description: The process of dynamical decoherence may cause apparent superselection rules, which are sometimes called `environmentally induced' or `soft'. A natural question is whether such dynamical processes are eventually also responsible for at least some of the superselection rules which are usually presented as fundamentally rooted in the kinematical structure of the theory (so called `hard' superselection rules). With this question in mind, I re-investigate two well known examples where superselection rules are usually argued to rigorously exist within the given mathematical framework. These are (1) the Bargmann superselection rule for the total mass in Galilei invariant quantum mechanics and (2) the charge superselection rule in quantum electrodynamics. I argue that, for various reasons, the kinematical arguments usually given are not physically convincing unless they are based on an underlying dynamical process.

description: The near-horizon properties of a black hole are studied within an algebraic framework, using a scalar field as a simple probe to analyze the geometry. The operator H governing the near-horizon dynamics of the scalar field contains an inverse square interaction term. It is shown that the operators appearing in the corresponding algebraic description belong to the representation space of the Virasoro algebra. The operator H is studied using the representation theory of the Virasoro algebra. We observe that the wave functions exhibit scaling behaviour in a band-like region near the horizon of the black hole.

description: Multimodality datasets are becoming increasingly common in various domains to provide complementary information for predictive analytics. One significant challenge in fusing multimodality data is that the multiple modalities are not universally available for all samples due to cost and accessibility constraints. This situation results in a unique data structure called an Incomplete Multimodality Dataset. We propose a novel Incomplete-Multimodality Transfer Learning (IMTL) model that builds a predictive model for each sub-cohort of samples with the same missing modality pattern, and meanwhile couples the model estimation processes for different sub-cohorts to allow for transfer learning. We develop an Expectation-Maximization (EM) algorithm to estimate the parameters of IMTL and further extend it to a collaborative learning paradigm that is specifically valuable for patient privacy preservation in health care applications. We prove two advantageous properties of IMTL: the ability for out-of-sample prediction and a theoretical guarantee for a larger Fisher information compared with models without transfer learning. IMTL is applied to diagnosis and prognosis of Alzheimer’s disease at an early stage called Mild Cognitive Impairment using incomplete multimodality imaging data. IMTL achieves higher accuracy than competing methods without transfer learning.

Static Gravitational Global Monopoles

description: Static solutions in spherical symmetry are found for gravitating global monopoles. Regular solutions lacking a horizon are found for $η< 1/\sqrt{8π}$, where $η$ is the scale of symmetry breaking. Apparently regular solutions with a horizon are found for $1/\sqrt{8π} \le η\alt \sqrt{3/8π}$. Though they have a horizon, they are not Schwarzschild. The solution for $η= 1/\sqrt{8π}$ is argued to have a horizon at infinity. The failure to find static solutions for $η> \sqrt{3/8π} \approx 0.3455$ is consistent with findings that topological inflation begins at $η\approx 0.33$.

description: In a space-time with torsion, the action for the gravitational field can be extended with a parity-violating piece. We show how to obtain such a piece from geometry itself, by suitably modifying the affine connection so as to include a pseudo-tensorial part. A consistent method is thus suggested for incorporating parity-violation in the Lagrangians of all matter fields with spin in a space-time background with torsion.

description: We demonstrate the localisation of quantum well excitons in a periodic array of linear traps using photoluminescence experiments. The excitonic traps are induced by applying spatially alternating external voltages via interdigitated metal gates. The localisation originates from the periodical modulation of the strength of the quantum-confined Stark effect in the plane of the quantum well. In our experiments, the trap depth is easily tuned by the voltages applied to the interdigitated gates. Furthermore, we find that a perpendicular magnetic field reduces the exciton diffusion length. In short-period lateral superlattices, we observe a magnetic-field-induced stabilisation of excitons in the presence of strong in-plane electric fields.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: For general relativistic spacetimes filled with irrotational `dust' a generalized form of Friedmann's equations for an `effective' expansion factor $a_D (t)$ of inhomogeneous cosmologies is derived. Contrary to the standard Friedmann equations, which hold for homogeneous-isotropic cosmologies, the new equations include the `backreaction effect' of inhomogeneities on the average expansion of the model. A universal relation between `backreaction' and average scalar curvature is also given. For cosmologies whose averaged spatial scalar curvature is proportional to $a_D^{-2}$, the expansion law governing a generic domain can be found. However, as the general equations show, `backreaction' acts as to produce average curvature in the course of structure formation, even when starting with space sections that are spatially flat on average.

description: Non--minimal repulsive singularities (``repulsons'') in extended supergravity theories are investigated. The short distance antigravity properties of the repulsons are tested at the classical and the quantum level by a scalar test--particle. Using a partial wave expansion it is shown that the particle gets totally reflected at the origin. A high frequency incoming particle undergoes a phase shift of $\fracπ{2}$. However, the phase shift for a low--frequency particle depends upon the physical data of the repulson. The curvature singularity at a finite distance $r_h$ turns out to be transparent for the scalar test--particle and the coordinate singularity at the origin serves as a repulsive barrier at which particles bounce off.

We argue that network models are particularly suited for the investigation of the dynamics of disordered systems.

description: A complete set of Feynman rules is derived, which permits a perturbative description of the nonequilibrium dynamics of a symmetry-breaking phase transition in $λϕ^4$ theory in an expanding universe. In contrast to a naive expansion in powers of the coupling constant, this approximation scheme provides for (a) a description of the nonequilibrium state in terms of its own finite-width quasiparticle excitations, thus correctly incorporating dissipative effects in low-order calculations, and (b) the emergence from a symmetric initial state of a final state exhibiting the properties of spontaneous symmetry breaking, while maintaining the constraint $\equiv 0$. Earlier work on dissipative perturbation theory and spontaneous symmetry breaking in Minkowski spacetime is reviewed. The central problem addressed is the construction of a perturbative approximation scheme which treats the initial symmetric state in terms of the field $ϕ$, while the state that emerges at later times is treated in terms of a field $ζ$, linearly related to $ϕ^2$. The connection between early and late times involves an infinite sequence of composite propagators. Explicit one-loop calculations are given of the gap equations that determine quasiparticle masses and of the equation of motion for $$ and the renormalization of these equations is described. The perturbation series needed to describe the symmetric and broken-symmetry states are not equivalent, and this leads to ambiguities intrinsic to any perturbative approach. These ambiguities are discussed in detail and a systematic procedure for matching the two approximations is described.

description: We quantize the spherically symmetric sector of generic charged black holes. Thermal properties are encorporated by imposing periodicity in Euclidean time, with period equal to the inverse Hawking temperature of the black hole. This leads to an exact quantization of the area (A) and charge (Q) operators. For the Reissner-Nordström black hole, $A=4πG \hbar (2n+p+1)$ and $Q=me$, for integers $n,p,m$. Consistency requires the fine structure constant to be quantized: $e^2/\hbar=p/m^2$. Remarkably, vacuum fluctuations exclude extremal black holes from the spectrum, while near extremal black holes are highly quantum objects. We also prove that horizon area is an adiabatic invariant.

Spectral statistics and periodic orbits

description: The main purpose of these lectures is to discuss briefly recent methods of calculation of statistical properties of quantum eigenvalues for chaotic systems based on semi-classical trace formulas. Under the assumption that periodic orbit actions are non-commensurable it is demonstrated by a few different methods that the spectral statistics of chaotic systems without time-reversal invariance in the universal limit agrees with statistics of the Gaussian Unitary Ensemble of random matrices. The methods used permit to obtain not only the limiting statistics but also the way the spectral statistics of dynamical systems tends to the universal limit. The statistics of the Riemann zeta function zeros is considered in details.

Observables and gauge invariance in the theory of non-linear spacetime perturbations

description: We discuss the issue of observables in general-relativistic perturbation theory, adopting the view that any observable in general relativity is represented by a scalar field on spacetime. In the context of perturbation theory, an observable is therefore a scalar field on the perturbed spacetime, and as such is gauge invariant in an exact sense (to all orders), as one would expect. However, perturbations are usually represented by fields on the background spacetime, and expanded at different orders into contributions that may or may not be gauge independent. We show that perturbations of scalar quantities are observable if they are first order gauge-invariant, even if they are gauge dependent at higher order. Gauge invariance to first order plays therefore an important conceptual role in the theory, for it selects the perturbations with direct physical meaning from those having only a mathematical status. The so-called ``gauge problem'', and the relationship between measured fluctuations and gauge dependent perturbations that are computed in the theory are also clarified.

description: As a famous plateau lake and a place rich in biodiversity located at the Hengduan Mountains, there is little research on microbial diversity and community composition in Erhai. In this study, 770,425 16S rRNA sequences had obtained at different depth samples. The abundance‐based coverage estimates (ACE), Chao1, and Shannon indices indicated the high abundance and diversity of Erhai sediment microorganisms. And they were obviously affected by human disturbance. Gammaproteobacteria, Deltaproteobacteria, Bacteroidia, Anaerolineae, Phycisphaerae, and Methanomicrobia were dominant bacteria and existed in almost all samples. The content of total nitrogen (TN) in sediments had a significant positive correlation between Syntrophus, Deltaproteobacteria, Desulfatiglans, Oxyphotobacteria, Clostridiales, Burkholderiaceae, Geobacter, Crenothrix species richness. Desulfobacca, Syntrophus, Deltaproteobacteria, Desulfatiglans, Gammaproteobacteria, Oxyphotobacteria, and Clostridiales were positively correlated with the nitrates in sediments. And the species richness of Desulfatiglans was correlated with NO2-. The RDA analysis was shown that dbRDA1 was affected mainly by the depth of lake, while the content of TN, NO3−, NO2−, and NH4+ had the largest effect on dbRDA2. The results indicated the great relations between the diversity and composition of microbial communities and different forms of sediment nitrogen in Erhai lake sediments.

Then, we review the main ideas of the Horava-Witten theory which is a strong coupling limit of heterotic superstring theory. Using the conformal relationship between these two theories we present Kasner asymptotic solutions of Bianchi type IX geometries within these theories and make predictions about possible emergence of chaos. Finally, we present a possible method of generating Horava-Witten cosmological solutions out of the well-known general relativistic pre-big-bang solutions.

description: Diffractive systems are quantum-mechanical models with point-like singularities where usual semiclassical approximation breaks down. An overview of recent investigations of such systems is presented. The following examples are considered in details: (i) billiards (both integrable and chaotic) with small-size scatterers, (ii) pseudo-integrable polygonal plane billiards, and (iii) billiards with the Bohr-Aharonov flux lines. First, the diffractive trace formulas are discussed with particular emphasis on models where the diffractive coefficient diverges in certain directions. Second, it is demonstrated that the spectral statistics of diffractive models are different from the statistics of both integrable and chaotic systems. The main part of the paper is devoted to analytical calculations of spectral statistics for certain diffractive models.

Classical back reaction of low-frequency cosmic gravitational radiation

description: We study in a Brill-Hartle type of approximation the back reaction of a superposition of linear gravitational waves on the mean gravitational field up to second order in the wave amplitudes. The background field is taken as an Einstein-deSitter geometry. In order to follow inflationary scenarios, the wavelengths are allowed to exceed the temporary Hubble distance. As in optical coherence theory, the wave amplitudes are considered as random variables, which form a homogeneous and isotropic stochastic process, sharing the symmetries of the background metric. The effective stress-energy tensor for the random waves is calculated in terms of correlation functions and covers subhorizon as well as superhorizon modes, the latter give in many cases negative contributions to energy density and pressure. We discuss solutions of the second-order equations including pure gravitational radiation universes.

The modulation of enteropathogenic E. coli infection by substrate stiffness
Creators: name: Abou Samra, Antonella
Publisher: name: No Publisher Supplied
Year: 2021

description: Enteropathogenic Escherichia coli (EPEC) is a Gram-negative foodborne bacterium that has been associated with many severe diarrhea outbreaks worldwide, especially in children under the age of five. EPEC is a pathogen that infects intestinal epithelial cells and causes several conditions ranging from asymptomatic colonization of the intestine to morbidity and even lethality. A hallmark of an EPEC infection is the formation of “attaching and effacing” histopathological lesions at the surface of enterocytes that are characterized by the destruction of the brush border microvilli and the formation of actin-rich pedestals beneath the bacterial attachment site. Like many Gram-negative bacteria, EPEC employs the Type III Secretion System (T3SS) to inject effector proteins essential for its infectivity, including its own receptor Tir, that lead to host cell cytoskeletal remodeling and promote the formation of these actin pedestals and intimate bacteria-host cell adherence. In addition to Tir, EPEC injects several other effector proteins that lead to various pathological phenotypes such as tight junction disruption, cell cycle arrest and apoptotic cell death. EPEC infection has been extensively studied using traditional tissue culture models; however, intestinal stiffness is more than 300,000 times softer than glass. Studying EPEC using polyacrylamide gels of physical compliance can provide a deeper understanding on its infection mechanism under mechanical conditions closer to its natural environment. Since substrate stiffness has known physiological effects on mammalian cytoskeletal organization and cell signaling, we hypothesize that tissue compliance will play an important role in the regulation of EPEC infection.

STOCK MARKET DEVELOPMENT AND ITS INFLUENCE ON ECONOMIC GROWTH IN NIGERIA
Creators: name: Olufemi Michael, Adekunle
Publisher: name: keith journal
Year: 2025
Subjects: Stock Market, Economic Growth, Development, Nigeria

description: This study examined the impact of the Nigerian Stock market development on the nation’s economic growth from 1985 to 2014. The economic growth was proxy by the GDP while the stock market variables considered included; market capitalization and market turnover ratio as proxy for stock market development in terms of size and liquidity. The study utilizes the Johansson’s co integration test in establishing if a long run relationship does exist between stock market development and economic growth in Nigeria. The empirical results suggest that the stock market is significant in determining economic growth in Nigeria using the error correlation model and it was found that the stock market has impacted insignificantly on the economic growth. It is recommended that policy makers should ensure improvement in the market capitalization, by encouraging foreign direct investment participation in the market. Small and medium entrepreneurs should be encouraged to access the market for investible funds given their close affinity with the grass root funds mobilization ability.

Transcript of Priscilla Wakefield's journal 1798-1799.docx
Creators: name: Graham, Ruth
Publisher: name: figshare
Year: 2019
Subjects: History

description: These are 460 entries from the journal or diary of Priscilla Wakefield (1751-1832) for the years 1798 to 1799 in chronological order with notes. This transcript is derived from a combination of two sources. The first has been described as the Black Volume. It is available on a microfilm held in the Alexander Turnbull Library, New Zealand Micro-MS-0927-04 and covers the years 1798-1799 and 1807. It is proported to be a handwritten copy of the originals that were in the possession of Rev. Vincent Henry Stanton (1846-1924). The second source is a TS transcript of the Black Volume probably done by Lady Chapman in preparation for her work. This is available at the Alexander Turnbull Library on microfilm at Micro-MS-0927-02 or paper MS-Papers-9512-60. The transcript has a number of unidentified words.

Numerical Observation of a Tubular Phase in Anisotropic Membranes

Year: 1997
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We provide the first numerical evidence for the existence of a tubular phase, predicted by Radzihovsky and Toner (RT), for anisotropic tethered membranes without self-avoidance. Incorporating anisotropy into the bending rigidity of a simple model of a tethered membrane with free boundary conditions, we show that the model indeed has two phase transitions corresponding to the flat-to-tubular and tubular-to-crumpled transitions. For the tubular phase we measure the Flory exponent $ν_F$ and the roughness exponent $ζ$. We find $ν_F=0.305(14)$ and $ζ=0.895(60)$, which are in reasonable agreement with the theoretical predictions of RT --- $ν_F=1/4$ and $ζ=1$.

description: The SO(4,1) gauge-invariant theory of the Dirac fermions in the external field of the Kaluza-Klein monopole is investigated. It is shown that the discrete quantum modes are governed by reducible representations of the o(4) dynamical algebra generated by the components of the angular momentum operator and those of the Runge-Lenz operator of the Dirac theory in Taub-NUT background. The consequence is that there exist central and axial discrete modes whose spinors have no separated variables.

description: We consider the most general diffeomorphism invariant action in 1+1 spacetime dimensions that contains a metric, dilaton and Abelian gauge field, and has at most second derivatives of the fields. Our action contains a topological term (linear in the Abelian field strength) that has not been considered in previous work. We impose boundary conditions appropriate for a charged black hole confined to a region bounded by a surface of fixed dilaton field and temperature. By making some simplifying assumptions about the quantum theory, the Hamiltonian partition function is obtained. This partition function is analyzed in some detail for the Reissner-Nordstrom black hole and for the rotating BTZ black hole.
