Finger Stiffness [PDF]

open access: yesJournal of Hand and Microsurgery, 2015
Background Finger stiffness varies substantially in patients with hand and upper extremity illness and can be notably more than expected for a given pathophysiology. In prior studies, pain intensity and magnitude of disability consistently correlate with coping strategies such as catastrophic thinking and kinesiophobia, which can be characterized as ...

Stiff knots [PDF]

open access: yesPhysical Review E, 2007
We report on the geometry and mechanics of knotted stiff strings. We discuss both closed and open knots. Our two main results are: (i) Their equilibrium energy as well as the equilibrium tension for open knots depend on the type of knot as the square of the bridge number; (ii) Braid localization is found to be a general feature of stiff strings ...

Joint Stiffness Identification of a Heavy Kuka Robot with a Low-cost Clamped End-effector Procedure [PDF]

open access: yes, 2014
This paper proposes two new methods for the identification of static stiffnesses of multi degrees of freedom heavy industrial robots. They are based on a locked link joint procedure obtained with an end-effector fixed to the environment. The first method

The Stiff Elbow [PDF]

open access: yesHAND, 2009
Elbow motion is essential for upper extremity function to position the hand in space. Unfortunately, the elbow joint is prone to stiffness following a multitude of traumatic and atraumatic etiologies. Elbow stiffness can be diagnosed with a complete history and physical exam, supplemented with appropriate imaging studies. The stiff elbow is challenging

Assessing the Role of Longitudinal Variability of Vertical Track Stiffness in the Long-Term Deterioration [PDF]

open access: yes, 2016
The performance of the railway system in terms of dynamic loading is depending mainly on the track support conditions. Usually, the track stiffness is used as the main parameter to describe the support conditions and is defined as the ratio of the load ...

Establishment and Verification of Nonlinear Bolt Head Connection Stiffness Theoretical Model Based on Levenberg-Marquardt Method

open access: yesIEEE Access, 2020
Although some scholars have established the calculation method of bolt head connection characteristics, the method contains fewer influence factors; the calculation accuracy is not high, and the general applicability is limited.

Laboratory Evaluation of Organic and Chemical Warm Mix Asphalt Technologies for SMA Asphalt

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2012
Warm mix asphalt (WMA) technologies allow significant lowering of the production and paving temperature of the conventional hot mix asphalt (HMA), which promise various benefits, e.g. lowering the greenhouse gas emissions, reduction of energy consumption,

3D Collagen-Nanocellulose Matrices Model the Tumour Microenvironment of Pancreatic Cancer

open access: yesFrontiers in Digital Health, 2021
Three-dimensional (3D) cancer models are invaluable tools designed to study tumour biology and new treatments. Pancreatic ductal adenocarcinoma (PDAC), one of the deadliest types of cancer, has been progressively explored with bioengineered 3D approaches
