Dynamic Control Of The Cardiac Calcium Pump, Sean Robert Cleary Jan 2023

Dynamic Control Of The Cardiac Calcium Pump, Sean Robert Cleary

Dissertations

The sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) sequesters Ca2+ into the endoplasmic reticulum of cells to establish a reservoir for Ca2+ signaling. In the heart, the activity of this transporter is tightly controlled via direct interactions with two competing regulatory micropeptides: phospholamban (PLB) and dwarf open reading frame (DWORF). PLB inhibits SERCA, while DWORF activates SERCA. These competing interactions determine cardiac performance by modulating the Ca2+ signals that drive the contraction/relaxation cycle. Previous studies indicated these SERCA-micropeptide interactions are Ca2+-sensitive; SERCA binds PLB more avidly at low cytoplasmic [Ca2+] but binds DWORF better when [Ca2+] is high. Here, FRET-microscopy demonstrated that this …

Design And Synthesis Of Novel Antibiotics And Anticancer Agents Targeting Pharmaceutically Relevant Enzymes, Sebastian Flieger

Dissertations

Boron neutron capture therapy (BNCT) is a binary radiotherapeutic modality for cancer treatment, in which delivery agents containing 10B atoms are transported into tumor cells and then irradiated with low-energy thermal neutrons. Matrix metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases that are involved in the remodeling and degradation of all components of the extracellular matrix (ECM). Overexpressed levels of MMP activity have been implicated in several disease states including tumor growth and metastasis. We have appended a borane-rich carborane cluster onto MMP-targeting pharmacophores to enable delivery of 10B atoms to a tumor. Herein, we describe the molecular docking experiments …

A Practice-Led Inquiry Into Collaboration With Landscape Within The Expanded Field Of Photography, Laurie Reynolds Jan 2023

A Practice-Led Inquiry Into Collaboration With Landscape Within The Expanded Field Of Photography, Laurie Reynolds

School of Art, Design and Architecture Theses

It is the intent, by working within the expanded field of photography, sculpture, video archiving and writing practice, to create a new theoretical model of landscape’s agency as co-author and collaborator. The inquiry is approached through a Deleuzian sense of crystallization; a process of forming concepts through a series of encounters with post-industrial landscapes. Through practice, these encounters are an attempt to understand the nature of collaborating with a non-human agency; explored not through historical, material, or evolutionary origins, but rather, through the conditions that afford the emergence of a collaborative practice. These encounters are transcribed and presented through the …

Mathematical Analysis Of Convolutional Neural Networks, Daniel Mccarter Jan 2023

Mathematical Analysis Of Convolutional Neural Networks, Daniel Mccarter

Dissertations and Theses

In this thesis, the main topic is convolution as a mathematical operation and Convolutional Neural Networks (CNN’s). While convolution is classically defined as a function, it can also be defined as an operator from Lp(R) to itself for 1 ≤ p ≤ 2 where Tw(f ) = f ∗ w given some w ∈ L1(R). CNN’s use convolution in its convolutional layers. Defining a neural network to be the composition of layer maps, we find that the neural network is, by necessity, Lipschitz. While CNN’s can be very powerful for image classification, slight changes to an image can completely fool …

Functional Comparison Of Full-Length Palladin To Isolated Actin Binding Domain, Sharifah Albraiki, Oluwatosin Ajiboye, Rachel Sargent, Moriah R. Beck

Research, Publications & Creative Work

Palladin is an actin binding protein that is specifically upregulated in metastatic cancer cells but also colocalizes with actin stress fibers in normal cells and is critical for embryonic development as well as wound healing. Of nine isoforms present in humans, only the 90 kDa isoform of palladin, comprising three immunoglobulin (Ig) domains and one proline-rich region, is ubiquitously expressed. Previous work has established that the Ig3 domain of palladin is the minimal binding site for F-actin. In this work, we compare functions of the 90 kDa isoform of palladin to the isolated actin binding domain. To understand the mechanism …

Minimax Estimation For Personalized Federated Learning: An Alternative Between Fedavg And Local Training?, Shuxiao Chen, Qinqing Zheng, Qi Long, Weijie J Su Jan 2023

Minimax Estimation For Personalized Federated Learning: An Alternative Between Fedavg And Local Training?, Shuxiao Chen, Qinqing Zheng, Qi Long, Weijie J Su

Faculty, Staff and Student Publications

A widely recognized difficulty in federated learning arises from the statistical heterogeneity among clients: local datasets often originate from distinct yet not entirely unrelated probability distributions, and personalization is, therefore, necessary to achieve optimal results from each individual's perspective. In this paper, we show how the excess risks of personalized federated learning using a smooth, strongly convex loss depend on data heterogeneity from a minimax point of view, with a focus on the FedAvg algorithm (McMahan et al., 2017) and pure local training (i.e., clients solve empirical risk minimization problems on their local datasets without any communication). Our main result …

The Criticality Of Teacher Educator Wellbeing: Reflecting Through Arts-Based Methods, Kristina Turner, Georgina M. Barton Dr, Susanne Garvis, Ellen Larsen

Australian Journal of Teacher Education

Teacher educators face many challenges related to workload and government-mandated reforms in Initial Teacher Education programs. Evidence suggests that COVID-19 has exacerbated these challenges as universities must become more cost-effective and improve research outcomes and impact, often resulting in heavier workloads. While these challenges may be faced in other disciplines, teacher educator wellbeing, stress and burnout is an under-researched field, and little is known about if and how teacher educators maintain their wellbeing during times of uncertainty. This collaborative autoethnographic study applied an arts-based research method to explore the wellbeing challenges faced by four Australian teacher educators through the lens …

Teachers' Views On The Nature Of Science: An Epistemological Analysis, Rafael Amador Rodríguez, Natalia Ospina Quintero, Agustín Adúriz Bravo

Australian Journal of Teacher Education

This article presents results of research analysing the views on the nature of science (NOS) among primary and secondary teachers working in state schools in two different cities in Colombia. Previous studies have reported that science teachers maintain ‘eclectic’ epistemological perspectives on science; in this article, we test if such hypothesis holds when teachers’ ideas are ‘anchored’ in specific periods and topics of the philosophy of science. Thirty-five teachers attending a postgraduate teaching course with emphasis on the natural sciences at the Universidad del Norte (Barranquilla, Colombia) were assessed with the use of quantitative, descriptive and parametric research methods. The …
