Advanced Science, EarlyView.A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Mountainous areas and hillslopes on both Earth and Mars are actively being eroded by various sediment transport processes. On Earth, one of the dominant processes causing change on hillslopes are debris flows. These fast-moving masses of soil, rock and water carve deep valleys and transport sediment from mountain peaks to the valleys.

Dynamics of envelopes of planetary nebulae
The Astrophysical Journal, 1976 Section III deals with a phenomenon typical of much of interstellar space. When a gas is hot, velocity differences of the order of the sound speed are established. If the ionization later disappears and the gas cools, the same velocity gradients lead to strong gas compression.

Rainfall Shapes the Diversity of Soil Nitrogen‐Fixing Microorganisms Worldwide
Advanced Science, EarlyView.This study reveals the distinctive pattern and mechanism of rainfall driving the global biodiversity and biogeography of soil potential N‐fixing microorganisms, and constructs the theoretical framework. The results guide us on how to maintain ecosystem productivity under future climate changes (e.g., whether a specific region needs more N fertilizers ...

Dynamical circulation regimes in planetary (and exo-planetary) atmospheres
, 2017 In this thesis, we study the effect of diurnally- and seasonally-varying forcing on the global circulation of planetary atmospheres explored within a large parameter space. This work focusses on studying the spacial and spectral energy budgets across a large range of planetary parameters as well as the momentum transfer as a response to diurnal and ...

Advanced Science, EarlyView.AM symbiosis induces GhWAK13 to promote fungal colonization. GhNTF3 negatively regulates symbiosis by promoting SA biosynthesis. GhWAK13 sequesters GhNTF3 at the membrane, limiting its nuclear translocation and relieving SA‐mediated suppression. Under Verticillium stress, GhNTF3 enters the nucleus and interacts with GhJAZ6 to activate SA signaling ...
