description: We study the three-dimensional gravity with torsion given by the Mielke-Baekler (MB) model coupled to gravitational Chern-Simons term, and that possess electric charge described by Maxwell-Chern-Simons electrodynamics. We find and discuss this theory's charged black holes solutions and uncharged solutions. We find that for vanishing torsion our solutions by means of a coordinate transformation can be written as three-dimensional Chern-Simons black holes. We also discuss a special case of this theory, Topologically Massive Gravity (TMG) at chiral point, and we show that the logarithmic solution of TMG is also a solution of the MB model at a fixed point in the space of parameters. Furthermore, we show that our solutions generalize Godel type solutions in a particular case. Also, we recover BTZ black hole in Riemann-Cartan spacetime for vanishing charge.

description: Relativistic charged particles (CR for cosmic-rays) produced by Supernova explosion of the first generation of massive stars that are responsible for the re-ionization of the universe escape into the intergalactic medium, carrying an electric current. Charge imbalance and induction give rise to a return current, $\vec j_t$, carried by the cold thermal plasma which tends to cancel the CR current. The electric field, $\vec E=η\vec j_t$, required to draw the collisional return current opposes the outflow of low energy cosmic rays and ohmically heats the cold plasma. Owing to inhomogeneities in the resistivity, $η(T)$, caused by structure in the temperature, $T$, of the intergalactic plasma, the electric field possesses a rotational component which sustains Faraday's induction. It is found that magnetic field is robustly generated throughout intergalactic space at rate of 10$^{-17}-10^{-16}$ Gauss/Gyr, until the temperature of the intergalactic medium is raised by cosmic reionization. The magnetic field may seed the subsequent growth of magnetic fields in the intergalactic environment.

description: Low temperature magnetoconductance measurements were made in the vicinity of the charge neutrality point. Two origins for the fluctuations were identified close to the CNP. At very low magnetic fields there exist only mesoscopic magneto-conductance quantum interference features which develop rapidly as a function of density. At slightly higher fields (> 0.5T), close to the CNP, additional fluctuations track the quantum Hall sequence expected for monolayer graphene. These additional features are attributed to effects of locally charging individual quantum Hall (QH) localized states. These effects reveal a precursor to the quantum Hall effect (QHE) since, unlike previous transport observations of QH dots charging effects, they occur in the absence of quantum Hall plateaus or Shubnikov- de Haas (SdH) oscillations. From our transport data we are able to extract parameters that characterize the inhomogeneities in our device.

description: Carnatic music traces its roots back to the ancient traditions of South India. This ancient art form has undergone the most musical and social transformation over the last few hundred years. Particularly in the realm of gender politics in India, South Indian classical music has seen a renaissance of emerging female artists over the last century. The interest of this paper is in the particular moment in history where the cultural constructs of India made it possible for women to break through barriers and emerge as eminent, sought-after artists in classical music. The emergence of female artists and the growing voice of women in gender politics issues in India during the early 20th century is a phenomenon that must have some explanation. Thus, the main research areas of this paper are, first, to establish the political and social environment of postcolonial India in which the female voice became respected in the classical arts. Second, this paper aims to understand how the female rise to popularity in the 20th century impacted the state of gender dynamics in Carnatic music in the 21st century, especially through the lens of the #MeToo movement. Finally, these research areas aim to answer one overarching question: What was the journey of the female voice in Carnatic music?

CMB data constraint on self-annihilation of dark matter particles

description: Recently, self-annihilation of dark matter particles is proposed to explain the "WMAP Haze" and excess of energetic positrons and electrons in ATIC and PAMELA results. If self-annihilation of dark matter occurs around the recombination of cosmic plasma, energy release from self-annihilation of dark matter delays the recombination, and hence affects CMB anisotropy. By using the recent CMB data, we have investigated the self-annihilation of dark matter particles. In this investigation, we do not find statistically significant evidence, and impose an upper bound on / m_chi. The upcoming data from Planck surveyor and the Fermi Gamma-ray telescope will allow us to break some of parameter degeneracy and improve constraints on self-annihilation of dark matter particles.

description: A systematic study of low energy nuclear structure at normal deformation is carried out using the Hartree-Fock-Bogoliubov theory extended by the Generator Coordinate Method and mapped onto a 5-dimensional collective quadrupole Hamiltonian. Results obtained with the Gogny D1S interaction are presented from dripline to dripline for even-even nuclei with proton numbers Z=10 to Z=110 and neutron numbers N less than 200. The properties calculated for the ground states are their charge radii, 2-particle separation energies, correlation energies, and the intrinsic quadrupole shape parameters. For the excited spectroscopy, the observables calculated are the excitation energies and quadrupole as well as monopole transition matrix elements. We examine in this work the yrast levels up to J=6, the lowest excited 0^+ states, and the two next yrare 2^+ states. The theory is applicable to more than 90% of the nuclei which have tabulated measurements. The data set of the calculated properties of 1712 even-even nuclei, including spectroscopic properties for 1693 of them, are provided in CEA website and EPAPS repository with this article \cite{epaps}.

description: We present the results of a Hubble Space Telescope (HST) study of dwarf galaxies in the outer regions of the nearby rich Perseus Cluster, down to M_V = -12, and compare these with the dwarf population in the cluster core from our previous HST imaging. In this paper we examine how properties such as the colour magnitude relation, structure and morphology are affected by environment for the lowest mass galaxies. Dwarf galaxies are excellent tracers of the effects of environment due to their low masses, allowing us to derive their environmentally based evolution, which is more subtle in more massive galaxies. We identify 11 dwarf elliptical (dE) and dwarf spheroidal (dSph) galaxies in the outer regions of Perseus, all of which are previously unstudied. We measure the (V-I)_0 colours of our newly discovered dEs, and find that these dwarfs lie on the same red sequence as those in the cluster core. The morphologies of these dwarfs are examined by quantifying their light distributions using CAS parameters, and we find that dEs in the cluster outskirts are on average more disturbed than those in the core, with =0.13\pm0.09 and =0.18\pm0.08, compared to =0.02\pm0.04, =0.01\pm0.07 for those in the core. Based on these results, we infer that these objects are ``transition dwarfs'', likely in the process of transforming from late-type to early type galaxies as they infall into the cluster, with their colours transforming before their structures. When we compare the number counts for both the core and outer regions of the cluster, we find that below M_V = -12, the counts in the outer regions of the cluster exceed those in the core. This is evidence that in the very dense region of the cluster, dwarfs are unable to survive unless they are sufficiently massive to prevent their disruption by the cluster potential and interactions with other galaxies.

Hate Speech in the Marketplace: An Economic Analysis of the Efficacy of Hate Speech Restrictions

description: The phrase ‘marketplace of ideas’ has often been invoked in arguments in favor of free speech. The metaphor is used to suggest that, in the same way that the economic marketplace naturally promotes the success of the best companies and products, a free ‘marketplace of ideas’ results in the success of the best ideas over time. In this thesis, I take a closer look at the parallels between the so-called marketplace of ideas and the economic marketplace. Specifically, I consider how various arguments for and against the restriction of hate speech can be reevaluated through the lens of economic theory. I relate perspectives on hate speech held by certain legal philosophers to the economic concepts of ‘externalities’ and ‘anticompetitive behavior.’ Ultimately, my aim is to use an economic perspective to predict the efficacy of hate speech restrictions.

description: Given a self-adjoint operator H, a self-adjoint trace class operator V and a fixed Hilbert-Schmidt operator F with trivial kernel and co-kernel, using limiting absorption principle an explicit set of full Lebesgue measure is defined such that for all points of this set the wave and the scattering matrices can be defined and constructed unambiguously. Many well-known properties of the wave and scattering matrices and operators are proved, including the stationary formula for the scattering matrix. This new abstract scattering theory allows to prove that for any trace class perturbations of arbitrary self-adjoint operators the singular part of the spectral shift function is an almost everywhere integer-valued function.

ONTOLOGY OF CONCILIARITY AND RUSSIAN PATRIOTISM

description: The authors believe that the formation of Russian patriotism, first of all, should be carried out on the basis of the principle of conciliarity. The principle of conciliarity, in fact, is the core of the Russian national consciousness. The ontology of conciliarity is built through «co-being with others», where «We-being» is primary, and «I-being» follows organically from it. This ontology differs significantly from the existential foundations of the western social order, which is oriented towards individualism. The common man is characterized by the primacy of the spiritual over the material, the willingness to sacrifice, the desire to help another. These qualities constitute the essential content of such a phenomenon as Russian patriotism. The article emphasizes that all social modifications in Russia should be carried out with a focus on the principle of conciliarity, in which case the Russian society, without losing its own uniqueness, will be viable and effective.

description: Comtraces (combined traces) are extensions of Mazurkiewicz traces that can model the "not later than" relationship. In this paper, we first introduce the novel notion of generalized comtraces, extensions of comtraces that can additionally model the "non-simultaneously" relationship. Then we study some basic algebraic properties and canonical reprentations of comtraces and generalized comtraces. Finally we analyze the relationship between generalized comtraces and generalized stratified order structures. The major technical contribution of this paper is a proof showing that generalized comtraces can be represented by generalized stratified order structures.

description: Medical humanities has existed since the 1960s, and research shows that it can improve important physician facets such as empathy, well-being, and understanding of the human condition. However, because of the challenging nature of evaluating the impact of medical humanities implementation in medical education, no single best practice for its incorporation can be identified. Medical humanities programs and curricula vary from each other wildly, and in Texas, a state with 14 medical schools, it is especially challenging for students, educators, and administrators to get a sense of what opportunities exist across the state. In this thesis, I review the existing literature regarding medical humanities education at large and interview key experts from six prominent Texas medical schools. In doing so, I explore medical humanities, its value to medical education and practice, its common programs and curricular structures, and its particular implementations within select Texas medical schools. I bring all of this information into one central location that is easy to access and navigate. This is valuable to undergraduate students navigating medical school admissions, medical students seeking opportunities at their own schools, educators seeking collaboration with other institutions or models to implement at their own, administrators curious about the inclusion of medical humanities in an already packed curriculum, and several others. I also draw attention to trends in medical humanities education in Texas medical schools and subsequently make suggestions regarding how Texas medical schools could improve upon the current state of their medical humanities education in the future. One such suggestion involves the inclusion of programs and curricula from each of an integrated-longitudinal approach, an elective-based approach, and a scholarly concentration approach.
Sexual Preference in Female Singing Mice (Scotinomys Teguina) Based on Male Song Effort

description: Females may choose males whose traits signal better genes, as well as those who demonstrate trait differences from the males a female was raised with. Additionally, female sexual preference across species varies with hormonal levels and behavioral estrus cycles. Sexual preference in females has been neglected relative to male preference, which is more robustly expressed and easier to measure in most species. Evidence on the specifics of how females choose mates is sparse, but extravagant male signaling has long been a suspected factor. Male Alston’s singing mice (Scotinomys Teguina) produce loud and elaborate songs, which they use most frequently in sexual scenarios. These songs vary in complexity: while some males are able to produce high-effort songs, others can’t afford the energy expense or predator exposure and thereby produce lower-effort songs. This study examined female preference for high or low-effort songs produced by a male. The most effective method of estrus induction was determined by varying hormone treatment methods. Young, estrus induced and validated females were tested by measuring approach and investigation behavior to high and low effort songs in a two choice test. Preference test results display strong female preference for the high effort stimuli, and may indicate a trend of females selecting “superior” males with higher energy reserves and stronger virility based on male signaling characteristics.

Using a Glauber eikonal model, we compute the p-p eccentricities, transverse areas and particle-multiplicities for various phenomenological parametrisations of the proton spatial density. For realistic proton transverse profiles, we find integrated elliptic flow v2 parameters below 3% in p-p collisions at sqrt(s) = 14 TeV.

description: Recently, several accreting M dwarf stars have been discovered with ages far exceeding the typical protoplanetary disc lifetime. These `Peter Pan discs' can be explained as primordial discs that evolve in a low-radiation environment. The persistently low masses of the host stars raise the question whether primordial discs can survive up to these ages around stars of higher mass. In this work we explore the way in which different mass loss processes in protoplanetary discs limit their maximum lifetimes, and how this depends on host star mass. We find that stars with masses $\lesssim$ 0.6 M$_\odot$ can retain primordial discs for $\sim$50 Myr. At stellar masses $\gtrsim$ 0.8 M$_\odot$, the maximum disc lifetime decreases strongly to below 50 Myr due to relatively more efficient accretion and photoevaporation by the host star. Lifetimes up to 15 Myr are still possible for all host star masses up to $\sim$2 M$_\odot$. For host star masses between 0.6 and 0.8 M$_\odot$, accretion ceases and an inner gap forms before 50 Myr in our models. Observations suggest that such a configuration is rapidly dispersed. We conclude that Peter Pan discs can only occur around M dwarf stars.

Biomasse e loro quantificazione economica per un efficiente uso dell'energia

Subjects: AGR/01 Economia ed estimo rurale

description: Biomasses and their possible use as energy resource are of great interest today, and the general problem of energy resources as well. In the present study the key questions of the convenience, from both energy and economy  standpoints, have been addressed without any bias: the problem has been handled starting from “philosophical” bases disregarding any pre-settled ideology or political trend, but simply using mathematical approaches as logical tools for defining balances in a right way. In this context quantitative indexes such as LCA and EROEI have been widely used, together with multicriteria methods (such as ELECTRE) as decision supporting tools. This approach permits to remove mythologies, such as the unrealistic concept of clean energy, or the strange idea of biomasses as a magic to solve every thing in the field of the energy. As a consequence the present study aims to find any relevant aspect potentially useful for the society, looking at any possible source of energy without prejudices but without unrealistic expectations too. For what concerns biomasses, we studied in great details four very different cases of study, in order to have a scenario as various as much we can. A relevant result is the need to use biomasses together with other more efficient sources, especially recovering by-products from silviculture activities: but attention should be paid to the transportation and environmental costs. Another relevant result is the very difficult possibility of reliable evaluation of dedicated cultures as sources for “biomasses for energy”: the problem has to be carefully evaluated case-by-case, because what seems useful in a context, becomes totally disruptive in another one. In any case the concept itself of convenience is not well defined at a level of macrosystem: it seems more appropriate to limit this very concept at a level of microsystem, considering that what sounds fine in a limited well defined microsystem may cause great damage in another slightly different, or even very similar, microsystem. This approach seems the right way to solve the controversy about the concept of convenience.

description: With the development of the fourth industrial revolution technology, the type and scope of use of drones are rapidly increasing. As interest in drones increases, research on related security vulnerabilities is actively being conducted, and discussions on security measures have also been developed to prevent them. Military has established and applied various security measures for this, and in particular, drones equipped with KCMVP-certified cryptographic modules are required to be introduced as a way to protect data on the drone's wireless channels. However, despite being equipped with such a certified cryptographic module, the drone's operating environment and structural properties have the potential to expose it to several security vulnerabilities. In this paper, we present a theoretical model for these security vulnerabilities and measures to complement them.

Reconstruction and analysis of the NF-kB pathway interactome: a systems biology approach

description: Background. One of the phenomena observed in human aging is the progressive increase of a systemic inflammatory state, a condition referred to as “inflammaging”, negatively correlated with longevity. A prominent mediator of inflammation is the transcription factor NF-kB, that acts as key transcriptional regulator of many genes coding for pro-inflammatory cytokines. Many different signaling pathways activated by very diverse stimuli converge on NF-kB, resulting in a regulatory network characterized by high complexity. NF-kB signaling has been proposed to be responsible of inflammaging. Scope of this analysis is to provide a wider, systemic picture of such intricate signaling and interaction network: the NF-kB pathway interactome.

Methods. The study has been carried out following a workflow for gathering information from literature as well as from several pathway and protein interactions databases, and for integrating and analyzing existing data and the relative reconstructed representations by using the available computational tools. Strong manual intervention has been necessarily used to integrate data from multiple sources into mathematically analyzable networks. The reconstruction of the NF-kB interactome pursued with this approach provides a starting point for a general view of the architecture and for a deeper analysis and understanding of this complex regulatory system.

Results. A “core” and a “wider” NF-kB pathway interactome, consisting of 140 and 3146 proteins respectively, were reconstructed and analyzed through a mathematical, graph-theoretical approach. Among other interesting features, the topological characterization of the interactomes shows that a relevant number of interacting proteins are in turn products of genes that are controlled and regulated in their expression exactly by NF-kB transcription factors. These “feedback loops”, not always well-known, deserve deeper investigation since they may have a role in tuning the response and the output consequent to NF-kB pathway initiation, in regulating the intensity of the response, or its homeostasis and balance in order to make the functioning of such critical system more robust and reliable. This integrated view allows to shed light on the functional structure and on some of the crucial nodes of thet NF-kB transcription factors interactome.

Conclusion. Framing structure and dynamics of the NF-kB interactome into a wider, systemic picture would be a significant step toward a better understanding of how NF-kB globally regulates diverse gene programs and phenotypes. This study represents a step towards a more complete and integrated view of the NF-kB signaling system.

Gauge fields in (A)dS within the unfolded approach: algebraic aspects

description: It has recently been shown that generalized connections of the (A)dS space symmetry algebra provide an effective geometric and algebraic framework for all types of gauge fields in (A)dS, both for massless and partially-massless. The equations of motion are equipped with a nilpotent operator called $σ_-$ whose cohomology groups correspond to the dynamically relevant quantities like differential gauge parameters, dynamical fields, gauge invariant field equations, Bianchi identities etc. In the paper the $σ_-$-cohomology is computed for all gauge theories of this type and the field-theoretical interpretation is discussed. In the simplest cases the $σ_-$-cohomology is equivalent to the ordinary Lie algebra cohomology.

description: We report the numerical realization and demonstration of robustness of certain 2-component structures in Bose-Einstein Condensates in 2 and 3 spatial dimensions with non-trivial topological charge in one of the components. In particular, we identify a stable symbiotic state in which a higher-dimensional bright soliton exists even in a homogeneous setting with defocusing interactions, as a result of the effective potential created by a stable vortex in the other component. The resulting vortex-bright solitary waves, which naturally generalize the recently experimentally observed dark-bright solitons, are examined both in the homogeneous medium and in the presence of parabolic and periodic external confinement and are found to be very robust.

description: FORM er en forkortelse for "FOrretningsReferenceModel". Som udgangspunkt er FORM et katalog på overordnet niveau over samtlige opgaver, der udføres i den offentlige sektor: Statens, regionerne og kommunerne. Det betyder, at FORM fx er velegnet til brug i fx analyser og som et overblik på tværs af hele den offentlige sektor.
Ved at de enkelte myndigheder refererer deres egen lokale systematik op mod et fællesoffentligt FORM-nummer, etableres et "fælles sprog/referencepunkt", der giver mulighed for sammenhæng samt mulighed for udveksling af data/oplysninger i en fælles referenceramme.

Liquid film dynamics with immobile contact line during meniscus oscillation

description: This paper presents a theoretical analysis of the liquid film dynamics during the oscillation of a meniscus between a liquid and its vapour in a cylindrical capillary. By using the theory of Taylor bubbles, the dynamic profile of the deposited liquid film is calculated within the lubrication approximation accounting for the finiteness of the film length, i.e. for the presence of the contact line. The latter is assumed to be pinned on a surface defect and thus immobile; the contact angle is allowed to vary. The fluid flow effect on the curvature in the central meniscus part is neglected. This curvature varies in time because of the film variation and is determined as a part of the solution. The film dynamics depends on the initial contact angle, which is the maximal contact angle attained during oscillation. The average film thickness is studied as a function of system parameters. The numerical results are compared to existing experimental data and to the results of the quasi-steady approximation. Finally, the problem of an oscillating meniscus is considered accounting for the superheating of the capillary wall with respect to the saturation temperature, which causes evaporation. When the superheating exceeds a quite low threshold, oscillations with a pinned contact line are impossible and the contact line recession caused by evaporation needs to be accounted for.

description: Achieving metrological precision of quantum anomalous Hall resistance quantization at zero magnetic field so far remains limited to temperatures of the order of 20 mK, while the Curie temperature in the involved material is as high as 20 K. The reason for this discrepancy remains one of the biggest open questions surrounding the effect, and is the focus of this article. Here we show, through a careful analysis of the non-local voltages on a multi-terminal Corbino geometry, that the chiral edge channels continue to exist without applied magnetic field up to the Curie temperature of bulk ferromagnetism of the magnetic topological insulator, and that thermally activated bulk conductance is responsible for this quantization breakdown. Our results offer important insights on the nature of the topological protection of these edge channels, provide an encouraging sign for potential applications, and establish the multi-terminal Corbino geometry as a powerful tool for the study of edge channel transport in topological materials.
Reducing the detection of genuine entanglement of n qubits to two qubits

Publisher: name: arXiv

description: We propose a criterion for the detection of genuine entanglement of pure multiqubit states. To this aim, we define an operator called the losing one qubit operator, which is different from the reduced density operator. The states obtained from a multiqubit state by applying the losing one qubit operator are referred to as its projected states. We show that all of the projected states of a pure product n-qubit state are pure product states provided that it cannot be written as a product of a single qubit state and a genuinely entangled (n-1)-qubit state. We also show that a pure n-qubit state is genuinely entangled provided that the state has at least two genuinely entangled (n-1)-qubit projected states. By repeating the losing process, we reduce the detection of entanglement of pure n-qubit states to the one of pure two-qubit states. Also we write a LISP program for the reduction process.

Smoothing nodal Calabi-Yau n-folds

description: Let X be an n-dimensional Calabi-Yau with ordinary double points, where n is odd. Friedman showed that for n=3 the existence of a smoothing of X implies a specific type of relation between homology classes on a resolution of X. (The converse is also true, due to work of Friedman, Kawamata and Tian.) We sketch a more topological proof of this result, and then extend it to higher dimensions. For n>3 the "Yukawa product" on the middle dimensional (co)homology plays an unexpected role. We also discuss a converse, proving it for nodal Calabi-Yau hypersurfaces in projective space.

ODIP: Towards Automatic Adaptation for Object Detection by Interactive Perception

description: Object detection plays a deep role in visual systems by identifying instances for downstream algorithms. In industrial scenarios, however, a slight change in manufacturing systems would lead to costly data re-collection and human annotation processes to re-train models. Existing solutions such as semi-supervised and few-shot methods either rely on numerous human annotations or suffer low performance. In this work, we explore a novel object detector based on interactive perception (ODIP), which can be adapted to novel domains in an automated manner. By interacting with a grasping system, ODIP accumulates visual observations of novel objects, learning to identify previously unseen instances without human-annotated data. Extensive experiments show ODIP outperforms both the generic object detector and state-of-the-art few-shot object detector fine-tuned in traditional manners. A demo video is provided to further illustrate the idea.
