magnetic drag

description: Ultra-hot Jupiters represent an exciting avenue for testing extreme physics and observing atmospheric circulation regimes not found in our solar system. These high temperatures result in ionized particles moving through the atmosphere, generating magnetic fields in the planet. Previous treatments of magnetic drag in 3D GCMs of ultra-hot Jupiters have mostly been uniform drag timescales applied evenly throughout the planet. In this work, we apply our locally calculated active magnetic drag treatment in our GCM of the planet WASP-76b. We find the effects of this treatment to be most pronounced in the planet's upper atmosphere, where strong differences between the day and night side circulation are present. These circulation effects alter the resulting phase curves by reducing the hotspot offset. This work highlights the importance of considering magnetic effects when modeling ultra-hot Jupiters.

description: I derive and test predictions from the classic Mussa and Rosen (1978) second-degree price discrimination model using data from the United States clothes washer market. I find evidence consistent with price discrimination in the market response to energy efficiency policy changes. Concurrent with the effective dates of both the new 2004 and 2007 federal minimum efficiency and ENERGY STAR standards, within-model clothes washer prices dropped on average. The heterogeneous pattern of price reduction across market segments, and adjustments in the menu of products, were consistent with predictions from the price-discrimination model, and not with a perfectly competitive market.

Debris Rings From Extrasolar Irregular Satellites
Creators: name: Hayakawa, Kevin
Publisher: name: Zenodo
Year: 2021

description: Irregular satellites are the minor bodies found orbiting all four Solar System giant planets with large semimajor axes, eccentricities, and inclinations. Previous studies have determined that the Solar System's irregular satellites are extremely collisionally evolved populations today, having lost ~99% of their initial mass over the course of hundreds of Myr. In this paper, we show that circumstellar disks can result from the dust generated by these collisions. Radiation pressure, quantified by the parameter \(\beta\), is the driving force behind the liberation of dust grains from the planetary Hill sphere. Our simulated disks reproduce many of the same features seen in observed debris disks, such as thin ring morphology, a large blowout size, and azimuthal symmetry. By comparing the dust grain collisional timescale with the residence timescale as a function of size, we identify a critical intersection of (\(\beta \approx 0.1, t \approx 10\ years\)) that tells us the minimum size at which dust grains can exit the Hill sphere and how long it will take. Since a relation exists between \(\beta\), dust grain size, and observing wavelength, this also provides a future road map for observers. Due to how short the intersection timescale is, we do not expect to observe any long-lived circumplanetary "irregular satellite disks," since large dust grains will grind down to smaller dust grains, and small dust grains will quickly escape the Hill sphere. We compare our simulated disks' radial profiles to those of Fomalhaut and HR 4796A. We find that all three systems satisfy the definition of a narrow ring put forth by Hughes et al. (2018), \(\dfrac{\Delta R}{R} < 0.5\).

description: In the realm of granular bedforms, barchan dunes are strong attractors that can be found in rivers, terrestrial deserts and other planetary environments. These bedforms are characterized by a crescentic shape, which, although robust, presents different scales according to the environment they are in, their length scale varying from the decimeter under water to the kilometer on Mars. In addition to the scales of bedforms, the transport of grains presents significant differences according to the nature of the entraining fluid, so that the growth of barchans rests to be fully understood. Given the smaller length and time scales of the aquatic case, subaqueous barchans are the ideal object to study the growth of barchan dunes. In the present paper, we reproduce numerically the experiments of Alvarez and Franklin [Phys. Rev. E 96, 062906 (2017) and Phys. Rev. Lett. 121, 164503 (2018)] on the shape evolution of barchans from their initiation until they have reached a stable shape. We computed the bed evolution by using computational fluid dynamics - discrete element method (CFD-DEM), where we coupled DEM with large eddy simulation (LES) for the same initial and boundary conditions of experiments, performed in a closed-conduit channel where initially conical heaps evolved to single barchans under the action of a water flow in turbulent regime. Our simulations captured well the evolution of the initial pile toward a barchan dune in both the bedform and grain scales, with the same characteristic time and lengths observed in experiments. In addition, we obtained the local granular flux and the resultant force acting on each grain, the latter not yet previously measured nor computed. This shows that the present method is appropriate to numerical computations of bedforms, opening new possibilities for accessing data that are not available from current experiments.

description: Nonostante venga riconosciuta a Lorenzo Magalotti una non trascurabile statura nel contesto culturale seicentesco italiano ed europeo, la sua figura ha ricevuto, nel corso del Novecento, interpretazioni decisamente contrastanti. La valutazione della sua opera è oscillata, in qualità di segretario del Cimento ed estensore dei Saggi di naturali esperienze, tra gli estremi dello sperimentalismo galileiano e quelli, veicolati dai suoi scritti sull’«odorismo», di una poesia raffinata e «decadente» nutrita dalla «svogliatura del secolo». In generale, tuttavia, si è cercato di imbrigliarne il percorso biografico e intellettuale negli schemi interpretativi del barocco italiano da cui, a dire il vero, egli sembra distaccarsi in punti rilevanti. In questo saggio si sintetizzano le principali linee interpretative lungo le quali si è mossa la critica magalottiana nel corso del XXI secolo, presentando in conclusione alcune prospettive di ricerca basate sulla grande quantità di materiale autografo tuttora inedito.

Since then, both the experimental precision and the theoretical framework have evolved a lot as well as the computing technology. Both the new and the earlier data are to be analysed by a highly modernised version of the earlier approach. Especially the propagation of the measurement errors in the analysis will be considered in detail, visualisation tools will be developed using the Python/Tkinter combination, and the huge data base of experiments will be handled by MySQL.

Then they follow Djedefre, Khafre, Bicheris, Menkaure, Shepseskaf and (perhaps) Djedefptah. Of the kings of the IV Dynasty here we consider the pyramids, to investigate the orientation of their entrances and burial chambers. If possible, the orientation of the sarcophagus is mentioned. The four pyramids built by Snefru show the evolution to the final model with a north entrance and a burial chamber east-west oriented. Then, the pyramids of the Fifth Dynasty are investigated regarding their substructures, which show a coherent orientation. The Sekhemkhet (Djoserty) pyramid of the Third Dynasty is also illustrated for comparison. The position of the sarcophagus and of the body inside is also investigated. In this framework, we propose again what told in 2016, https://arxiv.org/abs/1604.05963

description: Il manoscritto che pubblichiamo è conservato nella Biblioteca Nazionale Centrale di Firenze (Ms.Magl.X.65). Si tratta, in realtà di due documenti separati: il primo contiene notizie scritte direttamente dal Magliabechi; il secondo è un sunto, in bella copia, del precedente, ma non è del Magliabechi e contiene vari errori di copiatura. La prima parte si presenta sotto forma di lettera, forse indirizzata a Lorenzo Panciatichi o a qualcun altro del seguito di Leopoldo de’ Medici. Molto probabilmente si tratta di note che servirono al Magliabechi per compilare i fogli che periodicamente mandava al cardinale Leopoldo a Roma. Il documento è relativo alle osservazioni che il Magliabechi fece all’Index Librorum Prohibitorum curato dal padre Vincenzo Fano (1670), segnalando tutti gli errori in cui era incorso il segretario della Congregazione dell’indice. Errori, secondo il Magliabechi, strutturali perché quello che per il padre Fano doveva rappresentare il vanto della pubblicazione, in realtà, costituiva la fonte maggiore degli errori e delle confusioni che potevano nascere quando si consultava, a cominciare dai criteri di indicizzazione: un autore, infatti, si trovava sotto l’ordine alfabetico del nome proprio, del cognome e, a volte, si rimandava al titolo dell’opera proibita.

Does group reflective practice change how trainee clinical psychologists think about their clients? An Interpretative Phenomenological Analysis.
Creators: name: Biggins, Anya

Year: 2019

description: Reflective practice groups are increasingly common in clinical services and training programmes in health and social care. They are seen as a method of learning from experience and thus as a way of supporting continued professional development and improving practice. Despite the growing popularity of reflective practice groups, the relevant research remains disparate, spread across multiple fields of practice and academia. Moreover, a large section of the current literature is focused on the impact of reflective practice and staff wellbeing, as opposed to the clinical value of attending a reflective practice group.Literature Review:The literature review aims to highlight the experiences of those taking part in reflective processes within health and social care environments. Five themes were generated from twelve empirical studies exploring methods of reflective practice within professional training or practice. Key themes were: facilitator qualities; security in the setting and relational security; ambiguous experiences of written reflection; self-reflection and time and developing reflective skills.Research Report:Semi-structured interviews were conducted with five Trainee Clinical Psychologists who had attended monthly reflective practice seminars as part of their training. Audio excerpts from previously recorded reflective practice seminars were played within the participant interviews; it was felt that the excerpts would support participants’ recall of the seminars and facilitate the collection of rich and meaningful interview data. Interviews were analysed using Interpretative Phenomenological Analysis (IPA). The analysis highlighted how presenting clinical material and hearing multiple perspectives from group colleagues impacted on how participants’ thought about their clients. Moreover, participants were able to appreciate the view point of their client, following discussing the case in reflective practice, and acquire an increased sense of compassion.

description: Ferromagnetic quantum criticality in clean metals has proven elusive due to fermionic soft modes that drive the transition first order. We show that non-centrosymmetric metals with a strong spin-orbit interaction provide a promising class of materials for realizing a ferromagnetic quantum critical point in clean systems. The spin-orbit interaction renders massive the soft modes that interfere with quantum criticality in most materials, while the absence of spatial inversion symmetry precludes the existence of new classes of soft modes that could have the same effect.

description: L’articolo si sofferma sul racconto dell’origine delle parti guelfa e ghibellina a Firenze: il conflitto fazioso sarebbe stato innescato da una faida tra alcune famiglie dell’aristocrazia fiorentina, specialmente Buondelmonti, Amidei e Fifanti. Il racconto ci è stato tramandato da vari autori, tra i quali Dante, Giovanni Villani e Dino Compagni; in questa tradizione riconosciamo almeno due versioni, differenti per alcuni particolari degni di nota. Ancor più significativo per le sue implicazioni politiche è il momento in cui questa storia venne messa per scritto. Al cuore del problema sta la vendetta privata e il modo diverso in cui fu considerata dagli antichi scrittori di storia fiorentina: ignorata, approvata, oppure radicalmente condannata.

description: We obtain singularity resolutions for various overlapping brane configurations, including those of two heterotic 5-branes, type II 5-branes or D4-branes. In these solutions, the ``harmonic'' function H for each brane component depends only on the associated four-dimensional relative transverse space. The resolution is achieved by replacing these transverse spaces with Eguchi-Hanson or Taub-NUT spaces, both of which admit a normalisable self-dual (or anti-self-dual) harmonic 2-form. Due to the manner in which the interaction terms for the form fields modify their Bianchi identities or equations of motion, these normalisable harmonic 2-forms provide regular sources for the branes. We also obtain resolved 5-branes and D4-branes wrapped on S^1, which is fibred over the transverse Eguchi-Hanson or Taub-NUT spaces. The T-duality invariance of the NS-NS 5-brane is retained after the resolution. The resolved 5-branes and D4-branes provide regular supergravity duals of certain supersymmetric Yang-Mills theories in five and four dimensions.

description: In state-of-the-art positron emission (PET) tomography systems, application-specific integrated circuits (ASICs)are commonly used to precisely digitize the signals of analog silicon photo-multipliers (SiPMs). However, when operating PET electronics in a magnetic resonance (MR) system, one faces the challenge of mutual interference of these imaging techniques. To prevent signal deterioration along long analog signal lines, PET electronics with a low power consumption digitizing the signals close to the SiPMs are preferred. In this study, we evaluate the power consumption of the TOFPET2 ASIC. Its power consumption ranges from 3.6 to 7.2 mW/channel as a function of the input stage impedance and discriminator noise settings. We present an analytical model allowing to compute the power consumption of a given ASIC configuration. The configured input stage impedance and discriminator noise have an impact on the coincidence resolution time, energy resolution, and photon trigger level. Since the TOFPET2 ASIC delivers state-of-the-art performance with a power consumption similar or even lower than other ASICs typically used for PET applications, it is a favorable candidate to digitize the signals of SiPMs in future simultaneous PET/MR systems.

description: Atmospheric circulation is often clustered in so-called circulation regimes, which are persistent and recurrent patterns. For the Euro-Atlantic sector in winter, most studies identify four regimes: the Atlantic Ridge, the Scandinavian Blocking and the two phases of the North Atlantic Oscillation. These results are obtained by applying k-means clustering to the first several empirical orthogonal functions (EOFs) of geopotential height data. Studying the observed circulation in reanalysis data, it is found that when the full field data is used for the k-means cluster analysis instead of the EOFs, the optimal number of clusters is no longer four but six. The two extra regimes that are found are the opposites of the Atlantic Ridge and Scandinavian Blocking, meaning they have a low-pressure area roughly where the original regimes have a high-pressure area. This introduces an appealing symmetry in the clustering result. Incorporating a weak persistence constraint in the clustering procedure is found to lead to a longer duration of regimes, extending beyond the synoptic timescale, without changing their occurrence rates. This is in contrast to the commonly-used application of a time-filter to the data before the clustering is executed, which, while increasing the persistence, changes the occurrence rates of the regimes. We conclude that applying a persistence constraint within the clustering procedure is a superior way of stabilizing the clustering results than low-pass filtering the data.

description: The heterotic string free fermionic formulation produced a large class of three generation models, with an underlying SO(10) GUT symmetry which is broken directly at the string level by Wilson lines. A common subset of boundary condition basis vectors in these models is the NAHE set, which corresponds to Z2 X Z2 orbifold of an SO(12) Narain lattice, with (h11,h21)=(27,3). Alternatively, a manifold with the same data is obtained by starting with a Z2 X Z2 orbifold at a generic point on the lattice, with (h11,h21)=(51,3), and adding a freely acting Z2 involution. The equivalence of the two constructions is proven by examining the relevant partition functions. The explicit realization of the shift that reproduces the compactification at the free fermionic point is found. It is shown that other closely related shifts reproduce the same massless spectrum, but different massive spectrum, thus demonstrating the utility of extracting information from the full partition function. A freely acting involution of the type discussed here, enables the use of Wilson lines to break the GUT symmetry and can be utilized in non-perturbative studies of the free fermionic models.

Applied methods in hypergraph modeling
Creators: name: He, Yichen
Publisher: name: No Publisher Supplied
Year: 2023

description: While statistical network models have been explored in decades, it becomes more evident that graph representation of relational data is less expressive in modeling modern interaction data. As a more natural candidate for complex system, statistical hypergraph models have gained momentum recently as an emerging interdisciplinary field for two reasons. On the one hand, hypergraph models provide more faithful representation of multi-way interaction data without loss of information. On the other hand, the new-born field remains surprisingly underexplored. Equipped with the well-developed methods and algorithms from various disciplines, including graph theory, Physics and Computational Geometry, hypergraph modeling has been one of most promising directions in statistical network analysis. Many classical statistical network models with graph-representation naturally extend to hypergraph model cases. The thesis is organized as follows: First, I sketch the history of a well-known family in network science, Exponential Random Graph Model (ERGM) that lays theoretical and methodological foundation for modern network modeling. Then recent network models beyond ERGM are discussed. The incomplete list includes multiview graphs models, dynamic graph models, hypergraph models and exchangeable models. Second, it follows popular algorithms and methods in maximum likelihood inference, widely applied in statistical network modeling. I outline connections among gradient descent methods including steepest descent, Fisher's method, Newton's method and quasi Newton's method. Iterative proportional scaling is popular for its scalability and robustness. Pseudo-likelihood methods are widely used in the Markov graph $p^*$ model. Minorize-maximization methods and expectation-maximization are suitable for latent variable models. Monte Carlo methods are attractive for its universality and ease-of-use. Variational methods treat inference problems as optimization problems. Third, we propose a new class of latent space models on general hypergraphs. By introducing volume of convex hull in latent space, we extend the latent space distance model to the hypergraph case and propose four variants of Monte Carlo expectation-maximization. Fourth, we propose a clustering model for general hypergraphs. Our model captures community patterns in a latent nodal space and allows for mixed membership for every node. Variational EMs are proposed in maximum likelihood inference. Last, we discuss future work in hypergraph modeling.
Un’associazione di patronato a Firenze: la “Famiglia del volontario trentino”

description: L’articolo approfondisce la vicenda della “Famiglia del Volontario Trentino”, un’associazione di patronato nata a Firenze nell’autunno del 1915 con lo scopo di aiutare moralmente e materialmente quei trentini che, fuggiti dalla loro terra, allora territorio austriaco, si arruolarono come volontari nell’esercito italiano durante il primo conflitto mondiale. La scelta del capoluogo toscano testimonia il forte legame esistente tra le terre irredente e quella che allora veniva chiamata «L’Atene d’Italia», la città che, con la sua storia, meglio incarnava quell’Italia idealizzata così diffusa tra gli irredentisti. La Famiglia del Volontario Trentino è gestita unicamente da donne e rappresenta un caso assolutamente particolare: in altre associazioni analoghe, infatti, sebbene le donne organizzino e gestiscano quasi ogni attività non arrivano mai a cariche di rilievo (fino al 1919 le donne non hanno personalità giuridica). Gruppi di delegate si costituiranno in ben 25 città e nel luglio del 1918 riusciranno anche ad aprire, vicino a Forte dei Marmi, una casa di cura per i volontari feriti.

description: If captured by the gravitational field of stars or other compact objects, dark matter can self-annihilate and produce a potentially detectable particle flux. In the case of superheavy dark matter ($ m_{X} \gtrsim 10^{8} GeV $), a large number of scattering events with nuclei inside stars are necessary to slow down the dark matter particles below the escape velocity of the stars, at which point the Dark Matter (DM) particle becomes trapped, or captured. Using the recently developed analytical formalism for multiscatter capture, combined with the latest results on the constraints of dark-matter-baryon scattering cross-section, we calculate upper bounds on the capture rates for superheavy dark matter particles by the first (Pop. III) stars. Assuming that a non-zero fraction of the products of captured superheavy dark matter (SHDM) annihilations can be trapped and thermalized inside the star we find that this additional heat source could influence the evolutionary phase of Pop. III stars. Moreover, requiring that Pop. III stars shine with sub-Eddington luminosity, we find upper bounds on the masses of the Pop. III stars. This implies a DM dependent cutoff on the initial mass function (IMF) of Pop. III stars, thus opening up the intriguing possibility of constraining DM properties using the IMF of extremely metal-poor stars.

description: This study attempts at estimating, with a discrete choice experiment, the preference of longan (Dimocarpus longan) farmers for changes in the population of native bees and for three (widely recognized) strategies to conserve them in Chiang Mai Province, Thailand. Thereby, the part-worth utilities of these policy attributes were estimated with a conditional logit model, indicating a positive contribution, ceteris paribus, of the analyzed policy elements to the probability of a conservation policy profile being chosen. The inclusion of a cost attribute allowed the calculation of willingness to pay estimates. Significant taste heterogeneity was also identified within a mixed logit model.

description: Literature Review:The relationship between Eating Disorder (ED) symptomology and Body Dissatisfaction (BD) is well established, yet there is a discrepancy in the number of people who experience BD and those reporting ED symptoms. The present literature review aimed to explore this relationship further by examining potential mediating or moderating variables. It specifically focused on one ED subgroup, bulimic symptomatology. Sixteen relevant articles were identified during a systematic search of the literature. A narrative synthesis of findings revealed negative affect was most consistently supported as a mediating variable. Few studies investigated potential moderating variables. More research is needed that addresses the methodological limitations identified, and to further clarify the relationship between BD and bulimic symptomatology. Limitations and implications for future research was also discussed.Empirical Paper:Compassion Focused Therapy has been specifically adapted for people with an ED diagnosis (CFT-E). Following a clinical audit which demonstrated promising preliminary findings of a compassion-focused intervention, the treatment-programme was developed to create a stronger grounding in on CFT theory and practice. The present study aimed to investigate the impact of the updated treatment-programme (CFT-E2) on ED symptoms, psychological distress, shame, self-criticism and self-compassion. Data routinely collected during a CFT-E2 group-based treatment-programme offered in an outpatient ED service, was analysed. Findings demonstrated significant improvements in ED symptoms and psychological distress following CFT-E2. Levels of self-compassion also improved, as did some aspect of self-criticism. Overall, levels of shame decreased, but changes were not significant. Clinically significant and reliable change calculations indicate 48% of participants improve or recover following CFT-E2, which is comparable (and to some extent better) to the earlier CFT-E treatment-programme. Taken together, the findings offer promising evidence for the application of CFT-E2 in the treatment of clinical EDs. This has important clinical implications. Limitations and implications for future research was also discussed.

description: An exhaustive numerical investigation of the growth of magnetic films in confined $(d+1)$-dimensional stripped geometries ($d=1,2$) is carried out by means of extensive Monte Carlo simulations. Thin films in contact with a thermal bath are grown by adding spins with two possible orientations and considering ferromagnetic (nearest-neighbor) interactions. At low temperatures, it is observed that the films exhibit ``spontaneous magnetization reversals'' during the growth process. Furthermore, it is found that for $d=1$ the system is non-critical, while a continuous order-disorder phase transition at finite temperature takes place in the $d=2$ case. Using standard finite-size scaling procedures, the critical temperature and some relevant critical exponents are determined. Finally, the growth of magnetic films in $(2+1)$ dimensions with competing short-range magnetic fields acting along the confinement walls is studied. Due to the antisymmetric condition considered, an interface between domains with spins having opposite orientation develops along the growing direction. Such an interface undergoes a localization-delocalization transition that is the precursor of a wetting transition in the thermodynamic limit. Furthermore, the growing interface also undergoes morphological transitions in the growth mode. A comparison between the well-studied equilibrium Ising model and the studied irreversible magnetic growth model is performed throughout. Although valuable analogies are encountered, it is found that the nonequilibrium nature of the latter introduces new and rich physical features of interest.

description: Il nostro recente progetto è finalizzato alla conoscenza della risorsa archeologica di Firenze. In particolare la nostra attenzione si è concentrata sugli aspetti legati alle trasformazioni della città tra tarda antichità e medioevo: i cambiamenti nell’economia cittadina, le forme urbanistiche che Florentia assunse nella lunga transizione tra III e vIII secolo, la riurbanizzazione bassomedievale e le ancor più significative vicende che portarono alla formazione della città del Rinascimento. L’obiettivo consiste nel riscrivere, sulla base di nuove fonti, processi ancora non messi a fuoco, contribuendo a ridefinire lo sviluppo contemporaneo della città sulla base dei segni materiali della storia.

description: The paper examines the innovation and export strategies of Spanish food and agriculture firms. It is based on a sample of these firms selected by PITEC for the period 2003-2010. The results show the key role of internal innovation efforts in international commercial activity. This highlights the importance of the capacity to absorb internal innovation efforts. Furthermore, process innovation has a greater effect than product innovation on the internationalization strategy, both for the agricultural and the food firms.

description: In this study, an extended TPB model is set up for purchasing behaviour of regional pork. It refers to research on organic food purchasing and on influences from region-of-origin labelling on product evaluation. Besides cognitive attitudes, subjective norms and perceived behavioural control, the model includes an element of personal norms and affective attitudes. Furthermore, identification with and perceived authenticity of a labelled region are considered. Empirical findings for 485 citizens of the German Federal State NRW imply that normative and affective determinants are most relevant for consumers’ purchasing intention. With respect to the impact of a stated region-of-origin, the identification with a region is a significant determinant of positive product evaluation by personal norms and affective attitudes. Respectively, the product-specific authenticity of a region determines cognitive attitudes towards the regional product.

description: NIKA2 is a dual-band millimetric continuum camera of 2900 Kinetic Inductance Detectors (KID), operating at $150$ and $260\,\rm{GHz}$, installed at the IRAM 30-meter telescope. We present the performance assessment of NIKA2 after one year of observation using a dedicated point-source calibration method, referred to as the \emph{baseline} method. Using a large data set acquired between January 2017 and February 2018 that span the whole range of observing elevations and atmospheric conditions encountered at the IRAM 30-m telescope, we test the stability of the performance parameters. We report an instantaneous field of view (FOV) of 6.5' in diameter, filled with an average fraction of $84\%$ and $90\%$ of valid detectors at $150$ and $260\,\rm{GHz}$, respectively. The beam pattern is characterized by a FWHM of $17.6'' \pm 0.1''$ and $11.1''\pm 0.2''$, and a beam efficiency of $77\% \pm 2\%$ and $55\% \pm 3\%$ at $150$ and $260\,\rm{GHz}$, respectively. The rms calibration uncertainties are about $3\%$ at $150\,\rm{GHz}$ and $6\%$ at $260\,\rm{GHz}$. The absolute calibration uncertainties are of $5\%$ and the systematic calibration uncertainties evaluated at the IRAM 30-m reference Winter observing conditions are below $1\%$ in both channels. The noise equivalent flux density (NEFD) at $150$ and $260\,\rm{GHz}$ are of $9 \pm 1\, \rm{mJy}\cdot s^{1/2}$ and $30 \pm 3\, \rm{mJy}\cdot s^{1/2}$. This state-of-the-art performance confers NIKA2 with mapping speeds of $1388 \pm 174$ and $111 \pm 11 \,\rm{arcmin}^2\cdot \rm{mJy}^{-2}\cdot \rm{h}^{-1}$ at $150$ and $260\,\rm{GHz}$. With these unique capabilities of fast dual-band mapping at high (better that 18'') angular resolution, NIKA2 is providing an unprecedented view of the millimetre Universe.

description: We have carried out a bulk-sensitive high-resolution photoemission experiment on Mn5Si3. The measurements are performed for both core level and valence band states. The Mn core level spectra are deconvoluted into two components corresponding to different crystallographic sites. The asymmetry of each component is of noticeable magnitude. In contrast, the Si 2p spectrum shows a simple Lorentzian shape with low asymmetry. The peaks of the valence band spectrum correspond well to the peak positions predicted by the former band calculation.
