The Impact of Uncertainty on Forecasting the US Economy

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT This paper examines the predictive value of uncertainty measures for key macroeconomic indicators across multiple forecast horizons. We evaluate how different uncertainty proxies—economic policy uncertainty (EPU), VIX, geopolitical risk, and measures of macroeconomic and financial uncertainty—enhance forecast accuracy for industrial production,

OLGGA: The OptimaL Ground Grid Application [PDF]

open access: yes, 2016
: The grounding system in a substation is used to protect personnel and equipment. When there is fault current injected into the ground, a well-designed grounding system should disperse the fault current into the ground in order to limit the touch ...

Knowledge sourcing, geopolitics, and FDI: An empirical analysis on the US green and digital sectors

open access: yesGlobal Strategy Journal, EarlyView.
Abstract Research Summary This paper examines how foreign direct investment (FDI) shapes firms' sourcing of knowledge in the digital and green domains under rising geopolitical frictions. We assemble a firm–country dyadic panel (2013–2020) linking US patent backward citations to firms' FDI, enriched with bilateral geopolitical distance and host‐country

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

open access: yesOikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Internal Permafrost Structure of Geomorphologically Distinct Palsas in Northern Sweden Revealed by Quasi‐3D ERT

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...

Tunable Surface Chemistry of Molten Salt Derived MXenes for Data‐Driven Electrochemical Materials Discovery

open access: yesSmall, EarlyView.
The surface chemistries of MXenes have been largely broadened by Lewis acid melts through expanded compositional diversity and functionalization routes. Such complexity makes data‐driven approaches particularly suitable for accelerated functionality discovery. This review examines surface chemistry from synthetic history to structure‐activity relations,

Vision language models for bridge inspections: A review of applications in image‐based damage documentation

open access: yesStructural Concrete, EarlyView.
Abstract Automating bridge inspections requires more than detecting individual damage instances. It demands systems capable of describing, contextualizing, and interpreting damage in an inspection‐relevant manner. Conventional computer vision approaches, such as object detection and segmentation, primarily address visual recognition tasks and are ...

Determining Basin Geometry, Stability, and Flow Dynamics of Valley Glaciers with Ground-Penetrating Radar [PDF]

open access: yes, 2014
Mountain glaciers and ice caps (GICs) currently contribute ~20% to annual sea level rise. Most are temperate, therefore having the potential for rapid retreat from rising atmospheric temperatures.
