Background Many factors interfering with a listener attempting to grasp speech in noisy environments. The spatial hearing by which speech and noise can be spatially separated may play a crucial role in speech recognition in the presence of competing noise. This study aimed to assess whether, and to what degree, spatial hearing benefit speech recognition in young normal-hearing participants in both quiet and noisy environments. Methods Twenty-eight young participants were tested by Mandarin Hearing In Noise Test （MHINT） in quiet and noisy environments. The assessment method used was characterized by modifications of speech and noise configurations, as well as by changes of speech presentation mode. The benefit of spatial hearing was measured by speech recognition threshold （SRT） variation between speech condition 1 （SC1） and speech condition 2 （SC2）. Results There was no significant difference found in the SRT between SC1 and SC2 in quiet. SRT in SC1 was about 4.2 dB lower than that in SC2, both in speech-shaped and four-babble noise conditions. SRTs measured in both SC1 and SC2 were lower in the speech-shaped noise condition than in the four-babble noise condition. Conclusion Spatial hearing in young normal-hearing participants contribute to speech recognition in noisy environments, but provide no benefit to speech recognition in quiet environments, which may be due to the offset of auditory extrinsic redundancy against the lack of spatial hearing.

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.

目的探讨阻塞性睡眠呼吸暂停综合征(obstructive sleep apnea-hypopnea syndrome,OSAHS)患者对糖代谢紊乱发生的影响。方法选择空腹或餐后血糖升高的OSAHS患者9例,进行常规手术或持续正压通气治疗。所有患者治疗前、后均进行多导睡眠监测和空腹血糖(FPG)、餐后2h血糖(2HPG)、空腹胰岛素、空腹C-肽、糖化血红蛋白Alc(HbAlc)测定以及入睡后每隔2h的血糖测定。结果伴有糖代谢紊乱的OSAHS患者夜间血糖升高,治疗后夜间血糖明显下降。患者空腹血糖和糖化血红蛋白治疗后与治疗前相比均有所下降,而其餐后2h血糖变化不明显。OSAHS患者胰岛素敏感性指数随着OSAHS病情好转接近正常。结论伴糖代谢紊乱的OSAHS患者,其夜间血糖升高,且这种血糖升高与OSAHS密切相关。OSAHS可作为糖代谢紊乱的一个独立危险因素,可加重伴糖代谢紊乱的OSAHS患者的胰岛素抵抗。
