In this paper, we propose to build an Online Pesticide Information Center and Discovery Platform to solve these problems, such as the disunity of the retrieval and identification of chemical information database and the different emphases of the information covered by each other. Through the design of the system workflow and system modules, the crawler method is selected and improved according to the actual situation. And combined with the intelligent matching of pesticide information, the Online Pesticide Information Center and Discovery Platform is designed and implemented. The platform unifies the standard of retrieval entrance, integrates all kinds of pesticide information needed by researchers, and provides powerful decision support for researchers helping them with the rational design of pesticides.

The traditional NH3 production method (Haber-Bosch process) is currently complemented by electrochemical synthesis at ambient conditions, but the rather low selectivity (as indicated by the Faradaic efficiency) for the electrochemical reduction of molecular N2 into NH3 impedes the progress. Here, we present a powerful method to significantly boost the Faradaic efficiency of Au electrocatalysts to 67.8% for the nitrogen reduction reaction (NRR) by increasing their electron density through the construction of inorganic donor-acceptor couples of Ni and Au nanoparticles. The unique role of the electron-rich Au centers in facilitating the fixation and activation of N2 was also investigated via theoretical simulation methods and then confirmed by experimental results. The highly coupled Au and Ni nanoparticles supported on nitrogen-doped carbon are stable for reuse and long-term performance of the NRR, making the electrochemical process more sustainable for practical application.

Engineering the adsorption of molecules on active sites is an integral and challenging part for the design of highly efficient transition-metal-based catalysts for methanol dehydrogenation. A Mott-Schottky catalyst composed of Ni nanoparticles and tailorable nitrogen-doped carbon-foam (Ni/NCF) and thus tunable adsorption energy is presented for highly efficient and selective dehydrogenation of gas-phase methanol to hydrogen and CO even under relatively high weight hourly space velocities (WHSV). Both theoretical and experimental results reveal the key role of the rectifying contact at the Ni/NCF boundaries in tailoring the electron density of Ni species and enhancing the absorption energies of methanol molecules, which leads to a remarkably high turnover frequency (TOF) value (356 mol methanol mol-1 Ni h-1 at 350 °C), outpacing previously reported bench-marked transition-metal catalysts 10-fold.

Multi-sensor information fusion refers to the handling for the uniform form of expression obtained by calibration, alliance, correlation and merging towards the data from multiple sensors. Compared with a single sensor, for the solution of the target states or the judgment of target characteristics, multi-sensor information fusion technology can enhance the reliability of the data, improve the accuracy and increase instantaneity of the systems and information utilization, etc. Multi-sensor data can supplement each other, but it may also have lower confidence coefficient and become redundancy. Therefore, the adjustment process for the measured data by the means of fusion algorithm is a key to obtain the accurate data. Based on the algorithm of chaotic thoughts, an algorithm which fused the data of temperature and humidity at a boar station was put forward to carry out an experiment in this paper. The experiment proved that this algorithm was effective to extract the useful information from different fusion data and it obtained a good fusion effect.

Introduction: The burden of MDR-TB leads to increment in healthcare cost and long treatment duration. Studying the disease characteristics and treatment outcome would assist the clinician in managing it. Objectives: To determine the MDR-TB treatment outcome in our centre and treatment side effects. We hypothesize that certain clinical characteristics are associated with poorer treatment outcome. Methods: A retrospective study was conducted to review the medical records of all MDR-TB patients registered in Institute of Respiratory Medicine, Kuala Lumpur from 2015-2016. Demographic data, disease characteristics, treatment outcome and adverse drug reactions were recorded and analyzed. Results: 63 patients were diagnosed to have MDR-TB, comprised of 42 males and 21 females, with mean age of 39.6±12.6 year. Primary and acquired MDR-TB were 33.3% and 66.7% respectively. Majority of the cases were pulmonary tuberculosis (88.9%) and 63.5% were smear positive. 71.4% were treated with conventional MDR-TB regimen; mean treatment duration are 13±8.1 months. MDR-TB treatment success rate in our centre was 49.2%(31/63). 41.3% of MDR-TB patients have poor outcome, including 20 treatment defaults, 2 relapse MDR-TB and 4 mortalities. 6 patients were transferred to other centres. Male gender(p=0.006) and smoker(p=0.018) were associated with poor treatment outcome. 66.7% patients developed adverse drug reactions such as vomiting (15.8%), hypothyroidism (15.8%), psychotic symptoms (14%) and ototoxicity (10.5%). Conclusions: About half of the MDR-TB cases in our centre achieved successful treatment outcome. Poor treatment outcome was seen in male and smoker.

For fiscal year 2017, according to the Department of Energy’s June 2018 sustainability performance report, the DoD’s total energy consumption stood at 210 quadrillion joules (199 trillion Btu) of energy with a total energy expenditure of $11.9 billion. The majority of its energy budget was spent on the purchase of fossil fuels. This reliance on fossil fuels to sustain military operations would pose serious financial, operational, and strategic challenges and risks to the energy security and resiliency of the military. To reduce the reliance on fossil fuels, SECNAV has set forth five energy goals as key steps for the Navy to switch to alternative renewable energy sources. This thesis focuses on the design and development of a feasible micro-grid powered by renewable energy to fulfil SECNAV’s energy goal of increasing alternative energy ashore by producing 50% of shore-based energy requirements from alternative sources by 2020. The main aim of the thesis is to design and provide a proof of concept for an automated industrial control of a supercapacitor microgrid and compressed air storage system by integrating an alternate power supply in the supercapacitor solar microgrid and compressed air storage system, and by designing an algorithm to control the power supply using off-the-shelf automated industrial components. http://archive.org/details/industrialcontro1094562305 Outstanding Thesis Major, Republic of Singapore Navy Approved for public release; distribution is unlimited.

There is a lack of non-invasive screening modalities to diagnose chronic atrophic gastritis (CAG) and intestinal metaplasia (IM). Thus, the aim of the present study was to determine the sensitivity and specificity of serum pepsinogen I (PGI), PGI:II, the PGI:II ratio and gastrin-17 (G-17) in diagnosing CAG and IM, and the correlations between these serum biomarkers and pre-malignant gastric lesions. A cross-sectional study of 72 patients (82% of the calculated sample size) who underwent oesophageal-gastro-duodenoscopy for dyspepsia was performed in the present study. The mean age of the participants was 56.2±16.2 years. Serum PGI:I, PGI:II, G-17 and Helicobacter pylori antibody levels were measured by enzyme-linked immunosorbent assay. Median levels of PGI:I, PGI:II, the PGI:II ratio and G-17 for were 129.9 µg/l, 10.3 µg/l, 14.7 and 4.4 pmol/l, respectively. Subjects with corpus CAG/IM exhibited a significantly lower PGI:II ratio (7.2) compared with the control group (15.7; P

Proteomic studies are highly dependent on instrumentation. In this project, aspects of electrophoresis, densitometry and microplate technology have been developed. In the work on densitometry, the first notion was to develop a refined laser densitometer system. In view of the prohibitive cost of such a system, adapted flatbed scanners were developed instead to quantify electrophoresis gels with the aid of accurate optical density calibration using step wedges. Various aspects of illumination using light emitting diode and liquid crystal display backlighting were also investigated. In advancing the microplate technology, the use of microplate wells to function like capillaries for filling of samples in high throughput screening without precise instrumentation was introduced. The principle of light shielding and total internal reflection by light emitting diodes was also implemented for non imaging quantification of protein samples without optical filters. With the imaging quantification approach, the problematic effects of point spread function and liquid meniscus of small liquid volumes on standard microplates were shown. In that vein, the capability of our capillary wells microplate design to overcome this limitation was demonstrated. In another aspect of imaging quantification, an innovative capillary wells microplate approach that permitted side viewing, as compared to standard microplates which only allows top viewing, was implemented. With this approach, errors arising from bubbles during measurement could be revealed and pipetting errors detected during actual assay runs. In the effort related to electrophoresis, we developed a coverslip fluidic approach that potentially could be used for simple and cost effective capillary electrophoresis. Currently, this is done using capillary tubes which makes quantification possible only with specialized instrumentation.

Conventional method to define the useful tool life is by punching the actual molded units in trim and form (TNF) machine. Throughout the punch intervals, the punched leadframes were sent for inspection for any side burr observed at the leads. This process might take several days or weeks in order to reach the end of punch tool lifespan. It is quite a manual and time consuming task, if it involves several types of punch tool to be examined. Beside that, this method does not capture the wear rate of the punch tool. This paper demonstrates the friction wear test of punch tool to obtain the wear rate using Bruker Tribolab UMT tester, which is equipped with reciprocating drive. The punch tool is hold stationary at the carriage (z axis), and rub against the dummy molded unit, which oscillated by the reciprocating drive. The volume loss of the punch tool is plotted against the number of reciprocating cycles to determine the wear rate. The wear mode of the punch tool is investigated at end of the test. From the results of this study, it is shown that the punch tool's volume wear vs the reciprocating cycles fit well with the linear line. The wear rate of punch tool is calculated from the slope of the linear line.

As per the requirements of the market, current semiconductor trend is towards shrinking packages thereby reducing package dimensions. This in turn results in reduced lead pitch and width giving less space for contacting during final testing. Another trend recently observed for the package lead is the shift from matteSn plating towards preplated leadframes or otherwise called uPPF. When it comes to power testing requirements like kelvin testing that needs to have two contacts on single lead this shift is a challenge for contacting. This paper discusses in detail the observations of the difference in the material interaction between pin and the two different leadframes at constant current flowing through the pin.

With the further development of the electromagnetic exploration technologies, the forward and inversion modeling of geophysical in three-dimensional numerical simulation fields is confronted with huge challenges. During the process of solving the partial differential equations, the methods of finite difference, finite element and volume element methods are usually adopted. For the complex topographic condition and geological structure, the conditions of the matrix formed finally will be very poor, seriously affecting the iterative and convergence rate in equation solution. In this paper, the algebraic multigrid preconditioned methods and conjugate gradient solution process are adopted to conduct parallel processing in combination of graphics processing unit (GPU), and the efficiency of DCs threedimensional forward modeling will be effectively improved.

In this paper, by comparing the basic equations and variational problem of two-dimensional magneto telluric (2DMT) method for symmetric anisotropic with isotropic bodies show the difference between the two cases in TE (Transverse Electric) and TM (Transverse Magnetic) modes. This paper adopts rectangular element subdivision and bilinear interpolation. The comparison results show that in TM mode the measuring point above the abnormal body can more effectively reflect the anisotropy effect than the one which is far away from the abnormal body. In addition, the results demonstrate that in TM mode the anisotropy effect cannot be ignored, and then in TE mode it is not sensitive to the anisotropy.

A total of 90 precipitation samples were collected from individual precipitation events at the Qilian Alpine EcologyHydrology Research Station (Hulugou Station, 30 degrees 47'N, 90 degrees 58'E; 3 260 m a. s. l) located in the central Qilian Mountains from August 2012 to November 2013. All samples were analyzed for major cations (Na, K+, Ca2+ and Mg2+), anions (Cl- , NO3- and SO4(2-)) and conductivity. Precipitation EC values ranged from 2.26 to 482 μS x cm(-1) with an average value of 41.9 μS x cm(-1). The precipitation was of SO4(2-) -Mg(2+) -Ca2+ type, which contributed70% to the total ionic concentration. The same as the precipitation alkalinity, precipitation events occurred around summer showed lower concentrations, while it had higher concentrations in winter and spring with little precipitation and larger wind speed. Enrichment factor (EF), correlation and factor analysis indicated that regional crustal aerosols and species from central Asian and northwestern China arid regions brought by the westerly circulation were the major sources for these ions, some dust from human pollution were the secondary sources, and the contribution of sea salt was the least due to the long distance transport. These characteristics could be also confirmed by the correlation between ionic concentrations and metrological data in the study region. It is also interesting that the precipitation chemistry was different under the different atmospheric circulation: the monsoon precipitation, the interaction precipitation events ( influenced both by monsoon and westerly) and the westerly precipitation.

The workload of the 3D magnetotelluric forward modeling algorithm is so large that the traditional serial algorithm costs an extremely large compute time. However, the 3D forward modeling algorithm can process the data in the frequency domain, which is very suitable for parallel computation. With the advantage of MPI and based on an analysis of the flow of the 3D magnetotelluric serial forward algorithm, we suggest the idea of parallel computation and apply it. Three theoretical models are tested and the execution efficiency is compared in different situations. The results indicate that the parallel 3D forward modeling computation is correct and the efficiency is greatly improved. This method is suitable for large size geophysical computations.

Based on the characteristics of make-to-order manufacturing, risks in enterprises are analyzed, which are encountered when receiving orders. Dividing the whole process into three stages, this paper provides a qualitative explanation of the risky factors, failure rate, risk level and changes of each stage, and then provides a mathematic model of quantitative analysis by using fuzzy sets and an analytical hierarchy process. In the light of the relationship among the three stages, a formula for calculating risk levels of orders is worked out. Meanwhile, both economic and non-economic losses due to an order failure are considered in the assessment system. An actual case is analyzed using the described method. Suggestions for risk prevention or loss reduction are given.

Evapotranspiration (ET) is an important component of water cycle, but its measurement in high altitude mountainous region is quite difficult, inducing the insufficient understanding on the actual ET in high altitude mountainous region and the effects of ET on this region' s water cycle. In this paper, two small type weighing mini-lysimeters were applied to measure the daily ET in a piece of grassland in a high altitude mountainous region of the Heihe River basin from July 1st, 2009 to June 30th, 2010. Based on the measured data, the methods of FAO-56 Penman-Monteith (F-P-M), Priestley-Taylor (P-T), and Hargreaves-Samani (H-S) were employed to estimate the ET to analyze the applicability of the three methods for the mountainous region, and the pan coefficient at the measurement spots was discussed. During the measurement period, the total annual ET at the measurement spots was 439.9 mm, accounting for 96.5% of the precipitation in the same period, and the ET showed an obvious seasonal distribution, being 389. 3 mm in May-October, accounting for 88. 5% of the annual value. All the three methods could be well applied to estimate the summer ET but not the winter ET, and their applicability followed the sequence of P-TF-P-MH-S. At the measurement spots, the daily pan coefficient in summer was 0.7-0. 8, while that in winter was quite variable.

In the recent period, the actual electrical prospecting process, three-dimensional forward problem has been the key to the earth exploration research. Generally speaking, people use the finite element method and finite difference method for solving three-dimensional power forward to the results of the electric field, and they would get a large sparse linear equation. In the process of solving equations, the time complexity of serial computing is relatively high, and the computational efficiency is very low, unable to meet the application requirements. With the parallel computer architecture matures, the vector equation for parallel computing operations is suited in the process of the pre-condition factor and the reconciliation. In this paper, we use GPGPU parallel computing model, significantly improving the efficiency of the three-dimensional magnetotelluric forward.

This PATH Research Report covers the (Vehicle-Infrastructure Integration) VII California Development and Deployment (Task Order 5217) efforts from October 2005 – December 2007. Because TO 5217 is followed by the continuation TO 6127, it is a compendium of very applications-oriented research to date as well as a final report to TO 5217.It is organized to impart the very specific and generally very pragmatic implementation details first, beginning with an introduction (Section 1), description of VII hardware, general network and installation (Section 2), then progressing to a more detailed description of the network and operating software (Section 3) and finally to applications in development and prospective applications (Section 4). Because it is not yet a final report but rather a ‘research in progress’ report, it does not comprehensively address every task in the VII California family of task orders; specifically, several of the applications described in Section 4 are represented as works in progress (as they are at this writing), and the on-ramp metering study is not yet reported. Again, the purpose, of this report is to provide the reader with an understanding of how VII California was implemented.

A number of parameters related to Agrobacterium-mediated infection were tested to optimize transformation frequencies of sorghum (Sorghum bicolor L.). A plasmid with a selectable marker, phosphomannose isomerase, and an sgfp reporter gene was used. First, storing immature spikes at 4A degrees C before use decreased frequency of GFP-expressing calli, for example, in sorghum variety P898012 from 22.5% at 0 day to 6.4% at 5 days. Next, heating immature embryos (IEs) at various temperatures for 3 min prior to Agrobacterium infection increased frequencies of GFP-expressing calli, of mannose-selected calli and of transformed calli. The optimal 43A degrees C heat treatment increased transformation frequencies from 2.6% with no heat to 7.6%. Using different heating times at 43A degrees C prior to infection showed 3 min was optimal. Centrifuging IEs with no heat or heating at various temperatures decreased frequencies of all tissue responses; however, both heat and centrifugation increased de-differentiation of tissue. If IEs were cooled at 25A degrees C versus on ice after heating and prior to infection, numbers with GFP-expressing cells increased from 34.2 to 49.1%. The most optimal treatment, 43A degrees C for 3 min, cooling at 25A degrees C and no centrifugation, yielded 49.1% GFP-expressing calli and 8.3% stable transformation frequency. Transformation frequencies greater than 7% were routinely observed using similar treatments over 5 months of testing. This reproducible frequency, calculated as numbers of independent IEs producing regenerable transgenic tissues, confirmed by PCR, western and DNA hybridization analysis, divided by total numbers of IEs infected, is several-fold higher than published frequencies.

A circuit structure which performs perfect memory association for the case where the stored memory patterns are any set of orthogonal vectors in an n -dimensional space is proposed. This circuit is based on a new interpretation of the classical flip-flop which is the basis of the majority of current circuit implementations of artificial neural networks. The result shows that for the simplified memory association problem considered, which so far has not been satisfactorily solved, a natural generalization of the flip-flop to higher dimensions provides a simple and elegant solution

Keywords longitudinal control, car platooning, back-stepping control, multi-surface dynamic sliding mode control, integral filters, realtime control code This report presents the development of nonlinear longitudinal controllers and their realtime implementation for Automated Highway Systems (AHS) at PATH, U. C. Berkeley supported by the project MOU 331. The demo'97 realtime code was first reconstructed for further development. Based on the new framework, the implementation and comparison of nonlinear controllers in the longitudinal control for cars platooning and other maneuvers have been carried out. Specifically, a dynamic sliding mode controller and a dynamic back-stepping multiple surface controller have been implemented, which are then compared to the previously implemented adaptive sliding mode controller. In the dynamic back-stepping control, a new type of integral filters have been developed, which were used for filtering measured signals and to estimate the derivative of these signals in realtime. These controllers have been implemented in realtime code and tested at low and high speed. Realtime run shows that each controller has its own characteristics. In general, the optimal dynamic back-stepping sliding surface controller has better performance by using the same set of measured data compared to previously implemented adaptive sliding mode controller. Emphasis has been put on the dynamic back-stepping multiple surface controller development.

Healing of the inner wall of the same preclotted knitted Dacron arterial prostheses was compared in the descending thoracic aorta (DTA) and the abdominal aorta (AA) of the same dog. Each of 16 dogs received this dual implantation with study periods of 4 weeks for five dogs, 8 weeks for five dogs, and 16 weeks for six dogs. Healing was studied with light microscopy, scanning electron microscopy, transmission electron microscopy, and immunocytochemistry identification. The outer capsule was firmly adherent to the Dacron framework of all grafts implanted in the DTA; advanced healing of the inner wall of all thoracic grafts was present by 4 weeks, nearly complete healing by 8 weeks, and complete healing by 16 weeks. In contrast, the outer capsule was either not attached or only loosely adherent to the Dacron framework in eight AA grafts (50%), and in these implants no healing of the inner wall occurred beyond the limited perianastomotic pannus zone. In the other eight implants in which the outer capsule was firmly adherent to the Dacron framework, healing was roughly comparable to that in the grafts implanted in the DTA. This study demonstrated that (1) DTA grafts heal faster and more completely than AA grafts, (2) healing and endothelialization are related to the tightness of the outer capsule, (3) there is a high incidence of loose tissue attachment in the AA, and (4) healing of aortic grafts is site specific.
