Topography constrains the climatic response of treeline migration in Taiwan's subalpine forests
Ecography, EarlyView.Treelines are moving upslope, but the rates and drivers differ among different regions, globally. Many studies have examined the relationship between treeline movement and climate change, particularly rising temperature, while the role of topographical factors has received much less attention, despite the longstanding recognition of its importance.

InfoMat, EarlyView.This work constructs a series of graphite anodes with systematically varied binder distribution, porosity, and electrode thickness to resolve the role of microstructural heterogeneity during fast charging. The digital twin framework reveals how phase‐level structural gradients govern Li plating, SEI formation, and diffusion‐induced stresses, providing ...

Strategic Change, EarlyView.ABSTRACT Research has often portrayed entrepreneurs in largely positive terms, reflecting their contributions to innovation, employment, and economic growth. At the same time, it is well recognized that entrepreneurial activity can also involve harmful and unethical behaviors, as evidenced by numerous cases of misconduct among business owners and ...

Strategic Change, EarlyView.ABSTRACT A key challenge in public procurement management is balancing equity and efficiency in government procurement. Based on longitudinal data on more than 120,000 US federal service and construction contracts awarded between 2008 and 2018 across over 500 federal agencies, we examine how agency‐level dynamic capabilities shape the performance of ...

Near Surface Geophysics, EarlyView.Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.
