Many subglacial environments consist of a fine‐grained, deformable sediment bed, known as till, hosting an active hydrological system that routes meltwater. Observations show that the till undergoes substantial shear deformation as a result of the motion of the overlying ice. The deformation of the till, coupled with the dynamics of the hydrologica...

Sea level rise and coastal floods are disrupting coastal communities across the world. The impacts of coastal floods are magnified by the disruption of critical urban systems such as transportation. The flood-related closure of low-lying coastal roads and highways can increase travel time delays and accident risk. However, quantifying the flood-rel...

Climate change is intensifying coastal floods and increasing the risks of traffic disruption in low-lying, coastal communities. Efforts to understand the differential impacts of traffic disruption on communities have led to the concept of traffic resilience which captures the degree to which a traffic system can recover from disruption. Existing pr...

As sea level rises, urban traffic networks in low-lying coastal areas face increasing risks of flood disruptions. Closure of flooded roads causes employee absences and delays, creating cascading impacts to communities. We integrate a traffic model with flood maps that represent potential combinations of storm surges, tides, seasonal cycles, interan...

As sea levels rise, urban traffic networks in low-lying coastal areas face an increasing risk offlood disruption and commute delays. We hypothesize that road network connectivity rather than flood exposure governs commute delays. We integrate an existing traffic model with flood maps to identify inundated roads, simulate traffic patterns, and quant...

The distribution and drainage of meltwater at the base of glaciers sensitively affects fast ice flow. Previous studies suggest that thin meltwater films between the overlying ice and a hard-rock bed channelize into efficient drainage elements by melting the overlying ice. However, these studies do not account for the presence of soft deformable sed...

We construct a class of rank-one infinite measure-preserving transformations such that for each transformation $T$ in the class, the cartesian product $T\times T$ of the transformation with itself is ergodic, but the product of the transformation with its inverse is not ergodic. We also prove that the product of any rank-one transformation with its...

On Sendov’s conjecture, T. Chijiwa [Hiroshima Math. J. 41, No. 2, 235–273 (2011; Zbl 1232.30008)] quantifies the idea stated by V. Vâjâitu and A. Zaharescu [Bull. Lond. Math. Soc. 25, No. 1, 49–54 (1993; Zbl 0796.30004)] (and M. J. Miller [J. Math. Anal. Appl. 175, No. 2, 632–639 (1993; Zbl 0782.30007)] independently), namely that if a polynomial w...
