Target search methods for space situational awareness
This work studies methods to detect target in an orbit around the Earth using a space based sensor. Searching for a target among a large set of candidate orbits is a difficult and time consuming problem. Considering orbital dynamics, sensor uncertainties and the initial size of candidate location …

An analysis of EEG signals present during target search
Recent proof-of-concept research has appeared highlighting the applicability of using Brain Computer Interface (BCI) technology to utilise a subjects visual system to classify images. This technique involves classifying a users EEG (Electroencephalography) signals as they view images presented on a …

An Adaptive Approach to Optimal Sparse Mobile-target Search Planning using Heterogeneous Agents
Planning an effective search for locating mobile-targets is essential in a variety of scenarios (e.g., search and rescue, environmental monitoring, law enforcement, etc.). Effective planning is especially important when resources are sparse (i.e., they are insufficient to search a significant …

Towards understanding molecular, sub-molecular and atomic mechanisms of facilitated target search on DNA
… factors and DNA repair enzymes find their target sites among billions of nonspecific sites on the genomic DNA. The mechanisms that allow proteins to rapidly scan DNA have been the subject of considerable interest in molecular biophysics since the early 1970s. However, experimental and …

Complexity of transcription factor target search: effect of DNA natural decoys and DNA methylation through interplay with methyl-CpG-binding proteins on transcription factor DNA association
… contains numerous sites that are similar to the target sequences recognized by transcription factors. These sequences potentially serve as natural decoys that sequester transcription factors. The impact that these decoys have on transcription factor target search is largely unknown, and various …

An exploration of conceptual similarity in multiple target visual search
Visual search studies generally suggest that multiple target visual search is more difficult and less efficient than traditional single target search, with costs to both RT and accuracy. Typically, these studies use dual target trials and abstract stimuli. A study by Laderoute (2021) using varying …

Exploring the Relationship between Long-Term Memory and Attention through Attentional Templates
… by work which has demonstrated that multiple searches for the same target changes contralateral delay activity (CDA), an event-related potential that is the putative marker of the amount of information maintained in VWM. It has been suggested that the disappearance of the CDA with an …

Single-molecule methods for an improved understanding of biophysical interactions: from fundamental biology to applied nanotechnology
… require proteins to recognize a specific DNA target-site. This search process is well-documented for monomeric proteins, but not as well understood for systems that require dimerization or oligomerization at the target site for activity. We present a single-molecule study of the target-search …

Real-time Prediction of Dynamic Systems Based on Computer Modeling
… only the observation information but also the target motion information, has hen been proposed. The proposed DTFLOP modeling is validated using the proposed parallel grid-based RBE technique with the GPU implementation by comparing the estimated time cost with the actual time cost of the …

Characterizing interactions between cAMP responsive element binding protein 1 and methyl-CpG-binding protein 2 as a potential transcriptional activation complex
… effects of nucleosomes on transcription factor target search. In summary, we establish purification protocols for CREB1 and MeCP2, preparation protocols for nucleosome core particle reconstitution, and examine interactions between CREB1 and MeCP2 through quantitative and qualitative methods.

An investigation of the mechanism of information reduction
… the stimulus was varied. Study 2 realised a new target search task (TST) in which IR also developed, generalising the strategy beyond the original alphabet arithmetic task (AAT). The third study of the thesis investigated further attributes that could inhibit or facilitate reduction. The final …

Exploring Trade-offs and Emergent Properties of Heterogeneous Swarms of Maritime Robot Systems through Empirical Analysis and Application-Driven Experiments
… approach to addressing challenges such as searching for and tracking moving targets, offering advantages like robustness and scalability over single-agent solutions. Current maritime searching and tracking strategies typically involve employing predetermined paths for exploring the search …

Active Information Gathering Using Distributed Mobile Sensing Networks
… information gathering turns into a multiple target tracking (MTT) problem. Usually, an MTT tracker is utilized to recursively estimate both the number of targets and the state of each target. In order to estimate more efficiently and reliably, sensors must balance exploiting current knowledge …

NMR Studies on Kinetics of Processes Involving DNA-Binding Proteins
… DNA molecules in Chapter III. The facilitated target search process in a very challenging problem, which defines the function of different DNA binding proteins and the kinetic shortcuts taken by these macromolecules in speeding up the target location. In Chapter IV the NMR based methods used to …

Identification and characterisation of microRNAs expressed in articular cartilage and osteoarthritis
… genome microarray combined with computational target search analysis. A number of likely targets obtained from the array were further validated by subcloning and luciferase assays, resulting in the discovery of ITGA5 as a target of candidate novel 11. The outcomes from this research provide us …

Biophysical Analyses of Intermolecular Ion-Pairs in Protein-DNA Complexes
… investigate the role of ion-pair dynamics in DNA target search. Using fluorescence-based stopped flow kinetics experiments, we show an increase in sliding length for the Antp homeodomain in the presence of Ficoll. Furthermore, through NMR spectroscopy-based diffusion experiments, we show that 3-D …

The Effects of Task Criticality and Target Modality on a Simulated Battlefield Search Task
… were more effective forms of instruction for a target search task in a critical scenario (defined as a task with life-threatening consequences). Forty participants were asked to participate in this study. Twenty participants had military deployment experience and twenty participants were …

Prioritized Sensor Detection with Communication Constraints: A Cyber-Physical Systems Approach
… integration of capabilities, or possible large search areas need to be investigated. A heterogeneous team allows for the robots to become ``specialized'' in their abilities and therefore accomplish sub-goals more efficiently which in turn makes the overall mission more efficient. In Part I of …
