Statistically Significant Dependencies for Spatial Co-location Pattern Mining and Classification Association Rule Discovery

Spatial co-location pattern mining and classification association rule discovery are two canonical tasks studied in the data mining community. Both of them focus on the detection of sets of features that show associations. The difference is that in spatial co-location pattern mining, the features are all spatial features which contain location information. While in classification association rule discovery, we constrain the mining process to generate association rules that always have as consequent a class label. Existing methods on these two tasks mostly use the support-confidence framework in an Apriori-like way or through a FP-growth approach to mine the co-location patterns and classification association rules which require the setting of confounding parameters. However, the lack of statistical dependencies between features in the used framework may lead to the omission of many interesting patterns and/or the detection of meaningless rules. To address the above limitations, we fully exploit the property of statistical significance and propose two novel algorithms for these two tasks, respectively. The CMCStatApriori, a co-location mining algorithm, is able to detect more general and statistically significant co-location rules. We use it on real datasets with the National Pollutant Release Inventory (NPRI), and propose a classification scheme to help evaluate the discovered co-location rules. The second algorithm, SigDirect, an associative classifier, aims to mine classification association rules which show statistically significant dependencies between a set of antecedent features and a class label. Experimental results on UCI datasets show that SigDirect achieves a competitive if not better classification performance while indeed produces a very small number of rules. We also show the potential of integrating statistically significant negative classification association rules in the SigDirect algorithm.
The Finite Volume WENO with Lax–Wendroff Scheme for Nonlinear System of Euler Equations

We develop a Lax–Wendroff scheme on time discretization procedure for finite volume weighted essentially non-oscillatory schemes, which is used to simulate hyperbolic conservation law. We put more focus on the implementation of one-dimensional and two-dimensional nonlinear systems of Euler functions. The scheme can keep avoiding the local characteristic decompositions for higher derivative terms in Taylor expansion, even omit partly procedure of the nonlinear weights. Extensive simulations are performed, which show that the fifth order finite volume WENO (Weighted Essentially Non-oscillatory) schemes based on Lax–Wendroff-type time discretization provide a higher accuracy order, non-oscillatory properties and more cost efficiency than WENO scheme based on Runge–Kutta time discretization for certain problems. Those conclusions almost agree with that of finite difference WENO schemes based on Lax–Wendroff time discretization for Euler system, while finite volume scheme has more flexible mesh structure, especially for unstructured meshes.
Goal difficulty level and perceived competence on volleyball serve learning

The purpose of this study was to evaluate the effect of the goal difficulty level on the volleyball serve learning and if the perceived sports competence mediates this process. Adolescent volunteers (N = 22, age = 14.0 ± 0.9 years) participated in this study performing the volleyball serve. Two experimental groups were formed: high difficult goal group (HDG; n = 11) and low difficult goal group (LDG; n = 11). Both groups performed 15 trials in the pretest, 160 trials in the acquisition throughout four days, and 15 trials in the retention test after 72 hours. Performance was measured by means of the target bull’s-eye accuracy of the volleyball serve. Comparing the two groups' performance accuracy and consistency on pretest and retention tests was run through two-way ANOVA and ANCOVA (2 Groups x 2 Blocks). The results showed high goal led to greater performance accuracy in the retention than the lower goal, with a very large effect size. The HDG had higher accuracy in the retention test than the pretest (p < .001), while the LDG had no improvement. ANCOVA detected significant between the covariate perceived sport competence and tests. The effect size magnitude of the high goal difficulty in the serve accuracy was higher when adjusted by perceived sports competence. This finding indicates that perceived sports competence could maximize goal difficulty effectiveness. In conclusion, the goal with high difficulty is more effective for volleyball serve learning than low difficulty, and the perceived sports competence seems to moderate the learning process.
Perturbation analysis of subphase gas and meniscus curvature effects for longitudinal flows over superhydrophobic surfaces

Integral expressions for the first-order correction to the effective slip length for longitudinal flows over a unidirectional superhydrophobic surface with rectangular grooves are determined under the assumptions that the meniscus curvature is small and the viscosity contrast between the groove-trapped subphase gas and the working fluid is significant. Both pressure-driven channel flows and semi-infinite shear flows are considered. Reciprocity ideas, based on use of Green’s second identity, provide the integral expressions with integrands dependent on known flat-meniscus solutions found by Philip (Z. Angew. Math. Phys., vol. 23, 1972, pp. 353–372). The results extend earlier work by Sbragaglia & Prosperetti (Phys. Fluids, vol. 19, 2007, 043603) on how weak meniscus curvature affects hydrodynamic slip. In particular, we derive a new integral expression for the first-order slip length correction due to weak meniscus curvature.
MOESM5 of Testing the Coulomb stress triggering hypothesis for three recent megathrust earthquakes

We test the static Coulomb stress triggering hypothesis for three recent megathrust earthquakes (the 2004 Sumatra–Andaman earthquake, the 2010 Maule earthquake, and the 2011 Tohoku-Oki earthquake) using focal mechanism solutions for actual earthquakes as receiver faults to calculate Coulomb stress changes. For the 2004 Sumatra–Andaman and 2011 Tohoku-Oki earthquakes, the median values of the Coulomb stress changes for 100 consecutive earthquakes revealed temporal changes from approximately zero before the megathrust earthquake to significant positive values following the mainshock, followed by decay over time. Furthermore, the ratio of the number of positively to negatively stressed receiver faults increased after the megathrust. These results support the triggering hypothesis that the static stress changes imparted by megathrust earthquakes cause seismicity changes. This is in contrast to the results of a previous study that used optimally orientated receiver faults to calculate Coulomb stress changes, and this difference indicates the importance of considering the spatial and temporal heterogeneities of receiver fault distributions. For the 2010 Maule earthquake, however, the results are strongly dependent on fault-slip models. Since most receiver faults are concentrated in the mainshock source region, slip models significantly affect the computed Coulomb stress changes and sometimes cause anomalous stress concentrations along the edge of each sub-fault.
Implementation of HOTS Oriented Problem Solving in Elementary Social Studies Learning

The KTSP curriculum included in the 2013 curriculum as a complement to the previous curriculum is expected to change the perspective of educators in managing, planning and developing learning in the classroom. IPS learning. Student learning activities are not focused on finding a concept but rather on memorizing it, and book-based learning does not foster critical thinking skills. Therefore we need a Problem Solving learning model as a learning model that can help. students develop their Higher-Order Thinking Skills. The purpose of this research is to ascertain how social studies teaching in elementary schools incorporates HOTS-oriented problem solving. Qualitative literature review was conducted as a research method. Documentation study is a data collection technique, and involves examining the contents of documents related to the research subject. This research can be used as a reference for elementary school teachers to implement learning in their classes. As a result, teachers can use it to overcome learning challenges.

The biogeography of Gabonese savannas: Evidence from termite community richness and composition

The mosaic of savannas that persists in the forest‐dominant Congo Basin is thought to be palaeoclimatic relics, but past biogeographical processes that have formed and maintained these systems are poorly understood. Here, we explored the post‐Pleistocene biogeography of Gabon's savannas using termites as biological indicators to understand historical and mechanistic factors influencing present‐day termite communities in the country's extant savannas.
Pathomechanisms of Prenatally Programmed Adult Diseases

Based on epidemiological observations Barker et al. put forward the hypothesis/concept that an adverse intrauterine environment (involving an insufficient nutrient supply, chronic hypoxia, stress, and toxic substances) is an important risk factor for the development of chronic diseases later in life. The fetus responds to the unfavorable environment with adaptive reactions, which ensure survival in the short run, but at the expense of initiating pathological processes leading to adult diseases. In this review, the major mechanisms (including telomere dysfunction, epigenetic modifications, and cardiovascular–renal–endocrine–metabolic reactions) will be outlined, with a particular emphasis on the role of oxidative stress in the fetal origin of adult diseases.
Heavy Baryons with Strangeness

We apply the soliton description of baryons with a single heavy quark (charm or bottom). In this approach such baryons emerge as bound composites of a soliton of meson fields built from light quarks (up, down, strange) and a meson field that contains a heavy quark. We show that in this case the soliton must then be quantized as a diquark while the fermionic character arises from binding the heavy meson field. We are particularly interested in heavy baryons that have non-zero strangeness; in the quark model that corresponds to, say, up-strange-bottom (usb). Thus the flavor symmetry breaking among the light quarks must be fully incorporated when constructing diquark states. In the soliton model that symmetry breaking is parameterized by differences between the masses and decay constants of kaons and pions. Here we present computations of the diquark eigen-energies and eigen-functions that incorporates all orders of the light flavor symmetry breaking. We also compare these results to a leading order treatment of flavor symmetry breaking. The heavy meson couples according to the heavy spin-flavor symmetry to the chiral field that carries the soliton. In the background of the soliton the heavy meson field develop bound states. We compute the associated binding energies. These are the second major ingredient for our prediction of heavy quark baryons.
Bacteremia in Severe Mastitis of Dairy Cows

The aim of this cross-sectional study was to investigate the occurrence of bacteremia in severe mastitis cases of dairy cows. Milk and corresponding blood samples of 77 cases of severe mastitis were bacteriologically examined. All samples (milk and blood) were incubated aerobically and anaerobically to also investigate the role of obligate anaerobic microorganisms in addition to aerobic microorganisms in severe mastitis. Bacteremia occurred if identical bacterial strains were isolated from milk and blood samples of the same case. In addition, pathogen shedding was examined, and the data of animals and weather were collected to determine associated factors for the occurrence of bacteremia in severe mastitis. If Gram-negative bacteria were detected in milk samples, a Limulus test (detection of endotoxins) was also performed for corresponding blood samples without the growth of Gram-negative bacteria. In 74 cases (96.1%), microbial growth was detected in aerobically incubated milk samples. The most-frequently isolated bacteria in milk samples were Escherichia (E.) coli (48.9%), Streptococcus (S.) spp. (18.1%), and Klebsiella (K.) spp. (16%). Obligatory anaerobic microorganisms were not isolated. In 72 cases (93.5%) of the aerobically examined blood samples, microbial growth was detected. The most-frequently isolated pathogens in blood samples were non-aureus Staphylococci (NaS) (40.6%) and Bacillus spp. (12.3%). The Limulus test was positive for 60.5% of cases, which means a detection of endotoxins in most blood samples without the growth of Gram-negative bacteria. Bacteremia was confirmed in 12 cases (15.5%) for K. pneumoniae (5/12), E. coli (4/12), S. dysgalactiae (2/12), and S. uberis (1/12). The mortality rate (deceased or culled) was 66.6% for cases with bacteremia and 34.1% for cases without bacteremia. High pathogen shedding and high humidity were associated with the occurrence of bacteremia in severe mastitis.
The K\"ahler Quotient Resolution of C3/Γsingularities, the McKay correspondence and D=3 N=2 Chern-Simons gauge theories

We advocate that the generalized Kronheimer construction of the Kähler quotient crepant resolution Mζ −→ C3/Γ of an orbifold singularity where Γ ⊂ SU(3) is a finite subgroup naturally defines the field content and the interaction structure of a superconformal Chern-Simons Gauge Theory. This latter is supposedly the dual of an M2-brane solution of D = 11 supergravity with C×Mζ as transverse space. We illustrate and discuss many aspects of this type of constructions emphasizing that the equation p∧p = 0 which provides the Kähler analogue of the holomorphic sector in the hyperKähler moment map equations canonically defines the structure of a universal superpotential in the CS theory. Furthermore the kernel DΓ of the above equation can be described as the orbit with respect to a quiver Lie group GΓ of a special locus LΓ ⊂ HomΓ(Q⊗R,R) that has also a universal definition. We provide an extensive discussion of the relation between the coset manifold GΓ/FΓ, the gauge group FΓ being the maximal compact subgroup of the quiver group, the moment map equations and the first Chern classes of the so named tautological vector bundles that are in one-to-one correspondence with the nontrivial irreps of Γ. These first Chern classes are represented by (1,1)-forms on Mζ and provide a basis for the cohomology group H(Mζ ). We also discuss the relation with conjugacy classes of Γ and we provide the explicit construction of several examples emphasizing the role of a generalized McKay correspondence. The case of the ALE manifold resolution of C2/Γ singularities is utilized as a comparison term and new formulae related with the complex presentation of Gibbons-Hawking metrics are exhibited. ar X iv :1 71 0. 01 04 6v 4 [ he pth ] 2 0 M ay 2 01 8
A dynamic system for Gompertz model

ABSTRACT Two-parameter Gompertz distribution has been introduced as a lifetime model for reliability inference recently. In this paper, the Gompertz distribution is proposed for the baseline lifetimes of components in a composite system. In this composite system, failure of a component induces increased load on the surviving components and thus increases component hazard rate via a power-trend process. Point estimates of the composite system parameters are obtained by the method of maximum likelihood. Interval estimates of the baseline survival function are obtained by using the maximum-likelihood estimator via a bootstrap percentile method. Two parametric bootstrap procedures are proposed to test whether the hazard rate function changes with the number of failed components. Intensive simulations are carried out to evaluate the performance of the proposed estimation procedure.
Cortical activation during imagined walking for people with lower limb loss: a pilot study

Each year in Canada, a substantial number of adults undergo limb amputation, with lower limb amputation (LLA) the most prevalent. Enhancing walking ability is crucial for optimizing rehabilitation outcomes, promoting participation, and facilitating community reintegration. Overcoming challenges during the acute post-amputation phase and sub-acute rehabilitation necessitates alternative approaches, such as motor imagery and mental practice, to maximize rehabilitation success. However, the current evidence on activation patterns using motor imagery in individuals with LLA is limited. The primary objective was to assess the feasibility of observing brain activation during imagined walking in individuals with LLA utilizing 3T functional magnetic resonance imaging (fMRI). Eight individuals with LLA and 11 control subjects participated. Consistent with representations of the lower limbs, both control and amputee groups demonstrated bilateral activation in the medial surface of the primary motor and somatosensory cortices. However, individuals with lower limb amputations exhibited significantly greater activation during imagined walking, particularly in frontal regions and the medial surface of the primary motor and supplementary motor cortices. Furthermore, the volume of activation in the bilateral primary motor cortices was higher for participants with amputations compared to controls. The protocol developed in this study establishes a foundation for evaluating the effects of a gait training program that incorporates mental imagery alongside conventional rehabilitation practices, in contrast to standard care alone. This pilot investigation holds potential to enhance our understanding of brain plasticity in individuals with LLA and pave the way for more effective rehabilitation strategies to optimize functional recovery and community reintegration.
Development of a systematic, self-consistent algorithm for the K-DEMO steady-state operation scenario

An optimum plasma pressure/current density profile and corresponding heating/current drive (H/CD) determination scheme is newly developed by integrating equilibrium, stability, confinement, and H/CD, self-consistently subject to maximize the fusion gain for Korean fusion demonstration reactor (K-DEMO) steady-state operation scenarios. The integrated plasma modeling package, FASTRAN/IPS, is adopted for the integrated numerical apparatus. The target pressure profile with a pedestal structure is investigated by varying its peaking, pedestal height and width as a first step. Formation of stable equilibria is evaluated by solving the Grad–Shafranov equation and checking linear MHD stability. For the case of potentially stable equilibrium, required external heating distribution is calculated by considering both power balance and external current drive alignment to reproduce the pressure profile of the stable equilibrium. Electron/ion temperature and poloidal flux evolutions are solved with the derived heating configuration to find a steady-state scenario and achieve self-consistent plasma profiles. A self-consistent target steady-state pressure and current profile parameters are proposed through designed systematic algorithm with fusion power PF = 2070 MW, fusion gain Q = 19.7, and normalized beta βN = 2.8 at toroidal field BT = 7.4 T and plasma current IP = 15.5 MA. Feasibility of fusion power PF = 3000 MW operation is also explored with enhanced density and temperature limit assumption.
India's outward foreign direct investment: the home-country economic perspective

The paper examines the impact of home-country macroeconomic factors such as gross domestic product (GDP), money supply and inflation on the growth of outward foreign direct investment (OFDI) from India. Vector error correction model is employed to explore the long-run dynamics and short-run causality between the macroeconomic factors and OFDI for the period 1980-2014. The study finds that GDP has positive and significant impact on OFDI whereas money supply and inflation have significant but negative impact on it in the long-run. However, in the short-run, no causality is witnessed between OFDI and macroeconomic factors specified in the model.
The monogenic signal of potential-field data: A Python implementation

ABSTRACTWe have developed codes to calculate the local amplitude, the local phase, and the local orientation of the nonscale and the Poisson’s scale-space monogenic signals of potential-field data in version 1.0 of the open-source program Monogenic. The monogenic vector of a generic function is calculated in the wavenumber domain and then transformed back into the space domain to find the monogenic signal attributes. We compare the use of the nonscale monogenic signal with the Poisson’s scale-space monogenic signal in magnetic data. This comparison shows that the latter can produce better results as an edge detection filter. The implementation of the monogenic signal can be used to enhance other geophysical data, such as seismic, ground-penetrating radar, gravity, multiple-component gravity gradiometry, and magnetic gradient data.
A systematic review of Spanish academic production in the field of social work

Summary This article is a systematic review of the Spanish scientific production in social work hosted in the Web of Science. Findings The article analyzes the current state of social work research in Spain. Since the creation of the European Higher Education Area, Spanish social work has had to meet university research requirements, including the publication of papers in journals indexed in the world's leading databases. Spanish scientific production is analyzed from its beginnings until 2020. The main findings were that most of such research that was published by Spanish social work academic was in Spanish, while other categories of authors, such as nonsocial work Spanish academic, publish more in English. Spanish-language journals were mostly indexed in Emerging Sources Citation Index (ESCI), while those in English were in Journal Citation Reports (JCR) or Scopus, consistently receiving few citations. Women as main authors exceeded men in percentages of indexed articles. Bibliometric quality measures constructed with Scopus were slightly better than those with JCR. The most developed topics in the area were general and transversal issues such as immigration, social services, social intervention, and social policies. Applications The study demonstrates to Spanish social work researchers that they have greater likelihood of obtaining better quality indexes if they publish in English in JCR- and Scopus-indexed journals, resulting in enhanced academic career visibility.
