description: Consider an arrangement of
      hyperplanes and assign to each hyperplane a weight. By using
      this weights Varchenko defines a bilinear form on the vector
      space freely generated by the regions of the arrangement. We
      define this bilinear form for cones of the arrangement. Then
      we show that the determinant of the matrix of the bilinear
      form restricted to the cone is determined by the
      combinatorics of the arrangement inside the cone and factors
      nicely. The resulting theorem induces Varchenko's thereom
      about the determinant of the matrix of the Varchenko bilinear
      form. We consider cones of the braid arrangement which are
      defined by partially ordered sets. We give a formular for the
      determinant of a matrices of the bilinear form restricted to
      one this cones by using properties of the partially ordered
      set.

      Hyperebenen und weise jeder Hyperebene ein Gewicht zu. Unter
      Verwendung dieser Gewichte definiert Varchenko eine
      Bilinearform auf den frei von den Gebieten des Arrangements
      erzeugten Vektorraumes. Wir definieren diese Bilinearform für
      Kegel des Arrangements und zeigen, dass die Determinante der
      Matrix der auf den Kegel eingeschränkten Bilinearform durch
      die Kombinatorik des Arrangements im Kegel bestimmt ist und
      schön faktorisiert. Das resultierende Theorem umfasst
      Varchenkos Theorem über die Determinante der Matrix der
      Varchenko Bilinearform. Wir betrachten Kegel des Braid
      Arrangements, die durch partiell geordnete Mengen definiert
      werden. Wir geben eine Formel für die Determinante der Matrix
      der Bilinearformen, die durch einen solchen Kegel definiert
      ist, und verwenden hierfür Eigenschaften der partiell
      geordneten Menge.

description: We investigate the level of fine-tuning of neutralino Dark Matter below 200 GeV in the low-energy phenomenological minimal supersymmetric Standard Model taking into account the newest results from XENON100 and the Large Hadron Collider as well as all other experimental bounds from collider physics and the cosmological abundance. We find that current and future direct Dark Matter searches significantly rule out a large area of the untuned parameter space, but solutions survive which do not increase the level of fine-tuning. As expected, the level of tuning tends to increase for lower cross-sections, but regions of resonant neutralino annihilation still allow for a band at light masses, where the fine-tuning stays small even below the current experimental limits for direct detection cross-sections. For positive values of the supersymmetric Higgs mass parameter μlarge portions of the allowed parameter space are excluded, but there still exist untuned solutions at higher neutralino masses which will essentially be ruled out if XENON1t does not observe a signal.For negative μuntuned solutions are not much constrained by current limits of direct searches and, if the neutralino mass was found outside the resonance regions, a negative μ-term would be favored from a fine-tuning perspective. Light stau annihilation plays an important role to fulfill the relic density condition in certain neutralino mass regions. Finally we discuss, in addition to the amount of tuning for certain regions in the neutralino mass-direct detection cross-section plane, the parameter mapping distribution if the allowed model parameter space is chosen to be scanned homogeneously (randomized).

description: We provide a description of the Drinfeld-Sokolov Hamiltonian reduction for the construction of classical W-algebras within the framework of Poisson vertex algebras. In this context, the gauge group action on the phase space is translated in terms of (the exponential of) a Lie conformal algebra action on the space of functions. Following the ideas of Drinfeld and Sokolov, we then establish under certain sufficient conditions the applicability of the Lenard-Magri scheme of integrability and the existence of the corresponding integrable hierarchy of bi-Hamiltonian equations.

description: We consider a multidimensional Ito semimartingale regularly sampled on [0,t] at high frequency $1/Δ_n$, with $Δ_n$ going to zero. The goal of this paper is to provide an estimator for the integral over [0,t] of a given function of the volatility matrix. To approximate the integral, we simply use a Riemann sum based on local estimators of the pointwise volatility. We show that although the accuracy of the pointwise estimation is at most $Δ_n^{1/4}$, this procedure reaches the parametric rate $Δ_n^{1/2}$, as it is usually the case in integrated functionals estimation. After a suitable bias correction, we obtain an unbiased central limit theorem for our estimator and show that it is asymptotically efficient within some classes of sub models.

description: We present the constraints on the Quintessence scalar field model from the observational data of the variation of the fine structure constant obtained from Keck and VLT telescopes. Within the theoretical frame proposed by Bekenstein, the constraints on the parameters of the Quintessence scalar field model are obtained. By the consideration of the prior of $Ω_{m0}$ as WMAP 7 suggests, we obtain various results of the different samples. Based on these results, we also calculate the probability density function of the coupling constant $ζ$. The best-fit values show a consistent relationship between $ζ$ and the different experimental results. In our work, we test two different potential models, namely, the inverse power law potential and the exponential potential. The results show that both the large value of the parameters in the potential and the strong coupling can cause the variation of fine structure constant.

description: Flash sintering arouses the interest since high-density ceramics can be obtained at shorter dwell times and lower temperatures than conventional sintering. In this study, the cubic garnet Li6.25Al0.25La3Zr2O12 (Al-LLZO) was successfully synthesised by the solid-state method. The powders were uniaxially pressed and were subjected to flash sintering at 850°C in a tube furnace under a DC bias using various current densities. It is evidenced that control of the flash electric current is a crucial factor for densification of Al-LLZO. The sample sintered in 50 V cm−1 and 200 mA mm−2 showed a cubic LLZO, 94 ± 0.4% relative density, 0.37 mS cm−1 total ionic conductivity and 0.32 eV activation energy. In addition, it was demonstrated that increasing the current density had a considerable impact on the relative density. This outstanding ionic conductivity might be due to the lower lithium loss and higher density as a result of flash sintering method applied.

description: In atomic physics, adiabatic evolution is often used to achieve a robust and efficient population transfer. Many adiabatic schemes have also been implemented in optical waveguide structures. Recently there has been increasing interests in the influence of decay and absorption, and their engineering applications. Here it is shown that even a small decay can significantly influence the dynamical behaviour of a system, above and beyond a mere change of the overall norm. In particular, a small decay can lead to a breakdown of adiabatic transfer schemes, even when both the spectrum and the eigenfunctions are only sightly modified. This is demonstrated for the generalization of a STIRAP scheme that has recently been implemented in optical waveguide structures. Here the question how an additional absorption in either the initial or the target waveguide influences the transfer property of the scheme is addressed. It is found that the scheme breaks down for small values of the absorption at a relatively sharp threshold, which can be estimated by simple analytical arguments.

description: In nature, organisms are faced with constant nutritional options which fuel key life-history traits. Studies have shown that species can actively make nutritional decisions based on internal and external cues. Metabolism itself is underpinned by complex genomic interactions involving components from both nuclear and mitochondrial genomes. Products from these two genomes must coordinate how nutrients are extracted, used and recycled. Given the complicated nature of metabolism, it is not well understood how nutritional choices are affected by mitonuclear interactions. This is under the rationale that changes in genomic interactions will affect metabolic flux and change physiological requirements. To this end we used a large Drosophila mitonuclear genetic panel, comprising 9 isogenic nuclear genomes coupled to 9 mitochondrial haplotypes, giving a total of 81 different mitonuclear genotypes. We use a capillary-based feeding assay to screen this panel for dietary preference between carbohydrate and protein. We find significant mitonuclear interactions modulating nutritional choices, with these epistatic interaction also being dependent on sex. Our findings support the notion that complex genomic interactions can place a constraint on metabolic flux. This work gives us deeper insights on how key metabolic interactions can have large implications on behaviour.

We prove that some conditional information inequalities cannot be extended to any unconditional linear inequalities. Some of these conditional inequalities hold for almost entropic points, while others do not. We also discuss some counterparts of conditional information inequalities for Kolmogorov complexity.

Year: 2012

description: Motivated by a host of recent applications requiring some amount of redundancy, frames are becoming a standard tool in the signal processing toolbox. In this paper, we study a specific class of frames, known as discrete Fourier transform (DFT) codes, and introduce the notion of systematic frames for this class. This is encouraged by a new application of frames, namely, distributed source coding that uses DFT codes for compression. Studying their extreme eigenvalues, we show that, unlike DFT frames, systematic DFT frames are not necessarily tight. Then, we come up with conditions for which these frames can be tight. In either case, the best and worst systematic frames are established in the minimum mean-squared reconstruction error sense. Eigenvalues of DFT frames and their subframes play a pivotal role in this work. Particularly, we derive some bounds on the extreme eigenvalues DFT subframes which are used to prove most of the results; these bounds are valuable independently.
Bulk elastic fingering instability in Hele-Shaw cells

description: We demonstrate experimentally the existence of a purely elastic fingering instability which arises when air penetrates into an elastomer confined in a Hele-Shaw cell. Fingers appear sequentially and propagate within the bulk of the material as soon as a critical strain, independent of the elastic modulus, is exceeded. Their width depends non-linearly on the distance between the confining glass plates. A key element in the driving force of the instability is the adhesion of layers of gels to the plates, which results in a considerable expense of elastic energy during the growth of the air bubble.

description: Causal inference is a rapidly growing field of statistics that applies logical reasoning to statistical inference to estimate causal relationships. Spatial data poses several problems in causal inference – namely, spatial confounding and interference – that require different strategies when designing causal models. In order to obtain valid inferences, existing nonspatial causal models must adjust for such spatial problems. Given the blossoming literature on spatial causal inference, this research analyzes the usage of spatial causal models under a priori knowledge and a priori ignorance of the spatial structure of data. We synthesize existing research directions in noncausal spatial modelling and causal nonspatial modelling by assessing the performance of 28 spatial causal models across 16 spatial data scenarios. We used ordinary least squares (OLS) models, conditional autoregressive (CAR) models, and jointly CAR models for outcome and treatment variables as the basis for the tested models, equipping them with a variety of spatial causal adjustments. We compare our results to principles of noncausal spatial modelling and investigate their implications for spatial causal modelling. Specifically, we show that noncausal spatial modelling guidance holds in causal spatial modelling workflows and demonstrate how researchers can leverage noncausal theory to great effect. In parallel, we introduce the spycause Python package of spatial causal models and data simulators to facilitate the widespread use of these models and to enable reproduction and extension of our work.

description: We explore the implications of a 126 GeV Higgs boson indicated by the recent LHC results for two-Higgs doublet model (2HDM). Identifying the 126 GeV Higgs boson as either the lighter or heavier of CP even neutral Higgs bosons in 2HDM, we examine how the masses of Higgs fields and mixing parameters can be constrained by the theoretical conditions and experimental constraints. The theoretical conditions taken into account are the vacuum stability, perturbativity and unitarity required to be satisfied up to a cut-off scale. We also show how bounds on the masses of Higgs bosons and mixing parameters depend on the cut-off scale. In addition, we investigate whether the allowed regions of parameter space can accommodate particularly the enhanced di-photon signals, ZZ* and WW* decay modes of the Higgs boson, and examine the prediction of the signal strength of Zγ decay mode for the allowed regions of the parameter space.

description: We describe a new method for finding analytic solutions to some initial-boundary problems for partial differential equations with constant coefficients. The method is based on expanding the denominator of the Laplace transformed Green's function of the problem into a convergent geometric series. If the denominator is a linear combination of exponents with real powers one obtains a closed form solution as a sum with finite but time dependent number of terms. We call it a d'Alembert sum. This representation is computationally most effective for small evolution times, but it remains valid even when the system of eigenmodes is incomplete and the eigenmode expansion is unavailable. Moreover, it simplifies in such cases. In vibratory problems d'Alembert sums represent superpositions of original and partially reflected traveling waves. They generalize the d'Alembert type formulas for the wave equation, and reduce to them when original waves can undergo only finitely many reflections in the entire course of evolution. The method is applied to vibrations of a bar with dampers at each end and at some internal point. The results are illustrated by computer simulations and comparisons to modal and FEM solutions.

For each such metric, we look at the first eigenvalue λ_1 of the Laplacian associated with it. We show that λ_1 can be made arbitrarily large, when we vary the metric. This generalizes previous results of Polterovich, and of Mangoubi.

description: We extend the work of Narasimhan and Bilmes [30] for minimizing set functions representable as a difference between submodular functions. Similar to [30], our new algorithms are guaranteed to monotonically reduce the objective function at every step. We empirically and theoretically show that the per-iteration cost of our algorithms is much less than [30], and our algorithms can be used to efficiently minimize a difference between submodular functions under various combinatorial constraints, a problem not previously addressed. We provide computational bounds and a hardness result on the mul- tiplicative inapproximability of minimizing the difference between submodular functions. We show, however, that it is possible to give worst-case additive bounds by providing a polynomial time computable lower-bound on the minima. Finally we show how a number of machine learning problems can be modeled as minimizing the difference between submodular functions. We experimentally show the validity of our algorithms by testing them on the problem of feature selection with submodular cost features.

description: To test whether the coil, or specifically the vertical axis of the coil, was producing RF noise that may differ between the treatments in our experiment we used a single wrapped Helmholtz coil (the same model used in the experiments in Latvia) and a passive antenna placed either vertically (Figure S4) or horizontally (Figure S5) connected to a spectrum analyser (MP700022 EU-UK). The coil was either unpowered (black trace), turned on with the power settings matched to those used in the 120 degree shift positive inclination treatment used in our experiment (red trace), or turned on with the power matched to the negative inclination treatment. The spectrum analyser was set to record ‘Max Hold’ – collected the maximum power readings at all frequency bands during a 30 second window. Whist there was clearly the presence of background RF signals (e.g. the 100 MHz spike can be attributed to FM radio signals), these were present at the same level in each of the recordings we took, with no differences that may suggest RF noise produced by the coil may have caused the differences that we observed in our treatments.

description: Using the (nearly) Ricci-flat Swiss-Cheese metric of [1], in the context of a mobile space-time filling D3-brane restricted to a nearly special Lagrangian sub-manifold (in the large volume limit, the pull-back of the Kaehler form close to zero and the real part of the pull-back of e^{-i theta},theta=pi/2 times the nowhere-vanishing holomorphic three-form providing the volume form on the three-cycle) of the "big" divisor with (fluxed stacks of) space-time filling D7-branes also wrapping the "big" divisor (corresponding to a local minimum), we provide an explicit identification of the electron and the u-quark, as well as their SU(2)_L-singlet cousins, with fermionic super-partners of four Wilson line moduli; their superpartners turn out to be very heavy, the Higgsino-mass parameter turns out to be large, one obtains one light (with a mass of 125 GeV) and one heavy Higgs and the gluino is long lived (from a collider point of view) providing a possible realization of "mu-Split Supersymmetry". By explicitly calculating the lifetimes of decays of the co-NLSPs - the first generation squark/slepton and a neutralino - to the LSP - the gravitino - as well as gravitino decays, we verify that BBN constraints relevant to the former as well as the requirement of the latter to be (more than) the age of the universe, are satisfied. For the purpose of calculation of the gravitino relic abundance in terms of the neutralino/slepton relic abundance, we evaluate the latter by evaluating the netralino/slepton (co-)annihilation cross sections and hence show that the former satisfies the requirement for a Dark Matter candidate.

description: Recently, generalizations of fractional quantum Hall (FQH) states known as fractional quantum anomalous Hall or, equivalently, fractional Chern insulators states have been realized in lattice models. Ideal wavefunctions such as the Laughlin wavefunction, as well as the corresponding trial Hamiltonians for which the former are exact ground states, have been vital to characterizing FQH phases. The Wannier function representation of fractional Chern insulators proposed in [X.-L. Qi, Phys. Rev. Lett., 126803] defines an approach to generalize these concepts to fractional Chern insulators. In this paper, we apply the Wannier function representation to develop a systematic pseudopotential formalism for fractional Chern insulators. The family of pseudopotential Hamiltonians is defined as the set of projectors onto asymptotic relative angular momentum components which forms an orthogonal basis of two-body Hamiltonians with magnetic translation symmetry. This approach serves both as an expansion tool for interactions and as a definition of positive semidefinite Hamiltonians for which the ideal fractional Chern insulator wavefunctions are exact nullspace modes. We compare the short-range two-body pseudopotential expansion of various fractional Chern insulator models at one-third filling in phase regimes where a Laughlin-type ground state is expected to be realized. We also discuss the effect of inhomogeneous Berry curvature which leads to components of the Hamiltonian that cannot be expanded into pseudopotentials, and elaborate on their role in determining low energy theories for fractional Chern insulators. Finally, we generalize our Chern pseudopotential approach to interactions involving more than two bodies with the goal of facilitating the identification of non-Abelian fractional Chern insulators.

title: Children's quest for love and professional child protection work : the case of Norway
Creators: name: Basberg Neumann, Cecilie
Publisher: name: Strathprints - University of Strathclyde

description: Central actors in the child protection field in Norway argue that children in public care should not only receive care and support, but also love. It is hard to disagree that children need love. However, there is reason to question the situation that may arise if children's need for love is translated into requirements that must be safeguarded and handled by child protection workers in the child protection services. In this article, I analyse this 'requirement of love' both with regard to the increased focus on children's rights in discussions on children's life conditions and to the history of the professionalisation of social work; having the gendered features of social work and its partial professionalisation in mind. Due to the challenges this requirement represents, there may be good reasons to revisit the debates on care and care work among feminists who have theorised care as work within professional contexts. I try to show how the field of social work and child protection may utilise the critical potential in care feminist thinking by connecting it to their own emphasis on emotional awareness and knowledge of self as a prerequisite for professional child protection work.
Discrete SL2 Connections and Self-Adjoint Difference Operators on the Triangulated 2-manifold

description: Discretization Program of the famous Completely Integrable Systems and associated Linear Operators was developed in 1990s. In particular, specific properties of the second order difference operators on the triangulated manifolds and equilateral triangle lattices were studied in the works of S.Novikov and I.Dynnikov since 1996. They involve factorization of operators, the so-called Laplace Transformations, new discretization of Complex Analysis and new discretization of $GL_n$ connections on the triangulated $n$-manifolds. The general theory of the new type discrete $GL_n$ connections was developed. However, the special case of $SL_n$-connections (and unimodular $SL_n^{\pm}$ connections such that $\det A=\pm 1$) was not selected properly. As we prove in this work, it plays fundamental role (similar to magnetic field in the continuous case) in the theory of self-adjoint discrete Schrodinger operators for the equilateral triangle lattice in $\RR^2$. In Appendix~1 we present a complete characterization of rank 1 unimodular $SL_n^{\pm}$ connections. Therefore we correct a mistake made in the previous versions of our paper (we wrongly claimed that for $n>2$ every unimodular $SL_n^{\pm}$ Connection is equivalent to the standard Canonical Connection). Using communications of Korepanov we completely clarify connection of classical theory of electric chains and star-triangle with discrete Laplace transformation on the triangle lattices

(Figs. 45–53; Figs. 74–77) Type materials: China: holotype: m#, Lijiang (26° 53’02” N, 100° 13’32” E), Yunnan Prov., 13 November 1999, 2300 m, coll. Daozheng Qin; paratypes: 7 m #, same data as holotype. (all in NWAFU). Length: m# 2.9 mm. Ground color of body yellowish-green (Fig. 77). Crown with yellow patch on each side of coronal suture (Fig. 74). Eyes black. Pronotum with yellow irregular patches on anterior margin of pronotum and under eyes. Forewing and hindwing semitransparent. Abdomen yellowish-green. Legs light yellow to green (Fig. 76). Ventral abdominal apodemes short, only reaching segment 3, parallel-sided (Fig. 47). Pygofer in lateral view with posterior margin broadly rounded; 13–14 stout setae in group along posterior margin, few slim setae near stout setae group (Fig. 45); pygofer appendage following posterior margin of pygofer, not extended beyond pygofer, broadly bifurcated with dorsal branch much longer than ventral branch (Fig. 46). Anal tube broad at base, tapering and slightly sinuate toward apex (Fig. 49). Subgenital plate in lateral view, curved gradually caudodorsad apically, not expanded apically; with numerous macrosetae and fine setae somewhat irregularly arranged; dorsolateral margin group A with 5 long stout setae subbasally and group B with 18–19 short microsetae on apical half (Fig. 53). Paramere with 5 teeth on dentifer, 4–5 setae subapically, apex nearly straight in lateral view, curved laterad in ventral view (Fig. 52). Connective broader than long, posterior margin medially emarginate (Fig. 48). Aedeagus in lateral view with preatrium long, aedeagal shaft curved dorsally, narrowing to apex (Figs. 50, 51).

description: Mike Stowell was a Bristol physicist turned metallurgist who led the development of practical aluminium-based superplastic alloys by showing how to retain grains small enough, at temperatures high enough, to allow almost unlimited shape changes in forming operations. He can be regarded as the father of SUPRAL alloys, as these are now called. At the Tube Investment laboratory in Hinxton Hall, Essex, he led teams that made effective use of the novel electron-optical equipment invented there to solve numerous fascinating problems of technical importance, among them the sequence of growth by evaporation of thin metallic films and the mechanisms controlling the precipitation of graphite in cast iron. He was dedicated to science at the heart of industrial metallurgy, so that when the laboratory closed, rather than retire, he became research director at Alcan, interacting with a laboratory in Italy as well as managing disparate laboratories in England and Canada to develop coatings for the electrodes used in aluminium production. He was a founder member of what we now know as the ‘Cambridge Phenomenon’, the close interaction between innovative, high-tech industry and the university. In connection with these activities, he made long-lasting fundamental contributions to the understanding of precipitation both of two-dimensional islands in the growth of thin films and in three dimensions in the bulk solid state.

description: In this work, we consider a network of cosmic strings to explain possible deviation from ΛCDM behaviour. We use different observational data to constrain the model and show that a small but non zero contribution from the string network is allowed by the observational data which can result in a reasonable departure from ΛCDM evolution. But by calculating the Bayesian Evidence, we show that the present data still strongly favour the concordance ΛCDM model irrespective of the choice of the prior.
