Publisher: name: Zenodo
Year: 2024

description: This document provides an overview of available open-access data for developing a framework to calculate the socio-economic and environmental (SEE) impacts of electronic products in the CE-RISE project. Using the Product Environmental Footprint (PEF) and its specific guidelines (PEFCR), the project aims to assess the environmental impacts across a product's life cycle. The report categorizes available data into bottom-up Life Cycle Inventory (LCI) data and top-down Input-Output (IO) and Supply Use Table (SUT) data. It notes the scarcity of open-access data for certain electronic products and outlines the data sources for assessing SEE impacts, focusing on pilot products like HVAC systems, solar panels, IT equipment, printers, and batteries. The document serves as an inventory for SEE-assessment data, with further investigation of proprietary data planned in a future work package.

description: We investigated the actuation performances of anisotropic gels driven by mechanical and chemical stimuli, in terms of both deformation processes and stroke--curves, and distinguished between the fast response of gels before diffusion starts and the asymptotic response attained at the steady state. We also showed as the range of forces that an anisotropic hydrogel can exert when constrained is especially wide;indeed, changing fiber orientation allows to induce shear as well as transversely isotropic extensions.

description: We report the results of optical polarimetric observations of a Bok globule CB34 to study magnetic field structure on large scales ($10^5-10^6$ AU), which is combined with archival sub-mm observations to characterize the magnetic field structure of CB34 on small scales ($10^4 - 10^5$ AU). The optical polarization measurements indicate that the magnetic field in the globule is constrained to a maximum radius of $10^5$AU around the core, out to densities not smaller than $10^4$cm$^{-3}$. Our study is mainly concentrated on two submillimeter cores C1 and C2 of CB34. The direction of magnetic field of core C2 is found to be nearly perpendicular to the CO outflow direction of the globule. The magnetic field of core C1 is almost aligned with the minor axis of the core which is typical for magnetically dominated star formation models. The mean value of offset between the minor axis of core C2 and the outflow direction is found to be $14^\circ$ which suggests that the direction of the outflow is almost aligned with the minor axis of core C2. The magnetic field strength in the plane-of-sky for cores C1 and C2 is estimated to be $\approx 34μ$G and $\approx 70μ$G.

description: We report on INTEGRAL, Swift and XMM-Newton observations of IGR J17511-3057 performed during the outburst that occurred between March 23 and April 25, 2015. The source reached a peak flux of 0.7(2)E-9 erg/cm$^2$/s and decayed to quiescence in approximately a month. The X-ray spectrum was dominated by a power-law with photon index between 1.6 and 1.8, which we interpreted as thermal Comptonization in an electron cloud with temperature > 20 keV . A broad (σ ~ 1 keV) emission line was detected at an energy (E = 6.9$^{+0.2}_{-0.3}$ keV) compatible with the Kα transition of ionized Fe, suggesting an origin in the inner regions of the accretion disk. The outburst flux and spectral properties shown during this outburst were remarkably similar to those observed during the previous accretion event detected from the source in 2009. Coherent pulsations at the pulsar spin period were detected in the XMM-Newton and INTEGRAL data, at a frequency compatible with the value observed in 2009. Assuming that the source spun up during the 2015 outburst at the same rate observed during the previous outburst, we derive a conservative upper limit on the spin down rate during quiescence of 3.5E-15 Hz/s. Interpreting this value in terms of electromagnetic spin down yields an upper limit of 3.6E26 G/cm$^3$ to the pulsar magnetic dipole (assuming a magnetic inclination angle of 30°). We also report on the detection of five type-I X-ray bursts (three in the XMM-Newton data, two in the INTEGRAL data), none of which indicated photospheric radius expansion.

description: On March 5, 1921, Albrecht Penck spoke at the "Neue Börse" in Leipzig under the title "Der Großgau im Herzen Deutschlands". In his speech, one of the most influential geographers of his time combined previously separate motifs into a powerful overall concept. Penck's presentation was a programmatic prelude to the institutionalization of völkisch "Mitteldeutschland" research in Leipzig. It is almost astonishing to see, using the example of "Mitteldeutschland", how geographers, historians, archaeologists, and spatial planners first gave a name to an idea, then visualized it on maps, "found" matching "natural" prefigurations, archaeological artifacts, and a supra-temporal history, in order to finally, through the reorganization of existing administrative boundaries, actually want to create the previously imagined entity as a state-constituted "living space" of a "mitteldeutschen Menschen". Hans-Dietrich Schultz: "It was, [Otto] Schlüter announced, 'as if the essence of the whole of Germany were increased in its central part'. Parallels to the simultaneously running völkisch construction of a "German nation" are obviously no coincidence. This article provides background information on the genesis of the academic use of the indefinable term "Mitteldeutschland". Its use allows us to study the impotence of the Protestant-influenced Prussian academic elite in dealing with "secular sacrality" (Lutz Hoffmann). The nonsensical work on a phantom demonstrates the power of sacral concepts, once they are detached from their religious context and can develop a demonic life of their own.

description: Excerpts: This study explored consumer reactions to six new product concepts. A split sample technique lightened the burden on the respondent, i.e., each respondent considered only three of the six product concepts. Each color-coded version of the questionnaire--blue and white--surveyed a different set of three product concepts: White -- Dehydrated sugar-coated fruit slices, Fruit packed in juice of different fruit, and Frozen fresh Bartlett pears. Blue -- Carbonated apple beverages, Dehydrated instant applesauce, and Whole cored frozen baking apples. The data reported simply represent homemakers' reactions to new product concepts. Since little or no attempt was made to inform the respondents as to how these products might be packaged or priced, it would be misleading to conclude that a verbal expression of interest reflects any firm intent to purchase these products.
description: Preliminary Survey Results -- Data were collected during March and April 1973 in personal interviews with 1,116 homemakers--the persons with major responsibility for decisions on purchasing food items for household use. The sample was a regional probability sample consisting of two geographic divisions as defined by the Bureau of Census--Mid-Atlantic (New York, New Jersey, Pennsylvania) and East North Central (Ohio, Indiana, Illinois, Michigan, Wisconsin). The completion rate was 74 percent.

description: We investigate patterns of critical current as a function of perpendicular and in-plane magnetic fields in superconductor-semiconductor-superconductor (SNS) junctions based on InAs/InGaAs heterostructures with an epitaxial Al layer. This material system is of interest due to its exceptionally good superconductor-semiconductor coupling, as well as large spin-orbit interaction and g-factor in the semiconductor. Thin epitaxial Al allows the application of large in-plane field without destroying superconductivity. For fields perpendicular to the junction, flux focusing results in aperiodic node spacings in the pattern of critical currents known as Fraunhofer patterns by analogy to the related interference effect in optics. Adding an in-plane field yields two further anomalies in the pattern. First, higher order nodes are systematically strengthened, indicating current flow along the edges of the device, as a result of confinement of Andreev states driven by an induced flux dipole; second, asymmetries in the interference appear that depend on the field direction and magnitude. A model is presented, showing good agreement with experiment, elucidating the roles of flux focusing, Zeeman and spin-orbit coupling, and disorder in producing these effects.

description: With the participation in automatic generation control (AGC), a large-scale wind farm should distribute the real-time AGC signal to numerous wind turbines (WTs). This easily leads to an expensive computation for a high-quality dispatch scheme, especially considering the wake effect among WTs. To address this problem, a hierarchical power control (HPC) is constructed based on the geographical layout and electrical connection of all the WTs. Firstly, the real-time AGC signal of the whole wind farm is distributed to multiple decoupled groups in proportion of their regulation capacities. Secondly, the AGC signal of each group is distributed to multiple WTs via the data-driven surrogate-assisted optimization, which can dramatically reduce the computation time with a small number of time-consuming objective evaluations. Besides, a high-quality dispatch scheme can be acquired by the efficient local search based on the dynamic surrogate. The effectiveness of the proposed technique is thoroughly verified with different AGC signals under different wind speeds and directions.
The Strait of Messana in the Roman world: connectivity, space, and identity between Italy and Sicily (300 BCE – 400 CE)
Creators: name: McKenzie, Jessica
Publisher: name: Macquarie University

description: The Strait of Messana separates Italy from Sicily by only a few kilometres of famously turbulent sea. During the Roman period, the Strait was at times described as a bridge and gateway to opportunity, a symbol of empire, and little more than a river easily forded. At others, it was an insurmountable divide, the most dangerous of all passages, and a hard boundary between Romans and non-Romans. In both contexts, the Strait continued to operate as an agent of connectivity, the crossroads of varied cultural groups from across the ancient Mediterranean, situated as it was between the Tyrrhenian and Ionian seas. Prior studies of the Strait and the major cities on its shores – Messana and Rhegium – have focused predominantly on pre-Roman histories and archaeology, while studies on wider processes in Roman Sicily and South Italy often put the Strait to one side due to a comparative lack of textual and archaeological evidence, or do not sufficiently consider the porous nature of the ‘boundary’ between Sicily and Italy. This thesis explores the tripartite nature of the Strait of Messana as bridge, division, and crossroads in the Roman period, arguing for the application of a globalising interpretative framework which prioritises emic perspectives in studies of space. It demonstrates how the Strait of Messana, as a geographical, rhetorical, and political space, facilitated, dictated, and at times restricted the socio-cultural transformations and processes taking place in Messana and Rhegium between 300 BCE and 400 CE and offers future studies in regional histories or identity studies a framework for studying identities across boundaries under the Roman Empire.

description: Single pulses preserve information about the pulsar radio emission and propagation in the pulsar magnetosphere, and understanding the behaviour of their variability is essential for estimating the fundamental limit on the achievable pulsar timing precision. Here we report the findings of our analysis of single pulses from PSR J1713+0747 with data collected by the Large European Array for Pulsars (LEAP). We present statistical studies of the pulse properties that include distributions of their energy, phase and width. Two modes of systematic sub-pulse drifting have been detected, with a periodicity of 7 and 3 pulse periods. The two modes appear at different ranges of pulse longitude but overlap under the main peak of the integrated profile. No evidence for pulse micro-structure is seen with a time resolution down to 140 ns. In addition, we show that the fractional polarisation of single pulses increases with their pulse peak flux density. By mapping the probability density of linear polarisation position angle with pulse longitude, we reveal the existence of two orthogonal polarisation modes. Finally, we find that the resulting phase jitter of integrated profiles caused by single pulse variability can be described by a Gaussian probability distribution only when at least 100 pulses are used for integration. Pulses of different flux densities and widths contribute approximately equally to the phase jitter, and no improvement on timing precision is achieved by using a sub-set of pulses with a specific range of flux density or width.

description: Fine-structure dynamics in solar prominences holds critical clues to understanding their physical nature of significant space-weather implications. We report evidence of rotational motions of horizontal helical threads in two active-region prominences observed by the \emph{Hinode} and/or \emph{IRIS} satellites at high resolution. In the first event, we found transverse motions of brightening threads at speeds up to 55~km~s$^{-1}$ seen in the plane of the sky. Such motions appeared as sinusoidal space--time trajectories with a typical period of $\sim$390~s, which is consistent with plane-of-sky projections of rotational motions. Phase delays at different locations suggest propagation of twists along the threads at phase speeds of 90--270~km~s$^{-1}$. At least 15 episodes of such motions occurred in two days, none associated with any eruption. For these episodes, the plane-of-sky speed is linearly correlated with the vertical travel distance, suggestive of a constant angular speed. In the second event, we found Doppler velocities of 30--40~km~s$^{-1}$ in opposite directions in the top and bottom portions of the prominence, comparable to the plane-of-sky speed. The moving threads have about twice broader line widths than stationary threads. These observations, when taken together, provide strong evidence for rotations of helical prominence threads, which were likely driven by unwinding twists triggered by magnetic reconnection between twisted prominence magnetic fields and ambient coronal fields.

description: An attractor of a piecewise-smooth continuous system of differential equations can bifurcate from a stable equilibrium to a more complicated invariant set when it collides with a switching manifold under parameter variation. Here numerical evidence is provided to show that this invariant set can be chaotic. The transition occurs locally (in a neighbourhood of a point) and instantaneously (for a single critical parameter value). This phenomenon is illustrated for the normal form of a boundary equilibrium bifurcation in three dimensions using parameter values adapted from of a piecewise-linear model of a chaotic electrical circuit. The variation of a secondary parameter reveals a period-doubling cascade to chaos with windows of periodicity. The dynamics is well approximated by a one-dimensional unimodal map which explains this bifurcation structure. The robustness of the attractor is also investigated by studying the influence of nonlinear terms.

description: Breast cancer is the leading cancer in both incidence and mortality for Asian Indian women. The breast cancer screening rates for Asian Indians are also among the lowest across several racial and ethnic groups in the United States (US). However, few studies have investigated factors associated with breast cancer screening rates for Asian Indian women in the US. The objective of this study was to assess sociocultural predictors of adherence to American Cancer Society breast cancer screening g uidelines for Asian Indian women residing in the greater Houston area. We hypothesized that low knowledge of breast cancer/breast cancer screening and negative attitudes such as stigma toward breast cancer screening would be significant predictors of adherence to screening guidelines. Surveys were designed using a Knowledge, Attitudes, Practices (KAP) analysis framework and were distributed to a convenience sample of 104 India-born Asian Indian women over the age of 45. Knowledge was measured using true/false questions about breast cancer and breast cancer screening. Attitude was measured using agree/disagree statements related to perceived stigma, internalized stigma, and sociocultural barriers to breast cancer screening. Multivariable logistic regression analysis revealed that attitude was a significant predictor of adherence to screening guidelines [OR = 0.858 (95% CI: 0.768 - 0.937); P = 0.002], but knowledge was not [OR = 1.16 (95% CI: 0.478 - 2.759); P = 0.736]. The findings from this study can guide the development of educational interventions that focus on improving health literacy and increasing breast cancer screening adherence for Asian Indian women.

description: A diverse range of natural and artificial self-propelled particles are known and are used nowadays. Among them, active Brownian particles (ABPs) and run-and-tumble particles (RTPs) are two important classes. We numerically study non-interacting ABPs and RTPs strongly confined to different maze geometries in two dimensions. We demonstrate that by means of geometrical confinement alone, ABPs are separable from RTPs. By investigating Matryoshka-like mazes with nested shells, we show that a circular maze has the best filtration efficiency. Results on the mean first-passage time reveal that ABPs escape faster from the center of the maze, while RTPs reach the center from the rim more easily. According to our simulations and a rate theory, which we developed, ABPs in steady state accumulate in the outermost region of the Matryoshka-like mazes, while RTPs occupy all locations within the maze with nearly equal probability. These results suggest a novel technique for separating different types of self-propelled particles by designing appropriate confining geometries without using chemical or biological agents.

Dynamics and Protecting of Entanglement in Two-Level Systems Interacting with a Dissipative Cavity: The Gardiner-Collett Approach

description: In this paper, we study the exact entanglement dynamics of two two-level atoms in a dissipative cavity. We use the Gardiner-Collett Hamiltonian to model the dissipative cavity, in which, we assume that the two atoms resonantly interact with the cavity field and the cavity field itself interacts with the surrounding medium. Then, with the help of the Fano's technique, we show that, this system can be regarded as two atoms interacting with a heat bath. In such a case, we find that, there exists a decoherence-free state that does not evolve in time. At this time, there exists a so-called super-radiant state which decays in time due to dissipation. At last, we use the quantum Zeno effect to preserve the entanglement which already has been stored in the system.

A note on the reverse mathematics of the sorites
Creators: name: Dzhafarov, Damir D.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Logic (math.LO)

description: Sorites is an ancient piece of paradoxical reasoning pertaining to sets with the following properties: (Supervenience) elements of the set are mapped into some set of "attributes", (Tolerance) if an element has a given attribute then so are the elements in some vicinity of this element, and (Connectedness) such vicinities can be arranged into pairwise overlapping finite chains connecting two elements with different attributes. Obviously, if Superveneince is assumed, then (1) Tolerance implies lack of Connectedness, and (2) Connectedness implies lack of Tolerance. Using a very general but precise definition of "vicinity", Dzhafarov and Dzhafarov (2010) offered two formalizations of these mutual contrapositions. Mathematically, the formalizations are equally valid, but in this paper, we offer a different basis by which to compare them. Namely, we show that the formalizations have different proof-theoretic strengths when measured in the framework of reverse mathematics: the formalization of (1) is provable in $\mathsf{RCA}_0$, while the formalization of (2) is equivalent to $\mathsf{ACA}_0$ over $\mathsf{RCA}_0$. Thus, in a certain precise sense, the approach of (1) is more constructive than that of (2).

description: New experimental results on bacterial growth inspire a novel top-down approach to study cell metabolism, combining mass balance and proteomic constraints to extend and complement Flux Balance Analysis. We introduce here Constrained Allocation Flux Balance Analysis, CAFBA, in which the biosynthetic costs associated to growth are accounted for in an effective way through a single additional genome-wide constraint. Its roots lie in the experimentally observed pattern of proteome allocation for metabolic functions, allowing to bridge regulation and metabolism in a transparent way under the principle of growth-rate maximization. We provide a simple method to solve CAFBA efficiently and propose an "ensemble averaging" procedure to account for unknown protein costs. Applying this approach to modeling E. coli metabolism, we find that, as the growth rate increases, CAFBA solutions cross over from respiratory, growth-yield maximizing states (preferred at slow growth) to fermentative states with carbon overflow (preferred at fast growth). In addition, CAFBA allows for quantitatively accurate predictions on the rate of acetate excretion and growth yield based on only 3 parameters determined by empirical growth laws.

Investigating blood plasma levels of cytokines and amyloid-β as potential diagnostic biomarkers for preclinical Alzheimer’s disease
Creators: name: Elmi, Mitra
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Alzheimer’s disease (AD) is the most common form of dementia, but to date there is no effective treatment. Therefore, preclinical diagnosis is necessary to prevent or improve therapeutic approaches for disease management. Mounting evidence shows that inflammatory processes involving various pro-inflammatory cytokines including interleukin (IL)-1β, IL-6 and tumour necrosis factor (TNF)-α contribute to AD pathogenesis. While inflammatory biomarkers have been extensively studied in clinically diagnosed AD subjects, there has been a paucity of information on inflammatory biomarkers in cognitively normal elderly subjects with a high neocortical amyloid-β load (NAL). Based on the findings of increased pro-inflammatory cytokines in clinical AD, I hypothesised that plasma levels of these cytokines are also increased in preclinical AD, and these increased cytokine levels may have diagnostic value, and functionally play a role in impairing cognition. In this study, approximately 100 plasma samples from healthy elderly adults with either high or low NAL were assessed for pro-inflammatory cytokines using conventional enzyme-linked immunosorbent assay (ELISA) kits. Furthermore, since plasma beta amyloid (Aβ) levels have recently been demonstrated to be altered in clinical AD, I investigated the levels of this peptide in preclinical AD. The Aβ results, which were expressed as the ratio of amyloid beta (Aβ) 40/42 were compared between low and high NAL subjects. The data collected were analysed using the statistical package for social sciences (SPSS). No significant differences in the plasma levels of all the pro-inflammatory cytokines were observed between the two groups, although there was a consistent trend of increased levels in the high NAL group. However, the ratio of Aβ 40/42 was significantly higher in the high NAL group compared to the low NAL, and receiver operating characteristic (ROC) curves were created to evaluate predictive models. The accuracy of prediction was increased when Aβ 40/42 was added to the base model. In conclusion, while the pro-inflammatory cytokines do not show promise as preclinical AD biomarkers based on the conventional ELISA assays used, the ratio of Aβ 40/42 is a potential candidate that merits inclusion in a diagnostic panel of biomarkers for preclinical diagnosis of AD.

description: We investigate how the presence of quantum correlations can influence work extraction in closed quantum systems, establishing a new link between the field of quantum non-equilibrium thermodynamics and the one of quantum information theory. We consider a bipartite quantum system and we show that it is possible to optimise the process of work extraction, thanks to the correlations between the two parts of the system, by using an appropriate feedback protocol based on the concept of ergotropy. We prove that the maximum gain in the extracted work is related to the existence of quantum correlations between the two parts, quantified by either quantum discord or, for pure states, entanglement. We then illustrate our general findings on a simple physical situation consisting of a qubit system.

description: It has been observed that photons in the prompt emission of some gamma-ray bursts (GRBs) are highly polarized. The high polarization is used by some authors to give a strict constraint on the Lorentz invariance violation (LIV). If the Lorentz invariance is broken, the polarization vector of a photon may rotate during its propagation. The rotation angle of polarization vector depends on both the photon energy and the distance of source. It is believed that if high polarization is observed, then the relative rotation angle (denoted by $α$) of polarization vector of the highest energy photon with respect to that of the lowest energy photon should be no more than $π/2$. Otherwise, the net polarization will be severely suppressed, thus couldn't be as high as what was actually observed. In this paper, we will give a detailed calculation on the evolution of GRB polarization arising from LIV effect duration the propagation. It is shown that the polarization degree rapidly decrease as $α$ increases, and reaches a local minimum at $α\approx π$, then increases until $α\approx 3π/2$, after that decreases again until $α\approx 2π$, etc. The polarization degree as a function of $α$ oscillates with a quasi-period $T\approx π$, while the oscillating amplitude gradually decreases to zero. Moreover, we find that a considerable amount (more than $60\%$ of the initial polarization) of polarization degree can be conserved when $α\approx π/2$. The polarization observation in a higher and wider energy band, a softer photon spectrum, and a higher redshift GRB is favorable in order to tightly constrain LIV effect.

description: 5. Senecio tridentatus DC., Prodr. 6: 424. 1838, syn. nov.
 Lectotypus (designated here): ARGENTINA /URUGUAY: sine loco, s.d., Haenke s.n. (PRC [PRC453191] image!; isolecto-: P [P01816571] image!, PR-616648 image!).
 = Senecio crassiflorus (Poir.) DC., Prodr. 6: 412. 1838. Cineraria crassiflora Poir., Encycl., Suppl. 2(1): 267. 1811. Holotypus: ARGENTINA. Prov. Buenos Aires: Buenos Aires, s.d., Commerson s.n. (P-LA [P00342427] image!).
 Notes. – CANDOLLE (1838) indicated “Peruviâ” as the provenance of the original material of Senecio tridentatus. Any information in this regard lacks in the three type specimens we studied. DILLON & HENSOLD (1993) stated that the presence of this species in Peru remained to be confirmed and VISION & DILLON (1996) recorded it with no information about its distribution. The study of the type material reveals that S. tridentatus is identical to S. crassiflorus, a very distinctive species frequent in the sandy shore habitats of SE Brazil, Uruguay, and E Argentina (F REIRE et al., 2014). It is a rhizomatous perennial herb characterized by having whitish-lanate indumentum covering most parts of the plant, leaves oblanceolate, attenuate at base, dentate at upper half to tridentate at apex (sometimes entire or almost so), capitula radiate, large, arranged in lax corymbiform synflorescences or solitary, composed of 21–25 involucral bracts, and achenes c. 5 mm long, pubescent.
 As in the case of Senecio adscendens (see above), the species S. crassiflorus is not rare in the region of Río de la Plata (ARECHAVALETA, 1906; CABRERA, 1963; F REIRE et al., 2014). Then, Haenke most probably collected it during the three months that he remained between Montevideo and Buenos Aires or when he left the latter city westward to Mendoza, Santiago, and Valparaíso. Mislabeling in Haenke’s specimens is well documented, and therefore, the name S. tridentatus is included in the synonymy of S. crassiflorus.
 The type material of Cineraria crassiflora Poir. is known from a single specimen in P-LA collected by Philibert Commerson (1727 – 1773) in Buenos Aires. Another collection by Commerson made in November 1767 shows the locality Montevideo; in disagreement with F REIRE et al. (2014), we prefer do not consider it as original material because of the mismatch in the locality.

description: The giant Herbig-Haro object 222 extends over $\sim$6$'$ in the plane of the sky, with a bow shock morphology. The identification of its exciting source has remained uncertain over the years. A non-thermal radio source located at the core of the shock structure was proposed to be the exciting source. However, Very Large Array studies showed that the radio source has a clear morphology of radio galaxy and a lack of flux variations or proper motions, favoring an extragalactic origin. Recently, an optical-IR study proposed that this giant HH object is driven by the multiple stellar system V380 Ori, located about 23$'$ to the SE of HH 222. The exciting sources of HH systems are usually detected as weak free-free emitters at centimeter wavelengths. Here we report the detection of an elongated radio source associated with the Herbig Be star or with its close infrared companion in the multiple V380 Ori system. This radio source has the characteristics of a thermal radio jet and is aligned with the direction of the giant outflow defined by HH~222 and its suggested counterpart to the SE, HH~1041. We propose that this radio jet traces the origin of the large scale HH outflow. Assuming that the jet arises from the Herbig Be star, the radio luminosity is a few times smaller than the value expected from the radio-bolometric correlation for radio jets, confirming that this is a more evolved object than those used to establish the correlation.

description: We have derived the abundances of 36 chemical elements in one Cepheid star, ASAS 181024--2049.6, located R$_{\rm G}= 2.53$ kpc from the Galactic center. This star falls within a region of the inner thin disc poorly sampled in Cepheids. Our spectral analysis shows that iron, magnesium, silicon, calcium and titanium LTE abundances in that star support the presence of a plateau-like abundance distribution in the thin disc within 5 kpc of the Galactic center, as previously suggested by \cite{Maret15}. If confirmed, the flattening of the abundance gradient within that region could be the result of a decrease in the star formation rate due to dynamic effects, possibly from the central Galactic bar.

description: Introduction : Le syndrome de Crouzon est généralement diagnostiqué dès la petite enfance en raison de sa présentation clinique évidente avec des anomalies cranio-faciales assez typiques. Cependant, dans de rares cas, il est possible de faire le diagnostic tardivement, lorsque les caractéristiques craniofaciales ne deviennent évidentes qu'après la période de croissance de l'enfant ou lorsque des complications secondaires, telles que des problèmes dentaires ou orthodontiques, incitent à une évaluation médicale approfondie. Le présent cas clinique rapporte deux frères et sœurs, présentant un morphotype facial inhabituel, une dysmorphose maxillomandibulaire associée à un retard d'éruption dentaire important, découvert lors d'une évaluation orthodontique. Observation : C’est le cas de deux enfants M.H et M.S, une fille de 13 ans et un garçon de 10 ans, dans une fratrie de 3 enfants et qui présentent des anomalies cranio-faciales atypiques associées à un sérieux retard d'éruption dentaire, découverts lors d'une évaluation orthodontique. Les examens cliniques et radiographiques ont révélé des caractéristiques morphologiques faciales particulières, notamment une hypoplasie maxillaire, une hypertélorisme, et une dysmorphose maxillomandibulaire, confirmant ainsi les soupçons de syndrome de Crouzon. Les patients ont été examinés par un rhumatologue et soumis à un examen clinique exhaustif, incluant une évaluation morphologique faciale, une analyse radiographique, et des investigations génétiques ciblées (recherche de mutations du gène FGFR2). Les résultats de ces investigations étaient toutes dans le sens du diagnostic d’un syndrome de Crouzon. Discussion: Le syndrome de Crouzon est une maladie génétique rare caractérisée par des anomalies craniofaciales précoces. Cependant, les cas à découverte tardive sont rares et posent un défi diagnostique. Le rôle de l'orthodontiste a été crucial dans la détection précoce de cette affection chez ces deux cas, il est important de penser à cette pathologie devant des anomalies maxillo-mandibulaires chez les enfants, le diagnostic précoce de ce syndrome permet dans certains cas une intervention médicale et chirurgicale précoce pour atténuer certaines complications sévères associées à une croissance cranio-faciale anormale et une dysmorphose maxillo-mandibulaire invalidante. Conclusion : Ce cas clinique souligne l'importance de la collaboration interdisciplinaire entre orthodontistes et rhumatologues dans le diagnostic de certaines formes du syndrome de Crouzon, en particulier dans les cas à découverte tardive. Une intervention médicale et chirurgicale précoce peut améliorer la qualité de vie et les résultats fonctionnels de ces patients.
