description: This paper presents nonlinear iterative methods for the fundamental thermal radiative transfer (TRT) model defined by the time-dependent multifrequency radiative transfer (RT) equation and the material energy balance (MEB) equation. The iterative methods are based on the nonlinear projection approach and use multiple grids in photon frequency. They are formulated by the high-order RT equation on a given grid in photon frequency and low-order moment equations on a hierarchy of frequency grids. The material temperature is evaluated in the subspace of the lowest dimensionality from the MEB equation coupled to the effective grey low-order equations. The algorithms apply various multigrid cycles to visit frequency grids. Numerical results are presented to demonstrate convergence of the multigrid iterative algorithms in TRT problems with large number of photon frequency groups.

description: It is well-established that Whitham's modulation equations approximate the dynamics of slowly varying periodic wave trains in dispersive systems. We are interested in its validity in dissipative systems with a conservation law. The prototype example for such a system is the generalized Ginzburg-Landau system that arises as a universal amplitude system for the description of a Turing-Hopf bifurcation in spatially extended pattern-forming systems with neutrally stable long modes. In this paper we prove rigorous error estimates between the approximation obtained through Whitham's modulation equations and true solutions to this Ginzburg-Landau system. Our proof relies on analytic smoothing, Cauchy-Kovalevskaya theory, energy estimates in Gevrey spaces, and a local decomposition in Fourier space, which separates center from stable modes and uncovers a (semi)derivative in front of the relevant nonlinear terms.

description: We present a new random approximation method that yields the existence of a discrete Beurling prime system $\mathcal{P}=\{p_{1}, p_{2}, \dotso\}$ which is very close in a certain precise sense to a given non-decreasing, right-continuous, nonnegative, and unbounded function $F$. This discretization procedure improves an earlier discrete random approximation method due to H. Diamond, H. Montgomery, and U. Vorhauer [Math. Ann. 334 (2006), 1-36], and refined by W.-B. Zhang [Math. Ann. 337 (2007), 671-704].
 We obtain several applications. Our new method is applied to a question posed by M. Balazard concerning Dirichlet series with a unique zero in their half plane of convergence, to construct examples of very well-behaved generalized number systems that solve a recent open question raised by T. Hilberdink and A. Neamah in [Int. J. Number Theory 16 05 (2020), 1005-1011], and to improve the main result from [Adv. Math. 370 (2020), Article 107240], where a Beurling prime system with regular primes but extremely irregular integers was constructed.

description: Recently, \citet{vitral2021does} detected a central concentration of dark objects in the core-collapsed globular cluster NGC 6397, which could be interpreted as a subcluster of stellar-mass black holes. However, it is well established theoretically that any significant number of black holes in the cluster would provide strong dynamical heating and is fundamentally inconsistent with this cluster's core-collapsed profile. Claims of intermediate-mass black holes in core-collapsed clusters should similarly be treated with suspicion, for reasons that have been understood theoretically for many decades. Instead, the central dark population in NGC 6397 is exactly accounted for by a compact subsystem of white dwarfs, as we demonstrate here by inspection of a previously published model that provides a good fit to this cluster. These central subclusters of heavy white dwarfs are in fact a generic feature of core-collapsed clusters, while central black hole subclusters are present in all {\em non\/}-collapsed clusters.

description: Behavioral homogeneity is often critical for the functioning of network systems of interacting entities. In power grids, whose stable operation requires generator frequencies to be synchronized--and thus homogeneous--across the network, previous work suggests that the stability of synchronous states can be improved by making the generators homogeneous. Here, we show that a substantial additional improvement is possible by instead making the generators suitably heterogeneous. We develop a general method for attributing this counterintuitive effect to converse symmetry breaking, a recently established phenomenon in which the system must be asymmetric to maintain a stable symmetric state. These findings constitute the first demonstration of converse symmetry breaking in real-world systems, and our method promises to enable identification of this phenomenon in other networks whose functions rely on behavioral homogeneity.

A big bad wolf in sheep’s clothing. Case studies of accounts of sexual abuse from trials taking place during the early 1900s

Subjects: History of sexual abuses, rape trials in the early 1900s, criminal Court of Naples, sexual Violence and public opinion.

description: The aim of this paper is to analyze by means of historical case studies, the reaction of the common people in urbanized Southern Italy at the beginning of the 1900s on discovering criminal behavior which for convenience sake, I define as ‘sexual abuse’. In this sense I have outlined the proceedings relative to trials for “libidinous acts”, “rape”, “indecent behavior” concerning children, in act at the Tribunal of Naples. Our case studies seem to renege the idea, widely diffused, of a female world, belonging above all to the working class, incapable of reacting publicly to sexual violence. The cases selected involve victims and the accused who live in the same building, in the same street or nearby in the same neighborhood. Issues in our paper concern how children were protected in the event of effective or attempted violence. How in the neighborhood ‘gossip’ was spread relative to the abuse, what effectively triggered police intervention and finally, how the neighborhood reacted as concerns the victim or the accused and the prejudice emerging from the documents reporting the Court proceedings. By means of the documents relative to the trial proceedings, a preliminary analysis can be put in place in order ascertain the way in which the narration of sexual crime is constructed according to the evidence of the various witnesses, summoned to court by the Authorities. Such evidence ranges from and includes the version of the accused and that of the victim to that of the witnesses, from red tape jargon expressed in the language of the Court Minutes to the scientific lexicon of medical-legal reports which all concur in tracing the outlines of an event that reflects facets of life experience and consequently, of socio-cultural history.
As concerns the reactions following the discovery of the abuse, it is possible to delineate models of behavior which are more or less constant. Above all during the period immediately following the discovery of the episode, word of mouth seems to involve mainly the women of the neighborhood. In the reconstruction of the narration of the sexual abuse, women emerge as the protagonists at crucial moments: they provide first aid, they carry out perfunctory ‘check ups’ on the victim, help the mothers to find a doctor to verify and attest the circumstance in the event of a formal complaint and the type of abuse and harm suffered.

description: The work analyses the short and long-term consequences of intimate partner violence and the strategies that women have developed to get out of violence. A causal model is developed to analyse five different multivariate dimensions characterising intimate partner violence, based on the last and unique national representative population survey about violence against women. In a second step the stories of repeated violence will be analysed focusing on the strategies the victims have used to cope with violence. The most effective strategies will be contrasted with the less ones. Less effective strategies are associated with an increasing risk of the cycle of violence, that is those who have suffered violence as a child are likely to accept it enduring in their adult life.
The analysis of the physical, moral and psychological consequences, shows a mixed picture, linked to both the severity of the violence, and to the type of suffered violence; focusing on the history of violence, the various strategies to cope with it are closely linked to the framework of severity, to the characteristics and dynamics of the violence and to the specific history that each woman lives.

The need of disclosure and protection of the women victims of violence is also enlightened. A further aim of this contribution is to discuss some principles for the clinical and therapeutic listening and treatment directed to services and shelters since this form of violence is generally underestimated, silenced, and denied. It finally introduces some principles of institutional mediation and re-negotiation of emotional bonds that refer to the Neapolitan Centro per le Famiglie’s experience.

description: We consider Lie algebras admitting an ad-invariant metric, and we study the problem of uniqueness of the ad-invariant metric up to automorphisms. This is a common feature in low dimensions, as one can observe in the known classification of nilpotent Lie algebras of dimension $\leq 7$ admitting an ad-invariant metric. We prove that uniqueness of the metric on a complex Lie algebra $\mathfrak{g}$ is equivalent to uniqueness of ad-invariant metrics on the cotangent Lie algebra $T^*\mathfrak{g}$; a slightly more complicated equivalence holds over the reals. This motivates us to study the broader class of Lie algebras such that the ad-invariant metric on $T^*\mathfrak{g}$ is unique.
 We prove that uniqueness of the metric forces the Lie algebra to be solvable, but the converse does not hold, as we show by constructing solvable Lie algebras with a one-parameter family of inequivalent ad-invariant metrics. We prove sufficient conditions for uniqueness expressed in terms of both the Nikolayevsky derivation and a metric counterpart introduced in this paper.
 Moreover, we prove that uniqueness always holds for irreducible Lie algebras which are either solvable of dimension $\leq 6$ or real nilpotent of dimension $\leq 10$.

description: We propose a posterior for Bayesian Likelihood-Free Inference (LFI) based on generalized Bayesian inference. To define the posterior, we use Scoring Rules (SRs), which evaluate probabilistic models given an observation. In LFI, we can sample from the model but not evaluate the likelihood; hence, we employ SRs which admit unbiased empirical estimates. We use the Energy and Kernel SRs, for which our posterior enjoys consistency in a well-specified setting and outlier robustness. We perform inference with pseudo-marginal (PM) Markov Chain Monte Carlo (MCMC) or stochastic-gradient (SG) MCMC. While PM-MCMC works satisfactorily for simple setups, it mixes poorly for concentrated targets. Conversely, SG-MCMC requires differentiating the simulator model but improves performance over PM-MCMC when both work and scales to higher-dimensional setups as it is rejection-free. Although both techniques target the SR posterior approximately, the error diminishes as the number of model simulations at each MCMC step increases. In our simulations, we employ automatic differentiation to effortlessly differentiate the simulator model. We compare our posterior with related approaches on standard benchmarks and a chaotic dynamical system from meteorology, for which SG-MCMC allows inferring the parameters of a neural network used to parametrize a part of the update equations of the dynamical system.

description: In this paper we present the results of the last stage of the research project Empower Daphne that involved the participation of six countries belonging to the EU in two phases: I) validation of the theoretical model on which basis rests the construct of well-being and spontaneity; II) analysis of Morenian psychodrama intervention efficacy. 407 university students were part of the non-clinical sample in the first phase and 136 women victims of domestic violence made up the clinical sample for the second phase. During the six month the women took part in psychodramatic sessions, together with individual interviews. At the beginning and the end of the six month, a questionnaire was administered consisting of a well-being and a spontaneity scales. In the article we present the results that compare well-being and spontaneity between clinical and non-clinical samples, and between the clinical cut-off scores highlighted in the literature and the scores of clinical sample. The findings demonstrate interesting differences between two sample: observed lower levels of spontaneity and well-being in women victims of domestic violence, both before and after the psychodramatic intervention.

description: Multipartite quantum system is complex. Characterizing the relations among the three bipartite reduced density operators $ρ_{AB}$, $ρ_{AC}$ and $ρ_{BC}$ of a tripartite state $ρ_{ABC}$ has been an open problem in quantum information. One of such relations has been reduced by [Cadney et al, LAA. 452, 153, 2014] to a conjectured inequality in terms of matrix rank, namely $r(ρ_{AB}) \cdot r(ρ_{AC})\ge r(ρ_{BC})$ for any $ρ_{ABC}$. It is denoted as open problem $41$ in the website "Open quantum problems-IQOQI Vienna". We prove the inequality, and thus establish a complete picture of the four-party linear inequalities in terms of the $0$-entropy. Our proof is based on the construction of a novel canonical form of bipartite matrices under local equivalence. We apply our result to the marginal problem and the extension of inequalities in the multipartite systems, as well as the condition when the inequality is saturated.

description: The present study aims to highlights the role of work group culture and gender diversity on work group functioning. Gender diversity is an aspect of organizational life and research on the effect of workgroup composition has yielded ambiguous results. The categorization elaboration model (van Knippenberg, De Dreu & Homan, 2004) addresses this issue and suggests examining factors influencing the relationship between work group diversity and work group functioning. The present study proposes that the group gender diversity affects group identification and that this effect is contingent on group norms. 18 work groups in an information technology enterprise were involved. Results confirmed the hypothesis. Theoretical and practical implications are discussed.

description: We consider the nonlinear stability of spectrally stable periodic waves in the Lugiato-Lefever equation (LLE), a damped nonlinear Schrödinger equation with forcing that arises in nonlinear optics. So far, nonlinear stability of such solutions has only been established against co-periodic perturbations by exploiting the existence of a spectral gap. In this paper, we consider perturbations which are localized, i.e., integrable on the line. Such localized perturbations naturally yield the absence of a spectral gap, so we must rely on a substantially different method with origins in the stability analysis of periodic waves in reaction-diffusion systems. The relevant linear estimates have been obtained in recent work by the first three authors through a delicate decomposition of the associated linearized solution operator. Since its most critical part just decays diffusively, the nonlinear iteration can only be closed if one allows for a spatio-temporal phase modulation. However, the modulated perturbation satisfies a quasilinear equation yielding an apparent loss of regularity. To overcome this obstacle, we incorporate tame estimates on the unmodulated perturbation, which satisfies a semilinear equation in which no derivatives are lost, yet where decay is too slow to close an independent iteration scheme. We obtain nonlinear stability of periodic steady waves in the LLE against localized perturbations with precisely the same decay rates as predicted by the linear theory.

This article investigates what social costs drove the state to pass only one of the two anti-discrimination treaties. It finds that the state perceives the race convention to be less socially costly than the gender statute’s objective mandates in regards to content about social and cultural patterns, family planning resources, and in tensions about the proposed reservations, understandings, and declarations.

description: The need of a gender perspective addressed to tackle violence against women also in psychology is argued Several terms used to name partner violence against women are discussed: from crime of passion to macho violence crossing intimate partner violence. Gender perspective in psychological intervention and research is also discussed. Social development of violence against women as a problem is described. This development has moved from silence as far as social intolerance and sensitivity to survivors. This visibility of hidden violence against women has been a lot of principal actresses in different levels and spheres. Their outcomes have been a lot of women’s liberation and recovery from violence setting during the last twenty years and the actual preserved strength of gender perspective.

description: In this paper, we establish some modified defect relations for the Gauss map $g$ of a complete minimal surface $S\subset\mathbb R^m$ into a $k$-dimension projective subvariety $V\subset\mathbb P^n(\mathbb C)\ (n=m-1)$ with hypersurfaces $Q_1,\ldots,Q_q$ of $\mathbb P^n(\mathbb C)$ in $N$-subgeneral position with respect to $V\ (N\ge k)$. In particular, we give the upper bound for the number $q$ if the image $g(S)$ intersects each hypersurfaces $Q_1,\ldots,Q_q$ a finite number of times and $g$ is nondegenerate over $I_d(V)$, where $d=lcm(°Q_1,\ldots,°Q_q)$, i.e., the image of $g$ is not contained in any hypersurface $Q$ of degree $d$ with $V\not\subset Q$. Our results extend and generalize the previous results for the case of the Gauss map and hyperplanes in a projective space. The results and the method of this paper have been applied by some authors to study the unicity problem of the Gauss maps sharing families of hypersurfaces.

What is the resonant state in open quantum systems?

description: The article reviews the theory of open quantum system from a perspective of the non-Hermiticity that emerges from the environment with an infinite number of degrees of freedom. The non-Hermiticity produces resonant states with complex eigenvalues, resulting in peak structures in scattering amplitudes and transport coefficients. After introducing the definition of resonant states with complex eigenvalues, we answer typical questions regarding the non-Hermiticity of open quantum systems. What is the physical meaning of the complex eigenmomenta and eigenenergies? How and why do the resonant states break the time-reversal symmetry that the system observes? Can we make the probabilistic interpretation of the resonant states with diverging wave functions? What is the physical meaning of the divergence of the wave functions? We also present an alternative way of finding resonant states, namely the Feshbach formalism, in which we eliminate the infinite number of the environmental degrees of freedom. In this formalism, we attribute the non-Hermiticity to the introduction of the retarded and advanced Green's functions.

description: The following paper has been realized with regard to the (con)textual construction of violence and power in total institutions. Furthermore the affective role of relations has been investigated in order to understand how concepts, such as power and violence, are situated within the relational frame of everyday interactions. The topic of the research has been focused on transgender prisoners, detained in a special section of the female ward of the prison of Florence-Sollicciano. Interviewees with prison’s staff and MtF transgender inmates have been gathered, concerning to the way how gender identity claims in a highly institutionalized context. Qualitative analysis, adopting the software Transana, has been used in order to study the implicit sense of ideological, historical and relational meanings within discursive production. Results show that everyday interactions, such as between trans-prisoners themselves and amongst them and the penitentiary guards, increase the affective value of communication and consequently of interpersonal relations. The affective variable, therefore, becomes an important aspect, according to which interaction can be considered  pragmatic and situated actions. Empowering the pragmatical and strategical value of situated relations improves not only the difficult condition of detention, but also the hard and challenging tasks a those staff-members, who work in prison every day.

A new approach to the central gravitational field in vacuum space / Implementation of General Relativity in finite space to the MOND theory

description: We know, from the publication of the Schwarzschild metric (1916) and the Birkhoff’s theorem (1923) that a central symmetric gravitational field in infinite vacuum space is automatically static in the framework of General Relativity. This result has intrigued many researchers. Indeed, Lemaitre’s works seemed to suggest that the dynamic behavior of a metric could be inherent to General Relativity. We have searched for a method allowing getting round the Birkhoff’s theorem, and we have finally found the following methodology: For defining the metric of a central gravitational field in vacuum, we have started from an undefined metric written in tortoise coordinates, instead of starting from an undefined metric written in the coordinates used by Schwarzschild. In tortoise coordinates, the solution obtained by canceling the Ricci tensor depends on two arbitrary functions, the first one being a function of (t+r), and the second one being a function of ( t−r) (t being the temporal coordinate multiplied by the speed light, and r being the radial coordinate). In a first approach, it appears that some convenient transformations (if well justified) of coordinates lead to the classical Schwarzschild metric, whatever arbitrary functions used. However, we have found that if we choose for the arbitrary functions a triangular signal, the situation changes dramatically: in this case, the coordinates t and r permute their temporal/spatial role over time; the metric is broken down in four different versions which replace each other cyclically over time. Consequently, it becomes impossible to find a general transformation of coordinates allowing recovering the Schwarzschild metric. This new metric describes an area in which the orbital velocity of a massive particle does not depend on the radial distance; this result allows recovering the Tully-Fisher law without any dark matter; we find also that the Riemannian space-time curvature is oscillatory. So, we came up with our methodology to find, in the framework of General Relativity, a new solution for the central gravitational field in vacuum space, which is considered currently as impossible; more, this solution could be physical, as it explains the Tully-Fisher law without any dark matter. By combining this new metric and the classical Schwarzschild metric, it becomes possible to justify approximately in a galaxy the velocity profile of stars found in the MOND theory, without any dark matter, in the framework of General Relativity.

Limits for realizing single photons

description: Exact single photons cannot be generated on demand due to their infinite tails. To quantify how close realizable optical states can be to some target single photon in one dimension, we argue that there are two natural but incompatible ways to specify the target state. Either it can be expressed as a photon with a chosen positive-frequency spectrum, or it can be described as an (unphysical) photon in a chosen positive-time pulse. The results show that for sufficiently short target pulses, the closest realizable states contain substantial multiphoton components. Upper and lower bounds for the maximum fidelity are derived and are expressed as functions of the size of the target state's tail, for negative time or negative frequency, respectively. We also generalize the bounds to arbitrary photon-number states.

The pectoral cross was commonly worn by bishops and abbots in the medieval period. The figure style and the particular iconographic feature of the Dextera Dei also link the cross with monumental pre-Conquest stone sculptures, such as Stepney and Romsey, datable to the late 10th or early 11th century.
