Obesity and type 2 diabetes are characterized by decreased insulin sensitivity, elevated concentrations of free fatty acids (FFAs), increased macrophage infiltration in adipose tissue (AT). Here, we show that FFAs can cause activation RAW264.7 cells primarily via the JNK signaling cascade TLR2 TLR4 upstream help transduce FFA proinflammatory signals. We also demonstrate F4/80+CD11b+CD11c+ bone marrow-derived dendritic (BMDCs) have heightened activity compared with F4/80+CD11b+CD11c−...
Abstract Electric vehicles (EVs) are experiencing a rise in popularity over the past few years as technology has matured and costs have declined, support for clean transportation promoted awareness, increased charging opportunities, facilitated EV adoption. Suitably, vast body of literature been produced exploring various facets EVs their role energy systems. This paper provides timely comprehensive review scientific studies looking at aspects EVs, including: (a) an overview status...
California has adopted a substantial number of electric vehicles over the last decade but there are many challenges associated with electrification vehicles, including how they interact electricity grid. We employ real-world feeder circuit level data in from PG&E to measure capacity local feeders. model adoption down census block and take advantage vehicle charging simulate future loading on circuits throughout Northern California. In our highest scenario 6 million California, we find that...
Abstract Carbon accounting is important for quantifying the sources of greenhouse gas (GHG) emissions that are driving climate change, and increasingly being used to guide policy, investment, business, regulatory decisions. The current practice from consumed electricity, guided by standards like GHG protocol, uses annual-average grid emission factors, although previous studies have shown carbon intensity varies across seasons hours day. Previous case can bias inventories, but none this...
Vehicle electrification has been identified as one of the most important roles in decreasing greenhouse gas (GHG) emissions transportation. Proper placement charging infrastructures and management activities is key to ensuring environmental benefits from widespread adoption electric vehicles (EVs). By employing empirical travel trajectory data, this paper investigates how individual dwelling patterns can affect distribution spatial temporal opportunities for vehicle charging, well...
California, a pioneer in EV adoption, has enacted ambitious electric vehicle (EV) policies that will generate large burden on the state’s distribution system. We investigate statewide impact of uncontrolled charging networks at scale and high granularity, by employing an profile projection combines travel demand model, adoption real-world data. find substantial need for infrastructure upgrades 50% feeders 2035, 67% 2045. The system across California must upgrade its capacity 25 GW 2045,...
The United States Corporate Average Fuel Economy (CAFE) standards and Greenhouse Gas (GHG) Emission are designed to reduce petroleum consumption GHG emissions from light-duty passenger vehicles. They do so by requiring automakers meet aggregate criteria for fleet fuel efficiency carbon dioxide (CO2) emission rates. Several incentives manufacturers sell alternative vehicles (AFVs) have been introduced in recent updates of CAFE/GHG policy sold 2012 through 2025 help encourage a technology...
The transportation sector is a major source of greenhouse gas (GHG) emissions. Shared autonomous electric vehicles (SAEVs) have the potential to mitigate emissions, but effect can be highly dependent on growth and operation SAEV fleet as well its interaction with evolving power system. In this study, we simulate travel charging behaviors SAEVs based empirical data ride-hail service operations, integrate Grid Optimized Operation Dispatch (GOOD) model, taking into account expansion renewable...
California has a many activities targeting specific sectors to mitigate climate change. This study models several scenarios of future electric vehicle emissions in the state and explores untapped policy opportunities for interactions between sectors, specifically transportation electricity grid. As vehicles become more prevalent, their impact on grid is directly related aggregate patterns charging—even without vehicle-to-grid services, shifting charging can be potentially important resource...
The recent growth of new mobility services such as car-sharing (ZipCar, Car2Go) and ride-hailing (Uber, Lyft) has interesting implications for vehicle technologies. We explore the users their relation to electric vehicles preferences by analyzing two large-scale service surveys. A number categories (car-share usage, ride-hail commute mode, demographics, current attributes, environmental attitudes, technology life-stage information) are examined in order determine likelihood a respondent...
A national network of DC Fast Charging infrastructure (DCFC) corridors can facilitate connectivity and long-distance travel using battery electric vehicles (BEVs). Optimal locations such facilities are where BEV drivers have easy access to charging will not make any deviation from their pre-planned trips. Such optimally located corridor DCFCs usually in remote, underserved communities immediately next a highway they lack the advantages shared utility an urban setting. Therefore, we find that...
We investigate where, how, and when investments in hydrogen infrastructure is cost optimal for the Californian market. Impacts of establishing hubs analyzed together with influence sector coupling renewable policies.
Long-haul truck electrification has attracted nascent policy support, but the potential health and climate impacts remain uncertain. Here, we developed an integrated assessment approach with high spatial-temporal (km hourly) resolution to characterize causal chain from operation charging loads, electricity grid response, changes in emissions atmospheric concentrations, resulting across United States. Compared future diesel trucks, electrified trucking's net benefits are concentrated only...
Abstract The urgent need to decarbonize the transportation sector combined with falling battery prices has spurred industry and policy interest in long-haul truck electrification. charging behavior resulting loads from electrified freight trucks are crucial for smooth operation of electric grid have far-reaching environmental impacts (e.g., greenhouse gas other air pollutant emissions). However, aggregate energy impact a fleetwide shift trucking not been explored. This study combines design...
As the transportation sector undergoes three major transformations—electrification, shared/on-demand mobility, and automation—there are new challenges to analyzing impacts of these trends on both system power sector. Most models that analyze requirements fleets shared autonomous electric vehicles (SAEVs) operate at scale an urban region, or smaller. A quadratically constrained, quadratic programming problem is formulated, designed model SAEVs a national scale. The size SAEV fleet, necessary...
