Local Field Aperiodic Spectral Power Modulated by Deep Brain Stimulation in Parkinson's Disease
Movement Disorders, EarlyView.Abstract Background Aperiodic spectral broadband power has been described recently as reflecting Parkinson's disease (PD) severity. It has therefore become an increasing focus of research interest in the context of the new adaptive deep brain stimulation (DBS) approach.

From Stability to Chaos: A Complete Classification of the Damped Klein‐Gordon Dynamics
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We investigate the transition between stability and chaos in the damped Klein‐Gordon equation, a fundamental model for wave propagation and energy dissipation. Using semigroup methods and spectral criteria, we derive explicit thresholds that determine when the system exhibits asymptotic stability and when it displays strong chaotic dynamics ...

A Low‐Cost and Compact High‐Frequency Gallium Nitride Gradient Power Amplifier for Low‐Field MRI
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To reduce the upfront cost of small, low‐field MRI systems, while expanding the capabilities of their gradient systems. Methods A gradient power amplifier was designed to leverage the lowering cost of Gallium Nitride (GaN) power transistors and high speed logic, to achieve high efficiency and responsiveness for driving gradient coils ...

Evaluation of broadband MMIC oscillators with external tank
, 2010 This thesis evaluates broadband Voltage Controlled Oscillators, VCO´s, using different VCO topologies and external tanks. The work has been done at Sivers IMA AB within the "INTOSC" project in the framework of the VINNEX Centre "GHZ CENTRE". Different VCO topologies are investigated and their performance is compared and evaluated.

Age‐Dependent Correlation of Pulmonary Function Impairment and Aortic Arch Stiffness in Mice
Pediatric Discovery, EarlyView.This study examined the relationship between aortic arch stiffness and lung function in aging mice. Multiple linear regression modeling showed moderate to strong correlations between the rise in aortic arch stiffness and changes in lung function as the mice progressively aged.
