Cortico-muscular coupling and motor performance are modulated by 20 Hz transcranial alternating current stimulation (tACS) in Parkinson’s disease

open access: yesFrontiers in Human Neuroscience, 2014
Parkinson’s disease (PD) is associated with pathologically altered oscillatory activity. While synchronized oscillations between 13 and 30 Hz are increased within a cortico-subcortical network, cortico-muscular coupling is decreased.

Enhanced synchronization in an array of spin torque nano oscillators in the presence of oscillating external magnetic field

open access: yes, 2014
We demonstrate that the synchronization of an array of electrically coupled spin torque nano-oscillators (STNO) modelled by Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation can be enhanced appreciably in the presence of a common external microwave ...

Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

open access: yesAdvanced Materials, EarlyView.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...

Synchronized and desynchronized phases of coupled non-equilibrium exciton-polariton condensates

open access: yes, 2008
We theoretically analyze the synchronized and desynchronized phases of coupled non-equilibrium polariton condensates within mean field theory. An analytical condition for the existence of a synchronized phase is derived for two coupled wells. The case of

Synchronization of spin-transfer oscillators driven by stimulated microwave currents

open access: yes, 2005
We have simulated the non-linear dynamics of networks of spin-transfer oscillators. The oscillators are magnetically uncoupled but electrically connected in series.

Examination of load effects of an alternating current synchronous hydraulic drive

open access: yesMultidiszciplináris Tudományok
Alternating current hydraulic systems can be divided into two large groups based on the electrical analogy: synchronous alternating current hydraulic drives and asynchronous alternating current hydraulic drives. The three main building units of alternating current systems are a hydromotor, a hydrogenerator and a phase space connecting the two main ...
