In this research, we present an enhanced human activity recognition (HAR) framework using advanced machine learning models incorporating temporal dynamics, leveraging multimodal sensor data. Data from wearable wristbands and real-time location systems (RTLS) were used to detect human activities within a home environment. A key advancement is the development of a spatiotemporal machine learning model combining convolutional neural networks (CNN), bidirectional long short-term memory (BiLSTM), and neural structured learning (NSL), which significantly surpasses traditional machine learning baseline models like RF, SVM.

Continuous and accurate heart rate monitoring is pivotal for the early detection of cardiovascular conditions. Traditional heart rate sensing methods, such as the use of adhesive electrocardiogram (ECG) electrodes, often fall short in terms of comfort and convenience for everyday wear and continuous monitoring. Ballistocardiography (BCG), a non-invasive alternative, offers a promising solution by measuring the body's mechanical reactions to the ejected blood by the heart during cardiac cycles.

Investigating erosion and river sediment yield in high-mountain areas is crucial for understanding landscape and biogeochemical responses to environmental change. We compile data on contemporary fluvial suspended sediment yield (SSY) and 12 environmental proxies from 151 rivers in High Mountain Asia surrounding the Tibetan Plateau. We demonstrate that glaciers exert a first-order control on fluvial SSYs, with high precipitation nonlinearly amplifying their role, especially in high-glacier cover basins.

This research assesses the adaptive capacity of farmers in the Vietnamese Mekong Delta's floodplains (VMD) with respect to hydrological changes. Currently, climate change and socio-economic developments induce extreme- and diminishing floods, which in turn increase farmers' vulnerability. This research assesses farmers' adaptive capacity to hydrological changes using two prevalent farming systems: high dykes featuring triple-crop rice farming and low dykes where fields are left fallow during the flood season.

Article Synopsis
  • This paper analyzes the 2011 Great Flood in central Thailand, focusing on whether the flood control operations at upstream dams could have alleviated downstream flood damage.
  • The study uses numerical modeling to propose that earlier water releases from the Bhumibol and Sirikit dams, based on better forecasting, could have mitigated flooding, finding that changing operation schemes might reduce flood depth but only minimally impact area inundation, with a maximum reduction of 3.68%.
  • The findings suggest limited effectiveness of these dams during the crisis and highlight the importance of improving local rainfall management, while also discussing lessons learned for better flood preparedness in future events in Thailand and beyond.
