Published: November 2024

Nasopharyngeal carcinoma (NPC), particularly prevalent in regions such as Malaysia, is a significant health concern often linked to Epstein-Barr virus (EBV) infection. The EBV nuclear antigen 1 (EBNA1), crucial for EBV survival and NPC tumorigenicity, has emerged as a potential therapeutic target for EBV-positive NPC. In this study, we utilized quantitative structure-activity relationship (QSAR) models to predict potential inhibitors of EBNA1. These models were developed based on the molecular fingerprints of known EBNA1 inhibitors, using both classification and regression approaches. Our QSAR classification models demonstrated consistently high precision, recall, F1 score, and accuracy scores across the training set. The top-performing models, constructed using logistic regression algorithms, achieved perfect precision scores of 1.000 in the test set evaluation. These models’ recall, F1 score, and accuracy scores were 0.571, 0.727, and 0.667, respectively. On the other hand, the best-performing model among the regression models was built using the sequential minimal optimization regression algorithm, achieving a correlation coefficient of 0.703. The mean absolute error and root mean square error of this QSAR regression model were 0.173 and 0.217, respectively, whereas the relative absolute error was 0.689. We screened the enamine advanced compound library using this regression model to predict compounds with potential EBNA1 inhibitory effects. This led to the identification of the top 10 compounds with the most promising predicted EBNA1 inhibitory properties.

Published: November 2024

As the average life expectancy continues to rise, the prevalence of multimorbidity is also expected to increase, potentially leading to outcomes such as functional decline, a higher risk of premature death, and adverse effects on overall health and well-being. This study aimed to estimate the survival rates of older adults with varying levels of health-related quality of life (HRQoL) and to assess the association between the domains and components of the 36-item Short Form Health Survey and all-cause mortality over a 10-year period in Brazil. We conducted a retrospective longitudinal study using baseline data from 1,520 elders (aged 60 years and older) who participated in the Health Care Survey of the Municipality of Campinas, São Paulo, Brazil (ISACamp 2008/2009). A linkage was established between the ISACamp databases and the Mortality Information System. An active search was performed for individuals whose data could not be paired to confirm the death status. Survival functions were calculated using the Kaplan–Meier method, while hazard ratios (with 95% confidence intervals) were determined using Cox regression analysis. All HRQoL domains showed proportional hazards and statistically significant differences (p < 0.05) between survival curves, except for the bodily pain domain. In the multivariate analysis, lower scores in physical functioning and role-physical were associated with a 74% and 42% increased risk of death, respectively. In addition, impairments in role-emotional, mental health, and general health heightened the risk of mortality by approximately 36%. Notably, the lowest score in the physical component emerged as a significant predictor of mortality, increasing the probability of death by 47%, while the mental component showed no significant association. Our findings provide compelling evidence of the predictive capacity of HRQoL in evaluating mortality risk among older people in low- and middle-income countries.

"Todo trem da Supervia tem um pouco de navio negreiro":
Authors: Firmino dos Santos Douglas , Oliveira Dandara
Published: November 2024

Observando interações que constituem o cotidiano brasileiro, levantamos o seguinte questionamento: o colonialismo ainda interfere profundamente nas realidades racializadas de nosso país? Visando responder a essa pergunta, o presente texto se propõe a refletir acerca do Brasil atual analisando relações entre vida cotidiana e escravidão articuladas por vozes racializadas. Debruçamo-nos sobre narrativas que significam situações do dia a dia como encenações coloniais em virtude de entextualizações da escravidão. As análises apontam que o arquivo colonial vem sendo iterado no Brasil contemporâneo através de performances racistas que são contestadas por pessoas racializadas que negociam e disputam sentidos a respeito delas, recontextualizando acontecimentos diários. De tal modo, entendemos que tais narrativas abordam a escravidão não como uma banalidade, ou um mero processo histórico, mas como uma incessante ameaça à vida de corpos negros.
DÁ UMA UMBIGADA NA OUTRA:

Published: November 2024

Resumo: Sob uma constelação audiovisual em que a linguagem dos corpos baila em cena, convocando-os uns aos outros, entendemos este gesto de leitura, como um movimento semelhante à umbigada. Imbricado à metodologia das constelações fílmicas (SOUTO, 2019) e em cruzo (RUFINO, 2018), atravessado pelo território e suas sensibilidades, propomos uma reflexão sobre a movência do samba de roda como forma de circulação de sentido e emergência de imagens decoloniais, trazido à cena acadêmica para tirar para dançar outras perspectivas. Neste conjunto de interações, observamos incorporações de dimensões do sensível, nem sempre visibilizadas, entre agentes humanos e não-humanos (ambientais, tecnológicos, espirituais). O movimento circular da umbigada entre corporalidades nos reconecta com práticas e subjetividades comunitárias amefricanas, ameríndias, periféricas, da ancestralidade brasileira, sobretudo ligadas ao feminino.

Sensitive character, melancholic type, and extras on personality and mental disorders
Authors: Viotti Daker Maurício
Published: November 2024

A traditional view in psychiatry concerns the intimate relationship between personality disorders and primary mental disorders in a spectral model. Psychic functions with common roots might play a role in personality and psychosis or other disorders, probably not only in terms of deficits but also balance or proportions among them. Personality characteristics in connection with endogenous or functional psychoses are described, such as the sensitive and melancholic types. Concepts derived from psychopathology, namely schizoidism and syntony, which involve psychosis and personality, seem related to pivotal frameworks in cognitive sciences comprising the so-called 4Es. When adopting a continuum view of mental disorders, they behave in a unitary or systemic configuration, corresponding to endogenous-functional dispositions interacting with the milieu and composing personality.
Psicoterapia, psicopatologia e liberdade de ser
Authors: Luiz Socreppa da Fonseca Fábio
Published: November 2024

O presente texto se trata de uma discussão a respeito do emprego do conceito de condições de possibilidade advindo da Psicopatologia Fenomenológica para além da compreensão da estrutura da consciência para se pensar a intervenção psicoterapêutica em uma perspectiva fenomenológica. Para esse fim a condição de liberdade é discutida em relação a como o humano é abordado em diferentes formas de psicoterapia, destacando a condição de negatividade da liberdade em uma compreensão existencial. Discute-se a necessidade de ampliar a dialogicidade da psicoterapia fenomenológica com perspectivas contemporâneas que se fundamentam no mesmo horizonte conceitual como a própria Psicopatologia Fenomenológica e a posição externalista da consciência presente na posição enactivista da cognição. Por fim, a discussão a respeito da intervenção clínica é realizada a partir de uma vinheta clínica de uma pessoa com estrutura borderline. Compreende-se que esse texto não esgota a necessidade de se pensar a intervenção clínica que considere as condições de possibilidade em uma perspectiva psicoterapêutica, mas que incite mais produções nesse sentido.
Amor em Ellen West
Authors: De Castro Gazotti Thais
Published: November 2024

Este ensaio aborda o caso de Ellen West, destacando a relação entre o amor e a anorexia nervosa sob a ótica da psicopatologia fenômeno-estrutural. Ellen ansiava pelo amor, simbolizado por calor e vitalidade, mas o medo de engordar incitou a restrição alimentar e exercícios excessivos. Os desconfortos, provenientes da intersubjetividade, estabelecem o mundo vivido, com o qual concorda e discorda ao mesmo tempo; traz à tona a espacialidade em suas dimensōes dialéticas, principalmente a verticalidade-horizontalidade; e requer a intercorporeidade, que prevê a existência do eu num corpo sujeito e objeto. Ellen sente-se atravessada pela interpessoalidade e objetificada ao ser olhada, percebida e julgada. Sua conexão com seu mundo vivido encontrava-se absente da presença de corpos objetos, levantando a temática da sexualidade mínima ou inexistente nos casos de anorexia nervosa. Este caso expõe a complexa relação ter um corpo e ser um corpo para viver as relações intersubjetivas.

Conflation between ‘Public Good’ and ‘Greater Good’ in the Context of Research Impact
Authors: Brauer René , Dymitrow Mirek
Published: November 2024

Abstract This study sets out to conceptually distinguish between ‘public’ and ‘greater good’ in respect to research impact claims. We argue that the former is a category reflective of genuine benefit for the wider public, while the latter
merely represents a rhetorical category to pursue the ends of a select few. Methodologically, we showcase that only within the actual research conduct is it possible to distinguish between these two categories. Likewise, without acknowledging methodological limitations, researchers may contribute
to post-truth predicaments in the sense that the interaction ritual chains they are using constitute a mere rhetorical flourish rather than a rigorous argument for genuine benefit. We conclude with an appeal to future scrutiny for how researchers can retain their integrity in this new research
impact discourse. We argue that an uncritical use of impact arguments may undermine the very social fabric that makes scientific pursuits possible.
Critical Subjectivization: From Docile, Ascetic Bodies to Polyglots in Foreign Language Education in Higher Education
Authors: Lü Chieh
Published: November 2024

Abstract This paper revisits Michel Foucault’s ideas about subjectivity, its applications to understand foreign language education, and, importantly, its learners in higher education. The paper argues that Foucault’s ideas about subjectivization were grounded
primarily in his related concept of disciplinary societies; while today, the government of human subjects in higher education have shifted to forms of governance better described as control societies – an extension layered upon disciplinary societies. If control is overlooked when examining
foreign language learners’ subjectivities, it perpetuates an ascetic register of the self that language learners must implicitly navigate under the governance of control societies. As a result, the paper argues that an ascetic register of the self limits the possibilities of dynamically
becoming different subjects. The paper concludes by arguing that adding ideas about ‘nomadic-subjects’ with Foucault’s ideas of subjectivity is a more comprehensive framework from which to understand foreign language learners’ subjectivities.

Authors: Niaz Hina , Alam Khan Asaf
Published: November 2024

OBJECTIVES
This study aimed to evaluate the efficiency of the B-Lynch compression suture for primary post-partum hemorrhage control.
METHODOLOGY
It is a prospective cross-sectional study performed for two years, i.e., 1 November 2021 to 31 October 2023, at the Department of Obstetrics and Gynaecology in a tertiary care hospital. This study included 65 study cases out of 23,964 with primary post-partum hemorrhage (PPH) due to uterine atony during cesarean delivery not responding to pharmacological treatment and was managed by applying B-Lynch compression sutures. The amount of blood loss, demographic characteristics, birth weight of babies, causative factors, and other related complications were studied in such selected cases.
RESULTSB-Lynch compression suture presented a success rate of 97% in the present study. 52% had blood loss of 1000-1500ml, 29% had loss between 1501-2000ml and 18% had 2001-2500ml blood loss. 6% had wound gaping, 10.7% had a fever, and 8% had more than seven days stay in hospital, and wound infections were noted.
CONCLUSION
Our study concluded that the B-Lynch compression suture had a success rate of 97% in the management of primary post-partum hemorrhage, with few post-operative complications. The current research demonstrates the efficacy of B-Lynch as a lifesaving, easy, effectual technique that avoids hysterectomy and thus avoids heavy blood loss.

Authors: Ahmad Siddique , Iftikhar Muhammad , Muhammad Saadia , Uddin Zubair , Khan Muhammad Bilawal
Published: November 2024

OBJECTIVES
To assess the effectiveness of retro pyloric Roux-En-Y Hepaticojejunostomy in cases of choledochal cysts and bile duct injuries to reduce complications, such as delayed gastric emptying and acute cholangitis.
METHODOLOGY
This retrospective cohort study was conducted in the surgical C unit of Hayatabad Medical Complex, Peshawar (January 2019 - December 2022). This study included 37 patients treated for bile duct injuries and choledochal cysts. All patients had an ASA III or above, aged 5 to 36 years. Amongst the 35 patients, 21 patients underwent surgery for choledochal cysts, while 14 patients were treated for bile duct injuries. Patients with type 1choledochal cysts were admitted through OPD after getting diagnosed by ultrasound abdomen and, in some cases, MRCP.
RESULTSOut of 36 patients, 23 (63.71%) presented with type I choledochal cysts, while 14 (40%) exhibited bile duct injuries (BDI). Among the 14 BDI cases, 57.14% underwent open cholecystectomy, 42.85% underwent laparoscopic cholecystectomy, and 5.71% received immediate repair during the primary surgery. Conversely, 8.57% of patients with CBD ligation underwent exploration on the 3rd postoperative day upon early detection of the injury. Among the patients diagnosed with BDI after the 7th postoperative day, 25.71% underwent delayed repair at three months. Postoperatively, patients were authorized for fluid consumption within 24-48 hours. Moreover, 4 (11.42%) patients developed a fever of approximately 100°F, managed with intravenous Paracetamol in 2 (5.71%) cases. Patients also presented with subsequent wound infections, which were treated on an outpatient basis through oral antibiotics and wound dressing.
CONCLUSION
The Retropyloric Roux-en-Y hepaticojejunostomy is a modified biliary reconstruction procedure with minimal morbidity and better outcomes than traditional methods. It reduces complications like delayed gastric emptying and acute cholangitis. We recommend its frequent use for biliary reconstruction when appropriate.

Published: November 2024

The increasing cyber threats in Indonesia require strengthening the country's defense strategy. This study focuses on the formation of the Indonesian National Army (TNI) Cyber Force as part of efforts to strengthen the country's cyber security in facing increasingly complex threats. The purpose of this study is to analyze the policy and strategy for the formation of the TNI Cyber Force and evaluate the synergy between institutions, especially with the National Cyber ​​and Crypto Agency (BSSN). This study uses a qualitative method with a secondary data analysis approach, including reports from Fortinet, AwanPintar.id, and national policy documents related to cybersecurity. The research findings show that the TNI Cyber Force has a crucial role in protecting Indonesia's critical infrastructure from the threat of botnets, ransomware, and other cyber-attacks. The synergy between the TNI and BSSN is key to building an effective cyber defense system. Although there has been an increase in cyber readiness, this study found that challenges still exist, including in terms of human resources and the technology used. In conclusion, the formation of the TNI Cyber Force is an important step in dealing with cyber threats, but there needs to be further strengthening in cross-sector coordination and adoption of the latest technology.

Authors: Silva Fernanda Costa da , Rodrigues Junior Omero Martins
Published: November 2024

Introdução: A Síndrome de Abstinência Neonatal (SAN) é uma condição que afeta recém-nascidos expostos a opioides durante a gestação, manifestando-se por uma série de sintomas que impactam a saúde dos bebês. O tratamento mais comum envolve o uso de metadona e morfina, porém, ainda há discussões sobre quais desses medicamentos são mais eficazes no manejo da SAN. Desenvolvimento: O estudo visa comparar a eficácia da morfina e da metadona no tratamento da SAN em recém-nascidos de mães usuárias de opioides durante a gravidez. Estudos prévios apresentam variações na resposta clínica entre os fármacos, gerando interesse em uma análise mais aprofundada. Metodologia: Foi realizada uma revisão da literatura, analisando 10 artigos relevantes que abordaram a eficácia da metadona e da morfina. Os dados foram extraídos e organizados em uma tabela, focando em parâmetros como duração da internação (LOS), duração do tratamento (LOT) e outros resultados clínicos. Conclusão: Os resultados indicam que a metadona é mais eficaz que a morfina no tratamento da SAN, com uma menor duração de internação hospitalar e menor necessidade de adjuvantes. A metadona apresenta um perfil terapêutico mais eficiente e seguro, embora a morfina permaneça uma alternativa válida em alguns contextos específicos.
A Study on the Role of Women in Garo Tribal Society
Authors: Thakuria Sumi
Published: November 2024

Women are the main ornaments of a society. The place of men in society is the same place as that of a woman. In a society where there is equal rights between women and men, we can call it a healthy society. Women provide the fulfillment for the creation of a society. Therefore, the tribal people have always given high status to women. The Garos are one of the various tribes living in North East India where the role of women is advanced in all aspects. Therefore, the Garos are called the matriarchal tribe. The Garo women play a special role in managing everything from raising the family to managing everything. Our research will try to discuss the role of women in the life of the garo society.

We confirm the previous detection of 13CO in YSES 1 b at a higher significance of 12.6σ, but point to a higher 12CO/13CO ratio of 88 ± 13 (1σ confidence interval), consistent with the primary’s isotope ratio 66 ± 5. We retrieve a solar-like composition in YSES 1 b with a C/O = 0.57 ± 0.01, indicating a formation via gravitational instability or core accretion beyond the CO iceline. Additionally, the observations lead to detections of H2O and CO in the outer planet YSES 1 c at 7.3σ and 5.7σ, respectively. We constrain the atmospheric C/O ratio of YSES 1 c to be either solar or subsolar (C/O = 0.36 ± 0.15), indicating the accretion of oxygen-rich solids. The two companions have distinct

YSES 1 represents an intriguing system for comparative studies of super-Jovian companions and linking present atmospheres to formation histories.

Published: November 2024

Narrow emission lines in a galaxy’s spectrum that show double peaks indicate the presence of distinct gas components with different velocities, and its physical origin remains uncertain. This study uses galaxies from the final MaNGA data release to detect double-peaked narrow emission-line spaxels (DPSs) by examining the double Gaussian profiles of the Hα-[N ii] doublets across all MaNGA spaxels. A total of 5420 DPSs associated with 304 double-peaked narrow emission-line galaxies (DPGs) are identified, with each DPG containing a minimum of five DPSs and being free from overlap with other galaxies. We find that DPSs can be categorized into three groups according to their central distance r/R

e
and the velocity difference Δv between their two components: the inner low-Δv, inner high-Δv, and outer DPSs. By incorporating the physical characteristics of the DPGs into their DPSs, we demonstrate for the first time the existence of statistical correlations between barred DPGs and inner low-Δv DPSs, AGN-hosting DPGs, and inner high-Δv DPSs, as well as tidal DPGs and outer DPSs.

We investigate the connection between galaxies, dark matter halos, and their large-scale environments at z = 0 with Illustris TNG300 hydrodynamic simulation data. We predict stellar masses from subhalo properties to test two types of machine learning (ML) models: explainable boosting machines (EBMs) with simple galaxy environment features and

-invariant graph neural networks (GNNs). The best-performing EBM models leverage spherically averaged overdensity features on 3 Mpc scales. Interpretations via SHapley Additive exPlanations also suggest that in the context of the TNG300 galaxy–halo connection, simple spherical overdensity on ∼3 Mpc scales is more important than cosmic web distance features measured using the DisPerSE algorithm. Meanwhile, a GNN with connectivity defined by a fixed linking length, L, outperforms the EBM models by a significant margin. As we increase the linking length scale, GNNs learn important environmental contributions up to the largest scales we probe (L = 10 Mpc). We conclude that 3 Mpc distance scales are most critical for describing the TNG galaxy–halo connection using the spherical overdensity parameterization, but that information on larger scales, which is not captured by simple environmental parameters or cosmic web features, can further augment these models. Our study highlights the benefits of using interpretable ML algorithms to explain models of astrophysical phenomena, and the power of using GNNs to flexibly learn complex relationships directly from data while imposing constraints from physical symmetries.
Reconstruction of the Total Solar Irradiance During the Last Millennium

Published: November 2024

Solar irradiance variations across various timescales, from minutes to centuries, represent a potential natural driver of past regional and global climate cold phases. To accurately assess the Sun’s effect on climate, particularly during periods of exceptionally low solar activity, known as grand minima, an accurate reconstruction of solar forcing is essential. While direct measurements of the total solar irradiance (TSI) only began in the late 1970s, with the advent of space radiometers, indirect evidence from various historical proxies suggests that the Sun’s magnetic activity has undergone possible significant fluctuations over much longer timescales. Employing diverse and independent methods for TSI reconstruction is essential to gaining a comprehensive understanding of this issue. This study employs a semi-empirical model to reconstruct TSI over the past millennium. Our approach uses an estimated open solar magnetic field (F

o
), derived from cosmogenic isotope data, as a proxy for solar activity. We reconstruct the cyclic variations of TSI, due to the solar surface magnetic features, by correlating F

o
with the parameter of active region functional form. We obtain the long-term TSI trend by applying the empirical mode decomposition algorithm to the reconstructed F

o
to filter out the 11 yr and 22 yr solar variability. We prepare a reconstructed TSI record, spanning 971 to 2020 CE. The estimated departure from modern TSI values occurred during the Spörer minimum (around 1400 CE), with a decrease of approximately 2.3 Wm−2. A slightly smaller decline of 2.2 Wm−2 is reported during the Maunder minimum, between 1645 and 1715 CE.

We present the tidal disruption event (TDE) AT2022lri, hosted in a nearby (≈144 Mpc) quiescent galaxy with a low-mass massive black hole (104
M
⊙ < M
BH < 106
M
⊙). AT2022lri belongs to the TDE-H+He subtype. More than 1 Ms of X-ray data were collected with NICER, Swift, and XMM-Newton from 187 to 672 days after peak. The X-ray luminosity gradually declined from 1.5 × 1044 erg s−1 to 1.5 × 1043 erg s−1 and remains much above the UV and optical luminosity, consistent with a super-Eddington accretion flow viewed face-on. Sporadic strong X-ray dips atop a long-term decline are observed, with a variability timescale of ≈0.5 hr–1 days and amplitude of ≈2–8. When fitted with simple continuum models, the X-ray spectrum is dominated by a thermal disk component with inner temperature going from ∼146 to ∼86 eV. However, there are residual features that peak around 1 keV, which, in some cases, cannot be reproduced by a single broad emission line. We analyzed a subset of time-resolved spectra with two physically motivated models describing a scenario either where ionized absorbers contribute extra absorption and emission lines or where disk reflection plays an important role. Both models provide good and statistically comparable fits, show that the X-ray dips are correlated with drops in the inner disk temperature, and require the existence of subrelativistic (0.1–0.3c) ionized outflows. We propose that the disk temperature fluctuation stems from episodic drops of the mass accretion rate triggered by magnetic instabilities or/and wobbling of the inner accretion disk along the black hole’s spin axis.

The James Webb Space Telescope opens a new window to directly probe luminous quasars powered by billion solar mass black holes in the Epoch of Reionization and their coevolution with massive galaxies with unprecedented details. In this paper, we report the first results from a deep NIRSpec integral field unit spectroscopic study of a quasar at z = 7.5. We obtain a bolometric luminosity of ∼1.8 × 1047 erg s−1 and a black hole mass of ∼0.7–2.5 × 109
M
⊙ based on the Hβ emission line in the quasar spectrum. We discover ∼2 kpc scale, highly blueshifted (∼−870 km s−1) and broad (∼1400 km s−1) [O iii] line emission after the quasar point-spread function has been subtracted. Such line emission most likely originates from a fast, quasar-driven outflow, the earliest one at galactic scales known so far. The dynamical properties of this outflow fall within the typical ranges of quasar-driven outflows at lower redshift, and the outflow may be fast enough to reach the circumgalactic medium. Combining both the extended and nuclear outflow together, the mass outflow rate, ∼300 M
⊙ yr−1, is ∼60%–380% of the star formation rate of the quasar host galaxy, suggesting that the outflow may expel a significant amount of gas from the inner region of the galaxy. The kinetic energy outflow rate, ∼3.6 × 1044 erg s−1, is ∼0.2% of the quasar bolometric luminosity, which is comparable to the minimum value required for negative feedback based on simulation predictions. The dynamical timescale of the extended outflow is ∼1.7 Myr, consistent with the typical quasar lifetime in this era.
Comparative Planetology of Magnetic Effects in Ultrahot Jupiters: Trends in High-resolution Spectroscopy
Authors: Beltz Hayley , Rauscher Emily
Published: November 2024

Ultrahot Jupiters (UHJs), being the hottest class of exoplanets known, provide a unique laboratory for testing atmospheric interactions with internal planetary magnetic fields at a large range of temperatures. Thermal ionization of atmospheric species on the dayside of these planets results in charged particles becoming embedded in the planet’s mostly neutral wind. The charges will resist flow across magnetic field lines as they are dragged around the planet and ultimately alter the circulation pattern of the atmosphere. We model this process to study this effect on high-resolution emission and transmission spectra in order to identify observational signatures of the magnetic circulation regime that exist across multiple UHJs. Using a state-of-the-art kinematic MHD/active drag approach in a 3D atmospheric model, we simulate three different UHJs with and without magnetic effects. We postprocess these models to generate high-resolution emission and transmission spectra and explore trends in the net Doppler shift as a function of phase. In emission spectra, we find that the net Doppler shift before and after secondary eclipse can be influenced by the presence of magnetic drag and the wavelength choice. Trends in transmission spectra show our active drag models consistently produce a unique shape in their Doppler shift trends that differs from the models without active drag. This work is a critical theoretical step to understanding how magnetic fields shape the atmospheres of UHJs and provides some of the first predictions in high-resolution spectroscopy for observing these effects.

Intermediate-mass black hole (IMBH) mergers with masses 104–106
M
⊙ are expected to produce gravitational waves detectable by the Laser Interferometer Space Antenna (LISA) with high signal-to-noise ratios from the present day to cosmic dawn. IMBH mergers are expected to take place within dwarf galaxies; however, the dynamics, timescales, and effect on their hosts are largely unexplored. In a previous study, we examined how IMBHs would pair and merge within nucleated dwarf galaxies. IMBHs in nucleated hosts evolve very efficiently, forming a binary system and coalescing within a few hundred million years. Although the fraction of dwarf galaxies (107
M
⊙ ≤ M
⋆ ≤ 1010
M
⊙) hosting nuclear star clusters is between 60% and 100%, this fraction drops to 20%–70% for lower-mass dwarfs (M
⋆ ≈ 107
M
⊙), with the largest drop in low-density environments. Here, we extend our previous study by performing direct N-body simulations to explore the dynamics and evolution of IMBHs within nonnucleated dwarf galaxies, under the assumption that IMBHs exist within these dwarfs. To our surprise, none of the IMBHs in our simulation suite merge within a Hubble time, despite many attaining high eccentricities e ∼ 0.7–0.95. We conclude that extremely low stellar density environments in the centers of nonnucleated dwarfs do not provide an ample supply of stars to interact with an IMBH binary, resulting in its stalling, in spite of triaxiality and high eccentricity, common means to drive a binary to coalescence. Our findings underline the importance of considering all detailed host properties to predict IMBH merger rates for LISA.
Constraints on Acoustic Wave Energy Fluxes and Radiative Losses in the Solar Chromosphere from Non-LTE Inversions

Accurately assessing the balance between acoustic wave energy fluxes and radiative losses is critical for understanding how the solar chromosphere is thermally regulated. We investigate the energy balance in the chromosphere by comparing deposited acoustic flux and radiative losses under quiet and active solar conditions using non–local thermodynamic equilibrium inversions with the Stockholm Inversion Code. To achieve this, we utilize spectroscopic observations from the Interferometric BIdimensional Spectrometer in the Na i 5896 Å and Ca ii 8542 Å lines and from the Interface Region Imaging Spectrograph in the Mg ii h and k lines to self-consistently derive spatially resolved velocity power spectra and cooling rates across different heights in the atmosphere. Additionally, we use snapshots of a three-dimensional radiative magnetohydrodynamics simulation to investigate the systematic effects of the inversion approach, particularly the effect of attenuation on the velocity power spectra and the determination of the cooling rates. The results indicate that inversions potentially underestimate acoustic fluxes at all chromospheric heights while slightly overestimating the radiative losses when fitting these spectral lines. However, even after accounting for these biases, the ratio of acoustic flux to radiative losses remains below unity in most observed regions, particularly in the higher layers of the chromosphere. We also observe a correlation between the magnetic field inclination in the photosphere and radiative losses in the low chromosphere in plage, which is evidence that the field topology plays a role in the chromospheric losses.
Accelerated Structure Formation: The Early Emergence of Massive Galaxies and Clusters of Galaxies

Published: November 2024

Galaxies in the early Universe appear to have grown too big too fast, assembling into massive, monolithic objects more rapidly than anticipated in the hierarchical Lambda cold dark matter (ΛCDM) structure formation paradigm. The available photometric data are consistent with there being a population of massive galaxies that form early (z ≳ 10) and quench rapidly over a short (≲1 Gyr) timescale, consistent with the traditional picture for the evolution of giant elliptical galaxies. Similarly, kinematic observations as a function of redshift show that massive spirals and their scaling relations were in place at early times. Explaining the early emergence of massive galaxies requires either an extremely efficient conversion of baryons into stars at z > 10 or a more rapid assembly of baryons than anticipated in ΛCDM. The latter possibility was explicitly predicted in advance by modified Newtonian dynamics (MOND). We discuss some further predictions of MOND, such as the early emergence of clusters of galaxies and early reionization.

We present the Multi-Object Spectroscopy of Transient (MOST) Hosts survey. The survey is planned to run throughout the 5 yr of operation of the Dark Energy Spectroscopic Instrument (DESI) and will generate a spectroscopic catalog of the hosts of most transients observed to date, in particular all the supernovae observed by most public, untargeted, wide-field, optical surveys (Palomar Transient Factory, PTF/intermediate PTF, Sloan Digital Sky Survey II, Zwicky Transient Facility, DECAT, DESIRT). Science cases for the MOST Hosts survey include Type Ia supernova cosmology, fundamental plane and peculiar velocity measurements, and the understanding of the correlations between transients and their host-galaxy properties. Here we present the first release of the MOST Hosts survey: 21,931 hosts of 20,235 transients. These numbers represent 36% of the final MOST Hosts sample, consisting of 60,212 potential host galaxies of 38,603 transients (a transient can be assigned multiple potential hosts). Of all the transients in the MOST Hosts list, only 26.7% have existing classifications, and so the survey will provide redshifts (and luminosities) for nearly 30,000 transients. A preliminary Hubble diagram and a transient luminosity–duration diagram are shown as examples of future potential uses of the MOST Hosts survey. The survey will also provide a training sample of spectroscopically observed transients for classifiers relying only on photometry, as we enter an era when most newly observed transients will lack spectroscopic classification. The MOST Hosts DESI survey data will be released on a rolling cadence and updated to match the DESI releases. Dates of future releases and updates are available through the https://mosthosts.desi.lbl.gov website.
A general subpopulation model for the Animal Landscape and Man Simulation System (ALMaSS)
Authors: Duan Xiaodong , Topping Christopher J.
Published: November 2024

ALMaSS (the Animal Landscape and Man Simulation System) is a well-established modelling system known for its detailed agent-based animal models. However, for certain species, such as aphids, extremely high population sizes and limited detailed individual behaviour information make agent-based approaches either computationally expensive or unfeasible. Additionally, when these species are modelled as a prey base for other species, such as aphids for ladybirds, an efficient and accurate modelling approach is required. To address these challenges, we introduce a subpopulation-based model framework that effectively handles high population densities, while reducing computational complexity. This framework divides the landscape into a non-overlapping grid and population dynamics are managed within each grid using a flexible stage-structured population model. Grids are interconnected through short- and long-distance dispersal mechanisms, allowing for realistic movement and interactions. Parallel programming is employed to enhance performance, enabling faster simulation runs. We demonstrate the application of this model framework with a hypothetical species (not a species in the real world) and showcase its use in modelling aphid populations. This foundational subpopulation model could be used to model species with large population sizes within the ALMaSS framework and can be integrated into other simulation systems.
