QCBA: Postoptimization of Quantitative Attributes in Classifiers based on Association Rules

The need to prediscretize numeric attributes before they can be used in association rule learning is a source of inefficiencies in the resulting classifier. This paper describes several new rule tuning steps aiming to recover information lost in the discretization of numeric (quantitative) attributes, and a new rule pruning strategy, which further reduces the size of the classification models. We demonstrate the effectiveness of the proposed methods on postoptimization of models generated by three state-of-the-art association rule classification algorithms: Classification based on Associations (Liu, 1998), Interpretable Decision Sets (Lakkaraju et al, 2016), and Scalable Bayesian Rule Lists (Yang, 2017). Benchmarks on 22 datasets from the UCI repository show that the postoptimized models are consistently smaller -- typically by about 50% -- and have better classification performance on most datasets.
Benefits of Cardiovascular Rehabilitation of Insufficient Cardiac to the Institute of Cardiology of Abidjan

Objective: Our work aims to propose a simplified approach by the cardiovascular rehabilitation for the cardiac heart failure. Method and Patients: We realized an observational prospective study during 12-month period which included 85 cardiac heart failure patients at Abidjan Cardiology Institute. Results: 85 patients were included in our study; the average age was 45 ± 20 years. The ratio-sex (men/woman) was to 2. Six patients abandoned the study due to financial issues so that we continued the study with 79 patients. According to the stage of cardiac failure by New York Heart Association (NYHA): after the cardiac rehabilitation, the values of P (P = 0.000) confirmed that the rehabilitation improved considerably the potency tolerance. 60 patients (75%) were at the NYHA II, III stages. According to potency test results, rehabilitation improved significantly the patients potency in watt of the (P = 0.000). According to left ventricle ejection fraction: rehabilitation improved patients cardiac output. Variability rate was 50% for the cardiac output between 20% - 30% and 30% - 40%. Conclusion: In addition to drug therapy, cardiovascular rehabilitation is now recognized in the management of heart failure. Improvements of signs and patients’ life quality remain the major benefits of Cardiovascular Rehabilitation and the reduction of hospitalizations and mortality.
Poster-Paper-Submission (2 pages) for the ICCM meeting 2003 in Bamberg (Germany) Abstract Title: Attentional effects in a model of two reciprocally connected visual areas

Title: Attentional effects in a model of two reciprocally connected visual areas Authors: Andreas Knoblauch and Günther Palm Abstract: Even when creating a biologically realistic model for an apparently very simple cognitive task like seeking a certain object in the visual field, one is confronted with severe problems concerning binding of distributed representations. In this work we present simulation results from a model of two reciprocally coupled visual cortical areas. One area is a peripheral visual area where local object features are represented, the other is a more central visual area where whole objects are recognized. In our model, correct binding is achieved by the simultaneous switching of the activation state of corresponding neuron groups. We relate our simulations to neurophysiological findings concerning attention and biased competition, and demonstrate how these findings can be explained very naturally by assuming different kinds of bindings between neuron groups in different areas as produced by our model. While the binding is fluctuating in the absence of attention, it becomes static by the attentional bias. This leads us to several predictions for neurophysiological experiments.

THE COST OF SCHOOLING: DOES IT MATTER?

The objectives of this study are to identify what schooling costs are borne by parents, to assess the extent to which these costs place a financial burden on parents, and to examine the impact of schooling expenditure on student performance. In addition, the study was to explore the differences in the costs of schooling between rural and urban children in Malaysian secondary schools. A sample survey with a cross-sectional design was carried out in 2005 to cover 1, 742 Form Four students from 25 secondary national schools in four states of Peninsular Malaysia. The results from detailed analysis were categorized into four main observations: (1) the breakdown of schooling expenditure; (2) schooling expenditure as percentage of income, (3) parental perception on the burden of schooling, and (4) the impact of schooling expenditure on student performance. The evidence underscores the importance of schooling expenditure and the spreading the availability of schooling facilitates to all. Providing sufficient financial assistance such as subsidies and scholarships for poor students should continue to be very high on policy agenda.
Multipurpose prevention technologies.

Sexually active women can be exposed to the risk of unintended pregnancy and sexually transmitted infections (STIs) including HIV. Condoms both male and female are currently the only methods that provide simultaneous protection against these risks. Condom use either alone or in addition to another reliable contraceptive method has increased substantially over the last 20 years particularly among unmarried women but condom use among married couples or stable partnerships has remained at very low rates. Both male and female condoms in particular need to be made available accessible and promoted for correct and consistent use. An alternative and novel approach focuses on the development of other multi-purpose prevention technologies or MPTs. These new products are being developed to simultaneously address but not be limited to more than one sexual and reproductive health prevention need of women. As such these products reflect the needs of women within a life-course approach since the sexual and reproductive health needs and goals of women change and evolve over time. (excerpt)
Qualitative Analysis Of Challenges Facing Head Teachers In Management Of Special Schools In Ghana: Implications For Teacher Retention

The study attempts to explore the challenges confronting head teachers in the management of special schools in Ghana. The study was conducted using qualitative research design. Nine out of 29 head teachers were sampled for the study. All head teachers stressed that they were confronted with numerous challenges that affect the management of the schools. The main challenge identified by the study participants was that special education teachers in Ghana were not adequately motivated. The study therefore recommended that special incentive packages be instituted for teachers in the schools and that the Ministry of Education should release funds on time to the schools to enable the school management acquires the resources needed for effective teaching and learning in the special schools.
Parallel Operation of Current-Source Inverter for Low-Voltage High-Current Grid-Connected Photovoltaic System

Solar energy is very potential to be developed in a tropical country such as in Indonesia. This energy source is eco-friendly because it can eliminate air pollution such as caused by conventional fossil fuels. This research article presents analysis results of a novel grid-connected photovoltaic system using low-voltage high-current system. The electrical energy produced by the photovoltaic system was sent into the electrical power grid using two or more H-bridge current source inverters operated in parallel. The proposed system is very suitable for large size photovoltaic system because of its some merits. The inverter circuits work generating sinusoidal output currents and controlling the power delivered into the grid. The test results of the new system showed that the system worked properly as interface between photovoltaic system and the electrical grid delivering high ac current with low harmonic distortion.
[Adult mortality in developing countries: a global overview].

"The article analyzes [selected] developing countries with reliable information on adult mortality between ages 15 and 65 years.A brief analysis of each country indicates the following aspects. Females maintained a more sustained and systematic decline of adult mortality than males. There are some countries that in spite of reasonable development, as Mexico, still have a great excess of male mortality in relation to other countries. Finally, some countries experienced a stagnation of the male mortality decline, while females continued benefiting from a decline of mortality. " (SUMMARY IN ENG)
Aquatic Microbial Food Webs: Structure and Function

Investigations in marine microbial ecology have tended to be restricted in scope to subdiciplines, such as phytoplankton ecology, bacteriology, or protozoology, a fact most probably a result more of historical traditions in educational systems, rather than from the potential for any of one of these subdiciplines alone to fully explain the mechanisms regulating the role of any of one microbial group in the ecosystem. We discuss how the control of bacterial production in the pelagic photic zone can be understood as a combination of competitive, commensal, and predatory mechanisms, involving phytoplankton, bacteria, and protozoa in a tightly coupled network. With particular focus on the Mediterranean, we discuss how such an approach can explain features observed in phosphate deficient systems. The prolonged existence of a population in an ecosystem requires that, over time, growth balance losses. This may seem self-evident, yet investigations of the dynamics of populations often tend to focus on only one aspect of these processes, such as growth conditions determined by competition for food or losses due to predation or viral lysis. The importance of considering both processes simultaneously can be illustrated by a simple four population model (Fig. 1) with heterotrophic flagellates preying on bacteria, ciliates preying on autoand heterotrophic flagellates, and bacteria competing with autotrophic flagellates for mineral nutrient [8]. In the Mediterranean, investigations both in the northwest [10, 11] and eastern basin [12] indicate that growth rates of both phytoplankton and heterotrophic bacteria can be simultaneously P-limited. From theoretical arguments, bacteria, with their high surface:volume ratio, are expected to be the superior competitors for free phosphate at permanently low phosphate concentrations. Considering competition only, this leads to the following variation of Hutchinson’s paradox : Why do bacteria not outcompete phytoplankton until primary production decreases to a level where bacteria become C-
Questionnaire to assess health-related quality of life in sickle cell adults

Los estudios sobre calidad de vida relacionada con salud (CVRS) en drepanocitosis son escasos y no existen instrumentos específicos en español para su evaluación. En este artículo se describe el desarrollo y validación del breve cuestionario específico sobre calidad de vida en drepanocitosis (CEB-S) que ha sido creado para evaluar la calidad de vida de pacientes con drepanocitosis a partir de la valoración que estos hacen de cuánto la enfermedad afecta la calidad de sus vidas. El desarrollo de este instrumento incluyó las fases: creación de preguntas, estudio piloto y estudio de campo. La versión preliminar estuvo formada por 33 preguntas cerradas tipo Likert que se aplicó a 20 hombres y 20 mujeres con drepanocitosis. De su análisis se obtuvo una segunda versión de 30 preguntas en 4 escalas que se aplicó a 104 pacientes. El análisis psicométrico incluyó: evaluación de confiabilidad, validez, sensibilidad, especificidad y eficiencia. Se determinó la confiabilidad del cuestionario en términos de consistencia interna por el índice de Crombach (área física 0,82; área social 0,82; área emocional 0,76; dolor 0,85 y total 0,92). En 69 enfermos se obtuvo un fuerte criterio de validez convergente con el cuestionario de salud SF-36. Se demostró la validez discriminante del CEB-S, al comparar los resultados obtenidos por los pacientes con cualquier tipo de síntoma relacionado con la enfermedad, con los alcanzados por los asintomáticos y también con la estratificación de los enfermos según la gravedad de la anemia en el momento de su aplicación. Esta versión fue considerada como la definitiva.
A THESIS FOR THE DEGREE OF MASTER OF SCIENCE Identification of Point Mutation on Acetylcolinesterase1 and Candidate Genes Related to Carbofuran Resistance in Laodelphax striatellus (Hemiptera: Delphacidae)

Laodelphax striatellus is an important pest of rice due to not only sucking rice seedlings, but also transmitting serious plant viruses. Among various kinds of insecticide groups (carbamates, organophosphorus, neonicotinoids, etc.), carbofuran, a systemic carbamate insecticide, has been most extensively used to control rice pests including L. striatellus, resulting in widespread carbamate resistance in Korea and other Northeast Asia countries. To establish highthroughput screening systems for insecticide resistance management, molecular diagnostic markers are required. Here, we have used the carbofuran selected strains (SEL0 to SEL9) to find a single amino acid point mutation associated with carbamate resistance in the type-1 acetylcholinesterase (Lsace1). When the
III . TYPES OF POWER SYSTEM INSTABILITIES DURING SYSTEM DISTURBANCES

This paper discusses why voltage as well as frequency load shedding may be necessary to prevent major system blackouts. Investigations of recent blackouts [1,3,7] indicate that the root cause of almost all of these major power system disturbances is voltage collapse rather than the underfrequency conditions prevalent in the blackouts of the 1960 and ‘70s. This paper explores the nature of recent power system blackouts (2003 east coast, 1996 California and others) and explains why voltage collapse is the leading edge indicator of impending power system problems. It also discusses the design and security issues that need to be addressed in the design of an undervoltage load shedding (UVLS) scheme and why relying on underfrequency load shedding (UFLS) may be “too little, too late. ” The paper addresses the current level of UVLS on utility systems as well as current NERC (North American Electric Reliability Council) pronouncements on the subject.
Evaluation of Environmental Impacts of Organic Farming by LCA method - Greenhouse Gases from Corn Production

Organic farming is perceived as a system with a number of positive impacts on all components of the environment. For more precise assessment of differences in environmental impacts of conventional and organic farming, we need to be able to measure and quantify such impacts. For this the LCA (Life Cycle Assessment) method may be used as a tool. Among other, the LCA method is also an invaluable tool for assessing GHG emissions related to agricultural production. In this paper, the use of LCA for evaluation of GHG emissions from Zea Mays L. growing is presented. The emission load was calculated by the simplified method LCA, impact category: climate change. The calculation was performed by SIMA Pro software with integrated ReCiPe Midpoint (H) method. The functional unit of the system was represented by 1 kg of corn grain. The model life cycle includes the farm phase (field emissions, seed and planting, fertilizers, plant protection products, agrotechnical operations), calculation of field emissions is also included. The results based e.g. on the yields in Cameroon show clear differences between conventional and organic growing of corn. The GHG emissions expressed in CO2e are after calculation on production unit 38.57 % lower in organic farming, compared to conventional farming.
Interictal Single-Voxel Proton Magnetic Resonance Spectroscopy of the Temporal Lobe in Dogs With Idiopathic Epilepsy

Proton magnetic resonance spectroscopy (H1-MRS) could provide insight into the metabolic pathophysiology of the temporal lobe of canine brain after seizure. Currently, there is no evidence-based data available on MRS of temporal lobe in dogs with idiopathic epilepsy (IE). The aim of this prospective, cross-sectional study was to evaluate the interictal metabolic activity of the temporal lobe in IE dogs compared to a control group with the use of H1-MRS. Ten healthy dogs and 27 client-owned dogs with IE underwent 1.5-Tesla magnetic resonance imaging (MRI) and single-voxel H1-MRS. The MRS studies were acquired as spin echoes with a repetition time (TR) of 2,000 ms and an echo time (TE) of 144 ms. A cubic voxel (10 ×10 ×10 mm) was positioned bilaterally into the region of the left and right temporal lobe, including a middle part of the hippocampus and the amygdala. The N-acetylaspartate (NAA)-to-creatine (NAA/Cr), NAA-to-choline (NAA/Cho), choline-to-creatine (Cho/Cr), and choline-to-NAA (Cho/NAA) ratios were determined in both hemispheres and compared to controls. No significant differences in all metabolite ratios between epileptic dogs and the control group could be found. A time-dependent decrease in the NAA/Cho ratio as well as an increase in the Cho/NAA ratio was found with proximity in time to the last seizure. We found no correlation between metabolite ratios and age or sex in this animal group. Time span from the last seizure to the acquisition of MRS significantly correlated with NAA/Cho and Cho/NAA ratio. We conclude that without a time relation, metabolite ratios in dogs with IE do not differ from those of the control group.
SurePoint: Exploiting Ultra Wideband Flooding and Diversity to Provide Robust, Scalable, High-Fidelity Indoor Localization: Demo Abstract

We present SurePoint, a system for drop-in, high-fidelity indoor localization. SurePoint builds on recently available commercial ultra-wideband radio hardware. While ultra-wideband radios provide a pairwise range estimate natively, we show that with the addition of frequency and spatial diversity, we can achieve a 53% decrease in median range error. Because this extra diversity requires many additional packets for each range estimate, we leverage an efficient broadcast ranging protocol for localization that ameliorates this overhead. In stationary and fast-moving environments SurePoint achieves up to 0.08 m median error and 0.53 m 99th percentile error. As ranging requires the tag to have exclusive access to the channel, we employ a protocol to coordinate the localization of multiple tags in space. This protocol builds on recent work exploiting the constructive interference phenomenon, however SurePoint is the first to demonstrate constructive interface using the 802.15. 4a ultra-wideband PHY. Finally, as the ranging protocol requires careful management of the ultra-wideband radio and tight timing, we utilize TriPoint, a dedicated "drop-in" ranging module that provides a simple I2C interface. We show that this additional microcontroller demands only marginal energy overhead while facilitating interoperability by freeing the primary microcontroller to handle other tasks. This demo complements the paper "SurePoint: Exploiting Ultra Wideband Flooding and Diversity to Provide Robust, Scalable, High-Fidelity Indoor Localization" to be presented at SenSys'16.

It is known that the treatment is difficult and it requires a full multidisciplinary team of professionals and that the key of prevention is the modification of the sedentary lifestyle and the decrease of energy intake. This guide was elaborated by pediatricians working in nutrition in public and university institutions, family and general physicians and pediatricians with private practice.
BER Improvement of MIMO-OFDM and Adaptive MIMO-OFDM System by using M-PSK

Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing) MIMO-OFDM is one of the promising technologies to improve the spectral efficiency, enhance system capacity and mitigate inter-symbol interference in the fourth generation broadband mobile communication system. In this paper, we aim at the study of a communication system that employs MIMO-OFDM and adaptive modulation technologies. OFDM is one of the best solutions for achieving high data rates in mobile environment, due to its resistance to ISI, which is most common problem found in high speed data communication. A (Multiple-input Multiple-output) MIMO communication System along with the (Orthogonal Frequency Division Multiplexing) OFDM modulation technique can achieve reliable high data rate transmission over broadband wireless channels. In this paper we have achieved, (Bit Error Rate) BER and Channel capacity analysis for MIMO-OFDM and (Adaptive multiuser detection –Orthogonal Frequency Division Multiplexing) AMUD MIMOOFDM by the use of M-ary (Phase Shift Keying) PSK modulation technique.
