description: In this paper, we study the dynamics of cylindrical armoured bubbles excited by mechanical vibrations. A step by step transition from cylindrical to spherical shape is reported as the intensity of the vibration is increased, leading to a reduction of the bubble surface and a dissemination of the excess particles. We demonstrate through energy balance that nonspherical armoured bubbles constitute a metastable state. The vibration instills the activation energy necessary for the bubble to return to its least energetic stable state: a spherical armoured bubble. At this point, particle desorption can only be achieved through higher amplitude of excitation required to overcome capillary retention forces. Nonspherical armoured bubbles open perspectives for tailored localized particle dissemination with limited excitation power.
Article Processing Charges, Altmetrics and Citation Impact: Is there an economic rationale?

description: The present study aims to analyze 1) the relationship between Citation Normalized Score of scientific publications and Article Processing Charges (APCs) of Gold Open Access (OA) publications 2) the determinants of APCs. To do so, we used APCs information provided by the OpenAPC database, citation scores of publications from the WoS database and, for Altmetrics, data from Altmetrics.com database, over the period from 2006 to 2019 for 83,752 articles published in 4751 journals belonging to 267 distinct publishers. Results show that contrary to common belief, paying high APCs does not necessarily increase the impact of publications. First, large publishers with high impact are not the most expensive. Second, publishers with the highest APCs are not necessarily the best in terms of impact. Correlation between APCs and impact is moderate. Regarding the determinants, results indicate that APCs are on average 50% higher in hybrid journals than in full OA journals. The results also suggest that Altmetrics do not have a great impact: OA articles that have garnered the most attention on internet are articles with relatively low APCs. Another interesting result is that the ''number of readers'' indicator is more effective as it is more correlated with classic bibliometrics indicators than the Altmetrics score.

Death Speaks Russian: Heteroglossia and Dialogical Tonality in Musorgsky’s “Serenade” from Songs and Dances of Death

description: Composed in the mid 1870’s, Modest Musorgsky’s song cycle Songs and Dances of Death can be easily placed within the geographically and temporally situated cultural and sociopolitical context of the subject matter of dying that thematically unifies it. The article focuses on the set’s second song, [GA1] titled “Serenade,” seeking to investigate the structural conditions that afford its hermeneutic association with this context. To do so, it borrows its critical apparatus from Mikhail Bakhtin’s literary theory, and particularly the notions of heteroglossia and dialogism, intersected with the concept of markedness, as it has been appropriated to musicology from structural linguistics by Robert Hatten. The analysis demonstrates the song’s heteroglot disposition, evinced by the stylistic opposition of its two comprising sections, the first unmarked and the second marked by readily identifiable tokens of Russianness. In particular, it concentrates on the song’s tonal duality, re-conceptualizing it in terms of what per Bakhtin could be described as dialogical tonality. In this respect, the tonal ambiguity of the song’s harmonic macro-structure is mapped onto the simultaneous yet incommensurable perspectives that define its poetic narrative, allowing for the interpretation of the song’s cultural import as an attempt at aestheticizing the ambivalent liminality of the act of dying. Not a completely necessary correction. “Entitled” is a little bit outdated.

description: If observed, charged lepton flavour violation is a clear sign of new physics - beyond the Standard Model minimally extended to accommodate neutrino oscillation data. We briefly review several extensions of the Standard Model which could potentially give rise to observable signals, also emphasising the rôle of charged lepton flavour violation in probing such new physics models.

(B) Peptide sequences that are associated with BMI. (C) Sequence motifs in peptide probes associated with BMI. Probes associated with BMI typically have N-terminus glutamic acid (N-glutamic acid). Motif information content (bits, y-axis) is shown for each position (x-axis). (D) The N-terminus di-serine and glutamic acid motifs are present in nearly all age- and BMI-associated probes, respectively, whereas these motifs are much less common across non-age and non-BMI associated probes. Fraction of probes (y-axis) with specified motifs (color legend) are shown for age, BMI, and all other probes (x-axis). (E) The presence of N-terminus glutamic acid (E) residues is associated with BMI-correlated probes. A single E residue is comparable in significance to multiple E residues. The presence of glutamic acid at the N-terminus is significantly associated with BMI, whereas any other position in the peptide probe has limited association with BMI. (F) The di-serine score is similar across array formats. Donor samples were assayed on standard sized arrays (131 k probes, x-axis) and large-format arrays (3366 k probes y-axis) to find that the presence of N-terminus di-serine motif conferred similar association with age (axis values). Each data point represents a single donor. (G) On the 3366 k array format with both acetyl capped and uncapped probes (351 k array format, see Methods), age-associated probes are N-terminus acetylated capped. Each data point shows probe count (y-axis) for a single cutoff value to consider a probe to be age associated (x-axis). (H) Donor samples were assayed on arrays with 100% acetylated probes (x-axis) and arrays where only a fraction of probes where acetylated (y-axis). Probes that are acetylated in the split array (red) had higher association with age than those probes uncapped on the split array (black). This intra-array experimental design controls for potential inter-array confounders. Each data point represents a single probe and axes are average values across donors of specified age groups.

Subjects: European art music; Greek crisis; cultural politics; cultural organizations; music ensembles; the National Opera of Greece.

description: European art music in Greece has been considered the imaginary musical ideotype that serves the creation of a distinctive cultural policy by retaining the role of “high art.” Greek organizations that deal with European art music have always had the opportunity to engage in the broader cultural arena and shape national, artistic, economic, local, and supra-local policies. Each one with their own diverse goals, trends, interests, and perspectives. For about 30 years, cultural and economic policy in Greece has been relatively stable. Nowadays, it has become evident that the field of European art music has significantly been transformed, since the social and economic crisis has led to radical changes, new directions and transformations of practices. In order to highlight some aspects of the political economy of European art music in Greece, I will provide specific examples that demonstrate, in brief, how the crisis affected Greek cultural organizations and the people associated with them, in terms of two perspectives: the economic-administrative and the cultural-artistic. Through both an ethnographic and a textual approach of a case study, I will critically examine various issues of identity, practice, and discourse that concern the multimodal relation between modern Greek and European music culture.

description: Charged Lepton Flavor Violation is expected to be one of the most powerful tools to reveal physics beyond the Standard Model. The COMET experiment aims to search for the neutrinoless coherent transition of a muon into an electron in the field of a nucleus. Muon-to-electron conversion has never been observed, and can be, and would be, clear evidence of new physics if discovered. The experimental sensitivity of this process, defined as the ratio of the muon-to-electron conversion rate to the total muon capture rate, is expected to be significantly improved by a factor of 100 to 10,000 in the coming decade. The COMET experiment will take place at J-PARC with single event sensitivities of the orders of $10^{-15}$ and $10^{-17}$ in Phase-I and Phase-II, respectively. The ambitious goal of the COMET experiment is achieved by realizing a high-quality pulsed beam and an unprecedentedly powerful muon source together with an excellent detector apparatus that can tolerate a severe radiation environment. The construction of a new beam line, superconducting magnets, detectors and electronics is in progress towards the forthcoming Phase-I experiment. We present the experimental methods, sensitivity and backgrounds along with recent status and prospects.

New Approaches in "Theory of Music" Courses: Preliminary Findings of a Pilot Study in Conservatory Settings

description: In our increasingly multimodal era, it is widely recognized that music educators ought to consider anew which ways are more effective for students to be engaged with music, what it means to teach music in a multimodal context, and what changes in pedagogy, curriculum, and methodologies are needed. Whereas traditional notions of music theory focus primarily on reading and writing music through standard notation and musical symbols, multimodal multi-sensory activities allow new types of music understanding and learning, leading to the formation of new types of music literacies. However, "Theory of Music" courses in Greece, as a part of the overall music conservatory curriculum being in-use for more than 60 years, are not consistent with the current philosophical trends in the field of music education. In this article, we argue that music teachers in "Theory of Music" classrooms can incorporate multimodal multisensory activities – aural, visual, tactile, and kinesthetic – in order to reinforce the perception of abstract musical concepts. Furthermore, preliminary findings of a pilot study in conservatory settings will be presented, as well as musical-educational activities development based on the multimodal and multi-sensory music teaching-learning approach.

Stacking Caustic Masses from Galaxy Clusters

description: Ongoing and future spectroscopic surveys will measure numerous galaxy redshifts within tens of thousands of galaxy clusters. However, the sampling within these clusters will be low, 15 < N < 50 per cluster. With such data, it will be difficult to achieve accurate and precise mass estimates for individual clusters using phase-space mass estimation techniques. We develop and test a new stacking algorithm based on the caustic technique, which reduces the mass scatter in for ensemble clusters from 70% for individual clusters to less than 10% for ensemble clusters with only 15 galaxies per cluster and 100 clusters per ensemble. With > 1000 galaxies per ensemble phase-space, the escape-velocity edge becomes readily identifiable and the presence of interloping galaxies is minimized. We develop and test an algorithm to trace the projected phase-space surface directly, which results in minimally biased dynamical mass estimates. We then quantify how binning and sampling affect the phase-space-based mass estimates when using an observational proxy that incorporates realistic mass scatter, like richness, and find the added uncertainty in the binning procedure has minimal influence on the resulting bias and scatter of the stacked mass estimates.

description: Multirelations provide a semantic domain for computing systems that involve two dual kinds of nondeterminism. This paper presents relational formalisations of Kleisli, Parikh and Peleg compositions and liftings of multirelations. These liftings are similar to those that arise in the Kleisli category of the powerset monad. We show that Kleisli composition of multirelations is associative, but need not have units. Parikh composition may neither be associative nor have units, but yields a category on the subclass of up-closed multirelations. Finally, Peleg composition has units, but need not be associative; a category is obtained when multirelations are union-closed.

Exploring the Function of the Female Lamenter in the Bereavement Process: A Case Study in Chios Island
Creators: name: Akoyunoglou, Mitsi
Publisher: name: Series Musicologica Balcanica
Year: 2020
Subjects: Greek lament, Chios Island, bereavement, death rituals, narrative approach.

description: Lamentation dates back to ancient Greece and has survived through the centuries primarily as an exclusive tradition of women. It can be described as a controlled performative act of memory and mourning that has been closely associated with all stages of the death rituals. Nowadays it is a ritual performed in just a handful of Greek villages. The present study focuses on a 91-year-old female lamenter from Mesta, a village in Chios Island. The function of her role as a female lamenter in the bereavement process of self and others is examined through biographical narrative interviews. Biographical narrative analysis, as a tool to explore and gain insight about a human experience, allows for a closer investigation of the lamentation experience; it does so by reaching back in time through establishing a narrative connection to the role of the lamenter and interpreting her function within the bereavement process of self and others. Following a thematic analysis of the narration, it appears that the lamenter, through the semi-structured and semi-improvised moiroloi, becomes the bridge between the living and the dead, communicates the pain, expresses the inner tension and, as a result, may facilitate the mourner to reach catharsis.

description: We present a detailed theoretical study of the electronic, magnetic, and structural properties of magnesiowüstite Fe$_{1-x}$Mg$_x$O with $x$ in the range between 0$-$0.875 using a fully charge self-consistent implementation of the density functional theory plus dynamical mean-field theory (DFT+DMFT) method. In particular, we compute the electronic structure and phase stability of the rock-salt B1-structured (Fe,Mg)O at high pressures relevant for the Earth's lower mantle. We obtain that upon compression paramagnetic (Fe,Mg)O exhibits a spin-state transition of Fe$^{2+}$ ions from a high-spin to low-spin (HS-LS) state which is accompanied by a collapse of local magnetic moments. The HS-LS transition results in a substantial drop of the lattice volume by about 4$-$8 %, implying a complex interplay between electronic and lattice degrees of freedom. Our results reveal a strong sensitivity of the calculated transition pressure $P_{\rm tr.}$ upon addition of Mg. While for Fe-rich magnesiowüstite, Mg $x < 0.5$, $P_{\rm tr.}$ exhibits a rather weak variation at $\sim$80 GPa, for Fe-poor (Fe,Mg)O it drops, e.g., by about 35 % to 52 GPa for Mg $x=0.75$. This behavior is accompanied by a substantial change of the spin transition range from 50$-$140 GPa in FeO to 30$-$90 GPa for $x=0.75$. In addition, the calculated bulk modulus (in the HS state) is found to increase by $\sim$12 % from 142 GPa in FeO to 159 GPa in (Fe,Mg)O with Mg $x=0.875$. We find that the pressure-induced HS-LS transition has different consequences for the electronic properties of the Fe-rich and poor (Fe,Mg)O. For the Fe-rich (Fe,Mg)O, the transition is found to be accompanied by a Mott insulator to (semi-) metal phase transition. In contrast to that, for $x>0.25$, (Fe,Mg)O remains insulating up to the highest studied pressures, implying a Mott insulator to band insulator phase transition at the HS-LS transformation.

description: This paper discusses some of the organological details of the auloi and its playing techniques and gestures as depicted mostly via ancient imagery. When approaching any aspect of real musical practice, we have to decode very carefully the painter’s effort to render the performance of music, including technical details; awareness of the peculiarities, conventions and restrictions of the material, especially in vase paintings, must be taken into account. Still, representations of music making, especially on Attic vase paintings of the late archaic and classical period, must have been related in some way to the actual playing of music and thus reflect a recognizable ‘reality’. I will raise awareness of the issues emerging when reading these images, in order to help us gain a better understanding of aulos music during this period.

Subjects: Historical ethnomusicology, microhistory, satire, 19th century, Ottoman Empire.

description: Conducting fieldwork in the ethnomusicological past, among other things may consist of coping with a wide variety of textual records, such as newspapers, magazines, public or private archives and so on. Especially, as far as newspapers and magazines of any kind are concerned, historical awareness is of great importance, for instance when the understanding of the relevant political and cultural mentalité of the writers, is a critical determinant of one’s ability to fully comprehend and make use of the possible findings, or -sometimes- even the lack of them. Quite often, the hardest part is when trying to “decrypt”, analyze and reconstruct the narration of a person whose Self emerges only through his corresponding writings. This is the case with Jonah (aka Konstantínos Aravantinós), writer of the satirical calendar of Ioannina, Karavida, during 1873-1874. Following the above paradigm, it is evident that a historical ethnomusicological research of this kind has to deal with a two-fold methodological challenge: thoroughly creating a virtual historical space in which specially customized text analysis skills can provide the ability to reach out closer to voices and sounds of the past. The latter, is a problematic leading to research theories and methodologies offered by relevant scientific fields.

description: We analyze the modular properties of D3-brane instanton corrections to the hypermultiplet moduli space in type IIB string theory compactified on a Calabi-Yau threefold. In Part I, we found a necessary condition for the existence of an isometric action of S-duality on this moduli space: the generating function of DT invariants in the large volume attractor chamber must be a vector-valued mock modular form with specified modular properties. In this work, we prove that this condition is also sufficient at two-instanton order. This is achieved by producing a holomorphic action of SL(2,Z) on the twistor space which preserves the holomorphic contact structure. The key step is to cancel the anomalous modular variation of the Darboux coordinates by a local holomorphic contact transformation, which is generated by a suitable indefinite theta series. For this purpose we introduce a new family of theta series of signature (2,n-2), find their modular completion, and conjecture sufficient conditions for their convergence, which may be of independent mathematical interest.

description: We use N-body simulations to quantify how the escape velocity in cluster-sized halos maps to the gravitational potential in a LambdaCDM universe. Using spherical density-potential pairs and the Poisson equation, we find that the matter density inferred gravitational potential profile predicts the escape velocity profile to within a few percent accuracy for group and cluster-sized halos (10^13 < M_200 < 10^15 M_sun, with respect to the critical density). The accuracy holds from just outside the core to beyond the virial radius. We show the importance of explicitly incorporating a cosmological constant when inferring the potential from the Poisson equation. We consider three density models and find that the Einasto and Gamma profiles provide a better joint estimate of the density and potential profiles than the Navarro, Frenk and White profile, which fails to accurately represent the escape velocity. For individual halos, the 1 sigma scatter between the measured escape velocity and the density-inferred potential profile is small (<5%). Finally, while the sub-halos show 15% biases in their representation of the particle velocity dispersion profile, the sub-halo escape velocity profile matches the dark matter escape velocity profile to high accuracy with no evidence for velocity bias outside 0.4r_200.

Shaping the Byzantine Chanting Tradition of Thessaloniki: The Constantinopolitans’ Impact in the First Half of the 20th century
Creators: name: Chovardas, Panagiotis
Publisher: name: Series Musicologica Balcanica
Year: 2020
Subjects: Constantinopolitan chanters; chanting tradition of Thessaloniki; Greek Orthodox church music.

description: This paper attempts to highlight the significant role of Constantinopolitan chanters in the development of the Greek Orthodox church music of Thessaloniki. Due to historical circumstances, a large number of chanters from Constantinople arrived successively in the region of Thessaloniki during the first half of the 20th century. Their higher music education and undisputed chanting experience made them rapidly notorious. They were very much appreciated by church commissioners, who often hired them for church services. Their contribution is also certified in the domains of byzantine music teaching, book and newspaper publishing, while at the same time they were very socially active, by supporting many local cultural or artistic unions and charity organisations. The dominant presence of the Constantinopolitan chanters gave a new meaning to the ecclesiastical life of Thessaloniki, changing the people’s perception towards the liturgical music of the Greek Orthodox church. Most of the material examined for this paper derives from the archives of the Chanters Union of Thessaloniki (Σωματείο Ιεροψαλτών Θεσσαλονίκης ‘Ιωάννης ο Δαμασκηνός’), established in 1903, and also from private archives of long gone Constantinopolitan chanters. Furthermore, other known basic methods of research in the field, such as interviews and participant observation, were implemented.

Year: 2017
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Images and spectra of the open cluster NGC 3105 have been obtained with GMOS on Gemini South. The (i', g'-i') color-magnitude diagram (CMD) constructed from these data extends from the brightest cluster members to g'~23. This is 4 - 5 mag fainter than previous CMDs at visible wavelengths and samples cluster members with sub-solar masses. Assuming a half-solar metallicity, comparisons with isochrones yield a distance of 6.6+/-0.3 kpc. An age of at least 32 Myr is found based on the photometric properties of the brightest stars, coupled with the apparent absence of pre-main sequence stars in the lower regions of the CMD. The luminosity function of stars between 50 and 70 arcsec from the cluster center is consistent with a Chabrier lognormal mass function. However, at radii smaller than 50 arcsec there is a higher specific frequency of the most massive main sequence stars than at larger radii. Photometry obtained from archival SPITZER images reveals that some of the brightest stars near NGC 3105 have excess infrared emission, presumably from warm dust envelopes. Halpha emission is detected in a few early-type stars in and around the cluster, building upon previous spectroscopic observations that found Be stars near NGC 3105. The equivalent width of the NaD lines in the spectra of early type stars is consistent with the reddening found from comparisons with isochrones. Stars with i'~18.5 that fall near the cluster main sequence have a spectral-type A5V, and a distance modulus that is consistent with that obtained by comparing isochrones with the CMD is found assuming solar neighborhood intrinsic brightnesses for these stars.

description: The cooling of type-I X-ray bursts can be used to probe the nuclear burning conditions in neutron star envelopes. The flux decay of the bursts has been traditionally modelled with an exponential, even if theoretical considerations predict power-law-like decays. We have analysed a total of 540 type-I X-ray bursts from five low-mass X-ray binaries observed with the Rossi X-ray Timing Explorer. We grouped the bursts according to the source spectral state during which they were observed (hard or soft), flagging those bursts that showed signs of photospheric radius expansion (PRE). The decay phase of all the bursts were then fitted with a dynamic power-law index method. This method provides a new way of probing the chemical composition of the accreted material. Our results show that in the hydrogen-rich sources the power-law decay index is variable during the burst tails and that simple cooling models qualitatively describe the cooling of presumably helium-rich sources 4U 1728-34 and 3A 1820-303. The cooling in the hydrogen-rich sources 4U 1608-52, 4U 1636-536, and GS 1826-24, instead, is clearly different and depends on the spectral states and whether PRE occurred or not. Especially the hard state bursts behave differently than the models predict, exhibiting a peculiar rise in the cooling index at low burst fluxes, which suggests that the cooling in the tail is much faster than expected. Our results indicate that the drivers of the bursting behaviour are not only the accretion rate and chemical composition of the accreted material, but also the cooling that is somehow linked to the spectral states. The latter suggests that the properties of the burning layers deep in the neutron star envelope might be impacted differently depending on the spectral state.

description: The poor contrast and the overlapping of cervical cell cytoplasm are the major issues in the accurate segmentation of cervical cell cytoplasm. This paper presents an automated unsupervised cytoplasm segmentation approach which can effectively find the cytoplasm boundaries in overlapping cells. The proposed approach first segments the cell clumps from the cervical smear image and detects the nuclei in each cell clump. A modified Otsu method with prior class probability is proposed for accurate segmentation of nuclei from the cell clumps. Using distance regularized level set evolution, the contour around each nucleus is evolved until it reaches the cytoplasm boundaries. Promising results were obtained by experimenting on ISBI 2015 challenge dataset.

description: We examine a generalised Randomised Response (RR) technique in the context of differential privacy and examine the optimality of such mechanisms. Strict and relaxed differential privacy are considered for binary outputs. By examining the error of a statistical estimator, we present closed solutions for the optimal mechanism(s) in both cases. The optimal mechanism is also given for the specific case of the original RR technique as introduced by Warner in 1965.

description: Additional file 5: Figure S5. The regression model and residuals are consistent across multiple training and verification cohorts and potential confounding variables (array synthesis, ethnicity, sample collection site, and BMI). (A) The age regression residuals are consistent across multiple sub-training sets. The Training Cohort and Verification Cohorts were merged into a single large cohort (N = 1675). Two training sets were created, each of size 698, which left 279 samples as a holdout set. An elastic net regression model was trained on each of the training sets and then residuals were calculated on the holdout set of 279 samples (data points) using each of the models (axes). High correlation between model residuals suggests a low variance-error term, which is consistent with residuals potentially being biologically relevant. Result is representative of 100 simulated training set splits. (B) Age regression residuals (axes) are correlated when samples are assayed on different array formats, different training sets, and different algorithm parameters (subplots). Each dot is a single donor assayed for a single permutation of array type, training set, and algorithm parameters. Not all samples were assayed on all permutations of array type. Values on x- and y-axes are residuals, which normalize out the default transitive correlation of all models being correlated to chronological age. (C) Regression model yields similar results across samples binned by ethnicity and sample collection site. Each dot is single donor and each line shows regression predictions on grouped donors. Chronological age (x-axis) and prediction of age based on peptide array regression model (y-axis) are shown. Legend shows correlation coefficient, regression slope and intercept, and number of samples in a given bin. Data shown is regression model learned on Training Cohort and applied to the Verification Cohort. (D) The intercept (shift) and slope (interacting) terms associated with BMI, ethnicity, and collection state are not statistically significant. One-way ANOVA test statistics are shown in the Table. (E) Age-associated antibody-peptide binding to di-serine N-terminus peptides is highly consistent in a long-term study. A total of N = 16 donors consented to regular blood draws for > 1 yr. Donors with > 5 samples over > 1 yr (N = 13) had consistent age-regression values over this time period. Data shown for all donors (lines).

description: The number of trees T in the random forest (RF) algorithm for supervised learning has to be set by the user. It is controversial whether T should simply be set to the largest computationally manageable value or whether a smaller T may in some cases be better. While the principle underlying bagging is that "more trees are better", in practice the classification error rate sometimes reaches a minimum before increasing again for increasing number of trees. The goal of this paper is four-fold: (i) providing theoretical results showing that the expected error rate may be a non-monotonous function of the number of trees and explaining under which circumstances this happens; (ii) providing theoretical results showing that such non-monotonous patterns cannot be observed for other performance measures such as the Brier score and the logarithmic loss (for classification) and the mean squared error (for regression); (iii) illustrating the extent of the problem through an application to a large number (n = 306) of datasets from the public database OpenML; (iv) finally arguing in favor of setting it to a computationally feasible large number, depending on convergence properties of the desired performance measure.

description: There is an urgent need for collective action to mitigate the consequences of climate change and adapt to unavoidable changes. The complexity of climate change issues can pose educational challenges. Nonetheless, education has a key role to play in ensuring that younger generations have the required knowledge and skills to understand issues surrounding climate change, to avoid despair, to take action, and to be prepared to live in a changing world. The Office for Climate Education (OCE) was founded in 2018 to promote strong international cooperation between scientific organisations, educational institutions and NGOs. The overall aim of the OCE is to ensure that the younger generations of today and tomorrow are educated about climate change. Teachers have a key role to play in their climate education and it is essential that they receive sufficient support to enable them to implement effective lessons on climate change. The OCE has developed a range of educational resources and professional development modules to support them in teaching about climate change with active pedagogy.
The angular momentum of cosmological coronae and the inside-out growth of spiral galaxies

description: Massive and diffuse haloes of hot gas (coronae) are important intermediaries between cosmology and galaxy evolution, storing mass and angular momentum acquired from the cosmic web until eventual accretion on to star-forming discs. We introduce a method to reconstruct the rotation of a galactic corona, based on its angular momentum distribution (AMD). This allows us to investigate in what conditions the angular momentum acquired from tidal torques can be transferred to star forming discs and explain observed galaxy-scale processes, such as inside-out growth and the build-up of abundance gradients. We find that a simple model of an isothermal corona with a temperature slightly smaller than virial and a cosmologically motivated AMD is in good agreement with galaxy evolution requirements, supporting hot-mode accretion as a viable driver for the evolution of spiral galaxies in a cosmological context. We predict moderately sub-centrifugal rotation close to the disc and slow rotation close to the virial radius. Motivated by the observation that the Milky Way has a relatively hot corona (T ~ 2 x 10^6 K), we also explore models with a temperature larger than virial. To be able to drive inside-out growth, these models must be significantly affected by feedback, either mechanical (ejection of low angular momentum material) or thermal (heating of the central regions). However, the agreement with galaxy evolution constraints becomes, in these cases, only marginal, suggesting that our first and simpler model may apply to a larger fraction of galaxy evolution history.
