Standing equine cheek tooth extraction: A multivariate analysis of the effect of antibiotics on the risk of post‐operative complications

open access: yesEquine Veterinary Journal, Volume 55, Issue 6, Page 968-978, November 2023., 2023
Abstract Background Commonly, cheek tooth extraction performed in standing horses using perioperative prophylactic antibiotics, results in low post‐operative complication rates. However, no studies have documented the relevance of perioperative antibiotics to the risk of post‐operative complications.

Assessment of subclinical left ventricular systolic dysfunction in patients with type 2 diabetes: Relationship with HbA1c and microvascular complications 2型糖尿病患者亚临床左心室收缩功能障碍的评估:与糖化血红蛋白和微血管并发症的关系

open access: yesJournal of Diabetes, Volume 15, Issue 3, Page 264-274, March 2023., 2023
Highlights In asymptomatic type 2 diabetic patients with preserved left ventricular ejection fraction, a negative correlation of glycated hemoglobin with subclinical left ventricular systolic dysfunction was revealed. Furthermore, glycated hemoglobin may make prognostic significance for the progression of myocardial damage. Abstract Background We aimed

数学知识的反个体主义透视 [PDF]

open access: yes, 2019
数学知识究竟是什么?仅仅诉诸数学家个人的头脑和内在禀赋难以解释其何以能够拥有看似抽象而又客观的数学知识。不管是将数学知识的内涵局限于被证明的命题,还是将数学知识重新诠释为命题间的蕴涵关系、进行数学推理的操作规则和程序以及思考和处理数学问题的技能等,最终均不得不考察数学家与其所处认知环境间的关系才能给出完整解释。可见数学知识无论内容和形式如何,均存在着一个不可或缺的环境维度,认知主体之所以能够拥有数学知识,在构成上依赖于其处于特定的物理环境和社会环境之中,此即"数学知识反个体主义 ...

Minterm tabular method of calculating c-derivative and c-partial derivative in Boolean functions(布尔C-导数及其偏导数的最小项表计算方法)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2015
在逻辑函数布尔c-导数的基础上,引入了布尔c-偏导数的概念.为了简化布尔c-导数及其c-偏导数的计算,提出了基于逻辑函数最小项表的计算方法.该算法用最小项表列出1值最小项的二进制代码,然后对二进制代码中相应位取反变换产生新的最小项,再进行比较并删除新最小项中的重复项来计算c-导数和c-偏导数.实例展示了利用最小项表的计算过程.与代数法和图形法相比,该算法简单有效,当变量数较多时易于计算机编程实现.
