A 1.5- mu m laser package frequency-locked with a novel miniature discharge lamp (1991)

The authors report a packaged distributed feedback (DFB) laser frequency-locked to the Kr 1s/sub 2/-2p/sub 8/ transition at 1.54782 mu m using a novel miniature discharge lamp. This transition is not only close to the wavelength where typical single-mode optical fibers show minimum attenuation but also gives a large optogalvanic signal. This lamp generates more than an order of magnitude larger optogalvanic signal for the same input power than conventional indicator lamps of comparable size. The frequency stability of the laser package is better than 2 MHz, and the fiber-to-laser coupling loss (<2 dB) is very stable against temperature fluctuations and mechanical vibrations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

An Autopsy Case of Familial Neuronal Intranuclear Inclusion Disease with Dementia and Neuropathy (2018)

Neuronal intranuclear inclusion disease (NIID) is a rare neurodegenerative disease with marked variety in its clinical manifestations. While characteristic neuroimaging and skin biopsy findings are important clues to the diagnosis, autopsy studies are still important for confirming the exact disease features. We herein report the case of a patient who received an antemortem diagnosis of familial NIID with dementia-dominant phenotype that was later confirmed by an autopsy. Our report is the first to document a case of autopsy-confirmed NIID involving both cognitive impairment and sensorimotor neuropathy.
Micro-opto-electro-mechanical systems: recent developments and LETI's activities (2000)

The spectacular growth in MOEMS interest is highlighted by the involvement of R&D centres and industrial companies. A lot of application fields offer large opportunities for Micro-Opto-Electro- Mechanical Systems (MOEMS): optical communications (switches, cross- connect matrix, DWDM systems ...), digital image processing, adaptive optics... but also industrial maintenance, environment, medicine,... After general ideas on MEMS and MOEMS, this paper presents the main application fields for MOEMS and a few outstanding devices are presented to illustrate the recent developments. Then the work of LETI in MOEMS is presented. Some devices are fabrication with MEMS technologies such as tunable Fabry-Perot interferometers for DWDM telecommunications or 2D micro-scanners for obstacle detection. But a more specific technology has also been developed by LETI, resulting in devices made of silica such as 1D micro-scanners for obstacle detection. Moreover some devices are constituted of micro-mechanical structures combined with Integrated Optics: micro-switches for protection applications and network reconfiguration in optical communications, micro-vibration sensor for surveillance of rotating machines in electrical generators.

Use of ELSD detector allowed the detection and quantification of the substrates and the reaction products of enzymatic synthesis of the surfactant, N-lauroyl-N-methylglucamide. The developed HPLC method has acceptable environmental profile based on HPLC-EAT evaluation.
Room temperature electroluminescence from a c-Si p-i-n structure (2001)

The time dependent electroluminescence (EL) of c-Si (at 1.1 eV) is investigated at room temperature for a p-i-n structure under excitation with forward biased current pulses. The EL intensity increases by square law at shorter times (&lt;3 μs) and reaches a steady state value at longer times (&gt;10 μs). The parabolic dependence of the EL intensity on the current density at the shorter times points to the bimolecular recombination mechanism. The EL response time has been decreased to less than 200 ns for the given p-i-n structure by application of a reverse bias potential. The maximal EL quantum efficiency is of the order of 0.01% for the investigated p-i-n structure and possible ways to increase this value are discussed.
Fabrication of vertical mirrors using plasma etch and KOH:IPA polishing (2006)

A new approach to etch structures with vertical sidewalls in Si is presented in this paper. This process reduces the loading effect in deep reactive ion etching (DRIE) and maintains a uniform etch profile and etch rate throughout the wafer. Shallow areas were patterned under the regions to be removed. The wafer was then bonded to a pyrex wafer which acts as a handle wafer and as a package lid for packaging MEMS devices. Uniform width narrow channels encompassing these shallow patterns were then subjected to long through wafer DRIE. These narrow channels maintain uniform etch rates while patterning structures with various fill factors on the same wafer. Various structures were etched with vertical side walls across the 550 µm thick Si wafer. Average side wall angles of 89.8° were obtained with just 0.3° variation across the 4'' Si wafer. The process showed resistance to slight variations in DRIE parameters with a negligible effect on the sidewall profile. Additionally, the verticality of the structures was improved to 90.08° by performing KOH:IPA wet etching on the plasma etched surfaces. Once characterized, the same processes can be used for various shape/size structures. These etched vertical mirrors were used to assemble a corner cube retroreflector.
Isolation and characterization of HIV-2 from an AIDS patient in Ghana (1988)

This report describes the isolation and characterization of a retrovirus of the HIV-2 group from a Ghanaian AIDS patient which has different restriction patterns from previously reported HIV-2 viruses. The virus was morphologically very similar to HIV-1 and HIV-2, and had Mg2+-dependent reverse transcriptase. Like previous HIV isolates, it induced severe cytopathic effects in CD4-positive human lymphoid cell lines. Its major proteins were shown to be gp110, p66, p55, p41, gp32, p30 and p26 by Western blot analysis. In dot-blot hybridization experiments, the virus hybridized with a HIV-2 DNA probe, but not with HIV-1 and SIVagm probes in stringent conditions. These data indicate that this Ghanaian virus is a HIV-2 group virus. However, in a Southern blot hybridization experiment, the restriction patterns of this virus, designated HIV-2 [GH-1], were quite different from those of previously reported HIV-2 viruses from West Africa isolated at the Pasteur Institute.
Thermal resistance and inactivation of Enterobacter sakazakii isolates during rehydration of powdered infant formula. (2007)

Enterobacter sakazakii may be related to outbreaks of meningitis, septicemia, and necrotizing enterocolitis, mainly in neonates. To reduce the risk of E. sakazakii in baby foods, thermal characteristics for Korean E. sakazakii isolates were determined at 52, 56, and 60 degrees C in saline solution, rehydrated powdered infant formula, and dried baby food. In saline solution, their D-values were 12-16, 3-5, and 0.9-1 min for each temperature. D-values increased to 16-20, 4-5, and 2-4 min in rehydrated infant formula and 14-17, 5-6, and 2-3 min in dried baby food. The overall calculated z-value was 6-8 for saline, 8-10 for powdered infant formula, and 9-11 for dried baby food. Thermal inactivation of E. sakazakii during rehydration of powdered infant formula was investigated by viable counts. Inactivation of cultured E. sakazakii in infant formula milk did not occur for 20 min at room temperature after rehydration with the water at 50 degrees C and their counts were reduced by about 1-2 log CFU/g at 60 degrees C and 4-6 log CFU/ml with the water at 65 and 70 degrees C. However, the thermostability of adapted E. sakazakii to the powdered infant formula increased more than two times. Considering that the levels of E. sakazakii observed in powdered infant formula have generally been 1 CFU/100 g of dry formula or less, contamination with E. sakazakii can be reduced or eliminated by rehydrating water with at least 10 degrees C higher temperature than the manufacturer-recommended 50 degrees C.
Review: Predicting response to anti-TNF agents for the treatment of Crohn's disease (2009)

The arrival of anti-tumor necrosis factor (TNF) agents has led to a dramatic improvement in the care of patients with Crohn's disease. Since these medications do not work in everyone, and are associated with rare, but serious side effects, we want to selectively treat patients who have the highest chance of responding. A number of variables have been studied to determine their association with response to anti-TNF agents. Clinical parameters include patient characteristics, smoking status and disease phenotype, and biologic markers include C-reactive protein, serum TNF levels and immune responses to microbial antigens. More recently, research has focused on genetics to identify polymorphisms associated with treatment response. Results from individual studies of these factors have not yet allowed for solid clinical applicability. However, further work in this area along with multivariate clinical prediction modeling may soon allow us to deliver 'personalized medicine' by predicting individualized treatment response in patients with Crohn's disease.
Stress-resistance conferred by high level of bcl-2 alpha protein in human B lymphoblastoid cell. (1989)

High levels of human bcl-2 protein(s) result in (i) the tumorigenic conversion of mouse NIH3T3 cells, (ii) the better survival of mouse myeloid cells in the absence of the required growth factor and (iii) give a growth advantage to human EBV-lymphoblastoid B cells both in low serum medium and limiting dilutions. The effect of the high levels of bcl-2 protein in EBV-B cells was further investigated. This revealed that high levels of bcl-2 alpha protein made EBV-B cells more resistant to a variety of stresses including the application of heat shock, ethanol, methotrexate and the absence of serum. Stress resistance was not observed in EBV-B cells with elevated level of c-myc protein. The mechanism of stress resistance conferred by the bcl-2 alpha protein is yet to be determined although the resistance does not seem to be the result of an increase in major heat shock proteins, hsp70 and hsp90, nor the arrest of cells in G1/G0 phase. The increased viability was observed in control transfectants but not in bcl-2 transfectants when cells are seeded at higher density in the absence of serum. Thus the improved survival of cells as a result of high levels of the bcl-2 alpha protein is not specific to the absence of growth factor but is found to occur with a variety of stresses.
Application of neural networks and fuzzy logic to consumer products (2003)

The author describes how neural networks and fuzzy logic have been applied to consumer products. First, the background behind why both technologies have been applied to this field is presented. Second, a brief overview of the fusion technology of neural networks and fuzzy logic is given. As a good example of the R&D process, the application of neural nets to the design and tuning of fuzzy systems is introduced. Applications of the two technologies are classified into five cases: (1) neural networks being used to automate the task of designing and fine tuning the membership functions of fuzzy systems; (2) both fuzzy inference and neural network learning capabilities provided separately; (3) neural networks working as correcting mechanisms for fuzzy systems; (4) neural networks cascaded (serially) with fuzzy systems; and (5) neural networks used to customize the standard system according to each user's preferences and individual needs. Finally, a new trend involving the realization of adaptive systems for the user is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Lens-free microscopy for 3D + time acquisitions of 3D cell culture (2018)

Thanks to a novel three-dimensional imaging platform based on lens-free microscopy, it is possible to perform multi-angle acquisitions and holographic reconstructions of 3D cell cultures directly into the incubator. Being able of reconstructing volumes as large as ~5 mm<sup>3</sup> over a period of time covering several days, allows us to observe a broad range of migration strategies only present in 3D environment, whether it is single cell migration, collective migrations of cells and dispersal of cells. In addition we are able to distinguish new interesting phenomena, e.g. large-scale cell-to-matrix interactions (>1 mm), fusion of cell clusters into large aggregate (~10,000 µm<sup>2</sup>) and conversely, total dissociation of cell clusters into clumps of migrating cells. This work on a novel 3D + time lens-free microscopy technique thus expands the repertoire of phenomena that can be studied within 3D cell cultures.
Local Structure at Mn<SUP>2+</SUP> Ions in Vacuum Annealed Small Cubic ZnS Nanocrystals Self-Assembled Into a Mesoporous Structure (2011)

A mesoporous structure of self-assembled nanocrystals of cubic ZnS doped with Mn2+ ions with a homogeneous distribution of pores of similar size was synthesized at room temperature by a surfactant-assisted liquid-liquid reaction. The component nanocrystals exhibit a high crystallinity and a tight size distribution centered at 2 nm, as well as the narrowest Electron Paramagnetic Resonance (EPR) spectra linewidth and the best resolution reported so-far, effects attributed to self-assembling. The observed EPR spectra consist of lines from the substitutional Mn2+(I) and surface Mn2+(II) and Mn2+(III) centers. Here we show that, in contrast with previous reports, our EPR spectra are highly sensitive to structural changes during pulse annealing in vacuum up to 500 degrees C. The changes are related to the transformation of the surface Mn2+ centers in new Mn2+ centers, attributed to an oxidation process in which the thermal decomposition of the Tween 20 additive, also observed by EPR, seems to be involved. We have also been able to observe, for the first time by EPR spectroscopy, the formation of the ZnO phase and the nanocrystals size increase, which occur during annealing up to 500 degrees C, structural changes confirmed by XRD and TEM observations on the samples previously investigated by EPR.

A Framework for Robot Programming in Cobotic Environments: First user experiments (2018)

The increasing presence of robots in industries has not gone unnoticed. Large industrial players have incorporated them into their production lines, but smaller companies hesitate due to high initial costs and the lack of programming expertise. In this work we introduce a framework that combines two disciplines, Programming by Demonstration and Automated Planning, to allow users without any programming knowledge to program a robot. The user teaches the robot atomic actions together with their semantic meaning and represents them in terms of preconditions and effects. Using these atomic actions the robot can generate action sequences autonomously to reach any goal given by the user. We evaluated the usability of our framework in terms of user experiments with a Baxter Research Robot and showed that it is well-adapted to users without any programming experience.
Statistical Method for Determining and Comparing Limits of Detection of Bioassays (2015)

The current bioassay development literature lacks the use of statistically robust methods for calculating the limit of detection of a given assay. Instead, researchers often employ simple methods that provide a rough estimate of the limit of detection, often without a measure of the confidence in the estimate. This scarcity of robust methods is likely due to a realistic preference for simple and accessible methods and to a lack of such methods that have reduced the concepts of limit of detection theory to practice for the specific application of bioassays. Here, we have developed a method for determining limits of detection for bioassays that is statistically robust and reduced to practice in a clear and accessible manner geared at researchers, not statisticians. This method utilizes a four-parameter logistic curve fit to translate signal intensity to analyte concentration, which is a curve that is commonly employed in quantitative bioassays. This method generates a 95% confidence interval of the limit of detection estimate to provide a measure of uncertainty and a means by which to compare the analytical sensitivities of different assays statistically. We have demonstrated this method using real data from the development of a paper-based influenza assay in our laboratory to illustrate the steps and features of the method. Using this method, assay developers can calculate statistically valid limits of detection and compare these values for different assays to determine when a change to the assay design results in a statistically significant improvement in analytical sensitivity.
Analysis of reading frame and expressional regulation of randomly selected promoter-proximal genes in Escherichia coli (2005)

The expression of seventy-seven randomly cloned genes of Escherichia coli was examined following a variety of treatments including heat shock, glucose starvation, phosphate starvation, ammonium starvation or osmotic shock, with the aid of lacZ reporter gene protein fusions on multicopy plasmids. Two of 77 genes (amr and yigL) had not previously been identified as protein encoding open-reading frames (ORFs) in annotations of the E. coli genome database. Thirteen genes exhibited significant changes in expression in response to at least one of the treatments, and six of them appeared to be controlled by more than one sigma (sigma) factor of RNA polymerase. This study thus allows us not only to identify the reading frame of the genomic genes but also to support the hypothesis earlier proposed that a significant proportion of genes in E. coli are involved in adaptations to various stresses to which the organism is likely to be exposed in the environment.
A Three-Point Directional Search Block Matching Algorithm (2017)

<p>This paper proposes compact directional asymmetric search patterns, which we have named as three-point directional search (TDS). In most fast search motion estimation algorithms, a symmetric search pattern is usually set at the minimum block distortion point at each step of the search. The design of the symmetrical pattern in these algorithms relies primarily on the assumption that the direction of convergence is equally alike in each direction with respect to the search center. Therefore, the monotonic property of real-world video sequences is not properly used by these algorithms. The strategy of TDS is to keep searching for the minimum block distortion point in the most probable directions, unlike the previous fast search motion estimation algorithms where all the directions are checked. Therefore, the proposed method significantly reduces the number of search points for locating a motion vector. Compared to conventional fast algorithms, the proposed method has the fastest search speed and most satisfactory PSNR values for all test sequences.</p>
Analysis Of Capillary Coating Die Flow In An Optical Fiber Coating Applicator (2011)

Viscous heating becomes significant in the high speed resin coating process of glass fibers for optical fiber manufacturing. This study focuses on the coating resin flows inside the capillary coating die of optical fiber coating applicator and they are numerically simulated to examine the effects of viscous heating and subsequent temperature increase in coating resin. Resin flows are driven by fast moving glass fiber and the pressurization at the coating die inlet, while the temperature dependent viscosity of liquid coating resin plays an important role in the resin flow. It is found that the severe viscous heating near the coating die wall profoundly alters the radial velocity profiles and that the increase of final coating thickness by die pressurization is amplified if viscous heating is present.
