Earth Surface Processes and Landforms, Volume 49, Issue 14, Page 4587-4609, November 2024.The development of the Critical Zone (CZ) environment in the expanding Forni Glacier forefield after glacier retreat, has been analysed over time since the end of the Little Ice Age by considering different sectors: air (katabatic winds), forest (ecesis times and colonization patterns), surface waters (soil moisture patterns and water isotopic ...

Journal of Geophysical Research: Planets, Volume 129, Issue 11, November 2024.Abstract Near the Noachian‐Hesperian boundary (∼3.6 billion years ago), most of Mars' near‐surface water inventory was likely frozen in large southern ice sheets and Mars' CO2 atmosphere had eroded enough that it began to periodically collapse. Here, I report model results showing that thermal blanketing of a southern H2O ice sheet by a CO2 ice cap ...

Restoration Ecology, Volume 32, Issue 8, November 2024.The International Principles and Standards for the Ecological Restoration and Recovery of Mine Sites were used to assess the restoration quality of one of the world's largest mines, located in the world's most biodiverse temperate forest. Quantitative analysis of longitudinal data spanning 35 years scored restoration quality at 2‐stars against a 5‐star

Snowmelt and subsurface heterogeneity control tree water sources in a subalpine forest
Ecohydrology, Volume 17, Issue 7, October 2024.Abstract In high mountain areas, snowmelt water is a key—yet fading—hydrological resource, but its importance for soil recharge and tree root water uptake is understudied. In these environments, heterogeneous terrains enhance a highly variable availability of soil and groundwater resources that can be accessed by plants.

arXiv, 2005 We define extension maps as maps that extend a system (through adding ancillary systems) without changing the state in the original system. We show, using extension maps, why a completely positive operation on an initially entangled system results in a non positive mapping of a subsystem.

Morphological and Structural Characterization of Shortening Landforms on Mars
Journal of Geophysical Research: Planets, Volume 129, Issue 10, October 2024.Abstract The lithosphere of Mars accommodates horizontal shortening through folding and faulting, producing landforms described as wrinkle ridges or lobate scarps. Despite this nomenclature, we lack a deep understanding of the drivers of morphological differences observed between landform types.

On Net Maps: Examples and Nonexistence Results [PDF]
arXiv, 2015 A Thurston map is called nearly Euclidean if its local degree at each critical point is 2 and it has exactly four postcritical points. Nearly Euclidean Thurston (NET) maps are simple generalizations of rational Lattes maps. We investigate when such a map has the property that the associated pullback map on Teichmuller space is constant.

Variations of completely bounded maps on operator spaces [PDF]
arXiv, 2018 We introduce weighted cb maps and $\Lambda_\mu$-cb maps on operator spaces which are generalizations of completely bounded maps and a certain class of bilinear maps on operator spaces which we call $\lambda_\mu$-cb bilinear maps. Some basic properties of these maps and an operator space tensor product associated to $\lambda_\mu$-cb bilinear maps have ...

Journal of Geophysical Research: Planets, Volume 129, Issue 8, August 2024.Abstract Mare domes (interpreted to be a type of shield volcano) represent one important endmember of a variety of volcanic edifices occurring across the volcanic plains on the Moon, whereas Ring‐Moat Dome Structures (RMDSs) are interpreted to reflect the thermodynamic behavior of plain‐forming mare flows during their emplacement and cooling.
