Current optimization methods for microgrid scheduling face issues such as insufficient precision in energy distribution, high operational costs, and inefficiency. In response to these challenges, an optimization scheduling method for multi-energy microgrids based on the QUBO (Quadratic Unconstrained Binary Optimization) quantum computing model is proposed in this paper, alongside a discretization approach based on a grid partitioning strategy. To validate the feasibility of addressing microgrid optimization scheduling problems in a quantum computing environment, a QUBO model is constructed and simulation studies are conducted in the qbsolv environment provided by D-Wave. The results indicate that operational costs are significantly reduced with an increase in the number of grids, particularly a reduction of 4.52% when the number of grids increases from five to ten. This method not only effectively enhances the precision of electricity supply and energy utilization efficiency but also reduces unnecessary electrical waste and economic costs. © Beijing Paike Culture Commu.

With the further development of "double high" characteristics of power system, the traditional stability problem dominated by synchronous generator has gradually evolved into a new stability problem dominated by power electronic equipment control. In addition, different types of failure problems can occur in wind power systems. In order to achieve multi-objective coordinated and stable operation of high proportion wind power system, a damping control method with parameters tuning is proposed, which includes the design of filtering link and proportional amplification link. Among them, the key parameters of the proportional link are adjusted. Finally, the feasibility of the proposed control method is verified by simulation tests. © Beijing Paike Culture Commu.

Consumption of broccoli contributes to the maintenance of glucose homeostasis due to its high dietary fiber. Nevertheless, the effects of soluble dietary fiber from broccoli stem and leaf (B-SDF) on debate-related metabolic syndrome and its hypoglycemic mechanism remain ambiguous. This study is aimed at exploring the beneficial influences of B-SDF on ameliorating metabolic syndrome and reveal the hypoglycemic mechanism by gut microbiota composition. Administration with B-SDF mitigated various metabolic syndromes in mice induced by high-fat diet (HFD), including weight gain, organ indexes, glucose intolerance, elevated serum lipid levels (TC, TG, and HDL-c) and oxidative stress (SOD and MDA), as well as renal dysfunction (Urea, Cr, and UA). B-SDF intervention attenuated liver damage and lipid accumulation in mice. Furthermore, gut microbiota dysbiosis in HFD mice was ameliorated by B-SDF supplementation, emphasizing its critical role in the regulation of metabolic disorders. B-SDF intake significantly reduced the proportion of Firmicutes and increased the abundance of Bacteroidetes (p © 2025, The Authors. All rights reserved.

This study is aimed at exploring the beneficial influences of B-SDF on ameliorating metabolic syndrome and revealing the hypoglycemic mechanism by gut microbiota composition. Administration with B-SDF mitigated various metabolic syndromes in mice induced by high-fat diet (HFD), including weight gain, glucose intolerance, oxidative stress (superoxide dismutase and malondialdehyde), renal dysfunction (urea, creatinine, and uric acid), liver damage and lipid accumulation. Furthermore, gut microbiota dysbiosis in HFD mice was ameliorated by B-SDF supplementation, which significantly reduced the proportion of Firmicutes and increased the abundance of Bacteroidetes (p < 0.05) compared with the HFD group. The gut microbiota composition was reshaped by elevating the level of Eubacterium and decreasing the numbers of Lachnospiraceae NK4A136 and Alistipes in HFD mice. These novel findings demonstrate the potential of B-SDF as a valuable ingredient in prebiotics or functional foods for diabetes management. © 2025 Elsevier Ltd

Ultrasound, a nonthermal processing technology, preserves food's nutritional value and organoleptic properties while inactivating microbes and enzymes. Despite minimal changes in volatile compounds during processing, recent studies have shown that ultrasound can accelerate the generation of flavor compounds by enhancing cavitation-induced chemical reactions. This process alters volatile flavor profiles and improves flavor perception through the breakdown of fats and proteins. This work explores the effects of ultrasound on volatile compounds, starting with the principles linking ultrasound treatment to volatile evolution. It then summarizes the volatile fingerprint responses across key food categories and discusses the mechanisms driving these changes. Finally, the potential applications of ultrasound-induced flavor modifications in food processing are analyzed and explored. A comprehensive investigation into the influence of ultrasound on food volatiles provides valuable insights for food processing practices, positioning ultrasonic irradiation as a promising tool for tailoring volatile flavor features of industrially manufactured food matrices. © 2025 Elsevier Ltd

Performance Enhancement of Multiuser Passive Time Reversal Communication Based on Space-Time Block Coding

Reliable, with high data rate, acoustic communication in time-valTing, multipath shallow water environment is a hot research topic recently. Passive time reversal communication has shown promising results in improvement of the system performance. In multiuser environment, the system performance is significantly degraded due to the interference among different users. Passive time reversal can reduce such interference by minimizing the cross-correlated version of channel impulse response among users, which can be realized by the well-separated users in depth. But this method also has its shortcomings, even with the absence of relative motion, the minimization sometimes may be impossible because of the time-varying environment. Therefore in order to avoid the limitation of minimizing the cross-correlated channel function, an approach of passive time reversal based on space-time block coding （STBC） is presented in this paper. In addition, a single channel equalizer is used as a pest processing technique to reduce the residual symbol interference. Experimental results at 13 kHz with 2 kHz bandwidth demonstrate that this method has better performance to decrease bit error rate and improve signal to noise ratio, compared with passive time reversal alone or passive time reversal combined with equalization.

An oil soluble rare earth compound, samarium isooctoxyborate, was synthesized and used as an antiwear and extreme pressure additive for lubricating oils. Its tribological performances were evaluated with a four ball machine and a ring on block rig. In addition, surface analyses with Auger electron spectroscopy and X ray photoelectron spectroscopy were also conducted to study the surface film formed by the additive under boundary lubrication conditions. The test results show that the additive exhibits good friction reducing ability, good antiwear property and excellent extreme pressure performance. Surface analyses further disclose the coexistence of organic film, oxidation film and permeating film on the rubbing surface, which contributed to improve the tribological properties of the base oil.

This paper adopts the program Ansys and its secondary exploit platform tools to construct three-dimensional model to simulate the destroy process of cave depot. The method that damage surface and yield surface are dealt separately, and dispersion model is forward to simulate flaws. And the results of numerical simulation have been debated to find the laws of flaws growth and distribution with increasing of explosion pressure. It can be found that with the the linear increase of explosion pressure, flaws and distribution regions of flaws grow and expand. Tension flaws are precede to shear flaws. Flaws regions appear in the order, namely, the center of the arch--arch foot--flaws in the center arch propagation-flaws in other else regions propagation. The research result has important value for online monitor, maintain and reinforce of cave depot. And the technology that has been forwarded in this paper also supplies for the numerical simulation researcher. © (2013) Trans Tech Publications, Switzerland.

In order to numerical simulate the transition process from continua to discontinua and even to structural collapse,the collapse of bricklaying arch built by two-layer stone material is analyzed based on the deformable distinct element method(DEM). The simulation results are consistent with that of experiment. The research results shows that not only the load-displacement response of the arch under uniform fracture energy can be appropriately predicted through the method, but also the collapse behavior when the system partially or completely reaches failure can also be simulated. © (2013) Trans Tech Publications, Switzerland.

Compact microstructure of goose myofibrillar proteins (MP) negatively affects texture and flavor properties, as thick, large myofibers result in lower tenderness and limited capacity to absorb water and flavor compounds. This study proposes a strategy to regulate the MP microstructure and physicochemical qualities of conditioned meat by altering protonation signaling during pulsed electric field (PEF) processing. The results demonstrated that enhanced protonation during PEF significantly improved the meat quality. MP solubility increased by 4.91–9.03 %, while particle size decreased by 32.56–52.85 % compared to PEF alone or deprotonated conditions, attributed to protonation enhanced dissociation-depolymerization and unfolding of MP. Histological observations via the staining and electron microscopy revealed that enhanced protonation disrupted the muscle fiber arrangement and MP network. The tertiary structure of MP was altered, exposing internal hydrophobic regions and releasing volatile flavor compounds, which increased the headspace concentration of volatile compounds in goose meat during prolonged PEF treatment, thus helping enhance the complexity of meat flavor and the perception of characteristic aromas. These results demonstrated the dual effects of enhanced protonation and deprotonation during PEF treatments, which synergistically drove structural and functional changes in MP. The study validated the feasibility of altering protonation signaling during PEF to modulate meat processing characteristics. © 2025 Elsevier B.V.
