Mentir para vacunarse
Authors: Vargas Pedro Ernesto 
Published: October 2021

No hace mucho tiempo, un grupo pequeño pero significativo de ciudadanos nacionales cruzaron las fronteras, surcaron los aires, se mecieron con las olas para vacunarse contra COVID-19 porque en el horizonte nacional, no había señales de protegerse con ellas, por no pertenecer a alguno de los grupos prioritarios. La escasez del recurso financiero y de las vacunas obligó considerar la necesidad de proteger primero con la vacuna a los grupos vulnerables, conocidos en ese momento, como las personas mayores de 70 años y el personal de salud, de las instituciones hospitalarias. Aún con vacunas suficientes, el más frágil no debe hacer filas y esperar porque otros gozan de los privilegios de la familiaridad, la amistad o la posición social. Además, en otras latitudes, las vacunas se empezaban a botar al final del día.
Neutrino-dominated Accretion Flows: A Second Nucleosynthesis Factory in Core-collapse Supernovae and Regulating the Iron Markets in Galaxies

Published: October 2021

Abstract
Cosmic metals are widely believed to be produced by supernovae (SNe) and compact-object mergers. Here, we discuss the nucleosynthesis of neutrino-dominated accretion flows (NDAFs) with outflows in the centers of core-collapse SNe (CCSNe), and show that the outflows from NDAFs can have a significant contribution to the 56Ni abundances of faint explosions if the masses of the progenitor stars are within about 25–50 M
⊙. Less-massive progenitor stars can produce more 56Ni than their more-massive counterparts in the NDAF outflow nucleosynthesis channel. Therefore, we find that the total (i.e., CCSNe and NDAF outflows) 56Ni mass per CCSN depends only weakly upon the mass of the progenitor star. In terms of metallicity evolution, the ratio of 56Fe (produced by the decay of 56Ni) mass to the initial total gas mass can increase by ∼1.95 times if the upper limits of the nucleosynthesis yields from NDAF outflows and CCSNe are considered. Our results might have significant implications for the chemical evolution of the solar neighborhood, galaxies, and active galactic nuclei.
Second-scale Submillimeter Variability of Sagittarius A* during Flaring Activity of 2019: On the Origin of Bright Near-infrared Flares
Authors: Murchikova Lena , Witzel Gunther 
Published: October 2021

Abstract
In 2019, Sgr A*—the supermassive black hole in the Galactic Center—underwent unprecedented flaring activity in the near-infrared (NIR), brightening by up to a factor of 100 compared to quiescent values. Here we report Atacama Large Millimeter/submillimeter Array (ALMA) observations of Sgr A*'s continuum variability at 1.3 mm (230 GHz)—a tracer of the accretion rate–conducted one month after the brightest detected NIR flare and in the middle of the flaring activity of 2019. We develop an innovative light-curve extraction technique which (together with ALMA’s excellent sensitivity) allows us to obtain light curves that are simultaneously of high time resolution (2 s) and high signal-to-noise ratio (∼500). We construct an accurate intrinsic structure function of the Sgr A* submm variability, improving on previous studies by about two orders of magnitude in timescale and one order of magnitude in sensitivity. We compare the 2019 June variability behavior with that of 2001–2017 and suggest that the most likely cause of the bright NIR flares is magnetic reconnection.
Observational Kinematic Characteristics of Blobs in Solar Coronal Helmet and Pseudo Streamers

Published: October 2021

Abstract
We examine two helmet and two pseudo streamers (HSs and PSs) observed on 2018 and 2019. The HSs (PSs) have dark coronal cavities and stretched loop structures (twin coronal cavities and narrow plasma sheet) at their bases, which are well observed in K-Coronagraph (K-Cor). Their outer-corona structures (top of core, cusp, and stalk) are also clearly identified in LASCO-C2. By investigating LASCO-C2 images, we find the following characteristics. (1) Blobs persistently move outward along the centers of HSs and PSs as well as their legs until the base of a stalk. We also detect outward-moving blobs along their outsides. (2) Blobs along the HS centers formed below tops of cores (∼2.6 R
⊙), while the other HS and PS blobs might be generated below 2.0 R
⊙. (3) HS blob speeds are generally similar to or smaller than the solar wind speed based on Parker’s model, while PS ones are larger. (4) HS (PS) blob speeds along the streamer centers are slightly smaller (larger) than those along the streamer legs, might be explained by the expansion-factor model. The blob speeds inside streamer structures (centers and legs) are larger than outside ones closer to solar equator, similar to typical solar wind speed distributions at solar minimum. (5) Several blobs along the HS centers only show sudden speed jumps at streamer cusps. These might be caused by sunward tension forces of overlying stretched closed fields and/or bidirectional outflows by magnetic reconnections in the cusps.
Are Delayed Radio Flares Common in Tidal Disruption Events? The Case of the TDE iPTF 16fnl
Authors: Horesh Assaf , Sfaradi Itai , Fender Rob , Green David A. , Williams David R. A. , Bright Joe S. 
Published: October 2021

Abstract
Radio emission from tidal disruption events (TDEs) originates from an interaction of an outflow with the super-massive black hole (SMBH) circumnuclear material (CNM). In turn, this radio emission can be used to probe properties of both the outflow launched at the event and the CNM. Until recently, radio emission was detected only for a relatively small number of events. While the observed radio emission pointed to either relativistic or sub-relativistic outflows of different nature, it also indicated that the outflow has been launched shortly after stellar disruption. Recently, however, delayed radio flares, several months and years after stellar disruption, were reported in the case of the TDE ASASSN-15oi. These delayed flares suggest a delay in the launching of outflows and thus may provide new insights into SMBH accretion physics. Here, we present a new radio data set of another TDE, iPTF 16fnl, and discuss the possibility that a delayed radio flare also has been observed in this case, ∼5 months after optical discovery, suggesting that this phenomenon may be common in TDEs. Unlike ASASSN-15oi, the data for iPTF 16fnl is sparse and the delayed radio flare can be explained by several alternative models: among them are a complex varying CNM density structure and a delayed outflow ejection.
Signatures of a Distant Planet on the Inclination Distribution of the Detached Kuiper Belt
Authors: Anderson Kalee E. , Kaib Nathan A. 
Published: October 2021

Abstract
A distant, massive planet in the outer solar system has recently been proposed to explain some observed features of extreme trans-Neptunian objects (TNOs). Here we use N-body simulations of the formation of the Kuiper Belt and Oort cloud as well as a survey simulator to compare models of the solar system with and without a ninth planet to one another as well as to observations. The main mechanism for TNOs to be deposited into the distant (a > 50 au), detached (q > 40 au) region of the Kuiper Belt in the eight-planet model is Kozai–Lidov oscillation of objects in mean motion resonances (MMR) with Neptune. This effect does not deposit low-inclination (i ≲ 20°) objects into this region. However, we find that the ninth planet generates a group of distant, detached TNOs at low inclinations that are not present in the eight-planet model. This disparity between the eight-planet and nine-planet models could provide a strong constraint on a possible planet nine with further detections of TNOs in the distant, detached region of the Kuiper Belt.
Void Replenishment: How Voids Accrete Matter Over Cosmic History
Authors: Vallés-Pérez David , Quilis Vicent , Planelles Susana 
Published: October 2021

Abstract
Cosmic voids are underdense regions filling up most of the volume in the universe. They are expected to emerge in regions comprising negative initial density fluctuations, and subsequently expand as the matter around them collapses and forms walls, filaments, and clusters. We report results from the analysis of a cosmological simulation specially designed to accurately describe low-density regions, such as cosmic voids. Contrary to the common expectation, we find that voids also experience significant mass inflows over cosmic history. On average, 10% of the mass of voids in the sample at z ∼ 0 is accreted from overdense regions, reaching values beyond 35% for a significant fraction of voids. More than half of the mass entering the voids lingers on periods of time ∼10 Gyr well inside them, reaching inner radii. This would imply that part of the gas lying inside voids at a given time proceeds from overdense regions (e.g., clusters or filaments), where it could have been preprocessed, thus challenging the scenario of galaxy formation in voids, and dissenting from the idea of them being pristine environments.
Why Do M Dwarfs Have More Transiting Planets?
Authors: Mulders Gijs D. , Drążkowska Joanna , van der Marel Nienke , Ciesla Fred J. , Pascucci Ilaria 
Published: October 2021

Abstract
We propose a planet formation scenario to explain the elevated occurrence rates of transiting planets around M dwarfs compared to Sun-like stars discovered by Kepler. We use a pebble drift and accretion model to simulate the growth of planet cores inside and outside of the snow line. A smaller pebble size interior to the snow line delays the growth of super-Earths, allowing giant planet cores in the outer disk to form first. When those giant planets reach pebble isolation mass they cut off the flow of pebbles to the inner disk and prevent the formation of close-in super-Earths. We apply this model to stars with masses between 0.1 and 2 M
⊙ and for a range of initial disk masses. We find that the masses of hot super-Earths and of cold giant planets are anticorrelated. The fraction of our simulations that form hot super-Earths is higher around lower-mass stars and matches the exoplanet occurrence rates from Kepler. The fraction of simulations forming cold giant planets is consistent with the stellar mass dependence from radial-velocity surveys. A key testable prediction of the pebble accretion hypothesis is that the occurrence rates of super-Earths should decrease again for M dwarfs near the substellar boundary like Trappist-1.
Formation of Polar Terrestrial Circumbinary Planets
Authors: Childs Anna C. , Martin Rebecca G. 
Published: October 2021

Abstract
All circumbinary planets (CBPs) currently detected are in orbits that are almost coplanar to the binary orbit. While misaligned CBPs are more difficult to detect, observations of polar-aligned circumbinary gas and debris disks around eccentric binaries suggest that polar planet formation may be possible. A polar-aligned planet has a stable orbit that is inclined by 90° to the orbital plane of the binary with an angular momentum vector that is aligned to the binary eccentricity vector. With n-body simulations we model polar terrestrial planet formation using hydrodynamic gas disk simulations to motivate the initial particle distribution. Terrestrial planet formation around an eccentric binary is more likely in a polar alignment than in a coplanar alignment. Similar planetary systems form in a polar alignment around an eccentric binary and a coplanar alignment around a circular binary. The polar planetary systems are stable even with the effects of general relativity. Planetary orbits around an eccentric binary exhibit tilt and eccentricity oscillations at all inclinations; however, the oscillations are larger in the coplanar case than the polar case. We suggest that polar-aligned terrestrial planets will be found in the future.
A Multispecies Pseudoadiabat for Simulating Condensable-rich Exoplanet Atmospheres
Authors: Graham R. J. , Lichtenberg Tim , Boukrouche Ryan , Pierrehumbert Raymond T. 
Published: October 2021

Abstract
Central stages in the evolution of rocky, potentially habitable planets may play out under atmospheric conditions with a large inventory of nondilute condensable components. Variations in condensate retention and accompanying changes in local lapse rate may substantially affect planetary climate and surface conditions, but there is currently no general theory to effectively describe such atmospheres. In this article, expanding on the work by Li et al., we generalize the single-component moist pseudoadiabat derivation in Pierrehumbert to allow for multiple condensing components of arbitrary diluteness and retained condensate fraction. The introduction of a freely tunable retained condensate fraction allows for a flexible, self-consistent treatment of atmospheres with nondilute condensable components. To test the pseudoadiabat’s capabilities for simulating a diverse range of climates, we apply the formula to planetary atmospheres with compositions, surface pressures, and temperatures representing important stages with condensable-rich atmospheres in the evolution of terrestrial planets: a magma ocean planet in a runaway greenhouse state; a post-impact, late-veneer-analog planet with a complex atmospheric composition; and an Archean Earth-like planet near the outer edge of the classical circumstellar habitable zone. We find that variations in the retention of multiple nondilute condensable species can significantly affect the lapse rate and in turn outgoing radiation and the spectral signatures of planetary atmospheres. The presented formulation allows for a more comprehensive treatment of the climate evolution of rocky exoplanets and early Earth analogs.
Repercussion of Conventional Complete Mandibular Denture Versus Single Implant Over-Denture on Retention and Biting Force
Authors: Elsherbini Ahmed N. , Niedermeier Wilhelm 
Published: October 2021

Aim: Aim of this study was the evaluate the retention and biting force of conventional complete denture and after placement of a single implant in the mandible for an implant retained over-denture
Material and methods
Eight completely edentulous patients were selected. A single implant was inserted at the symphysis of the mandible and left to osseointergrate. During the osseointegration period a conventional complete denture was fabricated and inserted. Retention and biting force was measured at insertion and after 3 months of service. After osseointegration attachment was connected, space was formed in the fitting surface of the existing mandibular denture and retention silicon was placed. Retention and biting force were measured at insertion and after 3 months follow-up. Data were collected and statistically analyzed.
Results:
The retention mean values for the complete denture was 2.420±0.360, however the retention mean values for the single implant over-denture was 6.395±0.289. F=3.80 with statically significance difference between the groups of P <0.01. The biting force mean values for the complete denture was 52.62±2.71, however the biting force mean values for single implant over-denture was 71.45±2.73. F= 1.790 with statically insignificance difference between the groups of P >0.01
Conclusion:
Single implant overdenture improved the retention and the biting force when compared with the complete denture, this has improved the quality of life and happiness.

There have been several recent checklists, books and publications about Indian moths; however, much of this work has focused on biodiversity hotspots such as North-east India, Western Ghats and Western Himalayas. There is a lack of published literature on urban centres in India, despite the increased need to monitor insects at sites with high levels of human disturbance. In this study, we examine the moths of Delhi, the national capital region of India, one of the fastest growing mega-metropolitan cities. We present a comprehensive checklist of 338 moths species using 8 years of light trapping data (2012-2020) and examining about 2000 specimens from historical collections at the National Pusa Collection of ICAR-Indian Agricultural Research Institute, New Delhi (NPC-IARI) spanning over 100 years (1907-2020). The checklist comprises moths from 32 families spanning 14 superfamilies with Noctuoidea (48.5%) and Pyraloidea (20.4%) being the the two most dominant superfamilies. We provide links to images of live individuals and pinned specimens for all moths and provide detailed distribution records and an updated taxonomic treatment.This is the first comprehensive annotated checklist of the moths of Delhi. The present study adds 234 species to the biodiversity of moths from Delhi that were not reported previously, along with illustrations for 195 species.
Critical media literacy to improve students' competencies

Published: October 2021

Media literacy training is an urgent need of our time. Educational institutions must stand as fundamental domains to collectively address reflection on digital and media environments and prepare school-age citizens to constructively deal with the impact of the media. To do so, a paradigm shift to approach the issue is required: a critical awareness of the new scenarios created by the media and a broad reflection on their characteristics. A new framework where the spotlight is on the media, the surrounding environment is an essential reference point and training proposals are based on results and evidence. This study is part of a Design-Based Research, aimed at the creation, implementation and evaluation of a Critical Media Literacy program for high school students at the Escuela Normal Superior del Putumayo (Colombia). In this paper we present the results obtained by applying the Alfamed media competence "pre" and "post" questionnaire to the students participating in the program. The results obtained show a significant improvement both in the overall level of students' media competence and in four of the six dimensions that make up the theoretical reference model ("Technology", "Language", "Ideology and Values" and "Production and Dissemination").
La formación en las competencias mediáticas constituye una necesidad urgente en nuestra época. La escuela debe posicionarse como un entorno fundamental donde abordar de manera colectiva la reflexión sobre los entornos digitales y mediáticos y la preparación de los ciudadanos en edad escolar para afrontar de forma constructiva el impacto de los medios. Para ello, se impone un cambio de paradigma en el abordaje de la cuestión: una conciencia crítica ante los nuevos escenarios que crean los medios y una reflexión amplia sobre sus características. Un nuevo marco en el que lo mediático se torne central, el entorno próximo sea un referente imprescindible y las propuestas formativas se apoyen en resultados y evidencias. El trabajo que se presenta es una parte de una Investigación Basada en Diseño, orientada a la creación, implementación y evaluación de un programa de Alfabetización Mediática Crítica para el alumnado de bachillerato de la Escuela Normal Superior del Putumayo (Colombia). Se presentan los resultados obtenidos mediante la aplicación “pre” y “post” del cuestionario de competencias mediáticas Alfamed al alumnado participante en el programa. Los resultados obtenidos muestran una mejora significativa tanto en el nivel global de competencia mediática del alumnado, como en cuatro de las seis dimensiones que configuran el modelo teórico de referencia en el que se apoya el estudio (“Tecnología”, “Lenguaje”, “Ideología y Valores” y “Producción y difusión”).
