Similarity Evaluation of Patent Drawings using ResNet and SIFT
Journal of Intellectual PropertyThe study of the similarity evaluation and retrieval of patent documents is critical not only for the efficient management of patent literature, but also for the rapid and effective collection of information in industrial and technological fields. Patent

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.Protonic ceramic fuel cells offer a promising route to generate power efficiently but face critical challenges in achieving industrially viable activity and stability at their cathodes in CO2‐containing air. This report proposes a new cathode material design strategy to enable the cathode to be both catalytically active and CO2 tolerant through the ...

Irregularity in sifted sequences
Journal of Number Theory, 1972 AbstractK. F. Roth (Acta Arith. 9 (1964), 257–260) considered the distribution of a sequence N of distinct positive integers not exceeding N among the residue classes for each modulus not exceeding Q. He showed that a certain variance was >ρ(1 − ρ) Q2N, where ρ was the density of the sequence, implying that N is not too evenly distributed among the ...

Advanced Functional Materials, EarlyView.Carbon nanomembranes with ultra‐thin Al2O3 functionalization are less than 15 nm thin and exhibit outstanding permeation performance with a water vapor/nitrogen selectivity higher than 1 × 104, twice that of pristine CNMs, and an exceptionally high water vapor permeation rate for potential applications in air dehumidification.

A feature extraction algorithm based on corner and spots in self-driving vehicles
Journal of Hebei University of Science and Technology, 2017 To solve the poor real-time performance problem of the visual odometry based on embedded system with limited computing resources, an image matching method based on Harris and SIFT is proposed, namely the Harris-SIFT algorithm.

An elementary characterisation of sifted weights [PDF]
arXiv, 2014 Sifted colimits (those that commute with finite products in sets) play a major role in categorical universal algebra. For example, varieties of (many-sorted) algebras are precisely the free cocompletions under sifted colimits of (many-sorted) Lawvere theories.

Advanced Functional Materials, EarlyView.The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.
