Amid growing global food security concerns and frequent armed conflicts, real-time monitoring of abandoned cropland is essential for strategic planning and crisis management. This study develops a method to map abandoned cropland accurately, crucial for maintaining the food supply chain and ecological balance. Utilizing Sentinel-1/2 satellite data, we employed multi-feature stacking and machine learning to create the ARCC10-IM (Abandoned and Reclaimed Cropland Classification at 10-meter resolution in Inner Mongolia) dataset, which tracks annual cropland activity. A novel temporal segmentation algorithm was developed to extract cropland abandonment and reclamation patterns annually, using sliding time windows over several years. This research differentiates cropland states-active cultivation, unstable fallowing, continuous abandonment, and reclamation-providing continuous, regional-scale maps with 10-meter resolution. ARCC10-IM is crucial for land planning, environmental monitoring, and agricultural management in arid areas like Inner Mongolia, enhancing decision-making and technology in land use tracking.

Nystagmus has various clinical manifestations, including downbeat, upbeat, and torsional types, each associated with distinct neurologic features. Current rehabilitative interventions focusing on fixation training and optical correction often fail to achieve complete resolution. When nystagmus coexists with fragile X-associated tremor/ataxia syndrome (FXTAS), functional impairments worsen, particularly affecting balance.

The dual passband of the filter not only exhibits ultra-high frequency selectivity but also allows for flexible and simultaneous tuning of the center frequency and interval of the passbands. In the proposed scheme, the core optical processor of the MPF consists of a dual-ring Brillouin laser resonator, which is composed of a 100-meter main fiber ring cascaded with a 10-meter secondary fiber ring.

Article Synopsis
- - This study created a high-resolution, daily gridded meteorological dataset (CDMet) for mainland China covering the years 2000 to 2020, useful for climate change research.
- - The dataset includes nine key meteorological variables, such as air temperature, precipitation, and wind speed, based on advanced interpolation methods combining thin-plate spline and random forest techniques.
- - Validation tests confirmed CDMet's accuracy and seasonal variability, making it suitable for applications in hydrology, agriculture, and ecology, and comparable to other existing datasets.

Aim: To evaluate whether serum metabolomics differ between ambulatory individuals with cerebral palsy (CP) compared with individuals with typical development and whether functional capacity is associated with metabolite abundance.
Method: Thirty-eight adolescents and young adults were enrolled (CP: n = 19; typical development: n = 19). After functional capacity testing (10-meter walk, sit-to-stand, and peak knee flexion/extension torques), blood was drawn.
