description: The numerical solution of Huxley equation by the use of two finite difference methods is done. The first one is the explicit scheme and the second one is the Crank-Nicholson scheme. The comparison between the two methods showed that the explicit scheme is easier and has faster convergence while the Crank-Nicholson scheme is more accurate. In addition, the stability analysis using Fourier (von Neumann) method of two schemes is investigated. The resulting analysis showed that the first scheme is conditionally stable if, r ≤ 2 − aβ∆t , ∆t ≤ 2(∆x)2 and the second scheme is unconditionally stable.

description: Item-based models are among the most popular collaborative filtering approaches for building recommender systems. Random walks can provide a powerful tool for harvesting the rich network of interactions captured within these models. They can exploit indirect relations between the items, mitigate the effects of sparsity, ensure wider itemspace coverage, as well as increase the diversity of recommendation lists. Their potential, however, can be hindered by the tendency of the walks to rapidly concentrate towards the central nodes of the graph, thereby significantly restricting the range of K-step distributions that can be exploited for personalized recommendations. In this work we introduce RecWalk; a novel random walk-based method that leverages the spectral properties of nearly uncoupled Markov chains to provably lift this limitation and prolong the influence of users' past preferences on the successive steps of the walk---allowing the walker to explore the underlying network more fruitfully. A comprehensive set of experiments on real-world datasets verify the theoretically predicted properties of the proposed approach and indicate that they are directly linked to significant improvements in top-n recommendation accuracy. They also highlight RecWalk's potential in providing a framework for boosting the performance of item-based models. RecWalk achieves state-of-the-art top-n recommendation quality outperforming several competing approaches, including recently proposed methods that rely on deep neural networks.

description: We compare the probability distribution of returns for the three major stock-market indexes (Nasdaq, S&P500, and Dow-Jones) with an analytical formula recently derived by Dragulescu and Yakovenko for the Heston model with stochastic variance. For the period of 1982-1999, we find a very good agreement between the theory and the data for a wide range of time lags from 1 to 250 days. On the other hand, deviations start to appear when the data for 2000-2002 are included. We interpret this as a statistical evidence of the major change in the market from a positive growth rate in 1980s and 1990s to a negative rate in 2000s.

description: This work studies the natural pigment profiles (chlorophylls and carotenoids) of Spanish Extra Virgin Olive Oils (EVOO) produced in different Spanish regions. The simultaneous qualitative and quantitative analysis of EVOO natural pigments has been performed by ultra-high-performance liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) using atmospheric pressure chemical ionisation (APCI). The results showed a similar natural pigment pattern for all the analysed EVOOs, although the total pigments content differed significantly. Moreover, the chlorophyll/carotenoid ratio was close to 1, while the lutein/β-carotene ratio was higher than 1, showing that lutein is the most abundant carotenoid in the studied Spanish EVOOs. Data from multivariate statistical approach demonstrated that the olive variety does not discriminate between EVOO samples. However, they were classified based on their origin allowing good differentiation of samples from the Basque Country and Canary Islands from the rest of regions. The results of this study show the differences of the nature and pigments concentration of Spanish EVOO samples, parameters that are of significance for reliable characterisation.

description: To compare the inter-camera performance and consistency of various deep learning (DL) diagnostic algorithms applied to fundus images taken from desktop Topcon and portable Optain cameras. Participants over 18 years of age were enrolled between November 2021 and April 2022. Pair-wise fundus photographs from each patient were collected in a single visit; once by Topcon (used as the reference camera) and once by a portable Optain camera (the new target camera). These were analyzed by three previously validated DL models for the detection of diabetic retinopathy (DR), age-related macular degeneration (AMD), and glaucomatous optic neuropathy (GON). Ophthalmologists manually analyzed all fundus photos for the presence of DR and these were referred to as the ground truth. Sensitivity, specificity, the area under the curve (AUC) and agreement between cameras (estimated by Cohen’s weighted kappa, K) were the primary outcomes of this study. A total of 504 patients were recruited. After excluding 12 photographs with matching errors and 59 photographs with low quality, 906 pairs of Topcon-Optain fundus photos were available for algorithm assessment. Topcon and Optain cameras had excellent consistency (Κ=0.80) when applied to the referable DR algorithm, while AMD had moderate consistency (Κ=0.41) and GON had poor consistency (Κ=0.32). For the DR model, Topcon and Optain achieved a sensitivity of 97.70% and 97.67% and a specificity of 97.92% and 97.93%, respectively. There was no significant difference between the two camera models (McNemar’s test: x2=0.08, p = .78). Topcon and Optain cameras had excellent consistency for detecting referable DR, albeit performances for detecting AMD and GON models were unsatisfactory. This study highlights the methods of using pair-wise images to evaluate DL models between reference and new fundus cameras.
Deep Learning for Classification and Denoising of Cosmic-Ray Radio Signals

description: Radio emission, produced mainly as a result of the geomagnetic deflection of oppositely charged particles within the cosmic-ray air showers, is contaminated by backgrounds such as the continuous Galactic background and thermal noise. This irreducible background poses a significant challenge for radio detection of air showers. To mitigate this effect of background we employ machine learning (ML) techniques. These techniques such as convolutional neural networks (CNNs) have been widely used to analyze visual imagery. It is only recently that these techniques have been adopted in many fields of science for the purpose of recognizing different patterns in the data. In this work, we use CNNs with the following two goals: to classify waveforms with signals against those that include only noise and to extract the underlying radio signals from the contaminated traces. To produce the required dataset for training the models, we use CoREAS simulations which calculate the radio signals from air showers. For background we considered Cane Model for average Galactic noise, with an additional thermal component. Both signal and background traces are filtered in the 50 - 350 MHz frequency band before training. With these ML models, we aim to improve the detection threshold and also the reconstruction efficiency of the radio technique for cosmic-ray air showers.

description: In this study, the appearance and texture of E. rutaecarpa were linked with the chemical constituents to explore methods of classification of E. rutaecarpa. The Chemometrics such as Hierarchical cluster analysis (HCA), principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) models were used for analysis. According to the models, samples of E. rutaecarpa were divided into three categories based on their source: Evodia, Stone Tiger and Sparse Evodia. The Evodia category could be subdivided into two categories, one representing large fruits with a greater degree of cracking and the other representing large fruits with little or no cracking. The method provided by this study combines chemometrics with HPLC fingerprints, which can provide a basis and reference for the identification of E. rutaecarpa and enables establishment of a grade standard.

description: Traditional markets in Asian countries still account for the majority of fresh meat, fish and vegetable purchases. One of the reasons for their popularity is the relational trust between vendors and buyers. This trust may justify the limited availability of information on origin or production methods and other attributes of foods sold in these markets. However, a number of recent food safety outbreaks and food fraud cases raised consumer and government concerns on over the level information in these markets and ignited a reflection of possible action. This study aims to determine the consumer willingness to pay (WTP) for fresh meat traceability and free growth hormone information traditional markets in Taiwan. To estimate the values of information the payment card method was employed and to account for the starting point bias, the sample was divided into different treatments each with a different price of meat. A total of 2,381 completed survey were collected in mid-July, 2015. An interval regression model is utilized to examine how much consumers would be willing to pay for addition product information. The results suggest that WTP of information not consistent among groups with different starting point scenarios. There was a significant difference between respondents that were not given any indication of the price per quantity of meat and those that were prompted with a market price. Interestingly, we found that consumers treat the information of growth hormone-free examination and traceability differently.

The Influence of the Gravitational Acceleration on the Supernova-Driven P arker Instability

description: Within a framework of 2D MHD simulations, we explore the dynamical regimes initi ated by a supernova explosion in a magnetized stratified ISM. We concentrate on the formation of large scale magnetic structures and outflows connected with the Parker instability. For the sake of simplicity we show only models with a fixed explosion energy corresponding to a single SN occuring in host galaxies with different fixed values of the gravitational acceleration $g$ and different ratios of specific heats. We show that in general depending on these two parameters, three different regimes are possible: a) a slowly growing Parker instability on time scales much longer than the galac tic rotation period for small $g$, b) the Parker instability growing at roughly the rotation period, which for ratios of specific heats larger than 1 is accompanied byan outflow resulting from the explosion for intermediate $g$, and c) a rapidly g rowing instability and a strong blowout flow for large $g$. By means of numerical simul ations and analytical estimates we show that the explosion energy and gravitational acceleration which separate the three regimes scale as $Eg^2\sim $const in the 2D case. We expect that in the 3D case this scaling law is $Eg^3\sim $const. Our simulations demonstrate furthermore, that a single SN explosion can lead to the growth of multiple Parker loops in the disc and large scale magnetic field loops in the halo, extending over 2-3 kpc horizontally and up to 3 kpc vertically abov e the midplane of the disc.

In particular, we discuss the general form of acceptable generators for continuous (Lie-point) W-symmetry, arguing they are related to the (linear) conformal group, and how W-symmetries can be used in the integration of Ito stochastic equations along Kozlov theory for standard (deterministic or random) symmetries. It turns out this requires, in general, to consider more general classes of stochastic equations than just Ito ones.

description: We report on the results of an I-band photometric variability survey of eighteen L dwarfs. We find that seven exhibit statistically significant variations above the 95.4% confidence level with root-mean-square scatter (including photometric errors) between 0.010 and 0.083 mag. Another five targets have variability probabilities ~80%, suggesting that these are likely variable objects. Three of the variable objects display significant peaks in a CLEAN periodogram that are several times higher than the noise. The period for 2MASS 0345+25 is clearly not intrinsic to the object and can be dismissed. The periods found for 2MASS 0746+20AB and 2MASS 1300+19 are unique but longer than those periods likely from rotation velocity measurements and they do not represent periodic behavior in the light curve that persists through the entire data set. These observations suggest that we are not observing the rotation modulation of a long-lived albedo feature. Instead, rapid evolution of atmospheric features is likely causing the non-periodic variability. The remaining variable objects show no prominent features in their light curves, suggesting even more rapid evolution of atmospheric features. We argue against the existence of magnetic spots in these atmospheres and favor the idea that non-uniform condensate coverage is responsible for these variations. The magnetic Reynolds number in the atmosphere of L dwarfs is too small to support the formation of magnetic spots. In contrast, silicate and iron clouds are expected to form in the photospheres of L dwarfs. Inhomogeneities in such cloud decks and the evolution of the inhomogeneities can plausibly produce the observed photometric variations.

description: In this work, we describe a method developed to quantify persistent organic pollutants (POPs) including polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs) in dietary supplement samples using stir-bar sorptive extraction (SBSE)-GC-MS/MS-isotope dilution mass spectrometry (IDMS). This method enables accurate, precise, and sensitive quantification of POPs in plant-extract based dietary supplement products commercially available in the United States. When compared with calibration curves, IDMS provided more accurate and precise measurements. The mean error of measurements using this method was 7.24% with a mean RSD of 8.26%. The application of GC-MS/MS enabled approximately two-order-of-magnitude lower limit of quantifications compared with GC-MS. 12 commercially available plant-extract based dietary supplement samples were analysed using this method. PAHs including naphthalene, acenaphthene, fluorene, phenanthrene, fluoranthene, pyrene, chrysene, and benzo[a]pyrene were detected in most of the products and had average concentrations over 1 ng/g. OCPs were detected less frequently than PAHs in these products, and none of the OCPs had mean concentrations over 1 ng/g. The mean toxin concentration of each product was calculated, and the highest value was 3.20 ng/g. These results were compared with existing guidelines and none of the analytes in the samples were found to be above the daily allowable limits.

description: This study was conducted to determine the effects of diet supplementation of laying hens with Enterococcus faecalis (EF) on egg production, egg quality and caecal microbiota. A total of 360 Hy-Line Brown laying hens (72 weeks old) were divided into three groups with four replicates of 30 birds each. The laying hens were fed with the basal diet (Control), the basal diet + 3.75 · 108 cfu EF/kg (Group I) or the basal diet + 7.5 · 108 cfu EF/kg (Group II). The experiment lasted for 45 d. Eggs and caecal samples were collected at the end of the experiment. Results showed that dietary supplementation with EF did not affect the average daily egg weight, cracked egg rate, mortality and egg quality. However, EF supplementation caused a significantly increased laying rate and decreased feed/egg ratio (p < 0.05). The differences in caecal microbiota between Group II and the Control were significant. The relative abundance of Verrucomicrobia and Cyanobacteria at the phylum level, Rikenellaceae, Christensenellaceae and Veillonellaceae at the family level, and the Faecalibacterium, Christensenellaceae R-7 group and Eubacterium coprostanoligenes group at the genus level changed significantly in Group II compared with the Control (p < 0.05). In conclusion, the tested dietary supplementations with EF improved product performance and affected the caecal microbial community structure of laying hens during the late laying period.

description: We study space–time finite element methods for semilinear parabolic problems in (1 + d)–dimensions for d = 2, 3. The discretisation in time is based on the discontinuous Galerkin timestepping method with implicit treatment of the linear terms and either implicit or explicit multistep discretisation of the zeroth order nonlinear reaction terms. Conforming finite element methods are used for the space discretisation. For this implicit-explicit IMEX–dG family of methods, we derive a posteriori and a priori energy-type error bounds and we perform extended numerical experiments. We derive a novel hp–version a posteriori error bounds in the L∞(L2) and L2(H1) norms assuming an only locally Lipschitz growth condition for the nonlinear reactions and no monotonicity of the nonlinear terms. The analysis builds upon the recent work in [60], for the respective linear problem, which is in turn based on combining the elliptic and dG reconstructions in [83, 84] and continuation argument. The a posteriori error bounds appear to be of optimal order and efficient in a series of numerical experiments. Secondly, we prove a novel hp–version a priori error bounds for the fully–discrete IMEX–dG timestepping schemes in the same setting in L∞(L2) and L2(H1) norms. These error bounds are explicit with respect to both the temporal and spatial meshsizes kn and h, respectively, and, where possible, with respect to the possibly varying temporal polynomial degree r. The a priori error estimates are derived using the elliptic projection technique with an inf-sup argument in time. Standard tools such as Grönwall inequality and discrete stability estimates for fully discrete semilinear parabolic problems with merely locally-Lipschitz continuous nonlinear reaction terms are used. The a priori analysis extends the applicability of the results from [52] to this setting with low regularity. The results are tested by an extensive set of numerical experiments.

description: A numerical solution for Sine-Gordon type system was done by the use of two finite difference schemes, the first is the explicit scheme and the second is the Crank-Nicholson scheme. A comparison between the two schemes showed that the explicit scheme is easier and has faster convergence than the Crank-Nicholson scheme which is more accurate. The MATLAB environment was used for the numerical computations.

description: Conservation return on investment (ROI), for all spatial scales, varies according to a wide range of characteristics. One feature that makes conservation ROI at the parcel level different from larger scale ROI is the impact of parcel size variation on ecological and economic effectiveness. Protected area size maintains an important role in both the benefit and cost associated with conservation. However, few studies have explicitly focused on the role of protected area size on conservation ROI specifically at the parcel level. Therefore, conservation ROI has been limited in its effectiveness in prioritizing parcels for conservation. The objective of our research is to examine how protected area size influences a parcel’s ecological and economic effectiveness through conservation ROI. This objective is accomplished by analyzing the parcel- level acquisition cost and the conservation benefit of protected areas acquired by a conservation organization, The Nature Conservancy (TNC). We develop an empirical model to examine how differences in protected area size influence conservation benefit as an ecological measurement, and how differences in the conservation benefit, as a measurement of conservation value, subsequently alter conservation cost. By assessing the sequential relationship in a spatial econometric modeling framework, we first examine the consequence of the size variation on conservation ROI and then we calculate and rank the ROI for each protected area with and without considering the spatial spillovers of conservation benefit and acquisition cost. We found that (1) protected areas acquired by TNC create more connected habitat, thereby improving species protection and mobility in the existing protected area network that existed prior to the TNC acquisition, and subsequently, such improvement is a major impetus to determine acquisition cost, (2) the increase in effective mesh size per dollar invested to acquire a parcel is greater for larger parcels than smaller parcels, implying that the overall efficiency that considers both ecological and economic efficiencies is higher for protecting larger areas relative to smaller ones, and (3) the inclusion of spillovers of both conservation benefit and cost in the ROI decision-making tool provides information about which parcels’ locations affect conservation benefit and cost in their neighboring parcels and to what extent.

description: In the present work, we investigate $P_c(4312)$, $P_c(4440)$ and $P_c(4457)$ production from $Λ_b$ decay in a molecular scenario by using an effective Lagrangian approach. We predict the ratio of the branching fraction of $Λ_b \to P_c K$, which is weakly dependent on our model parameter. We also find the ratios of the productions of the branching fractions of $Λ_b \to P_c K$ and $P_c \to J/ψp$ can be well interpreted in the molecular scenario. Moreover, the estimated branching fractions of $Λ_b \to P_c K$ are of order $10^{-6}$, which could be tested by further measurements in LHCb Collaboration.

description: We study the dynamics of coupled dipolar oscillations in a Fermi-Bose mixture of $^{40}$K and $^{87}$Rb atoms. This low-energy collective mode is strongly affected by the interspecies interactions. Measurements are performed in the dynamical and quantum degenerate regimes and evidence the crucial role of the statistical properties of the mixture. At the onset of quantum degeneracy, we investigate the role of Pauli blocking and superfluidity for K and Rb atoms, respectively, resulting in a change in the collisional interactions.

description: Fourier and related transforms is a family of algorithms widely employed in diverse areas of computational science, notoriously difficult to scale on high-performance parallel computers with large number of processing elements (cores). This paper introduces a popular software package called P3DFFT implementing Fast Fourier Transforms (FFT) in three dimensions (3D) in a highly efficient and scalable way. It overcomes a well-known scalability bottleneck of 3D FFT implementations by using two-dimensional domain decomposition. Designed for portable performance, P3DFFT achieves excellent timings for a number of systems and problem sizes. On Cray XT5 system P3DFFT attains 45% efficiency in weak scaling from 128 to 65,536 computational cores. Library features include Fourier and Chebyshev transforms, Fortran and C interfaces, in- and out-of-place transforms, uneven data grids, single and double precision. P3DFFT is available as open source at http://code.google.com/p/p3dfft/. This paper discusses P3DFFT implementation and performance in a way that helps guide the user in making optimal choices for parameters of their runs.

description: Numerical solution of oscillatory reaction–diffusion system of $\lambda-omega$ type was done by using two finite difference schemes . The first one is the explicit scheme and the second one is the implicit rank– Nicholson scheme with averaging of f (u,v) and without averaging of f (u,v). The comparison showed that Crank–Nicholson scheme is better than explicit scheme and Crank–Nicholson scheme with averaging of ff (u,v) is more accurate but it needs more time and double storage and double time steps than Crank–Nicholson scheme without averaging of f (u,v).
