Advanced imaging via multiplexed sensing and compressive sensing
… on advanced imaging systems using multiplexed sensing and compressive sensing (CS). Conventional cameras (e.g., pin-hole and lens cameras) follow the one-object-point-to-one-image-point or one-to-one (OTO) mapping model. Multipled sensing and compressive sensing attempt to improve conventional …

Compressive Sensing
… certain key elements in the area of compressive sensing. As a sub-discipline of signal processing, compressive sensing is concerned with both sampling and reconstruction techniques. In this expository, sampling will center on random matrices and expander graphs, while reconstruction will use …

Social sensing games
We introduce Social Sensing Games (SSGs), a new method for collecting data about social relationships, and present an algorithm that can be used to efficiently infer information from the output of the games. The main purpose of this new method is to use people's online interactions to learn about …

Hypothalamic Nutrient Sensing
Nutrient sensing neurons are unique in coupling changes in the concentration of nutrients to changes in neuronal activity. These neurons typically exist in regions of the brain where the blood brain barrier is fenestrated, such as the arcuate nucleus of the hypothalamus. Glucose and leucine are …

Sensing the Threshold
The sacred and the profane: a dichotomy that can only exist through the thresholds within. In a world that's drowning in the profane, we yearn for the ephemeral, in which our mind, body, and soul emerge out of the mundanity of day-to-day life, and into something beyond. We search for the art, seek …

Design And Analysis Of Reconfigurable Sensing Antennas For Wireless Sensing Applications
Reconfiguration sensing antenna (rsa) is a novel antenna concept, which not only can transmit or receive radio waves but also can sense the surrounding environment. The environment sensing is realized by reconfiguring the antenna's characteristics, such as resonant frequency, and radar cross …

Matching remote sensing images.
… The main objective is to register two remote sensing images taken at different times. First, some distinctive features are extracted and matched then, these matched features are used as marking points in defining a geometric mapping function. Once registered, the reference image can be used as …

Light-sensing in bacteria
… research focused on a number of different light-sensing systems in different bacteria: PpaA in Rhodobacter sphaeroides, PixD-PixE in Synechocystis sp. PCC, and the known light-receptors in Rhodospirillum centenum. PpaA from R. sphaeroides had previously been shown to be a heme-binding protein, …

Induced-Fit Anion Sensing
… is significant interest in their binding and sensing. In induced-fit anion sensing, the binding of an anion causes a shift in the equilibrium of conformers of the molecule, which in turn may lead to a change in a physical property. In this thesis four experimental chapters describe the …

Sensing of Picornavirus Infections
The sensing of viral infection through pattern recognition receptors is necessary to trigger an immune response through the expression of interferons (IFNs) and cytokines. For RNA viruses, which replicate in the cytoplasm, the cytoplasmic RIG-I like receptors are responsible for this sensing. The …

Sensing in biological systems
… In Chapter 2, we took a unique approach to Ca²⁺ sensing with a rationally designed sensor which possess all the desirable characteristics (brightness, photostability and red fluorescence emission) of both the traditional and spiropyran-type sensor. This was accomplished by combining a traditional …

Four-Dimensional Coherence Sensing
… arrays have made new combinations of optical sensing and digital processing possible. Using the framework of optical spatial coherence theory, this thesis proposes and investigates new combinations of optics and algorithms with capabilities not possessed by standard lens-based cameras. This …

Sensing With Communication Constraints
For distributed averaging, we design distributed algorithms that allow each node to compute the average of all numeric values (which could, for example, be measurements) initially recorded in the network when both communication and storage at sensors are constrained. These algorithms also have …

Ultratrace Neurotransmitters SERS Sensing
… modes of NTs molecules and ultratrace NTs SERS sensing are discussed in detail. Further exploration of SERS substrates in the format of oil/water interfacial film will also be reported. The SERS application integrated with microfluidic techniques will be discussed in the final part of this …

Understanding Membrane Curvature Sensing
… I identified AKT PH domain as a new curvature-sensing domain. Finally, using the ENTH domain of Epsin1 that causes vesicle budding, I demonstrated that this method can also be used to study membrane remodelling. Trafficking involves generation and sensing of membrane curvature combined with …
