Enhanced response of the regular networks to local signals in presence of a fast impurity

open access: yes, 2012
We consider an array of inductively coupled Josephson junctions with a fast impurity (a junction with a smaller value of critical current), and study the consequences of imposing a small amplitude periodic signal at some point in the array.

Show, Don't Tell: Learning Reward Machines from Demonstrations for Reinforcement Learning-Based Cardiac Pacemaker Synthesis [PDF]

open access: yesarXiv
An (artificial cardiac) pacemaker is an implantable electronic device that sends electrical impulses to the heart to regulate the heartbeat. As the number of pacemaker users continues to rise, so does the demand for features with additional sensors, adaptability, and improved battery performance.

Exploring the application of ferroelectret nanogenerators in medical engineering

open access: yesFlexMat, EarlyView.
Abstract Flexible devices derived from piezoelectric materials have gained considerable attention due to their exceptional biocompatibility. Among these, ferroelectret nanogenerators (FENG) is a novel type of flexible piezoelectric device that integrates self‐powering, actuation, and sensing capabilities.

Caged calcium in Aplysia pacemaker neurons. Characterization of calcium-activated potassium and nonspecific cation currents. [PDF]

open access: yes, 1989
We have studied calcium-activated potassium current, IK(Ca), and calcium-activated nonspecific cation current, INS(Ca), in Aplysia bursting pacemaker neurons, using photolysis of a calcium chelator (nitr-5 or nitr-7) to release caged calcium ...

Research progress on the depth of anesthesia monitoring based on the electroencephalogram

open access: yesIbrain, Volume 11, Issue 1, Page 32-43, Spring 2025.
Electroencephalogram (EEG) can noninvasive, continuous, and real‐time monitor the state of brain electrical activity, and the monitoring of EEG can reflect changes in the depth of anesthesia (DOA). The development of artificial intelligence can enable anesthesiologists to extract, analyze, and quantify DOA from complex EEG data.

The Vestibular Implant Input Interacts with Residual Natural Function

open access: yesFrontiers in Neurology, 2017
ObjectivePatients with bilateral vestibulopathy (BV) can still have residual “natural” function. This might interact with “artificial” vestibular implant input (VI-input). When fluctuating, it could lead to vertigo attacks.

Kuramoto Oscillators on Chains, Rings and Cayley-trees [PDF]

open access: yesarXiv, 2005
We study systems of Kuramoto oscillators, driven by one pacemaker, on $d$-dimensional regular topologies like linear chains, rings, hypercubic lattices and Cayley-trees. For the special cases of next-neighbor and infinite-range interactions, we derive the analytical expressions for the common frequency in the case of phase-locked motion and for the ...

Advancements in Magnesium Applications, Biocompatible Implants to Nanoparticles in Medicine and Biomedical Innovations

open access: yesMetalMat, EarlyView.
Magnesium (Mg) and its alloys are identified as prospective materials for orthopedic and cardiovascular applications because of their bio‐corrosiveness and ability to stimulate tissue reparative processes. Although compared with traditional metals, Mg is biocompatible; however, it has various problems that stem from its biodegradation nature, for ...

Procedimiento de Enfermería en la implantación de marcapasos transvenoso temporal.

open access: yesNURE Investigación, 2013
La implantación de marcapasos transvenoso temporal (MPTT) es una técnica que consiste en estimular de forma artificial el corazón cuando los marcapasos naturales no pueden mantener el ritmo y la frecuencia adecuados.
