ANÁLISIS DE LAS CREENCIAS DE UN GRUPO DE ESTUDIANTADO UNIVERSITARIO MEXICANO SOBRE EL CONCEPTO DE ORIENTACIÓN SEXUAL
Authors: García Villanueva Jorge , Hernández Ramírez Claudia Ivonne , Gómez Palacios Juan Carlos 
Published: July 2024

La presente investigación tuvo como objetivo analizar las creencias de un grupo de estudiantes universitarios mexicanos sobre la orientación sexual (homosexualidad, bisexualidad y heterosexualidad). Se aplicaron redes semánticas naturales a través de cuatro estímulos. A partir del núcleo de las redes, se realizó un análisis cuantitativo mediante el uso de la prueba “ji cuadrada” y con base en los resultados derivados de la aplicación del estadístico se pudieron observar los valores de las definidoras, las coincidencias y las diferencias entre los géneros. Lo que se denota en los análisis es que el estudiantado considera que la orientación sexual tiene su origen en la biología, consideran que es una condición natural y que está determinada desde el nacimiento. Cuando aparecen otras manifestaciones sexuales son vistas como patologías que se deben curar, además atentan en contra de la reproducción y perpetuación de la especie humana o, simplemente, se miran como peligrosas y portadoras de infecciones de transmisión sexual. Este dato permite comprender que la sexualidad es diversa y que no existe una sola forma de ser ni de expresarla, pues cada persona lo hace con base en sus experiencias, emociones, sentimientos y placeres.
Sometimes memory misleads: Variants of the error-speed effect strengthen the evidence for systematically misleading memory signals in recognition memory
Authors: Voormann Anne , Rothe-Wulf Annelie , Meyer-Grant Constantin G. , Klauer Karl Christoph 
Published: July 2024

Abstract
The error-speed effect describes the observation that the speed of recognition errors in a first binary recognition task predicts the response accuracy in a subsequent two-alternative forced-choice (2AFC) task that comprises the erroneously judged items of the first task. So far, the effect has been primarily explained by the assumption that some error responses result from misleading memory evidence. However, it is also possible that the effect arises because participants remember and use their response times from the binary task to solve the 2AFC task. Furthermore, the phenomenon is quite new and its robustness or generalizability across other recognition tasks (e.g., a confidence-rating task) remains to be demonstrated. The aim of the present study is to address these limitations by introducing a new variant of the error-speed effect, replacing the 2AFC task with a confidence-rating task (Experiment 1), and by reversing task order (Experiment 2) to test whether participants employ a response-time strategy. In both experiments, we collected data using a sequential probability ratio t-test procedure and found evidence in favor of the hypothesis that the speed of binary recognition errors predicts confidence ratings for the same stimulus. These results attest to the robustness and generalizability of the error-speed effect and reveal that at least some errors must be due to systematically misleading memory evidence.

Published: July 2024

Polysarcosine emerges as a promising alternative to polyethylene glycol (PEG) in biomedical applications, boasting advantages in biocompatibility and degradability. While the self-assembly behavior of block copolymers containing polysarcosine containing polymers has been reported, their potential for shape transformation remains largely untapped, limiting their versatility across various applications.In this study, we present a comprehensive methodology for synthesizing, self-assembling, and transforming polysarcosine-polybenzylglutamate block copolymers, resulting in the formation of bowl-shaped vesicles, disks, and stomatocytes. Under ambient conditions, the shape transformation is restricted to bowl-shaped vesicles due to the membrane's flexibility and permeability. However, dehydration of the polysarcosine broadens the possibilities for shape transformation.These novel structures exhibit asymmetry and possess the capability to encapsulate smaller structures, thereby broadening their potential applications in drug delivery and nanotechnology. Our findings shed light on the unique capabilities of polysarcosine-based polymers, paving the way for further exploration and harnessing of their distinctive properties in biomedical research.

Published: July 2024

Abstract
Low-mass ratio systems (LMR) are a very interesting class of contact eclipsing binaries challenging the theoretical models of stability. These systems are also considered possible progenitors of the rare low-mass optical transients called red novae. In this study, we present the identification of 7 new totally eclipsing LMR systems from Catalina Sky Surveys (CSS) and 77 LMR candidates from the All Sky Automated Survey. Using the available CSS light curves and new multiband observations for CSS_J210228.3-031048 and CSS_J231513.3+345335 with the 2.3 m Aristarchos telescope at Helmos Observatory, we estimate their physical and absolute parameters and investigate their stability and their progenitors. The light curves are analyzed by performing a two-dimensional scan on the mass–ratio inclination plane with Phoebe-0.31 scripter, while the errors are estimated using Monte Carlo simulations and heuristic scanning of the parameter space. Our analysis revealed that all 9 CSS systems have extreme mass ratios from 0.09 to 0.16. Our statistical analysis of well-studied LMR contact binaries shows that LMR systems tend to have warmer and more massive primaries. The investigation of the progenitors of both low and higher-mass-ratio systems reveals a trend for the former to originate from higher-mass ancestors. Finally, we investigate the stability condition by calculating the ratio of spin angular momentum to orbital angular momentum and other stability indicators in the context of the reliability of the solutions.
Photometric Completeness Modelled with Neural Networks
Authors: Harris William E. , Speagle 沈 Joshua S. 佳士 
Published: July 2024

Abstract
In almost any study involving optical/near-infrared photometry, understanding the completeness of detection and recovery is an essential part of the work. The recovery fraction is, in general, a function of several variables including magnitude, color, background sky noise, and crowding. We explore how completeness can be modeled, with the use of artificial-star tests, in a way that includes all of these parameters simultaneously within a neural network (NN) framework. The method is able to manage common issues including asymmetric completeness functions and the bilinear dependence of the detection limit on color index. We test the method with two sample Hubble Space Telescope data sets: the first involves photometry of the star cluster population around the giant Perseus galaxy NGC 1275, and the second involves the halo-star population in the nearby elliptical galaxy NGC 3377. The NN-based method achieves a classification accuracy of > 94% and produces results entirely consistent with more traditional techniques for determining completeness. Additional advantages of the method are that none of the issues arising from the binning of the data are present and that a recovery probability can be assigned to every individual star in real photometry. Our data, models, and code (called COINTOSS) can be found online on Zenodo at the following link: https://doi.org/10.5281/zenodo.8306488.
Sensitivity of Polarization to Grain Shape. II. Aggregates
Authors: Draine B. T. 
Published: July 2024

Abstract
A previous study (Paper I) investigated the polarization properties of a variety of simple convex grain shapes, some of which were found to be consistent with the observed polarization properties of interstellar dust from far-ultraviolet to far-infrared. Here, we study the optical properties of 45 nonconvex shapes, all aggregates of N equal-sized spheres. We consider N = 2, N = 3, and N = 256 random aggregates obtained from three different aggregation schemes. We also consider “trimmed” N = 256 aggregates obtained by systematically trimming initially random aggregates to increase either flattening or elongation. The “macroporosities” of the studied aggregates range from

P

macro

=
0.18

(for the N = 2 bisphere) to

P

macro

≈
0.85

(for the N = 256 “BA” aggregates). The only aggregates consistent with observations of starlight polarization and polarized thermal emission are shapes that have been trimmed to increase their asymmetry. If interstellar grains are high-porosity aggregates, there must be processes causing extreme elongation or flattening; if not, interstellar grains must be dominated by fairly compact structures, with at most moderate porosities. The ratio of polarization in the 10 μm silicate feature to starlight polarization in the optical is shown to be insensitive to porosity and shape. X-ray scattering may be the best tool to determine the porosity of interstellar grains. We propose that modest porosities of interstellar grains could be the result of “photolytic densification.” High polarization fractions observed in some Class 0 cores require processes to reduce porosities and/or increase asymmetries of aggregates in dense regions.
Planetesimal Drift in Eccentric Disks: Possible Outward Migration
Authors: Silsbee Kedron 
Published: July 2024

Abstract
Radial drift of solid particles in the protoplanetary disk is often invoked as a threat to planet formation, as it removes solid material from the disk before it can be assembled into planets. However, it may also concentrate solids at particular locations in the disk, thus accelerating the coagulation process. Planetesimals are thought to drift much faster in an eccentric disk, due to their higher velocities with respect to the gas, but their drift rate has only been calculated using approximate means. In this work, we show that in some cases previous estimates of the drift rate, based on a modification of the results for an axisymmetric disk, are highly inaccurate. In particular, we find that under some easily realized circumstances, planetesimals may drift outwards, rather than inwards. This results in the existence of radii in the disk that act as stable attractors of planetesimals. We show that this can lead to a local enhancement of more than an order of magnitude in the surface density of planetesimals, even when a wide dispersion of planetesimal size is considered.

Published: July 2024

Abstract
We seek to understand the composition and variability of fast solar wind (FSW) and slow Alfvénic solar wind emerging from coronal holes (CHs). We leverage an opportune conjunction between Solar Orbiter and Parker Solar Probe (PSP) during PSP Encounter 11 to include compositional diagnostics from the Solar Orbiter Heavy Ion Sensor as these variations provide crucial insights into the origin and nature of the solar wind. We use potential field source surface and magnetohydrodynamic models to connect the observed plasma at PSP and Solar Orbiter to its origin footpoint in the photosphere and compare these results with the in situ measurements. A very clear signature of a heliospheric current sheet crossing as evidenced by enhancements in low first ionization potential (FIP) elements, ion charge state ratios, proton density, low Alfvénicity, and polarity estimates validates the combination of modeling, data, and mapping. We identify two FSW streams emerging from small equatorial CHs with low ion charge state ratios, low FIP bias, high Alfvénicity, and low footpoint brightness, yet anomalously low alpha particle abundance for both streams. We identify high-Alfvénicity slow solar wind emerging from the overexpanded boundary of a CH having intermediate alpha abundance, high Alfvénicity, and dips in ion charge state ratios corresponding to CH boundaries. Through this comprehensive analysis, we highlight the power of multi-instrument conjunction studies in assessing the sources of the solar wind.
Modeling of Granulation in Red Supergiants in the Magellanic Clouds with the Gaussian Process Regressions
Authors: Zhang 张 Zehao 泽浩 , Ren 任 Yi 逸 , Jiang 姜 Biwei 碧沩 , Soszyński Igor , Jayasinghe Tharindu 
Published: July 2024

Abstract
The granulation of red supergiants (RSGs) in the Magellanic Clouds is systematically investigated by combining the latest RSG samples and light curves from the Optical Gravitational Lensing Experiment and the All-Sky Automated Survey for Supernovae. The present RSG samples are first examined for foreground stars and possible misidentified sources, and the light curves are sequentially checked to remove the outliers by white noise and photometric quality. The Gaussian process (GP) regression is used to model the granulation, and the Markov Chain Monte Carlo is applied to derive the granulation amplitude σ and the period of the undamped oscillator ρ, as well as the damping timescale τ. The dimensionless quality factor Q is then calculated through Q = π
τ/ρ. RSGs around

are considered to have significant granulation signals and are used for further analysis. Combining granulation parameters with stellar parameters, robust scaling relations for the timescale ρ are established, while the scaling relations for amplitude σ are represented by a piecewise function, possibly related to the tendency of amplitudes in faint RSGs to converge toward a certain value. Comparing results between the Small Magellanic Cloud and the Large Magellanic Cloud confirms that amplitudes and timescales become larger with metallicity. In examining the scaling relations between the two galaxies, it is found that ρ is nearly independent of metallicity, whereas σ is more significantly affected by metallicity. The GP method is compared with the periodogram fitting of the granulations, and the advantages of either are discussed.
Discriminating between Babcock–Leighton-type Solar Dynamo Models by Torsional Oscillations
Authors: Zhong Congyi , Jiang Jie , Zhang Zebin 
Published: July 2024

Abstract
The details of the dynamo process in the Sun are an important aspect of research in solar-terrestrial physics and astrophysics. The surface part of the dynamo can be constrained by direct observations, but the subsurface part lacks direct observational constraints. The torsional oscillations, a small periodic variation of the Sun's rotation with the solar cycle, are thought to result from the Lorentz force of the cyclic magnetic field generated by the dynamo. In this study, we aim to discriminate between three Babcock–Leighton dynamo models by comparing the zonal acceleration of the three models with the observed one. The property that the poleward and equatorward branches of the torsional oscillations originate from about ±55° latitudes with their own migration time periods serves as an effective discriminator that could constrain the configuration of the magnetic field in the convection zone. The toroidal field, comprising poleward and equatorward branches separated at about ±55° latitudes, can generate the two branches of the torsional oscillations. The alternating acceleration and deceleration bands in time are the other property of the torsional oscillations that discriminates between the dynamo models. To reproduce this property, the phase difference between the radial (B

r
) and toroidal (B

ϕ
) components of the magnetic field near the surface should be about π/2.
Supernova Explosions of the Lowest-mass Massive Star Progenitors
Authors: Wang Tianshu , Burrows Adam 
Published: July 2024

Abstract
We here focus on the behavior of supernovae that technically explode in 1D (spherical symmetry). When simulated in 3D, however, the outcomes of representative progenitors of this class are quite different in almost all relevant quantities. In 3D, the explosion energies can be 2 to 10 times higher, and there are correspondingly large differences in the 56Ni yields. These differences between the 3D and 1D simulations reflect in part the relative delay to explosion of the latter and in the former the presence of protoneutron star convection that boosts the driving neutrino luminosities by as much as ∼50% at later times. In addition, we find that the ejecta in 3D models are more neutron-rich, resulting in significant weak r-process and 48Ca yields. Furthermore, we find that in 3D the core is an interesting, though subdominant, source of acoustic power. In summary, we find that though a model might be found theoretically to explode in 1D, one must perform supernova simulations in 3D to capture most of the associated observables. The differences between 1D and 3D models are just too large to ignore.
La coercition dans l’histoire du travail en Chine au début de l’époque moderne. Catégories et idées préconçues
Authors: Chevaleyre Claude , Goudarzi Tiam 
Published: July 2024

Cet essai critique invite les historiens de la Chine à réinvestir le champ de l’histoire de la coercition au début de l’époque moderne, de manière à réévaluer l’importance du travail contraint, mais aussi repenser les mondes sociaux des dynasties Ming et Qing. Si les historiens de la Chine ont toujours accordé une grande attention au travail et aux relations de travail, la coercition semble avoir quelque peu disparu des travaux récents. Ce manque relatif d’attention résulte principalement de l’abandon de l’accent, parfois excessif, mis sur les masses laborieuses en tant que victimes de l’exploitation « féodale ». Mais il est également la conséquence de l’utilisation d’une terminologie vague, de traductions hâtives et d’idées préconçues qui n’ont jamais été remises en question. Un consensus semble notamment s’être dégagé sur le fait que la société chinoise, depuis le xviii e siècle, aurait été dominée par un marché du travail libre. Nous soutenons que cette hypothèse découle de transpositions des cadres analytiques de l’Occident moderne non soumises à l’examen critique, et d’une représentation erronée des politiques des Qing visant les « sujets dégradés » ( jianmin ) et les « travailleurs à gages » ( gugong ).
Teaching E. E. Cummings’ No Thanks
Authors: Alfandary Isabelle 
Published: July 2024

The reading of a modernist book of poems such as No Thanks (1935) by E. E. Cummings is affected and impacted by what may be regarded as minor changes in the book presentation, such as the presence or absence of an introduction to the collection, as well as typographical modifications. In fact, editorial options often prove decisive in the reading experience. This article seeks to examine the material conditions that determine the reception of E. E. Cummings’ poetry in the classroom and beyond, inasmuch as it is based on visual and grammatical games.
De Processen van Istanboel
Authors: Ternon Yves 
Published: July 2024

In dit artikel worden de processen behandeld die gevoerd moesten worden tegen de verantwoordelijken voor de systematische uitroeiing van de Armeniërs tijdens de Eerste Wereldoorlog. Het toont aan dat het – vanaf de wapenstilstand van Moudros tot eind 1920 – de wil van opeenvolgende Ottomaanse regeringen was om hun eigen processen te organiseren, zodat ze niet moesten samenwerken met een tribunaal van de overwinnaars, waaraan ze officiële documenten zouden moeten overhandigen en Ottomaanse beschuldigden zouden moeten uitleveren. Finaal droegen de processen van Istanboel onweerlegbare bewijzen aan van een misdaad die na 1948 gekwalificeerd zou worden als de genocide op de Armeniërs.
How Climate Action Plans are modified by the energy crisis? A focus on residential heating in Bristol
Authors: Hatem Nicolas 
Published: July 2024

The recent surge in European energy prices could substantially reduce the social cost of Climate Action Plans. This paper conducts an ex-ante Cost-Benefit Analysis of mitigation policies in residential heating and studies the extent to which rising energy prices modifies their cost-effectiveness. I use the city of Bristol (UK) as a case study and assess two options: (1) investing in district heating networks in central districts or (2) subsidizing energy efficiency retrofits for least efficient dwellings. Implementing either of the two policy options under high energy prices trends increase economic benefits to households by around £ 1 per pound invested, in present value, relative to a scenario with baseline energy prices trends. Besides, district heating networks become more cost-effective at mitigating carbon emissions than energy efficiency retrofits.JEL classification: D61, Q41, Q48, Q58
