The Economics Of Battery Storage For Residential Solar Customers In Southern California, John B. Broughton, Prashanth U. Nyer, Candace E. Ybarra Aug 2021

The Economics Of Battery Storage For Residential Solar Customers In Southern California, John B. Broughton, Prashanth U. Nyer, Candace E. Ybarra

Business Faculty Articles and Research

Battery storage coupled with solar panels became a consideration after the original net metering program in California (NEM 1.0) ended and gave way to the current net metering program (NEM 2.0). Under NEM 2.0, battery storage gives customers under time-of-use (TOU) rate plans the ability to store the excess electrical energy generated by their panels during sunlight hours (when electricity usage and resale rates are low) and then use that energy in the evening when rates are significantly higher. This reduces the amount of expensive electricity that the customer would have to purchase from the grid. It is widely expected …

Barcoding Us Ants: Ozarks Region - Research Highlight, Megan Woltz Aug 2021

Barcoding Us Ants: Ozarks Region - Research Highlight, Megan Woltz

The Confluence

Ants are species diverse, widespread, and critically important to their environments. For many ant species, we do not have clear data on their ranges. Barcoding US Ants is a citizen science project run by the DNA Learning Center at Cold Spring Harbor Laboratory to collect and sequence DNA from ants from around the country (CSHL, 2020). The sequences are submitted to GenBank, the DNA sequence database (NIH 2020). We formed one of the Ozarks Region teams for the Barcoding US Ants project, contributing ants from riparian forests and grassy meadows in the St. Charles, MO area. We collected 8 ant …

Terrestrial Planet Formation In A Circumbinary Disc Around A Coplanar Binary, Anna C. Childs, Rebecca G. Martin Aug 2021

Terrestrial Planet Formation In A Circumbinary Disc Around A Coplanar Binary, Anna C. Childs, Rebecca G. Martin

Physics & Astronomy Faculty Research

With N-body simulations, we model terrestrial circumbinary planet (CBP) formation with an initial surface density profile motivated by hydrodynamic circumbinary gas disc simulations. The binary plays an important role in shaping the initial distribution of bodies. After the gas disc has dissipated, the torque from the binary speeds up the planet formation process by promoting body-body interactions but also drives the ejection of planet building material from the system at an early time. Fewer but more massive planets form around a close binary compared to a single star system. A sufficiently wide or eccentric binary can prohibit terrestrial planet formation. …


The Large Area Burst Polarimeter (Leap) A Nasa Mission Of Opportunity For The Iss, Bing Zhang, Numerous Authors, See Full List Below Aug 2021

The Large Area Burst Polarimeter (Leap) A Nasa Mission Of Opportunity For The Iss, Bing Zhang, Numerous Authors, See Full List Below

Physics & Astronomy Faculty Research

The LargE Area Burst Polarimeter (LEAP) will radically improve our understanding of some of the most energetic phenomena in our Universe by exposing the underlying physics that governs astrophysical jets and the extreme environment surrounding newborn compact objects. LEAP will do this by making the highest fidelity polarization measurements to date of the prompt gamma-ray emission from a large sample of Gamma-Ray Bursts (GRBs). The science objectives are met with a single instrument deployed as an external payload on the ISS-a wide FOV Compton polarimeter that measures GRB polarization from 50-500 keV and GRB spectra from ∼10 keV to 5 …
