This study presents a high-accuracy,all-fber mode division multiplexing(MDM)reconstructive spectrometer(RS).The MDM was achieved by utilizing a custom-designed 3×1 mode-selective photonics lantern to launch distinct spatial modes into the multimode fber(MMF).This facilitated the information transmission by increasing light scattering processes,thereby encoding the optical spectra more comprehensively into speckle *** resolution of 2 pm and the recovery of 2000 spectral channels were *** to methods employing single-mode excitation and two-mode excitation,the three-mode excitation method reduced the recovered error by 88%and 50%respectively.A resolution enhancement approach based on alternating mode modulation was proposed,reaching the MMF limit for the 3 dB bandwidth of the spectral correlation *** proof-of-concept study can be further extended to encompass diverse programmable mode *** is not only succinct and highly efcient but also well-suited for a variety of high-accuracy,high-resolution spectral measurement scenarios.

Objective: This analysis was conducted to clarify risk factors for chemotherapy-induced leukopenia (CIL) in lung cancer. Methods: A retrospective study was conducted on data from 358 patients with lung cancer who received chemotherapy. Results: Among 358 cases of lung cancer who received chemotherapy, a total of 240 patients experienced CIL, rate was 67%. The demographic data including gender (P = 0.795), age (P = 0.134), presence of selected chronic comorbidities (P = 0.23) were not significantly different in the two groups. The weight loss rate, PS score, sub-normal pre-WBC level, sub-normal pre-PLT level, and the cycle of chemotherapy were significantly different between the groups (P < 0.05). Multivariate analysis revealed that the weight loss rate ≥5% (OR = 0.503), sub-normal pre-WBC level (OR = 11.807), the cycle of chemotherapy ≥3 (OR = 3.100) were main risk factors for CIL in lung cancer. Conclusion: Before treatment, weight loss rate is 5% or higher, chemotherapy has a cycle of 3 or more and sub-normal WBC level is independent risk factor of lung cancer after chemotherapy-induced leucopenia.
