Ultra-Low Frequency Standing Alfven Waves: Global Magnetospheric Modeling of Resonant Wave-Wave Interactions.

Alfven waves are an important energy transport modality in the collisionless plasmas that dominate Earth's magnetosphere. While wave-particle interactions are well understood, the mechanisms that govern wave-wave interactions and their associated phenomenological impacts are still poorly understood and have received little attention. To examine both linear and nonlinear resonant mode coupling, we use the Space Weather Modeling Framework (SWMF) with a resistive, ionospheric inner boundary with ideal MHD governing equations in order to explore the excitation of field line resonances and the stability of standing Alfven waves along the magnetopause by using synthetic upstream solar wind drivers. In reproducing the essential features of broadband FLRs, we found multi-faceted local time FLR asymmetries not exclusively determined by correlated asymmetries in the compressional driver. In examining the stability of transverse magnetopause surface waves, we found evidence of an oblique parametric decay instability exciting large-scale, counterpropagating magnetotail kink modes via ponderomotive forces mediated by transverse magnetic beat waves. The latter is responsible for a backward-propagating compressional wave along the magnetopause. These magnetotail waves bear the signature of slow magnetosonic-shear Alfvenic coupling with associated density holes and soliton-like transverse waves with strong field-aligned currents. Our results have significant implications for magnetotail dynamics and the energization of radiation belts in the dayside magnetospheric cavity and is the first study to examine a) negative energy surface waves, b) parametric decay instability of transverse magnetopause surface waves, c) ponderomotive forces via magnetic beat waves, d) the coupling of MP surface waves to magnetotail kink mode waves, e) counterpropagating kink mode waves, and f) the coupling of slow magnetosonic and transverse wave modes.PhDApplied PhysicsUniversity of Michigan, Horace H.

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Special Operations in littoral warfare

Increasingly, changes in the international environment, coupled with a reduction in U.S. military force structure, have shrunk the size and number of deploying amphibious and carrier battle groups. The impact on the reduced size of the deploying battle groups is that they are being tasked to respond to a larger diversity of military operations. Within those operations Special Operations Forces (SOF) could provide flexibility and a wide range of capabilities which could be used by the battle group commander to increase his area of influence in operations during a peacetime crisis response. The purpose of this thesis is to investigate the characteristics presented by operations in the littoral region and to examine the unique capabilities SOF provide the battle group commander in littoral operations. This thesis will then examine the degree to which mission success in littoral operations might be affected by the effective integration and use of SOF in conjunction with Naval Expeditionary Forces within the current naval carrier battle group command and control organization.http://archive.org/details/specialoperation1094531307NANAU.S. Navy (U.S.N.) author
