A Computer Software Application for Managing Occupational Exposure Data (1998)

The Health Hazard Information Module is the U.S. Army's computer software application for managing occupational exposure data. The project mission is to utilize automated information systems technology to improve the overall effectiveness of industrial hygiene programs. Field industrial hygiene professionals document their survey methods, findings, conclusions, and recommendations with a portable, pen-based computer. Back at the office, the data are electronically transferred to a desktop workstation. Users can generate standard or customized reports in hard copy or electronic formats. Annually, users transfer their data to a corporate mainframe computer. The software incorporates appropriate information and represents an excellent template worth examining during the ongoing international effort to standardize occupational exposure data. Planned refinements include distributing the software to other Department of Defense agencies and making it commercially available for a nominal fee through the National Technical Information Service in the near future.

Diffusionless Tetragonal–Cubic Transformation Temperature in Zirconia–Ceria Solid Solutions (1993)

Diffusionless tetragonal ( t′ )  cubic ( c′ ) phase transformation in 65‐mol%‐CeO 2 ‐ZrO 2 was investigated around the c′‐t′ equilibrium temperature T 0 c′‐t′ using powder X‐ray diffraction, where c′ was defined as a tetragonal or cubic phase with an axial ratio of unity. The {400} peak profile of t′ ‐ZrO 2 broadened at 860° and 900°C. This indicated that the t′ ‐ZrO 2 transformed partially into c′ ‐ZrO 2 . The {400} peak profile of c′ ‐ZrO 2 also broadened at 860° and 900°C, which indicated that the c′ ‐ZrO 2 partially transformed to t′ ‐ZrO 2 . The finish point of t′→c′ transformation T f t′ → c′ was investigated by annealing the t′ ‐ZrO 2 containing 30–65 mol% CeO 2 at various temperatures. The T′ f t′→c′ line existed in the vicinity of the cubic solubility limit within the t + c two‐phase region. This T f t′→c′ location, which should have been located in the vicinity of T 0 c′‐t′ could not be explained by a simple regular solution model. However, it was described successfully by a thermodynamic model based on Landau's phenomenologic theory.
Effect of eukaryotic initiation factor 4F on AUG selection in a bicistronic mRNA (1991)

Artificial bicistronic mRNAs based on rabbit beta-globin and bacterial chloramphenicol acetyltransferase protein-coding sequences were tested for translation activity in a mouse astrocytoma cell-free extract. This cell extract exhibited an apparent preference for 5'-distal or internal initiation over 5'-proximal ("first AUG") initiation. 5'-Distal initiation appeared to be 5'-cap independent, suggesting that nonstandard initiation was responsible. This conclusion was based on a lack of inhibition of internal initiation by added cap analog and insensitivity of internal initiation to the presence or absence of a 5'-cap structure. Exogenous reticulocyte initiation factors were tested for effect on 5'-proximal initiation. The only factor with a significant effect was found to be eukaryotic initiation factor 4F, or the cap-binding protein. Addition of this factor promoted 5'-end initiation as evident by a general increase in 5'-proximal open reading frame (ORF) product relative to 5'-distal ORF product. The relative expression of 5'-proximal to 5'-distal ORFs in bicistronic or multicistronic mRNAs may very well be dependent on activity levels of eukaryotic initiation factor 4F and possibly other mRNA-dependent initiation factors.
Variants in Scavenger Receptor Class B Type I Gene Are Associated with HDL Cholesterol Levels in Younger Women (2007)

We assessed associations between SCARB1 SNPs and lipid traits in 919 Amish men and women. Two SNPs, rs3782287 and rs5888, were significantly associated with higher HDL-C levels in women younger than 50 years but not in women aged 50 years or older, supporting an interaction between common sequence variants in SCARB1 and estrogen on HDL-C.
A Reexamination of Internationalized Domain Names: The Good, the Bad and the Ugly (2018)

Internationalized Domain Names (IDNs) are domain names containing non-ASCII characters. Despite its installation in DNS for more than 15 years, little has been done to understand how this initiative was developed and its security implications. In this work, we aim to fill this gap by studying the IDN ecosystem and cyber-attacks abusing IDN. In particular, we performed by far the most comprehensive measurement study using IDNs discovered from 56 TLD zone files. Through correlating data from auxiliary sources like WHOIS, passive DNS and URL blacklists, we gained many insights. Our discoveries are multi-faceted. On one hand, 1.4 million IDNs were actively registered under over 700 registrars, and regions within east Asia have seen prominent development in IDN registration. On the other hand, most of the registrations were opportunistic: they are currently not associated with meaningful websites and they have severe configuration issues (e.g., shared SSL certificates). What is more concerning is the rising trend of IDN abuse. So far, more than 6K IDNs were determined as malicious by URL blacklists and we also identified 1,516 and 1,497 IDNs showing high visual and semantic similarity to reputable brand domains (e.g., apple.com). Meanwhile, brand owners have only registered a few of these domains. Our study suggests the development of IDN needs to be re-examined. New solutions and proposals are needed to address issues like its inadequate usage and new attack surfaces.
31P magnetic resonance spectroscopy of human colon cancer. (1990)

Phosphatic metabolite profiles of 19 malignant and normal human colon specimens were analyzed by techniques of perchloric acid extraction and 31P magnetic resonance spectroscopy at 202.4 MHz. Thirty-one individual phosphorus-containing intermediates of metabolism were identified and quantified for statistical intergroup comparisons. Elevations in relative concentrations of phosphorylethanolamine, IMP, NADP 2'-P, an uncharacterized resonance at 3.72 delta, glycerol 3-phosphorylcholine, phosphorylated glycans and the nucleoside diphosphosugars were seen in malignant tissues concurrently with reductions in relative concentrations of phosphorylcholine, phosphocreatine (PCr), and ATP. The malignant and normal tissue groups were further characterized and contrasted by computing metabolic indices from spectral data. Significant elevations in phosphomonoesters, glycerolphosphodiesters, the ratio of phosphorylethanolamine/phosphorylcholine, and phosphomonoesters/inorganic orthophosphate were detected in malignant tissues along with significant reductions in the ratios of PCr/inorganic orthophosphate, PCr/ATP, the energy charge of the adenylate system and the tissue energy modulus. These results revealed significant alterations in high energy metabolism, low energy metabolism, and membrane metabolism characteristic of malignant tissues. The reduction in high energy phosphates ATP and PCr was balanced by the net increase in nucleoside diphosphosugar and a shift in equilibrium to metabolism involving low energy phosphomonoesters. The spectral data of the tumors, which were of epithelial origin, demonstrated minor metabolites not previously detected in tissue extract analysis of malignant tissues. Detection of these minor metabolites represents an indirect measurement of phospholipid metabolism in malignant tissues.

Binary decision diagram with minimum expected path length (2001)

We present methods to generate a Binary Decision Diagram (BDD) with minimum expected path length. A BDD is a generic data structure which is widely used in several fields. One important application is the representation of Boolean functions. A BDD representation enables us to evaluate a Boolean function: Simply traverse the BDD from the root node to the terminal node and retrieve the value in the terminal node. For a BDD with minimum expected path length will be also minimized the evaluation time for the corresponding Boolean function. Three efficient algorithms for constructing BDDs with minimum expected path length are proposed.
Ocean acoustic propagation measurements and wave propagation in random media (1993)

Over the last two decades, observations of acoustic scintillations in the ocean have been useful in testing theories that predict the statistics for WPRM. Ocean acoustic observations differ from scattering processes observed in other WPRM sub-fields in two important ways. First, the statistics of the refractive index can be determined accurately from oceanographic measurements. Hence, exacting tests of theories can be done when careful measurements of the medium and the wavefield are made synoptically. Second, the scattering of acoustic energy is predominantly influenced by the ocean internal wave field, which tends to exhibit statistical stationarity in many ocean regimes, and not by non-stationary turbulent processes, as observed in the atmosphere. We discuss space/time acoustic propagation experiments carried out in three scattering regimes: (1) weak, where the Rytov approximation is valid; (2) moderate, where multiple scattering theory is required; and (3) the case where multiple scattering in a single medium irregularity is encountered. A review is presented of the measurements and comparisons with theory. It is clear from field and numerical experiments that 2-point statistics cannot possibly explain the observations of intensity. Because two-point statistics are the norm when interpreting both medium and wavefield measurements, the possible failure of Gaussian statistics must be addressed. This has yet to be done. We will discuss remaining issues for which we believe further study is needed.
Security Analysis of Mobile Authentication Using QR-Codes (2015)

The QR-Code authentication system using mobile application is easily implemented in a mobile device with high recognition rate without short distance wireless communication support such as NFC. This system has been widely used for physical authentication system does not require a strong level of security. The system also can be implemented at a low cost. However, the system has a vulnerability of tampering or counterfeiting, because of the nature of the mobile application that should be installed on the user's smart device. In this paper we analyze the vulnerabilities about each type of architectures of the system and discuss the concerns about the implementation aspect to reduce these vulnerabilities.
Message Management Systems: Concepts, Motivations, and Strategic Effects (1992)

:This paper motivates the need for system-level message management software. It begins by considering information flows in the workplace as a source of potential gains in efficiency. We next investigate work-flow automation and electronic data interchange (EDI) as indicative of current technologies applied to work processes and message management. Having described current technology and our vision of work processes, we propose an alternative, general-purpose, software technology for supporting application-to-application communication. Problems of EDI, of process-to-process communication, and of describing information items are discussed in terms of the communication problems they present. We then justify the need for this kind of software and layout the criteria (or plausibility conditions) for evaluating a proposal for this sort of system software. The use of a formal communication language is proposed as a common solution to these problems. This proposal is examined in the context of the EDI problem, in order to demonstrate how the proposal might work in practice. Practical benefits of the proposal are discussed that highlight the impact such a technology might have on business practices. The proposed solution is measured against the plausibility conditions presented earlier in the paper; it is found to be sufficient in some cases and in need of further investigation in others. We then discuss the industrial-organizational implications of the availability of such a technology, and hypothesize that it would affect the number and form of cooperative business relationships as well as their scope and depth. We also hypothesize that it would provide advantages to those firms that quickly adopt the technology.
Regulation of expression from the glnA promoter of Escherichia coli in the absence of glutamine synthetase. (1980)

One of the suspected regulators of glutamine synthetase [L-glutamate:ammonia ligase (ADP-forming), EC 6.3.1.2] in enteric bacteria is glutamine synthetase itself. We isolated Escherichia coli strains carrying fusions of the beta-galactosidase structural gene to the promoter of the glutamine synthetase gene, with the aid of the Casadaban Mud1 (ApR, lac, cts62) phage. Some aspects of regulation were retained in haploid fusion strains despite the absence of glutamine synthetase, whereas other aspects required glutamine synthetase catalytic or regulatory activity or both. The direction of transcription of the glutamine synthetase gene was also determined.
Electrostatic interactions as a predictor for osteoblast attachment to biomaterials (2004)

The present study utilizes zeta (zeta)-potential analysis as an indicator of bonding of osteoblasts and whole bone to various biomaterials. Common metal alloys (316L stainless steel, CoCrMo, and Ti6Al4V) and bioceramics (hydroxyapatite and beta-tricalcium phosphate) used in orthopedic applications were suspended in particulate form in physiologic saline, both as-received and supplemented with bovine serum albumin (BSA). Metal alloys were also treated with NaOH washing to study the effect of such a surface treatment on the zeta-potential. The NaOH wash was found to increase the zeta-potential for CoCrMo and Ti6Al4V, but there was a decrease in the magnitude of the zeta-potential for 316L stainless steel. When the metal alloy powders were suspended in BSA-supplemented physiologic saline, the zeta-potential as a function of pH increased, thereby increasing the electronegativity gap and increasing the propensity for bonding between each of the metal alloys and bone. This increase is likely due to matrix proteins in the BSA, which adsorb onto the metal alloy surfaces, promoting bone growth. With the addition of BSA to each bioceramic system, a uniform decrease in zeta-potential was observed. However, the electronegativity gap remained large in each case, maintaining the anticipation of bonding. zeta-Potential analysis is an effective predictor of biomaterial attraction to osteoblasts and bone, providing a useful in vitro method for predicting such interactions.
D/A Resolution Impact on a Poly-phase Multipath Transmitter (2008)

In recent publications the Poly-phase multipath technique has been shown to produce a clean output spectrum for a power upconverter (PU) architecture. The technique utilizes frequency independent phase shifts before and after a nonlinear element to cancel out the harmonics and sidebands due to the nonlinearity. A major advantage of this technique is that it circumvents the need to use dedicated RF filters which makes it a potential candidate for cognitive radio transmitters. This paper addresses the requirements on the digital and mixed signal part of such a transmitter. An architecture is proposed based on complex multiplication which can be used to generate the digital multiphase signals required by the multipath technique. Due to equal phase difference of all the paths the same digital hardware could be utilized for carrying out all the phase shifts. When the digital signals pass through a D/A converter which doesn’t have a reconstruction filter, the output in this case would be amplitude discrete like that of a zero order hold. The spectrum of this amplitude discrete signal would have distortion components in it. This can be termed as quantization distortion but now in the context of limited D/A resolution. The multipath technique’s effect on harmonic cancellation, in the presence of such a quantization distortion is explored in this paper. It is shown through simulation that when using ideal phase shifts the multipath technique is able to cancel most of the harmonics produced by an amplitude discrete representation of pure sinusoids. When (upconversion) mixers are used for the second set of phase shifts then with multipath the highest quantization spurs go down with roughly 8db/bit for a single tone and around 10db/bit for two tone inputs.
Free Radical Polymerization in Aqueous Solution of Acrylic Acid Mediated by Nitroxides Originated from NaNO<sub>2</sub> (1998)

ABSTRACT A series of investigations was carried out focusing on the confinement of the Trommsdorf (gel) effect in radical polymerization of acrylic acid, AA, in its Na-form. Sodium nitrite, NaNO2, functioning at room temperature as an inhibitor for water-soluble monomers, proved to be an effective mediator in polymerizations carried out at t = 90 °C. As a result it was possible to polymerize AA at a high initial monomer concentration, i.e. [M]0 = 40 g/dl. Therefore, concentrated solutions of NaPAA in water were obtainable in a one-step process. It was found that NaNO 2 retards the onset of polymerization up to 60 °C at which temperature only a small degree of conversion α= 30% was reached after 40 hours. On the other hand, without added NaNO2 a less concentrated monomer solution, having [M]0 = 10 g/dl was polymerized to α= 96% at 60 °C after 40 minutes. At 90°C, the polymerization of NaAA no longer appeared to be retarded by sodium nitrite, since in 40 g/dl solutions high degrees of conversion were obtainable within reasonable time periods, without any sign of autoacceleration. As NaNO2 generates nitroxides, it seemed reasonable to analyze the progress of the mediated polymerizations as an approach to “livingness”. In fact, some increase inover time of polymerization, τ, was observed, but generally the criteria for a “living polymerization” remained unfulfilled. Relatively high coefficients of polydispersityranging between 6.50 and 9.62 were found for all the NaNO2 mediated poly(acrylic acid)s. A value of the same order resulted for the non-mediated poly(acrylic acid).
