In this letter, a temperature sensor based on fiber ring laser with reflective Sagnac loop is proposed. The inserted into the through download optical used as filter and sensing head to supply high sensitivity. As varies, transmission spectrum of changes, leading shift emission wavelength laser. We obtain system sensitivity 1.739 nm/°C, narrow 3-dB bandwidth less than 0.05 nm, signal-to-noise ratio ~50 dB. Moreover, it convenient achieve remote by changing length fiber.
Current achievements on electrochemical monitoring of cells are often gained two-dimensional (2D) substrates, which fail in mimicking the cellular environments and accurately reproducing functions within a three-dimensional (3D) tissue. In this regard, 3D scaffold concurrently integrated with function cell culture sensing is conceivably promising platform to monitor real time under their vivo-like microenvironments. However, it particularly challenging construct such multifunctional...
Abstract Objective Current practice of breaking bad news in China involves disclosure information first to family members who then decide whether the patient should receive this information. Recently, however, patients' right be informed has been regulated by law. This represents a dilemma for oncologists now have balance traditional with new legal requirements. A communication skills training (CST) was developed Chinese practice. It addresses issue and may help participants find individual...
An interleaved shared-aperture dual-band dual-polarized base station array antenna is proposed in this article. The lower-band (LB) element realized by using a multiple folded-dipole (MFDA) and four parasitic loops. To interpret the working principle of MFDA, double (DFDA) firstly analyzed transmission line (TL) model. Then, combining two bended DFDAs introducing loops, low cross-band scattering LB with high out-of-band rejection level 16 dB obtained to cover 2.3–2.7 GHz. higher-band (HB)...
A single-frequency fiber laser operating at 1950 nm has been demonstrated in an all-fiber distributed Bragg reflection cavity by using a 1.9 cm commercially available thulium-doped silica fiber, for the first time, to best of our knowledge. The was pumped 793 single-mode diode and had threshold pump power 75 mW. maximum output single longitudinal mode 18 mW slope efficiency with respect launched 11%. Moreover, linewidth relative intensity noise different have measured analyzed.
RIPK3 mediates cell death and regulates inflammatory responses. Although genetic studies have suggested that RIPK3-MLKL-mediated necroptosis leads to embryonic lethality in Fadd or Caspase-8-deficient mice, the exact mechanisms are not fully understood. Here, we generated Ripk3 mutant mice by altering kinase domain (Ripk3Δ/Δ mice), thus abolishing its activity. Ripk3Δ/Δ cells were resistant stimulation vitro, protected from necroptotic diseases. mutation rescued Fadd−/− embryos, died within...
A novel Gysel power divider based on patch type structure is presented in this paper.The proposed possesses broad bandwidth, small physical occupation and arbitrary division.More than 30% bandwidth enhancement achieved the -15 dB input return loss criteria, while 55% size reduction realized compared with conventional divider.What's more, flat dividing obtained design without using additional transmission line sections.Based structure, a procedure of dividers unequal division ratios provided...
With great economic value and practical value, the road crack detection is critical for rehabilitation. In this paper, an improved Otsu threshold method based on gray histogram proposed. By modifying probability weighting factor of histogram, proposed improves accuracy target extraction, avoids problem prominent peaks, solves image processing various types. The experiment results show that not only has good consistency in detecting cracks different pavements, but also fast calculation speed.
Previous studies have firmly demonstrated that wogonin, a naturally occurring monoflavonoid extracted from the root of Chinese herb medicine Scutellaria baicalensis , could effectively inhibit proliferation several cancer cell lines. However, little is known about effect wogonin on differentiation induction leukemic cells. Here we investigate potential role in and NB4, human promyelocytic leukemia line derived patient with acute leukemia. Our results indicated significantly suppressed...
We demonstrate a high-resolution temperature sensor based on optical heterodyne spectroscopy technology by virtue of the narrow linewidth characteristic single-frequency fiber laser.

In this paper, we propose and demonstrate a compact dual-parameter sensor for magnetic field intensity temperature based on the singlemode no-core fiber. The fiber (NCF) is coated with fluid to detect simultaneously. fundamental mode light launched from (SMF) will be decomposed into high-order modes lights in NCF, then, finally interfere exit SMF. Because different interference dips have sensitivities temperature, cross sensitivity of can effectively eliminated by monitoring two discrete...
