Summary: This study developed a generalized additive model (GAM) approach to fill the missing pixels of MODIS/Terra 8-day Land Surface Temperature (MODIS LST) daytime products with the ERA5 Land Skin Temperature (ERA5ST) dataset in a high-latitude Eurasian watershed. Comparison revealed differences between MODIS LST and ERA5ST, with GAM models explaining the discrepancies using satellite-extracted environmental variables. The gap-filled MODIS LST products provide continuous details useful for monitoring permafrost degradation in cold regions under global climate change scenarios.

Summary: Heat flux systems are commonly used to assess core body temperature, but there is a lack of validation for multiple systems. In this experiment, three commercially available heat flux systems were compared to rectal temperature. The results showed that Medisim's values were lower than rectal temperature, while 3M and Core did not differ much. Therefore, caution should be taken in interpreting heat flux sensor values as core body temperature estimates, and further research is needed to explain the physiological significance of the generated temperature values.

Summary: This study aimed to compare the physiological and perceptual parameters related to cold-induced vasodilation (CIVD) in the fingers and toes of individuals with paraplegia and able-bodied individuals. By immersing the hand and foot in cold water and exposing them to different ambient temperatures, the responses of 7 participants with paraplegia and 7 able-bodied individuals were observed. The results showed that the occurrence of CIVD in the fingers was similar between the two groups, but participants with paraplegia displayed a higher frequency of CIVD in their toes under different conditions compared to able-bodied individuals.

Summary: In recent years, extremely cold events have been frequent globally, posing a serious threat to human health and safety. A study was conducted to investigate the physiological responses and thermal sensation of humans in extreme cold environments. The results showed that the ear is the most sensitive to temperature changes and blood pressure increased significantly during cold exposure, while heart rate decreased. The establishment of a transition space can help alleviate the pressure stimulus of a large temperature difference, and there are functional correlations between local skin temperature and thermal perception.

Summary: This study aimed to assess the factors associated with continued cooling duration of core temperature (Tc) after prolonged outdoor cold-water swimming. A cohort study was conducted among swimmers participating in an outdoor cold-water swim during qualifying for the English Channel Swim. Results showed that increased body mass index (BMI) and fat mass were associated with longer continued cooling duration, and the rate of Tc drop during swimming was negatively correlated with the rate of rewarming.

Summary: This study aimed to investigate the associations between daily averages and variations in ambient relative humidity (RH), temperature, PM2.5, and the severity of obstructive sleep apnea (OSA). A case-control study was conducted with 8628 subjects, and the results showed that the mean PM2.5 and RH were positively associated with the apnea-hypopnea index (AHI) in OSA patients, while the variation in RH was negatively associated with AHI. Reducing exposure to high ambient RH and PM2.5 levels may have protective effects on the AHI in OSA patients.

Summary: This study explores a transmission scheme for free-floating motes based on infrared, which reduces wireless data rate and system power consumption through pulse-interval modulation (PIM) communication. The results show that PIM has strong neural information transmission capability and matches the performance of traditional wired systems in real-time closed-loop BMI tests. Additionally, the PIM communication scheme is feasible in terms of power and enables high-channel-count high-performance BMIs.

Summary: The role of peripheral biomarkers in executive performance following acute aerobic and resistance exercise was explored in this study. The findings suggest that these biomarkers do not directly contribute to the reduction in reaction time following exercise, but a greater increase in noradrenaline may be associated with a decrease in accuracy after acute resistance exercise.

Summary: This paper presents a methodology for mapping and prioritizing research and innovation needs in a multi-disciplinary field. The methodology is applied to the field of Arctic maritime safety and security to guide a European Union funded research project. The methodology involves creating a hierarchy of needs through stakeholder workshops, literature review, and questionnaires, and then seeking stakeholder opinion to determine the importance and challenge level of each sub-need. A goal programming knapsack model is used to select priority needs based on overall importance, balance between topics, and balance between long-term research and short-term implementation needs.

Summary: When exposed to uncomfortable ambient temperatures, human behavioral responses are more effective than autonomic responses at regulating body temperature. These behavioral responses are influenced by an individual's perception of the thermal environment, which includes visual information. This review analyzes existing literature on the impact of visual environment manipulation on thermal perception, identifying frameworks, research rationales, and potential mechanisms. Out of 31 included experiments with 1392 participants, 80% reported a difference in thermal perception after manipulating the visual environment, suggesting the importance of visual cues in thermal perception.

Summary: Whole-body cryotherapy is a non-pharmacological treatment that influences inflammatory events and has various benefits, such as improved sleep quality, faster neuromuscular recovery, and chronic pain relief. It may also have positive effects on mental health and cognitive functions. There have been concerns about its safety, but these concerns are often based on misunderstandings regarding the differences between whole-body cryotherapy and partial-body cryotherapy. This article reviews the literature and concludes that the safety risks associated with whole-body cryotherapy are within acceptable limits and can be prevented by following existing recommendations and guidelines.
