Hadrons As Kerr-Newman Black Holes
Creators: name: Oldershaw, R. L.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The scale invariance of the source-free Einstein field equations suggests that one might be able to model hadrons as "strong gravity" black holes, if one uses an appropriate rescaling of units or a revised gravitational coupling factor. The inner consistency of this hypothesis is tested by retrodicting a close approximation to the mass of the proton from an equation that relates the angular momentum and mass of a Kerr black hole. More accurate mass and radius values for the proton are then retrodicted using the geometrodynamics form of the full Kerr-Newman solution of the Einstein-Maxwell equations. The radius of an alpha particle is calculated as an additional retrodictive test. In a third retrodictive test of the "strong gravity" hypothesis, the subatomic particle mass spectrum in the 100 MeV to 7,000 MeV range is retrodicted to a first approximation using the Kerr solution of General Relativity. The particle masses appear to form a restricted set of quantized values of the Kerr solution: n^1/2 M, where values of n are a set of discrete integers and M is the revised Planck mass. The accuracy of the 27 retrodicted masses averages 98.4%. Finally, the new atomic scale gravitational coupling constant suggests a radical revision of the assumptions governing the Planck scale, and leads to a natural explanation for the fine structure constant.

Delocalization from Anomaly Inflow and Intersecting Brane Dynamics
Creators: name: Grisa, Luca
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study intersecting D-brane models, that describe at low energies a two dimensional chiral fermion theory localized at the intersection. The fermions are coupled to gauge fields in the bulk. The resulting low energy theory is equivalent to the Gross-Neveu model with dynamical chiral symmetry breaking. No Nambu-Goldstone boson associated with spontaneously broken symmetries appears in two dimensional field theories. In the present work we discuss solvable models with the same basic dynamics of the dual Gross-Neveu model. The disappearance of the Nambu-Goldstone boson is obtained from D-brane dynamics. The mechanism relies on the non-trivial dynamics of a gauge field due to anomaly inflow.

The isolation and characterization of fetal haematopoietic cells from maternal peripheral blood
Creators: name: Little, Marie-Térèse
Publisher: name: University of British Columbia
Year: 2009

description: Fetal cells that circulate in maternal peripheral blood during pregnancy offer a potential source of nucleated fetal material for low-risk non-invasive prenatal diagnosis. Despite some promising results and numerous investigations in this field, many of the basic questions regarding the circulation of fetal cells in the maternal blood remain unanswered. Specifically, more information on the frequency and type of fetal cells that circulate during pregnancy needs to be established, the possibility of clonally expanding fetal cells needs to be explored, and techniques that will facilitate the identification and isolation of fetal cells need to be developed before this technique can be implemented for routine prenatal screening. Progenitor cells from normal human adult bone marrow and fetal liver were sorted using multidimensional flow cytometry on the basis of expression of CD34, CD71, CD45 and Glycophorin-A and cultured in the presence of various haematopoietic cytokines. Subtle differences in phenotype and function between fetal and adult cells and a reproducible enrichment strategy were identified that could potentially be applied to identify fetal cells from maternal peripheral blood. Fluorescence activated cell sorting (FACS) was then used to target two populations of fetal cells: nucleated erythroid cells (NECs; CD71/Glycophorin-A⁺ CD45[sup lo-int] CD34⁻) and haematopoietic progenitor cells (CD34⁺ cells; CD34⁺⁺ CD71/Glycophorin-A- CD45[sup int]). Fetal cells were detected by fluorescence in situ hybridization using directly conjugated chromosome X and Y probes in 65% of the maternal peripheral bloods (fetal karyotype 46,XY). The frequency of fetal cells isolated from the NEC and CD34⁺ fractions was, respectively, 0-14 and 0-7 cells per 2x10⁷ previously frozen maternal cells (-20 mL of blood). In non-frozen samples, the yield and recovery of fetal cells was moderately improved. Culturing the CD34⁺ sorted fractions in serum-free media with cytokines improved the quality of the FISH preparations and resulted in a slight expansion in detectable fetal cells. The frequency of fetal cells isolated from cultured CD34⁺ fractions was 0-35 and 0-93 cells per 2x10⁷ previously frozen and non-frozen maternal peripheral blood cells, respectively. These results document the isolation, characterization, and enumeration of fetal cells from the maternal periphery that appear to be present in most, but not all samples analyzed.

description: Towards the end of brane inflation, the brane pair annihilation produces massive closed strings. The transfer of this energy to Standard Model (SM) open string modes depends on where the SM branes and the brane annihilation are located: in the bulk, in the same throat or in different throats. We find that, in all cases as long as the brane annihilation and the SM branes are not both in the bulk, the transfer of energy to start the hot big bang epoch can be efficient enough to be compatible with big bang nucleosynthesis. The suppression of the abundance of the graviton and its Kaluza-Klein (KK) thermal relics follows from the warped geometry in flux compactification. This works out even in the scenarios where a long period of tunneling is expected. In the multi-throat scenario, we find a dynamical mechnism of selecting a long throat as the SM throat. We establish three new dark matter candidates: KK modes with specific angular momentum in the SM throat, those in the brane annihilation throat, and different matters generated by KK modes tunneled to other throats. Since the latter two couple to the visible matter sector only through graviton mediation, they behave as hidden dark matter. Hidden dark matter has novel implications on the dark matter coincidence problem and the high energy cosmic rays.

Year: 2024

description: In this paper, we report the performance of a high-capacity, fast-charging, and reliable supercapacitor consisting of manganese dioxide (MnO2) on carbon nanotube (CNT) electrodes fabricated using a simple and efficient electrodeposition method. The MnO2@CNT composite electrodes formed on a flexible carbon fabric demonstrated excellent electrochemical energy storage capabilities as confirmed by cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) experiments. The MnO2 loading significantly affected the electrode's capacity, with the highest specific capacitance of 219 F g-1 achieved at low mass loading (3.37 mg cm-2 ) and the highest areal capacitance of 1.5 F cm-2 for high mass loading (15.6 mg cm-2 ). The electrode also showed outstanding stability, retaining 87% of its initial capacity after 2000 cycles. Electrochemical impedance spectroscopy (EIS) measurement and corresponding analysis of the data indicated fast charge transfer kinetics and facile ion diffusion into the MnO2 electrode, which is attributed to the nanoflower-like structure of MnO2 formed on porous carbon nanotubes, leading to excellent rate performance.
A Balmer-line Broad Absorption Line Quasar
Creators: name: Hall, Patrick B.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: I report the discovery of blueshifted broad absorption line (BAL) troughs in at least six transitions of the Balmer series of hydrogen (Hbeta to H9) and in CaII, MgII and excited FeII in the quasar SDSS J125942.80+121312.6. This is only the fourth active galactic nucleus known to exhibit Balmer absorption, all four in conjunction with low-ionization BAL systems containing excited Fe II. The substantial population in the n=2 shell of H I in this quasar's absorber likely arises from Ly-alpha trapping. In an absorber sufficiently optically thick to show Balmer absorption, soft X-rays from the quasar penetrate to large τ_Lyαand ionize H I. Recombination then creates Ly-alpha photons that increase the n=2 population by a factor τ_Lyαsince they require about τ_Lyαscatterings to diffuse out of the absorber. Observing Ly-alpha trapping in a quasar absorber requires a large but Compton-thin column of gas along our line of sight which includes substantial H I but not too much dust. Presumably the rarity of Balmer-line BAL troughs reflects the rarity of such conditions in quasar absorbers.

description: We present the formation and eruption of a sigmoidal filament driven by rotating network magnetic fields (RNFs) near the center of the solar disk, which was observed by the one-meter aperture New Vacuum Solar Telescope (NVST) at Fuxian Solar Observatory (FSO) on 2018 July 12. Counterclockwise RNFs twist two small-scale filaments at their northeastern foot-point region, giving a rotation of nearly 200 degree within about 140 minutes. The motion of the RNF has a tendency to accelerate at first and then decelerate obviously, as the average rotation speed increased from 10 to 150 ,and then slowed down to 50 . Coalescence then occurs between filaments F1 and F2. Meanwhile the fine structures in the southwestern region of the filament was involved in another interaction of coalescence. The subsequent EUV brightening due to plasma heating is observed in the two interaction regions. These interacting structures, including F1, F2 and the fine structures in the southwestern region, eventually evolve into a larger-scale sigmoidal filament twisted in the same direction as the RNFs gave. The twist of the sigmoidal filament has exceeded 4π and the filament erupted finally. The motion of the sigmoidal filament keeps uniform until a nearby jet collides, causing the filament to erupt faster. These results provide evidence that RNF plays an important role in the formation and eruption of the sigmoidal filament. The phenomena also suggests that the kink instability is the trigger mechanism for the filament eruption.

The entropy of a large block of neighboring spins approaches a constant as the size of the block increases. We prove rigorously expression for limiting entropy which was published before. We observe that the entropy reaches minimum at product states but increases boundlessly at phase transitions.

Perturbative method to estimate meson masses in the framework of Bethe-Salpeter equation beyond its dominant interaction
Creators: name: Xu, Shu-Sheng

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a novel method to calculate the meson mass in the framework of Dyson-Schwinger equation and Bethe-Salpeter equation, once their dominant interactions are identified. The method is based on the perturbation theory of matrix, which is widely used in quantum mechanics. Taking interactions other than the dominant ones as perturbations, we derive the first order correction of quark propagator. Implementing the perturbation on BSE, the mass correction at first order is then given. We exemplify this method with the well known Rainbow-Ladder (RL) truncation, and go beyond the RL using a simple model, i.e., the Munczek-Nemirovsky~(MN) model, by studying the pion and $ρ$ mesons mass shift. The results are all in good agreement with those obtained by fully solving the BSE beyond RL. Our perturbative method therefore can be used to give a semi-quantitative estimate of meson mass correction in cases when the BSEs are complicated by interactions that go beyond the dominant one.

Recent experiments are shown to operate in the semiclassical regime.

Investigating total collisions of the Newtonian N-body problem on shape space
Creators: name: Reichert, Paula
Publisher: name: arXiv
Year: 2020
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: We analyze the points of total collision of the Newtonian gravitational system on shape space (the relational configuration space of the system). While the Newtonian equations of motion, formulated with respect to absolute space and time, are singular at the point of total collision due to the singularity of the Newton potential at that point, this need not be the case on shape space where absolute scale doesn't exist. We investigate whether, adopting a relational description of the system, the shape degrees of freedom, which are merely angles and their conjugate momenta, can be evolved through the points of total collision. Unfortunately, this is not the case. Even without scale, the equations of motion are singular at the points of total collision (and only there). This follows from the special behavior of the shape momenta. While this behavior induces the singularity, it at the same time provides a purely shape-dynamical description of total collisions. By help of this, we are able to discern total-collision solutions from non-collision solutions on shape space, that is, without reference to (external) scale. We can further use the shape-dynamical description to show that total-collision solutions form a set of measure zero among all solutions.

title: Re-contextualising Consumer Escapism
title: Binge-watching and the Unexpected Effects of an Escape
titleType: Subtitle
Creators: name: Jones, Scott
Publisher: name: Lancaster University
Year: 2021

description: The aim of this doctoral thesis is to deepen and expand the contextualisation of consumer escapism and the research recognises that personal experiences influence and impact on escapism as do more distant and remote events that take place in the wider world. Much of the extant work in the Consumer Culture Theory (CCT) tradition of consumer research has explored escapism in terms of investigating extraordinary experiences and framing an escape as something that is different and separate to everyday life. Drawing upon the context of binge-watching, this thesis explores how escapism is integrated and woven within consumers’ everyday lives, taking place in mundane contexts that we live within. This thesis sets out to interrogate the nature and character of self-electing to tune in and get lost in narratives over extended periods of time and immersion to develop new theoretical concepts to address this form of escapism. The context for this study was a three-year (2016-2019) micro-ethnographic study of consumer’s binge-watching of TV shows, particularly the Netflix political drama, House of Cards (2013-18). The methods used to triangulate the data include semi-structured in-depth interviews, subjective personal introspection, diary entries, telephonic communications and use of videographic and visual materials. The emergent findings show that escapism is pervasive, interacting with our thoughts, fantasies, imaginations and linked to our interests like fandom. To experience an escape is contingent on various preconditions being met. This thesis makes contributions to our understanding of how consumers seek out and experience an escape and accounts for an escape lasting beyond the point of consumption. The research theorises how an escape can deliver unexpected outcomes that consumers may not necessarily expect. The thesis is presented in alternative format with four of its chapters being delivered as research articles. Each article presents specific research objectives which stem from the overall aim of the study.

description: The first epitaxial ferroelectric wurtzite film with clear polarization-electric field hysteresis behavior is presented. The coercive field of this epitaxial Al0.7Sc0.3N film on W/c-sapphire substrate is 0.4 +- 0.3 MV cm-1 (8 %) smaller than that of a conventional fiber textured film on a Pt/TiOx/SiO2/Si substrate, attributed to the 0.01 +- 0.007 Å smaller c-axis lattice parameter in the epitaxial film. The strain and decrease of the coercive field most likely originate from epitaxial strain rather than the mismatch in thermal coefficient of expansion. These results provide an insight for further coercive field reduction of novel wurtzite ferroelectrics using epitaxial mismatch strain.

description: We report on deep XMM-Newton and NuSTAR observations of the high redshift, z=2.94, extremely red quasar (ERQ), SDSS J165202.60+172852.4, with known galactic ionized outflows detected via spatially-resolved [OIII] emission lines. X-ray observations allow us to directly probe the accretion disk luminosity and the geometry and scale of the circumnuclear obscuration. We fit the spectra from the XMM-Newton/EPIC and NuSTAR detectors with a physically motivated torus model and constrain the source to exhibit a near Compton-thick column density of $N_H=(1.02^{+0.76}_{-0.41})\times10^{24}\textrm{ cm}^{-2}$, a near edge-on geometry with the line-of-sight inclination angle of $θ_i=85^{\circ}$, and a scattering fraction of $f_{sc}\sim 3$ %. The absorption-corrected, intrinsic 2-10 keV X-ray luminosity of $L_{\textrm{2-10}}=(1.4^{+1}_{-1}) \times10^{45} \textrm{ erg s}^{-1}$ reveals a powerful quasar that is not intrinsically X-ray weak, consistent with observed trends in other ERQs. We also estimate the physical properties of the obscuration, although highly uncertain: the warm ionized scattering density of $n_e \sim 7.5\times(10^2-10^3)\textrm{ cm}^{-3}$ and the obscuration mass of $M_{obsc} \sim 1.7\times(10^4-10^6) M_{\odot}$. As previously suggested with shallower X-ray observations, optical and infrared selection of ERQ has proved effective in finding obscured quasars with powerful outflow signatures. Our observations provide an in-depth view into the X-ray properties of ERQs and support the conclusions of severely photon-limited studies of obscured quasar populations at high redshifts.

DISTRIBUTION.— Borneo (Kalimatan and Sarawak). See comment below.
NATURAL HISTORY.— Not reported.
COMMENTS.— Preceding information extracted from Peters (1871) and predominantly from Inger (1966). Peters’ description is brief and incomplete for diagnostic purposes. Inger’s account is detailed and includes a second adult male that he discovered in the Rijksmuseum in Leiden. The latter specimen also had specific locality information, “Semedum,” which the holotype did not.
In a 1894 report on a small herpetological collection from one of the Mentawei Islands. Boulenger identified a juvenile specimen (23 mm SVL) and declared that it closely matched Peters’ description of K. punctatus. I believe this identification is erroneous and highly unlikely for a Borneo frog to occur in the distant Mentawei Islands.

description: We evaluate the complex frequencies of the normal modes for the massive charged scalar field perturbations around a Reissner-Nördstrom black hole surrounded by a static and spherically symmetric quintessence using third order WKB approximation approach. Due to the presence of quintessence, quasinormal frequencies damp more slowly. We studied the variation of quasinormal frequencies with charge of the black bole, mass and charge of perturbating scalar field and the quintessential state parameter.

description: We present early results from our project to investigate if there is a relationship between the mass-loss rates of AGB stars and the chemistry within the circumstellar envelopes that this process creates. We have obtained high spectral resolution (R > 60,000) observations with the Echelon Cross Echelle Spectrograph (EXES) aboard SOFIA of a small sample of C, M, and S-type AGB stars. The mass-loss rate of this sample ranges from 10-7 to 10-5 solar masses per year. We have focused on two spectral regions (7.5 & 13—14 μm) that allow us to study several molecules that are either exceedingly difficult to observe from the ground or have no permanent dipole moment.

description: Vehicle shape information is very important in Intelligent Traffic Systems (ITS). In this paper we present a way to exploit a training data set of vehicles released in different years and captured under different perspectives. Also the efficacy of clustering to enhance the make/model classification is presented. Both steps led to improved classification results and a greater robustness. Deeper convolutional neural network based on ResNet architecture has been designed for the training of the vehicle make/model classification. The unequal class distribution of training data produces an a priori probability. Its elimination, obtained by removing of the bias and through hard normalization of the centroids in the classification layer, improves the classification results. A developed application has been used to test the vehicle re-identification on video data manually based on make/model and color classification. This work was partially funded under the grant.

description: Gravitational waves (GW) propagating through a magnetised plasma excite low-frequency magnetohydrodynamic (MHD) waves. In this paper we investigate whether these waves can produce observable radio emission at higher frequencies by scattering on an an-isotropic intrinsically relativistic distribution of electrons and positrons in the force-free wind surrounding a double neutron star binary merger. The relativistic particle distribution is assumed to be strictly along the magnetic field lines, while the magneto-plasma streams out at a relativistic speed from the neutron stars. In the case of Compton scattering of an incident MHD wave transverse to the magnetic field, we find that the probability of scattering to both a transverse x-mode and a quasi-transverse Langmuir-o mode is suppressed when the scattered frequency is below the local relativistic gyro-frequency, i.e. when the magnetic field is very strong.
