Optimized Implementation of a Feature Detector for Embedded Systems Based on the Accelerated Segment Test (2014)

Recent developments made portable embedded systems cheaper, even smaller, and also enormously increased their computing power. But performance in a system itself cannot only be gained by using faster and better hardware or simply utilizing multiple general purpose processor cores, it can also be enhanced by adaption for special auxiliary hardware and optimization of time-critical software parts. Especially when large amounts of data have to be processed, as in image processing algorithms, the benefits of parallel data processing can exceed the additional optimization effort. This thesis will show how to take advantage of the additional processing power of the TI DM3730 processor in the use case of a feature detector based on the Accelerated Segment Test. Two ways of unburdening the CPU by using either SIMD extensions on the CPU itself or by transferring the task to the on-chip DSP were implemented and validated. The evaluation of several ideas and possibilities for optimizations led to the final implementations that reduced processing times by more than 25% on both units.
A centromere-based linkage group on the long arm of human chromosome 17 (1988)

A genetic linkage group on the long arm of chromosome 17 is reported. A maximum likelihood of theta = 0.20 between the centromere-based locus D17Z1 and COL1A1 has been found, as well as a theta = 0.10 between COL1A1 and GH1. The most likely order of the three loci is D17Z1-COL1A1-GH1.
Morphological stabilization of the glycocalyces of 23 strains of five <i>Bacteroides</i> species using specific antisera (1984)

Cells of five Bacteroides species were examined following treatment with homologous antisera and staining with ruthenium red. They were enveloped by glycocalyces and these extensive fibrous exopolysaccharide matrices were fully retained as an integral "capsule" by some cells, while other cells showed "capsule" as well as detached glycocalyx components forming an intercellular "slime.". These extensive glycocalyces collapsed during dehydration for electron microscopy and formed electron-dense accretions on cell surfaces and electron-dense reticula in intercellular spaces when the cells were treated with heterologous antiserum or when antibody stabilization was omitted. The glycocalyces of all strains, both stabilized and unstabilized, were observed outside the outer membranes of cell walls that showed the "classic" gram-negative structural organization. Appropriate modifications of the indirect fluorescent antibody test demonstrated an integral "capsule" on all strains examined; detached glycocalyx and varying amounts of slime were demonstrated after stabilization with homologous, but not heterologous, antiserum.
Induction of β‐methylcrotonyl‐coenzyme A carboxylase in higher plant cells during carbohydrate starvation: evidence for a role of MCCase in leucine catabolism (1996)

Induction of beta-methylcrotonyl-coenzyme A carboxylase (MCCase) activity was observed during carbohydrate starvation in sycamore cells. In mitochondria isolated from starved cells, we noticed a marked accumulation of the biotinylated subunit of MCCase, of which the apparent molecular weight of 74000 was similar to that of the polypeptide from mitochondria of potato tubers. Our results provide evidence for a role of MCCase in the catabolic pathway of leucine, a branched-chain amino acid which transiently accumulates in carbon-starved cells in relation to a massive breakdown of proteins. Furthermore, when control sycamore cells were incubated in the presence of exogenous leucine, this amino acid accumulated in the cells and no induction or accumulation of MCCase was observed, indicating that leucine is not responsible for the induction of its catabolic machinery. Finally, MCCase is proposed as a new biochemical marker of the autophagic process triggered by carbohydrate starvation.
Empowering Multi-Cohort Gene Expression Analysis to Increase Reproducibility (2016)

A major contributor to the scientific reproducibility crisis has been that the results from homogeneous, single-center studies do not generalize to heterogeneous, real world populations. Multi-cohort gene expression analysis has helped to increase reproducibility by aggregating data from diverse populations into a single analysis. To make the multi-cohort analysis process more feasible, we have assembled an analysis pipeline which implements rigorously studied meta-analysis best practices. We have compiled and made publicly available the results of our own multi-cohort gene expression analysis of 103 diseases, spanning 615 studies and 36,915 samples, through a novel and interactive web application. As a result, we have made both the process of and the results from multi-cohort gene expression analysis more approachable for non-technical users.
New Directions in Drug Development: Mixtures, Analogues, and Modeling (1993)

Success in modern medical research is achieved when basic and clinical information about a given disorder converges, either intentionally or fortuitously, with the availability of technology or other means to design and apply interventions for the disorder in question. A prime example is the discovery of insulin and its replacement in patients with IDDM in 1923. Seven decades later, the focus of diabetes management is on improvement in metabolic control to forestall the chronic complications of the disease and improve the quality of life of patients with the disease. Metabolic control is being addressed through the development of insulin analogues using sophisticated techniques to understand the chemistry of insulin and to modify it using rDNA technology. The objective of these efforts is to simulate normal insulin secretion with subcutaneously injected agonists. Quality-of-life needs are being addressed with delivery devices, insulin mixtures, and insulin analogues. Although none of these improvements parallel the discovery of insulin, they do provide an optimistic outlook for patients with diabetes mellitus.
Generalized Argyria after Habitual Use of AgNO<sub>3</sub> (1994)

Generalized argyria, the systemic dissemination and tissue deposition of silver-containing particles, is characterized by slate gray discoloration of skin, most pronounced in sun exposed areas. A 33-year-old woman visited our dermatologic clinic complaining of frequent oral ulceration for 10 years and generalized discoloration of her skin for 5 years. She had had her tongue painted with silver nitrate repeatedly 6 years ago for the treatment of oral ulcers. Physical examination showed slate gray discoloration of her skin, most pronounced on the face and neck. The oral mucosa, tongue, sclera, and conjunctiva also had a slightly blue-gray discoloration. Biopsy specimens from the oral mucosa and forearm revealed small brown-black granules scattered in the dermis and basal lamina of eccrine sweat glands, blood vessels, and hair follicles under the light microscope. Tiny black granules were most numerous in the basal laminae of vessels in electron microscopic observation. Energy dispersive X-ray microanalysis (EDXA) confirmed that many of the granules contained silver.
Stability of ITO Thin Film on Flexible Substrate Under Thermal Aging and Thermal Cycling Conditions (2012)

Indium-tin-oxide (ITO) is a transparent conductive thin film that is widely used as a top conducive layer in photovoltaic solar cells. However, ITO is sensitive to environmental conditions and the electrical conductivity degrades as a consequence of harsh environmental conditions. Furthermore, the thermal expansion coefficient mismatch between the ITO film and the substrate creates stress/strain on the film when the package is subjected to fluctuating temperatures. This could create micro-cracks and consequently damage the film. Therefore, this study was designed to study the effect of the thermal cycling and thermal aging on the ITO thin films to simulate the effect of continuous high temperatures and fluctuating temperatures that may be applied on the thin films during the usage. In this study, two sets of experiments were conducted on a 60Ω/□square sputter-deposited ITO on 127 μm heat stabilized Poly Ethylene Terephthalate (PET) substrate. The first set of experiments contained four samples which were thermally aged at 100 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C for 30 days and the other set of experiments contained another four samples which were thermally cycled for 900 cycles. The thermal profile consisted of a high temperature of 100 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C, a low temperature of 0 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C, dwell time of 10 minutes, and ramp rate of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">°</sup> C/min , as depicted in Fig. 1. The initial results showed that the ITO thin film is not stable in the thermal aging experiment and the electrical resistivity gradually increased for all samples until the end of the 30 days. The degradation happened during the thermal cycling as well. However, SEM images show that the morphology of the ITO surface is stable under both conditions. Energy-dispersive X-ray (EDX) spectroscopy analysis showed stability in the ITO thin film in terms of composition. XRD spectra confirmed the improved crystallinity for the thermally aged films, which corresponded to the increased transmission in the visible region.
T cells from lymphoepithelial thymoma produce a biochemical variant of IL-2. (1985)

The supernatant of TE+ lymphocytes isolated by density gradient from a lympho-epithelial thymoma contained a biochemical variant of T cell growth factor (IL-2). This protein showed two peaks with an apparent molecular weight of 18 and 28 kd by Sephadex G 100 chromatography. Further purification was achieved by DEAE Sephacel and CM Sepharose ion-exchange chromatography. By isoelectric focusing the isoelectric point was found to differ from that of normal. IL-2. Based on these results, the IL-2 variant appears to be a new kind of lymphokine distinguishable from normal IL-2 and similar to a TCGF (L-TCGF peak II) purified from the malignant T cell clone HUT 102.
The GATA-E box-GATA motif in the EKLF promoter is required for in vivo expression (2000)

The erythroid Krüppel-like factor (EKLF) is a key regulatory protein in globin gene expression. This zinc finger transcription factor is required for expression of the adult beta globin gene, and it has been suggested that it plays an important role in the developmental switch from fetal gamma to adult beta globin gene expression. We have previously described a sequence element in the distal promoter region of the mouse EKLF gene that is critical for the expression of this transcription factor. The element consists of an E box motif flanked by 2 GATA-1 binding sites. Here we demonstrate that mutation of the E box or the GATA-1 consensus sequences eliminates expression from the EKLF promoter in transgenic mice. These results confirm the importance of this activator element for in vivo expression of the EKLF gene. (Blood. 2000;95:1652-1655)
Production of isopropanol, butanol and ethanol by metabolic engineered Clostridia (2012)

Au cours des dernières décennies, la fermentation IBE (isopropanol, butanol and éthanol) a connu un regain d'intérêt en vue de la production de carburants ou de composés chimiques à partir de matériaux renouvelables. Dans cette étude, nous avons étudié la production d'IBE avec le producteur naturel Clostridium beijerinckii NRRL B593 et avec des souches modifiées de Clostridium. acetobutylicum ATCC 824. En culture discontinue, la souche C. beijerinckii NRRL B593 excrétait 13.2 g/L d'IBE (dont 4,5 g/L d'isopropanol). Afin d'améliorer la production d'IBE, le gène codant pour l'alcool déshydrogénase secondaire (s-Adh) de NRRL B593, ainsi que différentes combinaisons des gènes des enzymes actives de la conversion de l'acétoacétyl-CoA en acétone, c.-à-d. l'acétoacétyl-CoA acétate/butyrate transférase (ctfA et ctfB) et l'acétoacétate décarboxylase (adc), ont été exprimées dans la souche productrice d'ABE (acétone, butanol éthanol), C. acetobutylicum ATCC 824. Les résultats montrent que la sur-expression des gènes ctfA et ctfB augmentait significativement la productivité et les concentrations finales en IBE tandis que la surexpression du gène adc n'avait qu'un effet limité. Cultivée en discontinu, la meilleure souche, exprimant les gènes adh, ctfA, ctfB et adc a produit 24.4 g/L d'IBE dont 8.8 g/L d'isopropanol avec une productivité de 0.7 g/L h. Cultivée en mode continu à un taux de dilution de 0.1 h-1, la productivité en IBE a été portée à 1.7 g/L h. Puisque le mélange IBE est considéré comme un additif carburant de qualité, les transformants obtenus constituent une avancée réelle vers le développement d'un procédé IBE industriel de production de biocarburants.
Relationship between Biomarkers of Cigarette Smoke Exposure and Biomarkers of Inflammation, Oxidative Stress, and Platelet Activation in Adult Cigarette Smokers (2011)

Meteorological Grading Indexes of Water�saving Irrigation for Corn (2013)

To optimize irrigation and provide a technical guide on agricultural production, the water-saving irrigation meteorological grading indexes of different development stages of maize were built in this paper, based on the principle of farmland water balance, the theories of insufficient irrigation and regulated deficit irrigation, and by using multidimensional information including day-by-day meteorological data in 1961 -2008 from 500 meteorological stations, soil moisture data in ten-day periods in 1993-2008 from 239 agro-meteorological stations (of which, the data in 1980-2008 came from 68 agro-meteorological stations)irrigation amount and yield data were collected to analyze the relationship between the moisture deficiency rates, the quantity of water deficit and yield reduction rates at sowing-jointing stage, jointing-heading stage, heading-mature stage and the whole growth stage of maize referring to the product-water function (FAO-1979). Results indicated that water-saving irrigation meteorological grading indexes from - levels of moisture deficiency rate and the quantity of water deficit (secondary indicators) were [10%, 25%), [25%, 40%) and 40%, corresponding to 1 -2 irrigations (600m 3 hm -2 each time), 2-3 irrigations and >3 irrigations for the whole growth stage of maize, respectively. For sowing-jointing stage, the indicators were [15%, 30%), [30%, 45%) and 45%, corresponding to 0.5 irrigation, 1 irrigations and 1 irrigation, respectively. For jointing-heading stage, the indicators were [15%,30%), [30%, 45%) and 45%, corresponding to 0.5 irrigation, 1 irrigation and 1 irrigation, respectively. For heading-mature stage, the indicators were [15%, 30%), [30%, 50%) and 50%, corresponding to 1 irrigation, 1 -2 irrigations and 2 irrigations, respectively. These indices could supply scientific support for the optimization of irrigationand give guidance to agricultural production.

Transient subpicosecond Raman studies of electron velocity overshoot in an InP <i>p</i>-<i>i</i>-<i>n</i> nanostructure semiconductor (1996)

Transient electron transport in an InP p-i-n nanostructure semiconductor has been studied by subpicosecond Raman spectroscopy at T=300 K. Both the nonequilibrium electron distribution and electron drift velocity in the regime of electron velocity overshoot have been directly measured. It is demonstrated that electron drift velocity in an InP p-i-n nanostructure is significantly larger than that in a GaAs p-i-n nanostructure sample, as a result of the larger central to satellite valley energy separation in InP.

Genetic and linguistic differentiation in the Americas. (1993)

The relationship between linguistic differentiation and evolutionary affinities was evaluated in three tribes of the Pacific Northwest. Two tribes (Nuu-Chah-Nulth and Bella Coola) speak Amerind languages, while the language of the third (Haida) belongs to a different linguistic phylum--Na-Dene. Construction of a molecular phylogeny gave no evidence of clustering by linguistic affiliation, suggesting a relatively recent ancestry of these linguistically divergent populations. When the evolutionary affinities of the tribes were evaluated in terms of mitochondrial sequence diversity, the Na-Dene-speaking Haida had a reduced amount of diversity compared to the two Amerind tribes and thus appear to be a biologically younger population. Further, since the sequence diversity between the two Amerind-speaking tribes is comparable to the diversity between the Amerind tribes and the Na-Dene Haida, the evolutionary divergence within the Amerind linguistic phylum may be as great as the evolutionary divergence between the Amerind and Na-Dene phyla. Hence, in the New World, rates of linguistic differentiation appear to be markedly faster than rates of biological differentiation, with little congruence between linguistic hierarchy and the pattern of evolutionary relationships.
Long-term safety and analgesic efficacy of buprenorphine buccal film in patients with moderate-to-severe chronic pain requiring around-the-clock opioids (2017)

Sidelobe Modulation Scrambling Transmitter Using Fourier Rotman Lens (2013)

A means for scrambling the digital modulation content in the sidelobes of a radio transmission from a steerable antenna array is presented. The method uses a Fourier transform beam-forming network simultaneously excited by an RF information stream and orthogonally injected interference streams. The proposed system is implemented using a Fourier Rotman lens and its operational characteristics are validated for a 10 GHz QPSK transmission.

Chaotic scattering with localized losses: <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>S</mml:mi></mml:math>-matrix zeros and reflection time difference for systems with broken time-reversal invariance (2020)

Motivated by recent studies of the phenomenon of coherent perfect absorption, we develop the random matrix theory framework for understanding statistics of the zeros of the (subunitary) scattering matrices in the complex energy plane, as well as of the recently introduced reflection time difference (RTD). The latter plays the same role for S-matrix zeros as the Wigner time delay does for its poles. For systems with broken time-reversal invariance, we derive the n-point correlation functions of the zeros in a closed determinantal form, and we study various asymptotics and special cases of the associated kernel. The time-correlation function of the RTD is then evaluated and compared with numerical simulations. This allows us to identify a cubic tail in the distribution of RTD, which we conjecture to be a superuniversal characteristic valid for all symmetry classes. We also discuss two methods for possible extraction of S-matrix zeros from scattering data by harmonic inversion.

Radio-frequency Density-independent Moisture Determination in Wheat (1993)

A technique to rapidly determine the moisture content of hard red winter wheat, Triticum aestivum L., independent of density, is presented. The complex impedance of bulk samples at 1 and 10 MHz was used along with a density-independent function to predict moistures ranging from approximately 11 to 22% in samples with bulk densities ranging from 0.65 to 0.85 g/cm3. Calibration was performed on wheat of two cultivars harvested in 1991, and verification was tested on a different cultivar harvested in 1990. Measurements of the system were compared to air-oven moisture determinations with a standard deviation of the differences of 0.5% moisture content.
