Should We Forget the Jerk in Trajectory Generation?

Vibration
This article explores whether jerk, the derivative of acceleration, should be limited in trajectory planning for position-controlled mechanical systems or in the controller.

Novel MYL1 Intron Variant With Expanded Phenotype

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Congenital myopathy‐14 (CMYO14) is an ultrarare autosomal recessive disorder caused by biallelic variants in MYL1, with only four patients reported to date. We describe what is likely the fifth reported patient, a neonate with severe hypotonia, respiratory insufficiency, and skeletal anomalies showing distinct histological changes of skeletal ...

Jerky chiral active particles

New Journal of Physics
We introduce jerky chiral active Brownian particles (ABP), a generalization of conventional chiral ABPs subjected to jerk, the time derivative of acceleration, and analytically derive their mean displacement and mean squared displacement.

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.

A new chaotic jerk system with a sinusoidal nonlinearity, its bifurcation analysis, multistability, circuit design and complete synchronization design via backstepping control [PDF]

Archives of Control Sciences
In this research work, we investigate a new three-dimensional jerk system with three parameters in which one of the nonlinear terms is a sinusoidal nonlinearity.

Research progress on biomarkers of traumatic brain injury

Animal Models and Experimental Medicine, EarlyView.
Traumatic brain injury: From primary insult to secondary neuroinflammation and degeneration. Abstract Traumatic brain injury (TBI) is a common disorder of the nervous system and has become a leading cause of death and disability worldwide, imposing a substantial burden on patients and their social circles. Its main symptoms include dyskinesia, language

Study on jerky dynamic characteristics of energy absorbing materials based on impact test

Meitan xuebao
In order to study the energy absorption effect and dynamic response characteristics of silicon-based strain rate-sensitive energy-absorbing materials under impact load, impact tests of energy-absorbing materials were conducted on the 6000 kN hydraulic ...

Observational Constraints on the Generalized Chaplygin Gas

, 2009
In this paper we study a quintessence cosmological model in which the dark energy component is considered to be the Generalized Chaplygin Gas and the curvature of the three-geometry is taken into account.

Effects of intermittent exposure to hypobaria and cold on the microarchitecture and morphofunctional profile of rat gastrocnemius muscle

The Anatomical Record, EarlyView.
Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...
