12月18日晚，古鳌科技（300551）发布公告，公司近日收到公司前控股股东、实际控制人陈崇军家属送 达的山东省青岛市中级人民法院《刑事判决书》。陈崇军犯操纵证券市场罪，判处有期徒刑六年，并处 罚金人民币四百万元。 公司分别于2024年4月25日、2024年5月28日披露了《关于公司实际控制人被刑事拘留的公告》《关于公 司实际控制人被批准逮捕的公告》，陈崇军因涉嫌操纵证券市场罪于2024年4月18日被刑事拘留，同年5 月24日被逮捕。 对于公司的影响，古鳌科技表示，陈崇军为公司前任控股股东、前任实际控制人，上述判决为股东个人 行为，不会对公司生产经营产生重大不利影响。目前，公司经营情况正常。 公开履历显示，陈崇军生于1968年，为古鳌科技创始人，此前曾在相当长的一段时间内身兼公司董事 长、总经理两大要职。2021年10月，陈崇军因个人原因辞去公司总经理职务；2023年5月，古鳌科技董 事会换届，陈崇军不再担任董事，亦不再任董事长职务。此后未在公司担任具体职务。记者注意到，目 前在古鳌科技官网还能看到陈崇军本人的照片。 就在几天前，陈崇军刚刚让出古鳌科技实控人的位置。公告显示，12月12日，陈崇军与徐迎辉签订《 ...

Core Viewpoint - The introduction of new pear varieties, particularly "Ningli Early Dew," showcases advancements in breeding techniques aimed at enhancing taste, appearance, and cultivation efficiency in the pear industry [1][2]. Group 1: New Pear Varieties - "Ningli Early Dew" is a new pear variety that matures in late June, which is half a month earlier than traditional early-ripening pears, with a growth period of approximately 90 days from flowering to maturity [1][2]. - The variety has a fruit weight of 280-320 grams and features a small core, providing a sweet and juicy taste experience [1]. - Other new varieties presented include "Ning Early Gold," "Ning Late Green," and a red-skinned pear series, all developed by the Nanjing Agricultural University pear innovation team [1][2]. Group 2: Breeding Techniques - The breeding process for new pear varieties traditionally takes 12 to 15 years; however, the research team has implemented image recognition and machine learning technologies to accelerate this process [2]. - The development of the "Cloud Shang Hou Ji" breeding information platform has standardized data collection and improved the efficiency of new pear variety creation [2]. - The combination of hybrid breeding, bud mutation, and molecular marker selection has significantly enhanced the speed and effectiveness of new variety development [2]. Group 3: Market Impact - The newly introduced varieties cover a range of maturity periods from extremely early to mid-late, ensuring a continuous supply of fresh pears in Jiangsu from late June to early September [4].

Group 1 - The core viewpoint of the articles highlights the significant advancement in quantum artificial intelligence (AI) through the application of boson sampling for image recognition, marking a crucial step towards practical quantum AI applications in real-world scenarios [1][2]. - The research team from Okinawa Institute of Science and Technology successfully utilized a quantum AI system for image classification using only three photons and a linear optical network, demonstrating the potential for low-energy, hybrid quantum methods [1][2]. - The developed quantum AI architecture compresses grayscale image data into single-photon quantum states, which are then processed through a complex optical network to create high-dimensional patterns, achieving superior accuracy compared to traditional machine learning methods [2]. Group 2 - The principle of boson sampling is explained through an analogy of a "marble board" game, illustrating how photons, unlike marbles, exhibit wave-like behavior that leads to complex interference patterns that are difficult to predict even for supercomputers [2]. - The experimental results indicate that the quantum AI system outperformed traditional machine learning approaches across all tested image datasets, showcasing its effectiveness in image recognition tasks [2].
