Gene regulation is a principle tool that all organisms utilize to control development, growth, and responses to environmental conditions. Understanding how organisms orchestrate the spatiotemporal regulation of gene expression remains a fundamental...

Background. It is not clear whether a generic quality-of-life instrument can appropriately represent severe mental illness in an economic evaluation. This problem is particularly salient for resource-allocation decisions where policymakers compare...
Today''s fastest microprocessors, logic chips, and even memory chips employ dynamic logic as the key part to achieving advanced performance. Dynamic logic only retains the correct data state briefly and is far less robust than previous technologies...
The chemistry of indole can be reversed and redirected by the addition of powerful electron-withdrawing groups. Incorporation of a nitro group at C-2 or C-3 renders the adjacent carbon susceptible to nucleophilic attack. Nitro, cyano, and...
Evolutionary Computation (EC) is one of the most advanced computational techniques. It has been frequently and successfully used to find good solutions to many complicated optimization problems with limited computational resources. EC is the...

Problem Statement Patient safety in the modern hospital is supported by multiple human and technological systems, and this type of high-risk/high-complexity domain requires multiple layers of protection against harm. This fault-tolerant approach is...
Functional neuroimaging has confirmed a high degree of localization of function in the cerebral cortex of man. In contrast, microstructural analysis has contributed very little to the topographical characterization of cortical areas. In this work I...
The proliferation of mobile devices and other consumer products has greatly expanded the market for CMOS image sensors. This in turn has promoted a trend of continued improvement in image sensor performance, as companies seek to gain an advantage...
Hematopoietic stem cells (HSCs) balance self-renewal with the continuous production of the suitable numbers of lineage-restricted progenitor cells. In this work we demonstrate that the Mixed lineage leukemia 1 (Mll1) gene is essential for this...
In the Firefighter Problem, a fire starts at a vertex of a graph, and in discrete time units, it spreads from burned vertices to their neighbors, unless they are protected by one of the f firefighters that are deployed every turn. Once burned or...
The iodothyronine deiodinases, D1, D2, and D3, play a crucial role in determining the circulating and intracellular levels of active and inactive thyroid hormone (TH), and thus have a major effect on TH action during development and adulthood. The...

Visual interpretation of the EEG associated with an epileptic seizure (ictal EEG) can be cumbersome and sometimes misleading, due to rapid seizure spread, limited spatial resolution and the fact that signals of interest are often obscured by...

Intracellular transport between the ER and Golgi is mediated by vesicles that bud from donor membranes and then fuse with acceptor membranes. Bi-directional vesicle transport maintains distinct organelle composition through a process known as...
Genetic and immunological tools have been used to study two protozoan parasites, Plasmodium falciparum and Toxoplasma gondii. Toxoplasma gondii provides an excellent model for the study of protozoan parasite biology. Plasmodium falciparum causes...
An important mode of stabilization of cations in biochemical reactions is interaction with the π systems-of aromatic residues. As part of an investigation of the interaction of carbocations with aromatic π systems, a study of various model...
Outcome assessment (Medical care). ; Aortic valve -- Surgery -- Complications. ; Aortic valve -- Surgery -- New England. ; Cardiovascular instruments Implanted.
Aortic valve disease is a frequent and serious disorder. Although aortic valve replacement (AVR) is arguably the only effective treatment, important issues remain unresolved in the care of patients with this disease. Recent studies have focused...
This research attempts to combine known methodology with new chemistry towards the preparation of extended polycyclic aromatic hydrocarbons (PAH). The generation and Diels-Alder trapping of 1,7- and 2,6-naphthalene bisarynes was attempted for the...

A decline in population growth as the abundance of a species increases can stabilize population size. In Western Borneo, I found evidence for such density dependence in juveniles of the genus Shorea (Dipterocarpaceae) that dominates southeast...
Modern distributed systems scatter sensors, storage, and computation throughout the environment. Ideally these devices communicate and share resources, but there is seldom motivation for a device''s owner to yield control to another user. We...
Antibodies are known to be a primary correlate of protection in almost all current vaccines, and thus evaluating the antibody response is of critical importance in attempting to predict the efficacy of novel vaccine candidates. Historically...
