description: We evaluate the quasielastic and multinucleon contributions to the antineutrino nucleus scattering cross section and compare our results with the recent MiniBooNE data. We use a local Fermi gas model that includes RPA correlations and gets the multinucleon part from a systematic many body expansion of the $W$ boson selfenergy in the nuclear medium. The same model had been quite successful for the neutrino cross section and contains no new parameters. We have also analysed the relevance of 2p2h events for the antineutrino energy reconstruction.

description: We present chemical abundance analyses of sodium, iron-peak and neutron-capture elements for 97 kinematically selected thick disk, inner halo and outer halo stars with metallicities -3.3-1.5), differences in some of the abundance ratios among the three subsamples are identified. Specifically, the [Na/Fe], [Ni/Fe], [Cu/Fe], and [Zn/Fe] ratios in the inner and outer halo subsamples are found to be lower than those in the thick disk subsample. In contrast to what was observed for [Mg/Fe] in our previous paper, [Eu/Fe] ratios are more enhanced in the two halo subsamples rather than in the thick disk subsample. The observed distinct chemical abundances of some elements between the thick disk and inner/outer halo subsamples with [Fe/H]>-1.5 support the hypothesis that these components formed through different mechanisms. In particular, our results favor the scenario that the inner and outer halo components formed through an assembly of multiple progenitor systems that experienced various degrees of chemical enrichments, while the thick disk formed through rapid star formation with an efficient mixing of chemical elements.

description: Obwohl Mitteldeutschland ein klassisches Untersuchungsgebiet zum späten Jungpaläolithikum Europas ist, gibt es immer noch zahlreiche Inventare, zu denen wenige oder gar keine Informationen bekannt sind. Die vorliegende Arbeit prä - sentiert deshalb alle Informationen zu einer lokalen Fundstellenkonzentration, der aus dem Tal der Weißen Elster zwischen Bad Köstritz und Zeitz. Von den acht Fundkomplexen ist nur einer durch Ausgrabung entstanden, alle anderen sind durch Oberflächenaufsammlung bekannt. In sieben Inventaren gibt es daher auch jüngere Beifunde, vor allem vor - geschichtliche Silices, die in vier Fundkomplexen dominieren. Deshalb ist weder die Unterscheidung paläolithischer und postmesolithischer Silices noch die von Retusche und Kantenbeschädigung unproblematisch. Fünf Inventare umfassen nicht mehr als 100, nur drei Inventare mehr als 400 paläolithische Steinartefakte. Trotzdem lassen die Inventare eine archäostratigraphische Ansprache zu, die einen Fundniederschlag vom Magdalénien bis zum Spätpaläolithikum zeigt.
description: Although Central Germany is a classical research area regarding the late Young Palaeolithic of Europe many inventories information lack information entirely or in parts. This contribution therefore presents comprehensive information for a local concentration of sites from the valley of the Weisse Elster between Bad Köstritz and Zeitz. Only one of these eight sites has been explored by excavation, the others have come into existence by collecting surface finds. Consequently seven inventories also contain younger artefacts, especially prehistoric flints dominating in four complexes. For this reason neither the differentiation between Palaeolithic and post-Mesolithic flints nor between retouching and simple core damages is unproblematic. Five inventories comprise not more than 100, only three more than 400 Palaeolithic lithics. Nevertheless, the inventories allow an archaeo stratigraphical classification of a find record from the Magdalenian to the Late Palaeolithic.

description: A single-electron tunneling (SET) device with a nanoscale central island that can move with respect to the bulk source- and drain electrodes allows for a nanoelectromechanical (NEM) coupling between the electrical current through the device and mechanical vibrations of the island. Although an electromechanical "shuttle" instability and the associated phenomenon of single-electron shuttling were predicted more than 15 years ago, both theoretical and experimental studies of NEM-SET structures are still carried out. New functionalities based on quantum coherence, Coulomb correlations and coherent electron-spin dynamics are of particular current interest. In this article we present a short review of recent activities in this area.

description: In Lake Biwa, located in Shiga Prefecture, Japan, the overgrowth of waterweeds has become a significant environmental and human-life problem. Therefore, the waterweeds are systematically harvested and composted. In order to consider the effective use of waterweed compost for carbon neutrality and resource recycling, we clarified the characteristics of the waterweed compost by cultivation experiments with Komatsuna (Brassica rapa var. perviridis). When the waterweed compost (20%) was applied alone, the growth of plants was promoted about 1.7 times compared to a control containing the same amount of fertilizer components. However, the plant showed yellowing of leaves and a high C/N ratio, indicating obvious symptoms of nitrogen deficiency. The application of the waterweed compost (20%) with chemical fertilizer remarkably enhanced plant growth up to about 3.5 times without nitrogen deficiency compared to a control containing only chemical fertilizer. Interestingly, the coexistence of the waterweed compost and chemical fertilizer activated nitrification and diversified soil bacteria (Chao1 index, 213.0; Shannon index, 6.50) rather than the waterweed compost alone (Chao1 index, 41.3; Shannon index, 4.34). Our results indicate that the waterweed compost functions effectively as an organic fertilizer and a soil amendment, contributing to sustainable agriculture.

description: This paper deals with Prym eigenforms which are introduced previously by McMullen. We prove several results on the directional flow on those surfaces, related to complete periodicity (introduced by Calta). More precisely we show that any homological direction is algebraically periodic, and any direction of a regular closed geodesic is a completely periodic direction. As a consequence we draw that the limit set of the Veech group of every Prym eigenform in some Prym loci of genus 3,4, and 5 is either empty, one point, or the full circle at infinity. We also construct new examples of translation surfaces satisfying the topological Veech dichotomy. As a corollary we obtain new translation surfaces whose Veech group is infinitely generated and of the first kind.

description: Dry direct-seeded rice (DDSR) cultivation is expected to reduce production costs compared with transplanted rice (TPR); however, its low N use efficiency (NUE) has hindered cost reduction. We conducted DDSR field experiments for 3 years using a standard cultivar (‘Akitakomachi’) and a high-yielding cultivar (‘Yumiazusa’) grown with a single application of coated urea (CU) or split applications of normal urea (NU) to determine factors limiting yield and NUE and compared growth and yields of TPR grown in adjacent fields. DDSR yield was lower than that of TPR at comparable N levels by 11% due to low fertilizer recovery rate, crop NUE (CNUE, yield per unit N uptake), and poor grain filling by meteorological factors. Crop N uptake at maturity in DDSR was similar to or even greater than that in TPR, but poor vegetative growth in DDSR and low crop N uptake until panicle formation (PF) resulted in limited spikelet density and CNUE compared with TPR. Analysis of the N uptake pattern suggests that enhancing early leaf development can improve N uptake until PF and thus CNUE in DDSR. NU yielded as much as CU, so it can potentially reduce the cost of production because of its lower price, but the optimal N proportion and application stage in the split application needs scrutinizing. ‘Yumiazusa’ had better initial growth, CNUE, and yield than ‘Akitakomachi’ in DDSR. To leverage these traits for further yield improvements, we also need to consider suitable phenological characteristics to ensure favorable climatic conditions during the grain-filling period.

description: [Abridged] Debris disks are extrasolar analogs to the solar system planetesimal belts. The star Fomalhaut harbors a cold debris belt at 140 AU as well as evidence of a warm dust component, which is suspected of being a bright analog to the solar system's zodiacal dust. Interferometric observations obtained with the VLTI and the KIN have identified near- and mid-infrared excesses attributed to hot and warm exozodiacal dust in the inner few AU of the star. We performed parametric modeling of the exozodiacal disk using the GRaTeR radiative transfer code to reproduce the interferometric data, complemented by mid- to far-infrared measurements. A detailed treatment of sublimation temperatures was introduced to explore the hot population at the sublimation rim. We then used an analytical approach to successively testing several source mechanisms. A good fit to the data is found by two distinct dust populations: (1) very small, hence unbound, hot dust grains confined in a narrow region at the sublimation rim of carbonaceous material; (2) bound grains at 2 AU that are protected from sublimation and have a higher mass despite their fainter flux level. We propose that the hot dust is produced by the release of small carbon grains following the disruption of aggregates that originate from the warm component. A mechanism, such as gas braking, is required to further confine the small grains for a long enough time. In situ dust production could hardly be ensured for the age of the star, so the observed amount of dust must be triggered by intense dynamical activity. Fomalhaut may be representative of exozodis that are currently being surveyed worldwide. We propose a framework for reconciling the hot exozodi phenomenon with theoretical constraints: the hot component of Fomalhaut is likely the tip of the iceberg since it could originate from a warm counterpart residing near the ice line.

description: Binomial edge ideals IG of a graph G were introduced by [4]. They found some classes of graphs G with the property that IG is a Cohen-Macaulay ideal. This might happen only for few classes of graphs. A certain generalization of being Cohen-Macaulay, named approximately Cohen-Macaulay, was introduced by S. Goto in [3]. We study classes of graphs whose binomial edge ideal are approximately Cohen-Macaulay. Moreover we use some homological methods in order to compute their Hilbert series.

We consider both ordered and disordered phases which differ in atomic order in the Te-Br sublattice. On the basis of relativistic ab-initio calculations, we show that the ordered BiTeBr is energetically preferable as compared with the disordered one. We demonstrate that both Te- and Br-terminated surfaces of the ordered BiTeBr hold surface states with a giant spin-orbit splitting. The Te-terminated surface-state spin splitting has the Rashba-type behavior with the coupling parameter α_R ~ 2 eVÅ.

Various parameters (density, grain growth, grain size distribution) of the alumina ceramics, sintered at two typical temperatures 1400°C and 1700°C, are investigated. Quantitative textural and structural analysis, carried out using a combination of Electron Back Scattering Diffraction (EBSD) and X-ray diffraction (XRD), are represented in the form of mapping, and pole figures. The mechanical properties of these textured alumina ceramics include high elastic modulus and hardness value with high anisotropic nature, opening the door for a large range of applications

Uniqueness of the direct decomposition of toric manifolds

Subjects: subject: Algebraic Topology (math.AT)

description: In this paper, we study the uniqueness of the direct decomposition of a toric manifold. We first observe that the direct decomposition of a toric manifold as \emph{algebraic varieties} is unique up to order of the factors. An algebraically indecomposable toric manifold happens to decompose as smooth manifold and no criterion is known for two toric manifolds to be diffeomorphic, so the unique decomposition problem for toric manifolds as \emph{smooth manifolds} is highly nontrivial and nothing seems known for the problem so far. We prove that this problem is affirmative if the complex dimension of each factor in the decomposition is less than or equal to two. A similar argument shows that the direct decomposition of a smooth manifold into copies of $\mathbb{C}P^1$ and simply connected closed smooth 4-manifolds with smooth actions of $(S^1)^2$ is unique up to order of the factors.

description: The evolution of white dwarfs is a simple gravothermal process. This means that their luminosity function, i.e. the number of white dwarfs per unit bolometric magnitude and unit volume as a function of bolometric magnitude, is a monotonically increasing function that decreases abruptly as a consequence of the finite age of the Galaxy. The precision and the accuracy of the white dwarf luminosity functions obtained with the recent large surveys together with the improved quality of the theoretical models of evolution of white dwarfs allow to feed the hope that in a near future it will be possible to reconstruct the history of the different Galactic populations.

description: Proplyds are photodissociation region (PDR)-like cometary cocoons around young stars which are thought to originate through photo-evaporation of the central protoplanetary disk by external UV radiation from the nearby OB stars. This letter presents spatially resolved mid-infrared imaging and spectroscopy of the proplyd HST10 obtained with the VLT/VISIR instrument. These observations allow us to detect Polycyclic Aromatic Hydrocarbons (PAH) emission in the proplyd photodissociation region and to study the general properties of PAHs in proplyds for the first time. We find that PAHs in HST10 are mostly neutral and at least 50 times less abundant than typical values found for the diffuse ISM or the nearby Orion Bar. With such a low PAH abundance, photoelectric heating is significantly reduced. If this low abundance pertains also to the original disk material, gas heating rates could be too low to efficiently drive photoevaporation unless other processes can be identified. Alternatively, the model behind the formation of proplyds as evaporating disks may have to be revised.

description: This article addresses the issue of representing electroencephalographic (EEG) signals in an efficient way. While classical approaches use a fixed Gabor dictionary to analyze EEG signals, this article proposes a data-driven method to obtain an adapted dictionary. To reach an efficient dictionary learning, appropriate spatial and temporal modeling is required. Inter-channels links are taken into account in the spatial multivariate model, and shift-invariance is used for the temporal model. Multivariate learned kernels are informative (a few atoms code plentiful energy) and interpretable (the atoms can have a physiological meaning). Using real EEG data, the proposed method is shown to outperform the classical multichannel matching pursuit used with a Gabor dictionary, as measured by the representative power of the learned dictionary and its spatial flexibility. Moreover, dictionary learning can capture interpretable patterns: this ability is illustrated on real data, learning a P300 evoked potential.

description: We report on the development of a prototype integrated receiver front-end that combines all conversions from RF to baseband, from analog to digital, and from copper to fiber into one compact assembly, with the necessary gain and stability suitable for radio astronomy applications. The emphasis in this article is on a novel digital data link over optical fiber which requires no formatting in the front-end, greatly reducing the complexity, bulk, and power consumption of digital electronics inside the antenna, facilitating its integration with the analog components, and minimizing the self-generated radio-frequency interference (RFI) which could leak into the signal path. Management of the serial data link is performed entirely in the back-end based on the statistical properties of signals with a strong random noise component. In this way, the full benefits of precision and stability afforded by conventional digital data transmission are realized with far less overhead at the focal plane of a radio telescope.

With this scheme, we demonstrate that the number of atoms in a pure BEC can be greatly boosted by a factor of 5 in a simple setup that includes a single-beam optical trap or a crossed optical trap. This optimal scheme avoids technical challenges associated with some all-optical BEC methods, and can be applied to other optically trappable atomic species. In addition, we find a good agreement between our theoretical model and data. The upper limit for the efficiency of evaporative cooling in all-optical BEC approaches is also discussed.

description: This work investigates the dose-response curves of GAFCHROMIC EBT, EBT2, and EBT3 radiochromic films using synchrotron-produced monochromatic x-ray beams. EBT2 film is being utilized for dose verification in photoactivated Auger electron therapy at the Louisiana State University CAMD synchrotron facility. Monochromatic beams of 25, 30, and 35 keV were generated on the tomography beamline at CAMD. Ion chamber depth-dose measurements were used to determine the dose delivered to films irradiated at depths from 0.7 to 8.5 cm in a 10x10x10-cm3 PMMA phantom. AAPM TG-61 protocol was applied to convert measured ionization into dose. Films were digitized using an Epson 1680 Professional flatbed scanner and analyzed using the net optical density (NOD) derived from the red channel. A dose-response curve was obtained at 35 keV for EBT film, and at 25, 30, and 35 keV for EBT2 and EBT3 films. Calibrations of films for 4 MV x-rays were obtained for comparison using a radiotherapy accelerator at Mary Bird Perkins Cancer Center. The sensitivity (NOD per unit dose) of EBT film at 35 keV relative to that for 4-MV x-rays was 0.73 and 0.76 for doses 50 and 100 cGy, respectively. The sensitivity of EBT2 film at 25, 30, and 35 keV relative to that for 4-MV x-rays varied from 1.09 - 1.07, 1.23 - 1.17, and 1.27 - 1.19 for doses 50 - 200 cGy, respectively. For EBT3 film the relative sensitivity was within 3% of unity for all three monochromatic x-ray beams. EBT and EBT2 film sensitivity showed strong energy dependence over an energy range of 25 keV - 4 MV, although this dependence becomes weaker for larger doses. EBT3 film shows weak energy dependence, indicating that it would be a better dosimeter for kV x-ray beams where beam hardening effects can result in large changes in the effective energy.

description: We demonstrate the one-to-one correspondence between reparametrization invariant effective actions for relativistic p-branes in flat target space and effective actions for transverse brane perturbations with non-linearly realized Poincaré symmetry. Starting with an action with non-linearly realized symmetry we construct the corresponding reparametrization invariant action by introducing Stückelberg fields. They combine with the transverse modes to form a Lorentz vector. The manifest Lorentz symmetry of the reparametrization invariant action follows directly from the non-linearly realized Lorentz symmetry of the initial action in terms of the physical modes.

description: The UMass Amherst Libraries host "Daniel Ellsberg: A Life in Truth," a physical and digital exhibit drawing from activist and truth teller Daniel Ellsberg’s vast collection of documents, photographs, and artifacts. The Robert S. Cox Special Collections and University Archives Research Center acquired the collection in 2019. The exhibit is located in two locations in the W. E. B. Du Bois Library until September 2022.

The exhibit documents Ellsberg’s 90-year life as an academic, activist, defendant, government contractor, Marine, pianist, Vietnam observer, and whistleblower. From his middle-class upbringing in the suburbs of Detroit, Michigan in the 1930s, to his education at the Cranbrook School, Harvard University, and the Marines; his work as a nuclear analyst at RAND; research for the U.S. Defense Department in Vietnam; and transformation to full-time activist following his release of the Pentagon Papers in 1971; the exhibit illustrates the cinematic sweep of Ellsberg’s life in fine detail.

Selected digitized versions of material from the exhibit are also available via the Ellsberg Archive Project website, where it will be accessible to the public beyond its physical exhibit space.

description: We present a 2D study of the internal extinction on (sub)kiloparsec scales of a sample of local (z<0.1) (U)LIRGs, based on near-infrared Pa_a, Br_d, and Br_g line ratios, obtained with VLT-SINFONI integral-field spectroscopy. The 2D extinction (Av) distributions of the objects, map regions of ~3x3 kpc (LIRGs) and ~12x12 kpc (ULIRGs), with average angular resolutions (FWHM) of ~0.2 kpc and ~0.9 kpc, respectively. The individual Av galaxy distributions indicate a very clumpy dust structure already on sub-kiloparsec scales, with values (per spaxel) ranging from Av ~ 1 to 20 mag in LIRGs, and from Av ~ 2 to 15 mag in ULIRGs. As a class, the median values of the distributions are Av=5.3 mag and Av=6.5 mag for the LIRG and ULIRG subsamples, respectively. We evaluated the effects of the galaxy distance in the measurements of the extinction as a function of the linear scale (in kpc) of the spaxel (i.e. due to the limited angular resolution of the observations). If the distribution of the gas/dust and star-forming regions in local LIRGs (63 Mpc, 40 pc/spaxel on average) is the same for galaxies at greater distances, the observed median Av values based on emission line ratios would be a factor ~0.8 lower at the average distance of our ULIRG sample (328 Mpc, 0.2 kpc/spaxel), and a factor ~0.67 for galaxies located at distances of more than 800 Mpc (0.4 kpc/spaxel). This distance effect would have implications for deriving the intrinsic extinction in high-z star-forming galaxies and for subsequent properties such as star formation rate, star formation surface density, and KS- law, based on H_alpha line fluxes. If local LIRGs are analogues of the main-sequence star-forming galaxies at cosmological distances, the extinction values (Av) derived from the observed emission lines in these high-z sources would need to be increased by a factor 1.4 on average.

description: We discuss an ensemble of topological solitons -- instanton-dyons and antidyons - in SU(2) pure gauge theory at finite temperatures above and below the deconfinement phase transition temperature. The main focus is on the combined effect of this ensemble on the so called effective holonomy potential, which drives the confinement/deconfinement phase transition. Using a simple model with excluded volume and lattice data on caloron density we find that repulsive part of the potential is robust enough to induce the phase transition at the right temperature. Model's predictions -- the holonomy potential, electric and magnetic screening masses as a function of T -- are in qualitative agreement with the available lattice data. Further predictions are densities of various dyon types as a function of temperature: while some lattice measurements of them had been made, much more accurate data are needed to test these predictions.

description: The UMass Amherst Libraries hosts an exhibit, “Unseen Labor,” can be viewed through May 2022, in the Science and Engineering Library in Lederle Lowrise, Floor 2, at the University of Massachusetts Amherst. The exhibit is a library community-organizing art project created by UMass Amherst metadata librarian Ann Kardos, and consists of cross stitch and embroidery pieces that share stories about libraries, the theme of unseen labor, the work that metadata librarians do, projects they are proud of, and more. The exhibit represents approximately 60 creators from a wide variety of libraries: academic, public, museum libraries, and archives, from all over the U.S., Canada, and the United Kingdom.

Metadata work is not typically seen as creative work, but rather work that is guided by national standards, best practices, policies, and guidelines in order to produce and maintain standard records for library resources that can be shared between institutions and vendors.

Metadata librarians create and maintain millions of library resources for patrons, with whom they may rarely (if ever) interact, and they provide valuable backend support for their public-facing colleagues. The project asked library metadata creators to examine stories and experiences that would center their unseen labor, both physical and emotional. A companion eBook exhibition catalogue will be available.

Ann Kardos has been a metadata librarian at the University of Massachusetts Amherst since 2017, where she works as part of a small team of dedicated individuals supporting access to approximately seven million records in the Five College Catalog. Kardos learned how to cross stitch as a child and took it up again during the pandemic for stress relief. In November 2021, she had an original embroidery piece on display at the National Liberty Museum in Philadelphia, as part of the Badass Herstory exhibit curated by artist and activist Shannon Downey, who goes by the name Badass Cross Stitch.

Bose-Einstein condensation in the three-sphere and the infinite slab: analytical results

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We study the finite size effects on Bose-Einstein condensation (BEC) of an ideal non-relativistic Bose gas in the three-sphere (spatial section of the Einstein universe) and in a partially finite box which is infinite in two of the spatial directions (infinite slab). Using the framework of grand-canonical statistics, we consider the number of particles, the condensate fraction and the specific heat. After obtaining asymptotic expansions for large system size, which are valid throughout the BEC regime, we describe analytically how the thermodynamic limit behaviour is approached. In particular, in the critical region of the BEC transition, we express the chemical potential and the specific heat as simple explicit functions of the temperature, highlighting the effects of finite size. These effects are seen to be different for the two different geometries. We also consider the Bose gas in a one-dimensional box, a system which does not possess BEC in the sense of a phase transition even in the infinite volume limit.

title: L’apprendimento linguistico tra parametri e transfer
Creators: name: Baldi, Benedetta
Publisher: name: Firenze University Press
Year: 2019

description: This article investigates the relation between L1 and L2 in the light of the transfer phenomena. More precisely a revision of the UG notion and parameter is proposed on the basis of the mentalist model proposed within the bio-linguistic program in some recent works by Chomsky. The idea being discussed here is that parameterization is a phenomenon associated with the externalization of linguistic expressions in terms of lexical and morpho-syntactic properties, on the basis of the basic properties of language. The notion of language coincides with a specialized cognitive capability, i.e. the combinatory mechanism (Merge), whereas its application implies the interaction with the external interpretive systems, namely sensory-motor and conceptual-intentional systems. As a consequence, transfer, as depending on the morpho-lexical organization of languages, is a mechanism that does not call into question the cognitive nature of language. On the contrary, we have to look at transfer as the natural solution for the acquisition of L2.

This yields a geometric q-character formula for tensor products of Kirillov-Reshetikhin modules. In simply laced type this formula extends Nakajima's formula for q-characters of standard modules in terms of homology of graded quiver varieties.

Disorder-induced cubic phase in Fe$_2$-based Heusler alloys

description: Based on first-principles electronic structure calculations, we analyze the chemical and magnetic mechanisms stabilizing the cubic phase in Fe$_2$-based Heusler materials, which were previously predicted to be tetragonal when being chemically ordered. In agreement with recent experimental data, we found that these compounds crystallize within the so-called "inverted" cubic Heusler structure perturbed by a certain portion of the intrinsic chemical disorder. Understanding these mechanisms is a necessary step to guide towards the successful future synthesis of the stable Fe$_2$-based tetragonal phases, which are very promising candidates for the fabrication of rare-earth-free permanent magnets.
