菲律宾经济的增长在很大程度上依赖于微型、小型和中型企业(ms.E),其占全部注册企业比例高达99%。微型、小型和中型企业(ms.E)通过创造新的就业机会、生产新的产品和服务以及激活市场竞争活力,在支持国民经济发展方面发挥着至关重要的作用。新冠疫情爆发使全球经济和社会遭到极大破坏,造成了极端的市场不稳定和波动,对商业和贸易产生了重大的负面影响。大多数中小微企业集中于传统产业,创新水平和抗风险能力较差,在新冠疫情冲击下,深受客户购物习惯和行为发生重大变化的新商业趋势的影响,甚至大量企业面临倒闭。然而,传统产业依然具有较强的民生需要和存在的价值。因此,在后疫情时代,深入探讨传统产业中小微企业面临的新机遇与挑战,探索中小微企业的创新发展战略,对企业寻求新的生机,推动就业和经济稳定发展具有重要意义。本文选取本人所在区域可调研的BC企业(为企业保密名字采用缩写)开展中小微企业发展战略案例研究。本人所在区域为菲律宾丹轆市重要的家具销售市场,BC企业为当地具有典型代表型家具销售企业。本文对BC企业实际业务内容、进货渠道、销售水平、财务数据和顾客等内部经营情况进行深入调研。采用PEST模型分析全球和菲律宾总体政治、经济、社会和技术等宏观环境,采用波特五力模型分析BC企业所面临的市场和行业环境,尤其是新冠疫情爆发以来出现的新的市场变化。结合企业面临的外部机遇与挑战,内部优势和劣势,对BC企业展开SWOT分析,并制定BC企业的短期、中期和长期发展战略。综合来看,BC企业在前期多年的经营发展过程中,形成了较为合理的组织结构,建立了具有竞争力的进货渠道,家具销售品种丰富,占据了较为良好的销售地段。但疫情爆发以来,宏观经济不景气,消费者购买能力受到影响,线下购买行为也减少,当地家具市场总体销售下滑。BC企业面临较为严重的销售业绩不佳,利润率逐月下降,甚至遭受损失。针对企业内外部环境发生的新变化,BC企业必须适应后疫情时代下新常态。为此,本文为期制定了“1261”发展战略。即打造一家创新型家具服务企业,构建线上线下双销售渠道,主攻六大家具装修风格,提供家具设计、制造、安装、售后一条龙服务。紧抓消费升级机遇提升服务水平,紧抓信息科技发展拓展线上销售渠道,以促使BC企业在激烈的家具竞争市场利用企业原有优势和新的发展机遇,形成超越竞争对手的特色比较优势,提高整体绩效。

Prediction of bacteria-carrying particle （BCP） dispersion and particle distribution released from staffmem- bers in an operating room （OR） is very important for creating and sustaining a safe indoor environment. Postoperative wound infections cause significant morbidity and mortality, and contribute to increased hospitalization time. Increasing the number of personnel within the OR disrupts the ventilation airflow pattern and causes enhanced contamination risk in the area of an open wound. Whether the amount of staffwithin the OR influences the BCP distribution in the surgical zone has rarely been investigated. This study was conducted to explore the influence of the number of personnel in the OR on the airflow field and the BCP distribution. This was performed by applying a numerical calculation to map the airflow field and Lagrangian particle tracking （LPT） for the BCP phase. The results are reported both for active sampling and passive monitoring approaches. Not surprisingly, a growing trend in the BCP concentration （cfu/ms. was observed as the amount of staff in the OR increased. Passive sampling shows unpredictable results due to the sedimentation rate, especially for small particles （5-10 i^m）. Risk factors for surgical site infections （SSls） must be well understood to develop more effective prevention programs.

At present,most researches on the critical rainfall threshold of debris flow initiation use a linear model obtained through *** relatively weak fault tolerance,this method not only ignores nonlinear effects but also is susceptible to singular noise samples,which makes it difficult to characterize the true quantization relationship of the rainfall ***,the early warning threshold determined by statistical parameters is susceptible to negative samples(samples where no debris flow has occurred),which leads to uncertainty in the reliability of the early warning results by the regression *** overcome the above limitations,this study develops a data-driven multiobjective evolutionary optimization method that combines an artificial neural network(ann)and a multiobjective evolutionary optimization implemented by particle swarm optimization(PSO).Firstly,the Pareto optimality method is used to represent the nonlinear and conflicting critical thresholds for the rainfall intensity I and the rainfall duration *** ann is used to construct a dual-target(dual-task)predictive surrogate model,and then a PSO-based multiobjective evolutionary optimization algorithm is applied to train the ann and stochastically search the trained ann for obtaining the Pareto front of the I-D surrogate prediction model,which is intended to overcome the limitations of the existing linear regression-based threshold ***,a double early warning curve model that can effectively control the false alarm rate and negative alarm rate of hazard warnings are proposed based on the decision space and target space *** study provides theoretical guidance for the early warning and forecasting of debris flows and has strong applicability.

This paper proposes the use of time-frequency and wavelet transform features for emotion recognition via EEG signals. The proposed experiment has been carefully designed with EEG electrodes placed at FP1 and FP2 and using images provided by the Affective Picture System (IAP), which was developed by the University of Florida. A total of two time-domain features, two frequen-cy-domain features, as well as discrete wavelet transform coefficients have been studied using Artificial Neural Network (ann) as the classifier, and the best combination of these features has been determined. Using the data collected, the best detection accuracy achievable by the proposed schemed is about 81.8%.

β-苯乙胺(PEA)是一种重要的有机合成中间体,在PEA生产过程中,最终的生成物中常常为含有氯化钠(NaCl)、氢氧化钠(NaOH)和PEA三者的混合物。因此,对NaCl,NaOH,PEA和混合物种类进行鉴别,有利于PEA的合成以及定性检测,需建立紫外光谱快速鉴别NaCl,NaOH,PEA和混合物种类的方法。利用紫外光谱法分别测量了NaCl,NaOH,PEA和混合物在190~400 nm范围的吸收光谱。首先,采用偏最小二乘法(PLS)提取紫外光谱的主成分信息,用少数的主成分信息取代原始变量,减少模型的复杂度。用PLS提取NaCl,NaOH和PEA在前三个主成分空间中得分向量值的分布。可知NaCl,NaOH和PEA前三个主成分累计贡献率分别是96.64%,99.44%和99.95%。因此,NaCl、NaOH和PEA的前三个主成分基本包含了大部分的光谱信息。其次,用获得的三个主成分作为输入变量,采用线性判别分析(LDA),Sigmoid SVM,RBF-SVM,RBF-ann,BP-ann和人工蜂群(ABC)优化神经网络(ABC-BP-ann)等模式识别方法对NaCl,NaOH和PEA种类进行判别,获得总的敏感性分别为95.6%,95.6%,95.9%,95.8%,96.9%和99.6%。由于NaCl和NaOH特征吸收峰很相似,主成分得分向量会出现重叠现象,导致NaCl和NaOH的种类鉴别出现误判。通过对比六种分类方法,可知ABC-BP-ann效果最优,BP-ann次之,RBF-SVM和RBF-ann结果相似,但比BP-ann稍差,LDA和Sigmoid-SVM效果最差。最后,配制7种不同摩尔分数的混合物(混合物摩尔分数是指PEA物质的量占混合物总物质的量百分比),浓度范围为0%mol·L^-1~60%mol·L^-1,然后采用RBF-SVM,BP-ann和ABC-BP-ann三种方法对混合物种类进行判别。从敏感性和特异性结果可以得知,ABC-BP-ann分类效果最好,BP-ann次之,RBF-SVM分类效果最差,由混合物得到的结果与单组分的结果相一致。结果表明,紫外光谱结合ABC-BP-ann模式识别方法可以成功区分NaCl,NaOH,PEA和混合物的种类。该方法可作为一种简便、快速、可靠的方法用于NaCl,NaOH,PEA和混合物的种类判别,并为PEA的合成和质量控制提供理论依据和技术支撑。

由50份烟草样品的近红外漫反射光谱组成的光谱矩阵经过主成分分析降维,采用基于支持向量机回归(SVR)算法,以常规化学分析方法测定的总糖、还原糖、总氮、烟碱的含量为参考值,建立了烟草中主要成分近红外光谱定量分析定标模型,并采用留一法交叉验证(LOOCV)对模型进行验证。以内部交叉验证预测的Rms.值为判据,从核函数类型、惩罚因子C和不敏感函数ε取值等方面对定标模型进行优化,获得不同成分定标模型的优化参数。烟草总糖、还原糖、总氮、烟碱优化定标模型的Rms.值分别为1.581,1.412,0.117和0.313。同时建立了烟草以上成分的偏最小二乘回归(PLS)、多元线性回归(MLR)以及误差反向传播人工神经网络(BP-ann)定标模型,通过内部交叉验证的Rms.值与SVR定标模型进行比较,结果表明SVR模型具有更好的预测效果。

目的:探讨cyclin D1在局部晚期口腔鳞癌患者中预后价值以及能否作为多西他赛联合顺铂、5-氟尿嘧啶(TPF)诱导化疗的预测生物标志物。方法:2008年3月至2010年12月上海交通大学医学院附属第九人民医院局部晚期口腔鳞状细胞癌患者256例行TPF诱导化疗的前瞻性随机临床试验为研究对象。随机分为试验组(术前TPF诱导化疗+手术+术后放疗)和对照组(手术+术后放疗)。采用免疫组织化学法检测患者活检标本中cyclin D1蛋白的表达情况,分析cyclin D1表达与行TPF诱导化疗患者预后的关系。结果:256例患者中232例符合cyclin D1检测条件,其中cyclin D1低表达者比高表达者有较高的总生存率(P=0.001)、无病生存率(P=0.003)、无局部复发生存率(P=0.004)和无远处转移生存率(P=0.001)。试验组和对照组之间的患者预后无差异,cyclin D1表达水平与患者行TPF诱导化疗后的疗效无显著相关性,但c N2患者中cyclin D1高表达者可从TPF诱导化疗在总生存率(P=0.024)和无远处转移生存率(P=0.024)中获益。结论:cyclin D1可作为局部晚期口腔鳞癌患者的预后生物标志物,cyclin D1高表达的c N2口腔鳞癌患者可从TPF诱导化疗中获益。
