NLRP3 in the Cerebrospinal Fluid as a Potential Biomarker for the Diagnosis and Prognosis of Community-Acquired Bacterial Meningitis in Adults

Frontiers in Cellular and Infection Microbiology (2022)

Zhe Gong Chaopeng Zhang Yanfei Li Lijun Jing Ranran Duan

Objective To discover the levels of NLR family pyrin domain-containing 3 (NLRP3) in the cerebrospinal fluid (CSF) from adult patients with community-acquired bacterial meningitis (CABM). Methods We enrolled 34 patients with CABM, 20 patients with viral meningitis (VM), and 25 patients with non-inflammatory neurological disease. Data on standard clinical parameters, scores, and outcomes were obtained from clinical records, and inflammasome levels in the CSF were measured by an enzyme-linked immunosorbent assay. The area under the receiver operating characteristic curve (AUROC) was used to quantify the diagnostic and prognostic performance of CSF NLRP3 as a biomarker of CABM. Results The levels of NLRP3 were elevated in the CSF of patients with CABM, but levels for ASC, caspase-1, or other inflammasomes did not vary significantly. CSF NLRP3 was positively correlated with clinical severity and with the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte count, albumin quotient (Qalb), and immunoglobulin G quotient (QIgG). Patients with unfavorable outcomes had higher levels of NLRP3 in the CSF, which were correlated with several blood indicators, including NLR, PLR, and lymphocyte and monocyte counts. Conclusions Our results suggested that the level of CSF NLRP3 could represent the severity of CABM in adults. CSF NLRP3 may be a good biomarker for the diagnosis of CABM and for the discrimination between CABM and VM. It may also be a better biomarker for predicting the prognosis of adult patients with CABM when compared to the NLR or the lymphocyte and monocyte counts.

Online Accurate Estimation of the Wheel-Rail Adhesion Coefficient and Optimal Adhesion Antiskid Control of Heavy-Haul Electric Locomotives Based on Asymmetric Barrier Lyapunov Function

Journal of Sensors (2018)

Kaihui Zhao Peng Li Changfan Zhang Jing He Yanfei Li

This paper proposes a new scheme of online accurate estimation of wheel-rail adhesion coefficient and optimal adhesion antiskid control of heavy-haul electric locomotives (HHEL) based on sliding mode and asymmetric barrier Lyapunov function (ABLF) theory. To achieve optimal adhesion control of the HHEL, it is necessary to precisely estimate the wheel-rail adhesion coefficient. However, the adhesion coefficient is difficult to be measured with a conventional physical sensor. The first novelty of this paper is to design a smart adhesion coefficient sensor based on sliding mode observer (SMO). The perception of the adhesion coefficient is transformed into the observation of load torque of the traction motors, and the wheel-rail adhesion coefficient is further calculated by using the load torque observed value. The HHEL achieves maximum traction from operating in the optimal adhesion point. However, wheel skidding is most likely to occur at this point. According to the changing trend of the adhesive coefficient characteristic curve, the operating state of a locomotive can be divided into two regions: the stable and skid regions. The second novelty of this paper is the adaptation of ABLF to guarantee that the HHEL operated at a stable region and the optimal adhesion antiskid control of HHEL is achieved. Finally, the simulation and experimental results verify the feasibility and effectiveness of the proposed method.

Experimental study on carbon dioxide refrigeration system combined with liquid desiccant dehumidification

International Conference on Advanced Manufacturing Technology and Manufacturing Systems (ICAMTMS 2022) (2022)

Wanrong Shi Qiaolian Feng Xiao Liang Dehua Cai Yanfei Li

The tropical marine environment is characterized by high temperature and high humidity, and the service life of electrical equipment will be greatly shortened under such high humidity. Traditional dehumidification technologies such as condensation dehumidification have low-efficiency issues; rotary dehumidification system takes up a lot of space and costs high; solid desiccant dehumidification system's regeneration rate is slow and dehumidification efficiency is low. In the current trend of refrigerant researchers pursuing environmental friendliness and high energy efficiency, in this paper, the transcritical CO₂ (T-CO₂) compression refrigeration system is jointed with the liquid desiccant dehumidification circle, and the compressor's exhaust heat is directed into the regenerator of the dehumidification system to regenerate the desiccant solution. According to experimental studies, this design improves the overall COP of the system from 2.61 (the CO₂ cycle alone) to 3.83 (the jointed system). This jointed system solves the mismatch of dehumidification & refrigeration load and inefficiency of condensing dehumidification in ordinary refrigeration systems, and effectively utilizes the high-grade exhaust heat of the T-CO₂ refrigeration system, solving the inefficiency of the T-CO₂ refrigeration cycle.

Hydrogen as Energy Storage for Renewables in East Asia: Economic Competitiveness and Policy Implications

Yanfei Li Farhad Taghizadeh‐Hesary

Hydrogen energy provides an option to integrate renewable energy into the energy mix and increase its share. Hydrogen is also a means to couple renewable energy and the transport sector. This study investigates the economics of hydrogen as energy storage for renewables in the Association of Southeast Asian Nations and East Asian countries. Subsequently, the study analyzes downstream applications of hydrogen energy in power generation and in road transport, respectively. In the case of power sector, the cost of electricity stored as hydrogen and then returned to the grid as electricity is estimated in United States (US) dollars per kilowatt-hour and compared with the electricity stored using lithium batteries and pumped-hydro. In the case of transport sector, the total cost of fuel cell electric vehicles is estimated in US dollars per kilometer and compared with alternative powertrains such as battery electric vehicles, plug-in hybrid electric vehicles, and internal combustion engine vehicles. Hydrogen and its downstream applications are not competitive against other mature alternatives at this moment. The study indicates how big the cost gaps are and shows that significant economies of scale exist in hydrogen supply pathways. We expect factors such as technological progress, learning effects, maturing of the supply chain, and economies of scale to substantially reduce the cost of hydrogen and its applications and make them economically competitive in the near future. Case studies on hydrogen energy companies in China and Japan further complement the findings from the modelling analysis. We draw policy implications based on these findings.

Effect of particle size on the microstructure and tensile property of the Al-28.5Si alloy prepared by continuous powder extrusion

Materials Research Express (2021)

Jiancheng Yin Yanfei Li Yingshuo Niu Zitan Zhang Dan Song

Abstract Continuous powder extrusion, a new powder consolidation technology, is used to process alloy powders that are difficult to form. In the paper, Al-28.5Si alloys were successfully prepared by continuous powder extrusion, and the influences of particle size on the microstructure and tensile property have been investigated. In the as-extruded rods, the primary Si phase is dispersed in the α -Al matrix. As the powder size reduces from more than 75 μ m to less than 25 μ m, the equivalent diameter of the primary Si particles consecutively decreases, but the shape factor increases. Comparing the Si particles in the alloy rod and the powder, it is found that the eutectic Si phase disappears during continuous extrusion. Primary Si particles change from coarse and irregular to round. Specifically, the ultimate tensile strength and elongation at break of the powder-extruded alloy further increase from 211 MPa to 266 MPa and 0.99% to 2.21%. Moreover, the fracture mechanism of alloy rods is the brittle fracture.
