19 F MRI and optical imaging are two powerful noninvasive molecular imaging modalities in biomedical applications. 19 F MRI has great potential for high resolution in vivo imaging, while fluorescent probes enable ultracontrast cellular/tissue imaging with high accuracy and sensitivity. A bimodal nanoprobe is developed, integrating the merits of 19 F MRI and fluorescence imaging into a single synthetic molecule, which is further engineered into nanoprobe, by addressing shortcomings of conventional ...

In conventional air-conditioning system, fresh air volume is always restricted to save energy, which sacrifices indoor air quality (IAQ) to some extent. However, removing the latent load of air by liquid desiccant rather than by cooling is an alternative way of reducing energy consumption. Therefore, IAQ can be improved by increasing the volume of fresh air introduced into an air-conditioning system. In this paper, a liquid desiccant based air-conditioning system is studied, with the system performance ...

Abstract Liquid desiccant and heat pump (LDHP) hybrid air-conditioning system provides a promising independent air dehumidification solution. Capacity matching among the four major heat and mass transfer components, i.e. dehumidifier, regenerator, evaporator and condenser, is essentially important for energy efficiency of the hybrid system. In this paper, the configuration of the hybrid system is firstly studied. Novel matching indices are proposed to evaluate the matching effect. The results show ...

The uncertainty and regularity of wind power generation are caused by wind resources’ intermittent and randomness. Such volatility brings severe challenges to the wind power grid. The requirements for ultrashort-term and short-term wind power forecasting with high prediction accuracy of the model used, have great significance for reducing the phenomenon of abandoned wind power , optimizing the conventional power generation plan, adjusting the maintenance schedule and developing real-time monitoring ...

Membrane-based total heat exchanger is a device to recover both sensible heat and moisture from exhaust air stream from a building. Heat and mass transfer intensification has been undertaken by using a structure of cross-corrugated triangular ducts. To further intensify moisture transfer, recently developed membranes-one step made asymmetric membranes, are used as the exchanger materials. Conjugate heat and mass transfer under transitional flow regime in this total heat exchanger are investigated. ...

The extent of research on maternal exercise during pregnancy and the risk of preterm birth (PTB) have grown substantially, but conclusions still remained controversial. Thus, this study aims to examine the relationship of maternal exercise during pregnancy and PTB and explore whether placenta mediates their relationship.We investigated 849 pregnant women delivering PTB newborns (cases) and 1306 delivering full-term appropriate for gestational age newborns (controls) in this case-control study.

Evidence regarding the association between prenatal exposure to cooking oil fumes (COF) and full-term low birth weight (FTLBW) is still controversial, and the mechanism remains unclear. This study thus aims to explore the association of prenatal COF exposure with off-spring FT-LBW as well as the mediating role of placenta in their association. A case-control study enrolling 266 pregnant women delivering FTLBW newborns (cases) and 1420 delivering normal birth weight (NBW) newborns (controls) was conducted. ...

Jacobian-free Newton Krylov (JFNK) method is an advanced numerical method for solving the transient multi-physics coupling problem in nuclear reactor, where all the coupled equations are simultaneously solved in a tightly nonlinear form. Constructing a high performance preconditioning is a key issue for JFNK method to efficiently solve this complex coupled system. Two families of preconditioning method, linear preconditioning and nonlinear preconditioning, have been proposed and developed independently. ...

Electroencephalogram (EEG) based brain-computer interfaces (BCI) in motor imagery (MI) have developed rapidly in recent years. A reliable feature extraction method is essential because of a low signal-to-noise ratio (SNR) and time-dependent covariates of EEG signals. Because of efficient application in various fields, deep learning has been adopted in EEG signal processing and has obtained competitive results compared with the traditional methods. However, designing and training an end-to-end network ...

Fluorescent temperature sensing materials are generally designed based on the phenomenon that the fluorescence intensity ratio (FIR) of luminescence at different wavelength positions changes linearly with temperature. Luminescence at different wavelength positions can come from two different luminescent centers. The key to the design of such materials is that the two luminescent centers have different degrees of change with temperature, that is, they have different thermal quenching behavior. Herein, ...

The quantitative analysis of nanoparticles (NPs) in the environment is significantly important for the exploration of the occurrence, fate, and toxicological behaviors of NPs and their subsequent environmental risks. Some protocols have been recommended for the separation and extraction of NPs that are potentially dispersed in complex environmental matrixes, e.g. sediments and soils, but they remain limited. However, certain factors that may significantly affect extraction efficiency have not been ...

Fabrication of novel proton exchange membrane (PEM) is crucial to the development of direct methanol fuel cells (DMFCs). Here, molybdenum disulfide (MoS2) nanosheets were anchored onto carbon nanotubes (CNTs) via a facile in-situ growth method, and then a series of composite PEMs were fabricated via embedding MoS2-coated CNTs (MoS2@CNTs) in the sulfonated polyether ether ketone (SPEEK) matrix. The coating of MoS2 nanosheets improved the dispersibility and compatibility with the polymer matrix and enhanced ...

Newton-Krylov (NK) method with the explicit Jacobian matrix is a promising method to solve the nonlinear multi-physics coupling system. However, how to form the Jacobian matrix efficiently is a key issue that is the most cumbersome step in NK method. In this work, a new solution with the finite difference Jacobian based NK (DJNK) method is proposed, where the Jacobian matrix is calculated by finite difference approximation instead of the analytical form. Moreover, DJNK is further improved to form ...

Physic nut (Jatropha curcas L.) is a potential feedstock for biofuel production because Jatropha oil is highly suitable for the production of the biodiesel and bio-jet fuels. However, Jatropha exhibits low seed yield as a result of unreliable and poor flowering. FLOWERING LOCUS T (FT) –like genes are important flowering regulators in higher plants. To date, the flowering genes in Jatropha have not yet been identified or characterized. To better understand the genetic control of flowering in Jatropha, ...

Jatropha curcas seeds are an excellent biofuel feedstock, but seed yields of Jatropha are limited by its poor flowering and fruiting ability. Thus, identifying genes controlling flowering is critical for genetic improvement of seed yield. We isolated the JcLFY, a Jatropha ortholog of Arabidopsis thaliana LEAFY (LFY), and identified JcLFY function by overexpressing it in Arabidopsis and Jatropha. JcLFY is expressed in Jatropha inflorescence buds, flower buds, and carpels, with highest expression in ...

Objective: Emerging evidence shows that high blood pressure (BP) level even below 140/90 mmHg during pregnancy is associated with increased risk for maternal and infant complications. The meta-analysis evaluated the associations between prehypertension (BP 120-139/80-89 mmHg) during pregnancy and the risk of small for gestational age (SGA), as well as the impact of prehypertension on birth weight (BW).Methods: Databases (PubMed, Embase, and Cochrane Library) were searched for cohort studies with data ...

Multidrug resistance (MDR) is one of the leading causes of the failure of cancer chemotherapy and mainly attributed to the overexpression of drug efflux transporters in cancer cells, which is dependent on adenosine triphosphate (ATP). To overcome this phenomenon, herein, a mitochondrial-directed pH-sensitive polyvinyl alcohol (PVA) nanogel incorporating the hexokinase inhibitor lonidamine (LND) and the chemotherapeutic drug paclitaxel (PTX) was developed to restore the activity of PTX and synergistically ...
