Investigating Cerebral Function in Neonates Using Diffuse Optical Tomography
… cerebral activity that gives rise to resting state networks (RSNs) is becoming widely popular. These studies rely on infants to remain asleep to minimise subject motion and optimise data quality. Using DOT combined with electroencephalography (EEG), the effect of sleep state on RSNs was …

The role of melatonin in the effective attainment of electroencephalograms in children in a Sub-Saharan setting
… the few centres with neurophysiology units. Sleep state for EEGs performed on children improves yield and reduces artefact. Melatonin induces “natural sleep” without the risk of airway compromise. This study evaluated the effectiveness of oral melatonin in attainment of useful …

Mother-newborn EEG connectivity during affectionate touch and impact of hypoxic-ischaemic encephalopathy
… touch types, and I show that these responses are sleep state-dependent. Mothers’ brains also showed neonatal state-matching, where mother functional connectivity was adjusted to newborns’ sleep states. Additionally, I present the first evidence of a mother-newborn inter- brain neural network …

Investigating the Impact of Sleep on Early Dynamic Functional Connectivity: A High-Density Diffuse Optical Tomography Study in Term and Preterm Neonates
Poor sleep early in life has been shown to negatively impact neurocognitive functions such as attention, inhibition, and learning (McCann et al., 2018). The impact of sleep on neuronal maturation is especially critical for preterm neonates who experience environmental sleep disruptions early in …

Topics in Power Usage in Network Services
… consumption of servers by moving them into a sleep state and employing a low powered device to act as a proxy in its place. After this we move on to investigate the energy efficiency of virtualisation and compare the energy efficiency of two of the most common means used to do this. Moving on …

Essence : olfactory interfaces for unconscious influence of mood and cognitive performance
… bursts of scent released while the person is asleep or awake. The device can be remotely controlled through a smartphone and can vary the intensity and frequency of the released scent. The system can also potentially be triggered by physiological data such as brain signals, heart rate, or …

The Acquisition and Analysis of Electroencephalogram Data for the Classification of Benign Partial Epilepsy of Childhood with Centrotemporal Spikes
… Second, BECTS patients show differences in sleep state RQA values from centrotemporal and non-centrotemporal regions. We cannot confirm if these differences display epileptiform activity, however, because we do not have controls for sleep studies. With proper development and implementation, …

State of Health Estimation System for Lead-Acid Car Batteries Through Cranking Voltage Monitoring
… during engine cranking and provides a low state of health (SOH) warning of potential battery failure. A reliable SOH estimation should assist users in preventing a sudden battery failure and planning for battery replacement in a timely manner. Most commercial battery health estimation …

Holding and rocking the full-term neonate: the immediate and residual effects on behavioral state and heart rate
… to control and organize l) their behavioral state, 2) their arousal and autonomic functioning, or 3) that there is no clear relationship between immediate responses and long term benefits. Behavioral state and heart rate were collected on 40 infants who were randomly assigned to either a …

Sleep/wakefulness versus urethane anesthesia: analogous arousal states for respiratory control?
… superficially appear like waking (W), light sleep (LS) and slow-wave sleep (SWS) in the unanesthetized animal, referred to as States I, II and DI, respectively. The major question in this thesis was whether the urethane anesthetic states are analogous to the natural states with similar EEG …

Acute Sleep Organization Following Unanesthetized Circumcision of Neonates
Sleep changes in response to environmental pressures and the needs of individuals. The adaptability of sleep is noticeable following largely stressful or adverse events, and is understood to facilitate recovery. Rapid changes in sleep occur in-utero, during the days following birth, and across the …

Impact of a novel relaxation method of touch on neonatal neurobehavioral development among very preterm infants
… growth velocity, and physiologic and behavioral state in hospitalized very preterm infants in a Midwestern academic level IV neonatal intensive care unit (NICU). Results indicate that very preterm infants who received the M Technique over a 5-week period did not differ significantly in …

Mitigating interference coexistence issues in wireless sensor networks

Investigation and Modelling of Fetal Sheep Maturation
… third-trimester with well-defined SWS (slow wave sleep) and REM (rapid eye movement) sleep states. For the late third-trimester, the results of power, correlation time, and SVD (singular value decomposition) entropy analysis demonstrate that the sleep state change is a cortical phase …
