Summary: In this project, a smartphone app was used to track the mood, sleep, and activity levels of outpatients with bipolar disorder. The results showed correlations between mood, sleep, and activity levels in different time frames, consistent with previous studies. The association between mood and future activity level was found to be particularly significant.

Summary: Recently, IQRF has emerged as a promising technology for IoT due to its ability to support short- and medium-range low-power communications. However, there is a lack of research on propagation modelling for IQRF network deployment in urban environments. This study proposes an empirical path loss model for the deployment of IQRF networks in a peer-to-peer configured system operating in the 868 MHz band. Extensive measurement campaigns are conducted to evaluate the prediction accuracy of well-known empirical path loss models, and the effects of different antennas on IQRF transceivers' performance are also examined. The findings of this study can provide useful insights for researchers interested in developing IoT-based smart city applications.

Summary: To ensure the safety of citizens and facilities during a disaster, obtaining timely information around the disaster site is crucial. This study introduces an algorithm that uses a single smartphone image to estimate the absolute locations of non-stationary objects, such as vehicles. By combining theories of photogrammetry, coordinate transformation, object detection, and depth estimation, the algorithm calculates and displays the target objects' locations in a geographic coordinate system, enabling quick decision-making. The algorithm was compared to ground reference points and achieved an average absolute location error of 4.118 m.

Summary: This study investigated the multi-scale effects of indicators, including urban shadows, on urban thermal environment research (UTE) during mid-day hours. Results showed that temperature variations mid-day were better explained by smaller scales of landscape heterogeneity and larger scales of landscape consistency under shadow conditions, while temperature under direct sunlight was primarily influenced by larger scales. Trees significantly reduced temperature, while building area and height were significantly correlated with temperature. These findings provide crucial reference data for micro-scale UTE investigations during mid-day hours and offer new strategies for urban planning and design.

Summary: The study investigates the effects of urbanization on bird reproduction and related regulatory molecules. Results show that urban birds exhibit higher levels of corticosterone during the stimulatory phase, and a delay in testicular growth, possibly due to lower T3 levels and reduced transcription of Dio2 and GnRH mRNA in urban birds.

Summary: During the high-speed urbanization in Chinese cities, the effects of urban traditional district renewal on urban microclimate and residential living conditions have not been well studied. This study proposes two renewal plans for traditional districts in Xi'an, which aim to improve living convenience and thermal environment by adding vegetation in open spaces or combining vegetation with building redevelopment. The effects of these plans on thermal environment are evaluated using ENVI-met simulation, providing a method for environmental evaluation and sustainable urban planning in historical districts.

Summary: This study conducted field measurements on the thermal environment within gers heated by coal stoves. The results showed diverse daily fluctuations of indoor temperature influenced by the unstable heating power of stoves. The occasional outliers in indoor air temperature beyond the comfort range contrasted with the operative temperature, which was mostly within the comfort range due to the direct radiation of stoves.

Summary: In this study, a smartphone-based spectrometer is used for dynamic analysis of the optical response of an electro-optically modulated lossy-mode resonance (LMR) optical fiber sensor. By coating a section of the fiber core with a fluorine-doped tin oxide (FTO) thin film, the LMR is achieved and the FTO is used as an electrochemical electrode. The smartphone-based spectrometer is capable of dynamically measuring the change in charge carriers in the FTO when an electrical potential is applied to the sensor, with a time resolution below 0.5 s. Furthermore, the system demonstrates high sensitivity in detecting low concentrations of GFP, making it suitable for various biosensing applications.

Summary: Urban forest, especially tree canopy, plays a crucial role in improving urban climatic environment and residents' living quality. This study in Luoping County, China, explores the relationship between tree canopy and thermal environment, finding that increasing the area and perimeter of tree canopy coverage can effectively cool down the urban area.

Summary: YDigital hemispherical photography (DHP) is used for measuring radiative environment, estimating sky view factors (SVF) in urban areas, and leaf area index (LAI) in forests. Limitation lies in difficulty to distinguish trees from buildings. Method successfully classifies pixels into sky, green and woody plant elements, and buildings for various applications.
