DOI: 10.1063/5.0258152
Abstract: Optical spatial differentiations hold the capability of ultrahigh speed and low power consumption, providing an efficient solution for edge detection, feature extraction, and pattern recognition. However, existing optical spatial differentiators predominantly focus on integer-order operations,… read more here.

DOI: 10.1080/13658816.2025.2511227
Abstract: Abstract AI foundation models have demonstrated some capabilities for the understanding of geospatial semantics. However, applying such pre-trained models directly to geospatial datasets remains challenging due to their limited ability to represent and reason with… read more here.

DOI: 10.1364/ol.473999
Abstract: We theoretically propose topological spatial differentiators by the normal-incidence reflection of light. Firstly, a three-dimensional propagation model is established for the light normally incident on the interface between two media. It is found that due… read more here.

DOI: 10.17863/cam.48075
Abstract: Research in psychology on reasoning has often been restricted to relatively inexpressive statements involving quantifiers. This is limited to situations that typically do not arise in practical settings, such as ontology engineering. In order to… read more here.
