Well logs, measured in depth, must be tied to seismograms, processed in time, using a time-depth function. Well ties are commonly computed using manual techniques, and are therefore prone to human error. I first introduce an automatic single-well tie method that uses smooth dynamic time warping to compute time shifts that align a synthetic seismogram with a seismic trace. These time shifts are constrained to be smoothly varying. I also show that these well ties, in my example, are insensitive to the complexity of my synthetic seismogram modeling.Tying multiple wells compounds errors in single well ties, and maintaining consistency among multiple single well ties is difficult. I introduce an automatic approach to tying multiple wells that improves consistency among well ties. I first model synthetic seismograms for each well. I then create a synthetic image by interpolating the synthetic seismograms between the wells and along seismic image structure. I use smooth dynamic image warping to align the synthetic image to the seismic image and compute updated time-depth functions for each well. I then interpolate the updated time-depth functions between the wells, and map the time-migrated seismic image to depth.
Native American communities are disproportionately affected by a number of behavioral health disparities, including higher rates of depression, substance abuse, and suicide. As mobile health (mHealth) interventions gain traction as methods for addressing these disparities, they continue to lack relevance to Native American youth. In an effort to explore the design of relevant behavioral mHealth intervention for Native American communities, we have developed ARORA (Amplifying Resilience Over Restricted Internet Access), a prototype behavioral mHealth intervention that has been co-designed with Native American youth, a community advisory board, and a clinical psychologist. In this paper, we qualitatively analyze our co-design and focus group sessions using a grounded theory approach and identify the key themes that Native American community members have identified as being critical components of relevant mHealth designs. Notably, we find that the Native American youth who participated in our focus groups desired a greater level of didactic interaction with cultural and behavioral health elements. We conclude with a discussion of the significant challenges we faced in our efforts to co-design software with Native American stakeholders and provide recommendations that might guide other HCI researchers and designers through challenges that arise during the process of cross-cultural design.
Virtual Reality has become a popular entertainment medium; however, it could also potentially be useful in creating interactive experiences that act as educational tools for students. Through the use of this technology, virtual experiences facilitate the learning of various concepts through interactive simulation. This project focuses on the development of a virtual reality application that can be used to help teach different physics concepts to young students, in engaging virtual environments and further promote STEM education principles. Each level developed for the game instructs on concepts such as force, acceleration, velocity, position, etc. This paper will discuss both the specifications and design of the project as well as discuss the initial demo results and future development.
We have shown by a nuclear magnetic resonance measurement that the ureadenatured protein apoazurin becomes elongated when the synthetic crowder, dextran 20, is present, which opposes a theoretical prediction based only on the consideration of volume exclusion. To explore complex interactions beyond volume exclusion, we have employed coarse-grained molecular dynamics simulations to explain the elongated conformation of protein apoazurin resulting from the interplay of an effective attraction between a protein and crowders and the shape of a crowder. With a volume-conserving crowder, we show that the shape of a crowder provides an anisotropic direction of the depletion force, in which a bundle of surrounding rod-like crowders stabilizes the elongated conformation of apoazurin in the presence of effective attraction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
