Probably the Best Itemsets

description: One of the main current challenges in itemset mining is to discover a small set of high-quality itemsets. In this paper we propose a new and general approach for measuring the quality of itemsets. The method is solidly founded in Bayesian statistics and decreases monotonically, allowing for efficient discovery of all interesting itemsets. The measure is defined by connecting statistical models and collections of itemsets. This allows us to score individual itemsets with the probability of them occuring in random models built on the data. As a concrete example of this framework we use exponential models. This class of models possesses many desirable properties. Most importantly, Occam's razor in Bayesian model selection provides a defence for the pattern explosion. As general exponential models are infeasible in practice, we use decomposable models; a large sub-class for which the measure is solvable. For the actual computation of the score we sample models from the posterior distribution using an MCMC approach. Experimentation on our method demonstrates the measure works in practice and results in interpretable and insightful itemsets for both synthetic and real-world data.

description: The course of 5 lectures given at the seminar "Integrable Systems: from Classical to Quantum" (Universite de Montreal, Jul 26 -- Aug 6, 1999) contains a detailed comment on the recently discovered (Gaudin-Pasquier, 1992) connection between Baecklund transformations in the theory of classical integrable systems on one hand, and Baxter's Q-operator for quantum integrable systems, on the other hand. We restrict our attention to the systems with finite number of degrees of freedom. Our main illustrative example is the periodic Toda lattice. We present a general construction of Q-operator for models governed by the SL(2)-invariant R-matrix and apply it to our example. We discuss also applications of BT and Q-operators to the separation of variables and theory of special functions.

description: Different disorders lead to various localization and topological phenomena in condensed matter and artificial systems. Here we study the topological and localization properties in one-dimensional Su-Schrieffer-Heeger model with spatially correlated random binary disorders. It is found that random binary disorders can induce the topological Anderson insulating phase from the trivial insulator in various parameter regions. The topological Anderson insulators are characterized by the disorder-averaged winding number and localized bulk states revealed by the inverse participation ratio in both real and momentum spaces. We show that the topological phase boundaries are consistent with the analytical results of the self-consistent Born approach and the localization length of zero-energy modes, and discuss how the bimodal probability affects the disorder-induced topological phases. The topological characters can be detected from the mean chiral displacement in atomic or photonic systems. Our work provides an extension of the topological Anderson insulators to the case of correlated disorders.

description: Information theory provides a spectrum of nonlinear methods capable of grasping an internal structure of a signal together with an insight into its complex nature. In this work, we discuss the usefulness of the selected entropy techniques for a description of the information carried by the surface electromyography signals during colorectal cancer treatment. The electrical activity of the external anal sphincter can serve as a potential source of knowledge of the actual state of the patient who underwent a common surgery for rectal cancer in the form of anterior or lower anterior resection. The calculation of Sample entropy parameters has been extended to multiple time scales in terms of the Multiscale Sample Entropy. The specific values of the entropy measures and their dependence on the time scales were analyzed with regard to the time elapsed since the operation, the type of surgical treatment and also the different depths of the rectum canal. The Mann Whithney U test and Anova Friedman statistics indicate the statistically significant differences among all of stages of treatment and for all consecutive depths of rectum area for the estimated Sample Entropy. The further analysis at the multiple time scales signify the substantial differences among compared stages of treatment in the group of patients who underwent the lower anterior resection.

description: Objective: This study assessed the psychometric properties of the Caring Efficacy Scale (CES) among personal care attendants providing care to older residents in residential aged care settings. Methods: This cross-sectional study was completed in Australia in 2020–2021. Confirmatory factor analysis (CFA) of the 30-item original CES (Model 1) and 28-item CES validated in registered nurses (Model 2) was conducted to assess the goodness of fit of these models in our study population. Due to unsatisfactory fit indices for both models, exploratory factor analysis (EFA) was conducted to examine the dimensionality and underlying structure of the original CES among personal care attendants. Internal consistency of the final scale and subscales identified was examined using item-total correlations and Cronbach's alpha coefficients. Results: Two hundred and eighty personal care attendants participated in the study. The model fit indices such as Comparative Fit Index and Tucker Lewis Index of both models were less than 0.90, while the Standardised Root Mean Square Residual and Root Mean Square of Approximation values were greater than or equal to 0.08 and 0.06, respectively. The EFA identified a two-factor structure, and 22 items of the 30 in the original scale were retained. Item-total correlations amongst items retained in the scale and subscales were greater than 0.3. Cronbach's alpha for the abbreviated scale was 0.85, with 0.83 and 0.79, respectively, for the two subscales. Conclusions: The modified CES can be used as a robust tool to assess the self-efficacy of personal care attendants in providing care to older residents in residential aged care settings.

description: Sunitinib, a multikinase inhibitor approved for a number of cancer indications has a low response rate. Identifying mechanisms of resistance could lead to rational combination regimens that could improve clinical outcomes. Here we report that resistance to sunitinib therapy was driven by autophagic degradation of TP53/p53. Deletion of ATG7 or ATG5 suppressed TP53 degradation, as did knockdown of SQSTM1/p62. Mechanistically, the transport of TP53 from the nucleus to the cytoplasm was essential for the sunitinib-induced autophagic degradation of TP53 and did not require TP53 nuclear export signals (NESs). Moreover, TP53 degradation was achieved by the transport of its nuclear binding target, HMGB1, which shifted TP53 from the nucleus to the cytoplasm. The inhibition of HMGB1 sensitized cancer cells to sunitinib. Importantly, sunitinib induced the degradation of all TP53 proteins, except for TP53 proteins with mutations in the interaction domain of TP53 with HMGB1 (amino acids 313 to 352). In conclusion, our data identify an alternative HMGB1-mediated TP53 protein turnover mechanism that participates in the resistance of sunitinib and suggest HMGB1 as a potential therapeutic target for improving clinical outcomes of sunitinib.

description: The rapid increase in obesity prevalence globally is posing a major epidemiological challenge to today’s healthcare systems. Obesity is responsible for 5% of all deaths with a global economic impact of approximately $2 trillion annually. Timely identification and quantification of excessive body fat plays a key role in having successful intervention programs. Visceral fat that is stored in the abdominal cavity and surrounds internal organs, in contrast to subcutaneous fat that is stored underneath the skin, is a marker of obesity-related diseases. Visceral fat causes inflammatory immune response causing damage to tissue and organs and is best quantified using medical imaging devices such as Computed Tomography (CT), Magnetic Resonance Imaging (MRI), or Dual-energy X-ray Absorptiometry (DXA). However, these devices are expensive, not always available, and are not suitable for large-scale epidemiological studies and community-wide screening. In this study, several linear, nonlinear, and ensemble machine learning regression models are developed to estimate visceral fat mass by using easy to obtain anthropometric measurements. Our methods are evaluated on 1,000 Qatar Biobank study participants and achieve adjusted coefficient of determination (R2) of 0.843 using a two-level stacked ensemble learning model. Waist circumference is identified as the feature of most importance for the estimation of visceral fat mass. In addition to estimating visceral fat mass, machine learning classification models are developed to evaluate the participants metabolic risk profile using visceral fat area thresholds. A linear Support Vector Machine (SVM) classifier achieves a recall of 90.1%. Using these models, clinicians and healthcare practitioners in Qatar will be able to perform initial screening for visceral obesity in a rapid, inexpensive, and noninvasive manner.

description: Identifying progenitor systems for the double-degenerate scenario is crucial to check the reliability of type Ia super-novae as cosmological standard candles. Santander-Garcia et al. (2015) claimed that Hen 2-428 has a double-degenerate core whose combined mass significantly exceeds the Chandrasekhar limit. Together with the short orbital period (4.2 hours), the authors concluded that the system should merge within a Hubble time triggering a type Ia supernova event. Garcia-Berro et al. (2016) explored alternative scenarios to explain the observational evidence, as the high mass conclusion is highly unlikely within predictions from stellar evolution theory. They conclude that the evidence supporting the supernova progenitor status of the system is premature. Here we present the first quantitative spectral analysis of Hen 2-428 which allows us to derive the effective temperatures, surface gravities and helium abundance of the two CSPNe based on state-of-the-art, non-LTE model atmospheres. These results provide constrains for further studies of this particularly interesting system.

description: We discuss the localization of wavefunctions along planes containing the shortest periodic orbits in a three-dimensional billiard system with axial symmetry. This model mimicks the self-consistent mean field of a heavy nucleus at deformations that occur characteristically during the fission process [1,2]. Many actinide nuclei become unstable against left-right asymmetric deformations, which results in asymmetric fragment mass distributions. Recently we have shown [3,4] that the onset of this asymmetry can be explained in the semiclassical periodic orbit theory by a few short periodic orbits lying in planes perpendicular to the symmetry axis. Presently we show that these orbits are surrounded by small islands of stability in an otherwise chaotic phase space, and that the wavefunctions of the diabatic quantum states that are most sensitive to the left-right asymmetry have their extrema in the same planes. An EBK quantization of the classical motion near these planes reproduces the exact eigenenergies of the diabatic quantum states surprisingly well.

description: The nature of the pseudogap phase of cuprates remains a major puzzle. Although there are indications that this phase breaks various symmetries, there is no consensus on its fundamental nature. Although Fermi-surface, transport and thermodynamic signatures of the pseudogap phase are reminiscent of a transition into a phase with antiferromagnetic order, there is no evidence for an associated long-range magnetic order. Here we report measurements of the thermal Hall conductivity $κ_{\rm xy}$ in the normal state of four different cuprates (Nd-LSCO, Eu-LSCO, LSCO, and Bi2201) and show that a large negative $κ_{\rm xy}$ signal is a property of the pseudogap phase, appearing with the onset of that phase at the critical doping $p^*$. Since it is not due to charge carriers -- as it persists when the material becomes an insulator, at low doping -- or magnons -- as it exists in the absence of magnetic order -- or phonons -- since skew scattering is very weak, we attribute this $κ_{\rm xy}$ signal to exotic neutral excitations, presumably with spin chirality. The thermal Hall conductivity in the pseudogap phase of cuprates is reminiscent of that found in insulators with spin-liquid states. In the Mott insulator LCO, it attains the highest known magnitude of any insulator.

Pricing under Fairness Concerns
Creators: name: Eyster, Erik
name: Madarasz, Kristof
name: Michaillat, Pascal
Publisher: name: Zenodo
Year: 2019

description: This paper proposes a theory of pricing consistent with two well-documented patterns: customers care about fairness, and firms take these concerns into account when they set prices. The theory assumes that customers find a price unfair when it carries a high markup over cost, and that customers dislike unfair prices. Since markups are not observable, customers must extract them from prices. The theory assumes that customers infer less than rationally: when a price rises after an increase in marginal cost, customers partially misattribute the higher price to a higher markup—which they find unfair. Firms anticipate this response and trim their price increases, which reduces the passthrough of marginal costs into prices below one: prices are somewhat rigid. Embedded in a New Keynesian model—as a replacement of Calvo pricing—our theory produces monetary nonneutrality. When monetary policy loosens and inflation rises, customers misperceive markups as higher and feel unfairly treated; firms mitigate the perceived unfairness of prices by reducing their markups, which in general equilibrium leads to higher output.

Without losing the generality, we consider the relaxation process for the two dimensional Ising and Potts model starting from an initial state with very high temperature and arbitrary magnetization. We confirm the generalized scaling form and observe that the critical characteristic functions of the initial magnetization for the Ising and the Potts model are quite different.

description: The non-classical features of quantum mechanics are reproduced using models constructed with a classical theory - general relativity. The inability to define complete initial data consistently and independently of future measurements, non-locality, and the non-Boolean logical structure are reproduced by these examples. The key feature of the models is the role of topology change. It is the breakdown of causal structure associated with topology change that leads to the apparently non-classical behaviour. For geons, topology change is required to describe the interaction of particles. It is therefore natural to regard topology change as an essential part of the measurement process. This leads to models in which the measurement imposes additional non-redundant boundary conditions. The initial state cannot be described independently of the measurement and there is a causal connection between the measurement and the initial state.

description: We introduce the simplest one-dimensional model of a dispersive optical medium with saturable dissipative nonlinearity and filtering (dispersive loss) which gives rise to stable solitary pulses (autosolitons). In the particular case when the dispersive loss is absent, the same model may also be interpreted as describing a stationary field in a planar optical waveguide with uniformly distributed saturable gain and absorption. In a certain region of the model's parameter space, two coexisting solitary-pulse solutions are found numerically, one of which may be stable. Solving the corresponding linearized eigenvalue problem, we identify stability borders for the solitary pulses in their parametric plane. Beyond one of the borders, the symmetric pulse is destroyed by asymmetric perturbations, and at the other border it undergoes a Hopf bifurcation, which may turn it into a breather.

Here, we report the results of new X-ray observations, taken between September 2017 and April 2018, with XMM-Newton, Chandra and Nicer. We derived a phase-connected timing solution yielding a frequency derivative of -9.26(6)x10^-14 Hz s-1. This value is consistent with that measured between 2009 and 2011, indicating that the pulsar spin-down rate remained quite stable during the long quiescent period. A spectral analysis of all the X-ray observations taken between 2009 and 2018 does not reveal significant spectral and/or flux variability. The spectrum of XTE J1810-197 can be described by the sum of two thermal components with temperatures of 0.15 and 0.3 keV, plus a power law component with photon index 0.6. We also found evidence for an absorption line at ~1.2 keV and width of 0.1 keV. Thanks to the long exposure time of the summed XMM-Newton observations, we could also carry out a phase-resolved spectral analysis for this source in quiescence. This showed that the flux modulation can be mainly ascribed to the the warmer of the two thermal components, whose flux varies by ~45 per cent along the pulse phase.

description: String theory can (in principle) describe gravity at all curvature scales, and can be applied to cosmology to look back in time beyond the Planck epoch. The duality symmetries of string theory suggest a cosmological picture in which the imprint of a primordial, pre-big bang phase could still be accessible to present observations. The predictive power of such a scenario relies, however, on our ability to connect in a smooth way the pre-big bang to the present cosmological regime. Classical radiation back reaction seems to play a key role to this purpose, by isotropizing and turning into a final expansion any state of anisotropic contraction possibly emerging from the pre-big bang at the string scale.

description: Calcein leakage assays are a standard experimental set-up for probing the extent of damage induced by external agents on synthetic lipid vesicles. The fluorescence signal associated with calcein release from liposomes is the signature of vesicle disruption, transient pore formation or vesicle fusion. This type of assay is widely used to test the membrane disruptive effect of biological macromolecules, such as proteins, antimicrobial peptides and RNA and is also used on synthetic nanoparticles with a polymer, metal or oxide core. Little is known about the effect that calcein and other fluorescent dyes may have on the properties of lipid bilayers, potentially altering their structure and permeability. Here we develop a coarse-grained model of calcein that is compatible with the Martini force field for lipids. We validate the model by comparing its dimerization free energy, aggregation behavior at different concentrations and interaction with a 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) membrane to those obtained at atomistic resolution. Our coarse-grained description of calcein makes it suitable for the simulation of large calcein-filled liposomes and of their interactions with external agents, allowing for a direct comparison between simulations and experimental liposome leakage assays.

description: The immune system plays a vital role against microbes and pathogens that threaten our health. As part of host defense, innate immune receptors, known as pattern recognition receptors (PRRs), sense different pathogen-associated molecular patterns (PAMPS) and Danger-associated molecular patterns (DAMPS), and initiate inflammation. Some PRRs trigger inflammation through a complex structure called the inflammasome. Several mutations in these receptors have been linked to different autoimmune and autoinflammatory disorders with variable clinical phenotypes. For example, patients with heterozygous gain of function mutations in the pyrin domain of NACHT, LRR, and PYD domains-containing protein 1 (NLRP1) present with multiple self-healing palmoplantar carcinoma ( MSPC) and dyskeratosis, but in a separate report, patients with biallelic mutations in the linker region of NLRP1 have an autoinflammatory disease with periodic fevers, arthritis, and dyskeratosis. In this paper, whole-genome sequencing detected novel compound heterozygous mutations in the seventh Leucine-rich repeat (LRR) domain and the “function-to-find” domain (FIIND) of NLRP1 in a patient presenting with a chronic urticarial rash. Sanger sequencing confirmed the mutations, and western blot revealed that NLRP1 protein is present in the patient and parents’ samples to a similar level as the healthy donor control. RNA sequencing identified differentially expressed genes in the patient compared to her healthy parents. The pathways in which these differentially expressed genes are involved have been studied as well to understand their connection with urticaria rash. This study presents new compound heterozygous mutations in different domains of NLRP1, which will facilitate a better understanding of the functions of these domains and their correlation with clinical phenotypes of the disease.

description: A system consisting of the cubic complex Ginzburg-Landau equation which is linearly coupled to an additional linear dissipative equation, is considered. The model was introduced earlier in the context of dual-core nonlinear optical fibers with one active and one passive cores. We argue that it may also possibly describe traveling-wave convection in a channel with an inner vertical partition. By means of systematic simulations, we find new types of stable localized excitations, which exist in the system in addition to the earlier found stationary pulses. The new localized excitations include pulses existing on top of a small-amplitude background (that may be regular or chaotic) {\em above} the threshold of instability of the zero solution, and breathers into which stationary pulses are transformed through a Hopf bifurcation below the zero-solution instability threshold. A sharp border between the stable stationary pulses and breathers, precluding their coexistence, is identified. Stable bound states of two breathers with a phase shift $π/2$ between their internal vibrations are found too. Above the threshold, the pulses are standing if the small-amplitude background oscillations are regular; if the background is chaotic, the pulses are randomly walking. With the increase of the system's size, more randomly walking pulses are spontaneously generated. The random walk of different pulses in a multi-pulse state is synchronized (but not completely) due to their mutual repulsion. At a large overcriticality, the multi-pulse state goes over into a spatiotemporal chaos.

description: The healing of wounds is the flagging concern in chronic wound cases especially when accompanied by pathogenic, diabetic comorbidities. Matrix metalloproteinases are associated with widespread pathological ailments, and the selective inhibitors for metalloproteinases can be of great interest in wound healing strategies. In the present research study, six constituents of Symplocos racemosa Roxb were evaluated for the docking aptitudes on human matrix metalloproteinase MMP 2 (PDB ID: 1QIB) and MMP 9 (PDB ID: 4H1Q) utilising Autodock Vina followed by the visualisation using Discovery studio (DS). The Pymol was used to generate the poses and the best binding pose was chosen for the docking aptitudes. 2D interactions and the 3D poses of the docked complex were accomplished using DS and LigPlot + software respectively. Working on SWISS ADME and OSIRIS software accomplished the physicochemical characteristics, absorption, distribution, metabolism, excretion, molecular properties, bioactivity score, and toxicity predictions. The molecule’s physiochemical investigations discovered that all of the ligands comply with Lipinski’s rule of five except compound 6, which deviated with two violations. Docking studies against 4H1Q revealed that compounds 1, 3, 5 and 6 exhibited maximum interactions with the target protein, with the free binding energies of −8.3 kJ Mol−1, −9.3 kJ Mol−1, −7.2 kJ Mol−1 and −11.0 kJ Mol−1 respectively. In case of the 1QIB target, compounds 1, 3 and 6 displayed remarkable binding energies of −8.7 kJ mol−1, −9.0 kJ mol−1 and −8.8 kJ mol−1. Bioactivity prediction study revealed that all of the selected Phytoconstituents displayed incredible Bioactivity scores. None of the selected chemical compounds was found to be irritant to the skin as discovered by toxicity studies. The contacts of the ligand-protein complex during the simulation studies revealed that the H-bond interactions of the ligands with LEU188, ALA189, GLN402, ARG420, MET422, PRO421, and ARG424 of 4H1Q were stable for more than 30% of the simulation time. It was thus concluded that the tested compounds predominantly compounds 1, 5 and 6 might rank among the vital supplementary lead drugs in chronic wounds and healing complexities. It is also worth noting the potential aptitude of the compound 3, however, its toxicity concern must be considered.

description: The maximum likelihood detection rule for a four-dimensional direct-detection optical front-end is derived. The four dimensions are two intensities and two differential phases. Three different signal processing algorithms, composed of symbol-by-symbol, sequence and successive detection, are discussed. To remedy dealing with special functions in the detection rules, an approximation for high signal-to-noise ratios (SNRs) is provided. Simulation results show that, despite the simpler structure of the successive algorithm, the resulting performance loss, in comparison with the other two algorithms, is negligible. For example, for an 8-ring/8-ary phase constellation, the complexity of detection reduces by a factor of 8, while the performance, in terms of the symbol error rate, degrades by 0.5 dB. It is shown that the high-SNR approximation is very accurate, even at low SNRs. The achievable rates for different constellations are computed and compared by the Monte Carlo method. For example, for a 4-ring/8-ary phase constellation, the achievable rate is 10 bits per channel use at an SNR of 25 dB, while by using an 8-ring/8-ary phase constellation and an error correcting code of rate 5/6, this rate is achieved at an SNR of 20 dB.

description: Excerpts from the report: During the past 5 years mechanical devices for sampling cotton bales during ginning have been installed in approximately 153 United States gins. Over 90 percent of the mechanical samplers are in Texas and California. The mechanical method of sampling, originally developed by researchers of the U. S. Department of Agriculture, was designed primarily to overcome the main shortcomings of the conventional method of cutting the bale. These shortcomings are the limited proportion of the individual bale represented by cut samples, the ragged appearance and surface contamination of the bales, and other disadvantages attributable to cutting holes in two sides of the bale. This study was made to provide information helpful in evaluating the two methods of sampling and in recognizing and overcoming barriers to the wider use of mechanical sampling. The information was obtained mainly during 1958 and 1959 by personal interview and by mail questionnaire from representatives of the domestic cotton industry, sampler manufacturers, and others with experience relating to both mechanical and conventional sampling.

description: To understand the biodiversity of an ecosystem cannot be understood by solely analyzing the pair relations of competing species. Instead, we should consider multi-point interactions because the presence of a third party could change the original microscopic outcome significantly. In this way an alliance may emerge where species, who may have biased relations otherwise, can protect each other from an external invader. Such an alliance can be formed by two, three or even more species. By introducing a minimal model where six species compete for space we here study how the size of an alliance determines the vitality of a formation. We show that in the majority of parameter space the group of the smallest size prevails and other solutions can only be observed in a limited parameter range. These phases are separated by discontinuous phase transitions which can only be identified by intensive numerical efforts due to serious finite size effects and long relaxation processes.
