Preserving Personalized Location Privacy in Ride-Hailing Service

Ride-hailing service has become a popular means of transportation due to its convenience and low cost.However, it also raises privacy concerns.Since riders' mobility information including the pick-up and drop-off location is tracked, the service provider can infer sensitive information about the riders such as where they live and work.To address these concerns, we propose location privacy preserving techniques that efficiently match riders and drivers while preserving riders' location privacy.We first propose a baseline solution that allows a rider to select the driver who is the closest to his pick-up location.However, with some side information, the service provider can launch location inference attacks.To overcome these attacks, we propose an enhanced scheme that allows a rider to specify his privacy preference.Novel techniques are designed to preserve rider's personalized privacy with limited loss of matching accuracy.Through trace-driven simulations, we compare our enhanced privacy preserving solution to existing work.Evaluation results show that our solution provides much better ride matching results that are close to the optimal solution, while preserving personalized location privacy for riders.
Effect of the high-power electromagnetic pulses on the reactivity of the coal-water slurry in hot environment

An effect of the high-power electromagnetic pulses onto the droplet of coal-water slurry inside the furnace was investigated.In contrary to the previously investigated laser-induced fuel atomization that occurs at the room temperature,the pre-heated (to 400 K) slurry becomes dry enough to prevent the explosion-like steam formation.Thus,fuel does not atomize and the ignition does not accelerate.Furthermore,the absorption of several laser pulses leads to evident sintering of irradiated surface with following increase of the ignition delay time for up to 24%.Variation of the pulse energy in range 48–118 mJ (corresponding intensity up to 2.4 J·cm~(-2)) leads to certain variation of the increase of ignition delay.The strong pulsed overheating of the coal water slurry which does not initiate the fine atomization of the fuel generally makes its ignition longer.
Bioaugmentation of two-stage aerobic sequencing batch reactor with mixed strains for high nitrate nitrogen wastewater treatment

Mixed strains Delftia sp.YH01 and Acidovorax sp.YH02,with capability of heterotrophic nitrification-aerobic denitrification,were introduced into a two-stage aerobic sequencing batch reactor to enhance NO_3~–-N removal.With optimal C/N of 8,efficient NO_3~–-N removal was achieved at initial NO_3~–-N concentration of 2000 mg·L~(-1).Meanwhile,the massive accumulation of NO_2~–-N was avoided during the long operation.Compared to the one-stage aerobic sequencing batch reactor,the removal efficiency of NO_3~–-N and TN in the two-stage aerobic sequencing batch reactor was increased by 36.5% and 42.7%,which respectively was 93.8% and 88.4%.Microbial community study showed that the mixed strains have the stronger viability and can synergistically denitrify with the indigenous microorganisms in system,such as Azoarcus,Uncultured Saprospiraceae,Thauera,Paracocccus,which could be major contributors for aerobic denitrification.The proposed technology was shown to achieve high-efficiency treatment of high NO_3~–-N wastewater through aerobic denitrification.

循环肿瘤DNA检测在卵巢癌诊治中的研究进展

卵巢癌早期病变缺乏特异性症状及可靠的早期诊断检测方法,约70%的卵巢癌患者初次诊断时已经为肿瘤晚期,晚期病变缺乏有效的监测和治疗方法,因而卵巢癌死亡率居高不下。肿瘤患者血液中的循环肿瘤DNA(ctDNA)携带有与原肿瘤细胞一致的基因组突变特征,通过ctDNA检测可以无创、连续和实时地监测肿瘤发生发展过程中的基因突变情况,患者易于接受,临床医生可以早期发现患者ctDNA基因突变情况,获得肿瘤是否发生和发生阶段情况,监测病情变化规律。本文通过就ctDNA的生物学特性、检测方法及其在卵巢癌诊治中的研究进展进行总结,以期建立完善ctDNA在卵巢癌早期诊疗中基因水平的动态监测方法,提高卵巢癌的检测和治疗效果。

Predicting Code Smells and Analysis of Predictions: Using Machine Learning Techniques and Software Metrics

Code smell detection is essential to improve software quality, enhancing software maintainability, and decrease the risk of faults and failures in the software system. In this paper, we proposed a code smell prediction approach based on machine learning techniques and software metrics. The local interpretable model-agnostic explanations (LIME) algorithm was further used to explain the machine learning model’s predictions and interpretability. The datasets obtained from Fontana et al. were reformed and used to build binary-label and multi-label datasets. The results of 10-fold cross-validation show that the performance of tree-based algorithms (mainly Random Forest) is higher compared with kernel-based and network-based algorithms. The genetic algorithm based feature selection methods enhance the accuracy of these machine learning algorithms by selecting the most relevant features in each dataset. Moreover, the parameter optimization techniques based on the grid search algorithm significantly enhance the accuracy of all these algorithms. Finally, machine learning techniques have high potential in predicting the code smells, which contribute to detect these smells and enhance the software’s quality.
Neural Explainable Recommender Model Based on Attributes and Reviews

Explainable recommendation, which can provide reasonable explanations for recommendations, is increasingly important in many fields. Although traditional embedding-based models can learn many implicit features, resulting in good performance, they cannot provide the reason for their recommendations. Existing explainable recommender methods can be mainly divided into two types. The first type models highlight reviews written by users to provide an explanation. For the second type, attribute information is taken into consideration. These approaches only consider one aspect and do not make the best use of the existing information. In this paper, we propose a novel neural explainable recommender model based on attributes and reviews (NERAR) for recommendation that combines the processing of attribute features and review features. We employ a tree-based model to extract and learn attribute features from auxiliary information, and then we use a time-aware gated recurrent unit (T-GRU) to model user review features and process item review features based on a convolutional neural network (CNN). Extensive experiments on Amazon datasets demonstrate that our model outperforms the state-of-the-art recommendation models in accuracy of recommendations. The presented examples also show that our model can offer more reasonable explanations. Crowd-sourcing based evaluations are conducted to verify our model’s superiority in explainability.

Passive scalar mixing induced by the formation of compressible vortex rings

This study aims to determine the relationship between the physical features of a compressible vortex and the mixing process. Such relationship is of significant importance to design combustors that can achieve optimal or most effective mixing. The passive scalar mixing induced by the formation of a canonical compressible vortex ring (CVR) generated at the end of a shock tube is investigated by using numerical simulation. In addition, the method of finite-time Lyapunov exponent (FTLE) field are detected to identify the region of CVR, as well as to analyze the passive scalar mixing during the CVR formation. As the CVR rolls up, the ambient fluid outside the shock tube is entrained into the ring. The entrainment fraction (the mass of entrained fluid to the total mass of CVR) is found to strongly depend on two features of CVRs. One is the compressibility of CVRs, which is characterized by the Mach number of the incident shock denoted by Mach number (Ma). The other is pinch-off of CVRs, which happens at a certain timescale with narrow range of 2–4. As Ma increases, the entrainment fraction of the leading CVR decreases linearly due to smaller vortex core and weaker radial diffusion of vorticity generated by larger compressibility. After CVRs pinch off, trailing vortices appear and show less effective at entrainment than the leading CVRs do. Moreover, the tendency of the rate of entrainment is examined. The results indicate that increasing compressibility and total fluid flux are in favor of the rate of entrainment but restrain the entrainment fraction of total jet.
In situmethod for stress measurements in film-substrate electrodes during electrochemical processes: key role of softening and stiffening

Electrode stress is one of the main driving forces of electrochemical degradation, which is directly related to battery cycle life, thus attracting great interest. Herein, we propose an in situ method to measure bilayer stresses in film-substrate electrodes during electrochemical processes. This method consists of two parts: stress models featuring Li-dependent material modulus and in situ deformation measurements, through which electrode bilayer stresses evolution accompanied by Li-dependent material modulus can be quantitatively characterized. As application of the method, typical silicon-composite and carboncomposite film-substrate electrodes are selected for in situ mechanical measurements and experimental analysis is performed. Results show that silicon material and carbon material exhibit significant, continuous softening and stiffening, respectively. In two film-substrate electrodes, electrode material films experience compressive stress and current collector substrates undergo a tensile-to-compressive conversion across the thickness. Besides, moduli and stresses in both electrodes vary nonlinearly with capacity, presenting non-overlapping paths between lithiation and delithiation. Based on experimental data, we further demonstrate the key role of Li-dependent modulus on electrode stresses, finding that silicon material softening decreases and carbon material stiffening increases electrode stresses. The deficiencies of current stress measurement method based on Stoney equation and the applicability of our method are discussed.
CoN_x C active sites-rich three-dimensional porous carbon nanofibers network derived from bacterial cellulose and bimetal-ZIFs as efficient multifunctional electrocatalyst for rechargeable Zn–air batteries

In this work, a CoN_x C active sites-rich three-dimensional porous carbon nanofibers network derived from bacterial cellulose and bimetal-ZIFs is prepared via a nucleation growth strategy and a pyrolysis process. The material displays excellent electrocatalytic activity for the oxygen reduction reaction, reaching a high limiting diffusion current density of -7.8 mA cm~(-2), outperforming metal–organic frameworks derived multifunctional electrocatalysts, and oxygen evolution reaction and hydrogen evolution reaction with low overpotentials of 380 and 107 mV, respectively. When the electrochemical properties are further evaluated, the electrocatalyst as an air cathode for Zn-air batteries exhibits a high cycling stability for 63 h as well as a maximum power density of 308 mW cm~(-2), which is better than those for most Zn-air batteries reported to date. In addition, a power density of 152 mW cm~(-2) is provided by the solid-state Zn-air batteries, and the cycling stability is outstanding for 24 h. The remarkable electrocatalytic properties are attributed to the synergistic effect of the 3D porous carbon nanofibers network and abundant inserted CoN_x C active sites, which enable the fast transmission of ions and mass and simultaneously provide a large contact area for the electrode/electrolyte.
Real-time geochemistry of urban aerosol during a heavy dust episode by single-particle aerosol mass spectrometer: Spatio-temporal variability, mixing state and spectral distribution

A heavy dust episode occurred from May 3 to 8, 2017 in China, with an influenced area exceeding 1.63 million km 2. In this work, the mixing state of aerosols and their spectral distributions were simultaneously observed in the sand source region of Hohhot and the long-range dust transport region of Nanjing by using a single-particle aerosol mass spectrometer (SPAMS). The duration time of this dust episode was 37–40 h in Hohhot and prolonged to 51–104 h in Nanjing. Totals of 336,135 (Hohhot) and 235,840 (Nanjing) particles in PM_(2.5) were successfully ionized to identify 10 main particle classes. During this episode, aerosol particles including OCEC (30.65%), K (22.42%), K-CN (17.03%), sodium (9.46%), heavy metal (8.96%), EC-sulfate (3.46%) and Al (3.22%) were prevailing in Hohhot and were dominated by EC-sulfate (22.26%), OCEC (15.21%), heavy metal (11.96%), K (13.68%), sodium (12.27%), Al (10.54%) and EC (9.02%) in Nanjing. The spectral distribution peaked at 0.66 µm during the dust episode in Nanjing, 0.12 µm larger than the peak size in the non-dust episode. Strong signals at –62[NO_3 ] ~– and –61[HCO_3 ] ~–/–61[C 5 H] ~– for aerosol particles were observed in Hohhot and Nanjing respectively. The proportions of K-CN, sodium, heavy mental, OCEC and EC-sulfate particles in the dust episode of Hohhot were 2.75, 1.41, 1.80, 1.22 and 1.28 times as large as the values in the non-dust episode. For Nanjing, the fractions of EC-sulfate, EC, Al particles in the dust episode were 10.55, 4.65 and 1.46 times higher than values in the non-dust episode. The proportions of EC-secondary and EC-nitrate particles were found to decrease in the dust episode in the two regions.
Characterization of the flowability dynamics of granular material flowing down a narrow channel

The flowability of granular material is commonly determined from shear cell tests, but in the real world, the granular flow is quite different in many cases. For this paper, the flowabilities in a narrow channel of five different granular materials were investigated. The flow parameters of the granular flows were determined to classify the flowabilities. Granular flow surface velocities and flow heights and thicknesses were measured, and it was found that the mean shear rates in the linear portions of the velocity profiles increase with both flow rates and inclination. A universal parameter, the ratio of the sine of the inclination to the shear rate in the linear part of the velocity profile, is proposed as a constant. This constant is independent of particle properties. In addition, a flowability parameter, the ratio of the mean shear rate to the cosine of the inclination, is proposed to characterize the friction between the particles in the flowing granular material.
Enhanced stability of Pt/Al_2O_3 modified by Zn promoter for catalytic dehydrogenation of ethane

Catalytic ethane dehydrogenation (EDH) to ethylene over Pt-based catalysts has received increasing interests in recent years as it is a potential alternative route to conventional steam cracking. However, the catalysts used in this reaction often suffer from rapid deactivation due to serious coke deposition and metal sintering. Herein, we reported the effects of Zn modification on the stability of Pt/Al_2O_3 for EDH. The Zn-modified sample (PtZn_2/Al_2O_3) exhibits stable ethane conversion (20%) with over 95% ethylene selectivity. More importantly, it exhibits a significantly low deactivation rate of only 0.0 03 h~(–1) at 60 0 °C for 70 h, which surpasses most of previously reported catalysts. Detailed characterizations including in situ FT-IR, ethylene adsorption microcalorimetry, and HAADF-STEM etc. reveal that Zn modifier reduces the number of Lewis acid sites on the catalyst surface. Moreover, it could modify Pt sites and preferentially cover the step sites, which decrease surface energy and retard the sintering of Pt particle, then prohibiting the further dehydrogenation of ethylene to ethylidyne. Consequently, the good stability is realized due to anti-sintering and the decrease of coke formation on the PtZn_2/Al_2O_3 catalyst.
A 530 nA quiescent current low-dropout regulator with embedded reference for wake-up receivers

Low power transceivers are essential in the wireless personal area network (WPAN) applications. To reduce transceivers' power in standby mode, wake-up receivers (WuRx's) are now widely used in WPAN applications. Those WuRx's are always-on in the system and are usually powered by batteries. A compact low-dropout (LDO) voltage regulator with very small quiescent current is required to convert the battery voltage to the desired working voltage.
Model Test of Deformation Evolution and Multi Factor Prediction of Anchorage Slope Stability under Rainfall Condition

The stability of the anchorage slope on the Baiyang Yangtze River Highway Bridge in Yichang, China, was investigated under different rainfall conditions using model test, numerical simulation, and factor analysis. The results of the study are as follows: (1) with the increase of rainfall intensity, the change of earth pressure can be divided into three stages. However, when the rainfall intensity was larger than a certain value, the change of earth pressure of cut slope became two stages; with the increase of rainfall intensity, pore water pressure increased with the increase of rainfall time, while at a certain stage after the rainfall, the pore water pressure in the cut slope did not decrease immediately, but increased for a period of time. (2) When the rainfall stopped, the stability coefficient of the anchorage slope continued to decrease, then slowly increased, and finally tended to be gentle. Meanwhile, when the rainstorm reached a certain intensity, the main factor that restricted the rainfall infiltration rate became the geotechnical permeability coefficient of the cut slope, which was no longer the rainfall intensity. (3) Factor analysis shows that the rainfall intensity and rainfall duration were the most important factors for anchorage slope stability, while earth pressure, pore water pressure and slope displacement were much less significant.
Crystal Structure, Thermal Expansivity and High-Temperature Vibrational Spectra on Natural Hydrous Rutile

A natural rutle sample was measured by in situ high-temperature X-ray diffraction (XRD) patterns, as well as Raman and Fourier transform infrared (FTIR).Crystal structure is refined on the sample with 1.4 mol.% Fe and 510±120 ppmw.H_2O.The unit-cell and TiO_6 octahedral volumes are expanded by 0.7%–0.8% for Fe~(3+) incorporation, as compared with the reported Ti-pure samples.The volumetric thermal expansion coefficient (α, K~(-1)) could be approximated as a linear function of T (K): 4.95(3)×10~(-9)×T+21.54(5)×10~(-6), with the averaged value α_0=30.48(5)×10~(-6) K~(-1), in the temperature range of 300–1 500 K.The internal Ti-O stretching (A_(1g) and B_(2g)) and O-Ti-O bending (E_g) modes show ‘red shift’, whereas the multi-phonon process exhibits ‘blue shift’ at elevated temperature.The rotational mode (B_(1g)) for TiO_6 octahedra is nearly insensitive to temperature variations.The OH-stretching bands at 3 279 and 3 297 cm~(-1) are measured by high-temperature spectroscopy experiments.Both the IR-active and Raman-active OH-stretching modes shift to lower frequencies at higher temperature, with the signal intensities decreasing.And after quenching, we expect about 43% dehydration around 873 K, and 85% dehydration at 1 273 K for this hydrous sample.
Mixing Characteristics of Oil Inclusions with Different Thermal Maturities in the Wenliu Uplift, Dongpu Depression, Bohai Bay Basin, North China

Multiple types of oil inclusions with different fluorescence colors have been detected in the northern Dongpu depression. Recent evidences show that these inclusions may have been trapped simultaneously or during a very short period. Therefore, whether these oils were mixed before trapping is unknown. In this study, we analyzed the petrography and fluorescence spectral characteristics of oil inclusions in the Wenliu uplift in the northern Dongpu depression, and assessed the data with the oil mixing ratio curve obtained in the previous experiment. The results show that there are three types of oil inclusions (type I, type II and type III) with yellow, green and blue fluorescence colors, corresponding to low-mature, medium-mature and high-mature oil, respectively. The “pure” oil inclusions, do exist in type II and type III group of oil inclusions, showing the medium-mature oil was generated from the source rock rather than being formed by the mixture of high-mature and low-mature end oils. Most of the oil inclusions are mixtures of high-mature and medium-mature end oils from the sub-sags to the Wenliu uplift, the mixing degree increases to close to 50%. The oil between the Qianliyuan sub-sag and the Wenliu uplift was mainly mixed by medium mature oils, whereas the oil between the Liutun sub-sag and the Wenliu uplift was mainly mixed by high mature oil.

人工颈椎间盘置换术的手术流程及技术要点

颈椎前路减压椎间植骨融合术(anterior cervical discectomy and fusion, ACDF)是目前治疗颈椎病应用最为广泛的手术之一,具有直接神经减压、创伤小、出血少、恢复快等诸多优势。但ACDF使得手术节段丧失活动度,导致手术邻近节段应力增加,术后易增加邻近节段并发症的发生率。人工颈椎间盘置换术(artificial cervical disc replacement,ACDR)能够保留手术节段的活动度,理论上能够避免或大幅度减小对邻近节段的不良影响,减少术后邻近节段退变(adjacent segment degeneration, ASD)的发生。相关研究表明,ACDR的临床疗效与ACDF相当,术后ASD的发生率相对较低。目前应用于临床的人工颈椎间盘类型较多,包括Prestige假体、Bryan假体、Mobi-C假体、ProDisc-C假体等,不同类型假体使用方式、手术操作略有差异。笔者以Prestige假体的ACDR为例,对手术操作过程、技术要点进行总结,对ACDR的适应证、围手术期管理等方面进行简要介绍。

据世界卫生组织统计数据显示,心血管疾病已成为威胁人体健康的“第一杀手”.全球5690万例死亡人群中,约有1790万人死于心血管疾病,占全球死亡总数的31%,其中,超过80%死于心脏病和中风.我国也是心血管疾病大国,心血管病患人数已达到2.9亿.面对老年心血管疾病的威胁,人们从最初的“治已病”转向聚焦“治未病”,在临床上逐渐开始采用可穿戴式柔性电子技术作为新兴的一种健康监测手段,从而实现对心血管相关生理参数的实时、连续监测.在柔性传感的研究中,压阻传感器可以将外界压力引起的材料电阻变化转化为电信号输出,此类压阻传感器和技术可实现对心血管系统健康状态的脉搏和血压等参数监测,并且具有结构简单、制备成本低、易操作等优点.但传统的压敏材料的内部结构及其制备方法导致了传感器的不稳定性和低的灵敏度,因而需要研究人员持续研究更高效的新材料来解决上述问题.作为一种新型的二维过渡金属碳化物或碳氮化物(MXene),层状MXene在外界压力作用下,内部层间距将发生极大变化,从而使得基于MXene的压力传感器能够获得较高的灵敏度.北京航空航天大学单光存研究组与西北工业大学黄维研究组合作,研制了一种新型的基于高导电性MXene和具有多孔结构聚乙烯醇缩丁醛(PVB)材料的高灵敏压阻传感器,实现了兼具检测范围宽、检测限低、检测电压低、功耗低、响应时间快、机械稳定性好等优点的高性能高灵敏柔性传感器.相关研究成果发表于Nanoscale上.
