Gap analysis on open data interconnectivity for disaster risk research

Open data strategies are being adopted in disaster-related data particularly because of the need to provide information on global targets and indicators for implementation of the Sendai Framework for Disaster Risk Reduction 2015–2030. In all phases of disaster risk management including forecasting, emergency response and post-disaster reconstruction, the need for interconnected multidisciplinary open data for collaborative reporting as well as study and analysis are apparent, in order to determine disaster impact data in timely and reportable manner. The extraordinary progress in computing and information technology in the past decade, such as broad local and wide-area network connectivity (e.g. Internet), highperformance computing, service and cloud computing, big data methods and mobile devices, provides the technical foundation for connecting open data to support disaster risk research. A new generation of disaster data infrastructure based on interconnected open data is evolving rapidly. There are two levels in the conceptual model of Linked Open Data for Global Disaster Risk Research (LODGD) Working Group of the Committee on Data for Science and Technology (CODATA), which is the Committee on Data of the International Council for Science (ICSU): data characterization and data connection. In data characterization, the knowledge about disaster taxonomy and data dependency on disaster events requires specific scientific study as it aims to understand and present the correlation between specific disaster events and scientific data through the integration of literature analysis and semantic knowledge discovery. Data connection concepts deal with technical methods to connect distributed data resources identified by data characterization of disaster type. In the science community, interconnected open data for disaster risk impact assessment are beginning to influence how disaster data are shared, and this will need to extend data coverage and provide better ways of utilizing data across domains where innovation and integration are now necessarily needed.

肠道菌群在多囊卵巢综合征代谢异常中的作用

多囊卵巢综合征(polycystic ovary syndrome,PCOS)是育龄期女性最常见的一种生殖功能障碍与代谢异常并存的疾病,患病率约为5% ~ 10%。本病的危害已远不止于月经失调和不孕等生殖问题,更严重的是还存在远期并发症的风险,如肥胖、2型糖尿病、抑郁等。然本病的生殖系统问题往往容易及时就诊,而相关代谢疾病常因其发展缓慢等因素易被忽视。近些年,许多生殖内分泌机构也陆续更新本病的诊治共识或建议,均认为应将PCOS代谢异常等并发症纳入PCOS诊治之内,故早期筛查并干预PCOS代谢异常显得尤为必要。有研究表明肠道菌群失调可以引起多种代谢性疾病的发生发展。探讨肠道菌群在PCOS代谢异常中的作用,为本病的发病机制研究和相关临床治疗提供新的突破。

Deep Structure and Metallogenic Processes of the Altai- Junggar-Tianshan Collage in Southern Altaids

The Altai-Junggar-Tianshan collage in southern Altaids is an important metallogenic domain in Central Asia that contain world-class copper-iron-nickel deposits. As an accretionary-type metallogenic system, the metallogenic processes of the Altai-Junggar-Tianshan collage is essential in understanding the genetic mechanism of ore deposits in general. Here in this paper we present a brief introduction to the project on the western part of the Southern Altaids, entitled “The deep structure and metallegenic processes of the North China accretionary metallogenic systems”.This project mainly focuses on the deep structure and metallogenic background of the Altai-Junggar-Tianshan collage by integrated studies from field geology, structural mapping, geochemistry and geophysical exploration. Multiple new geological and geophysical methods will be applied to make transparency of the Kalatongke and Kalatage ore clusters. This will update our understanding of the geodynamic processes of metallogenesis and lead to the development and foundation of new metallogenic theories in accretionary orogens.
Heading control strategy assessment for coaxial compound helicopters

The coaxial compound helicopter has two possible strategies for heading control: collective differential and rudder deflection. A flight dynamics model is developed to assess the effect of different heading control strategies. This includes the trim characteristics, steady flight performance, controllability, and manoeuvrability. The trim study demonstrates that heading control strategies are less influential on trim results, and the steady flight performance is also not significantly affected by the heading control strategy adopted. The controllability analysis shows although heading bandwidth and phase delay results at various speeds with different heading control strategies are all satisfied, the control derivative of the collective differential decreases as speed increases, and its heading aggressive agility is degraded into Level 3 in high-speed flight. In addition, using collective differential would lead to severe heading-rolling coupling as forward speed increases. On the contrary, the control derivative and aggressive agility of the rudder deflection is improved with forward speed, and there is no evidence of heading-rolling coupling. Finally, the transient turn Mission- Task-Element(MTE) is utilized to investigate the heading manoeuvre characteristics in different heading control strategies, which indicates that the collective differential would add the amplitude of control input and the power consumption during this MTE.
起源于神经纤维瘤1型的恶性外周神经鞘膜瘤1例报道并文献复习

神经纤维瘤病(neurofibromatosis, NF)是一种较为常见的多系统受累的常染色体显性遗传性疾病,其发病原因尚不十分清楚,可能与胚胎发育早期神经嵴细胞分化异常和某些变异有关。 1987年美国国立卫生研究院(NIH)将其分为周围型(NF1)和中枢型(NF2),其中NF1型较常见。恶性外周神经鞘膜瘤(malignant peripheral nerve sheath tumors, MPNST)起源于周围神经或显示神经鞘不同成分分化的梭形细胞肉瘤,比较少见,曾称恶性雪旺氏瘤、神经源性肉瘤、神经纤维肉瘤。2002年WHO将其统称为MPNST,约占软组织肉瘤的3%~10%,其中近半数病例有NF1病史,低于10%的患者发病与放疗有关。本文报道1例双侧大腿NF1进展为MPNST病例的病理组织学特征及免疫组织化学结果,复习相关文献来探讨MPNST的诊断及鉴别诊断。

Sestrin2/3在有氧运动改善骨骼肌胰岛素抵抗中的作用研究进展

机体组织细胞对胰岛素敏感性降低引发组织糖摄取和利用效率下降,即临床常见的胰岛素抵抗(insulin resistance,IR)。许多代谢相关疾病如肥胖、2型糖尿病(type 2diabetes mellitus,T2DM)、血脂代谢紊乱等患者均存在不同程度的IR。有氧运动因其具有促进机体能量代谢、改善细胞胰岛素信号敏感性等特点,目前已成为临床防治代谢性相关疾病的重要干预手段之一。应激诱导蛋白Sestrin(Sesn)2/3的缺失导致机体自发产生IR,Sens2/3通过其抗氧化功能和mTORC1(mammalian target of rapamycin complex 1,mTORC1)的抑制作用维持细胞代谢稳态从而调控骨骼肌细胞糖摄取,而有氧运动本身也能影响Sesns的蛋白表达。因此,深入探究运动对Sesns的影响可为临床运动疗法防治IR等代谢相关疾病提供理论依据。

Branchiogenic carcinoma in the parotid gland

An 89-year-old male patient was referred to the Department of Otolaryngology, Head & Neck Surgery, West China Hospital because of a painless mass in the right parotid region for 8 years which had grown rapidly over the most recent 6 months. Physical examination revealed that the mass was 4.5 cm ×6.0 cm in dimensions. Enhanced computed tomography demonstrated a solid cystic tumor with irregular margin in the right parotid gland [Figure 1A and 1B]. Total parotidectomy was performed under general anesthesia. Surgical exploration revealed that the tumor had an uneven thickness capsule with mixture of brown liquid and necrotic solids in it. Fortunately, facial nerve branches were not embedded in the tumor thus spared. Several enlarged lymph nodes were collected in the superior right neck. Histopathologically, the cyst lining was composed of ciliated columnar and squamous epithelium, and the latter cells multifocally evolved into atypical proliferation, which then led to the formation and the microinvasiveness of squamous cell carcinoma. Moreover, extensive necrosis in the parotid gland was also observed [Figure 1C and 1D]. Immunohistochemically, the tumor cells were positive for P63, P53, pancytokeratin (PCK), and P40. The percentage of MIB-1 positive cells was 20%. In situ hybridization of Epstein- Barr encoding region (EBER) turned out to be negative. The diagnosis of branchiogenic carcinoma was established. No lymphatic metastasis was detected. Postoperative radiotherapy was recommended to the patient but was not adopted. The patient was eventless during the postoperative 2-year follow-up.

Dielectric metasurfaces for distance measurements and three-dimensional imaging

Ultrathin metasurfaces have shown the capability to influence all aspects of light propagation. This has made them promising options for replacing conventional bulky imaging optics while adding advantageous optical properties or functionalities. We demonstrate that such metasurfaces can also be applied for single-lens three-dimensional(3-D) imaging based on a specifically engineered point-spread function(PSF). Using Huygens' metasurfaces with high transmission, we design and realize a phase mask that implements a rotating PSF for 3-D imaging. We experimentally characterize the properties of the realized double-helix PSF, finding that it can uniquely encode object distances within a wide range. Furthermore, we experimentally demonstrate wide-field depth retrieval within a 3-D scene, showing the suitability of metasurfaces to realize optics for 3-D imaging, using just a single camera and lens system.
Using Raman shift and FT-IR spectra as quality indices of oil bit PDC cutters

Nowadays many of oil and gas wells are drilled extensively by Polycrystalline Diamond Compact (PDC) drill bits. Various companies are manufacturing PDC cutters according to their usage. All of these companies concentrate their products of PDC cutters to be well resisting for abrasive wear. The wear of PDC inserts leads to money loss as well as delays the drilling procedures causing unexpected dilemmas. Therefore, it is crucially significant to evaluate the quality of the PDC cutters based on their resistance against abrasive wear. The present work concentrates on assessing the PDC cutters from various sources using two non-destructive analytical approaches: Raman-Shift and Fourier Transformation Infrared Ray (FT-IR) spectra. The analysis of the PDC samples with the analytical techniques were validated with the previous experimental results obtained from micro and nano-scratch tests achieved on the same specimens. The presented work could be performed on many PDC cutters from various manufacturers as the applied tests considered non-destructive compared to the traditional destructive techniques which leads the way for evaluating lots of PDC cutters without causing any damage. The analysis of the applied analytical approaches agreed with the results obtained from previous experimental scratch tests.
General criterion for intersection between hydraulic induced fractures and pre-existing natural fractures

Pre-existing natural fractures and other structurally weak planes are usually well-developed in unconventional reservoirs. When such fractures intersect with hydraulic induced fractures, they will redirect and propagate as an important mechanical principle of volume fracturing by the formation of complex fracture networks. Under the shadow effect of natural fractures and other structurally weak planes with hydraulic supported fracture stress, hydraulic fractures do not fully propagate in the direction of the maximum horizontal-principal-stress. This paper computed the stress intensity factors of hydraulic fracture types I and II by integrating the various interactions, established universally-applicable mechanical principles for the propagation behavior when a hydraulic fracture propagating in an arbitrary direction intersects with a natural fracture at an arbitrary angle, and demonstrated the mechanical principles of the intersection between hydraulic induced fractures and pre-existing natural fractures. This study proved the following conclusions: as the intersection angle between the hydraulic fracture and the maximum horizontal-principal-stress increased, the possibility of the hydraulic fracture being captured by the natural fracture with an identical approaching angle first increased and then decreased; as the net stress increased, the intersection behavior between the hydraulic fracture and the natural fracture transitioned from penetration to capture.
Sand transport in multiphase flow mixtures in a horizontal pipeline: An experimental investigation

An inherent problem with both oil and natural gas production is the deposition of sand particles in pipeline, which could lead to problems such as excessive pressure drops, equipment failure, pipeline erosion, and production decline. The characterization of sand particles transport and sedimentation in different flow systems such as sandemultiphase mixtures is vital to predict the sand transport velocity and entrainment processes in oil and gas transportation pipelines. However, it seems that no model exists able to accurately characterize the sand transport and deposition in multiphase pipeline. In fact, in the last decade several researchers tried to extend the modeling of liquid-solid flow to gas-liquid-solid flow, but no significant results have been obtained, especially in slug flow condition due to the complexity of the phenomenon. In order to develop and validate a mathematical model properly formulated for the calculation of the sand critical deposition velocity in gas-liquid flow, more and more experimental data are necessary. This paper presents a preliminary experimental study of three phase flows (air-water-sand) inside a horizontal pipe and the application of the sand-liquid models present in literature. Significant observations were made during the experimental study from which several conclusions were drawn. Different sand flow regimes were established by physical observation and data analysis: fully dispersed solid flow, moving dunes and stationary bed. The critical deposition velocities were determined at different sand concentrations. It was concluded that sand transport characteristics and the critical deposition velocity are strongly dependent on the gas-liquid flow regime and on sand concentration.

A modified predictive model for estimating gas flow rate in horizontal drain hole

Accurate prediction of the flow rate of horizontal gas well is necessary for economic feasibility, planning and development of gas field. Most of the early models assumed that the production from the horizontal well is infinitely conductive except few recent models. Some recent models reported in the literature for estimating flow rate in horizontal well where the pressure losses due to friction along horizontal drain hole was considered. An improved model that checks the impact of all possible well bore pressure losses on gas production rate of horizontal well is reported. The neglected impact of well bore pressure losses due to fluid accumulation and kinetic energy in the past models is thought to be a conceivable reason for the inconsistency between computed rates from the models and rates got from production tests. The new model was validated using the same field contextual investigation utilized by Guo et al. and outcome got from the new model yields more satisfactory results. A more realistic results that evident all flow phenomena in gas well include the initial unsteady, pseudo-steady and steady state flow condition hence flow rate at any given production time has been established for flow of gas along horizontal well. The outcomes of the study demonstrate that the percentage deviation of the new model at steady state flow condition is less than 5.0% compared with 11.05% acquired from Guo et al. model following by 259.7% from Furui's model, and 1118.2% got from Joshi's model. This work gives field operators a precise and helpful device for prediction and assessment of production in a gas horizontal well.
A new method used for reservoir production performance analysis

Water flooding type-curves, recently receiving increasing attentions, play an essential role in evaluation of OOIP and prediction of future production. The study proposed a method modified form Weibull model and water flooding type-curves to analyze the reservoir production performance, including predication of oil production and water injection rates. The results indicate that the method can estimate and provide solutions for oil production, water injection rate and injection-production ratio with a well accuracy. A case study is conducted to demonstrate the applicability and accuracy of model by field data. The matching results illustrate a good accordance between calculated values and field data.
A study of the performance of the LSWA CO_2 EOR technique on improvement of oil recovery in sandstones

Low salinity water is an emerging enhanced oil recovery (EOR) method that causes wettability alteration towards a favorable state to reduce residual oil saturation, while water alternating gas (WAG) is a proven EOR process that enhances oil recovery by controlling mobility of both water and gas. Therefore, combining the two EOR processes as low salinity water-alternating CO_2 EOR injection (LSWA CO_2) can further improve oil recovery by promoting the synergy of the mechanisms underlying these two methods. Core flooding experiments, contact angle, interfacial tension (IFT), and CO_2 solubility measurement in oil and brine were conducted to investigate the viability and performance of LSWA CO_2 in sandstone reservoirs. A favorable wettability alteration, along with IFT reduction and mobility control, are the mechanisms that contribute to residual oil mobilization efficiencies during the LSWA CO_2 EOR process. In addition, LSWA CO_2 core flooding experiments result in a significant incremental oil recovery. Three smart waters were tested in our research, to examine the impact of changing cationic composition on oil recovery. The solutions are designed brines as NaCl (SW1), MgCl2 (SW2), and KCl (SW3). Of the three solutions, SW1 yields the highest incremental oil recovery and highest IFT reduction. In addition, it results in a favorable wettability alteration towards a more water-wet state. In all cases, introducing CO_2 to the brine/oil system shows a great advantage in terms of enhancing wettability modification, promoting IFT reduction, and controlling the displacement front of the injected fluid through mobility control.
DeepCount: Crowd Counting with Wi-Fi Using Deep Learning

The ubiquitous Wi-Fi devices and recent research efforts on wireless sensing have led to intelligent environments which can sense people's locations and activities in a device-free manner. However, current works are mostly designed for single human environment owing to the complexity of multiple human environments, the limited bandwidth of Wi-Fi and in turn, greatly hinder this technology from the real implementation. To realize such device-free sensing in multiple human environments, the first step-stone is to estimate how many targets or in other words crowd counting in a closed environment, which is not only the basis for multiple human environmental sensing but also leads to many potential applications such as crowd control. To this end, we propose DeepCount-a solution using deep learning approach to infer the number of people in an indoor environment with Wi-Fi signals. Our scheme is based on the key intuition that, although with great complexity, the deep learning approaches can somehow be able to build a complex function to fit the correlation between the number of people and channel state information values. Furthermore, to alleviate the inadequate amount of data required and improve the adaptability of the deep learning approach, we add an online transfer learning approach, which utilizes the entering/leaving results to fine-tune the deep learning model. The prototype of Deep-Count is implemented and evaluated on the commercial Wi-Fi device. By the massive training samples, our deep learning model is able to estimate the number of crowd up to 5 with the mean accuracy of 82.3% by this end-to-end learning approach. Meanwhile, by using the amendment mechanism of the activity recognition model to judge door switch to get the variance of the crowd to amend deep learning predicted results, the accuracy is up to 87% in a rather effective manner.
