Thermal structures of the Pacific lithosphere from magnetic anomaly inversion

Earth and Planetary Physics, 2018
Of the world's oceans, the Pacific has the most abundant distribution of seamount trails, oceanic plateaus and hot spots, and has the longest fracture zones.

Long vs. short: understanding the dynamics of persistent summer hot spells in Europe [PDF]

Weather and Climate Dynamics
The persistence of surface hot spells in Europe on subseasonal timescales can lead to significant socio-economic impacts. Here, we adopt a regional perspective to compare the dynamical features associated with long-lasting persistent (12–26 d) and short ...

Hot flow anomaly formation by magnetic deflection

Geophysical Research Letters, 1990
Hot Flow Anomalies (HFAs) are localized plasma structures observed in the solar wind and magnetosheath near the Earth's quasi‐parallel bow shock. We present 1‐D hybrid computer simulations illustrating a formation mechanism for HFAs in which the single, hot, ion population results from a spatial separation of two counterstreaming ion beams.

Wave activity inside hot flow anomaly cavities [PDF]

Journal of Geophysical Research: Space Physics, 2008
Low‐frequency wave properties inside two hot flow anomalies (HFAs) at different stages of evolution are, for the first time, studied applying the k‐filtering technique on multipoint measurements from the Cluster satellites. The observed wave activity in an HFA cavity in an early stage of its evolution was interpreted as the combination of inherent ...

New Insights into Crust and upper Mantle Structure in Guangdong Province, China and Its Geothermal Implications

Energies, 2021
Southeast Asia contains significant natural geothermal resources. However, the mechanism for generating geothermal anomalies by the crust–mantle structure still needs to define. In this study, we focused on Guangdong Province, China.

Global ULF waves generated by a hot flow anomaly [PDF]

Geophysical Research Letters, 2017
AbstractHot flow anomalies (HFAs), which are frequently observed near Earth's bow shock, are phenomena resulting from the interaction between interplanetary discontinuities and Earth's bow shock. Such transient phenomena upstream the bow shock can cause significant deformation of the bow shock and the magnetosphere, generating traveling convection ...

Active grid turbulence anomalies through the lens of physics informed neural networks

Results in Engineering
Active grids operated with random protocols are a standard way to generate large Reynolds number turbulence in wind and water tunnels. But anomalies in the decay and third-order scaling of active-grid turbulence have been reported.

Subduction to the lower mantle – a comparison between geodynamic and tomographic models [PDF]

Solid Earth, 2012
It is generally believed that subduction of lithospheric slabs is a major contribution to thermal heterogeneity in Earth's entire mantle and provides a main driving force for mantle flow.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
