Authors: Natalia El Chris 
Published: February 2019

Although nowadays the new media comes to exist in the society, the conventional media like television is still be a part of Indonesian society, especially is the areas that is untouched by the internet. Television still has its own audience. Television is obliged to perform its functions in providing information, educate, entertain, control and also as a social adhesive. Children as one of television audiences always get more attention because children are the next generation who are very easily influenced by this audiovisual media. Children are the easiest figure to imitate what they see on television. Ethics in children's program broadcasted in television is important to avoid the damage of children development in both psychologically and physically.

BackgroundPromotion of physical activity in primary care has had limited success. Wearable technology presents an opportunity to support healthcare practitioners (HCPs) in providing personalised feedback to their patients.AimTo explore the differing thoughts and feelings of both HCPs and at-risk patients provided with personalised multidimensional physical activity feedback.Design & settingQualitative study with HCPs (n = 15) and patients at risk of cardiovascular disease or type 2 diabetes (n = 29), recruited from primary care.MethodHCPs and patients wore a physical activity monitor for 7 days and were subsequently shown their personalised multidimensional feedback, including sedentary time, calorie burn, short (1-minute) or long (>10-minute) bouts of moderate-to-vigorous activity during semi-structured interviews. Transcripts were analysed thematically with comparisons made between individuals of high (n = 21) and low (n = 23) physical activity levels as to their cognitive–affective responses to their data.ResultsPersonalised feedback elicited positive emotional responses for highly active participants and negative emotional responses for those with low activity. However, individuals with low activity demonstrated largely positive coping mechanisms. Some low active participants were in denial over feedback, but the majority valued it as an opportunity to think of ways to improve physical activity (cognitive reappraisal) and started forming action plans (problem-focused coping). Around half of all participants also sought to validate their feedback against peers.ConclusionPersonalised, visual feedback elicits immediate emotional and coping responses in participants of high and low physical activity levels. Further studies should explore whether multidimensional feedback could help practitioners explore diverse ways for lifestyle change with patients.
Automated Swirl Detection Algorithm (ASDA) and Its Application to Simulation and Observational Data

Published: February 2019

Abstract
Swirling motions in the solar atmosphere have been widely observed in recent years and suggested to play a key role in channeling energy from the photosphere into the corona. Here, we present a newly developed Automated Swirl Detection Algorithm (ASDA) and discuss its applications. ASDA is found to be very proficient at detecting swirls in a variety of synthetic data with various levels of noise, implying our subsequent scientific results are astute. Applying ASDA to photospheric observations with a pixel size of 39.2 km sampled by the Solar Optical Telescope on board Hinode suggests a total number of 1.62 × 105 swirls in the photosphere, with an average radius and rotating speed of ∼290 km and <1.0 km s−1, respectively. Comparisons between swirls detected in Bifrost numerical MHD simulations and both ground-based and space-borne observations suggest that (1) the spatial resolution of data plays a vital role in the total number and radii of swirls detected, and (2) noise introduced by seeing effects could decrease the detection rate of swirls, but has no significant influences in determining their inferred properties. All results have shown that there is no significant difference in the analyzed properties between counterclockwise or clockwise rotating swirls. About 70% of swirls are located in intergranular lanes. Most of the swirls have lifetimes of less than twice the cadences, meaning future research should aim to use data with much higher cadences than 6 s. In the conclusions, we propose some promising future research applications where ASDA may provide useful insight.

Abstract
We systematically investigate short-timescale (<10 day rest-frame) C iv broad absorption-line (BAL) variability to constrain quasar-wind properties and provide insights into BAL-variability mechanisms in quasars. We employ data taken by the Sloan Digital Sky Survey Reverberation Mapping project, as the rapid cadence of these observations provides a novel opportunity to probe BAL variability on shorter rest-frame timescales than have previously been explored. In a sample of 27 quasars with a median of 58 spectral epochs per quasar, we have identified 15 quasars (

%), 19 of 37 C iv BAL troughs (

%), and 54 of 1460 epoch pairs (3.7% ± 0.5%) that exhibit significant C iv BAL equivalent-width variability on timescales of less than 10 days in the quasar rest frame. These frequencies indicate that such variability is common among quasars and BALs, though somewhat rare among epoch pairs. Thus, models describing BALs and their behavior must account for variability on timescales down to less than a day in the quasar rest frame. We also examine a variety of spectral characteristics and find that, in some cases, BAL variability is best described by ionization-state changes, while other cases are more consistent with changes in covering fraction or column density. We adopt a simple model to constrain the density and radial distance of two outflows appearing to vary by ionization-state changes, yielding outflow density lower limits consistent with previous work.
Thermal Emission and Magnetic Beaming in the Radio and X-Ray Mode-switching PSR B0943+10

Published: February 2019

Abstract
PSR B0943+10 is a mode-switching radio pulsar characterized by two emission modes with different radio and X-ray properties. Previous studies, based on simple combinations of blackbody and power-law models, showed that its X-ray flux can be decomposed in a pulsed thermal plus an unpulsed nonthermal components. However, if PSR B0943+10 is a nearly aligned rotator seen pole-on, as suggested by the radio data, it is difficult to reproduce the high observed pulsed fraction unless magnetic beaming is included. In this work, we reanalyze all of the available X-ray observations of PSR B0943+10 with simultaneous radio coverage, modeling its thermal emission with polar caps covered by a magnetized hydrogen atmosphere or with a condensed iron surface. The condensed surface model provides good fits to the spectra of both pulsar modes, but, similarly to the blackbody, it cannot reproduce the observed pulse profiles, unless an additional power law with an ad hoc modulation is added. Instead, the pulse profiles and phase-resolved spectra are well described using the hydrogen atmosphere model to describe the polar cap emission plus an unpulsed power law. For the X-ray brighter state (Q-mode) we obtain a best fit with a temperature

, an emitting radius

m, a magnetic field consistent with the value of the dipole field of 4 × 1012 G inferred from the timing parameters, and a small angle between the magnetic and spin axis, ξ = 5.° The corresponding parameters for the X-ray fainter state (B-mode) are

and R ∼ 170 m.

Abstract
In this paper, we present extensive optical and ultraviolet (UV) observations of the type Ia supernova (SN Ia) 2013gs discovered during the Tsinghua-NAOC Transient Survey. The photometric observations in the optical show that the light curves of SN 2013gs are similar to those of normal SNe Ia, with an absolute peak magnitude of M

B
= −19.25 ± 0.15 mag and a post-maximum decline rate Δm
15(B) = 1.00 ± 0.05 mag. Gehrels Swift Ultra-Violet/Optical Telescope observations indicate that SN 2013gs shows unusually strong UV emission (especially in the uvw1 band) at around the maximum light (M

uvw1 ∼ −18.9 mag). The SN is characterized by relatively weak Fe ii
iii absorptions at ∼5000 Å in the early spectra and a larger expansion velocity (v
Si ∼ 13,000 km s−1 around the maximum light) than the normal-velocity SNe Ia. We discuss the relation between the

color and some observables, including Si ii velocity, line strength of Si ii
λ6355 and Fe ii/iii lines, and Δm
15(B). Compared to other fast-expanding SNe Ia, SN 2013gs exhibits Si and Fe absorption lines with similar strength and bluer

color. We briefly discussed the origin of the observed UV dispersion of SNe Ia.
Evolution of Spiral Galaxies in Nonlocal Gravity
Authors: Roshan Mahmood , Rahvar Sohrab 
Published: February 2019

Abstract
We study the evolution of simulated disk galaxies in the context of a nonlocal theory of gravity. In this theory, the appearance of the dark matter problem in cosmology and astrophysics is a manifestation of the nonlocality of the gravitational interaction. Using high-resolution N-body simulations, we investigate the dynamical evolution of disk galaxies and compare the result with the standard dark matter viewpoint. Specifically, we construct two exponential galaxy models, one in nonlocal gravity (NLG) and the other surrounded by a Plummer dark matter halo. Both systems start from the same baryonic matter distribution, particles velocities, and random velocities and the initial Toomre’s parameter. However, although the initial conditions are the same in both models, their long-term dynamics reveal some notable differences. For example, it turns out that the bar instability happens with a higher rate in the NLG model compared with the standard case. On the other hand, at the end of the simulation, we find that bars are weaker and faster in NLG compared with the standard case.
Dense Particle Clouds in Laboratory Experiments in Context of Drafting and Streaming Instability

Published: February 2019

Abstract
The streaming instability, as an example of instabilities driven by particle feedback on a gas flow, has been proven to have a major role in controlling the formation of planetesimals. These instabilities in protoplanetary disks occur at the transition from being gas-dominated to being dust and ice particle dominated. Here, we present experiments to approach this situation in the laboratory for particles in the Knudsen flow regime. In these experiments, we observe a particle cloud trapped for about 30 s in a rotating system under Earth’s gravity. For average dust-to-gas ratios up to 0.08, particles behave like individual test particles. Their sedimentation speed is identical to that of a single free-falling particle, even in locally denser regions. However, for higher dust-to-gas ratios, the motion of particles becomes sensitive to clumping. Particles in locally denser regions now sediment faster. Their sedimentation speed then depends linearly on the overall dust-to-gas ratio. This clearly shows a transition from tracerlike behavior to collective behavior. Beyond these findings, these types of experiments can now be used as a gauge to test particle feedback models in astrophysical hydrocodes, which are currently used for numerical simulations of streaming instabilities.
Modeled Temperature-dependent Clouds with Radiative Feedback in Hot Jupiter Atmospheres
Authors: Roman Michael , Rauscher Emily 
Published: February 2019

Abstract
Using a general circulation model with newly implemented cloud modeling, we investigate how radiative feedback can self-consistently shape condensate cloud distributions, temperatures, and fluxes in a hot Jupiter atmosphere. We apply a physically motivated but simple parameterization of condensate clouds in which the temperature determines the cloud distribution, and we evaluate how different assumptions of vertical mixing and aerosol opacity affect predictions. We compare results from cases in which the aerosols are simply included in the last step of the simulation (i.e., postprocessed) to cases in which clouds and their radiative feedback are actively included throughout the duration of the simulation. When clouds and radiative feedback were actively included, cloud cover decreased at equatorial regions and increased toward the poles relative to the postprocessed solutions. The resulting phase curves also differed between the two approaches; the postprocessed cloud simulations predicted weaker day–night contrasts in emission and greater eastward shifts in the maximum emission compared to the active cloud modeling. This illustrates the importance of cloud radiative feedback and shows that postprocessing can provide inaccurate solutions when clouds are thick enough to provide significant scattering.

Abstract
We report the discovery of a quasar at z = 7.07, which was selected from the deep multi-band imaging data collected by the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey. This quasar, HSC J124353.93+010038.5, has an order of magnitude lower luminosity than do the other known quasars at z > 7. The rest-frame ultraviolet absolute magnitude is M
1450 = −24.13 ± 0.08 mag and the bolometric luminosity is

erg s−1. Its spectrum in the optical to near-infrared shows strong emission lines, and shows evidence for a fast gas outflow, as the C iv line is blueshifted and there is indication of broad absorption lines. The Mg ii-based black hole mass is

, thus indicating a moderate mass accretion rate with an Eddington ratio

. It is the first z > 7 quasar with sub-Eddington accretion, besides being the third most distant quasar known to date. The luminosity and black hole mass are comparable to, or even lower than, those measured for the majority of low-z quasars discovered by the Sloan Digital Sky Survey, and thus this quasar likely represents a z > 7 counterpart to quasars commonly observed in the low-z universe.

Introduction: Ethiopia stood third in drug-resistant tuberculosis (TB) in Africa, and more than 5,000 MDR-TB patients are reported each year. Greater than 90% of rifampicin (RIF) resistant strains are resistant to isoniazid (INH) and hence the objective of this study was to determine the prevalence and risk factors of RIF resistant MTB among presumptive TB cases at Dubti General Hospital, Afar, Ethiopia.
Methodology: In this cross-sectional study, 384 presumptive TB cases were recruited and a structured questionnaire was used to collect socio-demographic and clinical data. Sputum samples were collected and examined using X-pertMTB/RIF assay. Bivariate, multivariate logistic regressions, and fishers' exact analysis were done to assess the associations between the prevalence of TB and MDR-TB with different socio-demographic and clinical variables.
Results: In the present study, the overall prevalence of pulmonary TB was 24.5% (94/384), of this 4 (4.3%) isolates were resistant to RIF. History of anti-TB treatment (AOR = 2.4, 95% CI: 1.3-4.4 and TB contact (AOR = 3.6, 95% CI: 2.1-6.2 were significantly associated with gene X-pert MTB/RIF positive TB. Moreover, resistance to rifampicin was statistically associated with the history of TB contact with multi-drug resistant TB (P = 0.027) and khat chewer cases (P = 0.04).
Conclusions: The overall prevalence of TB and its drug-resistant were relatively higher than that of in the general population in Ethiopia. History of anti-TB treatment and TB contact were significantly associated with X-pert MTB/RIF positive MDR-TB.

Published: February 2019

Introduction: Hepatitis B virus (HBV) infection in children is a health problem worldwide. In Mexico, a high prevalence rate of HBV infection and occult HBV infection have been reported in high-risk adults and children. However, studies regarding HBV infection transmitted from HBV-infected parents to children are limited. This study aimed to determine the risk factors associated with HBV transmission of HBV from parents to children in Mexico.
Methodology: A retrospective case-control study was carried out in 24 pediatric patients with clinical HBV infection and 48 healthy controls. Bivariate and forward conditional logistic regression analysis was used to compare demographic variables, the status of HBV vaccination, and risk factors for HBV infection transmission among children and their parents.
Results: No newborns were diagnosed with HBV infection, and no significant differences were found in age (p = 0.209) or gender (p = 0.612) compared to the control group. The independent risk factor associated with HBV transmission was the presence of a parent with a history of promiscuity (OR = 30.95, 95%CI = 3.382-283.326; p = 0.002), whereas having completed the HBV vaccination schedule for their age was a protective factor against HBV infection in the children (OR = 0.245, 95%CI = 0.079-0.764; p = 0.015).
Conclusions: HBV infection in Mexican children is associated with close interpersonal contact with a parent engaged in high-risk sexual practices suggesting that the horizontal route could be the primary mode of infection. Child and adult vaccination campaigns should be reinforced to avoid HBV infection in Mexico.

Introduction: The sputum smear or the culture are the definitive diagnosis of pulmonary tuberculosis. Only a fraction of clinical patients are culture-confirmed.
Methodology: A total of 24 clinical cases (40 ± 14 years old) with positive smear and negative co-morbidity were studied. Cases were selected from 600 patients who attended the pneumology service over two years. A sputum sample was cultured in Löwenstein-Jensen medium with consequent amplification of the rrnA V2 promoter, the differentiation region 4, and the IS6110 insertion sequence of Mycobacterium tuberculosis. After the culture result, the patients were divided into negative (n = 14) or positive (n = 10) culture groups. In addition, 30 samples from healthy donors (45 ± 10 years) were studied. The numbers of CD4, CD8 and CD19 lymphocytes were determined by flow cytometry. Levels of IgA and IgG to M. tuberculosis were measured by ELISA.
Results: IgG and IgA levels were detected in patients with positive culture, while only IgA was found in patients with negative cultures. The lymphocyte populations in the two groups were similar. The presence of a pleural apical cap was found more frequently in patients with negative- (57%) than with positive cultures (10%).
Conclusions: The isotype profile in patients with positive cultures was both IgA and IgG positive, while in patients with negative culture, only IgA was found. The results will contribute to improve the diagnostic algorithm and appropriate treatment of patients with clinical tuberculosis. Further studies are needed to determine if this profile is predictive of the outcome of isolation.
