Possibilities of urban flood reduction through distributed-scale rainwater harvesting

Urban flooding in Chittagong City usually occurs during the monsoon season and a rainwater harvesting (RWH)system can be used as a remedial measure. This study examines the feasibility of rain barrel RWH system at a distributed scale within an urbanized area located in the northwestern part of Chittagong City that experiences flash flooding on a regular basis. For flood modeling,the storm water management model (SWMM)was employed with rain barrel low-impact development (LID)as a flood reduction measure. The Hydrologic Engineering Center's River Analysis System (HEC-RAS)inundation model was coupled with SWMM to observe the detailed and spatial extent of flood reduction. Compared to SWMM simulated floods,the simulated inundation depth using remote sensing data and the HEC-RAS showed a reasonable match,i.e.,the correlation coefficients were found to be 0.70 and 0.98,respectively. Finally,using LID,i.e.,RWH,a reduction of 28.66% could be achieved for reducing flood extent. Moreover,the study showed that 10%e60% imperviousness of the subcatchment area can yield a monthly RWH potential of 0.04e0.45 m~3 from a square meter of rooftop area. The model can be used for necessary decision making for flood reduction and to establish a distributed RWH system in the study area.
Effects of water application intensity of micro-sprinkler irrigation and soil salinity on environment of coastal saline soils

To achieve the greatest leaching efficiency,water movement must occur under unsaturated flow conditions. Accordingly,the water application intensity of irrigation must be chosen carefully. The aim of this study was to evaluate the impact of the water application intensity of micro-sprinkler irrigation on coastal saline soil with different salt contents. To achieve this objective,a laboratory experiment was conducted with three soil salinity treatments (2.26,10.13,and 22.29 dS/m)and three water application intensity treatments (3.05,5.19,and 7.23 mm/h). The results showed that the effect of soil salinity on soil water content,electrical conductivity,and pH was significant,and the effect of the water application intensity was insignificant. High soil water content was present in the 40e60 cm profile in all soil salinity treatments,and the content was higher in the medium and high water application intensity treatments than in the low-intensity treatment. Significant salt leaching occurred in all treatments,and the effect was stronger in the high soil salinity treatment and medium water application intensity treatment. In the medium and high soil salinity treatments,pH exhibited a decreasing trend,with no trend change in the low soil salinity treatment,and the pH value was higher in the medium water application intensity treatment than in the other two treatments. These results indicated that the three intensities evaluated had no statistically different effect on the electrical conductivity of saturated soil-paste extracts (E_C)in the upper 20 cm of the soil profile,and it would be better to maintain a lower value of the water application intensity.

目的探讨妊娠期高血压疾病患者血清富亮氨酸重复序列相互作用蛋白(LRRFIP)、血小板活化因子(PAF)的表达及相关性。方法选择2017年4月至2018年5月在武汉市第四医院接诊的55例妊娠期高血压疾病患者,其中妊娠期高血压组20例,轻度子痫前期组23例,重度子痫前期组12例,并同期选择在本院接受体检的健康体检者53例作为对照组,比较两组受试者及不同严重程度妊娠期高血压患者血常规、血清LRRFIP、PAF的表达情况。结果四组身体质量指数、舒张压、收缩压、血小板计数(PLT)、血小板平均体积(MPV)、血小板聚集率(PagT)、血小板分布宽度(PDW)、血清LRRFIP、PAF比较差异有统计学意义(P <0.05);随着疾病严重程度的加重,PLT不断降低,MPV、PagT、PDW、血清LRRFIP、PAF逐渐升高,差异有统计学意义(P <0.05);经Spearman相关分析结果显示,血清LRRFIP、PAF与舒张压、收缩压、MPV、PDW均呈正相关,和PLT呈负相关(P <0.05)。结论血清LRRFIP、PAF在妊娠期高血压疾病患者中有明显高表达,可通过促血小板活化对血管内皮造成损伤,使血压水平升高,加重患者的病情。
中国淹溺性心脏停搏心肺复苏专家共识

淹溺又称溺水(submersion),指是人淹没与浸润于水或其他液体介质中并受到伤害的状况;淹溺的严重情况为溺死(drowning),淹溺性心搏骤停或心脏停搏(drowning cardiac arrest, DCA)是淹溺最严重的临床过程。据不完全统计,我国每年有5万余人死于淹溺,而在青少年意外伤害致死的事故中,平均每年有近3万名儿童死于淹溺,淹溺已成为其第一死因;故淹溺是急诊重要的理化损伤综合征之一。需要强调的是,实际上溺水(内涵为水的环境)为坊间俗称,在医学上严格称为淹溺(内涵为发病过程),因为患者淹溺的环境,不但有“水”的作用,还有其他溶质的作用,故在抢救这些患者时,应注意环境的影响;不慎跌入粪坑、污水池和化学物贮槽时,可引起皮肤、黏膜损害甚至全身中毒,故DCA有其临床特殊性,相对应的心肺复苏(cardiopulmonary resuscitation, CPR)也应有其自身的理论体系,因此制定规范的DCA心肺复苏方案至关重要。
胃-十二指肠梗阻合并胆道梗阻的支架治疗

胃-十二指肠梗阻合并胆道梗阻是进展期转移性肿瘤累及十二指肠及胆总管所致,此类病灶因无法手术切除常常选择内镜下姑息治疗,而放置自膨胀金属支架是解除解剖梗阻有效的姑息治疗手段。根据十二指肠梗阻部位与十二指肠大乳头的位置关系,可将梗阻分为3类,其相对应的最佳放置支架的方法有所不同。临床上胃-十二指肠梗阻与胆道梗阻发生顺序的差异也会影响支架的放置策略。本文归纳近期文献,对上述不同情况下支架的放置提供临床参考。
空肠原发性腺鳞状细胞癌1例

空肠原发性鳞状细胞癌的发病机制尚不明确,有以下3种可能的发病机制:(1)异位鳞状上皮恶变;(2)黏膜中存在的多潜能干细胞能够分化为腺癌和鳞癌;(3)黏膜慢性损伤导致腺上皮鳞状化生,在鳞化的基础上进一步发生癌变;也有文献报道,肠道鳞状细胞癌的发生可能与肠道的慢性炎性反应和HPV感染有关。有研究表明,由于鳞癌细胞在短时间内增殖较快,侵袭性强,因此,在腺鳞癌中,鳞癌成分可能对肿瘤的进展和预后有一定的影响。本例患者就诊时已处于中晚期,由于肿瘤体积较大,侵犯周围脏器,可见脉管和神经组织累犯,肠系膜淋巴结可见转移性癌,术后未给予任何辅助治疗,现随访中。
肺纤毛黏液结节性乳头状肿瘤5例临床病理分析

目的探讨肺纤毛黏液结节性乳头状肿瘤(ciliated muconodular papillary tumor,CMPT)的临床病理学特征、诊断及鉴别诊断。方法回顾性分析5例肺CMPT的临床病理、免疫表型、分子生物学特征及预后,并复习相关文献资料。结果患者年龄30 ~ 77岁(平均52岁),其中女性3例,男性2例,均为体检时发现肺外周部结节。眼观:肿瘤境界欠清。镜检:以基底细胞、纤毛柱状细胞和黏液细胞乳头状增生为主,可见少量腺管样结构及黏液湖形成。免疫表型:纤毛柱状细胞呈CK7、TTF-1阳性;基底细胞表达p63、p40及CK5/6;黏液细胞可弱阳性表达TTF-1和CK7;三类细胞Ki-67增殖指数均较低(1% ~ 2%)。随访1 ~ 36个月(平均18个月)均未见肿瘤复发或转移。结论肺CMPT是罕见的肺原发良性/低度恶性潜能肿瘤,生物学行为惰性。在诊断工作中,特别是在术中快速冷冻诊断时极易与原发或继发肺黏液性腺癌相混淆。仔细寻找典型的CMPT形态学特点并辅以免疫组织化学染色有助于诊断和鉴别诊断。

盆腔脏器脱垂是一种发病率高、且严重影响女性生活质量的非致死性疾病。经阴道植入聚丙烯网片是临床常用的治疗方法,但其不良反应限制了广泛应用,目前寻找有更好组织相容性的移植物迫在眉睫。干细胞治疗可改善组织相容性,极大程度地减少不良炎症反应,是盆腔脏器脱垂极有前景的治疗手段。本文总结了间充质干细胞与网片相互作用的相关研究,根据现有的研究结果评估干细胞的治疗潜能。干细胞治疗有望成为增强盆底组织的有效工具。
合并椎管内异常的早发性脊柱侧凸矫形手术的安全性

目前,脊柱外科学界已普遍认同脊柱矫形手术是严重早发性脊柱侧凸(EOS)患者唯一有效的治疗策略,其中脊柱融合手术和生长棒技术是最常见的手术方案。EOS患者行脊柱矫形术前应予以全面的影像学检查、仔细的神经系统查体以及时发现可能伴发的椎管内异常。对于无进展性神经损害证据的EOS患者,在不预防性神经外科手术的情况下行生长棒植入和后续撑开手术并不明显增加患者医源性神经损害的风险。

Research and.modeling on.correlation among.microstructure, yield strength and.process of.bainite/martensite steel

The contributions of different strengthening mechanisms to yield strength of bainite/martensite multiphase rail steel with different finish cooling temperatures in the controlled cooling process were quantitatively investigated. Dislocation density and substructure size of the rail steel were measured by scanning electron microscopy, electron backscatter diffraction and X-ray diffraction. The results show that the dislocation density increases with the decrease in block width in rail steel. Based on the correlation among dislocation density, block width and yield strength, a physical model was proposed to predict the yield strength of rail steel. The variation of block width and dislocation density in different positions of rail head microstruc-ture was integrated with temperature field simulation. Dislocation density and block width reveal significant correlations with the finish cooling temperature.
Characterization of.hot deformation behavior of.30Si2MnCrMoVE low.alloying ultra.high.strength steel by.constitutive equations and.processing maps

Isothermal compression tests of as-forged 30Si2MnCrMoVE low-alloying ultra-high-strength steel were carried out on a Gleeble 3500 thermal simulator at the deformation temperatures of 950–1150.°C and strain rates of 0.01–10 s~(-1). Based on the classical stress–dislocation density relationship and the kinematics of the dynamic recrystallization, the constitutive equations of the work hardening dynamical recovery period and dynamical recrystallization period were developed by using the work hardening curve and Avrami equation, which shows good agreement with the experimental value. Processing maps at the strain of 0.90 were constructed based on dynamic material model and were analyzed combined with microstructure observation under different conditions. The optimum parameter based on the processing maps was obtained and verified by a supplementary experiment. The power dissipation maps and instability maps at strains of 0.05–0.90 were also constructed, and the evolution law was analyzed in detail. The established constitutive equation and hot processing maps can provide some guidance for hot working process.
Occurrence and transfer of heavy metals in sediments and plants of Aegiceras corniculatum community in the Qinzhou Bay, southwestern China

Mangrove wetlands can reduce heavy metal pollution by trapping heavy metals. In this study, the concentration, transport and bioaccumulation of Cr, Cd, Cu, Zn and Pb in the sediments and different parts of Aegiceras corniculatum at four different sites in the Qinzhou Bay in southwestern China were investigated. The results showed that although the potential ecological risk of all five heavy metals was slight, the concentration of Cr was at a moderate pollution level due to the emissions of industries and aquaculture waste water. Core sediment records indicated that the concentrations of heavy metals at the depth of 0–20 cm were relatively high, showing an increasing trend of heavy metals over the past 20–30 years. Cr, Cu, Pb and Cd accumulated mainly in the roots of A. corniculatum, while Zn accumulated mainly in the stems. Aegiceras corniculatum showed the strongest transport capacity for Zn and Cu and the strongest bioaccumulation ability for Cd. Compared with other mangrove communities, A. corniculatum can be chosen as a restoration species in tropical and subtropical coastal zones polluted by Zn, Cu and Cd.
Wavelength-selective 2 × 2 optical switch based on a Ge_2Sb_2Te_5-assisted microring

A novel wavelength-selective 2 × 2 optical switch based on a Ge_2Sb_2Te_5 (GST)-assisted microring-resonator (MRR) is proposed. The present GST-assisted MRR consists of two access optical waveguides and an MRR coupled with a bent GST-loaded silicon photonic waveguide. The 2 × 2 optical switch is switched ON or OFF by modifying the GST state to be crystalline or amorphous. In particular, the microring waveguide and the bent GST-loaded waveguide are designed to satisfy the phase-matching condition when the GST is crystalline. As a result, the MRR becomes highly lossy and the resonance peak is depressed significantly. On the other hand, when it is off, there is little coupling due to the significant phase mismatching. Consequently, one has a low-loss transmission at the drop port for the resonance wavelength. In this paper, the simulation using the three-dimensional finite-difference method shows that the extinction ratio of the designed photonic switch is ∼20 dB at the resonance wavelength, while the excess losses at the through port and drop port are 0.9 dB and 2 dB. In particular, the resonance wavelength changes little between the ON and OFF states, which makes it suitable for multichannel wavelength-division-multiplexing systems.
Subwavelength thick ultrahigh-Q terahertz disc microresonators

Artificial structures that exhibit narrow resonance features are key to a myriad of scientific advances and technologies. In particular, exploration of the terahertz (THz) spectrum—the final frontier of the electromagnetic spectrum—would greatly benefit from high-quality resonant structures. Here we present a new paradigm of terahertz silicon disc microresonators with subwavelength thickness. Experimental results utilizing continuouswave THz spectroscopy establish quality factors in excess of 120,000 at 0.6 THz. Reduction of the disc thickness to a fraction of the wavelength reduces the losses from the silicon substrate and paves the way to unparalleled possibilities for light–matter interaction in the THz frequency range.
Karyomorphology of three endemic plants (Brassicaceae: Euclidieae and Arabideae) from the Qinghai-Tibet Plateau and its significance

In the paper, chromosome number and karyotype of three endemic genera from China are reported for the first time. Our results show that Anzhengxia yechengnica has a karyotype formula 2n = 2x = 14 = 6 m + 8sm and belongs to Stebbins-3A; Shangrilaia nana karyotype formula is 2n = 2x = 14 = 10 m + 4sm (2sat) and belongs to Stebbins-1A; Baimashania pulvinata karyotype formula is 2n = 2x = 16 = 12 m (2sat) + 4sm and belongs to Stebbins-1A. Anzhengxia and Shangrilaia are monospecific genera belonging to tribe Euclidieae and both have a basic chromosome x = 7. Baimashania, which belongs to tribe Arabideae, has two species which have a basic chromosome x = 8. The implications of these cytological data are compared with morphological support and the implications for each tribe are discussed. We also summarize chromosomal number variation and its systematic implications of two tribes from the Qinghai-Tibet Plateau.
Genetic structure, gene flow pattern, and association analysis of superior germplasm resources in domesticated upland cotton (Gossypium hirsutum L.)

Gene flow patterns and the genetic structure of domesticated crops like cotton are not well understood. Furthermore, marker-assisted breeding of cotton has lagged far behind that of other major crops because the loci associated with cotton traits such as fiber yield and quality have scarcely been identified. In this study, we used 19 microsatellites to first determine the population genetic structure and patterns of gene flow of superior germplasm resources in upland cotton. We then used association analysis to identify which markers were associated with 15 agronomic traits (including ten yield and five fiber quality traits). The results showed that the upland cotton accessions have low levels of genetic diversity (polymorphism information content = 0.427), although extensive gene flow occurred among different ecological and geographic regions. Bayesian clustering analysis indicated that the cotton resources used in this study did not belong to obvious geographic populations, which may be the consequence of a single source of domestication followed by frequent genetic introgression mediated by human transference. A total of 82 maker-trait associations were examined in association analysis and the related ratios for phenotypic variations ranged from 3.04 %to 47.14%. Interestingly, nine SSR markers were detected in more than one environmental condition. In addition, 14 SSR markers were co-associated with two or more different traits. It was noteworthy that NAU4860 and NAU5077 markers detected at least in two environments were simultaneously associated with three fiber quality traits (uniformity index, specific breaking strength and micronaire value). In conclusion, these findings provide new insights into the population structure and genetic exchange pattern of cultivated cotton accessions. The quantitative trait loci of domesticated cotton identified will also be very useful for improvement of yield and fiber quality of cotton in molecular breeding programs.
CDK4/6 inhibition blocks cancer metastasis through a USP51-ZEB1 -dependent deubiquitination mechanism

Tumor metastasis is the most common cause of cancer-related deaths,yet it remains poorly understood.The transcription factor zinc-finger E-box binding homeobox 1(ZEB1)is involved in the epithelial-to-mesenchymal transition(EMT)and plays a pivotal role in tumor metastasis.However,the underlying mechanisms of the posttranslational modification of ZEB1 remain largely unknown.Herein,we demonstrated that specific inhibition of CDK4/6 was able to block tumor metastasis of breast cancer by destabilizing the ZEB1 protein in vitro and in vivo.Mechanistically,we determined that the deubiquitinase USP51 is a bona fide target of CDK4/6.The phosphorylation and activation of USP51 by CDK4/6 is necessary to deubiquitinate and stabilize ZEB1.Moreover,we found a strong positive correlation between the expression of p-RB(an indicator of CDK4/6 activity),p-USP51 and ZEB1 in metastatic human breast cancer samples.Notably,the high expression of p-RB,p-USP51,and ZEB1 was significantly correlated with a poor clinical outcome.Taken together,our results provide evidence that the CDK4/6-USP51-ZEB1 axis plays a key role in breast cancer metastasis and could be a viable therapeutic target for the treatment of advanced human cancers.
Drp1-dependent remodeling of mitochondrial morphology triggered by EBV-LMP1 increases cisplatin resistance

Latent membrane protein 1(LMP1)is a major Epstein-Barr virus(EBV)-encoded oncoprotein involved in latency infection that regulates mitochondrial functions to facilitate cell survival.Recently,mitochondrial fission has been demonstrated as a crucial mechanism in oncovlrus-mediated carcinogenesis.Mitochondrial dynamin-related protein 1(Drpl)-mediated mitochondrial fission has an impact on the chemoresistance of cancers.However,the mechanism by which oncogenic stress promotes mitochondrial fission,potentially contributing to tumorigenesis,is not entirely understood.The role of Drp1 in the oncogenesis and prognosis of EBV-LMP1-positive nasopharyngeal carcinoma(NPC)was determined in our study.We show that EBV-LMP1 exhibits a new function in remodeling mitochondrial morphology by activating Drp1.A high level of p-Drp1(Ser616)or a low level of p-Drp1(Ser637)correlates with poor overall survival and disease-free survival.Furthermore,the protein level of p-Drp1(Ser616)is related to the clinical stage(TNM stage)of NPC Targeting Drp1 impairs mitochondrial function and induces cell death in LMP1-positive NPC cells.In addition,EBV-LMP1 regulates Drp1 through two oncogenic signaling axes,AMPK and cyclin Bl/Cdkl,which promote cell survival and cisplatin resistance in NPC.Our findings provide novel insight into the role of EBV-LMP1-driven mitochondrial fission in regulating Drpl phosphorylation at serine 616 and serine 637.Disruption of Drp1 could be a promising therapeutic strategy for LMP1-positive NPC.
Thermal lens analysis in a diode-pumped 10 Hz 100 mJ Yb:YAG amplifier

We address the power scaling issue in end-pumped laser rod amplifiers by studying, experimentally and numerically, the magnitude of thermal lensing in a high-energy diode-pumped Yb:YAG crystal. The spatio-temporal temperature profile of the gain medium and the focal length of the induced thermal lens are determined numerically. The influence of the repetition rate and pumping power on the temperature distribution is analyzed. Experimental measurements covered repetition rates between 1 and 10 Hz and up to 4 kW pumping power.
Projection of residential and commercial electricity consumption under SSPs in Jiangsu province, China

Future electricity consumption may increase due to climate change, but the amplitude depends on the interaction between many uncertain mechanisms. Based on the linear model and policy model, the residential and commercial electricity consumption in Jiangsu province are projected under the shared socioeconomic pathways (SSPs). The linear model considers climate and socioeconomic factors, and the policy model also takes policy factors into account. We find that the cooling degree days (CDD) coefficient is about 3 times of heating degree days (HDD), which reflects that the cooling demand is much larger than heating, and also shows in the projection. The results of the policy model are generally lower than the linear model, which is the impact of policy factors. For example, the SSP1 and SSP2 of the policy model are 320 TW h and 241.6 TW h lower than the linear model in 2100, respectively. At the end of the 21st century, the residential and commercial electricity consumption in Jiangsu province will reach 107.7-937.9 TW h per year, 1.3-11.6 times of 2010. The SSP1 scenario under the policy model is based on feasible assumptions, and can be used as the target scenario for policymakers to establish energy intensity reduction targets.
The policy-driven peak and reduction of China's carbon emissions

Pursuant to the Paris Agreement, China committed itself to peak its carbon emissions by around 2030 and to increase the non-fossil share of primary energy to 20% at the same time. The government has supported the international agreement by setting and strengthening the domestic policy targets for an earlier peak and faster reduction, aiming to contain the average global temperature increase to well below 2 ℃. We develop a Kaya Inequality method to assess the time of peak and pace of reduction of China's energy-related CO_2 emissions based on the national energy policy targets for 2030.We find that, despite the minor fluctuations, the current plateau essentially represents the peak emissions and should enter a phase of steady decline by around 2025, given current trends in energy consumption and decarbonization. Such developments would be consistent with the strengthened national policy target to achieve 50% of renewable power generation by 2030. However, the basic policy targets e a 20% share of non-fossil energy and 6 Gtce in total energy consumption by 2030 e would be insufficient to peak carbon emissions by around 2030. The synergy and interplay between domestic policy target setting and international climate commitments shed light on the need to elevate national climate ambitions under the Paris Agreement and beyond.
A pilot study of catching high-z GRBs and exploring circumburst environment in the forthcoming SVOM era

Rapid spectroscopy of GRB afterglows is an important and hard task. Based on the archival XSGRB spectral database, we here perform a pilot study on the afterglow's spectroscopy in the forthcoming SVOM era in two aspects. First, our simulation indicates that the color acquired from the SVOM/VT blue and red channels is effective in discriminating between low-z (z ≲ 3) and distant GRB candidates until z ~ 6. Second, by doubling the sample size, we find that the previously proposed global photoionization response of the circumburst gas to the prompt emission (i.e., the CIV/CII-Liso/E2peak relationship) is roughly confirmed, although the confirmation is dissatisfactory at the large Liso/E2peak end. We believe that this issue can be further addressed in the SVOM era by a larger spectroscopy sample, thanks to its capability of rapid identification of optical candidates of afterglow and its anti-solar pointing strategy.
A Receiver-Forwarding Decision Scheme Based on Bayesian for NDN-VANET

Named Data Network(NDN)has caused wide concerns in VANET community because NDN uses a content-centric mechanism that naming content rather than the host.However, integrating NDN into VANET(NDN-VANET)also faces several challenges including consumer/provider mobile, broadcast storm problem and so on.In this paper, we propose a Bayesian-based Receiver Forwarding Decision(BRFD)scheme to mitigate the broadcast storm problem incurred by interest packets in NDN-VANET.In the BRFD, vehicles received an interest packet are required to make forwarding decisions based on Bayesian decision theory according to current network conditions obtained by neighbor interaction.However, the receiver-forwarding decision in BRFD can also cause a conflict issue because multiple vehicles forward copies of the same packet at the same time.So a back-off mechanism is introduced in BRFD.Experimental results show that the BRFD algorithm has better performance in several aspects in contrast to probability-based forwarding scheme and “bread crumb” routing.
