A variety of criteria may influence the efficacy of networks of marine protected areas (MPA) designed to enhance biodiversity conservation and provide fisheries benefits. Meta-analyses have evaluated the influence of MPA attributes on abundance, biomass, and size structure of harvested species, reporting that MPA size, age, depth, and connectivity influence the strength of MPA responses. However, few empirical MPA evaluation studies have used consistent sampling methodology across multiple MPAs and years. Our collaborative fisheries research program systematically sampled 12 no-take or highly protective limited-take MPAs and paired fished reference areas across a network spanning 1100 km of coastline to evaluate …

How Will California’S Electric Vehicle Policy Impact State-Generated Transportation Revenues? Projecting Scenarios Through 2040, Asha Weinstein Agrawal, Hannah King, H. A. “Burt” Tasaico

Mineta Transportation Institute

California faces unprecedented uncertainty about how much revenue the state will raise from a package of taxes on motor fuels and annual registration fees on light-duty vehicles that was established in 2017 by Senate Bill 1 (SB 1). The SB 1 taxes are by far the largest source of revenue that the State of California generates to support maintenance, operations, and improvements for state highways, and the funds also contribute substantially to local transportation and public transit budgets. To help policymakers navigate the uncertainty about future SB 1 transportation revenue, this study used spreadsheet models to project revenue from the …

Genetic Algorithm For Automated Parameterization Of Network Hamiltonian Models Of Amyloid Fibril Formation, Gianmarc Grazioli, Andy Tao, Inika Bhatia, Patrick Regan

Faculty Research, Scholarly, and Creative Activity

The time scales of long-time atomistic molecular dynamics simulations are typically reported in microseconds, while the time scales for experiments studying the kinetics of amyloid fibril formation are typically reported in minutes or hours. This time scale deficit of roughly 9 orders of magnitude presents a major challenge in the design of computer simulation methods for studying protein aggregation events. Coarse-grained molecular simulations offer a computationally tractable path forward for exploring the molecular mechanism driving the formation of these structures, which are implicated in diseases such as Alzheimer’s, Parkinson’s, and type-II diabetes. Network Hamiltonian models of aggregation are centered around …

Library Philosophy and Practice (e-journal)

The paper discusses the role of libraries in bridging gender inequality in Nigeria. Gender inequality is discrimination on the basis of sex or gender where one sex or gender is placed in a more advantageous position than the other. Gender inequality is one issue that has been on the front burner but efforts to tackle it are not yielding the desired results. In the light of this, the idea of libraries wading into the matter seems a better option. The paper discusses the factors responsible for gender inequality in Nigeria as follows: socio-cultural factors, socio-economic factors, socio-religious factors, socio-political factors, …

Equation Of State And Thermometry Of The 2d Su (N) Fermi-Hubbard Model, G. Pasqualetti, O. Bettermann, N. Darkwah Oppong, E. Ibarra-García-Padilla, S. Dasgupta, R. T. Scalettar, K. R.A. Hazzard, I. Bloch, S. Fölling

Faculty Research, Scholarly, and Creative Activity

We characterize the equation of state (EoS) of the SU(N>2) Fermi-Hubbard Model (FHM) in a two-dimensional single-layer square optical lattice. We probe the density and the site occupation probabilities as functions of interaction strength and temperature for N=3, 4, and 6. Our measurements are used as a benchmark for state-of-the-art numerical methods including determinantal quantum Monte Carlo and numerical linked cluster expansion. By probing the density fluctuations, we compare temperatures determined in a model-independent way by fitting measurements to numerically calculated EoS results, making this a particularly interesting new step in the exploration and characterization of the SU(N) FHM.
