Association between triglyceride-glucose index and risk of arterial stiffness: a cohort study
Cardiovascular Diabetology, 2021 Background Triglyceride–glucose (TyG) index, a simple surrogate marker of insulin resistance, has been reported to be associated with arterial stiffness. However, previous studies were limited by the cross-sectional design.

A stiffness-based quality measure for compliant grasps and fixtures [PDF]
, 2000 This paper presents a systematic approach to quantifying the effectiveness of compliant grasps and fixtures of an object. The approach is physically motivated and applies to the grasping of two- and three-dimensional objects by any number of fingers. The

Plate-nanolattices at the theoretical limit of stiffness and strength
Nature Communications, 2020 Though beam-based lattices have dominated mechanical metamaterials for the past two decades, low structural efficiency limits their performance to fractions of the Hashin-Shtrikman and Suquet upper bounds, i.e.

Estimation of the normal contact stiffness for frictional interface in sticking and sliding conditions [PDF]
, 2019 Modeling of frictional contact systems with high accuracy needs the knowledge of several contact parameters, which are mainly related to the local phenomena at the contact interfaces and affect the complex dynamics of mechanical systems in a prominent ...

Morphological and functional changes in the vertebral column with increasing aquatic adaptation in crocodylomorphs [PDF]
Royal Society Open Science, 2015 The lineage leading to modern Crocodylia has undergone dramatic evolutionary changes in morphology, ecology and locomotion over the past 200+ Myr. These functional innovations may be explained in part by morphological changes in the axial skeleton, which

Modeling and design of energy efficient variable stiffness actuators [PDF]
, 2010 In this paper, we provide a port-based mathematical framework for analyzing and modeling variable stiffness actuators. The framework provides important insights in the energy requirements and, therefore, it is an important tool for the design of energy ...

Deformation and stiffness of spur gear teeth and their influence on gear noise [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2015 Gear teeth are deformed due to the load. The deformation of gear teeth is causing some negative as well as positive effects. A tooth has a complex shape and due to the complex shape of the teeth, a theoretical determination of the deformation is ...

Spin wave stiffness and exchange stiffness of doped permalloy via ab-initio calculation
, 2019 The way doping affects the spin wave stiffness and the exchange stiffness of permalloy (Py) is investigated via ab-initio calculations, using the Korringa-Kohn-Rostoker (KKR) Green function formalism.
