The Heavier the Faster: A Subpopulation of Heavy, Rapidly Spinning and Quickly Evolving Binary Black Holes
Authors: Guo Wei-Hua , Li Yin-Jie , Wang Yuan-Zhu , Shao Yong , Wu Shi-Chao , Zhu Tao , Fan Yi-Zhong 
Published: October 2024

Abstract
The spins of binary black holes (BBHs) measured from gravitational waves contain valuable information about their formation pathways. In this study, we propose a new quantity, the “dimensionless net spin” (χ
N), which relates to the sum of the angular momenta of the component black holes (BHs) in the system, offering a novel perspective for exploring the origins of BBHs. Through hierarchical Bayesian inference on χ
N, we find strong evidence that its distribution is better described by two Gaussian components rather than one, and their branching ratios vary with total mass and redshift: there is a narrow peak at χ
N ∼ 0.15 and an extended peak at χ
N ∼ 0.3–0.6. The rapidly spinning systems likely dominate the high-mass end of the population and evolve with redshift more quickly. These findings present new challenges to the field binary formation scenario and suggest that dynamical processes may play a key role in the formation of high total mass BBHs.

Abstract
The proximity of the Large and Small Magellanic Clouds (LMC and SMC) provides the opportunity to study the impact of dwarf–dwarf interactions on their mass assembly with a unique level of detail. To this end, we analyze two-filter broadband imaging of 83 Hubble Space Telescope (HST) pointings covering 0.203 deg2 toward the SMC, extending out to ∼3.5 kpc in projection from its optical center. Lifetime star formation histories (SFHs) fit to each pointing independently reveal an outside-in age gradient such that fields in the SMC outskirts are older on average. We measure radial gradients of the look-back time to form 90%, 75%, and 50% of the cumulative stellar mass for the first time, finding δ(τ

) Gyr kpc−1 assuming PARSEC evolutionary models and a commonly used elliptical geometry of the SMC, although our results are robust to these assumptions. The wing of the SMC deviates from this trend, forming 25% of its cumulative mass over the most recent 3 Gyr owing to a best-fit star formation rate that remains approximately constant. Our results are consistent with chemodynamical evidence of a tidally stripped SMC component in the foreground and imply contributions to the observed SFH from multiple previous LMC–SMC interactions. We also compare our SMC SFH with results from a companion study of the LMC, finding that while the two galaxies present different internal, spatially resolved SFH trends, both the LMC and SMC have similar near-constant lifetime SFHs when viewed globally.
A Two-zone Accretion Disk in the Changing-look Active Galactic Nucleus 1ES 1927+654: Physical Implications for Tidal Disruption Events and Super-Eddington Accretion

Published: October 2024

Abstract
The properties of slim accretion disks, while crucial for our understanding of black hole growth, have yet to be studied extensively observationally. We analyze the multiepoch broadband spectral energy distribution of the changing-look active galactic nucleus 1ES 1927+654 to derive the properties of its complex, time-dependent accretion flow. The accretion rate decays as

was characterized by a low radiation efficiency (3%), which later more than doubled (8%) after

dropped sufficiently low for the disk to transition to a geometrically thin state. The blackbody temperature profile T ∝ R
−0.60 for the inner overheated zone matches the theoretical expectations of a slim disk, while the effective temperature profile of T ∝ R
−0.69 for the outer zone is consistent with the predictions of a thin disk. Both profiles flatten toward the inner boundary of the disk as a result of Compton cooling in the corona. Our work presents compelling observational evidence for the existence of slim accretion disks and elucidates the key parameters governing their behavior, paving the way for further exploration in this area.
An Edge-on Regular Disk Galaxy at z = 5.289
Authors: Yan Haojing , Sun Bangzheng , Ling Chenxiaoji 
Published: October 2024

Abstract
While rotation-supported gas disks are known to exist as early as at z ≈ 7, it is still a general belief that stellar disks form late in the Universe. This picture is now being challenged by the observations from the James Webb Space Telescope (JWST), which have revealed a large number of disk-like galaxies that could be at z > 3, with some being candidates at z > 7. As an early formation of stellar disks will greatly impact our theory of galaxy formation and evolution, it is important to determine when such systems first emerged. Here we present D-CEERS-RUBIES-z5289 at z = 5.289 ± 0.001, the second confirmed stellar disk at z > 5, discovered using the archival JWST NIRCam imaging and NIRSpec spectroscopic data. This galaxy has a highly regular edge-on disk morphology, extends to ∼6.2 kpc along its major axis, and has an effective radius of ∼1.3–1.4 kpc. Such a large stellar disk is yet to be produced in numerical simulations. By analyzing its 10-band spectral energy distribution using four different tools, we find that it has a high stellar mass of 109.5–10.0
M
⊙. Its age is in the range of 330–510 Myr, and it has a mild star formation rate of 10–30 M
⊙ yr−1. While the current spectroscopic data do not allow the derivation of its rotation curve, the width of its Hα line from the partial slit coverage on one side of the disk reaches ∼345 km s−1, which suggests that it could have a significant contribution from rotation.
Towards EU Nature Restoration Law: a Boost for Biodiversity and Climate?
Authors: Baran Mariusz 
Published: October 2024

The Nature Restoration Law, which was proposed on 22 June 2022 by the European Commission, would require European Union Member States to revive forests, wetlands and other sea – and landscapes marred by human development. The proposal tabled includes legally binding restoration targets for various ecosystems across the EU, and offers a huge opportunity to put our degraded nature on the path toward recovery. Support for a strong and ambitious EU Nature Restoration Law from the Member States will be crucial to maintain the overall ambition level of the legislation. Recovering our degraded ecosystems, and above all those with the most potential for capturing and storing carbon, is key to achieving the EU’s climate and biodiversity goals, as well as its international commitments. The proposal adds a new level of legal strength to conservation and restoration efforts across Europe. Previous attempts to increase restoration have failed, both in the EU Biodiversity Strategy to 2020, and the global strategic plan for biodiversity to 2020. The overarching objective of the proposed law is to achieve continuous, long term and sustained recovery of biodiverse land and sea areas, and increase climate mitigation and adaptation through restoration. Nature-based solutions should be a cornerstone of these ongoing efforts. This chapter has identified: (i) the aim of the proposed law, (ii) legally binding targets for Member States, (iii) no ‘one-size-fits-all’ concept and consideration of the strengths and weaknesses of the proposed regulation.
Soul-foods as pharmaka: female bodies and poisons in the Upper Rio Negro
Authors: Lolli Pedro , Andrello Geraldo 
Published: October 2024

In this article, we explore the origins, properties, and ritual uses of a series of psychoactive substances among indigenous peoples of the Upper Rio Negro. Setting out from the mythical genesis of tobacco, coca, paricá, and caapi (ayahuasca), we examine the relationship between these substances and diverse aspects of female bodies and their reproductive powers, suggesting that these psychoactives can be conceived as pharmaka in the classic sense of the term, acting both to increase a person’s vital force and/or to harm and kill. As we show, these effects relate to the practice of blown magical incantations, used to both cure and provoke diseases, a connection that allows us to explore indigenous notions of life force, speech, and breath as ways through which bodies affect each other.
Love and anger in Amazonia and in academia: a disciple’s account of Joanna Overing’s oeuvre and teachings
Authors: Sulkin Carlos D. Londoño 
Published: October 2024

In the Caquetá, Colombia, in 1995, I asked an Englishman who was doing fieldwork for his Ph.D. at Oxford for advice about graduate studies in the UK. “Maybe consider going to Joanna Overing,” he recommended. He thought that she and her students were doing the most exciting research in Amazonianist anthropology at the time. Meeting him was the first in a chain of fortunate events that led to my doing a Ph.D. under Joanna’s supervision and witnessing a golden but embattled era in her career. This is my personal account of her loves and peeves, her generous supervisory style, her theories, and her place in the history of our discipline and regional specialization, as I now see these. Regarding the latter, I focus especially on her brilliant writing on how contingent associations of Western anthropologists’ analytical terms hinder proper understanding of others’ political philosophies and ways of life; I attend as well to her attention to the centrality of moral understandings in social life, and to her participation in debates about Amazonian engagements with alterity, consanguinity, and conviviality.

Published: October 2024

Neste artigo exploramos as contribuições de Joanna Overing à etnologia das Terras Baixas da América do Sul, em diálogo com os principais temas teóricos abordados pela subdisciplina. Neste sentido, propomos uma breve biografia intelectual da antropóloga norte-americana, nascida em 1938, que fez trabalho de campo na Venezuela, lecionou nos Estados Unidos, na Inglaterra e na Escócia, teceu diálogos interdisciplinares entre filosofia, linguística e antropologia e dinamizou as trocas entre a etnologia feita na Inglaterra, na França, na Escandinávia e no Brasil. Sendo a única mulher no Departamento de Antropologia da London School of Economics durante boa parte da década de 1980, Overing enfrentou polêmicas pioneiras sobre parentesco, gênero, racionalidade, temporalidade, estética e criatividade com uma escrita elegante, clara e teoricamente densa, abrindo espaço para outras mulheres na academia. Tanto em Londres, como em Saint Andrews, ela fez escola. Teve muitos orientandos e orientandas e com eles e elas definiu pautas-chave para futuros desenvolvimentos da antropologia.

Abstract. We examine results from two transient modeling experiments that simulate the Last Interglacial period (LIG) using the state-of-the-art Community Earth System Model (CESM2), with a focus on climate and ocean changes relevant to the possible collapse of the Antarctic ice sheet. The experiments simulate the early millennia of the LIG warm period using orbital forcing, greenhouse gas concentrations, and vegetation appropriate for 127 ka. In the first case (127ka), no other changes are made; in the second case (127kaFW), we include a 0.2 Sv freshwater forcing in the North Atlantic. Both are compared with a pre-industrial control simulation (piControl). In the 127ka simulation, the global average temperature is only marginally warmer (0.004 °C) than in the piControl. When freshwater forcing is added (127kaFW), there is surface cooling in the Northern Hemisphere (NH) and warming in the Southern Hemisphere (SH), consistent with the bipolar seesaw effect. Near the Antarctic ice sheet, the 127ka simulation generates notable ocean warming (up to 0.4 °C) at depths below 200 m compared to the piControl. In contrast, the addition of freshwater in the North Atlantic in the 127kaFW run results in a multi-century subsurface ocean cooling that rebounds slowly over multiple millennia near the Antarctic ice sheet. These results have implications for the thermal forcing (and thereby mass balance) of the Antarctic ice sheet. We explore the physical processes that lead to this result and discuss implications for climate forcing of Antarctic ice sheet mass loss during the LIG.

El presente artículo es el resultado del proyecto de investigación que asumió como propósito investigar en el contexto de la economía de Colombia los modelos emergentes de Administración empresarial al albor de la teoría de las organizaciones que se autogestionan, con el fin de determinar en las MiPymes la viabilidad práctica de implementar un modelo ajustado a la realidad de la gestión empresarial que en ellos se efectúa. La investigación que se realizó fue de tipo exploratoria, dado que sirve para preparar el terreno, usualmente antecede a los otros tipos de investigación; de su objeto de estudio se tomó como población las Pymes de los sectores manufacturero, comercial y de servicios, ubicadas en las ciudades de Medellín, Bogotá y Cali, para una muestra aleatoria estratificada de 4.640 empresas, donde se realizaron encuestas de tipo formal estructurado, con las cuales se efectuó un análisis cualitativo para darle respuesta a la investigación con sus respectivas conclusiones. Los resultados de la investigación muestran que la realidad de las MiPymes latinoamericanas presentan debilidades y fragilidades, acompañadas de diseños organizacionales tradicionales, siendo en esta área de predominio el empirismo como práctica cotidiana, ante lo cual los modelos emergentes se perciben como el cambio respuesta necesario para dar a estas organizaciones la dimensión adecuada a los desafíos y retos que en el mundo actual se presentan.
Simulações em Python: uma alternativa para o ensino de física
Authors: Pinto Odeilson Morais , Heredia Jardel Reis , Gonçalves Rosana Alves 
Published: October 2024

Simulações computacionais oferecem experiências visuais e interativas, substituindo métodos tradicionais de ensino. Considerando a escassez de laboratórios didáticos de Física nas escolas de nível médio do país, as simulações são uma importante ferramenta para o ensino dessa disciplina, sendo capazes de fornecer uma visualização dos fenômenos descritos na teoria. Este trabalho tem como objetivo apresentar uma simulação didática em Python para explorar conceitos físicos, em particular o lançamento oblíquo. A linguagem Python foi escolhida por ser referenciada como uma linguagem de programação fácil e acessível, a qual pode ser utilizada por um iniciante, sem conhecimento prévio avançado de programação. Através da simulação proposta, os usuários podem observar o movimento oblíquo de um projétil e fazer previsões de alcance e a altura, além de observar sua trajetória e entender a relação entre velocidade inicial, ângulo de lançamento e alcance. O código usado para criação da simulação é apresentado passo-a-passo, para que os usuários possam replicá-lo e/ou alterá-lo, bem como as instruções para instalação das bibliotecas. A sequência didática proposta pode enriquecer o ensino, promovendo a interdisciplinaridade entre Física e Informática. A abordagem envolve diretamente os alunos, tornando-os protagonistas do processo de ensino-aprendizagem, o que pode aumentar seu interesse pelo conteúdo. A proposta ainda evidencia como o uso das tecnologias da informação e da comunicação (TICs) podem ser importantes aliadas para a construção de uma aprendizagem mais dinâmica e significativa mediando abordagens interdisciplinares em sala de aula.
SUSTAINABILITY OF POTATO FARMS IN THE LIMA REGION
Authors: Contreras-Liza Sergio , Muñoz Alberto Valenzuela , Ardián Luis Baldeos 
Published: October 2024

Objective: This study aims to evaluate the sustainability of the potato-producing farms and to propose management alternatives for optimising the potato production system under the conditions of the central coast of Peru.

Theoretical Framework: Potato is a native crop from Peru with a wide genetic diversity and is currently developed in small farms in more than 300 thousand hectares nationwide. This production generates rural employment therefore it is important to evaluate the sustainability of the production system by agronomic practices that are environmentally friendly.

Method: Social, economic, and environmental sustainability levels of potato farms were assessed through the multicriteria analysis, using a survey as the research tool for 127 potato producers in the provinces of Barranca, Huaral, and Cañete (Lima) evaluating the effect of microbial inoculation on the sustainability of the potato production system afterwards.

Results and Discussion: It was determined that the potato-producing farms in the Lima region have a low level of sustainability with a value of 1.76 on the weighted scale of indicators used and that it is necessary to implement measures that reduce the vulnerability of the potato crop in terms of soil life conservation and agrobiodiversity management.

Research Implications: Regarding the sociocultural aspect of this research, the inadequate degree of social integration and the low level of environmental awareness were constraining factors in achieving sustainability. Significant differences were obtained from the inoculation strategy of seed tubers with microbial strains when compared to control plots in experimental conditions.

Originality/Value: It is concluded that the use of growth-promoting microbes in potatoes can be a management alternative to reduce the vulnerability of the crop, increasing the low level of sustainability found in potato production farms in the central coast of Peru.
