The effects of bark beetle-fire disturbance interactions on post-disturbance forest regeneration

, 2015
Disturbances in forested ecosystems create ecological legacies that can affect future disturbances and these disturbance interactions influence post-disturbance establishment. In addition, disturbances can become compounded and cause drastic ecosystem changes including decreased post-disturbance establishment, regeneration of unexpected species ...

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Holocene fire disturbance in the boreal forest of central Sweden

Boreas, 2013
Holocene fire disturbance and vegetation history were reconstructed using macroscopic charcoal and pollen accumulation rates from two lake sediment records (Holtjärnen and Klotjärnen) collected in the boreal forest of central Sweden. The records were used to examine the potential drivers associated with changes in fire regime.

Holocene plant diversity in Southern Sweden: climate, fire, land-use synergy and forest conservation

Frontiers in Ecology and Evolution
High-resolution pollen and charcoal records from two bogs—Stavsåkra in the hemiboreal zone and Storasjö in the boreal zone of central Småland, southern Sweden—were used to reconstruct Holocene plant diversity and to disentangle the relative impacts of ...

Freeform Light Routing in Nearly‐Hyperuniform Slabs: Toward a General‐Purpose Design Platform for Integrated Photonics

Advanced Optical Materials, EarlyView.
Nearly hyperuniform disordered photonic slabs guide light along prescribed freeform pathways without relying on lattice symmetry. A pathway‐first design embeds curved channels within a photonic bandgap hyperuniform network, maintaining high transmission through freeform bends.

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Effects of Forest Fire on Non-Structural Carbohydrates and Carbon, Nitrogen, and Phosphorus of Pinus yunnanensis

Plants
Fire is a crucial ecological factor, however, the organ-level effects of wildfire on plant non-structural carbohydrates (NSC) and stoichiometric characteristics are poorly understood. We studied the effects of fire on sugar, starch, carbon (C), nitrogen (
