description: PRENOLEPIS AMBLYOPS, n. sp.
[[worker]]. Longueur 2,4 à 2,6 mill. Mandibules armées de six dents, fortement striées, avec des points épars. Stature et forme trapue de la P. Ellisii, dont elle se distingue cependant par l'échancrure mésométanotale beaucoup plus faible, peu apparente. Tête encore plus large que chez la P. Ellisii, sans les mandibules, presque aussi large que longue et aussi large devant que derrière. Les scapes dépassent le bord postérieur de la tête d'un bon tiers de leur longueur. Les yeux sont plats et de moitié plus petits que chez la P. Ellisii et les espèces voisines; ils sont plus étroits que la base des mandibules (bien plus large chez les autres espèces) et ont un nombre bien moins grand de facettes.
Le thorax est court et trapu, le pronotum plus large que long, comme chez la P. Ellisii. La face basale du métanotum est plus courte que la face déclive.
Luisante, très faiblement et éparsément ponctuée, çà et là (mésono- tum) chagrinée-ponctuée; métanotum très luisant et presque lisse.
Des poils dressés d'un noir brun, très grossiers, mais assez pointus, sont répandus sur tout le corps, sur les pattes et sur les scapes; sur ces derniers, ils sont plus fins et plus courts. En outre, une pubescence adjacente jaunâtre très fine, un peu pruineuse, se trouve assez abondamment sur les pattes, les scapes et l'abdomen, tandis qu'elle est très éparse ailleurs.
D'un jaune testacé pâle, analogue à celui du Lasius flavus. Mandibules et abdomen d'un jaune un peu plus brunâtre; tête d'un jaune un peu plus rougeâtre.
Environs de la ville d'Anosibé (province des Bezanozanô), à trois journees à l'est-sud-est d'Antananarivô (M. Sikora).
Cette curieuse espèce se distingue du premier coup de toutes les autres par sa couleur jaune pâle avec ses soies noires, qui ressortent d'autant plus distinctement, ainsi que par ses petits yeux et sa taille encore plus trapue que celle de la P. Ellisii. Elle doit avoir des m œ urs plus ou moins hypogees, ce qui n'est le cas d'aucune des espèces du genre connues jusqu'ici.

description: We present the highest resolution images to date of caustics formed by wave dark matter ($ψ$DM) fluctuations near the critical curves of cluster gravitational lenses. We describe the basic magnification features of $ψ$DM in the source plane at high macromodel magnification and discuss specific differences between the $ψ$DM and standard cold dark matter (CDM) models. The unique generation of demagnified counterimages formed outside the Einstein radius for $ψ$DM is highlighted. Substructure in CDM cannot generate such demagnified images of positive parity, thus providing a definitive way to distinguish $ψ$DM from CDM. Highly magnified background sources with sizes $r\approx 1pc$, or approximately a factor of ten smaller than the expected de Broglie wavelength of $ψ$DM, offer the best possibility of discriminating between $ψ$DM and CDM. These include objects such as very compact stellar clusters at high redshift that JWST is finding in abundance.

description: We report the discovery of Serenity-18, a galaxy at z=5.939 for which we could measure the content of molecular gas, M(H_2)~ 5 x10^9 M_sun, traced by the CO(6-5) emission, together with the metal-poor ([Fe/H]=-3.08 +- 0.12, [Si/H]=-2.86 +- 0.14) gas clump/filament which is possibly feeding its growth. The galaxy has an estimated star formation rate of ~100 M_sun yr^{-1}, implying that it is a typical main sequence galaxy at these redshifts. The metal-poor gas is detected through a damped Lyman-alpha absorber (DLA) observed at a spatial separation of 40 kpc and at the same redshift of Serenity-18, along the line of sight to the quasar SDSS J2310+1855 (z_em = 6.0025). The chemical abundances measured for the damped Lyman-alpha system are in very good agreement with those measured for other DLAs discovered at similar redshifts, indicating an enrichment due to massive PopII stars. The galaxy/Damped system we discovered is a direct observational evidence of the assembly of a galaxy at the edge of the reionization epoch.

Finite-Temperature Corrections in the Dilated Chiral Quark Model

description: We calculate the finite-temperature corrections in the dilated chiral quark model using the effective potential formalism. Assuming that the dilaton limit is applicable at some short length scale, we interpret the results to represent the behavior of hadrons in dense {\it and} hot matter. We obtain the scaling law, $\frac{f_π(T)}{f_π} = \frac{m_Q (T)}{m_Q} \simeq \frac{m_σ(T)}{m_σ}$ while we argue, using PCAC, that pion mass does not scale within the temperature range involved in our Lagrangian. It is found that the hadron masses and the pion decay constant drop faster with temperature in the dilated chiral quark model than in the conventional linear sigma model that does not take into account the QCD scale anomaly. We attribute the difference in scaling in heat bath to the effect of baryonic medium on thermal properties of the hadrons. Our finding would imply that the AGS experiments (dense {\it and} hot matter) and the RHIC experiments (hot and dilute matter) will ``see" different hadron properties in the hadronization phase.

The impact of Faraday effects on polarized black hole images of Sagittarius A*

description: We study model images and polarization maps of Sagittarius A* at 230 GHz. We post-process GRMHD simulations and perform a fully relativistic radiative transfer calculation of the emitted synchrotron radiation to obtain polarized images for a range of mass accretion rates and electron temperatures. At low accretion rates, the polarization map traces the underlying toroidal magnetic field geometry. At high accretion rates, we find that Faraday rotation internal to the emission region can depolarize and scramble the map. We measure the net linear polarization fraction and find that high accretion rate "jet-disc" models are heavily depolarized and are therefore disfavoured. We show how Event Horizon Telescope measurements of the polarized "correlation length" over the image provide a model-independent upper limit on the strength of these Faraday effects, and constrain plasma properties like the electron temperature and magnetic field strength.

description: Self-help is considered a culture, a social movement, a lifestyle based on reciprocity, and a methodology to overcome situations of hardship. It is based on the participatory action of people within a group who, starting from a problem, decide to activate themselves to provide help contributing with their own history and their own knowledge, and skills. The focus of Self-Mutual-Aid (SMA) is the group; this experience makes subjects feel united. Emotional participation in group life triggers a circular communication, which lead members to recognize and experience skills, even identifying unexpressed personal characteristics. The diffusion of communication technologies has enabled the development of brand new forms of self-help. The potential offered by Web 2.0 contributed to redefine the configuration of SMA. The phenomenon of online SMA groups is growing, taking on different forms, such as: SMH online groups, SMA communities, episodic experiences. Online SMA groups represent an important source of support, and this due to the potential that the network has in helping relationships. The analysis is focused on a particular virtual platform, called GenGle, which is, to date, the first social network dedicated to single parents and their children. GenGle was born in 2014 as a social aggregator; it was created to provide real support to single-parent families. The fundamental aim of this research is to evaluate the potential of GenGle movement, as a group of Self-Mutual-Aid, and if and how it could be considered an effective model of educational care.

description: With the increasing complexity of modern industrial automatic and robotic systems, an increasing burden is put on the operators, who are requested to supervise and interact with such complex systems, typically under challenging and stressful conditions. To overcome this issue, it is necessary to adopt a responsible approach based on the anthropocentric design methodology, such that machines adapt to the humans capabilities. Moving along these lines, a methodological approach called MATE was introduced in [1], which consists in devising complex automatic or robotic solutions that measure current operator's status, adapting the interaction accordingly, and providing her/him with proper training to improve the interaction and learn lacking skills and expertise. In this paper we propose an evaluation and validation procedure to guarantee the achievement of the requirements of a MATE system.

description: The paper deals with the issue of the parents’ affective-educational function towards their offspring, after the failure of their union and comments on the Pillon bill. This bill strictly defines the time spent by minor children with each of the parents. This option appears very critical: the task of the legislator should only be to define a principle; the time for children to attend with each parent should be ample, bearing in mind the concrete situation and children’s need for a serene and balanced growth. The Pillon bill also offers the opportunity for an educational reflection on the topic of the “right of love”, as a subjective right to parental affection, essential for the emotional life of children and for their harmonious education. Denying the right of love means denying freedom and dignity.

description: A period of early matter domination can give rise to the correct dark matter abundance for a broad range of dark matter annihilation rate $\langle σ_{\rm ann} v \rangle_{\rm f}$. Here, we examine this scenario for situations where $\langle σ_{\rm ann} v \rangle_{\rm f}$ is below the nominal value for thermal dark matter $3 \times 10^{-26}$ cm$^3$ s$^{-1}$ as possibly indicated by some recent experiments. We show that obtaining the correct relic abundance sets a lower bound on the duration of early matter domination era in this case. On the other hand, provided that the post-inflationary universe has an equation of state characterized by $w \leq 1/3$, the requirement that the scalar spectral index $n_s$ be within the observationally allowed range limits the duration of this epoch from above. By combining these considerations, we show that the current and future cosmic microwave background experiments can tightly constrain the parameter space for this scenario. In particular, models of inflation with a tensor-to-scalar ratio below ${\cal O}(0.01)$ may disfavor non-thermal supersymmetric dark matter from a modulus-driven early matter domination epoch.

description: Context. Recent astrometric and spectroscopic surveys of OB stars have revealed a few stellar-mass black holes (BHs) with orbital periods as low as 10 days. No X-ray counterpart has been detected, due to the absence of a radiatively efficient accretion disk around the BH. Yet, dissipative processes in the hot, dilute and strongly magnetized plasma around the BH (so-called BH corona) can still lead to non-thermal X-ray emission (e.g. synchrotron).
 Aims. We determine the X-ray luminosity distribution from BH+OB star binaries up to orbital periods of a few thousand days.
 Methods. We use detailed binary evolution models computed with MESA for initial primary masses of 10-90 $M_{\odot}$ and orbital periods from 1-3000 d. The X-ray luminosity is computed for a broad range of radiative efficiencies.
 Results. We show that particle acceleration through magnetic reconnection can heat the BH corona. A substantial fraction of the gravitational potential energy from the accreted plasma is converted into non-thermal X-ray emission. Our population synthesis analysis predicts at least 28 (up to 72) BH+OB star binaries in the Large Magellanic Cloud (LMC) to produce X-ray luminosity above 10$^{31}$ erg$\,$s$^{-1}$, observable through focused Chandra observations. We identify a population of SB1 systems in the LMC and HD96670 in the Milky Way comprising O stars with unseen companions of masses above 2.3 $M_{\odot}$ that aligns well with our predictions. The predicted luminosities of the OB companions to these X-ray-emitting BHs are 10$^{4.5-5.5}$ $L_{\odot}$.
 Conclusions. These results make the case for long-time exposure in X-rays of the stellar-mass BH candidates identified around OB stars. It will constrain the underlying population of X-ray-faint BHs, the evolution from single to double degenerate binaries, and the progenitors of gravitational wave mergers. (Abridged)

description: Spin-dependent parton distributions in the polarized virtual photon are investigated in QCD up to the next-to-leading order (NLO). In the case $Λ^2 \ll P^2 \ll Q^2$, where $-Q^2$ ($-P^2$) is the mass squared of the probe (target) photon, parton distributions can be predicted completely up to the NLO, but they are factorization-scheme-dependent. Parton distributions are analyzed in four different factorization schemes and their scheme dependence are discussed. Particular attentions are paid to the axial anomaly effect on the first moments of quark parton distributions, and also to the large-$x$ behaviors of the parton distributions. Gluon distribution in the virtual photon is found to be factorization-scheme independent up to the NLO.

Anti-Diffusion in Continuous Opinion Dynamics

description: Considerable effort using techniques developed in statistical physics has been aimed at numerical simulations of agent-based opinion models and analysis of their results. Such work has elucidated how various rules for interacting agents can give rise to steady state behaviors in the agent populations that vary between consensus and fragmentation. At the macroscopic population level, analysis has been limited due to the lack of an analytically tractable governing macro-equation for the continuous population state. We use the integro-differential equation that governs opinion dynamics for the continuous probability distribution function of agent opinions to develop a novel nonlinear partial differential equation for the evolution of opinion distributions. The highly nonlinear equation allows for the generation of a system of approximations. We consider three initial population distributions and determine their small-time behavior. Our analysis reveals how the generation of clusters results from the interplay of diffusion and anti-diffusion and how initial instabilities arise in different regions of the population distribution.

description: This paper proposes a new stochastic model of traffic dynamics in Lagrangian coordinates. The source of uncertainty is heterogeneity in driving behavior, captured using driver-specific speed-spacing relations, i.e., parametric uncertainty. It also results in smooth vehicle trajectories in a stochastic context, which is in agreement with real-world traffic dynamics and, thereby, overcoming issues with aggressive oscillation typically observed in sample paths of stochastic traffic flow models. We utilize ensemble filtering techniques for data assimilation (traffic state estimation), but derive the mean and covariance dynamics as the ensemble sizes go to infinity, thereby bypassing the need to sample from the parameter distributions while estimating the traffic states. As a result, the estimation algorithm is just a standard Kalman-Bucy algorithm, which renders the proposed approach amenable to real-time applications using recursive data. Data assimilation examples are performed and our results indicate good agreement with out-of-sample data.

description: Over the last two decades, a new model of private welfare addressed to elders in which migrant women are usually engaged as domestic caregivers has been spreading in many European Countries, especially in Italy. About one million of women has migrated towards Italy alone as a way to provide to their families, especially children, who usually are left behind. The experience of these workers as ‘long distance mothers’ appears important to be studied from a pedagogical perspective, considering the intersecting vulnerabilities of being women, migrant and also workers in a poorly protected and underestimated working sector. This article aims to present the results of a multiple case study carried out on three different Italian projects aiming to support long distance parenting for post-socialist families. The paper finally suggests some empirically based guidelines aiming to promote the support for transnational families.

description: We propose a method for the calculation of vacuum expectation values (VEVs) given a non-trivial, long-distance vacuum wave functional (VWF) of the kind that arises, for example, in variational calculations. The VEV is written in terms of a Schrödinger-picture path integral, then a local expansion for (the logarithm of the) VWF is used. The integral is regulated with an explicit momentum cut-off, $Λ$. The resulting series is not expected to converge for $Λ$ larger than the mass-gap but studying the domain of analyticity of the VEVs allows us to use analytic continuation to estimate the large-$Λ$ limit. Scalar theory in 1+1 dimensions is analyzed, where (as in the case of Yang-Mills) we do not expect boundary divergences.

description: We present the photometric sample of a faint galaxy survey carried out in the southern hemisphere, using CCDs on the 3.60m and NTT-3.5m telescopes at La Silla (ESO). The survey area is a continuous strip of 0.2 deg x 1.53 deg located at high galactic latitude (-83 deg) in the Sculptor constellation. The photometric survey provides total magnitudes in the bands B, V (Johnson) and R (Cousins) to limiting magnitudes of 24.5, 24.0, 23.5 respectively. To these limits, the catalog contains about 9500, 12150, 13000 galaxies in B, V, R bands respectively and is the first large digital multi-colour photometric catalog at this depth. This photometric survey also provides the entry catalog for a fully-sampled redshift survey of ~ 700 galaxies with R < 20.5 (Bellanger et al. 1995). In this paper, we describe the photometric observations and the steps used in the data reduction. The analysis of objects and the star-galaxy separation with a neural network are performed using SExtractor, a new photometric software developed by E. Bertin (1996). The photometric accuracy of the resulting catalog is ~ 0.05 mag for R < 22. The differential galaxy number counts in B, V, R are in good agreement with previously published CCD studies and confirm the evidence for significant evolution at faint magnitudes as compared to a standard non evolving model (by factors 3.6, 2.6, 2.1). The galaxy colour distributions B-R, B-V of our sample show a blueing trend of ~ 0.5 mag between 21 < R < 23.5 in contrast to the V-R colour distribution where no significant evolution is observed.

description: Context: Interferometric imaging is algorithmically and computationally challenging as there is no unique inversion from the measurement data back to the sky maps, and the datasets can be very large. Many imaging methods already exist, but most of them focus either on the accuracy or the computational aspect. Aims: This paper aims to reduce the computational complexity of the Bayesian imaging algorithm resolve, enabling the application of Bayesian imaging for larger datasets. Methods: By combining computational shortcuts of the CLEAN algorithm with the Bayesian imaging algorithm resolve we developed an accurate and fast imaging algorithm which we name fast-resolve. Results: We validate the accuracy of the presented fast-resolve algorithm by comparing it with results from resolve on VLA Cygnus A data. Furthermore, we demonstrate the computational advantages of fast-resolve on a large MeerKAT ESO 137-006 dataset which is computationally out of reach for resolve. Conclusions: The presented algorithm is significantly faster than previous Bayesian imaging algorithms, broadening the applicability of Bayesian interferometric imaging. Specifically for the single channel VLA Cygnus A datasets fast-resolve is about $144$ times faster than resolve. For the MeerKAT dataset with multiple channels the computational speedup of fast-resolve is even larger.

The dearth of halo dwarf galaxies: is there power on short scales?

description: N-body simulations of structure formation with scale-invariant primordial perturbations show significantly more virialized objects of dwarf-galaxy mass in a typical galactic halo than are observed around the Milky Way. We show that the dearth of observed dwarf galaxies could be explained by a dramatic downturn in the power spectrum at small distance scales. This suppression of small-scale power might also help mitigate the disagreement between cuspy simulated halos and smooth observed halos, while remaining consistent with Lyman-alpha-forest constraints on small-scale power. Such a spectrum could arise in inflationary models with broken scale invariance.

description: We report an interesting case where magnetic phenomena can transcend mesoscopic scales. Our system consists of tubes created by assembly of dipolar spheres. The cylindrical topology results in the breakup of degeneracy observed in the planar square and triangular packings. As far as the ground state is concerned, tubes switch from circular to axial magnetization with increasing tube length. All magnetostatic properties found in magnetic nanotubes, in which the dipolar interaction is comparable or dominate over the exchange interaction, are reproduced by the dipolar tubes including an intermediary helically magnetized state. Besides, we discuss antiferromagnetic phases and an interesting intermediary vortex state resulting from the square arrangement of the dipolar spheres.
Paternità emigrata, transnazionale, ritrovata: in conversazione con la comunità bangladese di Firenze

description: What relationships are being established between fatherhood and human mobility? How the paths of these two social realities intersect, and what mutual influences may derive from? And what if these dynamics happen to be incorporated into a transnational dimension between Bangladesh and Italy? Starting from these possible questions, this paper aims at analysing the topic of emigrated, transnational, and eventually regained fatherhood, against family reunifications within the Bangladeshi community of Florence. From this perspective, the reflection lays particular emphasis on the experience of separation and reunification in the context of transnational migrations, on the resultant father-child relationship, and the impact that the phenomenon of transnational parenthood may produce upon educational relationships and practices in family.

description: Severe acute pancreatitis (SAP) usually causes multiple-organ dysfunction syndrome and exhibits a high mortality rate. It has been previously reported that berberine, as a dominant alkaloid, can be effectively used against inflammation. However, there is limited data on the effects of berberine hydrochloride (BBRH) on inflammation in SAP rat models. Male Sprague–Dawley rats were given preliminary intraperitoneal injections of BBRH 30 min prior to retrograde infusion of 5% sodium taurocholate in their biliopancreatic ducts. The rats were sacrificed 12 h after taurocholate administration, and tissues and blood samples were then acquired for histological, chemical, and molecular analyses. The SAP models exhibited enhanced edema, ascitic fluid volume, neutrophil infiltration, serum amylase and lipase levels, and interleukin (IL)-6, tumor necrosis factor-α, and IL-1β levels, and reduced IL-10 concentration, while BBRH administration reversed these changes. Further study showed that in the SAP model, protein and mRNA levels of nuclear factor kappa-light-chain-enhancer of activated B (NFκB) p65 and toll-like receptor 4 (TLR4) were increased and inhibitor of nuclear factor kappa B (IκBα) expression was decreased, while pretreatment with BBRH significantly decreased the activation of the TLR4/IκBα/NFκB pathway. The data obtained displayed that BBRH mitigated acute pancreatitis by suppressing the TLR4/IκB/NFκB pathway.
Coherent scattering of high-energy photon in a medium

description: The coherent scattering of photon in the Coulomb field (the Delbrück scattering) is considered for the momentum transfer $Δ\ll m$ in the frame of the quasiclassical operator method. In high-energy region this process occurs over rather long distance. The process amplitude is calculated taking into account the multiple scattering of particles of the intermediate electron-positron pair in a medium. The result is the suppression of the process. Limiting cases of weak and strong effects of the multiple scattering are analyzed. The approach used is the generalization of the method developed by authors for consideration of the Landau-Pomeranchuk-Migdal effect.

description: In this study, we use our recently prepared graphene oxide (GO) with an almost intact σ-framework of C-atoms (ai-GO) to probe the thermal stability of the carbon framework for the first time. Ai-GO exhibits few defects only by preventing CO2 formation during synthesis. Ai-GO was thermally treated before chemical reduction and subsequently the resulting defect density in graphene was determined by statistical Raman microscopy. Surprisingly, the carbon framework of ai-GO is stable in thin films up to 100 °C. Furthermore, we find evidence for an increasing quality of ai-GO upon annealing at 50 °C before reduction. The carbon framework of GO prepared according to the popular Hummers method (GO-c)appears to be less stable and decomposition starts at 50 °C what is qualitatively indicated by CO2-trapping experiments in μm-thin films. Information about the stability of GO is important for storing, processing and applying GO in applications.

description: Recognizing Traffic Signs using intelligent systems can drastically reduce the number of accidents happening world-wide. With the arrival of Self-driving cars it has become a staple challenge to solve the automatic recognition of Traffic and Hand-held signs in the major streets. Various machine learning techniques like Random Forest, SVM as well as deep learning models has been proposed for classifying traffic signs. Though they reach state-of-the-art performance on a particular data-set, but fall short of tackling multiple Traffic Sign Recognition benchmarks. In this paper, we propose a novel and one-for-all architecture that aces multiple benchmarks with better overall score than the state-of-the-art architectures. Our model is made of residual convolutional blocks with hierarchical dilated skip connections joined in steps. With this we score 99.33% Accuracy in German sign recognition benchmark and 99.17% Accuracy in Belgian traffic sign classification benchmark. Moreover, we propose a newly devised dilated residual learning representation technique which is very low in both memory and computational complexity.
On the physical mechanisms governing the cloud lifecycle in the Central Molecular Zone of the Milky Way

description: We apply an analytic theory for environmentally-dependent molecular cloud lifetimes to the Central Molecular Zone of the Milky Way. Within this theory, the cloud lifetime in the Galactic centre is obtained by combining the time-scales for gravitational instability, galactic shear, epicyclic perturbations and cloud-cloud collisions. We find that at galactocentric radii $\sim 45$-$120$ pc, corresponding to the location of the '100-pc stream', cloud evolution is primarily dominated by gravitational collapse, with median cloud lifetimes between 1.4 and 3.9 Myr. At all other galactocentric radii, galactic shear dominates the cloud lifecycle, and we predict that molecular clouds are dispersed on time-scales between 3 and 9 Myr, without a significant degree of star formation. Along the outer edge of the 100-pc stream, between radii of 100 and 120 pc, the time-scales for epicyclic perturbations and gravitational free-fall are similar. This similarity of time-scales lends support to the hypothesis that, depending on the orbital geometry and timing of the orbital phase, cloud collapse and star formation in the 100-pc stream may be triggered by a tidal compression at pericentre. Based on the derived time-scales, this should happen in approximately 20 per cent of all accretion events onto the 100-pc stream.

description: We consider a two-point correlator in massless $ϕ^3$ model within the ladder approximation . The spectral density of the correlator is known explicitly and does not contain any resonances. Meanwhile making use of the standard sum rules technique with a simple "resonance + continuum" model of the spectrum allows to predict parameters of the "resonance" very accurately in the sense that all necessary criteria of stability are perfectly satisfied.

description: The paper aims at stimulating pedagogical reflections on the relationship between grandfathers and grandsons. Following the changes due to the lengthening of life, social transformations, to the nuclearization of the family, and the changes in working, which affect parenting, grandparents return to be considered “human capital”: providers of services and tangible and intangible works, in formal and non-formal contexts, in favor of the social community, with a strong reference to inter-generational ties, including grandchildren’s care and education. The paper also includes the epistemological analysis and empirical outcomes of the exploratory research conducted. From the conclusions, multiple pedagogical declinations arise; however, a common trait emerges: that between grandparents and grandchildren proves to be, in any case, a “special” relationship.
