Anthocyanins and flavones are important pigments responsible for the coloration of fruits. Mulberry fruit is rich in anthocyanins flavonols, which have multiple uses traditional Chinese medicine. The antinociceptive antibacterial activities total flavonoids (TF) from black mulberry (MnTF, TF Morus nigra) non-black (MmTF, mongolica; MazTF, alba ‘Zhenzhubai’) fruits were studied. MnTF was (11.3 mg/g) flavonols (0.7 identified by ultra-performance liquid chromatography–tunable ultraviolet/mass...

To endow nanofibers with the desirable antibacterial and mechanical properties, a facile strategy using Pickering emulsion (PE) electrospinning is proposed to prepare functional core/shell structure for first time. The water‐in‐oil (W/O) stabilized by oleic acid (OA)‐coated magnetite iron oxide nanoparticles (OA‐MIONs) comprised of aqueous vancomycin hydrochloride (Van) solution poly(lactic acid) (PLA) solution. electrospun Van/OA‐MIONs‐PLA confirmed scanning electron microscopy transmission...

Cull cow meat myofibrillar protein (CCMP) filled with carboxymethylated cellulose nanofibrils (cCNF) was initially characterized to study the effect of cCNF on gelation properties CCMP. Before heating, increased degree substitution (DS) cCNF, ζ-potential and hydrophobicity CCMP-cCNF solution at same filler mass fractions (ϕm). During process shortened after adding especially samples high DS. After lower DS led liquid loss gels, amplified ϕm cCNF. Similarly, network structure low more compact...

Excavators are one of the most frequently used pieces equipment in large-scale construction projects. They closely related to speed and total cost entire project. Therefore, it is very important effectively monitor their operating status detect abnormal conditions. Previous research work was mainly based on expert systems traditional statistical models excavator anomalies. However, these methods not particularly suitable for modern sophisticated excavators. In this paper, we take first step...

Heart rate is one of the four vital signs that has most obvious response to changes in human health status. This paper applied a non-contact heart detection method based on image Photoplethysmography (IPPG). Firstly, RGB color images channels were collected by ordinary general cameras, and region interest (ROI) was located face recognition. Then KLT algorithm used calculate target offset interest, ROI modified. After that, channel signals are converted Lab space extract Blood Volume Pulse...

Abstract A shape‐stabilized composite phase change material (SS‐CPCM) with paraffin (PA) and biological porous carbon (BPC) was prepared. Freeze‐dried biological‐cellulose include abandoned pomelo peel (APP) tangerine (ATP) were carbonized in vacuum at 800 °C to obtain BPC be used as a matrix prevent PA leakage enhance thermal conductivity. impregnation process utilized the SS‐CPCM. Scanning electron microscopy showed that (carbonized APP is subsequently referred BPC1 ATP BPC2) has porous,...

Errors are caused by wall reflection and noise in the visible light indoor positioning system. Some algorithms based on fingerprint compared through simulation. An improved algorithm that combines K-Nearest Neighbor Bayesian theory is proposed. Firstly, several grid points which close to receiver's position selected KNN algorithm, then posterior probability calculated algorithm. The point with largest estimated position. simplifies improves accuracy of an average error 0.27m.

Abiotic stress, especially drought poses a significant threat to terrestrial plant growth, development, and productivity. Although mulberry has great genetic diversity extensive stress-tolerant traits in agroforestry systems, only few reports offer preliminary insight into the biochemical responses of leaves under conditions. In this study, we performed comparative metabolomic transcriptomic analysis on “drooping mulberry” (Morus alba var. pendula Dippel) PEG-6000-simulated stress. Our...

In recent years, much speech separation research has focused primarily on improving model performance. However, for low-latency processing systems, high efficiency is equally important. Therefore, we propose a with significantly reduced parameters and computational costs: Time-frequency Interleaved Gain Extraction Reconstruction network (TIGER). TIGER leverages prior knowledge to divide frequency bands compresses information. We employ multi-scale selective attention module extract...

Visible light radiated from light-emitting diodes is used to estimate the position of receiver in a positioning system indoors. Wall reflection and noise are inevitable, which result an error visible indoor system. Some algorithms based on fingerprint compared through simulation. An improved algorithm Bayesian theory proposed. After using Gaussian filter, several grid points that close each other selected be cluster, then posterior probability cluster calculated by algorithm. The with...

To evaluate the noise of a diesel engine and provide basis for next step reduction, boundary element model has been built finite software is used to analyze engine. Surface vibration velocity distribution, radiation spectrum, sound pressure distribution total level are calculated. The calculation results obtained show that most representative three points peak SPL (sound level) 500Hz, 1200Hz 1950Hz; 108.99dB; main sources oil pan, gear chamber cover flywheel housing, these parts should be...

Abstract Effects of minerals on the conformational changes protoxin isolated from Bacillus thuringiensis were investigated by circular dichroism and fluorescence spectroscopy. Contact with attapulgite, montmorillonite kaolinite for 3 h resulted in no significant spectra a slight decrease intensity. There after desorption comparison to native protoxin. The intensity protoxins desorbed retained 77.5, 63.7 60.4% protoxin, respectively. influential extent secondary structure was higher than that...

The membrane characteristics of capsules composed sodium cellulose sulfate(NaCS)and poly[dimethyl (diallyl)ammonium chloride](PDMDAAC)were investigated under the condition introducing other molecules.The small molecules,soluble polymers,soluble polyions,and salts molecule were individually added into polyanion(NaCS)solution to check their effects on capsule formation.The thickness and mechanical intensity studied different concentration additives.Meanwhile additives viscosity zeta potential...
