In this paper, a novel formulation for nonlinear model predictive control (MPC) has been proposed incorporating the extended Kalman filter (EKF) control concept using a purely data-driven artificial neural network (ANN) model based on measurements for supervisory control. The proposed scheme consists of two modules focusing on online parameter estimation based on past measurements and control estimation over control horizon based on minimizing the deviation of model output predictions from set points along the prediction horizon...

With current research focus to interconnect the molecular communication environment with external environment, it is imperative to design external devices working on molecular communication schemes to be interfaced with in-vivo molecular network. Recently, efforts have been made to integrate molecular communication with Lab-on-chip (LOC); one of the techniques used in LOC for manipulation and transportation of molecules is Dielectrophoresis (DEP). We propose the use of DEP in molecular communication to maintain in-sequence delivery of molecules...

PURPOSE: To determine the local government area (LGA)-level prevalence of trachoma in all 34 LGAs of Katsina State. METHODS: A population-based prevalence survey was conducted in each LGA of Katsina State, using the Global Trachoma Mapping Project methodology. We used a 3-stage cluster random sampling strategy to select 25 households from each of 25 clusters. We examined all residents of selected households aged 1 year and older for the clinical signs of trachomatous inflammation-follicular (TF), trachomatous inflammation-intense and trichiasis, using the World Health Organization (WHO) simplified grading scheme...

We investigate a spatial model of growth of a tumor and its sensitivity to radiotherapy. It is assumed that the radiation dose may vary in time and space, like in intensity modulated radiotherapy (IMRT). The change of the final state of the tumor depends on local differences in the radiation dose and varies with the time and the place of these local changes. This leads to the concept of a tumor's spatiotemporal sensitivity to radiation, which is a function of time and space. We show how adjoint sensitivity analysis may be applied to calculate the spatiotemporal sensitivity of the finite difference scheme resulting from the partial differential equation describing the tumor growth...

Using existing longitudinal data from 570 infants in the Maternal Lifestyle Study, we explored the predictive value of maternal and infant affect and maternal vocalizations during 2 minutes of face-to-face interactions at 4 months on IQ scores at 4.5 and 7 years. After controlling for demographic factors, maternal depression, and prenatal drug exposure, maternal positive affect and maternal positive vocalizations emerged as predictors of both verbal and performance IQ at 4.5 and 7 years. Although infant positive affect during the interaction with the mother was not predictive of these outcome measures, infant positive affect towards an examiner predicted verbal but not performance IQ at 4...

RNA enzymes serve as a potentially powerful platform from which to design catalysts and engineer new biotechnology. A fundamental understanding of these systems provides insight to guide design. The hepatitis delta virus ribozyme (HDVr) is a small, self-cleaving RNA motif widely distributed in nature, that has served as a paradigm for understanding basic principles of RNA catalysis. Nevertheless, questions remain regarding the precise roles of divalent metal ions and key nucleotides in catalysis. In an effort to establish a reaction mechanism model consistent with available experimental data, we utilize molecular dynamics simulations to explore different conformations and metal ion binding modes along the HDVr reaction path...

Concurrent recording of electroencephalography (EEG) during transcranial magnetic stimulation (TMS) is an emerging and powerful tool for studying brain health and function. Despite a growing interest in adaptation of TMS-EEG across neuroscience disciplines, its widespread utility is limited by signal processing challenges. These challenges arise due to the nature of TMS and the sensitivity of EEG to artifacts that often mask TMS-evoked potentials (TEP)s. With an increase in the complexity of data processing methods and a growing interest in multi-site data integration, analysis of TMS-EEG data requires the development of a standardized method to recover TEPs from various sources of artifacts...

 Evidence-based medicine (EBM) is fundamental to ensuring high-quality medical care. It requires systematic reviews and meta-analyses to synthesize diverse information available from individual clinical studies. However, the literature reviewed may represent an incomplete and selective set of research findings, which could lead to publication/reporting biases and distort the true picture of research as a whole. Prospective registry of all clinical trials in the world is mandatory to reduce the biases, which have been disclosed on the International Clinical Trials Registry Platform (ICTRP) of the World Health Organization (WHO) since 2007...

INTRODUCTION: Ventral hernia repair (VHR) is a commonly performed surgical procedure. Unfortunately, long term prospective information about quality of life and outcomes after VHR has been challenging to obtain. Decoupling follow up from clinical visits via patient reported outcomes (PROs) has been proposed as a means of achieving better long term assessments after VHR. The Americas Hernia Society Quality Collaborative (AHSQC) is a national quality improvement (QI) effort in hernia repair which uses PROs to obtain long term follow up...

Inflammation has long been associated with the thyroid and with thyroid cancers, raising seminal questions about the role of the immune system in the pathogenesis of advanced thyroid cancers. With a growing understanding of dynamic tumour-immune cell interactions and the mechanisms by which tumour cells evade antitumour immunity, the field of cancer immunotherapy has been revolutionised. In this Review, we provide evidence to support the presence of an antitumour immune response in advanced thyroid cancers linked to cytotoxic T cells and NK cells...

An increase in narcolepsy incidence was noted after the novel pandemic influenza of 2009, leading to further interest in risk factors associated with this disease. However, there is limited data on the epidemiology of narcolepsy, particularly in the adult population. Therefore, we sought to examine narcolepsy incidence rates in the United States and describe associated characteristics. We performed a population based epidemiologic study of active duty military personnel. All outpatient clinics in the continental United States providing care for active duty military between 2004 through 2013 were included utilizing existing databases...

OBJECTIVE: Epidemiological evidence suggests that work stress is associated with suicidal ideation (SI). However, only few studies in this area have drawn on well-established theoretical work stress models (i.e., the job-demand-control [JDC] model, the effort-reward-imbalance [ERI] model, and the model of organizational injustice [OJ]). Utilization of such models allows though for theory-based assessments and workplace interventions. Since evidence on those models' relationship with suicide-related outcomes is currently inconclusive (with regard to JDC), markedly sparse (OJ) or lacking (ERI), we aimed to provide additional or initial evidence...

PURPOSE: Toward an efficient clinical management of hepatocellular carcinoma (HCC), we propose a classification framework dedicated to tumor necrosis rate estimation from dynamic contrast-enhanced CT scans. Based on machine learning, it requires weak interaction efforts to segment healthy, active and necrotic liver tissues. METHODS: Our contributions are two-fold. First, we apply random forest (RF) on supervoxels using multi-phase supervoxel-based features that discriminate tissues based on their dynamic in response to contrast agent injection...

Racial and ethnic minorities are at high risk for developing posttraumatic stress disorder (PTSD) after experiencing a traumatic event and are less likely to receive evidence-based treatment for their symptoms. There is a growing body of literature showing that culturally appropriate interventions result in greater uptake, symptom reduction, and sustained treatment gains. This article review explores new findings in the cultural understanding of PTSD among racial and ethnic minorities. We first review recent advances in the understanding of PTSD symptomotology...

OBJECTIVE: In March 2014, India, the country with historically the highest burden of polio, was declared polio free, with no reported cases since January 2011. We estimate the health and economic benefits of polio elimination in India with the oral polio vaccine (OPV) during 1982-2012. METHODS: Based on a pre-vaccine incidence rate, we estimate the counterfactual burden of polio in the hypothetical absence of the national polio elimination program in India. We attribute differences in outcomes between the actual (adjusted for under-reporting) and hypothetical counterfactual scenarios in our model to the national polio program...
