Pedestrian evacuation at the subway station under fire

With the development of urban rail transit, ensuring the safe evacuation of pedestrians at subway stations has become an important issue in the case of an emergency such as a fire. This paper chooses the platform of line 4 at the Beijing Xuanwumen subway station to study the emergency evacuation process under fire. Based on the established platform, effects of the fire dynamics, different initial pedestrian densities, and positions of fire on evacuation are investigated. According to simulation results, it is found that the fire increases the air temperature and the smoke density, and decreases pedestrians’ visibility and walking velocity. Also, there is a critical initial density at the platform if achieving a safe evacuation within the required 6 minutes. Furthermore, different positions of fire set in this paper have little difference on crowd evacuation if the fire is not large enough. The suggestions provided in this paper are helpful for the subway operators to prevent major casualties.
Computational analysis of the roles of biochemical reactions in anomalous diffusion dynamics

Most biochemical processes in cells are usually modeled by reaction–diffusion (RD) equations. In these RD models, the diffusive process is assumed to be Gaussian. However, a growing number of studies have noted that intracellular diffusion is anomalous at some or all times, which may result from a crowded environment and chemical kinetics. This work aims to computationally study the effects of chemical reactions on the diffusive dynamics of RD systems by using both stochastic and deterministic algorithms. Numerical method to estimate the mean-square displacement (MSD) from a deterministic algorithm is also investigated. Our computational results show that anomalous diffusion can be solely due to chemical reactions. The chemical reactions alone can cause anomalous sub-diffusion in the RD system at some or all times. The time-dependent anomalous diffusion exponent is found to depend on many parameters, including chemical reaction rates, reaction orders, and chemical concentrations.
Effects of Mg substitution on the structural and magnetic properties of Co_(0.5)Ni_(0.5-x)Mg_xFe_2O_4 nanoparticle ferrites

In this study, nanocrystalline Co–Ni–Mg ferrite powders with composition Co_(0.5)Ni_(0.5-x)Mg_xFe_2O_4 are successfully synthesized by the co-precipitation method. A systematic investigation on the structural, morphological and magnetic properties of un-doped and Mg-doped Co–Ni ferrite nanoparticles is carried out. The prepared samples are characterized using x-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), and vibrating sample magnetometry (VSM). The XRD analyses of the synthesized samples confirm the formation of single-phase cubic spinel structures with crystallite sizes in a range of ~32 nm to ~36 nm. The lattice constant increases with increasing Mg content. FESEM images show that the synthesized samples are homogeneous with a uniformly distributed grain. The results of IR spectroscopy analysis indicate the formation of functional groups of spinel ferrite in the co-precipitation process. By increasing Mg~(2+) substitution, room temperature magnetic measurement shows that maximum magnetization and coercivity increase from ~57.35 emu/g to ~61.49 emu/g and ~603.26 Oe to ~ 684.11 Oe (1 Oe = 79.5775 A·m~(-1)), respectively. The higher values of magnetization M_s and M_r suggest that the optimum composition is Co_(0.5)Ni_(0.4)Mg_(0.1)Fe_2O_4 that can be applied to high-density recording media and microwave devices.
Compressed sensing sparse reconstruction for coherent field imaging

Return signal processing and reconstruction plays a pivotal role in coherent field imaging, having a significant influence on the quality of the reconstructed image. To reduce the required samples and accelerate the sampling process, we propose a genuine sparse reconstruction scheme based on compressed sensing theory. By analyzing the sparsity of the received signal in the Fourier spectrum domain, we accomplish an effective random projection and then reconstruct the return signal from as little as 10% of traditional samples, finally acquiring the target image precisely. The results of the numerical simulations and practical experiments verify the correctness of the proposed method, providing an efficient processing approach for imaging fast-moving targets in the future.
低承台桩基础对地表土体振动的影响分析

建立了基于Biot波动方程的三维显式有限元计算方法,分析饱和地基中低承台桩基在简谐荷载作用下,桩基对桩周地表土振动的影响。采用1/3倍频程分析技术评价地表的振动量级,参数计算分四组,分别探讨土骨架的剪切模量、激振频率、承台板埋深比、平面尺寸的影响规律。结果表明:从减小水平向振动来考虑,承台埋深比宜取0.4~0.5,承台板厚宜取较大值;从减小竖直向振动来考虑,承台埋深及承台板厚的取值与土骨架剪切模量有关,建议承台量纲为一的板宽取0.5;桩基在较低频率荷载作用下对地表振动的放大作用要比较高频率荷载作用强。
网络协同攻击:乌克兰停电事件的推演与启示

电力基础设施与信息基础设施之间存在相互依存关系,但二者却是两种完全不同的网络。从基础设施构成角度分析,电力基础设施由可以承受高电压、大电流的电力一次元件组成,而信息基础设施由负责通信和信息处理的电力二次元件组成,在构成上存在明显差异;从传输内容分析,电力基础设施中传输的是电流,而信息基础设施中传输的是信息流,传输内容明显不同。尽管针对每种基础设施的分析都可借鉴成熟的研究方法,但对于其依存关系的建模却刚刚起步,并因两基础设施的差异而存在较大困难。从复杂网络的视角,现代电力系统可视为信息网和物理网相互依存的超大规模二元复合网络,研究其安全理论特别是信息安全对整个电力系统运行的影响,在理论和工程两方面均具有重要意义。在这种情况下,就需要分析网络安全事件引起信息网故障,进而作用到物理网的动态过程与内在机理。到目前为止,针对该领域的研究仍缺乏完善的分析方法及工具。

The evolution and enlightenment of water resources accounting from accounts to balance sheet

The Third Plenary Session of the 18th Central Committee of the Communist Party of China has proposed an important national strategic decision: to explore and establish the balance sheet of natural resources, to implement leaders' of-office auditing system about natural resources assets. Water is one of the most essential nature resources of human beings; water resources accounting, as an important water resources management tool, is an essential part of compiling the natural resources balance sheet. In this paper, we provide a summary of the historic evolution of water resources accounting and analyze its application in some typical countries. Although water resources accounting and water resources balance sheet reflect different implications and focus, both require water resources accounts as the basis in system establishment.
Characteristics and source of aerosols at Shiyi Glacier, Qilian Mountains, China

Aerosol samples were collected in the Shiyi Glacier, Qilian Mountains from July 24 to August 19, 2012 and analyzed for major water-soluble ionic species (F~–, Cl~–, NO_2~–, NO_3~–, SO_4~(2–), Na~+, NH_4~+, K~+, Mg~(2+) and Ca~(2+)) by ion chromatography. SO_4~(2–) and NH_4~+ were the most abundant components of all the anions and cations, with average concentrations of 94.72 and 54.26 neq/m~3, respectively, accounting for 34% and 20% of the total water-soluble ions analyzed. These mean ion concentrations were generally comparable with the background conditions in remote sites of the Qilian Mountains, but were much lower than those in certain cities in China. The particles were grouped into two dominant types according to their morphology and EDX signal: Si-rich particles and Fe-rich particles. Backward air mass trajectory analysis suggested that inland cities may contribute some anthropogenic pollution to this glacier, while the arid and semi-arid regions of central Asia were the primary sources of the mineral particles.
Characteristics of land-atmosphere energy and turbulent fluxes over the plateau steppe in central Tibetan Plateau

The land-atmosphere energy and turbulence exchange is key to understanding land surface processes on the Tibetan Plateau (TP). Using observed data for Aug. 4 to Dec. 3, 2012 from the Bujiao observation point (BJ) of the Nagqu Plateau Climate and Environment Station (NPCE-BJ), different characteristics of the energy flux during the Asian summer monsoon (ASM) season and post-monsoon period were analyzed. This study outlines the impact of the ASM on energy fluxes in the central TP. It also demonstrates that the surface energy closure rate during the ASM season is higher than that of the post-monsoon period. Footprint modeling shows the distribution of data quality assessments (QA) and quality controls (QC) surrounding the observation point. The measured turbulent flux data at the NPCE-BJ site were highly representative of the target land-use type. The target surface contributed more to the fluxes under unstable conditions than under stable conditions. The main wind directions (180° and 210°) with the highest data density showed flux contributions reaching 100%, even under stable conditions. The lowest flux contributions were found in sectors with low data density, e.g., 90.4% in the 360° sector under stable conditions during the ASM season. Lastly, a surface energy water balance (SEWAB) model was used to gap-fill any absent or corrected turbulence data. The potential simulation error was also explored in this study. The Nash-Sutcliffe model efficiency coefficients (NSEs) of the observed fluxes with the SEWAB model runs were 0.78 for sensible heat flux and 0.63 for latent heat flux during the ASM season, but unrealistic values of –0.9 for latent heat flux during the post-monsoon period.
Continued Study on Hohlraum Radiation Source with Approximately Constant Radiation Temperature

An experiment was performed on the Shenguang III prototype laser facility to continue the study on hohlraum radiation source with approximately constant radiation temperature using a continuously shaped laser pulse. A radiation source with a flattop temperature of about 130 eV that lasted about 5 ns was obtained. The previous analytical iteration method based on power balance and self-similar solution of ablation was modified taking into account the plasma movements and it was used to design the laser pulse shape for experiment. A comparison between experimental results and simulation is presented and better agreement was achieved using the modified method. Further improvements are discussed.
当前我国自然保护区管理中存在的问题与对策思考

今年是中国自然保护区事业发展六十周年。纵观其发展历程,中国自然保护区体系建设取得的成绩令世人瞩目,是中国生物多样性保护的主力军。 在当前生态文明建设的大背景下,自然保护事业受到空前的重视。无论是今年的“两会”(第十二届全国人民代表大会第四次会议和全国政协十二届四次会议),还是刚刚发布的《中华人民共和国国民经济和社会发展第十三个五年规划纲要》都体现了国家对生态环境和自然保护工作的重视。习近平主席也多次强调:要像保护眼睛一样保护生态环境,像对待生命一样对待生态环境,推动形成绿色发展方式和生活方式。这可视为经济发展新常态下自然保护的政治基础。
超声诊断真两性畸形1例

真两性畸形需与假两性畸形鉴别,真两性畸形的声像图特征为腹腔内可同时测及含有卵泡的卵巢回声和睾丸样均匀低回声区,而假两性畸形只能在体内测及其中一种组织回声。因此,临床上除体格检查、内分泌检查、尿生殖窦造影、染色体核型分析外,超声检查不仅能显示内生殖器官的有无,且可观察、评价其部位、大小、形态、结构等,为临床诊断和治疗提供重要的影像学依据。
上前牙畸形根面沟牙髓及牙周联合治疗一例

畸形根面沟是指牙齿组织钙化之前,由于成釉器过度卷叠或局部过度增殖深入牙乳头导致的先天性牙体发育异常类疾病。临床上表现为一条贯穿患牙牙冠至牙根的纵行裂沟。此类患牙常因治疗效果不佳而拔除。近年来随着牙周组织再生术的不断应用及内科技术的不断创新,多数患牙可得以保留。有报道可以通过根管治疗配合根尖区手术、牙周引导组织再生术治疗畸形根面沟,保留患牙。辽宁医学院附属第二医院显微根管治疗中心收治1例上前牙畸形根面沟患者,报道如下。
支气管扩张合并肺畸胎瘤1例

IPT可见于儿童和老年人,常发生于左侧,以上肺多见,这可能与IPT和胚胎发育早期胸腺的异位和分离有关。IPT特异性的临床表现为咳出毛发等异物,但发生率只有13?,大部分患者表现为胸痛、咳嗽、咯血等。和其他部位的畸胎瘤一样,IPT通常包含一些组织或器官的成分,如牙齿、毛发、皮肤、骨头,甚至内分泌腺体等。IPT大部分为良性,恶性的畸胎瘤常为实性或结节状,良性的畸胎瘤因含成熟的组织和脂肪,常表现为囊状,因此也称为囊性成熟畸胎瘤。对于IPT的诊断,应排除生殖腺体肿瘤的肺转移,此外还应与肺包虫病,曲菌球以及肺脓肿等鉴别。CT检查有助于IPT的诊断,因为CT可以评估病变内不同成分的密度。支气管镜检查如直接发现管腔内毛发样物体及肉样凸起,则应高度怀疑IPT。IPT一旦确诊,应早期手术切除。据统计,20%~ 30%的良性IPT组织内含有不成熟成分,可能演变为恶性侵袭性肿瘤。手术一般为肺叶切除,本例因合并左上、下肺支气管扩张,手术切除左全肺。
两种不同超滤技术在急诊体外循环心脏手术中影响输血量的比较

心脏手术失血和输血量较多,英美等西方国家10% ~ 20%的血液用于心脏手术。如何减少心脏手术围手术期输血成为当前临床工作研究热点之一。2010年5月至2015年6月,我们对52例急诊体外循环心脏手术患者采用两种不同超滤技术,回顾性分析输血情况如下。
Ⅱ型固有淋巴细胞在特应性皮炎中作用机制的研究进展

Ⅱ型固有淋巴细胞(type II innate lymphoid cell, ILC2)是一种新型的固有淋巴细胞群体,活化后可以分泌大量的Th2型细胞因子IL-5、IL-13,主要介导Ⅱ型免疫应答,在抵御寄生虫感染、呼吸道疾病和组织修复中发挥了重要作用。特应性皮炎(atopic dermatitis, AD)是一种慢性复发性皮肤疾病,急性期病理过程主要表现为Th2细胞所介导的Ⅱ型免疫反应。近来发现,ILC2大量存在于人类皮肤的真皮层中,在AD患者的病损皮肤中数量增加并且呈现激活状态,提示ILC2参与了AD的发生发展过程。本文就ILC2在AD中作用机制的研究进展做一综述。
Arresting supporters: targeting neutrophils in metastasis

It is becoming increasingly clear that leukocytes dynamically regulate cancer progression and metastasis, and among leukocytes, granulocytic cells abundantly accumulate in metastatic organs; however, their function in metastasis remains controversial. In a recent report in Nature, Wculek and Malanchi clarify the role of mature neutrophils as mediators of metastatic initiation and provide a targeted approach to prevent the pro-metastatic activity of neutrophils in breast cancer models.
心血管疾病的精准医疗实践与思考

自美国总统奥巴马在2015年国情咨文演讲中提出了“精准医疗计划” (precision medicine initiative)后,精准医疗已成为眼下医学界最受关注和热议的时代概念。该计划致力于治愈癌症和糖尿病等疾病,目的是加快在基因组层面对疾病的精准认识和针对性治疗。精准医疗是以个体化医疗为基础,基因组学、蛋白质学、生物信息学及大数据科学等多学科交叉应用而发展起来的新型医学诊疗模式。现就精准医疗在某些儿童心血管疾病中的实践与研究现状以及未来发展模式思考如下。

Evaluation of Hypervisor Stability towards Insider Attacks

Virtualization technology plays a key role in cloud computing. Thus, the security issues of virtualization tools (hypervisors, emulators, etc.) should be under precise consideration. However, threats of insider attacks are underestimated. The virtualization tools and hypervisors have been poorly protected from this type of attacks. Furthermore, hypervisor is one of the most critical elements in cloud computing infrastructure. Firstly, hypervisor vulnerabilities analysis is provided. Secondly, a formal model of insider attack on hypervisor is developed. Consequently, on the basis of the formal attack model, we propose a new methodology of hypervisor stability evaluation. In this paper, certain security countermeasures are considered that should be integrated in hypervisor software architecture.
Uncover the Aesthetic Simplicity Associated with Mass Transfer in Energy Materials

Aesthetics, referred frequently to as a philosophical term, has played a starring role in forming and evolving a number of aspects of human society, including arts, politics, economics, ethics, etc. Indeed, exploring and investigating the aesthetic phenomena in the scientific field have aroused insightful research findings, which in turn has stimulated research interests in such a science-aesthetics field. In particular, better-evaluated aesthetic aspects of the materials field are expected to be uncovered upon the exceedingly-exposed fundamental breakthroughs in researching the basic structure and functionality of materials. In this report, we glimpse into the aesthetic simplicity of energy materials and comprehend specifically the mass transfer functionalities of key categories of energy materials through an intuitive and bottom-up approach. Our effort aspires to shed new lights on the functionality understanding and manipulation of functional materials in general.
A High Speed Autofocusing System for Micro System Applications

In this paper, we present a high speed autofocus system for micro system applications and design a look-up-table based autofocusing algorithm for applications when a target object is always visible, e.g., manufacturing parts with alignment fiducials. We perform an evaluation of 24 focus measures to verify that which focus measure is the best for the look-up-table based method. From the evaluation, we find that the Chebyshev moments-based focus measure (CHEB) is the most suitable. Furthermore, we also develop a look-up-table based autofocus system that uses CHEB as the focus measure. In training phase, we offline construct a table from training images of an object that are captured at several lens distances. Each entry of table consists of focus measure computed from image and lens distance. In working phase, given an input image, the algorithm first computes the focus measure and then finds the best match focus measure from the table and looks up the corresponding lens position for moving it into the in-focus position. Our algorithm can perform autofocusing within only 2 steps of lens moving. The experiment shows that the system can perform high speed autofocusing of micro objects.
Middle-Upper Ordovician (Darriwilian-Early Katian) Positive Carbon Isotope Excursions in the Northern Tarim Basin, Northwest China: Implications for Stratigraphic Correlation and Paleoclimate

Three positive carbon isotope excursions are reported from Middle-Upper Ordovician in Tahe oil-gas field, northern Tarim Basin. Based on conodont biostratigraphy, the Middle Darriwilian Isotope Carbon Excursion (MDICE) and the Guttenberg Carbon Isotope Excursion (GICE) are identified from Darriwilian to Early Katian by the aid of whole-rock carbon isotope data from two well cores. Positive excursion within conodont Pygodus anserinus zone is developed in Early Sandbian, and the fluctuation range is no less than MDICE. Because the range of this excursion in the generalized global carbon isotope curve is short, previous studies paid little attention to it, and named Early Sandbian Isotope Carbon Excursion (ESICE) in this paper. Furthermore, these positive excursions are not directly related to sea level fluctuations and the MDICE and GICE identified in northern Tarim can be globally correlated to that in southern China, North America, South America, and Europe. The Saergan Fm. source rocks of Middle-Upper Ordovician in Kalpin Dawangou outcrop are in accord with the geologic time of MDICE and ESICE, and GICE have strong ties to the source rock of Lianglitag Fm. in basin. Abundant organic carbon burial is an important factor in genesis of positive isotope carbon excursions. Positive oxygen isotope excursion, conodont fauna turnover, decreased conodont total diversity, and the change of sedimentary facies indicated that dramatic changes of paleoceanographic environment of Early-Middle Ordovician in Tarim Basin started from the end of Darriwillian, and an obvious icehouse climate of Late Ordovician occurred in ESICE.
Early-Middle Cambrian Palynomorph Microfossils and Related Geochemical Events in South China

The earliest Cambrian acritarch 'Asteridium-Heliosphaeridium-Comasphaeridium' assemblage and the Early Cambrian ('Chiungchussuan') acritarch 'Skiagia ornate-Fimbriaglomerella membranacea' assemblage in South China can be correlated with assemblages from synchronous strata elsewhere in the world. Recent geochemical study and biomarker evidence further confirm a biostratigraphic change between Cambrian Series 2 and Series 3 and support the recognition of a major geological and biotic event during this time interval.
The Pre-Sturtian Negative δ~(13)C Excursion of the Dajiangbian Formation Deposited on the Western Margin of Cathaysia Block in South China

The Dajiangbian Formation in South China is a siliciclastic-dominated sedimentary succession with low-grade metamorphism deposited on the western margin of the Cathaysia Block, and is capped by a glaciogenic diamictite (the Sizhoushan Formation). The Sizhoushan glaciogenic strata can be attributed to the Jiangkou glacial (Sturtian glacial) episode as they share stratigraphic and lithological similarities with Jiangkou strata in South China. Some carbonate, chert and shale units throughout the upper part of the Dajiangbian Formation were sampled for carbonate carbon isotope (δ~(13)C_(carb)) and organic carbon isotope (δ~(13)C_(org)) analyses. A range of geochemical indices including oxygen isotopes (δ~(18)O) and Mn/Sr (Fe/Sr) ratios suggest that primary carbon isotope values were preserved in the upper Dajiangbian Formation. The upper Dajiangbian Formation shows δ~(13)C_(carb) of -0.1‰, upward decreasing towards to -5.4‰. We suggest that the negative δ~(13)C excursion beneath the Sizhoushan diamictite is correlative with the Pre-Sturtian Islay δ~(13)C_(carb) anomaly and allows correlation with the global Neoproterozoic isotope stratigraphy. We find that carbonate and organic carbon isotope data of the upper Dajiangbian Formation are coupled, consistent with the δ~(13)C_(carb)-δ~(13)C_(org) pattern observed on multiple continents.
Materials Research Advances towards High-Capacity Battery/Fuel Cell Devices(Invited paper)

The world has entered an era featured with fast transportations, instant communications, and prompt technological revolutions, the further advancement of which all relies fundamentally, yet, on the development of cost-effective energy resources allowing for durable and high-rate energy supply. Current battery and fuel cell systems are challenged by a few issues characterized either by insufficient energy capacity or by operation instability and, thus, are not ideal for such highly-demanded applications as electrical vehicles and portable electronic devices. In this mini-review, we present, from materials perspectives, a few selected important breakthroughs in energy resources employed in these applications. Prospectives are then given to look towards future research activities for seeking viable materials solutions for addressing the capacity, durability, and cost shortcomings associated with current battery/fuel cell devices.
Organic practices and gender are effective strategies to provide healthy pork loin

This study evaluated the influence of husbandry (organic feed and management but not free-ranging vs. conventional) and sex (barrows vs. gilts) on pork meat quality. A total of 60 Longissimus thoracis pork muscle samples from different 3-way crossbred genotypes were chosen from 3 conventional and 2 organic pig farms. Technological meat quality was measured at 24 h post-mortem and muscle fatty acid content and composition was analysed by gas chromatography. The loin from organic pigs at 24 h of retail display had lower pH, but it had no detrimental effects on drip loss. All the International Commission on Illumination colour attributes except meat lightness differed between husbandry systems. Moisture and crude protein content were lower whereas intramuscular fat content was greater in organic than in conventional pork. Total saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), polyunsaturated fatty acid (PUFA) and PUFA n-6 contents did not differ between husbandry systems, but total PUFA n-3 (mainly C18:3 n-3) were greater in organic than in conventional pork. Sex did not affect ultimate pH or meat colour attributes but barrows showed lower moisture and greater intramuscular fat than gilts. Total SFA and MUFA content were similar but all the PUFA (both n-6 and n-3) were lower in barrows than in gilts. These results suggest that some bioactive compounds from dietary origin, i.e., linolenic acid (C18:3 n-3) content from dietary vegetable oils (soybean or olive olein), might be used to highlight the nutritive value of (not free-ranging) organic pork meat. In addition, gilts were leaner than barrows and showed a more favourable PUFA/SFA ratio.
Charactering protein fraction concentrations as influenced by nitrogen application in low-glutelin rice cultivars

To optimize both grain yield and quality of low-glutelin rice cultivars under N-fertilizer strategies, two-year field experiments involving three low-glutelin rice cultivars (W1240, W1721, W025) and an ordinary rice cultivar (H9405) with five N treatments were carried out to determine the effects of N application rate and genotype on protein fractions contents and Glutelin/Prolamin ratio (Glu/Pro). The difference of protein fraction concentrations affected by N application rate existed in genotypes. Ordinary rice cultivar had a larger increase in glutlein concentration affected by N application rate than low-glutelin rice cultivars did. Glutelin in H9405 had a increase of 30.6 and 41.0% under the N4 treatment (360 kg N ha~(–1)) when compared with N0 treatment (no fertilizer N) in 2010 and 2011 respectively, while all the low-glutelin rice cultivars showed relatively smaller increases for two years. Variance analysis showed no significant effect of N application rate on glutelin in W1240 and W025 while the effects on albumin, globulin and prolamin were significant in low-glutelin rice. What’s more, N treatment had no significant influence on Glu/Pro ratios in low-glutelin rice cultivars while a significant increase in Glu/Pro ratio was observed in ordinary rice cultivar. So low-gultelin rice cultivars showed a different pattern from ordinary rice cultivars when influenced by N application rate.
