The connection between the olfactory system and the hippocampus, where degeneration due to the disease occurs, is being explored. The aim is to be able to provide a biomarker for diagnosis and a therapy to train the …

Enhanced Gamma Band Mutual Information Is Associated With Impaired Consciousness During Temporal Lobe Seizures, Puneet Dheer, Sandipan Pati, Kalyan Kumar Chowdhury, Kaushik Kumar Majumdar

Journal Articles

Background: Epileptic seizures are characterized by aberrant synchronization. We hypothesized that higher synchronization across the seizure onset zone (SOZ) channels during a temporal lobe seizure contributes to impaired consciousness. New method: All symmetric bivariate synchronization measures were extended to multivariate measure by a principal component analysis (PCA) based technique. A novel nonparametric method has been proposed to test the statistical significance between increased synchronization across the seizure onset zone (SOZ) channels and reduced consciousness. Results: Increased synchronization in the gamma band towards seizure termination significantly contributes to impaired consciousness (p < 0.1). Synchronization reaches its peak in the extratemporal region (frontal lobe) ahead of the temporal region (p < 0.05). Synchronization is prominent in beta and gamma bands by most methods and it is more in the second half of seizure duration than in the first (p < 0.05). Conclusions: Mutual information is the only synchronization measure out of the six that we studied, whose increase can be associated with the loss of consciousness in a statistically significant way.

Drift Capacity Of Structural Walls With Lap Splices, William Pollalis, Santiago Pujol

Bowen Laboratory Research Reports

Twelve large-scale reinforced concrete specimens with lap splices in the longitudinal reinforcement were tested at Purdue University’s Bowen Laboratory to produce data to evaluate the deformability of structural walls with lap splices at their base. Previous work on lap splices has focused mainly on splice strength. But in consideration of demands requiring structural toughness (e.g. blast, earthquake, differential settlement), deformability is arguably more important than strength.
To obtain data on splice deformability and to study the response of lap splices in conditions more representative of those occurring in structural walls, eight specimens were tested under four-point bending and four additional …

Promoting The Sustainable Utilization Of Groundwater Resources In Ethiopia Using The Integrated Groundwater Footprint Index, Xinyu Lin

Honors Scholar Theses

The country of Ethiopia is highly vulnerable to human-caused climate change and is already suffering from the effects. The predominately rural population relies heavily on small-scale agriculture, with 78% of households having at least one member engaged in the field, yet staple crops are highly susceptible to droughts and other weather shocks. Total and agricultural GDP growth in the country have been strongly linked to inter-annual rainfall variability, of which Ethiopia has among the highest in sub-Saharan Africa. A decrease in rainfall since the 1970s has been one of the primary causes of low crop yields, and stresses the immediate …

Targeted Presentation Skill Trainings To Nurture Construction Management Students At Florida International University, Gabriella D. Santi Kasabdji

FIU Electronic Theses and Dissertations

In today’s fast-paced work environment, competent construction managers (CM) are vital for project success. However, to be competent, these professionals require the mastery of not only technical skills but also soft skills that enable them to achieve their full potential. Regardless, many CM prize technical abilities over the day-to-day writing, speaking, and overall soft skills, assuming these are not as important to the knowledge of complex concepts. Industry leaders confirm this, as evidence states graduate construction managers lack the basic communication skills to “hit the ground running”. That said, academic programs should seek to adapt and nurture these vital skill …
