The Association Between Stress‐Induced Hyperglycemia Ratio and Increased Urinary Albumin Excretion in Patients With Hypertension: A Population‐Based Study

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The stress hyperglycemia ratio (SHR), a novel marker reflecting relative hyperglycemia, has been increasingly recognized for its prognostic value in cardiovascular and metabolic diseases. However, its association with early renal damage in hypertensive patients remains underexplored.

A High-Precision Method for Determining the FBG Peak Wavelength Shift Based on FBG Actual Reflection Spectrum Match [PDF]

, 2011
针对目前光纤布拉格光栅(fbg)解调方案中采用低分辨率CCd测量fbg峰值波长时存在的问题,提出一种采用基于fbg实际反射谱构建基函数匹配CCd测量获得的有限测量点确定fbg峰值波长偏移量的新方法。分别在理论和实测上对这种方法的有效性和可行性进行了研究,证明这种采用fbg实际反射谱函数匹配有限测量数据的方法比采用特定函数拟合测量数据的方法能够更准确地获得fbg峰值波长的偏移量。实现了在CCd采样点数少、光谱分辨率较低的情况下对fbg峰值波长偏移量的高精度确定 ...

Estimated Body Fat Percentage and Triglyceride‐Glucose Index for Identifying MASLD in Lean Asian Adults: A Cross‐Sectional Analysis

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Metabolic dysfunction‐associated steatotic liver disease (MASLD) is increasingly prevalent among lean Asian populations, yet effective strategies for identifying high‐risk individuals remain limited. We investigated the associations of body fat percentage (BF%) and the triglyceride‐glucose (TyG) index with lean MASLD and evaluated their ...

Associations of the Baseline Level and Change in Triglyceride Glucose‐Body Roundness Index With Cardiovascular Diseases: Two Large Prospective Cohorts in Europe and Asia

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The aim of this study was to investigate the association of baseline and changes of TyG‐BRI with incident CVD based on the UK Biobank and China Health and Retirement Longitudinal Study (CHARLS). A total of 418,510 and 7923 individuals from the UK Biobank and CHARLS were included in Analysis 1 (baseline TyG‐BRI with CVD risk).

Estimation of strain of distorted FBG sensor spectra using a fixed FBGfilter circuit and an artificial neural network

, 2013
Fibre Bragg Grating (FBG) sensors are extremely sensitive to changes of strain, and are therefore an extremely useful candidate for Structural Health Monitoring (SHM) systems of composite structures.
