title: How AI Alleviates Woes: The Impact of Chatbot Relational Cues on Emotional Interaction Experiences

description: The relationship between humans and AI has evolved into a phase of deep integration, with the latest generation of text-based chatbots increasingly serving as trusted companions for emotional support. Relational cues (features in chatbots designed to simulate human emotional and social behaviors) reflect the core characteristics of human social existence and play a crucial role in enhancing human-AI emotional interactions. This research employs a mixed-methods approach to explore how relational cues shape human-AI emotional interaction experiences. Study 1 selected common indicators of emotional interaction experience and used an experimental method (<i>n</i> = 196), which showed that relational cues significantly increased users’ emotional arousal, system usability, emotional attachment and human-AI trust. Moreover, mind perception exerted a negative moderating effect on the relationship between relational cues and pleasure, arousal, dominance, emotional attachment and usability. Furthermore, the efficacy of specific types of relational cues (particularly empathy) was stronger in extreme negative emotional events compared to moderate ones. Study 2 used an online survey method (<i>n</i> = 25) and further revealed that relational cues can improve mood, enhance perceived realism, foster intimacy, and elevate conversational quality. These improvements collectively contributed to enhancements in multifaceted emotional interaction experiences. It is worth noting that empathy cues exhibited the most positive effect in both studies. These findings highlight the beneficial role of relational cues in human-AI emotional interactions and their boundary conditions, providing a theoretical foundation for emotional agent design from the perspective of chatbot, users, and event.

title: Selfie WanD: Designing User-Defined Gestures for Selfie Stick Photography and Gesture Recognition Using a Smartphone’s Built-in IMU

description: This study explores the possibility of gestural interaction on selfie sticks. We conducted a gesture elicitation study (GES) for selfie stick photography with 20 participants to identify intuitive gestures under two conditions: one allowing both movement and touch of the selfie stick, and one allowing only gestures involving its movement. Based on these findings, we implemented a system using a smartphone's built-in IMU sensor and created a machine-learning model to recognize user-defined gestures in the movement-only condition. We collected data for ten gesture types through a user study (<i>N</i> = 10). The model was trained on data recorded in the standing condition and evaluated using leave-one-out cross-validation across participants, achieving a classification accuracy of 99.7%. Moreover, the model demonstrated robust performance under variations in user walking behavior, selfie stick length, and stick type, indicating the feasibility of gesture-based interaction for enhancing selfie stick photography.

title: 40-Year Volume Changes of West African Lakes Derived from SWOT and Optical Imagery

description: The datasets described below are published along with the article "40-Year Volume Changes of West African Lakes Derived from SWOT and Optical Imagery" (submitted to Water Resources Research) F. Girard, L. Kergoat, J. M. Silva Paiva, R. Yonaba, and M. Grippa For more information, you can contact: - Félix Girard (girard.felix2@gmail.com) - Manuela Grippa (manuela.grippa@utoulouse.fr) - Laurent Kergoat (laurent.kergoat@get.omp.eu) ########## Volume change time series (volume_change_time_series.csv): ########## Dataset (CSV) containing the 40-year volume change time series for 1363 different West African lakes included in the SWOT Prior Lake Database (PLD). For each different PLD ID, volume changes are referenced to the first acquisition of the time series. The columns correspond to: - pld_id: ID of the lake's PLD polygon - time: acquisition time of Landsat image - vol_change (km3): lake volume change between the present time and the previous one - sat_ls: Landsat satellite associated with the present acquisition (e.g. LT05 for Landsat-5) - tile_ls: ID of the Landsat tile associated with the present acquisition (e.g. 195_49) ########## Hypsometry dataset (lake_hypsometry.csv): ########## Dataset (CSV) containing hypsometry data (pairs of time-matched water surface area and elevation measurements) for 1363 different West African lakes included in the SWOT Prior Lake Database (PLD). For each different PLD ID, hypsometry data are sorted by ascending water surface_area. The columns correspond to: - pld_id: ID of the lake's PLD polygon - time_swot: acquisition time of SWOT measurement - time_ls: acquisition time of Landsat image - wse: SWOT-based lake water surface elevation - water_area: CNN/Landsat-based lake water surface area - tile_SWOT: ID of the SWOT tile (e.g. 432_126L) - tile_ls: ID of the Landsat tile (e.g. 195_49) ########## CNN/Landsat train and test polygons (cnn_landsat_train_polys.gpkg and cnn_landsat_test_polys.gpkg): ########## Two datasets (Geopackage) containing the polygons (EPSG:4326) used to train and test the CNN/Landsat model, respectively. Training dataset (763 polygons) spans different climates from southern Burkina Faso to Central Mali. Testing dataset (355 polygons) covers surface contexts in Niger, Mali, Burkina Faso, and Mauritania which have not been observed during the training of the model. The columns correspond to: - id: unique integer id - ls_image: name of the Landsat image associated with the polygon - geometry: coordinates of the polygon

title: Calcium Carbonate Constrains the Capacity and Saturation of Mineral-Associated Organic Carbon in Global Soils

description: Mineral-related organic carbon (MAOC) is the most stable and persistent component of soil organic carbon and the core of long-term carbon storage. However, the quantification of its capacity and saturation is insufficient on a global scale, especially in calcium-containing soils that cover large areas of the Earth's land. This study integrates regional soil sampling with a global dataset to systematically evaluate the limiting effect of calcium carbonate on the storage and saturation of MAOC. We utilized random forest machine learning models for both calcium-bearing and non-calcium-bearing soils to generate a global MAOC distribution map (0-30 cm), and revealed that although calcium-bearing soils cover nearly one-third of the global land area, they only account for 23% of the global MAOC reserves. Our findings highlight the role of calcium carbonate in carbon stabilization by restricting the mineral surface sites available for organic carbon retention. This makes a significant revision to the current global carbon model and provides a new understanding of the mechanism of soil carbon heterogeneity.
