讨论介入手术穿刺动脉时,需给予小剂量肝素抗凝,以避免血栓形成。激活全血凝固时间(ACT)是监测肝素效果的常用指标。当ACT未达到预期水平时称为肝素抵抗,可导致动脉血栓形成,处理不及时可致肢体缺血坏死。正常人群单次予肝素50U/kg,ACT可达200s以上。肝素抵抗患者ACT常不达标,多见于感染、DIC、肝胆疾病、左房粘液瘤等,与抗凝血酶Ⅲ(AT-Ⅲ)活性、肝素应用史、高血小板血症等相关。AT-Ⅲ活性正常为70%~130%,<70%时与肝素抵抗密切相关。Plt异常活跃可释放血小板第Ⅳ因子(PF4),具有中和肝素作用,Plt>300×109/L与肝素抵抗明显相关。本例术前Plt 533×10~9/L,无肝素应用史,静推和持续泵注肝素25~50U/kg,ACT<200s,未达到预期值,可诊断为肝素抵抗,这在心导管等微创手术中少见。肝素抵抗的应对措施包括详细了解病史,完善检查,对Plt偏高、可疑 AT-Ⅲ减少的患者应警惕,常规行ACT监测。发生抗凝后 ACT值不达标,可追加肝素剂量并加用PGI_2、阿司匹林等其他抗凝药,输注新鲜冰冻血浆或浓缩AT-Ⅲ制剂,延期手术等。若形成血栓需尽快溶栓。本例术毕监测右足SpO_2,持续观察右下肢皮温、肤色,及时发现血栓并抗凝溶栓,无严重并发症。
Mechanical properties of carbon fiber/cellulose composite papers modified by hot-melting fibers

Carbon fiber (CF)/cellulose (CLS) composite papers were prepared by papermaking techniques and hot-melting fibers were used for modification. The mechanical properties of the obtained composite papers with different CF, CLS and hot-melting fiber ratios were studied and further discussed. It is observed that, for both CF/CLS composite papers and those modified by hot-melting fibers, the normal stress firstly increases and then declines with the addition of carbon fibers. The results also show that with the addition of hot-melting fibers, the modified papers exhibit enhanced mechanical performance compared to CF/CLS composite papers. Through SEM characterization, it is confirmed that the improvement of mechanical properties attributes to the reinforcement of adhesive binding at the fiber overlap nodes. Also, through four-probe method, the resistivity and the electrical performance of the modified and unmodified papers were characterized and the result shows that the hot-melting fiber modification brings no harm to the electrical properties.

A facile electrochemical method for the synthesis of new sulfonamide derivatives of potential biological significance

The electrochemical synthesis of some new sulfonamide derivatives was carried out via the electrochemical oxidation of 2,3-dihydrophthalazine-1,4-dione (1) in the presence of arylsulfinic acids (2a and 2b) as nucleophiles. The results show that, the electrogenerated phthalazine-1,4-dione (1ox) participates in a Michael type addition reaction with 2a or 2b and via an EC mechanism to produce the corresponding sulfonamide derivatives. This method provides a one-pot procedure for the synthesis of new sulfonamide derivatives of potential biological significance in good yields without using toxic reagents at a carbon electrode in an environmentally friendly manner.
Photoelectrochemical properties of MWCNT-TiO_2 hybrid materials as a counter electrode for dye-sensitized solar cells

The MWCNT-TiO_2 hybrid materials were prepared by a simply mixing method and used as a counter electrode (CE) for dye-sensitized solar cells. Compared with the platinum CE, MWCNT-TiO_2 CE has the similar redox voltage and current response in the cyclic voltammetry. The electrochemical catalytic activity was characterized by the electrochemical impedance spectroscopy and Tafel curve, including the equivalent circuit, the exchange current density, the limiting diffusion current density, and the diffusion coefficient of triiodide/iodide redox species. The results indicate that the reduction process from triiodide to iodide is determined by the kinetic-controlled and diffusion-limited processes. The device performance is optimal based on the MWCNT-TiO_2 (mass ratio of 2:1) CE, such as the open-circuit voltage of 0.72 V, the short-circuit photocurrent density of 15.71 mA/cm~2, the fill factor of 0.68, and the photon-to-electron conversion efficiency of 7.69%.

OUTSOURCING DECISION AND ORDER POLICY WITH FORECAST UPDATING UNDER CAPACITY RESERVATION CONTRACT

This paper investigates an optimal decision problem in a single-period, two-stage supply chain with capacity reservation contract. At the beginning of the planning horizon, the retailer, who faces stochastic demand, reserves future capacity according to his forecasting of the demand. The supplier then constructs capacity. At the beginning of the selling season, the retailer updates the demand forecasting and places an order. When the retailer’s demand is greater than the supplier’s capacity, the supplier can meet the retailer’s demand by outsourcing. We analyze the optimal decision of each player in both centralized and decentralized systems. Furthermore, under the case in which demand follows a uniform distribution, we obtain the closed-form optimal strategies of each player for both centralized and decentralized systems and conduct numerical studies to reveal additional conclusions. The numerical studies show that the optimal reservation capacity for the retailer and the optimal constructing capacity for the supplier in the decentralized system are both less than the optimal constructing capacity in the centralized system. Furthermore, we also find that the profit loss due to decentralization always exists and increases in indeterminacy.
卡塔格内综合征合并IgA肾病一例

讨论卡塔格内综合征(Kartagener syndrome)是以慢性鼻窦炎、支气管扩张、全内脏转位三联征为特点的常染色体隐性遗传病。本病属于原发性纤毛运动障碍(primary ciliary dyskinesia, PCD)的一种亚型,约占 PCD患者的一半,人群发病率约1/22 000,近亲结婚的发病率明显增加,男女发病比例无差异。人体纤毛广泛存在于上呼吸道、下呼吸道、乳突腔、鼓窦、鼓室、咽鼓管、输卵管、精子鞭毛、脑室等,这些部位的纤毛属于动纤毛(motile cilia),其规律摆动推动液体流动而发挥生理作用,PCD患者因编码纤毛蛋白或组装这些蛋白的基因缺陷导致纤毛结构或功能异常,引起相应临床症状。PCD患者多在15岁前发病,反复出现鼻窦炎、中耳炎、支气管炎,逐渐发展为慢性鼻窦炎、鼻息肉、慢性中耳炎、支气管扩张、反复肺部感染等。由于精子鞭毛失去摆动能力、纤毛异常的输卵管无法保证卵子的正常输送,引起男性不育及女性出现异位妊娠甚至不孕。母体妊娠10~ 15 d时,胚胎异常的纤毛无法引导胚胎向右螺旋旋转,内脏的定向转位变为随机转位,因此估计约50%的PCD患者可出现内脏转位。通常内脏转位不引起临床症状,但6%的PCD患者合并其他先天性内脏缺陷,如房间隔缺损、室间隔缺损、多脾、无脾等。约20%~25%内脏转位患者合并有支气管扩张和鼻窦炎。其他临床表现包括脑积水、视网膜炎、幽门狭窄、尿道裂、唇裂、聋哑等,但与PCD之间的关系仍缺乏认识。本病例自幼反复鼻窦炎、肺部感染,影像学也提示支气管扩张、双侧鼻窦炎、全内脏镜像转位,符合卡塔格内综合征诊断。

Rock Damage Structure of the South Longmen-Shan Fault in the 2008 M8 Wenchuan Earthquake Viewed with Fault-Zone Trapped Waves and Scientific Drilling

This article is to review results from scientific drilling and fault-zone trapped waves (FZTWs) at the south Longman-Shan fault (LSF) zone that ruptured in the 2008 May 12 M8 Wenchuan earthquake in Sichuan, China. Immediately after the mainshock, two Wenchuan Fault Scientific Drilling (WFSD) boreholes were drilled at WFSD-1 and WFSD-2 sites approximately 400 m and 1 km west of the surface rupture along the Yinxiu-Beichuan fault (YBF), the middle fault strand of the south LSF zone. Two boreholes met the principal slip of Wenchuan earthquake along the YBF at depths of 589-m and 1230-m, respectively. The slip is accompanied with a 100-200-m-wide zone consisting of fault gouge, breccia, cataclasite and fractures. Close to WFSD-1 site, the nearly-vertical slip of ~4.3-m with a 190-m wide zone of highly fractured rocks restricted to the hanging wall of the YBF was found at the ground surface after the Wenchuan earthquake. A dense linear seismic array was deployed across the surface rupture at this venue to record FZTWs generated by aftershocks. Observations and 3-D finite-difference simulations of FZTWs recorded at this cross-fault array and network stations close to the YBF show a distinct low-velocity zone composed by severely damaged rocks along the south LSF at seismogenic depths. The zone is several hundred meters wide along the principal slip, within which seismic velocities are reduced by ~30–55% from wall-rock velocities and with the maximum velocity reduction in the ~200-m-wide rupture core zone at shallow depth. The FZTW-inferred geometry and physical properties of the south LSF rupture zone at shallow depth are in general consistent with the results from petrological and structural analyses of cores and well log at WFSD boreholes. We interpret this remarkable low-velocity zone as being a break-down zone during dynamic rupture in the 2008 M8 earthquake. We examined the FZTWS generated by similar earthquakes before and after the 2008 mainshock and observed that seismic velocities within fault core zone was reduced by ~10% due to severe damage of fault rocks during the M8 mainshock. Scientific drilling and locations of aftershocks generating prominent FZTWs also indicate rupture bifurcation along the YBF and the Anxian-Guangxian fault (AGF), two strands of the south LSF at shallow depth. A combination of seismic, petrologic and geologic study at the south LSF leads to further understand the relationship between the fault-zone structure and rupture dynamics, and the amplification of ground shaking strength along the low-velocity fault zone due to its waveguide effect.
Pressure-temperature Evolution of the Metapelites in the Motuo Area, the Eastern Himalayan Syntaxis

The Motuo area is located in the east of the Eastern Himalayan Syntaxis. There outcrops a sequence of high-grade metamorphic rocks, such as metapelites. Petrology and mineralogy data suggest that these rocks have experienced three stages of metamorphism. The prograde metamorphic mineral assemblages (M_1) are mineral inclusions (biotite + plagioclase + quartz ± sillimanite ± Fe-Ti oxides) preserved in garnet porphyroblasts, and the peak metamorphic assemblages (M_2) are represented by garnet with the lowest X_(Sps) values and the lowest X_(Fe#) ratios and the matrix minerals (plagioclase + quartz ± Kfeldspar + biotite + muscovite + kyanite ± sillimanite), whereas the retrograde assemblages (M_3) are composed of biotite + plagioclase + quartz symplectites rimming the garnet porphyroblasts. Thermobarometric computation shows that the metamorphic conditions are 562–714°C at 7.3–7.4 kbar for the M_1 stage, 661–800°C at 9.4–11.6 kbar for the M_2 stage, and 579–713°C at 5.5–6.6 kbar for the M_3 stage. These rocks are deciphered to have undergone metamorphism characterized by clockwise P-T paths involving nearly isothermal decompression (ITD) segments, which is inferred to be related to the collision of the India and Eurasia plates.
The wave motion over a submerged Jarlan-type perforated breakwater

The wave motion over a submerged Jarlan-type breakwater consisting of a perforated front wall and a solid rear wall was investigated analytically and experimentally. An analytical solution was developed using matched eigenfunction expansions. The analytical solution was confirmed by previously known solutions for single and double submerged solid vertical plates, a multidomain boundary element method solution, and experimental data. The calculated results by the analytical solution showed that compared with double submerged vertical plates, the submerged Jarlan-type perforated breakwater had better wave-absorbing performance and lower wave forces. For engineering designs, the optimum values of the front wall porosity, relative submerged depth of the breakwater, and relative chamber width between front and rear walls were 0.1–0.2, 0.1–0.2, and 0.3–0.4, respectively. Interchanging the perforated front wall and solid rear wall may have no effect on the transmission coefficient. However, the present breakwater with a seaside perforated wall had a lower reflection coefficient.
Validation of the “HY-2” altimeter wet tropospheric path delay correction based on radiosonde data

Wet tropospheric path delay (PD) is a highly variable term for the altimeter measurement of a sea surface height, caused by the refraction effect of atmospheric water vapor and cloud liquid water. In order to estimate PD values, the “HY-2” system includes a calibration microwave radiometer (CMR) operating at 18.7, 23.8 and 37 GHz. The PD data of the CMR were compared and validated by coincident radiosonde profiles from ten globally distributed radiosonde stations during October 2011 to August 2012. The temporal interval was 1 h. In order to avoid land contamination, different spatial intervals between these two data sets were tested. The empirical fit function of PD uncertainty and spatial interval was found and extrapolated to the ideal situation that the data of CMR and radiosonde were totally coincident. The stability of the brightness temperature of the CMR and its impact on the PD correction was also studied. Consequently, the uncertainty of the PD algorithm of the CMR was estimated to be 2.1 cm.
Coastal wind field retrieval from polarimetric synthetic aperture radar

Coastal winds are strongly influenced by topology and discontinuity between land and sea surfaces. Wind assessment from remote sensing in such a complex area remains a challenge. Space-borne scatterometer does not provide any information about the coastal wind field, as the coarse spatial resolution hampers the radar backscattering. Synthetic aperture radar (SAR) with a high spatial resolution and all-weather observation abilities has become one of the most important tools for ocean wind retrieval, especially in the coastal area. Conventional methods of wind field retrieval from SAR, however, require wind direction as initial information, such as the wind direction from numerical weather prediction models (NWP), which may not match the time of SAR image acquiring. Fortunately, the polarimetric observations of SAR enable independent wind retrieval from SAR images alone. In order to accurately measure coastal wind fields, this paper proposes a new method of using co-polarization backscattering coefficients from polarimetric SAR observations up to polarimetric correlation backscattering coefficients, which are acquired from the conjugate product of co-polarization backscatter and cross-polarization backscatter. Co-polarization backscattering coefficients and polarimetric correlation backscattering coefficients are obtained form Radarsat-2 single-look complex (SLC) data.The maximum likelihood estimation is used to gain the initial results followed by the coarse spatial filtering and fine spatial filtering. Wind direction accuracy of the final inversion results is 10.67 with a wind speed accuracy of 0.32 m/s. Unlike previous methods, the methods described in this article utilize the SAR data itself to obtain the wind vectors and do not need external wind directional information. High spatial resolution and high accuracy are the most important features of the method described herein since the use of full polarimetric observations contains more information about the space measured.This article is a useful addition to the work of independent SAR wind retrieval. The experimental results herein show that it is feasible to employ the co-polarimetric backscattering coefficients and the polarimetric correlation backscattering coefficients for coastal wind field retrieval.
The bimodality of the Luzon Strait deep water

Combined conductivity-temperature-depth (CTD) casts and Argo profiles, 3 086 historical hydrocasts were used to quantify the water column characteristics in the northern South China Sea (SCS) and its adjacent waters. Based on a two-dimensional “gravest empirical mode” (GEM), a gravitational potential (o, a vertically integrated variable) was used as proxy for the vertical temperature profiles T_G(p, o). o integrated from 8 MPa to the surface shows a close relationship with the temperature, except in the deep layer greater than 15 MPa, which was caused by the bimodal deep water in the region. The GEM temperature profiles successfully revealed the bimodality of the Luzon Strait deep water, that disparate hydrophic vertical profiles can produce distinct specific volume anomaly (δ) in the SCS and the western Philippine Sea (WPS), but failed in the Luzon Strait, where different temperature profiles may produce a same δ. A significant temperature divergence between the SCS water and the WPS water confirmed that the bimodal structure is strong. The deepwater bifurcation starts at about 15 MPa, and gets stronger with increasing depth. As the only deep channel connecting the bimodal-structure waters, water column characteristics in the Luzon Strait is in between, but much closer to the SCS water because of its better connectivity with the SCS. A bimodal temperature structure below 15 MPa reveals that there was a persistent baroclinic pressure gradient driving flow through the Luzon Strait. A volume flux predicted through the Bashi Channel with the hydraulic theory yields a value of 5.62×10~6 m~3/s using all available profiles upstream and downstream of the overflow region, and 4.03×10~6 and 2.70×10~6 m~3/s by exclusively using the profiles collected during spring and summer, respectively. No volume flux was calculated during autumn and winter because profiles are only available for the upstream of the Bashi Channel during the corresponding period.

Traffic Labeller: Collecting Internet Traffic Samples with Accurate Application Information

Traffic classification research has been suffering from a trouble of collecting accurate samples with ground truth. A model named Traffic Labeller (TL) is proposed to solve this problem. TL system captures all user socket calls and their corresponding application process information in the user mode on a Windows host. Once a sending data call has been captured, its 5-tuple {source IP, destination IP, source port, destination port and transport layer protocol}, associated with its application information, is sent to an intermediate NDIS driver in the kernel mode. Then the intermediate driver writes application type information on TOS field of the IP packets which match the 5-tuple. In this way, each IP packet sent from the Windows host carries their application information. Therefore, traffic samples collected on the network have been labelled with the accurate application information and can be used for training effective traffic classification models.
Reputation-Based Hierarchically Cooperative Spectrum Sensing Scheme in Cognitive Radio Networks

Cooperative spectrum sensing in cognitive radio is investigated to improve the detection performance of Primary User (PU). Meanwhile, cluster-based hierarchical cooperation is introduced for reducing the overhead as well as maintaining a certain level of sensing performance. However, in existing hierarchically cooperative spectrum sensing algorithms, the robustness problem of the system is seldom considered. In this paper, we propose a reputation-based hierarchically cooperative spectrum sensing scheme in Cognitive Radio Networks (CRNs). Before spectrum sensing, clusters are grouped based on the location correlation coefficients of Secondary Users (SUs). In the proposed scheme, there are two levels of cooperation, the first one is performed within a cluster and the second one is carried out among clusters. With the reputation mechanism and modified MAJORITY rule in the second level cooperation, the proposed scheme can not only relieve the influence of the shadowing, but also eliminate the impact of the PU emulation attack on a relatively large scale. Simulation results show that, in the scenarios with deep-shadowing or multiple attacked SUs, our proposed scheme achieves a better tradeoff between the system robustness and the energy saving compared with those conventionally cooperative sensing schemes.
