Source Data For Self-Spinning Filaments For Autonomously Linked Microfibers, Dylan M. Barber, Todd S. Emrick, Gregory Grason, Alfred Crosby

Data and Datasets

Filamentous bundles are ubiquitous in Nature, achieving highly adaptive functions and structural integrity from assembly of diverse mesoscale supramolecular elements. Engineering routes to synthetic, topologically integrated analogs demands precisely coordinated control of multiple filaments’ shapes and positions, a major challenge when performed without complex machinery or labor-intensive processing. Here, we demonstrate a photocreasing design that encodes local curvature and twist into mesoscale polymer filaments, enabling their programmed transformation into target 3-dimensional geometries. Importantly, patterned photocreasing of filament arrays drives autonomous spinning to form linked filament bundles that are highly entangled and structurally robust. In individual filaments, photocreases unlock paths 16 …

Data For "Distinct Hydrologic Pathways Regulate Perennial Surface Water Dynamics In An Arid Basin", Sarah Mcknight, David F. Boutt, Lee Ann Munk, Brendan Moran

Data and Datasets

In water-stressed arid basins, questions continue to mount over the compounding impacts of anthropogenic groundwater extraction and climate-driven perturbations on groundwater-surface water interactions and the resulting resilience of ecosystem-critical surface waters. Coupling groundwater and surface water level observations with surface water extents from Sentinel-2 data provides an unprecedented opportunity to evaluate surface water connectivity with local aquifers following intense, sporadic precipitation events in arid basins. Surface water area, surface water level, and groundwater level data were analyzed for trends following precipitation, including peak lag time, post-peak decline rates, and changes in hydraulic gradients. Results indicate variable connectivity following precipitation events …

Astronomy 100: Exploring The Universe, Alexandra Pope

Astronomy Educational Materials

In this course, we will examine the power and limitations of scientific investigation. We will consider some of the fundamental questions addressed by astronomy and learn how the physical sciences can address these questions. While most of the objects astronomers study are remote, many provide new perspectives on the Earth, and the methods we use can be applied to many "real world" problems. Finally, we will explore what we know and don't know about the Universe and its constituent parts, and how we have reached those conclusions. In this context, students will be required to think about and solve conceptual …
