Researchers have recently achieved significant advances in deep learning techniques, which in turn has substantially advanced other research disciplines, such as natural language processing, image processing, speech recognition, and software engineering. Various deep learning techniques have been successfully employed to facilitate software engineering tasks, including code generation, software refactoring, and fault localization. Many studies have also been presented in top conferences and journals, demonstrating the applications of deep learning techniques in resolving various software engineering tasks. However,although several surveys have provided overall pictures of the application of deep learning techniques in software engineering,they focus more on learning techniques, that is, what kind of deep learning techniques are employed and how deep models are trained or fine-tuned for software engineering tasks. We still lack surveys explaining the advances of subareas in software engineering driven by deep learning techniques, as well as challenges and opportunities in each subarea. To this end, in this study, we present the first task-oriented survey on deep learning-based software engineering. It covers twelve major software engineering subareas significantly impacted by deep learning techniques. Such subareas spread out through the whole lifecycle of software development and maintenance, including requirements engineering, software development, testing, maintenance, and developer collaboration. As we believe that deep learning may provide an opportunity to revolutionize the whole discipline of software engineering, providing one survey covering as many subareas as possible in software engineering can help future research push forward the frontier of deep learning-based software engineering more systematically. For each of the selected subareas,we highlight the major advances achieved by applying deep learning techniques with pointers to the available datasets i

A crosstalk-free multichannel sensor based on a dual-Sagnac interferometer interrogated by microwave photonic filter (MPF) is demonstrated theoretically and experimentally in this paper. The dual-Sagnac interferometer is taken as the sensing element as well as an optical spectrum slicer to implement a dual-passband MPF. Experimental results show that the proposed multichannel sensor is crosstalk-free， and the temperature sensitivity of each channel is -0.9884 MHz/℃ and -1.9302 MHz/℃， respectively. The sensing interrogation system has good linearity and stability and it is suitable for application scenarios where multiple points of temperature are required to monitor simultaneously.

Optoelectronics Letters 2025年

作者： LIN Rui ZHANG Ailing CHANG Pengxiang PAN Honggang wang Minghe wang bo Engineering Research Center of Optoelectronic Devices & Communication Technology， Ministry of Education， Tianjin Key Laboratory of Film Electronic and Communication Devices， School of Electrical and Electronic Engineering， Tianjin University of Technology

A high sensitivity fiber optic temperature sensor based on Vernier effect in microwave photonic filter based on two paralleled F-P (Fabry-Perot) fiber ring is proposed and experimentally verified. Sensitivity is improved through the Vernier effect， which is caused by two parallel F-P fiber rings with approximate lengths. Temperature interrogation is achieved by monitoring the notch frequency of the superimposed frequency response curve. The temperature sensitivity of -484.514kHz/℃ is achieved in experiment， which is 57 times of the sensor without Vernier effect. The improved sensitivity and simple structure make it have wide potential applications in temperature monitoring of power systems.

目的根据CT影像及肿瘤标志物结果,建立低分化腺癌预测模型,并进行内部验证。方法选择2023年在南京医科大学附属脑科医院胸外科行手术治疗的实性与部分实性肺结节患者,按照7∶3比例将患者随机分为训练集和验证集。收集患者CT特征,包括结节平均密度值、最大直径、胸膜牵拉征和支气管充气征,以及肿瘤标志物结果。依据术后病理结果,将患者分为低分化腺癌组和非低分化腺癌组。对训练集采用单因素分析和logistic回归分析,并以此建立预测模型,采用受试者工作特征(receiver operating characteristic,ROC)曲线评估模型区分度,校准曲线评估模型的一致性,绘制决策曲线评估该模型的临床价值,并在验证集中校验模型。结果共纳入299例患者,其中男103例、女196例,中位年龄57.00(51.00,67.25)岁;训练集211例,验证集88例。多因素分析显示癌胚抗原(CEA)值[OR=1.476,95%CI(1.184,1.983),P=0.002]、细胞角蛋白19片段抗原(CYFRA21-1)值[OR=1.388,95%CI(1.084,1.993),P=0.035]、肿瘤最大直径[OR=6.233,95%CI(1.069,15.415),P=0.017]、肿瘤平均密度[OR=1.083,95%CI(1.020,1.194),P=0.040]是实性与部分实性肺结节低分化腺癌的独立危险因素。基于此构建预测模型,ROC曲线下面积为0.896[95%CI(0.810,0.982)],最大约登指数对应截点值为0.103,灵敏度为0.750,特异度为0.936。bootstrap法抽样1000次,校准曲线图预测概率与实际风险一致。决策曲线分析表明,在全预测概率下均有正收益,有较好临床价值。结论对于实性与部分实性肺结节患者,术前使用CT测量肿瘤平均密度值、最大直径,同时联合肿瘤标志物CEA、CYFRA21-1值可有效预测结节是否为低分化腺癌,以尽早予以干预。

作为全球重要的碳库,湿地在缓解气候变化方面发挥了重要作用。然而在全球变暖背景下,湿地的碳排放(尤其是甲烷(CH_(4))排放)存在高度变异性和不确定性,极大地削弱了湿地碳库功能的发挥。为了探究不同水深梯度下东北盐碱湿地碳排放通量的特征,本研究以莫莫格湿地为主要研究区,选取5种代表性植被(芦苇(Phragmites australis)、扁秆藨草(bolboschoenus planiculmis)、三江藨草(Schoenoplectus nipponicus)、香蒲(Typha orientalis ***)和碱蓬(Suaeda glauca)),布设Marsh Organ中型实验生态系统模拟不同水深生境,揭示CH_(4)和二氧化碳(CO_(2))排放通量变化及其环境影响因子。结果表明,莫莫格湿地-10~50 cm水深范围内5种代表性植被生长季CH_(4)排放通量范围为0.07~86.74 mg/(m^(2)·h),平均值为8.89 mg/(m^(2)·h),其主要环境影响因素为水深、气温和表层10 cm土壤含水量;在研究水深范围内,代表性植被生长季CO_(2)排放通量范围为10.59~1891.08 mg/(m^(2)·h),平均值为450.12 mg/(m^(2)·h),其主要环境影响因素为水深、气温和表层10 cm土壤含水量。不同植被对碳排放的贡献量有所差异,具体来说,芦苇和香蒲的CH_(4)排放通量最高,而藨草的CO_(2)排放通量最高。碳排放随水深变化呈现分段规律,CH_(4)排放随水深变化呈现先增加后减少的趋势,而CO_(2)则呈现相反规律,随水深变化先减小后增加,其水深临界阈值均出现在22 cm处。在不同水深范围内,CO_(2)排放对于水深的敏感性均大于CH_(4),且当水深大于22 cm时,CH_(4)和CO_(2)均呈现出更高的水深敏感性。碳排放在不同水深范围对温度的敏感程度不同,当水深小于22 cm时,CH_(4)和CO_(2)均呈现出更高的温度敏感性,然而当水深大于22 cm时,二者对温度均不敏感。结果表明升温背景下,东北典型盐碱湿地水陆过渡区关键生态系统在不同水深范围内呈现出不对称的响应模式,频繁的水位波动会极大地改变湿地碳排放格局,从而影响到湿地碳功能的稳定发挥。

The dynamic stability of axially moving viscoelastic Rayleigh beams is pre- sented. The governing equation and simple support boundary condition are derived with the extended Hamilton＇s principle. The viscoelastic material of the beams is described as the Kelvin constitutive relationship involving the total time derivative. The axial tension is considered to vary longitudinally. The natural frequencies and solvability condition are obtained in the multi-scale process. It is of interest to investigate the summation parametric resonance and principal parametric resonance by using the Routh-Hurwitz criterion to obtain the stability condition. Numerical examples show the effects of viscos- ity coefficients, mean speed, beam stiffness, and rotary inertia factor on the summation parametric resonance and principle parametric resonance. The differential quadrature method （DQM） is used to validate the value of the stability boundary in the principle parametric resonance for the first two modes.

为探究苯丙噻二唑(benzothiadiazole,BTH)处理对葡萄生长过程中果实氨基酸积累及其降解代谢的影响,以‘霞多丽’葡萄为实验植株,果实转色期喷施50 mg/L BTH,花后60 d开始每10 d采集1次样品直至果实成熟(花后110 d),使用高效液相色谱法、氨基酸自动分析仪、固相微萃取联合气相色谱-质谱联用仪分别分析果实的葡萄糖、果糖、蔗糖、有机酸和氨基酸含量,以及氨基酸降解代谢相关酶活性和相应香气产物。结果表明:谷氨酸、精氨酸和脯氨酸是‘霞多丽’葡萄果实的主要氨基酸,BTH处理可促进果实氨基酸积累,抑制果实葡萄糖、果糖和蔗糖生成,提高成熟果实的酒石酸和柠檬酸含量,降低苹果酸含量;同时,BTH处理抑制了果实游离态支链脂肪族香气化合物的生成,增强了成熟葡萄的氨基酸转移酶(aminotransferase,AT)、醇酰基转移酶(alcohol acyltransferase,AAT)和丙酮酸脱羧酶活力,改变了氨基酸总量与乙醇脱氢酶活力的相关性及AT和AAT活力与单糖和有机酸含量的相关性,进而影响了氨基酸代谢香气物质的生成。研究结果可为BTH调控葡萄品质的应用提供理论指导及实践依据。
