Uma nutrição adequada é um dos fatores mais importantes para animais de laboratório e, dessa forma, o consumo de ração ad libitum torna-se uma variável que pode impactar nos resultados das pesquisas. O objetivo do presente estudo foi investigar a influência da dieta ad libitum nos parâmetros murinométricos e bioquímicos de ratos Wistar. Foram utilizados 11 ratos Wistar (Rattus norvegicus), machos e fêmeas, com 90 dias de vida, alocados em gaiolas coletivas e alojados no Núcleo de Pesquisa Experimental (NUPE) do UNIFIP. Os animais foram acompanhados durante sete semanas e divididos em: Grupo Controle Macho (GCM) e Grupo Controle Fêmea (GCF): Ração padrão com quantidade controlada (30 g/dia por animal); Grupo Dieta Macho (GDM) e Grupo Dieta Fêmea (GDF): Ração padrão ofertada ad libitum. A análise do consumo médio da ração foi calculada semanalmente. Os parâmetros bioquímicos e as medidas murinométricas foram aferidas no final do experimento, após anestesia total nos animais. Os resultados foram analisados pela ANOVA, seguido do Teste de Tukey, com nível de significância de p <0,05. Quanto as medidas murinométricas, os animais do GDM apresentaram maior ganho de peso, maior IMC e maior circunferência abdominal, enquanto que os animais do GDF apresentaram maior IMC, comparados aos GCM e GCF, respectivamente. Quanto aos parâmetros bioquímicos, os animais do GDM apresentaram aumento nos níveis da glicemia de jejum, triglicerídeos e colesterol total comparado com os animais do GCM. Já os animais do GDF apresentaram aumento nos níveis de triglicerídeos e colesterol total comparado com o GCF O estudo forneceu evidências que o acesso livre à ração pode levar a um aumento do ganho de peso e a alterações metabólicas em ratos Wistar, com diferenças observadas entre os sexos. A análise conjunta dos dados do presente estudo, juntamente com evidências anteriores, fortalece a compreensão dos efeitos da dieta ad libitum no ganho de peso e na saúde metabólica, podendo orientar novas pesquisas.

Authors: Ajay Dinesh Sharma , Dogga Satyanarayanamurthy
Published: November 2024

Financial inclusion has been an essential area of focus of the modern-day government. Financial inclusion means providing financial services to each section of society that demands it at an affordable cost. Nowadays, along with the efforts made by traditional financial institutions, the amalgamation of digital technology with finance, called digital finance, has significantly improved the base and coverage of financial inclusion. In India, the coverage of financial services has expanded after the introduction of the JAM (Jan Dhan- Aadhar- Mobile) trinity and the Unified Payment Interface (UPI). The increased internet penetration in the country has also expanded the scope of digital financial services. During demonetisation and the Covid-19 pandemic, digital financial services became a saviour for people and got a boost in its growth in India. The focus of this paper is to measure the level of digital financial inclusion in India. We have constructed a Digital Financial Inclusion Index for India using Principal Component Analysis (PCA). We have included the ‘Access’ (covers the supply side) and ‘Usage’ (covers the demand side) dimensions for this. The data from RBI and the National Payments Corporation of India (NPCI) has been used for the study. The study stresses the increasing role of digital finance in financial inclusion in India. This will guide the policy formulators to take key steps to improve the financial inclusion levels to achieve the goal of sustainable economic growth.

In the refining and petrochemical industries, a large percentage of all plants are distillation units, which are key to achieving the required economic indicators. Control systems for multi-column distillation units must ensure optimal and reliable operation at a given product purity. The design of a good control system for such plants is very import-ant to ensure reliable and high-quality operation of the whole process and is a challenging task due to the uncertainties associated with the complex process dynamics and the different composition of the feed stream affecting the separation behavior of the mixture. The paper summarizes the control structures developed based on predictive models to control the quality of the products produced. It is proposed to control the level in the tank of the partial condenser distillation column by (i) the distillate flow rate; (ii) the reflux flow rate, allowing the distillate flow rate to be used as a manipulated variable. The suitability of using control systems is determined based on steady-state controllability analysis and by studying the closed-loop dynamic characteristics (setpoint responses).

AI vs. AI: The Digital Duel Reshaping Fraud Detection
Authors: Balamurugan Merlin
Published: November 2024

In the evolving landscape of financial security, a new battlefront has emerged: synthetic identity fraud powered by Generative Artificial Intelligence (GAI). This paper examines the high-stakes digital duel between fraudsters wielding GAI and the adaptive defense mechanisms of financial institutions. The paper explores how GAI-created synthetic identities challenge traditional fraud detection paradigms with convincing backstories, digital footprints, and AI-generated images. These artificial personas’ unprecedented scale and sophistication threaten to overwhelm existing security infrastructures, potentially compromising the integrity of financial systems and identity verification frameworks. Our analysis reveals large-scale synthetic identity campaigns’ far-reaching economic implications and disruptive potential across multiple sectors. It also investigates cutting-edge countermeasures, including adversarial machine learning, real-time anomaly detection, and multi-modal data analysis techniques. As this technological arms race intensifies, the paper concludes by proposing future research directions and emphasizing the critical need for collaborative initiatives to stay ahead in this ever-evolving digital battlefield.

Authors: Bajaj Muskaan , Lama Swikar
Published: November 2024

This research uses comparative analysis of the use of geographical profiling approaches in the investigation of serial crimes on a global scale and in India. Geographical profiling is an essential tool in serial crime investigations since it helps to unearth criminal patterns and predict future crime locations based on the spatial behaviour of individual perpetrators. The research will offer an evaluation of the techniques utilized in different regions, highlighting the specific hurdles and achievements in their implication in the global context as opposed to the Indian context. This study uses various research studies delving into the Indian approaches and the international scenarios specifying the major differences amongst the policing strategies aided with or without geographical profiling. The objective of this study is for these findings to result in more streamlined investigative procedures and improved allocation of resources in instances of serial crimes.
Centenary Paper: Christianization of Nahua Religion: Presenting Tezcatlipoca as the Invisible Supreme God in the Works of Bernardino de Sahagún
Authors: LEE JONGSOO
Published: November 2024

In his major works, such as the
Florentine Codex
and the
Historia general de las cosas de Nueva España
, Bernardino de Sahagún described the Aztec god, Tezcatlipoca, as the only invisible and impalpable supreme deity. This portrayal aimed to present Tezcatlipoca as a god with Christian-like attributes, but far different from other Indigenous deities. This essay, however, extensively challenges such a presentation of Tezcatlipoca by thoroughly examining the divine traits and roles of Tezcatlipoca in Prehispanic historical and religious traditions. Before the Conquest, Huitzilopochtli, not Tezcatlipoca, held the position of the supreme deity as it was the patron god of the Mexicas, the people of Tenochtitlan, who politically and militarily dominated the Prehispanic world. Additionally, characterizing Tezcatlipoca as an invisible and impalpable god contradicts Prehispanic religious practices as Indigenous people were actively engaged in visualizing their gods through the ixiptlahuan (impersonators) and communicated with them through the tlaquimilolli (sacred bundles or gods’ relics). This essay argues that Sahagún assimilated the Indigenous Tezcatlipoca to the Christian god as a strategic move to facilitate his evangelical project.
Theory of Turbulent Equilibrium Spheres with Power-law Linewidth–Size Relation
Authors: Moon Sanghyuk , Ostriker Eve C.
Published: November 2024

Dense cores inherit turbulent motions from the interstellar medium in which they form. As a tool for comparison to both simulations and observations, it is valuable to construct theoretical core models that can relate their internal density and velocity structure while predicting their stability to gravitational collapse. To this end, we solve the angle-averaged equations of hydrodynamics under two assumptions: (1) the system is in a quasi-steady equilibrium; (2) the velocity field consists of radial bulk motion plus isotropic turbulence, with turbulent dispersion increasing as a power law in the radius. The resulting turbulent equilibrium sphere (TES) solutions form a two-parameter family, characterized by the sonic radius r

s
and the power-law index p. The TES is equivalent to a Bonnor–Ebert (BE) sphere when r

s
→ ∞ . The density profile in the outer regions of the TES is slightly shallower than the BE sphere, but is steeper than the logotropic model. Stability analysis shows that the TESs with size exceeding a certain critical radius are unstable to radial perturbations. The center-to-edge density contrast, mass, and radius of the marginally stable TES all increase with increasing average velocity dispersion. The FWHM of the column density profile is always smaller than the critical radius, by a larger factor at higher velocity dispersion, suggesting that observations need to probe beyond the FWHM to capture the full extent of turbulent cores. When applied to the highly turbulent regime typical of cluster-forming clumps, the critical mass and radius of the TES intriguingly resembles the typical mass and radius of observed star clusters.

We study the spectropolarimetric properties of a newly discovered black hole (BH) X-ray binary Swift J151857.0-572147 jointly using Imaging X-ray Polarimetry Explorer (IXPE) and NuSTAR observations during 2024 March. The analysis of IXPE data reports the first detection of X-ray with a polarization degree (PD) of 1.34 ± 0.27 and a polarization angle (PA) of −13.°69 ± 5.°85 using a model-independent approach, while the model-dependent analysis gives a PD of 1.18 ± 0.23 and a PA of −14.°01 ± 5.°80. The joint spectral analysis of the broadband data and NuSTAR analysis in isolation constrain the mass of the central BH between ∼9.2 ± 1.6 and 10.1 ± 1.7M
⊙ and a moderate spin parameter of ∼0.6 ± 0.1–0.7 ± 0.2 with a disk inclination of ∼35° ± 7°–46° ± 15°. The power-law photon index and cutoff energy are 2.19 ± 0.03–2.47 ± 0.06 and ∼36 ± 4–78 ± 10 keV, suggesting a transition to the soft spectral state. Additionally, a relatively lower corona size of 6 ± 1–9 ± 2r

), and the best-fitted halo accretion is less compared to the disk accretion rate further confirm the same state. The low PD detected in the soft state can be due to repeated scattering inside the dense corona, and the dominant emission from the disk agrees with the low spin and low disk inclination. The hydrogen column density obtained from the fit is relatively high at ∼4–5 × 1022 cm−2.

. We addressed discrepancies in the size evolution rates of SFGs, which may be caused by variations in sample selection and methods for size measurements. To check these factors, we traced the evolution of individual galaxies by identifying their progenitors using stellar mass growth histories (SMGHs), integrating along the star-forming main sequence and from the IllustrisTNG simulations. Comparison between the structural parameters estimated from the mass- and light-based profiles shows that mass-weighted size evolves at a slower pace compared to light-based ones, highlighting the need to consider the mass-to-light ratio (M/L) gradients. Additionally, we observed mass-dependent growth in stellar mass profiles: massive galaxies (

) formed central regions at z ≳ 1.5 and grew faster in outer regions, suggesting inside-out growth, while intermediate-mass and less massive SFGs followed a relatively self-similar mass buildup since z ∼ 2. Moreover, slopes of observed size evolution conflict with the predictions of TNG50 for samples selected using the same SMGHs across our redshift range. To explore the origin of this deviation, we examined changes in angular momentum (AM) retention fraction using the half-mass size evolution and employing a simple disk formation model. Assuming similar dark matter halo parameters, our calculations indicate that the AM inferred from observations halved in the past 10 Gyr while it remained relatively constant in TNG50. This higher AM in simulations may be due to the accretion of high-AM gases into disks.
CZ Aqr: An Oscillating Eclipsing Algol-type System Composed of a δ Sct Primary Star and a Subgiant Star in a Quadruple System

Eclipsing Algol-type systems containing a δ Scuti (hereafter δ Sct) star enable precise determination of physical parameters and the investigation of stellar internal structure and evolution. We present the absolute parameters of CZ Aquarius (hereafter CZ Aqr) based on TESS data. CZ Aqr has an orbital period of 0.86275209 day, a mass ratio of 0.489 (6), and the secondary component nearly fills its Roche lobe. O − C analysis reveals a downward parabolic trend and a cyclical variation with a period of 88.2 yr. The downward parabola suggests a long-term decrease in the orbital period with

⊙. Additionally, there are two possible celestial bodies in a 2:7 resonance orbit around CZ Aqr. The asymmetric light curve is explained by adding a hot spot on the surface of the primary star. After removing the binary model, 26 frequencies were extracted from TESS data. Two radial modes were newly identified among three possible independent frequencies. Our results show that the eclipsing Algol-type system is composed of a δ Sct primary star and a subgiant star in a quadruple system.

Gamma-ray emission is observed coincident in position to the evolved, composite supernova remnant (SNR) B0453–685. Prior multiwavelength investigations of the region indicate that the pulsar wind nebula (PWN) within the SNR is the most likely origin for the observed gamma rays, with a possible pulsar contribution that becomes significant at energies below E ∼ 5 GeV. Constraints on the PWN hard X-ray spectrum are important for the most accurate broadband representation of PWN emission and determining the presence of a gamma-ray pulsar component. The results of Parkes radio and Nuclear Spectroscopic Telescope Array (NuSTAR) X-ray observations are presented on PWN B0453–685. We perform a search for the central pulsar in the new Parkes radio data, finding an upper limit of 12 μJy. A pulsation search in the new NuSTAR observations additionally provides a 3σ upper limit on the hard X-ray pulsed fraction of 56%. The PWN is best characterized with a photon index ΓX = 1.91 ± 0.20 in the 3–78 keV NuSTAR data, and the results are incorporated into existing broadband models. Last, we characterize a serendipitous source detected by Chandra and NuSTAR that is considered a new high-mass X-ray binary candidate.

The optical flow algorithm (OF) is one the main methods for calculating image velocity field and has many applications in space weather. Most OF calculations are applied to the motion of labeled rigid objects and are not suitable for velocity detection of high-energy particles, such as in a coronal mass ejection (CME). Fluctuations in exposure time and the influence of space weather will lead to inconsistent brightness of the same feature point at different times. To address this problem, we propose an unsupervised multiscale optical flow network based on Vision Transformer, named UTFlowNet. The network comprises a multiscale feature extraction module and a coarse-to-fine global optical flow calculation module. The movement of high-energy particles emitted during a CME eruption follows certain physical rules. Therefore, we apply fluid motion–based loss functions to analyze the motion of high-energy particles more effectively, addressing the problem of CME motion field extraction. Our method can be applied to the real-time automatic extraction of a CME’s velocity field and performs well with inconsistent brightness, large-scale motion, and strong CME noise. Additionally, we can estimate subpixel level fine-grained velocity. Our model may be affected by overfitting during cross–data set inference, so we encourage performing a small amount of transfer learning on new data sets to mitigate this issue. In order to verify the accuracy of our method, we conducted experiments and verification on the Solar and Heliospheric Observatory LASCO C2 data and the High Altitude Observatory MLSO data. We constructed a large-scale displacement simulation data set based on LASCO C2 data and tested on it, achieving the best results.
Species descriptions in myxomycetes – can we settle on rules for good taxonomic practice?

Published: November 2024

Myxomycetes are an unique branch of life, recognizable by sporophores showing a fungus-like dispersal biology. These structures bear nearly all diagnostic characters for species identification and develop by rapid transformation of plasmodia. During this short period of time, external factors can significantly influence the formation of morphological characters. Therefore, the description of a new species must be carried out with utmost care. Over the last 50 years, approximately 10–15 new species of myxomycetes have been described per year, and only some of the latest publications underpin this with molecular data. In this paper, we discuss a set of recommendations for the description of myxomycete species new to science, striving for the following goals: (i) to minimize the number of erroneous descriptions of the species, whose names later have to be put into synonymy; (ii) to make all respective data easily accessible for the scientific community; and (iii) to comply with existing rules of nomenclature. We recommend (1) whenever possible not to describe a new taxon from a single gathering, however an exception could be made if supported by molecular data and by unique morphological characters which are unlikely to fall in the range of infraspecific variation of related species; (2) preparing detailed descriptions, including data on developmental stages, microhabitats, ecology, phenology and associated species; (3) providing at least two independent diagnostic characters that tell the new species apart from all others; (4) obtaining a molecular barcode and, whenever possible, providing proof for reproductive isolation of the new species from related taxa; and (5) depositing type specimens in public herbaria. To comply with nomenclatural rules, (6) the new name must be registered in a recognized repository, (7) all published names should be checked for usability before proposing a new name, and (8) a novel and unique name should be chosen, preferably highlighting a distinct character of the new species.

In recent years, society become much more interested in nature disasters that cause damage. The consequences of these destructive processes of a meteorological, hydrological and geological nature sometimes remain for years until the affected areas are recultivated, restored and recovered. These natural processes work together, often following each other or triggering each other to create a massive system of destruction that causes a lot of damage and often leads to death and numerous casualties.

Moreover, with the changes in the global climate of the Planet, leading to the more frequent manifestation of more destructive natural phenomena - cyclones, storms, huge amounts of precipitation - lead to intensify and manifest in larger scales and volumes geological phenomena such as landslides, mudflows, mud - stone torrents, rockfalls, collapses of different character of slopes, linear and planar erosion etc.

This is extremely relevant for Bulgaria, the territory for which is no exception to the manifestation of catastrophic natural phenomena. The country is located in an active orogenic zone as part of the Alpo-Himalayan tectonic belt, characterised by a complex tectonic structure, variable and diverse geological formations and rapid topographical changes.

The main focus in the study is to present an advanced, multi-faceted framework for natural disaster risk assessment, integrating biodiversity and archaeological sites. Moreover, the assessments of natural risks made so far do not include sufficient attention to biotopes and archaeological and historical sites.

The presented methodology is applied to landslide hazards in a pre-selected area along the northern Bulgarian Black Sea coast. The main goal of this paper is to identify socio-environmental risks in the studied region, as well as to construct risk profiles and visually represent both qualitative and quantitative risk levels in the socio-ecological system and biodiversity.

Published: November 2024

Eponyms are widely used in the field of orthopedic surgery, including for surgical instruments. Although their use is at times controversial, an appreciation of the history behind eponymous terms allows one to both recognize the shortcomings of the past and simultaneously be inspired by ingenious inventors. The primary purpose of this review is to provide a historical perspective of clamps and forceps commonly used in orthopedic surgery, to better appreciate the evolution of their use over time, and to inspire innovation to constantly improve upon surgical instrumentation as the field of orthopedic surgery advances.

Published: November 2024

Background

The relative contributions of common patient-reported social determinants of health on 30- and 90-day post-discharge outcomes among patients with acute coronary syndromes (ACS) is unclear.

Objective

The aim of this article is to examine the independent associations of social determinants with readmission or death, accounting for medical history.

Methods

Participants included adults who were hospitalized with ACS at an academic medical center. Domains measured were social support, health literacy/numeracy, and socioeconomic status (SES) (including education and difficulty paying bills). We employed multivariable Cox proportional hazard models to study associations with time to all-cause readmission or death, up to 30 or 90 days after discharge, and adjusted for demographics and medical history (prior admissions and Elixhauser comorbidity index).

Key Results

Among 1,168 patients with ACS and no history of heart failure, more prior admissions, and higher comorbidity index (the medical history domain) were associated with higher rates of 30- and 90-day readmission or death (domain
p
values <.01 and <.0001, respectively). The social support domain was not associated with outcomes. Higher health literacy and numeracy were associated with lower rates of 30- and 90-day readmission or death (domain
p
values .016 and .002, respectively). Higher education and less difficulty paying bills (the SES domain) was marginally associated with lower rates of 90-day readmission or death (domain,
p
= .052).

Conclusions

In addition to medical history, the domain of health literacy and numeracy was independently associated with readmission or death of patients with ACS during the 90 days after hospital discharge. [

Un tribunal des idées pour discuter de transition après la fermeture d’une centrale nucléaire
Authors: Erné-Heintz Valentine
Published: November 2024

Le nucléaire se trouve aux interactions entre sciences et société du fait de l’ampleur des défis économiques, politiques, sociaux, environnementaux et éthiques que cette technologie porte en elle. En effet, les questionnements qu’il suscite vont bien au-delà des questionnements scientifiques et de la communauté des experts que les débats récents autour de la taxonomie européenne ont ravivé. Le nucléaire génère des controverses passionnelles, des oppositions et des conflits dans la société. Dans ce contexte, la question porte sur la capacité à faire participer de jeunes citoyens dans le débat sur le devenir d’un territoire après la fermeture d’une centrale. L’hypothèse sous-jacente porte sur l’intérêt d’introduire un serious game dans un contexte controversé et sa capacité à faire émerger un consensus autour d’une nouvelle trajectoire. Ainsi, après avoir présenté le cadre de notre étude de cas, nous exposerons les résultats afin de comprendre comment de jeunes collégiens du territoire s’emparent du devenir de leur territoire, celui d’un territoire nucléarisé controversé.
Enseigner les œuvres chorégraphiques. Statuts et missions des répétiteur·ices dans les compagnies classiques
Authors: Cappelle Laura
Published: November 2024

En plus des professeur·es de danse, une autre figure tient un rôle pédagogique essentiel dans le champ chorégraphique. Les répétiteur·ices réalisent au quotidien un travail de transmission qui en fait des « passeur·ses » centraux dans les processus de répétition. À partir d’entretiens et d’observations menés auprès de plusieurs compagnies classiques internationales, les statuts variables des répétiteur·ices dans les compagnies classiques de répertoire – permanent·es, invité·es – sont présentés, ainsi que la transition progressive du métier d’interprète vers celui de répétiteur·ice qui constitue un mode privilégié d’entrée dans la carrière. Les responsabilités concrètes des répétiteur·ices en studio sont ensuite détaillées, des tâches techniques aux fonctions artistiques. Est interrogée enfin la dimension créative du travail de ces pédagogues, souvent peu reconnue, à partir d’exemples soulignant les manières dont les répétiteur·ices peuvent informer les œuvres et participer activement à l’élaboration de la chorégraphie.

Les habiletés numériques et arithmétiques de base sont affectées chez les personnes avec déficience intellectuelle (DI). Des études récentes montrent que le recours aux doigts est une procédure qui peut faciliter la construction de ces habiletés chez les enfants au développement typique. Cette étude vise à caractériser le recours aux doigts chez les élèves avec DI lorsqu’ils ont à résoudre des petits problèmes verbaux ou avec énoncés arithmétiques. Il s’agit aussi d’étudier les relations entre certaines composantes de la motricité manuelle, le recours aux doigts et les premières habiletés numériques et de calcul. Les résultats indiquent que les élèves avec DI âgés en moyenne de 10 ans et 4 mois qui utilisent les doigts pour résoudre des problèmes arithmétiques ou avec énoncés verbaux sont plus fréquemment en réussite. Comme pour les enfants au développement typique, les différences de dextérité pourraient expliquer les différences interindividuelles de recours à cette procédure pour le calcul. Ces résultats permettent de considérer le potentiel bénéfice d’un dispositif d’enseignement explicite à l’usage des doigts en mathématiques pour des élèves présentant une déficience intellectuelle.
