Abstract We present a comprehensive analysis of the submissions to first edition Endoscopy Artefact Detection challenge (EAD). Using crowd-sourcing, this initiative is step towards understanding limitations existing state-of-the-art computer vision methods applied endoscopy and promoting development new approaches suitable for clinical translation. routine imaging technique detection, diagnosis treatment diseases in hollow-organs; esophagus, stomach, colon, uterus bladder. However nature...
The supramolecular approach of π-conjugated polymers imparts excellent self-assembly behaviour to construct organogels and simultaneously affords superstructured thin films, which allow for uncovering structure–function relationships. Herein, a polyfluorene-based poly(tertiary alcohol), poly(9-(4-(octyloxy)phenyl)-2,7-fluoren-9-ol) (PPFOH), has been synthesized investigate the organic solvent effect on gelation at room temperature. driving force hydrogen bonding π–π stacking interactions in...
Nanotechnology not only opens up the realm of nanoelectronics and nanophotonics, but also upgrades organic thin-film electronics optoelectronics. In this review, we introduce polymer semiconductors plastic briefly, followed by various top-down bottom-up nano approaches to electronics. Subsequently, highlight progress in polyfluorene-based nanoparticles nanowires (nanofibres), their tunable optoelectronic properties as well applications light-emitting devices, solar cells, field-effect...
Controlled synthesis of polyhedral crystals has acquired intense attention over the past few years due to their potential electrical and optical properties special functionalities for integrated devices. In this work, endocyclic molecules triptycene are self-assembled into pretty uniform polyhedra quasi-decahedra well-defined nanosheets via assistance P123 CTAB, respectively. These nanostructures have been clearly investigated by using field emission scanning electron microscopy (FESEM),...
Xtacking™ is a novel 3D (three-dimensional) NAND flash architecture, in which memory cells and peripheral circuits are bonded by millions of pairs small-pitch metal vias. Consequently, its bonding interface reliability attracts great interest. In this paper, we conducted test both structure level product level. test, the layer showed stable electrical properties after ultra-long time thermal or humidity stress (e.g., 7000hrs), much longer than common industry requirement 1000hrs)....
Optical coherence tomography (OCT) is widely used in computer-aided medical diagnosis of retinal pathologies. Deep convolutional network has been successfully applied to detect lesions from OCT images. Different imaging devices inevitably cause variation the distribution between training phase and testing phase, which will lead extremely reduction on model performance. Most existing unsupervised domain adaptation methods are mainly focused lesion segmentation, there few studies detection...
Backside (BS) interconnects has shown significant advantages in 3D integral circuits for tackling the technology scaling induced frontside (FS) back-end-of-line (BEOL) routing congestion and RC delay challenge. As a representative BS architecture, Xtacking ® 1.0 & 2.0 innovated by YMTC employs one Al metal layer at backside of memory cell wafer as interconnect signal transfer. In this paper, we exploit effect silicon substrate to stress migration (SM) reliability such interconnects, offer...
Surveillance cameras have been widely used in urban environments and are increasingly rural ones. Such mostly for security, but they can be applied to the problem of furnishing fine-grained measurements predictions precipitation intensity. In this study, we formulated a stacked order-preserving (OP) learning framework train network using time-series data. We constructed an OP module, which uses three-dimensional (3D) convolution operation extract features with spatial temporal information...
In this work, we propose a new framework, called Geospatial-temporal Convolutional Neural Network (GT-CNN), and construct the video-based geospatial-temporal precipitation dataset from surveillance cameras of eight weather stations (sampling points) to recognize intensity. GT-CNN has three key modules: (1) Geospatial module, (2) Temporal (3) Fusion module. geospatial extract information each sampling point simultaneously, that is used relationships using LSTM between various points. temporal...
A general scheme for the investigation of scattering by a chiral sphere under arbitrary monochromatic laser beam illumination is presented. The scattered and internal fields are expanded using appropriate spherical vector wave functions, their expansion coefficients determined boundary conditions projection method. Targeting multiple incidence forms such as Gaussian beam, Hermite–Gaussian doughnut mode zero-order Bessel influence propagation near-surface intensity field analyzed. These...
There always are some breakpoints and bifurcation points in measured data of target radiation scattering characteristics, which have a great impact on the effectiveness. While among existed pre-processing methods, original point becomes more prominent or makes part signal. These methods will an effect subsequent extraction recognition for features. A method based multi-threshold effectively removes numerical singularity enhances signal to noise ratio without changing is given this paper.
