Optical coherence tomography (OCT) is a well-established image modality in ophthalmology and used daily the clinic. Automatic evaluation of such datasets requires an accurate segmentation retinal cell layers. However, due to naturally low signal noise ratio resulting bad quality, this task remains challenging. We propose automatic graph-based multi-surface algorithm that internally uses soft constraints add prior information from learned model. This improves accuracy increase robustness...
Advances in proteomics and sequencing have highlighted many non-annotated open reading frames (ORFs) eukaryotic genomes. Genome annotations, cornerstones of today's research, mostly rely on protein prior knowledge ab initio prediction algorithms. Such algorithms notably enforce an arbitrary criterion one coding sequence (CDS) per transcript, leading to a substantial underestimation the potential eukaryotes. Here, we present OpenProt, first database fully endorsing polycistronic model genomes...
In conventional two-photon excitation fluorescence microscopy, the numerical aperture of objective determines lateral resolution and depth field. some situations, as with functional imaging dynamic events distributed in live biological tissue, an improved temporal is needed; a consequence, it imperative to use optics high field simultaneously image objects at different axial positions. With microscope objective, increasing achieved expense resolution. To overcome this limitation, we have...
Barium titanate (BT) ceramics with Ba/Ti ratios of 0.95 and 1.00 were synthesized using spark plasma sintering (SPS) technique. Dielectric spectroscopy (frequency range from 40 Hz to 1 MHz temperature 300 K 30 K) was performed on those (SPS BT). SPS BT showed extremely high permittivity up ∼105, which can be referred as colossal permittivity, relatively low dielectric loss ∼0.05. Data analyses following Debye relaxation universal response models indicate that the origin in is result a...
The design of a nonlinear Luenberger observer for an extended system resulting from parameterized linear SISO (single-input single-output) is studied. From observability assumption the system, existence such concluded. In second step, novel algorithm identification suggested. Compared to adaptive observers available in literature, it has advantage be low dimension and admit strict Lyapunov function.
Choline is a vital micronutrient that can be utilized in the formation of betaine and multiple phospholipids. In this study, we aimed to confirm, expand on previous findings, how choline impacts embryos from first 7 days development affect postnatal phenotype. Bos indicus were cultured choline-free medium (termed vehicle) or supplemented with 1.8 mM Blastocyst-stage transferred into crossbred recipients. Once born, calves evaluated at birth, 94 d, 178 d weaning (average age = 239 d)....
This article aims at promoting cooperation between drying and control communities in the future. Indeed, with a review of 71 relevant publications all dealing aspects drying, this shows that use tools really started to emerge applications only since 1979. In second phase around 1998, new trends based on more advanced concepts have also appeared control. clearly is reality many opportunities exist enhance industrial performance via efficient operation.
Monodisperse quaternary chalcopyrite Cu2CoSnS4 colloidal quantum dots have been synthesized by acid peptization of a tailored precursor displaying loosely packed, ultrafine primary crystallites. Well-defined peaks shifted to higher energy compared the bulk band gap value were observed on UV-Vis absorption curve consistent with confinement behavior. First investigations room temperature time resolved photoluminescence (TRPL) spectroscopy suggest that emission does not arise from...
In recent years, waste heat recovery (WHR) systems based on Rankine cycles have been the focus of intensive research for transport applications, as they seem to offer considerable potential fuel consumption reduction.
