Growing synfire chains with triphasic spike-time-dependent plasticity
… spike-timing-dependent plasticity (STDP) rule, triphasic STDP, plus activity-dependent excitability. This STDP rule, which has not been previously used in computational studies, is shown to successfully develop a synfire chain in a network of binary neurons. The width and length of the final …

Towards a triphasic Theory of Porous Media-based model for chloride-induced corrosion in reinforced concrete
This thesis is concerned with the initial development of a multiphase material model using the Theory of Porous Media (TPM) for the penetration of intermediary rust product into reinforced concrete subjected to chloride-induced corrosion. Research has shown that although the majority of …

Coordination Cages for the Separation and Transportation of Molecular Cargo
… designed. Building upon these observations, a triphasic sorting system is presented such that each of three different host-guest complexes are soluble in only one of three immiscible liquid phases. In contrast to the static triphasic system described in the second chapter, the third chapter …

A tri-phasic continuum model for the numerical analysis of biological tissue proliferation using the Theory of Porous Media. Application to cardiac remodelling in rheumatic heart disease
… and interstitial fluid (liquid phase) [21], to a triphasic model with inclusion of a third nutrient phase. This inclusion is motivated by the reason to constrain the volume of the liquid phase within the system in response to the description of growth, which is modelled through a mass exchange …

Functional and Categorical Analysis of Waveshapes Recorded on Microelectrode Arrays
… activity display a great variety of shapes with triphasic signals predominating. I characterized extracellular recordings from over 600 neuronal signals. I have preformed a categorical study by dividing wave shapes into two major classes: (type 1) signals in which the large positive peak follows …

Effects of the menstrual cycle and oral contraceptives on athletic performance
… cycle and the administration of a low-dose triphasic oral contraceptive agent (OCA)on selected measures of athletic performance in a group of elite female athletes. Nineteen eumenorrheic women were studied during the midfollicular (day 5.7 ± 0.5; mean + SE) and midluteal (day 23.3 ± 0.9) …

Gender role conflict and alcohol metacognitions : implications for the Marlatt Model of Relapse Prevention
… The present study argues that development of a triphasic metacognitive formulation for problematic drinking (Spada, Caselli, & Wells, 2012) represents the single most important advance in alcohol treatment since the advent of the Marlatt model. The formulation postulates that a reduction in …

Development and Verification of Poroelastic Barrier Model With Active Transport: Application in Human Epidermis
… stage we assume that the epidermis consists of a triphasic medium in which live cells act as sources and sinks for water and solutes. The transepidermal transport is numerically solved after applying the method of volume averaging. The second stage involves the use of a model passive (acellular) …

CNS delivery of antisense oligodeoxynucleotides using biodegradable microspheres
… microspheres over 56 days that were triphasic were observed with high molecular weight polymers. Antisense oligodeoxynucleotides loaded into microspheres (1-10μm) had a five-fold increase in cellular association with glial and neuronal cells compared to the naked molecule, which was …

A three constituent mixture theory model of cutaneous and subcutaneous tissue in the context of neonatal pressure ulcer etiology and prevention
… under time-varying loading. In this study, a triphasic mixture theory model with constituents of extracellular matrix, interstitial fluid, and blood was calibrated and validated and used to investigate stress and fluid velocity under quasi-static and time-varying loading conditions, …

Advanced Engineering of Contact Lens Coatings using Electrohydrodynamic Atomization
… profiles; ranging from biphasic profiles to triphasic profiles. Ex vivo analysis and biological compatibility testing also presented promising results. The use of EHDA has not yet been explored in depth within the ocular research remit. It has shown great potential in the work presented here; …

Proximal Influence vs. Institutional Power: An Empirical Study of Podcasts, Trust and Public Opinion
… the fragmented trust in mass media. Employing a triphasic mixed-methods design, this study combines survey, interview, and case profile data analysed through thematic analysis, content analysis, exploratory factor analysis and regression analysis to identify predictors and effects of podcast …

The versatility and utilization of phosphorus based compounds in classic carbon-carbon bond forming and esterification reactions
… and hexane to the reaction products results in a triphasic system, from which the catalyst was then recycled by removing the top (hexanes) and bottom (aqueous) layers and adding the reagents to the ionic liquid which was heated again at 50°C; resulting in complete turnover of iodobenzene. …

Experimental and finite element analysis of mechano-electrochemical effects in intervertebral disc biomechanics
… Differences were found between biphasic and triphasic models which resulted in varying agreement with experimental data thus the correct selection of numerical framework was found to be crucial when investigating disc mechanics. The data presented in this thesis are important for informing …

Biodegradable polymers for the sustained release of antisense nucleic acids
… over the release period, resulting in a triphasic release profile. An increase in release was observed when sphere size and polymer molecular weight were decreased. The polymer entrapped phosphodiester oligodeoxynucleotides and ribozymes had enhanced stability compared to free …

Protein-protein interactions and mechanistic insights for CYP2J2 and CYP5A1
… cytochrome P450 reductase (CPR). Here the triphasic kinetics of the potentially rate-limiting first electron transfer from CPR to CYP2J2 are reported. These rates are similar to previously reported rates of other CYPs and show differences with CYP2J2 in the presence of the substrates …
