[Analysis of Carbon Emission Characteristics and Influencing Factors in Urban Wastewater Collection Systems under the Background of Quality Improvement and Efficiency Enhancement].

Against the background of today's increasingly serious global climate change problem, this study focuses on the carbon emission problem of urban drainage systems and proposes a carbon accounting method for the operation stage of urban drainage systems based on the emission factor method and mass balance idea. The method considered CH from biochemical reactions of pollutants in the drain, CH and NO from biochemical reactions of uncollected pollutants, and carbon emission from the electrical consumption of equipment such as lifting pumping stations, and the application was carried out based on the operational data of the case city from 2019 to 2022. The results of the study showed that the total carbon emission from the drainage system in the five areas （Ⅰ, Ⅱ, Ⅲ,Ⅳ, and V） of the case city decreased from 50,186 t in 2019 to 35,134 t in 2022.

Prognostic and clinicopathological value of osteopontin expression in non-small cell lung cancer: a meta-analysis and systematic review.

Background: Although Osteopontin (OPN) has been reported to be associated with many different human cancers, the data on non-small cell lung cancer (NSCLC) are not definitive. This study aimed to explore the prognostic effect of OPN expression and clinicopathological characteristics in patients with NSCLC.

Methods: This study followed all aspects of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) report.

Acute and 28-Day Repeated-Dose Oral Toxicity of the Herbal Formula Guixiong Yimu San in Mice and Sprague-Dawley Rats.

To evaluate the acute and chronic 28-day repeated-dose oral toxicity of Guixiong Yimu San (GYS) in mice and rats, high-performance liquid chromatography (HPLC) was used to determine the stachydrine hydrochloride in GYS as the quality control. In the acute toxicity trial, the mice were administered orally at a dose rate of 30.0 g GYS/kg body weight (BW) three times a day.

Effect of Comprehensive Care Based on Appropriate Chinese Medicine Techniques on Urinary Retention and Bladder Function Recovery after Total Hysterectomy in Patients with Cervical Cancer.

Objective: To investigate the effect of comprehensive care based on appropriate Chinese medicine techniques on urinary retention and bladder function recovery after total hysterectomy in patients with cervical cancer.

Methods: A total of 148 cases admitted after radical hysterectomy for cervical cancer from January 2019 to early September 2019 were used as the observation sample and were divided into control and experimental groups based on a randomized double-blind method. There were 74 cases each.

Cluster decomposing and multi-objective optimization based-ensemble learning framework for motor imagery-based brain-computer interfaces.

. Motor imagery (MI) is a mental representation of motor behavior and a widely used pattern in electroencephalogram (EEG) based brain-computer interface (BCI) systems. EEG is known for its non-stationary, non-linear features and sensitivity to artifacts from various sources.

Combined Stochastic Process and Value at Risk: A Real-World Information System Decision Case.

In this study, we used a combined stochastic process and value-at-risk (VaR) method to examine an electronic commerce expansion decision. By modeling uncertain benefits as a stochastic process, maximum losses of alternative decisions were quantified and compared to help managers to make information system/information technology (IS/IT) project decisions. Our results, based on the maximum loss perspective, demonstrated that uncertainty plays a critical role in evaluating IS/IT projects.

Temporal frequency joint sparse optimization and fuzzy fusion for motor imagery-based brain-computer interfaces.

Background: Motor imagery (MI) related features are typically extracted from a fixed frequency band and time window of EEG signal. Meanwhile, the time when the brain activity associated with the occurring task varies from person to person and trial to trial. Thus, some of the discarded EEG data with time may contain MI-related information.

Interacting multiple model-based adaptive control system for stable steering of distributed driver electric vehicle under various road excitations.

Distributed driver electric vehicle (DDEV) works under various road excitations in practice, which may cause the changes in steering performance significantly. However, the various road excitations are not a priority for stable steering problem of DDEV, and this possibly leads to unstable steering performance, particularly oversteer or tail flick. To solve this problem, an interacting multiple model-based adaptive control system (IMM-ACS) is presented in this work.

Tracking Performance Limitations of MIMO Networked Control Systems With Multiple Communication Constraints.

In this paper, the tracking performance limitation of networked control systems (NCSs) is studied. The NCSs are considered as continuous-time linear multi-input multioutput (MIMO) systems with random reference noises. The controlled plants include unstable poles and nonminimum phase (NMP) zeros.

Nitrogen isotope variations in camphor (Cinnamomum Camphora) leaves of different ages in upper and lower canopies as an indicator of atmospheric nitrogen sources.

Nitrogen isotopic composition of new, middle-aged and old camphor leaves in upper and lower canopies has been determined in a living area, near a motorway and near an industrial area (Jiangan Chemical Fertilizer Plant). We found that at sites near roads, more positive δ(15)N values were observed in the camphor leaves, especially in old leaves of upper canopies, and ∆δ(15)N=δ(15)N(upper)-δ(15)N(lower)>0, while those near the industrial area had more negative δ(15)N values and ∆δ(15)N<0. These could be explained by two isotopically different atmospheric N sources: greater uptake from isotopically heavy pools of atmospheric NO(x) by old leaves in upper canopies at sites adjacent to roads, and greater uptake of (15)N-depleted NH(y) in atmospheric deposition by leaves at sites near the industrial area.

Objective: To investigate the feasibility and possible mechanism of non traditional hepatic lobectomy using nitinol alloy net blocker of biliary intrahepatic duct.

Methods: Biliary intrahepatic ducts of the experimental pigs were blocked with and without dissepiment blockers. The histological changes and expressions of TGF-betal and TIMP-1 in the livers were compared.

[Effect of ligand pioglitazone activating PPAR-gamma on the invasiveness of cholangiocarcinoma cell in vitro and the expression regulation of related genes].

Objective: To explore the effect and mechanism of ligand pioglitazone (PGZ) activating PPAR-gamma on the invasiveness of cholangiocarcinoma cell in vitro.

Methods: Human hilar cholangiocarcinoma cell line QBC939 was selected and cultured in vitro for this research. The rate of QBC939 cell growth inhibition was detected by MTT, and the influence of PGZ on the expression of MMP-7 mRNA and TIMP-1 mRNA was measured by using FQ-PCR.

Objective: To investigate the effect that PPAR-gamma (peroxisome proliferator-activated receptor gamma, PPAR-gamma) ligand rosiglitazone (rosiglitazone, RGZ) inhibits the cell proliferation of cholangiocarcinoma.

Methods: The cell line QBC939 of cholangiocarcinoma was interfered with different concentration of RGZ, and then calculated for the rate of cell proliferation inhibited at different concentration. The change of cell cycle and the rate of cell apoptosis at each concentration were detected by FCM.

Objective: To evaluate radial artery (RA) and internal mammary artery (IMA) grafts in coronary artery bypass and the use of color Doppler ultrasound in the peri-operative evaluation of IMA and radial-ulnar collateral circulation.

Methods: From June 1998 to June 2000, sixty cases of coronary bypass revascularization with RA and IMA were performed. Preoperatively, the radial-ulnar collateral circulation was evaluated with the modified Allen's test, color Doppler ultrasound and noninvasive oxygen saturation measurement.
