Evaluation of left ventricular thickness and function in malnourished child

Malnutrition is an important problem ion the third world. Cardiac complications is an important cause of mortality and morbidity among the children with poor nutrition. A case control study was done on 54 child aged 2-5 years with malnutrition attending Tikrit teaching hospital during the period from 1st of February 2007 to the 1st of February 2008 to evaluate the effect of malnutrition on the cardiothoracic ratio on plain CXR . Similar number of normal children were taken as a control with same age range during the period of the study. The total number of cases was 54 , males 37 (68.5%) and females were 17 cases (31.5%). According to the Welcome classification . most of the study cases were marasmic 22 cases (40.7%0) while the least were marasmic kwashiorkor category 8 cases (14.8%). according to the CTR in regard to the water law classification in regard to the total number of cases , most of the cases have CTR between 20-40% 27 case (50%). All the cases with mild malnutrition have normal CTR 8 cases (100%) , most of the cases with moderate malnutrition have CTR between 20-40% , 22 case (59.5%) while for the sever malnutrition , most of the cases have also CTR between 20-40% , 5 case (55.6%). according to the Welcome classification. Regarding the marasmus cases , 9 case (40.9%) have CTR between 2040% and 8 cases (36.4%) were between 40-50%. Most of the kwashiorkor patients have CTR between 20-40 % , 8 cases (66.7%) which is similar to the marasmus kwashiorkor category 6 cases (75%0. most of the under weight patients have CTR between 40-50% , 7 cases (58.3%). In diasystole . there is significant decrease in the left ventricular wall thickness for septum 38(70.3%) and posterior wall 39(72.2%) as compared o the control cases (0%). In systole, there is significant decrease in the left ventricular thickness for septum 48(88.9%) and posterior wall 47(87%) as compared to the control cases (0%). Most of the malnutrition cases had increased heart rate 38(70.4%) as compared to the control cases 3(5.6%). There is significant decrease in the stroke volume in the malnutrition cases 44(81.5%) as compared to the control cases (0%). There is significant decrease in the cardiac output in the malnutrition cases 44 (81.5%) as compared to the control cases (0%). As well as there is significant decrease in the cardiac contractility in malnutrition cases 53 (98.1%) as compared to the control cases (0%). Regarding the fractional shortening and ejection fraction, there is significant decrease in the fractional shortening in the malnutrition cases 44 (81.5%) as compared to the control cases (0%) as well as there is significant decrease in the ejection fraction in malnutrition cases 44(81.5%) as compared to the control cases (0%). There was no significant difference regarding the left ventricular function or mass in patients with marasmus as compared to those with kwashiorkor or marasmic kwashiorkor. The study concludes that malnourished patients have smaller CTR compared with well nourished ones with significant decrease in the left ventricular thickness and function.
Automated Failure Detection in Computer Vision Systems

Human validation of computer vision systems increase their operating costs and limits their scale. Automated failure detection can mitigate these constraints and is thus of great importance to the computer vision industry. Here, we apply a deep neural network to detect computer vision failures on vehicle detection tasks. The proposed model is a convolution neural network that estimates the output quality of a vehicle detector. We train the network to learn to estimate a pixel-level F1 score between the vehicle detector and human annotated data. The model generalizes well to testing data, providing a mechanism for identifying detection failures.
Informed Trading in Business Groups, Ownership Concentration, and Market Liquidity

Business groups, which are collections of publicly traded companies with significant amount of common ownership, dominate private sector activity in developing countries. This paper studies how information flows within these groups by analyzing the trading behavior of pension fund managers in firms that belong to the same group. The paper shows that while pension fund managers are momentum traders on non-affiliated companies, they trade in anticipation of future abnormal returns in affiliated firms. Ownership concentration and business group ties exacerbate information asymmetries, discouraging investment and depressing stock market participation. Using the merger and acquisition activity among pension fund managers as a natural experiment, the paper provides evidence that increases in stock ownership concentration, via the threat of informed trading, adversely affect liquidity. The results indicate that cross-ownership structures and extensive investor-industry relations might curb the expected benefits from the presence of institutional investors, limiting market development.
Sentiment analysis on medical treatment of depression

Applying ICT approach to contribute to improving human’s life is a good purpose for researchers (Pannel, 1993). Thus, implementing products or services with new techniques can be quite an interesting and meaningful topic. Nature language processing is a mature technique may apply machine learning and this technique has already been applied to many applications to server people such as Siri, Chatbot and Google Now. Sentiment analysis is a subject in nature language processing, however, it has not been applied to many fields in our daily life. Depression is a mental disease which caused a lot of trouble in sociality (Hamilton,1960). It causes a huge damage in people’s daily life in the mental aspect instead of the physical painful. And it is also proved by (Help, 2013) that this kind of mental causing a lot of troubles to patients. Quite many researchers are working to find some better treatments for it. However, similar to any other mental disease, there are many treatments existing for different patients and finding the best treatment for a patient can be a quite difficult job. Thus, in this research, I’m trying to validate the function of the sentiment analysis system by applying the data about depression. In order to achieve this problem, I have defined three research questions which lead to solving this problem. (1) What is the best algorithm for implementing the sentiment analysis system? (2) What is the best existing sentiment lexicon library which can be applied to implement the sentiment analyzing system? (3) How to implement the sentiment analysis system with a selected sentiment lexicon library? During the research process, I review the literature which is related to these questions to find out the answers. After all, I selected an open source the sentiment lexical library named SentiWordNot3.0 which was implemented based on an algorithm has the feature of Kth-Nearest Neighbor algorithm and Support Vector Machine. And it proved that following approach can be actually used in sentiment analysis in the medical domain.
Design of Compact Quad-Channel Diplexer Using Quad-Mode Stub-Loaded Resonators

In this paper, a compact quad-channel diplexer utilizing quad-mode stub-loaded resonators (QMSLRs) is proposed. The proposed quad-channel diplexer is composed of two dual-band bandpass filters (BPFs) based on QMSLRs and source-load coupling lines. Due to the symmetry of the proposed quad-mode resonator, its resonance characteristics are analyzed by using the even-odd-mode method twice. All four modes equivalent circuits of the resonator are quarter wavelength resonators, so the circuit size can be very compact, and the first resonance frequencies is three times of the fundamental ones. Stub-to-stub coupling is introduced to split two identical resonance modes, which is in favor of implementing dual-band BPF by using a single quad-mode resonator. By tuning the corresponding physical dimensions of the stubs, the resonant modes can be individually adjusted. The source-load coupling lines are properly designed to provide appropriate external coupling for the passbands and high isolation level between channels. For demonstration, a quad-channel diplexer (0.9/1.2 GHz at Load 1 and 1.5/1.8 GHz at Load 2) using the quad-mode resonator is designed, fabricated and measured. The simulated and measured results with good agreement are presented.
A New Class of Traceability Schemes for Protecting Digital Content against Illegal Re-distribution

Summary Traceability schemes are used to protect the rights of intellectual-property owners against illegal re-distribution. In order to trace a pirate copy back to a user who has been involved in making and re-distributing the pirate copy, a traceability scheme requires a code which contains a sufficient number of codewords and a traitor-tracing algorithm. Codes with the identifiable parent property (IPP codes) and traceability codes (TA codes) have been extensively studied. IPP codes include all TA codes as special instances. However, TA codes usually implement efficient tracing algorithms, while IPP codes do not always have efficient tracing algorithms. A major theoretical challenge is to derive more codes which have efficient tracing algorithms. The contributions of this paper include a new class of traceability codes, as well as an efficient tracing algorithm for the new traceability codes. The proposed tracing algorithm has the same complexity as the traditional tracing algorithm and can outperform the traditional tracing algorithm.

A New-Keynesian Model of the Yield Curve with Learning Dynamics: A Bayesian Evaluation

We estimate a New-Keynesian macro-finance model of the yield curve incorporating learning by private agents with respect to the long-run expectation of inflation and the equilibrium real interest rate. A preliminary analysis shows that some liquidity premia, expressed as some degree of mispricing relative to no-arbitrage restrictions, and time variation in the prices of risk are important features of the data. These features are, therefore, included in our learning model. The model is estimated on U.S. data using Bayesian techniques. The learning model succeeds in explaining the yield curve movements in terms of macroeconomic shocks. The results also show that the introduction of a learning dynamics is not sufficient to explain the rejection of the extended expectations hypothesis. The learning mechanism, however, reveals some interesting points. We observe an important difference between the estimated inflation target of the central bank and the perceived long-run inflation expectation of private agents, implying the latter were weakly anchored. This is especially the case for the period from mid-1970s to mid-1990s. The learning model also allows a new interpretation of the standard level, slope, and curvature factors based on macroeconomic variables. In line with standard macro-finance models, the slope and curvature factors are mainly driven by exogenous monetary policy shocks. Most of the variation in the level factor, however, is due to shocks to the output-neutral real rate, in contrast to the mentioned literature which attributes most of its variation to long-run inflation expectations.

Resignification of educational e-innovation to enhance opportunities for graduate employability in the context of new university degrees

This paper presents the findings of a training programme based on an Action-Research methodology that has been applied in two subjects of Event Organization, Protocol and Institutional Relations undergraduate and Master’s degrees. Through a teaching methodology called «learning by doing», students are encouraged to understand, internalise and apply the potential of technology in this field of knowledge, by means of building their personal brand as a key for digital literacy and professional empowerment. Thus, firstly this work proposes a review of the use of technology in teaching, with the goal of resignifying the concept of educational e-innovation from a transdisciplinary approach, which promotes progress in education ranging from technological to social innovation (technological-education-cultural-relational). Then, both the specific features and activities designed to build the students’ personal brands during the course as well as the research methodology applied to analyze the results are described. The methodology is based on a longitudinal «ex post-facto» approach through a panel sample survey. Finally, results demonstrate how this training programme has allowed graduates to improve their employability and career development opportunities from then on, encouraging active participation and self-directed learning. Initial conclusions encourage us to apply this experience to larger groups and new university degrees in the higher education context.
The impact of the institutional form on the cost efficiency of nursing homes

In Switzerland, nursing home services are mainly provided by regulated public and private nonprofit organizations. Some of them are created by local governments as foundations. This provides a unique setting to analyze the impact of the institutional form on the performance of nursing homes. We propose a model where the institutional form is represented as a legal constraint which affects managers in the decison-making process. Considering a sample of 44 Swiss Italian nursing homes over a 7-years period (1999-2005), we then disentangle persistent inefficiency due to differences in the institutional form from unobserved heterogeneity. The applied estimation strategy provides more accurate estimates of the impact of the institutional form on nursing homes efficiency, as compared to previous studies. Our results suggest that governmental nursing homes are more costly than private and public foundations. These results are consistent across different model specifications.
Effects of moisture barrier and initial moisture content on the storage life of some horticultural produce in evaporative coolant

Shelf-life of five horticultural produce were studied. These include three leafy vegetables: Telfairia occidentalis, Celosia argentea and Amaranthus cruentus and two fruit vegetables: Lycopersicum esculentum and Abelmuschus esculentus. The layout plan of the experiment was a 3x2 factorial in a completely randomized design and each treatment replicated three times. The two factors examined were moisture barrier at three levels namely: thick lining, thin lining and non-lining. The other factor included initial moisture content of the produce, namely, turgid and partially wilted. Partial wilting of the produce was achieved by exposing freshly harvested materials at ambient temperature to dry for 45 min. During this period, about 20% of the moisture content was lost. Eighteen (18) vegetable baskets which work on the principle of evaporative cooling system were used. Each type of produce was stored at a time inside the vegetable basket. Some quantity of each produce were kept on the laboratory benches to serve as controls. Data recorded includes length of storage of produce, severity of disease infection, visual quality, disease incidence, ambient temperature and relative humidity of the storage baskets. The result indicates that there was a significantly higher relative humidity (P< 0.05) in the lined baskets than in the non-lined baskets. Consequently, the shelf-life of produce in lined basket was prolonged. Turgid produce had better quality retention and stored much longer than partially wilted produce. Generally, the evaporative coolant baskets provided an average temperature of 3°C lower than the ambient condition. The shelf-life of leaf vegetables T. occidentalis, C. argentea and A. cruentus was extended appreciably for 78 days compared to the controls.
Tall trees survival in relation tobottom-up and top-down driversin Hluhluwe-iMfolozi Park, SouthAfrica

Tall trees are in decline throughout many national parks in South Africa. Many studies have found that trees within a certain size are preferred by elephants which damage trees by either bark stripping, breaking tree branches and/or stems or by knocking over trees (toppling). The decline of trees in relation to growing elephant populations is of growing concern, as tall trees are a key stone feature in the savanna ecosystem. One of the parks where elephant populations are increasing is in Hluwhluwe-iMfolozi Park, KwaZulu-Natal. To investigate whether trees within the park are in decline, we set out to revisit previously tagged trees from 2007 to reassess their condition. When revisiting trees a total of 260 trees were found, resulting in a 92.5% success rate in relocation of individual trees. The analyses showed that elephant impact was not descriptive of tree mortality within the park. Two tree species however, Combretum molle and Spirostachys africana, had a lower mortality risk. The risk of elephant impact was mediated by several abiotic variables, such as slope, aspect and elevation. The results of this study further accentuates the need to research the interaction between various factors to understand the causative agents of tall tree mortality.
Biomaterial surfaces differentially adhesive to microbes and mammalian cells

Infecties zijn de belangrijkste oorzaak voor het falen van een implantaat of apparaat gemaakt van een biomateriaal. Het doel van dit proefschrift was het onderzoeken van het mogelijk gunstige effect van ruimtelijk gemodificeerde, anti-hechting polyethyleen glycol (PEG)-microgel patronen op de hechting van micro-organismen, de hechting en spreiding van weefselcellen en, uiteindelijk, de uitkomst van ‘the race for the surface’, om op die manier de kans op een biomateriaal-geassocieerde infectie te verlagen. Om multifunctionele oppervlakken te ontwikkelen hebben we elektronenbundel lithografie gebruikt om nauwgezette PEG-microgel patronen te creeren om het gedrag van meerdere biologische componenten met het interface te beheersen. Vervolgens hebben we een oppervlak gecreeerd met anti-hechting microgel patronen op een oppervlak welke normaliter de hechting van cellen toelaat, waarmee we succesvol waren in het aantonen van differentiele weefselcel- en microbiele-oppervlakte interacties. Dit mechanisme hebben we vervolgens gebruikt onder meer ingrijpende omstandigheden, waarbij de gemoduleerde oppervlakken eerst werden blootgesteld aan fibronectine (Fn) en vervolgens werden onderzocht met een aan Fn hechtende S. aureus stam. Hiermee hebben we aangetoond dat PEG microgel patronen biofilm formatie remmen terwijl weefselcellen goed in staat waren te hechten. De eerste co-cultuur experimenten slaagden er niet in de meerwaarde van de patroonoppervlakken in ‘the race for the surface’ te laten zien, waarschijnlijk veroorzaakt door crosstalk van bacteriele toxines tussen de oppervlakken met patronen en de delen van het glas zonder coating die de patronen omringden. Wij stellen dat co-cultuur experimenten volledig gecoate samples vereisen, waarvoor een fabricage methode ontwikkeld moet worden die het mogelijk maakt om op grote schaal dit soort samples te produceren.

The Term “Business Model” in Financial Reporting: Does It Need a Proper Definition?

In the last five years, the vocabulary of financial reporting has been enriched by a new specific term: “business model”. However, as the expression is rather equivocal, it is not still possible to find an unanimously shared meaning of the term in the literature. Because of the relatively recent application of the term “business model” in financial reporting, the investigation of its proper meaning is still an uninflated topic of research. Specific purpose of this paper is trying to contribute in finding a proper definition of this term when used in financial reporting (if any). In this sense, after having reviewed the main literature on “business model” definition we have analyzed the parts of the comment letters on the IASB’s Discussion Paper 2013/1—titled “Review of the Conceptual Framework for Financial Reporting”—which deal with “business model” definition. In particular, the questions whose answers have been specifically investigated are the following: 1) Should the IASB define “business model”? Why or why not? 2) If you think that “business model” should be defined, how would you define it? However, considering the contrasting definitions found both in the literature and in the comment letters, it is not still possible to get a widely accepted meaning of the term “business model” in financial reporting. For these reasons, at this stage of research, the authors completely agree with the thought of Singleton-Green that asserts, “Defining or agreeing a definition of the term “business model” will not advance our understanding of the financial reporting issues”.
