Novel feature selection methods for high dimensional data

La seleccion de caracteristicas se define como el proceso de detectar las caracteristicas relevantes y descartar las irrelevantes, con el objetivo de obtener un subconjunto de caracteristicas mas pequeno que describa adecuadamente el problema dado con una degradacion minima o incluso con una mejora del rendimiento. Con la llegada de los conjuntos de alta dimension -tanto en muestras como en caracteristicas-, se ha vuelto indispensable la identificacion adecuada de las caracteristicas relevantes en escenarios del mundo real. En este contexto, los diferentes metodos disponibles se encuentran con un nuevo reto en cuanto a aplicabilidad y escalabilidad. Ademas, es necesario desarrollar nuevos metodos que tengan en cuenta estas particularidades de la alta dimension. Esta tesis esta dedicada a la investigacion en seleccion de caracteristicas y a su aplicacion a datos reales de alta dimension. La primera parte de este trabajo trata del analisis de los metodos de seleccion de caracteristicas existentes, para comprobar su idoneidad frente a diferentes retos y para poder proporcionar nuevos resultados a los investigadores de seleccion de caracteristicas. Para esto, se han aplicado las tecnicas mas populares a problemas reales, con el objetivo de obtener no solo mejoras en rendimiento sino tambien para permitir su aplicacion en tiempo real. Ademas de la eficiencia, la escalabilidad tambien es un aspecto critico en aplicaciones de gran escala. La eficacia de los metodos de seleccion de caracteristicas puede verse significativamente degradada, si no totalmente inaplicable, cuando el tamano de los datos se incrementa continuamente. Por este motivo, la escalabilidad de los metodos de seleccion de caracteristicas tambien debe ser analizada. Tras llevar a cabo un analisis en profundidad de los metodos de seleccion de caracteristicas existentes, la segunda parte de esta tesis se centra en el desarrollo de nuevas tecnicas. Debido a que la mayoria de metodos de seleccion existentes necesitan que los datos sean discretos, la primera aproximacion propuesta consiste en la combinacion de un discretizador, un filtro y un clasificador, obteniendo resultados prometedores en escenarios diferentes. En un intento de introducir diversidad, la segunda propuesta trata de usar un conjunto de filtros en lugar de uno solo, con el objetivo de liberar al usuario de tener que decidir que tecnica es la mas adecuada para un problema dado. La tercera tecnica propuesta en esta tesis no solo considera la relevancia de las caracteristicas sino tambien su coste asociado -economico o en cuanto a tiempo de ejecucion-, por lo que se presenta una metodologia general para seleccion de caracteristicas basada en coste. Por ultimo, se proponen varias estrategias para distribuir y paralelizar la seleccion de caracteristicas, ya que transformar un problema de gran escala en varios problemas de pequena escala puede llevar a mejoras en el tiempo de procesado y, en algunas ocasiones, en precision de clasificacion.
Prevalence of Oculomycosis in a Tertiary Care Centre

Objectives: The present study was undertaken to investigate the prevalence of mycotic keratitis among clinically diagnosed cases of ulcerative keratitis attending ophthalmic OPD & admitted in ward of Shri Chhatrapati Shivaji Maharaj General Hospital, Solapur from Jan 2005 to Dec 2005. Background: Mycotic keratitis has emerged to be a major ophthalmic problem since its recognition in 1879, especially in subtropical & tropical climates. Method: The patients diagnosed clinically as minor corneal abrasion, healed corneal ulcer or corneal opacity with no signs of infection was not included in this study. The corneal scrapings were processed for bacteriological and mycological examination. The material was subjected to 10% KOH mount & cultured on Sabouraud dextrose agar with & without antibiotics. Result: Out of 74 samples, 13 (17.56%) revealed hyphae in direct KOH mount and 25 (33.78%) showed fungal culture positive. Among the fungal isolates, Aspergillus was more prevalent (18.91%) followed by Fusarium spp. (5.4%) and Curvularia spp. (2.7%). Among the rare fungi causing mycotic keratitits one isolate each of Exserohilum rostratum, Colletotrichum gloeosporiodes, Bipolaris spicifera & Rhodotorula rubra were isolated in the present study.Out of 74 cases, agricultural workers 32 (43.24%) formed the major occupational group i.e.32 (43.24%) as they are more prone to trauma by vegetative matter. Conclusion: The bacteriological and mycological examination of keratitis is definitely contributory for specific management and to save the vision of the patients.
Budget accuracy in Czech municipalities and the determinants of tax revenue forecasting errors

This paper evaluates the accuracy of municipal budgets and their major components and explores the factors influencing tax revenue forecasting errors in municipalities with extended scope between 2002 and 2011 using the generalised method of moments. Tax forecasting errors are influenced by the economic situation and structure of tax revenue. Higher underestimation is observed in municipalities with incremental revenue forecasting. The impact of political factors is quite strong: municipalities with more fragmented municipal councils approve more optimistic tax revenue forecasts and forecasts are more optimistic in election years.
Distribution of apolipoprotein E gene polymorphism in students and in high-educated elderly from Serbia

Apolipoprotein E (ApoE) play important role in lipid metabolism and in processes of remodeling and reparation in central nervous system. Three common ApoE isoforms, ApoE2, ApoE3 and ApoE4, show strong genetic determination by e2, e3, and e4 allele. In human genome gene encoding Apolipoprotein E (APOE) is located on cromosome 19, and e2/e3/e4 haplotype system is defined by 2 non-synonymous single nucleotide polymorphisms (SNPs) in the APOE exon 4. The frequency of the three APOE alleles and corresponding genotypes varies across human populations, with possible clinical implications. At least, variable distribution of e4 allele may contribute to the regional risk of cardiovascular and Alzheimer’s diseases. Allele-frequency comparisons between younger and older populations suggest an effect of APOE on mortality, but these data are not consistently confirmed. In the present study we have analyzed the distribution of APOE gene polymorphism in a group of University students and retained University professors living in Serbia. After DNA extraction from peripheral blood samples, the APOE genotype was determined by polymerase chain reaction (PCR) followed with HhaI restriction digestion. We found no statistically significant difference in alleles and genotypes distribution between younger and elder group of participants. Also, there was no significant difference compared to APOE data previously obtained in YUSAD cohort of healthy school children (15 y of age) from different regions of Serbia. In both of our groups, as well as in YUSAD cohort, frequency of APOE e4 allele was <10%. The observed frequencies are lower than in neighboring countries, but similar with Spanish data and some Asian populations. Our results do not support important role of APOE e4 in the morbidity and mortality in Serbian population, but gene-environmental-social interactions should be considered.

A Case-Series of Solitary Skull Neoplastic Lesions Treated with En-Block Resection and Complex Cranioplasty

Background and aims: Tumors involving the calvarium but extending into the adjacent scalp layers and/or the underlying dura and brain are technically challenging to treat. Patients often present late in the course of disease which results in either irresectable tumor configurations or – if at all feasiblethe need for complex resections, the latter involving allograft cranioplasty and duraplasty sometimes in combination with skin grafting to repair surgical defects. This multidisciplinary study evaluates the outcome of complex single stage resections treated with allograft cranioplasty and duraplasty some of which required a combination of same-session soft tissue coverage by plastic surgery. Methods: We analyzed the management of 17 such complex cases, including 11 patients with metastases secondary to primary malignancies, 2 cases of meningiomas as well as single cases of squamous cell carcinoma, sarcoma, epidermoid and hemangioma. All patients underwent single step tumor resection craniectomy repaired with cranioplasty/duraplasty using a titanium mesh which was augmented by methyl methacrylate. Closure ensued with or without soft tissue coverage by flaps and/or grafts. Multidisciplinary follow-up was pursued to monitor local recurrence and potential wound complications. Results: Outcome analysis revealed excellent results without wound complications or local recurrence and short hospital stay following the procedure. Conclusion: Single step en-bloc resection of complex skull lesions with same-session cranioplasty may be an effective option to manage patients with solitary skull tumors whether benign, primary malignant or secondary malignant.
Leaf Gas Exchange and Damage from Adult D . abbreviatus 655 LEAF GAS EXCHANGE AND DAMAGE OF MAHOGANY AND POND APPLE TREES FROM ADULT DIAPREPES ABBREVIATUS ( COLEOPTERA : CURCULIONIDAE ) FEEDING AND SOIL FLOODING

The effects of feeding on leaves by adult Diaprepes root weevil, Diaprepes abbreviatus L. (Coleoptera: Curculionidae), and flooding on leaf gas exchange [net CO 2 assimilation ( A ), transpiration ( E ), and stomatal conductance ( g s )], plant growth (root, stem, leaf, and total plant dry weights, stem diameter, and plant height) and adult host plant preference (feeding damage and oviposition) were determined on mahogany, Swietenia mahagoni Jacq. , and pond apple, Annona glabra L. , trees in outdoor screen cages. Flooding reduced leaf gas exchange, plant growth, and D. abbreviatus feeding damage of mahogany trees. Leaf gas exchange of infested and non-infested trees of both mahogany and pond apple were similar except for one measurement date for mahogany. Leaf dry weights were greater for non-infested than infested mahogany trees. There was no effect of infestation on dry weights of pond apple trees. Based on feeding injury to leaves, adults preferred non-flooded to flooded mahogany trees. The lack of response in leaf damage or oviposition to flooding for pond apple was attributable to the avoidance of leaves by adult D. abbreviatus of this plant species despite it being a host for root weevil larvae. The results indicate that while flooding of the root zone adversely affects growth and physiology of mahogany trees, it does not predispose trees to greater damage from adult D. abbreviatus . In fact, adult insect damage was greater for non-flooded than flooded trees. Pond apple was not greatly affected by root zone flooding and was not a preferred host of adult D. abbreviatus under flooded or non-flooded conditions.
Flutter of long flexible cylinders in axial flow

We consider the stability of a thin flexible cylinder considered as a beam, when subjected to axial flow and fixed at the upstream end only. A linear stability analysis of transverse motion aims at determining the risk of flutter as a function of the governing control parameters such as the flow velocity or the length of the cylinder. Stability is analysed applying a finite-difference scheme in space to the equation of motion expressed in the frequency domain. It is found that, contrary to previous predictions based on simplified theories, flutter may exist for very long cylinders, provided that the free downstream end of the cylinder is well-streamlined. More generally, a limit regime is found where the length of the cylinder does not affect the characteristics of the instability, and the deformation is confined to a finite region close to the downstream end. These results are found complementary to solutions derived for shorter cylinders and are confirmed by linear and nonlinear computations using a Galerkin method. A link is established to similar results on long hanging cantilevered systems with internal or external flow. The limit case of vanishing bending stiffness, where the cylinder is modelled as a string, is analysed and related to previous results. Comparison is also made to existing experimental data, and a simple model for the behaviour of long cylinders is proposed.
Bubble Sizing by Interferometric Laser Imaging

The objective of the present contribution is to establish a novel measurement technique for velocity and diameter of transparent spherical gas bubbles in order to obtain such important information as mass transfer rate at the interface of gas-liquid phases, or drag coefficient of the rising bubbles in liquid. This technique gives spatial distribution of velocity and diameter of bubbles simultaneously by capturing the sequential images of fringes by using a pulsed Nd:YAG laser source and a high resolution CCD camera. Figure 1 is a snapshot of the circular interferometric pattern generated by external reflection(p 0) and direct refraction(p1) lights from the transparent spherical bubble from a nozzle of 60 m in diameter. This figure shows the difference of the diameter by counting the number of fringes or fringe spacing. Additionally, continuous acquisition of the image sequence enables us to know the velocity of individual bubbles by tracking their movement. Figure 2 illustrates the simplified experimental setup for the rising bubbles, including the flow field and optical equipment. The results of the gas dissolution measurement of spherical CO2 bubbles into a stationary fluid show a range of measured bubble diameters of approximately 100 m to 1000 m with rising velocities up to 30mm/s. Smaller Bubble d=160μm Larger Bubble d=450μm Figure 1: Comparison of the fringe images of bubbles of different diameter. Pulsed Nd:YAG Laser Cylindrical Lens
Anger rumination in Australia and Spain: Validation of the Anger Rumination Scale

Objective Rumination has been empirically supported in the experience of anger. The Anger Rumination Scale ( ARS ) was developed to assess ruminative processes in anger. The aim of this study was to evaluate the psychometric properties of the ARS in Australia and Spain. Method A large non‐clinical sample (N = 1,752) completed a battery including the ARS and measures of trait anger, anger expression and control, aggression, emotional symptoms, and emotion regulation strategies, to determine the factor structure, validity, and reliability of the ARS. Variations between the two cultural samples were also analysed. Results Confirmatory factor analysis verified the four‐factor structure of Angry Memories, Thoughts of Revenge, Angry Afterthoughts, and Understanding of Causes in both samples. Findings established good psychometric properties, evidence of convergent and discriminant validity, and associations in the expected direction with related variables. Males in both samples endorsed Thoughts of Revenge significantly higher. Spanish participants scored higher on Angry Memories and Understanding of Causes. Conclusions The ARS is a valid measure of anger rumination in Australian and Spanish populations. Further, gender and cultural variations may influence the tendency to engage in anger rumination.
Biochemical significance of autoantibody titers against oxidized low-density lipoprotein in patients with coronary heart disease

-Oxidative modification of LDLwhich plays a key role in the development of atherosclerosis-induces immunogenic epitopes in LDL molecule, and the presence of anti-OxLDL (aOxLDL) has been demonstrated in human sera . Although its biological significance in atherogenesis is unclear and not well established.The purposes of this study were to assess whether aOxLDL is related to other inflammatory markers of possible interest in atherosclerotic development, such as C-reactive protein (CRP). Moreover, to search for any correlation with lipid profile , or creatine kinase (CK) and isoenzyme (CK-MB) . Fifteen patients (10 men and 5 women; mean age 41-64 years) with unstable angina (UA). Another fifteen patients (11 men and 4 women; mean age 40-65 years) with acute myocardial infarction (AMI). Ten healthy volunteers with matched age and sex were included in this study. Laboratory investigations included: Full lipid profile, C-reactive protein (CRP) ,cereatine kinase (CK) and iso enzyme (CK-MB) and also troponineI as well as serum titers of auto antibodies against Oxidized LDL (aOxLDL) were assessed by ELISA. Elevated aOxLDL (antibody titers) were observed in AMI and UA than controls (418.40 ± 202.05, 287.13 ± 101.75, 182.90 ± 51.02 mU/ml respectively). The higher levels of aOxLDL and CRP were statistically significant in AMI than UA than controls (F = 10.606, P = 0.000 and F = 27.519, P = 0.000, respectively). On the other hand There was no significant correlation observed between these values ( r = -.160 , p = 0.568 ) . There is no correlation between aOxLDL and lipid profile ,total CK and CK-MB. Receiver operating (ROC) curve between UA and AMI revealed a cut off value = 307.5 mU/ml. There was an 8 fold increased risk of developing AMI (95 % confidence interval, 1.5-42.0, p = 0.025). The elevated levels of aOxLDL may be useful for identifying Patients of higher risk for cardiac events. It may also be a marker of plaque instability to be considered in the therapeutic strategy in acute coronary syndrome.
Performance Assessment Of Embolic ProtectionFilters For Carotid Artery Stenting

Stroke is the third leading cause of death in the United States, accounting for 1.5 deaths reported per 1000 people. Carotid artery stenting (CAS) with cerebral protection is slowly becoming the gold standard for treatment of carotid artery occlusive disease in high risk patients. CAS is based on the selective cannulation of the common carotid artery by means of an introducer sheath or guiding catheter and the deployment of a wire mesh (stent) to treat the occluded artery segment. The goal for CAS is the prevention of stroke and its efficacy depends greatly on the periprocedural complications. The major concern with CAS is its potential to produce emboli that may translate into a severe neurological disorder. In this regard, several cerebral protection devices (CPDs) have been developed recently as an adjunct to CAS, with the primary function of capturing the plaque particles released from the site of vessel injury to prevent neurological events. A category of CPD that has received recent attention due to its ability to allow continued distal perfusion is the embolic protection filter. We tested in vitro one FDA approved (RX Accunet Embolic Protection System, Guidant Corporation, Indianapolis, IN) and two investigational (FilterWire EZ, Boston Scientific, Natick, MA and Angioguard XP, Cordis Corp., Coral Gables, FL) devices of this kind. The objective of this study was to assess the effectiveness of emboli capture of the devices, investigate potential intangible failure modes and complications, and set a baseline of desirable design parameters for future generations of embolic protection filters. None of the devices tested completely prevented embolization into the artery model. Overall, the RX Accunet device had the best filtration performance, failing to capture 0.16% of plaque particles when deployed in an artery model of 5.5 mm in diameter. Several complications related to device retrieval were detected in all devices on any given set of testing scenarios. Crossing profile, opening/closing mechanics and pore size were among the key design variables required for improved device designs.
A novel high-performance utility-interactive photovoltaic inverter system

This paper presents a novel photovoltaic inverter that cannot only synchronize a sinusoidal AC output current with a utility line voltage, but also control the power generation of each photovoltaic module in an array. The proposed inverter system is composed of a half-bridge inverter at the utility interface and a novel generation control circuit which compensates for reductions in the output power of the system that are attributable to variations in the generation conditions of respective photovoltaic modules. The generation control circuit allows each photovoltaic module to operate independently at peak capacity, simply by detecting the output power of the system. Furthermore, the generation control circuit attenuates low-frequency ripple voltage, which is caused by the half-bridge inverter, across the photovoltaic modules. Consequently, the output power of the system is increased due to the increase in average power generated by the photovoltaic modules. The effectiveness of the proposed inverter system is confirmed experimentally and by means of simulation.
A Randomized Clinical Trial: The Efficacy of Hypochlorous Acid on Septic Traumatic Wound.

Background: Hypochlorous acid is a highly microbiocidal active agent against a broad spectrum of microorganisms. It achieved a marked reduction in the bacterial burden in a septic wound. This study aimed to evaluate the efficacy of Hypochlorous acid as a wound care agent in a septic traumatic wound. Materials and Method: Design : The current study used a randomized clinical trial to investigate the effectiveness of Hypochlorous acid as a wound care agent in a septic traumatic wound. Setting : trauma unit at Assiut university hospital was the setting of the study. Subjects: A random selection of 60 patients was done. Then a random distribution of the subjects to study group and control group, (30 subjects each) was done. Methods : The 30 subjects of the study group received Hypochlorous Acid for daily washing a septic wound for 3 to 5 minute, while the 30 subjects of the control group received Povidine Iodine and the results were compared. Bacterial count and culture were done before start washing, after one week, and two weeks in the two groups. Results: wound pain, odor, discharge and bacterial count were dramatically reduced by using as a disinfectant agent compared to the use of Povidine Iodine. Conclusion: Hypochlorous Acid appears to be inexpensive, easy to perform, painless and effective as a potent wound care dressing against a wide range of microorganisms. Hypochlorous Acid controls the tissue bacterial bio-burden without inhibiting the wound healing process, rapidly relieves pain and the area well prepared to skin flap or graft. Recommendation: The study recommended the use of Hypochlorous Acid as a potent wound care dressing. Further research is needed on a larger scale to validate the effectiveness of Hypochlorous acid as a wound care agent in a septic traumatic wound.
