description: Errors in projecting demographic change have been considerable in recent decades. The fertility declines and increased longevity associated with the concluding global demographic transition have been surprisingly rapid, leading to accelerated ageing of populations in developed countries and in several advanced developing countries. This paper introduces a global demographic model for the analysis of these changes, from which emerge their implications for population sizes, age distributions and gender compositions. From these results are inferred corresponding changes in labour force size and in patterns of consumption and saving which are then analysed using a global economic model in which regional households are disaggregated into eight components comprising four age groups and two genders. Demographic change is found to act most significantly through variations across age groups in savings behaviour and its effects on aggregate savings and investment and their international distribution. Corresponding variation in labour force participation is also significant, acting through labour supply growth and the pattern of comparative advantage. Secondary effects arise from variations in consumption preferences across age groups.

description: We calculate the time delay between different relativistic images formed by black hole gravitational lensing in the strong field limit. For spherically symmetric black holes, it turns out that the time delay between the first two images is proportional to the minimum impact angle. Their ratio gives a very interesting and precise measure of the distance of the black hole. Moreover, using also the separation between the images and their luminosity ratio, it is possible to extract the mass of the black hole. The time delay for the black hole at the center of our Galaxy is just few minutes, but for supermassive black holes with M=10^8 - 10^9 solar masses in the neighbourhood of the Local Group the time delay amounts to few days, thus being measurable with a good accuracy.

description: Supplemental Nutrition Assistance Program (SNAP) helps low income people and households buy food for proper health. This study seeks to examine the effects of changes in economic conditions and welfare on SNAP participation in the Appalachian region. Using county level data, the Spatial Durbin (SDM) Model was used to examine the effect of economic conditions, demographic attributes and institutional factors on SNAP participation. Empirical results from the marginal effects indicate that poverty had the greatest influence on SNAP participation. Findings from this study could be helpful in improving welfare programs in this region.

description: One of the high-level goals of Galactic archaeology is chemical tagging of stars across the Milky Way to piece together its assembly history. For this to work, stars born together must be uniquely chemically homogeneous. Wide binary systems are an important laboratory to test this underlying assumption. Here we present the detailed chemical abundance patterns of 50 stars across 25 wide binary systems comprised of main-sequence stars of similar spectral type identified in Gaia DR2 with the aim of quantifying their level of chemical homogeneity. Using high-resolution spectra obtained with McDonald Observatory, we derive stellar atmospheric parameters and precise detailed chemical abundances for light/odd-Z (Li, C, Na, Al, Sc, V, Cu), $α$ (Mg, Si, Ca), Fe-peak (Ti, Cr, Mn, Fe, Co, Ni, Zn), and neutron capture (Sr, Y, Zr, Ba, La, Nd, Eu) elements. Results indicate that 80% (20 pairs) of the systems are homogeneous in [Fe/H] at levels below 0.02 dex. These systems are also chemically homogeneous in all elemental abundances studied, with offsets and dispersions consistent with measurement uncertainties. We also find that wide binary systems are far more chemically homogeneous than random pairings of field stars of similar spectral type. These results indicate that wide binary systems tend to be chemically homogeneous but in some cases they can differ in their detailed elemental abundances at a level of [X/H] ~ 0.10 dex, overall implying chemical tagging in broad strokes can work.

description: Translating the dietary knowledge among individuals into healthy behavior remains a challenging task. This study examines the causal relationship between dietary knowledge and behavior by including self-efficacy in the models. A series of regression models were developed based on Baron and Kenny (1986) to assess whether self-efficacy mediated the link between the predictor variables and dietary behavior. Regression analyses supported the hypothesized relationships that self-efficacy mediates effects of dietary knowledge and social influences on dietary behavior. Self-efficacy also accounted for variance in eating behavior not explained by knowledge or demographic variables.

description: Restaurants/chefs are increasing their demand for locally produced foods to respond to increasing consumer preferences for these products. Data from a survey of independently owned restaurants in Alabama show that there is tremendous opportunity for local producers to market to restaurants. Fifty-one percent of the restaurants surveyed currently purchase local foods, and over 80 percent of the remaining restaurants would purchase local products if barriers were addressed. To take advantage of this opportunity, producers must be able to consistently supply high quality, fresh products. Farmers must also be aware of and abide by food safety standards to sell to these restaurants.

description: We compute \frac{dσ}{dp_T} of the J/ψproduction in pp collisions at RHIC at \sqrt s = 500 and 200 GeV by using both the color octet and singlet models in the framework of non-relativistic QCD. The J/ψwe compute here includes the direct J/ψfrom the partonic fusion processes and the J/ψcoming from the radiative decays of χ_J's both in the color octet and singlet channel. The high p_T J/ψproduction cross section is computed within the PHENIX detector acceptance ranges: -0.35 < η< 0.35 and 1.2 < \|η| < 2.4, the central electron and forward muon arms. It is found that the color octet contribution to J/ψproduction is dominant at RHIC energy in comparison to the color singlet contributions. We compare our results with the recent preliminary data obtained by PHENIX detector for the high p_T J/ψmeasurements. While the color singlet model fails to explain the data completely the color octet model is in agreement with the single data point above 2 GeV transverse momentum. A measurement of J/ψproduction at RHIC in the next run with better statistics will allow us to determine the validity of the color octet model of J/ψproduction at RHIC energies. This is very important because it is necessary to know the exact mechanism for J/ψproduction in pp collisions at RHIC if one is to make predictions of J/ψsuppression as a signature of quark-gluon plasma. These mechanisms also play an important role in determining the polarized spin structure function of the proton at RHIC.

Without committing to any specific symmetry group, we investigate the 1-loop renormalization group evolutions of the gauge couplings with one and two intermediate breaking scales. We find that depending on the SO(10) breaking chains, gauge coupling unification is compatible with only a handful of choices of representations of the Higgs bosons under the horizontal symmetry.

description: The sale of ready-to-eat salads has increased over the past years, yet little is known about consumer usage and the related safety of these products. This study evaluated the changes of microbiological quality of pre-washed spinach and mixed leafy vegetables during refrigeration storage. Microbial loads were determined by aerobic plate count (APC) and Enterobacteriaceae count (EC). The microbiological quality of pre-washed greens varied widely and deteriorated rapidly in a refrigerator. At “best if used by” date, twenty percent of samples had APC of more than 7.0 Log CFU/g and all samples had EC of more than 5.0 Log CFU/g. It is recommended that consumers purchase and eat pre-washed greens in their entirety as far in advance of the “best if used by” date as possible.

description: The body of theoretical and empirical research that objectively addresses the problem of corruption has grown considerably in recent years (Elliot 1997; Coolidge and Rose-Ackerman 1997; Gill 1998; Girling 1997; HDC 1999; Kaufmann and Sachs 1998; Mauro 1995; Paul and Guhan 1997; Shleifer and Vishnay 1998; Stapenhurst and Kpundeh 1998; Vittal 1999; World Bank 1997). A preliminary analysis of the literature shows that corruption is recognised as a complex phenomenon, as the consequence of more deep seated problems of policy distortion, institutional incentives and governance. It thus cannot be addressed by simple legal acts proscribing corruption. This paper aims at reviewing the different definitions for corruption in addition to its perceived costs and benefits. Furthermore, in an attempt to measure corruption, the paper will address several theories and models that might help in developing a comprehensive model of corruption.

We show that in the quantum case, only N/e distinct ``colors'' are required, where e = 2.71828 . . . If the number of colors is less than optimal, the objects may still be correctly distinguished with some success probability less than 1. We show that the success probability of the quantum scheme is better than the corresponding classical one and is information-theoretically optimal.

description: The nuclear symmetry energy plays a role in determining both the nuclear properties of terrestrial matter as well as the astrophysical properties of neutron stars. The first measurement of the neutron star tidal deformability, from gravitational wave event GW170817, provides a new way of probing the symmetry energy. In this work, we report on new constraints on the symmetry energy from GW170817. We focus in particular on the low-order coefficients: namely, the value of the symmetry energy at the nuclear saturation density, S_0, and the slope of the symmetry energy, L_0. We find that the gravitational wave data are relatively insensitive to S_0, but that they depend strongly on L_0 and point to lower values of L_0 than have previously been reported, with a peak likelihood near L_0 ~ 20 MeV. Finally, we use the inferred posteriors on L_0 to derive new analytic constraints on higher-order nuclear terms.

description: Concentration in several global agricultural input industries has risen significantly; by 2009, the largest four firms in the crop seed, agricultural chemical, animal health, animal genetics/breeding, and farm machinery sectors accounted for more than 50 percent of global market sales in each sector. Factors influencing changes in market structure and concentration vary by industry and include market forces, the emergence of new technologies, and government policies. The largest agricultural input firms are responsible for a large and growing share of global agricultural research and development (R&D), and higher input prices paid by farmers partially reflect the higher quality of inputs created through private-sector R&D.

description: The half-life, 3.8755(12) s, and superallowed branching ratio, 0.5315(12), for ^{22}Mg beta-decay have been measured with high precision. The latter depended on gamma-ray intensities being measured with an HPGe detector calibrated for relative efficiencies to an unprecedented 0.15%. Previous precise measurements of 0^+ to 0^+ transitions have been restricted to the nine that populate stable daughter nuclei. No more such cases exist, and any improvement in a critical CKM unitarity test must depend on precise measurements of more exotic nuclei. With this branching-ratio measurement, we show those to be possible for T_z = -1 parents. We obtain a corrected Ft-value of 3071(9) s, in good agreement with expectations.

description: We show that the leading coupling between a shift symmetric inflaton and the Standard Model fermions leads to an induced electroweak symmetry breaking due to particle production during inflation, and as a result, a unique oscillating feature in non-Gaussianities. In this one parameter model, the enhanced production of Standard Model fermions dynamically generates a new electroweak symmetry breaking minimum, where the Higgs field classically rolls into. The production of fermions stops when the Higgs expectation value and hence the fermion masses become too large, suppressing fermion production. The balance between the above-mentioned effects gives the Standard Model fermions masses that are uniquely determined by their couplings to the inflaton. In particular, the heaviest Standard Model fermion, the top quark, can produce a distinct cosmological collider physics signature characterised by a one-to-one relation between amplitude and frequency of the oscillating signal, which is observable at future 21-cm surveys.

description: Therophilus Wesmael
 Type species: Microdus (Therophilus) conspicuous Wesmael, 1837.
 Comments. The genus was first considered a subgenus of Microdus and erected as a synonym of Bassus by Viereck (1914). In 2009, Sharkey et al. divided Bassus into four genera, i.e., Bassus s.s., Camptothlipis Lytopylus, and Therophilus. Sharkey & Stoelb (2012) placed the type species of Microdus in Therophilus s.s.
 Diagnosis: Due to its polyphyletic origin the genus does not present a fixed combination of diagnostic characteristics, but most members present the following characters: tarsal claw simple with basal lobe; interantennal space with two longitudinal ridges or one median keel; fore wing vein R weak at midlength and bent towards apex of wing; fore wing cubital cell strong and tubular, at least basally; fore wing subbasal cell angled apically; postscutellar sulcus present and sclerite between coxae cavities and metasomal foramen incomplete or narrow.
 Distribution: Worldwide, cosmopolitan. More diverse in subtropical and tropical areas.

description: Looking at the outbreak of SARS-CoV-2 and the global state of emergency imposed due to its pandemic spread, the necessity for antiviral drugs to be immediately available is a priority for the scientific community. Considering that research and implementation of new antiviral therapies or vaccines usually take a long time, the World Health Organization (WHO) has proposed to use in commerce drugs: in fact, repurposing drugs which are already accessible in large quantities is easier to fight against the virus, at least during the first emergency phase. In this article, we discuss various mathematical models which simulate the action of antiviral drug therapies, such as neuraminidase inhibitors (NIs), for the treatment of H1N1 Influenza A virus, by using data collected through in vitro and in vivo experiments. This constitutes a paradigmatic case of study for paving the way to a systematic investigation of the effects of chloroquine and hydroxychloroquine as therapeutics in the treatment of SARS-CoV-2.

description: With the aim of characterizing the dynamical processes involved in the formation of young protostars, we present high angular resolution ALMA dust polarization observations of the Class 0 protostellar cores Serpens SMM1, Emb 8(N), and Emb 8. With spatial resolutions ranging from 150 to 40 au at 870 μm, we find unexpectedly high values of the polarization fraction along the outflow cavity walls in Serpens Emb8(N). We use 3 mm and 1 mm molecular tracers to investigate outflow and dense gas properties and their correlation with the polarization. These observations allow us to investigate the physical processes involved in the Radiative Alignment Torques (RATs) acting on dust grains along the outflow cavity walls, which experience irradiation from accretion processes and outflow shocks. The inner core of SMM1-a presents a polarization pattern with a poloidal magnetic field at the bases of the two lobes of the bipolar outflow. To the south of SMM1-a we see two polarized filaments, one of which seems to trace the redshifted outflow cavity wall. The other may be an accretion streamer of material infalling onto the central protostar. We propose that the polarized emission we see at millimeter wavelengths along the irradiated cavity walls can be reconciled with the expectations of RAT theory if the aligned grains present at '

The dynamical nature of each singularity is elucidated, and we show that both are, in general, dynamically unavoidable, reinforcing the unstable character of previous isotropic and homogeneous cosmological results obtained for the conformal coupling case.

description: Although the SARS-CoV-2 vaccines are highly efficacious at preventing severe disease in the general population, current data are lacking regarding vaccine efficacy (VE) for individuals with mild immunocompromising conditions.A post-hoc, cross-protocol analysis of participant-level data from the blinded phase of four randomized, placebo-controlled, COVID-19 vaccine phase 3 trials (Moderna, AstraZeneca, Janssen, and Novavax) was performed. We defined a “tempered immune system” (TIS) variable via a consensus panel based on medical history and medications to determine VE against symptomatic and severe COVID-19 cases in TIS participants versus non-TIS (NTIS) individuals starting at 14 days after completion of the primary series through the blinded phase for each of the four trials. An analysis of participants living with well-controlled HIV was conducted using the same methods.3,852/30,351 (12.7%) Moderna participants, 3,088/29,868 (10.3%) Novavax participants, 3,549/32,380 (11.0%) AstraZeneca participants, and 5,047/43,788 (11.5%) Janssen participants were identified as having a TIS. Most TIS conditions (73.9%) were due to metabolism and nutritional disorders. Vaccination (versus placebo) significantly reduced the likelihood of symptomatic and severe COVID-19 for all participants for each trial. VE was not significantly different for TIS participants vs NTIS for either symptomatic or severe COVID-19 for each trial, nor was VE significantly different in the symptomatic endpoint for participants with HIV.For individuals with mildly immunocompromising conditions, there is no evidence of differences in VE against symptomatic or severe COVID-19 compared to those with non-tempered immune systems in the four COVID-19 vaccine randomized controlled efficacy trials.

description: We find that the normal muon polarization in the decay K->mu nu_mu gamma is very sensitive to the values of the kaon vector F_V and axial-vector F_A form factors. It is shown that the ongoing KEK-E246 experiment can definitely determine the signs of the sum of the form factors if their difference is fixed from other considerations. This method can also verify the form factor values and signs obtained from the K^+ -> l^+ nu_l e^+ e^- decays. A new experiment with sensitivity to the normal and transverse muon polarizations of about 10^-4 will provide a unique possibility to determine the F_V and F_A values with a few percent accuracy.

description: Dorothee gen. nov.
(Figs 1–18)
 Type species. Dorothee panguanensis n. sp., by present designation.
 Diagnosis. This new genus is similar to Aprix Townes, 1961 and Chamula in having lower tooth of mandible as long as upper tooth (Fig. 11), frons with a single median horn (Figs 11 & 12), apical margin of clypeus without a median pair of tubercles (Fig. 11) and frontal horn without a groove along its upper edge (Fig. 12). However, it differs from Chamula in not having a distinct epomia (Figs 2 & 9) and from Aprix (from Australia) in lacking a dorsal lobe in the lower valve of ovipositor (Fig. 17). Dorothee also differs from Trachyglutus (from Brazil) in having a horn in the frons (Figs 11 & 12).
 Female. Fore wing 14.4 mm. Hind wing 10.2 mm. Body rather slender.
 Head. Frons with a moderate median conical horn (Figs 11 & 12); clypeus wide, convex, its apical margin truncate forming a narrow flange (Fig. 11); malar space 0.85 × as long as the base of mandible (Figs 9 & 11); lower part of gena forming a distinct flange, ventrally bordered by the hypostomal carina (Fig. 9); lower tooth of the mandible about the same length as upper tooth (Fig. 11); eye laterally 3.1 × as long as temple (Fig. 9).
 Mesosoma. Lower corner of pronotum with a sharp end (Figs 2 & 9); epomia almost completely absent (ventrally vestigial) (Figs 2 & 9); epicnemium smooth; notauli distinct, reaching center of mesoscutum (Figs 4 & 9); propodeum convex, with anterior transverse carina complete and strong, posterior transverse carina only represented by sublateral teeth (Figs 2 & 4); transverse furrow at base of propodeum moderately broad (Fig. 2); fore wing with areolet about 1.7 × as wide as high, receiving 2m-cu distad of center, basad of 3rs-m, which is only pigmented in its basal 0.40 and in its apex (Figs 5 & 6); fore wing with 1cu-a basad of M&RS by about 0.13 × its length (Fig. 6).
 Metasoma. Petiole of 1 st abdominal segment subcylindrical, mostly rounded, the juncture of its sternite and tergite not marked by a distinct suture (Figs 14 & 15); base of petiole with a lateral triangular tooth (Fig. 16); apex of first sternite opposite to spiracle (Fig. 14); hind tibia 0.76 × as long as ovipositor (Fig. 13); tip of lower valve of ovipositor without lobe (Fig. 17).
 Etymology. The genus name is dedicated to the German geographer Dorothee Uchtmann, with my respect and admiration for her undergraduate work on deforestation in the Colombian Amazon and wishing her all the best in her Master’s studies in sustainable development.
 Biology. Unknown.

Does GW190425 require an alternative formation pathway than a fast-merging channel?

description: The LIGO/Virgo Scientific Collaboration (LVC) recently announced the detection of a compact object binary merger, GW190425, with a total mass of $3.4^{+0.3}_{-0.1}$ M$_{\odot}$, and individual component masses in the range of about 1.1 to 2.5 $M_{\odot}$. If the constituent compact objects are neutron stars, then the total mass is five standard deviations higher than the mean of $2.66\pm 0.12$ M$_{\odot}$ for Galactic binary neutron stars (BNSs). LVC suggests such massive BNS systems are born from a fast-merging channel, and therefore, their non-detection in the Galaxy to be due to a selection effect. However, we are unable to reconcile the inferred formation efficiency from the reported merger rate, $\mathcal{R}_{\rm GW190425}=460^{+1050}_{-390}$ yr$^{-1}$ Gpc$^{-3}$, with predictions from our own study for fast-merging BNS systems. Moreover, the comparable merger rates of GW190425, and GW170817 are possibly in tension with our results for two reasons: (i) more massive systems are expected to have a lower formation rate, and (ii) fast merging channels should constitute $\lesssim 10\%$ of the total BNS systems if case BB unstable mass transfer is permitted to take place as a formation pathway. We argue that to account for the high merger rate of GW190425 as a BNS system requires: (i) revisiting our understanding of NS formation in supernova explosions, or (ii): that more massive NSs need to be preferentially born with either very weak or very high magnetic fields so that they would be undetectable in the radio surveys. Perhaps massive NSs detected in NS-white dwarf binaries are our clues to the formation path of GW190425 systems.

Investigation of the phase separation property in La$_{0.2}$Pr$_{0.4}$Ca$_{0.4}$MnO$_3$ manganite

description: We report a comprehensive investigation of La0.2Pr0.4Ca0.4MnO3 to clarify the micrometre scale phase separation phenomenon in the mixed valent manganite (La,Pr,Ca)MnO3. The compound shows multiple magnetic transitions, in which the charge-ordered state is converted into a ferromagnetic state in steps with the application of a magnetic field. The ac susceptibility measurements show that the glassy transition at low temperatures does not depend on the frequency, thus indicating the absence of any spin glass behaviour. Magnetization as well as heat capacity measurements indicate that this low temperature transition is magnetic field dependent. The field dependent resistivity at 2K shows a sharp drop indicating that the sample behaviour changes from a high resistive state to a low resistive state, corroborating the conversion of charge-ordered insulating (COI) phase to a ferromagnetic metallic (FMM) phase. Our results point towards the existence of phase separation, rigidity of the low temperature glassy-like phase as well as the conversion of COI phase to FMM phase by the application of magnetic fields.

Scaling of entanglement at quantum phase transition for two-dimensional array of quantum dots

description: With Hubbard model, the entanglement scaling behavior in a two-dimensional itinerant system is investigated. It has been found that, on the two sides of the critical point denoting an inherent quantum phase transition (QPT), the entanglement follows different scalings with the size just as an order parameter does. This fact reveals the subtle role played by the entanglement in QPT as a fungible physical resource.

description: We demonstrate that a rank-preserving transfer from a richer individual to a poorer individual can exacerbate income inequality (when inequality is measured by the Gini coefficient). This happens when individuals’ preferences depend negatively not only on work time (effort) but also on low relative income. It is rigorously shown that the set of preference profiles that gives rise to this perverse effect of a transfer on inequality is a non-empty open subset of all preference profiles. A robust example illustrates this result.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

The Black Hole -- Bulge Mass Relation including Dwarf Galaxies Hosting Active Galactic Nuclei

description: We present a new relationship between central black hole (BH) mass and host galaxy stellar bulge mass extending to the lowest BH masses known in dwarf galaxies ($M_{\rm BH} \lesssim 10^{5} M_{\odot}$; $M_{\star} \sim 10^{9} M_{\odot}$). We have obtained visible and near-infrared $Hubble \ Space \ Telescope \ (HST)$ imaging of seven dwarf galaxies with optically-selected broad-line active galactic nuclei (AGN) and BH mass estimates from single epoch spectroscopy. We perform 2D photometric modeling with GALFIT to decompose the structure of these galaxies and find that the majority have an inner bulge/pseudobulge component with an exponential disk that dominates the total stellar mass. Using the modeling results and color-dependent mass-to-light ratios, we determine the stellar mass of each photometric component in each galaxy. We determine the $M_{\rm BH} - M_{\rm bulge}$ relation using a total of 12 dwarf galaxies hosting broad-line AGNs, along with a comparison sample of 88 galaxies with dynamical BH masses and 37 reverberation-mapped AGNs. We find a strong correlation between BH mass and bulge mass with ${\rm log}(M_{\rm BH}/M_\odot) = (1.24\pm 0.08)~{\rm log}(M_{\rm bulge}/10^{11} M_\odot) + (8.80\pm 0.09)$. The near-linear slope and normalization are in good agreement with correlations found previously when only considering higher mass systems. This work has quadrupled the number of dwarf galaxies on the BH-bulge mass relation, with implications for BH seeding and predictions for gravitational wave detections of merging BHs at higher redshifts with $LISA$.

description: We examine and compare different area spectra that have been recently considered in Loop Quantum Gravity (LQG). In particular we focus our attention on a Equally Spaced (ES) spectrum operator introduced by Alekseev et. al. that has gained recent attention. We show that such operator is not well defined within the LQG framework, and comment on the issue regarding area spectra and QNM frequencies.
