Abstract

Dissipative Kerr soliton microcombs in microresonators has enabled fundamental advances in chip scale precision metrology, communication, spectroscopy, and parallel signal processing. Here we demonstrate polarization diverse soliton transitions and deterministic switching dynamics of a self stabilized microcomb in a strongly coupled dispersion-managed microresonator driven with a single pump laser. The switching dynamics are induced by the differential thermorefractivity between coupled transverse magnetic and transverse electric supermodes during the forward backward pump detunings. The achieved large soliton existence range and deterministic transitions benefit from the switching dynamics, leading to the cross polarized soliton microcomb formation when driven in the transverse magnetic supermode of the single resonator. Resultantly the pump laser always exists at the effective blue detuning of the transverse magnetic resonance, fundamentally mitigating the thermal destabilization barrier and improving accessibility of the soliton formation regime. Subsequently and secondly, we demonstrate two distinct polarization diverse soliton formation routes arising from chaotic or periodically modulated waveforms via pump power selection. The generated self stabilized supermode microcomb features an extraordinarily large soliton existence range, a variety of soliton state transitions with well defined pump laser tuning, high pump microcomb conversion efficiency, and low repetition rate phase noise.

Abstract

Purpose: Substantial evidence has established a strong association between non-alcoholic fatty liver disease (NAFLD), type 2 diabetes mellitus (T2DM) and insulin resistance (IR). Insulin resistance metabolic score (METS-IR) is a new and more effective comprehensive indicator for measuring IR. Our aim was to investigate the relationship between METS-IR and NAFLD in T2DM population. Patients and methods: This cross-sectional study included 1097 adult patients with T2DM. Anthropometric measurements and biochemical indicators were collected, and the NAFLD was diagnosed by ultrasound. The METS-IR was calculated. Based on the presence of NAFLD, the population was divided into non-NAFLD and NAFLD groups. The relationship between METS-IR and NAFLD was evaluated. Results: Compared with the non-NAFLD group, the METS-IR was higher in the NAFLD group (P < 0.001). The incidence rate of NAFLD increased across the quartiles of the METS-IR (P < 0.001). Spearman correlation analysis showed that METS-IR was positively correlated with NAFLD (Correlation Coefficient: 0.441, P < 0.001). The binary logistic regression analysis indicated that METS-IR was independently associated with NAFLD (OR: 1.120, 95% CI 1.080– 1.161). Furthermore, the area under the receiver operating characteristic curve of the METS-IR was 0.781 (95% CI 0.746– 0.817) and relatively higher than other evaluation variables. Conclusion: In patients with T2DM, METS-IR is closely associated with NAFLD, and might be a valuable predictor of NAFLD. Further research is needed to verify this association. [ABSTRACT FROM AUTHOR]

Abstract

With the widely application of the Wireless Sensor Network, it is particularly significant to assure a secure communication mechanism between the nodes. In order to meet the needs of sensor nodes on low power consumption and less resource, lightweight cryptographic algorithm designed well is the key to constructing a riskless WSN scheme. In this paper, we propose an improved elliptic curve cryptography digital signature scheme by means of optimizing the multiplicative inverse module of ECDSA, based on ECC lightweight cryptographic algorithm. Moreover, we implement ECDSA scheme improved on Micaz, which is a kind of sensor network platform. And then, experimental results demonstrate that the performance of improved scheme is superior to the previous, not only on the speed but also on the efficiency, under the same experimental environment and encryption intensity. In a word, our scheme has stronger practicability.
