Process Mining in Cardiology: A Literature Review

Process mining is a data analytics approach which has shown promising results in healthcare including the potential to improve the management of chronic diseases such as cardiovascular disease (CVD). CVD are one of the leading causes of premature death worldwide. Helping healthcare professionals develop a better understanding of how to improve CVD care pathways may result in better outcomes for patients. This paper describes the opportunities for process mining to support such improvements and provides a summary of process mining studies undertaken in the field of cardiology. The initial search found 1,597 potentially relevant papers which, after a systematic review, identified a final set of 32 relevant studies. These studies were analyzed across five themes: process and data types; research questions; techniques, perspective and tools; methodologies; limitations and suggested future work.
Replication in Experimental Economics: A Historical and Quantitative Approach Focused on Public Good Game Experiments

We propose a historical perspective on replication in experimental economics focused on public good games. Our intended contribution is twofold: in terms of method and in terms of object. Methodologically, we blend traditional qualitative history of economics with a less traditional quantitative approach using basic econometric tools to detect unnoticed historical patterns of replication. In terms of our object, we highlight a type of replication that we call " baseline replication " , which is not present in explicit methodological discussions, yet central in the specificity of experimental economics regarding replication in economics.

Unsupervised clustering of audio data for acoustic modelling in automatic speech recognition systems

This thesis presents a system that is designed to replace the manual process of generating a pronunciation dictionary for use in automatic speech recognition. The proposed system has several stages. The first stage segments the audio into what will be known as the subword units, using a frequency domain method. In the second stage, dynamic time warping is used to determine the similarity between the segments of each possible pair of these acoustic segments. These similarities are used to cluster similar acoustic segments into acoustic clusters. The final stage derives a pronunciation dictionary from the orthography of the training data and corresponding sequence of acoustic clusters. This process begins with an initial mapping between words and their sequence of clusters, established by Viterbi alignment with the orthographic transcription. The dictionary is refined iteratively by pruning redundant mappings, hidden Markov model estimation and Viterbi re-alignment in each iteration. This approach is evaluated experimentally by applying it to two subsets of the TIMIT corpus. It is found that, when test words are repeated often in the training material, the approach leads to a system whose accuracy is almost as good as one trained using the phonetic transcriptions. When test words are not repeated often in the training set, the proposed approach leads to better results than those achieved using the phonetic transcriptions, although the recognition is poor overall in this case.
VIBRATIONS IN BUILDINGS DUE TO RAILWAY TRAFFIC IN TUNNELS: MODELLING STRATEGIES AND INFLUENCE OF SOIL STIFFNESS

Abstract. In this paper a numerical study about the influence of soil stiffness on the assessment of vibrations induced by railway traffic in tunnels is performed. A comprehensive numerical model is used to achieve the lumped objective, where the source of vibration (traintrack interaction), the propagation of vibrations (tunnel-ground system) and their reception (building close to the railway infrastructure) are simulated by a sub-structuring approach. It was found that the soil stiffness plays a relevant role on the mechanisms of propagation of vibrations through the ground as well as on the soil-structure interaction. Regarding the last topic, different approaches were attended for the inclusion of the SSI effects, namely a detailed boundary elements formulation and a simplified lumped-parameter model. The study performed revealed that the usage of lumped parameter models can be faced as a good option taking into account the compromise between accuracy of the solution and reduction of the computation effort.
Thermal behavior of PCM containing walls: a time series model based on cointegrated processes and conditional heteroskedasticity

The two main advantages deriving from the insertion of Phase Change Materials (PCM) inside the external envelopes of buildings are lowering temperature peaks in internal environments and shifting their occurrence in time. In this contribution the data collected from a three-month experimental campaign are elaborated through a time series model with conditional heteroskedasticity, for the evaluation of the positive effects deriving from the insertion of a PCM layer in standard stratifications of dry assembled lightweight walls. In this work the performances of two different PCM containing stratifications are compared with the ones of a standard dry assembled lightweight wall. The statistical model in this paper is able of interpreting the long memory effects that affect the temperature time series of the experimental walls, even if with the use of a small number of parameters.

On Canonical-type Connections on Almost Contact Complex Riemannian Manifolds

We consider a pair of smooth manifolds, which are the counterparts in the even-dimensional and odd-dimensional cases. They are separately an almost complex manifold with Norden metric and an almost contact manifolds with B-metric, respectively. They can be combined as the so-called almost contact complex Riemannian manifold. This paper is a survey with additions of results on differential geometry of canonical-type connections (i.e. metric connections with torsion satisfying a certain algebraic identity) on the considered manifolds.
Fabrication and Evaluation of Pt/M (M= Co, Fe) Chitosan Supported Catalysts for Methanol Electrooxidation: Application in Direct Alcohol Fuel Cell

In this work, Pt, Fe and Co nanoparticles were prepared by chemical reduction of the metal salts in chitosan as the support. NaBH4 was used as the reducing agent Pt-Fe, Pt-Co and Pt-Fe-Co-chitosan nanocomposites were synthesized and characterized by UV–Vis spectra and Transmission electron microscopy images. GC/Pt-chitosan, GC/Pt-Co-chitosan, GC/Pt-Fe-chitosan and GC/Pt-Co-Fe-chitosan electrodes were prepared. The performances of these electrodes for methanol electrooxidation were investigated through cyclic voltammetric and chronoamperometric curves. The effect of some experimental factors such as the amounts of Fe and Co nanoparticles dispersed in chitosan, methanol concentration and scan rate were studied and the optimum conditions were determined. The effect of temperature was also investigated and the activation energies were calculated. The performance of Pt-Fe-Co-chitosan nanocomposites was determined in a direct methanol fuel cell in different conditions. The electrochemical and fuel cell measurements showed that Pt-Fe-Co-chitosan nanocatalyst has the best activity for electrooxidation of methanol among all different compositions electrodes.
The psychological dynamics: the mechanism of the need for psychological stimulation

The paper sets to identify forms of the need for psychological stimulation which satisfy the invariance group of the partial differential equation: ∂2u/∂t-2=(ot+p)2/4[∂2u/∂m2+∂2u/∂v2+∂2u/∂b2]+Vu The equation describes the tensional state (u) function in physical time (t), the ratio between the current neuropsychological activation and the minimal one needed for the activation of attention (m), apperception (v), amplitude of the tensional state (b) and need for psychological stimulation (V). We associate the need for psychological stimulation with an unused potential of the tensional state. Complex calculations led to a constant unused potential! The result proves that the source of the need for psychological stimulation is the unconscious instance.
A COMPREHENSIVE STUDY ON THE NATURAL PLANT PHENOLS: PERCEPTION TO CURRENT SCENARIO

Phenolic compounds are secondary metabolites of plants that are widely distributed throughout the plant kingdom. Secondary metabolites possess structural diversity that provide flavor and color to fruits, vegetables, and grains. They precipitate various pharmacological and toxicological effects on living beings. Extraction of the bioactive plant constituents has always been a challenging task for the researchers. In the present study, an attempt has been made to give an overview on chemistry, distribution, extraction and isolation techniques of various plant phenolics.
ESTIMATION OF THE WANDA GLACIER (SOUTH SHETLANDS) SEDIMENT EROSION RATE USING NUMERICAL MODELLING

Glacial sediment yield results from glacial erosion and is influenced by several factors including glacial retreat rate, ice flow velocity and thermal regime. This paper estimates the contemporary subglacial erosion rate and sediment yield of Wanda Glacier (King George Island, South Shetlands). This work also examines basal sediment evacuation mechanisms by runoff and glacial erosion processes during the subglacial transport. This is small temperate glacier that has seen retreating for the last decades. In this work, we examine basal sediment evacuation mechanisms by runoff and analyze glacial erosion processes occurring during subglacial transport. The glacial erosion rate at Wanda Glacier, estimated using a numerical model that consider sediment evacuated to outlet streams, ice flow velocity, ice thickness and glacier area, is 1.1 ton m yr -1 .
Wheel/rail rolling noise: the effects of non-linearities in the contact zone

Models that have been developed for wheel/rail rolling noise are generally linear in order to make use of a frequency-domain approach. In fact, the local elasticity between the wheel and the rail exhibits a nonlinear stiffness behaviour due to geometrical effects. This is, therefore, usually linearised about a nominal static preload. For large defects on the wheel or rail surface, however, such an approach can no longer be used and a time-domain solution including the non-linearities is required. By using simplified models of the wheel and rail dynamics in such a timestepping model, the effects of the non-linearities have been determined. It has been found that, for normal levels of surface roughness found on wheels and rails, the linear models give a satisfactory prediction. However, for larger defects, such as wheel flats or rail joints, the non-linear effects are found to be significant. A hybrid approach is used to predict the noise radiation due to such defects, for which more detailed dynamic models should be incorporated. The contact force from the nonlinear calculation is converted back to an equivalent roughness that can be used in a linear model for the response and noise radiation.

Classification Accuracy improvements by the use of simultaneous biometric measurements: Hand palm recognition

Biometric systems can achieve good results on their own. Sometimes, the single use of one biometric feature does not suit properly the application requirements because of the fact that the security level has to be extremely high. To achieve this requirement, it is possible to use a multimodal biometric system. This implies that the user must pass through a set of biometric devices to login in each one. This process could be sometimes overwhelming for the users and, for this reason, a new multimodal hand-palmprint identification device is proposed. Within this approach, the acquisition of the different biometric measures is done at the same time.
Application of current in situ hybridization techniques for grape phylloxera ( Daktulosphaira vitifoliae , Fitch) and grapevine ( Vitis spp. L.)

In situ hybridization and in situ PCR directly localize specific DNA and RNA sequences in tissues. To exactly focus on the processes occurring on cell- or tissue level, in situ techniques can be efficiently employed. Recent advances in viticultural research in the fields of genomics, proteomics and metabolomics are likely to employ these techniques to link DNA- or mRNA sequence information to physiological traits and processes occurring in the grapevine. In this paper, we present a range of possibilities for in situ techniques that can be applied in grapevine research. Two examples covering in situ PCR of grapevine roots and in situ hybridization of grape phylloxera will be given for illustration. Moreover, key steps of the techniques are discussed, which may be helpful to researchers aiming to employ in situ hybridization or in situ PCR.
Framework for Hyperspectral Image Segmentation using Unsupervised Algorithm

Hyperspectral imaging system contains stack of images collected from the sensor with different wavelengths representing the same scene on the earth. This paper presents a framework for hyperspectral image segmentation using a clustering algorithm. The framework consists of four stages in segmenting a hyperspectral data set. In the first stage, filtering is done to remove noise in image bands. Second stage consists of dimensionality reduction algorithms, in which the bands that convey less information or redundant data will be removed. This deletion will decrease the storage requirement, computational load etc in processing the hyperspectral data. In the third stage, the informative bands which are selected in the second stage are merged into a single image using hierarchical fusion technique. The main goal of image fusion is to combine all the information from the selected image bands to form a single image. This single image is segmented using Fuzzy C-means (FCM) algorithm. The qualitative and quantitative analysis shows that this framework will segment the data set more accurately by combining all the features in the image bands.
Schumpeter and the revival of evolutionary economics: an appraisal of the literature

Abstract. During the last two decades we have seen a revival of interest in the works of Joseph Schumpeter and “evolutionary” ideas in economics more generally. A professional society honouring Schumpeter's name has been founded, and linked to it we have had for more than fifteen years now a professional journal devoted to this stream of thought. However, it has been argued that, despite these developments, the link between Schumpeter's own work and the more recent contributions to evolutionary economics is in fact rather weak. This paper considers this claim. Based on an analysis of Schumpeter's contribution to economics the paper presents an overview and assessment of the more recent literature in this area. It is argued that although there are important differences between Schumpeter's work and some of the more recent contributions, there nevertheless remains a strong common core that clearly distinguishes the evolutionary stream from other approaches (such as, for instance, so-called “new growth theory”).
Analysis of indicators of osteogenesis, cytotoxicity and genotoxicity of an experimental β-TCP compared to other bone substitutes

The aim of this study was to evaluate the indicators of osteogenesis, cytotoxicity and genotoxicity of an experimental beta tri-calcium phosphate (experimental β-TCP) compared with two other bone substitutes: bovine hydroxyapatite (HA) (Bio-Oss ® - Geistlich) and beta tri-calcium phosphate (β-TCP - Bionnovation). The cell viability and genotoxicity were measured by MTT and MNT assay, respectively. The indicators of osteogenesis were analyzed by alkaline phosphatase activity, total protein content, and calcium deposition. The MTT and MNT assay showed that none of the tested materials was cytotoxic nor genotoxic. Concerning the indicators of osteogenesis, it was observed that cells in contact with all the materials were able to induce the osteogenesis and this process was influenced by the period of the cell culture in contact with bone substitutes. Based on the results of this study, it was concluded that this experimental β-TCP appears to be a promising material as a bone substitute.
The Future of Private Equity in Europe – the Determinants Across Countries

This paper examines two aspects related to private equity investments in Europe. First, we will present the evolution of private equity investments across European countries during the last crisis. Second, the paper will analyse and identify the main determinants of the European private equity market, using an empirical panel analysis. The empirical model includes many of the determinants already tested in previous studies (GDP growth, Market Capitalization, Research and Development Expenditures, Interest rates, etc.) and also new variables such as productivity and corruption index which we consider important factors in explaining the evolution of private equity investments in Europe. The present research paper follows the equilibrium model of private equity investments (Gompers and Lerner 1998, Jeng and Wells 2000, Romain and de La Potteria 2004, Felix 2007). We will use aggregated data from European private equity market during 2000-2013, as well as macroeconomic data, in order to estimate a panel data model with fixed and random effects. This paper will also run the Hausman specification test in order to compare the consistency of fixed effects models and random effects models. Our results confirm existent hypotheses regarding the importance of some determinants on the evolution of private equity investments in Europe. However, in the context of the last crisis new factors emerged as important for the private equity market in Europe such as productivity or corruption.
SETTLEMENT MEASUREMENTS OPTIMISING CONSTRUCTION OF A BREAKWATER ON SOFT SOIL

The need of an improved harbour access resulted into the construction of two new rubble mound breakwaters in Ostend, Belgium (Verhaeghe et al., 2010). Extensive soil investigation during the design phase of the breakwaters showed that the most northern part of the western breakwater is located in a zone containing a thick upper layer of soft material. To deal with the bad soil characteristics, a very strong geotextile was used to serve as a kind of armouring of the breakwater. An extensive analysis was carried out to determine how fast construction could go on, avoiding overall geotechnical failing, and to determine the settlements to be expected. During construction of the western breakwater, extensive settlement measurements were performed. This paper describes the settlement calculations performed with Plaxis2D versus the settlement measurements performed on site, leading to an optimised phasing of the construction works.
Indeterminate Equilibria in New Keynesian DSGE Model: An Application to the US Great Moderation

This paper tests “Bad Policy” Hypothesis which refers to the Great Moderation in the US. We examine this hypothesis by simulating model based impulse response functions for the both pre-Volcker period and post 1982 period. Deriving and simulating standard New Keynesian DSGE Model explicitly, we find that while post 1982 policy i.e. active policy, is consistent with the unique stable equilibrium characteristics; pre-Volcker or passive monetary policy generates equilibrium indeterminacy. Moreover, our simulated-impulse response functions show that the response of inflation and the output gap in post 82 period is weaker than the macroeconomic responses of the pre-Volcker period.
High dimensional k NN-graph construction using space filling curves

The k nearest neighbor (kNN) graph has an important role in many computer science fields including machine learning and data mining. Although many fast methods exist for constructing kNN graph for low dimensional data, it is still an open question how to do it efficiently in high dimensional cases. We present a new method to construct approximate kNN graph for medium to high dimensional data. Our method uses space filling curves to construct initial graph and then continues to improve this using neighborhood propagation. It is targeted for Euclidean distance metric but has potential to be applied for general Minkowski distance metrics. Experiments show that the method is faster than compared methods with three different benchmark data sets which dimensionality ranges from 14 to 544.
Falls and Physical Performance among Frail Sexagenarians and Septuagenarians

Background: In Malaysia, there are few populationbased studies on the factors associated with falls, and there is a lack of prevention of falls among older adults in primary and secondary health care, particularly in terms of physical activity that could improve the physical performance of individuals at risk of falling. Therefore, the objective of the present study was to determine the relationship between physical performance, the number of falls and the sociodemographic, physical, clinical and functional characteristics of older adult fallers. Methods: Crosssectional study carried out among 72 older adults with a history of falls in the past year, 65.3% of which were women. The participants received care at the geriatric outpatient clinic and divided into the following groups: worst physical performance (WPP) and best physical performance (BPP), onetime fallers (1F) and frequent fallers (2F). Sociodemographic, clinical, physical and functional characteristics were considered as independent variables. Comparison analysis between the groups was conducted. Results: The WPP group was older and had a higher number of illnesses and less independence in most motor dimension tasks compared to the BPP group. The 2F group had a higher number of illnesses, less handgrip strength and less independence in the bowel management task in the motor dimension of the Functional Independence Measure (FIM) compared to the 1F group. Conclusions: Among older adults fallers, poor physical performance is associated with more advanced age, more illnesses and less functional independence. Moreover, recurrent falls are associated with more illnesses, less muscle strength and less functional independence in the bowel management task.
