New generating function formulae of even- and odd-Hermite polynomials obtained and applied in the context of quantum optics

By combining the operator Hermite polynomial method and the technique of integration within an ordered product of operators, for the first time we derive the generating function of even- and odd-Hermite polynomials which will be useful in constructing new optical field states. We then show that the squeezed state and photon-added squeezed state can be expressed by even- and odd-Hermite polynomials.

超声S-Detect技术联合乳腺简化MRI在乳腺体检中的应用价值研究

目的运用超声S-Detect技术联合乳腺简化MRI对乳腺肿瘤患者进行检查,探讨该联合检查技术在乳腺体检工作中的应用价值。方法选择2020年1月—2021年12月在唐山市妇幼保健院进行乳腺超声和MRI检查,并进行穿刺或手术获得病理结果的120个肿瘤病灶。以乳腺肿瘤病理结果为金标准,评估超声S-Detect技术、乳腺简化MRI及二者联合诊断的诊断效能。结果S-Detect、简化MRI及两者联合诊断的灵敏度分别为80.9%、88.3%、94.7%,特异度分别为73.1%、84.6%、88.5%,准确率分别为79.2%、87.5%、93.3%,与病理一致性检验Kappa值分别为0.47、0.66、0.81,AUC分别为0.77、0.86、0.91。结论超声S-Detect与乳腺简化MRI技术联合对乳腺肿瘤检查的灵敏度、特异度、准确率以及与病理一致性比单独使用SDetect技术或者简化MRI高,能够更有效检出乳腺肿瘤并区分良恶性,为乳腺肿瘤的发现起到了积极作用,并为临床制定治疗方案提供了帮助。
