On Polynomials Counting Essentially Irreducible Maps
The Electronic Journal of Combinatorics, 2022 We consider maps on genus-$g$ surfaces with $n$ (labeled) faces of prescribed even degrees. It is known since work of Norbury that, if one disallows vertices of degree one, the enumeration of such maps is related to the counting of lattice point in the moduli space of genus-$g$ curves with $n$ labeled points and is given by a symmetric polynomial $N_{g,

How 2.5D Maps Design Improve the Wayfinding Performance and Spatial Ability of Map Users
Informatics, 2021 Useful information can be provided by 2.5D maps that can take advantage of the additional dimension. However, aside from stereoscopic landmarks, optimal methods for presenting other essential information is unclear.

Decay of correlations in suspension semi-flows of angle-multiplying maps [PDF]
, 2007 We consider suspension semi-flows of angle-multiplying maps on the circle. Under a $C^r$generic condition on the ceiling function, we show that there exists an anisotropic Sobolev space contained in the $L^2$ space such that the Perron-Frobenius operator

On ω-essential mappings onto manifolds [PDF]
Fundamenta Mathematicae, 1991 Essential mappings have played an important role in homotopy theory as well as in continua theory. A mapping \(f: X\to M\) from a compactum into a manifold is said to be essential provided every admissible deformation of \(f\) is surjective, while a mapping \(f: X\to M\) is said to be \(\omega\)- essential provided that \(f\times \hbox{id}_ k: X\times ...

High-Precision Depth Map Estimation from Missing Viewpoints for 360-Degree Digital Holography
Applied Sciences, 2022 In this paper, we propose a novel model to extract highly precise depth maps from missing viewpoints, especially for generating holographic 3D content. These depth maps are essential elements for phase extraction, which is required for the synthesis of ...

Probabilistic Mapping Reveals Optimal Stimulation Site in Essential Tremor [PDF]
Annals of Neurology, 2022 ObjectiveThe objective of this study was to obtain individual clinical and neuroimaging data of patients undergoing deep brain stimulation (DBS) for essential tremor (ET) from 5 different European centers to identify predictors of outcome and to identify an optimal stimulation site.MethodsWe analyzed retrospectively baseline covariates, pre‐ and ...

Landsat-based remapping of the south-western Kalahari
Koedoe: African Protected Area Conservation and Science, 1990 Landsat-4 remote sensing is used to construct distortion-free maps of the almost trackless southern Kalahari Desert. These maps show the geography of natural pans, riverbeds and artificial water holes, and are improved versions of previous maps. The maps
