Spatiotemporal explicit information on paddy rice distribution is essential for ensuring food security and sustainable environmental management. Paddy rice mapping algorithm through the Combined Consideration of Vegetation phenology and Surface water variations (CCVS) has been efficiently applied based on the 8day composites time series datasets. However, the great challenge for phenology-based algorithms introduced by unpromising data availability in middle/high spatial resolution imagery, such as frequent cloud cover and coarse temporal resolution, remained unsolved...

Objective: To assess the accuracy of five different computed tomography (CT) scanners for the evaluation of the oropharynx morphology. Methods: An existing cone-beam computed tomography (CBCT) data set was used to fabricate an anthropomorphic phantom of the upper airway volume that extended from the uvula to the epiglottis (oropharynx) with known dimensions (gold standard). This phantom was scanned using two multi-detector row computed tomography (MDCT) scanners (GE Discovery CT750 HD, Siemens Somatom Sensation) and three CBCT scanners (NewTom 5G, 3D Accuitomo 170, Vatech PaX Zenith 3D)...

OBJECTIVE: Self-management is an essential part of achieving asthma control and improving long-term outcomes. While guidelines recommend the provision of written asthma action plans (AAPs), few patients presenting to emergency departments (ED) have one. This systematic review examined if individualized written AAPs reduce relapses in adults following an ED visit for acute asthma. DATA SOURCES: Comprehensive searches of seven electronic databases and grey literature were conducted...

Robotically guided knee arthroplasty systems generally require an individualized, preoperative 3D model of the knee joint. This is typically measured using Computed Tomography (CT) which provides the required accuracy for preoperative surgical intervention planning. Ultrasound imaging presents an attractive alternative to CT, allowing for reductions in cost and the elimination of doses of ionizing radiation, whilst maintaining the accuracy of the 3D model reconstruction of the joint. Traditional phased array ultrasound imaging methods, however, are susceptible to poor resolution and signal to noise ratios (SNR)...

BACKGROUND: Use of high-risk medications in the elderly (HRME) and drug-disease (Rx-DIS) interactions in the elderly, as defined by the Healthcare Effectiveness Data and Information Set (HEDIS) Measures, are significantly associated with mortality, hospital admission, and need for emergency care. No published studies to date evaluate interventions to reduce the use of HEDIS-defined HRME, although many studies have postulated a beneficial effect of such interventions. OBJECTIVE: To evaluate the effect of pharmacist interventions on use of HRME and Rx-DIS interactions in the outpatient elderly population...

OBJECTIVES: Calcification of the torus tubarius has been rarely reported in the literature. Histopathologic studies have previously described cases of Eustachian tube calcification and cite an association with increasing patient age. The purpose of this study was to examine the prevalence of torus tubarius calcification and potential clinical significance on an unrestricted patient population using thin-section computed tomography (CT), which has not been previously reported. METHODS: After the institutional review board approval, 1571 consecutive patients who underwent noncontrast head CT between January 2011 and July 2011 were retrospectively reviewed for torus tubarius calcification...

Interaction of liquids with surfaces is ubiquitous in our physical environment as well as many engineering applications. Recent advances on this topic have not only provided us with valuable insight into nature's design, but also enabled improved fluidic manipulation for liquid-based printing applications such as bio-microarrays for protein and DNA sequencing, multicolor polymer-based LED displays, inkjet printing, and solder droplet printing, among others. For example, droplet contact lines which are typically circular on a smooth and homogenous surface when deposited on a microdecorated surface may take various common polygonal shapes such as squares, rectangles, hexagons, octagons and dodecagons...

The aim of this study was to determine the factors that go into a highly reliable estimate of radon exposure levels for use in setting up the case-control study. To this end, the present study conducted a multi-faceted investigation of the distribution of radon concentrations in the bedrooms and living rooms of 400 households in the target areas during the winter months from December 2014 to February 2015. We determined that taking the mean value of the radon concentration levels detected in the bedroom and living room as the representative value of residential concentration is appropriate, given the usability of previous research data and the difference in the concentration levels between the two...

A Periodic System was proposed for the elements 1-172 by Pyykkö on the basis of atomic and ionic calculations. In it, the elements 121-138 were nominally assigned to a 5g row. We now perform molecular, relativistic four-component DFT calculations and find that the hexafluorides of the elements 125-129 indeed enjoy occupied 5g states.

BACKGROUND: The contents of the guinea pig distal colon consist of multiple pellets that move anally in a coordinated manner. This row of pellets results in continued distention of the colon. In this study, we have investigated quantitatively the features of the neurally dependent colonic motor patterns that are evoked by constant distension of the full length of guinea-pig colon. METHODS: Constant distension was applied to the excised guinea-pig by high-resolution manometry catheters or by a series of hooks...

Despite limited pharmacokinetic (PK) data, dexmedetomidine is increasingly being used off-label for sedation in infants. We aimed to characterize the developmental PK changes of dexmedetomidine during infancy. In this open-label, single-center PK study of dexmedetomidine in infants receiving dexmedetomidine per clinical care, ≤10 blood samples per infant were collected. A set of structural PK models and residual error models were explored using nonlinear mixed-effects modeling in NONMEM. Covariates including postmenstrual age (PMA), serum creatinine, and recent history of cardiac surgery requiring cardiopulmonary bypass were investigated for their influence on PK parameters...

PURPOSE: Bone fracture risk assessed ancillary to positron emission tomography with computed tomography co-registration (PET/CT) could provide substantial clinical value to oncology patients with elevated fracture risk without introducing additional radiation dose. The purpose of our study was to investigate the feasibility of obtaining valid measurements of bone mineral density (BMD) and finite element analysis-derived bone strength of the hip and spine using PET/CT examinations of prostate cancer patients by comparing against values obtained using routine multidetector-row computed tomography (MDCT) scans-as validated in previous studies-as a reference standard...

INTRODUCTION: A wide range of psychiatric disorders are common in young children, especially in those at high risk because of a parent with a unipolar or bipolar mood disorder in the United States. Yet in part because most children are seen in primary care, these illnesses are often not recognized or treated in a timely fashion. To begin to address this problem, we started the Child Network. METHODS: The Child Network is for parents of children age 2-12 with mood or behavioral symptoms or at high risk for them...

Using a bull's-eye hierarchical mapping technique (HMT), the present study examined placement of parents in adults' attachment networks over time. We hypothesized that attachment style would predict distance at which network members (mother, father, and romantic partner) would be placed from the core-self over time. Participants completed the HMT on two occasions, 12 months apart. Concurrently and over time, fathers were placed further from the core-self than mothers. Attachment style explained unique variance, beyond that accounted for by individual and relationship characteristics...

Limb synovial joints are composed of distinct tissues, but it is unclear which progenitors produce those tissues and how articular cartilage acquires its functional postnatal organization characterized by chondrocyte columns, zone-specific cell volumes and anisotropic matrix. Using novel Gdf5(CreERT2) (Gdf5-CE), Prg4-CE and Dkk3-CE mice mated to R26-Confetti or single-color reporters, we found that knee joint progenitors produced small non-migratory progenies and distinct local tissues over prenatal and postnatal time...
