Résumé :

Abstract It was recently proposed that there exists a “gateway” in the orbital parameter space through which Centaurs transition to Jupiter-family comets (JFCs). Further studies have implied that the majority of objects that eventually evolve into JFCs should leave the Centaur population through this gateway. This may be naively interpreted as gateway Centaurs being pristine progenitors of JFCs. This is the point we want to address in this work. We show that the opposite is true: gateway Centaurs are, on average, more thermally processed than the rest of the population of Centaurs crossing Jup

Résumé :

Abstract Centaurs are an ephemeral class of objects that can evolve into Jupiter-family comets (or JFCs) due to gravitational perturbations from the giant planets. In this work, we use numerical integration of massless test particles in the six-body problem (the Sun, four giant planets, and a test particle) to study the transformation of Centaurs into JFCs. We find that Centaurs can transform into JFCs via a rapid, continuous drop in perihelion or aphelion distance to a value below 5.2 au or 7 au, respectively, typically within 5 yr from the start of the drop. We call these JFC perihelion drop

Résumé :

Abstract Jupiter-family comets (JFCs) have orbital periods of less than 20 yr and therefore undergo more frequent sublimation compared to other comet populations. The JFCs therefore represent the ideal dynamical population for investigating the dust production rates at high cadence. We analyzed observations by the Asteroid Terrestrial-impact Last Alert System (ATLAS) of 74 JFCs that reached perihelion in 2022 and 2023. The work contained in this study builds on our previous work, for a total of 116 JFCs over a 4 yr period. Using the Afρ parameter, we measured the dust production rates of each

Imaging showed hypointensity on T1- and T2-weighted magnetic resonance images which can be very well appreciated on a completely calcified computed tomography mass arising from the right L3/4 facet joint.

Abstract Jupiter-family comets (JFCs) exhibit a wide range of activity levels and mass loss over their orbits. We analyzed high-cadence observations of 42 active JFCs with the wide-field Asteroid Terrestrial-impact Last Alert System (ATLAS) in 2020–2021. We measured the dust production rates of the JFCs using the Af ρ parameter and its variation as a function of heliocentric distance. There is a tendency for our JFC sample to exhibit a maximum Af ρ after perihelion, with 254P/McNaught and P/2020 WJ5 (Lemmon) having their maximum Af ρ over a year after perihelion.

Abstract Neutrophils kill microorganisms using microbicidal products that they release into the phagosome or the extracellular space. Mature neutrophils contain four types of exocytosable storage organelles: azurophilic granules that contain myeloperoxidase, specific granules, gelatinase granules and secretory vesicles. Since the uncontrolled release of the contents of these organelles is potentially harmful, granule exocytosis must be tightly regulated. However, the secretory machinery utilized by neutrophils is poorly characterized. Here, we evaluate the role of Rab27a and its effector JFC1

Résumé :

College life is a critical period during which students are particularly vulnerable to developing unhealthy dietary behaviors. This study assessed the socio-demographic determinants of junk food consumption (JFC) among higher education students. A quantitative cross-sectional study was conducted using a self-administered survey questionnaire among 272 university students studying at the Central Department of Education, TU. The findings revealed that although only six percent of students preferred to consume junk food, a surprisingly high proportion (83.5%) reported consuming it. Peer pressure

This article aims to analyze the representation of Jember culture in the Jember Fashion Carnival (JFC) using Stuart Hall's representation theory approach. The main concepts applied in this analysis are change and resistance, which are used to understand how cultural symbols are represented and interpreted in JFC. The data collection process was carried out through literature study. Where the data obtained comes from the results of research and scientific work of other people which is studied and then developed.

Résumé :

In this study, a nonionic surfactant (JFC-M) was used as an additive for hydrothermal pretreatment of crushed poplar wood. The pseudo-lignin extracted from holocellulose after hydrothermal pretreatment was characterized, and the composition of liquid and solid fractions obtained after pretreatment at different experimental conditions was analyzed. The results showed that the addition of JFC-M surfactant accelerated the dissolution of biomass cellulose and effectively inhibited the production of pseudo-lignin in hydrothermal processes, under the same hydrothermal pretreatment conditions.

Résumé :

This ethnography is an inquiry on the transcultural identity of Japanese-Filipino Children (JFC) who are situated in a multi-cultural context in the city of Tokyo, Japan. In theoretical sense, the analysis centers on culturally nomadic individuals who are active agents in the formation of their cultural identities, rather than being passive repository of social and cultural influences. The cultural identities of JFC are navigated within a transcultural milieu that is perpetuated by Japanese and Filipino cultural background of their parents. The salient cultural identities of JFC include being

Comet 21P is a well-known member of the carbon-chain-depleted family, but also displays a depletion of amines. We continuously monitored the comet over more than seven months with the two TRAPPIST telescopes (TN and TS), covering a wide heliocentric distance range from 1.60 au inbound to 2.10 au outbound with a perihelion at 1.01 au on September 10, 2018.

Abstract We present a dynamical study of 39 active Centaurs and 17 high-perihelion (q > 4.5 au) Jupiter-family comets (JFCs) with a focus on investigating recent orbital changes as potential triggers for comet-like activity. We have identified a common feature in the recent dynamical histories of all active Centaurs and JFCs in our sample that is not present in the history of the majority of inactive population members: a sharp decrease in semimajor axis and eccentricity occurring within the past several hundred years prior to observed activity. We define these rapid orbital changes as “a-j

Cell function requires the integration of cytoskeletal organization and membrane trafficking. Small GTP-binding proteins are key regulators of these processes. We find that EPI64, an apical microvillar protein with a Tre-2/Bub2/Cdc16 (TBC) domain that stabilizes active Arf6 and has RabGAP activity, regulates Arf6-dependent membrane trafficking. Expression of EPI64 in HeLa cells induces the accumulation of actin-coated vacuoles, a distinctive phenotype seen in cells expressing constitutively active Arf6. Expression of EPI64 with defective RabGAP activity does not induce vacuole formation. Coexp
