Published: July 2023

AbstractThe voice is a variable and dynamic social tool with functional relevance for self-presentation, for example, during a job interview or courtship. Talkers adjust their voices flexibly to their situational or social environment. Here, we investigated how effectively intentional voice modulations can evoke trait impressions in listeners (Experiment 1), whether these trait impressions are recognizable (Experiment 2), and whether they meaningfully influence social interactions (Experiment 3). We recorded 40 healthy adult speakers’ whilst speaking neutrally and whilst producing vocal expressions of six social traits (e.g., likeability, confidence). Multivariate ratings of 40 listeners showed that vocal modulations amplified specific trait percepts (Experiments 1 and 2), which could be explained by two principal components relating to perceived affiliation and competence. Moreover, vocal modulations increased the likelihood of listeners choosing the voice to be suitable for corresponding social goals (i.e., a confident rather than likeable voice to negotiate a promotion, Experiment 3). These results indicate that talkers modulate their voice along a common trait space for social navigation. Moreover, beyond reactive voice changes, vocal behaviour can be strategically used by talkers to communicate subtle information about themselves to listeners. These findings advance our understanding of non-verbal vocal behaviour for social communication.

Three-brain methodology: the way to achieve the Ecuadorian high school graduate's exit profile
Authors: Soto Grau Grisel de la Concepción 
Published: July 2023

This article presents the three brains methodology proposed by Waldemar De Gregori as a way to obtain the exit profile of the Ecuadorian high school graduate and, consequently, access to higher education and a better preparation for life. A bibliographic review of projects that apply this methodology in different educational institutions is carried out in order to promote the development of skills such as leadership, teamwork, scientific research and innovation, among others. This research, with a qualitative approach, suggests the renewal of traditional methodological strategies for a methodology that allows the holistic development of the student and that enhances the values of the Ecuadorian high school graduate's exit profile.
The Inner 2 pc of Sagittarius A*: Simulations of the Circumnuclear Disk and Multiphase Gas Accretion in the Galactic Center
Authors: Solanki Siddhant , Ressler Sean M. , Murchikova Lena , Stone James M. , Morris Mark R. 
Published: July 2023

Abstract
The inner few parsecs of the Milky Way’s Galactic center contain the central accreting supermassive black hole, over a million stars, and multiple large gaseous structures. In the past, the structures at these length scales have generally been modeled independently of each other. It is consequently not well understood how these complex features interact with each other, nor how gas flows between the outer few parsecs and the inner subarcsecond region (1″ ≈ 0.04 pc). In this work, we present hydrodynamic simulations of the inner few parsecs of the Galactic center that, for the first time, combine a realistic treatment of stellar winds and the circumnuclear disk (CND) as they interact with the gravitational potential of the nuclear star cluster and Sagittarius A*. We observe interactions of the stellar winds with the inner edge of the CND, which leads to the growth of instabilities, induced accretion of cool gas from the inner edge of the disk, and the eventual formation of a small accretion disk of ∼104–105 K within r ∼ 0.1 pc. The formation of an inner disk qualitatively agrees with observations. This disk grows in radial extent and mass with time on ≳10 kyr timescales, with a growth rate of

Published: July 2023

Abstract
A bright fireball observed on 2020 November 7, over Scandinavia, produced the first iron meteorite with a well-determined pre-atmospheric trajectory. We calculated the orbit of this meteoroid and found that it demonstrates no close affinity with the orbit of any known asteroid. We found that the meteoroid (or its parent body) most probably entered the near-Earth orbit from the main asteroid belt via either ν
6 secular resonance with Saturn (89%) or 3:1 mean-motion resonance with Jupiter (11%). The long YORP timescale of the meteoroid suggests that it could have been produced in the main asteroid belt and survived the journey to the near-Earth orbit.
The Advanced Spectral Library: The Evolution of Chromospheric Wind Characteristics from Noncoronal to Hybrid Giant Stars*
Authors: Nielsen Krister E. , Airapetian Vladimir S. , Carpenter Kenneth G. , Rau Gioia 
Published: July 2023

Abstract
The Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph treasury program Advanced Spectral Library enables investigations of the characteristics and dynamics of the wind and chromosphere of cool stars using high-quality spectral data. This paper shows how the wind features change with spectral class when transferring across the Linsky–Haisch dividing line by comparing the noncoronal M3.5 giant γ Cru with the K5 hybrid γ Dra. We compare the presence of high-ionization diagnostics in the two objects in addition to the prominent wind spectrum in predominantly singly ionized species. We study the intrinsic strength and variation of the numerous Fe ii profiles observed in the near-ultraviolet HST spectrum that are sensitive to the wind opacity, turbulence, and flow velocity. The Fe ii relative strengths and wavelength shifts between the absorption and emission components reflect the acceleration of the wind from the base of the chromosphere. Furthermore, we have modeled the wind spectra using the SEI code to derive terminal velocities, wind acceleration, and mass-loss rates. Our results indicate that the chromosphere is denser when moving toward the hybrid objects. The derived average mass-loss rates in the two objects are similar but with a significantly greater terminal wind velocity and acceleration in the hybrid star. We present the analysis of the outflowing wind characteristics when transitioning from the cool noncoronal objects toward the warmer objects with chromospheric emission from a hotter environment.

P1 bands for classical fundamental-mode Cepheids in the Milky Way. We used a relatively modest number of 76 stars for the PL and 84−85 stars for the PW relations calibration. The data for the project were collected with the network of 40 cm telescopes of the Las Cumbres Observatory, and Gaia Data Release 3 parallaxes were used for the calculations. These gri-band PL and PW relations calibrations will be a useful tool for distance determinations in the era of large sky surveys using the Sloan photometric system, especially with the near-future start of the Large Synoptic Survey of Space and Time.
Searching for Radio Outflows from M31* with VLBI Observations

Published: July 2023

Abstract
As one of the nearest and most dormant supermassive black holes (SMBHs), M31* provides a rare but promising opportunity for studying the physics of black hole accretion and feedback at the quiescent state. Previous Karl G. Jansky Very Large Array (VLA) observations with an arcsecond resolution have detected M31* as a compact radio source over centimeter wavelengths, but the steep radio spectrum suggests optically thin synchrotron radiation from an outflow driven by a hot accretion flow onto the SMBH. Aiming to probe the putative radio outflow, we conducted milliarcsecond-resolution very long baseline interferometric (VLBI) observations of M31* in 2016, primarily at 5 GHz and combining the Very Long Baseline Array, Tianma 65 m, and Shanghai 25 m radio telescopes. Despite the unprecedented simultaneous resolution and sensitivity achieved, no significant (≳3σ) signal is detected at the putative position of M31* given an rms level of 5.9 μJy beam−1, thus ruling out a pointlike source with a peak flux density comparable to that (∼30 μJy beam−1) measured by the VLA observations taken in 2012. We disfavor the possibility that M31* has substantially faded since 2012, in view that a 2017 VLA observation successfully detected M31* at a historically high peak flux density (∼75 μJy beam−1 at 6 GHz). Instead, the nondetection of the VLBI observations is best interpreted as the arcsecond-scale core being resolved out at the milliarcsecond scale, suggesting an intrinsic size of M31* at 5 GHz larger than ∼300 times the Schwarzschild radius. Such extended radio emission may originate from a hot wind driven by the weakly accreting SMBH.

Pomegranate is a fruit with potential for exploitation in the Brazilian Northeast as medicine and food. However, the qualitative and quantitative scarcity of water resources is common in this region, requiring the use of water with high salt contents in irrigated agriculture. The adoption of strategies to reduce the harmful effects of salt stress in plants is therefore necessary, and foliar nitrogen (N) fertilization is a promising alternative. The objective of the work, therefore, was to evaluate the photochemical and phytomass aspects of pomegranate seedlings grown under irrigation water salinity and foliar nitrogen fertilization. The experiment was performed in a randomized block design, in an incomplete factorial scheme, with five levels of electrical conductivity of irrigation water - ECw (0.50, 1.15, 2.75, 4.35 and 5.00 dS m-1) and five nitrogen doses - N (0.0, 0.33, 1.15, 1.97 and 2.30 g L-1), totaling nine combinations, generated by the Central Composite Design, with four repetitions and two plants per repetition. Foliar N application at a dose of 1.37 g L-1 increased the production of leaf and root dry phytomass at 90 days after emergence. Salt stress reduced the photochemical activity and phytomass production of pomegranate seedlings, while there was a stimulus by increasing N application up to 2.3 g L-1.

Published: July 2023

The aetiology may be complex in patients presenting with fever and rash. The differential diagnosis may include coronavirus disease 2019 (COVID-19) infection, an adverse effect of the COVID-19 vaccine, infection, and vasculitis. We reported a patient who presented with fever and vasculitic rash, which we hypothesized was an adverse vaccine effect. A 35-year-old male patient presented to the emergency department reporting headache, fever, rash, weakness, and myalgia. The first dose of the mRNA vaccine, COVID-19, had been administered five days before his presentation. A nasopharyngeal severe acute respiratory syndrome coronavirus two-challenge test was negative. Antinuclear antibody, antineutrophil cytoplasmic antibody, rheumatoid factor, and cryoglobulin were negative. No hypocomplementemia was detected. Skin biopsy was predominantly lymphocytic, with a vasculitic reaction with a few neutrophils. The Rickettsia conorii immunoglobulin M test examined using enzyme-linked immunosorbent assay (ELISA) was positive. COVID-19 should be excluded in patients with fever, rash, and headache. Symptoms that occur after vaccination may indicate adverse reactions. Even though we are in the pandemic phase, rickettsiosis should not be forgotten.

Key Points
•	COVID-19 is suspected first in the patient who applied to the emergency department with the complaints of fever and maculopapular rash during the pandemic era.
•	Although the COVID-19 vaccine is widely used, possible side effects of the vaccine may raise doubts among physicians and patients.
•	The preliminary diagnosis of a patient with a vasculitic rash who complains of fever and myalgia should be thought to be Rickettsiosis.

Implementación de casos de prueba negativos en actividades VPL de Moodle
Authors: Carmona del Barco Pablo , Fernández Muñoz J. Álvaro , Perea Ortega José M. 
Published: July 2023

VPL (Virtual Programming Lab) es un plugin de Moodle que permite automatizar la evaluación del código de un programa escrito en un determinado lenguaje de programación. Actualmente, VPL solo permite configurar casos de prueba positivos durante la evaluación, es decir, posibilita mostrar un mensaje de error al estudiante cuando la salida del programa difiere de la esperada para cada caso. Esto limita la identificación del tipo de error cometido y su consecuente retroalimentación, ya que podrían existir problemas para los que sea conveniente comprobar si se obtiene una salida específica que no debería darse y que estaría motivada por algún error que se está cometiendo en el programa. Este trabajo presenta una mejora para paliar esta limitación que consiste en incluir casos de prueba negativos en el proceso de evaluación de VPL, de manera que también se pueda mostrar un mensaje de error cuando la salida del programa coincida con la configurada para cada uno de los errores previstos en el problema a resolver. Dicha mejora facilita al docente la identificación de errores previsibles en el código que entrega el estudiante y permite, en cierto modo, orientarle hacia el tipo de error cometido sin que este conozca el caso de prueba que lo provocó.
