Probing dense matter in neutron stars with axial w-modes

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We study the problem of extracting information about composition and equation of state of dense matter in neutron star interior using axial w-modes. We determine complex frequencies of axial w-modes for a set of equations of state involving hyperons as well as Bose-Einstein condensates of antikaons adopting the continued fraction method. Hyperons and antikaon condensates result in softer equations of state leading to higher frequencies of first axial w-modes than that of nuclear matter case, whereas the opposite happens in case of damping times. The presence of condensates may lead to the appearance of a new stable branch of superdense stars beyond the neutron star branch called the third family. The existence of same mass compact stars in both branches are known as neutron star twins. Further investigation of twins reveal that first axial w-mode frequencies of superdense stars in the third family are higher than those of the corresponding twins in the neutron star branch.

description: We review a recently discovered continuum limit for the one-matrix model which describes "causal" two-dimensional quantum gravity. The behaviour of the quantum geometry in this limit is different from the quantum geometry of Euclidean two-dimensional quantum gravity defined by taking the "standard" continuum limit of the one-matrix model. Geodesic distance and time scale with canonical dimensions in this new limit, contrary to the situation in Euclidean two-dimensional quantum gravity. Remarkably, whenever we compare, the known results of (generalized) causal dynamical triangulations are reproduced exactly by the one-matrix model. We complement previous results by giving a geometrical interpretation of the new model in terms of a generalization of the loop equation of Euclidean dynamical triangulations. In addition, we discuss the time evolution of the quantum geometry.

description: Theory of non-stationary coherent effects is developed for superconductor-normal-superconductor (SNS) structures with relatively strong normal scattering on S/N interfaces (interface resistance is large compared to intrinsic resistance of N metal). Analitical expressions are found for the time-dependent anomalous Green functions induced in the N region under the fixed-voltage-bias. The amplitude of the current oscillations is determined in non-equilibrium conditions. Non-stationary correction to the distribution function is calculated in high-temperature limit and found to be slowly decreasing with the temperature, leading to the dominance of the second-harmonic term in the Josepshon current at high temperatures and low voltage.

Binary planetary nebulae nuclei towards the Galactic bulge. II. A penchant for bipolarity and low-ionisation structures

description: Considerable effort has been applied towards understanding the precise shaping mechanisms responsible for the diverse range of morphologies exhibited by planetary nebulae (PNe). A binary companion is increasingly gaining support as a dominant shaping mechanism, however morphological studies of the few PNe that we know for certain were shaped by binary evolution are scarce or biased. Newly discovered binary central stars (CSPN) from the OGLE-III photometric variability survey have significantly increased the sample of post common-envelope (CE) nebulae available for morphological analysis. We present Gemini South narrow-band images for most of the new sample to complement existing data in a qualitative morphological study of 30 post-CE nebulae. Nearly 30% of nebulae have canonical bipolar morphologies, however this rises to 60% once inclination effects are incorporated with the aid of geometric models. This is the strongest observational evidence yet linking CE evolution to bipolar morphologies. A higher than average proportion of the sample shows low-ionisation knots, filaments or jets suggestive of a binary origin. These features are also common around emission-line nuclei which may be explained by speculative binary formation scenarios for H-deficient CSPN.

description: We consider Feller mean-reverting square-root diffusion, which has been applied to model a wide variety of processes with linearly state-dependent diffusion, such as stochastic volatility and interest rates in finance, and neuronal and populations dynamics in natural sciences. We focus on the statistical mixing (or superstatistical) process in which the parameter related to the mean value can fluctuate - a plausible mechanism for the emergence of heavy-tailed distributions. We obtain analytical results for the associated probability density function (both stationary and time dependent), its correlation structure and aggregation properties. Our results are applied to explain the statistics of stock traded volume at different aggregation scales.

description: Classic psychedelics and MDMA have a colorful history of recreational use, and both have recently been re-evaluated as tools for the treatment of psychiatric disorders. Several studies have been carried out to assess potential long-term effects of a regular use on cognition, delivering distinct results for psychedelics and MDMA. However, to date knowledge is scarce on cognitive performance during acute effects of those substances. In this systematic review and meta-analysis, we investigate how cognitive functioning is affected by psychedelics and MDMA during the acute drug effects and the sub-acute (“afterglow”) window. Our quantitative analyses suggest that acute cognitive performance is differentially affected by psychedelics when compared to MDMA: psychedelics impair attention and executive function, whereas MDMA primarily affects memory, leaving executive functions and attention unaffected. Our qualitative analyses reveal that executive functioning and creativity may be increased during a window of at least 24 h after the acute effects of psychedelics have subsided, whereas no such results have been observed for MDMA. Our findings may contribute to inform recommendations on harm reduction for recreational settings and to help fostering differential approaches for the use of psychedelics and MDMA within a therapeutic framework.

Geochemical dispersion in bedrock and glacial overburden around a copper property in south central British Columbia
Creators: name: Hoffman, Stanley J.
Publisher: name: University of British Columbia
Year: 2011

description: The Rayfield River copper property, 14 miles east of 70 Mile House in south central British Columbia, is underlain by a zoned syenite intrusion of late Triassic or early Jurassic age. The batholith was introduced into Mesozoic volcanics of the Nicola Group and has since been partially buried by Tertiary Basalt flows. The syenite grades from several hybrid phases at the country rock contact, through hornblende syenite, to leucocratic syenite and finally, to several centrally disposed pegmatitic bodies. Chalcopyrite and bornite, the major sulphides present, occur as inclusions within hornblende, along feldspar veinlets and along fractures in a concentric zone surrounding the leucrocratic syenite. On the property, the Rayfield River dissects to 400 feet, a gently rolling plateau. Glacial deposits are rare along the valley but commonly approach 50 feet in thickness on the plateau. Soil, lake sediment and water samples collected from these young and relatively unweathered surficial deposits are alkaline. Talus soils along the valley, however, are slightly more acidic, due to oxidation of primary sulphide minerals. The value of geochemical patterns in locating bedrock mineralization may be gauged by the success attained where sources of copper in bedrock are known. Three copper rich areas have been found. The most striking bedrock anomaly, near the center of the property, is outlined by copper-rich syenite float, stream sediment, lake water and sediment and talus soils. The second, along the northern half of the river valley, was found by stream sediment and talus surveys. The third bedrock anomaly, on the southeastern fraction of the property, is surrounded by float blocks relatively high in copper. Copper enrichment within glacial overburden is usually detectable over twice the area underlain by bedrock mineralization. Most secondary anomalies overly batholithic rocks, except in the south where rounded syenite float blocks, mineralogically and structurally similar to the most striking bedrock anomaly, were transported by a glacial Bonaparte River to where they now overly Nicola Volcanics. On a regional survey, boulder tracing and lake sediment or lake water sampling are most likely to indicate the presence of a mineralized intrusive. Detailed sampling reveals anomalous stream sediments of the Rayfield River and copper-rich talus along the valley sides of the northern half of the property. Detailed soil sampling is not suitable for outlining copper mineralization, as alkaline soil and thick overburden restrict movement of copper ions. Erratic high copper values are usually related to mineralized float or bedrock. Analysis of second year growth of Douglas fir or lodgepole pine apparently does not detect mineralization in bedrock.

description: Based on previous studies deriving the chiral Lagrangian for pseudo scalar mesons from the first principle of QCD in the path integral formalism, we derive the electroweak chiral Lagrangian and dynamically compute all its coefficients from the one family technicolor model. The numerical results of the $p^4$ order coefficients obtained in this paper are proportional to the technicolor number $N_{\rm TC}$ and the technifermion number $N_{\rm TF}$, which agrees with the arguments in previous works, and which confirms the reliability of this dynamical computation.

description: Using a first-principles parameterized lattice-gas Hamiltonian we study the adsorbate ordering behavior at atomic steps of a Pd(100) surface exposed to an oxygen environment. We identify a wide range of gas-phase conditions comprising near atmospheric pressures and elevated temperatures around 900 K, in which the step is decorated by a characteristic O zigzag arrangement. For catalytic processes like the high-temperature combustion of methane that operate under these conditions our approach thus provides first insight into the structure and composition at a prominent defect on the working surface.

The initial conditions and parton evolution based on perturbative QCD in the chemical non-equilibrated medium and Bjorken expanding medium at RHIC are determined. The parton evolution affect the jet energy loss evidently. This will increase the energy and propagating distance dependence of the parton energy loss and will affect the shape of suppression of moderately high P_{T} hadron spectra.

Abstract: 

Humanity has a mix of overlapping goals that relate to science (and more broadly, wissenschaft). We seek new knowledge for its own purpose as well as for its potential solution to both detailed and general problems, situations, and crises. And we want to be able to verify (or disprove) such knowledge (reproducibility), then build on it (reuse), as simply and as cost-effectively as possible. This knowledge can be captured in text, images, data, software, etc. In this talk, I will focus on knowledge captured in research software, which can be both read, executed, and extended. However, software, unlike data, requires ongoing human activity to fix bugs and to adapt to frequent changes in the software and hardware environment on which it depends, as well as changing user needs. This required human activity leads to different models of software sustainability, including a mix of open source communities, industrial or government support, and commercialization, some of which are also tied to different distribution mechanisms, such as source code, executables, containers, and services.

This leads to a number of overlapping challenges and corresponding efforts, including making research software FAIR (findable, accessible, interoperable, and reusable), publishable, and citable, as well as considering how to support the human effort needed to maintain and sustain the software, including incentives and career paths.  This talk will highlight some recent activities in these areas, including FAIR for research software principles, software citation, the Journal of Open Source Software, and software career paths.

description: The design, construction, and commissioning of the ALICE Time-Projection Chamber (TPC) is described. It is the main device for pattern recognition, tracking, and identification of charged particles in the ALICE experiment at the CERN LHC. The TPC is cylindrical in shape with a volume close to 90 m^3 and is operated in a 0.5 T solenoidal magnetic field parallel to its axis. In this paper we describe in detail the design considerations for this detector for operation in the extreme multiplicity environment of central Pb--Pb collisions at LHC energy. The implementation of the resulting requirements into hardware (field cage, read-out chambers, electronics), infrastructure (gas and cooling system, laser-calibration system), and software led to many technical innovations which are described along with a presentation of all the major components of the detector, as currently realized. We also report on the performance achieved after completion of the first round of stand-alone calibration runs and demonstrate results close to those specified in the TPC Technical Design Report.

description: Natural attenuation is a major ecosystem function allowing to abate soil organic contaminants such as polycyclic aromatic hydrocarbons (PAHs). Biodegradation of PAHs is classically considered as the major driver of natural attenuation, yet the role of abiotic transformation, including photodegradation, chemical oxidation, formation of non-extractable residues, and polymerization, has been overlooked due to the lack of investigations until recently. This paper reviews PAHs dissipation in soils by abiotic processes such as photodegradation and oxidation catalyzed by inorganic minerals and organic matters. The role of soil components on degradation rates, pathways, and mechanisms are discussed. The products of PAHs abiotic transformation and their potential risks are also described. Abiotic transformations are mainly controlled by interactions between PAHs and clay minerals, metal oxides/hydroxides, and soil organic matter. PAH photodegradation proceeds by both direct and indirect photolysis processes, which are enhanced in the presence of natural photosensitizers, for example, organic matter, and photocatalysts, for example, metal oxides/hydroxides. PAHs can also be chemically/catalytically oxidized by metal oxides/hydroxides, for example, MnO2, FexOy, and clay minerals without light irradiation. Overall, PAHs transformation depends on their electron-donating properties, mineral electron-accepting properties, pH, temperature, moisture, and oxygen content. Following the elucidation of the transformative mechanism, knowledge to understand the impact of abiotic transformation on biodegradation are delineated. Future investigations are needed to advance the correlation of laboratory generated rates to the field applications, and the potential applications of natural attenuation based on abiotic processes are proposed.

description: We present simulations within the framework of scalar-tensor theories, in the Newtonian limit, to investigate the influence of massive scalar fields on the dynamics of the collision of two equal spherical clouds. We employ a SPH code modified to include the scalar field to simulate two initially non-rotating protogalaxies that approach each other, and as a result of the tidal interaction, intrinsic angular momentum is generated. We have obtained sufficient large values of J/M to suggest that intrinsic angular momentum can be the result of tidal interactions.

description: We study the effect of small decoherence in continuous-time quantum walks on long-range interacting cycles, which are constructed by connecting all the two nodes of distance m on the cycle graph. In our investigation, each node is continuously monitored by an individual point contact, which induces the decoherence process. We obtain the analytical probability distribution and the mixing time upper bound. Our results show that, for small rates of decoherence, themixing time upper bound is independent of distance parameter m and is proportional to inverse of decoherence rate.

description: The starting point of this thesis is the description of the general legislative framework, at an international, EU and national level, as well as the applicable provisions for the protection of data in scientific and specifically in clinical research. Moreover the categories of personal data that are processed in such research, what constitutes processing and who are the parties involved in it are analyzed. In addition, what constitutes "research" is described, what is included in such generally, while clinical trials are also presented in particular. Emphasis is placed on the analysis of the legal basis for processing personal data in the context of both primary and secondary research.In the context of the EU and national legislation, the principles governing the processing and the rights of the data subjects, in the light of the processing of the data in research, are listed as well. Finally, the obligations of the data controller and the data processor are also outlined, as well as the safeguards provided by the current legislative framework for the protection of personal data.
Minor elements in pyrites from the smithers map area, b.c. and exploration applications of minor element studies
Creators: name: Price, Barry James
Publisher: name: University of British Columbia
Year: 2011

description: This study was undertaken to determine minor element geochemistry of pyrite and the applicability of pyrite minor-element research to exploration for mineral deposits. Previous studies show that Co, Ni, and Cu are the most prevalent cations substituting for Fe in the pyrite lattice; significant amounts of As and Se can substitute for S. Other elements substitute less commonly and in smaller amounts within the lattice, in interstitial sites, or within discrete mechanically-admixed phases. Mode of substitution is determined most effectively with the electron microprobe. Cation substitution for Fe²⁺ is favored by transition elements with non-bonding "d" electrons .in low-spin configurations, an octahedral covalent radius similar to that of Fe (1.23 [symbol omitted] and high electronegativity. Anion substitution for S is favored by chalcogeri and pnigogen elements with a tetrahedral coordination radius close to 1.04 [symbol omitted] and high electronegativity. Statistical tests performed on several hundred pyrite analyses compiled from the literature and stored on computer cards support: (l) log-normal frequency distributions of minor elements in hydrothermal pyrite; (2) redistribution of minor elements in pyrite by metamorphism; (3) statistical differentiation of hydro-thermal, volcanic-exhalative, and syngenetic pyrites on the basis of Co and Ni concentrations and ratios; (4) relationship of minor element "spectra" and concentrations in disseminated pyrite to those in adjacent rocks; and (5) relationship of minor-element concentrations in hydrothermal pyrites to major ore-forming elements present. Forty pyrite samples from several distinct types of mineral deposits in the Smithers area, B.C. were analyzed for Co, Ni, Mn, Cu, Pb, and Zn using atomic-absorption spectrophotometry. Co concentrations are highest in pyrites from volcanic rocks, massive sulphide deposits and a breccia pipe. Ni and Mn concentrations are uniformly low. High contents of Cu, Fb, and Zn are caused by inclusions of common sulphides. Calculation of correlation coefficients for minor elements revealed that contamination does not significantly affect Co or Ni concentrations. Minor element data from the Smithers pyrites provides evidence for genetic relationships between several different mineral deposits, the presence of "metallogenetic" sub-provinces, and minor-element zonation in mineral deposits. Research into minor-element geochemistry of pyrite can be useful in exploration for mineral deposits; most effective use is during secondary stages of exploration. Most useful elements for exploration applications are Co, Ni, Cu, Au, Ag, Hg, Tl, Sn, As, and Se.
The Global Impact of the "War on Terror": The Case of the People's Republic of China and Uyghur Muslims in the Xinjiang Uyghur Autonomous Region

description: In this thesis, I examine the global implications of the "War on Terror" by exploring how China exploits the discourses of the "War on Terror" to justify the internment of Uyghur Muslims. In the Xinjiang Uyghur Autonomous Region, the Chinese government is responsible for human rights abuses, violations, and genocide of Uyghur Muslims and other Turkic minority groups. In 2018, it was reported that approximately more than one million Uyghur Muslims and other Muslim minorities in China have disappeared and are subject to arbitrary detention, surveillance, forced labour, forced sterilization, and regulations which restrict religious and cultural expression in supposed "counter-extremism centers" allegedly committed to political indoctrination fighting terrorism (Human Rights Watch, 2021; United Nations Human Rights, 2018). This study explores the processes and practices used to deny the internment of the Uyghur Muslim population. I achieve this through my research question, which aims to explore: How the Chinese government manufactures and justifies its own "War on Terror" by suppressing Uyghur Muslims and simultaneously denying the use of internment camps? I analyzed pro-government national China Daily English newspaper articles from 2001-2020 using qualitative content analysis to answer this research question. As a result, my main argument is that the Chinese government has manufactured and exacerbated a domestic "terrorism" problem by exploiting the discourses of the "War on Terror" to justify its internment of Uyghur Muslims. Simultaneously, the Chinese government has produced a deflection campaign committed to diverting criticisms and denying the use of internment camps under the guise of the "War on Terror." I conclude this thesis by presenting the need for additional research to explore how other countries in the East might also suppress different racialized groups in the context of the "War on Terror."
Sudden Death of Entanglement

description: A new development in the dynamical behavior of elementary quantum systems is the surprising discovery that correlation between two quantum units of information called qubits can be degraded by environmental noise in a way not seen previously in studies of dissipation. This new route for dissipation attacks quantum entanglement, the essential resource for quantum information as well as the central feature in the Einstein-Podolsky-Rosen so-called paradox and in discussions of the fate of Schröinger's cat. The effect has been labeled ESD, which stands for early-stage disentanglement or, more frequently, entanglement sudden death. We review recent progress in studies focused on this phenomenon.

description: A description of exclusive charged pion electroproduction $(e,e'π^{\pm})$ off nucleons at high energies is proposed. The model combines a Regge pole approach with residual effect of nucleon resonances. The exchanges of $π$(140), vector $ρ(770)$ and axial-vector $a_1(1260)$ and $b_1(1235)$ Regge trajectories are considered. The contribution of nucleon resonances is described using a dual connection between the exclusive hadronic form factors and inclusive deep inelastic structure functions. The model describes the measured longitudinal, transverse and interference cross sections at JLAB and DESY. The scaling behavior of the cross sections is in agreement with JLAB and deeply virtual HERMES data. The results for a polarized beam-spin azimuthal asymmetry in $(\vec{e},e'π^{\pm})$ are presented. Model predictions for JLAB at 12 GeV are given.

Motion of spiral waves in the Complex Ginzburg-Landau equation

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: Solutions of the general cubic complex Ginzburg-Landau equation comprising multiple spiral waves are considered. For parameters close to the vortex limit, and for a system of spiral waves with well-separated centres, laws of motion of the centres are found which vary depending on the order of magnitude of the separation of the centres. In particular, the direction of the interaction changes from along the line of centres to perpendicular to the line of centres as the separation increases, with the strength of the interaction algebraic at small separations and exponentially small at large separations. The corresponding asymptotic wavenumber and frequency are determined. These depend on the positions of the centres of the spirals, and so evolve slowly as the spirals move.
