Ecosphere, 2021 Ecosystem process models can be used to predict forest response to disturbances at a range of scales. Selection of the spatial class of model should depend on the scale of the research or management question, and model type should depend on the ecosystem

, 2020 Disturbance observer is an inner-loop output-feedback controller whose role is to reject external disturbances and to make the outer-loop baseline controller robust against plant's uncertainties. Therefore, the closed-loop system with the DOB approximates the nominal closed-loop by the baseline controller and the nominal plant model with no ...

Disturbance-Disturbance uncertainty relation: The statistical distinguishability of quantum states determines disturbance [PDF]
Scientific Reports, 2018 AbstractThe Heisenberg uncertainty principle, which underlies many quantum key features, is under close scrutiny regarding its applicability to new scenarios. Using both the Bell-Kochen-Specker theorem establishing that observables do not have predetermined values before measurements and the measurement postulate of quantum mechanics, we propose that ...

VERTEBRAL PAIN SYNDROMES IN CHILDREN: ALGORITHMS OF THERAPY DEPENDING ON AGE
Alʹmanah Kliničeskoj Mediciny, 2016 Background: Publications on the problem of dorsalgia in children are scarce. Inadequate treatment of back pain in children and adolescents promotes the disease progression and contributes to high prevalence of this syndrome in adult population.Aim: To ...

Increased winter soil temperature variability enhances nitrogen cycling and soil biotic activity in temperate heathland and grassland mesocosms [PDF]
Biogeosciences, 2014 Winter air temperatures are projected to increase in the temperate zone, whereas snow cover is projected to decrease, leading to increased soil temperature variability, and potentially to changes in nutrient cycling. Here, we experimentally evaluated the

On 'spot' evolution under an adverse pressure gradient [PDF]
, 2001 The unsteady travelling 'spots' or spot-like disturbances are produced, in an otherwise planar boundary layer, by an initial impulse/blip, from wall forcing or from nearby external forcing. Theory and computations are described for the evolving spot-like

Increased tolerance to humans among disturbed wildlife. [PDF]
, 2015 Human disturbance drives the decline of many species, both directly and indirectly. Nonetheless, some species do particularly well around humans. One mechanism that may explain coexistence is the degree to which a species tolerates human disturbance ...

LiDAR Voxel-Size Optimization for Canopy Gap Estimation
Remote Sensing, 2022 Terrestrial laser scanning of forest structure is used increasingly in place of traditional technologies; however, deriving physical parameters from point clouds remains challenging because LiDAR returns do not have defined areas or volumes.
