Abstract:
The research considers the possibility of applying the forced «aging» method used for single-mode cable optical fibers in accordance with IEC 60793-2-50 to confirm the reliability of the PANDA PM Specialty optical fiber under long-term bending. A comparison of the results of PANDA PM Specialty optical fiber with isotropic optical fibers, which differ in the diameters of the quartz cladding and polymer coating, is carried out. An analytical estimate of the lifetime is carried out.

Abstract:
Polarization-maintaining (PM) fiber is the core sensitive component of a fiber optic gyroscope (FOG); its birefringence temperature stability is crucial for maintaining accuracy. Here, we systematically investigated the structural thermal deformation and the resulting birefringence variation in typical PM hollow-core photonic bandgap fibers (HC-PBGFs) for FOG according to varying fiber structure parameters. To verify the application potential of PM HC-PBGFs in FOG, we compared the thermal sensitivity of birefringence (TSB) with that of the commonly used Panda PM fiber, which was tested to 5.07

Abstract:
Grazing is the primary human-induced disturbance affecting giant panda (Ailuropoda melanoleuca) habitats and has a severe impact on the long-term sustainability of the giant panda population. To address the lack of quantitative studies on grazing’s impact on habitat quality, we selected China’s most heavily grazed giant panda nature reserve. Utilizing the Maxent model and stoichiometric analysis, we investigated habitat quality degradation caused by grazing and quantified changes in bamboo nutritional quality and soil physicochemical properties. The results indicate that grazing has significan

Abstract:
Fiber Sagnac loop mirror has great potential for use in various application such as multi-wavelength laser source, strain and temperature sensors. This paper demonstrates an optical fiber temperature sensor based on two lengths of PANDA polarization maintaining fibers (PMFs) in a fiber Sagnac interferometer. The temperature sensing is based on the change of spectral spacing of the generated optical comb with the temperature difference between two PMFs. The performance of the system was characterized numerically and experimentally by measuring the spectral spacing when raising the temperature o

Abstract:
Abstract The use of Panda-type polarization-maintaining (PM) fiber for the localized sensing of high temperatures was analyzed with simulations and experiments up to 900°C. Accuracy and repeatability of the results started to decline above 800°C. Fused silica optical fiber melts at 1700°C, which sets an ultimate limit for measurable temperatures. In practice, optical fiber birefringence restricts the maximum temperature to 1060°C where PM fiber loses its ability to maintain polarization. Three sensor fibers (4, 5 and 10 cm long) were spliced at 45° angles to input/output fibers and calibrated

Abstract:
The giant panda (Ailuropoda melanoleuca) has evolved a large number of mucous glands in the intestinal lining to adapt to the digestion of high-fiber foods. However, in captive pandas, excessive mucus might form a mass and then be eliminated, which is often accompanied by discomfort and decreased activity. This event is called ‘mucous excretion’. The causes of mucus excretions in captive pandas, however, remain unknown. The aims of this study were to document the occurrence of mucus excretion and to investigate its possible associations with pandas’ age, gender, and feces output. Eighteen gian

Abstract White Matter Pathways are the train-tracks of the nervous system. If they are interrupted, impulses stagnate. Historically, the number of publications on white matter has paled in comparison to that on gray matter. However, now, with diffusion tensor imaging and other radiographic techniques dedicated to imaging the white matter pathways, much is being learned about their anatomy. Recent attempts to clarify white matter anatomy using audiographic and diffusion spectrum imaging techniques were compiled in a remarkable book entitled Fiber Pathways of the Brain, by Jeremy Schmahmann and
