Background： Nowadays, it is widely known that decremental responses in low-frequency repetitive nerve stimulation （LF-RNS） are frequently observed in patients with amyotrophic lateral sclerosis （ALS）. The pathological mechanism of this phenomenon remains unknown. This study aimed to illuminate the features of RNS in Chinese patients with ALS. Methods： Clinical and electrophysiological data of 146 probable and definite ALS patients who underwent RNS were retrospectively enrolled and analyzed. LF-RNS （3 Hz） was performed in trapezius, deltoid, abductor digiti minimi （ADM）, quadriceps femoris, and tibialis anterior. High-frequency RNS （HF-RNS, 10 Hz） was performed only in ADM. The two-sample t-test and Chi-squared test were used for statistical ***： Decremental responses to LF-RNS （≥ 10%） in at least one muscle were detected in 83 （56.8%） of the cases and were most commonly seen in trapezius and deltoid. The incidence ofdecremental response was higher in patients with upper limb onset. Incremental responses to HF-RNS （≥60%） in ADM were observed in 6 （5.6%） of the cases. In 106 muscles with decremental response, 62 （57.4%） muscles had a continuous decremental pattern, more than a U-shape pattern （37 cases, 34.3%）. Nineteen cases showed definite decrements in LF-RNS tests in trapezius, while no abnormalities were found in the electromyography and neurological examination of the sternocleidomastoid muscle, supplied by the accessory nerve as ***： Decremental responses in the RNS are commonly observed in ALS patients. The findings regarding the trapezius indicated that some ALS onsets could be initiated by a ＂dying back＂ process, with destruction of neuromuscular junctions （NMJs） before motor neurons. Incremental responses in the ADM implied damage of the NMJs involved both the post and presynaptic membranes.

This note is concerned with the absolutestability for time-varying delay Lur’e system withsector-bounded nonlinearity. Improved delay-dependentand delay-derivative-dependent stability criteria areobtained in the form of linear matrix inequalities (LMIs)by constructing a modified augmented Lyapunov-Krasovskii (LK) functional without applying the modeltransformation or the bounding techniques for crossterms. Thus, the presented delay-dependent criteria areless conservative than those in the literature. Moreover,state feedback stabilizing controllers based on theproposed stability criteria are designed. Numericalexample demonstrates the effectiveness and superiorityof the proposed method.

The dispersive Fourier transform(DFT) technique opens a fascinating pathway to explore ultrafast non-repetitive events and has been employed to study the build-up process of mode-locked lasers. However, the shutting process for the mode-locked fiber laser seems to be beyond the scope of researchers, and the starting dynamics under nearzero dispersion remains unclear. Here, the complete evolution dynamics(from birth to extinction) of the conventional soliton(CS), stretched pulse(SP), and dissipative soliton(DS) are investigated by using the DFT ***, SP, and DS fiber lasers mode locked by single-walled carbon nanotubes(SWNTs) are implemented via engineering the intracavity dispersion map. The relaxation oscillation can always be observed before the formation of stable pulse operation due to the inherent advantage of SWNT, but it exhibits distinct evolution dynamics in the starting and shutting processes. The shutting processes are dependent on the dispersion condition and turn-off time, which is against common sense. Some critical phenomena are also observed, including transient complex spectrum broadening and frequency-shift interaction of SPs and picosecond pulses. These results will further deepen understanding of the mode-locked fiber laser from a real-time point of view and are helpful for laser design and applications.
