Photoacoustic determination of small optical absorption coefficients: extended theory (1979)

Photoacoustic measurement of small absorption coefficients provides an important alternative to standard techniques. The theoretical basis for such measurements is extended to include the effects of thermally generated mechanical motion of the sample, by incorporating the thermoelastic equations for an isotropicm solid in a cylindrical configuration. Sample calculations show that this thermoacoustic effect may dominate the photoacoustic signal for certain modulation frequencies and beam configurations.
Fault location using wavelet packets (2003)

A technique using wavelet packets is presented for accurate fault location on power lines with branches. It relies on detecting fault-generated transient traveling waves and identifies some waves reflected back from discontinuities and the fault point. Wavelet packets analysis is used to decompose and reconstruct high-frequency fault signals. An eigenvector matrix consists of local energies of high-frequency content of the fault signal; the faulty section is determined by comparing local energies in the eigenvector matrix with a given threshold. With the faulty section determined, the time ranges of two reflected waves related with fault point would be found out, then the fault point is located. The paper shows the theoretical development of the algorithm, and together with the results obtained using EMTP simulation software modeling, a simple 10 kV overhead line circuit.

Production and properties of beta-mannanase by free and immobilized cells of Aspergillus oryzae NRRL 3488. (2001)

Seven fungi were tested for production of mannanases. The highest mannanase activities were produced by Aspergillus oryzae NRRL 3488 after 7 days in static cultures. Mannanases were induced by gum locust bean (1.0%). The highest mannanase activity was produced when a mixture of peptone, urea and ammonium sulphate was used as nitrogen source. Zn2+ or Co2+ favoured enzyme production. The immobilized cells on Ca-alginate and agar were able to produce beta-mannanase for four runs with a slight decrease in the activity. The optimum temperature for enzyme reaction was 50-55 degrees C at pH 6.0. In the absence of substrate the enzyme was thermostable retaining 75% activity for 1 h at 50 degrees C, and 68% activity for 1 h at 60 degrees C.

Capillary-Pressure Curves for Low-Permeability Chalk Obtained by Nuclear Magnetic Resonance Imaging of Core-Saturation Profiles (1999)

Summary A new technique for obtaining water-oil capillary pressure curves, based on nuclear magnetic resonance (NMR) imaging of the saturation distribution in flooded cores is presented. In this technique, a steady-state fluid saturation profile is developed by flooding the core at a constant flow rate. At the steady-state situation where the saturation distribution no longer changes, the local pressure difference between the wetting and nonwetting phases represents the capillary pressure. The saturation profile is measured using an NMR technique and for a drainage case, the pressure in the nonwetting phase is calculated numerically. This paper presents the NMR technique and the procedure for calculating the pressure distribution in the sample. Inhomogeneous samples produce irregular saturation profiles, which may be interpreted in terms of variation in permeability, porosity, and capillary pressure. Capillary pressure curves for North Sea chalk obtained by the new technique show good agreement with capillary pressure curves obtained by traditional techniques.
Real-time Risk Assessment Framework for Unmanned Aircraft System (UAS) Traffic Management (UTM) (2017)

The new Federal Aviation Administration (FAA) Small Unmanned Aircraft rule (Part 107) marks the first national regulations for commercial operation of small unmanned aircraft systems (sUAS) under 55 pounds within the National Airspace System (NAS). Although sUAS flights may not be performed beyond visual line-of-sight or over non- participant structures and people, safety of sUAS operations must still be maintained and tracked at all times. Moreover, future safety-critical operation of sUAS (e.g., for package delivery) are already being conceived and tested. NASA's Unmanned Aircraft System Trac Management (UTM) concept aims to facilitate the safe use of low-altitude airspace for sUAS operations. This paper introduces the UTM Risk Assessment Framework (URAF) which was developed to provide real-time safety evaluation and tracking capability within the UTM concept. The URAF uses Bayesian Belief Networks (BBNs) to propagate off -nominal condition probabilities based on real-time component failure indicators. This information is then used to assess the risk to people on the ground by calculating the potential impact area and the effects of the impact. The visual representation of the expected area of impact and the nominal risk level can assist operators and controllers with dynamic trajectory planning and execution. The URAF was applied to a case study to illustrate the concept.
Thermal conductivity and electrical properties of 6<i>H</i> silicon carbide (1979)

Thermal conductivity measurements of 6H SiC crystals were done in the 300–500 K range by means of radiation thermometry. Both p- and n-type crystals with carrier concentrations in the 8×1015 to 1020 cm−3 range were used. For the purest samples it was found that the thermal conductivity normal to the c axis is proportional to T−1.49, the room-temperature value being 3.87 W/cm deg. It was also found that the thermal conductivity parallel to the c axis is about 30% lower than that normal to the c axis. Electrical data in the 100–1000 K range are also presented.
Breakpoint mapping by next generation sequencing reveals causative gene disruption in patients carrying apparently balanced chromosome rearrangements with intellectual deficiency and/or congenital malformations (2013)

NGS is a powerful tool allowing rapid breakpoint cloning of ABCR at the molecular level. We showed that in three out of four patients, gene disruption could account for the phenotype, allowing adapted genetic counselling and stopping unnecessary investigations. We propose that patients carrying ABCR with an abnormal phenotype should be explored systematically by NGS once a genomic imbalance has been excluded by array CGH.

Optimal Water Coverage on Alumina: A Key to Generate Lewis Acid–Base Pairs that are Reactive Towards the CH Bond Activation of Methane (2011)

Die niedrige OH-Bedeckung von bei 700 °C vorbehandeltem γ-Aluminiumoxid führt zu metastabilen, dreifach koordinierten AlIII-Zentren und reaktiven (AlIII,O)-Lewis-Säure-Base-Paaren. Wasser spielt bei diesem Prozess eine doppelte Rolle, indem es die Basizität der Sauerstoffatome erhöht, ohne die Lewis-Acidität der AlIII-Zentren zu beeinträchtigen, und außerdem die metastabile (110)-Oberflächenschicht, die diese Zentren enthält, stabilisiert.
Natural Antisense Transcripts (2005)

The sequencing of whole genomes and the subsequent annotation of cDNAs revealed that about 20% of human and mouse genes overlap resulting in potential pairs of sense and antisense transcripts. An increasing number of experimentally identified antisense transcripts concur with this predication. Characterization of overlapping transcripts in various species indicates that this form of RNA-mediated gene regulation represents a widespread phenomenon. However, the physiological relevance of natural antisense transcripts remains obscure. Genomic studies suggest that duplex formation between sense and antisense is required for biological function. Antisense transcripts play an established role in imprinting and X-chromosome inactivation and genomic rearrangements as observed in B and T leukocytes. Only a relatively small percentage of the predicted antisense transcripts are related to these biological phenomena that are also related to mono-allelic expression. Consequently, there are at least two categories of natural antisense transcripts that show significant differences with regard to their biological function as well as the potential mechanisms involved.
Purinoceptors: Ontogeny and phylogeny (1996)

The majority of studies of the functional distribution of purinoceptors have been carried out with mammalian preparations. The objective of this article is to review the disparate literature describing purinoceptor-mediated effects in invertebrates and lower vertebrates and, in view of the concept that ontogeny repeats phylogeny, to review also the evidence for purinoceptor involvement in the complex signaling involved in embryonic development. Even with the limited information currently available, it is clear that purinoceptors are involved in early signalling in vertebrate embryos; one novel G protein-coupled P2Y receptor has already been cloned and characterized in frog embryo and hopefully more will follow. It is also clear that purinoceptors for both adenosine and ATP are present in early evolution and play a number of different roles in most, if not all, invertebrate and lower species. However, until selective agonists and antagonists are identified for the recently cloned purinoceptors subtypes in vertebrates, it will not be possible to resolve questions concerned with the evolution of these subtypes. Molecular cloning of genes encoding receptors for purines and pyrimidines from invertebrates and lower vertebrates represents an alternative approach to advancing knowledge in the area. Drug Dev.

Real-Time Screen-Camera Communication Behind Any Scene (2015)

We present HiLight, a new form of real-time screen-camera communication without showing any coded images (e.g., barcodes) for off-the-shelf smart devices. HiLight encodes data into pixel translucency change atop any screen content, so that camera-equipped devices can fetch the data by turning their cameras to the screen. HiLight leverages the alpha channel, a well-known concept in computer graphics, to encode bits into the pixel translucency change. By removing the need to directly modify pixel RGB values, HiLight overcomes the key bottleneck of existing designs and enables real-time unobtrusive communication while supporting any screen content. We build a HiLight prototype using off-the-shelf smart devices and demonstrate its efficacy and robustness in practical settings. By offering an unobtrusive, flexible, and lightweight communication channel between screens and cameras, HiLight opens up opportunities for new HCI and context-aware applications, e.g., smart glasses communicating with screens to realize augmented reality.
Intelligent mapping of hyperspace (2004)

We address some particular issues related to the difficult task of automatically structuring information available in illstructured environments, through a distributed hypermedia system like the Web. We present an original approach to this problem, which coordinates different aspects of automatic computation of relations between nodes in hyperspace, through dynamic linking, using intelligent mapping of the domain material, by the application of spatial reasoning. We present a multipurpose framework to dynamically structure information in the Web and a proof-of-concept prototype, dubbed hypermap, implemented to build the spatial cognitive maps of the hyperspace, inspired by the human cognitive mapping process.
DNA sequencing in HydroLink matrices: Extension of reading ability to > 600 nucleotides (1990)

All the systems for optimizing DNA sequencing published so far have introduced modifications regarding: (i) linearization of band migration via ionic strength gradients or wedge-shaped gels; (ii) automatization of band reading via introduction of fluorescent probes; (iii) direct blotting analysis; (iv) pulsed electric fields and (v) discontinuous buffer systems. In all these systems, DNA sequence reading with an accuracy of ca. 98% rarely exceeds a length of 350 bases. We have chosen, in order to increase the reading ability of a single gel, to manipulate the characteristics of the gel matrix. The Seq-HydroLink gel formation here reported allows optimal reading, from a single gel run, of at least 600 bases. In order to guarantee this reading ability in a single run, the upper and lower ends of the ladder are time-resolved, i.e. the same sample is applied to the gel matrix at three different time intervals. The present system represents an increase of at least 30% in reading ability as compared with any type of polyacrylamide gel formulation so far reported.
Establishing Primary Adult Fibroblast Cultures From Rodents (2010)

The importance of using primary cells, rather than cancer cell lines, for biological studies is becoming widely recognized. Primary cells are preferred in studies of cell cycle control, apoptosis, and DNA repair, as cancer cells carry mutations in genes involved in these processes. Primary cells cannot be cultured indefinitely due to the onset of replicative senescence or aneuploidization. Hence, new cultures need to be established regularly. The procedure for isolation of rodent embryonic fibroblasts is well established, but isolating adult fibroblast cultures often presents a challenge. Adult rodent fibroblasts isolated from mouse models of human disease may be a preferred control when comparing them to fibroblasts from human patients. Furthermore, adult fibroblasts are the only available material when working with wild rodents where pregnant females cannot be easily obtained. Here we provide a protocol for isolation and culture of adult fibroblasts from rodent skin and lungs. We used this procedure successfully to isolate fibroblasts from over twenty rodent species from laboratory mice and rats to wild rodents such as beaver, porcupine, and squirrel.
<title>Infrared Photography As A Diagnostic Tool For The Burn Wound</title> (1974)

The classification of burns is an area of considerable confusion (Ref. 1,2). The popu-lar description of first, second, and third degree was originated over 150 years ago by Boyer. This classification was based on superficial appearance and was used almost exclusively with minor modifications until about 30 years ago. Burn physicians then began to realize that the depth of injury was of prime importance, and not this superficial appearance. Thus, there evolved a two-category description which is defined as follows: The partial-thickness burn is a wound in which sufficient epithelial elements remain to allow spontaneous skin repair, and the full-thickness burn is a wound in which the epithelial elements necessary for spontaneous skin repair have been destroyed. In the latter case, skin repair can occur by contraction of the wound and cell migration from the edge. When this peripheral regrowth is not possible or adequate, grafting is necessary.
Laser refractometer as a transfer standard of the pascal (2016)

We have developed a new low pressure sensor which is based on the measurement of (nitrogen) gas refractivity inside a Fabry-Perot (FP) cavity. We compare pressure determinations via this laser refractometer to that of well-established ultrasonic manometers throughout the range 100Pa to 100000Pa. The refractometer demonstrates 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-6</sup> precision for p > 50 kPa; - as good or better than the manometer - we argue that a laser refractometer represents a state-of-the-art transfer standard of the pascal. We also claim the refractometer has an accuracy of U(p <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">FP</sub> ) = [(16mPa) <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> + (11.9 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-6</sup> · p) <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ] <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1/2</sup> , as realized through the properties of nitrogen gas.
New DEFT sequences for the acquisition of one‐dimensional carbon NMR spectra of small unlabelled molecules (2006)

The acquisition time and quality of 1D 13C{1H} spectra can be improved substantially by using a modified driven equilibrium Fourier transform (DEFT) sequence, which is specifically designed to compensate for the effects of B1 inhomogeneity, pulse miscalibration and frequency offsets. The new sequence, called uniform driven equilibrium Fourier transform (UDEFT), returns the carbon magnetization with a high accuracy along its equilibrium position after each transient is complete. Thus, the sequence allows the use of relaxation delays (RD), which are much shorter than the carbon T1 of the molecule, thereby speeding up the acquisition process of 1D 13C{1H} spectra. To achieve this level of performance, UDEFT employs a refocusing element constituted by a composite adiabatic carbon pulse surrounded by two 90 degrees carbon pulses whose phases are designed to compensate for 90 degrees pulse miscalibrations in an MLEV manner (90 degrees+x-tau(FID)-180+y(Adia)-tau-90 degrees+x-180 degrees+x(Adia)). A version of the UDEFT sequence allows recording 1D 13C{1H} spectra devoid of heteronuclear NOE by using a matched adiabatic 1H decoupling scheme where an even number of 180 degrees adiabatic pulses is applied during the UDEFT module. Spectra of a solution of 300 mM camphor that contains some carbon nuclei with very long T1 relaxation times (90 s and 78 s) were acquired with 128 scans in 10 min using a 5 s relaxation delay.
Suppression of invasion of a hamster pancreatic cancer cell line by antisense oligonucleotides mutation-matched to K-ras gene. (2005)

The anti-invasive activity of antisense oligonucleotides (ASO) specific to the K-ras gene in hamster pancreatic cancer was investigated. HaP-T1, a cell culture derived from BHP-induced hamster pancreatic cancer, was used. After liposome-mediated transfection with mutation-matched and mutation-mismatched ASO in different concentrations, cell proliferation was studied by MTT and MTT-agarose methods. In vitro chemoinvasion assay with the reconstitution of a matrix of a basement membrane onto a filter in a Boyden chamber was performed. Mutation-matched ASO inhibited the tumor growth and invasiveness of HaP-T1 in a dose-dependent manner, while mutation-mismatched ASO were not effective in inhibiting invasion. The present study suggests that antisense oligonucleotides mutation-matched to the K-ras gene may be a new anticancer strategy for pancreatic cancer since they inhibited not only tumor growth but also invasiveness in vitro.
