Dataset for: A Cross-Laboratory Comparison Study of Titan Haze Analogs: Surface Energy

Xinting Yu & Jialin Li
In Titan's nitrogen-methane atmosphere, photochemistry leads to the production of complex organic particles, forming Titan’s thick haze layers. Laboratory-produced aerosol analogs, or "tholins", are produced in a number of laboratories; however, most previous studies have investigated analogs produced by only one laboratory rather than a systematic, comparative analysis. In this study, we performed a comparative study of an important material property, the surface energy, of seven tholin samples produced in three independent laboratories under a...

The WeAllWalk Data Set

German Flores & Roberto Manduchi
This data set contains time series from inertial sensors carried by blind subjects walking through pre-determined routes In two buildings in the UCSC campus. The sensors include two MetaWear CPRO (obtaining a tri-axial accelerometer and gyroscope) and two iPhone 6 containing try-axial accelerometer, gyroscopes, and magnetometers. This data set is described in the paper: Flores, German, and Roberto Manduchi. "WeAllWalk: An Annotated Data Set of Inertial Sensor Time Series from Blind Walkers", Proceedings of the...

Chemical shift-based methods in NMR structure determination

Santrupti Nerli, Andrew C. McShan & Nikolaos G. Sgourakis
Chemical shifts are highly sensitive probes that can be harnessed by NMR spectroscopists and structural biologists as conformational parameters to characterize a range of biological molecules. Traditionally, assignment of chemical shifts has been a labor-intensive process requiring numerous samples and a suite of multidimensional experiments. Over the past two decades, the development of complementary automated and computational approaches has bolstered the analysis, interpretation and utilization of chemical shifts for elucidation of high-resolution protein and nucleic...

Runoff modeling of a coastal basin to assess variations in response to shifting climate and land use: Implications for managed recharge

Sarah Beganskas, Kyle Young, Andrew Fisher, Ryan Harmon & Sacha Lozano
We quantified hillslope runoff distribution in a coastal, mixed-use basin, the Pajaro Valley Drainage Basin (PVDB), under different climate and land use conditions, evaluating the potential for distributed stormwater collection coupled with managed aquifer recharge (DSC-MAR) to improve groundwater supply. We developed dry, normal, and wet climate scenarios using historic precipitation and temperature data, and we compared contemporary land use to pre-development land use by replacing developed areas in the model with plausible native vegetation...

Photochemical model output data associated with: How to identify exoplanet surfaces using atmospheric trace species in hydrogen-dominated atmospheres

Xinting Yu
Sub-Neptunes (Rp~1.25-4 REarth) remain the most commonly detected exoplanets to date. However, it remains difficult for observations to tell whether these intermediate-sized exoplanets have surfaces and where their surfaces are located. Here we propose that the abundances of trace species in the visible atmospheres of these sub-Neptunes can be used as proxies for determining the existence of surfaces and approximate surface conditions. As an example, we used a state-of-the-art photochemical model to simulate the atmospheric...

Data associated with: Haze evolution in temperate exoplanet atmospheres through surface energy measurements

Xinting Yu
Photochemical hazes are important opacity sources in temperate exoplanet atmospheres, hindering current observations from characterizing exoplanet atmospheric compositions. The haziness of an atmosphere is determined by the balance between haze production and removal. However, the material-dependent removal physics of the haze particles is currently unknown under exoplanetary conditions. Here we provide experimentally-measured surface energies for a grid of temperate exoplanet hazes to characterize haze removal in exoplanetary atmospheres. We found large variations of surface energies...
