Towards more usable information flow policies for contemporary operating systems (2014)

There has been a resurgence of interest in information flow based techniques in security. A key attraction of these techniques is that they can provide strong, principled protection against malware, regardless of its sophistication. In spite of this advantage, most advances in information flow control have not been adopted in mainstream operating systems since a strict application of information flow can limit system functionality and usability. Permitting dynamic changes to subject labels, as proposed in the low-watermark model, provides better usability. However, it suffers from the self-revocation problem, whereby read/write operations on already open files are denied because the label of the subject performing these operations has been downgraded. While most applications deal gracefully with security failures on file open operations, they are unprepared to handle security violations on subsequent reads/writes. As a result, subject downgrades may lead to crashes or malfunction. Even those applications that deal with read/write errors may still leave output files in a corrupted or inconsistent state since write permissions were taken away in the midst of producing an output file. To overcome these drawbacks, we propose a new approach for dynamic downgrading that eliminates the self-revocation problem. We show that our approach represents an optimal combination of functionality and compatibility. Our experimental evaluation shows that our approach is efficient, incurring an overhead of a few percentage points, is compatible with existing applications, and provides strong integrity protection.
Overcoming Field Imperfections of Quadrupole Mass Filters with Mass Analysis in Islands of Stability (2009)

We have constructed, and tested as mass filters, linear quadrupoles with added hexapole fields of 4%, 8%, and 12%, with and without added octopole fields. A hexapole field can be added to the field of a linear quadrupole by rotating the two y rods toward an x rod. This also adds an octopole field which can be removed by making the x rods greater in diameter than the y rods. In comparison to conventional quadrupole mass filters these rod sets have severely distorted quadrupole fields, with a mix of both even and odd higher spatial harmonics. They allow evaluating the performance of rod sets with strong geometric and field distortions as mass filters. Conventional mass analysis at the tip of the stability diagram has been compared to mass analysis using islands of stability. The stability islands are produced by applying an auxiliary quadrupole excitation field to the quadrupole. We show that with normal mass analysis at the tip of the stability diagram, the transmission, resolution, and peak shapes are relatively poor in comparison to a conventional rod set. However, the use of islands of stability dramatically improves the resolution and peak shape, and in some cases ion transmission, suggesting that mass analysis with islands of stability may provide a method to overcome a wide range of field imperfections in linear quadrupole mass filters.

A hot probe setup for the measurement of Seebeck coefficient of thin wires and thin films using integral method (2008)

An experimental setup is developed for the measurement of the Seebeck coefficient of thin wires and thin films in the temperature range of 300-650 K. The setup makes use of the integral method for measuring the Seebeck voltage across the sample. Two pointed copper rods with in-built thermocouples serve as hot and cold probes as well as leads for measuring the Seebeck voltage. The setup employs localized heating and enables easy sample loading using a spring loaded mounting system and is fully automated. Test measurements are made on a constantan wire and indium tin oxide (ITO) thin film for illustration. The Seebeck voltage obtained for constantan wire is in agreement with the NIST data for copper constantan couple with an error of 1%. The calculated carrier concentration of ITO film from the Seebeck coefficient measurement is comparable with that obtained by electrical transport measurements. The error in the Seebeck coefficient is estimated to be within 3%.
SYNTHESIS AND CHARACTERIZATION OF THE MBHD COPOLYMER LATEX (2000)

The MBHD copolymer latex with hydroxyl methacrylate(HEMA) and dimethylaminoethyl methacrylate(DMAEMA) was synthesized. The effect of the polymerization conditions and the recipes on the particle size, particle size distribution, viscosity, and the surface tension of the latex was investigated. The results indicate that the latex prepared by batch polymerization process has a smaller particle size, wider particle size distribution(PSD) because more new particle was formed. It also has a higher viscosity and surface tension. An increase in the content of the HEMA and DMAEMA results in the decrease of the surface tension of the latex but it has little effect on the viscosity of the latex. Raising the amount of the HEMA is beneficial to get a smaller particle size and narrower PSD of the latex while the amount of the DMAEMA has an opposite effect on that of the latex. The ratio of the amount of the non ionic to anionic emulsifier, the content of the emulsifiers and the polymerization temperature also has an influence on the properties of the latex prepared by semi continuous polymerization.
The Role of Effective Communication to Enhance Participation in Screening Mammography: A New Zealand Case (2009)

Changes in the organisation of health care have dominated policy initiatives over the past two decades in many countries. An increasing reliance on public health initiatives to prevent or detect disease early has resulted in an increase in programs that screen for cancer in the community. In turn, this accentuates the need to persuasively communicate the value of such initiatives to encourage continued participation. Merely placing screening programs into a community setting is not sufficient to ensure that adequate numbers will voluntarily participate regularly to achieve anticipated cost and mortality savings in the population. In this research the influence of managing communication in a public screening mammography program was investigated. The results revealed that significant opportunities were overlooked for reassurance and information during the physical mammography process. In turn, this highlights the influence of constraints imposed by the structure of the screening program and the resources allocated to the process. This research suggests that it is important to address multiple influences, including ethnic differences, when asking questions about the effectiveness of public health policy, particularly when considering the choices women make about ongoing participation in breast screening programs.
Transparent boundary conditions for parabolic equation solutions of radiowave propagation problems (1997)

Perfectly transparent boundary conditions are derived for truncating the integration domain when solving radiowave propagation problems with a parabolic equation (PE) method. The boundary conditions are nonlocal: they are expressed as a convolution integral involving the field at all previous ranges. The convolution kernel is matched to the refractive index vertical gradient at the boundary. The boundary conditions include an incoming energy term which can model an arbitrary incident field. In particular, they may be used with plane-wave incidence, or with a point-source located below or above the domain boundary. If required, the solution can be extended to heights above the boundary with a generalized horizontal PE method. Closed-form solutions for the incoming energy term are given for plane-wave incidence and for Gaussian sources when the refractive index above the boundary is constant or linear. The resulting finite-difference algorithms provide efficient solutions to problems involving airborne sources. Numerical examples are given, showing excellent agreement with a pure split-step/Fourier PE algorithm.
‘Shape up or ship out': with regard to the remedy (2002)

This articles considers the potential fates of the Chief Executives and board Chairmen of the 12 acute hospital trusts who were awarded no stars in the recently-published league tables. A failure to improve their Trusts’ performance within the time scales given by the Secretary of State (three months for long-serving Chief Executives, and 12 months for those who are newly appointed) could result in their dismissal.
Synthesis and investigation of fullerene-based acceptor materials (2007)

We synthesised a range of new fullerene compounds that showed significantly different photoluminescence quenching abilities in the blends with a polyconjugated polymer; the observed influence of the size and shape of the groups attached to the fullerene cage on the photoinduced charge separation can potentially be used for improvement of power conversion efficiencies in plastic solar cells.
Prevalence of Patients Using Drugs Metabolized by Cytochrome P450 2D6 in Different Populations: a Cross-Sectional Study (2007)

Several patient populations (eg, psychiatric, psychogeriatric, geriatric) have a high prevalence of patients treated with at least one drug metabolized by CYP2D6. This study does not provide evidence regarding the clinical evidence of CYP2D6 genotyping, but shows that, if CYP2D6 genotyping is relevant for patient care, the highest probability of cost-effectiveness will, most likely, be in specific populations.
A 2-tuple fuzzy linguistic representation model for computing with words (2000)

The fuzzy linguistic approach has been applied successfully to many problems. However, there is a limitation of this approach imposed by its information representation model and the computation methods used when fusion processes are performed on linguistic values. This limitation is the loss of information; this loss of information implies a lack of precision in the final results from the fusion of linguistic information. In this paper, we present tools for overcoming this limitation. The linguistic information is expressed by means of 2-tuples, which are composed of a linguistic term and a numeric value assessed in (-0.5, 0.5). This model allows a continuous representation of the linguistic information on its domain, therefore, it can represent any counting of information obtained in a aggregation process. We then develop a computational technique for computing with words without any loss of information. Finally, different classical aggregation operators are extended to deal with the 2-tuple linguistic model.
Detection of Florfenicol Resistance Genes in<i>Escherichia coli</i>Isolated from Sick Chickens (2000)

Florfenicol is an antibiotic approved for veterinary use in cattle in the United States in 1996. Although this drug is not used in poultry, we have detected resistance to florfenicol in clinical isolates of avian Escherichia coli. Molecular typing demonstrated that the florfenicol resistance gene, flo, was independently acquired and is plasmid encoded.
Specificity of protein interactions with highly related SRC homology (SH) domains of FGR and FYN protein‐tyrosine kinases (1994)

As an approach toward identification and isolation of cellular proteins that may act as substrates or effectors of the SRC-family of protein-tyrosine kinases, fusion proteins containing noncatalytic elements of two highly related SRC-family members were tested for their ability to recognize distinct molecules present in lysates of cells known to normally express both enzymes. Our results demonstrate differences of protein binding between the SH2 elements of FYN and FGR kinases, but do not discriminate proteins binding to their SH3 domains.
Large-capacity local access network (1993)

A large-capacity local access network providing users with a dedicated two-way link to a central office is presented. The network is built along a single optical fiber ring. Connection to the fiber is obtained by combining time-division-multiplexing (TDM) and frequency-division-multiplexing (FDM) techniques and by using a novel optical channel add-drop filter. Optical signals are generated at the central office. The users have a simple device integrated with the channel dropping filter to receive and transmit data without the use of an optical source. Such a system can support 210 users transmitting at 100 Mb/s.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Three-Dimensional Reconstruction of Objects Buried in Layered Media Using Born and Distorted Born Iterative Methods (2004)

We develop electromagnetic inverse scattering methods to reconstruct three-dimensional (3-D) objects buried in layered media. The nonlinear inverse problem is solved iteratively via the conjugate-gradient approach; within each iteration, the problem is linearized by Born and distorted Born approximations. The forward solution for layered media is provided by the stabilized biconjugate-gradient fast Fourier transform method. The inversion results from the Born and distorted Born iterative methods are presented, and the effects of the aperture size and noise on the inversion results are also investigated. Numerical results show that these methods are capable of reconstructing an arbitrary 3-D inhomogeneous object buried in a multilayered medium with high resolution.

The renin-angiotensin system and male reproduction: new functions for old hormones (2003)

The blood-borne renin-angiotensin system (RAS) is known best for its role in the maintenance of blood pressure and electrolyte and fluid homeostasis. However, numerous tIssues show intrinsic angiotensin-generating systems that cater for specific local needs through actions that add to, or differ from, the circulating RAS. The male reproductive system has several sites of intrinsic RAS activity. Recent focus on the epididymis, by our laboratories and by others, has contributed important details about the local RAS in this tIssue. The RAS components have been localized morphologically and topographically; they have been shown to be responsive to androgens and to hypoxia; and angiotensin has been shown to influence tubular, and consequently, fluid secretion. Components of the RAS have also been found in the testis, vas deferens, prostate and semen. Angiotensin II receptors, type 1 and, to a lesser extent, type 2 are widespread, and angiotensin IV receptors have been localized in the prostate. The roles of the RAS in local processes at these sites are still uncertain and have yet to be fully elucidated, although there is evidence for involvement in tubular contractility, spermatogenesis, sperm maturation, capacitation, acrosomal exocytosis and fertilization. Notwithstanding this evidence for the involvement of the RAS in various important aspects of male reproduction, there has so far been a lack of clinical evidence, demonstrable by changes in fertility, for a crucial role of the RAS in male reproduction. However, it is clear that there are several potential targets for manipulating the activity of the male reproductive system by interfering with the locally generated angiotensin systems.

Termination and Cost Analysis with COSTA and its User Interfaces (2009)

COSTA is a static analyzer for Java bytecode which is able to infer cost and termination information for large classes of programs. The analyzer takes as input a program and a resource of interest, in the form of a cost model, and aims at obtaining an upper bound on the execution cost with respect to the resource and at proving program termination. The costa system has reached a considerable degree of maturity in that (1) it includes state-of-the-art techniques for statically estimating the resource consumption and the termination behavior of programs, plus a number of specialized techniques which are required for achieving accurate results in the context of object-oriented programs, such as handling numeric fields in value analysis; (2) it provides several nontrivial notions of cost (resource consumption) including, in addition to the number of execution steps, the amount of memory allocated in the heap or the number of calls to some user-specified method; (3) it provides several user interfaces: a classical command line, a Web interface which allows experimenting remotely with the system without the need of installing it locally, and a recently developed Eclipse plugin which facilitates the usage of the analyzer, even during the development phase; (4) it can deal with both the Standard and Micro editions of Java. In the tool demonstration, we will show that costa is able to produce meaningful results for non-trivial programs, possibly using Java libraries. Such results can then be used in many applications, including program development, resource usage certification, program optimization, etc.
Adaptability of Crop Plants to High Temperatures Stress<sup>1</sup> (1982)

The ability of crop plants to adapt to heat stress is potentially an important component of tolerance to heat stress under field conditions. Two genotypes each of bean, potato, and soybean and tomato, with known differences in heat sensitivity as evaluated by their yield and fruit set under high temperature conditions, were used in a study of adaptability of leaf tissues to heat stress. Heat tolerance was measured by 2,3,5‐triphenyl tetrazolium chloride (TTC) reduction and conductivity tests; both methods gave similar results. The degree of heat tolerance could be expressed by either the heat killing temperature or the heat killing time, the latter being the more sensitive indicator. Heat tolerant and susceptible genotypes did not differ in heat killing time when the plants were grown at 20/15 C day/night temperature; however, the differences became dramatic after the plants were acclimated at temperatures above 30 C for 24 hours. Heat killing time was a function of the acclimating temperature with the optimum acclimating temperature found to be 35 to 37 C. Rate of heat acclimation was very fast, and a continuous high temperature treatment appeared to be necessary to retain the high level of heat tolerance. Heat tolerance of leaves was not affected by age when the plants were grown under 20/15 C condition. At 35/35 C, however, the heat tolerance of leaves was lower at the earlier stages and reached a level similar to fully grown plants after 30 days growth. The results suggest that I) the TTC reduction test in addition to the conductivity test can be used to test heat tolerance in crop plants, and 2) screening genotypes that perform well in high temperature environments is feasible at the early stage of growth by testing leaf tissue heat tolerance after the plants have been subjected to a high acclimation temperature, such as 35 C for 12 to 24 hours.
Experimental vapor-liquid equilibria data for binary mixtures of xylene isomers (2005)

Separation of aromatic C8 compounds by distillation is a difficult task due to the low relative volatilities of the compounds and to the high degree of purity required of the final commercial products. For rigorous simulation and optimization of this separation, the use of a model capable of describing vapor-liquid equilibria accurately is necessary. Nevertheless, experimental data are not available for all binaries at atmospheric pressure. Vapor-liquid equilibria data for binary mixtures were isobarically obtained with a modified Fischer cell at 100.65 kPa. The vapor and liquid phase compositions were analyzed with a gas chromatograph. The methodology was initially tested for cyclo-hexane+n-heptane data; results obtained are similar to other data in the literature. Data for xylene binary mixtures were then obtained, and after testing, were considered to be thermodynamically consistent. Experimental data were regressed with Aspen Plus® 10.1 and binary interaction parameters were reported for the most frequently used activity coefficient models and for the classic mixing rules of two cubic equations of state.
Dynamic selection of language models in a dialogue system (2000)

This paper describes a method for building statistical Language Models (LMs) dedicated to specific dialogue situations. The architecture of the speech recognition system proposed uses several LMs. The first stage of this system, consists of producing a word-lattice from a given sentence uttered by a speaker. A general LM calculates a sentence-hypothesis. Then, in a second stage, the system chooses a specialized LM according to the word-lattice and the previous hypothesis. Another decoding process is performed using this specialized LM in order to produce a new sentencehypothesis. Finally, a decision-module processes these two hypotheses in order to assign three confidence levels to the sentence-hypothesis produced. These confidence levels can be used by the dialogue manager in order to improve the dialogue, by asking a confirmation to the speaker when a sentence is labeled ambiguous. This research is supported by France Telecom’s R&D under the contract 971B427.
Female Sterilizations in the United States, 1987 (1989)

A study by the Association for Voluntary Surgical Contraception and the Centers for Disease Control estimated that 640,000 tubal sterilizations were performed in the United States during 1987. The majority of these were inpatient procedures (66 percent) performed in civilian or military hospitals. Hospitals were also the site for the largest share of the 215,000 outpatient procedures. Overall, 33 percent of sterilizations were laparoscopies: 10 percent of the inpatient sterilizations and 79 percent of outpatient procedures. The region with the largest number of sterilizations was the South, which also had the smallest proportion done on an outpatient basis.
