Exact genome alignment
… align the genome sequences accurately. Sequence alignment helps to identify regions of similarity between the sequences to establish their functional, evolutionary and structural relationship. The thesis investigates the performance of two sequence alignment programs LASTZ, a hash table based …

Vision by alignment
… information to resolve ambiguity. I propose an alignment model for vision, in which computational specialists eagerly share state with their neighbors during ongoing computations, availing themselves of neighbors' partial results in order to ll gaps in evolving descriptions. Connections between …

Out of Alignment
This thesis is an exploration of relationships made between angular elements for the purpose of discovering the spatial results that those explorations create. The media used to develop this thesis are two dimensional linear compositions, three dimensional modeling, and photography.

Goal alignment: re-analyzing value alignment problems using human-aware AI
While the question of misspecified objectives has gotten much attention in recent years, most works in this area primarily focus on the challenges related to the complexity of the objective specification mechanism, for example, the use of reward functions. However, the complexity of the objective …

Transparent Value Alignment: Foundations for Human-Centered Explainable AI in Alignment
Alignment of autonomous agents' values and objectives with those of humans can greatly enhance these agents' ability to act flexibly to safely and reliably meet humans' goals across diverse contexts from space exploration to robotic manufacturing. However, it is often difficult or impossible for …

Integrated multiple sequence alignment
… for automated and manual multiple sequence alignment: existing alignment algorithms are made more easily accessible and new algorithms are designed for difficult cases. Firstly, we introduce the QAlign framework, a graphical user interface for multiple sequence alignment. It comprises …

The alignment of screens
… surfaces and the gaps in between them articulate alignments of people and things with displays that, in practice, always leave something out of sight. Rather than losing touch with screens by reducing them to surfaces, in other words, I am interested in alternative screen configurations. For this …

Elastically averaged precision alignment
One of the most important steps in designing a machine is the consideration of the effect of interfaces between components. A badly designed interface can vary from costly difficulties such as additional control or calibration to machine failure. For precision assemblies such as automobile engines, …

Alignment- and Alignment-refining Algorithms: Effects on Branch-length Estimation and Selection Pattern Analyses
… consists of a study of the effects of multiple-alignment method on phylogenetic analyses. First, I investigated the effects of multiple-sequence alignment quality on branch-length estimation, which can influence downstream bioinformatic analyses such as estimating rates of evolution and …

Protein-Protein Interaction Network Alignment
… as edges. Protein-protein interaction network alignment is very important in identifying protein complexes and predicting protein functions. Many algorithms based on graph theory have been developed to improve the accuracy of alignment, but due to the sparsity of protein-protein interactions, …

Network alignment on big networks
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-04-06 without embargo terms

Crystal alignment in sea ice
… time at which the ice solidified. This yields an alignment relaxation time which has been related to the fluid velocity outside the boundary layer. Thus it is possible to predict the direction and strength of the c-axis alignment from knowledge of the mean current. Alternatively, the effective …

Carbon Nanotube Alignment within Macrostructures
The enhancement of alignment in carbon nanotube (CNT) assemblies is an important challenge in scaling up their exceptional properties from the nano- to the macroscopic level. In this work, theoretical and computational studies were performed to understand how CNT alignment is measured, how it …

Enabling imagination through story alignment
… and effective story comparison through story alignment. My algorithms, implemented into the Genesis system, allow the comparison and combination of stories which is a step towards enabling imagination in artificial intelligence. This capability is made possible by reducing the runtime of a …

Read alignment using deep neural networks
Read alignment is the process of mapping short DNA sequences into the reference genome. With the advent of consecutively evolving "next generation" sequencing technologies, the need for sequence alignment tools appeared. Many scientific communities and the companies marketing the sequencing …

Alignment of contrast enhanced medical images
The re-alignment of series of medical images in which there are multiple contrast variations is difficult. The reason for this is that the popularmeasures of image similarity used to drive the alignment procedure do not separate the influence of intensity variation due to image feature motion and …

Lifespan changes in covert attention alignment
… childhood through old age. Strategic attention alignment becomes more efficient in early adulthood. Children have difficulty sustaining attention at locations specified by information cues and seniors have difficulty using the information rapidly. Both children and seniors are less able to use …
