Human activity recognition system based on low-cost IoT chip ESP32 by Chao HU, Bangyan LU, Yanbing YANG, Zhe CHEN, Lei ZHANG, Liangyin CHEN

“…Human activity recognition widely exists in applications such as sports management and activity classification.The current human activity recognition applications are mainly divided into three types: camera-based, wearable device-based, and Wi-Fi awareness-based.Among them, the camera-based human activity recognition application has the risk of privacy leakage, and the wearable device-based human activity recognition application has problems such as short battery life and poor accuracy.Human activity recognition based on Wi-Fi sensing generally uses Wi-Fi network cards or software-defined radio devices to identify the rules of channel state information changes, so as to infer user activity.It does not have the problems of privacy leakage and short battery life.But Wi-Fi network cards need to rely on computers and software-defined radio platforms are expensive, which greatly limit the application scenarios of Wi-Fi sensing.Aiming at the above problems, a human activity recognition system based on the low-cost IoT chip ESP32 was proposed.Specifically, the Hampel filter and Gaussian filter were used to preprocess the channel state information obtained by ESP32.Then, the principal component analysis and discrete wavelet transform were utilized to reduce the dimension of the data.Finally, the K-nearest neighbor (KNN) algorithm was applied to classify data.The experimental results show that the system can achieve a recognition accuracy which close to the current mainstream Wi-Fi perception system (Intel 5300 network card) when only two ESP32 nodes are deployed, and the average accuracy rate for the six activities is 98.6%.…”

Cis‐Regulation of an m6A Eraser by an Insertion Variant Associated with Survival of Patients With Non‐Small Cell Lung Carcinoma by Lei Cheng, Qiangsheng Hu, Yanan Wang, Wei Nie, Haijiao Lu, Bo Zhang, Genming Zhao, Shiyun Ding, Feng Pan, Yinchen Shen, Runbo Zhong, Ruoxin Zhang

“…Then, ALKBH5 upregulated FBXL5 expression by m6A demethylation, which is dependent on the ALKBH5 H204 amino acid site and specific m6A sites on FBXL5 mRNA. Finally, the ALKBH5‐FBXL5 axis reduces intracellular reactive oxygen species levels, leading to PI3K/AKT and NF‐kB pathway inhibition and consequently suppresses NSCLC proliferation and metastasis in vitro and in vivo. …”

Analysis of the elasticity of demand for bread by Marina Lolić Čipčić, Doris Cvitković

“…The range of the calculated coefficients of price elasticity of demand is significantly higher when the campaign is introduced, in other words, the introduction of the pricing campaign reduced the sensitivity of customers to price changes in the short term, i.e. after the end of the pricing campaign sales increase despite the return of prices to the levels that preceded the campaign. Finally, the calculation of the coefficients of income elasticity of demand implies that, for all selected types, bread is considered to be a normal good.…”
