Antarctic firn is critical for ice-shelf stability because it stores meltwater that would otherwise pond on the surface. Ponded meltwater increases the risk of hydrofracture and subsequent potential ice-shelf collapse. Here, we use output from a firn model to build a computationally simpler emulator that uses a random forest...
In today’s sociopolitical climate, many marginalized communities face unique challenges and yet triumph in carving a pathway toward happiness and self-acceptance. Among those resilient individuals are Black gay men, who experience the intersectionality of race, gender, and sexuality, creating an array of experiences. This collaborative autoethnography explores the distinct...
This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] Quantum mechanics is a field often considered very mathematical, abstract, and unintuitive. One way some instructors are hoping to help familiarize their students with these complex topics is to have the students see quantum...
We explore universality and phases of matter in hybrid quantum dynamics combining chaotic time evolution and projective measurements. We develop a unitary representation of measurements based on the Stinespring theorem, which we crucially identify with the time evolution of the system and measurement apparatus, affording significant technical advantages and conceptual...
Recent work has shown that a self-correcting quantum memory can exist in three spatial dimensions, provided that it is protected by a 1-form symmetry. Requiring that the dynamics of a system obey this type of symmetry is equivalent to enforcing a macroscopic number of symmetry terms throughout the bulk. In...
Mechanical engineers have an important role in contributing to a more sustainable future. However, the extent that sustainability is currently being integrated into mechanical engineering (ME) curricula is unclear. This research characterized sustainability integration in undergraduate ME courses at 100 universities. Criterion-based selection resulted in a range of institution types...
Although diminishing newsrooms—and gaping holes in community news coverage—have been acknowledged in the US for over a decade, the term “news desert” did not widely emerge in discourse among industry professionals to refer to places that lacked news outlets until the fall of 2018. While much work in various disciplines,...
In the montane western United States, where the majority of downstream water resources are derived from snowmelt, a warming climate threatens the timing and amount of future water availability. It is expected that the fraction of precipitation falling as snow will continue decreasing and the timing of snowmelt will...
Geospatial datasets derived from remote sensing data by means of machine learning methods are often based on probabilistic outputs of abstract nature, which are difficult to translate into interpretable measures. For example, the Global Human Settlement Layer GHS-BUILT-S2 product reports the probability of the presence of built-up areas in...
Although previous studies have shown that the near-surface environmental conditions on Mars may permit salt deliquescence and therefore brine production, there is significant uncertainty in the kinetics of the process. Indeed, experimental studies have shown that deliquescence is either very rapid or too slow to be relevant to Mars....
