Published: May 2019

A marriage is a commitment between two people, in this case a man and woman, with material purpose to build a happy and everlasting family (household) based on Belief in the one and only God which is the first principle of Pancasila(Five Principles). Asset/property issue may arise due to marriage. The development of society’s mindset lead them to enter into a prenuptial agreement before they get married considering that both husband and wife are able to earn asset/property. Besides that, there are many other reasons to enter into a prenuptial agreement. Basically there is no mixture of wealth in marriage between husband and wife. The bconcept of shared assets originally came from customsnor traditions that developed in indonesia. This concept is then suported by islamic law and positive laws that apply in our country. Then a joint proprty agreement was made.  Prenuptial Agreement is an agreement which is made by two people (betrothed couple) before they get married. Prenuptial Agreement had been stipulated in Article 29 Law No. 1 of 1974. However, since the Constitutional Court issued the Decision No. 69/PUU-XIII/2015, Prenuptial Agreement has several modifications which are presently being pros and cons in society. The matter which is being researched in this thesis is: what is the legal consequence of a prenuptial agreement which is made after marriage and based on the Decision of Constitutional Court No. 69/PUU-XIII/2015. The approach method which is used herein is normative legal research. The law material sources are primary law material and secondary law material in form of books and Legislation. Data analyses used in this research are processing and analyzing the data qualitatively andthen descriptively drawn up. The result of this research found the differences between Prenuptial Agreement which is stipulated in Article 29 Law No. 1 of 1974 and the Prenuptial Agreement which is stipulated in the Decision of Constitutional Court No. 69/PUU-XIII/2015
“Book Nerds” United: The Reading Lives of Diverse Adolescents at the Public Library
Authors: Evans Sarah A.
Published: May 2019

This research asks the question: How does a public library contribute to the literate lives of a diverse community of adolescents? To explore this question, this article presents portraits of three young women, for whom a public library provided transformative opportunities. These portraits come from a larger ethnographic case study that examined a public library’s role in sparking and sustaining adolescent learning. Over 18 months, the author observed library activities involving youth, interviewed library staff and adolescent patrons, and led teen volunteers in a participatory research project. Data were analyzed in a constant comparative method within a sociocultural-historical framework. Through attention to the girls’ activities within the public library, two contributing elements— 1) a democratic space created by library practices, and 2), the diversity in discourse facilitated by the teen librarian—expanded the participants’ literacy practices and perspectives on reading. This article informs our understanding of diversity in adolescent literacy and highlights the practices that libraries and communities can use to foster the next generation of readers.

• Worldwide there are 6 different TBE vaccines – two from Western Europe, three from Russia and one from China. The two western European vaccines and one of the Russian vaccines have an adult and a pediatric formulation. • The products names are FSME IMMUN and FSME-IMMUN Junior; Encepur adults and Encepur children, Klesch-E-Vac, EnceVir and EnceVir Neo, Dry lyophilized TBE Moscow and Sen Tai Bao • All TBE vaccines except the one from China have similar but not identical immunization sched-ules with primary immunization (>3 doses) and regular booster vaccinations. For FSME-IMMUN, Encepur and EnceVir a rapid immunization schedules is also licensed. The Chinese vaccine is giv-en with 2 primary doses 2 weeks apart followed by annual boosters. • All vaccines induce significant immune responses. In the absence of a formal correlate of pro-tection, the presence of neutralizing antibodies is used as a surrogate marker for protection. • Recent clinical studies show long-term seropersistence of TBE antibodies after the first booster vaccination (dose 4) with the two European vaccines. • An effectiveness of approximately 99% (years 2000–2006) and 98,7% (years 2000-2011) was calculated for regularly vaccinated persons in Austria, a country with established high vaccina-tion uptake. • Whereas in Western Europe post-exposure prophylaxis with immunoglobulins was discontinued in the late 1990s, in the highly endemic regions of Russia it continues to be common practice. • Both - FSME-IMMUN and Encepur are well tolerated with a well-established safety profile. TBE-Moscow and EnceVir appear to be somewhat more reactogenic.

Bakteriler tarafından üretilen ribozomal antimikrobiyal peptidlerin bir çeşidi olan bakteriyosinler, bakterilerin %99’undan fazlası tarafından üretilmektedir. Üretici bakteri ile yakın ilişikli veya ilişkisiz bakteriyel suşların gelişimini inhibe eden bakteriyosinler, insan vücudu için zararsızdır. Patojen bakterilere karşı antibiyotiklere kıyasla yaygın olarak kullanılmaktadır. Ancak gıda güvenlik uyugulamaları ve gıda korumada potansiyel antimikrobiyal ajan olarak değerlendirilmektedir. Bu nedenle çalışmamızda Kilis yöresel peynirinden izole edilen laktik asit bakterilerinin bakteriyosin üretim kapasitesi araştırılmıştır. Bacillus cereus, Vankomisin-Dirençli Enterococci (VRE) ve Staphylococcus aureus’a karşı antibakteriyel aktiviteli hücre bağımlı bakteriyosin üreten 3 adet laktik asit bakterisi izole edilmiştir. Bakteriyosin süspansiyonlarının en etkili olduğu test bakterisi B. cereus’tur. Süspansiyonların test bakterileri üzerinde geniş bir pH aralığında (pH 4-12) aktivite gösterdiği belirlenmiş olup, 40ºC sıcaklıkta inhibitör etkinin stabilitesini koruduğu gözlenmiştir. Çeşitli kimyasal maddeler ile ön inkübasyonu takiben P2 süspansiyonunun diğer süspansiyonlara karşın aktivitesini sürdürdüğü belirlenmiştir.

Comparison of Children’s Double Dichotic Digits and SCAN-3 Competing Words Free Recall Scores
Authors: Kelley Kairn Stetler , Littenberg Benjamin
Published: May 2019

Background:Practice guidelines do not specify which test recordings are best for assessing dichotic deficit or interaural asymmetry. Dichotic Digits and SCAN-3 Competing Words Free Recall are among the most widely used dichotic tests, but it is not known if the choice of test
results in important differences in the identification of children with deficits or if they can be used interchangeably.Purpose:To determine whether two commonly used dichotic tests, SCAN-3 Competing Words Free Recall (CW) and Musiek’s Dichotic Digits (DD), agree on interaural
asymmetry and dichotic deficit in children.Research Design:CW and DD tests were administered to all participants. Each participant had a single study visit.Study Sample:Sixty volunteers aged 7‐14 years with normal hearing sensitivity participated in the study.Data Collection
and Analysis:Hearing sensitivity, CW, and DD performance were measured at a single study visit. We used Spearman’s rho (ρ) to assess associations between rank ordering of participants by each test and the kappa statistic (κ) to assess decision consistency between tests.Results:Participants
were rank-ordered similarly by CW and DD for the right ear (ρ = 0.58), left ear (ρ = 0.51), and total (ρ = 0.73) scores, but not for interaural asymmetry (ρ =0.18). They agreed no better than chance on direction of ear advantage (κ = 0.01, p = 0.93) and had poor
agreement on which children scored below cut-scores (κ = 0.22, p < 0.01). DD identified significantly more participants with deficits (n = 18) than CW (n = 3) (p < 0.001).Conclusions:Although children with high scores on one test tend to have high scores on
the other, CW and DD do not agree on ear advantage or the presence of deficit. They are not interchangeable for clinical use. Additional research is needed to determine whether either is appropriate for identifying children who would benefit from treatment for dichotic listening deficits.

Background:Individuals who have a normal pure-tone audiogram but are diagnosed with autism spectrum disorder (ASD) often exhibit poorer speech recognition and auditory processing when compared with neurotypical peers with normal pure-tone audiograms.Purpose:The purpose
of this study was to determine the efficacy and effectiveness of a 12-week auditory processing training (APT) program that was designed to address the deleterious effects of background noise and auditory processing deficits that are common among individuals diagnosed with ASD.Research Design:A
repeated measures design was used.Study Sample:The sample consisted of 15 high-functioning children and young adults who had a formal diagnosis of ASD and who were recruited from local clinics and school districts.Intervention:Participants completed the 12-week APT program consisting
of computerized dichotic training, one-on-one therapist-directed auditory training, and the use of remote microphone (RM) technology at home and in the classroom.Data Collection and Analysis:Participants completed a comprehensive test battery to assess general auditory processing skills,
speech recognition in noise, acceptance of background noise, spatial processing, binaural integration abilities, self-perceived difficulties, and observed behaviors. Testing was conducted before (n = 15), immediately after (n = 15), and 12 weeks after (n = 7) the completion of the APT program.
Paired t-tests, repeated measures analysis of variance, or nonparametric tests were used to analyze the data.Results:On average, the APT program significantly enhanced general auditory processing abilities, including binaural integration and subjective listening abilities in
the classroom. When the RM was used, significantly improved speech recognition and improved acceptance of background noise was measured relative to a condition with no technology.Conclusions:Following the APT program, the participants exhibited the greatest improvements in testing that
required binaural integration and auditory working memory. The use of the RM technology was able to address the deleterious effects of noise on speech recognition in noise and acceptance of noise levels.
On Degeneracies in Retrievals of Exoplanetary Transmission Spectra
Authors: Welbanks Luis , Madhusudhan Nikku
Published: May 2019

Accurate estimations of atmospheric properties of exoplanets from transmission spectra require the understanding of degeneracies between model parameters and observations that can resolve them. We conduct a systematic investigation of such degeneracies using a combination of detailed atmospheric retrievals and a range of model assumptions, focusing on H2-rich atmospheres. As a case study, we consider the well-studied hot Jupiter HD 209458 b. We perform extensive retrievals with models ranging from simple isothermal and isobaric atmospheres to those with full pressure–temperature profiles, inhomogeneous cloud/haze coverage, multiple-molecular species, and data in the optical–infrared wavelengths. Our study reveals four key insights. First, we find that a combination of models with minimal assumptions and broadband transmission spectra with current facilities allows precise estimates of chemical abundances. In particular, high-precision optical and infrared spectra, along with models including variable cloud coverage and prominent opacity sources, with Na and K being important in the optical, provide joint constraints on cloud/haze properties and chemical abundances. Second, we show that the degeneracy between planetary radius and its reference pressure is well characterized and has little effect on abundance estimates, contrary to previous claims using semi-analytic models. Third, collision-induced absorption due to H2–H2 and H2–He interactions plays a critical role in correctly estimating atmospheric abundances. Finally, our results highlight the inadequacy of simplified semi-analytic models with isobaric assumptions for reliable retrievals of transmission spectra. Transmission spectra obtained with current facilities such as the Hubble Space Telescope and Very Large Telescope can provide strong constraints on atmospheric abundances of exoplanets.
An Independent Analysis of the Spitzer/IRAC Phase Curves of WASP43 b

Published: May 2019

We present here a reanalysis of the Spitzer Space Telescope phase curves of the hot Jupiter WASP43 b, using the wavelet pixel-independent component analysis, a blind signal-source separation method. The data analyzed were recorded with the Infrared Array Camera and consisted of two visits at 3.6 μm, and one visit at 4.5 μm, each visit covering one transit and two eclipse events. To test the robustness of our technique we repeated the analysis on smaller portions of the phase curves, and by employing different instrument ramp models. Our reanalysis presents significant updates of the planetary parameters compared to those reported in the original phase curve study of WASP43 b. In particular, we found (1) higher nightside temperatures, (2) smaller hotspot offsets, (3) a greater consistency (∼1σ) between the two 3.6 μm visits, and (4) a greater similarity with the predictions of the atmospheric circulation models. Our parameter results are consistent within 1σ with those reported by a recent reanalysis of the same data sets. For each visit we studied the variation of the retrieved transit parameters as a function of various sets of stellar limb-darkening coefficients, finding significant degeneracy between the limb-darkening models and the analysis output. Furthermore, we performed the analysis of the single transit and eclipse events, and we examined the differences between these results with the ones obtained with the whole phase curve. Finally we provide a formula useful to optimize the trade-off between precision and duration of observations of transiting exoplanets.
Deriving Iodine-free Spectra for High-resolution Echelle Spectrographs*
Authors: Díaz Matías R. , Shectman Stephen A. , Paul Butler R. , Jenkins James S.
Published: May 2019

We describe a new method to derive clean, iodine-free spectra directly from observations acquired using high-resolution echelle spectrographs equipped with iodine cells. The main motivation to obtain iodine-free spectra is to use portions of the spectrum that are superimposed with the dense forest of iodine absorption lines, in order to retrieve lines that can be used to monitor the magnetic activity of the star, helping to validate candidate planets. In short, we provide a straightforward methodology to clean the spectra using the forward model used to derive radial velocities, the line spread function information plus the stellar spectrum without iodine to reconstruct and subtract the iodine spectrum from the observations. We show our results using observations of the star τ Ceti acquired with the Planet Finder Spectrograph (PFS), High Resolution Echelle Spectrometer (HIRES), and University College London Echelle Spectrograph (UCLES), reaching an iodine-free spectrum correction at the ∼1% rms level. We additionally discuss the limitations and further applications of the method.
Multiband Photometry of a Patroclus–Menoetius Mutual Event: Constraints on Surface Heterogeneity
Authors: Wong Ian , Brown Michael E.
Published: May 2019

We present the first complete multiband observations of a binary asteroid mutual event. We obtained high-cadence, high-signal-to-noise photometry of the UT 2018 April 9 inferior shadowing event in the Jupiter Trojan binary system Patroclus–Menoetius in four Sloan bands—g′, r′, i′, and z′. We use an eclipse light-curve model to fit for a precise mideclipse time and estimate the minimum separation of the two eclipsing components during the event. Our best-fit mideclipse time of

is 19 minutes later than the prediction of Grundy et al. The minimum separation between the center of Menoetius’s shadow and the center of Patroclus is 72.5 ± 0.7 km—slightly larger than the predicted 69.5 km. Using the derived light curves, we find no evidence for significant albedo variations or large-scale topographic features on the Earth-facing hemisphere and limb of Patroclus. We also apply the technique of eclipse mapping to place an upper bound of ∼0.15 mag on wide-scale surface color variability across Patroclus.
Alignment between Filaments and Galaxy Spins from the MaNGA Integral-field Survey

Published: May 2019

Halos and galaxies acquire their angular momentum during the collapse of the surrounding large-scale structure. This process imprints alignments between galaxy spins and nearby filaments and sheets. Low-mass halos grow by accretion onto filaments, aligning their spins with the filaments, whereas high-mass halos grow by mergers along filaments, generating spins perpendicular to the filament. We search for this alignment signal using filaments identified with the “Cosmic Web Reconstruction” algorithm applied to the Sloan Digital Sky Survey Main Galaxy Sample and galaxy spins from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) integral-field unit survey. MaNGA produces a map of the galaxy’s rotational velocity, allowing direct measurement of the galaxy’s spin direction, or unit angular momentum vector projected onto the sky. We find no evidence for alignment between galaxy spins and filament directions. We do find hints of a mass-dependent alignment signal, which is in 2σ–3σ tension with the mass-dependent alignment signal in the MassiveBlack-II and Illustris hydrodynamical simulations. However, the tension vanishes when galaxy spin is measured using the Hα emission line velocity rather than stellar velocity. Finally, in simulations we find that the mass-dependent transition from aligned to anti-aligned dark matter halo spins is not necessarily present in stellar spins: we find a stellar spin transition in Illustris but not in MassiveBlack-II, highlighting the sensitivity of spin-filament alignments to feedback prescriptions and subgrid physics.
The Dynamics of AR 12700 in Its Early Emerging Phase. I. Interchange Reconnection
Authors: Zhong Sihui , Hou Yijun , Zhang Jun
Published: May 2019

The emergence of active regions (ARs) leads to various dynamic activities. Using high-resolution and long-lasting Hα observations from the New Vacuum Solar Telescope, we report the dynamics of NOAA AR 12700 in its emerging phase on 2018 February 26 in detail. In this AR, constant interchange reconnections (IRs) between emerging fibrils and preexisting ones were detected. Driven by the flux emergence, small-scale fibrils observed in Hα wavelength continuously emerged at the center of the AR and reconnected with the ambient preexisting fibrils, forming new longer fibrils. We investigate three IR scenarios that occurred over two hours. Specially, the third scenario of reconnection resulted in the formation of longer fibrils that show pronounced rotation motion. To derive the evolution of the magnetic structure during the reconnections, we perform nonlinear force-free field extrapolations. The extrapolated three-dimensional magnetic fields clearly depict a set of almost potential emerging loops, two preexisting flux ropes at 03:00 UT before the second reconnection scenario, and a set of newly formed loops with less twist at 03:48 UT after the third reconnection scenario. All of these extrapolated structures are consistent with the fibrils detected at the Hα wavelength. The aforementioned observations and extrapolation results suggest that the constant IRs resulted in the magnetic twist being redistributed from preexisting flux ropes toward the newly formed system with longer magnetic structure and weaker twist.
SDSS-IV eBOSS Spectroscopy of X-Ray and WISE AGNs in Stripe 82X: Overview of the Demographics of X-Ray- and Mid-infrared-selected Active Galactic Nuclei

Published: May 2019

We report the results of a Sloan Digital Sky Survey IV eBOSS program to target X-ray sources and mid-infrared-selected Wide-field Infrared Survey Explorer (WISE) active galactic nucleus (AGN) candidates in a 36.8 deg2 region of Stripe 82. About half this survey (15.6 deg2) covers the largest contiguous portion of the Stripe 82 X-ray survey. This program represents the largest spectroscopic survey of AGN candidates selected solely by their WISE colors. We combine this sample with X-ray and WISE AGNs in the field identified via other sources of spectroscopy, producing a catalog of 4847 sources that is 82% complete to r ∼ 22. Based on X-ray luminosities or WISE colors, 4730 of these sources are AGNs, with a median sample redshift of z ∼ 1. About 30% of the AGNs are optically obscured (i.e., lack broad lines in their optical spectra). BPT analysis, however, indicates that 50% of the WISE AGNs at z < 0.5 have emission line ratios consistent with star-forming galaxies, so whether they are buried AGNs or star-forming galaxy contaminants is currently unclear. We find that 61% of X-ray AGNs are not selected as mid-infrared AGNs, with 22% of X-ray AGNs undetected by WISE. Most of these latter AGNs have high X-ray luminosities (L
x > 1044 erg s−1), indicating that mid-infrared selection misses a sizable fraction of the highest luminosity AGNs, as well as lower luminosity sources where AGN-heated dust is not dominating the mid-infrared emission. Conversely, ∼58% of WISE AGNs are undetected by X-rays, though we do not find that they are preferentially redder than the X-ray-detected WISE AGNs.

Despite many decades of study, the kinematics of the broad-line region of 3C 273 are still poorly understood. We report a new, high signal-to-noise, reverberation mapping campaign carried out from 2008 November to 2018 March that allows the determination of time lags between emission lines and the variable continuum with high precision. The time lag of variations in Hβ relative to those of the 5100 Å continuum is

days in the rest frame, which agrees very well with the Paschen-α region measured by the GRAVITY at The Very Large Telescope Interferometer. The time lag of the Hγ emission line is found to be nearly the same as that for Hβ. The lag of the Fe ii emission is

days, longer by a factor of ∼2 than that of the Balmer lines. The velocity-resolved lag measurements of the Hβ line show a complex structure that can be possibly explained by a rotation-dominated disk with some inflowing radial velocity in the Hβ-emitting region. Taking the virial factor of f

Published: May 2019

We present data of 10 penumbral microjets (PMJs) observed in a Hα, Ca ii 8542 Å, and Fe i 6302 Å line pair with the Swedish 1 m Solar Telescope (SST) with CRISP and Ca ii K with SST/CHROMIS in active region NOAA 12599 on 2016 October 12 at μ = 0.68. All four Stokes parameters of the Ca ii 8542 Å and Fe i 6302 Å lines were observed and a series of test pixels were inverted using the Stockholm inversion code. Our analysis revealed for the first time that PMJs are visible in Hα, where they appear as dark features with average line-of-sight (LOS) upflows of 1.1 ± 0.6 km s−1, matching the LOS velocities from the inversions. Based on the Hα observations we extend the previous average length and lifetime of PMJs to 2815 ± 530 km and 163 ± 25 s, respectively. The plane-of-sky (POS) velocities of our PMJs of up to 17 km s−1 tend to give increased velocities with distance traveled. Furthermore, two of our PMJs with significant Stokes V signal indicate that the PMJs possess an increased LOS magnetic field of up to 100 G compared to the local pre-/post- PMJ magnetic field, which propagates as quickly as the PMJs’ POS velocities. Finally, we present evidence that PMJs display an on average 1 minute gradual precursory brightening that only manifests itself in the cores of the Ca ii lines. We conclude that PMJs are not ordinary jets but likely are manifestations of heat fronts that propagate at the local Alfvén velocity.

Suprathermal ions form from interstellar gas that is first ionized into pickup ions and then accelerated to tens and hundreds of keV in energy. The resulting suprathermal ion spectra with hundreds of keV have been previously observed throughout the heliosphere; however, measurements at lower energies, around the pickup ion cutoff energy where they are accelerated from, were limited to <10 au. Here we present a statistical study of suprathermal ions in the keV to hundred keV energy range. We use the Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) instrument on the New Horizons spacecraft, which recorded observations at a wide range of heliocentric distances, and compare these measurements to charge energy mass spectrometer (CHEMS) observations on Cassini, which cruised to and remained at Saturn. We find that the power-law exponents of suprathermal ion intensity over energy are between −1 and −2, change abruptly close to discontinuities that are likely corotating merged interaction regions, correlate with the solar wind bulk speed, and show a long-term evolution on the timescale of the solar cycle. The independent measurements from New Horizons and Cassini are consistent, confirming the first fully calibrated measurements from the New Horizons/PEPSSI instrument.

Published: May 2019

We present chemical abundances for the elements carbon, sodium, and fluorine in 15 red giants of the globular cluster M4, as well as six red giants of the globular cluster ω Centauri. The chemical abundances were calculated in LTE via spectral synthesis. The spectra analyzed are high-resolution spectra obtained in the near-infrared region around 2.3 μm with the Phoenix spectrograph on the 8.1 m Gemini South Telescope, the IGRINS spectrograph on the McDonald Observatory 2.7 m Telescope, and the CRIRES spectrograph on the ESO 8.2 m Very Large Telescope. The results indicate a significant reduction in the fluorine abundances when compared to previous values from the literature for M4 and ω Centauri, due to a downward revision in the excitation potentials of the HF (1−0) R9 line used in the analysis. The fluorine abundances obtained for the M4 red giants are found to be anticorrelated with those of Na, following the typical pattern of abundance variations seen in globular clusters between distinct stellar populations. In M4, as the Na abundance increases by ∼+0.4 dex, the F abundance decreases by ∼−0.2 dex. A comparison with abundance predictions from two sets of stellar evolution models finds that the models predict somewhat less F depletion (∼−0.1 dex) for the same increase of +0.4 dex in Na.
Absolute Dimensions of the Early F-type Eclipsing Binary V506 Ophiuchi

Published: May 2019

We report extensive differential V-band photometry and high-resolution spectroscopic observations of the early F-type, 1.06-day detached eclipsing binary V506 Oph. The observations, along with times of minimum light from the literature, are used to derive a very precise ephemeris and the physical properties for the components, with the absolute masses and radii being determined to 0.7% or better. The masses are 1.4153 ± 0.0100 M
☉ and 1.4023 ± 0.0094 M
☉ for the primary and secondary, the radii are 1.725 ± 0.010 R
☉ and 1.692 ± 0.012 R
☉, and the effective temperatures are 6840 ± 150 K and 6780 ± 110 K, respectively. The orbit is circular and the stars are rotating synchronously. The accuracy of the radii and temperatures is supported by the resulting distance estimate of 564 ± 30 pc, which is in excellent agreement with the value implied by the trigonometric parallax listed in the Gaia/Data Release 2 catalog. Current stellar evolution models from the Modules for Experiments in Stellar Astrophysics (MESA) Isochrones and Stellar Tracks series for a composition of [Fe/H] = −0.04 match the properties of both stars in V506 Oph very well at an age of 1.83 Gyr and indicate they are halfway through their core hydrogen-burning phase.
An Atlas of Coronal Electron Density at 5R⊙. II. A Spherical Harmonic Method for Density Reconstruction
Authors: Morgan Huw
Published: May 2019

This is the second of a series of three papers that present a methodology with the aim of creating a set of maps of the coronal density over a period of many years. This paper describes a method for reconstructing the coronal electron density based on spherical harmonics. By assuming a radial structure to the corona at the height of interest, line-of-sight integrations can be made individually on each harmonic basis prior to determining coefficients, i.e., the computationally expensive integrations are calculated only once during initialization. This approach reduces the problem to finding the set of coefficients that best match the observed brightness using a regularized least-squares approach and is very efficient. The method is demonstrated on synthetic data created from both a simple and an intricate coronal density model. The quality of reconstruction is found to be reasonable in the presence of noise and large gaps in the data. The method is applied to both Large Angle and Spectrometric Coronagraph Experiment C2 and Solar
Terrestrial Relations Observatory Cor2 coronagraph observations from 2009 March 20, and the results from both spacecraft compared. Future work will apply the method to large data sets.

The Core Cosmology Library (CCL) provides routines to compute basic cosmological observables to a high degree of accuracy, which have been verified with an extensive suite of validation tests. Predictions are provided for many cosmological quantities, including distances, angular power spectra, correlation functions, halo bias, and the halo mass function through state-of-the-art modeling prescriptions available in the literature. Fiducial specifications for the expected galaxy distributions for the Large Synoptic Survey Telescope (LSST) are also included, together with the capability of computing redshift distributions for a user-defined photometric redshift model. A rigorous validation procedure, based on comparisons between CCL and independent software packages, allows us to establish a well-defined numerical accuracy for each predicted quantity. As a result, predictions for correlation functions of galaxy clustering, galaxy–galaxy lensing, and cosmic shear are demonstrated to be within a fraction of the expected statistical uncertainty of the observables for the models and in the range of scales of interest to LSST. CCL is an open source software package written in C, with a Python interface and publicly available at https://github.com/LSSTDESC/CCL.
SPECTRUM: Synthetic Spectral Calculations for Global Space Plasma Modeling

Published: May 2019

High-resolution spectroscopy is the most accurate tool for measuring the properties of the solar corona. However, interpreting measured line intensities and line profiles emitted by the optically thin solar corona is complicated by line-of-sight (LOS) integration, which leads to measuring weighted averages of the plasma properties along the LOS. LOS integration effects can be removed by combining CHIANTI spectral emissivities with a 3D global model of the solar corona to calculate the contribution of all structures along the LOS to the measured intensities. In this paper, we describe SPECTRUM, a postprocessing tool that can calculate the emission from the optically thin solar corona by combining 3D magnetohydrodynamic (MHD) space plasma simulation results with the CHIANTI database. Doppler-shifted, nonthermal line broadening due to low-frequency Alfvén waves and anisotropic proton and isotropic electron temperatures can be individually taken into account during calculations. Synthetic spectral calculations can then be used for model validation, for interpretation of solar observations, and for forward modeling purposes. SPECTRUM is implemented within the Space Weather Modeling Framework (SWMF) and is therefore publicly available. In this paper, we describe the SPECTRUM module and show its applications by comparing synthetic spectra using simulation data by the 3D MHD Alfvén Wave Solar Model with observations done by the Hinode/Extreme-ultraviolet Imaging Spectrometer during Carrington rotations 2063 and 2082.

Published: May 2019

Introduction: Bats have become an epidemiologically significant source of pathogenic microorganisms, such as leptospires, the causative agents of leptospirosis. However, little information exists about bats and their potential role as a reservoir of pathogenic Leptospira spp. in Colombia. The aim of this study was to evaluate the presence of pathogenic Leptospira spp. in the kidneys of bats from the Caribbean region of Colombia deposited in the collection of mammals of the Museo Javeriano de Historia Natural (MPUJ-MAMM).

Methodology: DNA was extracted from twenty-six kidney samples from a total of 13 species of bats captured in Colombia. First, 16S ribosomal RNA conventional PCR was performed to detect the presence of Leptospira spp. Then, in samples that tested positive, LipL32 PCR was performed to detect pathogenic Leptospira spp. by sequencing and phylogenetic analysis.

Results: The presence of Leptospira spp. was observed in 7/26 (26.9%) bats from the following 6 species: Carollia perspicillata, Glossophaga soricina, Dermanura phaeotis, Uroderma bilobatum, Desmodus rotundus, and Lophostoma silvicolum, and pathogenic Leptospira spp. were detected in 4/26 samples (15.4%).

Conclusions: This study suggests that bats present in the Caribbean region of Colombia could be potential reservoirs of pathogenic Leptospira spp.
