[Creating a specific quality-of-life questionnaire in patients with glaucoma: item generation]. (2002)

The methods for developing Health-Related Quality-of-Life (HRQoL) measures and their application in medical research have demonstrated their utility in various chronic, progressive, or life-threatening diseases. The efforts made to allow the patient's perspective to be included in the methodological framework of evidence-based medicine have been successful. The assumption of a strong relationship between clinical status and daily life is certainly valid in ophthalmology. However, there is a lack of specific HRQoL measures dedicated to ophthalmic diseases. Our work aimed at creating the first Glaucoma-specific Quality of Life scale - the Glau-QoL questionnaire - to provide researchers and physicians with a comprehensive, practical, and validated tool. This article describes the first stage of the process, which consisted in generating items and formatting them in order to create a questionnaire that exhaustively covers the relevant concepts. The whole process was conducted by an expert committee including clinicians and methodologists. The standard recommendations in the development of a HRQoL questionnaire were followed: we first identified existing tools and performed a preliminary collection of concepts from the published literature; we then designed an interview guide with the help of clinicians; a trained psychologist interviewed 22 patients at various disease severity stages (from isolated hypertonic to severely impaired); the interviews were tape-recorded and scripted; general domains and related detailed concepts were identified from the script; they were then analyzed and organized; the format of the questionnaire was set up; and questions were derived from the patient's verbatim to capture the identified detailed concepts. The test questionnaire was applied to seven patients for cognitive debriefing. We finally amended the test questionnaire and designed the pilot questionnaire according to the patients' tests and the clinician's review. The test questionnaire was well accepted by the patients, despite a completion duration ranging from 14 to 35 minutes. The pilot questionnaire contained 151 items, grouped into 5 sections: (1) vision problems, physicians, and daily treatment (49 items); (2) activities of daily living (37 items); (3) self-expression (37 items); (4) vision problems and mood (14 items); and (5) other questions (14 items). The next step of our work will be the item reduction process and the psychometric validation of the Glau-QoL questionnaire.
Efficient MAC for Real-Time Video Streaming over Wireless LAN (2015)

Wireless communication systems are highly prone to channel errors. With video being a major player in Internet traffic and undergoing exponential growth in wireless domain, we argue for the need of a Video-aware MAC (VMAC) to significantly improve the throughput and delay performance of real-time video streaming service. VMAC makes two changes to optimize wireless LAN for video traffic: (a) It incorporates a Perceptual-Error-Tolerance (PET) to the MAC frames by reducing MAC retransmissions while minimizing any impact on perceptual video quality; and (b) It uses a group NACK-based Adaptive Window (NAW) of MAC frames to improve both throughput and delay performance in varying channel conditions. Through simulations and experiments, we observe 56--89% improvement in throughput and 34--48% improvement in delay performance over legacy DCF and 802.11e schemes. VMAC also shows 15--78% improvement over legacy schemes with multiple clients.
About The Electromagnetic Theory Of Gratings Made With Anisotropic Materials (1987)

As far as we know, only a few studies have been, up to now, devoted to anisotropic gratings. We only have heard of the paper by our Japanese colleagues of Osaka Prefecture University.1 We are also working in this field, in view of potential applications. Although some partial and unpublished results have been obtained some years ago in the framework of a contract with a private company (P.A. Technology, Cambridge), we think that we have to face a difficult problem which is far from being wholly resolved. We would like to report briefly on our theoretical work in order to inform "practical people" and, should the occasion arise, to initiate new collaborations. Throughout the paper we use a rectangular coordinate system Oxyz and we denote by ex, ey, ez the unit vectors (4, axes Ox, 0y, Oz. We deal with time-harmonic fields represented by complex vectors t and H, using a time dependence in exp(-iwt). The permeability is equal to μ0 everywhere and the relative permittivity is described by a 3 x 3 matrix [6] : xx xy xz [6]yxyy yz zx zy zz We denote by co the vacuum permittiviV, an4 we put ko = wicopo = 27/X0. We say that the fields are TE (or TM) polarized when E (or H) is parallel to Oz.
Decreasing geothermal energy conversion costs with advanced materials (1988)

If the Geothermal Technology Division (GTD) is to meet its programmatic objectives in hydrothermal fluid production and energy conversion, it is essential that new materials of construction be available. Level III Program Objectives include (1) reducing the costs associated with lost circulation episodes by 30% by 1992, (2) reducing the costs of deep wells and directionally dried wells by 10% by 1992, (3) reducing well-cementing problems for typical hydrothermal wells by 20% by 1991, and (4) the development of a corrosion-resistant and low-fouling heat exchanger tube material costing no more than three times the cost of carbon steel tubes by 1991. The Brookhaven National Laboratory (BNL) materials program is focused on meeting these objectives. Currently, work is in progress on (1) high temperature chemical systems for lost circulation control, (2) advanced high temperature (300/sup 0/C), lightweight (approx. 1.1 g/cc), CO/sub 2/-resistant well cementing materials, (3) thermally conductive composites for heat exchanger tubing, and (4) ultra high temperature (600/sup 0/C) cements for magma wells. In addition, high temperature elastomer technology developed earlier in the program is being transferred for use in the Geothermal Drilling Organization programs on drill pipe protectors, rotating head seals, and blow-out preventors. Recent accomplishments and the current status of work in each subtask are summarized in the paper.
Comprehensive Studies on the Magnetic Reversal Properties of Bilayered Magnetic Anti-Dot Lattices (2011)

In this work, we report the results of our study on the magnetization-reversal properties in a bilayered magnetic antidot lattice (BMAL) system consisting of upper perforated thick Co layer of 40 nm and lower continuous thin Ni layer of 5 nm, probed by using a superconducting-quantum-interference-device (SQUID) magnetometer and by magnetic-force microscopy (MFM). Such a BMAL structure was fabricated by using photolithography and controlled wet-etching processes. A systematic study on the in-plane anisotropy, and the switching-field properties was carried out. The atomic-force-microscopy (AFM) image clearly indicated that the anti-dot array structures are well defined, and the local element composition was confirmed by using the energy dispersive spectra (EDS). The room-temperature hysteresis curves, taken along different directions of the applied magnetic-field, were proved to be useful to understand the magnetic anisotropy in the sample. A kind of uniaxial anisotropy with easy axis along 0° and hard axis along 90° of applied field direction was observed. To get a comprehensive knowledge about the domain configuration, we performed the MFM imaging along the easy and hard axis of the lattice. The MFM images revealed well-defined periodic domain networks which can be ascribed to the anisotropies such as magnetic uniaxial anisotropy, configurational anisotropy, etc. The observed changes in the magnetic properties are closely related to the patterning that pins the domains as well as to the magneto-anisotropic BMAL structure.
The Serine/Threonine Kinase Nek6 Is Required for Cell Cycle Progression through Mitosis (2003)

The Aspergillus nidulans protein NIMA (never in mitosis, gene A) is a protein kinase required for the initiation of mitosis, whereas its inactivation is necessary for mitotic exit. Here, we demonstrate that human NIMA-related kinase 6 (Nek6) is required for mitotic progression of human cells. Nek6 is phosphorylated and activated during M phase. Inhibition of Nek6 function by either overexpression of an inactive Nek6 mutant or elimination of endogenous Nek6 by siRNA arrests cells in M phase and triggers apoptosis. Time-lapse recording of the cell cycle progression of cells expressing kinase-inactive Nek6 reveals mitotic arrest at the metaphase stage prior to cells entering apoptosis. In contrast to NIMA and the closely related mammalian Nek2 kinase, which regulate centrosome function and separation, our data demonstrate an important function for Nek6 during mitosis and suggest that Nek6 kinase is required for metaphase-anaphase transition.

We show that if Fermi-liquid effects are neglected the perturbation calculation of Rice yields the same result as the Boltzmann-equation treatment of Bekarevich and Khalatnikov. By considering their limits of applicability the equivalence of the two approaches is established. There is, however, no a priori reason for neglecting Fermi-liquid effects which, through the existence of zero sound modes, are essential for understanding direct measurements of the acoustic impedance.
TF-test Coccidia: New cryptosporidium oocysts diagnostic tool and its applications (2017)

The protozoan genus Criptosporidium is worldwide distributed and is known as an important pathogen.These zoonotic parasites can cause gastric and enteric infections in a long range of vertebrate hosts. To carry out this type of diagnosis, a number of laboratory technical procedures are employed, which basically consist of conventional and commercial kits techniques, which enable the identification of cysts, oocysts, trophozoites and protozoa spores, and as well as eggs and larvae of helminths. However, public and private clinical laboratories that use these technical procedures demonstrate insufficient performance, according to data reported in the literature. Unlike other conventional techniques and commercial kits, the TF-Test or Three Fecal Test technique has been outstanding in recent years with high efficiency in the laboratory diagnosis of human and animal gastrointestinal parasites.

Resource Allocation for FDMA-Based Regenerative Multihop Links (2004)

An approximate but explicit fractional bandwidth and power allocation algorithm for orthogonal regenerative frequency-division multiple-access-based multihop communication systems over ergodic flat-fading channels is presented. The exposed algorithm is assessed for a two-hop scenario, where it is shown to operate within 10% of the optimum resource allocation. The achieved end-to-end capacity is up to 45% higher if compared to a trivial allocation strategy with equal resources.
Time-resolved absolute interferometric measurement of third-order nonlinear-optical susceptibilities (1994)

A modified Mach–Zehnder interferometer has been built for measurement of nonlinear-optical susceptibilities in bulk materials. Both slow- and fast-intensity-dependent refractive-index changes can be measured in absolute value, with femtosecond time resolution, high sensitivity, and precision, by means of a new fringe-locking technique. Results on fast nonlinearities of CS2 liquid and glasses are presented.
Pattern of spread of bloodborne tumour (1986)

The pattern of bloodborne tumour spread has been studied experimentally in syngeneic rats. A variety of tumour types has been injected intravenously, intraportally and also intra-arterially via the left ventricle. Tumour cell arrest as a factor in the localization of metastases in the lung following intravenous injection of cells, and in the liver following intraportal injection, is emphasized. Once tumour cells have entered the arterial circulation they disseminate to almost all organs in similar proportions to the distribution of cardiac output. The dissemination and arrest of cells is not found to correlate with the later distribution of metastases. For example, certain organs (especially the adrenals) which receive only low fractions of injected cells, are always preferred sites for bloodborne metastasis. A strikingly similar pattern of 'arterial metastasis' is also seen for all the tumours used despite their very different histological and biological natures.
RECOMMENDED SPEED INDICATION WITHIN THE MOTOR VEHICLE - A CONTRIBUTION TO FUEL SAVING THROUGH THE "WOLFSBURG WAVE" INFORMATION SYSTEM. ENERGY EFFICIENCY IN LAND TRANSPORT. PROCEEDINGS OF A SEMINAR ORGANISED BY THE COMMISSION OF THE EUROPEAN COMMUNITIES, DIRECTORATE GENERAL FOR ENERGY, LUXEMBOURG, MAY 16-18, 1988 (1989)

The principle behind the wolfsburg wave is to supply drivers in specially equipped vehicles with a steady flow of information about their relative position with respect to the period of the next traffic signal, so that they are able to pass through the intersection while the signal stage is still green by choosing the appropriate speed. This should eliminate or at least significantly reduce the number of stops caused by traffic signals, which in turn would lower fuel consumption and exhaust emissions. In order to gather information on the effects that this wolfsburg wave information system would have on traffic flow and at the same time to measure fuel consumption, 560 test drives were conducted with a specially equipped test vehicle on an approximately 3.6 km stretch of road in wolfsburg. The tests were conducted with the information system switched on as well as off. The before and after studies based on periods with light traffic volume show on the average a significant improvement in the quality of traffic flow as well as a reduction in fuel consumption. To quantify the effects of varying degrees of equipment and acceptance on the quality of traffic flow and the fuel consumption, additional simulation studies were conducted with results indicating tendencies similar to those derived from the empirical measurements. In these tests, the majority of positive effects could already be determined at equipped vehicle quotas of 50%.(a) for the covering abstract of the conference see IRRD 824263.
Ultratrace Analysis of Calcium with High Isotopic Selectivity by Resonance Ionization Mass Spectrometry (1996)

Using resonance ionization mass spectrometric techniques (RIMS) for ultratrace analysis has a number of advantages over conventional techniques: 1. Extremely high sensitivity in the fg to ag range per sample is possible with the high cross sections for optical excitation. 2. Ultrahigh elemental and isotopic selectivity is achieved by the uniqueness of the optical resonance lines of individual elements and isotopes. 3. Background is strongly suppressed by subsequent mass spectrometry. Unfortunately, the application of the technique is complicated by the complexity of the experimental set-up, particularly the laser system, and hence is limited to a small number of research institutes so far.
Maximum likelihood estimation of ground truth for air quality monitoring using vehicular sensor networks (2012)

Various works on vehicular sensor networks (VSNs) for air quality monitoring use solid-state gas sensors due to its low cost and compact form factor. However, solid-state gas sensors have poor selectivity and are sensitive to ambient temperature and relative humidity. In addition, the sensitivity and accuracy of solid-state gas sensors degrade over time due to aging effects. Frequent recalibration of these sensors are required to maintain the accuracy of their measurements. In large VSNs, it is impractical to manually calibrate each node. Thus, calibration must be performed automatically and in-field. Assuming that the gas concentration is homogenous within an area, co-located VSN nodes can either: (1) copy measurements from a highly accurate fixed station in their immediate vicinity, or, in the absence of a fixed station, (2) collaboratively estimate the ground truth. In this work, we use maximum likelihood estimation for determining the ground truth gas concentration in an area by fusing information from co-located sensors in a VSN. Through simulations, we show that the absolute errors of the proposed method has lower mean and standard deviation as compared with existing work.
Characteristics of various synthetic peptide calpain inhibitors and their application for the analysis of platelet reaction. (1991)

Calpeptin (a cell permeable synthetic peptide calpain inhibitor) inhibited the generation of thromboxane B2 (TxB2) by the direct inhibition on Tx synthetase in platelets at the concentrations more than 30 microM. Calpeptin, its analogues and E-64d (EST) were further examined with regard to cell permiability and inhibitory spectra. Among all compounds, only calpeptin inhibited the degradation of substrate proteins of calpain with negligible effect on TxB2 generation in intact platelets at the concentrations less than 30 microM. These concentrations of calpeptin did not inhibit the platelet aggregation, the elevation of [Ca2+], nor the formation of inositol 1,4,5-trisphosphate (IP3) in thrombin or collagen activated platelets. These results indicate that calpain dose not participate in the process of platelet activation induced by thrombin or collagen.
Corrosion Property of API and Modified 13Cr Steels in Oil and Gas Field Environment (1996)

Effects of environmental factors on general corrosion property of API and modified 13Cr steels were systematically investigated. An essential reaction determining the corrosion rate of steels in CO{sub 2} environment is considered to be a direct reduction reaction of carbonic acid. In the absence of a protective film of corrosion product or passivity, the corrosion rate of steels can be written by an Arrhenius-type equation including parameters of activity of carbonic acid and temperature, and using this equation a safety use limit of each steel in various oil and gas environments can be estimated.
Adsorption Behavior of Repulsive Molecules (2005)

Recently, it has been shown that adsorption of gases on solid surfaces often leads to repulsive forces between adsorbate molecules. In this paper, adsorption of molecules on a one-dimensional lattice is considered for repulsive interactions between adsorbate molecules. Exact adsorption isotherms are calculated and analyzed for finite and infinite chains of active sites (i.e., a one-dimensional lattice). Although the mathematical solution for the one-dimensional lattice is known for attractive and repulsive systems, the effects of intermolecular repulsions on adsorption behavior have not been studied in detail previously. Similarly, though the mathematics for the one-dimensional lattice has been solved for any arbitrary lattice length, the effect of finite size on adsorption isotherms for repulsive adsorbate interactions has never been examined. This paper shows that spatial confinement and strong attraction to active sites can cause compression of an adsorbed phase and that repulsive interactions between adsorbed molecules result in steps in the adsorption isotherms. For higher chemical potentials, the density increases until saturating at the lattice capacity. These steps in the adsorption isotherm have not been observed in previous studies of lattice systems. For small lattices, the adsorption behavior was found to be fundamentally different for even and odd values of lattice length. Lattices with an even number of lattice sites can have two steps in the adsorption isotherm, whereas systems with an odd number of sites only have a single step occurring at a coverage slightly greater than half the lattice capacity.
