description: It has been long known that numerous halide and oxide perovskites can have non-ideal octahedra, showing tilting, rotation, and metal atom displacements. It has also been known that compounds that have at low temperatures a single structural motif ("monomorphous structures") could become disordered at higher temperatures, resulting in non-ideal octahedra as an entropy effect. What is shown here is that in many cubic halide perovskites and some oxides compounds a distribution of different low-symmetry octahedra ("polymorphous networks") emerge already from the minimization of the systems internal energy, i.e., they represent the intrinsic, preferred low temperature pattern of chemical bonding. Thermal disorder effects build up at elevated temperatures on top of such low temperature polymorphous networks. Compared with the monomorphous counterparts, the polymorphous networks have lower predicted total energies (enhanced stability), larger band gaps and dielectric constants now dominated by the ionic part, and agrees much more closely with the observed pair distribution functions. The nominal cubic perovskites (Pm-3m) structure deduced from X-Ray diffraction is actually a macroscopically averaged, high symmetry configuration, which should not be used to model electronic properties, given that the latter reflect a low symmetry local configuration.

description: Plants are attacked by diverse herbivores and respond with manifold defence responses. To study transcriptional and other early regulation events of these plant responses, herbivory is often simulated to standardize the temporal and spatial dynamics that vary tremendously for natural herbivory. Yet, to what extent such simulations of herbivory are able to elicit the same plant response as real herbivory remains largely undetermined. We examined the transcriptional response of a wild model plant to herbivory by lepidopteran larvae and to a commonly used herbivory simulation by applying the larvae's oral secretions to standardized wounds. We designed a microarray for Solanum dulcamara and showed that the transcriptional responses to real and to simulated herbivory by Spodoptera exigua overlapped moderately by about 40%. Interestingly, certain responses were mimicked better than others; 60% of the genes upregulated but not even a quarter of the genes downregulated by herbivory were similarly affected by application of oral secretions to wounds. While the regulation of genes involved in signalling, defence and water stress was mimicked well by the simulated herbivory, most of the genes related to photosynthesis, carbohydrate- and lipid metabolism were exclusively regulated by real herbivory. Thus, wounding and application of oral secretions decently mimics herbivory-induced defence responses but likely not the reallocation of primary metabolites induced by real herbivory.

description: We consider the spin-1/2 antiferromagnetic Heisenberg model on two one-dimensional frustrated lattices, double-tetrahedral chain and octahedral chain, with almost dispersionless (flat) lowest magnon band in a strong magnetic field. Using the localized magnons picture, we construct an effective description of the one-dimensional chains with triangle and square traps within the strong coupling approximation. We perform extensive exact diagonalization and density matrix renormalization group calculations to check the validity of the obtained effective Hamiltonians by comparison with the initial models with special focus on the magnetization and specific heat at high magnetic fields.

description: We count the BPS states of strings in uniform 3-form fluxes, using supersymmetric quantum mechanics derived from the kappa-symmetric action for D-branes. This problem is relevant to the stringy physics of warped compactifications. We work on a type IIB T^6/Z_2 orientifold with imaginary self-dual, quantized, 3-form flux. Ignoring the orientifold projection, the number of short multiplets living on a single string is the square of the units of 3-form flux present on the torus; the orientifold removes roughly half of the multiplets. We review the well-known case of a superparticle on T^2 as an pedagogical example.

description: We prove scattering below the mass-energy threshold for the focusing inhomogeneous nonlinear Schrödinger equation \begin{equation} iu_t + Δu + |x|^{-b}|u|^{p-1}u=0, \end{equation} when $b \geq 0$ and $N > 2$ in the intercritical case $0 < s_c <1$. This work generalizes the results of Farah and Guzmán [9], allowing a broader range of values for the parameters $p$ and $b$. We use a modified version of Dodson-Murphy's approach [6], allowing us to deal with the inhomogeneity. The proof is also valid for the classical nonlinear Schrödinger equation ($b = 0$), extending the work in [6] for radial solutions in all intercritical cases.

BUILDING STRONG DEMOCRATIC INSTITUTIONS: A PANACEA TO GOOD GOVERNACE AND POLICY IMPLEMENTATION IN NIGERIA

Publisher: name: Zenodo
Year: 2012

description: Abstract

Democratic rule in Nigeria since 291h May 1999 has been stable and devoid of military intervention. The stability is predicated on the resolution of the people of Nigeria to institutionalized development and replicate standard global governance. The greatest challenge hindering the growth of democratic values is the issue of political corruption. Corruption has challenged the challenges of democratic governance. Three democratic institutions were looked into in this study. These are, Independent Electoral Commission (INEC), Independent and other Related Crimes Commission (ICPC) and the Economic Financial Crimes Commission (EFCC), in view of their peculiar nature and the role they play in the economy of Nigeria. The study was conducted with the aid of materials from secondary sources. The paper supports institutionalization of the legislature and the need to build and strengthen the nation's democratic institutions and further encourage the implementation of governmental policies for the sustainability of peace and equity. Usually, frequent changes in. the political and social context could alter the configuration of support for policy formulations mid implementation. Successful policy implementation has become synonymous with growth and development of an economy. The current vision 20:2020 of President Goodluck Jonathan keyed into the developmental strife of the present administration if properly harnessed. The paper therefore submits that good governance and democratic principles could be sustained, if these democratic institutions are strengthened in line with the policies establishing them.
Hodge theory and cohomology with compact supports

Year: 1998
Subjects: subject: Differential Geometry (math.DG)

description: This paper constructs a Hodge theory of noncompact topologically tame manifolds $M$. The main result is an isomorphism between the de Rham cohomology with compact supports of $M$ and the kernel of the Hodge--Witten--Bismut Laplacian $\lap_μ$ associated to a measure $dμ$ which has sufficiently rapid growth at infinity on $M$. This follows from the construction of a space of forms associated to $\lap_μ$ which satisfy an ``extension by zero'' property. The ``extension by zero'' property is proved for manifolds with cylindrical ends possessing gaussian growth measures.
Comparative Laboratory Evaluation of Natural Hydraulic Lime Mortars for Conservation

description: Over the past two decades, natural hydraulic lime (NHL) has become a popular binder in restoration mortars used for the conservation of historic masonry buildings in North America. The most obvious advantage of the NHL mortars is a more rapid setting as compared with non-hydraulic hydrated lime (and lime putty) mortars. At the same time, NHL mortars are said to have the favorable attributes of most lime-based formulations, for example, low-to-medium 28-day strength, and relatively high-water vapor transmissivity (WVT). The longer-term performance of NHL mortars, however, is difficult to predict, as they are produced from impure limestones quarried at various geographical locations in Western Europe. As the mineralogy of the source rock varies, so does the chemistry of the individual hydraulic lime. Moreover, the scarcity of manufacturers’ data and of independent laboratory-based literature on NHL mortars is a very significant issue. The concept of pointing mortar as a building component that is sacrificial and “compatible” – as often discussed for NHLs as for other lime mortars--is difficult to translate into conservation practice in the absence of scientific data. Of course, mortar testing data is only one aspect of those issues, as the behavior of the masonry units would also need to be studied on a building-by-building basis, and in a detailed way to understand “compatibility”. The goal of this research is the examination and comparative evaluation of some fundamental properties of NHL mortars. Eleven NHL binders from four different manufacturers were selected for this study, all of them available in the North American market. More than 200 specimens were prepared with a volumetric (1: 2.25) binder- sand ratio, based on a common mix design for restoration mortars used in the field. For comparison purposes, Type O mortars with a volumetric (1 portland cement: 2.5 hydrated lime: 7.9 aggregate) mix ratio were prepared under the same conditions. Experimental programs were created to study three crucial parameters: compressive strength, water vapor transmission, and water absorption by capillary uptake. The testing programs revealed some interesting data, suggesting that the properties of the subject NHL mortars were relatively independent of the classifications of the binders.
Comparative Study of Traditional Jointing Techniques of Vernacular Timber Framings in New England, America and Jiangnan, China and Some Applications Conservation Practice

description: The start point of this comparative study was to understand how vernacular timber houses in New England and Jiangnan in history responded to building tasks with their characteristic framing and jointing techniques. Function of wood joints was taken as the basis for comparison, as it was the fundamental consideration in the design of joints, and quite similar in vernacular buildings from different building cultures. Therefore two buildings - the Horton House and the Yin Yu Tang house - were chosen as the paradigms of traditional vernacular buildings in New England and Jiangnan. Detailed comparisons were made between their framing methods and wood joints, and more importantly, how the joints accomplished their building tasks. After that, the two actual buildings were located in the larger building contexts of the regions they belonged to, to examine the shared characters as well as diversity within each building culture. The basic consideration was still the problem-solving mechanism, and some concepts underlying were discussed.
The comparison study concluded that: the box frame utilizing three-dimensional jointing, the self-supporting triangular roof structure and jointing emphasizing on structural function were the core characters of English timber framing; while structure composed of simple duplication of building components, ingenious joint designs which had more consideration for aesthetics and reinforced the structure only indirectly were essential to timber construction in Jiangnan. This conclusion was then applied to develop a critical thinking about methodologies of wood building conservation, with specific emphasis on practices in China. The conclusions were in two categories: 1. applying some western approaches in Chinese timber framing conservation, such as developing systematic scientific research; 2. revitalizing traditional practices of construction and repairing in China, such as studying past techniques via precise conservation process, identifying and utilizing techniques which are culturally valuable, and training professional craftsmen to recover the glorious beauty as well as physical soundness.

description: Concerns about the quality of care in nursing homes (NHs) have continued to stimulate research and debate over the past several decades. Although substantial improvements in NH care have taken place, serious challenges remain. With enactment of the Patient Protection and Affordable Care Act (PPACA) and recent NH Value Based Purchasing Demonstrations through the Centers for Medicare and Medicaid Services (CMS), there has been increasing policy interest to efficiently reduce potentially avoidable resident adverse outcomes and costs. Organized into three separate studies, this dissertation explores the comparative and cost-effectiveness of improving NH quality outcomes. The significance and current challenges surrounding NH care quality is discussed in the First Chapter. To gain understanding of current infection prevention interventions conducted in NHs, a systematic literature review was conducted and is presented in Chapter Two. The Third Chapter reports on quantitative findings of NH infections as a function of resident quality and tested variations in nurse workforce characteristics. The Fourth Chapter reports on an economic analysis evaluating the implications of retaining a skilled nursing workforce in NHs. Finally, the Fifth Chapter synthesizes the findings from the previous chapters and serves as the concluding chapter of the dissertation.

description: We consider the evolution of small rotational perturbations, with azimuthal symmetry, of the brane-world cosmological models. The equations describing the temporal, radial, and angular dependence of the perturbations are derived by taking into account the effects of both scalar and tensor parts of the dark energy term on the brane. The time decay of the initial rotation is investigated for several types of equation of state of the ultra-high density cosmological matter. For an expanding Universe, rotation always decays in the case of the perfect dragging, for which the angular velocity of the matter on the brane equals the rotation metric tensor. For non-perfect dragging, the behavior of the rotation is strongly equation of state dependent. For some classes of dense matter, like the stiff causal or the Chaplygin gas, the angular velocity of the matter on the brane is an increasing function of time. For other types of the ultra-dense matter, like the Hagedorn fluid, rotation is smoothed out by the expansion of the Universe. Therefore the study of dynamics of rotational perturbations of brane world models, as well as in general relativity, could provide some insights on the physical properties and equation of state of the cosmological fluid filling the very early Universe.

description: In the past decade, deep neural networks (DNNs) came to the fore as the leading machine learning algorithms for a variety of tasks. Their raise was founded on market needs and engineering craftsmanship, the latter based more on trial and error than on theory. While still far behind the application forefront, the theoretical study of DNNs has recently made important advancements in analyzing the highly over-parameterized regime where some exact results have been obtained. Leveraging these ideas and adopting a more physics-like approach, here we construct a versatile field-theory formalism for supervised deep learning, involving renormalization group, Feynman diagrams and replicas. In particular we show that our approach leads to highly accurate predictions of learning curves of truly deep DNNs trained on polynomial regression tasks and that these predictions can be used for efficient hyper-parameter optimization. In addition, they explain how DNNs generalize well despite being highly over-parameterized, this due to an entropic bias to simple functions which, for the case of fully-connected DNNs with data sampled on the hypersphere, are low order polynomials in the input vector. Being a complex interacting system of artificial neurons, we believe that such tools and methodologies borrowed from condensed matter physics would prove essential for obtaining an accurate quantitative understanding of deep learning.

description: Recently, V.Ginzburg introduced the notion of a principal nilpotent pair (= pn-pair) in a semisimple Lie algebra {\frak g}. It is a double counterpart of the notion of a regular nilpotent element. A pair (e_1,e_2) of commuting nilpotent elements is called a pn-pair, if the dimension of their simultaneous centralizer is equal to the rank of {\frak g} and some bi-homogeneity condition is satisfied. Ginzburg proved that many familiar results of the `ordinary' theory have analogues for pn-pairs. The aim of this article is to develop the theory of nilpotent pairs a bit further and to present some applications of it to dual pairs and sheets. It is shown that a large portion of Ginzburg's theory can be extended to the pairs whose simultaneous centraliser is of dimension rk{\frak g}+1. Such pairs are called almost pn-pairs. It is worth noting that the very existence of almost pn-pairs is a purely "double" phenomenon, because the dimension of "ordinary" orbits is always even. We prove that to any principal or almost nilpotent pair one naturally associates a dual pair. Moreover, this dual pair is reductive if and only if e_1 and e_2 can be included in commuting sl_2-triples. We also study sheets containing members of pn-pairs. Some cases are described, where these sheets are smooth and admit a section.

We evaluate the charge distribution of pixels that collect $<10~\rm{e^-}$ for contributions beyond the leakage current that may be attributed to dark matter interactions. Constraints are placed on so-far unexplored parameter space for dark matter masses between 0.6 and 100 MeV$c^{-2}$.

description: Noise pollution has become a worldwide issue, which has a negative effect on human health. The sound reduction index and absorption coefficient of glued laminated bamboo (glubam) and spruce-pine-fir (SPF) were firstly measured in this study by using the impedance tube method. The effect of moisture content on the acoustic performance of these materials was also investigated. Experimental results revealed that for thick-strip glubam and SPF, the higher moisture content, the higher sound reduction index but lower sound absorption coefficient. However, moisture content does not have an obvious effect on acoustic properties of thin-strip glubam. By comparing with other materials, it can be found that glubam and SPF have relatively high normal-incidence transmission loss but low absorption coefficient and noise reduction coefficient. Glubam shows the similar but even better acoustic insulation performance than SPF, which confirms the possibility of using glubam as an alternative of wood materials. Moreover, a finite element model was built up to simulate the measurement of sound transmission loss in an impedance tube. Some parametric studies were then conducted using the finite element model to prove the effectiveness of increasing thickness, using composites and double-layer panels on improving the soundproof performance of materials.

description: Brane-like vertex operators play an important role in a worldsheet formulation of D-branes and M-theory. In this paper we derive the DBI D-brane action from NSR closed string sigma-model with brane-like states. We also show that these operators carry RR charges and define D-brane wavefunctions in a second quantized formalism.

Time-delay cosmographic forecasts with strong lensing and JWST stellar kinematics

description: We present a joint strong lensing and stellar dynamical framework for future time-delay cosmography purposes. Based on a pixelated source reconstruction and the axisymmetric Jeans equations, we are capable of constraining cosmological distances and hence the current expansion rate of the Universe ($H_0$) to the few percent level per lens, when high signal-to-noise integral field unit (IFU) observations from the next generation of telescopes become available. For illustrating the power of this method, we mock up IFU stellar kinematic data of the prominent lens system RXJ1131-1231, given the specifications of the James Webb Space Telescope. Our analysis shows that the time-delay distance ($D_{Δt}$) can be constrained with 3.1% uncertainty at best, if future IFU stellar kinematics are included in the fit and if the set of candidate model parameterisations contains the true lens potential. These constraints would translate to a 3.2% precision measurement on $H_0$ in flat $Λ$CDM cosmology from the single lens RXJ1131-1231, and can be expected to yield an $H_0$ measure with < 2.0% uncertainty, if similar gains in precision can be reached for two additional lens systems. Moreover, the angular diameter distance ($D_\mathrm{d}$) to RXJ1131-1231 can be constrained with 2.4% precision, providing two distance measurements from a single lens system, which is extremely powerful to further constrain the matter density ($Ω_\mathrm{m}$). The measurement accuracy of $D_\mathrm{d}$, however, is highly sensitive to any systematics in the measurement of the stellar kinematics. For both distance measurements, we strongly advise to probe a large set of physically motivated lens potentials in the future, to minimise the systematic errors associated with the lens mass parameterisation.

description: Two finite sets of points in the plane are called mutually avoiding if any straight line passing through two points of anyone of these two sets does not intersect the convex hull of the other set. For any integer n, we construct a set of n points in general position in the plane which contains no pair of mutually avoiding sets of size more than O (n). The given bound is tight up to a constant factor, since Aronov et al. [AEGKKPS] showed a polynomial time algorithm for finding two mutually avoiding sets of size (n) in any set of n points in general position in the plane.

Spacetime structure of the global vortex

description: We analyse the spacetime structure of the global vortex and its maximal analytic extension in an arbitrary number of spacetime dimensions. We find that the vortex compactifies space on the scale of the Hubble expansion of its worldvolume, in a manner reminiscent of that of the domain wall. We calculate the effective volume of this compactification and remark on its relevance to hierarchy resolution with extra dimensions. We also consider strongly gravitating vortices and derive bounds on the existence of a global vortex solution.
