description: We studied freshwater gastropod fauna in a heavily urbanized region in tropical India, across a range of habitat types. A total of 16 species were found from a two-year survey, which is a decline of 27% compared to studies completed in the 1970s. Planorbidae was the most species rich family in the collection, with five species. Racesina luteola (Lamarck, 1822) was the most commonly occurring species in the collection. Three non-native species, including Pomacea diffusa (Blume, 1957), are also reported. Habitat type influenced species occurrences, although lentic and lotic habitats were largely similar in their fauna. Many species reported previously were missing from the current survey, along with an increased incidence of non-native species which were absent from earlier reports. This decline in species richness, particularly of native species, alongside an increased incidence and spread of non-native species in the region, highlights the impact of urbanization on the freshwater gastropod community.

description: In the coming years, experiments underway will increase the sensitivity to charged lepton flavor violation by four orders of magnitude. These experiments will stringently probe weak scale physics. I review the status of global symmetries in the standard model and present several well-motivated models that predict observable lepton flavor violation. Finally, I describe what we might learn from future experimental results, whether positive or null.

The predictions obtained for $B \to πD^*_2, ρD_2^*$ are a factor of $3\sim 5$ below present experimental upper limits. Interesting patterns are obtained for ratios of B decays involving mesons with different spin excitations and their relevance for additional tests of forms factor models are briefly discussed.

description: We show that micron-scale two-dimensional (2D) honeycomb microwells can significantly improve the stability of blue phase liquid crystals (BPLCs). Polymeric microwells made by direct laser writing improve various features of the blue phase (BP) including a dramatic extension of stable temperature range and a large increase both in reflectivity and thermal stability of the reflective peak wavelength. These results are mainly attributed to the omni-directional anchoring of the isotropically oriented BP molecules at the polymer walls of the hexagonal microwells and at the top and bottom substrates. This leads to an omni-directional stabilization of the entire BPLC system. This study not only provides a novel insight into the mechanism for the BP formation in the 2D microwell but also points to an improved route to stabilize BP using 2D microwell arrays.

description: Automatic reading texts in scenes has attracted increasing interest in recent years as texts often carry rich semantic information that is useful for scene understanding. In this paper, we propose a novel scene text proposal technique aiming for accurate reading texts in scenes. Inspired by the pooling layer in the deep neural network architecture, a pooling based scene text proposal technique is developed. A novel score function is designed which exploits the histogram of oriented gradients and is capable of ranking the proposals according to their probabilities of being text. An end-to-end scene text reading system has also been developed by incorporating the proposed scene text proposal technique where false alarms elimination and words recognition are performed simultaneously. Extensive experiments over several public datasets show that the proposed technique can handle multi-orientation and multi-language scene texts and obtains outstanding proposal performance. The developed end-to-end systems also achieve very competitive scene text spotting and reading performance.

description: A Wigner crystal structure of the electronic ground state is induced by strong Coulomb interactions at low temperature in clean or disordered two-dimensional (2d) samples. For fermions on a mesoscopic disordered 2d lattice, being closed to a torus, we study the persistent current in the regime of strong interaction at zero temperature. We perform a perturbation expansion starting from the Wigner crystal limit which yields power laws for the dependence of the persistent current on the interaction strength. The sign of the persistent current in the strong interaction limit is independent of the disorder realization and strength. It depends only on the electro-statically determined configuration of the particles in the Wigner crystal.

description: By solving the 5-body Faddeev-Yakubovsky equations in configuration space with realistic nuclear Hamiltonians we have studied the resonant states of $^5$H isotope. Two different methods, allowing to bypass the exponentially diverging boundary conditions, have been employed providing consistent results. The existence of $^5$H broad J$^π$=1/2$^+$,3/2$^+$,5/2$^+$ states as S-matrix poles has been confirmed and compared with the, also calculated, resonant states in $^4$H isotope. We have established that the positions of these resonances only mildly depend on the nuclear interaction model.

description: For the two dimensional kinetic Ising model at finite temperature, the local mean magnetisation $M_t=t^{-1}\int_{0}^tσ(t')\d t'$, simply related to the fraction of time spent by a given spin in the positive direction, has a limiting distribution, singular at $\pm m_0(T)$, the Onsager spontaneous magnetization. The exponent of this singularity defines the persistence exponent $θ$. We also study first passage exponents associated to persistent large deviations of $M_t$, and their temperature dependence.

A Maximum Likelihood-Based Minimum Mean Square Error Separation and Estimation of Stationary Gaussian Sources from Noisy Mixtures
Creators: name: Weiss, Amir

Publisher: name: arXiv
Year: 2018
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: In the context of Independent Component Analysis (ICA), noisy mixtures pose a dilemma regarding the desired objective. On one hand, a "maximally separating" solution, providing the minimal attainable Interference-to-Source-Ratio (ISR), would often suffer from significant residual noise. On the other hand, optimal Minimum Mean Square Error (MMSE) estimation would yield estimates which are the "closest possible" to the true sources, often at the cost of compromised ISR. In this work, we consider noisy mixtures of temporally-diverse stationary Gaussian sources in a semi-blind scenario, which conveniently lends itself to either one of these objectives. We begin by deriving the ML Estimates (MLEs) of the unknown (deterministic) parameters of the model: the mixing matrix and the (possibly different) noise variances in each sensor. We derive the likelihood equations for these parameters, as well as the corresponding Cramér-Rao lower bound, and propose an iterative solution for obtaining the MLEs. Based on these MLEs, the asymptotically-optimal "maximally separating" solution can be readily obtained. However, we also present the ML-based MMSE estimate of the sources, alongside a frequency-domain-based computationally efficient scheme, exploiting their stationarity. We show that this estimate is asymptotically optimal and attains the (oracle) MMSE lower bound. Furthermore, for non-Gaussian signals, we show that this estimate serves as a Quasi ML (QML)-based Linear MMSE (LMMSE) estimate, and attains the (oracle) LMMSE lower bound asymptotically. Empirical results of three simulation experiments are presented, corroborating our analytical derivations.

description: In this article we take a small step in answering the famous question “Can one hear the shape of a drum?” Recently, Grieser and Maronna have shown that if the drum is shaped like a triangle, the answer is yes.
In this article we investigate this question for trapezoid drums. We define a subset of trapezia and prove that for drums of this shape the answer to the question is also yes. To do this, we need to investigate periodic orbits in a triangle. In particular we prove a lower limit on the length of families of periodic orbits.

description: Observations of the debris disk around the solar-like star HD 107146 reveal the disk (nearly) transiting an extended background galaxy. By using out-of-transit observations to model the galaxy, we show it to be smooth and well modelable. When subtracting this model from the edge-of-transit observation, attenuation by dust of the debris disk in the line-of-sight can be seen. From this we calculate the column density of the dust. The results of this new way of detecting debris dust agree with previous work, however at increasing distance from the star we find an increasing column density, suggesting dust segregation.

description: We study a model-independent parameterization of the vector pion form factor that arises from the constraints of analyticity and unitarity. Our description should be suitable up to sqrt(s) ~ 1.2 GeV and allows a model-independent determination of the mass of the rho(770) resonance, M(rho) = (775.1 +- 0.5) MeV. We analyse the experimental data on tau(-) -> pion(-) pion(0) neutrino(tau), in this framework, and its consequences on the low-energy observables worked out by chiral perturbation theory. An evaluation of the two-pion contribution to the anomalous magnetic moment of the muon, a_muon, and to the fine structure constant, alpha(M(Z)^2), is also performed.

description: Bismuth-based photocatalytic technology has been a promising way to degrade contaminants in the aqueous system. In this work, a direct Z-scheme BiOCl/Bi3NbO7 heterojunction with a different molar ratio of Bi and Nb elements was fabricated through a facile in situ growth method. The structural and photoelectric characteristics of these as-prepared samples were investigated by SEM, XPS, TEM, XRD, BET, UV-vis DRS, PL, EIS and TPC. The photocatalytic activity was evaluated by the degradation of RhB, and its mechanism was analyzed by the active species trapping experiments and DFT calculation. The results showed that compared with other as-prepared samples, BN-4 had the highest activity for RhB degradation with the value of the rate constant (k) being 0.01664 min−1. The reason that might be those different molar ratios of Bi and Nb elements in BiOCl/Bi3NbO7 heterojunction would impact the interface structure. And an appropriate molar ratio of that could bring a lower interface resistance that enhances the photocatalytic activity. The •OH and •O2− were the main active substances during the RhB photocatalytic process, and a reasonable degradation pathway was proposed.

description: In Mediterranean Europe, both intensification and abandonment of traditional cultural practices represent main drivers for the loss of natural and semi-natural elements in agricultural settings. Once common in rural landscapes, these habitats have to be conserved or restored to ensure resilience and resistance of agroecosystems against biodiversity loss and socio-ecological changes. In particular, linear landscape elements (LE) fall among the high-biodiversity landscape features that require to be increased in agricultural lands to facilitate species mobility and provide a wide range of ecosystem services. However, within the framework of environmental accounting procedures, there is still a need for a thorough methodology to assess conditions of LE and, subsequently, of the hosting agroecosystems. The present research is therefore aimed at (i) proposing a method for a thorough assessment of LE conditions, with a special focus on biodiversity support capacity, (ii) investigating the potential effect of extrinsic determinants on LE conditions, such as contiguity to protected habitats and governance framework, and (iii) identifying useful parameters to guide LE ecological restoration actions. Based on different structural, compositional and landscape indicators, the proposed assessment method was tested in eight administrative units of two Mediterranean Europe countries. In the study sites, favorable LE conditions were found to be strongly associated with contiguity to protected habitats, by showing marked structural continuity, dominance of trees, active dynamics, and good quality of the surrounding landscape mosaic. Potential applications of the results have been finally explored in both ecosystem accounting and ecological restoration processes.

We assume the transverse and the longitudinal polarization densities to be equal at a very small scale, as it is suggested by confinement model results. Using a global fit for the longitudinal distributions, we find transverse asymmetries of order of 10^-2 at most, in the accessible kinematic regions.

description: Blockchain is considered one of the most disruptive technologies of our time. Numerous cities around the world are launching blockchain initiatives as part of the overall efforts toward shaping the urban future. However, the infancy stage of the blockchain industry leads to a severe gap between the knowledge we have and the actions urban policy makers are taking. This paper is an effort to narrow this rift. We provide a systematic literature review on concrete blockchain use cases proposed by the research community. At the macro-level, we discuss and organize use cases from 159 selected papers into nine sectors recognized as crucial for sustainable and smart urban future. At the micro-level, we identify a component-based framework and analyze the design and prototypes of blockchain systems studied in a subset of 71 papers. The high-level use case review allows us to illustrate the relationship between them and the four pillars of urban sustainability: social, economic, environmental, and governmental. The system level analysis helps us highlight interesting inconsistencies between well-known blockchain applicability decision rules and the approaches taken by the literature. We also offer two classification methodologies for blockchain use cases and elaborate on how they can be applied to stimulate cross-sector insights in the blockchain knowledge domain.

description: Cultural heritage is the asset of all the peoples of the world. The preservation and inheritance of cultural heritage is conducive to the progress of human civilization. In northwestern China, there is a world heritage site -- Mogao Grottoes -- that has a plenty of mural paintings showing the historical cultures of ancient China. To study these historical cultures, one critical procedure is to date the mural paintings, i.e., determining the era when they were created. Until now, most mural paintings at Mogao Grottoes have been dated by directly referring to the mural texts or historical documents. However, some are still left with creation-era undetermined due to the lack of reference materials. Considering that the drawing style of mural paintings was changing along the history and the drawing style can be learned and quantified through painting data, we formulate the problem of mural-painting dating into a problem of drawing-style classification. In fact, drawing styles can be expressed not only in color or curvature, but also in some unknown forms -- the forms that have not been observed. To this end, besides sophisticated color and shape descriptors, a deep convolution neural network is designed to encode the implicit drawing styles. 3860 mural paintings collected from 194 different grottoes with determined creation-era labels are used to train the classification model and build the dating method. In experiments, the proposed dating method is applied to seven mural paintings which were previously dated with controversies, and the exciting new dating results are approved by the Dunhuang expert.

picks up the sound from different microphones, and applies smart filters once the system has determined which sounds originate from the same source.This problem also becomes topical when developing sensors based on passive sonar, for instance for autonomous aquatic drones who have to develop awareness of ships and other possible obstacles on a busy shipping lane.

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

description: We study the distribution of persistent sites (sites unvisited by particles $A$) in one dimensional $A+A\to\emptyset$ reaction-diffusion model. We define the {\it empty intervals} as the separations between adjacent persistent sites, and study their size distribution $n(k,t)$ as a function of interval length $k$ and time $t$. The decay of persistence is the process of irreversible coalescence of these empty intervals, which we study analytically under the Independent Interval Approximation (IIA). Physical considerations suggest that the asymptotic solution is given by the dynamic scaling form $n(k,t)=s^{-2}f(k/s)$ with the average interval size $s\sim t^{1/2}$. We show under the IIA that the scaling function $f(x)\sim x^{-τ}$ as $x\to 0$ and decays exponentially at large $x$. The exponent $τ$ is related to the persistence exponent $θ$ through the scaling relation $τ=2(1-θ)$. We compare these predictions with the results of numerical simulations. We determine the two-point correlation function $C(r,t)$ under the IIA. We find that for $r\ll s$, $C(r,t)\sim r^{-α}$ where $α=2-τ$, in agreement with our earlier numerical results.

description: The genetic and/or antigenic differences between street rabies virus (RABV) and vaccine strains could potentially affect effectiveness of rabies vaccines. As such, it is important to continue monitoring the glycoprotein (G) of the street isolates. All RABVG sequences in public database were retrieved and analysed. Using a pseudovirus system, we investigated 99 naturally occurring mutants for their reactivities to well-characterized neutralizing monoclonal antibodies (mAbs) and vaccine-induced antisera. A divergence in G sequences was found between vaccine strains and recent street isolates, with mutants demonstrating resistance to neutralizing mAbs and vaccine-induced antibodies. Moreover, antigenic variants were observed in a wide range of animal hosts and geographic locations, with most of them emerging since 2010. As the number of antigenic variants has increased in recent years, close monitoring on street isolates should be strengthened.

Wigner crystal model of counterion induced bundle formation of rod-like polyelectrolytes

description: A simple electrostatic theory of condensation of rod-like polyelectrolytes under influence of polyvalent ions is proposed. It is based on the idea that Manning condensation of ions results in formation of the Wigner crystal on a background of a bundle of rods. It is shown that, depending on a single dimensionless parameter, this can be the densely packed three-dimensional Wigner crystal or the two-dimensional crystal on the rod surfaces. For DNA the location of charge on the spiral results in a model of the one-dimensional Wigner crystal. It is also argued that the Wigner crystal idea can be applied to self-assembly of other polyelectrolytes, for example, colloids and DNA-lipid complexes.

description: We summarize the key results of a recent global analysis of inclusive single-charged-hadron production in high-energy colliding-beam experiments. In the framework of the parton model of quantum chromodynamics at next-to-leading order (NLO), fragmentation functions (FFs) for charged pions, charged kaons, and (anti) protons are extracted from experimental data of e^+e^- annihilation at the Z-boson resonance and at centre-of-mass energy root(s) = 29 GeV. This fit also yields a new NLO value for the strong-coupling constant, namely alpha_s^(5)(M_Z) = 0.1170 +- 0.0073. The scaling violations encoded in the FFs through the Altarelli-Parisi evolution equations are tested by confronting (e^+e^-)-annihilation data from DESY DORIS, DESY PETRA, and CERN LEP2 with NLO predictions based on these FFs. Comparisons of p p-bar data from CERN S p p-bar S and the Fermilab Tevatron, gamma p data from DESY HERA, and gamma gamma data from LEP2 with the corresponding NLO predictions allow us to test the universality of the FFs predicted by the factorization theorem.

description: Charge transport layers (CTLs) are key components of diffusion controlled perovskite solar cells, however, they can induce additional non-radiative recombination pathways which limit the open circuit voltage (V_OC) of the cell. In order to realize the full thermodynamic potential of the perovskite absorber, both the electron and hole transport layer (ETL/HTL) need to be as selective as possible. By measuring the quasi-Fermi level splitting (QFLS) of perovskite/CTL heterojunctions, we quantify the non-radiative interfacial recombination current for a wide range of commonly used CTLs, including various hole-transporting polymers, spiro-OMeTAD, metal oxides and fullerenes. We find that all studied CTLs limit the V_OC by inducing an additional non-radiative recombination current that is significantly larger than the loss in the neat perovskite and that the least-selective interface sets the upper limit for the V_OC of the device. The results also show that the V_OC equals the internal QFLS in the absorber layer of (pin, nip) cells with selective CTLs and power conversion efficiencies of up to 21.4%. However, in case of less selective CTLs, the V_OC is substantially lower than the QFLS which indicates additional losses at the contacts and/or interfaces. The findings are corroborated by rigorous device simulations which outline several important considerations to maximize the V_OC. This work shows that the real challenge to supress non-radiative recombination losses in perovskite cells on their way to the radiative limit lies in the suppression of carrier recombination at the perovskite/CTL interfaces.

title: The Interdependence of Economic Growth, Human Development and Political Institutions
Creators: name: Krantz, Sebastian
Publisher: name: Student Undergraduate Research E-journal!
Year: 2017

description: The causal links between growth, human development and institutions
are central to understanding the long-run development process.
The turn of the millennium has seen influential research in development
economics attempting to uncover some of these links, but a
focus on root-causes of growth has limited its insights in both scope
and method. This paper provides a fresh analysis of the interdependence
of growth, human development and institutions using a general
equilibrium framework. The framework is tested using 4 different
cross-sectional and panel-data specifications including data
from 1820>. Findings implicate that both growth and human development,
but also human development and institutional progress
strongly depend on each other in the long run. The results imply
the existence of significant general-equilibrium effects shaping the
long-run trajectories of countries. These mechanisms defy overly
deterministic views of development, and invite careful further study.

description: We extend classical density theorems of Borel and Dani--Shalom on lattices in semisimple, respectively solvable algebraic groups over local fields to approximate lattices. Our proofs are based on the observation that Zariski closures of approximate subgroups are close to algebraic subgroups. Our main tools are stationary joinings between the hull dynamical systems of discrete approximate subgroups and their Zariski closures.

title: Traffic Management under Boundedly Rational User Equilibrium
Creators: name: Spruijtenburg, Dawn
Publisher: name: Student Undergraduate Research E-journal!
Year: 2017

description: We consider the static traffic assignment model in which travelers are boundedly rational in their route choice. This assignment introduces uncertainty, since generally multiple Boundedly Rational User Equilibrium (BRUE) solutions exist. In this paper, we propose a day-to-day toll strategy that steers the network from an observed BRUE to a desired BRUE. We prove that the stationary state of this toll strategy is the desired flow, and we show by example that the strategy can achieve any flow.

Mechanisms of Granular Spontaneous Stratification and Segregation in Two-Dimensional Silos

description: Spontaneous stratification of granular mixtures has been reported by Makse et al. [Nature 386, 379 (1997)] when a mixture of grains differing in size and shape is poured in a quasi-two-dimensional heap. We study this phenomenon using two different approaches. First, we introduce a cellular automaton model that illustrates clearly the physical mechanism; the model displays stratification whenever the large grains are rougher than the small grains, in agreement with the experiments. Moreover, the dynamics are close to those of the experiments, where the layers are built through a ``kink'' at which the rolling grains are stopped. Second, we develop a continuum approach, based on a recently introduced set of coupled equations for surface flows of granular mixtures that allows us to make quantitative predictions for relevant quantities. We study the continuum model in two limit regimes: the large flux or thick flow regime, where the percolation effect (i.e., segregation of the rolling grains in the flow) is important, and the small flux or thin flow regime, where all the rolling grains are in contact with the surface of the sandpile. We find that the wavelength of the layers behaves linearly with the flux of grains. We obtain analytical predictions for the shape of the kink giving rise to stratification as well as the profile of the rolling and static species when segregation of the species is observed.

description: This research aims to identify the necessary conditions and reforms for Russia to transition to an innovative development path and attain a socio-economic level comparable to that of developed countries. The research goal is achieved by analyzing the key macroeconomic drivers of scientific and technological development and evaluating public policy, budget priorities, and ongoing reforms from the past 30 years. The research also investigates the “five crises of human capital” and the loss of more than 57% of Russia’s scientific and technological potential. Using correlation and comparative analysis methods, the research analyzes the relationship between economic growth rates, high-tech production, and human capital. The research establishes that 96% of the dynamics of GDP growth are attributed to investments in technology transfer, the creation of comfortable conditions for attracting and retaining scientific and technological personnel in real sectors of the economy, and not investments in the “knowledge economy.” Moreover, the research emphasizes the possibility of a sixth “human capital crisis” and suggests policy and legislative changes necessary for innovative development comparable to developed countries. The author presents an insightful forecast for the necessary scientific and engineering professionals needed to achieve exponential GDP growth until 2040. Additionally, the author emphasizes the importance of policy and legislative changes toward innovative development comparable to developed nations.

description: Mobility researchers acknowledge the multifaceted nature of individuals' trans-portation choices, influenced by personal attitudes, social norms, and transport infrastructure. However, the complexity of these factors often leads to incon-sistent findings in existing methodologies. Given the significant environmental impact of motorized private transportation, understanding the mechanisms of travel mode choice is imperative for fostering sustainable mobility behaviour. This paper introduces the Extended Model of Mobility Behaviour (xMooBe), a simplified sociological model focusing on transport mode choice. Incorporating concepts from attitude-related and choice models, xMooBe expands subjective expected utility theory by considering contextual factors like car ownership and public transport availability. Empirical testing using a dataset from a mobility survey yields promising results, with the model achieving up to an 80 percent accuracy in explaining behaviour.

Correlations of triggering noise in driven magnetic clusters

description: We show that the temporal fluctuations $ΔH(t)$ of the threshold driving field $H(t)$, which triggers an avalanche in slowly driven disordered ferromagnets with many domains, exhibit long-range correlations in space and time. The probability distribution of the distance between {\it successive} avalanches as well as the distribution of trapping times of domain wall at a given point in space have fractal properties with the universal scaling exponents. We show how these correlations are related to the scaling behavior of Barkhausen avalanches occurring by magnetization reversal. We also suggest a transport equation which takes into account the observed noise correlations.
