 Note: —This section includes, as defined here, 20 species. According to Govaerts et al. (2013), Ascolepis includes 22 species. Since Ascolepis lineariglumis Lye (1983a: 561) and Ascolepis elata Welwitsch (1869: 79) are both included in the complex of Ascolepis protea Welwitsch (1969: 75) s.l., we chose not to combine them into Cyperus as separate species. Also, Ascolepis menonguensis Meneses (1956: 259), a species only known from its type-collection, is probably an aberrant form of Ascolepis protea. Furthermore, we chose not to combine the various infraspecific names under Ascolepis protea into Cyperus pending confirmation of the taxonomic status of these taxa.

description: Earthquake monitoring is necessary to promptly identify the affected areas, the severity of the events, and, finally, to estimate damages and plan the actions needed for the restoration process. The use of seismic stations to monitor the strength and origin of earthquakes is limited when dealing with remote areas (we cannot have global capillary coverage). Identification and analysis of all affected areas is mandatory to support areas not monitored by traditional stations. Using social media images in crisis management has proven effective in various situations. However, they are still limited by the possibility of using communication infrastructures in case of an earthquake and by the presence of people in the area. Moreover, social media images and messages cannot be used to estimate the actual severity of earthquakes and their characteristics effectively. The employment of satellites to monitor changes around the globe grants the possibility of exploiting instrumentation that is not limited by the visible spectrum, the presence of land infrastructures, and people in the affected areas. In this work, we propose a new dataset composed of images taken from Sentinel-1 and a new series of tasks to help monitor earthquakes from a new detailed view. Coupled with the data, we provide a series of traditional machine learning and deep learning models as baselines to assess the effectiveness of ML-based models in earthquake analysis.

description: The peculiarities of electric current in semiconductors with nonuniform distribution of charge carriers are studied. The semiclassical drift-diffusion equations consisting of the continuity equations and the Poisson equation are solved numerically using Rusanov finite-difference scheme of third order. The different types of boundary conditions are numerically investigated. It is shown that the stability of the Rusanov scheme for the problem considered is achieved with the Neumann type boundary conditions. These conditions correspond to the absence of diffusion through semiconductor surface. Special set of parameters is found under which a very interesting and unusual transient effect of negative current in nonuniform semiconductors appears. Different regimes of negative current are considered for realistic semiconductor materials.

description: In this paper, we present an analytical solution for the Bohr Hamiltonian with the trigonometric Pöschl Teller (P.T) potential in the cases of γ unstable nuclei and γ stable axially symmetric prolate deformed ones with γ = 0. The energy spectra and corresponding wave functions are derived by means of the asymptotic iteration method. In addition, B(E2) transition rates are calculated and compared with experimental data. Overall good agreement is obtained for inter and intra band transitions within ground state and \b{eta} bands. Our numerical results, particularly for transition rates are much closer to experimental ones in comparison with those obtained by Davidson and Kratzer potentials which are widely used in the literature.

description: In recent years a Hopf algebraic structure underlying the process of renormalization in quantum field theory was found. It led to a Birkhoff factorization for (regularized) Hopf algebra characters, i.e. for Feynman rules. In this work we would like to show that this Birkhoff factorization finds its natural formulation in terms of a classical r-matrix, coming from a Rota-Baxter structure underlying the target space of the regularized Hopf algebra characters. Working in the rooted tree Hopf algebra, the simple case of the Hopf subalgebra of ladder trees is treated in detail. The extension to the general case, i.e. the full Hopf algebra of rooted trees or Feynman graphs is briefly outlined.

description: Purpose: Standard of care for various retinal diseases involves recurrent intravitreal injections. This motivates mathematical modelling efforts to identify influential factors for drug residence time, aiming to minimise administration frequency. We sought to describe the vitreal diffusion of therapeutics in nonclinical species used during drug development assessments. In human eyes, we investigated the impact of variability in vitreous cavity size and eccentricity, and in injection location, on drug elimination.
 Methods: Using a first passage time approach, we modelled the transport-controlled distribution of two standard therapeutic protein formats (Fab and IgG) and elimination through anterior and posterior pathways. Detailed anatomical 3D geometries of mouse, rat, rabbit, cynomolgus monkey, and human eyes were constructed using ocular images and biometry datasets. A scaling relationship was derived for comparison with experimental ocular half-lives.
 Results: Model simulations revealed a dependence of residence time on ocular size and injection location. Delivery to the posterior vitreous resulted in increased vitreal half-life and retinal permeation. Interindividual variability in human eyes had a significant influence on residence time (half-life range of 5-7 days), showing a strong correlation to axial length and vitreal volume. Anterior exit was the predominant route of drug elimination. Contribution of the posterior pathway displayed a small (3%) difference between protein formats, but varied between species (10-30%).
 Conclusions: The modelling results suggest that experimental variability in ocular half-life is partially attributed to anatomical differences and injection site location. Simulations further suggest a potential role of the posterior pathway permeability in determining species differences in ocular pharmacokinetics.

description: Using county tax assessor data, this paper estimates the property value impacts of his-toric designation of neighborhoods for Oklahoma County, Oklahoma. Methodological contri-butions of the study include allowing for spatial and temporal variation of hedonic prices and historic district property values along with the use of finely-delineated spatial fixed effects. Neighborhood historic designation is found to be associated with significant relative apprecia-tion of housing values in most districts. Factors appearing to influence the rate of appreciation are the time span of neighborhood historic designation and the area crime rate. The variation in results across historic neighborhoods suggests that policy makers need to take into account the conditions under which historic designation most likely can succeed.

description: Despite the large sums of money spent to ostensibly support rural areas since the 1930s, a framework for assessing U.S. and Canadian rural policy is conspicuously absent, and thus there is little basis for assessing effectiveness of public policy and public expenditures in this area. The purpose of this paper is to propose a framework based on: 1) broad-based policy ob-jectives; 2) a small number of measurable targets that reflect these objectives; and 3) evaluation based on the latest methodological and data advances. We provide an overview of policies and programs in the U.S. and Canada that have been described as rural policy. Using basic descriptive evidence we show that to date the purported rural policy in both countries has generally failed to meet any broad-based objectives. We suggest that successful rural policy is primarily place-based, rather than being captured by tangential objectives such as support for particular sectors or initiatives such as environmental protection. We conclude by noting that government ministries that administer place-based (rural) policy should not have a sector-based orientation—rural policy should be removed from USDA and Agriculture and Agri-food Canada.

description: This short empirical study utilizes U.S. annual data from 1976 to 2006 to examine the causal relationship between energy consumption and employment in Illinois within a multi-variate framework. The Toda-Yamamoto long-run causality tests reveal unidirectional causal-ity from energy consumption to employment supportive of the growth hypothesis. However, the importance of energy consumption in economic activity should not overshadow the envi-ronmental consequences of heavy reliance on fossil fuel consumption as well as the relevance of alternative renewable energy sources and improved energy efficiency for future economic growth.

description: The ghost towns of the American West are both intriguing historical artifacts and reflec-tions of unique economic forces at work. In this study we develop linked labor and housing market models balancing the wages, rents, and local amenities of isolated boomtown sites to better understand the sources of such communities’ dramatic cycles. High variance boom-towns provide a unique context for investment in housing and other foundational infrastruc-ture, leading directly to the unusually transient local development patterns seen in ghost town settings. We use Colorado-based case studies to illustrate the relevance of the model. Comparisons with more modern rural settings in Appalachia and the Midwest suggest that the model provides a framework to better understand the process of rural decline more generally.

description: CMB anisotropy data could put powerful constraints on theories of the evolution of our Universe. Using the observations of the large number of CMB experiments, many studies have put constraints on cosmological parameters assuming different frameworks. Assuming for example inflationary paradigm, one can compute the confidence intervals on the different components of the energy densities, or the age of the Universe, inferred by the current set of CMB observations. The aim of this note is to present some of the available methods to derive the cosmological parameters with their confidence intervals from the CMB data, as well as some practical issues to investigate large number of parameters.

description: The intent of this applied research project is to build on the Roback-Blanchflower-Oswald model linking rent, wages and unemployment to amenities. Using non-metropolitan county level US data and detailed measures of natural and built amenities I estimate a struc-tural model testing for trade-offs between rent, wages, unemployment and amenities. Results do not strictly confirm the Roback-Blanchflower-Oswald (RBO) model but there is sufficient evidence to suggest that amenities plays an important role in explaining observed levels rent, wages and unemployment.

description: We calculate the quasinormal modes of a nonsingular spherically symmetric black hole effective model with holonomy corrections. The model is based on quantum corrections inspired by loop quantum gravity. It is covariant and results in a spacetime that is regular everywhere with a parameter-dependent black bounce. Perturbations of these black holes due to massless scalar and electromagnetic fields have been previously calculated and some intriguing results were observed. For some modes, the frequency versus minimum-radius parameter trajectories were found to spiral and self-intersect in the complex plane. In addition, the spectrum of overtones has real frequencies that oscillate with increasing overtone number, and may even vanish for some overtones. We have calculated the quasinormal modes for all massless spin perturbations, including spin-1/2, and axial- and polar-gravitational. We find that the trajectory-spirals are restricted to scalar perturbations and observe some interesting overtone behaviour for gravitational perturbations. The amount of isospectrality violation in the gravitational quasinormal mode spectra is also examined.

description: We discuss the proper definition of the spin current operator in Heisenberg magnets subject to inhomogeneous magnetic fields. We argue that only the component of the naive "current operator" J_ij S_i x S_j in the plane spanned by the local order parameters and is related to real transport of magnetization. Within a mean field approximation or in the classical ground state the spin current therefore vanishes. Thus, finite spin currents are a direct manifestation of quantum correlations in the system.

Year: 2009
Subjects: International Relations/Trade

description: This study provides an assessment of the potential impact of trade liberalization on the regional structure of Colombian agriculture. For this, a two-step methodology is imple-mented. First, the effects of discriminatory trade liberalization are estimated by means of a multi-region general equilibrium model. Second, relevant price and quantity changes are transmitted to a simple transportation model that simulates the likely changes that trade libe-ralization will bring upon the spatial structure of agriculture. Results indicate that changes in the spatial structure of agricultural production in Colombia are not negligible and are instru-mental for policy design on several fronts.

description: We investigate non-trivial topological structures in Discrete Light Cone Quantization (DLCQ) through the example of the broken symmetry phase of the two dimensional $ϕ^4$ theory using anti periodic boundary condition (APBC). We present evidence for degenerate ground states which is both a signature of spontaneous symmetry breaking and mandatory for the existence of kinks. Guided by a constrained variational calculation with a coherent state ansatz, we then extract the vacuum energy and kink mass and compare with classical and semi - classical results. We compare the DLCQ results for the number density of bosons in the kink state and the Fourier transform of the form factor of the kink with corresponding observables in the coherent variational kink state.

description: Extremely efficient convolutional neural network architectures are one of the most important requirements for limited-resource devices (such as embedded and mobile devices). The computing power and memory size are two important constraints of these devices. Recently, some architectures have been proposed to overcome these limitations by considering specific hardware-software equipment. In this paper, the lightweight residual densely connected blocks are proposed to guaranty the deep supervision, efficient gradient flow, and feature reuse abilities of convolutional neural network. The proposed method decreases the cost of training and inference processes without using any special hardware-software equipment by just reducing the number of parameters and computational operations while achieving a feasible accuracy. Extensive experimental results demonstrate that the proposed architecture is more efficient than the AlexNet and VGGNet in terms of model size, required parameters, and even accuracy. The proposed model has been evaluated on the ImageNet, MNIST, Fashion MNIST, SVHN, CIFAR-10, and CIFAR-100. It achieves state-of-the-art results on Fashion MNIST dataset and reasonable results on the others. The obtained results show the superiority of the proposed method to efficient models such as the SqueezNet. It is also comparable with state-of-the-art efficient models such as CondenseNet and ShuffleNet.

description: We obtain exact results for the acceptance ratio and mean squared displacement in Monte Carlo simulations of the simple harmonic oscillator in $D$ dimensions. When the trial displacement is made uniformly in the radius, we demonstrate that the results are independent of the dimensionality of the space. We also study the dynamics of the process via a spectral analysis and we obtain an accurate description for the relaxation time.

title: The limits of association studies in behavioral genetics: a revenge of sexual reproduction?
Creators: name: Bevilacqua, Arturo
Publisher: name: Organisms. Journal of Biological Sciences
Year: 2019

description: Genetic testing is showing its limits in assessing the hereditary risk for complex diseases as well as for psychic/psychiatric normal and pathological conditions. Genetic associations studies have revealed unable to produce consistent data on major disorders and more recent genome-wide association studies (GWAS) have provided more promising results identifying several genetic markers for individual risk of genetic diseases, but these generally consist of common variants that explain a small fraction of the overall genetic contribution to such risk. Even the mapping of copy number variations (CNVs) has so far produced inconsistent results. The future is thus to investigate how the alleles carried by our cells are expressed, and this is being pursued by two approaches: the study of our non-coding DNA, which is known to have an important role in the regulation of gene expression, and that of epigenetic mechanisms that represent the interface of gene x environment interactions and may allow us to better understand how neuronal populations direct behavior. As of now, the complex, multifactorial nature of our behavior and the continuous genotypic variation of human populations appear to represent the premise for such limits. Since sexual reproduction is the source of allelic assortment that makes our genetic variation continuous, it represents a strong restraint for geneticists.

description: Text-to-image (T2I) models, such as Stable Diffusion, have exhibited remarkable performance in generating high-quality images from text descriptions in recent years. However, text-to-image models may be tricked into generating not-safe-for-work (NSFW) content, particularly in sexually explicit scenarios. Existing countermeasures mostly focus on filtering inappropriate inputs and outputs, or suppressing improper text embeddings, which can block sexually explicit content (e.g., naked) but may still be vulnerable to adversarial prompts -- inputs that appear innocent but are ill-intended. In this paper, we present SafeGen, a framework to mitigate sexual content generation by text-to-image models in a text-agnostic manner. The key idea is to eliminate explicit visual representations from the model regardless of the text input. In this way, the text-to-image model is resistant to adversarial prompts since such unsafe visual representations are obstructed from within. Extensive experiments conducted on four datasets and large-scale user studies demonstrate SafeGen's effectiveness in mitigating sexually explicit content generation while preserving the high-fidelity of benign images. SafeGen outperforms eight state-of-the-art baseline methods and achieves 99.4% sexual content removal performance. Furthermore, our constructed benchmark of adversarial prompts provides a basis for future development and evaluation of anti-NSFW-generation methods.

description: While some of the most elegant applications of topological insulators, such as quantum anomalous Hall effect, require the preservation of Dirac surface states in the presence of time-reversal symmetry breaking, other phenomena such as spin-charge conversion rather rely on the ability for these surface states to imprint their spin texture on adjacent magnetic layers. In this work, we investigate the spin-momentum locking of the surface states of a wide range of monolayer transition metals (3$d$-TM) deposited on top of Bi$_{2}$Se$_{3}$ topological insulators using first principles calculations. We find an anticorrelation between the magnetic moment of the 3$d$-TM and the magnitude of the spin-momentum locking {\em induced} by the Dirac surface states. While the magnetic moment is large in the first half of the 3$d$ series, following Hund's rule, the spin-momentum locking is maximum in the second half of the series. We explain this trend as arising from a compromise between intra-atomic magnetic exchange and covalent bonding between the 3$d$-TM overlayer and the Dirac surface states. As a result, while Cr and Mn overlayers can be used successfully for the observation of quantum anomalous Hall effect or the realization of axion insulators, Co and Ni are substantially more efficient for spin-charge conversion effects, e.g. spin-orbit torque and charge pumping.

description: When annealing a 4H silicon carbide (SiC) crystal, a sequence of optically active defect centers occurs among which the TS center is a prominent example. Here, we present low-temperature photoluminescence analyses on the single defect level. They reveal that the three occurring spectral signatures TS1, TS2 and TS3 originate from one single defect. Their polarization dependences expose three different crystallographic orientations in the basal plane, which relate to the projections of the nearest neighbor directions. Accordingly, we find a three-fold level-splitting in ensemble studies, when applying mechanical strain. This dependency is quantitatively calibrated. A complementary electrical measurement, deep level transient spectroscopy, reveals a charge transition level of the TS defect at 0.6 eV above the valence band. For a future identification, this accurate characterization of its optical and electronic properties along with their response to mechanical strain is a milestone.

description: In this work, we present experimental results of a high-speed label-free imaging cytometry system that seamlessly merges the high-capturing rate and data sparsity of an event-based CMOS camera with lightweight photonic neuromorphic processing. This combination offers high classification accuracy and a massive reduction in the number of trainable parameters of the digital machine-learning back-end. The photonic neuromorphic accelerator is based on a hardware-friendly passive optical spectrum slicing technique that is able to extract meaningful features from the generated spike-trains. The experimental scenario comprises the discrimination of artificial polymethyl methacrylate calibrated beads, having different diameters, flowing at a mean speed of 0.01m/sec. Classification accuracy, using only lightweight, digital machine-learning schemes has topped at 98.2%. On the other hand, by experimentally pre-processing the raw spike data through the proposed photonic neuromorphic spectrum slicer we achieved an accuracy of 98.6%. This performance was accompanied by a reduction in the number of trainable parameters at the classification back-end by a factor ranging from 8 to 22, depending on the configuration of the digital neural network.

A Spatial Econometric Approach to Measuring Pollution Externalities: An Application to Ozone Smog

Year: 2010
Subjects: Environmental Economics and Policy

description: This paper uses spatial econometrics to analyze air pollution externalities. State-by-state source-receptor transfer coefficients that can be used as a basis for a location-differentiated permit system are estimated. Results affirm the importance of regional transport in determin-ing local ozone air quality, although owing to non-monotonicities in ozone production the ex-ternality is not always negative. Because the origin of emissions matters, results also reject a non-spatially differentiated NOx cap and trade program as an appropriate mechanism for re-ducing ozone smog.
