EAGLE-a high accuracy 35 GHz tracking radar (2002)

The EAGLE tracking radar family is discussed. EAGLE is a fully coherent tracking radar operating in the 35-GHz band. The radar is unique in the way it combines pulse-to-pulse frequency agility and MTI filtering in a single transmission scheme. A brief comparison of different radar bands is given, and the EAGLE radar, along with its characteristics and techniques is discussed. Test results obtained during field trials are presented. The possibility of using the EAGLE radar for NCTR (noncooperative target recognition) by using a high range resolution mode in the radar is described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Analysis of Transmission Line Directional Couplers (1954)

Five different types of transmission line systems are analyzed and are shown to possess directional properties at the lower radio frequencies. The conditions of mismatch on either transmission line or on both transmission lines have been taken into account, as well as lengths of coupling greater than a fractional wavelength. A new and more general scatter matrix for directional couplers which includes the condition of mismatch is developed. In addition, lumped circuit directional couplers have been developed as a consequence of the general transmission line theory.
Use of Excimer Lasers in the Electronics Manufacturing Industry (1989)

Excimer lasers are finding increasing use in the electronics manufacturing industry. In contrast to other types of laser processing in which material is removed by localised heating, excimer laser processing involves a non‐thermal ablative material removal mechanism. This is due to the ultra‐violet output and short pulse duration of these unique light sources. The result is a high precision means of patterning thin dielectric films, removing such films from metal substrates, or removing thin metal films from underlying dielectrics. Through proper selection of operating parameters it is possible to achieve smooth sidewall profiles with selectable amount of taper while leaving the surrounding and, in the case of film removal, the underlying material virtually untouched. This paper will review the growing use of excimer lasers in applications such as the skiving of access holes and windows in flexible wiring, the drilling of via holes for multilayer boards, the stripping of microwires and other chip bonding applications. The differences between excimer laser processing and conventional laser based techniques will be highlighted.
Comparative proteomic study of two closely related ovarian endometrioid adenocarcinoma cell lines using cIEF fractionation and pathway analysis (2009)

The proteomic profiles from two distinct ovarian endometrioid tumor-derived cell lines, (MDAH-2774 and TOV-112D) each with different morphological characteristics and genetic mutations, have been studied. Characterization of the differential global protein expression between these two cell lines has important implications for the understanding of the pathogenesis of ovarian endometrioid carcinoma. In this comparative proteomic study, extensive fractionation of peptides generated from whole-cell trypsin digestion was achieved by coupling cIEF in the first-dimensional separation with capillary LC (RP-HPLC) in the second dimensional separation. Online analysis was performed using tandem mass spectra acquired by a linear ion trap mass spectrometer from triplicate runs. A total of 1749 and 1955 proteins with protein probability above 0.95 were identified from MDAH-2774 and TOV-112D after filtering through Peptide Prophet/Protein Prophet software. Differentially expressed proteins were further investigated by ingenuity pathway analysis (IPA) to reveal the association with important biological functions. Canonical pathway analysis using IPA demonstrates that important signaling pathways are highly associated with one of these two cell lines versus the other, such as the PI3K/AKT pathway, which is found to be significantly predominant in MDAH-2774 but not in TOV-112D. Also, protein network analysis using IPA highlights p53 as a central hub relating to other proteins from the connectivity map. These results illustrate the utility of high throughput proteomics methods using large-scale proteome profiling combined with bioinformatics tools to identify differential signaling pathways, thus contributing to the understanding of mechanisms of deregulation in neoplastic cells.

Reduction of coherent artifacts in dynamic holographic three-dimensional displays by diffraction-specific pseudorandom diffusion (2004)

An electroholographic display based on diffraction-specific computation can reduce speckle by electronic diffusion through selective addition of a pseudorandom sequence. Intensity fluctuation as a result of the introduction of pseudorandom noise does not affect three-dimensional (3-D) images significantly since spatial windows formed by diffused basis fringes do not widen noticeably at low pseudorandom spread, whereas the features of the fluctuation are much smaller than human visual resolution. Experimental results obtained on the Massachusetts Institute of Technology holographic video system confirmed that the diffusion smooths 3-D images and improves the intensity nonuniformity among horizontal holographic lines.
Pd‐Cu<sub>2</sub>O and Ag‐Cu<sub>2</sub>O Hybrid Concave Nanomaterials for an Effective Synergistic Catalyst (2013)

Palladium and silver salts were combined with Cu2 O octadecahedra in concave heterostructures. The formation of concave faces involved selective oxidative etching of Cu2 O on the {100} faces and in situ growth of Pd/Ag on different sites. The structures showed superior catalytic activities to both single domains and their mixtures in a model Sonogashira-type organic reaction.
Commitment-based approach to categorizing, organizing and executing negotiation processes (2003)

In the current research and development of e-commerce systems, the negotiation process and the enforcement/execution of the results of the negotiation process are often treated as separated business activities. The separation creates an integration problem because these activities should be integral parts of most business transactions. In this paper, we have proposed an approach to categorizing, organizing, and executing negotiation results through business commitments. First, we classify negotiation attributes into 5 categories based on the 5 key elements of news reports. Second, we propose a category-based negotiation process that would allow negotiators to simultaneously bargain on negotiation attributes within an attribute category, and categories of negotiation attributes can be negotiated either sequentially or in parallel. Third, we have described the approach to convert these negotiation attributes into business commitments that are executable in a management platform.
Predictive vector quantization using a neural network approach (1993)

A new predictive vector quantization (PVQ) technique capable of exploring the nonlinear dependencies in addition to the linear dependencies that exist between adjacent blocks (vectors) of pixels is introduced. The two components of the PVQ scheme, the vector predictor and the vector quantizer, are implemented by two different classes of neural networks. A multilayer perceptron is used for the predictive cornponent and Kohonen self-organizing feature maps are used to design the codebook for the vector quantizer. The multilayer perceptron uses the nonlinearity condition associated with its processing units to perform a nonlinear vector prediction. The second component of the PVQ scheme vector quantizes the residual vector that is formed by subtracting the output of the perceptron from the original input vector. The joint-optimization task of designing the two components of the PVQ scheme is also achieved. Simulation results are presented for still images with high visual quality.
Potentiality of embryonic stem cells: an ethical problem even with alternative stem cell sources (2006)

The recent discussions about alternative sources of human embryonic stem cells (White Paper of the US President's Council on Bioethics, 2005), while stirring new interest in the developmental potential of the various abnormal embryos or constructs proposed as such sources, also raise questions about the potential of the derived embryonic stem cells. The data on the developmental potential of embryonic stem cells that seem relevant for ethical considerations and aspects of patentability are discussed. Particular attention is paid to the meaning of "totipotency, omnipotency and pluripotency" as illustrated by a comparison of the developmental potential of three-dimensional clusters of blastomeres (morula), embryonic stem cells, somatic or (adult) stem cells or other somatic (non-stem) cells. This paper focuses on embryoid bodies and on direct cloning by tetraploid complementation. Usage and patenting of these cells cannot be considered to be ethically sound as long as totipotency and tetraploid complementability of embryonic stem cells are not excluded for the specific cell line in question. Testing this poses an ethical problem in itself and needs to be discussed in the future.
Automatic Policy Based Web Service Integration Using Ontology (2016)

Today's rivalry surroundings push the organization to spread out their attention and collaborate with their professional followers to transport the inevitabilities. Service Integration has turned out to be a serious issue as enterprise discovers a better requisite to regularly interact with their professional followers and share their business logics to convey the necessities. But integrating web service logics diagonally different organization leads to exponential problem which lay down developers to grasp the whole web service and must determine appropriate technique to integrate the web services; to merge them which are difficult and time-consuming task. So the current attention is to have a automatic system to investigate the Business logics and deliver the suitable style to integrate them. There is no regular archetypal to carry out these concerns and so this paper proposed a framework which inspects the Business logics independently and recommends proper structure to merge them. One of the proposed advanced models is Policy Evaluation System which examines the service logics and discovers the policies while integrating professional policy assessment of the services and which also examines the Policy Detection Point (PDP) and Policy Enforcing Point (PEP) for more specifically deals with the policy. The proposed Integration model also uses ontology for domain specific knowledge regards policy, policy description and policy priority; this model integrates the required web services without break through Service Level Agreement (SLA).
Denoising Via Nonlinear Image Decomposition for a Digital Color Camera (2007)

To remove signal-dependent noise of a digital camera, we present a denoising approach via nonlinear image-decomposition. In the approach, at the first decomposition stage, multiplicative image-decomposition is performed, and a noisy image is represented as a product of its two components so that its structural component corresponding to a cartoon image approximation may not be corrupted by the noise and its texture component may collect almost all the noise. At the successive denoising stage, the structural component is used instead of the unknown true signal value, to adapt the soft-thresholding-type denoising manipulation of the texture component to the signal dependency of the noise. At the final image-synthesis stage, one combines the separated structure component with the denoised texture component to reproduce a denoised image. The approach selectively removes the signal-dependent noise without not only blurring sharp edges but also destroying visually important textures.
Fe - 36% Ni 인바합금의 표면석출과 산화막 형성에 대한 연구 (1993)

The effect of heat treatment on the surface precipitation of trace impurities and on the subsequent oxidation of an Invar alloy was investigated. An Fe-36% Ni Invar alloy with Mn, Cr, Si, S and C as impurities was heat-treated at 1100˚C in vacuum as well as in 60% N₂＋ 40% H₂gas. Surface analysis with AES, SEM and EPMA has revealed that BN compound and nonmetallic elements such as S, C and O precipitated on the surface of the Invar alloy after a heat treatment in vacuum, while metallic impurities like Mn, Al and Si precipitated as oxide particles especially along grain boundaries after a heat treatment in 60% N₂＋ 40% H₂gas. And it was found that the oxidation occured preferentially near the precipitated nonmetallic and metallic oxide particles. The oxide layers formed on vacuum heat-treated alloys showed the best adherence, while the oxide layers formed without any prior heat treatment spalled on the outer-inner oxide interface.
Database-centered architecture for traffic incident detection, management, and analysis (2002)

This paper presents various issues related to the development of an integrated software architecture for a traffic incident monitoring, mitigation, and analysis system. The novel concept of using a set of distributed databases, having many different functions and types, is proposed for distributed coordination of sensing, control and analysis algorithms. This coordination paradigm using databases makes the whole architecture robust by providing means to efficiently manage current and past states of the monitored environment and the monitoring system. Use of a semantic event/activity database in the integrated architecture also provides high level abstractions through its query language to model traffic incidents and traffic behaviors. We also present experimental results of the use of a concrete database-centered architecture and algorithms in identifying important traffic flow events (such as tail-gating, exit from a ramp, etc.).
An optimal low loss HF diplexer using helical resonators (2003)

A diplexer comprising two narrowband closely spaced channels in the 164-175-MHz band having relatively low insertion loss, small size, and light weight is described. The diplexer replaces a device with dimensions of 6*10*18 in. with one of dimensions 2.2*6*6 in. This order-of-magnitude reduction in size is achieved by the use of optimal asymmetric filters each having poles placed in the other passband giving high mutual isolation, combined with the use of helical resonators giving an unloaded Q on the order of 800, which is about twice as high as previous lumped element filters. Additional out-of-band rejection is obtained by the unusual technique of introducing an additional attenuation pole in the output coupling.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Defective Heparan Sulfate Biosynthesis and Neonatal Lethality in Mice LackingN-Deacetylase/N-Sulfotransferase-1 (2000)

Heparan sulfate is a sulfated polysaccharide present on most cell surfaces and in the extracellular matrix. In vivo functions of heparan sulfate can be studied in mouse strains lacking enzymes involved in the biosynthesis of heparan sulfate. Glucosaminyl N-deacetylase/N-sulfotransferase (NDST) catalyzes the first modifying step in the biosynthesis of the polysaccharide. This bifunctional enzyme occurs in several isoforms. We here report that targeted gene disruption of NDST-1 in the mouse results in a structural alteration of heparan sulfate in most basement membranes as revealed by immunohistochemical staining of fetal tissue sections using antibodies raised against heparan sulfate. Biochemical analysis of heparan sulfate purified from fibroblast cultures, lung, and liver of NDST-1-deficient embryos demonstrated a dramatic reduction in N-sulfate content. Most NDST-1-deficient embryos survive until birth; however, they turn out to be cyanotic and die neonatally in a condition resembling respiratory distress syndrome. In addition, a minor proportion of NDST-1-deficient embryos die during the embryonic period. The cause of the embryonic lethality is still obscure, but incompletely penetrant defects of the skull and the eyes have been observed.
Chemiluminescence immunoassay of cyclosporine in whole blood (1990)

We describe a chemiluminescent immunoassay (CLI) for measuring cyclosporine in whole blood. Its sensitivity and accuracy are comparable with those of an RIA method that makes use of the same specific monoclonal antibody. The comparison with the RIA method was excellent: y(RIA) = x(CLI) + 11.24 (r = 0.99). In our procedure the samples are incubated with cyclosporin C-hemisuccinate-aminobutyl-N-ethylisoluminol, antibody, and paramagnetic particles coated with second antibody. After magnetic separation and washing, the samples are incubated with 200 microL of NaOH (2 mol/L) at 60 degrees C for 30 min. The chemiluminescence generated by automated serial injections of solutions of microperoxidase and dilute (2 mL/L) H2O2 is measured for 5 s. The data are processed by using a spline fit of log B/Bo log conversion. This method is easy to perform and avoids the hazards and costs associated with isotopic waste disposal. The label is stable for at least three years.
Two Scalable Analyses of Compact Attack Graphs for Defending Network Security (2009)

The compact attack graphs implicitly reveal the threat of sophisticated multi-step attacks by enumerating possible sequences of exploits leading to the compromising given critical resources in enterprise networks with thousands of hosts. For security analysts, the challenge is how to analyze the complex attack graphs with possible ten thousands of nodes for defending the security of network. In the paper, we will essentially discuss two issues about it. The first is to compute non-loop attack paths with the distance less than the given number that the real attacker may take practically in realistic attack scenarios. The second is to find the solution to removing vulnerabilities in such a way that given critical resources cannot be compromised while the cost for such removal incurs the least cost. We propose two scalable approaches to solve the above two issues respectively. These two approaches are proved to have a polynomial time complexity and can scale to the attack graphs with ten thousands of nodes corresponding large enterprise networks.
A Dynamic Timing Error Avoidance Technique Using Prediction Logic in High-Performance Designs (2018)

Time borrowing techniques have been widely used to mitigate the timing errors in high-performance designs. A new dynamic flip-flop conversion technique is introduced by Ahmadi et al. (2015) which dynamically converts flip-flops into transparent latches to grant the time borrowing from the next stage and prevent setup time violation. However, it is not able to prevent the timing violation in the successive critical path (SCP) and critical feedback path (CFP) structures. In this brief, we introduce a novel idea of using the output of fast prediction logic of the critical path along with dynamic clock stretching in SCP and CFP structures. The results show that our technique, on average, is able to improve the performance by 20.2% and 14.8% during the prelayout and postlayout simulations, respectively. Furthermore, the proposed technique is almost 7.7% more effective in terms of the performance improvement with only 0.1% area overhead in comparison with the best existing technique.
Simplified Approach to Modelling Traffic Loads on Bridges (2012)

Knowing realistic traffic loading is essential for optimised bridge assessment. A simplified approach to modelling the expected maximum traffic load effects, based on the convolution statistical method, has been proposed. Unlike the traditional method recommended by Moses and Verma (1987) it replaces the indirect calculation of characteristic load effects, through convoluted traffic loads (weights), with a procedure that convolutes the load effects (moments, forces) directly. The emphasis of the procedure is to evaluate accurately the tail of the load distribution histograms, the key factor for correct traffic load modelling, and then to apply a simple, yet sufficiently accurate procedure, applying cumulative distribution functions of the convoluted histograms, to forecast the realistic expected bending moments and shear forces of a bridge. Results of a concrete example, if compared to some alternative procedures, demonstrate that while the computing time is several times faster than for the traditional simulation methods, the results are comparable and conservative in most cases.
Passive microfluidic pumping using coupled capillary/evaporation effects (2009)

Controlled pumping of fluids through microfluidic networks is a critical unit operation ubiquitous to lab-on-a-chip applications. Although there have been a number of studies involving the creation of passive flows within lab-on-a-chip devices, none has shown the ability to create temporally stable flows for periods longer than several minutes. Here a passive pumping approach is presented in which a large pressure differential arising from a small, curved meniscus situated along the bottom corners of an outlet reservoir serves to drive fluid through a microfluidic network. The system quickly reaches steady-state and is able to provide precise volumetric flow rates for periods lasting over an hour. A two-step mathematical model provides accurate predictions of fluid and mass transport dynamics in these devices, as validated by particle tracking in laboratory systems. Precise flow rates spanning an order of magnitude are accomplished via control of the microchannel and outlet reservoir dimensions. This flow mechanism has the potential to be applied to many micro-total analytical system devices that utilize pressure-driven flow; as an illustrative example, the pumping technique is applied for the passive generation of temporally stable chemical gradients.
