Association of glycemic gap with stroke recurrence in patients with ischemic stroke. [PDF]

open access: yesJ Diabetes, 2023
Highlights There was a U‐shaped relationship between glycemic gap and stroke recurrence during a long‐term follow‐up in a Chinese ischemic stroke registry. Clinical physicians should remain vigilant in the fluctuation of glucose level and use individualized glucose control strategies in patients with ischemic stroke.

Modified Delphi study of ultrasound signs associated with placenta accreta spectrum

open access: yesUltrasound in Obstetrics &Gynecology, Volume 61, Issue 4, Page 518-525, April 2023., 2023
ABSTRACT Objective To determine, by expert consensus through a modified Delphi process, the role of standardized and new ultrasound signs in the prenatal evaluation of patients at high risk of placenta accreta spectrum (PAS). Methods A systematic review of articles providing information on ultrasound imaging signs or markers associated with PAS was ...

Transparent machine learning suggests a key driver in the decision to start insulin therapy in individuals with type 2 diabetes 透明机器学习预测决定2型糖尿病患者开始胰岛素治疗的关键驱动因素

open access: yesJournal of Diabetes, Volume 15, Issue 3, Page 224-236, March 2023., 2023
HighlightsML suggests that when the HbA1c gap from a previous visit is >11 mmol/mol (1.0%) there is a greater probability that insulin therapy will be initiated, but when HbA1c gap is <6.6 mmol/mol (0.6%), a timely initiation of insulin therapy is less probable.

A comparison of the stress hyperglycemia ratio, glycemic gap, and glucose to assess the impact of stress‐induced hyperglycemia on ischemic stroke outcome 比较应激性高血糖比率, 血糖间隙和葡萄糖评估应激性高血糖对缺血性卒中预后的影响

open access: yesJournal of Diabetes, Volume 13, Issue 12, Page 1034-1042, December 2021., 2021
Highlights The impact of stress‐induced hyperglycemia on outcome is poorly reflected by absolute glucose levels. The stress hyperglycemia ratio (SHR) biomarker discriminates between interpatient variation in normal premorbid background glycemia related to glycosylated hemoglobin and the acute relative increase in glucose related to physiological stress

Designing 3d Transition‐Metal Doped g‐C3N4 Monolayer for Enhanced Bifunctional Oxygen Evolution/Reduction Reactions Activity: Defect Physics and Constant‐Potential Study

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Graphitic carbon nitride (g‐C3N4) doped with 3d transition metals (3d‐TM@g‐C3N4) has gained attention as a noble metal‐free alternative for oxygen evolution and reduction reactions (OER/ORR). Yet the key mechanisms driving its performance remain debated, especially across different charge states.

Bioinspired 3D‐Printed NiTi Metamaterials With Bivalve‐Like Crossed‐Lamellar Structures

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Metamaterials demonstrate unique mechanical properties and functional performance owing to their distinctive topological spatial structures. In this study, by mimicking the natural Saxidomus purpuratus shell, bioinspired crossed‐lamellar architectures with interlamellar apex angles ranging from 60° to 150° were designed and fabricated in NiTi ...

“PARA QUE TUDO PERMANEÇA COMO É, É NECESSÁRIO QUE TUDO MUDE”: O NIILISMO DE O LEOPARDO DE LAMPEDUSA E O NIILISMO CRISTÃO KIERKEGAARDIANO NO SÉCULO DAS MUDANÇAS

open access: yesPensando - Revista de Filosofia, 2017
Não parece haver, ao menos num primeiro olhar, qualquer ponto de convergência entre a literatura de Lampedusa e a filosofia de Kierkegaard. Contudo, com um pouco mais de investigação, tal percepção revela-se falsa. Ambos os autores se situam no século XIX e, nesse sentido, há forte conexão entre ambos a partir de uma análise histórica, filosófica e ...

Mobilization and Sedimentary Sequestration of Molybdenum in Waters from Watershed to Estuary [PDF]

open access: yes, 2015
钼(Mo)在现代海洋中含量较高(105nM)且相对保守,然而河流中Mo含量变化大,变化范围可以由小于1nM到几百nM,前人工作表明影响流域中Mo的因素是多样性的如富粘土及硫矿的河床、农业及工业、矿山排水等,在这些因素中是如何影响流域Mo的分布尚未清晰。Mo由流域向海洋输送的过程中,在河口区通常认为是保守的,但近些年发现其分布并不完全保守,那么Mo在迁移过程中是否存在水体向沉积物的富集。前人研究沉积物中Mo的富集机制提出多种看法,而未达成一致如:氧化环境下,锰氧化物吸附Mo ...

Comparative Evaluation of Chemical and Physical Expansive Agents in Cemented Paste Backfill: Expansion Behavior, Mechanical Response, and Microstructural Mechanisms

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT This study presents an assessment of four representative expansive additives—calcium sulphoaluminate–calcium oxide, magnesium oxide, sodium lauryl sulfate, and sodium abietate—and their effects on the expansion behavior, mechanical development, and microstructural characteristics of cemented paste backfill (CPB).

Investigation of oxygen precipitates and copper complex in Czochralski silicon [PDF]

open access: yes, 2015
用直拉法生长的单晶硅中,氧是最常见的杂质,硅材料制备过程使用的内吸杂工艺则是以氧沉淀及其诱生缺陷为基础。铜作为最常见的过渡族金属玷污之一,其沉淀及复合体将会较大程度地影响硅材料的性能。因此,研究氧沉淀和铜沉淀及其复合体在直拉硅单晶中的行为,除了具有重要的理论意义外,在实际生产中也可以提高硅器件的性能。本论文利用光学显微镜,傅立叶红外光谱仪及荧光光谱仪对不同热处理方式下硅中氧和铜的行为进行研究,得出的主要结论如下: (1)研究了线性升温(Ramping)的起始温度和升温速率对硅单晶中氧沉淀行为的影响 ...
