DISTRIBUTION AND VARIATION OF NET PRIMARY PRODUCTIVITY IN FORESTLAND AND GRASSLAND OF CHINA
Authors: Shi J , Cui L.L.
Published: May 2024

Net primary productivity (NPP) can characterize the state and service functions of terrestrial ecosystems and reflect the responses of plants to climate fluctuations and human disturbances. Many studies have analysed changes in NPP and its influencing factors in some parts of China, but few studies have made in-depth comparisons between different regions, decades, and land cover types across China. Based on uniform NPP products and land cover data, the distribution, difference and variation of NPP in forestland and grassland in China were investigated with GIS spatial analysis and least-squares regression methods, and results indicated that average NPP increased gradually from northwest to southeast, and the regions with average NPP of 1-200 gC m-2 yr-1 occupied the largest proportion. During 1981–2018, the regions where decadal average NPP increased were larger than those where NPP decreased, and the areas with inter-decadal difference of 1-50 gC m-2 yr-1 were the largest. In different land cover types or regions, NPP generally exhibited a rapid rising trend in the 1990s and a slow or declining trend in the 2000s. Annual NPP increased at a rate of 13.2 gC m-2 decade-1 in the entire study area during 1981–2018, and the NPP in forestland and grassland increased at a speed of 15.6 and 11.1 gC m-2 decade-1, respectively. Spatially, NPP increased at a rate of 1-100 gC m-2 decade-1 in most areas, and the increasing trend was statistically significant in Qinghai-Tibetan Plateau, most of Northwest China and eastern Northeast China. The area with a significant increase in NPP over the past 38 years accounted for 21.0% of the total study area. Our results highlight the consistent and upward variation of NPP in general, but there are some distinctions among different land cover types and different regions of China, and higher quality datasets and more reliable methods should be fully explored in further studies.
Keywords: Net primary productivity, spatial distribution, linear trend, forestland and grassland, China.
EXPRESSION ANALYSIS OF ML237, R2R3 MYB AND OIL_143 GENES THAT AFFECT THE COLD TOLERANCE DURING THE COLD-HARDENING STAGE ON SUCCESSFUL CRYOPRESERVATION OF MENTHA × PIPERITA L.
Authors: Galatali S , Zengin T , Kaya E
Published: May 2024

Mentha × piperita L., one of the oldest known hybrid species, was formed by the derivation of M. spicata L. and M. aquatica L. Since the plant is a hybrid species, it has sterile seeds and can be propagated vegetatively. The fact that the plant grown in natural and field environments is affected by biotic and/or abiotic environmental conditions keeps the continuity of the species under pressure and this situation requires the germplasm of the plant to be protected as an alternative. The current study aimed to investigate the expressions of ML237, R2R3 MYB and oil_143 genes determined by the bioinformatics blast studies that were effective against the cold tolerance in the M. × piperita at transcriptional level during the cold-hardening which is one of the cryopreservation treatment stages. With this study, it is aimed to obtain basic information that can be useful in cryopreservation studies for these and similar plants to be carried out in the future, and in biotechnological applications to increase viability and regeneration after cryo-storage. According to the T-Test result after the statistical evaluation of the results, a significant increases were observed the ML237, R2R3 MYB and oil_143 genes.

FNDC5 IS THE KEY MOLECULE TO INHIBIT MUSCLE FIBER DEVELOPMENT IN TIBETAN PIGS
Authors: Xie X , Yan F , Wu H , Wu G , Yin Y , Duan M , Chamba Y , Shang P
Published: May 2024

Differences in muscle fiber development between Tibetan and Yorkshire pigs determine their performance in terms of meat quality, taste, and food value. To investigate the molecular regulation of muscle fiber development by fibronectin type III domain-containing protein 5 (FNDC5), a preliminary study of FNDC5 gene expression in the longissimus dorsi muscle and Leg muscle tissues of Tibetan and Yorkshire Pigs was conducted using RT–qPCR and western blotting. Muscle tissues were sectioned and stained to observe the muscle fiber diameter and area under a microscope. The mRNA and protein expression levels of FNDC5, and the diameter and area of muscle fibers in the longissimus dorsi muscle and Leg muscle tissues of Tibetan pigs were significantly lower than those in Yorkshire Pigs. The results imply that FNDC5 negatively regulates muscle fiber diameter in pigs. The role of FNDC5 in pork quality has important implications for improving pork production efficiency, pork quality, and the sustainable development of the livestock industry.
Keywords: Pig; FNDC5; Gene expression.

Imágenes y cuerpos del ñandú (Rhea americana) en las celebraciones de los qom
Authors: Robledo Emilio
Published: May 2024

Based on the ethnography of qom (toba) communities living on the right bank of the middle Bermejo River, in the ArgentineChaco, I address the relationship of this people with the ñandú (Rhea americana), a bird native to South America and closelylinked to the hunting tradition in the Gran Chaco. I argue that beyond the hunting activity, this relationship is inscribed in the Chaco landscape, in the memories, cosmology and celebrations of the qom people. This case is framed by the contemporary anthropological debate on the classic opposition between practices and ethos of domestication and hunting, that I approach from the context of indigenous feasts and their ability to congregate in the same space-time human relations and prominent links with plant and animal species. I conclude that the qom’s proximity to the images and body of ñandú, beyond turning the bird into an object of human hunting or significance, allowed them to understand the way of dealing with transformations configured by the alternation between abundance and scarcity, as extremes that shape the landscape and life in the Chaco.
El cambio climático y el desasosiego animal en la cordillera de Vilcanota, Perú
Authors: Caine Allison
Published: May 2024

Este artículo examina el impacto del cambio climático en las comunidades andinas de la sierra través del lente de las relaciones entre personas y animales. Los pastores andinos y sus animales coproducen formas jerárquicas, cooperativas y antagónicas de interacción social, mediadas a través de la comunicación entre personas y animales. Considerando las condiciones de sequía frecuente y las interrupciones en los patrones de migración estacional, el quiebre en las prácticas comunicativas entre personas y animales alerta a los pastores de los cambios socioecológicos más extensos. Muestro esta dinámica al seguir la cadena de eventos que causan las interrupciones: primero, a medida que surge en los encuentros diarios de pastoreo y luego, a medida que se extiende e impacta las discusiones a nivel comunitario sobre el futuro del pastoreo en la sierra de los Andes. Me baso en el lenguaje de pastoreo del quechua y tradiciones mitológicas quechuas para mostrar cómo las prácticas de microinteracción entre personas y animales reflejan un entendimiento más amplio de las jerarquías dentro de la socialidad junto con sus límites en las ontologías andinas, y a su vez brindan información sobre los procesos localizados de fragmentación socioecológica iniciados por cambios en el clima. Sugiero que el concepto andino de desasosiego o inquietud (k’ita) provee de una analítica provocativa para evaluar los impactos del cambio climático global.
Judeoconversos entre Lima y Cartagena
Authors: Navarrete María Cristina
Published: May 2024

The Portuguese Jewish converts who settled in the viceroyalty of Peru were dedicated to the trade of slaves, merchandise and handicraft activities. The Inquisition, under the pretext of preserving Christianity, pursued causes of faith against them.This was linked to the need for funds for the operation of the Lima Inquisition, the crisis between Spain and Portugal and the fear of allying with the Dutch enemy. The research problem is related to the persecution of the Inquisition against the new Christians accusing them of Judaizing and the punishment they received. Forty were condemned to the galleys in Spain; when they arrived in Cartagena, they evaded the authorities. The article relies conceptually and methodologically on microhistory and highlights the historiographic narrativeto transmit knowledge.

Published: May 2024

Depuis un an environ, les performances des modèles de prévision du temps basés sur les réseaux de neurones sont devenues suffisamment intéressantes pour que les prévisionnistes commencent à les considérer. À l'occasion du passage de la tempête Ciaràn sur l'ouest de la France, nous évaluons les qualités et les défauts de quatre d'entre eux : GraphCast (Google Deepmind), Pangu-Weather (Huawei), AIFS (Centre européen pour les prévisions météorologiques à moyen terme, CEPMMT) et FourCastNet (Nvidia). Nous montrons que, loin encore de la prévision opérationnelle, les modèles de prévision par intelligence artificielle proposent des informations très pertinentes pour anticiper les tempêtes violentes.

Over the past year or so, the performance of neural network-based weather forecasting models has progressed significantly and began to attract the interest of forecasters. At the occasion of the passage of the Ciaràn storm over western France, we evaluate the strengths and shortcomings of four of them: GraphCast (Google Deepmind), Pangu-Weather (Huawei), AIFS (European Center for Medium-Range Weather Forecasts, ECMWF) and FourCastNet (NvIDIA). We show that, although far from being operational, artificial intelligence-based forecasting models are able to propose useful information to anticipate damaging storms.

Lėtinė obstrukcinė plaučių liga ir gretutinės ligos. LOPL paūmėjimų prevencija ir mirštamumo mažinimas
Authors: Biekšienė Kristina
Published: May 2024

Lėtinė obstrukcinė plaučių liga (LOPL) daro didelę įtaką pacientų gyvenimo kokybei, o ligos paūmėjimai padidina tiesiogines ir netiesiogines sveikatos priežiūros išlaidas. Pacientai, sergantys LOPL, vidutiniškai serga penkiomis skirtingomis lėtinėmis ligomis, kurios dažnai lieka nediagnozuotos ir negydytos. LOPL paūmėjimo metu sergantiesiems ypač padidėja sunkių širdies ir kraujagyslių ligų rizika. Triguba budezonido, glikopironio ir formoterolio (BUD, GLY ir FORM) terapija viename inhalitoriuje sumažino sergančiųjų vidutinio sunkumo, sunkia arba labai sunkia LOPL mirties riziką dėl visų priežasčių; taip pat šis derinys siejamas su kardiopulmoninės rizikos prevencija, veiksmingu paūmėjimų mažinimu. Greitas trigubos BUD, GLY ir FORM terapijos skyrimas po paūmėjimo gali užtikrinti mažesnę gretutinių ligų riziką ir daryti reikšmingą poveikį ilgalaikėms baigtims. Labai svarbu LOPL diagnozuoti ir gydyti kuo anksčiau, numatant paūmėjimų prevencijos priemones, stebėti dėl širdies, plaučių ir kitų ligų pasireiškimo po LOPL paūmėjimo.

Going back to “basics”: Harlow’s learning set task with wolves and dogs
Authors: Rivas-Blanco Dániel , Monteiro Tiago , Virányi Zsófia , Range Friederike
Published: May 2024

To survive and reproduce, animals need to behave adaptively by adjusting their behavior to their environment, with learning facilitating some of these processes. Dogs have become a go-to model species in comparative cognition studies, making our understanding of their learning skills paramount at multiple levels, not only with regards to basic research on their cognitive skills and the effects of domestication, but also with applied purposes such as training. In order to tackle these issues, we tested similarly raised wolves and dogs in a serial learning task inspired by Harlow’s “learning set.” In Phase 1, different pairs of objects were presented to the animals, one of which was baited while the other was not. Both species’ performance gradually improved with each new set of objects, showing that they “learnt to learn,” but no differences were found between the species in their learning speed. In Phase 2, once subjects had learned the association between one of the objects and the food reward, the contingencies were reversed and the previously unrewarded object of the same pair was now rewarded. Dogs’ performance in this task seemed to be better than wolves’, albeit only when considering just the first session of each reversal, suggesting that the dogs might be more flexible than wolves. Further research (possibly with the aid of refined methods such as computer-based tasks) would help ascertain whether these differences between wolves and dogs are persistent across different learning tasks.
Tools and methods to study and replicate experiments addressing human social cognition in interactive scenarios
Authors: Marchesi Serena , De Tommaso Davide , Kompatsiari Kyveli , Wu Yan , Wykowska Agnieszka
Published: May 2024

In the last decade, scientists investigating human social cognition have started bringing traditional laboratory paradigms more “into the wild” to examine how socio-cognitive mechanisms of the human brain work in real-life settings. As this implies transferring 2D observational paradigms to 3D interactive environments, there is a risk of compromising experimental control. In this context, we propose a methodological approach which uses humanoid robots as proxies of social interaction partners and embeds them in experimental protocols that adapt classical paradigms of cognitive psychology to interactive scenarios. This allows for a relatively high degree of “naturalness” of interaction and excellent experimental control at the same time. Here, we present two case studies where our methods and tools were applied and replicated across two different laboratories, namely the Italian Institute of Technology in Genova (Italy) and the Agency for Science, Technology and Research in Singapore. In the first case study, we present a replication of an interactive version of a gaze-cueing paradigm reported in Kompatsiari et al. (J Exp Psychol Gen 151(1):121–136, 2022). The second case study presents a replication of a “shared experience” paradigm reported in Marchesi et al. (Technol Mind Behav 3(3):11, 2022). As both studies replicate results across labs and different cultures, we argue that our methods allow for reliable and replicable setups, even though the protocols are complex and involve social interaction. We conclude that our approach can be of benefit to the research field of social cognition and grant higher replicability, for example, in cross-cultural comparisons of social cognition mechanisms.
Clausura y comensalidad en Pajchela núcleo (Cusi Cusi, Puna de Jujuy). La excavación del recinto 2
Authors: Carreras Jesica
Published: May 2024

En este trabajo se presentan los resultados e interpretaciones de las excavaciones del Recinto 2 del sitio arqueológico Pajchela Núcleo, ubicado en la localidad de Cusi Cusi (Puna de Jujuy, Argentina). La excavación de este recinto presentó un contexto complejo, con el hallazgo de más de diez mil huesos de camélidos junto con una gran cantidad de rocas de variados tamaños y, por debajo, el techo quemado de la estructura. Se ha interpretado como un evento de clausura mediante un incendio y el arrojado de los restos de una comida colectiva al interior de la estructura. El sitio Pajchela Núcleo se caracteriza por la presencia de un gran montículo plataforma escalonado con cámaras, estructuras chullparias y espacios de producción agrícola, y ha sido interpretado como un lugar de memoria. El hallazgo de este evento de clausura signado por la comensalidad colectiva, refuerza esta interpretación y permite pensar a Pajchela Núcleo como un espacio de encuentro y reunión.

Published: May 2024

The article reveals aspects of the situation on the global LNG market in the context of sanctions pressure on Russian LNG enterprises, and suggests ways for Russian LNG enterprises to adapt to these conditions. The conditions of sanctions pressure on Russian LNG enterprises are described and the impact of sanctions on the LNG industry is revealed. The conducted research is based on statistical data from Russian and foreign sources. Aspects of the global LNG market environment include: an increase in the scale of LNG production in the world, the use of innovative gas liquefaction technologies, the development of a system for organizing and managing the transportation of liquefied gas, an increase in the number of states purchasing LNG for their needs, changes in the volume of LNG production and consumption in the world. The analysis presented in the article of the prospects and directions of development of this market in the future, as well as the main economic and technical factors influencing its functioning, and its conditions over the past five years have shown that this market is actively developing. The authors come to the conclusion: Russian LNG exporting enterprises have managed to adapt to the current competitive market conditions of global LNG trade, diversify their capacities and transport logistics, and have also significantly expanded the possibilities of transporting LNG along the Northern Sea Route.

Published: May 2024

The article examines the situation with the staffing of socially oriented non-profit organizations that has developed in Russia in recent years. The relevance of the affected issues is due to the high importance of the activities of subjects of the non-profit sector of the economy to ensure the economic and social development of Russia. The methodology of the research conducted in the article is based on a statistical analysis of quantitative data reflecting the current situation in the field of staffing of socially oriented non-profit organizations. Based on the results of the analysis, a conclusion is drawn about the downward dynamics of the number of socially oriented non-profit organizations employees (and, accordingly, the insufficiency of their current number to ensure the development of the tertiary sector of the economy). Separately, there is a decrease in the level of public involvement in the functioning of the subjects of the non-profit sector of the economy, which is recorded on the basis of data on the nature of changes in the number of employees. The practical significance of the conducted research lies in the substantiation by the authors of the need to develop the personnel policy of socially oriented non-profit organizations based on the results of a detailed analysis of the relevant indicative indicators, as well as in the development of appropriate recommendatory measures. Thus, the organization of personnel work with volunteers, who, according to the authors, are more likely to be able to join staff of socially oriented non-profit organizations than representatives of other categories of potential employees, is positioned as the main direction of transformation of this area. In addition, the positive effect of the organization of internships by socially oriented non-profit organizations for students and graduates of secondary and higher professional education institutions is emphasized, which will allow potential employees to familiarize themselves with the goals of socially oriented non-profit organizations and their key values.

The presented article reflects a study of the state of the housing construction market in recent years. The article offers a brief analysis of the state of bibliographic study of the issue of the state of the competitive environment in the housing construction and residential real estate market, reflects the systematization and description of five main trends, provides a more detailed analysis of the state of the competitive environment and the structure of the housing commodity market, calculates indicators reflecting the fact of structural dominance in the regions of the Russian Federation. A ranking of the 20 largest developers in terms of “housing under construction” and the regions of their presence in 2023 and a comparative analysis of structural changes in market concentration by federal districts for the period 2021–2023 were built. The level of concentration of housing construction markets according to the indicator “housing under construction” in the context of administrative-territorial districts of the Russian Federation is determined. It is noted that in most regions of Russia there is a high level of competition in the residential real estate construction market, which has a significant impact on the state of the market as a whole and the processes taking place on it. The presence of active competition in 85% of regional housing construction markets indicates that there are no signs of abuse of a dominant position in the vast majority of regions, signs of structural collective dominance are also limited, which allows us to hypothesize that price increases are formed not because of the monopolistic behavior of real estate developers, but due to the influence of other factors, which are subject to more detailed study.
Institute of “Nominal Manager of the Company”: Essence, Forms, Motives and Risks of Application
Authors:   Synergy University, Osipenko Oleg V.
Published: May 2024

The article is a multidimensional study of the institution of figurehead in the contexts of Russian corporate governance, legal regulation and judicial enforcement. Applying analytical methods of scientific research to analyze the institution of figurehead, the author seeks to consider various aspects of this institution, including its essence, forms, motives for use, punishability and associated risks. The work reveals the approach of Russian judicial practice to the definition of a “nominal leader” as a formal, not actual leader. The author hypothesizes that shadow corporate governance is one of the subsystems of the domestic shadow economy, and that “nominal management of the company’s operating practices” is a class of diverse structures, the generation of one part of which pursues frankly destructive goals in social terms, the other is situationally reasonable. Analyzing scientific publications, legislative acts, and judicial practice, the authors reveal individual forms of nominal management of a company: nominal shareholder, nominal company, nominal corporate act, nominal member of the board of directors, “multi-machine operator”, “technical premier”, member of the family business team, the executor of the instructions of the team of actual leaders, the textbook nominal director and situational-transit versions of the nominal leadership. The article highlights the risks of using forms of figurehead: a fundamental change in law enforcement practice, loss of time for management approvals, loss of confidential information, reputational and entrepreneurial, loss of business, withdrawal of assets and raider takeover. Administrative-legal, expert and corporate approaches are described in the discussion about the limits of punishment for “nominalities”, emphasizing the paradoxical nature of the institutional interpretation of the phenomenon of nominalities. In general, the article offers a broad scientific and applied discussion on interdisciplinary methodological grounds.

Published: May 2024

A discriminação de raça e sexo no mercado de trabalho é um fator marcante e importante na determinação das desigualdades de rendimentos brasileira. Esta desigualdade tem alguns determinantes, entre eles estão características que indicam produtividade dos indivíduos como escolaridade e experiência, e outras características que são meramente discriminatórias como gênero e raça. A desigualdade causada pelas diferenças de produtividade é identificada, neste trabalho, como efeito dotação e a causada por fatores discriminatórios de efeito discriminação. O objetivo é medir quanto da desigualdade de renda entre os grupos de raça/gênero é explicada pela discriminação e pela diferença de habilidades dos trabalhadores, analisando ainda como estes efeitos se comportam em diferentes quintis salariais. Para isto foram utilizadas as seguintes metodologias: curvas de probabilidade, decomposição de Oaxaca-Blinder (1973) e decomposição de Machado e Mata (2005). A análise foi realizada para o Brasil e para as cinco regiões brasileiras, a partir dos dados das PNADs de 2002, 2006 e 2009. Os principais resultados são: i) o grupo mais discriminado é o de mulheres não brancas, seguido de mulheres brancas e homens não brancos; ii) pelas curvas de probabilidade a discriminação de raça e de gênero tem um formato de “U”, sendo a maior discriminação no primeiro e último quintil exceto para o Sul e Sudeste onde a discriminação é crescente nos quintis salariais; iii) queda da diferença salarial entre os grupos entre 2002 e 2009; iv) toda a diferença salarial entre gêneros é explicada pela discriminação, efeito dotação contribui para a queda da diferença salarial; v) quanto maior o quintil de renda maior é representatividade discriminação na explicação da diferença entre os gêneros; vi) na discriminação racial, ambos os fatores, discriminação e dotação agem para aumentar a diferença salarial; vii) fator mais importante para determinar a diferença salarial entre grupos raciais: dotação; viii) a diferença salarial racial é crescente quanto maior o quintil; ix) a discriminação racial é menos importante para determinar a diferença de renda quanto maior o quintil no Brasil, o inverso é encontrado para as regiões.

Resum

La inseguretat econòmica està lligada als vincles emocionals i a les dificultats per a desenvolupar la identitat pròpia. Aquesta realitat és més evident pel que fa a les dones, ja que el mercat laboral està regulat per valors patriarcals, com mostren alguns còmics espanyols contemporanis amb un enfocament de gènere.
Temporada de collita
(2020) d’Ángel Abellán i Alba Flores és un bon exemple de com les novel·les gràfiques promouen la reflexió sobre l’experiència femenina en el capitalisme depredador, ja que posa de manifest les estratègies de col·laboració entre diverses generacions de dones. Aquesta història aborda dos tipus de crisi: d’una banda, la crisi laboral sistèmica, especialment perjudicial per a les dones, i de l’altra, la crisi d’identitat, a través del xoc de tres generacions amb diferents orígens i expectatives.

New BVR photometric and high-resolution spectroscopic observations of V505 Lac are presented with Transiting Exoplanet Survey Satellite (TESS) photometric data. The orbital period has experienced a secular decrease during the past 16 yr. A clear anticorrelation in the primary and secondary eclipse timing variation (PSETV) obtained from the TESS data is also identified. A double-lined radial velocity (RV) curve is secured, and the effective temperatures of the less- and more-massive stars (Stars 1 and 2, respectively) are measured. Using a spectral subtraction technique, excess emissions are detected in the time-series Ca ii H and K and Hα lines for Star 2. Simultaneous analysis of the light and RV curves using the Wilson–Devinney (WD) code reveals that V505 Lac is a photospherically and chromospherically active W-subtype contact binary system. The component-star masses and radii are determined to an accuracy of approximately 1%. The WD spot model is individually applied to 221 light curves segmented from the TESS data so as to derive the spot parameters of a cool spot on Star 2. The combined variations in both longitude and colatitude among the spot parameters appear to be strongly associated with those of both the anticorrelation in the PSETV and the O’Connell effect in the TESS light curves. Robust negative linear relationships between the PSETV anticorrelation size and the O’Connell effect magnitude are found for the first time. Mass–radius, mass–luminosity, and mass ratio–mass diagrams of contact binaries, along with the mass ratio frequency distribution, are presented in an attempt to elucidate the evolutionary characteristics of these systems.

We present the most precise constraints to date for the mass and age distributions of single ultracool dwarfs in the solar neighborhood, based on an updated volume-limited sample of 504 L, T, and Y dwarfs within 25 pc. We develop a Monte Carlo approach using the

We use our resulting luminosity function and a likelihood-based population synthesis approach to simultaneously constrain the mass and age distributions. We employ the fraction of young L0–L7 dwarfs as a novel input for this analysis that is crucial for constraining the age distribution. For a power-law mass function

we find β = −0.44 ± 0.14, i.e., a population with fewer old objects than often assumed, which may reflect dynamical heating of the Galactic plane as much as the historical brown dwarf birthrate. We compare our analysis to that of Kirkpatrick et al., who used a similar volume-limited sample. Although our mass function measurements are numerically consistent, their assumption of a flat age distribution is disfavored by our analysis, and we identify several important methodological differences between our two studies. Our calculation of the age distribution of solar neighborhood brown dwarfs is the first based on a volume-limited sample.
The Impact of Extended H2O Cross Sections on Temperate Anoxic Planet Atmospheres: Implications for Spectral Characterization of Habitable Worlds

Published: May 2024

JWST has created a new era of terrestrial exoplanet atmospheric characterization, and with it, the possibility to detect potential biosignature gases like CH4. Our interpretation of exoplanet atmospheric spectra, and the veracity of these interpretations, will be limited by our understanding of atmospheric processes and the accuracy of input modeling data. Molecular cross sections are essential inputs to these models. The photochemistry of temperate planets depends on photolysis reactions whose rates are governed by the dissociation cross sections of key molecules. H2O is one such molecule; the photolysis of H2O produces OH, a highly reactive and efficient sink for atmospheric trace gases. We investigate the photochemical effects of improved H2O cross sections on anoxic terrestrial planets as a function of host star spectral type and CH4 surface flux. Our results show that updated H2O cross sections, extended to wavelengths >200 nm, substantially impact the predicted abundances of trace gases destroyed by OH. The differences for anoxic terrestrial planets orbiting Sun-like host stars are greatest, showing changes of up to 3 orders of magnitude in surface CO levels, and over an order of magnitude in surface CH4 levels. These differences lead to observable changes in simulated planetary spectra, especially important in the context of future direct-imaging missions. In contrast, the atmospheres of planets orbiting M-dwarf stars are substantially less affected. Our results demonstrate a pressing need for refined dissociation cross-section data for H2O, where uncertainties remain, and other key molecules, especially at mid-UV wavelengths >200 nm.
Kinematic Age of the β-Pictoris Moving Group
Authors: Lee Jinhee , Song Inseok
Published: May 2024

Accurate age estimation of nearby young moving groups (NYMGs) is important as they serve as crucial testbeds in various fields of astrophysics, including the formation and evolution of stars and planets, as well as loose stellar associations. The β-Pictoris moving group (BPMG), being one of the closest and youngest NYMGs, has been extensively investigated, and its estimated ages have a wide range from ∼10–25 Myr, depending on the age estimation methods and data used. Unlike other age dating methods, kinematic traceback analysis offers a model-independent age assessment hence the merit in comparing many seemingly discordant age estimates. In this study, we determine the kinematic ages of the BPMG using three methods: probabilistic volume calculation, mean pairwise distance calculation, and covariance matrix analysis. These methods yield consistent results, with estimated ages in the range of 14–20 Myr. Implementing corrections to radial velocities due to gravitational redshift and convectional blueshift increases the ages by ∼2–4 Myr. Conversely, considering data uncertainties decreases the estimated ages by 1–2 Myr. Taken together, our analysis determined the kinematic age of the BPMG to be

Myr. This age is significantly younger than the commonly accepted age of the BPMG (∼24 Myr) determined primarily from the lithium depletion boundary analysis. This younger kinematic age may point to the discrepancy between the luminosity evolution and lithium depletion models or the presence of unaccounted systematic error in the method. This result underscores the necessity for systematic reevaluations of age-dating methods for nearby, young moving groups.
Pickup Ion Modulation on Plateau-like Turbulence in the Martian Magnetosheath

Published: May 2024

The distribution of magnetic energy across scales, represented by the turbulence spectrum, provides insights into magnetic field dynamics in astrophysical and space plasma. While the Earth’s magnetosheath exhibits a conventional two-slope spectrum, the Martian magnetosheath often displays a prominent plateau-like spectrum. However, the underlying physical mechanism remains unresolved. Based on MAVEN observations, we present appealing evidence of pickup ions (PUIs) modulating the plateau-like spectrum through proton cyclotron waves (PCWs). PCWs, driven by unstable pickup H+ ion distributions, significantly influence the formation of plateau-like spectra. Both case and statistical studies suggest that the spectral evolution is affected by the relative abundance of pickup O+ ions. A substantial presence of pickup O+ ions can suppress PCWs driven by pickup H+ ions, resulting in a decline in the slope of the plateau spectrum. Particle-in-cell simulations confirm the role of PUI-modulated PCWs in the plateau-range energy injection. Our results provide new insight into the impact of PUIs on magnetic turbulence evolution and associated energy transfer processes in space and astrophysical plasma.
A Recipe for Eccentricity and Inclination Damping for Partial-gap Opening Planets in 3D Disks
Authors: Pichierri Gabriele , Bitsch Bertram , Lega Elena
Published: May 2024

In a previous paper, we showed that, like the migration speed, the eccentricity damping efficiency is modulated linearly by the depth of the partial gap a planet carves in the disk surface density profile, resulting in less efficient e-damping compared to the prescription commonly used in population synthesis works. Here, we extend our analysis to 3D, refining our e-damping formula and studying how the inclination damping efficiency is also affected. We perform high-resolution 3D locally isothermal hydrodynamical simulations of planets with varying masses embedded in disks with varying aspect ratios and viscosities. We extract the gap profile and orbital damping timescales for fixed eccentricities and inclinations up to the disk scale height. The limit in gap depths below which vortices appear, in the low-viscosity case, happens roughly at the transition between classical type-I and type-II migration regimes. The orbital damping timescales can be described by two linear trends with a break around gap depths ∼80% and with slopes and intercepts depending on the eccentricity and inclination. These trends are understood on physical grounds and are reproduced by simple fitting formulas whose error is within the typical uncertainty of type-I torque formulas. Thus, our recipes for the gap depth and orbital damping efficiencies yield a simple description for planet–disk interactions to use in N-body codes in the case of partial-gap opening planets that is consistent with high-resolution 3D hydrosimulations. Finally, we show examples of how our novel orbital damping prescription can affect the outcome of population synthesis experiments.
