Flow-based Generative Emulation of Grids of Stellar Evolutionary Models
Authors: Hon Marc , Li Yaguang , Ong Joel
Published: September 2024

We present a flow-based generative approach to emulate grids of stellar evolutionary models. By interpreting the input parameters and output properties of these models as multidimensional probability distributions, we train conditional normalizing flows to learn and predict the complex relationships between grid inputs and outputs in the form of conditional joint distributions. Leveraging the expressive power and versatility of these flows, we showcase their ability to emulate a variety of evolutionary tracks and isochrones across a continuous range of input parameters. In addition, we describe a simple Bayesian approach for estimating stellar parameters using these flows and demonstrate its application to asteroseismic data sets of red giants observed by the Kepler mission. By applying this approach to red giants in open clusters NGC 6791 and NGC 6819, we illustrate how large age uncertainties can arise when fitting only to global asteroseismic and spectroscopic parameters without prior information on initial helium abundances and mixing length parameter values. We also conduct inference using the flow at a large scale by determining revised estimates of masses and radii for 15,388 field red giants. These estimates show improved agreement with results from existing grid-based modeling, reveal distinct population-level features in the red clump, and suggest that the masses of Kepler red giants previously determined using the corrected asteroseismic scaling relations have been overestimated by 5%–10%.

The dispersion measure of fast radio bursts (FRBs), arising from the interactions with free electrons along the propagation path, constitutes a unique probe of the cosmic baryon distribution. Their constraining power is further enhanced in combination with observations of the foreground large-scale structure and intervening galaxies. In this work, we present the first constraints on the partition of the cosmic baryons between the intergalactic medium (IGM) and circumgalactic medium (CGM), inferred from the FLIMFLAM spectroscopic survey. In its first data release, the FLIMFLAM survey targeted galaxies in the foreground of eight localized FRBs. Using Bayesian techniques, we reconstruct the underlying ∼Mpc-scale matter density field that is traced by the IGM gas. Simultaneously, deeper spectroscopy of intervening foreground galaxies (at impact parameters b
⊥ ≲ r
200) and the FRB host galaxies constrains the contribution from the CGM. Applying Bayesian parameter inference to our data and assuming a fiducial set of priors, we infer the IGM cosmic baryon fraction to be

Dissipation of AGN Jets in a Clumpy Interstellar Medium
Authors: Dutta Riju , Sharma Prateek , Sarkar Kartick C. , Stone James M.
Published: September 2024

Accreting supermassive black holes frequently power jets that interact with the interstellar medium (ISM)/circumgalactic medium, regulating star formation in the galaxy. Highly supersonic jets launched by active galactic nuclei (AGN) power a cocoon that confines them and shocks the ambient medium. We build on the models of narrow conical jets interacting with a smooth ambient medium, including the effect of dense clouds, which are an essential ingredient of a multiphase ISM. The key physical ingredient of this model is that the clouds along the supersonic jet beam strongly decelerate the jet head but the subsonic cocoon easily moves around the clouds without much resistance. We propose scalings for important physical quantities—cocoon pressure, head and cocoon speed, and jet radius. For the first time, we obtain the analytic condition on the ambient medium’s clumpiness for the jet to dissipate within the cocoon and verify it with numerical simulations of conical jets interacting with a uniform ISM with embedded spherical clouds. A jet is defined to be dissipated when the cocoon speed exceeds the speed of the jet head. We compare our models with more sophisticated numerical simulations and direct observations of jet–ISM interaction (e.g., quasar J1316+1753), and we discuss implications for the Fermi/eROSITA bubbles. Our work also motivates effective subgrid models for AGN jet feedback in a clumpy ISM unresolved by the present generation of cosmological galaxy formation simulations.
Spindown of Pulsars Interacting with Companion Winds: The Impact of Magnetospheric Compression
Authors: Zhong Yici , Spitkovsky Anatoly , Mahlmann Jens F. , Hakobyan Hayk
Published: September 2024

Pulsars in binary systems with strong companion winds can have the magnetopause separating their magnetosphere from the wind located well within their light cylinder. This bow-like enclosure effectively creates a waveguide that confines the pulsar’s electromagnetic fields and can significantly alter its spindown. In this paper, we study the spindown of compressed pulsar magnetospheres in such systems. We parameterize the confinement as the ratio between the equatorial position of the magnetopause (or standoff distance) R
m and the pulsar’s light cylinder R
LC. Using particle-in-cell simulations, we quantify the pulsar spindown for a range of compressions, R
m/R
LC = 1/3–1, and inclination angles, χ = 0°…90°, between magnetic and rotation axes. Our strongly confined models (R
m/R
LC = 1/3) show two distinct limits. For χ = 0°, the spindown of a compressed pulsar magnetosphere is enhanced by approximately a factor of three compared to an isolated pulsar due to the increased number of open magnetic field lines. Conversely, for χ = 90°, the compressed pulsar spins down at less than 40% of the rate of an isolated reference pulsar due to the mismatch between the pulsar wind stripe wavelength and the waveguide size. We apply our analysis to the 2.77 s oblique rotator (χ = 60°) in the double-pulsar system PSR J0737-3039. With the numerically derived spindown estimate, we constrain its surface magnetic field to B
* ≈ (7.3 ± 0.2) × 1011 G. We discuss the time modulation of its period derivative, the effects of compression on its braking index, and implications for the radio eclipse in PSR J0737-3039.
Tracing the History of Obscured Star Formation with the SIMBA Cosmological Galaxy Evolution Simulation
Authors: Zimmerman Dhruv T. , Narayanan Desika , Whitaker Katherine E. , Davé Romeel
Published: September 2024

We explore the cosmic evolution of the fraction of dust-obscured star formation predicted by the simba cosmological hydrodynamic simulations featuring an on-the-fly model for dust formation, evolution, and destruction. We find that up to z = 3, our results are broadly consistent with previous observational results of little to no evolution in obscured star formation. However, at z > 3 we find strong evolution at fixed galaxy stellar mass toward greater amounts of obscured star formation, in tension with high-redshift observations. We explain the trend of increasing obscuration at higher redshifts by evolving star-dust geometry, as the dust-to-stellar mass ratios remain relatively constant across cosmic time. We additionally see that at a fixed redshift, more massive galaxies have a higher fraction of their star formation obscured, which is explained by increased dust-to-stellar mass ratios at higher stellar masses. Finally, we estimate the contribution of dust-obscured star formation to the total star formation rate budget and find that the dust-obscured star formation history peaks around z ∼ 2−3, and becomes subdominant at z ≳ 5. The dominance of obscured star formation at redshifts z ≲ 4 is consistent with our results for the evolution of the obscured star formation fraction at fixed stellar mass to higher values at higher redshift because there exist fewer massive, heavily obscured galaxies at high redshift.
Constructing a Ciliate Slide Collection in Mexico: First Steps
Authors: Mayén-Estrada Rosaura , Durán-Ramírez Carlos
Published: September 2024

Ciliophora is extremely diverse and probably the most studied group of heterotrophic protists, with cilia and a nuclear dimorphism (Simpson 2017). Records published in the 1920s identify 1026 species of ciliate protists (Alveolata: Ciliophora) in Mexico (Mayén-Estrada et al. 2020). Up to now, there has been no formal deposit of microscope slides in any collection in the country. The Protozoology Laboratory (at the Department of Comparative Biology in the Faculty of Sciences of the National Autonomous University of Mexico (UNAM) houses ciliate-mounted slides that are the result of research projects and theses since the 1990s. We aim to check the condition and quality of the slides to formalize an institutional collection. To date, we have found slides documenting around 90 ciliate genera, including both free-living species and symbionts, collected in 13 states of the Mexican Republic (Fig. 1).

Slides contain representatives of the 11 classes proposed by Lynn (2008), with the genus Vorticella (Class Oligohymenophorea) distributed in 11 Mexican states, and the genus Bresslauides (Class Colpodea) only in one state. The slides were created with several stain and impregnation techniques (Figs 2, 3).

Our goal is to inform and share the challenges faced to maintain this collection and achieve its recognition, all while exploring the possibilities of sharing it with the scientific community as part of Mexican natural history and protistological biodiversity.

Four complete mitochondrial genomes of the subgenus Pterelachisus (Diptera, Tipulidae, Tipula) and implications for the higher phylogeny of the family Tipulidae
Authors: Gao Yuetian , Cai Wanxin , Li Yupeng , Li Yan , Yang Ding
Published: September 2024

The complete mitochondrial genomes of Tipula (Pterelachisus) cinereocincta mesacantha Alexander, 1934, T. (P.) legalis Alexander, 1933, T. (P.) varipennis Meigen, 1818, and T. (P.) yasumatsuana Alexander, 1954 are reported, three of them being sequenced for the first time. The mitochondrial genome lengths of the four species are 15,907 bp, 15,625 bp, 15,772 bp, and 15,735 bp, respectively. All genomes exhibit a high AT base composition, with A + T content of 76.7%, 75.0%, 77.8%, and 75.4%, respectively. The newly reported mitogenomes herein show a general similarity in overall structure, gene order, base composition, and nucleotide content to those of the previously studied species within the family Tipulidae. Phylogenetic analyses were conducted to investigate the relationships within Tipulidae, using both Maximum Likelihood and Bayesian Inference approaches. The results show that the four target species of the subgenus T. (Pterelachisus) basically form a monophyletic group within Tipulidae, clustering with species of the Tipula subgenera T. (Lunatipula), T. (Vestiplex), and T. (Formotipula); however, the genus Tipula is not monophyletic. Moreover, neither the tipulid subfamily Tipulinae nor the family Limoniidae is supported to be a monophyletic group. The monophyly of the family Tipulidae, and the sister relationship between Tipulidae and Cylindrotomidae are reconfirmed. These research findings could contribute to deep insights into the systematic and evolutionary patterns of crane flies.
Les politiques de développement de l’éolien en mer en crise

Published: September 2024

Après une période d’envol porté par des espoirs de baisses spectaculaires des coûts, aujourd’hui contrariés par la hausse des taux d’intérêt et l’inflation générale, l’éolien en mer traverse une période difficile. Après avoir repéré les origines du problème, cet article cherche à montrer que ces difficultés sont moins dues à son accès à la maturité qu’à l’échec de la politique de son développement, d’un volontarisme déconnecté des réalités industrielles et basé sur des mécanismes de marché inadaptés à une technologie aussi capitalistique et lourde à mettre en œuvre. En conclusion, il trace la voie de ce que pourrait être un développement raisonné et maîtrisé de l’éolien en mer en Europe.

Published: September 2024

Diana Natalicio (1939 – 2021) served as the 10th president of the University of Texas at El Paso (UTEP) from the year 1988 until 2019. Her astonishing 31-year tenure as the highest representative in the university remained as the sixth-longest ever for any university president in history at the time of her retirement. Indeed, she also held the longest term for a female president of any American university and, above all, the first Hispanic. During Dr Natalicio's time as UTEP president, not only the enrolment grew but also the university's annual budget increased exponentially, increasing the number of doctoral programmes. Her continued commitment to provide all residents of the region of the Paso del Norte access to exceptional higher education opportunities helped make UTEP a national achievement story to a greater extend. On the verge of the second anniversary of her passing away, the objective of this paper is to draw public attention not only to Dr Natalicio's outstanding role at the UTEP university but, above all, to her legacy and testimony.

Authors: Kumar Harish , Kumar Himansh
Published: September 2024

The current experimental study is centered on exploring the advantages of hybrid biofuel derived from used cooking oil (UCO), on the performance, combustion, and emission characteristics of a 4-stroke single-cylinder CI engine. The hybrid biofuel is based upon microemulsification of UCO, ethanol, and 2-butanol. The break thermal efficiency (BTE) of UCOHBF was almost comparable with used cooking oil-based biodiesel (B100) and B50 but slightly lower than B10 and B20 and petrodiesel. The brake specific fuel consumption (BSFC) of UCOHBF was lower than B100 and comparable with B50 but higher than B10, B20, and petrodiesel. The combustion characteristics, such as peak cylinder pressure (CP) and net heat release rate (NHRR), demonstrated favorable outcomes for UCOHBF compared to both B20 and petrodiesel. Emission characteristics such as CO, CO2, and NOx showed superior results w.r.to B10, B20, B50, B100, and petrodiesel. UCOHBF showed superior performance and combustion characteristics w.r.to B20, B50, and B100.
Artificial Intelligence in Teaching Mathematics to Technical University Students

Published: September 2024

In light of the active proliferation of AI and its integration into all areas of our lives, the academic year 2023–2024 posed the most pressing question to educational methodologists: “How can AI be utilized in the educational process?” There was no question of whether to use AI or not. Advanced students – future programmers – are already fully applying it for educational and other purposes. In this research, the authors will share their experience of applying AI in teaching probability theory and other mathematical disciplines in a technical university, generalize it, and provide recommendations. Probability theory was chosen not by chance: it was one of the subjects whose content was not formalized and was not amenable to “Internet solvers.” AI fills this gap; it seems only a matter of time before AI can solve any probability problem. In this case, what should we teach?

Published: September 2024

Achieving balanced progress requires addressing critical issues such as environmental sustainability, gender equality, and human development. Using a time series research design, this study analyzes data from 2000 to 2021. This study variables in this research include human development index (HDI), the women, business, and the law index (WBL), the consumption-based carbon intensity (CCI), and the gender development index (GDI). Regression analyses, including Sobel-Goodman tests, and mediation were used to assess the overall, direct, and indirect effects of HDI on CCI with and without control variables. The results show that WBL mediates the relationship between HDI and CCI when control variables are considered. CCI was significantly impacted by HDI. The direct effect of HDI on CCI was no longer significant after accounting for mediation, suggesting a trade-off between development and environmental impact. The results highlight the necessity of implementing policies that combine environmental sustainability with gender equality.

Authors: Iqbal Sajid , Bilal Ahmad Raza , Abass Qaisar , Khan Imran
Published: September 2024

COPE-28 calls for China to control fossil fuel expansion and limit coal subsidies to achieve fossil fuel energy systems transition to make oil supply chains sustainable. China has not detailed its program about this, which warrants more work in theory and practice. Therefore, this research inquires to determine and limit fossil fuel expansion and coal subsidies with green finance in China to ensure COPE-28 commitments in conventional energy systems. The authors develop two scenarios using Chinese provincial categorization based on high fossil fuel consumption and low fossil fuel consumption. High fossil fuel consumption provinces are named Scenario 1 and others as Scenario 2. The authors applied the quantile clustering technique for scenario analysis. The study results show that green finance limits fossil fuel expansion by 0.22% in high fossil-consuming provinces and 0.17% in low fossil-consuming provinces by developing sustainable supply chains.

The proliferation of e-business has revolutionized the global marketplace, offering unprecedented opportunities for innovation, efficiency, and reach. However, this digital transformation has also introduced a complex array of ethical and legal challenges. This abstract explores the primary ethical and legal issues faced by e-businesses, emphasizing their implications and the need for robust governance frameworks. E-businesses must navigate a landscape fraught with ethical dilemmas, including data privacy, consumer protection, and digital divide concerns. Data privacy is paramount, as businesses collect vast amounts of personal information, raising questions about consent, data security, and the potential for misuse. Consumer protection is another critical issue, with e-businesses often criticized for misleading advertisements, poor customer service, and lack of transparency. Additionally, the digital divide presents an ethical challenge, as unequal access to technology exacerbates existing social inequalities, potentially marginalizing disadvantaged groups. The legal environment for e-business is equally challenging, characterized by rapidly evolving regulations and international complexities. Key legal issues include intellectual property rights, cyber security, and jurisdictional disputes. Intellectual property law struggles to keep pace with the digital age, where the unauthorized sharing and piracy of digital content are rampant. Cyber security is a growing concern, with legal implications for breaches that compromise sensitive data. Jurisdictional issues arise from the global nature of e-business, complicating the enforcement of laws and regulations across different countries with varying legal standards. Addressing these ethical and legal issues requires a multi-faceted approach. E-businesses must adopt ethical practices that prioritize consumer rights and data protection while actively working to bridge the digital divide. Legally, businesses need to stay abreast of regulatory changes and implement comprehensive compliance strategies. Collaboration between governments, industry stakeholders, and consumers is essential to create a balanced and fair e-business environment. Through such efforts, the potential of e-business can be harnessed while mitigating the risks associated with its growth. This exploration underscores the importance of continuous vigilance and adaptation in the face of evolving ethical and legal landscapes in e-business, aiming to foster a sustainable and equitable digital economy.
Performance of Thermally Stable Diamond Composite as Rock Cutting Tips under Varied Depth of Cut
Authors: Sun Yong , Li Xing Sheng , Guo Hua
Published: September 2024

The properties and the performance of Thermally Stable Diamond Composite (TSDC) directly affect the applications of TSDC in engineering. The failure risk of the TSDC cutting tips during a cutting process is affected by many factors, including the Depth of Cut (DOC) of the pick with the TSDC tip. The DOC is an important indicator in mining and construction industries because it directly affects productivity and pick failures. In existing studies, DOC is usually treated as a deterministic variable. However, due to the drum vibration during a cutting process, the DOC during production often varies randomly around its nominal value. This study investigates the influence of the randomly varied DOC on the performance and failure characteristics of TSDC tipped rock cutting picks, in combination with random resultant angle. Monte Carlo simulation method is applied. It is found that the variation in DOC can have considerable influence on the failure characteristics of the TSDC cutting tips, although this influence is affected by the resultant angle and attack angle. This characteristic is important for optimising the design and application of the TSDC tipped picks.

Published: September 2024

The intensity of heating of the insulation material of loaded electric wires was investigated. Calculations were made for insulation materials made of polyvinyl chloride plastic and rubber, and copper and aluminum wires. The dependences of the heating temperature of the wires on the time of their operation at load currents smaller, close to and larger than the maximum allowable ones are plotted. The time during which you spend heated to critical temperatures, is individual for each brand-size. For wires with a copper core, heating occurs more slowly compared to wires with an aluminum core. Wires with polyvinyl chloride core insulation heat up more slowly than wires with rubber core insulation. In all cases, addiction temperature of the wires from the time of operation at different load currents has a logarithmic form.

Published: September 2024

The current research focus in our group is on utilizing the polymer material polyimide (PI) as the resistance switching layer for resistive memory. In recent years, PI resistive photomemory (RePM) [1] has been developed, capitalizing on the photosensitive properties of PI films in the ultraviolet light band. PI initially possesses two chemical structures, Aromatic and Quinoid, the PI film undergoes transformation when exposed to ultraviolet light. By employing various processing methods to control the ratio of Quinoid and Aromatic molecular chains in the PI film, and through FTIR measurements of chemical structure changes before and after illumination, we gain insights into the variations in the molecular chain ratio due to different experimental parameters. FTIR analysis reveals that changes in spin coating speed influence the molecular ratio within the film, attributed to differences in molecular chain shapes and lengths. Experimental results demonstrate that optimizing the spin coating process enhances the operational efficiency of RePM, significantly extending data retention time.

Published: September 2024

Learner-centered feedback is one of the most powerful influences in learning and achievement. However specific literature on feedback for culturally diverse environments, such as Sri Lanka is lacking. By addressing this problem, we aimed to enhance learning and teaching in medical schools by identify and explore a culturally sensitive feedback guidance for Medical Education.
This qualitative, ethnographic, case study of the ethnically diverse Eastern University, Sri Lanka (EUSL) was emergent in design. Staff and students of EUSL represent predominantly three different ethnicities, Sinhala, Tamil and Muslim.
Data gathering utilized observation of learning conversations with three types of stakeholders, students, faculty and policy makers. Planned thematic analysis was usefully supplemented by discourse analysis in order to reduce uncritical imposition of western concepts.
Findings identified under-problematization of feedback practices, unaddressed cultural and historical complexities and willingness to develop post-colonial challenges to overly simplistic hegemonic “west is best” assumptions. Non-WEIRD (Westernised, Educated, Industrialised, Rich and Democratic) countries e.g. Sri Lanka can be benefitted from WEIRD evidence-based theories such as dialogic feedback and learner transitions best when informed by and adapted to local cultural practices and knowledge.
