    Series title Synthesis Lectures on Technology and Health,
    Abstract This book looks at how AgeTech can support the autonomy and independence of people as they grow older. The authors challenge readers to reflect on the concepts of autonomy and independence not as absolutes but as experiences situated within older adults’ social connections and environments. Eleven personas of people around the world provide the context for readers to consider the influence of culture and values on how we understand autonomy and independence and the potential role of technology-based supports. The global pandemic provides a backdrop for the unprecedentedly rapid adoption of AgeTech, such as information and communication technologies or mobile applications that benefit older adults. Each persona in the book demonstrates the opportunity for AgeTech to facilitate autonomy and independence in supporting one’s identity, decision making, advance care planning, self care, health management, economic and social participation, enjoyment and self fulfillment and mobility in the community. The book features AgeTech from around the world to provide examples of commercially available products as well as research and development within the field. Despite the promise of AgeTech, the book highlights the “digital divide,” where some older people experience inadequate access to technology due to their geographic location, socio-economic status, and age. This book is accessible and relevant to everyday readers. Older adults will recognize themselves or peers in the personas and may glean insight from the solutions. Care partners and service providers will identify with the challenges of the personas. AgeTech entrepreneurs, especially “seniorpreneurs,” will appreciate that their endeavours represent a growing trend. Researchers will be reminded that the most important research questions are those that will enhance the quality of life of older adults and their sense of autonomy and independence, or relational autonomy and interdependence.

    Abstract The cold‐chain information has characterized by the loss and dispersion according to the different collecting methods. The description for the quality decay factors of aquatic products can be defined as the multidimensional information. A series of nodes with multidimensional information are assembled to be hierarchies aiming at describing the environment conditions and locations in the supply chain. Each of the single hierarchy levels constitutes a sequence of node information in a network, which is applied as internal information analysis. The cross‐layer information structure is defined as “bridge” information which is able to record the information transmissions among every hierarchy from the point of view of the whole chain. The study has established a novel structured modeling to describe the cold chain of aquatic products based on a network‐hierarchy framework. An organized and sustainable transmission process can be built and recorded by the multidimensional attributes for the whole course of cold chain of aquatic products. In addition, seamless connections among every hierarchy are attainable by the environmental information records continuously to monitor the quality of aquatic products. The quality assessments and shelf life predictions are estimated properly as the risk control in order to monitor and trace the safety of aquatic products under the supply chain perspective.

    Abstract Background: Osteoporosis is a medical disorder that causes bone tissue to deteriorate and lose density, increasing the risk of fractures. Applying Neural Networks (NN) to analyze medical imaging data and detect the presence or severity of osteoporosis in patients is known as osteoporosis classification using Deep Learning (DL) algorithms. DL algorithms can extract relevant information from bone images and discover intricate patterns that could indicate osteoporosis.
    Objective: DCNN biases must be initialized carefully, much like their weights. Biases that are initialized incorrectly might affect the network's learning dynamics and hinder the model's ability to converge to an ideal solution. In this research, Deep Convolutional Neural Networks (DCNNs) are used, which have several benefits over conventional ML techniques for image processing.
    Method: One of the key benefits of DCNNs is the ability to automatically Feature Extraction (FE) from raw data. Feature learning is a time-consuming procedure in conventional ML algorithms. During the training phase of DCNNs, the network learns to recognize relevant characteristics straight from the data. The Squirrel Search Algorithm (SSA) makes use of a combination of Local Search (LS) and Random Search (RS) techniques that are inspired by the foraging habits of squirrels.
    Results: The method made it possible to efficiently explore the search space to find prospective values while using promising areas to refine and improve the solutions. Effectively recognizing optimum or nearly optimal solutions depends on balancing exploration and exploitation. The weight in the DCNN is optimized with the help of SSA, which enhances the performance of the classification.
    Conclusion: The comparative analysis with state-of-the-art techniques shows that the proposed SSA-based DCNN is highly accurate, with 96.57% accuracy.

    Abstract The COVID-19 pandemic posed an unprecedented threat to the mental health of youth due to its attendant, drastic changes in everyday life brought about by restrictions such as social distancing and the cancelation of in-person classes. Although numerous articles have discussed the impact of the pandemic on youths' mental health, most of them have been opinion pieces. This study used state-wide empirical data to quantify the direct and indirect effect of the pandemic on the mental health of confined youth, a vulnerable social group that is rarely represented in school survey data. Group comparisons of youth who entered juvenile justice facilities during pandemic and non-pandemic times were also conducted. Findings revealed that youth who entered residential facilities during the pandemic due to criminal offenses had higher rates of prior mental health problems and victimization. With major confounders controlled, multivariate regression results showed that the impact of the pandemic on confined youths' mental health is indirect: it conditioned the effect of underage drinking on the youths' mental health. Youth who were admitted into facilities during the pandemic were more likely to experience mental health problems than their peers who entered facilities during non-pandemic times. Implications for policymaking are discussed.

    Abstract Permafrost has long been listed as a terrestrial Essential Climate Variable (ECV) by the Global Climate Observing System (GSOS). According to the GSOS ECVs guidelines and requirements as released in 2022, three ECV products are associated with permafrost, including permafrost temperature, active layer thickness, and rock glacier velocity. Since permafrost is purely defined by the subsurface temperature, many of its changes occurring underground are mainly observed by borehole measurements but with limited spatial coverage. This paper reviews the applications and potential of geodetic methods to generate ECV products of active layer thickness and rock glacier velocity. Leveling, InSAR, and GNSS Interferometric Reflectometry measure seasonal, cyclic thaw subsidence and frost heave. A few retrieval algorithms have been developed to take the geodetic measurements of elevation changes as the input to indirectly estimate active layer thickness and have achieved moderate success in a few case studies. Substantial improvements, especially incorporation with frozen ground hydro-thermal models and remote sensing products of soil moisture and ground surface temperature, are warranted to improve the accuracy and generalizability of geodetic methods for generating reliable active layer thickness. Despite being just added by GSOS in 2022 as a new ECV product, rock glacier velocity has been routinely measured using various geodetic methods including theodolites, total stations, GNSS, laser scanning, and InSAR for years to decades. The geodesy community should be actively involved to provide inputs to the International Permafrost Association to standardize the measurement protocols for monitoring changes of rock glacier velocities around the globe.

    Abstract Aerosol effects on convective clouds remain an important open-ended question in climate research. This paper reports on the climatological effects of anthropogenic aerosols on the convections during Mei-yu season by means of long-term simulations with the Weather Research and Forecasting with Chemistry (WRF/Chem) model. Sensitivity experiments indicate that increased aerosols reduce the total rainfall and convection occurrences by 9.00% and 7.17% over the Yangtze–Huai River Valley during Mei-yu season due to the suppression of shallow convections with cloud geometrical thickness (CGT) less than 4 km. Aerosol radiation effect plays a dominant role in shallow convections suppression by cooling the surface air and increasing regional atmospheric stability. On the contrary, deep convections are invigorated under polluted conditions with a stronger updraft and more latent heating release, which can be explained by the interactions between aerosol-induced microphysical effects and the dynamical response. Due to the shorter distances that the downdrafts accelerate to the surface in shallow convections, the interaction between dynamics and microphysics is reduced comparing to the deep convections, leading to suppression of shallow convections at high aerosols. In addition, relative humidity which controls the balance between the net generation and loss of condensate mass is an important meteorological factor in regulating the net influence of aerosols on convections. These findings provide us insight into the competing mechanism between aerosol radiative and microphysical effects on convections during Mei-yu season, which can aid in better parameterizing aerosol effects in climate models.

    Abstract Solar active regions (ARs) that produce large solar eruptions usually own compact, highly-sheared polarity inversion lines (PILs). A scenario named as “collisional-shearing” is proposed to explain the formation of this type of PILs and the subsequent eruptions, stressing the role of collision and shearing induced by the relative motions of different bipoles in their emergence. However, if not considering the evolution stage of the ARs, about one third of the observed ARs that produce large solar eruptions govern a spot-spot type, i.e., an overall bipolar configuration. In this work, we studied the full evolution of an emerging, spot-spot type, eruption-producing AR, to explore the possible evolution gap between “collisional shearing” and the formation of the spot-spot type AR. It was found that the AR was formed through three bipoles emerged sequentially. The parallel arrangement of the bipoles made the AR exhibiting an overall bipolar configuration. In the fast emergence phase, the shearing gradually occurred due to the polarities’ imbalanced proper motions, but no significant collision occurred due to the bipoles’ parallel arrangement. Nor did the large eruption occur. After the fast emergence, one positive polarity started to decay, leading to collision to a non-conjugated negative polarity. A huge hot channel was formed through precursor flarings that initiated from the collision region. It erupted later, inducing an M7.3-class flare and a CME. The results suggest that even in the spot-spot type AR, the collision and shearing may also occur between non-conjugated polarities, playing a major role in producing the large eruptions.

    Abstract Brain injury is the main factor affecting the development and prognosis of the nervous system in premature infants. Early diagnosis and treatment are of great significance in reducing mortality and disability and improving the prognosis of premature infants. Craniocerebral ultrasound has become an important medical imaging method for evaluating the brain structure of premature infants due to its advantages of being non-invasive, cheap, simple, and bedside dynamic monitoring since it was applied to neonatal clinical practice. This article reviews the application of brain ultrasound to common brain injuries in premature infants.
