发酵食品具有特殊的风味和营养,含有多种生物活性物质。超声技术是一种非热处理技术,已被证实在食品中具有杀菌,提高活性产物产量,改变食物大分子性质等作用。目前缺乏超声技术在发酵食品处理中的系统性讨论。本文概述超声技术对不同发酵食品在发酵和贮藏中微生物以及发酵食品品质影响的研究进展。超声对发酵食品的影响效果取决于超声处理参数、发酵食品自身特点和所含微生物种类。不同条件超声处理通过改变微生物细胞结构、基因和代谢等机制,既可以抑制有害微生物生长,保证发酵食品安全性,也可以调控益生菌菌株活性,提高发酵食品营养价值。超声处理还能够提高发酵速率,缩短发酵时间,控制发酵过程,减少过度发酵,增加发酵食品中生物活性物质含量,赋予发酵食品营养保健功效等作用。本文可为超声技术在传统发酵食品工业化生产及品质提升中的应用提供参考。

Reinforcement learning-based traffic signal control systems (RlTSC) can enhance dynamic adaptability, save vehicle travelling timeand promote intersection capacity. However, the existing RlTSC methods do not consider the driver’s response time requirement, sothe systems often face efficiency limitations and implementation *** propose the advance decision-making reinforcementlearning traffic signal control (AD-RlTSC) algorithm to improve traffic efficiency while ensuring safety in mixed traffic ***, the relationship between the intersection perception range and the signal control period is established and the trust region state(TRS) is proposed. Then, the scalable state matrix is dynamically adjusted to decide the future signal light status. The decision will bedisplayed to the human-driven vehicles (HDVs) through the bi-countdown timer mechanism and sent to the nearby connected automatedvehicles (CAVs) using the wireless network rather than be executed immediately. HDVs and CAVs optimize the driving speedbased on the remaining green (or red) time. Besides, the Double Dueling Deep Q-learning network algorithm is used for reinforcementlearning training;a standardized reward is proposed to enhance the performance of intersection control and prioritized experiencereplay is adopted to improve sample utilization. The experimental results on vehicle micro-behaviour and traffic macro-efficiencyshowed that the proposed AD-RlTSC algorithm can simultaneously improve both traffic efficiency and traffic flow stability.

The California Simulation of Evapotranspiration of Applied Water （CaI-SIMETAW） model is a new tool developed by the California Department of Water Resources and the University of California, Davis to perform daily soil water balance and determine crop evapotranspiration （ETo）, evapotranspiration of applied water （ETaw）, and applied water （AW） for use in California water resources planning. ETaw is a seasonal estimate of the water needed to irrigate a crop assuming 100% irrigation efficiency. The model accounts for soils, crop coefficients, rooting depths, seepage, etc. that influence crop water balance. It provides spatial soil and climate information and it uses historical crop and land-use category information to provide seasonal water balance estimates by combinations of detailed analysis unit and county （DAU/County） over Califomia. The result is a large data base of ETc and ETaw that will be used to update information in the new California Water Plan （CWP）. The application uses the daily climate data, i.e., maximum （Tx） and minimum （Tn） temperature and precipitation （Pcp）, which were derived from monthly USDA-nRCS PRISM data （PRISM Group 2011） and daily US national Climate Data Center （nCDC） climate station data to cover California on a 4 kmx4 km change grid spacing. The application uses daily weather data to determine reference evapotranspiration （ETo）, using the Hargreaves-Samani （HS） equation （Hargreaves and Samani 1982, 1985）. Because the HS equation is based on temperature only, ETo from the HS equation were compared with CIMIS ETo at the same locations using available CIMIS data to determine correction factors to estimate CIMIS ETo from the HS ETo to account for spatial climate differences. CaI-SIMETAW also employs near real-time reference evapotranspiration （ETo） information from Spatial CIMIS, which is a model that combines weather station data and remote sensing to provide a grid of ETo information.

拟单层覆盖粗糙集是一种匹配集值信息系统且有高质量和高效率的粗糙集模型。拟单层覆盖近似集的计算过程中存在大量计算密集且逻辑简单的运算,为此,提出拟单层覆盖近似集的矩阵化表示方法,以利用图形处理器(GPU)强大的计算性能加速计算过程。为了实现这一目标,使用布尔矩阵表示拟单层覆盖近似空间中的元素,引入与集合运算对应的布尔矩阵算子,提出拟单层覆盖粗糙近似集(DE、DA、DE0与DA0)的矩阵表示,并设计矩阵化拟单层覆盖近似集算法(M_SMC)。同时,相应的定理证明了拟单层覆盖近似集的矩阵表示形式与原始定义的等价性。然而,M_SMC运行过程中出现了矩阵存储和计算步骤的内存消耗过多问题。为了将算法部署到显存有限的GPU上,优化矩阵存储和计算步骤,提出分批处理的矩阵化拟单层覆盖近似集算法(BM_SMC)。在10个数据集上的实验结果表明,融合GPU的BM_SMC算法与单纯使用中央处理器(CPU)的BM_SMC算法相比计算效率提高2.16~11.3倍,BM_SMC算法可以在有限的存储空间条件下充分利用GPU,能够有效地提高拟单层覆盖近似集的计算效率。

AIM: To evaluate the effect of femtosecond laser-assisted lens surgery(FlAlS;cataract surgery or refractive lens exchange) on the structure of the optic nerve head and the ***: This prospective longitudinal study included healthy eyes undergoing FlAlS. Eyes with glaucoma or any other ocular disease that could alter optical coherence tomography results were excluded. Retinal nerve fiber layer(RnFl), Bruch’s membrane opening-minimum rim width(BMO-MRW) and macular thickness(MT) were measured preoperatively, 1 and 6 mo after surgery using spectral-domain optical coherence tomography(SD-OCT). Changes between preoperative and postoperative values were ***: A total of 87 eyes of 46 patients were included in this study. Preoperative RnFl, BMO-MRW and MT in microns(μm) were 100.77±10.39, 330.31±49.99 and 276.30±33.39, respectively. Postoperative RnFl, BMO-MRW and MT were 104.74±11.55, 348.32±54.05 and 279.83±22.65 1 mo after surgery and 102.93±11.17, 343.11±53.4 and 278.90±22.19 6 mo after surgery, respectively;which equals an increase of 3.93%, 5.45% and 1.27%,respectively, 1 mo after surgery, and 2.14%, 3.87% and 0.94% 6 mo after surgery. The differences between the preoperative and the postoperative RnFl and BMO-MRW values were statistically significant(Png MT values, there were not statistically significant differences(P=0.26).COnClUSIOn: Our study suggests that FlAlS does not have a negative impact on the structural status of the optic nerve head in healthy eyes, assessed by SD-OCT. There is a slight increase in the values of RnFl, BMO-MRW and MT 1 mo and 6 mo after surgery.
