Spatio-Temporal Variability Of San Francisco Bay Plume From Space, Piero L. F. Mazzini, Cassia Pianca, L. Fernando Pareja-Roman, Kelly L. Cole, Ryan K. Walter, Renato M. Castelao, Elias J. Hunter, Robert J. Chant

Physics

As brackish turbid waters exit San Francisco Bay, one of the largest estuaries in the U.S. West Coast, they form the San Francisco Bay Plume (SFBP), which spreads offshore and influences the Gulf of the Farallones (GoF), an ecologically significant region in the California Current System that is also home to three National Marine Sanctuaries. This paper provides the first observationally based investigation of the spatio-temporal variability of the SFBP, using a plume tracking algorithm applied to more than two decades (2002-2023) of ocean color data from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard satellites Aqua and Terra. The …

"Check-The-Box" Enrollment Will Limit Participation In Trump Accounts: Lessons From Asset-Building Research, Jin Huang, Margaret M. Clancy, Stephen Roll, Michael Sherraden

Center for Social Development Research

As the U.S. Treasury Department considers the implementation of Trump Accounts, one proposed enrollment method is a “check-the-box” option on the federal tax return, requiring parents to actively grant permission to open an account. This policy brief draws on evidence from prior research to explain why such a check-the-box opt-in model is very unlikely to achieve full participation in Trump Accounts

Genetic Algorithm Optimization To Maximize Sensitivity Of Triboelectric Mems Accelerometers, Yu Tian, Benyamin Davaji, Shahrzad Towfighian

Mechanical Engineering Faculty Scholarship

A genetic algorithm is used to optimize the sensitivity of a triboelectric MEMS accelerometer fabricated using CMOS-compatible processes. The optimization focuses on the structural parameters of an awl-shaped serpentine microspring (ASSM) connected to the proof mass. Constraints are defined by microfabrication standards and the available chip area. Three different constraint problems are considered, and the algo- rithm yields designs with maximized sensitivity in each case. Simulations under various sinusoidal vibration scenarios show that the optimized designs significantly outperform the previous version, achieving a 2.72× improvement at 1000 Hz and up to 20× at 500 Hz.

Clonal hematopoiesis (CH) is associated with many age-related diseases, but its interaction with Alzheimer's disease (AD) remains unclear. Here, we show that TET2-mutant CH is associated with a 47% reduced risk of late-onset AD (LOAD) in the UK Biobank, whereas other drivers of CH do not confer protection. In a mouse model of AD, transplantation of Tet2-mutant bone marrow reduced cognitive decline and β-amyloid plaque formation, effects not observed with Dnmt3a-mutant marrow. Bone-marrow-derived microglia-like cells were detected at an increased rate in Tet2-mutant marrow recipients, and TET2-mutant human induced pluripotent stem cell (iPSC)-derived microglia were more phagocytic and hyperinflammatory than …

Experimental Investigation Of Strongly Coupled Finite Clusters In Two-Dimensional Dusty (Complex) Plasma, Ravi Kumar

Electronic Theses and Dissertations Archive

Dusty plasma, also known as Complex plasma, are ionized gases containing nanometers – to – micrometers sized particles (often referred as dust). The dust particles instantaneously get negatively charged due to high-mobile electrons present in the background plasma. These charged dust particles confined in a planar (two-dimensional) geometry interact through long-range forces (screened-Coulomb) exhibiting strongly coupled behavior, analogous to those in condensed matter and real 2D materials. This makes complex plasmas an ideal experimental platform to investigate the fundamental classical dynamics of strongly coupled many-body systems, such as phase transitions, configurational and thermodynamic properties.

Transcription Fidelity In The Face Of Oxidative Damage, Eastilan Gyiwah Appiah

Theses and Dissertations

It is very important that the process of transcription is correctly carried out in the cell for the faithful expression of the genetic code. However, should mistakes happen, they can result in transcription errors which interfere with the protein-making machinery of the cell. This will result in accumulation of proteins and dysfunctional proteins that have the potential of causing diseases like Alzheimer’s. Oxidative damage caused by hydrogen peroxide is known to cause transcription errors in organisms like yeast. It is therefore important to investigate the extent to which hydrogen peroxide can damage cells.
