Abstract
We report on the design and performance of the Bicep3 instrument and its first three-year data set collected from 2016 to 2018. Bicep3 is a 52 cm aperture refracting telescope designed to observe the polarization of the cosmic microwave background (CMB) on degree angular scales at 95 GHz. It started science observation at the South Pole in 2016 with 2400 antenna-coupled transition-edge sensor bolometers. The receiver first demonstrated new technologies such as large-diameter alumina optics, Zotefoam infrared filters, and flux-activated SQUIDs, allowing ∼10× higher optical throughput compared to the Keck design. Bicep3 achieved instrument noise equivalent temperatures of 9.2, 6.8, and 7.1

and reached Stokes Q and U map depths of 5.9, 4.4, and 4.4 μK arcmin in 2016, 2017, and 2018, respectively. The combined three-year data set achieved a polarization map depth of 2.8 μK arcmin over an effective area of 585 square degrees, which is the deepest CMB polarization map made to date at 95 GHz.
High-resolution VLBI Observations of and Modeling the Radio Emission from the Tidal Disruption Event AT2019dsg
Authors: Mohan Prashanth , An Tao , Zhang Yingkang , Yang Jun , Yang Xiaolong , Wang Ailing 
Published: March 2022

Abstract
A tidal disruption event (TDE) involves the shredding of a star in the proximity of a supermassive black hole (SMBH). The nearby (≈230 Mpc) relatively radio-quiet, thermal-emission-dominated source AT2019dsg is the first TDE with a potential neutrino association. The origin of nonthermal emission remains inconclusive; possibilities include a relativistic jet or a subrelativistic outflow. Distinguishing between them can address neutrino production mechanisms. High-resolution very long baseline interferometry 5 GHz observations provide a proper motion of 0.94 ± 0.65 mas yr−1 (3.2 ± 2.2 c; 1σ). Modeling the radio emission favors an origin from the interaction between a decelerating outflow (velocity ≈0.1 c) and a dense circumnuclear medium. The transition of the synchrotron self-absorption frequency through the observation band marks a peak flux density of 1.19 ± 0.18 mJy at 152.8 ± 16.2 days. An equipartition analysis indicates an emission-region distance of ≥ 4.7 × 1016 cm, magnetic field strength ≥ 0.17 G, and number density ≥ 5.7 × 103 cm−3. The disruption involves a ≈2 M
⊙ star with a penetration factor ≈1 and a total energy output of ≤ 1.5 × 1052 erg. The outflow is radiatively driven by the accretion of stellar debris onto the SMBH. Neutrino production is likely related to the acceleration of protons to peta-electron-volt energies and the availability of a suitable cross section at the outflow base. The present study thus helps exclude jet-related origins for nonthermal emission and neutrino production, and constrains nonjetted scenarios.
Global Structure and Dominant Particle Acceleration Mechanism of the Heliosheath: Definitive Conclusions
Authors: Fisk L. A. , Gloeckler G. 
Published: March 2022

Abstract
During its exploration of the heliosheath, the region that lies between the termination shock of the solar wind and the heliopause that separates the solar wind from the local interstellar medium, the Voyager 1 spacecraft (V1) in 2012 encountered an apparent boundary where there was a precipitous decrease in energetic particles accelerated in the heliosheath, the so-called anomalous cosmic rays (ACRs), and from the occasional plasma density measurements on V1, a density comparable to the expected density in the interstellar medium. In 2013, the Voyager principal investigators announced that this apparent boundary was the heliopause and that V1 had entered the interstellar medium. In 2014, Fisk & Gloeckler presented a detailed model that demonstrated that the apparent boundary was simply an internal surface within the heliosheath, across which compressed solar wind flows and will continue to flow until it encounters the actual heliopause. There is compelling observational evidence that the model of Fisk & Gloeckler for the nose region of the heliosheath is correct: V1 did not cross the heliopause in 2012 and is not now in the interstellar medium. There is also compelling observational evidence that the ACRs are accelerated in the heliosheath by the pump acceleration mechanism of Fisk & Gloeckler. The success of the models of Fisk & Gloeckler confirms that the plasma in the nose region of the heliosheath consists of two separate components, the pickup ions and ACRs, and the thermal solar wind, and as a unique plasma is worthy of more study and, if possible, more exploration.

Abstract
Both NASA’s Solar Dynamics Observatory (SDO) and the JAXA/NASA Hinode mission include spectropolarimetric instruments designed to measure the photospheric magnetic field. SDO’s Helioseismic and Magnetic Imager (HMI) emphasizes full-disk, high-cadence, and good-spatial-resolution data acquisition while Hinode’s Solar Optical Telescope Spectro-Polarimeter (SOT-SP) focuses on high spatial resolution and spectral sampling at the cost of a limited field of view and slower temporal cadence. This work introduces a deep-learning system, named the Synthetic Inversion Approximation (SynthIA), that can enhance both missions by capturing the best of each instrument’s characteristics. We use SynthIA to produce a new magnetogram data product, the Synthetic Hinode Pipeline (SynodeP), that mimics magnetograms from the higher-spectral-resolution Hinode/SOT-SP pipeline, but is derived from full-disk, high-cadence, and lower-spectral-resolution SDO/HMI Stokes observations. Results on held-out data show that SynodeP has good agreement with the Hinode/SOT-SP pipeline inversions, including magnetic fill fraction, which is not provided by the current SDO/HMI pipeline. SynodeP further shows a reduction in the magnitude of the 24 hr oscillations present in the SDO/HMI data. To demonstrate SynthIA’s generality, we show the use of SDO/Atmospheric Imaging Assembly data and subsets of the HMI data as inputs, which enables trade-offs between fidelity to the Hinode/SOT-SP inversions, number of observations used, and temporal artifacts. We discuss possible generalizations of SynthIA and its implications for space-weather modeling. This work is part of the NASA Heliophysics DRIVE Science Center at the University of Michigan under grant NASA 80NSSC20K0600E, and will be open-sourced.
Diversity of Mulgedio-Aconitetea communities in the Sudetes Mts. (SW Poland) in the Central European context
Authors: Świerkosz Krzysztof , Reczyńska Kamila 
Published: March 2022

Aims: To describe the compositional and ecological diversity of Mulgedio-Aconitetea communities in the Sudetes Mts. and their foothills. Study area: The Sudetes Mts. (Southwestern Poland). Methods: A total of 399 vegetation relevés from own field studies and the literature were sorted into groups that match the higher syntaxa of the EuroVegChecklist and associations described in the literature. Diagnostic species of the so delimited associations were determined with the phi-coefficient of association, and maps of the associations produced. Direct ordination methods were applied to identify the main environmental gradients shaping the plant communities. Results: We distinguished nine associations, belonging to four alliances: submontane and colline communities (Petasition officinalis: Geranio phaei-Urticetum dioicae, Petasitetum hybridi, Chaerophyllo hirsuti-Petasitetum albi, Prenanthetum purpureae), upper montane nitrophilous communities (Rumicion alpini: Rumicetum alpini); subalpine communities with a dominance of graminoids and ferns (Calamagrostion villosae: Poo chaixii-Deschampsietum cespitosae, Crepido conyzifoliae-Calamagrostietum villosae, Athyrietum filicis-feminae) and subalpine tall-herb communities (Adenostylion alliariae: Cicerbitetum alpinae). Altitude, light availability, and bedrock type, which determines nutrient availability and soil reaction, played an important role in differentiating the studied communities. Conclusions: For convenience, we placed the four alliances in four separate orders as in the EuroVegChecklist. The fact that our ordination diagram separated only two main groups suggests the need of further research in this matter.

A Novel Approach to Fostering Academic-Practice Partnerships: The DNP Project Executive Summary
Authors: Diegel-Vaceka Lauren , Yonkaitis Catherine F. 
Published: March 2022

Background:
Practice partnerships are vital to academic nursing for opportunities for robust student clinical experiences. The Doctor of Nursing Practice (DNP) scholarly project provides benefits for both students and practice partners; however, traditional academic dissemination methods such as student posters and publications are not internal communication formats used by practice partners.

Method:
An assignment was developed for DNP students to write an executive summary of the completed scholarly project for their practice-partner organization stakeholders.

Results:
Students used business writing skills to develop a one-page document summarizing the implementation and results of their project for a document applicable to the business of health care.

Conclusion:

Incorporating an executive summary of the DNP scholarly project emphasizes the value of student-led initiatives to organizations and can strengthen academic-practice partnerships. This innovative approach to dissemination of outcomes delivers a practical business communications document that is valuable to practice mentors and organizational leaders.

ABSTRAKTradisi kawin tangkap biasanya dilakukan oleh keluarga kaya karena terkait dengan mahar yang harus dibayarkan pada pihak perempuan mahal. Namun tradisi kawin tangkap yang terjadi sekarang sudah melenceng dan tidak sesuai lagi dengan tradisi. Tujuan penelitian ini adalah untuk melakukan kajian terkait Tardisi Kawin Tangkap Sumba dan bagaimana Prespektif Undang-Undang R I Nomor 1 Tahun 1974 tentang Perkawinan. Penelitian ini bersifat deskriptif dengan menggunakan data sekunder yaitu jurnal-jurnal dan surat-surat kabar online yang kredibel. Setelah data dikumpulkan kemudian peneliti menyusun hasil penelitian secara sistematis. Hasil penelitian pustaka yang dilakukan peneliti menemukan bahwa Kawin tangkap yang berlaku saat ini seakan menjadi praktek penculikan yang berlindung di bawah nilai adat Sumba dan tidak sesuai dengan praktek kawin tangkap pada zaman dulu. Tradisi kawin tangkap secara paksa telah melanggar UU hukum pidana Pasal 328 dan tidak sesuai dengan asas keluarga dan syarat perkawinan yang terdapat pada UU RI No 1 Tahun 1974 tentang Perkawinan. Disarakan seluruh pihak terkait baik dari tokoh masyarakat, tokoh agama maupun Pemerintah Daerah Sumba untuk melakukan sosialisai pentingnya menjaga tertib Hukum agar kasus kejadian kawin tangkap secara paksa tidak terjadi pada perempuan Sumba.Kata Kunci: Kawin tangkap, UU RI No 1 Tahun 1974

Authors: Martínez Muñoz Enrique , Licona Olmos Jazmín , Rivera Gómez Pedro 
Published: March 2022

La finalidad del presente trabajo fue analizar la percepción de los clientes respecto al servicio que otorga una pyme que ofrece diversos servicios, para ello se consideraron 4 dimensiones y 9 variables, en la dimensión empresa las variables (instalaciones, equipamiento y materiales), la dimensión personal las variables (capacitación, disposición y atención otorgada), la dimensión Servicios con las variables (cumplimiento, capacidad de respuesta, flexibilidad, expectativas) y la dimensión Satisfacción en General con la variable (cumplir expectativas), las cuales puedan incidir en la percepción del servicio otorgado a los clientes y como consecuencia en la preferencia comercial de la pyme.
El presente estudio de caso se realizó en trabajadores de una empresa de multiservicios, cuya característica principal es no tener una actividad principal, sino se dedican a proveer todos aquellos servicios que sus empresas clientes les demanden, sin especializarse en una sola de ellas. Por esta razón, una empresa multiservicios puede ofrecer servicios de limpieza, seguridad, mantenimiento, hostelería, trasporte, entre otras, todo al mismo o a diferentes clientes, Todolí A. (2015). Dicha empresa se encuentra ubicada en la región centro del estado de Hidalgo, donde se obtuvo información del servicio otorgado por la empresa en cuestión por medio electrónico, a los diversos clientes de la misma, la investigación de llevo a cabo en la primera mitad del año 2020.

La metodología de la investigación, se utilizó un enfoque mixto, debido a que permitió una mejor comprensión del fenómeno a estudiar. Por una parte, se enlazaron elementos cualitativos, producto de la observación y de la percepción que tienen los empleados acerca del servicio proporcionado, posterior al análisis de las entrevistas realizadas, se permitió identificar las variables que fueron utilizadas para elaborar el cuestionario y aplicarlo en la segunda etapa cuantitativa, los resultados obtenidos mediante la aplicación de encuestas, en las que se determinaron las características de las relaciones entre las variables; una vez obtenidos estos datos numéricos, se cuantificaron y sometieron a un análisis estadístico.

El nivel de la investigación es descriptiva y exploratoria porque permite relacionar factores para conocer el servicio al cliente otorgado por la empresa de multiservicios con las variables que infieren en la satisfacción de sus clientes. En los resultados obtenidos se observa que las dimensiones que cuentan con mayor impacto son las de Personal, Servicio y Satisfacción en general en la percepción del servicio al cliente otorgado.
Dada la naturaleza del presente caso de estudio, sus resultados solo aplicarán de manera específica a la empresa investigada y a sus particulares circunstancias, procesos, personal y contexto, por lo que no se podrán establecer patrones que se puedan aplicar de manera generalizada

Hydrolyzed Polyacrylamide Screening for EOR in an Indonesia Mature Oil Field
Authors: Erfando Tomi , Siregar Gerry 
Published: March 2022

Most of Indonesia’s oil field has been producing the oil for long period of time. For this reason, enhanced oil recovery (EOR) method becomes the most promising method to improve oil production for the country. Chemical flooding, especially polymer flooding is the simplest and the most commonly applied chemical enhanced oil recovery technique, since it can be used after water flooding process. Screening is considered the first step in evaluating and selecting potential polymers for reservoirs. Therefore, this research aims to select partially Hydrolyzed Polyacrylamide (HPAM) base polymers to find suitable polymer for a targeted mature reservoir in Indonesia. A polymer screening study was carried out on 3 HPAM polymers to identify a potential candidate which can withstand reservoir conditions. These are Kerui, Zekindo, and FP 3630S. Initially, a comprehensive rheological (viscosity, shear rate) study was conducted at various polymer concentrations (500 - 2500 ppm) and brine to investigate the polymers. Then, filtration and screen factor test was conducted at various concentrations (1000 - 2000 ppm). Then, a thermal stability test was conducted at anaerobic condition and 140 °F for 2 months. Finally, for oil recovery used core flooding test. Based on the result of the test, FP 3630S with a concentration of 2000 ppm was chosen for the core flooding test. The test was designed in 3 steps: At first, water injected into the sample, followed by polymer-solvent at 2000 ppm concentrated of 1 PV, the finally injected by water. The results of core flooding showed oil recovery of 28.93 % OOIP. Finally, this study was performed to develop screening criteria and to correlate oil recovery prediction.
HIGHLIGHTS · One of the efforts to increase old field production is by choosing the right type of polymer to be injected · Polymer screening was carried out through testing stages, namely rheology, filtration and screen factor, thermal stability, and core flooding · Selected one type of polymer that meets all the qualifications of the screening testsGRAPHICAL ABSTRACT
