description: Σκοπός της παρούσας μελέτης ήταν να ερευνήσει τη σχέση μεταξύ της αντιλαμβανόμενης επιθετικής συμπεριφοράς με το επικοινωνιακό στυλ των καθηγητών και την ευχαρίστηση των μαθητών στο μάθημα της φυσικής αγωγής, αφού προηγουμένως τροποποιήθηκε για τον ελληνικό πληθυσμό το ερωτηματολόγιο του επικοινωνιακού στυλ. Το δείγμα αποτέλεσαν 261 αγόρια και κορίτσια από γυμνάσια του νομού Τρικάλων ηλικίας 13-15 ετών. Τα αποτελέσματα υποστήριξαν την εσωτερική συνοχή των μεταφρασμένων ερωτηματολογίων. Συνολικά, τα αποτελέσματα παρείχαν ικανοποιητική υποστήριξη για τις ψυχομετρικές ιδιότητες της κλίμακας του επικοινωνιακού στυλ τροποποιημένο στον ελληνικό πληθυσμό. Συνοπτικά, βρέθηκε μια αρνητική σχέση μεταξύ της λεκτικής επιθετικότητας του καθηγητή και της υπευθυνότητας καθώς επίσης και μεταξύ της λεκτικής επιθετικότητας του καθηγητή και της ευχαρίστησης των μαθητών. Βρέθηκε, επίσης, μια θετική σχέση της λεκτικής επιθετικότητας του καθηγητή με την κατηγορηματικότητα και μια θετική σχέση μεταξύ της υπευθυνότητας του καθηγητή και της ευχαρίστησης των μαθητών.
description: The purpose of this study was to examine the relationship between instructors’ verbal aggressiveness and socio-communicative style with students’ satisfaction in physical education. Firstly, the scale was translated based on responses of 261 greek high school students of Prefecture of Trikala. The results supported the internal consistency, and factor structure, of the translated instruments. Secondly, a correlation analysis conducted and the results showed a significant negative relationship between instructor’s verbal aggressiveness and responsiveness and also between instructor’s verbal aggressiveness and students’ satisfaction. It was also revealed a significant positive relationship between instructor’s verbal aggressiveness and responsiveness and students’ satisfaction.

description: For any integer s >= 0, we derive a combinatorial interpretation for the family of sequences generated by the recursion (parameterized by s) h_s(n) = h_s(n - s - h_s(n - 1)) + h_s(n - 2 - s - h_s(n - 3)), n > s + 3, with the initial conditions h_s(1) = h_s(2) = ... = h_s(s+2) = 1 and h_s(s+3) = 2. We show how these sequences count the number of leaves of a certain infinite tree structure. Using this interpretation we prove that h_s sequences are "slowly growing", that is, h_s sequences are monotone nondecreasing, with successive terms increasing by 0 or 1, so each sequence hits every positive integer. Further, for fixed s the sequence h_s(n) hits every positive integer twice except for powers of 2, all of which are hit s+2 times. Our combinatorial interpretation provides a simple approach for deriving the ordinary generating functions for these sequences.

Chemical studies of Pacific Ocean sponges
Creators: name: Coleman, John Edward
Publisher: name: University of British Columbia
Year: 2009

description: An investigation into the chemistry of two species of marine sponges has led to the isolation of eighteen new and twelve previously known secondary metabolites. The structures of the new compounds were elucidated by a combination of spectroscopic analysis and chemical degradation. A study of the organic extracts of a pink sponge collected of the coast of British Columbia led to the identification of botanones A to C (55-57), botanicol (58), cadlinolide C methyl acetal (59), and cadlinoglycine (60). Botanones A to C (55-57) were the first examples of diterpenoids with the degraded "labdane" skeleton to be isolated from a marine sponge. Cadlinoglycine (59) and cadlinolide C methyl acetal (60) and were both thought to be isolation artifacts. The novel secondary metabolites isolated from the pink sponge were useful in identifying the sponge as a previously undescribed Aplysilla species. The novel cyclic depsipeptides geodiamolides H to N (89-95) and P (97), as well as the known cytotoxins geodiamolides A to G (77-83), were isolated during the bioassay guided fractionation of the cytotoxic extracts of the marine sponge Cymbastela sp. Geodiamolides J to N (91-95) and P (97) represented the first examples in the geodiamolide family in which a serine residue had been incorporated. Extracts of Cymbastela sp. also yielded the novel cytotoxic peptides hemiasterlin A (98), hemiasterlin B (99), criamide A (100), and criamide B (101), in addition to the known peptide hemiasterlin (86). Chemical degradation, followed by Marfey's amino acid analysis of hemiasterlin (86), combined with single crystal X-ray diffraction analysis of hemiasterlin methyl ester (141), established the absolute configuration of 86. Using a combination of chemical degradation and C D analysis, the absolute configurations of hemiasterlin A (98) and hemiasterlin B (99) were also determined. The hemiasterlins were shown to be potently cytotoxic in vitro against several cell lines, and hemiasterlin (86) demonstrated promising activity in vivo against murine leukemia P388 in mice. Studies on the mechanism of activity of hemiasterlin A (98) suggested that it exerted its cytotoxic affects by inhibiting spindle microtubule dynamics. Both hemiasterlin (86) and hemiasterlin A (98) were more potent cytotoxins and mitotic blockers than the known microtubule inhibitors paclitaxel (113) and vinblastine (114). The total synthesis of hemiasterlin (86) was accomplished. Using the methodology developed in the total synthesis, several analogs were synthesized in the beginning of an extensive structure activity study. [Molecular Structures]

description: Goal modelling aims to capture stakeholder and system goals, together with social, intentional, and structural relationships, in a way that supports trade-off analysis and decision making. Goal models and business process models provide complementary and synergetic views of a system, which lead to a more complete understanding of what exists and a better description of what needs to be designed than with only one of these views. The User Requirements Notation (URN), standardized in 2008 by the International Telecommunication Union (ITU-T) with improved versions in 2012 and 2018, combines goal modelling with process modelling, while providing graphical and textual syntaxes for both views. URN helps modellers exploit the value of social modelling in the context of process design and improvement. In this paper, we report on nearly two decades of combined goal/process modelling with URN in different areas -- based on coarse-grained statistics from a literature review and the authors' personal experiences with URN. In particular, beyond the telecommunication services for which URN was created, we highlight applications to goal/process alignments, regulatory compliance and intelligence, process adaptation and improvement, value co-creation and service systems, and goal-oriented process mining, as well as several advanced modelling techniques. An overview of the tool-supported analyses (for satisfaction, alignment, compliance, and others) and model creation mechanisms (composition, aspects, slicing, adaptation, reuse, and others) is also provided. The last part of this paper focuses on important challenges and exciting opportunities for future research, especially in the areas of data-driven applications (e.g, AI/machine learning), socio-cyber-physical systems, and usable automation.

description: The aspect more often met in the education of the mentally retarded, is related with the improvement of cognitive abilities, the focus in the curriculum which is identical for all students and the accomplishment of goals. The need that occurs from the social dimension of mental retardation, brings an aspect which is related with the development of social abilities of students, as to enhance their autonomy, and cope with the stigma as to improve their quality of life.This study aims to discuss from five special educators narrations’ how they see their role and how they interpret this role in their everyday practices concerning the two aspects in education. Analysis of narrations revealed some basic themes and the profile of teachers, which show a picture of their attitude about the themes that were explored.

description: Although the theoretical study of very low metallicity (Z) and metal-free stars is not new, their importance has recently greatly increased since two related fields have been developing rapidly. The first is cosmological simulations of the formation of the first stars and of the reionisation period. The second is the observations of extremely metal poor stars. In this paper, we present pre-supernova evolution models of massive rotating stars at very low Z (Z=1e-8) and at Z=0. Rotation has a strong impact on mass loss and nucleosynthesis. Models reaching break-up velocities lose up to ten percents of their initial mass. In very low Z models, rotational and convective mixing enhances significantly the surface content in carbon, nitrogen and oxygen (CNO) when the star becomes a red supergiant. This induces a strong mass loss for stars more massive than about 60 solar masses. Our models predict type Ib,c supernovae and gamma-ray bursts at very low Z. Rotational mixing also induces a large production of CNO elements, in particular of primary nitrogen. The stellar wind chemical composition is compatible with the most metal-poor star know to date, HE 1327-2326, for CNO elements. Our models reproduce the early evolution of nitrogen in the Milky Way.

Superorbital Modulation in the High-Mass X-ray Binary 4U 1538-52, and Possible Modulation in IGR J16393-4643

description: Hard X-ray observations with the Neil Gehrels Swift Observatory Burst Alert Telescope (BAT) reveal superorbital modulation in the wind-accreting supergiant high-mass X-ray binary (HMXB) 4U 1538-52 at a period of 14.9130 +/- 0.0026 days that is consistent with four times the 3.73 day orbital period. These periods agree with a previously suggested correlation between superorbital and orbital periods in similar HMXBs. During the ~14 years of observations the superorbital modulation changes amplitude, and since ~MJD 57,650 it was no longer detected in the power spectrum, although a peak near the second harmonic of this was present for some time. Measurements of the spin period of the neutron star in the system with the Fermi Gamma-ray Burst Monitor show a long-term spin-down trend which halted towards the end of the light curve, suggesting a connection between dP(spin)/dt and superorbital modulation, as proposed for 2S 0114+650. However, an earlier torque reversal from INTEGRAL observations was not associated with superorbital modulation changes. B and V band photometry from the Las Cumbres Observatory reveals orbital ellipsoidal photometric variability, but no superorbital optical modulation. However the photometry was obtained when the 14.9130 day period was no longer detected in the BAT power spectrum. We revisit possible superorbital modulation in BAT observations of IGR J16393-4643 but cannot conclusively determine whether this is present, although is not persistent. We consider superorbital modulation mechanisms, and suggest that the Corotating Interaction Region model, with small deviations from orbital synchronization, appears promising.

Στην παρούσα ποιοτική έρευνα αναλύεται ο λόγος των Προέδρων δύο ελληνικών Συλλόγων Γονέων και Κηδεμόνων στο Βερολίνο, που αποτελούν «πρόσωπα-κλειδιά». Μέσα από την ανάλυση λόγου επιχειρείται μια διεισδυτική ματιά στις συνθήκες του ιδιαίτερου πλαισίου που τους περιβάλλει και τους επιβάλλεται. Σε διάφορα ερωτήματα –όπως ‘αν, πώς και πόσα ελληνικά χρειάζεται να παρακολουθήσουν τα παιδιά σχολικής ηλικίας’, οι απαντήσεις είναι συχνά αντικρουόμενες και οι ομιλητές μοιάζει να αυτοαναιρούνται. Επιχειρείται μια πολύπλευρη αποτύπωση του ευαίσθητου αυτού ζητήματος, καθώς αναφέρονται π.χ. στα κριτήρια των αποφάσεών τους, καταθέτουν την κριτική τους, περιγράφουν τα προβλήματα και εμπόδια που αντιμετωπίζουν. Διαφαίνεται το πόσο ενημερωμένοι είναι για την προσφορά των διαφόρων προγραμμάτων ελληνομάθειας, τι προσδοκούν από μια ‘ελληνική παιδεία’ και πώς την αντιλαμβάνονται οι ίδιοι, ποιες οι ελπίδες ή/και οι απαιτήσεις τους από εκπαιδευτικούς, σχολεία, φορείς της ελληνομάθειας και πολλά ακόμη συναφή ερωτήματα.
description: The Greek language teaching to the Greek students of our country raises a dilemma which has to be faced by the Greek families living in Germany during their children’s school life. This qualitative research presents the speech of the Presidents of the two Greek Parents’ Associations in Berlin. Through the analysis of the speech a thorough look into the special social conditions is attempted. The various questions concerning the necessity of the Greek language lessons, the methods and the desired level that the students are expected to acquire usually have contradictable answers and also the speakers seem to contradict themselves. This research attempts to show the multiple sides of this sensitive issue as it refers for example to the criteria of their decisions, it presents their critiques and it describes the problems and the obstacles they face. Moreover, it shows how well informed they really are about the availability of the various Greek learning programs, what they expect from a ‘Greek education’ and how they perceive it themselves, what their expectations or/and their requirements are from the teachers, the schools and the institutions of the Greek language learning as well as many more relevant issues.

description: This study concentrates on the presentation of the basic characteristics of the greek law 3389/2005, which introduced the public-private partnerships in greek society.In the introduction of the study, the major advantages of the new legislation are presented, while in its main body, the study elaborates on specific issues, such as the private financial initiative, the jurisdiction, as well as the role of the state in this kind of partnerships.Moreover, there is an extensive reference to the legislation that regulates the concession contracts, which are quite similar to the public-private partnerships.For this reason a distinction between them is attempted, so that their differences, as well as their resemblances are illustrated clearly to the reader.After the presentation of both forms of cooperation between the public and private sector, the study ends up with some important conclusions, demonstrating the way in which they are related and how they can be distinguished, so that the best way of cooperation is selected each time, in order to fulfill the goal of public procurement.

On the Eddington limit in accretion discs

Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Although the Eddington limit has originally been derived for stars, recently its relevance for the evolution of accretion discs has been realized. We discuss the question whether the classical Eddington limit - which has been applied globally for almost all calculations on accretion discs - is a good approximation if applied locally in the disc. For this purpose, a critical accretion rate corresponding to this type of modified classical Eddington limit is calculated from thin alpha-disc models and slim disc models. We account for the non-spherical symmetry of the disc models by computing the local upper limits on the accretion rate from vertical and radial force equilibria separately. It is shown that the results can differ considerably from the classical (global) value: The vertical radiation force limits the maximum accretion rate in the inner disc region to much less than the classical Eddington value in thin alpha-discs, while it allows for significantly higher accretion rates in slim discs. We discuss the implications of these results for the evolution of accretion discs and their central objects.

description: We evaluate the thermal torques exerted on low-mass planets embedded in gaseous protoplanetary discs with thermal diffusion, by means of high-resolution three-dimensional hydrodynamics simulations. We confirm that thermal torques essentially depend on the offset between the planet and its corotation, and find a good agreement with analytic estimates when this offset is small compared to the size of the thermal disturbance. For larger offsets that may be attained in discs with a large pressure gradient or a small thermal diffusivity, thermal torques tend toward an asymptotic value broadly compatible with results from a dynamical friction calculation in an unsheared medium. We perform a convergence study and find that the thermal disturbance must be resolved over typically 10 zones for a decent agreement with analytic predictions. We find that the luminosity at which the net thermal torque changes sign matches that predicted by linear theory within a few percents. Our study confirms that thermal torques usually supersede Lindblad and corotation torques by almost an order of magnitude for low mass planets. As we increase the planetary mass, we find that the ratio of thermal torques to Lindblad and corotation torques is progressively reduced, and that the thermal disturbance is increasingly distorted by the horseshoe flow. Overall, we find that thermal torques are dominant for masses up to an order of magnitude larger than implemented in recent models of planetary population synthesis. We finally briefly discuss the case of stellar or intermediate-mass objects embedded in discs around AGNs.

description: In the present paper, we consider nonresonant corrections to $ 2s-ns/nd $ transition frequencies in hydrogen for the experiments based on two-photon spectroscopy. A detailed study of angular correlations of quantum interference effects within the framework of rigorous quantum electrodynamics is given. Closed expressions for the resonant two-photon scattering cross sections on an atomic level with dependence on all atomic quantum numbers including fine and hyperfine structure are derived. These expressions are applied for the description of experiments based on two-photon spectroscopy with fixing of incident (outgoing) photon polarizations. We demonstrate that for certain experimental geometry nonresonant corrections could be significant for the determination of Rydberg constant and proton charge radius.

description: Reviewing the second instalment of Amy Lowell’s anthology series Some Imagist Poets in 1916, the Times Literary Supplement declared that ‘Imagist poetry fills us with hope; even if it is not very good in itself, it seems to promise a form in which very good poetry could be written.’ This study aims to dismantle this common assumption about Imagist verse. Although many commentaries have acknowledged Imagism’s far-reaching impact upon American poetry, few have treated its theoretical premises with the scepticism it deserves, traced the movement’s pedagogical legacy, or acknowledged the importance of contemporary poets who have challenged the pervasive influence of Pound’s Imagist tenets. In Chapter One, I discuss the privileging of the image in modern poetry and criticism from the original Imagistes to Robert Bly’s mid-century ‘Deep Imagism’. Chapter Two explores the critical tendency to misread William Carlos Williams as a poet of the concrete image, before exposing the tangible effects of this skewed reading in the verse of his disciple Denise Levertov. Chapters Three to Six are made up of author studies, analysing the poetry of Charles Simic, C.K. Williams, Louise Glück, and Robert Hass, to illuminate the various aesthetic strategies by which they challenged Imagism’s authoritarian precepts. In Chapter Seven, I discuss Rae Armantrout’s Money Shot (2010) and Timothy Donnelly’s The Cloud Corporation (2010) as critiques of the Imagist emphasis on ‘the part rather than the whole,’ while in the final chapter, I analyse Ocean Vuong’s debut Night Sky With Exit Wounds (2016) as evidence of the survival of the Imagist hegemony into contemporary practice.

Metal speciation and characterization of copper complexing ligands in seawater using electrospray ionization mass spectrometry

description: Electrospray ionization mass spectrometry (ESI-MS) provides information regarding the structure and distribution of dissolved polar and ionic metal species which cannot be obtained using electroanalytical or spectroscopic techniques. Such information is necessary if the role of metal complexes in biological and geochemical processes is to be fully understood. The utility of ESI-MS for metal speciation is evaluated using a range of well characterized organic ligands and biogeochemically important metal ions. The technique reveals the stoichiometry and metal oxidation state of organic and inorganic complexes and how speciation changes with solution pH. Results for Cu²⁺ and 8-hydroxyquinoline (HL) show for the first time that ESI-MS can determine the distribution of dissolved metal species at equilibrium. A detection limit of 13 nM for the complex Cu[sup II]L⁺ demonstrates the potential of this technique for studying metal species in natural waters. Ionization of uncharged complexes is achieved by protonation, deprotonation or electrochemical oxidation of the ligand. N,N-Diethyldithiocarbamate oxidation is confirmed by studies involving alkali and alkaline earth metals, which suggest that ESI-MS detection also depends on the polarity and thermodynamic stability of the complex. Metal complexation by large polyfunctional organic compounds is investigated using tannins as model natural ligands. Simultaneous detection of free and complexed tannins allows the effects of metal concentration, pH and ionic strength to be investigated. Determination of ligand structure and copper binding site by tandem mass spectrometry further illustrates the unique capabilities of this technique for metal speciation. ESI-MS is combined with immobilized metal-ion affinity chromatography (IMAC) to extract and characterize copper complexing ligands from British Columbia coastal waters. Initial UV analysis of IMAC extracts suggests that river and surface waters are significant sources of these ligands. Subsequent ESI-MS analysis requires matrix removal which is achieved on-line by flow injection analysis using a custom made XAD- 16 column. A copper ligand of molecular mass 259 is identified in the surface seawater extract with highest UV absorbance. The data are consistent with a dipeptide containing two primary amino groups, a result supported by studies in which IMAC is combined with other methods for characterizing copper ligands in seawater.

description: Core-collapse supernovae (CC-SNe) are the explosions that announce the death of massive stars. Some CC-SNe are linked to long-duration gamma-ray bursts (GRBs) and are highly aspherical. One important question is to what extent asphericity is common to all CC-SNe. Here we present late-time spectra for a number of CC-SNe from stripped-envelope stars, and use them to explore any asphericity generated in the inner part of the exploding star, near the site of collapse. A range of oxygen emission-line profiles is observed, including a high incidence of double-peaked profiles, a distinct signature of an aspherical explosion. Our results suggest that all CC-SNe from stripped-envelope stars are aspherical explosions and that SNe accompanied by GRBs exhibit the highest degree of asphericity.

description: Piezoelectric fluoropolymers convert mechanical energy to electricity and are ideal for sustainably providing power to electronic devices. To convert mechanical energy, a net polarization must be induced in the fluoropolymer, which is currently achieved via an energy intensive electrical poling process. Eliminating this process will enable the low-energy production of efficient energy harvesters. Here, by combining molecular dynamics simulations, piezoresponse force microscopy, and electrodynamic measurements, we reveal a hitherto unseen polarization locking phenomena of poly(vinylidene fluoride-$\mathit{co}$-trifluoroethylene) (PVDF-TrFE) perpendicular to the basal plane of two-dimensional (2D) Ti$_{3}$C$_{2}$T$_{\mathit{x}}$ MXene nanosheets. This polarization locking, driven by strong electrostatic interactions enabled exceptional energy harvesting performance, with a measured piezoelectric charge coefficient, $\mathit{d_{33}}$, of -52.0 picocoulombs per newton, significantly higher than electrically poled PVDF-TrFE (approximately -38 picocoulombs per newton). This study provides a new fundamental and low energy input mechanism of poling fluoropolymers, which enables new levels of performance in electromechanical technologies.

description: A complex filling of a CR manifold is said to be equivariant with respect to a CR action if the action extends to a smooth action by biholomorphisms on the whole filling. Under a noncompactness condition for the action, we describe all equivariant fillings of strongly pseudoconvex CR manifolds of dimension 3. Since the standard sphere is the only compact strongly pseudoconvex CR manifold whose automorphism group is not compact, we only have to study its fillings.

description: The string corrections of tree-level open-string amplitudes can be described by Selberg integrals satisfying a Knizhnik–Zamolodchikov (KZ) equation. This allows for a recursion of the α'-expansion of tree-level string corrections in the number of external states using the Drinfeld associator. While the feasibility of this recursion is well-known, we provide a mathematical description in terms of twisted de Rham theory and intersection numbers of twisted forms. In particular, this leads to purely combinatorial expressions for the matrix representation of the Lie algebra generators appearing in the KZ equation in terms of directed graphs. This, in turn, admits efficient algorithms for symbolic and numerical computations using adjacency matrices of directed graphs and is a crucial step towards analogous recursions and algorithms at higher genera.

description: Diversity in the exhibited behavior of a given system is a desirable characteristic in a variety of application contexts. Synthesis of conformant implementations often proceeds by discovering witnessing Skolem functions, which are traditionally deterministic. In this paper, we present a novel Skolem extraction algorithm to enable synthesis of witnesses with random behavior and demonstrate its applicability in the context of reactive systems. The synthesized solutions are guaranteed by design to meet the given specification,while exhibiting a high degree of diversity in their responses to external stimuli. Case studies demonstrate how our proposed frame-work unveils a novel application of synthesis in model-based fuzz testing to generate fuzzers of competitive performance to general-purpose alternatives, as well as the practical utility of synthesized controllers in robot motion planning problems.

description: Modern cognitive neuroscience has focused on mapping what information is processed both where and when in the brain as an initial step towards understanding howinformation is processed by the brain. Brain mapping is most commonly performed using the linear encoding model - a computational tool that can be used to align brain measurements with numerical stimulus representations that can be informative of the underlying neural processes. But as we move towards more naturalistic experimental settings and start to work with increasingly complex stimulus representations, it becomes important to test the boundaries of what we are able to learn using existing computational tools so we can adjust them accordingly. In this work, we examine two potential limitations of the linear encoding model. First, we look at a specific problem setting that shows that the existing framework does not always allow us to disentangle where specific stimulus-related information is processed in the brain. As an initial step towards addressing this issue, we propose a new framework that can be used to group together areas of the brain that are responsible for processing similar information. Second, we explore whether using a more expressive, nonlinear encoding model can allow us to better align the internal representational spaces of artificial neural networks, from which we can derive more complex and potentially more informative stimulus representations, with those of the brain. Overall, our proposed extensions to conventional encoding approaches can help neuroscientists unlock a richer and more complete space of brain mappings.

description: We compare the star forming main sequence (SFMS) -- both integrated and resolved on 1kpc scales -- between the high-resolution TNG50 simulation of IllustrisTNG and observations from the 3D-HST slitless spectroscopic survey at z~1. Contrasting integrated star formation rates (SFRs), we find that the slope and normalization of the star-forming main sequence in TNG50 are quantitatively consistent with values derived by fitting observations from 3D-HST with the Prospector Bayesian inference framework. The previous offsets of 0.2-1dex between observed and simulated main sequence normalizations are resolved when using the updated masses and SFRs from Prospector. The scatter is generically smaller in TNG50 than in 3D-HST for more massive galaxies with M_*>10^10Msun, even after accounting for observational uncertainties. When comparing resolved star formation, we also find good agreement between TNG50 and 3D-HST: average specific star formation rate (sSFR) radial profiles of galaxies at all masses and radii below, on, and above the SFMS are similar in both normalization and shape. Most noteworthy, massive galaxies with M_*>10^10.5Msun, which have fallen below the SFMS due to ongoing quenching, exhibit a clear central SFR suppression, in both TNG50 and 3D-HST. In TNG this inside-out quenching is due to the supermassive black hole (SMBH) feedback model operating at low accretion rates. In contrast, the original Illustris simulation, without this same physical SMBH mechanism, does not reproduce the central SFR profile suppression seen in data. The observed sSFR profiles provide support for the TNG quenching mechanism and how it affects gas on kiloparsec scales in the centers of galaxies.
