Year: 2021

description: The aim of this research is the analysis of one of the least studied type of notaries in Castille, the ones created by apostolic authority. In order to reach this purpose, we have based this research in the exam of five diplomas from the first half of the 16th century in which notaries are granted with the papal authority. We shall analyse the way this grant was developed, the skills required to these professionals, the functions and wrights they were given, the notarial signs they used or their writing practices, mainly the knowledge of languages and types of scripts.

Does the U.S. Navy’s reliance on objective standards prevent discrimination in promotions and retentions?

Year: 2023

description: To prevent discrimination, the U.S. Navy enlisted-personnel promotion process relies primarily on objective measures. However, it also uses the subjective opinion of a sailor’s superior. The Navy’s promotion and retention process involves two successive decisions: The Navy decides whether to promote an individual, and conditional on that decision, the sailor decides whether to stay. Using estimates of these correlated decision-making processes, we find that during 1997–2008, Blacks and Hispanics were less likely to be promoted than Whites, especially during wartime. The Navy’s decision-making affects Blacks’ differential promotion rates by twice as much as differences in the groups’ characteristics. However, Nonwhite retention probabilities, even when not promoted, are higher than for Whites, in part because they have fewer opportunities in the civilian market. Females have lower promotion rates than males and slightly lower retention rates during wartime.

description: CUPID-0 is the first pilot experiment of CUPID, a next-generation project searching for neutrino-less double beta decay. In its first scientific run, CUPID-0 operated 26 ZnSe cryogenic calorimeters coupled to light detectors in the underground Laboratori Nazionali del Gran Sasso. In this work, we analyzed a ZnSe exposure of 11.34 kg$\times$yr to search for the neutrino-less double beta decay of $^{70}$Zn and for the neutrino-less positron-emitting electron capture of $^{64}$Zn. We found no evidence for these decays and set 90$\%$ credible interval limits of ${\rm T}_{1/2}^{0νββ}(^{70}{\rm Zn}) > 1.6 \times 10^{21}$ yr and ${\rm T}_{1/2}^{0νEC β+}(^{64}{\rm Zn}) > 1.2 \times 10^{22}$ yr, surpassing by almost two orders of magnitude the previous experimental results

description: Extracellular vesicles, including exosomes, cross the blood brain barrier with their contents intact and can be assayed peripherally. Circulating exosomes have been studied in other neurodegenerative disorders, but there is scarce data in schizophrenia. This study aimed to examine neuropathology-relevant protein biomarkers in circulating plasma-derived exosomes from patients with schizophrenia and age- and sex-matched healthy controls. Nanoparticle tracking analysis was used to determine the size and concentration of exosomes. Exosomal membrane marker (CD9) and specific target cargo protein (glial fibrillary acid protein[GFAP], synaptophysin, and α-II-Spectrin) immunopositivity was examined using Western blot analyses with band intensity quantified. Methods were consistent with the ‘Minimal information for studies of extracellular vesicles 2018’ (MISEV2018) guidelines. Exosomal GFAP concentration was significantly higher and α-II-Spectrin expression significantly lower in plasma obtained from schizophrenia patients. No group differences were observed between in plasma exosomal concentration and size or in CD9, calnexin, or synaptophysin levels. Our results demonstrate a differential pattern of exosomal protein expression in schizophrenia compared to matched healthy controls, consistent with the hypothesised astroglial pathology in this disorder. These results warrant further examination of circulating exosomes as vehicles of novel peripheral biomarkers of disease in schizophrenia and other neuropsychiatric disorders.

description: We report the detection of CH3OH emission in comet 46P/Wirtanen on UT 2018 December 8 and 9 using the Atacama Compact Array (ACA), part of the Atacama Large Millimeter/Submillimeter Array (ALMA). These interferometric measurements of CH3OH along with continuum emission from dust probed the inner coma (<2000 km from the nucleus) of 46P/Wirtanen approximately one week before its closest approach to Earth (Δ = 0.089–0.092 au), revealing rapidly varying and anisotropic CH3OH outgassing during five separate ACA executions between UT 23:57 December 7 and UT 04:55 December 9, with a clear progression in the spectral line profiles over a timescale of minutes. We present spectrally integrated flux maps, production rates, rotational temperatures, and spectral line profiles of CH3OH during each ACA execution. The variations in CH3OH outgassing are consistent with Wirtanen’s 9 hr nucleus rotational period derived from optical and millimeter wavelength measurements and thus are likely coupled to the changing illumination of active sites on the nucleus. The consistent blue offset of the line center indicates enhanced CH3OH sublimation from the sunward hemisphere of the comet, perhaps from icy grains. These results demonstrate the exceptional capabilities of the ACA for time-resolved measurements of comets such as 46P/Wirtanen.

description: The paper analyzes a charter issued by the Bosnian voevoda Sandalj Hranić Kosača sealing the agreement established with Venice in consequence of the entry of Kotor in the Venetian Commonwealth (1423). The analysis focuses on document's formal aspects in order to identify the underlying documentary model. For this purpose, all the linked records produced by Venice on this occasion are taken into account. Moreover, an attempt to relate the documentation of Kotor affair to the Venetian practice in making documents about treaties is provided. Such an analysis leads to the conclusion that the Venetian documentary patterns developped for sealing international agreements were adopted in Slavic version of the documentation too.

description: Uranium uptake, translocation and its effects on leaf anatomy in vetiver grass (Vetiveria zizanioides L. Nash) grown in hydroponics were investigated at a wide range of concentrations. At concentrations below 200 ppm (1, 5, 25, 100, and 200 ppm) almost 90–95% of uranium was depleted from the medium within 3 days of treatment, while at other concentrations viz., at 318, 500, 619, 1,000, 5,000, 7,500, and 11,900 ppm, it reached a maximum between 7 and 14 days, with a marginal increase in the depletion thereafter. Most of the uranium could be recovered from plants at concentrations below 200 ppm. On the contrary, a significant reduction in the recovery of uranium was noticed at higher concentrations and the percentage of recovery dropped from 82% at 318 ppm to 35% at 11,900 ppm. While most of the uranium taken up by the plants could be recovered from roots at lower concentrations, a preferential translocation of the element to shoot occurred at concentrations beyond 1,000 ppm. Histological studies of leaves from plants treated with 1,000 ppm uranium displayed the formation of multilayered cells between the epidermis and vascular bundles on the adaxial side in the distal regions of the leaves. The plants were also found to tolerate and survive the radiological and chemical constituents of both uranium mill tailings soil as well as various effluents of uranium mine and mill operations. Further, they could also survive in uranium ore containing 600 ppm of triuranium octoxide (U3O8) and could withstand the amendment of ore with citric acid. The ability of vetiver to take up uranium from solutions to high levels and its survival in effluents, mill tailings soil, and ore coupled with its ecological characteristics makes it an ideal plant for phytoextraction of uranium.
Dalla Francia a Dresda. Le Bibbie portatili della Sächsische Landesbibliothek - Staats- und Universitätsbibliothek
Creators: name: Paolini, Adriana

Year: 2021

description: The Sächsische Landesbibliothek - Staats- und Universitätsbibliothek of Dresden preserves a very interesting collection of medieval and modern manuscripts, once in the most part belonging to the Electoral Library of the Saxon Dukes. The study of the ancient catalogues of the Library has revealed the presence of five portable Bibles copied in the 13th century in the North of France and acquired by the Saxon Court on the antiquarian trade during the 18th century, except for one manuscript which was donated to the Duke Johann Georg I in the 1647. In this essay each Bible has been studied and compared with the others preserved in Dresden and also with the models of the most widespread biblical manuscripts in 13th century Europe. Although these Bibles present codicological and palaeographic features similar to the typical style of the so-called Paris Bibles, each manuscript contains significant textual and codicological variants that lead us to realize the considerable diversity of material forms and reference models circulating in the 13th century. For this reason, the essay is completed not only by a detailed description of the manuscripts but also by three further addenda in which the sequence of the books, the codicological data and the iconography are compared.

description: The paper aims to reconsider the chronological and contextual data of the ‘placitum’ taken in Piacenza with the deacon Gariberto as protagonist. This 'notitia iudicati' was published first by Schiaparelli in 1903 and then again, obviously, in the Manaresi collection (on the date 880 December/881 February). It seems to exhibit for the first time the formulary of the 'ostensio cartae'. Armando Petrucci considered this placitum a forgery. This record contains the transcription of a diploma of Charles III (not otherwise preserved) for the deacon Gariberto: an interpolated text which explains and justifies the judicial occasion.

description: Herein, we present results from observations of the 12CO (J=1-0), 13CO (J=1-0), and 12CO (J=2-1) emission lines toward the Carina nebula complex (CNC) obtained with the Mopra and NANTEN2 telescopes. We focused on massive-star-forming regions associated with the CNC including the three star clusters Tr14, Tr15, and Tr16, and the isolated WR-star HD92740. We found that the molecular clouds in the CNC are separated into mainly four clouds at velocities -27, -20, -14, and -8 km/s. Their masses are 0.7x10^4Msun, 5.0x10^4 Msun, 1.6x10^4 Msun, and 0.7x10^4 Msun, respectively. Most are likely associated with the star clusters, because of their high 12CO (J=2-1)/12CO (J=1-0) intensity ratios and their correspondence to the Spitzer 8 micron distributions. In addition, these clouds show the observational signatures of cloud--cloud collisions. In particular, there is a V-shaped structure in the position--velocity diagram and a complementary spatial distribution between the -20 km/s cloud and the -14 km/s cloud. Based on these observational signatures, we propose a scenario wherein the formation of massive stars in the clusters was triggered by a collision between the two clouds. By using the path length of the collision and the assumed velocity separation, we estimate the timescale of the collision to be ~1 Myr. This is comparable to the ages of the clusters estimated in previous studies.

description: This paper compares methods to remedy missing value problems in survey data. The commonly used methods to deal with this issue are to delete observations that have missing values (case-deletion), replace missing values with sample mean (mean imputation), and substitute a fitted value from auxiliary regression (regression imputation). These methods are easy to implement but have potentially serious drawbacks such as bias and inefficiency. In addition, these methods treat imputed values as known so that they ignore the uncertainty due to 'missingness', which can result in underestimating the standard errors. An alternative method is Multiple Imputation (MI). In this paper, Expectation Maximization (EM) and Data Augmentation (DA) are used to create multiple complete datasets, each with different imputed values due to random draws. EM is essentially maximum-likelihood estimation, utilizing the interdependency between missing values and model parameters. DA estimates the distribution of missing values given the observed data and the model parameters through Markov Chain Monte Carlo (MCMC). These multiple datasets are subsequently combined into a single imputation, incorporating the uncertainty due to the missingness. Results from the Monte Carlo experiment using pseudo data show that MI is superior to other methods for the problem posed here.

description: A major upgrade to the NIRSPEC instrument at the Keck II telescope was successfully completed in time for near-infrared spectroscopic observations of comet 46P/Wirtanen during its exceptionally close flyby of Earth in 2018 December. These studies determined the abundances of several volatiles, including C2H2, C2H6, CH3OH, NH3, HCN, H2CO, and H2O. Long-slit spatial distributions of gas rotational temperature and column density are diagnostic for the presence of icy grains in the coma and understanding if different volatiles are associated with common or distinct outgassing sources. These spatial distributions suggest that C2H2, C2H6, and HCN have a common outgassing source, whereas H2O and CH3OH have additional, more extended sources. The synergy of these findings with observations by space missions (Rosetta and EPOXI) motivates continuing studies to address whether or not C2H6, C2H2, and HCN have a common source of release (plausibly associated with CO2) in a larger sample of comets and whether systematic differences exist in the release of these species compared to H2O and CH3OH. Abundances of volatiles are reported relative to H2O, as traditionally done, as well as C2H6. While not unique, the choice of C2H6 demonstrates the value of extending the chemical taxonomy of parent volatiles in comets toward additional compositional “baselines” and, importantly, closer integration between coma abundances and the underlying volatile associations as revealed by spatial distributions. Our findings on composition and sources of outgassing include information relevant to future evaluations of 46P/Wirtanen as a prospective spacecraft target.

description: Microbial community structure reflects the surrounding natural environment and changes to that environment. Although the subsurface at 5–100 m depth is important for human activities and there are potential risks of environmental pollution in this region, there have been only a few reports of subsurface microbial community structures in terrestrial areas. We investigated the diversity and community compositions of Bacteria and Archaea in boring cores collected from various depths at three different sites in the southern Kanto Plain, Japan. The results of 16S rRNA gene amplicon sequencing using MiSeq showed that the microbial community composition varied with the geological unit. Proteobacteria (Alphaproteobacteria and Gammaproteobacteria) were dominant members within sediments accumulated during the Pleistocene in the Musashino Upland. In contrast, Acidobacteria and Chloroflexi characteristically appeared in the Holocene layers of the Arakawa Lowland. These data suggest that the subsurface microbial composition is controlled by the geological features of the sediments.

description: We introduce a low Mach number equation set for the large-scale numerical simulation of carbon-oxygen white dwarfs experiencing a thermonuclear deflagration. Since most of the interesting physics in a Type Ia supernova transpires at Mach numbers from 0.01 to 0.1, such an approach enables both a considerable increase in accuracy and savings in computer time compared with frequently used compressible codes. Our equation set is derived from the fully compressible equations using low Mach number asymptotics, but without any restriction on the size of perturbations in density or temperature. Comparisons with simulations that use the fully compressible equations validate the low Mach number model in regimes where both are applicable. Comparisons to simulations based on the more traditional anelastic approximation also demonstrate the agreement of these models in the regime for which the anelastic approximation is valid. For low Mach number flows with potentially finite amplitude variations in density and temperature, the low Mach number model overcomes the limitations of each of the more traditional models and can serve as the basis for an accurate and efficient simulation tool.

description: Low dimensional systems, nanowires, in particular, have exhibited excellent optical and electronic properties. Understanding the thermal properties in semiconductor nanowires is very important for their applications in their electronic devices. In the present study, the thermal conductivity of a freestanding silicon nanowire (NW) is estimated employing the Raman spectroscopy. The advantage of this technique is that the light source (laser) can be used both as heating and excitation source. The variations of the first-order Raman peak position of the freestanding silicon NW with respect to temperature and laser power are carried out. A critical analysis of effective laser power absorbed by exposed silicon NW, the detailed Raman study along with the concept of longitudinal heat distribution in silicon NW, the thermal conductivity of the freestanding silicon NW of 112 nm diameter is estimated to be ~53 W/m.K.

description: The authors examine the way in which the paleographic analysis can enrich the historical knowledge of the public administration in a local context of the Carolingian age. In particular, the case of Lucca is examined. In fact, Lucca offers a privileged point of observation due to the extraordinary richness of its surviving documentation. The analysis focuses on only one type of contract: the exchange that involves ecclesiastical institutions. Finally, the possibility of a more in-depth material analysis of the early medieval document is presented, aiming not only at handwriting classification but also at understanding the timing according to which documents were written.

description: A major upgrade to the NIRSPEC instrument at the Keck II telescope was successfully completed in time for near-infrared spectroscopic observations of comet 46P/Wirtanen during its exceptionally close flyby of Earth in 2018 December. These studies determined the abundances of several volatiles, including C2H2, C2H6, CH3OH, NH3, HCN, H2CO, and H2O. Long-slit spatial distributions of gas rotational temperature and column density are diagnostic for the presence of icy grains in the coma and understanding if different volatiles are associated with common or distinct outgassing sources. These spatial distributions suggest that C2H2, C2H6, and HCN have a common outgassing source, whereas H2O and CH3OH have additional, more extended sources. The synergy of these findings with observations by space missions (Rosetta and EPOXI) motivates continuing studies to address whether or not C2H6, C2H2, and HCN have a common source of release (plausibly associated with CO2) in a larger sample of comets and whether systematic differences exist in the release of these species compared to H2O and CH3OH. Abundances of volatiles are reported relative to H2O, as traditionally done, as well as C2H6. While not unique, the choice of C2H6 demonstrates the value of extending the chemical taxonomy of parent volatiles in comets toward additional compositional “baselines” and, importantly, closer integration between coma abundances and the underlying volatile associations as revealed by spatial distributions. Our findings on composition and sources of outgassing include information relevant to future evaluations of 46P/Wirtanen as a prospective spacecraft target.

Au croisement des contenus et de la matière : les structures des sept pandectes bibliques grecques du premier millénaire
Creators: name: Andrist, Patrick
Publisher: name: Scrineum Rivista
Year: 2021

description: This article studies the architecture of the seven pandects of the Greek Christian Bible from the first millennium that are still preserved today (the codices Vaticanus, Sinaiticus, Alexandrinus, Ephraemi rescriptus, Basilianus (= Vat. gr. 2106 + Ven. gr. 1), «Pariathonensis» (= Par. gr. 14 + Stavronikita 29) and the Leo Bible) from a codicological comparative perspective, based on the analysis of both their physical and textual structures. The first part explains the methodology; each codex is then studied individually and its architecture summarized in a graphical representation. Some previously overlooked elements about the quires of the Alexandrinus, the Basilianus etc. are brought to light. The Bibles are then compared and their peculiarities are placed in a historical framework. A suggested reconstruction of the quire structures of the Ephraemi Rescriptus and the Pariathonensis is presented in the appendices. This article draws conclusions about the scarcity, modularity and variety of these pandects. It observes that they were all designed for possible binding and circulation in several volumes, and it stresses the different ways in which the disputed books in the canon (Maccabees, Revelation, Hermas, Barnabas etc.) are sometimes included as autonomous and thus removable entities... and sometimes not.

description: We study systems of simple point processes that admit stochastic intensities. We represent these point processes as thinnings of Poisson measures and are interested in a convergence result of such systems. This result states that, if the stochastic intensities of the limit point processes are independent of the underlying Poisson measures, the convergence in distribution in Skorohod topology of the stochastic intensities implies the same convergence for the point processes.

title: The characterisation of mullite-related phases by hydrothermal synthesis
Creators: name: Booth, Mark William
Publisher: name: The Open University
Year: 1995

description: The aluminosilicate called mullite has been prepared by hydrothermal processing from aluminium- and silicon- acetates. The phase evolution of the products and the mechanism of formation of mullite from its precursors has been examined by x-ray powder diffraction, magic-angle spinning NMR spectroscopy, FTIR spectroscopy and electron microscopy. The product obtained from co-processing aluminium- and silicon- acetates was found to be a biphasic material with strong interfacial interactions between pseudoboehmite and amorphous silica-gel type phases. This interfacial interaction resulted in mullite being formed after calcination at 1250°C, which is a lower temperature than would normally be expected for the formation of mullite. Lattice parameter measurements of mullite calcined up to 1400°C suggested that a metastable state may be formed at the lower temperature. The effect of adding acid to the reagent mixture was examined and found to have no effect on the chemistry of the phase evolution of the products.

The synthesis of iron-doped mullite has also been examined by x-ray powder diffraction, Mössbauer spectroscopy, EXAFS and electron microscopy. The iron-containing phases in dried intermediate materials exhibited superparamagnetism. Upon calcination iron-doped mullite formed at 1150°C with an iron content up to 14 mol%. EXAFS showed the iron to occupy octahedral sites in the mullite structure.

The synthesis of magnesium-aluminium spinel has been examined using a similar methodology. The interfacial interaction between the initial precursors was found to be stronger than that observed in the aluminosilicate system. This increase in interfacial interaction is associated with the lower temperature required to form spinel (400°C).

description: This article examines technical efficiency of the Chinese grain sector using the framework of stochastic production frontier. The results reveal that: the marginal products of labor and fertilizer are much smaller than that of land; human capital and farm-level specialization have positive effect on efficiency, land fragmentation is detrimental to efficiency, and elder farmers are as efficient as younger farmers. We also examine the effects of size, mechanization and geographic location. Simulation results show that significant output gains can be obtained by eliminating land fragmentation, improving rural education and promoting specialization and mechanization.
Bose-representation for a strongly coupled nonequilibrim fermionic superfluid in a time-dependent trap

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: Using the functional integral formulation of a nonequilibrium quantum many-body theory we develop a regular description of a Fermi system with a strong attractive interaction in the presence of an external time-dependent potential. In the strong coupling limit this fermionic system is equivalent to a noequilibrium dilute Bose gas of diatomic molecules. We also consider a nonequilibrim strongly coupled Bardeen-Cooper-Schrieffer (BCS) theory and show that it reduces to the full nonlinear time-dependent Gross-Pitaevski (GP) equation, which determines an evolution of the condensate wave function.

description: The 2018 perihelion passage of comet 46P/Wirtanen afforded an opportunity to measure the abundances and spatial distributions of coma volatiles in a Jupiter-family comet with exceptional spatial resolution for several weeks surrounding its closest approach to Earth (Δmin ∼0.078 au on UT December 16). We conducted near-infrared spectroscopic observations of 46P/Wirtanen using iSHELL at the NASA Infrared Telescope Facility on UT 2018 December 18 in direct coordination with observations using the newly upgraded NIRSPEC-2 instrument at the W. M. Keck Observatory, and securely detected fluorescent emission from CH3OH, C2H6, and H2O. This coordinated campaign utilizing the two premier near-infrared facilities in the northern hemisphere enabled us to sample distinct projections of the coma into the plane of the sky simultaneously, and provided an unprecedented view into the inner coma of 46P/Wirtanen near closest approach. We report rotational temperatures, production rates, and abundance ratios (i.e., mixing ratios) for all sampled species and compare our iSHELL results to simultaneous (or near-simultaneous) measurements taken with NIRSPEC-2. We demonstrate the extraordinary synergy of coordinated measurements using iSHELL and NIRSPEC-2, and advocate for future cometary studies that jointly leverage the capabilities of these two facilities.

description: We consider a high-dimensional mixture of two Gaussians in the noisy regime where even an oracle knowing the centers of the clusters misclassifies a small but finite fraction of the points. We provide a rigorous analysis of the generalization error of regularized convex classifiers, including ridge, hinge and logistic regression, in the high-dimensional limit where the number $n$ of samples and their dimension $d$ go to infinity while their ratio is fixed to $α= n/d$. We discuss surprising effects of the regularization that in some cases allows to reach the Bayes-optimal performances. We also illustrate the interpolation peak at low regularization, and analyze the role of the respective sizes of the two clusters.

description: Extracellular vesicles, including exosomes, cross the blood brain barrier with their contents intact and can be assayed peripherally. Circulating exosomes have been studied in other neurodegenerative disorders, but there is scarce data in schizophrenia. This study aimed to examine neuropathology-relevant protein biomarkers in circulating plasma-derived exosomes from patients with schizophrenia and age- and sex-matched healthy controls. Nanoparticle tracking analysis was used to determine the size and concentration of subject exosomes. Exosomal membrane marker (CD9) and specific target cargo protein (glial fibrillary acid protein[GFAP], synaptophysin, and α-II-Spectrin) immunopositivity was examined using Western blot analyses with band intensity quantified. Methods were consistent with the “Minimal information for studies of extracellular vesicles 2018” (MISEV2018) guidelines. Exosomal GFAP concentration was significantly higher and α-II-Spectrin expression significantly lower in plasma obtained from schizophrenia patients. No group differences were observed between in plasma exosomal concentration and size or in CD9, calnexin, or synaptophysin levels. Our results demonstrate a differential pattern of exosomal protein expression in schizophrenia compared to matched healthy controls, consistent with the hypothesized astroglial pathology in this disorder. These results warrant further examination of circulating exosomes as vehicles of novel peripheral biomarkers of disease in schizophrenia and other neuropsychiatric disorders.
