Los zulos de la inclusión: reconocimiento, resentimiento y un paso atrás
Authors: Méndez Cota Gabriela
Published: July 2024

Este ensayo relaciona, por una parte, el pensamiento inclusivo con la cuestión moral del reconocimiento y, por otra, con el problema existencial del resentimiento y la técnica en la globalización híper-industrial. Se contrastan e integran perspectivas como las de Anne Phillips, Axel Honneth, María Pía Lara, Bernard Stiegler y Cynthia Fleury, para argumentar que los desarrollos tecnoeconómicos y sociales de la última década obligan a recuperar el problema del reconocimiento, para replantearlo por fuera de una racionalidad normativa, esto es, a la luz de sus dimensiones psíquicas y existenciales. Dado que las condiciones tecnoeconómicas actuales parecen eliminar la posibilidad de un reconocimiento genuino —o una igualdad sin condición—, el problema del pensamiento inclusivo se revela, en el fondo, como el del resentimiento ante el descrédito de las promesas morales y políticas de la modernidad. El ensayo termina con una reflexión sobre las implicaciones de este argumento para una consideración responsable del pensamiento inclusivo, en tanto fenómeno cultural situado. El libro Desde los zulos (2023), de la escritora feminista Dahlia de la Cerda, nos permite mostrar que no hay determinismo tecnoeconómico o metafísico total, sino agujereado, y que de los agujeros brota, a veces, algo así como el reconocimiento. Al mismo tiempo, deja abierta la cuestión de si eso que emerge le pertenece a un nuevo sujeto estético-político, o si sucede, sin más, como la diferencia absoluta entre vida y política.
PARTICIPAÇÃO DA AGRICULTURA FAMILIAR NO PROGRAMA NACIONAL DE ALIMENTAÇÃO ESCOLAR DA REDE MUNICIPAL DE VARGINHA-MG
Authors: Davanzo Bianca Beatriz , Moreira Vinícius de Souza
Published: July 2024

O Programa Nacional de Alimentação Escolar (PNAE) determina que 30% dos recursos federais repassados para a sua execução sejam destinados às compras da agricultura familiar. No entanto, por se tratar de uma política pública de abrangência nacional, executada de forma descentralizada, a observância desta cota mínima pelos municípios vem ocorrendo de maneira distinta, justificando estudos que se debruçam sobre uma realidade local. À vista disso, este artigo pretendeu avaliar a participação da agricultura familiar no PNAE da rede de ensino público municipal de Varginha–MG, nos anos de 2017 a 2022, a fim de verificar se o objetivo da política pública de incluir este segmento nas compras institucionais está sendo cumprido. Para isso, efetuou-se uma pesquisa quantitativa, cujos dados foram obtidos a partir de fontes primárias (Secretaria Municipal de Educação, Censo Escolar e reportagens). Para instrumentalizar a análise, foram formulados indicadores de avaliação: Participação da Agricultura Familiar (PAgF); Grau de Cobertura (GC) e Participação Municipal no PNAE (PMun); e para o tratamento dos dados, foram aplicados métodos de estatística descritiva. Os principais resultados demonstraram que a PAgF no PNAE executado na rede de ensino público municipal de Varginha–MG foi, em média, superior a 60% em todos os anos do período estudado, superando o mínimo legal de 30%. Concluiu-se, portanto, que a meta de inclusão dos agricultores foi atingida. Todavia, observou-se tendência de queda na PAgF no período analisado, cujas causas merecem ser investigadas em estudos futuros.

Modelling and Optimization of Residential Electricity Load under Stochastic Demand
Authors: Mubiru Kizito
Published: July 2024

The paper considers a modelling framework for a set of households in residential areas; using electricity as a form of energy for domestic consumption. Considering the demand and availability of units for electricity consumption, optimal decisions for electricity load allocation are paramount to sustain energy management. We formulate this problem as a stochastic decision-making process model where electricity demand is characterized by Markovian demand. The loading and operational framework is governed by the demand and supply phenomena; where shortage costs are realized when demand exceeds supply. Empirical data for electricity consumption was collected from fifty households in two residential areas within the suburbs of Kampala in Uganda. Data collection was made at hourly intervals over a period of four months. The major problem focussed on determining an optimal electricity loading decision in order to minimize consumption costs as demand changes from one state to another. Considering a multi-period planning horizon, an optimal decision was determined for loading or not loading additional electricity units using Markov decision process approach. The model was tested; whose results demonstrated the existence of an optimal state-dependent decision and consumption costs considering the case study used in this study. The proposed model can be cost-effective for managers in the electricity industry. Improved efficiency and utilization of resources for the distribution systems of electricity to residential areas was realised; with subsequent enhanced reliability of service to essential customers of the energy market.
Morphological and phenological variation of flower colour morphs in a wild population of Opuntia streptacantha (Cactaceae)
Authors: Manzanarez-Villasana Gerardo , Mandujano María C.
Published: July 2024

Background and aims – Opuntia s.s. (Cactaceae) is one of the most diverse genera in the subfamily Opuntioideae, with approximately 220 species. The considerable morphological and anatomical diversity among these species has resulted in a remarkable adaptative plasticity, evident in both intra- and interspecific variability. Our study system is Opuntia streptacantha, which has two flower colour morphs: yellow and orange. The objective is to determine if there are morphological differences in the reproductive and vegetative structures between floral morphs.

Material and methods – We measured 8 cladode traits (n = 20 cladodes for each floral morph) and 17 flower traits (n = 30 flowers per morph), and reproductive phenology was recorded for both morphs to describe their phenophases (n = 10 individuals per morph).

Key results and conclusion – We found that floral colour morphs of O. streptacantha showed significant differences mostly associated with flower traits. Principal component analysis revealed seven components that explained 80% of the total variation, namely total flower length, number of stamens, distance between anther and stigma, number of pollen grains, style length, equatorial diameter of the ovarian chamber, pericarp width, and number of areole lines. Some individuals of O. tomentosa were classified as floral morphs of O. streptacantha, not having a clear separation between the species. The phenology of the floral colour morphs showed a slight lag in their peak flowering and fruiting. Very high flowering synchrony was found for each floral morph and between them. The modifications found in the flowers of O. streptacantha may be associated with a possible hybridization with O. tomentosa favouring the appearance of the two floral morphs.

Authors: Yalçın Elif , Altıntaş Eyyüp , Tekin Samet
Published: July 2024

Occlusal splint is a treatment alternative that gives positive results in reducing the symptoms of temporomandibular diseases. This treatment involves placing an appliance made of various materials specifically for the cutting and chewing surfaces of the teeth. The most popular materials used in the construction of occlusal splints are soft and hard acrylic-based materials such as polymethylmethacrylate, ethylene vinyl acetate, polycarbonate, polyethylene terephthalate and polyetheretherketone. PEEK is a high performance, semi-crystalline, thermoplastic and thermally stable polymer belonging to the polyaryletherketone family. PEEK, which has very good dimensional stability against intraoral temperature changes, is not affected by the intraoral chemical environment. Since PEEK material is chemically stable, has high biocompatibility and abrasion resistance, its use as an occlusal splint material has become widespread today. The aim of this review is to provide information about occlusal splints produced using PEEK material and digital procedures, which are becoming increasingly popular in dentistry, and to contribute to the literature.
Embedding the advancement practice in South African universities : lessons from the Kresge Inyathelo Advancement Initiative (KIAI)
Authors:   , Sedumedi Mosimanegape David
Published: July 2024

The South African Higher Education academic enterprises are besieged with multiple challenges that threaten its viability. Both the government and academic leadership bemoan the dwindling fiscals and turbulent economic markets as factors contributing to this undesirable trajectory. This manifested in 2015, following the October student uprising over increases in student fees. Their main grievance was a call for zero-percent fee increase for the sector. The call later gravitated towards a demand for free education. Universities on the other hand, lament their dire need for student fees to augment the government funding to keep afloat. The impasse brought about by the students’ demand for free education on one hand, and the University’s quest for sustainability on the other, brought the South African Higher Education institutions’ viability model into scrutiny. Notwithstanding government’s obligation to public funding in a South African context, Universities are challenged to develop their own Advancement capacity to to mobilise resources from alternative funding sources. Advancement in this instance refers to a systematic and integrated approach to building and managing the external relationships with key constituencies and stakeholders thereby positioning an organisation to attract support (Inyathelo, 2015). This research is therefore aimed at contributing towards institutional Advancement body of knowledge, positioning it as a possible viability strategy. The study employs Stanford Beer’s (1981) Viable Systems Model’s diagnostic capability to analyse the Advancement practice to the end of informing organisational self-knowledge.

Social Media Political Communication and Misinformation: A Case Study of the Youth in Kiambu County, Kenya
Authors: Macharia Ann Wambui , Ong'ong'a Daniel Oloo
Published: July 2024

Social media in recent times has proven to be extremely persuasive in influencing the public’s opinion on political affairs. Since 2007, election campaigns have actively utilized several social media platforms in Kenya for communicating with, mobilizing, and organizing supporters. Politicians and political activists along with their parties make maximum use of it to interact and provide civic education to the public. However, few written materials are available on how Kenyan youth, particularly those who live in Kiambu County, use social media for political engagement. The objective of this research is therefore to explore patterns as well as practices characterizing social media use by young people in Kiambu County and how this affects their political involvement and discourse. This research is guided by Habermas’s Theory of the Public Sphere, which asserts that public political discourse that is free from government interference is important for creating functional democracies. Social media, which acts as a public sphere, can allow the youth to engage in political discussions and other civic activities. The research employs a descriptive research design, utilizing an online survey as the primary tool for data collection, administered via Survey Monkey. The research’s target population includes young people enrolled in institutions of higher learning in Kiambu County who use social media for communication. The sample size was determined based on the number of university students in Kiambu County. It utilized stratified random sampling on a target population of 115,330 to draw a sample of 380 youths using a Survey Monkey online sample calculator with a 95% confidence level and 5% margin of error. Initially, a pilot study was conducted on 10% of the sample, which is 38 respondents, to ascertain the reliability of the research instruments, eventually, from the 342 surveys sent out, 224 were completed and returned. For data analysis, Microsoft Excel was utilized in coding and organizing the data to create tables and graphs. The findings showed that X was the respondents' most used platform for political discourse. Most respondents were aware of and engaged in political discussions on social media, and believed that social media influenced their political attitudes and beliefs. Although most viewed social media as a source of civic education, they were skeptical about its reliability due to misinformation. The study concludes that many youths in Kiambu County are actively participating in political discussions online and therefore it recommends that better education should be provided to help the youth discern credible information from misinformation. Additionally, interventions should be established to curb digital crimes like cyberbullying and online fraud.
A PERDA DE MANDATO ELETIVO POR INFIDELIDADE PARTIDÁRIA: UMA ANÁLISE CRÍTICA DA JURISPRUDÊNCIA CONSOLIDADA
Authors: Cogo Eduardo Henrique Granja , Cavalcante Bruno de Souza
Published: July 2024

A presente pesquisa tem como título “A perda de mandato eletivo por infidelidade partidária: uma análise crítica da jurisprudência consolidada”. No atual sistema de democracia representativa no Brasil, destaca-se a concessão da sociedade a representantes eleitos para agir em seu nome. O texto enfatiza a importância dos partidos políticos nesse contexto, especialmente no que diz respeito à fidelidade partidária, que implica lealdade aos princípios e decisões da agremiação. Apesar de a Constituição prever a fidelidade, não estabelece sanções para violações, levando o Tribunal Superior Eleitoral a decidir em 2007 que o partido é o proprietário do mandato parlamentar. Recentemente, a jurisprudência rejeita a perda de mandato por infidelidade nos casos de expulsão partidária. A análise crítica ressalta o impacto dessas práticas na estabilidade democrática, levantando questionamentos sobre a propriedade do mandato pelo partido. A pesquisa, de natureza qualitativa, examina aspectos legais, morais e políticos, buscando compreender a legalidade das ações em nome da disciplina partidária e sua conformidade com princípios democráticos, como liberdade de expressão e participação.

Calpain 1 gene expression in liver tissue and the association of novel calpain 1 single-nucleotide polymorphisms (SNPs) with meat quality in Bali cattle
Authors:   Dairoh, Ulum Mokhamad Fakhrul , Sumantri Cece ,   Jakaria
Published: July 2024

Abstract. Calpain 1 (CAPN1) is an enzyme that influences meat tenderization, and it is involved in post mortem proteolysis. The bovine CAPN1 gene was chosen as a candidate gene for DNA sequencing to identify novel single-nucleotide polymorphisms (SNPs) in exons 8–10 and assess their associations with meat quality in Bali cattle. In an analysis of 95 Bali cattle, two novel SNPs (g.5327C>T and g.5959C>T) were identified in exons and four novel SNPs (g.5534C>T, g.5807A>C, g.5857G>A, and g.5869T>C) were discovered in introns. Allelic frequency was evaluated, and Hardy–Weinberg equilibrium was found for all SNPs in Bali cattle. The marbling score and intramuscular fat content as determined by ultrasound were associated with g.5869T>C and g.5959C>T. g.5327C>T was associated with pH and meat color in Bali cattle, whereas two other SNPs (g.5869T>C and g.5959C>T) were associated with Warner–Bratzler shear force and meat color. Furthermore, g.5869T>C was associated with linolenic acid content, and g.5959C>T with caprylic and linolenic acid levels. However, intronic SNPs (g.5534C>T, g.5807A>C, and g.5857G>A) did not significantly affect meat quality in Bali cattle. Quantitative real-time PCR of liver tissue revealed that the mRNA expression of CAPN1 significantly differed (P<0.05) among the CT, CC, and TT genotypes. The results suggest that genetic variability in loci within CAPN1 might be associated with meat quality in Bali cattle.
Disentangling the chemistry and transport impacts of the Quasi-Biennial Oscillation on stratospheric ozone
Authors: Xie Jinbo , Tang Qi , Prather Michael , Richter Jadwiga , Zhang Shixuan
Published: July 2024

Abstract. The quasi-biennial oscillation (QBO) in tropical winds perturbs stratospheric ozone throughout much of the atmosphere via changes in transport of ozone and other trace gases and via temperature changes that alter chemical processes. Here we separate the temperature-driven changes using the Department of Energy’s Energy Exascale Earth System Model version 2 (E3SMv2) with linearized stratospheric ozone chemistry. E3SM produces a natural QBO cycle in winds, temperature, and ozone. Our analysis defines climatological QBO patterns of ozone for the period 1979–2020 using both nonlinear principal component analysis and monthly composites centered on QBO phase shift. As a climate model, E3SM cannot predict the timing of the phase shift, but it does match these climatological patterns. We develop an offline version of our stratospheric chemistry module to calculate the steady-state response of ozone to temperature and overhead ozone perturbations, assuming that other chemical families involved in ozone chemistry remain fixed. We find a clear demarcation: ozone perturbations in the upper stratosphere (above 20-hPa) are predicted by the steady-state response of the ozone column to the temperature changes; while those in the lower stratosphere show no temperature response and are presumably driven by circulation changes. These results are important for diagnosing model-model differences in the QBO-ozone responses for climate projections.
The EnVision Mission to Venus – concept, science and status
Authors: Straume-Lindner Anne Grete , Pacros Anne , Schulte Mitch ,   EnVision Science Working Team and Project Team members
Published: July 2024

EnVision is ESA’s next mission to Venus in partnership with NASA, where NASA provides the Synthetic Aperture Radar payload and mission support. The mission was adopted in January 2024, entering phase B2/C/D/E. The launch is scheduled for 2031, and the start of the science operations at Venus is expected in early 2035 following the mission cruise and aerobraking phase around Venus to achieve a low Venus polar orbit. The scientific objective of EnVision is to provide a holistic view of the planet from its inner core to its upper atmosphere, studying the planets history, activity and climate. EnVision aims to establish the nature and current state of Venus’ geological evolution and its relationship with the atmosphere. EnVision’s overall science objectives are to: (i) characterize the sequence of events that formed the regional and global surface features of Venus, as well as the geodynamic framework that has controlled the release of internal heat over Venus history; (ii) determine how geologically active the planet is today; (iii) establish the interactions between the planet and its atmosphere at present and through time. Furthermore, EnVision will look for evidence of past liquid water on its surface.The nominal science phase of the mission will last six Venus cycles (~four Earth years), and ~210 Tbits of science data will be downlinked using a Ka-/X-band communication system. The science objectives will be addressed by five instruments and one experiment, provided by ESA member states and NASA. The VenSAR S-band radar will perform targeted surface imaging as well as polarimetric and stereo imaging, radiometry, and altimetry. The high-frequency Subsurface Radar Sounder (SRS) will sound the upper crust in search of material boundaries for the first time. Three spectrometers, VenSpec-U, VenSpec-H and VenSpec-M, operating in the UV and Near- and Short Wave-IR, respectively, will map trace gases, search for volcanic gas plumes above and below the clouds, and map surface emissivity and composition. A Radio Science Experiment (RSE) investigation will exploit the spacecraft Telemetry Tracking and Command (TT&C in Ka-/X bands) system to determine the planet’s gravity field and to sound the structure and composition of the middle atmosphere and the cloud layer in radio occultation. All instruments have heritage and robust margins relative to the requirements, with designs suitable for operation in the Venus environment, and chosen to meet the broad range of measurement requirements needed to support the EnVision scientific objectives. The EnVision science teams will adopt an open data policy, with public release of the scientific data after validation and verification. Public calibrated data availability is
Investigating the possibility of H2O2-induced warming on early Mars with a 3D GCM
Authors: Maurice Maxime , Forget François , Luo Yangcheng , Lefèvre Franck , Jaziri Yassin , Millour Ehouarn , Turbet Martin , Braude Ashwin
Published: July 2024

IntroductionLiquid water is largely regarded as a sine qua non condition for life as we know it. Geomorphological, mineralogical and sedimentological evidences indicate the presence of perennial liquid water on the surface of Mars in the late Noachian, approximately 3.8 billion years ago (Ga) [1,2], suggesting that it was possibly habitable. Today, the low surface temperature on Mars precludes sustained liquid water. The solar flux was fainter 3.8 Ga than today, leading to a conundrum regarding the conditions that allowed for perennial liquid water on early Mars.Although likely, a thicker (up to 2 bar) CO2 atmosphere on early Mars falls short of heating up the surface temperature to the melting point of water (273 K) [3]. Thus, other infrared opacity contributors are necessary to further enhance the greenhouse effect. Recently, [4] suggested that such additional greenhouse effect could be due to hydrogen peroxide (H2O2), and calculated that an average of 1 ppm H2O2 in a 2 bar CO2 atmosphere could raise the surface temperature to 273 K. Here we test this hypothesis using a global circulation model (the Generic PCM) and an H-C-O photochemical.ModelIn order to assess the possibility to produce H2O2, we adopted the most favorable conditions by optimizing the water content of the atmosphere, consider an already warm and wet early Mars. This was achieved by using the setup from [5], where warming is due to the collision-induced absorption of CO2 and H2. Notice that the high H2 content assumed in the radiative transfer calculation is unrelated to the chemical model. Within these simulations, we include the H-C-O photochemical network considering 14 species and 52 reactions (including 12 photodissociation reactions). Although not self-consistent, this scenario allows us to study the chemistry on a warm and wet early Mars.ResultsWe find that after 10 Martian years of evolution, the average amount of H2O2 starts to plateau. While the upper atmosphere has an H2O2 volume mixing ratio (VMR) above 1 ppm, the well-mixed lower atmosphere has an H2O2 VMR lower than 10-7 (Figure 1). This is likely too low to induce a sufficient greenhouse warming. Because we used the most favorable conditions for H2O2, this result suggests that a more realistic, initially cold and dry early Mars couldn't have been warmed up by the greenhouse effect of H2O2.Figure 1: Molar mixing ratio of the various species after 10 Martian years.References[1] Haberle et al.

The term “microsignatures” refers to localized decreases in trapped particle flux caused by particle absorption by moons or rings that orbit within a planetary magnetosphere. Microsignatures can survive for hours and thus propagate far from the parent moon and its magnetospheric interaction region. They thus evolve under the influence of the background magnetospheric environment, meaning that their profile and location can trace processes in the magnetosphere itself, such as particle transport. Microsignatures are most common in electrons from few keV and up to the ultra-relativistic range (>10 MeV). A large number of microsignature detections at Saturn has revolutionized our understanding of energetic particle transport processes in the planet’s radiation belts. However, to this date, we lack a comprehensive survey of satellite microsignatures at Jupiter, even though few single case studies demonstrate their detectability in both the Galileo and Juno datasets. To proceed with their detailed study at Jupiter, it is necessary to first develop a framework that allows us to predict their timing and verify under which conditions, geometries and energies such predictions are most successful. The complex magnetospheric configuration at Jupiter (compared to the spin-aligned magnetic field of Saturn) introduces several challenges. In this work, we present the first steps towards developing this framework and contrast our initial predictions against energetic particle observations by Juno. In particular, we identify over thirty microsignatures from Jupiter’s innermost moons (Metis, Adrastea, Amalthea and Thebe), which orbit in a region where the effects of magnetic field asymmetries are greatly enhanced. By testing the predicted against the observed timing of those events, we optimize our model and our predictions for the JUICE and Europa Clipper missions at the Galilean moons. The long and continuous residence of both missions in the inner magnetosphere, particularly close to the orbits of Europa, Ganymede and Callisto, would result in unique geometries and opportunities to probe Jupiter’s inner and middle magnetosphere with numerous microsignature observations.

Published: July 2024

BELA is the laseraltimeter of the ESA BepiColombo mission which was launched in 2018 and is currently on its way to Mercury and will arrive there in 2025, mission start is scheduled for early 2026. BELA is one of 11 instruments aboard the MPO (Mercury Planetary Orbiter) and the first laseraltimeter used on an interplanetary european mission. The main goal of BELA will be to provide a global topography map of Mercury, also to analyse the surface structure in terms of roughness and slopes, as well of measurements of the albedo.Since launch in October 2018 BELA was operated several times, namely during the NECP (Near Earth Commisioning Phase), 11 CCO (Crusie Checkout), during Mercury Flyby 3 and for SSMM (Solid State Mass Memory) test.We will present an overview of BELA, the main scientific goals, performance simulations and the results from operations so far.This includes the analysis of the received TM data to check if the instruments worked correctly.Also the poster will include the presentation of the used GRM (ground reference model) at DLR.
Consistent satellites tidal and rotational models for ephemerides estimation
Authors: Magnanini Andrea , Zannoni Marco
Published: July 2024

Tidal dissipation is fundamental to provides the energy that sustain natural satellites’ internal oceans, as identified in Europa and Enceladus, or Io’s volcanic activity. A proper modeling of the dissipative phenomena is crucial to correctly infer internal structure properties and composition.Tidal dissipation is responsible for orbital expansion of satellites. From the orbital expansion it is possible to estimate the amount of dissipation in the planet or the satellite, exploiting astrometric and radiometric observations.The two most used tidal models of satellites parametrize the tidal dissipation using a time lag (e.g. Mignard, 1980) or a phase lag (e.g. Eanes et al., 1983), respectively. Applying the models to ephemerides propagation, we found that they produce slightly different orbital effects for the satellite, with a difference of 3% in  semimajor axis and 15% in eccentricity. In this work we provide a possible strategy to reconciliate the two models.Moreover, regarding synchronous satellites tides, classical theoretical formulas from Yoder et al. (1981), Segatz et al. (1988), which assume that the prime meridian of the moon points to the empty focus of its orbit, predict an orbital energy dissipation which is equivalent to the following evolution of semimajor axis and eccentricity of the moon’s orbit:where Eq. (2) is found from conservation of the angular momentum.However, computing the secular orbital evolutions using Gauss planetary equations and considering the same rotational and tidal models, we found a difference in the derivative of the semi-major axis, which is directly related to the orbital energy, by almost a factor 3. This may bias the estimation of dissipation parameters from the orbital evolution by the same factor. In addition, during the orbital evolution the angular momentum is not conserved. In this work we analyze these inconsistencies between the energetic approach and the direct propagation of the dynamical equations from tidal potential. We argue that the difference may originate from the effect of the tidal dissipation on the moons rotational state, not considered in the classical approach were the prime meridian is imposed to point the empty focus.  Finally, we identify possible strategies to reconcile the propagation with theoretical predictions, ensuring the conservation of angular momentum.This may have important consequences in the estimation of the satellite ephemerides and tidal dissipation of the Jupiter system with the upcoming JUICE and Europa Clipper missions, whose unprecedented accuracy will require high-accuracy models of the dynamics inside the system.
The MINDS gas-rich debris disk sample observed with JWST/MIRI MRS
Authors: Samland Matthias ,   MINDS collaboration
Published: July 2024

Debris disks are the remnants of planet formation and therefore extremely important for understanding exoplanet system architecture. They were long thought to be completely depleted in gas, different from protoplanetary disks. In recent years, however, detections of CO gas in a number of debris disks has caused questions about the nature and origin of this class of gas-rich debris disks. A sample of five CO-rich debris disks has now been observed with JWST's MIRI Medium Resolution Spectrograph (MRS) as part of the MINDS (MIRI mid-INfrared Disk Survey) GTO program. Our program resulted in high quality spectra from 5 to 27 micron, which are spatially resolved for most of the targets providing a unique opportunity to gain new insights into these objects.For the first time this data allows us to conduct a sensitive search for mid-IR atomic and molecular emission lines and dust features in debris disks for which CO gas was detected with ALMA. It also allows us to map the spatial distribution of the dust as a function of wavelength for most of our targets, bridging the gap between optical/near infrared imaging observation and sub-millimeter observations. In this talk we present the first exciting results and highlights coming out of this JWST survey.
Thermophysical Modeling and Parameter Estimation for 3375 Asteroids 
Authors: Tan Hanjie , Durech Josef
Published: July 2024

Thermophysical modeling has emerged as a powerful tool for investigating the physical properties of asteroids. In this study, we applied thermophysical models (TPMs) to a dataset of 3375 asteroids, with half of these objects being modeled for the first time. By combining optical and infrared observations with advanced numerical techniques, we aimed to refine the physical parameters of these asteroids and explore potential correlations between their thermal inertia, albedo, and other characteristics.To address the complexities of asteroid thermophysical models, we employed the convex inversion thermophysical model (CITPM) to simultaneously optimize all relevant physical parameters of the asteroids, taking into account uncertainties in the shape models and rotation states [1]. Furthermore, we tackled the challenges posed by the extensive observational data by incorporating dense optical light curves, sparse light curves from various surveys, and thermal infrared data from WISE, AKARI, and IRAS. By integrating shape models derived from light curve inversion with multi-wavelength observational data, we aimed to provide a more comprehensive characterization of the thermal properties of these asteroids.Our methodology involved the use of the bootstrap method to optimize the observational data and the implementation of various input conditions for crater aperture and coverage on each asteroid's surface [2]. We explored the solutions under 81 different asteroid surface roughness input conditions to ensure the robustness of our results. The plausible range of physical parameter solutions was determined by evaluating the chi-squared values of the asteroid light curve fits.While the TPM method may not provide highly precise physical parameters, it offers a relatively efficient means to obtain reasonable estimates of these values. This comprehensive analysis not only expands our understanding of the thermophysical properties of a large number of asteroids but also lays the foundation for investigating correlations between these properties and various asteroid characteristics [3].The derived parameters were then analyzed to explore correlations with asteroid taxonomic classes, orbital properties, and other relevant characteristics. This extensive thermophysical modeling significantly expands our knowledge of asteroid physical properties and provides valuable insights into the processes that shaped our cosmic neighborhood. References:[1] Ďurech, J. et al.
