Published: September 2020

BackgroundThe aim of this study is to report on the genetic composition of Brugada syndrome (BrS) patients undergoing genetic testing in Hong Kong.MethodsPatients with suspected BrS who presented to the Hospital Authority of Hong Kong between 1997 and 2019, and underwent genetic testing, were analyzed retrospectively.ResultsA total of 65 subjects were included (n = 65, 88% male, median presenting age 42 [30–54] years old, 58% type 1 pattern). Twenty-two subjects (34%) showed abnormal genetic test results, identifying the following six novel, pathogenic or likely pathogenic mutations in SCN5A: c.674G &gt; A, c.2024-11T &gt; A, c.2042A &gt; C, c.4279G &gt; T, c.5689C &gt; T, c.429del. Twenty subjects (31%) in the cohort suffered from spontaneous ventricular tachycardia/ventricular fibrillation (VT/VF) and 18 (28%) had incident VT/VF over a median follow-up of 83 [Q1–Q3: 52–112] months. Univariate Cox regression demonstrated that syncope (hazard ratio [HR]: 4.27 [0.95–19.30]; P = 0.059), prior VT/VF (HR: 21.34 [5.74–79.31; P &lt; 0.0001) and T-wave axis (HR: 0.970 [0.944–0.998]; P = 0.036) achieved P &lt; 0.10 for predicting incident VT/VF. After multivariate adjustment, only prior VT/VF remained a significant predictor (HR: 12.39 [2.97–51.67], P = 0.001).ConclusionThis study identified novel mutations in SCN5A in a Chinese cohort of BrS patients.
Thinking Preferences and Conspiracy Belief: Intuitive Thinking and the Jumping to Conclusions-Bias as a Basis for the Belief in Conspiracy Theories
Authors: Pytlik Nico , Soll Daniel , Mehl Stephanie 
Published: September 2020

BackgroundThe belief in conspiracy theories and paranoid ideation are often treated as almost synonymous. However, there is to date no research concerning shared underlying cognitive underpinnings of belief in conspiracy theories and paranoid ideation. One potential underlying factor could be the well-known jumping to conclusion (JTC) bias, the tendency of persons with delusions to perform hasty decisions that are sometimes based on little evidence. Furthermore, a preference for a more intuitive general thinking style, as opposed to an analytical thinking style, could be an additional underlying cognitive factor of both conspiracy theories and paranoia. Thus, the aim of the present study is to investigate in a large sample of non-clinical individuals whether the JTC-bias is more pronounced in individuals who display a stronger belief in conspiracy theories and whether both are related to a more intuitive thinking preference.MethodsWe assessed the data of 519 non-clinical individuals regarding their respective approval of 20 specific conspiracy theories in an online study. Further, we assessed the JTC-bias by using a computerized variant of the beads task (fish task). Thinking preferences were measured with the Rational-Experiential Interview.ResultsSubjects who displayed the JTC-bias presented a more pronounced belief in conspiracy theories. In addition, gathering little information in the fish task before performing a decision (less draws to decision) was related to a stronger endorsement of conspiracy theories and a more intuitive thinking style (and a less analytic thinking style). Finally, a preference for intuitive thinking predicted a stronger belief in conspiracy theories in a multiple regression analysis.ConclusionsOur results demonstrate the implication of a preference for an intuitive thinking style accompanied by a propensity to faster decision-making (JTC-bias) as possible cognitive underpinnings of beliefs in conspiracy theories. Furthermore, our study is the first to confirm the notion of the JTC-bias as a reflection of the use of an intuitive thinking style.
Effectiveness of Tutorials in Improving the Academic Performance of English Language Learners
Authors: Glomo-Narzoles Danebeth , Glomo-Palermo Donna 
Published: September 2020

This study aimed to identify the effectiveness of an academic intervention, tutorial classes in particular, as perceived by the students specifically in improving their performance in their English subjects. This study made use of the Tutorial Survey questionnaire adapted from Xixi Lu, et.al. (2003). The questionnaire was distributed to the students who attended English language tutorial classes in a private university. In order to substantiate the information gathered through the questionnaire, interviews were also conducted to selected participants. Results revealed that majority of students who availed the English language tutorials were males. On the other hand, there were more working students who attended the tutorials than the non-working students. The students noted that the tutorial classes for their English subjects were very effective. They perceived the tutorial classes and the faculty tutors positively. Moreover, they were also very satisfied with the tutorial venue and time. The students do not have further recommendations to improve the university’s tutorial classes. The students also added that these tutorials have improved their listening, speaking, reading, and writing skills. For the other academic interventions, the students suggested to have peer tutoring, additional activities or enrichment materials through e-learning sites, and video tutorials for those English subjects with lab components.
Some Properties of the $k$-bonacci Words on Infinite Alphabet

Published: September 2020

The Fibonacci word $W$ on an infinite alphabet was introduced in [Zhang et al., Electronic J. Combinatorics 2017 24(2), 2-52] as a fixed point of the morphism $2i\rightarrow (2i)(2i+1)$, $(2i+1) \rightarrow (2i+2)$, $i\geq 0$.
Here, for any integer $k>2$, we define the infinite $k$-bonacci word $W^{(k)}$ on the infinite alphabet as $\varphi_k^{\omega}(0)$, where the morphism $\varphi_k$ on the alphabet $\mathbb{N}$ is defined for any $i\geq 0$ and any $0\leq j\leq k-1$, by
\begin{equation*}
\varphi_k(ki+j) = \left\{
\begin{array}{ll}
(ki)(ki+j+1) & \text{if } j = 0,\cdots ,k-2,\\
(ki+j+1)& \text{otherwise}.
\end{array} \right.
\end{equation*}
We consider the sequence of finite words $(W^{(k)}_n)_{n\geq 0}$, where $W^{(k)}_n$ is the prefix of $W^{(k)}$ whose length is the $(n+k)$-th $k$-bonacci number. We then provide a recursive formula for the number of palindromes that occur in different positions of $W^{(k)}_n$. Finally, we obtain the structure of all palindromes occurring in $W^{(k)}$ and based on this, we compute the palindrome complexity of $W^{(k)}$, for any $k>2$.
Modeling across-trial variability in the Wald drift rate parameter
Authors: Steingroever Helen , Wabersich Dominik , Wagenmakers Eric-Jan 
Published: September 2020

AbstractThe shifted-Wald model is a popular analysis tool for one-choice reaction-time tasks. In its simplest version, the shifted-Wald model assumes a constant trial-independent drift rate parameter. However, the presence of endogenous processes—fluctuation in attention and motivation, fatigue and boredom—suggest that drift rate might vary across experimental trials. Here we show how across-trial variability in drift rate can be accounted for by assuming a trial-specific drift rate parameter that is governed by a positive-valued distribution. We consider two candidate distributions: the truncated normal distribution and the gamma distribution. For the resulting distributions of first-arrival times, we derive analytical and sampling-based solutions, and implement the models in a Bayesian framework. Recovery studies and an application to a data set comprised of 1469 participants suggest that (1) both mixture distributions yield similar results; (2) all model parameters can be recovered accurately except for the drift variance parameter; (3) despite poor recovery, the presence of the drift variance parameter facilitates accurate recovery of the remaining parameters; (4) shift, threshold, and drift mean parameters are correlated.
Gas Content Regulates the Life Cycle of Star Formation and Black Hole Accretion in Galaxies
Authors: Yesuf Hassen M. , Ho Luis C. 
Published: September 2020

Abstract
Feedback from active galactic nuclei (AGNs) is expected to impact the amount of cold gas in galaxies by driving strong galactic winds, by preventing external gas inflows, or by changing the thermodynamical state of the gas. We use estimates of molecular gas mass based on dust absorption (Hα/Hβ) to study gas content of large samples of type 2 AGN host galaxies in comparison with inactive galaxies. Using sparse principal component and clustering analysis, we analyze a suite of stellar and structural parameters of ∼27,100 face-on, central galaxies at redshift z = 0.02–0.15 and with stellar mass M
⋆ ≈ 1010–2 × 1011
M
⊙. We identify four galaxy groups of similar mass and morphology (mass surface density, velocity dispersion, concentration, and Sérsic index) that can be evolutionarily linked through a life cycle wherein gas content mediates their star formation rate (SFR) and level of AGN activity. Galaxies first consume their gas mostly through bursty star formation, then enter into a transition phase of intermediate gas richness in which star formation and AGNs coexist, before settling into retirement as gas-poor, quiescent systems with residual levels of AGN activity (LINERs). Strongly accreting black holes (Seyferts) live in gas-rich, star-forming hosts, but neither their gas reservoir nor their ability to form stars seems to be impacted instantaneously (timescales ≲0.5 Gyr) by AGN feedback. Our results are inconsistent with AGN feedback models that predict that central, bulge-dominated, Seyfert-like AGNs in massive galaxies have significantly lower molecular gas fractions than inactive galaxies of similar mass, morphology, and SFR.
Lyα Radiative Transfer: Modeling Spectrum and Surface Brightness Profiles of Lyα-emitting Galaxies at Z = 3–6
Authors: Song Hyunmi , Seon Kwang-Il , Hwang Ho Seong 
Published: September 2020

Abstract
We perform Lyα radiative transfer calculations to reproduce the Lyα properties of star-forming galaxies at high redshifts. We model a galaxy as a halo in which the density distributions of Lyα sources and H i plus dust medium are described with exponential functions. We also consider an outflow of the medium that represents a momentum-driven wind in a gravitational potential well. We successfully reproduce both the spectra and the surface brightness profiles of eight star-forming galaxies at z = 3–6 observed with the Multi-Unit Spectroscopic Explorer using this outflowing-halo model with Lyα scattering. The best-fit model parameters (i.e., the outflowing velocity and optical depth) for these galaxies are consistent with those in other studies. We examine the impacts of individual model parameters and input spectrum on the emerging spectrum and surface brightness profile. Further investigations of the correlations among observables (i.e., the spatial extent of Lyα halos and Lyα spectral features) and model parameters, and of spatially resolved spectra are presented as well. We demonstrate that the combination of spectrum and surface brightness profile provides strong constraints on model parameters and thus on the spatial/kinematic distributions of the medium.
Recurring Homologous Solar Eruptions in NOAA AR 11429

Published: September 2020

Abstract
We present the study of three homologous solar eruptions from NOAA active region (AR) 11429 over four days. This large and complex AR is divided into two relatively simple subregions: northeast (NE) and southwest (SW). Recurrent eruptions occurred from the SW subregion over different evolutionary phases, which provided a unique opportunity to isolate the physical processes responsible for solar eruptions. Persistent shearing and convergence of opposite magnetic polarities led to continuous flux cancellation along the SW polarity inversion line (PIL). A filament persistently lying along the SW PIL was observed to survive each eruption, which suggests a partial eruption of the magnetic system. Further, following the first and second eruptions, a sigmoidal magnetic structure of similar morphology was reformed along the SW PIL. The photospheric motion of magnetic flux continuously injected and stored the negative helicity in the partially erupted magnetic system and built up the magnetic free energy for the successive eruptions. These results suggest that the shearing motion and magnetic flux cancellation of opposite fluxes were: (1) the dominant factor, irrespective of the evolutionary phase, that contributed to the recurrent homologous eruption, and (2) the key processes of forming the erupting structure, likely a magnetic flux rope; its long-lasting continuation results in the reformation of an identical erupting structure. The study also finds that similar magnetic topology could result in the magnetic reconnection at the same location, and such flares during the precursor phase would help in the eruption by decreasing the constraint of the overlying magnetic field.
Sequential Lid Removal in a Triple-decker Chain of CME-producing Solar Eruptions
Authors: Joshi Navin Chandra , Sterling Alphonse C. , Moore Ronald L. , Joshi Bhuwan 
Published: September 2020

Abstract
We investigate the onsets of three consecutive coronal mass ejection (CME) eruptions in 12 hr from a large bipolar active region (AR) observed by the Solar Dynamics Observatory (SDO), the Solar Terrestrial Relations Observatory (STEREO), the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI), and the Geostationary Operational Environmental Satellite (GOES). Evidently, the AR initially had a “triple-decker” configuration: three flux ropes in a vertical stack above the polarity inversion line (PIL). Upon being bumped by a confined eruption of the middle flux rope, the top flux rope erupts to make the first CME and its accompanying AR-spanning flare arcade rooted in a far apart pair of flare ribbons. The second CME is made by eruption of the previously arrested middle flux rope, which blows open the flare arcade of the first CME and produces a flare arcade rooted in a pair of flare ribbons closer to the PIL than those of the first CME. The third CME is made by blowout eruption of the bottom flux rope, which blows open the second flare arcade and makes its own flare arcade and pair of flare ribbons. Flux cancellation observed at the PIL likely triggers the initial confined eruption of the middle flux rope. That confined eruption evidently triggers the first CME eruption. The lid-removal mechanism instigated by the first CME eruption plausibly triggers the second CME eruption. Further lid removal by the second CME eruption plausibly triggers the final CME eruption.
Cross-correlation of Far-infrared Background Anisotropies and CMB Lensing from Herschel and Planck Satellites
Authors: Cao Ye , Gong Yan , Feng Chang , Cooray Asantha , Cheng Gong , Chen Xuelei 
Published: September 2020

Abstract
The cosmic infrared background (CIB) anisotropies and cosmic microwave background (CMB) lensing are powerful measurements for exploring cosmological and astrophysical problems. In this work, we measure the autocorrelation power spectrum of the CIB anisotropies in the Herschel–SPIRE HerMES Large Mode Survey (HeLMS) field, and the cross-power spectrum with the CMB lensing measurements from the Planck satellite. The HeLMS field covers more than 270 deg2, which is much larger than in previous analysis. We use the Herschel Level 1 time stream data to merge the CIB maps at 250, 350, and 500 μm bands, and mask the areas where the flux is greater than

or there are no measured data. We obtain the final CIB power spectra at 100 ≤ ℓ ≤ 20,000 by considering several effects, such as beam function, mode coupling, transfer function, and so on. We also calculate the theoretical CIB auto- and cross-power spectra of CIB and CMB lensing by assuming that the CIB emissivity follows a Gaussian distribution in redshift. We find that, for the CIB auto-power spectra, we obtain signal-to-noise ratios (S/Ns) of 15.9, 15.7, and 15.3 at 250, 350, and 500 μm, and for the CIB ⨯ CMB lensing power spectra, S/Ns of 7.5, 7.0, and 6.2 at 250, 350, and 500 μm, respectively. Comparing to previous works, the constraints on the relevant CIB parameters are improved by factors of 2– 5 in this study.
New Light on an Old Problem of the Cores of Solar Resonance Lines

Published: September 2020

Abstract
We reexamine a 50+ yr old problem of deep central reversals predicted for strong solar spectral lines, in contrast to the smaller reversals seen in observations. We examine data and calculations for the resonance lines of H i, Mg ii, and Ca ii, the self-reversed cores of which form in the upper chromosphere. Based on 3D simulations, as well as data for the Mg ii lines from the Interface Region Imaging Spectrograph (IRIS), we argue that the resolution lies not in velocity fields on scales in either of the micro- or macroturbulent limits. Macroturbulence is ruled out using observations of optically thin lines formed in the upper chromosphere, and by showing that it would need to have unreasonably special properties to account for critical observations of the Mg ii resonance lines from the IRIS mission. The power in “turbulence” in the upper chromosphere may therefore be substantially lower than earlier analyses have inferred. Instead, in 3D calculations horizontal radiative transfer produces smoother source functions, smoothing out intensity gradients in wavelength and in space. These effects increase in stronger lines. Our work will have consequences for understanding the onset of the transition region, for understanding the energy in motions available for heating the corona, and for the interpretation of polarization data in terms of the Hanle effect applied to resonance line profiles.
The Effect of Magnetic Twist and Plasma Flow on the Seismology of Oscillating Flux Tubes
Authors: Bahari Karam , Jahan Zeynab 
Published: September 2020

Abstract
In this paper, we study propagating and standing magnetohydrodynamic kink waves in a magnetically twisted and flowing flux tube. The plasma flow is in the direction of the magnetic field; outside the tube, the magnetic field lines are purely longitudinal. The plasma density is constant both inside and outside the tube, and all stationary quantities vary abruptly at the tube boundary. Using the thin tube and weak twist approximations, the dispersion relation, which determines the dependence of the oscillation frequency on the wavenumber and the stationary quantities of the tube, is found. It is shown that the oscillation frequency of the propagating forward (backward) waves increases (decreases) as the flow speed increases; also, the increase in the magnetic twist increases the oscillation frequency of both forward and backward propagating waves. For very weak magnetic twist, the oscillation frequency of both fundamental mode and first overtone standing waves decreases with increasing flow speed. Our results show that if only the plasma flow or magnetic twist is present in the flux tube, the period ratio P
1/P
2 of the fundamental mode to the first overtone of the standing kink waves is equal to 2, but if both the plasma flow and magnetic twist are present in the flux tube, the period ratio can be smaller than 2 and support some observational cases. The asymmetry of the wave about the apex point is not affected much by the magnetic twist, but the magnetic twist causes an overestimation of both the flow speed and kink speed of the coronal loop.
Evidence of Cosmic-Ray Excess from Local Giant Molecular Clouds

Published: September 2020

Abstract
We report the analysis of the Fermi-Large Area Telescope data from six nearby giant molecular clouds (MCs) belonging to the Gould Belt and the Aquila Rift regions. The high statistical γ-ray spectra above 3 GeV well described by power laws make it possible to derive precise estimates of the cosmic-ray (CR) distribution in the MCs. The comparison of γ-ray spectra of Taurus, Orion A, and Orion B clouds with the model expected from Alpha Magnetic Spectrometer (AMS-02) CR measurements confirms these clouds as passive clouds, immersed in an AMS-02-like CR spectrum. A similar comparison of Aquila Rift, Rho Oph, and Cepheus spectra yields significant deviation in both spectral indices and absolute fluxes, which can imply an additional acceleration of CRs throughout the entire clouds. Besides, the theoretical modeling of the excess γ-ray spectrum of these clouds, assuming π
0-decay interaction of CRs in the cloud, gives a considerable amount of an enhanced CR energy density and it shows a significant deviation in spectral shapes compared to the average AMS-02 CR spectrum between 30 GeV and 10 TeV. We suggest that this variation in the CR spectrum of Cepheus could be accounted for by an efficient acceleration in the shocks of winds of OB associations, while in Rho Oph, similar acceleration can be provided by multiple T-Tauri stars populated in the whole cloud. In the case of Aquila Rift, the excess in absolute CR flux could be related to an additional acceleration of CRs by supernova remnants or propagation effects in the cloud.
Impact distributif des transferts privés domestiques et internationaux au Sénégal
Authors: Al-Mouksit Akim , Robilliard Anne-Sophie 
Published: September 2020

L’objectif de cet article est d’évaluer l’impact distributif des transferts privés reçus par les ménages au Sénégal à partir des données de l’Enquête de suivi de la pauvreté au Sénégal de 2011. Cette évaluation repose sur la comparaison de la distribution du revenu disponible par rapport à celle du revenu contrefactuel en l’absence de transferts. Ce revenu contrefactuel est construit selon deux scénarios. Les résultats du premier scénario, qui repose sur l’hypothèse que les transferts privés reçus n’ont pas d’effet sur le comportement du ménage, indiquent que les transferts privés sont égalisateurs en ce que le revenu disponible est plus égalitaire que le revenu contrefactuel hors transferts. L’impact égalisateur des transferts privés apparaît essentiellement tiré par les transferts privés domestiques. En levant l’hypothèse d’exogénéité des transferts, le second scénario suggère que l’effet indirect des transferts privés est potentiellement très important et encore plus égalisateur que l’effet direct. Alors que la littérature met plutôt l’accent sur l’impact distributif des transferts internationaux, les résultats obtenus ici permettent de souligner le rôle important que jouent les transferts privés domestiques dans la réduction des inégalités de revenu.
