Iterative Wyner-Ziv decoding and successive side-information refinement in feedback channel-free hash-based distributed video coding

This work presents a novel rate control scheme that suppresses the need for a feedback channel in hash-based distributed video coding (DVC) architectures. Our state-of-the-art DVC schemes generate side-information (SI) at the decoder by means of hash-based overlapped block motion estimation followed by probabilistic motion compensation, where key frames or previously decoded non-key frames, called Wyner-Ziv frames, are used as references. These DVC systems employ powerful low-density parity-check accumulate codes to code the Wyner-Ziv frames in the transform domain. Our previous DVC architectures use a classical decoder-driven rate control scheme with a feedback channel. Specifically, chunks of accumulated syndrome bits are sent from the encoder to the decoder upon request from the latter until successful decoding is achieved. In order to suppress the feedback channel, the encoder of the DVC system, proposed in this work, approximates the SI available to the decoder using a novel low complexity SI generation technique. Subsequently, the conditional probabilities of the original Wyner-Ziv frames, given the approximation of the SI at the encoder, are used to generate an estimate of the required rate for channel decoding. Hence the presence of a feedback channel is evaded. Additionally, the proposed feedback channel-free DVC system is equipped with advanced reconstruction techniques to reduce the impact of failed channel decoding. In this context, our DVC architecture features iterative refinement of the SI at the decoder. The latter allows for reattempting to decode Wyner-Ziv data for which the channel decoding failed in previous decoding steps when only a lower quality version of the SI was available. Experimental results show competitive compression performance of our novel feedback channel-free hash-based DVC system with respect to the feedback channel-based benchmark in DVC.
Quantification of Wave Model Uncertainties Used for Probabilistic Reliability Assessments of Wave Energy Converters

Wave models used for site assessments are subjected to model uncertainties, which need to be quantified when using wave model results for probabilistic reliability assessments. This paper focuses on determination of wave model uncertainties. Four different wave models are considered, and validation data are collected from published scientific research. The bias and the root-mean-square error, as well as the scatter index, are considered for the significant wave height as well as the mean zero-crossing wave period. Based on an illustrative generic example, this paper presents how the quantified uncertainties can be implemented in probabilistic reliability assessments.
Prevalence of anemia and its etiology: a study in a semi urban area

Introduction: Anemia is recognized as a public health problem throughout the world affecting both developed and developing countries and is associated with nutritional deficiencies especially due to iron deficiency, which is the main factor for microcytic anemia, while folate or Vitamin B12 deficiencies are known to be responsible for macrocytic anemia. This study was conducted to estimate the prevalence of anemia in our area and its association with the lack nutrients. Materials and Methods: General demographic details such as age, gender, weight, economic status of the parents, etc were taken for 392 children between the ages of 6 months to 5 years. Blood samples were taken for all the patients for hemoglobin levels and estimation of iron, folic acid and Vitamin B12. Results: 179 (45.7%) patients were found to be anemic. Of them, 91 (50.8%) were with mild anemia, 76 (44.1%) were with moderate anemia. Severe anemia accounted for only 9 (5.0%) of the cases. Out of patients, the most prevalent age group with anemia was found to be 12-<24 months, followed by 6-<12 months. Of the micronutrients testes, iron deficiency either pure or mixed with other nutrients was the most predominant with folic acid deficiency being the lowest. Conclusion: Proper food, rich in nutrients, iron supplements are some of the essential requirements with regular check ups for the children below 5 years. Education regarding the importance of nutrition and harmful effects of iron deficiency on the child must be given.
ORIGINAL PAPER Erythropoietin therapy in chronic renal failure patients prior to hemodialysis

The human recombinant erythropoietin (hrEpo) is crucial in anemia treatment options in chronic renal failure patients undergoing regular hemodialysis therapy. However, the clinical characteristics of erythropoietin treatment prior to hemodialysis have not been thoroughly studied. This study was aimed to analyze in retrospective manner the results of hrEpo therapy in chronic renal failure prior to hemodialysis. The study included 42 patients (26 males and 16 females, 42.4±3.7 yrs old) with mean serum creatinine 305±32 µmol/l, whose anemia and iron homeostasis parameters were carefully assessed. HrEpo improved both the general state of the patients and the life quality, it decreased cardiovascular complications and the mortality of patients prior to hemodialysis therapy. Iron supplementation during erythropoietin therapy was required, in the majority of patients oral iron was sufficient. The application of human recombinant erythropoietin prior to hemodialysis is a safe option, it does not accelerate the progression of chronic renal failure, only in a small number of patients moderate increase of blood pressure was noted that could have been effectively managed with the modification of doses of hypotensive pharmacotherapy.

Artificial Intelligence :, A Prospective Or Real Option For Education

The education sector is grappling with a plethora of challenges that have compelled scholars and practitioners to begin looking for a solution. Artificial intelligence (AI) is among the proposed solutions that is having significant attention lately. However, its adoption in the education sector remains low because of challenges, such as lack of proper trials, testing, and recommendation for its applicability in the sector. This article seeks to explore the role and potentiality of AI in improving education. A systematic review design is used for this purpose. The methodology corresponds with the rapid survey protocol of Khangura )2012( which provides an eight-step systematic research literature review of several studies that have been carried out on the embedment of artificial intelligence in education. This article concludes that AI could play an instrumental role by developing a digital curriculum, automating basic educational activities, and adopting Chat-bot related Apps. Implications for future research are provided to form the basis for further and future studies. Key terms: artificial intelligence, education, Arab World, apps, curriculum. ةش�لاخ ثحبلا ءدبل ينيّمداكألاو ينثحابلا تعفد يتلا تايدحتلا نم اًيربك اًددع ميلعتلا عاطق هجاوي ةنوآلا في يربك مامتهاب ىظتح يتلا ةحترقلما لوللحا ينب نم وه يّعانطص�لا ءاكذلا . لّح نع لىإا راقتفلا لثم ،تايّدحتلا ببص�ب اًص�فخنم ميلعتلا عاطق في هدامتعا لازي ل ،كلذ عمو . ةيرخألا فاص�كتص�ل ةلاقلما هذه ىعص�ت . عاطقلا اذه في هقيبطتب ةيص�وتّلاو ،رابتخلاو ،ةميلص�لا براجتلا -121DOI: 10.33986/0522-000-011-018
Analytical Performance of Aufomated Methods for the Determination of the Tumor Markers CA 15-3 and CA 19-9: A Comparison Between Immunoluminometric and Immunomagnetic Assays.

Although identical monoclonal antibodies from the same source are used, the analytical performance of commercial assays for the measurement of the tumour markers CA 15-3 and CA 19-9 may be quite different. In the present study immunoluminometric (ILMA, LIA-mat, Byk-Sangtec) and immunomagnetic (MSA, Technicon Immuno l ®, Bayer Diagnostics) assays for CA 15-3 and CA 19-9 are compared. Comparisons with the microparticle enzyme immunoassay (MEIA, Abbott) were also performed. MSA exhibited an excellent interassay-precision for the two analytes with coefficients of variation (CVs) between 2 and 4%, while the CVs with the ILMA ranged between 5 and 8%. In the CA 19-9 determination the regression analysis yielded MSA = 0.927 * ILMA 2.131 kU/1; r = 0.975; Sy.x = 21.3 kU/1; n = 72). Comparison studies with the MEIA showed regression factors for MSA and ILMA in the order of 1.13 and 1.27, respectively. With the ILMA, samples exhibiting CA 19-9 concentrations above the dilution limit yielded results that deviated up to 2.6-fold from the comparison methods. A falsely low result was observed with the ILMA in a liver-transplant patient. The investigation of the CA 15-3 methods using sera from patients with mammary carcinoma relapse (n = 156) yielded different regression lines between MSA and ILMA results depending on the concentration range. CA 15-3 values obtained with the MSA agreed well with the MEIA results. With the ILMA, dilution linearity was not found to be satisfying within and above the measuring range.
Automated discovery of self-replicating structures in cellular space automata models

This thesis demonstrates for the first time that it is possible to automatically discover self-replicating structures in cellular space automata models rather than, as has been done in the past, to design them manually. Self-replication is defined as the process an entity undergoes in constructing a copy of itself. Von Neumann was the first to investigate artificial self-replicating structures and did so in the context of cellular automata, a cellular space model consisting of numerous finite-state machines embedded in a regular tessellation. Interest in artificial self-replicating systems has increased in recent years due to potential applications in molecular-scale manufacturing, programming parallel computing systems, and digital hardware design, and also as part of the field of artificial life. In this dissertation, genetic algorithms are used with a cellular automata framework for the first time to automatically discover self-replicating structures. The discovered self-replicating structures compare favorably in terms of simplicity with those generated manually in the past but differ in unexpected ways. This dissertation presents representative samples of the self-replicating structures and analyses them both quantitatively and qualitatively. In order to effectively search the underlying rule space of such automata models, a fitness function consisting of three independent criteria is designed and successfully applied. Also, a new cellular space automata model called effector automata is introduced. It is shown to be more computationally feasible and to promote the discovery of more self-replicating structures as compared to the cellular automata models used in previous studies. In addition, a new paradigm for cellular space models with weak rotational symmetry called component-sensitive input is introduced and shown to facilitate discovery of self-replicating structures. The results presented suggest that genetic algorithms can be powerful tools for exploring the space of possible self-replicating structures. Furthermore, this research sheds light on the nature of creating self-replicating structures and opens the door to further studies that could eventually lead to the discovery of new self-replicating molecular structures.

Towards more efficient meta-heuristic algorithms for combinatorial test generation

Combinatorial interaction testing (CIT) is a popular approach to detecting faults in highly configurable software systems. The core task of CIT is to generate a small test suite called a t-way covering array (CA), where t is the covering strength. Many meta-heuristic algorithms have been proposed to solve the constrained covering array generating (CCAG) problem. A major drawback of existing algorithms is that they usually need considerable time to obtain a good-quality solution, which hinders the wider applications of such algorithms. We observe that the high time consumption of existing meta-heuristic algorithms for CCAG is mainly due to the procedure of score computation. In this work, we propose a much more efficient method for score computation. The score computation method is applied to a state-of-the-art algorithm TCA, showing significant improvements. The new score computation method opens a way to utilize algorithmic ideas relying on scores which were not affordable previously. We integrate a gradient descent search step to further improve the algorithm, leading to a new algorithm called FastCA. Experiments on a broad range of real-world benchmarks and synthetic benchmarks show that, FastCA significantly outperforms state-of-the-art algorithms for CCAG algorithms, in terms of both the size of obtained covering array and the run time.
Ecoinvolúcrate: alternativa para la sostenibilidad en la arquitectura

Sustainability and architecture make close their relationship from the conceptual idea, and although sustainability goes beyond, it is present from the moment in which we study the basics of architecture, stage in which it is defined how satisfied the needs of the user and implement them based on a previous study, and based on the use and function that will have every space. This is why, when the materials are determined to use in construction, is established the degree of intervention in the environment.Keywords: Sustainability, architecture, energy efficiency, education.
Dengue outbreak 2013: Clinical profile of patients presenting at DHQ Burner and THQ Shangla, Khyber Pakhtunkhwa, Pakistan

We evaluated the clinical features, disease severity, laboratory findings and outcome of serologically confirmed cases of Dengue fever in Patients during the recent outbreak in two districts (Buner & Shangla) in 2013, Khyber Pkhtunkhwa, Pakistan. We encountered 320 cases of Dengue fever during 5 months period (July to November, 2013). The dengue infection rate in females (180: 56%.2) was higher as compared to males (140: 43.8%). The dengue infections were more frequently seen in the post-monsoon season than in the monsoon period. The death ratio in the overall weighted prevalence was 0%. All the patients suffered from fever but no specific pattern could be identified, degree was variable ranging from low to high grade. Abdominal pain was the next most common symptom followed by vomiting and diarrhea. Only (45%) patients complained of body aches and pains, (30%) patients had hemorrhagic manifestations in the form of gum bleed, and (05%) patients had melena while (15%) patient’s complained of skin rashes. The most common clinical sign was the Enlarged liver that was present in (75%) patients. There is critical need for molecular and entomological surveillance of dengue among the dengue epidemics-prone areas to eliminate the disease.
Avian influenza overview February – May 2018

Between 16 February and 15 May 2018, three highly pathogenic avian influenza (HPAI) A(H5N6) and 11 HPAI A(H5N8) outbreaks in poultry holdings, one HPAI A(H5N6) and one HPAI A(H5N8) outbreak in captive birds, and 55 HPAI A(H5N6) wild bird events were reported in Europe. There is no evidence to date that HPAI A(H5N6) viruses circulating in Europe are associated with clades infecting humans. Fewer HPAI wild bird cases have been detected than during the same period of previous year. Most of mortality events among wild birds involved single birds and species listed in the revised list of target species for passive surveillance. Raptor species constitute 74% of the HPAI‐infected wild birds found dead. Those raptor species probably became infected by hunting or scavenging HPAI virus‐positive birds, and so raptor cases may predominate later in the course of an HPAI epidemic. Despite the important HPAI virus incursion via wild birds there have been few associated HPAI A(H5N6) outbreaks in poultry. Fifteen low pathogenic avian influenza (LPAI) outbreaks were reported in three Member States. The risk of zoonotic transmission to the general public in Europe is considered to be very low. The situation in Africa and the Middle East should be closely monitored with regards to HPAI A(H5N1) and A(H5N8). Uncontrolled spread of the virus and subsequent further genetic evolution in regions geographically connected to Europe may increase uncertainty and the risk for further dissemination of virus. Long‐distance migrating wild birds from southern Africa, e.g. the common tern (Sterna hirundo), may be included in targeted active surveillance schemes at a few priority locations in Europe in order to detect HPAI A(H5)‐infected migrating birds early. However, the risk of HPAI introduction from non‐EU countries via migratory wild birds to Europe is still considered to be much lower for wild birds crossing the southern borders than for those crossing the north‐eastern borders.
CC++: A Declarative Concurrent Object Oriented Programming Notation

CC++ is Compositional C++, a parallel object-oriented notation that consists of C++ with six extensions. The goals of the CC++ project are to provide a theory, notation and tools for developing reliable scalable concurrent program libraries, and to provide a framework for unifying: 1.distributed reactive systems, batch-oriented numeric and symbolic applications, and user-interface systems, 2.declarative programs and object-oriented imperative programs, and 3.deterministic and nondeterministic programs. This paper is a brief description of the motivation for CC++, the extensions to C++, a few examples of CC++ programs with reasoning about their correctness, and an evaluation of CC++ in the context of other research on concurrent computation. A short description of C++ is provided.
Síndrome metabólica: complacência arterial e a velocidade de onda de pulso

The metabolic syndrome (MS) is characterized as a complex disorder represented by a set of cardiovascular risk factors, its frequency estimated between 20% to 25% of the adult population worldwide. The various components of MS are responsible for structural and functional alterations of large arteries, among which a decrease in arterial compliance stands out as an important cardiovascular risk marker. Measurement of Pulse Wave Velocity (PWV) figures as a relevant method in the evaluation of arterial stiffness. This review discusses the main mechanisms by which components of MS act causing these vascular changes, the relevance of these changes and the reflex of treatment influence in these cases. A literature review was conducted by consulting electronic databases Medline, Pubmed and Lilacs between years 2008 and 2009. Metabolic syndrome, pulse wave velocity and arterial stiffness, and their Portuguese equivalents, were the search words used, selecting studies dating from 1962 to 2009. The reviewed studies showed that the components of MS act through different mechanisms to promote the increase of PWV. The main change related to these vascular components was decreased compliance of large arteries. Assessment of arterial compliance by measuring PWV allows tracking the results obtained through therapeutic interventions and early identification of these vascular changes. It thus becomes possible to adopt an early treatment measure, which allows to slow down the progression of these vascular changes significantly and therefore reduce cardiovascular mortality in these patients.
Application of Sparse Dictionary Adaptive Compression Algorithm in Transient Signals

An adaptive compression algorithm based on sparse dictionary is proposed to solve the pressure on the transmission system caused by long-time high sampling rate sampling of transient signals. Due to the obvious difference between transient and non-transient information features of transient signals. According to the sparse dictionary construction characteristic that the more matching atoms and signal features are, the better sparse performance is, the transient signal feature information is extracted and compressed separately. After data compression, the principle of compressed sensing is applied to restore the transient signal, so as to reduce the amount of data transmitted in the transmission system. In summary, the adaptive sparse dictionary compression algorithm effectively compresses the transient signal data, and the compressed data can accurately recover the transient signal.
