Multistable Composite Laminate Grids as a Design Tool for Soft Reconfigurable Multirotors

Advanced Intelligent Systems, EarlyView.
Flexible, lightweight, stable: the reconfigurable multirotor combines stable flight in multiple shapes with low‐energy reconfiguration. Utilizing optimized multistable composites, it achieves self‐locking in open and folded configurations, cutting width‐span by 48% and allowing for safe gap traversal.

N and P constrain C in ecosystems under climate change: Role of nutrient redistribution, accumulation, and stoichiometry

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract We use the Multiple Element Limitation (MEL) model to examine responses of 12 ecosystems to elevated carbon dioxide (CO2), warming, and 20% decreases or increases in precipitation. Ecosystems respond synergistically to elevated CO2, warming, and decreased precipitation combined because higher water‐use efficiency with elevated CO2 and higher ...

Decision-tree decoders for general quantum LDPC codes [PDF]

arXiv
We introduce Decision Tree Decoders (DTDs), which rely only on the sparsity of the binary check matrix, making them broadly applicable for decoding any quantum low-density parity-check (qLDPC) code and fault-tolerant quantum circuits. DTDs construct corrections incrementally by adding faults one-by-one, forming a path through a Decision Tree (DT). Each

PairTilt: Design and Control of an Active Tilt‐Rotor Quadcopter for Improved Efficiency and Agility

Advanced Intelligent Systems, EarlyView.
PairTilt is an actuated tilt‐rotor unmanned aerial vehicle capable of active shape reconfiguration, balancing simplicity, efficiency, and agility. Its H‐shaped frame incorporates pairwise tiltable rotors, which reduce gyroscopic torque and decouple key dynamics, enhancing maneuverability and reducing drag.

Sapwood and heartwood are not isolated compartments: Consequences for isotope ecohydrology

Ecohydrology, Volume 15, Issue 8, December 2022., 2022
Abstract In most tree species, xylem consists of two different functional parts: sapwood and heartwood. While sapwood, as the flowpath for sap, has received more attention in isotope studies assessing water sources accessed by trees (e.g. soil water from different depths, groundwater, stream water or a mixture of these), much remains unknown about ...

Revealing Collaborative Effects of Binary Additives on Regulating Precursor Crystallization Toward Highly Efficient Perovskite Solar Cells

Angewandte Chemie, EarlyView.
The introduction of both PMAI and 2PACz into the precursor effectively cleaves edge‐shared Pb‐I octahedra to facilitate the transformation from PbI2 to PbI3− complexes as prenucleation clusters, and thus produces much larger colloidal particles with accelerated nucleation. Simultaneously, the crystallization in both spin‐coating and annealing processes

A Physics‐Informed Neural Network as a Digital Twin of Optically Turbid Media

Advanced Intelligent Systems, EarlyView.
In this work, a physics‐informed neural network is presented as a digital twin for modeling and studying optically turbid media without requiring reference light. The model learns and integrates complex wavefront modulation behavior, ensuring robustness without explicit calibration.

The green side of social innovation: Using sustainable development goals to classify environmental impacts of rural grassroots initiatives

Environmental Policy and Governance, Volume 32, Issue 6, Page 459-477, December 2022., 2022
Abstract Social innovations are grassroots processes aiming to achieve impacts beyond an individual level and towards a broader societal good. The environmental dimension of impacts refers to any direct change to the environment resulting from social innovation activities, products, or services, which are not addressed by pre‐existing systems.
