein’s 1527 composition sketch, and concludes that the sketch is a more reliable witness to Holbein’s lost painting than the later versions, as well as the only authentic witness to More’s intentions; though anything we learn from the drawing must be checked against what we know from More’s letters and writings and other biographical data. From the later versions, however, and in particular from the references to Seneca on them, we can learn about those who commissioned them and England’s peculiar historical circumstances.
Paysage et corps dans l’Utopie de Thomas More : étude à partir des textes et des gravures des premières éditions et traductions
Authors: Pierrot Claire 
Published: November 2016

Résumé Comment représenter des corps et un paysage utopiques ? Thomas More répond à cette question en proposant un paysage total, résultat du travail de l’homme sur la nature, objet chorographique par excellence, puisque l’auteur y privilégie lîle, la ville et le jardin. Loin de se réifier, le paysage utopique garde une certaine opacité par son ambivalence entre réalité et imaginaire, par les jeux de points de vue parfois contradictoires, aussi présents dans le texte et ses liminaires que dans les gravures.
Gas dynamic trap: experimental results and future prospects
Authors: Ivanov A A , Prikhodko V V 
Published: November 2016

Abstract
The gas dynamic trap (GDT) is a version of a magnetic mirror with a long mirror-to-mirror distance far exceeding the effective mean free path of ion scattering into the loss cone, with a large mirror ratio (R ∼ 100; R = B
max/B
min is the ratio of magnetic field inductions at the mirror and at the trap center) and with axial symmetry. Under these conditions, in contrast to a conventional magnetic mirror, the plasma confined in a GDT is isotropic and Maxwellian. The plasma loss rate through the ends is governed by a set of simple gas dynamic equations; hence, the name of the device. The plasma lifetime in a GDT is on the order of LR/V
Ti, where L is the mirror-to-mirror distance, and V
Ti is the ion thermal velocity. Thus, increasing both the length of the device and the mirror ratio can, in principle, make the plasma lifetime sufficient for fusion applications. This paper discusses plasma confinement and heating results from the Novosibirsk GDT facility and examines prospects for using GDTs to develop a high-flux volumetric neutron source for fusion material testing and for driving subcritical fission reactors.
Meson production processes in electron–positron collisions and tau-lepton decays within the extended Nambu – Jona-Lasinio model
Authors: Volkov M K , Arbuzov A B 
Published: November 2016

Abstract
The extended Nambu–Jona-Lasinio model is briefly described and various ways to apply it are demonstrated. Theoretical approaches to the low-energy meson production processes in colliding electron–positron beams and tau-lepton decays are reviewed. The processes considered occur via intermediate scalar, vector, and axial-vector mesons in the ground state and in the first radially excited state. The model uses the concept of spontaneous chiral symmetry breaking to describe such states. Experimental and theoretical comparisons with other phenomenological strong interaction models are presented.
AN ORIGIN OF MULTIPLE RING STRUCTURE AND HIDDEN PLANETS IN HL TAU: A UNIFIED PICTURE BY SECULAR GRAVITATIONAL INSTABILITY
Authors: Takahashi Sanemichi Z. , Inutsuka Shu-ichiro 
Published: November 2016

ABSTRACT
Recent ALMA observation has revealed multiple ring structures formed in a protoplanetary disk around HL Tau. Prior to the ALMA observation of HL Tau, theoretical analysis of secular gravitational instability (GI) described a possible formation of multiple ring structures with separations of 13 au around a radius of 100 au in protoplanetary disks under certain conditions. In this article, we reanalyze the viability of secular GI by adopting the physical values inferred from the observations. We derive the radial distributions of the most unstable wavelength and the growth timescale of secular GI and verify that secular GI can form the ring structures observed in HL Tau. When a turbulent viscosity coefficient α remains small in the inner region of the disk, secular GI grows in the whole disk. Thus, the formation of planetary mass objects should occur first in the inner region as a result of gravitational fragmentation after the nonlinear growth of secular GI. In this case, the resulting objects are expected to create gaps at r ∼ 10 au and ∼30 au. As a result, all ring structures in HL Tau can be created by secular GI. If this scenario is realized in HL Tau, the outer region corresponds to the earlier growth phase of the most unstable mode of secular GI, and the inner region corresponds to the outcome of the nonlinear growth of secular GI. Therefore, this interpretation suggests that we are possibly witnessing both the beginning and the end of planet formation in HL Tau.

ABSTRACT
We target the thermal emission spectrum of the non-transiting gas giant HD 88133 b with high-resolution near-infrared spectroscopy, by treating the planet and its host star as a spectroscopic binary. For sufficiently deep summed flux observations of the star and planet across multiple epochs, it is possible to resolve the signal of the hot gas giant’s atmosphere compared to the brighter stellar spectrum, at a level consistent with the aggregate shot noise of the full data set. To do this, we first perform a principal component analysis to remove the contribution of the Earth’s atmosphere to the observed spectra. Then, we use a cross-correlation analysis to tease out the spectra of the host star and HD 88133 b to determine its orbit and identify key sources of atmospheric opacity. In total, six epochs of Keck NIRSPEC L-band observations and three epochs of Keck NIRSPEC K-band observations of the HD 88133 system were obtained. Based on an analysis of the maximum likelihood curves calculated from the multi-epoch cross-correlation of the full data set with two atmospheric models, we report the direct detection of the emission spectrum of the non-transiting exoplanet HD 88133 b and measure a radial projection of the Keplerian orbital velocity of 40 ± 15 km s−1, a true mass of

, a nearly face-on orbital inclination of

, and an atmosphere opacity structure at high dispersion dominated by water vapor. This, combined with 11 years of radial velocity measurements of the system, provides the most up-to-date ephemeris for HD 88133.

ABSTRACT
Observations of stellar clusters have had a tremendous impact in forming our understanding of stellar evolution. The open cluster M67 has a particularly important role as a calibration benchmark for stellar evolution theory due to its near-solar composition and age. As a result, it has been observed extensively, including attempts to detect solar-like oscillations in its main sequence and red giant stars. However, any asteroseismic inference has so far remained elusive due to the difficulty in measuring these extremely low-amplitude oscillations. Here we report the first unambiguous detection of solar-like oscillations in the red giants of M67. We use data from the Kepler ecliptic mission, K2, to measure the global asteroseismic properties. We find a model-independent seismic-informed distance of 816 ± 11 pc, or

mag, an average red giant mass of

, in agreement with the dynamical mass from an eclipsing binary near the cluster turn-off, and ages of individual stars compatible with isochrone fitting. We see no evidence of strong mass loss on the red giant branch. We also determine seismic

of all the cluster giants with a typical precision of

dex. Our results generally show good agreement with independent methods and support the use of seismic scaling relations to determine global properties of red giant stars with near-solar metallicity. We further illustrate that the data are of such high quality that future work on individual mode frequencies should be possible, which would extend the scope of seismic analysis of this cluster.
COSMOLOGICAL SIMULATIONS OF EARLY BLACK HOLE FORMATION: HALO MERGERS, TIDAL DISRUPTION, AND THE CONDITIONS FOR DIRECT COLLAPSE

Published: November 2016

ABSTRACT
Gravitational collapse of a massive primordial gas cloud is thought to be a promising path for the formation of supermassive black holes in the early universe. We study conditions for the so-called direct collapse (DC) black hole formation in a fully cosmological context. We combine a semianalytic model of early galaxy formation with halo merger trees constructed from dark matter N-body simulations. We locate a total of 68 possible DC sites in a volume of

on a side. We then perform hydrodynamics simulations for 42 selected halos to study in detail the evolution of the massive clouds within them. We find only two successful cases where the gas clouds rapidly collapse to form stars. In the other cases, gravitational collapse is prevented by the tidal force exerted by a nearby massive halo, which otherwise should serve as a radiation source necessary for DC. Ram pressure stripping disturbs the cloud approaching the source. In many cases, a DC halo and its nearby light source halo merge before the onset of cloud collapse. When the DC halo is assembled through major mergers, the gas density increases rapidly to trigger gravitational instability. Based on our cosmological simulations, we conclude that the event rate of DC is an order of magnitude smaller than reported in previous studies, although the absolute rate is still poorly constrained. It is necessary to follow the dynamical evolution of a DC cloud and its nearby halo(s) in order to determine the critical radiation flux for DC.
ENERGY DISSIPATION AND LANDAU DAMPING IN TWO- AND THREE-DIMENSIONAL PLASMA TURBULENCE
Authors: Li Tak Chu , Howes Gregory G. , Klein Kristopher G. , TenBarge Jason M. 
Published: November 2016

ABSTRACT
Plasma turbulence is ubiquitous in space and astrophysical plasmas, playing an important role in plasma energization, but the physical mechanisms leading to dissipation of the turbulent energy remain to be definitively identified. Kinetic simulations in two dimensions (2D) have been extensively used to study the dissipation process. How the limitation to 2D affects energy dissipation remains unclear. This work provides a model of comparison between two- and three-dimensional (3D) plasma turbulence using gyrokinetic simulations; it also explores the dynamics of distribution functions during the dissipation process. It is found that both 2D and 3D nonlinear gyrokinetic simulations of a low-beta plasma generate electron velocity-space structures with the same characteristics as that of the linear Landau damping of Alfvén waves in a 3D linear simulation. The continual occurrence of the velocity-space structures throughout the turbulence simulations suggests that the action of Landau damping may be responsible for the turbulent energy transfer to electrons in both 2D and 3D, and makes possible the subsequent irreversible heating of the plasma through collisional smoothing of the velocity-space fluctuations. Although, in the 2D case where variation along the equilibrium magnetic field is absent, it may be expected that Landau damping is not possible, a common trigonometric factor appears in the 2D resonant denominator, leaving the resonance condition unchanged from the 3D case. The evolution of the 2D and 3D cases is qualitatively similar. However, quantitatively, the nonlinear energy cascade and subsequent dissipation is significantly slower in the 2D case.
Littérature restreinte et démocratie restreinte : retour à Victor Cousin
Authors: Viala Alain 
Published: November 2016

Résumé La littérature varie, en diachronie et en synchronie. Dès que l’on restitue leur place à ces variations, il apparaît que la conception absolue de la littérature n’est ni absolue ni éternelle, qu’elle a une histoire qui, en France, s’est dessinée au début du xix e siècle, lorsque cette conception a été théorisée par Victor Cousin (dès 1815 et dans plusieurs livres, dont ses Fragments philosophiques et Du Vrai, du Beau, du Bien ). Au même moment s’est installée une certaine conception de la démocratie. L’article propose un retour sur cette origine et avance la thèse qui pourrait s’énoncer dans la formule suivante : à démocratie restreinte, littérature restreinte.
