description: The abundances of interstellar CH+ and SH+ are not well understood as their most likely formation channels are highly endothermic. Using data from Herschel, we study the formation of CH+ and SH+ in a typical high UV-illumination photon-dominated region (PDR), the Orion Bar. Herschel/HIFI provides velocity-resolved data of CH+ 1-0 and 2-1 and three hyperfine transitions of SH+. Herschel/PACS provides information on the excitation and spatial distribution of CH+ (up to J=6-5). The widths of the CH+ 2-1 and 1-0 transitions are of ~5 km/s, significantly broader than the typical width of dense gas tracers in the Orion Bar (2-3 km/s) and are comparable to the width of tracers of the interclump medium such as C+ and HF. The detected SH+ transitions are narrower compared to CH+ and have line widths of 3 km/s, indicating that SH+ emission mainly originates in denser condensations. Non-LTE radiative transfer models show that electron collisions affect the excitation of CH+ and SH+, and that reactive collisions need to be taken into account to calculate the excitation of CH+. Comparison to PDR models shows that CH+ and SH+ are tracers of the warm surface region (AV<1.5) of the PDR with temperatures between 500-1000 K. We have also detected the 5-4 transition of CF+ (FWHM=1.9 km/s) with an intensity that is consistent with previous observations of lower-J CF+ transitions toward the Orion Bar. A comparison to PDR models indicate that the internal vibrational energy of H2 can explain the formation of CH+ for typical physical conditions in the Orion Bar near the ionization front. H2 vibrational excitation is the most likely explanation of SH+ formation as well. The abundance ratios of CH+ and SH+ trace the destruction paths of these ions, and through that, indirectly, the ratios of H, H2 and electron abundances as a function of depth into the cloud.

description: The interaction of water molecules with metal surfaces is typically weak and as a result van der Waals (vdW) forces can be expected to be of importance. Here we account for the systematic poor treatment of vdW forces in most popular density functional theory (DFT) exchange-correlation functionals by applying accurate non-local vdW density functionals. We have computed the adsorption of a variety of exemplar systems including water monomer adsorption on Al(111), Cu(111), Cu(110), Ru(0001), Rh(111), Pd(111), Ag(111), Pt(111), and unreconstructed Au(111), and small clusters (up to 6 waters) on Cu(110). We show that non-local correlations contribute substantially to the water-metal bond in all systems, whilst water-water bonding is much less affected by non-local correlations. Interestingly non-local correlations contribute more to the adsorption of water on the reactive transition metal substrates than they do on the noble metals. The relative stability, adsorption sites, and adsorption geometries of competing water adstructures rarely differ when comparing results obtained with semi-local functionals and the non-local vdW density functionals, which explains the previous success of semi-local functionals in characterizing adsorbed water structures on a number of metal surfaces.

description: Context. β Pictoris b is one of the most studied objects nowadays since it was identified with VLT/NaCo as a bona-fide exoplanet with a mass of about 9 times that of Jupiter at an orbital separation of 8-9 AU. The link between the planet and the dusty disk is unambiguously attested and this system provides an opportunity to study the disk/planet interactions and to constrain formation and evolutionary models of gas giant planets. Still, β Pictoris b had never been confirmed with other telescopes so far. Aims. We aimed at an independent confirmation using a different instrument. Methods. We retrieved archive images from Gemini South obtained with the instrument NICI, which is designed for high contrast imaging. The observations combine coronagraphy and angular differential imaging and were obtained at three epochs in Nov. 2008, Dec. 2009 and Dec. 2010. Results. We report the detection with NICI of the planet β Pictoris b in Dec. 2010 images at a separation of 404 \pm 10 mas and P A = 212.1 \pm 0.7° . It is the first time this planet is observed with a telescope different than the VLT.

description: It is a well-known conjecture in the theory of irregularities of distribution that the L1 norm of the discrepancy function of an N-point set satisfies the same asymptotic lower bounds as its L^2 norm. In dimension d=2 this fact has been established by Halasz, while in higher dimensions the problem is wide open. In this note, we establish a series of dichotomy-type results which state that if the L^1 norm of the discrepancy function is too small (smaller than the conjectural bound), then the discrepancy function has to be large in some other function space.

description: This is a report on the new 122 ternary transition-metal pnictide of BaMn2Bi2, which is crystallized from bismuth flux. BaMn2Bi2 adopts ThCr2Si2-type structure (I4/mmm) with a = 4.4902(3) Å and c = 14.687(1) Å; it is antiferromagnetic with anisotropic magnetic susceptibility and semiconducting with a band gap of Eg = 6 meV. Heat capacity result confirms the insulating ground state in BaMn2Bi2 with the electronic residual Sommerfeld coefficient of γ ~ 0. The high temperature magnetization results show that magnetic ordering temperature is TN ~ 400 K. Hole-doping in BaMn2Bi2 via potassium in Ba1-xKxMn2Bi2 results in metallic behavior for x = 0.10(1), 0.32(1) and 0.36(1). With K-doping, more magnetically anisotropic behavior is observed. Although there is a downturn in electrical resistivity and low-field magnetization data below 4 K in > 30%-doped crystals, there is no sign of zero resistance or diamagnetism. This manuscript is a report on new materials of BaMn2Bi2 and Ba1-xKxMn2Bi2 (0 < x < 0.4). Results from powder X-ray diffraction, anisotropic temperature- and field-dependent magnetization, temperature-and field-dependent electrical resistivity, and heat capacity are presented.

description: We construct a class of exact ground states for correlated electrons on pentagon chains in the high density region and discuss their physical properties. In this procedure the Hamiltonian is first cast in a positive semidefinite form using composite operators as a linear combination of creation operators acting on the sites of finite blocks. In the same step, the interaction is also transformed to obtain terms which require for their minimum eigenvalue zero at least one electron on each site. The transformed Hamiltonian matches the original Hamiltonian through a nonlinear system of equations whose solutions place the deduced ground states in restricted regions of the parameter space. In the second step, nonlocal product wave functions in position space are constructed. They are proven to be unique ground states which describe non-saturated ferromagnetic and correlated half metallic states. These solutions emerge when the strength of the Hubbard interaction $U_i$ is site dependent inside the unit cell. In the deduced phases, the interactions tune the bare dispersive band structure such to develop an effective upper flat band. We show that this band flattening effect emerges for a broader class of chains and is not restricted to pentagon chains. For the characterization of the deduced solutions, uniqueness proofs, exact ground state expectation values for long-range hopping amplitudes and correlation functions are also calculated. The study of physical reasons which lead to the appearance of ferromagnetism has revealed a new mechanism for the emergence of an ordered phase, described here in details (because of lack of space see the continuation in the paper).

description: La pandemia Covid-19 ha comportato conseguenze e trasformazioni prefigurando scenari inediti sul piano economico, sociale e personale, determinando anche nel campo della ricerca l’urgenza di esplorarne le ricadute. Il volume dà quindi conto delle indagini svolte e in corso, sin dai primi giorni del lockdown, dai docenti e dai collaboratori del Dipartimento di Scienze della Formazione dell’Università Roma Tre, toccando i temi più diversi: dalla didattica a distanza, all’università e nei diversi ordini di scuola, al futuro dei servizi di orientamento, dal lavoro socio-educativo nelle varie tipologie di servizi all’impatto della pandemia sulle comunità, dalle narrazioni ai linguaggi artistici a contrasto di quest’emergenza non solo sanitaria. Si sono così esplorate le diverse educazioni possibili, riassegnando centralità ai processi formativi e al benessere delle persone, provando a tratteggiare nuovi paradigmi e prospettive.
description: Il presente studio intende esplorare il benessere “scolastico” di bambini e adolescenti con Disturbo Specifico dell’Apprendimento (DSA), considerando anche la condizione familiare e la Didattica a Distanza (DAD) ricevuta durante il primo lockdown (marzo-giugno 2020). Il campione include 256 studenti italiani (da 3a classe scuola primaria – a 3a classe scuola secondaria di I grado), di cui 74 con DSA e 182 controlli, appaiati per classe e genere. Le madri degli studenti hanno compilato un questionario online, attraverso cui sono state ricavate informazioni sul bambino, sulla madre, sulla DAD e sul benessere scolastico. I risultati evidenziano: i.) elevata presenza di comportamenti psicologici alterati in tutti gli studenti; ii.) peggioramento della condizione lavorativa ed economica materna di tutti gli studenti; iii.) sentimento di affatticamento/stress più alto nelle madri di studenti con DSA; iiii.) DAD caratterizzata da numero ridotto di lezioni sincrone e presenza di difficoltà attentive e motivazionali negli studenti, con riduzione o scomparsa di queste difficoltà solo nei controlli quando la DAD è intensa. Rispetto al benessere scolastico le madri degli studenti con DSA hanno riportato più problemi nei valutaione dei processi di apprendimento e nelle difficoltà emotive scolastiche, ma non nella consapevolezza delle loro prestazione e nella relazione con gli insegnanti, rispetto ai controlli.

description: A numerical scheme is described for including radiation in multi-dimensional general-relativistic conservative fluid dynamics codes. In this method, a covariant form of the M1 closure scheme is used to close the radiation moments, and the radiative source terms are treated semi-implicitly in order to handle both optically thin and optically thick regimes. The scheme has been implemented in a conservative general relativistic radiation hydrodynamics code KORAL. The robustness of the code is demonstrated on a number of test problems, including radiative relativistic shock tubes, static radiation pressure supported atmosphere, shadows, beams of light in curved spacetime, and radiative Bondi accretion. The advantages of M1 closure relative to other approaches such as Eddington closure and flux-limited diffusion are discussed, and its limitations are also highlighted.

description: We study localised activity patterns in neural field equations posed on the Euclidean plane; such models are commonly used to describe the coarse-grained activity of large ensembles of cortical neurons in a spatially continuous way. We employ matrix-free Newton-Krylov solvers and perform numerical continuation of localised patterns directly on the integral form of the equation. This opens up the possibility to study systems whose synaptic kernel does not lead to an equivalent PDE formulation. We present a numerical bifurcation study of localised states and show that the proposed models support patterns of activity with varying spatial extent through the mechanism of homoclinic snaking. The regular organisation of these patterns is due to spatial interactions at a specific scale associated with the separation of excitation peaks in the chosen connectivity function. The results presented form a basis for the general study of localised cortical activity with inputs and, more specifically, for investigating the localised spread of orientation selective activity that has been observed in the primary visual cortex with local visual input.

description: Short-duration gamma-ray bursts (SGRBs) are intense flashes of cosmic gamma-rays, lasting less than ~2 s, whose origin is one of the great unsolved questions of astrophysics today. While the favoured hypothesis for their production, a relativistic jet created by the merger of two compact stellar objects (specifically, two neutron stars, NS-NS, or a neutron star and a black hole, NS-BH), is supported by indirect evidence such as their host galaxy properties, unambiguous confirmation of the model is still lacking. Mergers of this kind are also expected to create significant quantities of neutron-rich radioactive species, whose decay should result in a faint transient in the days following the burst, a so-called "kilonova". Indeed, it is speculated that this mechanism may be the predominant source of stable r-process elements in the Universe. Recent calculations suggest much of the kilonova energy should appear in the near-infrared (nIR) due to the high optical opacity created by these heavy r-process elements. Here we report strong evidence for such an event accompanying SGRB 130603B. If this simplest interpretation of the data is correct, it provides (i) support for the compact object merger hypothesis of SGRBs, (ii) confirmation that such mergers are likely sites of significant r-process production and (iii) quite possibly an alternative, un-beamed electromagnetic signature of the most promising sources for direct detection of gravitational waves.

The black holes described by the solution are rotating but with zero total angular momentum and possess an ergoregion confined in a neighborhood of the horizon. Our results also show that the external magnetic field does not affect the black hole thermodynamics.

description: High precision metrology systems based on heterodyne interferometry can measure position and attitude of objects to accuracies of picometer and nanorad, respectively. A frequently found feature of the general system design is the subtraction of a reference phase from the phase of the position interferometer, which suppresses low frequency common mode amplitude and phase fluctuations occurring in volatile optical path sections shared by both, the position and reference interferometer. Spectral components of the noise at frequencies around or higher than the heterodyne frequency, however, are generally transmitted into the measurement band and may limit the measurement accuracy. Detailed analytical calculations complemented with Monte Carlo simulations show that high frequency noise components may also be entirely suppressed, depending on the relative difference of measurement and reference phase, which may be exploited by corresponding design provisions. Whilst these results are applicable to any heterodyne interferometer with certain design characteristics, specific calculations and related discussions are given for the example of the optical metrology system of the LISA Pathfinder mission to space.

The conjecture states that the Stokes matrix of the first structure connection of the Frobenius manifold constructed from the Gromov-Witten theory coincides with the Euler matrix of a full exceptional collection of the bounded derived category of the coherent sheaves. Our proof is based on the homological mirror symmetry, primitive forms of affine cusp polynomials and the Picard-Lefschetz theory.

description: Lithium-ion batteries have dominated the field of electrochemical energy storage for years due to their high energy density. Recently, with the rapid development of E-mobility, the quest for high power and high energy batteries with reduced production costs has aroused great interest and is still a huge challenge. The energy density at battery level can be increased by using electrodes with thicknesses > 150 μm. However, capacity fade of thick-film electrodes at C-rates > C/2 is observed. To compensate the capacity loss, 3D architectures with a high aspect ratio are produced using ultrafast laser ablation. In addition, aqueous processing of cathodes using water-based binders can achieve environmentally friendly production and cost reduction by replacing the conventional organic PVDF binder and the toxic and volatile NMP solvent. However, the pH value of aqueous processed cathode slurries increases to 12 due to the reaction between active material and water, which decreases the specific capacity of the cells and on the other side results in chemical corrosion of the current collector during casting. In order to determine the optimal pH range and avoid the damage of the current collector, slurries with pH values ranging from 8 to 12 are manufactured. In this work, thick-film Li(Ni0.6Mn0.2Co0.2)O2 electrodes are manufactured with aqueous binders and acid adjustment, and are subsequently structured using ultrafast laser ablation. This combination is beneficial to achieve green production, low cost, high power, and high energy application of lithium-ion batteries.

description: As the technology of gravitational-wave and neutrino detectors becomes increasingly mature, a multi-messenger era of astronomy is ushered in. Advanced gravitational wave detectors are close to making a ground-breaking discovery of gravitational wave bursts (GWBs) associated with mergers of double neutron stars (NS-NS). It is essential to study the possible electromagnetic (EM) and neutrino emission counterparts of these GWBs. Recent observations and numerical simulations suggest that at least a fraction of NS-NS mergers may leave behind a massive millisecond magnetar as the merger product. Here we show that protons accelerated in the forward shock powered by a magnetar wind pushing the ejecta launched during the merger process would interact with photons generated in the dissipating magnetar wind and emit high energy neutrinos and photons. We estimate the typical energy and fluence of the neutrinos from such a scenario. We find that $\sim$PeV neutrinos could be emitted from the shock front as long as the ejecta could be accelerated to a relativistic speed. The diffuse neutrino flux from these events, even under the most optimistic scenarios, is too low to account for the two events announced by the IceCube Collaboration, but it is only slightly lower than the diffuse flux of GRBs, making it an important candidate for the diffuse background of $\sim$PeV neutrinos. The neutron-pion decay of these events make them a moderate contributor to the sub-TeV gamma-ray diffuse background.

description: The irreversible thermodynamics of a continuous medium with magnetic dipoles predicts that a temperature gradient in the presence of magnetisation waves induces a magnetic induction field, which is the magnetic analog of the Seebeck effect. This thermal gradient modulates the precession and relaxation. The Magnetic Seebeck effect implies that magnetisation waves propagating in the direction of the temperature gradient and the external magnetic induction field are less attenuated, while magnetisation waves propagating in the opposite direction are more attenuated.

description: In this work, the linear stability of the viscous incompressible fluid flow between two parallel horizontal porous stationary plates with the assumption that there is a small constant suction at upper plate and a small constant injection at the lower plate is studied.The Navier-Stokes and continuous equations are reduced to an equation modified by the suction Reynolds number, which we call modified Orr-Sommerfeld equation. This equation is rewritten as an eigenvalue problem and is solved numerically using Matlab (Windows Version). The effect of small suction Reynolds number on the linear stability fluid flow is discussed.

Power and spherical series over real alternative *-algebras

description: We study two types of series over a real alternative $^*$-algebra $A$. The first type are series of the form $\sum_{n} (x-y)^{\punto n}a_n$, where $a_n$ and $y$ belong to $A$ and $(x-y)^{\punto n}$ denotes the $n$--th power of $x-y$ w.r.t.\ the usual product obtained by requiring commutativity of the indeterminate $x$ with the elements of $A$. In the real and in the complex cases, the sums of power series define, respectively, the real analytic and the holomorphic functions. In the quaternionic case, a series of this type produces, in the interior of its set of convergence, a function belonging to the recently introduced class of slice regular functions. We show that also in the general setting of an alternative algebra $A$, the sum of a power series is a slice regular function. We consider also a second type of series, the spherical series, where the powers are replaced by a different sequence of slice regular polynomials. It is known that on the quaternions, the set of convergence of these series is an open set, a property not always valid in the case of power series. We characterize the sets of convergence of this type of series for an arbitrary alternative $^*$-algebra $A$. In particular, we prove that these sets are always open in the quadratic cone of $A$. Moreover, we show that every slice regular function has a spherical series expansion at every point.

description: Preliminary results on particle spectra and fluctuations in inelastic p+p interactions measured by NA61/SHINE at the CERN SPS are presented and its future ion program is discussed. We also show results on the excitation functions of event-by-event particle ratio fluctuations in central Pb+Pb collisions from NA49 using a novel approach. We found a dependence of the results on phase space coverage which appears to explain the reported difference between measurements of NA49 and those of STAR in central Au+Au collisions.

description: The ESO/MPG WFI and the INT WFC wide field archives comprising 330,000 images were mined to search for serendipitous encounters of known Near Earth Asteroids (NEAs) and Potentially Hazardous Asteroids (PHAs). A total of 152 asteroids (44 PHAs and 108 other NEAs) were identified using the PRECOVERY software, their astrometry being measured on 761 images and sent to the Minor Planet Centre. Both recoveries and precoveries were reported, including prolonged orbital arcs for 18 precovered objects and 10 recoveries. We analyze all new opposition data by comparing the orbits fitted before and after including our contributions. We conclude the paper presenting Mega-Precovery, a new online service focused on data mining of many instrument archives simultaneously for one or a few given asteroids. A total of 28 instrument archives have been made available for mining using this tool, adding together about 2.5 million images forming the Mega-Archive.

Regulation of FVIII-specific immunity in Hemophilia A mice

description: The major complication of Hemophilia A treatment is the formation of inhibitors that neutralize the administered FVIII. Immune tolerance induction (ITI) is the most frequently used therapy in order to establish long-lasting tolerance towards FVIII in patients with inhibitors. However, predicting ITI success is challenging and the underlying cellular and molecular mechanisms are poorly described, thus therapy stability and duration is individualized, and might be influenced by several risk factors. Here, I demonstrate that upon successful tolerization of HemA mice, a PR8 infection in the lung triggered a systemic alteration of the inflammatory state. FVIII-specific B cells, responsible for the anti-FVIII humoral alloimmune response, are increased upon infection, while the FVIII-specific Tregs and their PD-L1 expression, induced during ITI in vivo, were reduced. Additionally, the FVIII-specific T cell compartment changed into a pro-inflammatory phenotype with an increase of FVIII-specific Th17 and Tfh cells. The inter-organ crosstalk between lung and spleen, was mediated by IFN-g, reactivating FVIII-specific B cells, which exhibited a significantly elevated IFN-gR expression. Consequently, these FVIII-specific B cells shifted their phenotype, by increasing their CD80 expression and an initiated IL-6 production. This shift contributed to a loss of the previously established tolerogenic environment towards FVIII achieved through the ITI protocol by fostering T cell dedifferentiation upon IL-6 exposure. Finally emphasizing the importance of the IL-6 signaling in tolerance disruption, the inhibition of IL-6R proved that the tolerized phenotype was restored upon application. Furthermore, other external elements such a high salt diet (HSD) did not impact the ITI outcome. Nevertheless, the HSD in wildtype mice induced elevated corticosterone levels in the bloodstream which modified the uptake behavior of splenic red pulp macrophages and seemed to promote a shift towards a pro-inflammatory phenotype. This was accompanied by a reduction of the FVIII levels in the bloodstream, disturbing the equilibrium of the FVIII homeostasis. Overall, these results may pave the wave for novel therapeutic intervention strategies to improve ITI success and the hemostatic FVIII abundance through a more detailed understanding of the interplay between FVIII, immune and tolerance responses and external factors.

description: La pandemia Covid-19 ha comportato conseguenze e trasformazioni prefigurando scenari inediti sul piano economico, sociale e personale, determinando anche nel campo della ricerca l’urgenza di esplorarne le ricadute. Il volume dà quindi conto delle indagini svolte e in corso, sin dai primi giorni del lockdown, dai docenti e dai collaboratori del Dipartimento di Scienze della Formazione dell’Università Roma Tre, toccando i temi più diversi: dalla didattica a distanza, all’università e nei diversi ordini di scuola, al futuro dei servizi di orientamento, dal lavoro socio-educativo nelle varie tipologie di servizi all’impatto della pandemia sulle comunità, dalle narrazioni ai linguaggi artistici a contrasto di quest’emergenza non solo sanitaria. Si sono così esplorate le diverse educazioni possibili, riassegnando centralità ai processi formativi e al benessere delle persone, provando a tratteggiare nuovi paradigmi e prospettive.
description: Il contributo, nel riflettere sulle conseguenze dell’emergenza sanitaria nei differenti contesti educativi, rimarca la necessità per la ripresa di incentivare e irrobustire alleanze e sinergie tra l’istituzione scolastica e gli organismi associativi presenti sui territori attraverso l’analisi di una buona pratica e cioè la sperimentazione condotta dall’associazione S.Co.S.S.E. (Soluzioni Comunicative Studi Servizi Editoriali) tra le fondatrici della Rete nazionale Educare alle differenze e che ha tra le finalità la costruzione di uno spazio pubblico aperto, partecipato e solidale, contro ogni forma di esclusione sociale. L’analisi parte dalla pubblicazione Scosse in classe, una raccolta di percorsi e strumenti trasversali dal nido alla scuola secondaria di primo grado, realizzata, per educare, attraverso i linguaggi espressivi, nello specifico quelli narrativi, alla complessità ed esplorare vissuti ed emozioni, ridisegnando spazi e relazioni e valorizzando le differenze e la dimensione della corporeità.

description: We present a synchrotron grazing incidence x-ray diffraction analysis of the domain structure and polar symmetry of highly strained BiFeO3 thin films grown on LaAlO3 substrate. We revealed the existence of periodic elastic nanodomains in the pure tetragonal-like BFO ultrathin films down to a thickness of 6 nm. A unique shear strain accommodation mechanism is disclosed. We further demonstrated that the periodicity of the nanodomains increases with film thickness but deviates from the classical Kittel's square root law in ultrathin thickness regime (6 - 30 nm). Temperature-dependent experiments also reveal the disappearance of periodic modulation above 90C due to a MC-MA structural phase transition.
