Smart Design of Stripe-Patterned Gradient Surfaces to Control Droplet Motion (2011)

The motion of droplets under the influence of lithographically created anisotropic chemically defined patterns is described and discussed. The patterns employed in our experiments consist of stripes of alternating wettability: hydrophobic stripes are created via fluorinated self-assembled monolayers, and for hydrophilic stripes, the SiO(2) substrate is used. The energy gradient required to induce the motion of the droplets is created by varying the relative widths of the stripes in such a way that the fraction of the hydrophilic area increases. The anisotropic patterns create a preferential direction for liquid spreading parallel to the stripes and confine motion to the perpendicular direction, giving rise to markedly higher velocities as compared to nonstructured surface energy gradients. Consequently, the influence of the distinct pattern features on the overall motion as well as suggestions for design improvements from an application point of view are discussed.
Modeling of the sub-surface reducing environment of the Z-Area Saltstone disposal facility at the Savannah River Site (2007)

Low-level radioactive liquid wastes at the U.S. Department of Energy Savannah River Site are treated by mixing the wastes with Saltstone grout to generate the Saltstone waste form that is poured into the concrete vaults for long-term disposal. The formula for Saltstone includes ~25 wt% slag to create a reducing environment for mitigating the sub-surface transport of several radionuclides, including Tc-99. A two-dimensional reactive transport model was developed to estimate how long the Z-Area Saltstone will maintain a reducing environment, and therefore its ability to sequester Tc-99. The model predicted that ~16% of the Saltstone reduction capacity would be consumed after 213,000 years. Independent calculations published by other researchers yielded nearly identical results. The general modeling approach and the study results are presented in this paper.
Political Culture and Political Science (1979)

Political culture may be defined as the attitudinal and behavioural matrix within which the political system is located.1 The political culture, that is to say, both expresses and influences the patterns of political belief and behaviour within a given political system: it informs the actions of political actors; comprehends political symbols, foci of identification and fundamental beliefs and values; and generally both reflects and influences popular orientations towards the institutions and practices of government. It is a broader concept than ‘operational code’ or ‘political style’, terms which apply more properly to the actions or assumptions of a particular sub-group of a total population (and particularly to its political leadership); it is a narrower concept, at the same time, than more familiar notions such as ‘national character’ or ‘public opinion’, which have a range of reference much wider than the political system as such. In recent years the concept of political culture has been used with increasing frequency in the comparative analysis of political systems. In this first chapter we shall examine the use of the concept which has been made in the study of one such political system, that of the USSR, and then go on to consider a number of the difficulties with which the employment of the concept has more generally been associated.
One-Dimensional Porous-Silicon Photonic Band-Gap Structures with Tunable Reflection and Dispersion (2000)

The method of fabrication of porous-silicon multilayer structures with periodically modulated porosity was used to obtain one-dimensional photonic band-gap structures with tunable reflection and dispersion. We present the results of transfer-matrix calculations of reflection and dispersion properties of such photonic band-gap structures illustrating the idea of fabricating one-dimensional porous-silicon photonic band-gap broadband reflectors and elements to control parameters of short light pulses. Reflection spectra of the fabricated porous-silicon multilayers indicate that the reflection and dispersion properties of 1D porous-silicon PBG structures can be precisely controlled by varying the parameters of the technological process.
Study on boundary scan interconnect test of PCB based on genetic algorithm (2006)

Test generation is one key technologies of boundary scan. Test set affects test efficiency and results directly. Genetic algorithm (GA) is inducted to boundary scan test in field of DFT (design for testability) in this paper. PCB (printed circuit board) and MCM (multichip module) are taken as project objects to explore an algorithm of GA interconnect test generation. Based on the characteristic of interconnect, the fitness function and genetic operators are put forward. Through the imitation and test in practice for DEMO board developed by us, that shows the algorithm is superior to other algorithms to some extent.
Single Antenna Power Measurements Based Direction Finding (2010)

In this paper, the problem of estimating direction-of-arrival (DOA) of multiple uncorrelated sources from single antenna power measurements is addressed. Utilizing the fact that the antenna pattern is bandlimited and can be modeled as a finite sum of complex exponentials, we first show that the problem can be transformed into a frequency estimation problem. Then, we explain how the annihilating filter method can be used to solve for the DOA in the noiseless case. In the presence of noise, we propose to use Cadzow denoising that is formulated as an iterative algorithm derived from exploiting the matrix rank and linear structure properties. Furthermore, we have also derived the Cramér-Rao Bound (CRB) and reviewed several alternative approaches that can be used as a comparison to the proposed approach. From the simulation and experimental results, we demonstrate that the proposed approach significantly outperforms other approaches. It is also evident from the Monte Carlo analysis that the proposed approach converges to the CRB.

Semantic Integration of Heterogeneous Information Sources Using a Knowledge-Based System (2000)

A growing number of decision support applications require the ability to formulate ad hoc queries that access information from heterogeneous information sources. The Boeing Company recently conducted a study to investigate the feasibility of applying a highperformance knowledge base to interface the information sources to the decision support system. A commercially available knowledge-based development environment provided a number of useful features for this problem including an expressive knowledge representation language, an efficient inference engine, and a large repository of common-sense knowledge. Our objectives were to determine if the pre-stored knowledge would significantly reduce the time required for knowledge engineering in large scale applications, to determine if the domain model was expressive enough to support the wide range of ad-hoc queries typical of our applications, and to determine if the common-sense knowledge would extend the inference power beyond simply combining information from the available data sources.
Inertially Aided GPS Based Attitude Heading Reference System (AHRS) for General Aviation Aircraft (1997)

GPS was used with ultra-short baselines (2-3 car-rier
wavelengths) in a triple antenna configuration to
obtain attitude for General Aviation (GA) aircraft.
Through algorithm selection and error source calibration,
accuracies of 0.1°, 0.15° and 0.2° rms were obtained for
pitch roll and yaw respectively. The accuracy and robust-ness
of the system was enhanced by combining the ultra
short-baseline GPS attitude solution with an attitude solu-tion
derived using inexpensive automotive grade rate
gyros. The solid state gyros allow coasting through tem-porary
GPS outages lasting 2 minutes with attitude errors
less than 6 degrees. The combined GPS-inertial system
has a 20Hz output sufficient to drive glass cockpit type
displays. A prototype system was built and flight tested in
a Beechcraft Queen Air. The system installed and flight
tested in the Queen Air compares favorably to the perfor-mance of the existing vacuum driven instruments. It is cur-rently
being used in ongoing research at Stanford with
futuristic high resolution displays[1].
Lewis(y) antigen stimulates the growth of ovarian cancer cells via regulation of the epidermal growth factor receptor pathway. (2010)

Lewis(y) antigen is an oligosaccharide containing two fucoses, and is expressed variously in 75% of ovarian tumors, where its high expression level predicts poor prognosis. The effect and the possible mechanism of Lewis(y) on the proliferation of human ovarian cancer cells are still largely unkown. We report here that transfecting alpha1,2-FT gene into RMG-I cells increased the expression of Lewis(y) and promoted cell proliferation. In alpha1,2-FT-transfected cells, the Lewis(y) content of EGFR was increased dramatically. Tyrosine phosphorylation of EGFR was elevated. Concomitantly, tyrosine phosphorylation of Akt, ERK1/2 was also upregulated. Moreover, the expression of HER2/neu mRNA and protein, the tyrosine phosphorylation of HER2/ neu were also elveated, while the expression of p27 was significantly reduced. However, the expression of EGFR and the relative content of Lewis(y) on HER2/neu were unchanged. The above-mentioned alterations were correlated with the Lewis(y) content of EGFR and alpha1,2-FT expression in cells. In addition, the phosphorylation intensity and difference in phosphorylation intensity between cells with different expression of alpha1,2-FT were attenuated significantly by the inhibitor of EGFR tyrosine kinase and by the mono-antibody to Lewis(y). Meanwhile, the reduction in p27 and the difference in its expression among the two cell lines were also blocked by the Lewis(y) antibody. The PI3K signaling pathway was more important than the MAPK pathway in the regulation of p27 expression. These findings provide strong evidence that increased expression of Lewis(y) promotes cell proliferation through regulating the phosphorylation and expression of some molecules involved in the EGFR/PI3K-signaling pathway.
Epidemiology teaching and the community perspective. (1993)

In Nicaragua, 2 epidemiologists designed a 6-day course on epidemiology and field research which promoted field and process oriented teaching. The health workers spent 50% of their time working together in groups, 33% in lectures, and 17% in joint sessions. The groups identified research problems in breast feeding, nutritional status, primary health care, and delivery complications. They came up with research objectives, variables, and various study design options. They developed a research protocol which imitated a full-scale study, including sampling frame, sampling methods, and practical field arrangements. They either interviewed people or used retrospective data (interviews or hospital records). They put the data in microcomputers where they were analyzed. The groups merged at the end of the workshop to discuss the group reports. The breast-feeding group identified the problem of not knowing whether women still breast feed for 1.5 to 2 years and what socioeconomic factors affect breast-feeding practices. This group planned a cross sectional study of mothers to determine when they complete breast feeding or whether they breast feed at all and age of child. Data collection included an informed consent, a questionnaire, and a standardized interview. Group members used the life analysis method to determine duration of breast feeding. They learned that 8 months was the median duration of breast feeding and the more educated mothers breast fed for a shorter interval than did the less education mothers. After the course, the medical faculty at Leon University shifted its research emphasis from intramural clinical issues to community-based problems and required a proper research protocol from each student. A year after the course, most participants had taken part in epidemiological studies other than the one in the course and believed the course increased their appreciation of epidemiology, but they also found it to be intensive and some methods and concepts were hard to understand.
Augmented Reality Driving Using Semantic Geo-Registration (2018)

We propose a new approach that utilizes semantic information to register 2D monocular video frames to the world using 3D georeferenced data, for augmented reality driving applications. The geo-registration process uses our predicted vehicle pose to generate a rendered depth map for each frame, allowing 3D graphics to be convincingly blended with the real world view. We also estimate absolute depth values for dynamic objects, up to 120 meters, based on the rendered depth map and update the rendered depth map to reflect scene changes over time. This process also creates opportunistic global heading measurements, which are fused with other sensors, to improve estimates of the 6 degrees-of- freedom global pose of the vehicle over state-of-the-art outdoor augmented reality systems [5]-, [19]. We evaluate the navigation accuracy and depth map quality of our system on a driving vehicle within various large-scale environments for producing realistic augmentations.
Antiferromagnetic Resonance in Mn<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:msub><mml:mrow><mml:mi mathvariant="normal">F</mml:mi></mml:mrow><mml:mrow><mml:mn>2</mml:mn></mml:mrow></mml:msub></mml:mrow></mml:math> (1959)

Measurements of the antiferromagnetic resonance frequency, $\ensuremath{\nu}(T)$, were made on single-crystal slabs of Mn${\mathrm{F}}_{2}$ in the frequency range 96 to 247.2 kMc/sec and at temperatures, $T$, ranging from 4.2\ifmmode^\circ\else\textdegree\fi{}K to 64\ifmmode^\circ\else\textdegree\fi{}K (${T}_{N}=67.7\ifmmode^\circ\else\textdegree\fi{}$K). The results are in general agreement with the resonance relations derived for antiferromagnetic materials by Nagamiya, Keffer, and Kittel, and others. At low temperatures, values of $\frac{\ensuremath{\nu}(T)}{\ensuremath{\nu}(0)}$ and $\ensuremath{\nu}(0)$ are consistent with spin-wave method calculations of the sublattice magnetization and of the value and temperature dependence of the anisotropy energy. This agreement indicates almost complete correlation of adjacent electron spins in the low-temperature range as predicted from spin-wave theory.From the antiferromagnetic resonance measurement of $\ensuremath{\nu}(0)=261.4\ifmmode\pm\else\textpm\fi{}1.5$ kMc/sec and Oguchi's calculation of ${H}_{A}$, $z|J|$ is 3.94\ifmmode\times\else\texttimes\fi{}${10}^{\ensuremath{-}15}$ erg, in agreement with other determinations. Antiferromagnetic resonance line widths were measured from 4.2\ifmmode^\circ\else\textdegree\fi{}K to 64\ifmmode^\circ\else\textdegree\fi{}K. The observed asymmetric line shapes are satisfactorily accounted for as arising from a mixing of absorption and dispersion and from reflections. A simplified line-width theory is given which satisfactorily accounts for the observed line widths except at the lowest temperatures, where a residual width is found. Finally, antiferromagnetic resonance measurements on two crystals, which were grown under different conditions, indicate no difference in resonance frequency or line width.
Epidemic Strategies in Delay Tolerant Networks from an Energetic Point of View: Main Issues and Performance Evaluation (2015)

In this work we investigate Epidemic novel strategies called SNPS and EAER-SNPS applied to a DTN Network. These strategies extend the approach of the basic epidemic routing by using the node density estimation and the nodes energy levels; they adopt the forwarding scheme of the n-Epidemic routing. However, differently from n-Epidemic, it applies a dynamic forwarding scheme based on nodes density, that is able to reduce energy consumption and increase message delivery probability. A deep campaign of simulations was carried out in order to verify the effectiveness of the SNPS and EAER-SNPS. Simulation campaigns were conducted to evaluate the message delivery ratio, the average hop count, the average end-to-end delay and the average residual energy. Different mobility scenarios have been considered through the Working Day mobility model and by simulating pedestrians, buses and cars, in order to see how the performance can degrade on the basis of mobility and nodes characteristics
A Solution Framework for Managing Internet of Things (IOT) (2016)

Internet of Things (IoT) refers to heterogeneous systems and devices (often referred to as smart objects) that connect to the internet, and is an emerging and active area of research with tremendous technological, social, and economical value for a hyper-connected world. In this paper, we will discuss how billions of these internet connected devices and machines will change the future in which we shall live, communicate and do the business. The devices, which would be connected to the internet, could vary from simple systems on chip (SOC) without any Operating System (OS) to highly powerful processor with intelligent OS with widely varying processing capability and diverse protocol support. Many of these devices can also communicate with each other directly in a dynamic manner. A key challenge is: how to manage such a diverse set of devices of such massive scale in a secured and effective manner without breaching privacy. In this paper, we will discuss various management issues and challenges related to different communication protocol support and models, device management, security, privacy, scalability, availability and analytic support, etc., in managing IoT. The key contribution of this paper is proposal of a reference management system architecture based on cloud technology in addressing various issues related to management of IoThaving billions of smart objects.
