John Lanchester’s The Wall (2019) presents a dystopic world where climate change in the form of extreme rising sea levels has caused majority landmasses to be inundated and millions people lose their homes, transforming them into environmentally displaced who try survive open seas. In novel, miraculously affected by only limited way, Britain builds ten-thousand-kilometer-long wall that circumsc...

An inexpensive way to construct a scalable display wall system is to use a cluster of PCs with commodity graphics accelerators to drive an array of projectors. A challenge is to bring off-the-shelf sequential applications to run on such a display wall efficiently without using expensive, high-performance interconnects. This paper studies two execution models for a scalable display wall system: ...

Ferroelectric domain walls are atomically sharp topological defects that separate regions of uniform polarization. The discovery of electrical conductivity in specific types of walls gave rise to "domain wall nanoelectronics," a technology in which the wall (rather than the domain) stores information. This paradigm shift critically hinges on precise nanoengineering of reconfigurable domain wall...

During a random search, resetting the searcher's position from time to starting point often reduces mean completion of process. Although many different models have been studied over past ten years, only few can be physically implemented. Here we study theoretically protocol that realised experimentally and which exhibits unusual optimization properties. A Brownian particle is subject an arbitra...

High precision skyrmion pinning by an intentionally created magnetic structure is important in manipulation. Here, we consider various types of disks. Among other findings, clarify that, terms position and potential landscape, one needs to distinguish thin-wall skyrmions from thick-wall because fundamental differences. A wall prefers areas with a weaker exchange stiffness, larger DMI constant, ...
