description: A detailed study of the geometries that emerge by a gravitating generalized Yang monopole in even dimensions is carried out. In particular, those which present black hole and cosmological horizons. This two-horizon system is thermally unstable. The process of thermalization will drive both horizons to coalesce. This limit is what is profusely studied in this paper. It is shown that eventhough coordinate distance shrinks to zero, physical distance does not. So, there is some remaining space which geometry has been computed and identified as a generalized Nariai solution. The thermal properties of this new spacetime are then calculated. Topics, as the elliptical relation between radii of spheres in the geometry or a discussion about whether a mass-type term should be present in the line element or not, are also included.

Efficient Horizontal Mergers in Polluting Industries with Cournot Competition

Subjects: SECS-P/01 Economia politica

description: We compare a Bertrand with a Cournot duopoly in a setting where production is polluting and exploits natural resources, and firms bear convex production costs. We adopt Dastidar's (1995) approach, yielding a continuum of Bertrand-Nash equilibria ranging above marginal cost pricing also, to show that softening price competition may lead to a lower output production in a Bertrand rather than a Cournot industry. The market structure bringing about the lowest output determines the highest social welfare, given the fact that the negative
environmental effects of production more than offset the gain in consumer surplus.

description: Objective This study examined the prevalence and factors associated with depression among adolescents attending higher secondary schools in the Pokhara Metropolitan City of Nepal.Design A cross-sectional study design was adopted.Setting Four randomly selected higher secondary schools of Pokhara Metropolitan, Nepal.Participants 312 randomly sampled higher secondary school students.Methods The Center for Epidemiologic Studies Depression Scale was used to assess the level of depression among students. The data collected through a self-administered questionnaire were analysed using descriptive statistical methods such as frequency and percentage. χ2 test and unadjusted OR (UOR) were calculated to assess the statistical relationship between depression and various variables at 95% CI, with level of significance at p<0.05.Results The study found a high prevalence of depression among high school students, with more than two-fifths (44.2%) of students having depression. Furthermore, almost a quarter (25.3%) of the students were noted to have mild depression and 18.9% of the students expressed major depression. Students who had low perceived social support (UOR: 3.604; 95% CI 2.088 to 6.220), did not share their problems with anyone (UOR: 1.931; 95% CI 1.228 to 3.038) and had low self-esteem (UOR: 5.282; 95% CI 2.994 to 9.319) were at higher odds of being depressed.Conclusion A high prevalence of depression was observed among high school students. It was also observed that students’ level of perceived social support, self-esteem and help-seeking behaviour are somehow related to their mental well-being. Hence, improving social support and self-esteem may alleviate depression and mental distress among these adolescents.

description: We present a graphene-based phase shifter for radio-frequency (RF) phase-array applications. The core of the designed phase-shifting system consists of a graphene field-effect transistor (GFET) used in a common source amplifier configuration. The phase of the RF signal is controlled by exploiting the quantum capacitance of graphene and its dependence on the terminal transistor biases. In particular, by independently tuning the applied gate-to-source and drain-to-source biases, we observe that the phase of the signal, in the super-high frequency band, can be varied nearly 200 degrees with a constant gain of 2.5 dB. Additionally, if only the gate bias is used as control signal, and the drain is biased linearly dependent on the former (i.e., in a completely analogue operation), a phase shift of 85 degrees can be achieved making use of just one transistor and keeping a gain of 0 dB with a maximum variation of 1.3 dB. The latter design can be improved by applying a balanced branch-line configuration showing to be competitive against other state-of-the-art phase shifters. This work paves the way towards the exploitation of graphene technology to become the core of active analogue phase shifters for high-frequency operation.

description: We present measurements of the infrared response of the quasi-one-dimensional organic conductor (TMTSF)2$SO3 along (E||a) and perpendicular (E||b') to the stacking axis as a function of temperature. Above the metal-insulator transition related to the anion ordering the optical conductivity spectra show a Drude-like response. Below the transition an energy gap of about 1500 cm-1 (185 meV) opens, leading to the corresponding charge transfer band in the optical conductivity spectra. The analysis of the infrared-active vibrations gives evidence for the long-range crystal structure modulation below the transition temperature and for the short-range order fluctuations of the lattice modulation above the transition temperature. Also we report about a new infrared mode at around 710 cm-1 with a peculiar temperature behavior, which has so far not been observed in any other (TMTSF)2X salt showing a metal-insulator transition. A qualitative model based on the coupling between the TMTSF molecule vibration and the reorientation of electrical dipole moment of the FSO3 anion is proposed, in order to explain the anomalous behavior of the new mode.

description: Machine learning can be defined as a comprehensive range of tools utilized for recognizing patterns in data. Owing to its reliance on artificial intelligence in lieu of age-old, traditional methods, machine learning has established itself as an exceedingly quicker way of discerning patterns and trends from bulk data. The advanced system can even update itself on the availability of new data. This paper intends to elucidate different techniques involved in machine learning that have facilitated the prediction, detection and restriction of infectious diseases in the past few decades. Moreover, in light of the unprecedented COVID-19 pandemic, such tools and techniques have been utilized extensively by smart cities to curb the proliferation of the SARS-CoV-2 virus. However, the strengths and weaknesses of this approach remain abstruse and therefore, this review also aims to evaluate the role of machine learning in the recent coronavirus outbreak.

description: New observational data of neutron stars since GW170817 have helped improve our knowledge about nuclear symmetry energy especially at high densities. We have learned particularly: (1) The slope parameter $L$ of nuclear symmetry energy at saturation density $ρ_0$ of nuclear matter from 24 new analyses is about $L\approx 57.7\pm 19$ MeV at 68\% confidence level consistent with its fiducial value, (2) The curvature $K_{\rm{sym}}$ from 16 new analyses is about $K_{\rm{sym}}\approx -107\pm 88$ MeV, (3) The magnitude of nuclear symmetry energy at $2ρ_0$, i.e. $E_{\rm{sym}}(2ρ_0)\approx 51\pm 13$ MeV at 68\% confidence level, has been extracted from 9 new analyses of neutron star observables consistent with results from earlier analyses of heavy-ion reactions and the latest predictions of the state-of-the-art nuclear many-body theories, (4) while the available data from canonical neutron stars do not provide tight constraints on nuclear symmetry energy at densities above about $2ρ_0$, the lower radius boundary $R_{2.01}=12.2$ km from NICER's very recent observation of PSR J0740+6620 of mass $2.08\pm 0.07$ $M_{\odot}$ and radius $R=12.2-16.3$ km at 68\% confidence level sets a tight lower limit for nuclear symmetry energy at densities above $2ρ_0$, (5) Bayesian inferences of nuclear symmetry energy using models encapsulating a first-order hadron-quark phase transition from observables of canonical neutron stars indicate that the phase transition shift appreciably both the $L$ and $K_{\rm{sym}}$ to higher values but with larger uncertaintie , (6) The high-density behavior of nuclear symmetry energy affects significantly the minimum frequency necessary to rotationally support GW190814's secondary component of mass (2.50-2.67) $M_{\odot}$ as the fastest and most massive pulsar discovered so far.

description: COVID-19 pandemic has shaken the roots of healthcare facilities worldwide, with the US being one of the most affected countries irrespective of being a superpower. Along with the current pandemic, COVID-19 can cause a secondary crisis of mental health pandemic if left unignored. Various studies from past epidemics, financial turmoil and pandemic, especially SARS and MERS, have shown a steep increase in mental and psychological issues like depression, low quality of life, self-harm and suicidal tendencies among general populations. The most venerable being the individuals infected and cured due to social discrimination. The government is taking steps to contain and prevent further infections of COVID-19. However, the mental and psychological wellbeing of people is still left ignored in developing countries like India. There is a significant gap in India concerning mental and psychological health still being stigmatized and considered 'non-existent'. This study's effort is to highlight the importance of mental and psychological health and to suggest interventions based on positive psychology literature. These interventions can support the wellbeing of people acting as a psychological first aid.

description: Supernova remnants are likely to be the accelerators of the galactic cosmic rays. Assuming the correctness of this hypothesis, we develop a method to extract the parent cosmic ray spectrum from the VHE gamma ray flux emitted by supernova remnants (and other gamma transparent sources). Namely, we calculate semi-analytically the (inverse) operator which relates an arbitrary gamma ray flux to the parent cosmic ray spectrum, without relying on any theoretical assumption about the shape of the cosmic ray and/or photon spectrum. We illustrate the use of this technique by applying it to the young SNR RX J1713.7-3946 which has been observed by H.E.S.S. experiment during the last three years. Specific implementations of the method permit to use as an input either the parameterized VHE gamma ray flux or directly the raw data. The possibility to detect features in the cosmic rays spectrum and the error in the determination of the parent cosmic ray spectrum are also discussed.

description: New physics beyond the Standard Model can lead to extra matter effects on neutrino oscillation if the new interactions distinguish among the three flavors of neutrino. In Ref.1, we argued that a long-baseline neutrino oscillation experiment in which the Fermilab-NUMI beam in its high-energy mode is aimed at the planned Hyper-Kamiokande detector would be capable of constraining the size of those extra matter effects, provided the vacuum value of \sin^2 2θ_{23} is not too close to one. In this talk, we discuss how such a constraint would translate into limits on the coupling constants and masses of new particles in models such as topcolor assisted technicolor.

description: Dust is believed to form in the circumstellar envelope around the Asymptotic Giant Branch (AGB) and Red Supergiant (RSG) stars. The formation and evolution of circumstellar dust could be affected by the radiative and mechanical feedback. In this poster, we showed that the intense radiation from evolved stars could modify the grain-size distribution through the RAdiative Torque Disruption (RATD) mechanism. Then we modelled the extinction curve of the Betelgeuse envelope as a case study. Our model showed that the extinction decreases at near-UV, optical, and infrared wavelengths while increasing at far-UV wavelengths due to the abundance of small grains produced by the RATD mechanism. The consequent flux well reproduced the observations from the near-UV to near-IR range, which suggested the scenario of driving stellar winds by smaller grains a < 0.1 um. Our model can be used to explain dust extinction and reddening in other RSG/AGB spectra.

description: The nature of the main constituents of the mass of the universe is one of the outstanding riddles of cosmology and astro-particle physics. Current models explaining the evolution of the universe, and measurements of the various components of its mass, all have in common that an appreciable contribution to that mass is non-luminous and non-baryonic, and that a large fraction of this so-called dark matter must be in the form of non-relativistic massive particles (Cold Dark Matter: CDM). In the spirit of the Lake Louise Winter Institute Lectures we take a look at the latest astronomical discoveries and report on the status of direct and indirect Dark Matter searches.

Publisher: name: Moving the Social

description: The notion of “1968” as an expression of civil disorder in western countries is primarily attributed to students, but also to young people in general. This article pays special attention to the group of wage earners, as the biggest population group, and especially to the youth, that was organized in trade unions. The reason for putting young trade unionists from “1968” under closer consideration lies in the significant shift to the left, by which German trade unions were captured during these times. It will be asked why this shift happened and how it was linked to the protests at this time. In addition, the contribution analyses the trade unions attitude towards the 1968-movement – and the roles that have been played by young trade unionists. It is argued, that according to a general radicalisation in “1968”, similar tendencies can also be observed in the trade union youth in general though substantial variation cannot be overlooked.

description: By using terms and methods of historical research on social mobility, this essay looks at patterns of inter-generational mobility of elementary school teachers in North Rhine- Westphalia after World War II. The discussion focuses on the long-term historical changes in the social recruitment of teachers in the course of the 20th century, considering the enormous professionalization of the working field. Previous research has stated that teaching offered vast opportunities for upward career advancements at the beginning of the 20th century. In contrast to other contemporary opinions, professionalization did not lead to a bigger social exclusiveness. Furthermore, the work of elementary school teachers in Germany and in North Rhine-Westphalia in the 20th century was characterized by high rates of upward mobility. In 1971/72 two thirds of future teachers came from lower social classes than the profession itself was said to belong to. Opportunities for upward mobility to this extent can be referred to the results of the expansion of education. Especially the occupation of elementary school teachers became increasingly more accessible to children of the working class. Overall, the occupation of elementary school teachers went through a transformation in the 20th century.

A mathematical framework for polarization algebra of deterministic optical systems

description: Abstract: In general, Jones formalism of polarization optics refers to deterministic optical systems represented by  $2\times2$ complex Jones matrices acting on totally polarized light states represented by two dimensional complex Jones vectors. On the other hand, Stokes-Mueller formalism deals only with real states, hence it cannot account for phases introduced by optical systems. But, Stokes-Mueller formalism has an advantage over the Jones formalism that it works with directly measurable parameters, therefore it is desirable to merge these two approaches into a single formalism that links the real-measurable states with complex states. In previous works it was shown that there exists a $4\times4$ complex matrix that can keep track of the phase introduced by the deterministic optical system. This complex matrix transforms real Stokes vectors into four dimensional complex vectors related with phase. Recently a theorem was introduced. The theorem states that, for deterministic optical systems, there exists a relation between the outer products of  real-measurable input-output Stokes vectors and four dimensional complex state vectors of totally polarized light. In this note these results are combined in a compact mathematical framework.

Deep and wide umbilicus, ovoid aperture, about 0.60 -0.80 mm high and 0.51 -0.66 mm wide, slightly oblique, and having a sharp peristome, slightly reflected towards the columella, and strongly towards the outer lip. Last whorl represents 90 % of total height. Corneum operculum, with orange to yellow coloration, convex in the inner side (see Fig. 1E, 3D).
Animal: The animal is colorless, and the eyes are missing. The penis is broad and rounded at the tip with a penial lobe of the same length (Fig. 3B). Intestine with one loop (Fig. 3C). Female sex tract with spherical bursa, receptaculum could not be found.
Etymology: The specific name refers to the helmetshape of the shell, resembling the M15 Adrian French model of World War I.
Dimensions: The holotype is 1.05 mm in diameter and 0.68 mm in height. Paratypes range from 0.96 - 1.27 mm in diameter and 0.51 - 0.74 mm in height (see Table I).
Habitat: Stygobiotic, all the shells were collected from sediments at the opening of the springs.
Distribution: Only known from two different springs, very close to each other, in the margins of the Fluvià River.
Differentiating characters: Vilertia gen. nov. differs from all valvatoid genera by the reflexed peristome. It differs from Rifia Ghamizi 2020 by the missing outgrowth at the operculum; from Fissuria Boeters, 1991, by the penis, which is papillose but without a penial lobe. In addition, Fissuria has two intestinal loops, while Vilertia gen. nov. has only one.

description: We model the effects of collisions and close encounters on the stellar populations observed in the Milky Way nuclear stellar cluster (NSC). Our analysis is based on $N$-body simulations in which the NSC forms by accretion of massive stellar clusters around a supermassive black hole. We attach stellar populations to our $N$-body particles and follow the evolution of their stars, and the rate of collisions and close encounters. The most common encounters are collisions between pairs of main-sequence stars, which lead to mergers: destructive collisions between main-sequence stars and compact objects are rare. We find that the effects of collisions on the stellar populations are small for three reasons. First, our models possess a core which limits the maximum stellar density. Secondly, the velocity dispersion in the NSC is similar to the surface escape velocities of the stars, which minimises the collision rate. Finally, whilst collisions between main-sequence stars destroy bright giants by accelerating their evolution, they also create them by accelerating the evolution of lower-mass stars. These two effects approximately cancel out. We also investigate whether the G2 cloud could be a fuzzball: a compact stellar core which has accreted a tenuous envelope in a close encounter with a red giant. We conclude that fuzzballs with cores below $2\,M_\odot$ have thermal times-scales too short to reproduce G2. A fuzzball with a black-hole core could reproduce the surface properties of G2 but the production rate of such objects in our model is low.

description: There is a class of binary post-AGB stars with a remarkable near-infrared excess that are surrounded by Keplerian or quasi-Keplerian disks and extended outflows composed of gas escaping from the disk. The Keplerian dynamics had been well identified in four cases, namely the Red Rectangle, AC Her, IW Car, and IRAS 08544-4431. In these objects, the mass of the outflow represents ~ 10 % of the nebular mass, the disk being the dominant component of the nebula. We present interferometric NOEMA maps of 12CO and 13CO J=2-1 in 89 Her and 12CO J=2-1 in AC Her, IRAS 19125+0343, and R Sct. Several properties of the nebula are obtained from the data and model fitting, including the structure, density, and temperature distributions, as well as the dynamics. We also discuss the uncertainties on the derived values. The presence of an expanding component in AC Her is doubtful, but thanks to new maps and models, we estimate an upper limit to the mass of this outflow of < 3 10^-5 Mo, that is, the mass of the outflow is < 5 % of the total nebular mass. For 89 Her, we find a total nebular mass of 1.4 10^-2 Mo, of which ~ 50 % comes from an hourglass-shaped extended outflow. In the case of IRAS 19125+0343, the nebular mass is 1.1 10^-2 Mo, where the outflow contributes ~ 70 % of the total mass. The nebular mass of R Sct is 3.2 10^-2 Mo, of which ~ 75 % corresponds to a very extended outflow that surrounds the disk. Our results for IRAS 19125+0343 and R Sct lead us to introduce a new subclass of binary post-AGB stars, for which the outflow is the dominant component of the nebula. Moreover, the outflow mass fraction found in AC Her is smaller than those found in other disk-dominated binary post-AGB stars. 89 Her would represent an intermediate case between both subclasses.

description: We present a nonperturbative quasi-classical theory of graphene photoconductivity. We consider the influence of low-frequency (microwave, terahertz, mid-infrared) radiation on the static conductivity of a uniform graphene layer and calculate its photoconductivity as a function of frequency, polarization and strength of the external ac electric field, as well as on the material properties (electron density, scattering time) and temperature. The theory is valid at frequencies $\hbarω\lesssim 2E_F$ and at arbitrarily strong ac electric fields. We compare our results with those of the third-order perturbation theory and determine the applicability range of the perturbative solutions.

description: We perform a binary population synthesis calculation incorporating very massive population (Pop.) III stars up to 1500 $M_\odot$, and investigate the nature of binary black hole (BBH) mergers. Above the pair-instability mass gap, we find that the typical primary black hole (BH) mass is 135-340 $M_\odot$. The maximum primary BH mass is as massive as 686 $M_\odot$. The BBHs with both of their components above the mass gap have low effective inspiral spin $\sim$ 0. So far, no conclusive BBH merger beyond the mass gap has been detected, and the upper limit on the merger rate density is obtained. If the initial mass function (IMF) of Pop. III stars is simply expressed as $ξ_m(m) \propto m^{-α}$ (single power law), we find that $α\gtrsim 2.8$ is needed in order for the merger rate density not to exceed the upper limit. In the future, the gravitational wave detectors such as Einstein telescope and Pre-DECIGO will observe BBH mergers at high redshift. We suggest that we may be able to impose a stringent limit on the Pop. III IMF by comparing the merger rate density obtained from future observations with that derived theoretically.

L’assentificazione dell’oggetto e la presentificazione del soggetto nelle opere teatrali di Sarah Kane
Creators: name: Fuoco, Ester

description: Art as an organization of the empty is a theory that shows a deep affinity to the psychoanalytical processes suggested by Sigmund Freud and Jacques Lacan. Indeed, the artistic experience cannot avoid the vacuum limit or circumscribe it. Art does not omit nor does it fill the need, or absence of this need, though it could outline and border it. The works written by the British playwright Sarah Kane, a spokesperson for the experiential theatre dominated by an aesthetic limit and excess, demonstrate the theory that there is nothing impossible to represent on stage. In fact a symbolic treatment of the real in which the inability to represent the Thing (according to the Lacanian definition) becomes the same condition of a possible representation. The assentification of the object is closely correlated to a subject's presentification. In her works Sarah Kane, expresses the notion of a collision such as a Stoss, named by Heidegger in The Origin of the Work of Art, in which the aesthetic experience together with anguish and death, is aimed at keeping alive the sense of disorientation which is a constituent factor and provisional of being in the world, Daseing.

Contribution of dipolar bridging to phospholipid membrane interactions: a mean-field analysis

description: We develop a model of interacting zwitterionic membranes with rotating surface dipoles immersed in a monovalent salt, and implement it in a field theoretic formalism. In the mean-field regime of monovalent salt, the electrostatic forces between the membranes are characterized by a non-uniform trend: at large membrane separations, the interfacial dipoles on the opposing sides behave as like-charge cations and give rise to repulsive membrane interactions; at short membrane separations, the anionic field induced by the dipolar phosphate groups sets the behavior in the intermembrane region. The attraction of the cationic nitrogens in the dipolar lipid headgroups leads to the adhesion of the membrane surfaces via dipolar bridging. The underlying competition between the opposing field components of the individual dipolar charges leads to the non-uniform salt ion affinity of the zwitterionic membrane with respect to the separation distance; large inter-membrane separations imply anionic excess while small, nanometer size separations, favor cationic excess. This complex ionic selectivity of zwitterionic membranes may have relevant repercussions on nanofiltration and nanofluidic transport techniques.
Methodology to determine the spin-parity of muon-philic $X$ boson in $J/ψ\rightarrow μ^- μ^+ X$ decay

description: The present anomaly in muon anaomalous magnetic moment can be explained by the presence of a muon-philic $X$ boson which could be a scalar particle or a vector particle with mass less than twice the mass of muon. The muon-philic $X$ boson could interestingly not be a parity eigenstate as well. If there exists such a boson, irrespective of its parity, it can be directly observed in the decay $J/ψ\to μ^- μ^+ X$ where $X$ remains invisible. We show that by using the angular distribution or the distribution of events in the square Dalitz plot, along with two well defined dimensionless ratios, one can clearly distinguish among the various spin-parity possibilities. This would constitute an important probe of both the existence and the nature of this new physics possibility.

Die soziale, wirtschaftliche und politische Historiographie des modernen Wales
Creators: name: Hopkin, Deian R.
Publisher: name: Moving the Social
Year: 2014

description: Despite its small size, Wales has a long-established and rich cultural tradition, and this is reflected in historio-graphy, notably in Labour history. The enormous growth in the Welsh coal industry up to 1914 produced the foundations for a flourishing Labour movement which has subsequently provided much of the leadership for the British Labour and trade union movement. Historians have found considerable inspiration in this, but they have also sought to discover where the source of the Labour movements was; they found it in the dissenting and radical traditions of the eighteenth and nineteenth centuries which produced riet and upheaval as well as intellectual ferment. The diversity of Wales is also evident in the historiography, not only the contrasts between remote rurality and profound industrialism but also between ancient Welsh-language culture and the more recent and pervasive English culture. Recently, important debates have sprung up over the very meaning of the term Wales and Welshness and this debate, a spill-over from contemporary politics, is producing some of the most important new work.
