Abstract In this paper, the mathematical model describing the third-grade nonNewtonian blood flow suspended with nanoparticles through porous arteries is exactly solved. The present physical model was solved in the research literature via the optimal homotopy analysis method and the collocation method, where the obtained solution was compared with the numerical fourth-order Runge-Kutta solution. However, the present paper only introduces a new approach to obtain the exact solution of the concerned system and implements such exact solution as a reference to validate the published approximate solutions. Several remarks on the previously published results are observed and discussed in detail through tables… More >

Abstract The identification of brain tumors is multifarious work for the separation of the similar intensity pixels from their surrounding neighbours. The detection of tumors is performed with the help of automatic computing technique as presented in the proposed work. The non-active cells in brain region are known to be benign and they will never cause the death of the patient. These non-active cells follow a uniform pattern in brain and have lower density than the surrounding pixels. The Magnetic Resonance (MR) image contrast is improved by the cost map construction technique. The deep learning algorithm for differentiating the normal brain… More >

Abstract A numerical parameter mathematically derived from the graph structure is a topological index. The topological index is the first actual choice in QSAR research and these indices are used to build the correlation model between the chemical structures of various chemicals compounds. Here, we investigate some old degree-based topological indices like Randic index, sum connectivity index, ABC index, GA index, 1^st and 2^nd Zagreb indices, modified second Zagreb index, redefined version of 1^st, 2^nd and 3^rd Zagreb indices, hyper and augmented Zagreb indices, forgotten index and symmetric division degree index, and some new degree-based indices like SK index, SK₁ index,… More >

Abstract Emotion detection from the text is a challenging problem in the text analytics. The opinion mining experts are focusing on the development of emotion detection applications as they have received considerable attention of online community including users and business organization for collecting and interpreting public emotions. However, most of the existing works on emotion detection used less efficient machine learning classifiers with limited datasets, resulting in performance degradation. To overcome this issue, this work aims at the evaluation of the performance of different machine learning classifiers on a benchmark emotion dataset. The experimental results show the performance of different machine… More >

Abstract Human motion recognition plays a crucial role in the video analysis framework. However, a given video may contain a variety of noises, such as an unstable background and redundant actions, that are completely different from the key actions. These noises pose a great challenge to human motion recognition. To solve this problem, we propose a new method based on the 3-Dimensional (3D) Bag of Visual Words (BoVW) framework. Our method includes two parts: The first part is the video action feature extractor, which can identify key actions by analyzing action features. In the video action encoder, by analyzing the action… More >

Abstract Myocarditis has a variable clinical presentation and there is still debate regarding accurate diagnostic criteria. Adding to the controversy surrounding this diagnosis, there is no clear consensus for the treatment or ongoing follow‐up of patients with myocarditis. All of this makes the diagnosis and management of myocarditis a par‐ ticular challenge in the pediatric population. Furthermore, the literature with respect to this topic is dynamic and ever‐changing. In this review article, we aim to review and summarize the common clinical presentations of myocarditis, along with the latest recommendations for diagnostic criteria, treatment, and follow‐up of patients with myocarditis.

Abstract Objectives: This study assessed the frequency and utility of echocardiographic examination in patients with all forms of Ehlers‐Danlos syndrome and sought to iden‐ tify clinical variables associated with an abnormal echocardiogram.
Design/setting: This was a retrospective study of all patients carrying a diagnosis of Ehlers‐Danlos syndrome of any type who were evaluated by a pediatrician or pediatric subspecialist at a single tertiary medical center with an affiliated children’s hospital during the period January 2013 to December 2018.
Patients: Chart review was performed on all patients carrying a diagnosis of Ehlers‐ Danlos syndrome in the electronic medical record.
Outcome Measures: Data… More >

Abstract Objective: Patients with Trisomy 21 (T21) and single ventricle (SV) physiology present unique challenges compared to euploidic counterparts. This study reports postoperative and long‐term outcomes in patients with T21 and SV palliation.
Design: This retrospective cohort study from the Pediatric Cardiac Care Consortium (PCCC) included patients with T21 (<21 years old) that underwent surgical palliation for SV between 1982 and 2008 and control patients without known genetic anom‐ aly following Fontan palliation for similar diagnoses. Kaplan‐Meier survival plots were created based on death events obtained from the PCCC and by linkage with the National Death Index (NDI) and the Organ… More >

Abstract Objective: A significant body of patients who have undergone Mustard or Senning procedure require lifelong follow up. In this retrospective review, we examined the cohort of such patients currently attending our center.
Design: Patients who had undergone either Mustard or Senning procedure were identified. We retrospectively reviewed medical records, recorded demographic in‐ formation and data regarding the clinical state, NHYA class, cardiopulmonary exer‐ cise testing, NT‐proBNP measurement, and recent cardiac MRI findings.
Results: Forty‐six patients were identified, the mean age was 32.2 years (± 6.1 years), 67.4% were male. Thirty‐two patients (69.6%) had undergone a Senning procedure. The median length… More >
