Encuentros, narrativas y experiencias con jóvenes desvinculados del conflicto armado Colombiano
Authors: Marín Aponte Lucas 
Published: February 2019

El presente texto nos aproxima a la compresión de experiencias y desafíos que viven los jóvenes desvinculados de diferentes grupos armados, luego de egresar de los programas de atención a víctimas, en su proceso de reintegración a la vida civil. A través de diversos encuentros, se propiciaron espacios de diálogos que permitieron conocer sus testimonios, con el objetivo de implementar estrategias pedagógicas para atender estas poblaciones, y ahondar en nuestra realidad nacional. El reclutamiento forzado de menores, es un fenómeno social de impacto internacional que ha motivado múltiples estudios en especial desde las ciencias sociales, este fenómeno se presenta con mayor frecuencia en zonas rurales marginadas por el Estado, dominadas por estados paralelos o repúblicas independientes, dedicadas a actividades ilícitas. Hemos visto la necesidad de promover la creación de redes de apoyo institucionales y comunitarias que fortalezcan dichos procesos de reinserción ante un eventual acuerdo de paz en Colombia.

The Legality of Oil & Gas Production Sharing Contract Gross Split Scheme
Authors: Sugiyartomo Fakharsyah Hanif 
Published: February 2019

As an oil producing nation, Indonesia embodied its authority to manage its oil resources through article 33 paragraphs 3 of The Republic of Indonesia Constitution 1945. Regarding the article, this means that the state has the authority to manage Indonesian natural resources, directly or indirectly, through other public and/or private institutions and the profit of such activity shall be for the benefit of the people. This granted the state to appoint other institution, including a National/International Oil Company (NOC/IOC), to manage the exploration and production of oil, as that particular activity is regarded as a high risk and high capital business. In order to do so, according to Law no. 22 2001, the state may appoint a NOC/IOC through a production sharing contract. In this research, it is founded that the regulation that governed a production sharing contract with the gross split mechanism—Ministry of Energy and Mineral Resources Regulation No. 8 2017 jo. Ministry of Energy and Mineral Resources No. 52 2017—does not have a strong legal basis. In overall, the management of oil and gas through the gross split mechanism does not gives a maximum benefit for the state, and does not attract the IOC/NOC interest to explore and produce oil and gas in Indonesia. Therefore, in this paper, the reviewing of oil and gas management through a gross split mechanism is recommended.

Indonesia, as the second longest coastline country in the world, contain a huge coastal area need to be managed. One way to manage coastal area is using monitoring systems, yet none of them has been effectively implemented in Indonesia. This research attempts to develop monitoring system using indicators. There were 105 indicators that chosen from references. Each of the indicators were filtered by scoring method and then be processed using PLS-SEM resulting 9 indicators and sustainability development monitoring model. Coastal Area of North Jakarta has been chosen as area to implementing the model since that area are dynamics and growing rapidly. Based on the model, coastal area of North Jakarta has good economic condition (62.2%), medium social condition (46.7%), and bad natural environment condition (38%). Sustainable development seems quite implemented in this area since the balance of Economic-Social-Natural Environment was on the medium and balanced category. By using GIS can be seen that the development that occurred in west side study area are better than middle or east side.

LAND USE CONVERSION: EVALUATION AND STRATEGIC ACTIONS
Authors: Nainggolan Ruth Roselin 
Published: February 2019

The conversion of agricultural land in Sumedang of the year 2005-2014 reached 317 hectares. The land generally converted into housing, office buildings and public facilities. This study aims to conduct a comprenhensive evaluation of the factors affecting changes in land use, analyze the impact of the changes and develop management strategies. This research was conducted with a qualitative approach located in Sumedang District, West Java Province. Sampling was done by multistage random sampling. The first step is selection of the sample subdistricts purposively with consideration of subdistricts that convert of land use at most, they are: Sumedang Selatan, Jatinangor and Jatigede. The second step sample selection by simple random to residents who do changes their agricultural land use. The data obtained from questionnaires, interviews,observations, study of documents and mass media. Working method is based on a modification of the stages of strategic planning for the company. Formulation of the strategy carried out through three phases: phase determination of the key internal and external factors, phase matching using the SWOT matrix, as well as the decision phase using QSPM matrix. The resulting strategy is implemented in a more technical work steps. The results showed the factors that affect farmers convert agricultural land is decreasing productivity of the land, accretion of family members, the right of inheritance of land, high land prices, construction of public facilities and government policy. The most dominant factor affecting is different in each district. The impact of changes in land use in general is the opening of new agricultural land by cutting down forests, decline in rice productivity and the emergence of new unemployment and alteration or loss of livelihood. From the SWOT analysis matrix, obtained three possible strategic options. First, a policy review of spatial and territories; second, to encourage farmers to maintain agricultural land by providing agricultural inputs and extension the use of organic materials to restore soil fertility and the third private land use change should be governed by strict licensing mechanism.
ON DIGITAL H-GROUPS

Published: February 2019

In this paper, specific properties of digital H-spaces and digital H-groups are studied. It is shown that there is a contravariant functor from the homotopy category of the pointed digital images to the category of groups and homomorphisms. Then it is proven that a pointed digital image having the same digital homotopy type as a digital H-group is itself a digital H-group.
An Easy Algorithm to Generate Colored Noise Sequences
Authors: Xu Chang 
Published: February 2019

Abstract
The need for accurate and efficient simulation of the noise background arises in statistical significance tests for periodic signals buried in colored noise. This paper discusses techniques for generating colored-noise sequences which simulate processes with a given spectral density. Matlab routines based on the fast fractional difference algorithm are presented. These routines can create various stochastic models (e.g., first-order autoregressive (AR(1)), power law (PL), autoregressive fractionally integrated moving average ((1, d, 0)), and generalized Gauss Markov (GGM)) that serve as possible candidate null hypotheses to test against in various scenarios. Allan variance and power spectral density (PSD) show that our algorithms are accurate and efficient, and can be easily implemented for stationary noise models and non-stationary PLs with spectral indices up to 2. Our algorithms can also be extended to produce a non-stationary PL with a range-limited steeper PSD (spectral indices up to about 4) using a GGM approximation with a proper break frequency. The red-noise leakage effect on the periodogram is further discussed. The result shows that our GGM approximation has a potential for alleviating the red-noise leakage in the PSD estimates. The Timmer & Koenig procedure is also included for comparison.

Published: February 2019

Abstract
The field of asteroseismology has enjoyed a large swath of data coming from recent missions (e.g., CoRoT, Kepler, K2). This wealth of new data has allowed the field to expand beyond the previous limitation of a few extremely bright and evolved stars. Asteroseismology relies on accurate surface measurements for boundary conditions, but the predicted physical parameters in the Kepler Input Catalog (KIC) are unreliable for hot stars. We present stellar parameters of 25 candidate pulsating B-star candidates in the Kepler field. We use blue optical spectra to measure the projected rotational velocity (

), effective temperature (T
eff), and surface gravity (

) using TLUSTY and Kurucz ATLAS9 model atmospheres. We find a large discrepancy between our spectroscopically derived parameters and those derived from photometry in the KIC and Gaia Data Release 2 (DR2). Using spectral energy distributions, we also measure the radii of these stars and later calculate the luminosities and masses. We find the extinctions (A

V
) of these stars to be consistent with zero, which is expected for stars of high Galactic latitude.

Published: February 2019

Abstract
Magnetic flux ropes (MFRs), as the most probable core structure of solar eruptive activity, remain mysterious on their origination, magnetic environment, and erupting mechanisms. Here, we newly identify a large-scale hot channel MFR, named “MFR3”, that connects an anti-Hale active region (AR) 11429 and a normal AR 11430 on 2012 March 7 based on multi-wavelength observations. An oscillation is first detected at the top of MFR3 during 00:10–00:30 UT as triggered by an X5.4 flare-related eruption of an MFR (named “MFR1” here) in AR 11429. Then, after a quiet period of ∼20 minutes at around 00:52 UT, external magnetic reconnection (EMR) occurred above MFR3 manifested by not only bidirectional outflow in extreme ultraviolet images, but also microwave quasi-periodic pulsation in broadband radio spectral observations for the first time. With the occurrence of EMR, the large-scale MFR3 quickly erupted at 01:01 UT and triggered an X1.3 flare, which is related to the eruption of the other MFR (named “MFR2” here) in AR 11429 at 01:05 UT. The erupting MFR3 and MFR2 appeared successively in the same associated halo coronal mass ejection (CME) as two different core structures. The identification of the large-scale MFR3 between two separated ARs and its complex activity may shed new light on our understanding of the initiation mechanism of a CME. Further work should lay emphasis on how a large-scale MFR3 forms in the solar atmosphere.
Super-Eddington Accretion onto the Galactic Ultraluminous X-Ray Pulsar Swift J0243.6+6124

Abstract
We report on the spectral behavior of the first Galactic ultraluminous X-ray pulsar Swift J0243.6+6124 with NuSTAR observations during its 2017–2018 outburst. At sub-Eddington levels, the source spectrum is characterized by three emission components: from the accretion column, the hot spot, and a broad iron line emission region. When the source is above the Eddington limit, the hot spot temperature increases and the spectrum features two more blackbody components. One blackbody component has a radius of 10–20 km and likely originate from the top of the accretion column. The other one saturates at a blackbody luminosity of (1–2) × 1038 erg s−1, coincident with the Eddington limit of a neutron star. This is consistent with the scenario that super-Eddington accretion onto compact objects will power optically thick outflows and indicates an accretion rate 60–80 times the critical value. This suggests that super-Eddington accretion onto magnetized systems can also power massive winds. At super-Eddington levels, the iron line becomes more significant and blueshifted, and is argued to be associated with the ultrafast wind in the central funnel or jets. This source, if located in external galaxies, will appear like other ultraluminous pulsars.
Fornax: A Flexible Code for Multiphysics Astrophysical Simulations

Published: February 2019

Abstract
This paper describes the design and implementation of our new multigroup, multidimensional radiation hydrodynamics code Fornax and provides a suite of code tests to validate its application in a wide range of physical regimes. Instead of focusing exclusively on tests of neutrino radiation hydrodynamics relevant to the core-collapse supernova problem for which Fornax is primarily intended, we present here classical and rigorous demonstrations of code performance relevant to a broad range of multidimensional hydrodynamic and multigroup radiation hydrodynamic problems. Our code solves the comoving-frame radiation moment equations using the M1 closure, utilizes conservative high-order reconstruction, employs semi-explicit matter and radiation transport via a high-order time stepping scheme, and is suitable for application to a wide range of astrophysical problems. To this end, we first describe the philosophy, algorithms, and methodologies of Fornax and then perform numerous stringent code tests that collectively and vigorously exercise the code, demonstrate the excellent numerical fidelity with which it captures the many physical effects of radiation hydrodynamics, and show excellent strong scaling well above 100,000 MPI tasks.

Abstract
A class of asteroids, called large super-fast rotators (large SFRs), have rotation periods shorter than 2 hr and diameters larger than ∼0.3 km. They pose challenges to the usual interior rubble-pile structure unless a relatively high bulk density is assumed. So far, only six large SFRs have been found. Therefore, we present a survey of asteroid rotation periods using the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) 1 telescope during 2016 October 26–31 to search for more large SFRs and to study their properties. A total of 876 reliable rotation periods are measured, among which seven are large SFRs, thereby increasing the inventory of known large SFRs. These seven newly discovered large SFRs have diverse colors and locations in the main asteroid belt, suggesting that the taxonomic tendency and the location preference in the inner main belt of the six previously known large SFRs could be a bias due to various observational limits. Interestingly, five out of the seven newly discovered large SFRs are mid main-belt asteroids (MBAs). Considering the rare discovery rates of large SFR in the previously similar surveys and the survey condition in this work, the chance of detecting a large SFR in the inner main belt seems to be relatively low. This probably suggests that the inner main belt harbors fewer large SFRs than the mid main belt. From our survey, we also found a drop in the number appearing at f > 5 rev day−1 on the spin-rate distribution for the outer MBAs of D < 3 km, which was reported for the inner and mid main belt by Chang et al.
Théologie stoïcienne et allégorie dans l’Abrégé de Cornutus : une rationalisation totale du mythe ?
Authors: Pià Comella Jordi 
Published: February 2019

D’après les épicuriens et les platoniciens, l’allégorie stoïcienne réduit les dieux mythologiques à de simples réalités physiques, risquant ainsi de saper les fondements du polythéisme. Le présent article se propose de revenir sur cette perception schématique à partir du seul témoignage quasiment intact qui nous reste de l’allégorèse stoïcienne, à savoir l’Abrégé de Cornutus. Selon nous, l’allégorie des mythes telle que la pratique Cornutus n’est pas seulement l’explicitation rationnelle de vérités exprimées intuitivement par les Anciens : elle est ce discours qui, en empruntant au mythe son symbolisme, son pouvoir évocateur et sa part d’irrationnel, parvient, mieux que la seule démonstration théologique du philosophe, à rendre compte de la nature divine et du monde dans toute leur complexité.
Constructions mixtes en terre et bois

Published: February 2019

Lors des travaux concernant le contournement routier nord de Dijon, un habitat stratifié du ve siècle avant notre ère a été mis au jour sur près de 8000 m² dans une combe bordant la vallée de l’Ouche. L’exceptionnelle conservation des vestiges (niveaux de sols en terre battue, foyers, seuils des maisons…) s’explique par l’érosion des pentes qui a recouvert rapidement le site sous presque 1,50 m de colluvions, le préservant des labours et de toute autre destruction. Au centre de ce petit village, constitué de quatorze maisons à absides réparties régulièrement dans la combe, se trouvait une forge dans laquelle étaient fabriqués des fibules, des agrafes de ceinture et du mobilier de toilettes (pince à épiler, scalptorium…).
