Abstract
The Green Bank North Celestial Cap survey is a 350 MHz all-sky survey for pulsars and fast radio transients using the Robert C. Byrd Green Bank Telescope. To date, the survey has discovered over 190 pulsars, including 33 millisecond pulsars and 24 rotating radio transients. Several exotic pulsars have been discovered in the survey, including PSR J1759+5036, a binary pulsar with a 176 ms spin period in an orbit with a period of 2.04 days, an eccentricity of 0.3, and a projected semi-major axis of 6.8 light seconds. Using seven years of timing data, we are able to measure one post–Keplerian parameter, advance of periastron, which has allowed us to constrain the total system mass to 2.62 ± 0.03 M
⊙. This constraint, along with the spin period and orbital parameters, suggests that this is a double neutron star system, although we cannot entirely rule out a pulsar-white dwarf binary. This pulsar is only detectable in roughly 45% of observations, most likely due to scintillation. However, additional observations are required to determine whether there may be other contributing effects.

Abstract
The CHIME/FRB Project has recently released its first catalog of fast radio bursts (FRBs), containing 492 unique sources. We present results from angular cross-correlations of CHIME/FRB sources with galaxy catalogs. We find a statistically significant (p-value ∼ 10−4, accounting for look-elsewhere factors) cross-correlation between CHIME FRBs and galaxies in the redshift range 0.3 ≲ z ≲ 0.5, in three photometric galaxy surveys: WISE × SCOS, DESI-BGS, and DESI-LRG. The level of cross-correlation is consistent with an order-one fraction of the CHIME FRBs being in the same dark matter halos as survey galaxies in this redshift range. We find statistical evidence for a population of FRBs with large host dispersion measure (∼400 pc cm−3) and show that this can plausibly arise from gas in large halos (M ∼ 1014
M
⊙), for FRBs near the halo center (r ≲ 100 kpc). These results will improve in future CHIME/FRB catalogs, with more FRBs and better angular resolution.
Constraints on the Occurrence of ‘Oumuamua-Like Objects
Authors: Levine W. Garrett , Cabot Samuel H. C. , Seligman Darryl , Laughlin Gregory 
Published: November 2021

Abstract
At present, there exists no consensus in the astronomical community regarding either the bulk composition or the formation mechanism for the interstellar object 1I/2017 U1 (‘Oumuamua). With the goal of assessing the merits of the various scenarios that have been suggested to explain ‘Oumuamua's appearance and observed properties, we report a number of new analyses and provide an up-to-date review of the current hypotheses. We consider the interpretations that can reconcile ‘Oumuamua's observed non-Keplerian trajectory with the nondetection of traditional cometary volatiles. We examine the ability of these proposed formation pathways to populate the galaxy with sufficient interstellar objects such that the detection of ‘Oumuamua by Pan-STARRS would be statistically favored. We consider two exotic ices, hydrogen and nitrogen, showing that the frigid temperature requirement for the former and the necessary formation efficiency of the latter pose serious difficulties for these interpretations. Via order-of-magnitude arguments and hydrodynamical cratering simulations, we show that impacts on extrasolar Kuiper Belt analogues are not expected to generate N2 ice fragments as large as ‘Oumuamua. In addition, we discuss observational tests to confirm the presence of these ices in future interstellar objects. Next, we examine the explanations that attribute ‘Oumuamua's properties to other compositions: ultraporous dust aggregates and thin membranes powered by solar radiation pressure, among others. While none of these hypotheses are perfectly satisfactory, we make predictions that will be testable by the Vera Rubin Observatory to resolve the tension introduced by ‘Oumuamua.
Universal Protoplanetary Disk Size under Complete Nonideal Magnetohydrodynamics: The Interplay between Ion-neutral Friction, Hall Effect, and Ohmic Dissipation
Authors: Lee 李 Yueh-Ning 悅寧 , Marchand Pierre , Liu 劉 Yu-Hsuan 宇軒 , Hennebelle Patrick 
Published: November 2021

Abstract
The role of nonideal magnetohydrodynamics has been proven critical during the formation of protoplanetary disks, particularly in regulating their sizes. We provide a simple model to predict the disk size under the interplay among ambipolar diffusion, the Hall effect, and ohmic dissipation. The model predicts a small disk size of around 20 au that depends only sublinearly on disk parameters, for a wide range of initial conditions of subsolar mass and moderate magnetization. It is able to explain phenomena manifested in existing numerical simulations, including the bimodal disk behavior under parallel and antiparallel alignment between the rotation and magnetic field. In the parallel configuration, the disk size decreases and eventually disappears. In the antiparallel configuration, the disk has an outer partition (or pseudodisk), which is flat, shrinking, and short-lived, as well as an inner partition, which grows slowly with mass and is long-lived. Even with significant initial magnetization, the vertical field in the disk can only dominate at the early stage when the mass is low, and the toroidal field eventually dominates in all disks.

Abstract
We present near-infrared spectroscopy of Nova Herculis 2021 (V1674 Her), obtained over the first 70 days of its evolution. This fastest nova on record displays a rich emission line spectrum, including strong coronal line emission with complex structures. The hydrogen line fluxes, combined with a distance of

⊙. The coronal lines appeared at day 11.5, the earliest onset yet observed for any classical nova, before there was an obvious source of ionizing radiation. We argue that the gas cannot be photoionized, at least in the earliest phase, and must be shocked. Its temperature is estimated to be 105.57±0.05 K on day 11.5. Tentative analysis indicates a solar abundance of aluminum and an underabundance of calcium, relative to silicon, with respect to solar values in the ejecta. Further, we show that the vexing problem of whether collisional ionization or photoionization is responsible for coronal emission in classical novae can be resolved by correlating the temporal sequence in which the X-ray supersoft phase and the near-infrared coronal line emission appear.
The Critical Need for Advanced Training in Electronic Records Use: Implications for Clinical Practice, Education, and the Advancement of Athletic Training
Authors: Lam Kenneth C. , Anderson Barton E. , Welch Bacon Cailee E. 
Published: November 2021

Context
The effective use of electronic records (ie, electronic health records or electronic medical records) is essential to professional initiatives and the overall advancement of the athletic training profession. However, evidence suggests that comprehensive patient care documentation and widespread use of electronic records are still limited in athletic training. The lack of formal training and education for clinicians and students is often cited as a primary barrier to electronic record use. Other health care disciplines have used academic electronic health record (AEHR) systems to address these barriers with promising results.

Objectives
To identify common challenges associated with the effective use of electronic records in clinical practice, discuss how an AEHR system can address these challenges and encourage more effective use of electronic records, and describe strategies for deploying AEHRs in the athletic training profession.

Description
The AEHR is an electronic records system specifically designed for educational use to support simulation learning among all types of learners (eg, practicing clinicians, students). Mimicking the form and function of an electronic health record, the AEHR offers various educational tasks, including patient care documentation projects, critical reviews of standardized patient cases, and assessments of patient care data for quality improvement efforts.

Clinical and Research Advantages
Recent evidence suggests that the use of an AEHR can improve knowledge and enhance skills. Specifically, AEHR use has been associated with enhanced attitudes toward electronic health record technology, increased informatics competencies, and improved documentation skills. Also, the use of an AEHR has been associated with improved critical thinking and decision-making skills. This tool appears to be valuable for health professions education, and athletic training stands to benefit from its use to better train and upskill clinicians and students alike for clinical practice. Although the implementation of an AEHR will require much time and large-scale coordinated efforts, it will be a worthy investment to address current challenges and advance the athletic training profession.

AbstractThis paper is an analysis of the BNN.XIV.E.46 manuscript by Francisco de Quevedo, which contains his “silvas”, among other pieces, with the purpose of applying to them the information that the manuscript provides. We will expose the similarities among the pieces and explain the order in which the “silvas” appear, as well as the presence in the manuscript of a text in Arabic. We conclude that the “silvas,” a corpus selected, corrected and put in order by Quevedo himself, deserves to be edited the way he decided.

The purpose of the work was to identify the most effective agrobiological measures of plantation cultivation of wood energy crops – various types of willow on drained organogenic soils of Forest-steppe and Polesie, to develop technologies for their cultivation and to carry out energy, economic and environmental assessments of their cultivation on land extracted from intensive cultivation. Research methods – field with a complex of biometric, agrochemical and laboratory studies, mathematical and statistical.The results of studies conducted on medium-deep drained old-time carbonate peatland are presented. Data on agroecological assessment of soil and climatic conditions of agricultural lands were obtained to create energy plantations in the area of excess moisture, agrochemical and water-physical properties and features of the water-air regime of organogenic soils were investigated. As a result of the analysis, the data found that they fully meet the requirements of growing high-performance energy crops.It has been established that the most effective way of basic soil processing is to plant willows in ploughed furrows with an area of food of 0,9 x0,7 m and harvest every two to three years. The most productive on average in five years was willow three-song – 27,1-28,0 t per hectare and willow rod – 23,2 and 31,7 t per hectare of dry mass in Forest Steppe and Polissya, 28,2 and 21,2 t per hectare, respectively. According to economic indicators, the highest conditional net profit (21,1 thousand UAH per hectare) and the level of profitability (305%) provided willow rod on the scheme of planting 0,9 x 0,7 m and cleaning in the form of chips every three years.

The purpose of the article was, on the basis of monitoring studies, to establish the peculiarities of the state of natural waters in the agrolandscapes of the Forest-steppe zone under various agrotechnogenic loads. The study used the method of agroecological monitoring and laboratory (methods of chemical, physico-chemical analysis using modern methods of atomic absorption spectrophotometry, flame photometry in accordance with the requirements of the quality management system, DSTU 3973-2000). The study of the state of natural water in 2015–2020 was conducted by the staff of the Department of Agroecology and analytical research of the NSC “Institute of Agriculture of NAAS” in the agro-landscapes of the Right Bank Forest-Steppe in Kyiv region: in Kyiv-Sviatoshynskyi district - v. Gatne, v. Kruglik,v. Kryukivshchyna, v. Vita Poshtova, in Vasylkiv district -v. Dzvinkove, in the Tarashchansky district - the v. Rizhky, in the Left-Bank Forest-Steppe - in the Poltava region, Shishatsky district, v. Manachynivka. The results of water analysis at stationary points of the Right-Bank and Left-Bank Forest-Steppe indicate that none of them was distinguished by the stability of physicochemical and chemical indicators, the quality of drinking water in rural settlements directly depends on the ecological state of agricultural landscapes and individual farms. The state of drinking water in the system of decentralized water supply of rural settlements in most cases did not correspond to the standards in force in Ukraine, which indicates a high anthropogenic load on agricultural landscapes, an insufficient level of ecological culture and the need for monitoring. The issue of monitoring natural waters and reducing the risks of their pollution is important from the point of view of improving the quality of drinking water in rural areas.

Peatland ecosystems in Bosnia and Herzegovina represent a relict remain of the vegetation, flora and fauna from the glaciation periods. Peatlands are widespread on the North, where they occupy large areas of northern Europe, Asia and Canada. Occurrence of this type of ecosystems in Bosnia and Herzegovina contains an indication of nature conservation in general and represents an extraordinary natural value. The status of peatland ecosystems in the Balkans should be carefully monitored especially today, at the time of the already recognizable effects of climate change. The preserved structure and functionality of these ecosystems might indicate satisfactory degree of resilience to climate change, but adverse state warns on the need to take appropriate actions. Multiply drivers as overexploitation of natural resources, water, air and soil pollution and spread of invasive alien species, also have a negative effect on peatland ecosystems. In order to assess the conditions of peatland ecosystems in Bosnia and Herzegovina, researches were carried out on Vranica and Zvijezda mountain in central Bosnia. Researches was conducted including the following communities: Sphagno-Piceetum montanum Stef 1964, Sphagnetum recurvo-subsecundi Grgić et al. 1991, Menyanthi-Sphagnetum Grgić et al. 1991 Scirpetum silvatici Ht et H-ić, Calthaetum rostratae Lakušić et al. 1991, Abieti-Piceetum illyricum Fuk. 1960 Stef. 62 s.l ect. To investigate existing conditions state of the peatland ecosystems, floristic elements and life forms were determined for every plant species. A comparison of previous and today’s state of these communities was conducted, associated with analysis of Ellenberg’s indices for temperature, light, soil reaction etc. According to Lakušić et al., 1991., these type of ecosystems in Bosnia and Herzegovina was satisfactory. However, today's finding shows severe changes. The loss of peatland habitats was recorded in the entire area of research. The main identified drivers are deforestation, habitat conversion and drainage of watercourses. In order to protect this type of ecosystems and important indicator species it is necessary to implement different conservation and restoration activities.

Published: November 2021

Background: Stevia is a natural, healthy, unconventional replacement to the table sugar and artificial sweetener. Phytochemicals present in it exerts an influence on the microbial flora of the mouth. Hence, study was planned to compare the effects of stevia with different sugars on the plaque pH.
Methodology: The present study was carried in department of Public Health Dentistry between 9am-12pm. It was a triple blinded Crossover Randomized Controlled Clinical Trial with LSD design. All the 40 subjects were exposed to all four interventions sequentially, at weekly intervals with 1 week wash out period. (Intervention: A- Table sugar, B- Jaggery, C- Stevia, D- Milk tea without sugar). Inferential statistics was done using Repeated measures of ANOVA followed by Post hoc pairwise comparison and Three-way RMANOVA to determine relationship between SUGAR * WEEK * TIME interaction. Level of significance was set at p value at 0.05.
Results: Plaque pH assessments were performed at 4 points of time intervals (at baseline, 1 min, 20min, 60 min). Overall significance differences were seen in plaque pH at different time intervals for all interventions. Intergroup comparison showed potential efficacy of stevia in maintaining plaque pH.
Conclusion: In the present study, it was found that stevia has the least cariogenic potential when compared with jaggery and refined sugar. Jaggery also did not show a significant reduction in plaque pH. Therefore, Stevia and Jaggery can be compared for their anti-cariogenic properties. This study has been registered under the Clinical Trial Registry of India CTRI/2020/12/03003
