description: The Baker-Akhiezer (BA) function theory was successfully developed in the mid 1970s. This theory brought very interesting and important results in the spectral theory of almost periodic operators and theory of completely integrable nonlinear equations such as Korteweg-de Vries equation, nonlinear Schrödinger equation, sine-Gordon equation, Kadomtsev-Petviashvili equation. Subsequently the theory was reproduced for the Ablowitz-Kaup-Newell-Segur (AKNS) hierarchies. However, extensions of the Baker-Akhiezer function for the Maxwell-Bloch (MB) system or for the Karpman-Kaup equations, which contain prescribed weight functions characterizing inhomogeneous broadening of the main frequency, are unknown. The main goal of the paper is to give a such of extension associated with the Maxwell-Bloch equations. Using different Riemann-Hilbert problems posed on the complex plane with a finite number of cuts we propose such a matrix function that has unit determinant and takes an explicit form through Cauchy integrals, hyperelliptic integrals and theta functions. The matrix BA function solves the AKNS equations (the Lax pair for MB system) and generates a quasi-periodic finite-gap solution to the Maxwell-Bloch equations. The suggested function will be useful in the study of the long time asymptotic behavior of solutions of different initial-boundary value problems for the MB equations using the Deift-Zhou method of steepest descent and for an investigation of rogue waves of the Maxwell-Bloch equations.

description: Study of Gene Regulatory Networks (GRNs) is essential for the understanding of developmental processes because GRNs describe the genetic specification mechanisms that instruct an egg to become a complex organism. Additionally, because cell types, organs, tissues, and other morphological features are specified during development, changes to the underlying GRNs lead to differences in such features. Therefore, an understanding of developmental GRNs is required to understand how morphology evolves. Echinoderms offer an attractive group of model organisms for the study of GRN evolution. A variety of echinoderm species have publically available genomic or transcriptomic information, their development is well characterized, and for some species and cell types extensive GRNs have already been elucidated, all of which greatly facilitate comparative approaches. Furthermore, echinoderms are deuterostomes, just as vertebrates are. Therefore, studies of echinoderm developmental GRNs can enhance our understanding of vertebrate evolution and development. Here, we take multiple approaches to understanding the processes of developmental GRN evolution. We first survey recent literature with the aim of ascertaining the significance and prevalence of transcription factor changes to GRN evolution and morphological novelty. Next, we present a recent publication from our lab which describes a previously uncharacterized source of modularity within orthologous Tbrain (Tbr) transcription factor DNA-binding abilities. We maintain that this type of modularity could be an important contributor to the evolution of novel features. After this, we characterize a new GRN for the specification of serotonergic neurons in the sea star dorsal ganglia. This structure exhibits versatile morphologies among echinoderms and is important for understanding the origins of the vertebrate forebrain as it is thought to be similar to the ancestral deuterostome central nervous system precursor. Finally, we propose a new line of research intended to determine whether modular DNA- binding among orthologous Tbr transcription factors has impacted the evolution of this interesting neuronal structure.

description: We compute the leading contribution to the E2/M1 mixing ratio of the decay $Δ\rightarrow Nγ$ in heavy baryon chiral perturbation theory. We find the mixing ratio to be $4\% \ltap |δ_{\rm E2/M1}| \ltap 11\%$, much larger than estimates based on the quark model and other hadronic models. We also compute the mixing ratio for the radiative decay of the hyperon resonances. The decays $Σ^{*+}\rightarrowΣ^+γ$ and $Ξ^{*-}\rightarrowΞ^-γ$ provide a particularly sensitive probe of deviations from heavy baryon spin-flavour SU(6).

description: We complete and improve the fits to experimental $ππ$ scattering amplitudes, both at low and high energies, that we performed in the previous papers of this series. We then verify that the corresponding amplitudes satisfy analyticity requirements, in the form of partial wave analyticity at low energies, forward dispersion relations (FDR) at all energies, and Roy equations below$\bar{K}K$ threshold; the first by construction, the last two, inside experimental errors. Then we repeat the fits including as constraints FDR and Roy equations. The ensuing central values of the various scattering amplitudes verify very accurately FDR and, especially, Roy equations, and change very little from what we found by just fitting data, with the exception of the D2 wave phase shift, for which one parameter moves by $1.5 σ$. These improved parametrizations therefore provide a reliable representation of pion-pion amplitudes with which one can test various physical relations. We also present a list of low energy parameters and other observables. In particular, we find $a_0^{(0)}=0.223\pm0.009 M^{-1}_π$, $a_0^{(2)}=-0.0444\pm0.0045 M^{-1}_π$ and $δ_0^{(0)}(m^2_K)-δ_0^{(2)}(m^2_K)=50.9\pm1.2^{\rm o}$.

description: The appealing feature of molecular electronics is the possibility of exploiting functionality built within a single molecule. This functionality can be employed, for example, for sensing or switching purposes. Thus, ideally, the associated conductance changes should be sizable upon application of external stimuli. Here, we show that a molecular spring can be mechanically compressed or elongated to tune its conductance by up to an order of magnitude by controlling the quantum interference between electronic pathways. Oscillations in the conductance occur when the stress built up in the molecule is high enough to allow the anchoring groups to move along the surface in a stick-slip-like fashion. The mechanical control of quantum interference effects and the resulting large change in molecular conductance open the door for applications in, e.g., a minute mechanosensitive sensing device functional at room temperature.

description: The twisted G/H models are constructed as twisted supersymmetric gauged WZW models. We analyze the case of $G=SU(N)$, $H=SU(N_1)\times ...\times SU(N_n)\times U(1)^r$ with $rank\ G =\ rank\ H$, and discuss possible generalizations. We introduce a non-abelian bosonization of the $(1,0)$ ghost system in the adjoint of $H$ and in G/H. By computing chiral anomalies in the latter picture we write the quantum action as a decoupled sum of ``matter", gauge and ghost sectors. The action is also derived in the unbosonized version. We invoke a free field parametrization and extract the space of physical states by computing the cohomology of $Q$ , the sum of the BRST gauge-fixing charge and the twisted supersymmetry charge. For a given $G$ we briefly discuss the relation between the various G/H models corresponding to different choices of $H$. The choice $H=G$ corresponds to the topological G/G theory.

Phenomenographic research on adult students’ experiences of learning and conceptualisations of success in their online postgraduate programmes
Creators: name: Rotar, Olga
Publisher: name: Lancaster University
Year: 2021

description: The rapid development of online distance programmes has increased the popularity of higher education among adult students. Despite the suggested benefits of online higher education (OHE), adults may experience various challenges and barriers when adapting to it. Yet, research tends to oversimplify adults’ learning experiences to fit historical assumptions. This study examines qualitatively different ways of experiencing online learning and conceptualising success by adult students. A detailed picture of these variations was drawn from primary interviews made with the participants of two online postgraduate programmes. The chosen phenomenographic research design embeds a principle of diversity, assisting in uncovering qualitative variations in students’ accounts and leading to two hierarchically structured models. In response to research question one, the analysis demonstrated three ways of experiencing online learning: as an investment, as a process that brings structure, and as a process that enables and empowers. The context in which learning is conceptualised is proposed to explain the identified variations. The second research question uncovered the structure of the concept of success, in which a more complex perspective on success - success as self-actualisation - embraced the features of more simplistic ones. To highlight the nature of identified variations and situatedness of adult students’ learning aspirations, I provide an analysis of contextual backgrounds within which the notions of success has been discussed. Research question three hypothesises relationships between two phenomena under question. Within the confines of levels of evidence collected in this study, generalisations cannot be made, but it provides a more detailed empirically grounded picture of the phenomenon of online learning as experienced by adult students than it has been previously offered. Furthermore, it offers a holistic view of students’ diverse conceptualisations of success. In this way, the study makes a distinctive contribution to the research literature on adult students’ learning experiences in OHE and to discourse on student success.

description: We present new results of the search for WH to lepton neutrino b b production in ppbar collisions at a center of mass energy of sqrt{s}=1.96 TeV, based on a dataset with integrated luminosity of 0.44 fb-1. We combine these new results with previously published searches by the D0 collaboration, for WH and ZH production analyzed in the MET b b final state, for ZH (to l+l- b b) production, for WH (to WWW) production, and for H (to WW) direct production. No signal-like excess is observed either in the WH analysis or in the combination of all D0 Higgs boson analyses. We set 95% C.L. (expected) upper limits on to 1.9 (3.3) pb for Higgs boson masses between 105 and 145 GeV, to be compared to the theoretical prediction of 0.13 pb for a standard model (SM) Higgs boson with mass m_H=115 GeV. After combination with the other D0 Higgs boson searches, we obtain for m_H=115 GeV an observed (expected) limit 8.5 (12.1) times higher than the SM predicted Higgs boson production cross section. For m_H=160 GeV, the corresponding observed (expected) ratio is 10.2 (9.0).

description: Relative surprise regions are shown to minimize, among Bayesian credible regions, the prior probability of covering a false value from the prior. Such regions are also shown to be unbiased in the sense that the prior probability of covering a false value is bounded above by the prior probability of covering the true value. Relative surprise regions are shown to maximize both the Bayes factor in favor of the region containing the true value and the relative belief ratio, among all credible regions with the same posterior content. Relative surprise regions emerge naturally when we consider equivalence classes of credible regions generated via reparameterizations.

Evolution and Regularity Results for Epitaxially Strained Thin Films and Material Voids

description: In this dissertation we study free boundary problems that model the evolution of interfaces in the presence of elasticity, such as thin film profiles and material void boundaries. These problems are characterized by the competition between the elastic bulk energy and the anisotropic surface energy. First, we consider the evolution equation with curvature regularization that models the motion of a two-dimensional thin film by evaporation-condensation on a rigid substrate. The film is strained due to the mismatch between the crystalline lattices of the two materials and anisotropy is taken into account. We present the results contained in [62] where the author establishes short time existence, uniqueness and regularity of the solution using De Giorgi’s minimizing movements to exploit the L2 -gradient flow structure of the equation. This seems to be the first analytical result for the evaporation-condensation case in the presence of elasticity. Second, we consider the relaxed energy introduced in [20] that depends on admissible pairs (E, u) of sets E and functions u defined only outside of E. For dimension three this energy appears in the study of the material voids in solids, where the pairs (E, u) are interpreted as the admissible configurations that consist of void regions E in the space and of displacements u of the atoms of the crystal. We provide the precise mathematical framework that guarantees the existence of minimal energy pairs (E, u). Then, we establish that for every minimal configuration (E, u), the function u is C 1,γ loc -regular outside an essentially closed subset of E. No hypothesis of starshapedness is assumed on the voids and all the results that are contained in [18] hold true for every dimension d ≥ 2.

description: We present a study of four muon, four electron, and two muon two electron events using 1 fb^(-1) of data collected with the D0 detector at the Fermilab Tevatron p-barp Collider at sqrt(s) = 1.96 TeV. Requiring the lepton pair masses to be greater than 30 GeV, we observe one event, consistent with the expected background of 0.13 +- 0.03 events and with the predicted standard model ZZ and Zγ^* production of 1.71 +-0.15 events. We set an upper limit on the ZZ and Zγ^* cross section of 4.4 pb at the 95% C.L. We also derive limits on anomalous neutral trilinear ZZZ and ZZγ^* gauge couplings. The one-parameter 95%$ C.L. coupling limits with a form factor scale Lambda = 1.2 TeV are -0.28 < f_(40)^Z < 0.28, -0.31 < f_(50)^Z < 0.29, -0.26 < f_(40)^γ< 0.26, and -0.30 < f_(5 0)^γ< 0.28.

description: The side effects of antibiotics on humans and ambient environment have aroused huge attention from related researchers. In this article, the performances and mechanism of photodegradation of tetracycline (TC) were examined by employing semiconducting polymer microspheres obtained with an emulsion-solvent-evaporation approach. Under the excitation of visible-light, as-prepared semiconducting polymer microspheres show outstanding photocatalytic ability and excellent stability for TC-derived antibiotics. Compared with corresponding semiconducting polymer powders, the adsorption and photocatalytic rates of TC by polymer-based microspheres increased by 8.07 and 6.79 times, respectively. These performance improvements in photodegradation are mainly ascribed to the larger specific surface area and longer conjugation length of as-prepared spherical structure. Characterization of electron spin resonance demonstrates that the primary active species functioning for efficient photodegradations of TC are superoxide radical, hydrogen peroxide, and hole. These results indicated that semiconducting polymer microspheres can serve as efficient photocatalysts for removing destructive TC-derived antibiotics from wastewaters.

description: A general research data repository is supposed to be intuitively usable for a large variety of users with different backgrounds, needs, and expectations. These come to the fore in the design of the interface as secondary features. While the primary features expressed by the core functionality in the scalability, the retrieval time, or the size of the data to be processed is perceived as an absolute must-have, secondary features are perceived as a real advantage 'nice-to-have'. Yet the one depends crucially on the other. We like to share our experience of configuring a research data repository, designing the technical infrastructure, and adding software functionality. By describing the process of making adjustments and their intended results on the usage behavior, we propose a use case of setting up a general research data repository in which the needs of the user play a central role.
Narratives of voice hearing and mental health
Creators: name: Tomlinson, Amy
Publisher: name: Lancaster University
Year: 2021

description: This thesis focuses on the experience of voice hearing and effects on mental health and wellbeing. It is composed of two separate papers: a systematic literature review and an empirical paper. Section one, the paper titled “Understanding indicators of clinical need and methods of reducing distress for children who hear voices: A Systematic Literature Review” aimed to establish the current research base which focuses specifically on the experience of voice hearing in children and the factors related to their current emotional health. The paper synthesised 13 quantitative studies. The majority of studies looked at different factors and two studies detailed interventions. The findings of the review suggest traumatic life events and cognitive appraisals may be important in the experience of distressing voice hearing. However no firm conclusions could be drawn due to small sample sizes and the variable quality of the included articles. There was some indication of CBT strategies being useful in mitigating distress however more evidence is needed. More research taking a consistent approach needs to be conducted in this area to establish the factors that may make some children who hear voices more vulnerable to experiencing distress and how they can be supported to manage their experiences. Section two, the empirical paper titled, “‘I have finally realised I’m not crazy’: A narrative analysis of mental health and mediumship’”, aimed to explore how unusual experiences develop over time and how these experiences come to be seen as mediumistic. A data set of 14 interviews with mediums originating from a qualitative, pluralistic project was re-analysed using narrative analysis to consider how mediums view their experiences in relation to their own mental health. Findings show that mediums’ early experiences were often traumatic and builds on previous research by demonstrating that attempts to fit in with social norms particularly around ‘healthy’ and ‘sane’ increases this trauma and distress. Participants sought out support from key figures, and validating responses were important for them to accept and establish their mediumistic identity.

description: When combining data sets to perform parameter inference, the results will be unreliable if there are unknown systematics in data or models. Here we introduce a flexible methodology, BACCUS: BAyesian Conservative Constraints and Unknown Systematics, which deals in a conservative way with the problem of data combination, for any degree of tension between experiments. We introduce hyperparameters that describe a bias in each model parameter for each class of experiments. A conservative posterior for the model parameters is then obtained by marginalization both over these unknown shifts and over the width of their prior. We contrast this approach with an existing hyperparameter method in which each individual likelihood is scaled, comparing the performance of each approach and their combination in application to some idealized models. Using only these rescaling hyperparameters is not a suitable approach for the current observational situation, in which internal null tests of the errors are passed, and yet different experiments prefer models that are in poor agreement. The possible existence of large shift systematics cannot be constrained with a small number of data sets, leading to extended tails on the conservative posterior distributions. We illustrate our method with the case of the $H_0$ tension between results from the cosmic distance ladder and physical measurements that rely on the standard cosmological model.

description: The reduction kinetics of N,N′-phenylenebis(salicylideneiminato)iron(III), [Fe(salphen)]+ by thioglycolic acid (TSH) has been carried out in mixed aqueous medium (DMSO:H2O; 1:4) in pseudo-first order condition at 26 ± 1 °C. A CORNING colorimeter 253 was used to monitor the reaction rates by detecting the absorbance reduction of the reaction at 435 nm. The reaction was acid independent, second order overall and demonstrated zero Brønsted-Debye salt effect. Ions such as Mg2+ and CH3COO- catalyzed the reaction. The thermodynamic parameters indicated an activated complex that is much ordered and a highly solvated transition state. Reaction catalysis was observed in the case of sodium dodecylsulphate (SDS) and cetyltrimethylammonium bromide (CTAB) inclusion. The critical micelle concentrations obtained for SDS were 8.0 × 10−3 and 3.3 × 10−3 mol dm−3 whereas that observed for CTAB were 2.0 × 10−3 and 2.8 × 10−3 mol dm−3 in water and [Fe(salphen)]+ reaction media respectively. Piszkiewicz model was used to analyze the results which indicated the existence of pre-micellar aggregates and significant electrostatic and hydrophobic interactions between the metal complex and the pre-micellar aggregates of the surfactants. The cooperativity index and binding constants obtained were n = 1.22, K = 4.78 × 104 dm3 mol−1, n = 1.27 and K = 4.55 × 104 dm3 mol−1 respectively for SDS and CTAB. A plausible mechanism suggesting an outer-sphere mechanism has been postulated.

description: People make a range of everyday decisions about how and whether to share content with different people, across different platforms and services, during a variety of tasks. These sharing decisions can encompass complex preferences and a variety of access-control dimensions. In this thesis I examine potential methods for improving sharing mechanisms by better understanding the everyday online sharing environment and evaluating a potential sharing tool. I first present two studies that explore how current sharing mechanisms may fall short on social networking sites, leading to suboptimal outcomes such as regret or self censorship. I discuss the implications of these suboptimal outcomes for the design of behavioral nudging tools and the potential for improving the design of selective-sharing mechanisms. I then draw on a third study to explore the broader “ecosystem” of available channels created by the services and platforms people move between and combine to share content in everyday contexts. I examine the role of selective-sharing features in the broader audience-driven and task-driven dynamics that drive sharing decisions in this environment. I discuss the implications of channel choice and dynamics for the design of selective-sharing mechanisms. Using insights from current shortfalls and ecosystem-level dynamics I then present a fourth study examining the potential for adding topic-driven sharing mechanisms to Facebook. I use design mockups and a lab-based interview to explore participants’ hypothetical use cases for such mechanisms. I find that these mechanisms could potentially be useful in a variety of situations, but successful implementation would require accounting for privacy requirements and users’ sharing strategies.

description: The two partition functions $p_ω(n)$ and $p_ν(n)$ were introduced by Andrews, Dixit and Yee, which are related to the third order mock theta functions $ω(q)$ and $ν(q)$, respectively. Recently, Andrews and Yee analytically studied two identities that connect the refinements of $p_ω(n)$ and $p_ν(n)$ with the generalized bivariate mock theta functions $ω(z;q)$ and $ν(z;q)$, respectively. However, they stated these identities cried out for bijective proofs. In this paper, we first define the generalized trivariate mock theta functions $ω(y,z;q)$ and $ν(y,z;q)$. Then by utilizing odd Ferrers graph, we obtain certain identities concerning to $ω(y,z;q)$ and $ν(y,z;q)$, which extend some early results of Andrews that are related to $ω(z;q)$ and $ν(z;q)$. In virtue of the combinatorial interpretations that arise from the identities involving $ω(y,z;q)$ and $ν(y,z;q)$, we finally present bijective proofs for the two identities of Andrews-Yee.

description: We study fluctuations of pressure in equilibrium for classical particle systems. In equilibrium statistical mechanics, pressure for a microscopic state is defined by the derivative of a thermodynamic function or, more mechanically, through the momentum current. We show that although the two expectation values converge to the same equilibrium value in the thermodynamic limit, the variance of the mechanical pressure is in general greater than that of the pressure defined through the thermodynamic relation. We also present a condition for experimentally detecting the difference between them in an idealized measurement of momentum transfer.

Evaporation of Metal Crystals

description: A mechanism for vaporization of solid metals involving monatomic ledges on metal crystal surfaces is deduced, and an equation is derived for evaporation rate in terns of the dynamics of these ledges. It is shown that crystal edges are a ready source for monatomic ledges. The limiting expression for the vaporization coefficient of large, perfect crystals is given as a function of pressure and temperature by α = 2/3 (p/pe ) ≠ 1/3, where pe is the equilibrium vapor pressure. The effect of screw dislocation-surface intersections on the limiting expression is developed. An equation is derived giving the perturbation due to such intersections. It is found that experimental results for silver crystals confirm various predictions of the theory. Applications of the results are considered.

description: We find the precise relationship between the loop gas method and the matrix quantum mechanics approach to two-dimensional string theory. The two systems are distinguished by different target spaces ($\Z$ and $\R$, respectively) as far as {\it observables} are concerned. We argue that target space loop correlators should coincide in the two models and demonstrate this for a number of examples. As a consequence some interesting generic observations about the structure of two-dimensional string theory may be made: Restricting to a discrete target space leads to {\it factorization} of amplitudes and thus to very simple sewing rules. It is also demonstrated that the restriction to the discrete target space still allows to calculate the correlation functions of tachyon operators in the unrestricted theory.

description: The modularization of Service Function Chains (SFCs) in Network Function Virtualization (NFV) could introduce significant performance overhead and resource efficiency degradation due to introducing frequent packet transfer and consuming much more hardware resources. In response, we exploit the lightweight and individually scalable features of elements in Modularized SFCs (MSFCs) and propose CoCo, a compact and optimized consolidation framework for MSFC in NFV. CoCo addresses the above problems in two ways. First, CoCo Optimized Placer pays attention to the problem of which elements to consolidate and provides a performance-aware placement algorithm to place MSFCs compactly and optimize the global packet transfer cost. Second, CoCo Individual Scaler innovatively introduces a push-aside scaling up strategy to avoid degrading performance and taking up new CPU cores. To support MSFC consolidation, CoCo also provides an automatic runtime scheduler to ensure fairness when elements are consolidated on CPU core. Our evaluation results show that CoCo achieves significant performance improvement and efficient resource utilization.

Sub-picosecond proton tunnelling in deformed DNA hydrogen bonds under an asymmetric double-oscillator model
Creators: name: Luo, Jingxi
Publisher: name: arXiv
Year: 2018
Subjects: subject: Biological Physics (physics.bio-ph)
subject: FOS: Physical sciences

description: We present a model of proton tunnelling across DNA hydrogen bonds, compute the characteristic tunnelling time (CTT) from donor to acceptor and discuss its biological implications. The model is a double oscillator characterised by three geometry parameters describing planar deformations of the H bond, and a symmetry parameter representing the energy ratio between ground states in the individual oscillators. If the symmetry parameter takes its maximum value of 1, then we recover a known model which produced CTTs too large to be biologically relevant; but this is reduced by up to 40 orders of magnitude as the symmetry parameter is decreased. We discover that unless the symmetry parameter is close to 1 or 0, the proton's CTT under any planar deformation is guaranteed to be below one picosecond, which is a biologically relevant time-scale. This supports theories of links between proton tunnelling and biological processes such as spontaneous mutation.

Putative magnetic quantum criticality in (Sr$_{\text{1-x}}$La$_{\text{x}}$)$_{\text{3}}$Ir$_{\text{2}}$O$_{\text{7}}$

description: (Sr$_{1-x}$La$_x$)$_3$Ir$_2$O$_7$ undergoes a bulk insulator-to-metal transition (IMT) at $x \approx \mathrm{0.04}$. Through careful analysis of previously published data ($x=\mathrm{0.053, 0.061, 0.076}$), we find an extended region below the Debye temperature in which the resistivity appears to scale linearly with temperature. Meanwhile resonant (in)elastic x-ray scattering data ($x=\mathrm{0.065}$) suggest a possible crossover from quantum paramagnetic to quantum critical phenomenology between 100 and 200~K. We put this into context with other results, and propose a possible phase diagram as a function of doping.

Conditions for defocusing around more general metrics in Infinite Derivative Gravity
Creators: name: Edholm, James
Publisher: name: arXiv
Year: 2018
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Infinite Derivative Gravity is able to resolve the Big Bang curvature singularity present in general relativity by using a simplifying ansatz. We show that it can also avoid the Hawking- Penrose singularity, by allowing defocusing of null rays through the Raychaudhuri equation. This occurs not only in the minimal case where we ignore the matter contribution, but also in the case where matter plays a key role. We investigate the conditions for defocusing for the general case where this ansatz applies and also for more specific metrics, including a general Friedmann-Robertson-Walker (FRW) metric and three specific choices of the scale factor which produce a bouncing FRW universe.

description: In this conference published in 1997 some problems on the geodesics of a Lorentzian manifold concerning causality and infinite-dimensional variational methods, are pointed out. Even though a big progress on many of these questions have been carried out since then, some computations in this paper may be useful and have not been published elsewhere. Among them, for example, the following one (Section 3). Consider a spacetime which can be written globally as a product $R x M$, such that the natural vector field associated to the coordinate $t$ in $R$ is timelike. When is this spacetime globally hyperbolic with Cauchy hypersurfaces the slices $t=$ constant?

description: The electromagnetic contribution to the $K^+ - K^0$ mass difference is calculated in the $1/N_c$ approach including the $SU(3)$ breaking contributions due to a non-zero strange quark mass. The short-distance contribution can be unambiguously determined in terms of the known parameters of the next-to-leading order chiral lagrangian. The long distance part is estimated using the $1/N_c$ approach by Bardeen et al. Relatively large corrections are found.

description: In a previous work Baillot and Terui introduced Dual light affine logic (DLAL) as a variant of Light linear logic suitable for guaranteeing complexity properties on lambda calculus terms: all typable terms can be evaluated in polynomial time by beta reduction and all Ptime functions can be represented. In the present work we address the problem of typing lambda-terms in second-order DLAL. For that we give a procedure which, starting with a term typed in system F, determines whether it is typable in DLAL and outputs a concrete typing if there exists any. We show that our procedure can be run in time polynomial in the size of the original Church typed system F term.

Einstein-Podolsky-Rosen steering, depth of steering and planar spin squeezing in two-mode Bose-Einstein condensates

description: We show how one can prepare and detect entanglement and Einstein-Podolsky-Rosen (EPR) steering between two distinguishable groups (modes) of atoms in a Bose-Einstein condensate (BEC) atom interferometer. Our paper extends previous work that developed criteria for two-mode entanglement and EPR steering based on the reduced variances of two spins defined in a plane. Observation of planar spin squeezing will imply entanglement, and sufficient planar spin squeezing implies EPR steering, between the two groups of atoms. By using a two-mode dynamical model to describe BEC interferometry experiments, we show that the two-mode entanglement and EPR steering criteria are predicted to be satisfied for realistic parameters. The reported observation of spin squeezing in these parameter regimes suggests it is very likely that the criteria can be used to infer an EPR steering between mesoscopic groups of atoms, provided the total atom number can be determined to sub-Poissonian uncertainty. The criteria also apply to a photonic Mach-Zehnder interferometer. Finally, we give a method based on the amount of planar spin squeezing to determine a lower bound on the number of particles that are genuinely comprise the two-mode EPR steerable state - the so-called two-mode EPR steering depth.

One-loop effective brane action

Subjects: subject: High Energy Physics - Theory (hep-th)

description: The one-loop effective action for a $p$ brane embedded in a $D=p+2$ Minkowski spacetime in the static gauge is calculated. Rescaling the quantum fluctuation by $\sqrt{-g_0}$ evaluated on the background brane leads to the one-loop effective action expressed only in terms of infrared and ultraviolet divergent geometric scalars. After the infrared divergences are absorbed into the quantum fluctuation, there remains the finite number of ultraviolet divergences. This implies that the $D=p+2$ Poincaré symmetry and the $D=p+1$ general coordinate invariance are preserved in one-loop order.
