Odorant discrimination using functional near-infrared spectroscopy of the main olfactory bulb in rats

We characterize the hemodynamic response changes near-infrared spectroscopy （NIRS） during the presentation of in the main olfactory bulb （MOB） of anesthetized rats with three different odorants： （i） plain air as a reference （Blank）, （ii） 2-heptanone （HEP）, and （iii） isopropylbenzene （Ib）. Odorants generate different changes in the concentrations of oxy- hemoglobin. Our results suggest that NIRS technology might be useful in discriminating various odorants in a non-invasive manner using animals with a superb olfactory system.

The effects of prolonged sitting behavior on resting-state brain functional connectivity in college students post-COVID-19 rehabilitation:A study based on fNIRS technology

Functional near-infrared spectroscopy(fNIRS)was used to explore the effects of sedentary behavior on the brain functional connectivity characteristics of college students in the resting state after recovering from Corona Virus Disease 2019(COVID-19).Twenty-two college students with sedentary behavior and 22 college students with sedentary behavior and maintenance of exercise habits were included in the analysis;moreover,8 min fNIRS resting-state data were collected.Based on the concentrations of oxyhemoglobin(HbO2)and deoxyhemoglobin(HbR)in the time series,the resting-state functional connection strength of the two groups of subjects,including the prefrontal cortex(PFC)and the lower limb supplementary motor area(LS),as well as the functional activity and functional connections of the primary motor cortex(M1)were calculated.The following findings were demonstrated.(1)Functional connection analysis based on HbO2 demonstrated that in the comparison of the mean functional connection strength of homologous regions of interest(ROIs)between the sedentary group and the exercise group,there was no significant difference in the mean functional strength of the ROIs between the two groups(p>0:05).In the comparison of the mean functional connection strengths of the two groups of heterologous ROIs,the functional connection strengths of the right PFC and the right LS(p?0:0097),the left LS(p?0:0127),and the right M1(p?0:0305)in the sedentary group were significantly greater.The functional connection strength between the left PFC and the right LS(p?0:0312)and the left LS(p?0:0370)was significantly greater.Additionally,the functional connection strength between the right LS and the right M1(p?0:0370)and the left LS(p?0:0438)was significantly greater.(2)Functional connection analysis based on HbR demonstrated that there was no significant difference in functional connection strength between the sedentary group and the exercise group(p>0:05)or between the sedentary group and the exercise group(p>0:05).Similarly,there was no significant difference in the mean functional connection strength of the homologous and heterologous ROIs of the two groups.Additionally,there was no significant difference in the mean ROIs functional strength between the two groups(p>0:05).Experimental results and graphical analysis based on functional connectivity indicate that in this experiment,college student participants who exhibited sedentary behaviors showed an increase in fNIRS signals.Increase in fNIRS signals among college students exhibiting sedentary behaviors may be linked to their status post-SARS-CoV-2 infection and the sedentary context,potentially contributing to the strengthened functional connectivity in the resting-state cortical brain network.Conversely,the fNIRS signals decreased for the participants with exercise behaviors,who maintained reasonable exercise routines under the same conditions as their sedentary counterparts.The results may suggest that exercise behaviors have the potential to mitigate and reduce the impacts of sedentary behavior on the resting-state cortical brain network.

基于KDLV算法的配电网环网柜故障检测模型

环网柜作为配电系统中的关键连接点,其状态监测数据通常具有非线性、动态性和多变量相关性等特点。为了克服传统环网柜故障检测模型对状态特征信息提取不够充分导致监测效果不佳的问题,提出一种基于核动态潜变量(KDLV)算法的故障检测模型。首先利用KDLV算法将提取的多变量信息划分为动态潜变量部分和静态潜变量部分。然后对动态部分构建VAR模型,并构造特征空间的T^(2)监控统计量;对静态部分构建NPE模型,并分别构造数据特征空间和残差空间的T^(2)和SPE监控统计量。最后综合状态数据的动静态统计限,实现对实时数据的在线监控。通过现场试验数据验证,模型的故障检测率为100%,误报率最高为1.20%,相较于传统的环网柜故障检测模型,提出的模型更具优势。
