Published: July 2021

Abstract
The impact of reduced pressure annealing on ferroelectric properties in hafnium-zirconium oxide (HZO) films deposited by sputtering has been investigated. It is demonstrated that the HZO films annealed at 600 °C at less than 100 Pa show excellent ferroelectric properties, whereas the HZO films annealed at more than 1000 Pa show degraded electrical properties. This is presumably due to the introduction of oxygen vacancies, which stabilize the ferroelectric orthorhombic phase. Thermal stability can be also improved for the HZO films annealed at reduced pressures. In addition, ferroelectric gate transistor operation is demonstrated using an HZO gate insulator annealed at 100 Pa with the indium-tin-oxide channel.

Published: July 2021

Background: Non-Functional Requirements (NFR) have a direct impact on the architecture of the system, thus it is essential to identify NFRs in the initial phases of software development.
Aim: The work is based on extraction of relevant keywords from NFR descriptions by employing text mining steps and thereafter classifying these descriptions into one of the nine types of NFRs.
Method: For each NFR type, keywords are extracted from a set of pre-categorized specifications using Information-Gain measure. Then models using 8 Machine Learning (ML) techniques are developed for classification of NFR descriptions. A set of 15 projects (containing 326 NFR descriptions) developed by MS students at DePaul University are used to evaluate the models.
Results: The study analyzes the performance of ML models in terms of classification and misclassification rate to determine the best model for predicting each type NFR descriptions. The Naïve Bayes model has performed best in predicting “maintainability” and “availability” type of NFRs.
Conclusion: The NFR descriptions should be analyzed and mapped into their corresponding NFR types during the initial phases. The authors conducted cost benefit analysis to appreciate the advantage of using the proposed models.

The goal of the CAMELS project is to provide theory predictions for different observables as a function of cosmology and astrophysics, and it is the largest suite of cosmological (magneto)hydrodynamic simulations designed to train machine-learning algorithms.

. We describe the simulations in detail and characterize the large range of conditions represented in terms of the matter power spectrum, cosmic star formation rate density, galaxy stellar mass function, halo baryon fractions, and several galaxy scaling relations. We show that the IllustrisTNG and SIMBA suites produce roughly similar distributions of galaxy properties over the full parameter space but significantly different halo baryon fractions and baryonic effects on the matter power spectrum. This emphasizes the need for marginalizing over baryonic effects to extract the maximum amount of information from cosmological surveys. We illustrate the unique potential of CAMELS using several machine-learning applications, including nonlinear interpolation, parameter estimation, symbolic regression, data generation with Generative Adversarial Networks, dimensionality reduction, and anomaly detection.
Electromagnetic Signatures from the Tidal Tail of a Black Hole—Neutron Star Merger
Authors: Darbha Siva , Kasen Daniel , Foucart Francois , Price Daniel J. 
Published: July 2021

Abstract
Black hole—neutron star (BH–NS) mergers are a major target for ground-based gravitational wave observatories. A merger can also produce an electromagnetic counterpart (a kilonova) if it ejects neutron-rich matter that assembles into heavy elements through r-process nucleosynthesis. We study the kilonova signatures of the unbound dynamical ejecta of a BH–NS merger. We take as our initial state the results from a numerical relativity simulation and then use a general relativistic hydrodynamics code to study the evolution of the ejecta with parameterized r-process heating models. The unbound dynamical ejecta is initially a flattened, directed tidal tail largely confined to a plane. Heating from the r-process inflates the ejecta into a more spherical shape and smooths its small-scale structure, though the ejecta retains its bulk directed motion. We calculate the electromagnetic signatures using a 3D radiative transfer code and a parameterized opacity model for lanthanide-rich matter. The light curve varies with viewing angle because of two effects: asphericity results in brighter emission for orientations with larger projected areas, while Doppler boosting results in brighter emission for viewing angles more aligned with the direction of bulk motion. For typical r-process heating rates, the peak bolometric luminosity varies by a factor of ∼3 with orientation while the peak in the optical bands varies by ∼3 magnitudes. The spectrum is blueshifted at viewing angles along the bulk motion, which increases the V-band peak magnitude to ∼−14 despite the lanthanide-rich composition.
Switchback Boundary Dissipation and Relative Age

Published: July 2021

Abstract
We examine Parker Solar Probe (PSP) magnetic field and plasma observations during its first encounter with the Sun in early 2018 November. During this perihelion time, impulsive reversals in the magnetic field, called “switchbacks,” were found in the data set characterized by a quick rotation in B along with a simultaneous increase in solar wind flow. In this work, we examine the structure and morphology of 920 switchback boundaries as PSP enters and exits the structures, specifically looking for evidence of boundary degradation, dissipation, and associated ultralow frequency (ULF) magnetic wave activity. We find that boundaries with the most abrupt, step-function-like change in B
r and V
r also show little evidence of dissipation and ULF wave activity. In contrast, there is a set of boundaries that appears highly degraded with ULF magnetic activity in the vicinity of the boundary. We thus infer that the steep, step-like boundaries with little ULF activity are relatively young in comparison to the degraded boundaries. The distribution in relative ages suggests that the switchback boundary formation process is dynamic and evolving, even occurring near the PSP observation point inside of 40 R

Resolving the Emission Regions of the Crab Pulsar’s Giant Pulses

Published: July 2021

Abstract
The Crab pulsar has striking radio emission properties, with the two dominant pulse components—the main pulse and the interpulse—consisting entirely of giant pulses. The emission is scattered in both the Crab Nebula and the interstellar medium, causing multipath propagation and thus scintillation. We study the scintillation of the Crab’s giant pulses using phased Westerbork Synthesis Radio Telescope data at 1668 MHz. We find that giant pulse spectra correlate at only ∼2%, much lower than the one-third correlation expected from a randomized signal imparted with the same impulse response function. In addition, we find that the main pulse and the interpulse appear to scintillate differently; the 2D cross-correlation of scintillation between the interpulse and main pulse has a lower amplitude and is wider in time and frequency delay than the 2D autocorrelation of the main pulses. These lines of evidence suggest that the giant pulse emission regions are extended, and that the main pulse and interpulse arise in physically distinct regions that are resolved by the scattering screen. Assuming the scattering takes place in the nebular filaments, the emission regions are of order a light-cylinder radius, as projected on the sky. With further very long baseline interferometry and multifrequency data, it may be possible to measure the distance to the scattering screens, the size of giant pulse emission regions, and the physical separation between the pulse components.

Published: July 2021

BACKGROUND: The prevalence of TB in Kendal Regency from 2007 to 2011 has inclined to increment. In 2007, TB prevalence was 55 per 100,000 population, and it became 121 per 100,000 population in 2011.
AIM: The present study aims at obtaining Kendal district government policy to decrease the number of TB cases in the Kendal Regency.
METHODS: The method of situation analysis involved secondary and primary data analysis, field survey, confirmation, cost calculation, and matriculation of various factors of multivariate analysis.
RESULTS: There are some Problems of TB found from the Situation Analysis in Kendal Regency is related to the Topography of Kendal Regency, which is located both in the highlands and coastal areas because as an indicator of high-risk areas for TB transmission and the development of TB germs, poverty and high population at Kendal Regency result in the job scarcity, the educational background within the productive age in 2014 was low. Also, most of the people are tobacco farmers, which was included in a predisposing factor associated with some TB caused by prolonged nicotine exposure.
CONCLUSION: Recommendations as TB Advocacy Actions relevant to the Health Office and Regional Working Unit’s action plan that can be carried out immediately is a workshop on the preparation of health service standards as promotive, preventive, curative, and rehabilitative health services; the development of equal energy or human resources standards the addition of P2M personnel, especially TB, online recording and reporting systems need to be initiated for facilitating access; counseling TB through mass media to be accessible to the community; and cross-sectoral collaboration between Community Health Center.
