Published: February 2023

Mit der steigenden Komplexität der Entwicklung mechatronischer Produkte sind den beteiligten Akteuren die Wirkbeziehungen zwischen den Bauteilen sowie zwischen den Bauteilen und den erforderlichen Produktionsprozessen oft nicht mehr hinreichend bekannt. Nicht abgestimmte Entscheidungen und Handlungen sind die Folge, die zu Kosten- und Terminüberschreitungen führen. Dieser Beitrag zeigt mögliche Innovationspotenziale auf, die ein Assistenzsystem für das Komplexitätsmanagement bieten kann.

Due to the increasing complexity in developing mechatronic products, often the stakeholders involved are no more aware of the interrelationships between components as well as between the components and the required production processes. This results in non-coordinated decisions and actions, leading to cost and schedule overruns. This article shows how an assistance system for complexity management can offer potential for innovation.

Abstract
We report the discovery of TOI-4562b (TIC-349576261), a Jovian planet orbiting a young F7V-type star, younger than the Praesepe/Hyades clusters (<700 Myr). This planet stands out because of its unusually long orbital period for transiting planets with known masses (P

Alongside the four available TESS transits, we performed follow-up photometry using the South African Astronomical Observatory node of the Las Cumbres Observatory and spectroscopy with the CHIRON spectrograph on the 1.5 m SMARTS telescope.

J for TOI-4562b. The radius of the planet is consistent with contraction models describing the early evolution of the size of giant planets. We detect tentative transit timing variations at the ∼20 minutes level from five transit events, favoring the presence of a companion that could explain the dynamical history of this system if confirmed by future follow-up observations. With its current orbital configuration, tidal timescales are too long for TOI-4562b to become a hot Jupiter via high-eccentricity migration though it is not excluded that interactions with the possible companion could modify TOI-4562b’s eccentricity and trigger circularization. The characterization of more such young systems is essential to set constraints on models describing giant-planet evolution.
GALFIT-ing AGN Host Galaxies in COSMOS: HST versus Subaru
Authors: Dewsnap Callum , Barmby Pauline , Gallagher Sarah C. , Urry C. Megan , Ghosh Aritra , Powell Meredith C. 
Published: February 2023

Abstract
The COSMOS field has been extensively observed by most major telescopes, including Chandra, HST, and Subaru. HST imaging boasts very high spatial resolution and is used extensively in morphological studies of distant galaxies. Subaru provides lower spatial resolution imaging than HST but a substantially wider field of view with greater sensitivity. Both telescopes provide near-infrared imaging of COSMOS. Successful morphological fitting of Subaru data would allow us to measure morphologies of over 104 known active galactic nucleus (AGN) hosts, accessible through Subaru wide-field surveys, currently not covered by HST. The morphological parameters indicate the types of galaxies that host AGNs. For 4016 AGNs between 0.03 < z < 6.5, we study the morphology of their galaxy hosts using GALFIT, fitting components representing the AGN and host galaxy simultaneously using the i-band imaging from both HST and Subaru. Comparing the fits for the differing telescope spatial resolutions and image signal-to-noise ratios, we identify parameter regimes for which there is strong disagreement between distributions of fitted parameters for HST and Subaru. In particular, the Sérsic index values strongly disagree between the two sets of data, including sources at lower redshifts. In contrast, the measured magnitude and radius parameters show reasonable agreement. Additionally, large variations in the Sérsic index have little effect on the

of each fit, whereas variations in other parameters have a more significant effect. These results indicate that the Sérsic index distributions of high-redshift galaxies that host AGNs imaged at ground-based spatial resolution are not reliable indicators of galaxy type and should be interpreted with caution.

Abstract
In the context of the ESO-VLT Multi-Instrument Kinematic Survey of Galactic globular clusters, here we present the line-of-sight velocity dispersion profile of NGC 6440, a massive globular cluster located in the Galactic bulge. By combining the data acquired with four different spectrographs, we obtained the radial velocity of a sample of ∼1800 individual stars distributed over the entire cluster extension, from ∼0.″1 to 778″ from the center. Using a properly selected sample of member stars with the most reliable radial velocity measures, we derived the velocity dispersion profile up to 250″ from the center. The profile is well described by the same King model that best fits the projected star density distribution, with a constant inner plateau (at σ
0 ∼ 12 km s−1) and no evidence of a central cusp or other significant deviations. Our data allowed us to study the presence of rotation only in the innermost regions of the cluster (r < 5″), revealing a well-defined pattern of ordered rotation with a position angle of the rotation axis of ∼132° ± 2° and an amplitude of ∼3 km s−1 (corresponding to V
rot/σ
0 ∼ 0.3). In addition, a flattening of the system qualitatively consistent with the rotation signal has been detected in the central region.
Delayed Development of Cool Plasmas in X-Ray Flares from the Young Sun-like Star κ
1 Ceti

Published: February 2023

Abstract
The Neutron star Interior Composition Explorer (NICER) X-ray observatory observed two powerful X-ray flares equivalent to superflares from the nearby young solar-like star κ
1 Ceti in 2019. NICER follows each flare from the onset through the early decay, collecting over 30 counts s−1 near the peak, enabling a detailed spectral variation study of the flare rise. The flare in September varies quickly in ∼800 s, while the flare in December has a few times longer timescale. In both flares, the hard-band (2–4 keV) light curves show typical stellar X-ray flare variations with a rapid rise and slow decay, while the soft X-ray light curves, especially of the September flare, have prolonged flat peaks. The time-resolved spectra require two temperature plasma components at kT ∼0.3–1 and ∼2–4 keV. Both components vary similarly, but the cool component lags by ∼200 s with a four to six times smaller emission measure (EM) compared to the hot component. A comparison with hydrodynamic flare loop simulations indicates that the cool component originates from X-ray plasma near the magnetic loop footpoints that mainly cools via thermal conduction. The time lag represents the travel time of the evaporated gas through the entire flare loop. The cool component has a several times smaller EM than its simulated counterpart, suggesting a suppression of conductive cooling, possibly by the expansion of the loop cross-sectional area or turbulent fluctuations. The cool component’s time lag and EM ratio provide important constraints on the flare loop geometry.
NICER/NuSTAR Characterization of 4U 1957+11: A Near Maximally Spinning Black Hole Potentially in the Mass Gap

Published: February 2023

Abstract
4U 1957+11 is a black hole candidate system that has been in a soft X-ray spectral state since its discovery. We present analyses of recent joint NICER and NuSTAR spectra, which are extremely well described by a highly inclined disk accreting into a near maximally spinning black hole. Owing to the broad X-ray coverage of NuSTAR, the fitted spin and inclination are strongly constrained for our hypothesized disk models. The faintest spectra are observed out to 20 keV, even though their hard tail components are almost absent when described with a simple corona. The hard tail increases with luminosity, but shows clear two-track behavior with one track having appreciably stronger tails. The disk spectrum color-correction factor is anticorrelated with the strength of the hard tail (e.g., as measured by the Compton y parameter). Although the spin and inclination parameters are strongly constrained for our chosen model, the mass and distance are degenerate parameters. We use our spectral fits, along with a theoretical prior on color-correction, an observational prior on likely fractional Eddington luminosity, and an observational prior on distance obtained from Gaia studies, to present mass and distance contours for this system. The most likely parameters, given our presumed disk model, suggest a 4.6 M
⊙ black hole at 7.8 kpc observed at luminosities ranging from ≈1.7% to 9% of Eddington. This would place 4U 1957+11 as one of the few actively accreting sources within the mass gap of ≈2–5 M
⊙ where there are few known massive neutron stars or low-mass black holes. Higher mass and distance, however, remain viable.
The Chromosphere Underneath a Coronal Bright Point

Published: February 2023

Abstract
Coronal bright points (CBPs) are sets of small-scale coronal loops, connecting opposite magnetic polarities, primarily characterized by their enhanced extreme-ultraviolet (EUV) and X-ray emission. Being ubiquitous, they are thought to play an important role in heating the solar corona. We aim at characterizing the barely explored chromosphere underneath CBPs, focusing on the related spicular activity and on the effects of small-scale magnetic flux emergence on CBPs. We used high-resolution observations of a CBP in Hβ and Fe i 617.3 nm from the Swedish 1 m Solar Telescope in coordination with the Solar Dynamics Observatory. This work presents the first high-resolution observation of spicules imaged in Hβ. The spicules were automatically detected using advanced image processing techniques, which were applied to the Dopplergrams derived from Hβ. Here we report their abundant occurrence close to the CBP “footpoints” and find that the orientation of such spicules is aligned along the EUV loops, indicating that they constitute a fundamental part of the whole CBP magnetic structure. Spatiotemporal analysis across multiple channels indicates that there are coronal propagating disturbances associated with the studied spicules, producing transient EUV intensity variations of the individual CBP loops. Two small-scale flux emergence episodes appearing below the CBP were analyzed, one of them leading to quiet-Sun Ellerman bombs and enhancing the nearby spicular activity. This paper presents unique evidence of the tight coupling between the lower and upper atmosphere of a CBP, thus helping to unravel the dynamic phenomena underneath CBPs and their impact on the latter.

. The EHT image of Sgr A* is consistent with a Kerr black hole’s expected appearance, and the results directly prove the existence of a supermassive black hole at the center of the Milky Way. Here, we use the EHT observational results for Sgr A* to investigate the constraints on its charge with the aid of Kerr-like black holes, paying attention to three leading rotating models, namely Kerr–Newman, Horndeski, and hairy black holes. Modeling the supermassive black hole Sgr A* as these Kerr-like black holes, we observe that the EHT results for Sgr A* place stricter upper limits on the parameter space of Kerr–Newman and Horndeski black holes than those placed by the EHT results for M87*. A systematic bias analysis reveals that observational results from future EHT experiments will place more precise limits on the charge of the black hole Sgr A*. Thus, the Kerr-like black holes and Kerr black holes are indiscernible in a substantial region of the EHT-constrained parameter space; the claim is substantiated by our bias analysis.
Quantification of the Writhe Number of the Evolution of Solar Filament Axes
Authors: Zhou 周 Zhenjun 振军 , Jiang Chaowei , Song Hongqiang , Wang Yuming , Hao Yongqiang , Cui Jun 
Published: February 2023

Abstract
Solar filament eruptions often show complex and dramatic geometric deformation that is highly relevant to the underlying physical mechanism triggering the eruptions. It is well known that the writhe of filament axes is a key parameter characterizing its global geometric deformation, but a quantitative investigation of the development of writhe during its eruption is still lacking. Here we introduce the Writhe Application Toolkit, which can be used to characterize accurately the topology of filament axes. This characterization is achieved based on the reconstruction and writhe number computation of three-dimensional paths of the filament axes from dual-perspective observations. We apply this toolkit to four dextral filaments located in the northern hemisphere with a counterclockwise (CCW) rotation during their eruptions. Initially, all these filaments possess a small writhe number (≤0.20) indicating a weak helical deformation of the axes. As the CCW rotation kicks in, their writhe numbers begin to decrease and reach large negative values. Combined with the extended Călugăreanu theorem, the absolute value of twist is deduced to decrease during the rotation. Such a quantitative analysis strongly indicates a consequence of the conversion of twist into writhe for the studied events.
L’articulation du récit idéologique et de l’éditorial dans l’introduction de La Cité libre de Walter Lippmann
Authors: Guilbert Thierry 
Published: February 2023

Cette approche inédite de Walter Lippmann prend en compte l’essayiste et l’éditorialiste dans leur matérialité discursive. Elle conçoit l’introduction de La Cité libre comme un discours en relation interdiscursive avec ses pairs et les préoccupations politiques de son époque, mais aussi et surtout comme un discours efficient qui mêle les procédés discursifs et persuasifs de l’éditorial avec le « récit idéologique » (Faye 2003). L’examen de ces traits montre comment se constitue la « narration primitive » ( ibid. ), préalable nécessaire à l’acceptabilité du « nouveau libéralisme ».
Des « modèles de développement » aux « mondes du développement » : une enquête statistique
Authors: Combarnous François , Piveteau Alain , Rougier Éric 
Published: February 2023

Cet article confronte les modèles prescriptifs du développement, tels que tirés de l’analyse génétique de huit décennies de conseils ou d’injonctions légitimées par la théorie économique dominante à chaque période, aux « mondes du développement » observés à la fin des années 2010. En projetant les pays en développement dans la galaxie de ces différents modèles, nous montrons que si plusieurs mondes sont parvenus à atteindre certaines cibles (soutenabilité sociale ou institution du marché), aucun monde n’est aujourd’hui réellement équipé pour s’orienter dans le monde commun que dessine le nouveau régime climatique et la question environnementale.

Des produits de base aux ressources : l’évolution de la place des matières premières dans les analyses et stratégies de développement
Authors: Géronimi Vincent , Mainguy Claire 
Published: February 2023

À partir des articles de la revue Mondes en développement , nous proposons une lecture, de l’évolution de la place des matières premières dans les analyses et stratégies du développement en fonction de trois principales dynamiques enchevêtrées : celle de l’évolution générale de la pensée du développement, selon la chronologie présentée par Hugon (2007) ; celle de l’évolution des marchés des matières premières, avec leurs chocs et leurs ruptures ; celle de la montée en puissance du développement durable. Se dessinent ainsi les contours d’une économie politique du développement, prenant en compte l’incertitude et les institutions, les stratégies des acteurs et les effets d’échelles.

Le peuple de Dieu, avis de recherche ou réalité à honorer ?
Authors: Pelletier Anne-Marie 
Published: February 2023

Il existe bien, dans le concret de la vie de l’Église, un « peuple de Dieu » actif et engagé, évoqué ici même par Dominique Greiner. En revanche, notre ecclésiologie, malgré Vatican II, continue à placer ce peuple de Dieu en retrait du sacerdoce ministériel. Il faut donc remonter la pente de la sacerdotalisation de l’Église institutionnelle, retrouver la théologie paulinienne de l’Église corps du Christ , où tous sont engendrés de la grâce baptismale pour constituer une Église communion . C’est dans ce cadre qu’il faut repenser aujourd’hui une théologie des ministères non cléricale et un sain exercice de l’autorité, qui honore en particulier la fraternité, ce bien essentiel mis en valeur par la première Église.
1 and 2 Chronicles as a discourse of power
Authors: Geyser-Fouche Ananda 
Published: February 2023

This article reflected a comparison of 1 and 2 Chronicles with its source documents. It transpires that the history of Israel and Judah is selectively retold by the authors of Chronicles with deliberate omissions and additions reflecting a certain emphasis. While the northern kingdom is negatively portrayed, the southern kingdom is positively evaluated. David is idealised as the perfect king. He is credited with founding the religious cult, which is contradicting the view in Exodus. The Jerusalem temple cult is legitimised and asserted as representing the only accurate religion. Chronicles 1 and 2 secured the temple elite’s position by legitimising their actions, functioning in this community as a discourse of power for as long as the (second) temple existed. Being a discourse of power, it set margins and excluded various groups usually considered part of the people of YHWH. The destruction of the (second) temple led to the disempowerment of this text, opening the way for it to be included in the Hebrew canon. The key insights of this article were that 1 and 2 Chronicles were used as a discourse of power, but the power block was lifted once the second temple was destroyed.Contribution: This article fitted into the scope of the journal by using historical-critical methods but also concepts from poststructuralism, namely the concept of powers behind texts and in language.
Cerebral faith and faith in praxis in the churches of European origin: The Presbyterian Church of South(ern) Africa
Authors: Duncan Graham A. 
Published: February 2023

This article investigated the paradox between church response to apartheid and resulting action at the local level in the South African churches of European origin from the perspective of the Presbyterian Church of South(ern) Africa (PCSA). It indicated that this discrepancy arose between the reflections (cerebral faith) at the highest levels of church councils, which operated in an intermittent manner and at a distance, compared with the responses (praxis as faith in action) of local church members who lived at the coalface of the struggle and sought to witness in a society dominated by racism, where the tension between faith and politics was most evident. The primary focus was on two inter-racial congregations, one of the PCSA, the other a united congregation in which the PCSA participated. This study used primary and secondary sources. The theoretical framework of the article was Thomas Groome’s approach of shared praxis.Contribution: This article contributed to the history of the apartheid era in ecclesiastical contexts. It demonstrated the anomalies that arose within different constituencies within churches of European origin by investigating the situation in one particular denomination. This was a discussion of the relationship of faith and politics in the private and public domains, which takes account of developments within a shared praxis approach.
