wshdbg - a debugger for CGI applications (1998)

This contribution discusses wshdbg, an interactive, remote debugger for CGI applications written in pure or derived Tcl-based environments such as websh. The discussion covers a short overview of the websh environment and an analysis of current techniques and impediments of CGI debugging. The debugger presented consists of a client-server architecture, where the server is running on the same host as the Web browser, while the client is included in the CGI application that needs to be debugged. The resulting environment does not provide the level of sophistication known from typical source level debuggers, yet it presents a significant step forward compared to typical CGI debugging techniques which rely on tracing the execution by many log or debug messages. The system has been in operational use in the last two years and proved to be a great help in debugging large Web-based applications, allowing high-level software engineering for Web applications on nearly the same level as it is being done in traditional software development.
Using memory errors to attack a virtual machine (2004)

We present an experimental study showing that soft memory errors can lead to serious security vulnerabilities in Java and .NET virtual machines, or in any system that relies on type-checking of untrusted programs as a protection mechanism. Our attack works by sending to the JVM a Java program that is designed so that almost any memory error in its address space will allow it to take control of the JVM. All conventional Java and .NET virtual machines are vulnerable to this attack. The technique of the attack is broadly applicable against other language-based security schemes such as proof-carrying code. We measured the attack on two commercial Java virtual machines: Sun's and IBM's. We show that a single-bit error in the Java program's data space can be exploited to execute arbitrary code with a probability of about 70%, and multiple-bit errors with a lower probability. Our attack is particularly relevant against smart cards or tamper-resistant computers, where the user has physical access (to the outside of the computer) and can use various means to induce faults; we have successfully used heat. Fortunately, there are some straightforward defenses against this attack.

Children and Families in Health Care:Issues for Advocates (1999)

"In the three years 1993 through 1995, there were 165 million health care visits by children less than 15 years of age, of which 37 million were hospital visits. Eight-five percent of these children were in health care for illness or injury. (NCHS,1998) What happens when these children enter into the health care system? How can we best maximize appropriate care for children?"
Thin-film injection-locked oscillators and negative-resistance amplifiers for 2-GHz radio repeater (1972)

Injection locked oscillators (ILO) used as amplifying stages in a solid-state FM microwave radio repeater are presented. Circuit performances needed for such an application and design criteria used to obtain these performances are given. Two ILO modelling possibilities are analyzed and compared. Similarity between positive feedback model and negative conductance model is shown for circuits with a single resonator. Then the equivalence is extended to a more complex arrangement useful to increase the performances of the practical realization. The first model is still used to study the ILO overall performance and the second model to design the actual circuit. Tunnel-diode ILO with second-order passive network is described giving circuit design criteria and experimental results. Transistor negative conductance linear amplifiers are presented with a procedure for computer aided design of the passive network imbedding the active device. The result of the entire active network is a one-port circuit exhibiting a negative conductance constant with frequency in the whole tuning band. Transistor ILOs are obtained by means of a matching network between circulator and the negative conductance amplifier. Mention is made to the active stages implementation into thin-film microstrip configuration referring alumina thin-film technology.

Higgs Physics (2020)

The existence of the Higgs boson was postulated more than 50 years ago, without any indication of its mass. The quest that followed, with several generations of particle physics experiments, culminated with the recent discovery of a new particle with a mass of 125 GeV. At least another half-century will be needed to map the properties of this particle with sufficient precision to understand its deepest origin.
Principal Component Analysis Applied to 3D Seismic Data for Reservoir Property Estimation (2001)

Summary We apply a common statistical tool, Principal Component Analysis (PCA) to the problem of direct property estimation from three-dimensional (3D) seismic-amplitude data. We use PCA in a novel way to successfully make detailed effective porosity predictions in channelized sand and shale. The novelty of this use revolves around the sampling method, which consists of a small vertical sampling window applied by sliding along each vertical trace in a cube of seismic-amplitude data. The window captures multiple, vertically adjacent amplitude samples, which are then treated as vectors for purposes of the PCA analysis. All vectors from all sample window locations within the seismicdata volume form the set of input vectors for the PCA algorithm. Final output from the PCA algorithm can be a cube of assigned classes, whose clustering is based on the values of the most significant principal components (PC's). The clusters are used as a categorical variable when predicting reservoir properties away from well control. The novelty in this approach is that PCA analysis is used to analyze covariance relationships between all vector elements (neighboring amplitude values) by using the statistical mass of the large number of vectors sampled in the seismic data set. Our approach results in a powerful signal-analysis method that is statistical in nature. We believe it offers data-driven objectivity and a potential for property extraction not easily achieved in model-driven fourier-based time-series methods of analysis (digital signal processing). We evaluate the effectiveness of our method by applying a cross-validation technique, alternately withholding each of the three wells drilled in the area and computing predicted effective porosity (PHIE) estimates at the withheld location by using the remaining two wells as hard data. This process is repeated three times, each time excluding only one of the wells as a blind control case. In each of the three blind control wells, our method predicts accurate estimates of sand/shale distribution in the well and effective porosity-thickness product values. The method properly predicts a low sand-to-shale ratio at the blind well location, even when the remaining two hard data wells contain only high sand-to-shale ratios. Good predictive results from this study area make us optimistic that the method is valuable for general reservoir property prediction from 3D seismic data, especially in areas of rapid lateral variation of the reservoir. We feel that this method of predicting properties from the 3D seismic is preferable to traditional, solely variogram-based geostatistical estimation methods. Such methods have difficulty capturing the detailed lithology distribution when limited by the hard data control's sampling bias. This problem is especially acute in areas where rapid lateral geological variation is the rule. Our method effectively overcomes this limitation because it provides a deterministic soft template for reservoir-property distributions.
Potential ground water and surface water impacts from oil shale and tar sandsenergy-production operations. (2006)

heat, and radioactivity on the solids and fluids of hydrocarbon deposits, the nature and extent of induced fractures in different rock media, and the possibility of isolating and confining or removing radioactive contaminants. Final technical feasibility can only be determined by a field test. If technical feasibility is established, economic feasibility will depend upon the comparative cost of producing hydrocarbons by nuclear explosives and by conventional means. It is probable that an economic comparison would favor nuclear stimulation only where devices of relatively high yield could be used practicably and safely.
Determination of nitrate in soil pastes by ion selective electrodes (1977)

Abstract An ion selective electrode was used to measure the nitrate ion concentration in pastes of soil and saturated calcium sulphate solution. A good correlation, for both air‐dried and field‐moist soil samples, was obtained between nitrate values found by colorimetric analysis subsequent to KC1 extraction, and those found by a nitrate electrode, non‐porous reference electrode couple. A ceramic frit reference electrode, although effective in pastes of air‐dried soils, gave rise to erroneous results in pastes of field‐moist soils.
Analyzing the reuse potential of migrating legacy components to a service-oriented architecture (2006)

An effective way of leveraging the value of legacy systems is to expose their functionality, or subsets of it, as services. In the business world, this has become a very popular approach because it allows underlying systems to remain largely unchanged, while exposing functionality to a larger number of clients through well-defined service interfaces. The U.S. Department of Defense (DoD) is also adopting this approach by defining service-oriented architectures (SOAs) that include a set of infrastructure common services on which organizations can build additional domain services or applications. When legacy systems or components are to be used as the foundation for domain services, there must be an analysis of how to convert the functionality in existing systems into services. This analysis should consider the specific interactions that is required by the SOA and any changes that need to be made to the legacy components. We have recently helped an organization evaluate the potential for converting components of an existing system into services that would run in a new and tightly constrained DoD SOA environment. This paper describes the process that was used and outlines several issues that need to be addressed in making similar migrations
On‐site detection of plant pathogens using lateral‐flow devices* (2000)

One‐step lateral‐flow tests have been developed for the on‐site detection and identification of several plant viruses. They utilize specific monoclonal and polyclonal antibodies in an immunochromatographic format, incorporating antibody‐coated latex particles. These tests have been combined with a novel extraction procedure to allow disease diagnosis in the field within 3 min. Lateral‐flow devices for two potato viruses ( Potato Y potyvirus and Potato X potexvirus ) have been demonstrated as being 100% accurate in preliminary trials, when compared with traditional microplate enzyme‐linked immunosorbent assays. This paper reviews the techniques currently employed for on‐site detection of plant pathogens. The development of lateral‐flow devices is described and their possible impact on plant disease diagnosis is discussed.
The doubly terminated lossless digital two-pair in digital filtering (1985)

A digital lossless two-pair terminated at both ends with "passive" multipliers is studied. Conditions for low sensitivity of the transfer-function magnitude with respect to the digital multiplier coefficients are derived. It is shown that low sensitivity property can be achieved by forcing certain "matching" conditions, at the terminations. The application of these results to the understanding of some well-known digital filter structures is outlined. In particular, it is shown that the coupled-form biquad can be interpreted as a doubly terminated lossless digital two pair, and that it satisfies the "termination matching conditions" for almost all pole locations. All results derived in the paper are based on independent <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">z</tex> -domain arguments.
Theft and Vandalism Control Measures on Building Sites in Lagos, Nigeria (2013)

Problems of theft and vandalism is paramount issues related to building sites. The incidence of theft and vandalism sometimes depend on the nature of construction work and these vary among housing developments, roads and highways construction, dam structures, airport, and stadia construction. This study investigates the nature of theft & vandalism and security control on building site to curb the endemic effect through diversity of security technologies. A purposive sampling technique was adopted for the study. Opinion survey questionnaires were administered to construction professionals in the three categories of construction firms; large construction, medium construction and small construction firms and literature was also reviewed. The data collected was analysed using both descriptive and inferential statistics. Study revealed that more theft and vandalism are experienced large construction firms than medium and small firms. Construction professionals agree to identify causes of losses and considered all security component/ measures to be important.
MMS19 is required for NER and transcription in human cells (2008)

854 Yeast MMS19 encodes a polypeptide necessary for effective nucleotide excision repair (NER) and RNA polymerase II (Pol II) transcription. We have previously reported that human MMS19 is able to complement the NER and RNA Pol II transcription phenotypes of a yeast mms19 deleted strain. Human MMS19 associates with TFIIH by interacting with XPB and XPD, however, the precise functions of MMS19 in mammalian cells have not yet been established.  To determine the functions of MMS19 in mammalian cells we altered the levels of MMS19 in human normal cells by using short interfering RNA (siRNA). MMS19 expression was quantified by RT-PCR and western blotting. Cells expressing normal and low levels of MMS19 were exposed to ultraviolet (UV) radiation and high temperature. Cell viability after UV radiation and incubation at high temperature was analyzed by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. UV dose-dependent survival was measured by colony forming ability. The time required for the in vivo removal of UV-induced cyclobutane pyrimidine dimers (CPDs) after UV radiation was determined by NER immunoassay using monoclonal antibodies.  Our data show that human cells with siRNA-mediated depletion of MMS19 have significant decrease in cell viability after either UV radiation or incubation at high temperature. A significant decrease in the removal of CPDs after UV radiation was also observed in MMS19 knockdown cells.  These findings show for the first time that, in human cells, MMS19 protein is required for the effective removal of the UV-induced DNA damage and for efficient transcription at high temperature. Furthermore, our data suggests that the level of MMS19 expression might predict the ability of human cells to survive stress such as exposure to DNA damaging agents and high temperature. These findings might have important implications from human aging to cancer therapy.
The Perception of Arrival Time for Different Oncoming Vehicles at an Intersection (1994)

We make an appeal to bring the theoretical tools of ecological psychology to focus on road-traffic accidents that result from making left turns. Following a review of previous arrival-time literature, we report an experiment that was conducted in a fixed-base driving simulator to determine the perceptual basis for judgments to turn left. We manipulated the arrival time (Ta) of an oncoming vehicle, the viewing distance to that vehicle, and the type of oncoming vehicle. Forty-eight participants were randomly assigned to a group in which a motorcycle, a compact car, a full-size car, or a delivery truck represented the oncoming vehicle. There were equal numbers of male and female participants in the four groups. As Ta, was increased, underestimation of vehicle Ta also increased. Significant main effects were found for Ta, gender of participants, vehicle type, and viewing distance; significant effects were also found for interactions for gender by Ta and gender by vehicle type. Men and women differed in their accuracy of judgments for vehicle types; men were more accurate in estimating the arrival of delivery vans and motorcycles than women. The accuracy of Ta estimation for the type of the approach vehicle and distance removed suggests that participants used vehicle-size information in their judgments. We present a discussion of a number of "disappearancen methodological issues and research applications.
PITT at TREC 2011 session track (2011)

In this paper, we introduce our approaches for TREC 2011 session track. Our approaches focus on combining different query language models to model information needs in a search session. In RL1 stage, we build ad hoc retrieval system using sequential dependence model (SDM) on current query. In RL2 stage, we build query language models by combining SDM features (e.g. single term, ordered phrase, and unordered phrase) in both current query and previous queries in the session, which can significantly improve search performance. In RL3 and RL4, we combine query model in RL2 with two different pseudo-relevance feedback query models: in RL3, we use top ranked Wikipedia documents from RL2’s results as pseudo-relevant documents; in RL4, snippets of the documents clicked by users in a search session are used. Our evaluation results indicate: texts of previous queries in a session are effective resources for estimating query models and improving search performance; mixing query model in RL2 with the query model estimated using click-through data (in RL4) can improve performance in evaluation setting that considers all subtopics, but no improvement is observed in evaluation setting that considers the only subtopic of current query; our methods of mixing query model in RL2 with query model in RL3 did not improve search performance over RL2 in any of the two evaluation settings.
Phagocyte Function in the Neonate: Selected Aspects (1979)

It has become evident that a number of developmental deficiencies exist in the function of neonatal phagocytes. Although the degree to which each contributes to the recognized impairment of host defenses in the normal human neonate is yet unclear, we have derived much valuable information from the study of neonatal polymorphonuclear leukocytes (PMNs) and monocytes (MNLs). In this discussion, we focus upon three functional components of PMN—phagocytosis, bactericidal activity, and movement. This is followed by a brief consideration of correlative studies between neonatal PMNs and MNLs. A more detailed discussion of monocyte functions is found elsewhere in this symposium. PMN PHAGOCYTOSIS As with many in vitro systems, phagocytic assays vary considerably in design. Included among the important variables are cell concentration, opsonic concentration, type of particle being ingested, and phagocyte:particle ratio. Despite these differences, results obtained by most investigators studying neonatal PMNs have been reasonably consistent. The data fall into two groups. In the first, PMN phagocytosis has been studied in the presence of normal, or approximately normal plasma (or serum) concentration.1-5 In general, such experiments have yielded data suggesting that the neonatal PMN is equal to the adult PMN in phagocytic ability. A number of particles have been utilized in these studies, including Staphylococcus aureus 502A, Serratia marcescens, Sta pyogenes, Diplococcus pneumoniae, and Pseudomonas aeruginosa. The second group of studies has been carried out under "stress" conditions in vitro or in vivo, and suggest that the neomatal PMN is deficient in phagocytic ability when compared with that of the adult PMN.
A base-sequence-modulated golay code improves the excitation and measurement of ultrasonic guided waves in long bones (2012)

Researchers are interested in using ultrasonic guided waves (GWs) to assess long bones. However, GWs suffer high attenuation when they propagate in long bones, resulting in a low SNR. To overcome this limitation, this paper introduces a base-sequence-modulated Golay code (BSGC) to produce larger amplitude and improve the SNR in the ultrasound evaluation of long bones. A 16-bit Golay code was used for excitation in computer simulation. The decoded GWs and the traditional GWs, which were generated by a single pulse, agreed well after decoding the received signals, and the SNR was improved by 26.12 dB. In the experiments using bovine bones, the BSGC excitation produced the amplitudes which were at least 237 times greater than those produced by a single pulse excitation. The BSGC excitation also allowed the GWs to be received over a longer distance between two transducers. The results suggest the BSGC excitation has the potential to measure GWs and assess long bones.
Parallel synthesis of muramyl peptides derivatives (2005)

N-acetyl muramyl-L-alanyl-D-isoglutamine (MDP) is the minimal structure for the irnmunoadjuvancy elicited by Freund's Complete Adjuvant [1]. Although MDP has wide biological activities, its application is limited due to its short duration of action and undesired side effects [2]. In our attempt to study structure-activity relationships as well as to dissociate between immunomodulatery and other unwanted biological activities, we prepared 46 MDP derivatives in which organic acids were separately linked to the C terminal of MDP or to the C termirial of MDP’s isomers: N-acetyl isomuramyl-L-alanyl-D-iso-glutamine through a bridge. As the generation of molecular diversity through combinatorial synthesis promises to be more efficient [3, 4, 5], and the solid phase approach offers a number of advantages over solution phase methods. We constructed the small library of MDP derivatives on solid phase with multipin kits [6]. Screening for biological activities of these compounds is in progress.
