Abstract: The present disclosure relates to a multi-cutting-edge diamond composite, including a columnar hard alloy substrate (102) and a diamond composite layer (101), the diamond composite layer (101) being disposed at a top end of the hard alloy substrate (102), wherein a circumferential edge of a top end of the diamond composite layer (101) is provided with at least two segments of different chamfers (103, 104) to form different cutting edges. By providing different chamfers on the circumferential edge of the top end of the diamond composite layer, multiple cutting edges are formed in the circumferential direction of an end face of the diamond composite, such that different edges of the same composite sheet have different attacking abilities and impact resistance abilities.

Abstract: A process for thin strip production integrates continuous casting and rolling, with steps including continuous casting, rough rolling, induction heating, finish rolling, laminar cooling, high-speed shearing, and coiling. A key feature is the in-line heating between casting and rough rolling, where wide surfaces, narrow surfaces, and corners of the casting blank are heated simultaneously. This process improves rough rolling efficiency, enhances uniformity and thickness stability of thin strips, reduces out-of-tolerance rates, and minimizes rolling-induced cracks.

Abstract: The instant invention provides a deblocking double-layer chromatography and cassette for isolating nucleic acids from liquid biopsy samples such as urine with large sample volumes, small nucleic acid sizes, and low nucleic acid concentrations. Compared with the prior art of Ding et al. (U.S. Pat. No. 9,163,230) which proved the principle of double-layer chromatography comprising a positively charged DEAE membrane and a silica membrane, we further explored and optimized the membrane compositions and solution compositions for plasma and urine samples. More importantly, we set up a “deblocking” mechanism to overcome a “blocking” problem that the membrane is blocked by solid particles in the plasma and urine samples, thus greatly increasing its flowability. In addition, it omits a pre-filtering step, thus particularly suitable for its automation.

Abstract: A method and system for assessing individual and/or overall cooking progress of food items in a food preparation system is disclosed herein. The method for assessing cooking progress of food items relies on reliable annotated data in order to provide real-time feedback and guidance to a user. The methods and systems are specifically trained to optimize the accuracy of determining cooking progress of food items, utilizing a difference feature tensor that compares the cooking progress of a food item with a baseline image of the food item at the start of the cooking process. The noise and averaging effect due to the presence of different food items and/or same types of food items with slight variations in appearances and consistencies are reduced in the cooking progress level determination model, resulting in better accuracy of the cooking progress level assessment.
