Overheating, flame, smoke, and freight movement detection algorithms based on charge-coupled device camera for aircraft cargo hold surveillance (2004)

We introduce a new approach to aircraft cargo compartment surveillance. The originality of the approach is in the use of a single sensor type, a CCD camera, to detect fire events and freight movement in aircraft cargo holds (multiphenomenom/monosensor approach). The CCD camera evaluation and the radiometric and geometric models are provided in (Sentenac et al., 2002). We go on to discuss the image analysis algorithms used in the detection of fire signatures (hot spots, flame, and smoke) and load displacement. For each phenomenon, the discriminant parameters are established and the algorithm is explained. The crucial factor is the validation procedure according to aeronautical standards. The experimental trials were carried out in a test chamber providing the fire and smoke test facilities [TF1 to TF6 following EN 54 (Afnor, 1997) requirements].
3-Phosphohistidine/6-Phospholysine Phosphatase from Rat Brain as Acid Phosphatase1 (1994)

A phosphatase hydrolyzing 3-phosphohistidine and 6-phospholysine was purified from rat brain cytosol to 90% homogeneity on polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. One milligram of protein of the purified phosphatase released inorganic phosphate from 3-phosphohistidine, 6-phospholysine, AMP, GMP, and p-nitrophenyl phosphate at velocities of 6.5, 15.6, 15.0, 6.9, and 8.3 mumol/min, respectively. However, the purified enzyme could not hydrolyze N omega-phosphoarginine and phosphocreatine, which are substrates for phosphoamidase [EC 3.9.1.1]. The molecular masses of the holoenzyme and the subunit were 94 and 50 kDa, respectively, and the sedimentation coefficient of the native enzyme was 6.3 s, indicating that it was a dimeric enzyme of identical subunits. The enzyme functioned well under acidic conditions, and 50% of the activity was inhibited by 30 microM tartrate, 4 microM vanadate, 20 microM molybdate, 4 microM VCl3, or 13 microM MoCl5. These results indicate that the present hydrolase belongs to the acid phosphatase group [EC 3.1.3.2].
<title>Lens Design Since 1966</title> (1974)

The title of my talk was chosen because in 1966 the Institute of Optics had a Conference on Lens Design With Large Computers. This conference was arranged by Dr. W. L. Hyde and it turns out that it now appears that it was at the peak of the excitement involved in learning how to harness the modern large computer for lens design. Since that heyday, lens designers and interest in lens design has certainly been muted. This present conference is a timely reminder that this remarkable field of physics and engineering is strong and healthy. The people in the field can weather severe economic problems and the uses of lenses in modern technology is steadily in-creasing.
Genetic Influences in Human Substance Abuse (1991)

The importance of clinical studies to genetic research on substance abuse is discussed. This paper compares the advantages and limitations of methods employed in clinical studies to those employed in animal studies. It stresses the complementary nature of human and animal studies for improving our understanding of genetic influences in substance abuse. Finally, it reviews findings from adoption and twin studies of substance abuse. Whereas much is known about genetic influences in human alcoholism, relatively little is known about genetic influences in other types of drug abuse. This disparity is directly related to the amount of research that has been conducted in the two areas over the past several years.
Isolated noncompaction of left ventricular myocardium. A study of eight cases. (1990)

Isolated noncompaction of left ventricular myocardium is a rare disorder of endomyocardial morphogenesis characterized by numerous, excessively prominent ventricular trabeculations and deep intertrabecular recesses. This study comprised eight cases, including three at necropsy. Ages ranged from 11 months to 22.5 years, with follow-up as long as 5 years. Gross morphological severity ranged from moderately abnormal ventricular trabeculations to profoundly abnormal, loosely compacted trabeculations. Echocardiographic images were diagnostic and corresponded to the morphological appearances at necropsy. The depths of the intertrabecular recesses were assessed by a quantitative echocardiographic X-to-Y ratio and were significantly greater than in normal control subjects (p less than 0.001). Clinical manifestations of the disorder included depressed left ventricular systolic function in five patients, ventricular arrhythmias in five, systemic embolization in three, distinctive facial dysmorphism in three, and familial recurrence in four patients. We conclude that isolated noncompaction of left ventricular myocardium is a rare if not unique disorder with characteristic morphological features that can be identified by two-dimensional echocardiography. The incidence of cardiovascular complications is high. The disorder may be associated with facial dysmorphism and familial recurrence.
Three-dimensional coronary reconstruction and endothelial shear stress assessment using frequency domain optical coherence tomography & angiography in humans: comparison with intravascular ultrasound (2013)

Purpose: Realistic 3-dimensional (3D) coronary artery reconstruction is essential to determine local endothelial shear stress (ESS) patterns responsible for atherosclerosis evolution. Intravascular ultrasound (IVUS) has been the mainstay of such studies. Recently introduced Frequency Domain Optical Coherence Tomography (FD-OCT) provides additional high-resolution information. We aimed to develop a method that permits accurate 3D reconstruction from FD-OCT & angiographic data enabling reliable evaluation of the ESS distribution, and to compare the FD-OCT–derived models against the established 3D models based on angiography/IVUS.
Improvement of prognostic performance in severely injured patients by integrated clinico-transcriptomics: a translational approach (2015)

The combination of clinical and transcriptomic markers improves the prognostic performance and may represent a useful tool for individual risk stratification in trauma patients.
The C-type lectin SIGN-R1 mediates uptake of the capsular polysaccharide of<i>Streptococcus pneumoniae</i>in the marginal zone of mouse spleen (2003)

SIGN-R1, a recently discovered C-type lectin expressed at high levels on macrophages within the marginal zone of the spleen, mediates the uptake of dextran polysaccharides by these phagocytes. We now find that encapsulated Streptococcus pneumoniae are rapidly cleared by these macrophages from the bloodstream, and that capture also takes place when different cell lines express SIGN-R1 after transfection. To assess the role of the capsular polysaccharide of S. pneumoniae (CPS) in the interaction of SIGN-R1 with pneumococci, we first studied binding and uptake of serotype 14 CPS in transfected cells. Binding was observed and was of a much higher avidity (3000-fold) for CPS 14 than dextran. The CPSs from four different serotypes were also cleared by marginal zone macrophages in vivo. To establish a role for SIGN-R1 in this uptake, we selectively down-regulated expression of the lectin by pretreatment of the mice with SIGN-R1 antibodies, including a newly generated hamster monoclonal called 22D1. For several days after this transient knockout, the marginal zone macrophages were unable to take up either CPSs or dextrans. Therefore, marginal zone macrophages in mice have a receptor that interacts with capsular pneumococcal polysaccharides, setting the stage for further studies of the functional consequences of this interaction.
Thermodynamics on Landfill Gas Reforming (2009)

Abstract Landfill gas is a type of methane‐rich biogas which supplies renewable resources for clean fuels production. In this paper, the characteristics and optimum conditions of simulated landfill gas and biogas reforming reactions for H 2 production are investigated. The temperature, varied from 373.15 K to 1273.15 K, and pressure, varied from 1.013 bar to 40.013 bar, applied for the reforming system are evaluated. In addition, the effect of steam concentration, traces of hydrocarbons, and the ratio of C/H/O are analyzed using thermodynamic theories. Both the calculation and analyzed results demonstrate that the reforming system is primarily comprised of endothermic reactions. It favors lower pressure and higher temperature. Traces of hydrocarbons would result in a slight increase to CO for this system. A high ratio of CO 2 would result in more production of CO in the reforming process. Preliminary experiments on fuel cells indicate this gas‐reforming simulation is an elementary theory for fuel supply.

Robust Testing of AT&T PMX/StarMAIL Using OATS (1992)

Robust Testing is a systematic test method that uses the OATS (Orthogonal Array Testing System) tool to convert information from product requirements or specifications into a concise set of tests. We found Robust Testing more than twice as productive as conventional testing practices for testing PMX/StarMAIL Release 2.2, a complex private mail exchange (PMX) local area network (LAN)-based electronic mail product that works with several types and versions of LAN software, operating systems, and personal computers (PCs). Robust Testing required less time, enabling us to complete testing on schedule. It found more potentially user-affecting faults, and inspired greater confidence in the quality of the delivered product.
The effect of aspirin on serum indomethacin (1972)

Two studies were conducted to determine the effect of aspirin administration on serum concentrations of indomethacin in human subjects. Indomethacin was determined specifically free of its metabolites by spectrofluorometry following heptane extraction. In Study 1, mean serum indomethacin levels and estimated mean plasma half‐times of elimination after the administration of 50 mg. oral doses to 8 normal volunteers were not significantly changed by concurrent administration of aspirin (3.6 Gm. per day) and indomethacin. Following a fasting dose, mean half‐time without aspirin was 1.82 hours and that with aspirin was 2.24 hours (0.1 > P > 0.05). In Study 2, serum concentration of indomethacin were also unaffected by aspirin administration in patients with arthritis. Thus, claims based on 14 C‐indomethacin radioactivity studies 6 , 20 that an aspirin‐indomethacin interaction is mediated by alterations in serum concentration of indomethacin were not supported.
Optical Defocus Rapidly Changes Choroidal Thickness in Schoolchildren (2016)

The current study aimed to examine the short-term choroidal response to optical defocus in schoolchildren. Myopic schoolchildren aged 8-16 were randomly allocated to control group (CG), myopic defocus group (MDG) and hyperopic defocus group (HDG) (n = 17 per group). Children in MDG and HDG received additional +3D and -3D lenses, respectively, to their full corrections on the right eyes. Full correction was given to their left eyes, and on both eyes in the CG. Axial length (AXL) and subfoveal choroidal thickness (SFChT) were then measured by spectral domain optical coherence tomography. Children wore their group-specific correction for 2 hours after which any existing optical defocus was removed, and subjects wore full corrections for another 2 hours. Both the AXL and SFChT were recorded hourly for 4 hours. The mean refraction of all subjects was -3.41 ± 0.37D (± SEM). SFChT thinned when exposed to hyperopic defocus for 2 hours but less thinning was observed in response to myopic defocus compared to the control group (p < 0.05, two-way ANOVA). Removal of optical defocus significantly decreased SFChT in the MDG and significantly increased SFChT in the HDG after 1 and 2 hours (mean percentage change at 2-hour; control vs. hyperopic defocus vs. myopic defocus; -0.33 ± 0.59% vs. 3.04 ± 0.60% vs. -1.34 ± 0.74%, p < 0.01). Our results showed short-term exposure to myopic defocus induced relative choroidal thickening while hyperopic defocus led to choroidal thinning in children. This rapid and reversible choroidal response may be an important clinical parameter in gauging retinal response to optical defocus in human myopia.
Hypermethylation of P16<sup>ink4a</sup> and P15<sup>ink4b</sup> genes as a marker of disease in the follow‐up of non‐Hodgkin's lymphomas (2000)

The hypermethylation of p16ink4a and p15ink4b genes have been described as an inactivating mechanism alternative to deletions and mutations that accounts for a relatively high proportion of cancers, including non‐Hodgkin's lymphomas (NHLs). To investigate whether detection of abnormal methylation could have clinical applications in the management and follow‐up of lymphomas, we have analysed the behaviour and evolution of p16ink4a and p15ink4b methylation in 13 NHL cases undergoing chemotherapy. All cases were also analysed for the presence of monoclonal rearrangements of immunoglobulin or T‐cell receptor genes. Six patients showed methylation in at least one of these genes at diagnosis, whereas in two other cases methylation appeared during the treatment. The other five cases were always unmethylated. Methylation was detected when any histological or molecular evidence of disease was present, suggesting a good correlation between methylation and disease. In some cases, we were able to detect methylation in patients at complete remission and without evidence of monoclonal cell population, indicating a high sensitivity of the PCR to detect methylation. These results suggest that p16ink4a and p15ink4b methylation could be good markers of disease and could be helpful in identifying lymphoma patients at risk of relapse.
Price recollection and perceived value in restaurants (1995)

This study looks at the relationship of restaurant customers' recollection of what they paid for a meal and their perceived value of that dining experience. For instance, those who experienced the dining occasion as less than adequate remember the amount of the check as less reasonable than it actually was. Customers who thought the restaurant gave them good value recall paying close to what they actually paid.
Surveillance for Nosocomial Infections and Fever of Unknown Origin Among Adult Hematology–Oncology Patients (2002)

Prospective surveillance for NIs on hematology-oncology units should include fever of unknown origin as the single most common and clinically important entity. For a meaningful comparison of surveillance data for hematology-oncology patients, the reported infection rates should include rates based on days with neutropenia, for which days with leukopenia could serve as a surrogate marker under routine conditions.
Ultrasensitive microfluidic solid-phase ELISA using an actuatable microwell-patterned PDMS chip (2013)

Quantitative detection of low abundance proteins is of significant interest for biological and clinical applications. Here we report an integrated microfluidic solid-phase ELISA platform for rapid and ultrasensitive detection of proteins with a wide dynamic range. Compared to the existing microfluidic devices that perform affinity capture and enzyme-based optical detection in a constant channel volume, the key novelty of our design is two-fold. First, our system integrates a microwell-patterned assay chamber that can be pneumatically actuated to significantly reduce the volume of chemifluorescent reaction, markedly improving the sensitivity and speed of ELISA. Second, monolithic integration of on-chip pumps and the actuatable assay chamber allow programmable fluid delivery and effective mixing for rapid and sensitive immunoassays. Ultrasensitive microfluidic ELISA was demonstrated for insulin-like growth factor 1 receptor (IGF-1R) across at least five orders of magnitude with an extremely low detection limit of 21.8 aM. The microwell-based solid-phase ELISA strategy provides an expandable platform for developing the next-generation microfluidic immunoassay systems that integrate and automate digital and analog measurements to further improve the sensitivity, dynamic ranges, and reproducibility of proteomic analysis.
Plesiocystis pacifica gen. nov., sp. nov., a marine myxobacterium that contains dihydrogenated menaquinone, isolated from the Pacific coasts of Japan (2003)

Two strains of a novel myxobacterium (designated SIR-1T and SHI-1) were isolated from Japanese coasts located in the Pacific subtropical zone. Cells of both strains were Gram-negative, rod-shaped and motile by gliding. The strains were chemoheterotrophic and strictly aerobic. They had the common characteristics associated with myxobacteria, such as bacteriolytic action and fruiting-body formation. The characteristic feature of the strains was a NaCl growth requirement with an optimum concentration of 2.0-3.0 % (w/v), comparable to that of sea water. In addition, other cationic components of sea water, such as Mg2+, Ca2+ and K+, were needed for growth. The major respiratory quinone was MK-8(H2). The cellular fatty acid profile was characterized by the predominance of iso-C15:0. Characteristic fatty acids anteiso-C16:0 and anteiso-C17:0, and a long-chain polyunsaturated fatty acid (C20:4), were also detected. The G + C content of the genomic DNA of strains SIR-1T and SHI-1 was between 69.3 and 70.0 mol% (as determined by HPLC). Strains SIR-1T and SHI-1 shared almost identical 16S rDNA sequences, and clustered with the genus Nannocystis as their closest relative upon phylogenetic analysis. However, the phylogenetic distance between the novel strains and the genus Nannocystis was large enough to warrant their different generic allocation. This finding was supported by significant phenotypic differences between the novel strains and Nannocystis. Thus, strains SIR-1T and SHI-1 represent a novel genus and species, for which the names Plesiocystis and Plesiocystis pacifica, respectively, are proposed. The type strain of the species is SIR-1T (=JCM 11591T =DSM 14875T =AJ 13960T).
<title>Direct enzymatic hydrolysis and patterning of a chemisorbed peptide thin film</title> (1997)

We have demonstrated that covalently immobilized enzyme can be used to chemically modify and pattern a chemisorbed peptide film on a solid substrate. The enzyme, alpha- chymotrypsin, was covalently attached to silica and latex spherical beads by glutaraldehyde crosslinking to an amino surface functionality. The fluorescent peptide, suc-ala-ala- phe-AMC (SAAP-AMC) was immobilized to an aminosilane- modified flat silica surface by forming an amide bond to its free carboxylic acid group. SAAP-AMC surfaces were characterized using water wetability, fluorescence spectroscopy and x-ray photoelectron spectroscopy. Upon attack by alpha-chymotrypsin coated beads, the fluorescent AMC group (325 nm ex, 395 nm em) is cleaved from the SAAP- AMC peptide surface and a red-shift occurs in the AMC fluorescence providing a standard marker for enzymatic activity (345 nm ex, 440 nm em). Thus, the signature for alpha-chymotrypsin bead activity against the surface is a reduction in fluorescence intensity from the peptide surface (at 395 nm) and a concomitant increase in fluorescence in the solution above the surface (at 440 nm). Treatment of the SAAP-AMC silica surfaces with alpha-chymotrypsin-beads showed a reduction of the surface fluorescence to background in less than 24 hours, with a corresponding increase of free AMC fluorescence in solution. By restricting the contact region of the beads with the peptide surface we were able to demonstrate chemical patterning of the peptide surfaces.

Pinch Keyboard: Natural Text Input for Immersive Virtual Environments (2001)

Text entry may be needed for system control tasks in immersive virtual environments, but no efficient and usable techniques exist. We present the pinch keyboard interaction technique, which simulates a standard QWERTY keyboard using Pinch Gloves™ and 6 DOF trackers. The system includes visual and auditory feedback and a simple method of calibration.
