Authors: Ruhaena Lisnawati 
Published: November 2016

This research aimed to develop a model of literacy stimulation for preschool children in order to meet their needs and to overcome parents’ problems in stimulating literacy in their children at home. The data of children’s needs and parents’ problem were obtained from questionnaires and focus group discussion. The questionnaires were filled by 75 mothers whose children aged 3-5 years old in Surakarta. Then, 26 of them attended focused group discussion. The data obtained showed that there was a problem in these children’s early literacy development. Most of them were lack of interest in literacy activities and most of the parents were unable to attract their children’s attention and interest. The problem faced by the parents was the lack of skill in selecting and doing literacy activities in accordance with their children’s needs. A multisensory model was designed to improve pre-school children’s interest in early development of literacy and to increase parents’ skill in stimulating their children’s interest.

EVALUASI PRODUKTIVITAS TANAMAN KARET DENGAN SISTEM TANAM GANDA PADA SKALA KOMERSIAL
Authors: Siagian Nurhawaty , Siregar Tumpal H. S. 
Published: November 2016

Salah satu faktor penyebab tidak tercapainya produktivitas yang optimal (yaitu 35-38 ton karet kering/ha/siklus tanam) di perkebunan karet adalah akibat penurunan populasi/jumlah tanaman yang disadap per hektar. Balai Penelitian Sungei Putih pada tahun 1984 mengajukan sistem tanam ganda, bertujuan untuk meningkatkan produktivitas lahan perkebunan karet melalui peningkatan populasi per ha. Selain menghasilkan karet, diproyeksikan sistem tanam ganda juga mampu menghasilkan kayu dalam jumlah yang relatif tinggi. Tulisan ini menyajikan evaluasi terhadap areal yang mengelola sistem tanam ganda pada salah satu kebun karet PTPN di Sumatera Utara. Dua sistem tanam/populasi yang diterapkan yaitu sistem tanam tunggal dan sistim tanam ganda 3. Hasil evaluasi menunjukkan bahwa meskipun produktivitas tanaman dalam g/p/s pada sistem tanam ganda masih 67,62% dari produktivitas tanaman pada sistem tanam tunggal, tetapi dengan jumlah pohon per ancak yang lebih tinggi, produktivitas penyadap (kg/penyadap/hari sadap) hampir setara. Pada sistem tanam ganda produktivitas per hektar adalah 2.415 kg/ha, sementara pada sistem tanam tunggal hanya 1.697 kg/ha. Volume kayu per hektar pada tanaman ganda 3 mencapai 264,5 m3/ha atau 91,7% lebih tinggi dibandingkan dengan volume kayu per hektar pada sistem tanaman tunggal. Sistem tanam ganda 3 merupakan alternatif yang patut dikembangkan sebagai jawaban terhadap kebutuhan ekologi dan semakin meningkatnya permintaan kayu.

Published: November 2016

PREMISE OF THE STUDY:Studies of natural genetic variation can elucidate the genetic basis of phenotypic variation and the past population structure of species. Our study species, Taxodium distichum, is a unique conifer that inhabits the flood plains and swamps of North America. Morphological and ecological differences in two varieties, T. distichum var. distichum (bald cypress) and T. distichum var. imbricarium (pond cypress), are well known, but little is known about the level of genetic differentiation between the varieties and the demographic history of local populations.METHODS:We analyzed nucleotide polymorphisms at 47 nuclear loci from 96 individuals collected from the Mississippi River Alluvial Valley (MRAV), and Gulf Coastal populations in Texas, Louisiana, and Florida using high‐throughput DNA sequencing. Standard population genetic statistics were calculated, and demographic parameters were estimated using a composite‐likelihood approach.KEY RESULTS:Taxodium distichum in North America can be divided into at least three genetic groups, bald cypress in the MRAV and Texas, bald cypress in Florida, and pond cypress in Florida. The levels of genetic differentiation among the groups were low but significant. Several loci showed the signatures of positive selection, which might be responsible for local adaptation or varietal differentiation.CONCLUSIONS:Bald cypress was genetically differentiated into two geographical groups, and the boundary was located between the MRAV and Florida. This differentiation could be explained by population expansion from east to west. Despite the overlap of the two varieties’ ranges, they were genetically differentiated in Florida. The estimated demographic parameters suggested that pond cypress split from bald cypress during the late Miocene.

Published: November 2016

ABSTRACT
A galaxy group catalog is constructed from the 2MASS Redshift Survey (2MRS) with the use of a halo-based group finder. The halo mass associated with a group is estimated using a “GAP” method based on the luminosity of the central galaxy and its gap with other member galaxies. Tests using mock samples show that this method is reliable, particularly for poor systems containing only a few members. On average, 80% of all the groups have completeness

, and about 65% of the groups have zero contamination. Halo masses are estimated with a typical uncertainty of

. The application of the group finder to the 2MRS gives 29,904 groups from a total of 43,246 galaxies at

, with 5286 groups having two or more members. Some basic properties of this group catalog is presented, and comparisons are made with other group catalogs in overlap regions. With a depth to

and uniformly covering about 91% of the whole sky, this group catalog provides a useful database to study galaxies in the local cosmic web, and to reconstruct the mass distribution in the local universe.
THE IMPRINT OF EXOPLANET FORMATION HISTORY ON OBSERVABLE PRESENT-DAY SPECTRA OF HOT JUPITERS

Published: November 2016

ABSTRACT
The composition of a planet’s atmosphere is determined by its formation, evolution, and present-day insolation. A planet’s spectrum therefore may hold clues on its origins. We present a “chain” of models, linking the formation of a planet to its observable present-day spectrum. The chain links include (1) the planet’s formation and migration, (2) its long-term thermodynamic evolution, (3) a variety of disk chemistry models, (4) a non-gray atmospheric model, and (5) a radiometric model to obtain simulated spectroscopic observations with James Webb Space Telescope and ARIEL. In our standard chemistry model the inner disk is depleted in refractory carbon as in the Solar System and in white dwarfs polluted by extrasolar planetesimals. Our main findings are: (1) envelope enrichment by planetesimal impacts during formation dominates the final planetary atmospheric composition of hot Jupiters. We investigate two, under this finding, prototypical formation pathways: a formation inside or outside the water iceline, called “dry” and “wet” planets, respectively. (2) Both the “dry” and “wet” planets are oxygen-rich (C/O < 1) due to the oxygen-rich nature of the solid building blocks. The “dry” planet’s C/O ratio is <0.2 for standard carbon depletion, while the “wet” planet has typical C/O values between 0.1 and 0.5 depending mainly on the clathrate formation efficiency. Only non-standard disk chemistries without carbon depletion lead to carbon-rich C/O ratios >1 for the “dry” planet. (3) While we consistently find C/O ratios <1, they still vary significantly. To link a formation history to a specific C/O, a better understanding of the disk chemistry is thus needed.

Published: November 2016

ABSTRACT
Previous detections of methyl and ethyl formate make other small substituted formates potential candidates for observation in the interstellar medium. Among them, vinyl formate is one of the simplest unsaturated carboxylic ester. The aim of this work is to provide direct experimental frequencies of the ground vibrational state of vinyl formate in a large spectral range for astrophysical use. The room-temperature rotational spectrum of vinyl formate has been measured from 80 to 360 GHz and analyzed in terms of Watson’s semirigid rotor Hamiltonian. Two thousand six hundred transitions within J = 3–88 and K

a
= 0–28 were assigned to the most stable conformer of vinyl formate and a new set of spectroscopic constants was accurately determined. Spectral features of vinyl formate were then searched for in Orion KL, Sgr B2(N), B1-b, and TMC-1 molecular clouds. Upper limits to the column density of vinyl formate are provided.

Published: November 2016

ABSTRACT
Massive stars are key players in the evolution of galaxies, yet their formation pathway remains unclear. In this work, we use data from several galaxy-wide surveys to build an unbiased data set of ∼600 massive young stellar objects, ∼200 giant molecular clouds (GMCs), and ∼100 young (<10 Myr) optical stellar clusters (SCs) in the Large Magellanic Cloud. We employ this data to quantitatively study the location and clustering of massive star formation and its relation to the internal structure of GMCs. We reveal that massive stars do not typically form at the highest column densities nor centers of their parent GMCs at the ∼6 pc resolution of our observations. Massive star formation clusters over multiple generations and on size scales much smaller than the size of the parent GMC. We find that massive star formation is significantly boosted in clouds near SCs. However, whether a cloud is associated with an SC does not depend on either the cloud’s mass or global surface density. These results reveal a connection between different generations of massive stars on timescales up to 10 Myr. We compare our work with Galactic studies and discuss our findings in terms of GMC collapse, triggered star formation, and a potential dichotomy between low- and high-mass star formation.
OCEAN g-MODES ON TRANSIENT NEUTRON STARS
Authors: Deibel Alex 
Published: November 2016

ABSTRACT
The neutron star ocean is a plasma of ions and electrons that extends from the base of the neutron star’s envelope to a depth where the plasma crystallizes into a solid crust. During an accretion outburst in an X-ray transient, material accumulates in the envelope of the neutron star primary. This accumulation compresses the neutron star’s outer layers and induces nuclear reactions in the ocean and crust. Accretion-driven heating raises the ocean’s temperature and increases the frequencies of

-modes in the ocean; when accretion halts, the ocean cools and ocean

-mode frequencies decrease. If the observed low-frequency quasi-periodic oscillations on accreting neutron stars are

-modes in the ocean, the observed quasi-periodic oscillation frequencies will increase during the outburst—reaching a maximum when the ocean temperature reaches steady state—and subsequently decrease during quiescence. For time-averaged accretion rates during outbursts between

the predicted

-mode fundamental n = 1 l = 2 frequency is between ≈3–7 Hz for slowly rotating neutron stars. Accreting neutron stars that require extra shallow heating, such as the Z-sources MAXI J0556-332, MXB 1659-29, and XTE J1701-462, have predicted

-mode fundamental frequencies between ≈3–16 HZ. Therefore, observations of low-frequency quasi-periodic oscillations between

in these sources, or in other transients that require shallow heating, will support a

-mode origin for the observed quasi-periodic oscillations.
A DEEP X-RAY VIEW OF THE BARE AGN ARK 120. II. EVIDENCE FOR Fe K EMISSION TRANSIENTS

Published: November 2016

ABSTRACT
We report on the results from a large observational campaign on the bare Seyfert galaxy Ark 120, jointly carried out in 2014 with XMM-Newton, Chandra, and NuSTAR. The fortunate line of sight to this source, devoid of any significant absorbing material, provides an incomparably clean view to the nuclear regions of an active galaxy. Here we focus on the analysis of the iron fluorescence features, which form a composite emission pattern in the 6–7 keV band. The prominent Kα line from neutral iron at 6.4 keV is resolved in the Chandra High-Energy Transmission Grating spectrum to a full-width at half maximum of

km s−1, consistent with an origin from the optical broad-line region. Excess components are detected on both sides of the narrow Kα line: the red one (6.0–6.3 keV) clearly varies in strength in about one year, and hints at the presence of a broad, mildly asymmetric line from the accretion disk; the blue one (6.5–7.0 keV), instead, is likely a blend of different contributions, and appears to be constant when integrated over long enough exposures. However, the Fe K excess emission map computed over the 7.5 days of the XMM-Newton monitoring shows that both the red and blue features are actually highly variable on timescales of ∼10–15 hr, suggesting that they might arise from short-lived hotspots on the disk surface, located within a few tens of gravitational radii from the central supermassive black hole and possibly illuminated by magnetic reconnection events. Any alternative explanation would still require a highly dynamic, inhomogeneous disk/coronal system, involving clumpiness and/or instability.
PECULIAR TRANSVERSE VELOCITIES OF GALAXIES FROM QUASAR MICROLENSING. TENTATIVE ESTIMATE OF THE PECULIAR VELOCITY DISPERSION AT Z ∼ 0.5

Published: November 2016

ABSTRACT
We propose to use the flux variability of lensed quasar images induced by gravitational microlensing to measure the transverse peculiar velocity of lens galaxies over a wide range of redshift. Microlensing variability is caused by the motions of the observer, the lens galaxy (including the motion of the stars within the galaxy), and the source. Hence, its frequency is directly related to the galaxy’s transverse peculiar velocity. The idea is to count time-event rates (e.g., peak or caustic crossing rates) in the observed microlensing light curves of lensed quasars that can be compared with model predictions for different values of the transverse peculiar velocity. To compensate for the large timescale of microlensing variability, we propose to count and model the number of events in an ensemble of gravitational lenses. We develop the methodology to achieve this goal and apply it to an ensemble of 17 lensed quasar systems. In spite of the shortcomings of the available data, we have obtained tentative estimates of the peculiar velocity dispersion of lens galaxies at z ∼ 0.5,

. Scaling at zero redshift, we derive

, consistent with peculiar motions of nearby galaxies and with recent N-body nonlinear reconstructions of the Local Universe based on ΛCDM. We analyze the different sources of uncertainty of the method and find that for the present ensemble of 17 lensed systems the error is dominated by Poisson noise, but that for larger ensembles the impact of the uncertainty on the average stellar mass may be significant.
