Analysis of the impact of urbanization on regional flood risk: A case study in the Qinhuai River Basin, China

Qinhuai River Basin is located in the lower reaches of Yangtze River. With acceleration of urbanization, the flood risk of basin has increased and threatened blood and treasure of people. Based on RS and GIS methods, the impact of urbanization on the flood risk was analyzed in space and time. The study showed that, 1) Urbanization aggravated the flood risk. The space distribution of urbanization and flood risk showed consistency. 2) From 1994 to 2001, the flood risk of south of Nanjing city proper and areas along Yangtze River increased. From 2001 to 2008, areas of increased flood risk migrated upwards along Qinhuai mainstream. Until 2008, the flood risk along Qinhuai mainstream was higher. 3) The flood prevention pressure of Nanjing city proper and new urban region of Jiangning district augmented. Construction and control of integrated water conservancy project should be strengthened and meteorological forecast ability should be promoted.

The information gathered by these tools is quite useful in software development, testing, debugging, simulation and optimization. SEntre is such an instrumentation system with the features of efficiency, ease-to-use interface, transparency and comprehensiveness. To obtain good performance, we employ instrumentation while copying (IWC) mechanism. The interface provided by SEntre is very simple but powerful. User can develop different tools based on SEntre. To illustrate SEntre's versatility, we describe two tools, one is used to obtain memory access address and the other is an extremely fast simulator.
Minería de opiniones mediante análisis de sentimientos y extracción de conceptos en Twitter

Debido al auge de las redes sociales en los ultimos anos, han surgido diversas tecnicas de analisis de sentimientos y mineria de datos que les son utiles a las empresas para conocer la opinion publica de sus productos. Sin embargo, la mayoria de las aplicaciones en el mercado que realizan analisis de sentimientos orientados a productos se centran en la opinion sobre el producto en general, y pocas tratan de buscar por que las opiniones son positivas o negativas. Un sistema que descubra como se perciben en las redes las caracteristicas de un producto ademas de la percepcion del producto en si, tambien puede ayudar a cualquier organizacion a detectar la percepcion que tienen de ella y por que. El objetivo de este trabajo es desarrollar un sistema que, usando el entorno de computo distribuido Apache Spark, y mediante tecnicas de analisis de sentimientos y de extraccion de conceptos consiga averiguar la percepcion general de los usuarios de Twitter de los distintos componentes, cualidades y caracteristicas definidas en una jerarquia de entidades definidas por el usuario.
Primula dermatitis: prevalence, detection and outcome

patient did general duties, mvolvmg cleamng outside the spray booth. He then became a spray pamter, a JOb which he earned out without mcident for 2 months. A new work procedure to mcrease recovery of excess pamt was then mstituted, whereby pamters entered the booth at the end of the workshift to dislodge pigments from the mside walls with scrapers and air hoses. This clean-up resulted m much more direct skm exposure than the spraymg itself. Withm 2 weeks of starting this new clean-up, the patient developed severe dermatitis of the ears, forehead, penoral skm and cheeks near the eyes, where pigment concentrated around the margms oflus halfface cartndge respirator and paper hood, which reqmred treatment with predmsone. Returnmg to work as a spray pamter provoked Similar episodes of dermatitis, also mvolvmg the neck, antecubital fossae, and forearms. Patch testing was performed with the Amencan Academy of Dermatology standard senes (which mcluded bisphenol A epoxy) and I% dilutions of his powder pamt pigments, reading at 48 and 96 h and grading by the method of the North Amencan Contact Dermatitis Group (2). I + reactiOns were observed at 48 h to the polyester pigments, mcreasmg to 2 + by 96 h. These pigments con tamed approximately 5% (by weight) tnglycidyiisocyanurate, described by the manufacturer as a polyfunctwnal epoxy resm used to cross-link the polyester pigments upon heat activation. The bisphenol A epoxy m the standard senes was negative. The 2 pnncipal constituents of the pamt, polyester and techmcal grade tnglycidyl Isocyanurate, were obtamed from the manufacturer. Pigment colonzers were not tested, smce earlier patch testing mdicated that all pamts reacted, regardless of pigment color. Tnglycidyiisocyanurate (0.5% pet.) produced a 2+ reaction at both 48 and 96 h; polyester resm (1% pet.) was negative. Patch tests to tnglycidylisocyanurate on 3 volunteer controls without dermatitis were negative. Tnglycidyl Isocyanurate IS listed as a mild skm sensitizer m gumea pigs on the manufacturer's matenal safety data sheets. A literature survey found no previOus reports of human Irritation or allergy. No chemical analysis was performed to exclude the possibility that sensitization could have been due to a contammant or byproduct m the techmcal grade matenal. A follow-up VISit to the company Identified several work practices among employees where modificatiOns could substantially reduce skm exposure m the spray pamt operation. Most notably, the cleanup was changed so that workers no longer used a1r hoses mside the booths, thus elimmating unnecessary airborne exposure.
A simple all MOS voltage reference for RFID applications

In recent years Radio Frequency Identification (RFID) systems have become very popular in a number of applications. RFID is an example of mixed signal integrated circuit. Voltage reference is an important circuit for various modules like power generation unit, data converter units of RFID. The basic requirement of reference circuits is a simple architecture with low power consumption and high stability. In this work we are proposing the reference circuit in which output voltage is based on the difference between the gate-source voltages of two NMOS transistors. The proposed voltage reference circuit generates a simulated reference voltage of 610mV with a temperature coefficient of 10.5 ppm/°C for the temperature range of -40°C to 110°C. The maximum power consumption of the proposed circuit is 3μW simulated at a supply voltage of 2V. The line regulation is 0.25mV/V for the supply voltage range from 1.25V to 2V and the PSRR@100Hz is 69 to 75dB. The proposed circuit is implemented using a 180nm standard CMOS technology.
Binary Linear Programming Model in Solving Bus Crew Problem as Tactical Fixed Task Scheduling

In this paper, we consider a crew scheduling problem (CSP) of bus transportation with the objective of minimizing the cost of crew members. We address a different time frame and different type of crew members. The maximum total working limit for each type of crew member has been set. The problem can be formulated as a Tactical Fixed Task Scheduling Problem (TFTSP) where the ready time and due date of the tasks are fixed in advance. A Binary Linear Programming (BLP) model is used to obtain an optimal solution for the problem. We conduct a testing and implement the model using LINGO 17.0 software. Results of the computational testing give optimum values for the problem. Hence, a feasible crew scheduling is obtained.
Corticobasal syndrome associated with a novel 1048_1049insG progranulin mutation

Mutations in the progranulin gene ( GRN ) cause familial frontotemporal lobar degeneration (FTLD) associated with type 3 TDP-43 positive inclusions.1 The clinical phenotype associated with progranulin mutations continues to be defined, although patients present usually with either behavioural symptoms (behavioural variant FTLD) or a progressive aphasia. However, patients have also been described with a corticobasal syndrome (CBS), extending the pathological associations of this disorder into the TDP-43 proteinopathies.1 Neuroanatomically, CBS is usually associated with asymmetrical frontal and parietal lobe deficits, and there is evidence that progranulin mutations are also associated with early parietal lobe involvement and asymmetrical hemispheric atrophy.2 We describe a novel mutation in the GRN gene causing a CBS in family DRC219. This family was originally described as having “familial dementia lacking specific pathological features presenting with clinical features of corticobasal degeneration” in Brown et al . 3 DRC219 is a family from the south of England with a history of an autosomal dominant dementia. The proband was seen and investigated at the National Hospital for Neurology and Neurosurgery, Queen Square, London, UK. Her grandmother died aged 61 and had been said to have abnormal behaviour for a few years prior to death. Her mother died aged 54, with the onset of memory and behavioural problems in her 40s, as well as a left hemiparesis. The proband’s brother also had a progressive behavioural syndrome with symptoms of inappropriate social behaviour …
A New Class of Optimal High-Order Strong-Stability-Preserving Time Discretization Methods

Strong-stability-preserving (SSP) time discretization methods have a nonlinear stability property that makes them particularly suitable for the integration of hyperbolic conservation laws where discontinuous behavior is present. Optimal SSP schemes have been previously found for methods of order 1, 2, and 3, where the number of stages s equals the order p. An optimal low-storage SSP scheme with s=p=3 is also known. In this paper, we present a new class of optimal high-order SSP and low-storage SSP Runge--Kutta schemes with s>p. We find that these schemes are ultimately more efficient than the known schemes with s=p because the increase in the allowable time step more than offsets the added computational expense per step. We demonstrate these efficiencies on a set of scalar conservation laws.
Previous Experience and Reproductive Investment of Female Columbian Ground Squirrels

Abstract Reproductive success of females in iteroparous species usually increases early in life, then remains constant or declines. The restraint hypothesis suggests that primiparous females limit their 1st reproduction in order to avoid future costs to survival, reproduction, or both, whereas constraint indicates that primiparous females are limited in their 1st reproductive attempt either because they lack sufficient resources (measured by body mass) or lack experience at weaning a litter. To evaluate these alternatives, we examined age- and experience-related patterns of reproduction in female Columbian ground squirrels (Spermophilus columbianus) with data from a long-term study and by experimentally altering age at 1st reproduction. In the results of the long-term study, experienced females had significantly higher reproductive investment and reproductive success (number of offspring surviving to yearling age) compared to inexperienced females. Annual survival of females was not affected by their level of previous weaning experience or current reproductive investment. Additionally, subsequent reproductive success was not impaired by earlier reproduction. In the experimental results, experienced females had significantly higher reproductive investments compared to inexperienced females. Constraint in terms of previous weaning experience best explained the differences in reproductive investment and reproductive success between primiparous and multiparous females.
Angiotensin‐(1‐7) Prevents Angiotensin II‐induced Fibrosis in Cremaster Microvessels

The effect of the heptapeptide hormone Ang‐(1‐7) on microvascular fibrosis in rats with Ang II‐induced hypertension was investigated, since vascular fibrosis/remodeling plays a prominent role in hypertension‐induced end‐organ damage and Ang‐(1‐7) inhibits vascular growth and fibrosis.
Near Field Service Initiation via Vibration Channel

In this paper, we propose a Near Field Pairing Service system called NFV to enable group communication. This system leverages common mobile device, e.g., smartphones, equipped with motion sensors. A group of people can put their mobile devices on the table and setup a secure connection via a vibration-propagation based key delivery scheme. In this way, NFV is able to transmit a secure connection key among a group of trusted mobile devices. Based on this key, group users establish a confidential communication channel between their devices. NFV achieves group devices pairing without the complex operations needed in prior works. We implemented NFV using off-theshelf Android smartphones. The experimental results shows the efficiency and security of our system.
Highly electronegative low‐density lipoprotein L5 evokes microglial activation and creates a neuroinflammatory stress via Toll‐like receptor 4 signaling

Atherogenic risk factors, such as hypercholesterolemia, are associated with increased risk of neurodegeneration, especially Alzheimer's dementia. Human plasma electronegative low‐density lipoprotein [LDL(−)], especially L5, may serve as an important contributing factor. L5 promoting an inflammatory action in atherosclerosis has been extensively studied. However, the role of L5 in inducing neuroinflammation remains unknown. Here, we examined the impact of L5 on immune activation and cell viability in cultured BV‐2 microglia. BV‐2 cells treated with lipopolysaccharide or human LDLs (L1, L5, or oxLDL) were subjected to molecular/biochemical assays for measuring microglial activation, levels of inflammatory factors, and cell survival. A transwell BV‐2/N2a co‐culture was used to assess N2a cell viability following BV‐2 cell exposure to L5. We found that L5 enables the activation of microglia and elicits an inflammatory response, as evidenced by increased oxygen/nitrogen free radicals (nitric oxide, reactive oxygen species, and peroxides), elevated tumor necrosis factor‐α levels, decreased basal interleukin‐10 levels, and augmented production of pro‐inflammatory proteins (inducible nitric oxide synthase and cyclooxygenase‐2). L5 also triggered BV‐2 cell death primarily via apoptosis. These effects were markedly disrupted by the application of signaling pathway inhibitors, thus demonstrating that L5 interacts with Toll‐like receptor 4 to modulate multiple pathways, including MAPKs, PI3K/Akt, and NF‐κB. Decreased N2a cell viability in a transwell co‐culture was mainly ascribed to L5‐induced BV‐2 cell activation. Together, our data suggest that L5 creates a neuroinflammatory stress via microglial Toll‐like receptor 4, thereby leading to the death of BV‐2 microglia and coexistent N2a cells. Atherogenic L5 possibly contributes to neuroinflammation‐related neurodegeneration.
Structural recognition of tabulated data

A system for extraction of structural information of a table from its image is discussed. Following the initial binarization and deskewing operations, the image is scanned to extract all horizontal and vertical lines that are present. The table's dimensions are estimated based on these lines. Unlike other systems, the procedure described does not depend on the sole existence of lines to mark the item blocks. White streams are recognized in both the horizontal and vertical direction as substitutes for any missing demarcation lines. A structure interpretation procedure uses the extracted demarcation information to identify each of the item blocks in the table. Subsequently, the interrelations of these item blocks are used to recognize the structure of the tabulated data. <<ETX>>
Optimal power allocation of pilot symbols for LS channel estimation in OFDMA uplink

In the uplink transmission of Orthogonal Frequency Division Multiple Access (OFDMA) systems, the subcarriers are assigned to uplink users by the system scheduler. Since each user only applies a portion of the subcarriers and the users experience different multipath channels, conventional channel estimation approach using uniformly placed pilot tones and uniform power allocation is not applicable. In this paper, we assume the places of the pilot tones have been decided by the scheduler and consider optimal power allocation of the pilot symbols, so as to minimize the mean square error (MSE) of channel estimation. The problem is formulated as a classical semidefinite programming (SDP) problem, and hence it can be solved with polynomial complexity.
A comparative electrophysiological study of motor end‐plate diseased skeletal muscle in the mouse.

1. Experiments using intracellular recording, stimulation, and microionophoretic techniques were performed on extensor digitorum longus nerve‐muscle preparations excised from mice having hereditary ‘motor end‐plate disease'. Control experiments were performed on normal innervated and chronically denervated nerve‐muscle preparations. 2. Two physiologically distinct groups of muscle fibres were found in the diseased muscles. Group I is similar to normal innervated muscle with respect to resting potentials, cable properties, neuromuscular transmission, miniature end‐plate potentials, and extrajunctional acetylcholine sensitivity. Group II is similar to denervated muscle in the above respects except that (i) neuromuscular transmission, though abnormal, was present, and (ii) miniature end‐plate potentials (m.e.p.p.s), often having large amplitudes, were found in these muscle fibres. 3. Large m.e. p.p.s appear to be due to an increase in muscle fibre input resistance and to the quantal release of abnormally large amounts of acetylcholine from motor nerve terminals. 4. Nerve stimulation of group II muscle fibres evoked action potentials with a delayed repolarization phase, suggesting that a prolonged acetylcholine‐induced conductance change occurs at motor end‐plates. 5. Neuromuscular physiology in motor end‐plate disease is similar to that reported for frog nerve‐muscle preparations which have been incubated in high Ca2+ Ringer.
Improvement of Person Tracking Accuracy in Camera Network by Fusing WiFi and Visual Information

Person tracking in camera network is still an open subject nowadays. The main challenge for this problem is how to link exactly individual trajectories when people move in a camera FOV (Field of View) or switch to other ones. This refers to solve the problem of person re-identication (Re-ID) in tracking process. A popular method for this is assigning the current position with the previous one based on the minimum distance between them. This is called as person identication by tracking. In this work, we approach tracking by identication, which means the trajectory assignment is done by the person identity (ID) determined at each video frame. In order to improve the accuracy of vision-based person tracking, we focus on accuracy enhancement for person identication by adding ID of the WiFi-enable device held by each person. A fusion scheme of WiFi and visual signals is proposed in this work for person tracking. An optimal assignment and Kalman lter are used in this combination to assign the position observations and predicted states from camera and WiFi systems. The correction step of Kalman lter is then applied for each tracker to give out state estimations of locations. The fusion method allows tracking by identication in non-overlapping cameras, with clear iden tity information taken from WiFi adapter. The experiments on a multi-model dataset show outperforming tracking results of the proposed fusion method in comparison with vision-based only method.
Seasonal variations of metal concentrations in periphyton and taxonomic composition of the algal community at a Yenisei River littoral site

The concentrations of metals K, Na, Ca, Mg, Fe, Mn, Zn, Cu, Ni, Pb, Co and Cr, in the water and periphyton (epilithic algal communities) were studied at a site in the middle stream of the Yenisei River (Siberia, Russia) during three years using monthly sampling frequencies. Despite considerable seasonal variations in aquatic concentrations of some metals, there was no correlation between metal contents in the water and in periphyton. Seasonal concentration variations of some metals in periphyton were related to the species (taxonomic) composition of periphytic microalgae and cyanobacteria. Enhanced levels of Ni and Co in periphyton in late autumn, winter, and early spring were likely caused by the predominance of cyanobacteria in the periphytic community, and annual maximum levels of K in periphyton in late spring and early summer were attributed to the domination of Chlorophyta, primarily Ulothrix zonata.
Development of a linear position independent Inductive Energy Transfer system

An inductively coupled contactless energy transfer system for translating motion that is able to transfer 1 kW of power is proposed in this paper. The system consists of a gapped transformer with multiple secondary coils and a single primary one. Using this approach a long stroke energy transfer system can be constructed. No active control for switching on the moving side of the transformer is required. The magnetic design of the transformer is such, that the position dependency of the transformer parameters is minimized. This allows a fixed capacitor value to be used to operate the system close to resonant mode. The magnetic design procedure of the core is described and analyzed. The design has been implemented and measurements on the prototype have been conducted.
Monoclonal antibody therapy for resected Dukes' C colorectal cancer: seven-year outcome of a multicenter randomized trial.

PURPOSE As previously shown, antibody treatment increased survival of patients with resected colorectal cancer of stage Dukes' C. Since the 5-year analysis was criticized because of the wide range (2.7 to 7.5 years) of follow-up time, we performed a 7-year analysis with only four of 189 patients monitored for less than 5 years. PATIENTS AND METHODS A total of 189 patients with resected Dukes' C colorectal cancer were randomly allocated to infusions of a total of 900 mg 17-1A antibody, 500 mg postoperatively followed by 4 monthly doses of 100 mg (n=99), or to observation only (n=90). Primary end points were overall survival and disease-free interval. Patients were stratified by a dynamic randomization according to center, sex, location of tumor, number of affected lymph nodes, and preoperative carcinoembryonic antigen concentration. RESULTS Randomization produced balanced distribution of risk factors. After 7 years of follow-up evaluation, treatment had reduced overall mortality by 32% (Cox's proportional hazard, P < .01; log-rank, P=.01) and decreased the recurrence rate by 23% (Cox's proportional hazard, P < .04; log-rank, P=.07). The intention-to-treat analysis gave a significant effect for overall survival (Cox's proportional hazard, P < .01; log-rank, P=.02) and disease-free survival (Cox's proportional hazard, P=.02; log-rank, P=.11 ). While distant metastases were significantly reduced (Cox's proportional hazard, P=.004; log-rank, P=.004), local relapses were not (Cox's proportional hazard, P=.65; log-rank, P=.52). This differential effect of 17-1A antibody on disseminated isolated tumor cells versus occult local satellites may explain the increased significance seen in the overall survival. CONCLUSION The now-matured study shows that 17-1A antibody administered after surgery prevents the development of distant metastasis in approximately one third of patients. The therapeutic effect is maintained after 7 years of follow-up evaluation.
