Error Analysis of PDR System Using Dual Foot-mounted IMU [PDF]

E3S Web of Conferences, 2019
In this paper, we analyze the position errors of the pedestrian dead reckoning (PDR) system using foot-mounted IMU attached to each foot, and implement PDR system using dual foot-mounted IMU to reduce the analyzed error. The PDR system using foot-mounted

Glycemic Control, Animal Protein Intake, and the Risk of Diabetic Retinopathy Progression Among Patients With Type 2 Diabetes

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Effective glycemic control and food consumption play crucial roles in modulating diabetic retinopathy (DR) progression. This observational longitudinal study explored the hemoglobin A1c (HbA1c) and dietary patterns and their associations with the risk and progression of DR among 369 individuals with type 2 diabetes.

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries

Pest Management Science, Volume 81, Issue 4, Page 1740-1751, April 2025.
Electrolyzed water treatments could have promising applications in the grapevine nursery process to prevent or reduce infections caused by fungal trunk pathogens on grapevine propagation material. Abstract BACKGROUND Grapevine producers demand solutions to control fungal trunk pathogens (FTPs) in nurseries.

If Not Now, When? Thinking about Childbearing in Ukrainian Cities during Russia's Full‐Scale Invasion

Population and Development Review, EarlyView.
Abstract Prior literature on fertility during war examines high‐fertility settings using quantitative data on births collected mainly after fighting ends. In contrast, we analyze cognitive processes related to childbearing during wartime in Ukraine, where a full‐scale war erupted in the context of long‐standing low fertility.
