Blind assessment for stereo images considering binocular characteristics and deep perception map based on deep belief network

© 2018 Elsevier Inc. In recent years, blind image quality assessment in the field of 2D image/video has gained the popularity, but its applications in 3D image/video are to be generalized. In this paper, we propose an effective blind metric evaluating stereo images via deep belief network (DBN). This method is based on wavelet transform with both 2D features from monocular images respectively as image content description and 3D features from a novel depth perception map (DPM) as depth perception description. In particular, the DPM is introduced to quantify longitudinal depth information to align with human stereo visual perception. More specifically, the 2D features are local histogram of oriented gradient (HoG) features from high frequency wavelet coefficients and global statistical features including magnitude, variance and entropy. Meanwhile, the global statistical features from the DPM are characterized as 3D features. Subsequently, considering binocular characteristics, an effective binocular weight model based on multiscale energy estimation of the left and right images is adopted to obtain the content quality. In the training and testing stages, three DBN models for the three types features separately are used to get the final score. Experimental results demonstrate that the proposed stereo image quality evaluation model has high superiority over existing methods and achieve higher consistency with subjective quality assessments

Plasmon-enhanced chiral absorption through electric dipole-electric quadrupole interaction

Enantioselective interactions of chiral molecules include distinct absorptions to opposite-handed circularly polarized light, known as chiral absorption. Traditionally, chiral absorption has been primarily attributed to electric dipole and magnetic dipole interaction with molecular chirality. However, this approach falls short for large molecules that support high-order multipolar components, such as electric quadrupole moment. Here, we introduce a theoretical model to study the chiral absorption of large molecules in the presence of plasmonic nanostructures. This model considers both electric dipole-magnetic dipole interaction and electric dipole-electric quadrupole interaction enhanced by a resonant structure. We numerically study such interactions of the chiral molecular solution in the vicinity of a nonchiral plasmonic nano-resonator. Our results show the distinct spectral information of the chiral media on- and off-resonance of the resonator

Data_Sheet_1_Code-switching costs from Chinese-English relative clauses processing.pdf

IntroductionThe source of costs is a primary concern in code-switching, yet a consensus has not yet been reached. This study investigates whether code-switching during syntactic processing in Chinese-English dual languages results in a cost.MethodsWe use Chinese and English relative clauses in either object (Experiment 1) or subject (Experiment 2, which has a more complex structure) positions to test the costs in syntactic processing. Forty-seven Chinese-English bilinguals and 17 English-Chinese bilinguals participated in acceptability judgment tests and self-paced reading experiments.ResultsThe statistical findings indicate that syntactic processing is a source of the costs incurred in code-switching, as evidenced by the code-switching costs observed in the head movement during relative clause comprehension.DiscussionThe outcomes are consistent with the implications of the 4-Morpheme Model and the Matrix Language Framework. Additionally, the experiment shows that the processing of relative clauses depends on the underlying structures, which is consistent with the Dependency Locality Theory.</p

Laboratory Evaluation of Placement Behavior of Microgels for Conformance Control in Reservoirs Containing Superpermeable Channels

Gel treatment has been proven an effective method to attack excessive water production in many mature oilfields. However, not all of the application projects have successful stories. The effectiveness of a gel treatment largely depends on the transport and placement behavior of gel materials in reservoirs to be treated. In this work, we carried out systematic studies to investigate the transport, placement, water-blocking ability, fluid diversion and sweep improvement, and matrix damage effect of micrometer-sized preformed particle gels (microgels) in reservoirs containing superpermeable (super-K) channels. The impact of the channel/matrix permeability contrast and the particle/pore size ratio in the channels and in the matrices was studied. The favorable conditions for gel treatments were identified. The results show that the microgel particles selectively penetrate, place in, and effectively shut off the super-K channels under proper conditions. The sweep improvement after gel treatments was evaluated through chemical tracer tests. The results clearly demonstrate delayed breakthrough, fluid diversion, and increased swept volume of the subsequent flooding fluid. In the experiments, the sweep improvement was in the range of 0.25–0.43 total pore volumes. A higher sweep improvement was achieved as the permeability contrast was higher (i.e., the reservoir was more heterogeneous). To achieve both good injectivity and water-blocking efficiency for the tested microgels, the particle/pore size ratio in the channel should be below 2. Meanwhile, the particle/pore ratio in the matrices should be kept above 5 to avoid significant damage to the matrices. The results of this study provide support for gel product selection and successful gel treatment designs and implementations

Enantioselective Cross-Coupling of <i>meso</i>-Epoxides with Aryl Halides

The first enantioselective cross-electrophile coupling of aryl bromides with <i>meso</i>-epoxides to form <i>trans</i>-β-arylcycloalkanols is presented. The reaction is catalyzed by a combination of (bpy)­NiCl₂ and a chiral titanocene under reducing conditions. Yields range from 57 to 99% with 78–95% enantiomeric excess. The 30 examples include a variety of functional groups (ether, ester, ketone, nitrile, ketal, trifluoromethyl, sulfonamide, sulfonate ester), both aryl and vinyl halides, and five- to seven-membered rings. The intermediacy of a carbon radical is strongly suggested by the conversion of cyclooctene monoxide to an aryl [3.3.0]­bicyclooctanol

Scalar Diffraction Analysis Of Dispersion In Low-Index Thin Flat Lenses

We analyze the dispersion property of low-index thin lenses by using scalar diffraction and finite difference time domain (FDTD) methods. We compare the dispersion results obtained by using these methods with reported experimental results, and the well-known analytical formula for focal length (f) of diffractive lenses as a function of wavelength ({\lambda}),f({\lambda})=(f_0 {\lambda}_0)/{\lambda},where f_0 is the designed focal length for wavelength {\lambda}_0. We show that when the analytical formula is applied to thin flat lenses with low-refractive index, the results are accurate for small numerical aperture (NA) up to 0.2. For larger NA, the error between the analytical approximation and the FDTD analysis remains around 8% over a wide range of NA
