OBJECTIVE To increase discriminatory accuracy (DA) for emergency cesarean sections (ECSs). STUDY DESIGN We prospectively collected data on and studied all 6,157 births occurring in 2014 at four public hospitals located in three different autonomous communities of Spain. To identify risk factors (RFs) for ECS, we used likelihood ratios and logistic regression, fitted a classification tree (CTR...
This paper presented a rigorous mathematical model based on orbital parameters for correction of the geo-rectified images such as Ikonos Geo, where the geometry of image at the time of imaging is lost and minimum information regarding the satellite movement in its orbit is available. Based on this model, the geo-rectified image is converted back to its geometry at the time of imaging at first. ...
The stochastic trajectory-based (Lagrangian) approach has gained increasing importance and sophistication in atmospheric transport and dispersion modelling over the last few decades. State-of-the-art Lagrangian particle dispersion model (LPDMs) are used to compute trajectories of a large number of ‘marked’ particles and numerically simulate the dispersion of a pollutant (passive tracer) in the ...
Down regulation of mRNA translation is an important problem in various bio-medical domains ranging from developing effective medicines for tumors and for viral diseases to developing attenuated virus strains that can be used for vaccination. Here, we study the problem of down regulation of mRNA translation using a mathematical model called the ribosome flow model (RFM). In the RFM, the mRNA mol...
A toolbox of methods must be available for the remediation lakes and water bodies suffering from eutrophication. One method suggested is hypolimnetic withdrawal based on a closed-circuit system. Prior to start pilot-scale test at Lake Hönsan, Sweden, laboratory trial with containers filled bottom sediment this lake was performed. peristaltic pump distributed equal volume four columns, two glass...
In this paper, a novel and efficient photonic-assisted remote frequency measurement (RFM) system with significantly simplified structure flexible operation range is proposed. system, the antenna unit (RAU) central station (CS) are separated to ensure concealment safety of signal processing unit. At RAU, unknown radio (RF) modulated by dual-polarization dual-drive Mach–Zehnder modulator (DPol-DM...
Translation is a crucial step in gene expression. During translation, macromolecules called ribosomes “read” the mRNA strand in a sequential manner and produce a corresponding protein. Translation is known to consume most of the cell’s energy. Maximizing the protein production rate in mRNA translation, subject to the bounded biomolecullar budget, is thus an important problem in both biology and...
Late-life depression (LLD) is a common disorder associated with emotional distress, cognitive impairment and somatic complains. Structural abnormalities have been suggested as one of the main neurobiological correlates in LLD. However the relationship between these structural abnormalities and altered functional brain networks in LLD remains poorly understood. 15 healthy elderly comparison subj...
High-resolution satellite imagery is expected to be a major source of 3D measurement of ground, especially automatic stereo plotting to generate DEM by stereo matching technology is highly required. Epipolarity is a very useful concept in processing stereo imagery, and it has been widely used in process images captured by frame cameras. Different from perspective image, every scan line of linea...
With very high resolution satellite (VHRS) imagery of 0.5 m, WorldView-2 (WV02) satellite images have been widely used in the field of surveying and mapping. However, for the specific WV02 satellite image geometric orientation model, there is a lack of detailed research and explanation. This paper elaborates the construction process of the WV02 satellite rigorous sensor model (RSM), which consi...
