The ability to extract rhythmic structure is important for the development of language, music, and social communication. Although previous studies show infants' brains entrain periodicities auditory rhythms even different metrical interpretations (e.g., groups two vs three beats) ambiguous rhythms, whether premature brain tracks beat meter frequencies has not been explored previously. We used high-resolution electroencephalography while infants ( n = 19, 5 male; mean age, 32 ± 2.59 weeks...

The aim of this study was to develop a novel hybrid genetic algorithm and artificial neural network (GA-ANN) system for predicting the sizes unerupted canines premolars during mixed dentition period. This performed on 106 untreated subjects (52 girls, 54 boys, aged 13-15 years). Data were obtained from dental cast measurements. A GA-ANN developed find best reference teeth most accurate mapping function. Based regression analysis, strongest correlation observed between sum mesiodistal widths...

Rhythm is a fundamental component of the auditory world, present even during prenatal life. While there evidence that some capacities are already before birth, whether and how premature neural networks process rhythm yet not known. We investigated response neonates at 30-34 weeks gestational age to violations from rhythmic regularities in an sequence using high-resolution electroencephalography event-related potentials. Unpredicted elicited fronto-central mismatch response, indicating...

We present a novel method to remove eye blink artifacts from the electroencephalogram (EEG) signals, without using electro-oculogram (EOG) reference electrodes. first model EEG activity by an autoregressive and output-error model, then use Kalman filter estimate true based on integrating two models. The performance of proposed is evaluated different metrics Dataset IIa BCI competition 2008. For RLS algorithm, artifact removal distortion are 7.35 0.79, while for our these 9.53 0.84,...

Memories selectively benefit from sleep. In addition to the importance of consolidation relevant memories, capacity forget unwanted memories is also crucial. We investigated effect suppressing on electroencephalography activity subsequent sleep using a motivated forgetting (MF) paradigm as compared with control non-forgetting task. Subjects were randomly assigned nap or no-nap groups. used modified version think/no-think dominant number no-think words cued be forgotten and included only...

Temporal theta slow-wave activity (TTA-SW) in premature infants is a specific neurobiomarker of the early neurodevelopment perisylvian networks observed as 24 weeks gestational age (wGA). It present at turning point between non-sensory driven spontaneous and cortical network functioning. Despite its clinical importance, underlying mechanisms responsible for this nested functional role have not yet been determined. The coupling neural oscillations different timescales key feature ongoing...

Compliant tubes attain a complex three-dimensional geometry when the external pressure exceeds internal and tube is partially collapsed. A new technique for remote measurement of dynamic surfaces was applied to classical experiments with collapsible tubes. This work presents measurements threedimensional structure as well flow during static loading steady-state fluid flow. Results are shown two same material diameter but different wall thicknesses. The measured laws compare previously...

Abstract-This article focuses on the development of a method to quantitatively assess healing process artificially induced pressure sores using high-frequency (20 MHz) ultrasound images. We in guinea pigs and monitored predefined regions days 3, 7, 14, 21 after sore generation. extracted relevant parameters regarding tissue echographic structure attenuation properties. examined by defining function that used parameters. verified significance features analysis variance multiple comparison...

Pressure ulcers are a common complication among wheelchair-bound population. They resulted from prolonged exposure to high pressure, which restricts blood flow and leads tissue necrosis. In this work, continuous pressure monitoring system is developed for ulcer prevention. The consists of 64 sensors on 40×50 cm2 sheet. Real time data corresponding maps displayed computer simultaneously. Furthermore, posture detection procedure proposed sitting identification. Having information about the...

Rhythm perception and synchronization to periodicity hold fundamental neurodevelopmental importance for language acquisition, musical behavior, social communication. is omnipresent in the fetal auditory world newborns demonstrate sensitivity rhythmic cues. During last trimester of gestation, brain begins respond stimulation code environment. When how during this period do neural capacities rhythm processing develop? We conducted a cross-sectional study 46 neonates (24 male) born between 27...

Alzheimer’s disease (AD) is a neurodegenerative disorder that occurs many years before the first clinical symptoms. Finding more exact, significant, and valuable criteria or indices for diagnosis of mild form very important research purposes. Electroencephalography (EEG) eye tracking biomarkers would provide noninvasive tools early detection AD. Due to advantages EEG tracking, in this study, we employed them simultaneously conduct on For purpose, 19 patients with AD were compared gender-...

Pressure ulcers are tissue damages resulting from blood flow restriction, which occur when a subject's is exposed to high pressure for lengthy period of time. These painful sores common in bedridden and wheelchair-bound patients the elderly. In this work, continuous temperature monitoring system developed ulcer prevention.
