Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Three-phase wound-rotor synchronous generators are the main source of electrical power worldwide. They require a prime mover and an exciter in order to generate power. The prime mover can be a turbine spun by fluid (gas or liquid), thus the sources of the fluid can be water running off a dam through a long nozzle, steam from water evaporated using burned coal, etc. Most power plants including coal,...

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. Three-phase wound-rotor synchronous motors are less popular than permanent magnet rotor synchronous motors due to the brushes required for the rotor field. Synchronous generators are much more common and available in most existing power plants, as they have excellent frequency and voltage regulation. Synchronous motors have the advantage of almost 0% speed regulation due to the fact that the rotor...

This paper describes using a breath-synchronized olfactometer to trigger single- and dual-coil transcranial magnetic stimulation (TMS) during odorant presentation synchronized to human nasal breathing. This combination allows us to objectively investigate how pleasant and unpleasant odors impact corticospinal excitability and brain-effective connectivity in a given individual.

This video describes how to perform CO2 measurement in intubated as well as spontaneously breathing patients. The main clinical indications refer to emergency situations: (1) verifying adequate positioning of an endotracheal tube; (2) achieving normocapnia in trauma patients; (3) monitoring ventilation in the case of procedural sedation.
FAQs
Nasal airflow can provide a rhythmic timing signal through inhalation and exhalation, while respiratory circuits generate related patterned activity. These signals may align neural oscillations across regions involved in olfaction, memory, attention, and emotion. Studying this alignment helps neuroscientists examine how respiratory timing contributes to coordination among distributed brain systems.
Inhalation is not merely a phase of the breathing cycle; its timing may influence when neural information is processed. Because airflow and respiratory activity produce patterned signals, the inhalation phase can be compared with changes in neural rhythms. This approach helps researchers investigate whether respiration-related timing affects sensory, cognitive, or emotional processing.
Comparing nasal with mouth breathing provides a way to test whether the route of airflow changes respiration-related neural activity. Nasal breathing supplies airflow signals associated with the nasal pathway, whereas mouth breathing offers a contrasting respiratory condition. Such comparisons can clarify how breathing route relates to synchronization involving olfaction, memory, attention, and emotion.
Researchers examine the temporal relationship between breathing-related signals and rhythmic neural activity. They can focus on how inhalation and exhalation correspond to activity across brain regions, then compare conditions such as nasal and mouth breathing. The resulting patterns help characterize brain-body communication and identify respiration-related changes in neural synchronization.
Attention and memory are central applications because respiration-related neural timing may influence how information is processed in systems supporting these functions. Olfactory and emotional processing are also relevant because the linked brain regions participate in the broader coupling between breathing and neural activity. Research may additionally examine how these relationships change during sleep.
Altered breathing offers an important context for investigating whether changes in respiratory patterns correspond to changes in neural synchronization. In neuroscience, this connection may help researchers characterize brain-body communication in disorders involving breathing or altered neural coordination. The goal is to identify respiration-related differences without assuming that every breathing change produces the same neural outcome.
