Time Delay Modeling and Sample Time Selection for Networked Control Systems (2001)

Abstract This paper discusses the impact of network architecture on control performance in a class of distributed control systems called Networked Control Systems (NCS), and provides design considerations related to control quality of performance (QoP) as well as network quality of service (QoS). The integrated network-control system changes the characteristics of time delays between application devices. This study first identifies several key components of the time delay through an analysis of network protocols and control dynamics. The analysis of network and control parameters is used to determine an acceptable working range of sampling periods in an NCS. A network-control simulator and an experimental networked machine tool have been developed to help validate and demonstrate the performance analysis results, and identify the special performance characteristics in an NCS. These performance characteristics are useful guidelines for choosing the network and control parameters when designing an NCS.
Exploration of Dynamic Web Page Partitioning for Increased Web Page Delivery Performance (2010)

The increasing use of the Internet and demand for real-time information has increased the amount of dynamic content generated residing in more complex distributed environments. The performance of delivering these web pages has been improved through more traditional techniques such as caching and newer techniques such as pre-fetching. In this research, we explore the dynamic partitioning of web page content using concurrent AJAX requests to improve web page delivery performance for resource intensive synchronous web content. The focus is more on enterprise web applications that exist in an environment such that a page's data and processing is not local to one web server, rather requests are made from the page to other systems such as database, web services, and legacy systems. From these types of environments, the dynamic partitioning method can make the most performance gains by allowing the web server to run requests for partitions of a page in parallel while other systems return requested data. This differentiates from traditional uses of AJAX where traditionally AJAX is used for a richer user experience making a web application appear to be a desktop application on the user's machine. Often these AJAX requests are also initiated by a user action such as a mouse click, key press, or used to check the server periodically for updates. In this research we studied the performance of a manually partitioned page and built a dynamic parser to perform dynamic partitioning and analyzed the performance results of two types of applications, one where most processing is local and another where processing is dependent on other systems such as database, web services and legacy systems. The results presented show that there are definite performance gains in using a partitioning scheme in a web page to deliver the web page faster to the user

Review article: the role of antibiotics vs. conventional pharmacotherapy in treating symptoms of irritable bowel syndrome (2007)

Rifaximin is the only antibiotic with demonstrated sustained benefit beyond therapy cessation in irritable bowel syndrome patients in a placebo-controlled trial. Whether antibiotics can improve quality of life in patients with irritable bowel syndrome warrants further research.
Seminal plasma proteins: functions and interaction with protective agents during semen preservation. (2007)

Seminal plasma contains factors that are beneficial and/or detrimental to sperm function and/or storage. However, the nature and characteristics of these factors are not well understood. The major protein fraction (50-70%) of bovine seminal plasma is represented by a family of phospholipid-binding proteins collectively called BSP proteins. The BSP protein signature is characterised by two tandemly repeated fibronectin type 2 (Fn2) domains. It is now well established that BSP proteins and their relatives represent a new emerging superfamily of proteins in mammals. They bind to sperm membrane choline phospholipids at ejaculation. They also bind to capacitation factors, namely, high-density lipoproteins and glycosaminoglycans and promote sperm capacitation induced by these molecules, indicating their beneficial role in sperm function and fertility. In contrast, BSP proteins also induce changes in the sperm plasma membrane by stimulating cholesterol and phospholipid efflux. Thus, the continuous exposure of sperm to seminal plasma that contains BSP proteins is detrimental to the sperm membrane, which may render the membrane very sensitive to sperm storage in the liquid or frozen states. Interestingly, BSP proteins specifically bind low-density lipoproteins present in egg yolk, a compound commonly used in semen extenders. This interaction appears to abolish the detrimental effect of BSP proteins on the sperm membrane. Therefore, BSP proteins in seminal plasma act like a double-edged sword, being both beneficial and detrimental to sperm.
Handling Long Targets and Errors in Sequencing by Hybridization (2003)

Sequencing by hybridization (SBH) is a DNA sequencing technique, in which the sequence is reconstructed using its k-mer content. This content, which is called the spectrum of the sequence, is obtained by hybridization to a universal DNA array. Standard universal arrays contain all k-mers for some fixed k, typically 8 to 10. Currently, in spite of its promise and elegance, SBH is not competitive with standard gel-based sequencing methods. This is due to two main reasons: lack of tools to handle realistic levels of hybridization errors and an inherent limitation on the length of uniquely reconstructible sequence by standard universal arrays. In this paper, we deal with both problems. We introduce a simple polynomial reconstruction algorithm which can be applied to spectra from standard arrays and has provable performance in the presence of both false negative and false positive errors. We also propose a novel design of chips containing universal bases that differs from the one proposed by Preparata et al. (1999). We give a simple algorithm that uses spectra from such chips to reconstruct with high probability random sequences of length lower only by a squared log factor compared to the information theoretic bound. Our algorithm is very robust to errors and has a provable performance even if there are both false negative and false positive errors. Simulations indicate that its sensitivity to errors is also very small in practice.
Tritium Activities in the United States (1995)

There have been many significant changes in the status of tritium activities in the US since the 4th Tritium Conference in October, 1991. The Replacement Tritium Facility (RTF) at Savannah River Site and the Weapons Engineering Tritium Facility (WETF) at the Los Alamos National Laboratory are now operational with tritium. The Tokamak Fusion Test Reactor (TFTR) has initiated a highly successful experimental campaign studying DT plasmas, and has produced more than 10 Megawatts (MW) of fusion power in a D-T plasma. Sandia National Laboratory has ceased tritium operations at the Tritium Research Laboratory (TRL) and many of the activities previously performed there have been transferred to Los Alamos and Savannah River. The tritium laboratory at Lawrence Livermore National Laboratory has reduced the tritium inventory to <5 grams. The Tritium Systems Test Assembly (TSTA) at Los Alamos continues to be at the forefront of tritium technology and safety development for the fusion energy program.
Evaluation of OO7 as a system and an application benchmark (1995)

OO7 has been widely used by developers to benchmark commercial Object Oriented Data Bases (OODB) and by researchers as a realistic workload for experimenting with persistent object systems (POS). These uses of OO7 levy very different requirements; the former needs an application benchmark while the latter needs a system benchmark. This paper describes our experiences with using OO7 both as an application benchmark and a system benchmark. Based on this experience, we outline a framework of the features needed for both kinds of benchmarks. We evaluated OO7 using this framework and found it unsuitable for these tasks. 1 Introduction The construction of many large applications that manipulate complex data structures has motivated significant academic research and industrial development of Object Oriented Databases (OODB) and Persistent Object Stores (POS). In terms of the feature set supported, we will consider an OODB to be a superset of a POS. Both builders and users of such systems wou...
SJSON: A succinct representation for JavaScript object notation documents (2016)

The massive amounts of data processed in modern computational systems is becoming a problem of increasing importance. This data is commonly stored directly or indirectly through the use of data exchange languages, such as JavaScript Object Notation (JSON), for human-readable platform agnostic access. This paper focuses on describing and analyzing SJSON, a library that explores succinct representations of JSON documents as a means to achieve reduced memory usage of files in main memory, and to permit the compression of JSON files stored in disk. In SJSON we represent the document structure with succinct trees, as opposed to the usual pointer-based implementation. Furthermore, the remaining raw data are organized in arrays of attributes and values. Attributes are stripped of redundancies and stored in a simple contiguous array, while values are represented through a bit string indexed array. The scheme here proposed is then evaluated with respect to a number of metrics comparing its performance with popular libraries, anssd possible improvements to the representation are then presented.
Tenomodulin Is Highly Expressed in Adipose Tissue, Increased in Obesity, and Down-Regulated during Diet-Induced Weight Loss (2009)

We conclude that human adipose tissue TNMD gene expression is highly affected by obesity, adipose tissue location, and weight loss, indicating that TNMD may play a role in adipose tissue function.
The Effects of Vehicle Load on Driving Characteristics (2018)

Many traffic accidents are due to an incorrect assessment of the current situation by the driver of the vehicle. With correct assessment of the situation, the driver has also to take into account a number of other factors. This article focuses on some of these factors such as the vehicle load, vehicle speed and curve radius. The first part of the article deals with the position of the vehicle center of gravity (CG), which has a major impact on the driving characteritics of the vehicle. The paper demonstrates the calculation of the maximum speed of a car model and truck model (without load and with load) when cornering. The center of gravity has an effect on the vehicle axles load distribution, and thereby on braking forces. This issue is dealt with in the second part of the paper. In the last part the calculation of the braking force as a function of the adhesion coefficient of the tires depending on the road surface is mentioned. The importance of the contribution consists in quantifying the impact of vehicle load on its driving characteristics.
Bit-error-probability for non-coherent orthogonal signals in fading with optimum combining for correlated branch diversity (2002)

The paper presents an analysis of the bit-error probability for optimal receivers in which the diversity branches are correlated. Non-coherent orthogonal digital modulation (NCODM) with Rician and Rayleigh slow, non-selective fading models are assumed. The maximum likelihood diversity combining laws are derived and simple implementation structure is deduced. The authors find that Rayleigh fading can be better than Rician fading in correlated diversity environments: a situation quite different from the independent diversity case. Also, for the Rayleigh fading model with correlated branch diversity, an equal-weight, square-law combiner usually has the same error performance as the more complex optimum combiner. However, the authors find that this is not the case for a Rician fading model with the same correlation environment. Compensation schemes for the lossy effect of the correlation are designed and found effective when the dominant noise and interference have almost the same correlation distribution as the fading signals. The diagonalization of quadratic forms is used both for error probability analysis and for optimal diversity receiver simplification.
PLC-Optical circulator and isolator based on blazed diffraction grating (2004)

A new type of PLC (Planar Lightwave Circuit)-optical Isolator arranged in a straight line has been successfully fabricated. This device shifts the light propagation direction aside by using blazed diffraction grating, which is realized by MEMS fine fabrication technique. The device is inherently small, and eliminates precise alignment and a magnetic garnet crystal required in conventional bulk devices.
Analysis of Antimicrobial Activity of the Surface of 1B Family Transition Metal Plates (2003)

In order to make the clean antimicrobial surface using metals on which bacteria are too hard to cling and multiply, antimicrobial activity against Saccharomyces cerevisiae, Escherichia coli and Staphylococcus aureus placed on the plate surface of copper, silver and gold which belong to 1B family transition metals has been investigated. The results obtained are summarized as follows: The order of antimicrobial activity was copper>silver>>gold. Copper had the excelent antimicrobial activity against E. coli and S. cerevisiae. Silver had a strong antimicrobial activity against E. coli and a weak one against S. aureus. Gold had a scarce antimicrobial activity. The antimicrobial activity of copper ion against E. coli and S. aureus was weakly found but 640ppm copper ion of a large quantity caused the antimicrobial activity against except S. cerevisiae. 10ppm silver ion caused the antimicrobial activity against all bacteria tested. Contact of copper with E. coli produced a little amount of H2O2 which caused the antimicrobial activity as an oxidizing stress. The mechanism of antimicrobial activity of the surface of 1B family transition metal plates was supposed as following. The synergistic effects of both sterilization ability due to H2O2 produced in very short time from contact of bacteria with the surface of copper plate and oxidizing ability due to copper ion dissolved from the surface of copper plate caused the great antimicrobial activity of the surface of copper plate. Since the quantity of both H2O2 produced and silver ion dissolved from the surface of silver plate was a little, the sterilization ability and oxidizing ability due to silver ion were not so strong as copper's. Consequently, the antimicrobial activity of silver became weaker than copper's. H2O2 produced scarcely from the surface of gold plate and gold did not dissolve at all, so that the sterilization ability and the oxidizing ability did not generate.
Cooperative interactions between replication origin-bound molecules of herpes simplex virus origin-binding protein are mediated via the amino terminus of the protein. (1992)

The virally encoded origin binding protein (OBP) of herpes simplex virus (HSV) is required for viral DNA synthesis. OBP binds at the replication origin to initimultienzyme replication complex (Challberg, M. D., and Kelly, T. J. (1989) Annu Rev. Biochem. 58, 671-717), OBP binds to two sites at the replication origin. The sequence-specific interaction of OBP with each binding site is localized to the major groove, and in both HSV origins the two interaction surfaces are in phase, aligned on the same face of the helix (Hazuda, D. J., Perry, H. C., Naylor, A. M., and McClements, W. L. (1991) J. Biol. Chem. 261, 24621-24625). Using native gel electrophoresis, we now demonstrate that OBP binding to the origin is highly cooperative and that cooperativity requires the putative NH2-terminal leucine zipper. Neither the phase nor orientation of the binding sites affect cooperativity, suggesting that the interaction promotes wrapping of origin DNA around the OBP multimer. A comparison of OBP DNase I footprints with the DNase I footprints of a truncated protein defective in cooperativity demonstrates that the interaction between OBPs bound at sites I and II affects the conformation of the intervening DNA, particularly when the phase or orientation of the two sites is different from wild type. OBP may elicit a unique nucleoprotein structure which facilitates unwinding of the origin and/or assembly of the replication complex. We also demonstrate that OBP can exchange binding sites, forming interduplex complexes. This property may be important for reinitiation of DNA replication.

Polymers for Mobility Control in CO2 Floods (1987)

ABSTRACT The very low viscosity of the displacing fluid is the probable cause of much of the early breakthrough and poor areal sweep efficiency that plagues most applications of CO2 flooding technology. A focussed and already partially successful research program is described, to develop polymers that are soluble in dense CO2 and raise its viscosity sufficiently so that they can be used as direct thickeners for mobility control. Such water-free additives will offer greatly improved displacement efficiencies on both microscopic and macroscopic scales. Developed correlations between molecular structure and solubility in both simple hydrocarbon-CO2 and in polymer-CO2 systems are reviewed. Guided by these, we have synthesized amorphous poly-1-hexenes as a first step towards the preparation of more complex multicomponent polymer systems. Reported in this paper are results on the solubilities and viscosities of various α-olefin polymers in dense lower hydrocarbons such as n-butane and n-propane, which are close to dense CO2 in many solvent properties. Also reported are other experimental details, including the development of gas chromatographic techniques to follow the course of higher α-olefin polymerization, and measurements of molecular weights and molecular weight distribution of the synthesized polymers. It is pointed out that polymers of narrow molecular weight distribution must be used for accurate determination of solubilities in dense CO2.
Ultrasonic surface wave detection by optical interferometry (1973)

The use of optical interferometry for measurement of ultrasonic surface waves has been limited heretofore by the necessity of maintaining the surface under test within a fraction of a wavelength of light of some fixed position. A new technique, using two coherent light beams focused on the specimen surface, avoids this limitation. This technique is useful for directly recording standing-wave ratio, attenuation, transmission, harmonic content, and other characteristics of surface waves at frequencies ranging from audio to beyond 200 MHz. In addition to excellent sensitivity, the method allows absolute calibration of the acoustic wave amplitude.
Towards an advanced magneto-plasmonic sensing platform (2011)

Development of a novel magneto-optic surface-plasmon-resonance (MOSPR) platform and its use for the detection of biomolecules are presented. The physical transduction principle is based on the combination of the magneto-optic activity of magnetic materials and a surface-plasmon resonance of metallic layers. The structure of layers has been optimized using a Transfer Matrix approach. Hints on deposition of thin layers of Cr, Au and Co will be outlined. Such combination can produce a significant enhancement of the magneto-optic effects that strongly depends on the optical properties of the surrounding medium, allowing its use for biosensing applications. Besides the magento-plasmonic sensor, the platform comprises the surface plasmon resonance module, the electromagnet with oscillating magnetic field (with controlled field strength and frequency) for MOSPR and the flow cell with integrated microfluidics. Calibration curves based on solutions with different refractive indices show a steeper slope in the case of the magneto-optical sensor proving an increased sensitivity.
