Authors: Amorim L. L. , Kepler S. O. , Külebi Baybars , Jordan S. , Romero A. D. 
Published: February 2023

Abstract
White dwarfs are excellent research laboratories as they reach temperatures, pressures, and magnetic fields that are unattainable on Earth. To better understand how these three physical parameters interact with each other and with other stellar features, we determined the magnetic field strength for a total of 804 hydrogen-rich white dwarfs (WDs) of which 287 are not in the literature. We fitted the spectra observed with the Sloan Digital Sky Survey using atmospheric models that consider the Zeeman effect due to the magnetic field at each point in the stellar disk. Comparing magnetic and nonmagnetic WDs, the literature already shows that the magnetic ones have on average higher mass than the nonmagnetic. In addition to that, magnetic fields are more common in cooler WDs than in hotter WDs. In consonance, we found that those with higher magnetic field strengths tend to have higher masses, and lower temperatures, for which models indicate the crystallization process has already started. This reinforces the hypothesis that the field is being generated and/or amplified in the cooling process of the white dwarf. Our sample constitutes the largest number of white dwarfs with determined magnetic fields to date.
Jets and Rings in Images of Spinning Black Holes
Authors: Papoutsis Evan , Bauböck Michi , Chang Dominic , Gammie Charles F. 
Published: February 2023

Abstract
We develop a “dual-cone” model for millimeter wavelength emission near a spinning black hole. The model consists of optically thin, luminous cones of emission, centered on the spin axis, which are meant to represent jet walls. The resulting image is dominated by a thin ring. We first consider the effect of the black hole’s spin on the image and show that the dominant effect is to displace the ring perpendicular to the projection of the spin axis on the sky by

. This effect is lower order in a
* than changes in the shape and size of the photon ring itself but is undetectable without a positional reference. We then show that the centerline of the jet can provide a suitable reference: its location is exactly independent of spin if the observer is outside the cone and nearly independent of spin if the observer is inside the cone. If astrophysical uncertainties can be controlled, then spin displacement is large enough to be detectable by future space very long baseline interferometry missions. Finally, we consider ring substructure in the dual-cone model and show that features in total intensity are not universal and depend on the cone-opening angle.
Relativistic Correction to the r-mode Frequency in Light of Multimessenger Constraints
Authors: Ghosh Suprovo , Pathak Dhruv , Chatterjee Debarati 
Published: February 2023

Abstract
The r-mode oscillations of rotating neutron stars are promising candidates for continuous gravitational-wave (GW) observations. The r-mode frequencies for slowly rotating Newtonian stars are well known and independent of the equation of state (EOS), but for neutron stars several mechanisms can alter the r-mode frequency for which the relativistic correction is dominant and relevant for most of the neutron stars. The most sensitive searches for continuous GWs are those for known pulsars for which GW frequencies are in targeted narrow frequency bands of a few hertz. In this study, we investigate the effect of several state-of-the-art multimessenger constraints on the r-mode frequency for relativistic, slowly rotating, barotropic stars. Imposing these recent constraints on the EOS, we find that the r-mode frequency range is slightly higher than that from the previous study and the narrowband frequency range can increase by up to 25% for the most promising candidate PSR J0537−6910 depending on the range of compactness. We also derive universal relations between r-mode frequency and dimensionless tidal deformability that can be used to estimate the dynamical tide of the r-mode resonant excitation during the inspiral signal. These results can be used to construct the parameter space for r-mode searches in GW data and also constrain the nuclear EOS following a successful r-mode detection.
Antarctic Penguin Biogeography Project: Database of abundance and distribution for the Adélie, chinstrap, gentoo, emperor, macaroni, and king penguin south of 60 S
Authors: Che-Castaldo Christian , Humphries Grant , Lynch Heather , Humphries Grant 
Published: February 2023

The Antarctic Penguin Biogeography Project is an effort to collate all known information about the distribution and abundance of Antarctic penguins through time and to make such data available to the scientific and management community. The core data product involves a series of structured tables with information on known breeding sites and surveys conducted at those sites from the earliest days of Antarctic exploration through to the present. This database, which is continuously updated as new information becomes available, provides a unified and comprehensive repository of information on Antarctic penguin biogeography that contributes to a growing suite of applications of value to the Antarctic community. One such application is the Mapping Application for Antarctic Penguins and Projected Dynamics (MAPPPD; www.penguinmap.com), a browser-based search and visualization tool designed primarily for policymakers and other non-specialists, and mapppdr, an R package developed to assist the Antarctic science community. This dataset contains records of Pygoscelis adeliae, Pygoscelis antarctica, Pygoscelis papua, Eudyptes chrysolophus, Aptenodytes patagonicus, and Aptenodytes forsteri annual nest, adult, and/or chick counts conducted during field expeditions or collected using remote sensing imagery, that were subsequently gathered by the Antarctic Penguin Biogeography Project from published and unpublished sources, at all known Antarctic penguin breeding colonies south of 60 S from 1892-11-01 to 2022-02-12.
This dataset collates together all publicly available breeding colony abundance data (1979-2022) for Antarctic penguins in a single database with standardized notation and format. Colony locations have been adjusted as necessary using satellite imagery, and each colony has been assigned a unique four-digit alphanumeric code to avoid confusion. These data include information previously published in a variety of print and online formats as well as additional survey data not previous published. Previously unpublished data derive primarily from recent surveys collected under the auspices of the Antarctic Site Inventory, Penguin Watch, or by the Lynch Lab at Stony Brook University.
Global Health Competencies and Educational Needs for Nursing Students in South Korea
Authors: Lee Sujin , Kim Eunjoo , Yoon Ju Young 
Published: February 2023

Background:
Despite the increasing demand for global health education, relatively few global health courses currently are offered in Korea.

Method:
This mixed-methods study examined the need for global health competency and global health education experience for nursing students. A survey of 208 nursing students was conducted from May 2020 to August 2020, and three focus groups were conducted with 12 nursing students.

Results:
The average score of global health nursing competencies was 2.8 ± 0.7 on a scale ranging from 1 to 4. Female, higher academic achievement, fluent English, and higher global health education experience had a significant effect on global health competency. The most influential factor was more experience with global health education. Nursing students' perceptions and educational needs related to global health education were classified into four subthemes.

Conclusion:

The development of global health education programs for nursing students is needed.

Bilensectomy: Safety and Visual Outcomes in Angle-Supported, Iris-Fixated, and Posterior Chamber Phakic Intraocular Lenses
Authors: Vargas Veronica , Alió Jorge L. , Alió del Barrio Jorge L. , Cantó-Cerdán Mario , Barraquer Rafael I. , Duch Francisco , Marinho Antonio 
Published: February 2023

Purpose:
To report the visual and refractive outcomes, intraoperative and postoperative complications, and main causes of bilensectomy in the different types of phakic intraocular lenses (pIOLs).

Methods:
This was a retrospective multicenter study that included 234 eyes of 185 patients that underwent bilensectomy. Patients were divided into three groups depending on the pIOL that was explanted (angle-supported, iris-fixated, or posterior chamber). The main reasons leading to the indication for bilensectomy, time elapsed between pIOL implantation and bilensectomy, intraoperative and postoperative complications, uncorrected and corrected distance visual acuity (UDVA and CDVA), and endothelial cell density loss 1 year after bilensectomy were evaluated.

Results:
There was a statistically significant improvement in UDVA and CDVA after bilensectomy in all groups. Cataract development was the main reason for bilensectomy, followed by significant endothelial cell density loss. Time between pIOL implantation and bilensectomy was significantly greater in eyes with an anterior chamber pIOL.

Conclusions:
Bilensectomy outcomes in general are good. Iris-fixated lenses, particularly hyperopic, are more prone to intraoperative complications and endothelial cell loss than the other pIOLs models. The results show that bilensectomy is a safe and effective procedure with a relatively low rate of intraoperative and postoperative complications and acceptable refractive predictability.

Clinical Retinal Image Quality of a Non-diffractive Wavefront-Shaping Extended Depth of Focus (Vivity) Intraocular Lens
Authors: Al-Amri Saad Abdulrahman J. , Alió Jorge L. , Milán-Castillo Roberto , D'Oria Francesco , Martinez-Abad Antonio , Yebana Pilar , Subirana Nuria , Al-Harbi Ziyad , Plaza-Puche Ana B. , Alió del Barrio Jorge L. 
Published: February 2023

Purpose:
To evaluate clinical retinal optical image quality following implantation of an extended depth of focus intraocular lens (EDOF IOL) (Vivity; Alcon Laboratories, Inc), and to compare it with a monofocal and a trifocal IOL.

Methods:
This prospective, comparative, case-control study included 88 eyes implanted with: (1) 19 monofocal IOLs (AcrySof SA60AT; Alcon Laboratories, Inc); (2) 38 EDOF IOLs (AcrySof IQ Vivity); and (3) 31 trifocal IOLs (AT LISA tri 839MP; Carl Zeiss Meditec AG). Total root mean square, ocular lower (LOA) and higher (HOA) order aberrations, point spread function (PSF) Strehl ratio (PSF with LOA), and PSF Strehl ratio excluding LOA (PSF without LOA) were analyzed using a Pyramidal WaveFront-based sensor aberrometer Osiris (Costruzione Strumenti Oftalmici) at two different pupil sizes (3 and 4 mm).

Results:

The trifocal IOL showed the highest PSF without LOA at both pupil sizes (0.52 ± 0.12 and 0.31 ± 0.07, respectively), followed by the AcrySof SA60AT (0.39 ± 0.10 and 0.27 ± 0.07) and AcrySof IQ Vivity (0.34 ± 0.11 and 0.24 ± 0.09) (
P
< .001). The AcrySof IQ Vivity and monofocal IOLs were comparable (
P
> .05). Despite the comparable postoperative low spherical equivalent among the IOL groups, the AT LISA tri 839MP retinal image quality (PSF with LOA) was the most severely affected by such residual refractive errors (dropped to 0.26 ± 0.06 at 3 mm;
P
< .001) compared to the monofocal AcrySof SA60AT (0.24 ± 0.07 at 3 mm) and EDOF Acrysof IQ Vivity (0.23 ± 0.06 at 3 mm) groups. The PSF with LOA was comparable (
P
> .05) among the three groups at both the 3-and 4-mm pupil size.

Conclusions:
Although trifocal IOLs provided significantly better retinal image quality if influence of LOA is excluded, they also demonstrated to be the most sensitive to residual refractive errors. Both the EDOF Acrysof IQ Vivity and mono-focal AcrySof SA60AT IOLs showed a comparable retinal image quality, and they are also comparable with trifocal IOLs when considering the clinically real PSF (PSF with LOA).

Authors: Siddiqui Safanah , Lutz Gabriel , Tabatabai Ali , Nathan Rachel , Anders Megan , Gibbons Miranda , Russo Marguerite , Whitehead Sarah , Rock Peter , Scalea Thomas , Kheirbek Raya E. 
Published: February 2023

Background
Extracorporeal membrane oxygenation (ECMO) combined with COVID-19 presents challenges (eg, isolation, anticipatory grief) for patients and families.

Objective
To (1) describe characteristics and outcomes of patients with COVID-19 receiving ECMO, (2) develop a practice improvement strategy to implement early, semistructured palliative care communication in ECMO acknowledgment meetings with patients’ families, and (3) examine family members’ experiences as recorded in clinicians’ notes during these meetings.

Methods
Descriptive observation of guided, in-depth meetings with families of patients with COVID-19 receiving ECMO, as gathered from the electronic medical record of a large urban academic medical center. Most meetings were held within 3 days of initiation of ECMO.

Results
Forty-three patients received ECMO between March and October 2020. The mean patient age was 44 years; 63% of patients were Hispanic/Latino, 19% were Black, and 7% were White. Documentation of the ECMO acknowledgment meeting was completed for 60% of patients. Fifty-six percent of patients survived to hospital discharge. Family discussions revealed 7 common themes: hope, reliance on faith, multiple family members with COVID-19, helping children adjust to a new normal, visitation restrictions, gratitude for clinicians and care, and end-of-life discussions.

Conclusion
Early and ongoing provision of palliative care is feasible and useful for highlighting a range of experiences related to COVID-19. Palliative care is also useful for educating patients and families on the benefits and limitations of ECMO therapy.
IL-1/MyD88–Dependent G-CSF and IL-6 Secretion Mediates Postburn Anemia

Published: February 2023

Abstract
The anemia of critical illness (ACI) is a nearly universal pathophysiological consequence of burn injury and a primary reason burn patients require massive quantities of transfused blood. Inflammatory processes are expected to drive postburn ACI and prevent meaningful erythropoietic stimulation through iron or erythropoietin supplementation, but to this day no specific inflammatory pathways have been identified as a critical mechanism. In this study, we examined whether secretion of G-CSF and IL-6 mediates distinct features of postburn ACI and interrogated inflammatory mechanisms that could be responsible for their secretion. Our analysis of mouse and human skin samples identified the burn wound as a primary source of G-CSF and IL-6 secretion. We show that G-CSF and IL-6 are secreted independently through an IL-1/MyD88–dependent mechanism, and we ruled out TLR2 and TLR4 as critical receptors. Our results indicate that IL-1/MyD88–dependent G-CSF secretion plays a key role in impairing medullary erythropoiesis and IL-6 secretion plays a key role in limiting the access of erythroid cells to iron. Importantly, we found that IL-1α/β neutralizing Abs broadly attenuated features of postburn ACI that could be attributed to G-CSF or IL-6 secretion and rescued deficits of circulating RBC counts, hemoglobin, and hematocrit caused by burn injury. We conclude that wound-based IL-1/MyD88 signaling mediates postburn ACI through induction of G-CSF and IL-6 secretion.
Cowongan in Javanese Islamic mysticism: A study of Islamic philosophy in Penginyongan society
Authors: Supriyanto Supriyanto 
Published: February 2023

This study aims to reveal the interaction of local Javanese culture with an Islamic philosophical approach originating from the Cowongan tradition performed by shamans accompanied by dances with holy ladies and reciting mantras. This tradition is a prayer asking the gods to send down rain. This article emphasised that the Cowongan tradition places mystical power as the dominant element in life, which is embodied in symbols. The study of mysticism is closer to the study of Sufism which presents it as Islamic mysticism with the color of syncretism of religious teachings with local cultural practices embodied by mystical-occult practices as the Penginyongan culture.Contribution: This research contributed to the fact that traditions that are good and acceptable to society can become the law as part of the Urf, which need to be maintained as long as they do not conflict with Sharia.
Is Africa Godforsaken? Neo-Pentecostal prophetism on African human agency and transcendence
Authors: Banda Collium 
Published: February 2023

African neo-Pentecostal prophets (NPPs) use their prophetic rituals like deliverance services and anointed objects such as anointed oil, to bring God’s presence to people to empower their human agency (power to act) and transcendence (power to overcome). This use of prophetic systems prompts the question: What does the NPPs’ teaching that Africans need prophetic rituals and anointed objects for God to empower their agency and transcendence communicate about God’s presence in Africa? A further question that emerges is: How can Christian doctrines like God’s transcendence (divine beyondness) and immanence (divine nearness) address the African reliance on NPPs’ prophetic systems for God’s power to exercise their human agency and transcendence to confront their context of poverty? Consequently, this article uses the doctrine of God’s transcendence and immanence to evaluate the implications of NPPs’ prophetic systems to empower Africans to act and overcome their undesirable situations in Africa. The article challenges NPPs to realise that the transcendent God is fully immanent in poor Africa and that poverty in Africa is not caused by the lack of God’s presence but evil socioeconomic and political structures that hinder the poor from exercising their human agency and transcendence. The contribution of the article is challenging African NPPs to be informed by a sound doctrine of God in their attempts to empower poor Africans to deal with their poverty.Intradisciplinary and/or interdisciplinary implications: The article uses insights from the doctrine of God and African traditional religious (ATR) view of God to critique the use of NPPs’ rituals and anointed objects to empower African human agency and transcendence.

Authors: Al-Obaidi Iman , Saleem Hamsa , Hammodat Alaa 
Published: February 2023

In this article, we investigate the stability of flowing fluid in a horizontal cavity. The walls of which consists of a porous material under the influence of a magnetic field (MF) perpendicular to the cavity plane. We find that the real part of the wave velocity is negative for any value of the Hartmann number and the Ghratshof number is greater than zero. In addition, we convert the governing equations to non-dimensional formulas. So, we obtain that Reynolds number, wave number (k), Hartmann number , Ghratshof number, and Darcy number affect on the stability of the model through the graphs of these numbers.
Factors Influencing Brain Drain Among Health Workers in Ghana
Authors: Adjei-Mensah Sussana 
Published: February 2023

Purpose: The advent of the covid-19 pandemic exacerbated the need for more professional health workers to serve as front-line workers in hospitals in Ghana and other developing countries. This study aimed to ascertain the factors influencing health workers' brain drain in Ghana.
Methodology: The study was a survey with an accessible population of 15510 people in different categories of health workers. Sampling was through stratification for a sample size of 400 respondents across the Greater Accra Region of Ghana. Structured questionnaires were used for the data collection and analyzed using the Statistical Package for Social Sciences (SPSS) as a statistical tool to generate descriptive statistics that included the mean, standard deviation and ranks based on which inferences were drawn.
Findings: The study found that government inaction on the conditions of service of health workers such as low remuneration, inadequate opportunities for staff development, poor equipment replacement policies, political interferences in their workplaces, high standards of living and inadequate housing and personal reasons amount to the reasons why Ghana is losing the majority of her finest health workers to the developed nations. The study concluded that the migration of healthcare professionals from developing to developed nations has negative effects on the delivery of healthcare in Ghana especially coming out of a deadly pandemic.
Recommendation: The study recommends that government deals with the motivation and hygiene factors as well as the push and pull economic factors that drive many health workers to seek "greener pastures" outside the country hence the trend could continue in the coming years.
