In this paper, we present the PerceptIn Visual Inertial Odometry (PI-VIO), a tightly-coupled filtering-based stereo VIO system using both points and lines. Line features help improve system robustness in challenging scenarios when point features cannot be reliably detected or tracked, e.g. lowtexture environment or lighting change. In addition, we propose a new lightweight filtering-based loop ...

Harmonization of satellite imagery provides a good opportunity for studying land surface temperature (LST) as well the urban heat island effect. However, it is challenging to use harmonized data study LST due systematic bias between LSTs from different satellites, which highly influenced by sensor differences and compatibility retrieval algorithms. To fill this research gap, proposes comparison...

Identity verification systems that use a mono modal biometric always have to contend with sensor noise and limitations of the feature extractor and matcher, while combining information from different biometrics modalities may well provide higher and more consistent performance levels. However, an intelligent scheme is required to fuse the decisions produced by the individual sensors. This paper...

Speckle filtering and edge detection are fundamental techniques for polarimetric synthetic aperture radar (PolSAR) image analysis. In this paper, based on complex Wishart distribution and the similarity test of the covariance matrix, a completely adaptive speckle filtering is proposed. Meanwhile, a new edge indicator named similar pixel number is developed. This indicator shows great sensitivit...

Myocardial injury in mammals leads to heart failure through pathological cardiac remodelling that includes hypertrophy, fibrosis and ventricular dilatation. Central to this is inability of the mammalian cardiomyocyte to self-renew due to entering a quiescent state after birth. Modulation of the cardiomyocyte cell-cycle after injury is therefore a target mechanism to limit damage and potentiate ...

Octafluorocyclobutane, c-C4F8, and its derivatives are regarded as promising replacements of insulation gaseous SF6, which are currently widely used in electric equipment but suffer greatly from its greenhouse effect. Based on the recent finding that the dielectric and thermodynamics properties of insulating gases are greatly dependent on the molecule's microscopic electronic and vibrational pa...

The 2-mono and 2,6-disubstituted methyl-1,4-dihydropyridines were synthesized by reaction of morpholine, thiophenol, 8-hydroxyquinoline, 2-naphthol and 2-mercopto-1-methyl imidazole with the 2-mono bromo and 2,6-dibromo-1,4-dihidropyridines.

A C++ language-based software tool for retrieving land surface temperature (LST) from the data of Landsat TM/ ETM+ band6 is developed. It has two main functional modules: (1) Three methods to compute the ground emissivity based on land use/cover classification image, NDVI image and the ratio values of vegetation and bare ground and (2) Converting digital numbers (DNs) from TM/ETM+ band6 to LST....

The abundance of nuclear plastid DNA-like sequences (NUPTs) in nuclear genomes can vary immensely; however, the forces responsible for this variation are poorly understood. "The limited transfer window hypothesis" predicts that species with only one plastid per cell will have fewer NUPTs than those with many plastids per cell, but a lack of genome sequence data from monoplastidic species has ma...

BACKGROUND Malaria and dengue are two of the most common vector-borne diseases in the world, but co-infection is rarely described, and immunologic comparisons of co-infection with mono-infection are lacking. METHODOLOGY AND PRINCIPAL FINDINGS We collected symptom histories and blood specimens from subjects in a febrile illness surveillance study conducted in Iquitos and Puerto Maldonado, Peru...
