Study of the Circular Flat Spiral Coil Structure Effect on Wireless Power Transfer System Performance (2018)

This paper analyses the relationship between the coil design parameters and the system performance, including power transfer efficiency and amount, when circular flat spiral coils are adopted in a wireless power transfer (WPT) system. Coil design variables including outer radius, inner radius, channel width and coil turns are thoroughly studied to improve the system performance with a limited maximum outer radius for practical purposes. A two-coil WPT system has been built to verify the analysis, and the experimental results show good consistency with the theoretical calculations and simulation results, which show that the coil design parameters have a significant impact on the system performance, even with the same coil size. In the experiments, the coil-to-coil distance is 150 mm, the maximum coil outer radius is limited in 300 mm, and the DC input voltage and the load resistance are 100 V and 5 Ω, respectively. When the coils are tightly-wound in the most traditional way to maximize the coil size, the coil-system efficiency is 62.6% with only 4.5 W load power. In contrast, the efficiency optimized coil can improve the coil-system efficiency to 91.2% with the outer radius stayed the same. Besides, when the power transfer efficiency and amount are considered simultaneously, the system can achieve 1279 W load power with 85.94% coil-system efficiency.
Dflow workflow management system (2002)

Process specification, automatic recovery, concurrency control and heterogeneity among processing entities are known problems of workflow management systems. Dflow provides a workflow specification language which combines the expressive power of a structural programming language with the recovery capabilities of transaction systems. Dflow tries to solve the problems of automatic recovery in its model and the problems of concurrency control and heterogeneity in its architecture.
Lessons from Controversy: Ovarian Cancer Screening and Serum Proteomics (2005)

In 2002 a study reported that a blood test, based on pattern-recognition proteomics mass spectroscopy analysis of serum, was nearly 100% sensitive and specific to detect ovarian cancer. Plans to introduce a commercial screening test by early 2004 were delayed amid concerns about whether the approach was reproducible and reliable. In this issue of JNCI, two commentaries discuss whether the initial results are reproducible and whether bias may account for results. This essay describes how threats to validity from chance and bias may cause erroneous results and inflated expectations in the kind of observational research being conducted in several "-omics" fields to assess molecular markers for diagnosis and prognosis of cancer. To address such threats and to realize the potential of new -omics technology will require application of appropriate rules of evidence in the design, conduct, and interpretation of clinical research about molecular markers.
IgA antibodies in the bile of rats. II. Evidence for immunological memory in secretory immunity. (1982)

The Peyer's patches of Wistar rats were injected with suspensions of either sheep red blood cells (SRBC) or killed Brucella abortus organisms in doses that were insufficient to induce the appearance of biliary antibodies. The rats were challenged after periods ranging from 1 week to 1 year with the same dose of antigen given by the same route, and their bile was monitored for the appearance of specific antibodies. The test animals produced biliary antibodies to a much higher titre, and usually more rapidly, than control rats which had received the total dose of antigen as a single injection. As in primary responses, the biliary antibodies produced by challenging the primed rats were predominantly from the IgA class. The ability to mount substantial biliary responses to suboptimal doses of antigen could be transferred from primed donor rats to unimmunized recipients by thoracic duct lymphocytes, but not humoral factors, collected between 3 weeks and 5 months after priming. Gamma-irradiation of the lymphocytes abolished this effect. These results suggest strongly that immunological memory exists in the IgA system and that it is mediated by circulating lymphocytes.
High efficiency, Site-specific Transfection of Adherent Cells with siRNA Using Microelectrode Arrays (MEA) (2012)

The discovery of RNAi pathway in eukaryotes and the subsequent development of RNAi agents, such as siRNA and shRNA, have achieved a potent method for silencing specific genes for functional genomics and therapeutics. A major challenge involved in RNAi based studies is the delivery of RNAi agents to targeted cells. Traditional non-viral delivery techniques, such as bulk electroporation and chemical transfection methods often lack the necessary spatial control over delivery and afford poor transfection efficiencies. Recent advances in chemical transfection methods such as cationic lipids, cationic polymers and nanoparticles have resulted in highly enhanced transfection efficiencies. However, these techniques still fail to offer precise spatial control over delivery that can immensely benefit miniaturized high-throughput technologies, single cell studies and investigation of cell-cell interactions. Recent technological advances in gene delivery have enabled high-throughput transfection of adherent cells, a majority of which use microscale electroporation. Microscale electroporation offers precise spatio-temporal control over delivery (up to single cells) and has been shown to achieve high efficiencies. Additionally, electroporation based approaches do not require a prolonged period of incubation (typically 4 hours) with siRNA and DNA complexes as necessary in chemical based transfection methods and lead to direct entry of naked siRNA and DNA molecules into the cell cytoplasm. As a consequence gene expression can be achieved as early as six hours after transfection. Our lab has previously demonstrated the use of microelectrode arrays (MEA) for site-specific transfection in adherent mammalian cell cultures. In the MEA based approach, delivery of genetic payload is achieved via localized micro-scale electroporation of cells. An application of electric pulse to selected electrodes generates local electric field that leads to electroporation of cells present in the region of the stimulated electrodes. The independent control of the micro-electrodes provides spatial and temporal control over transfection and also enables multiple transfection based experiments to be performed on the same culture increasing the experimental throughput and reducing culture-to-culture variability. Here we describe the experimental setup and the protocol for targeted transfection of adherent HeLa cells with a fluorescently tagged scrambled sequence siRNA using electroporation. The same protocol can also be used for transfection of plasmid vectors. Additionally, the protocol described here can be easily extended to a variety of mammalian cell lines with minor modifications. Commercial availability of MEAs with both pre-defined and custom electrode patterns make this technique accessible to most research labs with basic cell culture equipment.
Reactive task execution of a mobile robot (1998)

This thesis presents a novel control architecture, Samba, for reactive task execution. Reactive task execution implies goal-oriented and reactive properties from a robot and the ability to execute several tasks at the same time, also in a dynamic environment. These requirements are fulfilled in Samba by the representations of goals, intermediate results, and robot actions. The key idea in Samba is to produce continuously reactions for all the important objects in the environment. These reactions are represented as action maps, which are a novel representation for robot actions. An action map specifies for each possible action how preferable the action is from the perspective of the producer of the map. The preferences are shown by assigning a weight to each action. Tasks are executed by modifying and combining action maps. The tasks can be either reasoned by a higher layer or triggered by sensor data. Action maps, and the methods for modifying and combining them, enable executing tasks in parallel and considering the dynamics of the environment. Further, as the action maps are produced continuously from sensor data, the robot actions are based on the current state of the environment. Markers describe goals and intermediate results. They facilitate managing the complexity of the system. Markers describing intermediate results decompose the system vertically, into producers and consumers of data. Markers describing goals decompose the control system horizontally, into a Samba layer and a higher layer of reasoning tasks. Tasks flow via markers from the higher layer to the Samba layer. Markers are tested on a real robot equipped with a stereo gaze platform. Further, the Samba architecture is applied to playing soccer. Experiments were carried out in the 1997 and 1998 RoboCup competitions. These experiments show that the Samba architecture is a potential alternative for controlling a mobile robot in a dynamic environment.

A new method of measuring propagation coefficients and characteristic impedance in blood vessels. (1975)

True propagation coefficients of pulse wave harmonics in an artery can be determined in vivo by measuring pulsatile blood pressure and flow at each of two points along the length of the vessel. These coefficients, which are complex numbers that describe the attenuation and the phase shift imposed on a traveling wave, are independent of the reflected waves in the circulation and thus provide information about the viscoelastic state and other properties of an artery. The equations involved are implicit in standard transmission-line theory, but they have not previously been applied in this particular way to blood vessels. The femoral artery, exposed in situ, was studied in 11 anesthetized dogs. At 1.5 Hz, true attenuation constants averaged 0.0151 nepers/cm, and true phase constants averaged 0.0155 radians/cm. As frequency increased, the apparent phase velocity of flow, in contrast, was relatively low at the first harmonic and rose as frequency increased. True phase velocities lay between the apparent pressure and flow values. Characteristic impedance at 1.5 Hz had an average modulus of 1.76 times 10-4 dyne sec/cm5 and a phase of minus 0.31 radians. The modulus diminished as frequency increased, and the phase became less negative. These results show that true phase constants and characteristic impedances determined by this method are consistent with data reported by others and provide information not previously available about flow wave propagation.
A Study on an Agent Based Approach to Monitor the Application Feature Usage (2014)

Usability has gained a paramount significance in the recent trends of software application development. Application usage (AU) means the data, which consists of history of user interactions of an application. Knowledge of usage patterns in the AU is required for developing an application with rich features and that appeal to majority of users, with good usability. Monitoring the user interactions of an application for AU data is becoming a premier in recent days and this feature of aggregating the AU data is being added to good number of applications yet to be commissioned. But it is a major challenge to add this feature to the commissioned applications which are running successfully. It is also difficult to support the new applications with zero impact on the software engineering process. Legacy solutions for aggregating AU data are using the concepts of Aspect Oriented Programming (AOP) and Attribute programming. These approaches provide the high coupling between the modules/applications, which increases the dependency of one module/application on the other. These approaches impact the Non-functional requirements (NFR's) of an application. In case of products already released and running successfully at the customer deployments, it's almost impossible to go with legacy solutions. This paper addresses a technique to accumulate the AU data of an application, which can be used to find the usage patterns. This knowledge of usage patterns in AU data, there by helps in increasing the usability, achieving maintainability, retaining performance and offers flexibility to an application.
INFLUENCE OF PRECIPITATION AND SUGARCANE STRAW IN AMINOCYCLOPYRACHLOR AND INDAZIFLAM CONTROL EFFICIENCY (2015)

ABSTRACTThe raw sugarcane harvesting system has changed the dynamics of weed tillage for this crop, changing the predominant weed species and providing a barrier between the herbicide and the soil. Thus, this study has aimed to assess the influence of precipitation and sugarcane straw in the aminocyclopyrachlor and indaziflam herbicides control efficiency for the species Ipomoea trilobaand Euphorbia heterophylla. There were two trials, one for aminocyclopyrachlor and one for the indaziflam, both in the greenhouse at the campus of Faculdade Integrado in the Brazilian city of Campo Mourão, PR. Each experiment consisted of eight treatments with four replications. The treatments consisted of the combination of the presence of straw (10 t ha-1), capillary irrigation and rainfall simulation (20 mm). Assessments of control percentage of I.triloba and E.heterophylla were carried out, as well as the number of plants per pot. The aminocyclopyrachlor and indaziflam herbicides applied directly to the soil were efficient in controlling these species. The 20 mm rainfall simulation or daily irrigation on the straw are indispensable to promote the removal of aminocyclopyrachlor and indaziflam from the straw and provide satisfactory control of I.triloba and E.heterophylla.
Product Liability and the Pill (1970)

The Pill has been on the market now for ten years and has been inwide use for five. Only within the last year, however, have widespread reports of the adverse effects associated with the Pill been publicized. While the Pill manufacturers may be aiding society by providing a convenient and effective method of checking the overpopulation problem, they are also handsomely profiting from Pill sales. Thus, the burden of compensating those injured by oral contraceptives should properly fall on the manufacturers and be treated as a cost of production. This, in turn, should prompt the manufacturers to initiate more ambitious testing and research programswhich may ultimately result in the development of a convenient, effective and safe Pill.
Large‐Area, Free‐Standing, Two‐Dimensional Supramolecular Polymer Single‐Layer Sheets for Highly Efficient Electrocatalytic Hydrogen Evolution (2015)

The rational construction of covalent or noncovalent organic two-dimensional nanosheets is a fascinating target because of their promising applications in electronics, membrane technology, catalysis, sensing, and energy technologies. Herein, a large-area (square millimeters) and free-standing 2D supramolecular polymer (2DSP) single-layer sheet (0.7-0.9 nm in thickness), comprising triphenylene-fused nickel bis(dithiolene) complexes has been readily prepared by using the Langmuir-Blodgett method. Such 2DSPs exhibit excellent electrocatalytic activities for hydrogen generation from water with a Tafel slope of 80.5 mV decade(-1) and an overpotential of 333 mV at 10 mA cm(-2) , which are superior to that of recently reported carbon nanotube supported molecular catalysts and heteroatom-doped graphene catalysts. This work is promising for the development of novel free-standing organic 2D materials for energy technologies.
An interface agent for attention manipulation [Extended Abstract] (2009)

This paper describes the idea of an interface agent that is able to manipulate the visual attention of a human, in order to support naval crew in a tactical picture compilation task. The agent will consist of four submodels, including a model to reason about a subjectâs attention. In a study (not presented here) a practical case study was formally analysed, and the results were verified using automated checking tools. These results show how a human subjectâs attention is manipulated by adjusting luminance, based on comparative assessment involving a descriptive and a prescriptive model of the subjectâs attention.
Nitric oxide production during focal cerebral ischemia in rats. (1993)

These results suggest that a sharp transient increase in the activity of nitric oxide synthase occurs during the first hour of cerebral ischemia, which leads to a burst in nitric oxide production and activation of guanylate cyclase.
Songs in Women's Journals in the Late Qing Dynasty (2008)

The establishment of the Songs column was a feature of women's journals in the late Qing Dynasty, which undertook the mission of enlightenment, ever since the rise of socialized education for women and music lessons offered in schools for girls in modern China. Based on the records on several different columns in women's journals, this paper presents the actual application and multi influences of the songs in female social life. By dividing the songs into five categories according to their functions and themes, it analyzes their connotations and effects respectively. It also introduces Chen Yi-yi, an editor of three sorts of women's journals, as a representative of songwriters of that period.
Coronary artery bypass surgery without cardiopulmonary bypass*1 (1998)

In the years 1994 and 1995, 1087 patients underwent coronary artery bypass grafting at our institution. Of these, 297 were operated on without cardiopulmonary bypass. 239 were male, and 58 were female. Their ages ranged from 28 to 81 years (54.43 +/- 9.63). Of the total, 294 were operated on electively, two as a coronary reoperations, and one as an emergency after a failed percutaneous transluminal coronary angioplasty procedure. In all patients complete revascularization was the aim, and a cardiopulmonary bypass team was kept on standby. Median sternotomy was performed as the exposure in all patients, except a patient who underwent a coronary reoperation through a left thoracotomy incision. The average of the distal anastomoses was 1.51 +/- 0.6, ranging from 1 to 3. The left internal thoracic artery was used in 292 operations, which was an individual graft in 284, a sequential graft in five, and a free graft in four. Major complications in the early postoperative period were noted in three patients as reoperation for excessive bleeding. One patient had reoperation for left internal thoracic artery spasm, and one patient had lower extremity ischemia caused by intraoartic balloon counterpulsation. Hospital mortality was 0.3% with one patient. It is our belief that in selected cases coronary artery bypass grafting without cardiopulmonary bypass is a safe procedure with the advantage of improvement in recovery during the postoperative period.
Effect of Strain Rate on the Formation of Adiabatic Shear Bands in Ti-6Al-4V (2018)

The effect of strain rate on the formation of adiabatic shear bands in Ti-6Al-4V has been investigated. Quasi-static and high strain rate uniaxial compression and tension experiments were performed on the Ti-6Al-4V specimens over the range of strain rates from 10-3 s-1 to 103 s-1 using a universal testing machine and a Split Hopkinson Pressure Bar. Digital image correlation was used to measure the full-range strain distribution during dynamic tension experiments. Post-mortem microstructural characterisation was performed on recovered specimens utilising optical microscopy. Characterisation and mechanical testing have shown that the material possesses a strong basal texture in the transverse direction (TD). Because of the preferred orientation of the c-axis along the TD, samples in this direction displayed a stronger material behaviour in all loading profiles. Under the condition of uniaxial dynamic compression, the crack length in ASB and bandwidth of ASB increased as a function of strain rate. The as-received Ti-6Al-4V showed the lowest susceptibility to adiabatic shear bands when loaded along the TD direction at strain rates of up to 1600 s-1, whereas the highest susceptibility at a strain rate of 2300 s-1.
