When the first cleavage plane, the second cleavage plane, the third cleavage plane, and the fourth cleavage plane are respectively observed using a differential interference phase contrast microscope, the first strip pattern is observed in at least one of the first cleavage plane, the second cleavage plane, the third cleavage plane, and the fourth cleavage plane. A direction from the first main surface toward the second main surface is set as a first direction. Among the intersection points of the first strip pattern and the outer peripheral surface, the intersection point closest to the first main surface in the first direction is set as an origin point. A direction perpendicular to the first direction and toward the central axis from the origin point is set as a second direction. When a value obtained by dividing the distance from the origin in the first direction by the width of the first band-shaped pattern in the second direction is set as z, and a value obtained by dividing the distance from the origin in the second direction by the width is set as x, the first band-shaped pattern is approximated as a cubic function, the cubic function is represented by mathematical formula 1.

Dual resonance pattern reconfigurable antennas for sensing and communication are disclosed. A dual resonance pattern reconfigurable antenna includes a substrate, a patch antenna, a trace assembly that extends around a perimeter of the patch antenna, and a PIN diode. The trace assembly includes a first trace and a second trace. The first trace extends along a first trace length of the first side perimeter and is separated from the first side perimeter. The second trace includes a second trace top side segment that extends along the top side perimeter. A first gap separates the second trace from the first trace. The PIN diode is connected between the first trace and the second trace. The antenna is reconfigurable between a first biasing state and a second biasing state. The PIN diode is in an ON-state in the first biasing state. The PIN diode is an OFF-state in the second biasing state.

An abrasive disc sheet article having annular band patterns of vitrified abrasive particle agglomerate molded islands attached to a flexible disc backing is used for high-speed water-spray cooled abrading and polishing parts. Hydroplaning is prevented as excess coolant water flows around the islands instead of forming a thick water film that separates the island abrasive and the parts. Vitrification encapsulates diamond abrasive particles in glass to strongly support them against abrading forces as the expensive diamond particles are progressively worn down. Solvent-based adhesives are used to mold the islands where evaporation of the solvent results in porous islands that provide controlled rates of island eroding. A porous filler material attached to the disc backing between the island structures carries water to contact the wafer surface and cool it during abrading. Interchangeable discs having different abrasive particle sizes are quickly attached with vacuum to flat rotatable platens.

This invention belongs to the field of machine learning technology, specifically relating to a machine learning-based intelligent identification method for immunofixation electrophoresis bands. The method uses a single band as the smallest identification unit, training the model with manually labeled normal and abnormal bands to accurately identify the features of each band. Furthermore, the model automatically generates different band patterns based on the identified abnormal bands, achieving automated transformation from single band identification to complete band pattern analysis. This strategy significantly reduces the dependence on large-sample training data, requiring only a relatively small amount of high-quality labeled data to achieve good results. In addition, this invention validated the model in multi-center samples, and by further constructing an online identification system, it achieved intelligent processing of the entire immunofixation electrophoresis process, from pattern recognition to band pattern interpretation.
