An improved differential evolution algorithm for multi-modal multi-objective optimization
MODE is widely used for solving MMOPs, which are named as MMEAs. First, the definition of DE algorithm and APC is presented. The corresponding definitions, including local PS, global PS, local PF and global PF, can be referred to Li et al. (2022). In a typical MMOP, only one global PF maps to either a single PS or multiple global PSs, as shown in Fig. 1. However, in an MMOP with a local Pareto front (MMOPL), there exist local PFs and only one global PF, as depicted in Fig. 2.

An Uncertain Sandwich Impulsive Control System with Impulsive Time Windows
Abstract : In this paper, we formulate a new system, named the uncertain sandwich impulsive control system with impulsive time windows. The presented system shows that the linear entry matrix of the system is indeterminate. We first investigate the exponential stability of the considered system by linear matrix inequalities (LMIs) and inequalities techniques, then extend the considered system to a more general one and further study the stability of the general system.
Experimental Studies of Thermal Conductivity of Three Biodiesel Compounds: Methyl Pentanoate, Methyl Octanoate, and Methyl Decanoate
Biodiesels are mainly composed of fatty acid methyl esters (FAMEs). Before using them for industrial applications, it is essential to study the thermophysical properties of FAMEs. Thermal conductivity of fuels is required in many processes, such as design of heat exchangers and biodiesel combustion modeling.
Water management by hierarchical structure for highly efficient solar water evaporation
Water management by hierarchical structure for highly efficient solar water evaporation Solar water evaporation is a sustainable and efficient way to produce freshwater. Seeking highly efficient photothermal materials is an important step to achieve high evaporation rate. However, the effect of water interfacial area is rarely paying attention although a few reports demonstrated high evaporation rate from micro-/nanostructure device.

The regulatory effects of phytosterol esters (PSEs) on gut flora and fecal metabolites in rats with NAFLD
The regulatory effects of phytosterol esters (PSEs) on gut flora and fecal metabolites in rats with NAFLD Recent studies have shown that the occurrence and progression of nonalcoholic fatty liver disease (NAFLD) can be aggravated by dysregulation of intestinal flora. We previously found that phytosterol esters (PSEs) could effectively prevent the progression of NAFLD. Here, we further investigated the regulatory effect that PSEs have on gut flora and faecal metabolites in rats with NAFLD.
Purposely Constructing Direct Z-scheme Photocatalyst by Photo-deposition Technique
Purposely Constructing Direct Z-scheme Photocatalyst by Photo-deposition Technique Constructing Z-scheme type photocatalyst is the preference for achieving efficient photocatalyst because its high oxidative and reductive capability of composites catalyst. Direct Z-scheme (DZS) is composed of two semiconductors contacted each other which eliminate the disadvantage of electron mediate in liquid and solid state Z-scheme. However, it is a big challenge to constructing the DZS on purpose.
Self-floating nanostructural Ni-NiOx/Ni foam for solar thermal water evaporation
Self-floating nanostructural Ni-NiOx/Ni foam for solar thermal water evaporation Dandan Wu, Dan Qu, Wenshuai Jiang, Ge Chen, Li An, Chunqiang Zhuang and Zaicheng Sun Abstract Solar thermal water evaporation is a clean, sustainable and energy-saving way to generate fresh water compared with the traditional way. Electro-blacks, for example, nickel black have been commercialized for the solar water heater.
Se & N Co-doped Carbon Dots for High-performance Fluorescence Imaging Agent of Angiography
Both long wavelength excitation and emission are highly desired for fluorescent carbon dots in the bio-related applications. According to semiconductor theory, heteroatom doping is an effective way to tune the band gap of semiconductor. In this work, we developed an exceedingly simple and mild one-pot method to synthesize selenium and nitrogen co-doped carbon dots (Se&N-CDs) by using low cost citric acid, ethane diamine and selenium powder as the starting materials.
Inhibition of miR-200c Restores Endothelial Function in Diabetic Mice Through Suppression of COX-2
Endothelial dysfunction plays a crucial role in the development of diabetic vasculopathy. Our initial quantitative PCR results showed an increased miR-200c expression in arteries from diabetic mice and patients with diabetes. However, whether miR-200c is involved in diabetic endothelial dysfunction is unknown.
