Transport of soft materials in crowded environment
… study the transport of soft material objects in crowded environment. Delaunay triangulation and wavelet transform were adapted to extract more information from images of macromolecules with irregular shapes and heterogeneous transportation dynamics. Systems studied are actively transported …

Protein interactions in vitro and in the cell
The cell is a complex crowded environment containing up to 300 mg/mL bio-macromolecules. In this environment proteins are far from isolated systems and interact with many other biological molecules they encounter. In recent years, better instrumentation and greater computing power have enabled …

Probing Plant Metabolism: The Machineries of [Fe-S] Cluster Assembly and Flavonoid Biosynthesis
… interactions are possible. Because of the crowded environment of the cell, there must be structured and ordered mechanisms that control metabolic pathways. The following work will examine two metabolic pathways, one that is ubiquitous among living organisms and another that is entirely …

Implementation of Vision-Based Navigation for Pedestrian Environments
… pipeline for autonomous navigation in pedestrian environments, utilizing only a single front-facing RGB-D camera and tracking camera as perception devices. This pipeline utilizes 3D monocular object tracking in combination with an advanced Kalman-filter based geometric tracking scheme to track …

Millimeter wave wearable communication networks : analytic modeling and MIMO support
… streaming among wearable devices in a densely crowded environment is challenging. This is primarily due to bandwidth scarcity when many users operate multiple devices simultaneously. The millimeter wave (mmWave) band has the potential to address this bottleneck, thanks to more spectrum and less …

Investigating the parameters affecting the sensitivity of a protein nanopore sensor
… first parameter to consider is the cellular crowded environment. Although, cellular crowding is known to have significant implications in the kinetics and equilibrium of biopolymer interactions, it has been poorly investigated in nanopore sensing. Here, we show that the presence of …

A Service Robot for Navigation Assistance and Physical Rehabilitation of Seniors
… are not confident to move alone, especially in crowded environment and for long journeys, highly reducing the quality of their life. We propose a new generation of robotic walking assistants whose mechanical and electronic components are conceived to optimize the collaboration between the robot …

Ultrafast 2D IR spectroscopy of membrane peptide systems
… between the intercellular and extracellular environment, playing a critical role in numerous biological processes. Recent research has challenged the long-standing "fluid mosaic model," representing membranes as densely packed, heterogeneous environments. Within these complex membranes are …

Dynamics of Micro-Particles in Complex Environment
… (JCMs) and magnetic clusters, in complex environment are studied using numerical simulations. The self-diffusiophoresis of JCMs in a confined environment is studied first. Overall, the translocation of a JCM through a short pore is slowed down by pore walls, although the slowdown is far …

Essays on Marketing Strategies in the Context of Interdependent Consumption
… for exclusivity or to receive a service in a non-crowded environment due to better experience and service delivery. Utilizing a repeat purchase signaling model I show that, consistent with prior literature, the high quality firm signals its quality by making its product scarce as well as charging …

Mechanisms of Adsorption and Surface-Mediated Aggregation of Intrinsically Disordered Protein Tau at Model Surfaces
… of tau protein aggregation. The macromolecular environment, including the presence of surfaces such as the cell membrane, and the presence of macromolecules in a crowded environment, has been implicated in the aggregation of tau protein. However, the exact role of surfaces in modulating Tau …

Insights into the structure and aggregation of lens crystallins and other aggregation-prone proteins
… isoforms have been characterised under crowded and oxidative conditions, respectively. Finally, the conformational heterogeneity of model proteins was studied by capillary electrophoresis as a prelude to such studies on the more complex crystallins. Chapter 2 details the structural …

Phase Phenomena of Proteins in Living Matter
… must fold and function in the immensely complex environment of a cell, i.e. the cytoplasm—this is far from the ideal test-tube setting of a dilute solution. Here, this thesis answers an important question at the interface of physics and biology: how does the crowded cellular environment influence …

The formation of high-mass stars and stellar clusters in the extreme environment of the Central Molecular Zone
… -- how sensitive is star formation to the local environmental conditions? How do massive and dense stellar clusters form, and how does this crowded environment influence the stars that form within it? How do the most massive stars form and is there an upper limit to the stellar initial mass …
