A round-trip ticket: the importance of release processes for in-stream nutrient spiraling [PDF]

, 2016
Most nutrient-spiraling studies have focused on estimates of gross uptake (Ugross), which show that streams take up dissolved inorganic nutrients very efficiently. However, studies based on estimates of net uptake (Unet) emphasize that streams tend to be

SeisDetNet: Artificial neural network for seismic event detection. Part 1: Architecture

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле
An artificial neural network, SeisDetNet, has been developed for distinguishing seismic events from seismic noise based on waveform records. The international STEAD database, which contains minute-long records of local earthquakes and seismic noise, was ...

Sensitivity analysis and parameter estimation for distributed hydrological modeling: potential of variational methods [PDF]

, 2009
Variational methods are widely used for the analysis and control of computationally intensive spatially distributed systems. In particular, the adjoint state method enables a very efficient calculation of the derivatives of an objective function ...

BiFormer Attention‐Guided Multiscale Fusion Mask2former Networks for Fish Abnormal Behavior Recognition and Segmentation

Aquaculture Research, Volume 2024, Issue 1, 2024.
To address the issues of accurately identifying and tracking individual fish abnormal behaviors and poor adaptability in the aquaculture field, this paper proposes a Mask2former model combined with a bidirectional routing attention mechanism (BiFormer) and a multiscale dilated attention (MSDA) module for fish abnormal behavior recognition and ...

Disturbed small-world networks and neurocognitive function in frontal lobe low-grade glioma patients.

PLoS ONE, 2014
BackgroundBrain tumor patients often associated with losses of the small-world configuration and neurocognitive functions before operations. However, few studies were performed on the impairments of frontal lobe low-grade gliomas (LGG) after tumor ...
