Small-scale domes with circumferential aprons and concentric aureoles in western Arcadia Planitia (34–41°N, 167–179°E) near Tyndall crater were examined using a suite of datasets including CRISM, THEMIS IR, HiRISE, CTX. Previous studies based primarily on photogeologic evidence suggested that these analogous to terrestrial felsic cryptodomes extrusive lava domes. The have also been CRISM visibl...

Lava dome collapse hazards are intimately linked with their morphology and internal structure. We present new lava emplacement models that use calibrated rock strengths allow material behaviour to be simulated for three distinct units: (1) a ductile, fluid core; (2) solid upper carapace; (3) disaggregated talus slopes. first show relative proportions of depend on strength, piles can act as an u...

Research on logic based bottom-up parsing in particular, around Constraint Handling Rule Grammars [3]is uncovering shape as an untapped fertile ground for natural language processing in general, and for bottom-up parsing and grammar induction in particular [1]. For instance, commonalities between shapes implicit in molecular biology strings and in natural language strings motivated an award win...

We introduce the method of punctured containers, which geometrically relates volumes and centroids of complicated solids to those of simpler punctured prismatic solids. This method goes to the heart of some of the basic properties of the sphere, and extends them in natural and significant ways to solids assembled from cylindrical wedges (Archimedean domes) and to more general solids, especially...

As the industrial hemp ( Cannabis sativa L.) market grows, there is a need for methods to clonally propagate parental breeding stock and new cultivars. Information lacking on vegetative cutting propagation of hemp. We evaluated how environment (intermittent mist vs. subirrigation under humidity dome), indole-3-butyric acid (IBA) formulation (talc rooting powder IBA in solution), concentration (...
