Multifunctional Textile Platform for Fiber Optic Wearable Temperature-Monitoring Application.

Wearable sensing technologies have been developed rapidly in the last decades for physiological and biomechanical signal monitoring. Much attention has been paid to functions of wearable applications, but comfort parameters have been overlooked. This research presents a developed fabric temperature sensor by adopting fiber Bragg grating (FBG) sensors and processing via a textile platform. This FBG-based quasi-distributed sensing system demonstrated a sensitivity of 10.61 ± 0.08 pm/°C with high stability in various temperature environments. No obvious wavelength shift occurred under the curvatures varying from 0 to 50.48 m-1 and in different integration methods with textiles. The temperature distribution monitored by the developed textile sensor in a complex environment with multiple heat sources was deduced using MATLAB to present a real-time dynamic temperature distribution in the wearing environment. This novel fabric temperature sensor shows high sensitivity, stability, and usability with comfort textile properties that are of great potential in wearable applications.

Controllable symmetry breaking solutions for a nonlocal Boussinesq system.

The generalized Boussinesq equation is a useful model to describe the water wave. In this paper, with the coupled Alice-Bob (AB) systems, the nonlocal Boussinesq system can be obtained via the parity and time reversal symmetry reduction. By introducing an extended Bäcklund transformation, the symmetry breaking rogue wave, symmetry breaking soliton and symmetry breaking breather solutions for a nonlocal Boussinesq system are obtained through the derived Hirota bilinear form. The residual symmetry and finite symmetry transformation of the nonlocal AB-Boussinesq system are also studied.

[Construction of eukaryotic plasmid expression Hsf4b and phosphorylation of Hsf4b by MAP kinase P38].

AIM: Ton construct eukaryotic plasmid expressing Hsf4B and to investigate Hsf4b is phosphorylated by MAP kinase P38: METHODS: The total RNA of human heart tissues were prepared. Hsf4b cDNA were then synthesized with RT-PCR. The PCR products were digested with Kpn I and EcoR I and subcloned into pcDNA3.0, pcDNA-Flag-Hsf4b was transfected into HEK293T cells. The expression of Hsf4b was testified with Western blotting. The interaction between Hsf4b and P38 was assayed by immunoprecipitation. In vivo pull down GST demonstrated that Hsf4B (196-493) could interact with P38, P38 phosphorylation of Hsf4b were testified with Kinase assay. RESULTS: We subcloned the human cDNA of Hsf4b into eukaryotic expression vectors pcDNA3 and PEBG, and Hsf4b was overexpressed in HEK293T cells. Further studies demonstrated that Hsf4b could interact with and phosphorylated by MAP kinase P38. CONCLUSION: Hsf4b could interact with and phosphorylated by MAP kinase P38. Our results will provide more evidence for understanding the signal regulation of Hsf4b transcription activity during lens development.
