Automatic Recognition Algorithm of Convergence Region Based on Relative Storm Radial Velocity Field

应用气象学报, 2021
An algorithm for automatically identifying the mid-altitude radial convergence from the storm-relative radial velocity field is proposed. The algorithm first identifies the positive-negative velocity segments in each radial direction on the single ...

Divergent Responses of Bacterial Communities to Permafrost Degradation and Their Associations With Carbon Across Vertical Profiles

Advanced Science, EarlyView.
Bacterial α‐diversity decreases, but stochasticity and community stability increase across the 15 m‐depth vertical profiles and along the degraded gradient within the active layer. The abundance and interaction of core taxa mainly control community stability in the active and permafrost layers, respectively.

Tools for agricultural drought detection in the frame of Drought Management Centre for Southeastern Europe – DMCSEE

Acta Agriculturae Slovenica, 2012
Numerous specialized indices have been proposed to assess drought severity, but the precise quantification of drought is a difficult challenge. The purpose of this paper is to evaluate two indices: the well known Standardized Precipitation Index (SPI ...

Water‐Efficient Smart Drip Irrigation Enabled by a Low‐Power and High‐Efficiency Flexible Electromagnetic Actuator

Advanced Science, EarlyView.
Water scarcity poses a critical threat to global food security. A low‐power, flexible electromagnetic actuator is presented for smart drip irrigation systems. The device achieves precise, wide‐range flow modulation (0.05–5.8 mL/min) in response to real‐time plant demands, reducing water consumption compared to conventional flood irrigation.

TOGR3, a Proteasome β4 Subunit, Orchestrates Sugar Homeostasis to Trade Off Growth and Thermotolerance in Rice

Advanced Science, EarlyView.
This study identifies a novel thermoregulatory mechanism in rice: TOGR3 partners with 26S proteasome subunits, including TT1, to drive thermoresponsive ubiquitin–proteasome activity, maintaining sugar homeostasis in stomatal regulation to balance growth and stress resistance.

Predicting sugar beet leaf area index: evaluating performance of double sigmoid functions under different irrigation and plant density scenarios

Scientific Reports
The leaf area index (LAI) dynamics in sugar beet follow a double sigmoidal curve, modeled as the subtraction of two sigmoid functions. In this study, we examined the accuracy of 15 different sigmoid functions in describing the sugar beet LAI variation ...
