description: In this paper, we examine several methods of acquiring Czech data for automated fact-checking, which is a task commonly modeled as a classification of textual claim veracity w.r.t. a corpus of trusted ground truths. We attempt to collect sets of data in form of a factual claim, evidence within the ground truth corpus, and its veracity label (supported, refuted or not enough info). As a first attempt, we generate a Czech version of the large-scale FEVER dataset built on top of Wikipedia corpus. We take a hybrid approach of machine translation and document alignment; the approach and the tools we provide can be easily applied to other languages. We discuss its weaknesses and inaccuracies, propose a future approach for their cleaning and publish the 127k resulting translations, as well as a version of such dataset reliably applicable for the Natural Language Inference task - the CsFEVER-NLI. Furthermore, we collect a novel dataset of 3,097 claims, which is annotated using the corpus of 2.2M articles of Czech News Agency. We present its extended annotation methodology based on the FEVER approach, and, as the underlying corpus is kept a trade secret, we also publish a standalone version of the dataset for the task of Natural Language Inference we call CTKFactsNLI. We analyze both acquired datasets for spurious cues - annotation patterns leading to model overfitting. CTKFacts is further examined for inter-annotator agreement, thoroughly cleaned, and a typology of common annotator errors is extracted. Finally, we provide baseline models for all stages of the fact-checking pipeline and publish the NLI datasets, as well as our annotation platform and other experimental data.

description: We evaluate the percolation threshold values for a realistic model of continuum segregated systems, where random spherical inclusions forbid the percolating objects, modellized by hard-core spherical particles surrounded by penetrable shells, to occupy large regions inside the composite. We find that the percolation threshold is generally a non-monotonous function of segregation, and that an optimal (i. e., minimum) critical concentration exists well before maximum segregation is reached. We interpret this feature as originating from a competition between reduced available volume effects and enhanced concentrations needed to ensure percolation in the highly segregated regime. The relevance with existing segregated materials is discussed.

description: Most conventional crowd counting methods utilize a fully-supervised learning framework to establish a mapping between scene images and crowd density maps. They usually rely on a large quantity of costly and time-intensive pixel-level annotations for training supervision. One way to mitigate the intensive labeling effort and improve counting accuracy is to leverage large amounts of unlabeled images. This is attributed to the inherent self-structural information and rank consistency within a single image, offering additional qualitative relation supervision during training. Contrary to earlier methods that utilized the rank relations at the original image level, we explore such rank-consistency relation within the latent feature spaces. This approach enables the incorporation of numerous pyramid partial orders, strengthening the model representation capability. A notable advantage is that it can also increase the utilization ratio of unlabeled samples. Specifically, we propose a Deep Rank-consistEnt pyrAmid Model (DREAM), which makes full use of rank consistency across coarse-to-fine pyramid features in latent spaces for enhanced crowd counting with massive unlabeled images. In addition, we have collected a new unlabeled crowd counting dataset, FUDAN-UCC, comprising 4,000 images for training purposes. Extensive experiments on four benchmark datasets, namely UCF-QNRF, ShanghaiTech PartA and PartB, and UCF-CC-50, show the effectiveness of our method compared with previous semi-supervised methods. The codes are available at https://github.com/bridgeqiqi/DREAM.

description: Methods for training models on graphs distributed across multiple clients have recently grown in popularity, due to the size of these graphs as well as regulations on keeping data where it is generated. However, the cross-client edges naturally exist among clients. Thus, distributed methods for training a model on a single graph incur either significant communication overhead between clients or a loss of available information to the training. We introduce the Federated Graph Convolutional Network (FedGCN) algorithm, which uses federated learning to train GCN models for semi-supervised node classification with fast convergence and little communication. Compared to prior methods that require extra communication among clients at each training round, FedGCN clients only communicate with the central server in one pre-training step, greatly reducing communication costs and allowing the use of homomorphic encryption to further enhance privacy. We theoretically analyze the tradeoff between FedGCN's convergence rate and communication cost under different data distributions. Experimental results show that our FedGCN algorithm achieves better model accuracy with 51.7% faster convergence on average and at least 100X less communication compared to prior work.

description: The appearance of strangeness in the form of hyperons within the inner core of neutron stars is expected to affect its detectable properties such as its global structure or gravitational wave emission. In this work, we explore the parameter space of hyperonic stars within the framework of the Relativistic Mean Field model allowed by present uncertainties in state-of-the-art nuclear and hypernuclear experimental data. We impose multi-physics constraints at different density regimes to restrict the parameter space: Chiral effective field theory, heavy-ion collision data as well as multi-messenger astrophysical observations of neutron stars. We investigate possible correlations between empirical nuclear and hypernuclear parameters, particularly the symmetry energy and its slope, with observable properties of neutron stars. We do not find a correlation for the hyperon parameters and the astrophysical data. However, the inclusion of hyperons generates a tension between the astrophysical and heavy ion data constraining considerable the available parameter space.

description: This study focused on the analysis of the effect of tool geometry and hole quality on drilling carbon-fibre reinforced polymer (CFRP) composite using ANSYS. The experiment was conducted on computer numerical control machine (CNC) using high speed steel (HSS) twist drill bit and HSS-COBALT drill type. Taguchi L9 orthogonal array was used for the optimization analysis. Analysis of variance (ANOVA) was employed to determine the most significant control factors affecting the drilling process. The machining parameters involving tool type, point angle, spindle speed and feed rate were selected as control factors. While the dependable variables on workpiece were cutting force, stress and strain. The main interaction effect of the input variables on the predicted responses was investigated. The ANOVA/F-test results for cutting force with the contribution of each machining parameters revealed that the cutting speed was the dominant factor influencing cutting force developed with a contribution of 57 percent, The second factor affecting cutting force developed was point angle with a contribution of 5.7 percent, while feed rate had the least effect on cutting force developed where its contribution of 1.4 percent. Based on the results observed, the optimal machining parameters that produced minimum stress was observed with HSSCOBALT drill at 118 degrees of point angle, 300 mm/min of feed and 500 rpm of speed. Also from Taguchi results, the optimal combination of process parameters to obtain maximum strain with HSS drill, 135 degrees of point angle, and 300 mm/min of feed and 1500 rpm of speed produced the optimal drilling condition for CFRC polymer within the scope of this research work

The cinnamic acid pathway and hispidin biosynthesis in cultures of Polyporus hispidus Fries
Creators: name: Perrin, Peter William
Publisher: name: University of British Columbia
Year: 2011

description: The biosynthesis of hispidin, 6-(3,4-dihydroxystyryl)-4-hydroxy-2-pyrone, was examined in cultures of Polyporus hispidus Fr. Cultural studies were undertaken to determine the most suitable medium for investigating the biosynthesis of this pigment. These studies showed that light was necessary for hispidin formation and that the development of basidiocarps with viable spores could be achieved on agar media. On the liquid medium employed for biochemical studies, the maximum rate of hispidin production was observed to lag the maximum rate of growth by about five days. Trimethylhispidin, 4-methylhispidin and yangonin were synthesized for comparative purposes and for dilution in tracer experiments. These and numerous other phenolic and aromatic compounds were employed as references in examinations of nonradioactive culture extracts. P-coumaric, caffeic, p-hydroxybenzoic, protocatechuic and o- and p-hydroxyphenyl-acetic acids were detected in extracts of the culture medium. Bis-noryangonin (6-(4-hydroxystyryl)-4-hydroxy-2-pyrone) and other possible styrylpyrones were detected in extracts of the mycelium. Tracer experiments established that phenylalanine was metabolized to cinnamic, benzoic, p-hydroxybenzoic and protocatechuic acids. The incorporation of radioactivity into phenyllactic, phenylpyruvic, phenylacetic and p-hydroxy-phenylacetic acids also was observed. Furthermore, p-coum-aric acid, caffeic acid and hispidin incorporated radioactivity from phenylalanine. Hispidin also was shown to incorporate radioactivity from tyrosine, cinnamic acid, p-coum-aric acid, caffeic acid, malonic acid and sodium acetate. Degradation of the labelled hispidin obtained from these precursors confirms the hypothesis that this molecule is bio-synthesized from a phenylpropanoid moiety with the addition of two equivalents of acetate. Crude and partially purified preparations of several enzymes related to aromatic metabolism were obtained. Phenylalanine and tyrosine ammonia-lyase activity were demonstrated in cell-free preparations. Maximum phenylalanine ammonia-lyase activity was obtained from cultures during the logarithmic phase of growth. Enzymes capable of hydroxylating cinnamic acid, benzoic acid and bis-noryangonin also were obtained in vitro.

Using Sato's formulation, we show the integrability and construct some special solutions. An elliptic solution is also obtained. We present a conjecture based on a Poisson structure that it gives an alternative description of this integrable hierarchy. We note that this Poisson algebra in turn is related to a quantum algebra related with the family of Macdonald difference operators.

description: In recent years, the methods on matrix-based or bilinear discriminant analysis (BLDA) have received much attention. Despite their advantages, it has been reported that the traditional vector-based regularized LDA (RLDA) is still quite competitive and could outperform BLDA on some benchmark datasets. Nevertheless, it is also noted that this finding is mainly limited to image data. In this paper, we propose regularized BLDA (RBLDA) and further explore the comparison between RLDA and RBLDA on another type of matrix data, namely multivariate time series (MTS). Unlike image data, MTS typically consists of multiple variables measured at different time points. Although many methods for MTS data classification exist within the literature, there is relatively little work in exploring the matrix data structure of MTS data. Moreover, the existing BLDA can not be performed when one of its within-class matrices is singular. To address the two problems, we propose RBLDA for MTS data classification, where each of the two within-class matrices is regularized via one parameter. We develop an efficient implementation of RBLDA and an efficient model selection algorithm with which the cross validation procedure for RBLDA can be performed efficiently. Experiments on a number of real MTS data sets are conducted to evaluate the proposed algorithm and compare RBLDA with several closely related methods, including RLDA and BLDA. The results reveal that RBLDA achieves the best overall recognition performance and the proposed model selection algorithm is efficient; Moreover, RBLDA can produce better visualization of MTS data than RLDA.

description: We develop a variant of the generalized slow roll approach for calculating the curvature power spectrum that is well-suited for order unity deviations in power caused by sharp features in the inflaton potential. As an example, we show that predictions for a step function potential, which has been proposed to explain order unity glitches in the CMB temperature power spectrum at multipoles l=20-40, are accurate at the percent level. Our analysis shows that to good approximation there is a single source function that is responsible for observable features and that this function is simply related to the local slope and curvature of the inflaton potential. These properties should make the generalized slow roll approximation useful for inflation-model independent studies of features, both large and small, in the observable power spectra.

Radiative Corrections on the $B\to P$ Form Factors with Chiral Current in the Light-Cone Sum Rules

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Based on the approach of the vector form factor $F^{+}_{B\toπ, K}(q^2)$ in our previous papers, we extend the calculation of the radiative corrections to the $B\to P$ ($P$ stands $π$, $K$ and all light pseudoscalar mesons) scalar and tensor form factors $F^{0,T}_{B\to P}(q^2)$ with chiral current in the light-cone sum rules (LCSRs). The most uncertain twist-3 contributions to the $B\to P$ form factors can be naturally eliminated through a properly designed correlator. We present the next-leading-order formulae of $F^{+,0,T}_{B\to P}(q^2)$ with the $b$-quark pole mass that is universal. It has been shown that our results are simpler and less uncertain under the same parameter regions since we only need to calculate the next leading order on the twist-2 part from the obtained LCSR. Second, we obtain $f^{+,0}_{B\toπ}(0)=0.260^{+0.059}_{-0.040}$, $f^{T}_{B\toπ}(0)=0.276^{+0.052}_{-0.039}$, $f^{+,0}_{B\to K}(0)=0.334^{+0.094}_{-0.069}$ and $f^{T}_{B\to K}(0) =0.379^{+0.092}_{-0.077}$ at $q^2=0$ and the $SU_f(3)$-breaking effects are discussed too.

Direct mapping between exchange potentials of Hartree-Fock and Kohn-Sham schemes as origin of orbitals proximity

description: It is found that, in closed-$l$-shell atoms, the exact local exchange potential $v_{\text{x}}(\bf r)$ of the density functional theory (DFT) is very well represented, within the region of every atomic shell, by each of the suitably shifted potentials obtained with the non-local Fock exchange operator for the individual Hartree-Fock (HF) orbitals belonging to this shell. Consequently, the continuous piecewise function built of shell-specific exchange potentials, each defined as the weighted average of the shifted orbital exchange potentials corresponding %the HF orbitals from to a given shell, yields another highly-accurate representation of $v_{\text{x}}(\bf r)$. These newly revealed properties are {\em not} related to the well-known step-like shell structure in the response part of $v_{\text{x}}(\bf r)$, but they result from specific relations satisfied by the HF orbital exchange potentials. These relations explain the outstanding proximity of the occupied Kohn-Sham and HF orbitals as well as the high quality of the Krieger-Li-Iafrate and localized HF (or, equivalently, common-energy-denominator) approximations to the DFT exchange potential $v_{\text{x}}(\bf r)$. The constant shifts added to the HF orbital exchange potentials, to map them onto $v_{\text{x}}(\bf r)$, are nearly equal to the differences between the energies of the corresponding KS and HF orbitals. It is discussed why these differences are positive and grow when the respective orbital energies become lower for inner orbitals.

description: The formation of multiple beads along an injured axon will lead to blockage of axonal transport and eventually neuron death, and this has been widely recognized as a hallmark of nervous system degeneration. Nevertheless, the underlying mechanisms remain poorly understood. Here, we report a combined experimental and theoretical study to reveal key factors governing axon beading. Specifically, by transecting well-developed axons with a sharp atomic force microscope probe, significant beading of axons was triggered. We showed that adhesion was not required for beading to occur, although when present strong axon–substrate attachments seemed to set the locations for bead formation. In addition, the beading wavelength, representing the average distance between beads, was found to correlate with the size and cytoskeleton integrity of axon, with a thinner axon or a disrupted actin cytoskeleton both leading to a shorter beading wavelength. A model was also developed to explain these observations which suggest that axon beading originates from the shape instability of the membrane and is driven by the release of work done by axonal tension as well as the reduction of membrane surface energy. The beading wavelength predicted from this theory was in good agreement with our experiments under various conditions. By elucidating the essential physics behind axon beading, the current study could enhance our understanding of how axonal injury and neurodegeneration progress as well as provide insights for the development of possible treatment strategies.
An investigation into the relationship between student characteristics and the inquiry method of teaching science

description: Five instruments were used to collect data on student characteristics: the Combined Cognitive Preference Inventory, a modified Cognitive Style of Categorization Behaviour, the Test Of Science Related Attitudes, the Structures of Observed Learning Outcomes and a designed Student Perceived Characteristics of Success instruments. In this research five classes were taught science using the inquiry method. One of the treatment classes was matched to a control class taught conventionally. The data collected were analyzed in two different ways. First, the data of the five treatment classes were analyzed using non-parametric statistics. It was found that students who coped well with the inquiry method had significantly different characteristics than students who did not cope well. The distinctions between successful and unsuccessful inquiry students differed significantly between ability levels. A model was developed to show the hierarchal nature of inquiry student characteristics at different stages of cognitive development. Second, the data of the matched control and treatment classes were analyzed using parametric statistics. Student characteristics were incorporated in linear regression equations and it was found that the regression equations for control students were significantly different from the regression equations for inquiry students.

The social bases of environmentalism in Australia
Creators: name: Tranter, Bruce

description: The nature of support for environmentalism - conceptualised here as attitudes and behaviour supportive of ecological prudence and the green movement - has grown to become a major issue of contention among contemporary social scientists. Some researchers suggest that support for environmentalism stems from a 'new' or 'new middle' class, post World War II generation and, in particular, from among highly educated and left leaning urban dwellers. Others maintain that social location has diminishing utility for explaining social phenomena, and claim instead that new value orientations are the key to understanding support for environmental movements and concerns. This research aims at reviewing and evaluating these claims. Part I reviews the theoretical arguments underlying the diverse class, generation and social status accounts of environmentalism. Critical evaluation of these accounts forms a springboard for empirical analysis. Part II examines empirically the social bases of environmentalism in Australia using nationally representative survey data. The impact of (new) class, status group, generation/cohort, and other aspects of social location, as well as 'postmaterial' values on environmental concerns and activism is assessed using multivariate techniques. Particular attention is paid to the hypothesis that support for environmentalism in Australia comes from certain status categories of people sharing similar lifestyles. In general, there is a weak relationship between social location and environmental commitment and activism, although the relative explanatory value of social location varies according to the aspect of environmentalism under consideration. Age, new class location, postmaterialist value orientations and political partisanship are the best predictors of environmental concerns and activism, while lifestyle also has an impact upon environmental group support. While 'social base' effects are discernible, they have limited utility for explaining environmental new politics. Like other aspects of the new politics, environmental concerns and activism in Australia are detached from the 'old' social bases of class, generation and status. Green supporters and sympathisers in Australia do not form clearly circumscribed social groupings, and they do not seem to be motivated by the traditional group interests that propelled 'old' politics. The social constituencies of environmentalism appear to be vague and fluid thus posing a major challenge to the established sociological approaches to environmentalism.

description: Spiking Neural Networks (SNNs) are developed as a promising alternative to Artificial Neural networks (ANNs) due to their more realistic brain-inspired computing models. SNNs have sparse neuron firing over time, i.e., spatio-temporal sparsity; thus, they are useful to enable energy-efficient hardware inference. However, exploiting spatio-temporal sparsity of SNNs in hardware leads to unpredictable and unbalanced workloads, degrading the energy efficiency. In this work, we propose an FPGA-based convolutional SNN accelerator called Skydiver that exploits spatio-temporal workload balance. We propose the Approximate Proportional Relation Construction (APRC) method that can predict the relative workload channel-wisely and a Channel-Balanced Workload Schedule (CBWS) method to increase the hardware workload balance ratio to over 90%. Skydiver was implemented on a Xilinx XC7Z045 FPGA and verified on image segmentation and MNIST classification tasks. Results show improved throughput by 1.4X and 1.2X for the two tasks. Skydiver achieved 22.6 KFPS throughput, and 42.4 uJ/Image prediction energy on the classification task with 98.5% accuracy.

Introductory (graphical) linear programming in the senior secondary school : an action research study of some cognitive obstacles to its learning and an evaluation of a teaching approach designed to reduce the effect of these cognitive obstacles
Creators: name: White, Kevin M A
Publisher: name: University Of Tasmania
Year: 2023

description: This action research study, in two parts, investigates the difficulties experienced by senior secondary (Year 12) students in learning to solve by graphical means linear programming problems involving two decision variables. Herscovics' (1989) term \cognitive obstacle\" is introduced as describing either a mental structure which prevents the learning of new material or the structure of the material itself which prevents it from being readily assimilated. The aim of the first part of the study is to determine possible cognitive obstacles to the learning of linear programming. The aim of the second part is to evaluate a teaching programme designed to alleviate these cognitive obstacles. It is found that the teaching programme used based around a set of specific heuristics is partially successful. It is suggested that key factors in solving linear programming problems include: the ability to comprehend problem statements the ability to express variables and constraints on variables in mathematical terms and the ability to conceive of literal symbols as representing numbers rather than as objects. Various ideas for teaching and research are recommended."

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

On the evolution of anomalous X-ray pulsars and soft gamma ray repeaters with fallback disks

description: We show that the period clustering of anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs), their X-ray luminosities, ages and statistics can be explained with fallback disks with large initial specific angular momentum. The disk evolution models are developed by comparison to self-similar analytical models. The initial disk mass and angular momentum set the viscous timescale. An efficient torque, with (1 - w^2) dependence on the fastness parameter w leads to period clustering in the observed AXP-SGR period range under a wide range of initial conditions. The timescale t_0 for the early evolution of the fallback disk, and the final stages of fallback disk evolution, when the disk becomes passive, are the crucial determinants of the evolution. The disk becomes passive at temperatures around 100 K, which provides a natural cutoff for the X-ray luminosity and defines the end of evolution in the observable AXP and SGR phase. This low value for the minimum temperature for active disk turbulence indicates that the fallback disks are active up to a large radius greater than ~10^{12} cm. We find that transient AXPs and SGRs are likely to be older than their persistent cousins. A fallback disk with mass transfer rates corresponding to the low quiescent X-ray luminosities of the transient sources in early evolutionary phases would have a relatively lower initial mass, such that the mass-flow rate in the disk is not sufficient for the inner disk to penetrate into the light cylinder of the young neutron star, making mass accretion onto the neutron star impossible. The transient AXP phase therefore must start later. The model results imply that the transient AXP/SGRs, although older, are likely to be similar in number to persistent sources (abridged).
