γ-l-Glutamyl-S-allyl-l-cysteine (GSAC) is renowned for its flavor-modifying effects and beneficial biological activities. However, the level of GSAC decreases significantly during processing black garlic, pathways degradation products resulting from this decline remain unclear. To investigate potential transformation mechanisms in simulation systems thermal decomposition, Maillard reactions, enzymatic hydrolysis were established. In addition to fructose, a total 6 identified confirmed....

In this paper, we address the problem of coordinated beamforming design for multi-cell multiple input single output (MISO) downlink system subject to per-BS power constraints. The objective is taken as maximization minimum signal-to-interference plus noise ratio (SINR), while a complete analysis duality between and virtual uplink optimization problems provided. A hierarchical iterative scheme proposed solve problem, whose solution then converted derive one problem. algorithm proved converge...

Pyrethroid pesticides are widely used on tea plants, and their residues of high frequency concentration have received great attention. Until recently, the typical metabolites pyrethroid in were unknown. Herein, a modified “quick, easy, cheap, effective, rugged safe” (QuEChERS) method for determination three tea, using ultra performance liquid chromatography tandem mass spectrometry, was developed. The mixture florisil, octadecylsilane, graphite carbon black employed as QuEChERS adsorbents. A...

Anemia and weaning stress are important factors affecting piglet growth performance. Spinach extract licorice have been used to improve anemia antioxidant capacity, respectively. However, whether they synergistic effects has not reported. To evaluate the of mixed spinach on performance, serum biochemistry, gut microbiota in weaned piglets, a total 160 piglets were randomly allotted four treatments with replications 10 each. The as follows: control (CON) group (basal diet), (SE) diet + 1.5...

The residues of 16 phthalate esters (PAEs) in fresh tea leaves and made were determined via gas chromatography–tandem mass spectrometry to study their distribution degradation characteristics during planting processing. Five PAEs detected all leaves, higher concentrations mature leaves. ranged from 69.7 2244.0 μg/kg. degradative percentages ∑5PAEs green manufacturing 61 63% significantly influenced by the drying process. transfer rates PAEs-D4 5.2 100.6%. with a high water solubility showed...

Storage is important for the garlic cloves industry because it critical to enabling a year-round supply. This study aimed investigate changes in biochemical and metabolic profiles terms of different temperatures cultivars during storage using nontargeted targeted metabolomics. The results showed that times were factors affecting composition metabolite content cloves. In detail, profiling changed significantly at 22 °C, which was mainly related sprouting. Furthermore, γ-glutamyl peptide...

Asparagus is a popular vegetable and traditional medicine consumed worldwide due to its health benefits. The quality of asparagus, mainly attributed small components like flavonoids steroid, quite differential as result different environments maturities. However, the accumulation pattern regulatory mechanism metabolites in asparagus remain unclear so far. Herein, widely targeted metabolomics analysis was employed study chemical composition variances four including three green maturities one...

Abstract Asparagus, a vital economic contributor, is well‐liked vegetable grown around the globe, and some secondary metabolites in its spear are beneficial to human health. Asparagus spears possess significant quantity of nutrients phytochemicals; however, difference these chemical compositions among various varieties has not been sufficiently studied. This work aimed detect 30 asparagus assess them by principal component analysis (PCA). The results showed that contents varied varieties....

Residues of polycyclic aromatic hydrocarbons (PAHs) in green tea and infusion were determined using gas chromatography-tandem mass spectrometry to study their dissipation pattern during processing infusion. Concentration evaporation PAHs the key factors affecting PAH residue content product intermediates tea. residues leaves increased by 2.4–3.1 times manufacture electric heating model. After correction dry weight, concentrations decreased 33.5–48.4% because evaporation. Moreover, spreading...

Garlic-specialized metabolites contribute to both spicy flavor and healthy function of garlic. Their accumulation pattern regulatory mechanism vary greatly at different environments maturities. Herein, metabolomics models were built evaluate predict the quality chemical composition variances four garlic varieties in two regions six growth stages. A total 91 identified, their during three Shandong was similar but obviously distinct from that planted Heilongjiang. Active metabolism for...

In this work, a novel two-dimensional (2D) porous nanostructure is constructed upon air/water interfacial assembly of 12-crown-ether-4-incorporated double-decker phthalocyanine (Pc2). The combination the good electroconductivity and great surface area structure endows assembled film with excellent chemical sensing property for ascorbic acid (AA). low limit detection can be 0.15 μM large linear concentration range strong anti-interfering ability, which comparable to best results...

The accumulation, distribution, and transportation of nutrients in different tissues garlic during growth are unclear. Thereby, five (leaf, pseudostem, bulb wrapper, clove skin, clove) collected at 7 weeks were subjected to metabolomics analysis. A total 84 biomarkers identified plant growth. Most organosulfur compounds, amino acids, dipeptides upregulated the clove, while a reversed trend was observed other tissues. In addition, nucleotides alkaloids increased because senescence last 2...

Classification of modulation types faces a problem low SNR in conditions where Low Probability Interception signals are used. A novel feature vector extraction algorithm fit for LPI communication is presented, which generated by autonomously cropping the energy from Time-Frequency images. Multi-Layered Perceptron adopted as classification decision parts. Probabilities correct obtained via computer simulation. The results show that scheme proposed this paper has promising performance conditions.

C-type lectins (CTLs) are a class of proteins containing carbohydrate recognition domains (CRDs), which characteristic modules that recognize various glycoconjugates and function primarily in immunity. CTLs have been reported to affect growth development positively regulate innate immunity Tribolium castaneum. However, the regulatory mechanisms TcCTL16 still unclear. Here, spatiotemporal analyses displayed was highly expressed late pupae early adults. RNA interference larvae shortened their...

In this paper, the synchronization problem of Chen systems with time-varying delays is discussed based on stability theory time-delay systems.
