Logging Residues of Low Harvest Intensity in Indonesian Forest Concession
Jurnal Ilmu Pertanian Indonesia, 2020 Forest harvesting of natural-forest production in Indonesia is carried out with a high felling intensity, thus has changed the forest biomass. Several studies have shown a strong correlation between harvesting intensity and the reduction of wood volume ...

Performance, Capability and Costs of Motor-Manual Tree Felling in Hyrcanian Hardwood Forest
Croatian Journal of Forest Engineering, 2013 Motor-manual tree felling is the most labor-intensive component of all harvesting operations and frequently represents a bottleneck in wood production. The study of motor-manual tree felling was carried out in two compartments in the Namkhaneh district ...

Industrial round-wood losses associated with motor-manual tree felling and bucking (Case study: Kheyrud forest, Iran) [PDF]
Iranian Journal of Wood and Paper Industries, 2015 Damage to the harvested log can occur during the felling, delimbing, bucking, skidding, piling, and hauling functions of wood harvesting. A field-based study was performed to determine the amount of industrial round-wood losses associated with most ...

Personalized Network‐Guided Neuromodulation Enhances Human Working Memory
Advanced Science, EarlyView.A personalized neuromodulation framework combining individualized functional brain network targeting with real‐time neural decoding is introduced. Using concurrent TMS–fMRI, participant‐specific stimulation targets and optimal frequencies are identified. Only optimal‐frequency stimulation improves working memory across sessions.

Advanced Science, EarlyView.ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...
