description: Sulfur (S) and Nitrogen (N) metabolisms in plants are interacted and it is known that S deficiency decrease N absorption and metabolism. In leguminous plants S deficiency also decreases N2 fixation by rhizobia in the nodules. Deep placement of a controlled-release N fertilizer is a good method to provide nitrogen to soybean without inhibiting N2 fixation; thus, it was hypothesized that this method is able to provide nitrogen effectively to sulfur-deficient soybean plants. In this study effects of deep placement of coated urea on S-N physicological interaction, growth and productivity in soybean plants were examined using pot experiments. Soybean plants were grown with sulfate concentrations of 30, 100, or 1000 μM, with or without deep placement of coated urea. Shoot weights at the developing stage were not affected by S deficiency. SPAD values of leaves during the flowering stage decreased with S deficiency and increased with the deep placement of coated urea. S deficiency decreased seed weight per plant at the harvesting stage, but this decrease was attenuated by the deep placement of coated urea. N and S content in shoots at the developing stage increased with the deep placement of coated urea, whereas in seeds, only the N content increased. N2 fixation activity based on the relative ureide-N content in xylem sap indicated that the deep placement of coated urea did not inhibit N2 fixation activity at the early flowering stage. Without deep placement of coated urea, the relative ureide-N content decreased under S deficiency at the seed filling stage. These results suggest that the deep placement of coated urea is an efficient method to supply N to support soybean yield under S deficiency.

description: We report a simple, rapid, and quantitative wide-field technique to measure the optical extinction $σ_{\rm ext}$ and scattering $σ_{\rm sca}$ cross-section of single nanoparticles using wide-field microscopy enabling simultaneous acquisition of hundreds of nanoparticles for statistical analysis. As a proof of principle, we measured nominally spherical gold nanoparticles of 40\,nm and 100\,nm diameter and found mean values and standard deviations of $σ_{\rm ext}$ and $σ_{\rm sca}$ consistent with previous literature. Switching from unpolarized to linearly polarized excitation, we measured $σ_{\rm ext}$ as a function of the polarization direction, and used it to characterize the asphericity of the nanoparticles. The method can be implemented cost-effectively on any conventional wide-field microscope and is applicable to any nanoparticles.

description: Disease control is of paramount importance in public health with infectious disease extinction as the ultimate goal. Although diseases may go extinct due to random loss of effective contacts where the infection is transmitted to new susceptible individuals, the time to extinction in the absence of control may be prohibitively long. Thus intervention controls, such as vaccination of susceptible individuals and/or treatment of infectives, are typically based on a deterministic schedule, such as periodically vaccinating susceptible children based on school calendars. In reality, however, such policies are administered as a random process, while still possessing a mean period. Here, we consider the effect of randomly distributed intervention as disease control on large finite populations. We show explicitly how intervention control, based on mean period and treatment fraction, modulates the average extinction times as a function of population size and rate of infection spread. In particular, our results show an exponential improvement in extinction times even though the controls are implemented using a random Poisson distribution. Finally, we discover those parameter regimes where random treatment yields an exponential improvement in extinction times over the application of strictly periodic intervention. The implication of our results is discussed in light of the availability of limited resources for control.

description: We examine the milli-charged dark matter scenario from a string theory perspective. In this scenario, kinetic and mass mixings of the photon with extra U(1) bosons are claimed to give rise to small electric charges, carried by dark matter particles, whose values are determined by continuous parameters of the theory. This seems to contradict folk theorems of quantum gravity that forbid the existence of irrational charges in theories with a single massless gauge field. By considering the underlying structure of the U(1) mass matrix that appears in type II string compactifications, we show that milli-charges arise exclusively through kinetic mixing, and require the existence of at least two exactly massless gauge bosons.

description: Rice absorbs radiocesium dissolved in soil solution. However, quantitative determination of dissolved radiocesium is difficult because large volume of water should be collected from paddy soil. We investigated whether a sheet capable of effectively trapping cesium (zinc-substituted Prussian blue (ZnPB) sheet) can be used to evaluate the level of dissolved 137Cs to be absorbed by rice. A new device equipped with ZnPB sheet was invented to trap only radiocesium dissolved in soil solution, which is passed through a membrane filter covering the ZnPB sheet. A rice pot-culture experiment using three paddy soils with different 137Cs concentrations and physico-chemical properties collected from Fukushima Prefecture was conducted under different fertilization or rice-planting treatments. The results showed that 137Cs concentration in brown rice was positively correlated with the 137Cs concentration in soil solution with a contribution ratio of regression R2 of 0.91 and a p value less than 0.01, and also with the 137Cs-trapping rate by ZnPB sheet (amount of 137Cs trapped by ZnPB sheet per unit area of sheet and unit time) buried in soil with a R2 value of 0.89 and a p value less than 0.01. Moreover, field-cropping experiments conducted at the three paddy fields under conventional agricultural practices showed positive correlation between the 137Cs concentration in brown rice and 137Cs-trapping rate by ZnPB sheet. Both the pot and field experiments showed that the 2 weeks of the early stage of rice growth is appropriate as the ZnPB buried period because K additive fertilization is still in time to restrict 137Cs uptake by rice plant, and because the highest 137Cs-trapping rates of the ZnPB plate as compared with the following periods and high R2 values of those regression curves. . The proposed method might be used to roughly evaluate the vulnerability of soil to 137Cs transfer to rice and to identify the area in which effective countermeasure should be applied intensively.

description: We show that if a Barker sequence of length $n>13$ exists, then either $n=3979201339721749133016171583224100$, or $n > 4\cdot10^{33}$. This improves the lower bound on the length of a long Barker sequence by a factor of nearly 2000. We also obtain 18 additional integers $n<10^{50}$ that cannot be ruled out as the length of a Barker sequence, and find more than 237000 additional candidates $n<10^{100}$. These results are obtained by completing extensive searches for Wieferich prime pairs and using them, together with a number of arithmetic restrictions on $n$, to construct qualifying integers below a given bound. We also report on some updated computations regarding open cases of the circulant Hadamard matrix problem.

description: This paper proposes a new methodology to automatically build semantic hierarchies suitable for image annotation and classification. The building of the hierarchy is based on a new measure of semantic similarity. The proposed measure incorporates several sources of information: visual, conceptual and contextual as we defined in this paper. The aim is to provide a measure that best represents image semantics. We then propose rules based on this measure, for the building of the final hierarchy, and which explicitly encode hierarchical relationships between different concepts. Therefore, the built hierarchy is used in a semantic hierarchical classification framework for image annotation. Our experiments and results show that the hierarchy built improves classification results. Ce papier propose une nouvelle methode pour la construction automatique de hierarchies semantiques adaptees a la classification et a l'annotation d'images. La construction de la hierarchie est basee sur une nouvelle mesure de similarite semantique qui integre plusieurs sources d'informations: visuelle, conceptuelle et contextuelle que nous definissons dans ce papier. L'objectif est de fournir une mesure qui est plus proche de la semantique des images. Nous proposons ensuite des regles, basees sur cette mesure, pour la construction de la hierarchie finale qui encode explicitement les relations hierarchiques entre les differents concepts. La hierarchie construite est ensuite utilisee dans un cadre de classification semantique hierarchique d'images en concepts visuels. Nos experiences et resultats montrent que la hierarchie construite permet d'ameliorer les resultats de la classification.

description: Azorhizobium caulinodans ORS571 is a rhizobium of the tropical legume Sesbania rostrata. This bacterium possesses the reb operon, which is associated with pathogenic R-bodies. To establish symbiosis with host plants, the expression of reb operon is suppressed at a low level by multiple regulators, such as PraR transcription factor and Lon protease. The reb operon is highly expressed in the presence of 2-oxoglutarate at temperatures lower than the optimum growth temperatures (37–38°C). 2-oxoglutarate has been found to inhibit the binding of PraR to the promoter region of the reb operon, but it is still unclear how temperature effects reb operon expression. Therefore, the purpose of our research is to clarify the temperature-depending expression mechanism. In this study, we found that PenR, which is a LysR-type transcriptional regulator of a class A β-lactamase gene (penA), is involved in reb operon expression. The reb operon of the praR mutant was highly expressed at 37°C, but not at 38°C, while the reb operon of the praR penR mutant was highly expressed even at 38°C. We also found that the expression of penA is temperature-responsive and under the control of Lon protease. penA of the wild type (WT) strain was more highly expressed at higher growth temperatures in the range of 25°C to 41°C, and the expression levels of penA in the lon mutant were lower than those in the WT strain at any growth temperatures. The penA of the penR mutant was hardly expressed irrespective of growth temperatures. Electrophoretic mobility shift assay, using His6-tagged PenR, revealed PenR bound to the promoter region of penA, but not to that of the reb operon. From these results, it was concluded that, in response to temperature, PenR represses the expression of the reb operon in an indirect manner, and induces penA in a direct manner, respectively.

description: Azorhizobium caulinodans ORS571 is a microsymbiont of the tropical legume Sesbania rostrata. This bacterium induces nodules on the stems and roots of host plants, and fixes nitrogen in the host cells within such nodules. It is also an endophytic bacterium of some non-leguminous plants, such as Arabidopsis thaliana, rice, wheat, and tomato. It is known that this bacterium colonizes in the intercellular spaces and xylems of the roots of A. thaliana plants, but these observations were not conducted under completely nitrogen-free conditions. In this study, in which A. thaliana plants were inoculated with A. caulinodans on nitrogen-free medium, it was found that A. caulinodans promoted the growth of the A. thaliana plants, however, the promotion was not caused by nitrogen fixation. Detailed observations revealed that A. caulinodans intercellularly and intracellularly infected not only the roots but also almost the whole bodies of the A. thaliana plants, except for the stems. In the leaves, infection was frequently observed not only in the stomata and intercellular spaces of the mesophyll cells, but also in the guard cells and mesophyll cells. Interestingly, chloroplasts were also infected with A. caulinodans. In the flowers, A. caulinodans was detected in the pollen cells, in the stigma and the center of the style, and in the space around the ovule in the ovary. This suggests that A. caulinodans colonizes the inside of ovaries via pollen tubes. Taken together, it can be said that this bacterium is more likely to infect A. thaliana plants in nitrogen deficient conditions than in nitrogen sufficient conditions. The findings herein are thought to be the basis for the use of A. caulinodans inoculation for the enhancement of plant growth in oligotrophic conditions.

description: We present experimental evidence of the successful closed-loop optimization of the dynamics of cold atoms in an optical lattice. We optimize the loading of an ultracold atomic gas minimizing the excitations in an array of one-dimensional tubes (3D-1D crossover) and we perform an optimal crossing of the quantum phase-transition from a Superfluid to a Mott-Insulator in a three-dimensional lattice. In both cases we enhance the experiment performances with respect to those obtained via adiabatic dynamics, effectively speeding up the process by more than a factor three while improving the quality of the desired transformation.

description: Auf den Punkt ...
Die Erhöhung der personellen Vielfalt gilt für viele Unternehmen als wegweisende Strategie, um einem drohenden Fachkräftemangel zu begegnen. In High-Tech-Bereichen wie der Technikentwicklung treffen diese Bemühungen aber häufig auf ausgeprägte Hochleistungskulturen, die für die spezifischen Bedürfnisse und Leistungsvoraussetzungen neuer Beschäftigtengruppen kaum Spielraum lassen.
Im Rahmen des BMBF-geförderten Forschungsprojekts pinowa wurde untersucht, inwieweit wegen mangelnder Lebensphasenorientierung wertvolle Arbeitskraftpotenziale hochqualifizierter Beschäftigter unzureichend erschlossen oder überbeansprucht werden, was zu gesundheitlichen Folgeschäden bei diesen Beschäftigten führen kann.
Solche beanspruchungskritischen Episoden sind u.a. Phasen erster Verantwortungsübernahme oder Phasen des Zusammenfallens von Karriereschritten und Familiengründung. Auch Beschäftigte mit knappem Spezial-Knowhow oder mit gesundheitlichen und familiären Krisen sind häufig in beanspruchungskritischen Lebensepisoden.
Dagegen konnten keine erhöhten Beanspruchungswerte gefunden werden für die in vielen Unternehmen unterstützten Episoden beim Berufseinstieg, in der Familiengründungsphase und vor dem Renteneintritt.
Die Befunde deuten darauf hin, dass Unternehmen teilweise heute schon lebensphasensensibel agieren. Diese Orientierung geht jedoch offenbar eher mit einer Belastungsverschiebung anstelle einer vorausschauenden Beschäftigungspolitik und Arbeitsgestaltung einher.

description: The 2030 Agenda was promulgated for the Sustainable Develop Goals (SDGs), which consist of 17 goals created to eradicate poverty and realize a more sustainable world. Among the goals, soil science can contribute significantly toward achieving zero hunger (#2), implementing climate action (#13), bettering life on land (#15), among others. Paddy fields are important sustainable agro-ecosystems for rice (Oryza sativa) production, and rice is the staple food for more than 2 billion people worldwide. Paddy rice is produced mainly in East, South, and Southeast Asia, in region with a monsoon climate. Paddy soils are unique, as they are mostly managed under waterlogged conditions during the rice-growing season. Nitrogen (N) is one of the most important nutrients for many crops, including rice. Some potential sustainable soil management methods are suggested to meet the SDGs, especially in paddy fields and wetlands in East, South, and Southeast Asia, based on current achievements, including N mineralization analysis, soil microbial analysis, and greenhouse gas measurements, to predict soil fertility and effective environmental management practices in the future. One such example of sustainable soil management practice is the amendment of silicate fertilizer produced from steel-making sludge that reduced methane emission from paddy fields (3%–50%) and increased the rice yield in Vietnam.

description: Pregnancy is a phenomenon which can create psychological, cognitive, emotional and communicative problems for the pregnant women in case of insufficient attention. Therefore the present study was conducted to analyze structural equations in the relationship of marital conflicts and affective security with perceived stress and pregnancy worries and biologicla indexes with the mediation of psychological wellbeing in pregnant women. The research method was descriptive in correlational and structural equations type. The statistical population of this study included pregnant women who attended women and delivery clinics and the hospital in the town of Ramsar from January to March of 2018-19. The research sample included 300 pregnant women who were selected through available sampling method. The applied instruments included marital conflict questionnaire (Sanaei et.al, 2000), affective security scale (Cordova, Gee, Warren, 2005), perceived stress questionnaire (Cohen & al, 1983), pregnancy worries questionnaire (Alderdice, Lynn, 2011) and psychological wellbeing questionnaire (Ryff, 1996). The data analysis was conducted via Pearson correlation and structural equation methods after collecting the questionnaires. The results showed that there is a significant relationship between the variables (p<0.001). Moreover, the mediation role of psychological wellbeing was proved in the relationship of marital conflicts and affective security with perceived stress and pregnancy worries and biological indexes in pregnant women. Regarding the mediation role of psychological wellbeing, it is necessary to provide and use a training package of psychological wellbeing for the women to improve affective security and biological indexes and decrease marital conflicts, perceived stress and pregnancy worries in the pregnant women.

description: We point out that there is a problem with the definition of homological critical value (as defined in the widely cited paper \cite{stability} by Cohen-Steiner, Edelsbrunner and Harer). Under that definition, the critical value lemma of \cite{stability} in fact fails. We provide several counterexamples and a definition (due to Bubenik and Scott \cite{categorification}) we feel should be preferred and under which the critical value lemma does indeed hold. One of the counterexamples we have found is a height function on a compact smooth manifold. In the end we prove that, despite all this, a modified version of the critical value lemma remains valid under the original definition.

description: Arbuscular mycorrhizal (AM) fungi is expected to be utilized in low input agriculture for their function to supply nutrients and water to host plants. AM fungal inoculum has been provided, but it has been known that their effect is context dependent. To clarify the factors that determine the effect of AM fungal inoculation to forage corn, a pot experiment was conducted using different indigenous AM fungal infection potential that evaluated with a modified infection unit method. Because we hypothesized that low indigenous AM fungal infection potential would be required to obtain significant inoculation effect, we prepared soils with different indigenous AM fungal infection potential by mixing sterile and non-sterile soils with different ratio. AM fungal colonization of non-inoculated series were increased with increase of indigenous AM fungal infection potential. Inoculation effect to increase of AM fungal colonization to corn root was generally larger in soils with low indigenous AM fungal infection potential and with low phosphorus (P) level, however, the effect was not very prominent in the soil with moderate P levels. Plant growth and plant P uptake showed similar trend with AM fungal colonization, i.e., enhanced P uptake and increase in plant dry matter were obtained when change in AM fungal colonization was larger. Therefore, low indigenous AM fungal infection potential would be required but not a sufficient condition to obtain AM fungal inoculation effect to forage corn.

description: (Abrigded) Observations of galaxies up to z 2 show a tight correlation between far-infrared and radio continuum emission. We explain the far-infrared - radio continuum correlation by relating star formation and magnetic field strength in terms of turbulent magnetic field amplification, where turbulence is injected by supernova explosions from massive stars. We calculate the expected amount of turbulence in galaxies based on their star formation rates, and infer the expected magnetic field strength due to turbulent dynamo amplification. We estimate the timescales for cosmic ray energy losses via synchrotron emission, inverse Compton scattering, ionization and bremsstrahlung emission, probing up to which redshift strong synchrotron emission can be maintained. We find that the correlation between star formation rate and magnetic field strength in the local Universe can be understood as a result of turbulent magnetic field amplification. If the typical gas density in the interstellar medium increases at high z, we expect an increase of the magnetic field strength and the radio emission, as indicated by current observations. Such an increase would imply a modification of the far-infrared - radio correlation. We expect a breakdown when inverse Compton losses start dominating over synchrotron emission. For a given star formation surface density, we calculate the redshift where the breakdown occurs, yielding z (Sigma_SFR/0.0045 M_solar kpc^{-2} yr^{-1})^{1/(6-alpha/2)}. In this relation, the parameter αdescribes the evolution of the characteristic ISM density in galaxies as (1+z)^α. Both the possible raise of the radio emission at high redshift and the final breakdown of the far-infrared -- radio correlation at a critical redshift will be probed by the Square Kilometre Array (SKA) and its pathfinders, while the typical ISM density in galaxies will be probed with ALMA.

description: Relativistic electromagnetic penetration behavior is reexamined in the relativistic transparency region. The interaction is modeled by the relativistic hydrodynamic equations coupled with the full system of Maxwell equations, which are solved by a fully implicit energy-conserving numerical scheme. For the first time, we have studied the penetration behavior through ultra-short circularly polarized and linearly polarized laser pulses interaction with over-dense plasmas. It is shown that for the ultra-short circularly polarized laser penetration occurs through a soliton like behavior, which is quite consistent with the existing studies. However, we have found that the ultra-short linearly polarized laser penetrates through a breather like behavior, and there is an energy transition mechanism with a frequency $2ω_0$ between the penetrated breather like structure and the background plasmas. A qualitative interpretation has been given to describe this mechanism of energy exchange.

description: The Similarity Renormalization Group (SRG) is used to soften interactions for ab initio nuclear structure calculations by decoupling low- and high-energy Hamiltonian matrix elements. The substantial contribution of both initial and SRG-induced three-nucleon forces requires their consistent evolution in a three-particle basis space before applying them to larger nuclei. While in principle the evolved Hamiltonians are unitarily equivalent, in practice the need for basis truncation introduces deviations, which must be monitored. Here we present benchmark no-core full configuration calculations with SRG-evolved interactions in p-shell nuclei over a wide range of softening. These calculations are used to assess convergence properties, extrapolation techniques, and the dependence of energies, including four-body contributions, on the SRG resolution scale.

description: La situazione emergenziale ha comportato la necessità di riflettere con urgenza sui rapporti tra scuola e famiglia che caratterizzano il sistema di istruzione e formazione in Italia.  La progettazione di una nuova idea di scuola da intendersi come presidio di prossimità e risorsa resiliente implica l’approfondimento e la comprensione delle dinamiche tra scuola e famiglia mediante linee dedicate di ricerca educativa. Il contributo presenta gli esiti di una indagine esplorativa locale sviluppata in continuità con la ricerca nazionale condotta dalla Società Italiana di Ricerca Didattica (SIRD) “Sulle modalità di didattica a distanza adottate nelle scuole italiane nel periodo di emergenza Covid-19”. L’indagine ha avuto come principale obiettivo quello di approfondire la corresponsabilità educativa tra scuola e famiglia durante il periodo emergenziale che ha richiesto l’attivazione della didattica a distanza nelle scuole, focalizzando l’attenzione su una scuola primaria in cui sono stati coinvolti sia docenti sia genitori, attraverso la rilevazione di dati quantitativi e qualitativi, al fine di triangolare i punti di vista. I principali esiti confermano l’importanza di stabilire rapporti di fiducia, di corresponsabilità e di solidarietà tra scuola, famiglia e comunità territoriale al fine di costruire ecosistemi estesi in grado di contrastare le situazioni di crisi e di affrontare quelle di incertezza.

description: Amid technological convergence and the proliferation of new digital distribution methods, at-home fitness devices and fitness media have entered the cultural mainstream. However, fitness media companies like Peloton, Mirror, and Tonal, as quasi-television producers and distributors, have yet to be contextualized within critical media and cultural studies. Leveraging press coverage, interface and hardware analysis, and marketing paratexts, this paper turns to television’s cultural and economic history to consider the continuities and changes concerning visual media’s place within the domestic sphere and the economic conditions that have led fitness companies to venture into media production. Ultimately, this research concludes that home fitness technologies and their associated marketing work through long-held cultural anxieties regarding surveillance and technology with the home. This paper also updates critical theory to argue that these new media devices have oriented users as information-age consumers of digital products and have obfuscated data surveillance by anthropomorphizing digital spaces and making such products seem immaterial and innocuous.

description: We reconsider top condensate models from the perspective that not only two quark composite fields can form but also four quark ones. We obtain a model which contains a Higgs doublet and a Higgs triplet, where one of the neutral components of the Higgs triplet identifies with the Higgs boson found at the LHC. We discuss some of the phenomenological consequences.

description: We study the partition function of the N=6 supersymmetric U(N_1)_k x U(N_2)_{-k} Chern-Simons-matter (CSM) theory, also known as the ABJ theory. For this purpose, we first compute the partition function of the U(N_1) x U(N_2) lens space matrix model exactly. The result can be expressed as a product of q-deformed Barnes G-function and a generalization of multiple q-hypergeometric function. The ABJ partition function is then obtained from the lens space partition function by analytically continuing N_2 to -N_2. The answer is given by min(N_1,N_2)-dimensional integrals and generalizes the "mirror description" of the partition function of the ABJM theory, i.e. the N=6 supersymmetric U(N)_k x U(N)_{-k} CSM theory. Our expression correctly reproduces perturbative expansions and vanishes for |N_1-N_2|>k in line with the conjectured supersymmetry breaking, and the Seiberg duality is explicitly checked for a class of nontrivial examples.

On the asymptotic density of the support of a Dirichlet convolution

description: Let v be a multiplicative arithmetic function with support of positive asymptotic density. We prove that for any not identically zero arithmetic function f such that \sum_{f(n) \neq 0} 1 / n < \infty, the support of the Dirichlet convolution f * v possesses a positive asymptotic density. When f is a multiplicative function, we give also a quantitative version of this claim. This generalizes a previous result of P. Pollack and the author, concerning the support of Möbius and Dirichlet transforms of arithmetic functions.

description: (Abridged) We report the discovery of CXO J1415.2+3610, a distant (z~1.5) galaxy cluster serendipitously detected in a deep, high-resolution Chandra observation targeted to study the cluster WARP J1415.1+3612 at z=1.03. This is the highest-z cluster discovered with Chandra so far. Moreover, the total exposure time of 280 ks with ACIS-S provides the deepest X-ray observation currently achieved on a cluster at z>1.5. We perform an X-ray spectral fit of the extended emission of the intracluster medium (ICM) with XSPEC, and we detect at a 99.5% confidence level the rest frame 6.7-6.9 keV Iron K_αline complex, from which we obtain z_X=1.46\pm0.025. The analysis of the z-3.6μm color-magnitude diagram shows a well defined sequence of red galaxies within 1' from the cluster X-ray emission peak with a color range [5 < z-3.6 μm < 6]. The photometric redshift obtained by spectral energy distribution (SED) fitting is z_phot=1.47\pm 0.25. After fixing the redshift to z=1.46, we perform the final spectral analysis and measure the average gas temperature with a 20% error, kT=5.8^{+1.2}_{-1.0} keV, and the Fe abundance Z_Fe = 1.3_{-0.5}^{+0.8}Z_\odot. We fit the background subtracted surface brightness with a single beta--model out to 35" and derive the deprojected electron density profile. The ICM mass is 1.09_{-0.2}^{+0.3}\times 10^{13} M_\odot within 300 kpc. The total mass is M_{2500}= 8.6_{-1.7}^{+2.1} \times 10 ^{13} M_\odot for R_{2500}=(220\pm 55) kpc. Extrapolating the profile at larger radii we find M_{500}= 2.1_{-0.5}^{+0.7} \times 10 ^{14} M_\odot for R_{500} = 510_{-50}^{+55}$ kpc. This analysis establishes CXOJ1415.2+3610 as one of the best characterized distant galaxy clusters based on X-ray data alone.

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 mira a presentare i risultati di un’indagine che ha coinvolto docenti, studenti e famiglie nei primi mesi successivi allo stato di emergenza dovuto alla Pandemia da Covid-19, in cui sono state coinvolti docenti, famiglie e studenti. L’obiettivo della ricerca è di esplorare e comprendere come sono cambiati gli aspetti legati alla didattica, alla relazione educativa e al rapporto con le famiglie. I dati emersi, seppur non generalizzabili, evidenziano le difficoltà iniziali incontrate nel rispondere all'emergenza, le quali hanno sottolineato la natura ancora fortemente diseguale della scuola in Italia. Di contro è possibile riscontrare in alcune delle dimensioni indagate (relazione educativa, corresponsabilità scuola-famiglia) efficaci esempi di resilienza.

description: This paper presents a new highly stable periodic approximant to the Al-based F-type icosahedral quasicrystals, i-Al-Pd-TM (TM=transition metals). The structure of this intermetallic Al-Pd-Cr-Fe compound is determined ab initio using single-crystal X-ray diffraction, where the space group is identified to be Pa-3 and the lattice constant 40.5 angstrom. The structure is well described as a dense packing of clusters of two kinds, which are known in the literature as the pseudo-Mackay type and the Bergman type clusters. The clusters are centered at the vertices of a canonical cell tiling, in which the parity of each vertex determines the kind of the associated cluster. Adjacent clusters can be markedly interpenetrated, while the structure requires no glue atoms to fill in the gaps between the clusters. It is shown that the crystal can be designated as a 2x2x2 superstructure of the ordinary cubic 3/2 rational approximant. The superlattice ordering is shown to be of a different kind from the P-type superlattice ordering previously reported in i-Al-Pd-Mn. The present results will greatly improve the understanding of atomic structures of F-type icosahedral quasicrystals and their approximants.
