Abstract
Introduction Evidence supports long-term oral antibiotic prophylaxis to prevent cholangitis after Kasai procedure. Data regarding perioperative intravenous prophylaxis are lacking. Ascending pathogens from the intestine are made responsible for recurrent cholangitis. Therefore, we analyzed the flora in the upper jejunum during the Kasai procedure and their potential impact on postoperative cholangitis.
Materials and Methods In 26 patients, swabs were taken at the bowel prepared for the Roux-en-Y-loop. Our postoperative protocol includes intravenous third-generation cephalosporins for 2 weeks and rectal steroids starting at day 4. Cholangitis was defined as the postoperative reappearance of acholic stools or increase of serum bilirubin in combination with fevers or increase of inflammatory parameters. In this scenario, Tazocin was administered for another 2 weeks.
Results Swabs remained sterile in nine patients (34.6%). In 17 patients (65.4%), gram-positive and gram-negative pathogens were identified; all belonging to physiological intestinal flora. A total of 96.2% pathogens were covered by the antibiotic prophylaxis. The cholangitis incidence was 55.6% in the sterile cohort, and 23.5% in the gram-positive and gram-negative cohort (p = 0.06). In the cholangitis cohort, no significant differences were detected for the age at Kasai and the pre- and postoperative total bilirubin.
Conclusion We found that our antibiotic regiment covered bacteria in the upper gastrointestinal (GI) tract in the majority of our patients at the time of Kasai. Nonetheless, a significant proportion of patients developed signs of cholangitis. There was no higher rate of cholangitis in patients with resistant bacteria. Thus, our data do not support the hypothesis of extended postoperative intravenous antibiotics to prevent ascending cholangitis.

Published: August 2020

AbstractObjectives We surveyed people with epilepsy (PWE) and uncontrolled seizures on the challenges which they have had in their lives with respect to educational achievement, employment, and marriage. We tried to scrutinize their reasons and perceptions for their social underachievement and difficulties.Materials and Methods Adult patients above 25 years of age, with epileptic seizures for more than 5 years, who were investigated at Shiraz Comprehensive Epilepsy Center, from January until March 2019, were studied. We prepared a questionnaire for our study and asked whether they have any college education? If they have ever married? And, if they are employed?Results Seventy patients enrolled in our study. Age of the patients was 33 ± 6 years (range: 26–59 years) and their age at onset of epilepsy was 14 ± 9 years (range: 0–35 years). Forty-four patients (63%) never received any college education; 30 patients (43%) were single; and finally, 37 patients (53%) were unemployed. The most common reasons perceived by the patients for these life challenges were functional disability (e.g., inability to study or to work), social discrimination and stigmatization, and uncontrolled seizures and the associated consequences (i.e., fear of having seizures).Conclusion Many PWE (both men and women) and uncontrolled seizures suffer from social underachievement and challenges in their daily lives. Various strategies may help PWE to overcome these challenges.
Approaching text genre

Abstract
In the present study, we sought to clarify how differences in contextualized experience influence the performance of
participants engaged in genre decision-making. Using a simple learning algorithm, we ran a series of computational simulations to model the
effects that context and cue competition have on the way readers of different backgrounds make genre decisions. Next, we used the results of
those simulations as predictions for our behavioural genre decision experiment. Differences in test performance were strongly influenced by
the factors that have long been known to influence learning: Cue competition and its embedding in a specific context jointly modulate what
gets learned and that inevitably affects later performance. We discuss our findings in the context of learning and literary genres.
Science fiction prototyping’s features and impact on college students’ perceptions of writing
Authors: Nicholes Justin 
Published: August 2020

AbstractThe present study develops an applied literariness study by exploring both the features, and the impact, of science fiction prototyping (SFP) on college students’ perceptions of disciplinary, or field-specific, writing. College students (N = 83), who were English (n = 35) or STEM (science, technology, engineering, mathematics) majors (n = 48), composed micro-science fiction prototyping (µSFP), a genre that blends creative and science writing. Linguistic Inquiry and Word Count (LIWC2015) analysis demonstrated that, aside from a more positive average emotional tone,µSFP written fell psycho-linguistically between personal and science writing. English and STEM majors’µSFP stories were similar in terms of analytical levels, clout, authenticity, emotional tone, and use of words. Mann-Whitney U tests indicated that, while English majors evaluated creative writing as significantly more relevant to their future career goals pre-intervention than did STEM majors (p = .04,r = .23), this difference vanished post-intervention. Additionally, while STEM majors evaluated science writing as significantly more worth their time to study (p = .042,r = .22) and relevant to their major (p = .01,r = .28) pre-intervention than did English majors, these differences disappeared post-intervention. Wilcoxon signed-ranks tests indicated that, while English majors’ ownership and evaluation of science and creative writing did not change, STEM majors’ evaluations of creative writing as relevant to their majors and future careers were significantly higher post-intervention (p = .015,r = .35)

Published: August 2020

Background In the United States, alcohol use disorder (AUD) is common and costly but substantially undertreated. Rurality is an important determinant of health that may influence receipt of evidence-based alcohol-related care. In a large, national sample of Veterans Health Administration (VA) patients with AUD with documented and non-Hispanic Black, Hispanic, or non-Hispanic White race/ethnicity, we examine whether meeting national Healthcare Effectiveness Data and Information Set (HEDIS) quality measures for specialty addictions care and receiving evidence-based medications for AUD differs across patients living in urban, large rural, and small rural areas. Methods VA electronic health record data were used to identify all patients with AUD documented in Fiscal Year 2012. Rurality was measured using a three-category rural and urban commuting area (RUCA) classification linked to patient zip code. Logistic regression models with clustered standard errors—iteratively adjusted for hypothesized confounders—were used to estimate the likelihood and marginal probabilities of receiving care for patients living in small and large rural areas, relative to urban areas. Primary outcomes included HEDIS initiation (any visit within 14 days of initial AUD visit after a 60-day period of no treatment), HEDIS engagement (2 or more AUD visits within 30 days of HEDIS initiation visit) and having any filled prescription for AUD medications (naltrexone, disulfiram, acamprosate, or topiramate). Results For all outcomes, patients living in large and small rural areas had a lower likelihood of receiving evidence-based AUD treatment than patients living in urban areas (all p-values < 0.05); differences in marginal probabilities across groups were relatively small. Conclusions In this national sample of VA patients with AUD, those living in more rural areas were less likely to receive evidence-based treatment for AUD than those living in urban areas. Further research is needed to investigate strategies to increase receipt of specialty care and pharmacotherapy in more rural areas.

High-precision location for occluded reference hole based on robust extraction algorithm
Authors: Lou Huacheng , Lu Min , Cui Haihua , Jiang Tao , Tian Wei , Huang Yi 
Published: August 2020

Abstract
The reference hole is significant for pre-positioning in high-precision robot drilling. The visual and optical measurement of such holes is of great benefit in terms of improving location accuracy during robot drilling and subsequent rivet-in-hole assembly. However, the detection and location of the reference hole via visual sensors still presents signifcant challenges, owing to the occlusion of perforator clips prior to practical drilling. This study proposes a robust extraction algorithm, based on gray clustering and edge detection, for locating the occluded reference holes (ORH). Firstly, the boundary box of the ORH is segmented using a template matching and density clustering algorithm. Secondly, the discrete arcs of the ORH are extracted via a combination of K-means clustering, pixel-intensity, and concave points extraction based on edge concavity. Finally, the target arcs are filtered and obtained based on their ellipse geometric properties, followed by the center extraction of the ellipse fitting. The experimental results show that the location accuracy achieved in this way is within 0.03 mm, which is sufficiently accurate for robot drilling. Moreover, the ORH data can be extracted and located successfully even in challenging industrial environments, with varying levels of illumination.

Published: August 2020

Abstract
Patterned sapphire substrate has been used extensively in the growth of gallium nitride (GaN) material and related light emitting devices (LEDs). Recently, carbon nanotube patterned sapphire (CNTPS) was utilized to improve the GaN material and LED devices. In this article, intrinsic analyzation of LEDs on CNTPS were studied. LEDs grown on three layers of CNTs showed highest radiative quantum efficiency and internal quantum efficiency, while LEDs on double layers of CNTs exhibited the best light output power and external quantum efficiency. The physics of carriers’ injection, radiative, non-radiative, Auger recombination and light extraction in CNT patterned LEDs were unraveled by the ‘ABC’ modelsimulation.

Authors: Wang Hong-Feng , Yuan Mao , Yin Qian , Guo Ping , Zhu Wei-Wei , Li Di , Feng Si-Bo 
Published: August 2020

Abstract
Radio frequency interference (RFI) is an important challenge in radio astronomy. RFI comes from various sources and increasingly impacts astronomical observation as telescopes become more sensitive. In this study, we propose a fast and effective method for removing RFI in pulsar data. We use pseudo-inverse learning to train a single hidden layer auto-encoder (AE). We demonstrate that the AE can quickly learn the RFI signatures and then remove them from fast-sampled spectra, leaving real pulsar signals. This method has the advantage over traditional threshold-based filter method in that it does not completely remove contaminated channels, which could also contain useful astronomical information.
Study of the Modified Gaussian Model on olivine diagnostic spectral features and its applications in space weathering experiments
Authors: Han Hui-Jie , Lu Xiao-Ping , Yang Ya-Zhou , Zhang Hao , Mutelo Admire Muchimamui 
Published: August 2020

Abstract
The absorption features of olivine in visible and near-infrared (VNIR) reflectance spectra are the key spectral parameters in its mineralogical studies. Generally, these spectral parameters can be obtained by exploiting the Modified Gaussian Model (MGM) with a proper continuum removal. However, different continua may change the deconvolution results of these parameters. This paper investigates the diagnostic spectral features of olivine with diverse chemical compositions. Four different continuum removal methods with MGM for getting the deconvolution results are presented and the regression equations for predicting the Mg-number (Fo#) are introduced. The results show that different continua superimposed on the mineral absorption features will make the absorption center shift, as well as the obvious alterations in shape, width and strength of the absorption band. Additionally, it is also found that the logarithm of a second-order polynomial continuum can match the overall shape of the spectrum in logarithmic space, and the improved regression equations applied to estimate the chemical composition of olivine-dominated spectra also have a better performance. As an application example, the improved approach is applied to pulse laser irradiated olivine grains to simulate and study the space weathering effects on olivine diagnostic spectral features. The experiments confirm that space weathering can make the absorption band center shift toward longer wavelength. Therefore, the Fo# estimated from remote sensing spectra may be less than its actual chemical composition. These results may provide valuable information for revealing the difference between the spectra of olivine grains and olivine-dominated asteroids.

Authors: George Maria Selvam A , Dhineshbabu R , Gumus Ozlem AK 
Published: August 2020

Abstract
This present work investigates the dynamical behaviors of a new form of fractional order three dimensional system with a chaotic attractor of the one-scroll structure and its discretized counterpart. Firstly, existence and parametric conditions for local stability analysis of steady states of the model are addressed. Then the bifurcation theory is applied to investigate the presence of Neimark - Sacker (NS) bifurcations at the coexistence steady state taking the time delay as a bifurcation parameter in the discrete fractional order system. Also the trajectories, phase diagrams, limit cycles, bifurcation diagrams, attractors for period - 1, 2, 3, 4, 5 and a chaotic attractor with one scroll are exhibited for biologically meaningful sets of parameter values in the discretized system. Finally, several numerical examples are presented to assure the validity of the theoretical results and further rich dynamics of the model is explored as well.

Natural convection in an inclined parallelogrammic enclosure: Effect non-uniform heating
Authors: Ravindra P , Pandurangappa C , Sankar M 
Published: August 2020

Abstract
In this paper, numerical simulations are presented to understand the influence of inclination angle of a tilted parallelogrammic enclosure. The upper and lower boundaries of the enclosure are treated as thermally insulated; right wall is uniform cooled while the left wall is non-uniformly heated with either sinusoidal or linear thermal profiles. Using Darcy law, the momentum equations are modeled and unsteady energy equation is considered. The model equations are numerically solved using finite difference method, in particular, using ADI and SLOR methods. Based on standard coordinate transformations, the governing equations are transformed to rectangular shaped enclosure computational domain. In this analysis, due to large number parameters, the inclination angle of the enclosure is fixed. The flow and thermal processes are depicted through streamlines and isotherms, while the thermal transport rates are illustrated through Nusselt number profiles. Numerical simulations capture the effects of side wall inclination angle and non-uniform thermal conditions on the flow and thermal patterns, heat transport rates for various parametric ranges of the problem.
Value distribution theory of Nevanlinna
Authors: Rajeshwari S 
Published: August 2020

Abstract
In the field of research, a century old value distribution theory of Nevanlinna is still alive. It contains a broad range of implementations inside and outside a function theory. It is the study to speculate different values by complex function. As you are aware that each single non-constant variable polynomial upon ℂ has has not more than one root which is complex. This builds polynomials with real coefficients, because upon seeing the real number as a complex number with its imaginary part equal to zero up to constant multiple. This article express mainly the classical version for complex analytic map to the Riemann sphere of single variable, with priority on mero-morphic functions in the z-plane.
On feasibility of azimuthal flow studies with Principal Component Analysis
Authors: Altsybeev Igor 
Published: August 2020

Abstract
It is shown that the Principal Component Analysis applied to azimuthal single-particle distributions allows to perform flow analysis in ways that are analogous to the traditional approaches based on multi-particle correlations. In particular, symmetric cumulants are considered. It is demonstrated also that statistical fluctuations due to a finite number of particles per event practically do not play a role for higher order PCA-based cumulants.
Heavy flavor dynamics across system size at the LHC
Authors: Katz Roland , Prado Caio A. G. , Noronha-Hostler Jacquelyn , Suaide Alexandre A. P. 
Published: August 2020

Abstract
One of the fundamental signatures of the Quark Gluon Plasma has been the suppression of heavy flavor (specifically D mesons), which has been measured via the nuclear modification factor, RAA
and azimuthal anisotropies, vn
, in large systems. However, multiple competing models can reproduce the same data for RAA
to vn
. In this talk we break down the competing effects that conspire together to successfully reproduce RAA
and vn
in experimental data using Trento+v-USPhydro+DAB-MOD. Then using our best fit model we make predictions for RAA
and vn
across system size for 208PbPb, 129XeXe, 40ArAr, and 16OO collisions. We find that 0–10% centrality has a non-trivial interplay between the system size and eccentricities such that system size effects are masked in v2 whereas in 30–50% centrality the eccentricities are approximately constant across system size and, therefore, is a better centrality class to study D meson dynamics across system size.
PHENIX results on

Authors: Lebedev Alexandre 
Published: August 2020

Abstract
One of the big questions in quarkonia production is how heavy-quark pairs are produced in the initial hard scattering and hadronize into final quarkonia states. This question also affects the estimation of quarkonia breakup cross-sections and color screening in heavy ion collisions. Many existing models describe well general features of quarkonia production like cross-section and transverse momentum distributions. In order to differentiate between various models one has to study quarkonia production in more details. One of such tools is a study of angular distributions of decay leptons, usually called polarization. The PHENIX experiment has measured inclusive
