城市人口吸引力的测度与演变分析是研究低生育背景下城市人口可持续发展的重要方法。根据外来人口竞争力和稳定性微观特质提出就业迁移假说,据此选取16个指标构建城市人口吸引力评价体系,运用主成分-灰色关联度综合分析法对2015—2022年环太湖五市吸引外来人口定居的能力进行测度,分析环太湖五市城市人口吸引力时序演变及构成规律。研究认为:2015—2022年环太湖五市城市人口吸引力总体保持上升趋势,收入水平和生活质量是构成环太湖五市城市人口吸引力的首要因素;嘉兴和湖州的城市人口吸引力整体强于苏州、无锡、常州,原因在于就业机会多,消费制约弱,对弱竞争力外来人口更具吸引力;环太湖五市城市人口吸引力各具特点,通过比较分析提出人口引进政策优化建议。

Background and Aim: Ecthyma gangrenosum (EG) is a rare necrotic skin infection caused by Pseudomonas aeruginosa occurring on healthy skin mainly, but not exclusively, in immunocompromised patients. We report the case of EG of unusual presentation in a 12-month-old infant. Case Presentation: This was a 12-month-old male infant who was referred from a peripheral structure for the treatment of facial swelling associated with fever. In his antenatal and intra nasal history, there was a notion of hospitalization for 15 days for early neonatal infection and a delay in psychomotor development. The admission examination showed the fair general condition, hyperthermia at 39°C, tachycardia at 136 beats/minute, and polypnea at 48 cycles/minute. The weight-for-height index with a z-score of 3DS was also found. The dermatological examination at the entrance found an extensive brownish inflammatory tense infiltrated plaque taking the mandibular, submental, retro-auricular occipital regions rapidly evolving towards necrosis, a significant swelling predominant on the upper right eyelid preventing the opening of the associated eyes to mouth ulceration. Biological abnormalities were predominantly neutrophilic leukocytosis, elevated CRP, and elevated muscle enzymes. Microbiological examination of skin samples had isolated Pseudomonas aeruginosa. He had received antibiotic therapy, and a necrosectomy under general anesthesia. The evolution was favorable and he was discharged from the hospital on D26 of hospitalization. Conclusion: This observation is rare due to its location, its early onset, and non-neutropenic background.

Shor算法能够借助量子计算机以多项式级别复杂度解决大整数因式分解问题,从而破解一系列安全性基于大整数因式分解的加密算法,例如Rivest-Shamir-Adleman加密算法、Diffie-Hellman密钥交换协议等.由于量子测量结果是概率性的,在运行量子线路时很容易受到噪声的干扰,这将导致无法测量得到预期结果.本文分别研究了不同通道的噪声对Shor算法的影响,分别是去极化通道、状态制备与测量通道以及热退相干通道.本文模拟在噪声环境中运行Shor算法并且给出了数值结果.数值结果表明Shor算法成功分解整数的概率易受到噪声影响,其中去极化通道中的噪声能够以指数形式影响Shor算法成功分解整数的概率,其次是热退相干通道噪声,最后是状态制备与测量通道噪声,能够线性影响到Shor算法成功分解的概率.本文能够为后续纠错、改进Shor算法以及确定工程实现Shor算法所需要的保真度等提供建设性意见.

缪希雍为晚明著名医家,不仅医术高明,且活跃于晚明士大夫及佛教信仰圈之中,一直为中医史及江南社会史研究所关注。但作为一位杏林名家与党争清流,缪氏的生卒年,在学界尚无令人准确的说法;尤其出生年,长期流传多个不同版本,且彼此相去甚远。通过研究《径山藏》所录缪氏亲笔牌记,纠前人关于朱国祯所作祝寿文之考证错误,辅以相关文献,考得缪氏当生于嘉靖三十二年(1553),卒于天启五年(1625)六月至天启六年(1626)三月之间。

The study of the morphology of White Blood Cells (WBCs) further contributes to the clinical diagnosis of blood diseases. In this research paper, we come up with an image segmentation enhancement by combining Fourier Fast Transform on smear blood capture and classical thresholding. The Fast Fourier Transform (FFT) is a very powerful tool in image processing and it was used to segment and extract the WBCs. Our image processing method uses a Fast Fourier Transform combined with filtering and an Inverse Fast Fourier Transform for the extraction and visualization of the high frequency region of the image. In order to remove residual Red Blood Cells acting as noise in the expected result, a final thresholding step is added at the end of the processing. The results presented in this article report the tests performed using our mathematical implementation. Moreover, we were able to detect and differentiate the sub-families of WBCs.
