Objective: To investigate the risk perception of heat wave, and further explore its related factors in Guangdong province.
Methods: A total of 2183 adults were selected by a multi-stage sampling method in Guangdong province. Each subject was interviewed in their home with a structured questionnaire by a well trained investigator from September to November, 2010. The questionnaire contained socio-demographic characteristics, heat wave related knowledge, risk perception of heat wave, etc. Chi-square test and multivariate logistic regression were employed in this study.
Results: The average age of total 2183 participants was (39.31 ± 14.16) years, among which 53.37% (1165/2183) were males, and 48.74% (1064/2183) were selected from urban. About 38.11% (832/2183) of participants heard about heat wave, and 38.52% (841/2183) of subjects thought the heat wave had higher impact on their health (risk perception score of heat wave ≥ 5 points). About 81.91% (1788/2183) of all participants thought the weather in most recent years was hotter than several years ago. Among these people, 30.48% (545/1788) thought the main reason of weather becoming hotter was due to emission of carbon dioxide, and 26.51% (474/1788) thought it was due to air pollution. Results from the multivariate logistic regression showed that the risk perception score of heat wave were higher in subjects with higher education (OR = 2.16, 95%CI: 1.41 - 3.30), from urban(OR = 1.37, 95%CI: 1.10 - 1.72), with higher score of trust(OR = 1.08, 95%CI: 1.01 - 1.14) and participants with higher score of heat wave related knowledge (OR = 1.39, 95%CI: 1.27 - 1.52). Furthermore, compared to hierarchist, egalitarian (OR = 1.73, 95%CI: 1.30 - 2.29), individualist (OR = 1.93, 95%CI: 1.41 - 2.65) and fatalist (OR = 1.80, 95%CI: 1.41 - 2.29) also had higher risk perception score of heat wave.
Conclusion: There is a lack of knowledge and risk perception to heat wave among the residents in Guangdong province. Risk perception of heat wave was higher in people who were from urban, had higher level of trust on government, experts and media, had higher health-related knowledge score, and non-hierarchists.

In laser safety eyewear, due to the lack of complete blocking of ultraviolet and infrared rays, we proposed a structure based on one-dimensional multilayer composed of several layers of silicon dioxide and zirconium dioxide materials alternately behind polycarbonate lens. It is find out that the acceptance angle range to the photonic crystal is 0 to 39°. This incident angle range corresponds to the band gap of the photonic crystal.

Intensifying the severity of electromagnetic (EM) pollution in the environment represents a significant threat to human health and results in considerable energy wastage. Here, we provide a strategy for electricity generation from heat generated by electromagnetic wave radiation captured from the surrounding environment that can reduce the level of electromagnetic pollution while alleviating the energy crisis. We prepared a porous, elastomeric, and lightweight BiTe/carbon aerogel (CN@BiTe) by a simple strategy of induced in situ growth of BiTe nanosheets with three-dimensional (3D) carbon structure, realizing the coupling of electromagnetic wave absorption (EMA) and thermoelectric (TE) properties.

The coherent spin waves, magnons, can propagate without accompanying charge transports and Joule heat dissipation. Room-temperature and long-distance spin waves propagating within nanoscale spin channels are considered promising for integrated magnonic applications, but experimentally challenging. Here we report that long-distance propagation of chiral magnonic edge states can be achieved at room temperature in manganite thin films with long, antiferromagnetically coupled spin spirals (millimetre length) and low magnetic Gilbert damping (~3.

Tissue factor (TF) is a cell surface protein that plays a role in blood clotting but is also commonly expressed in many cancers. Recent research implicated TF in cancer proliferation, metastasis, angiogenesis, and immune escape. Therefore, TF can be considered a viable therapeutic target against cancer.

Strong background interference signals from normal tissues have significantly compromised the sensitive fluorescence imaging of early disease tissues with exogenous probes in vivo, particularly for sensitive fluorescence imaging of early liver disease due to the liver's significant uptake and accumulation of exogenous nanoprobes, coupled with high tissue autofluorescence and deep tissue depth. As a proof-of-concept study, we herein report a near-infrared-II (NIR-II, 1.0-1.
