This study explored the mentoring experiences of doctoral students in science, technology, engineering, and mathematics (STEM) doctoral degree programs at Northwestern University. Research suggests that mentoring relationships support student success in STEM disciplines, and further, that lack of mentorship may be a barrier for female students. A mixed-methods approach employing...
In the Western classical art music tradition, a high level of music performance is achieved at the intersection of a musician's emotional, cognitive, and physical processes. Expert classical musicians have both an aural imagining of the sound they intend to produce and the physical associations of what it feels like...
Perhaps better suited for the mosh pit than the orchestra pit, David Lang’s 1991 tour-de-force for solo bass clarinet, Press Release, is a minimalist marvel. Comprised of seven “groove sections” that evolve in seemingly unpredictable ways, Lang cleverly employs monophony to tell a robust story of motivic and harmonic development....
In many dryland environments, vegetation self-organizes into bands that can be clearly identified in remotely-sensed imagery. The status of individual bands can be tracked over time, allowing for a detailed remote analysis of how human populations affect the vital balance of dryland ecosystems. In this study, we characterize vegetation change...
A longstanding goal of synthetic biology has been the programmable control of cellular functions. Central to this is the creation of versatile regulatory toolsets that allow for programmable control of gene expression. Of the many regulatory molecules available, RNA regulators offer the intriguing possibility of de novo design – allowing...
A study is conducted to determine the effects on the early hydration kinetics and
compressive strength by seeding of Portland cement and alkali-activated blast furnace
slag with a pure form of calcium silicate hydrate (C-S-H). The effects of C-S-H seeding
during the early nucleation and growth period of each type...
The segmental prestressed concrete box girder of Koror-Babeldaob (KB) Bridge in Palau, which had the record span of 241 m (791 ft.), presents a striking paradigm of serviceability loss due to excessive multi-decade deflections. The data required for analysis have recently been released and are here exploited to show how...
