Matching of stereo image pairs for industrial vision systems (1989)

A matching technique for stereo images which uses the Fourier transform for disparity estimation in a robot workspace environment is presented. The method consists of three phases. The first is a disparity estimation process which makes use of the shifting property of the Fourier transform. The second is a guided feature matching technique which selects the corners as feature points. The third is a local matching procedure that uses the corner matching results. The final output of the method is a disparity map corresponding to the matched points. The results show that the method produces accurate and dense disparity maps in a robust workspace environment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Autonomous maneuver of a farm vehicle with a trailed implement: motion planner and lateral-longitudinal controllers (2010)

This paper addresses the problem of path generation and motion control for the autonomous maneuver of a farm vehicle with a trailed implement in headland. A reverse turn planner is firstly investigated, based on primitives connected together to easily generate the reference motion. Then, both steering and speed control algorithms are presented to accurately guide the vehicle-trailer system. They are based on a kinematic model extended with additional sliding parameters and on model predictive control approaches. Real world experiments have been carried out on a low friction terrain with an experimental mobile robot pulling a trailer. At the end of each row, the reverse turn is automatically generated to connect the next reference track, and the maneuver is autonomously performed by the vehicle-trailer system. Reported experiments demonstrate the capabilities of the proposed algorithms.

LayoutVAE: Stochastic Scene Layout Generation From a Label Set (2019)

Recently there is an increasing interest in scene generation within the research community. However, models used for generating scene layouts from textual description largely ignore plausible visual variations within the structure dictated by the text. We propose LayoutVAE, a variational autoencoder based framework for generating stochastic scene layouts. LayoutVAE is a versatile modeling framework that allows for generating full image layouts given a label set, or per label layouts for an existing image given a new label. In addition, it is also capable of detecting unusual layouts, potentially providing a way to evaluate layout generation problem. Extensive experiments on MNIST-Layouts and challenging COCO 2017 Panoptic dataset verifies the effectiveness of our proposed framework.
Selective dry etching of oxide films for spacer applications in a high density plasma (1996)

The use of a high density plasma to etch oxide side wall spacers was investigated. Process trends and the optimum process conditions required were determined. Oxide and polysilicon etch rates, uniformities, and the selectivity of oxide to polysilicon were all measured. The resulting etch chemistry had an oxide etch rate of 350 nm/min with a selectivity of oxide to polysilicon of 30:1.
Interferon-<i>α</i>Primed Tumor-Infiltrating Lymphocytes Combined with Interleukin-2 and Interferon-<i>α</i>as Therapy for Metastatic Renal Cell Carcinoma (1993)

Murine models demonstrate therapeutic synergy for the combination of interleukin-2, interferon-alpha and tumor-infiltrating lymphocytes. We treated 11 patients with metastatic renal cell carcinoma with a novel regimen consisting of in vivo primed tumor-infiltrating lymphocytes, interferon-alpha and interleukin-2. Patients received interferon-alpha before radical nephrectomy; in vivo primed tumor-infiltrating lymphocytes were isolated and expanded in vitro. Low dose continuous infusion interleukin-2 at a dose of 2 x 10(6) units per m.2 per day was administered for 96 hours during each treatment week and interferon-alpha was administered as a subcutaneous injection at a dose of 6 x 10(6) units per m.2 per day on days 1 and 4 of the interleukin-2 infusion. No therapy was given during the last 3 days of a treatment week. One course of therapy consisted of 3 weeks of therapy followed by 3 weeks of rest. Patients were treated until maximal response, disease progression or dose limiting toxicity. A maximum of 6 courses of therapy were administered. Eleven patients underwent interferon-alpha priming and subsequent radical nephrectomy. In vivo primed tumor-infiltrating lymphocytes were successfully expanded in all 11 patients with an expansion index of greater than 170. In vivo primed tumor-infiltrating lymphocytes maintained their lytic activity for greater than 5 to 8 weeks in culture as demonstrated in the 4-hour 51chromium release assay. Ten patients underwent multimodality biological therapy and 3 (30%, 95% confidence interval 6 to 65%) have achieved complete response (2 clinical and 1 surgical) with durations of 24+, 23+ and 5+ months. Patients with stable disease received no additional therapy. No deaths and no grade 4 toxicities occurred. Immunotherapy using a combination of interferon-alpha primed tumor-infiltrating lymphocytes, low dose continuous infusion interleukin-2 and interferon-alpha can induce significant and durable antitumor responses in some patients with advanced renal cell carcinoma.
Comparing greenhouse sprayers: the dose‐transfer process (2003)

Three sprayers were evaluated for their affect on retention and efficacy: a carbon dioxide powered high-volume sprayer, a DRAMM coldfogger, and an Electrostatic Spraying Systems (ESS) sprayer with air-assistance. The active ingredients used were spinosad and azadirachtin. The plant canopy was constructed in the greenhouse using potted soybeans (Glycine max (L) Merrill cr Pioneer 9392). Application efficacy with spinosad was assessed using thrips [Western flower thrips, Frankliniella occidentalis (Pergande)] and mite (two-spotted spider mite, Tetranychus urticae Koch) abundance on shoots and leaves. Application efficacy with azadirachtin was assessed using thrips and aphid (soybean aphid, Aphis glycines Matsumura) abundance on shoots and leaves. The atomization characteristics of each sprayer were measured using an Aerometrics phase/Doppler particle analyzer (PDPA) 100-1D. The results of four tests are presented. Two tests used each sprayer according to manufacturer recommendations. These are 'recommended volume' tests that confound differences in toxicant distribution caused by the sprayer with differences caused by changes in application volume. The other two tests were 'constant volume' tests in which all three sprayers were used to deliver the same application volume. Both types of test gave differences between sprayers in retention of toxicant, but only the recommended volume tests showed significant effects of the sprayers on pest abundance. We attribute this difference to the role played by changing application volumes in the dose-transfer process. The constant-volume tests showed that application equipment influences efficacy.

<i>Escherichia coli</i> Ghost Production by Expression of Lysis Gene <i>E</i> and Staphylococcal Nuclease (2003)

The production of bacterial ghosts from Escherichia coli is accomplished by the controlled expression of phage phiX174 lysis gene E and, in contrast to other gram-negative bacterial species, is accompanied by the rare detection of nonlysed, reproductive cells within the ghost preparation. To overcome this problem, the expression of a secondary killing gene was suggested to give rise to the complete genetic inactivation of the bacterial samples. The expression of staphylococcal nuclease A in E. coli resulted in intracellular accumulation of the protein and degradation of the host DNA into fragments shorter than 100 bp. Two expression systems for the nuclease are presented and were combined with the protein E-mediated lysis system. Under optimized conditions for the coexpression of gene E and the staphylococcal nuclease, the concentration of viable cells fell below the lower limit of detection, whereas the rates of ghost formation were not affected. With regard to the absence of reproductive cells from the ghost fractions, the reduction of viability could be determined as being at least 7 to 8 orders of magnitude. The lysis process was characterized by electrophoretic analysis and absolute quantification of the genetic material within the cells and the culture supernatant via real-time PCR. The ongoing degradation of the bacterial nucleic acids resulted in a continuous quantitative clearance of the genetic material associated with the lysing cells until the concentrations fell below the detection limits of either assay. No functional, released genetic units (genes) were detected within the supernatant during the lysis process, including nuclease expression.
A novel approach to efficient inrush current limitation for LED power applications (2014)

The increasing number of cost-efficient power supplies without internal limitation of the inrush current in the field of LED-lighting necessitates inrush current limiting measures within the energy distribution system. Common circuits were analyzed with respect to their functionality, fail-safety and their compliance with regulatory requirements, manufacturing costs and energy efficiency. This paper presents the development and validation of a novel circuitry for inrush current limitation, ideally fulfilling the requirements concerning an increased repetition rate of the protection function, intrinsic thermal safety as well as a cost-effective implementation for a maximum coverage of price-sensitive markets. In contrast to existing solutions this approach results in a far better cost-to-benefit-ratio.
Resonance light scattering particles as ultrasensitive labels for detection of analytes in a wide range of applications (2001)

We have developed a new detection technology that uses resonance light scattering (RLS) particles as labels for analyte detection in a wide range of formats including immuno and DNA probe type of assays in solution, solid phase, cells, and tissues. When a suspension of nano sized gold or silver particles is illuminated with a fine beam of white light, the scattered light has a clear (not cloudy) color that depends on composition and particle size. This scattered light can be used as the signal for ultrasensitive analyte detection. The advantages of gold particles as detection labels are that (a) their light producing power is equivalent to more than 500,000 fluorescein molecules, (b) they can be detected at concentrations as low as 10(-15) M in suspension by eye and a simple illuminator, (c) they do not photobleach, (d) individual particles can be seen in a simple student microscope with dark field illumination, (e) color of scattered light can be changed by changing particle size or composition for multicolor multiplexing, and (f) they can be conjugated with antibodies, DNA probes, ligands, and protein receptors for specific analyte detection. These advantages allow for ultra-sensitive analyte detection with easiness of use and simple and relatively inexpensive instrumentation. We have shown that our RLS technology can indeed be used for ultra-sensitive detection in a wide range of applications including immuno and DNA probe assays in solution and solid phases, detection of cell surface components and in situ hybridization in cells and tissues. Most of the assay formats described in this article can be adapted for drug fast throughput screening.

A 1.2µ BiCMOS realization of a low power and offset-free voltage/frequency converter (1997)

In this article, a voltage/frequency converter with dynamic offset trimming is presented. This converter is simple in structure, good in accuracy and low in power consumption. It is realized in a 1.2µ BiCMOS technology. The result of test shows that an offset reduction as smaller as 600µV can be obtained.
Flow cytometry and bacterial pathogenesis (1998)

Our understanding of microbial adaptations to diverse and threatening environments is limited by the assumption that the behavior of individual bacteria can be accurately determined by measuring the behavior of populations. Recent advances in gene expression reporter systems, fluorescence microscopy and flow cytometry allow microbiologists to explore the complex interactions between bacteria and their environment with single cell resolution. The application of these technologies has been particularly useful in systems, such as host-pathogen interactions, where genetic analysis is often cumbersome. Recently, flow cytometry is increasingly being applied to study host-pathogen interactions.
Algal Blooms in Arkansas Streams, Ponds, and Lakes (2018)

Did you know that algae are a natural part of ponds, lakes, streams, and rivers? These organisms grow in the water (plankton) and on rocks, plants, and other surfaces (periphyton) and sometimes periphyton slough off into the water (seston). Most of the time these algae are hardly noticeable in waterbodies; however, sometimes they can form very noticeable algal blooms.
A comparison of seismic velocity inversion methods for layered acoustics (2009)

In seismic imaging, one tries to infer the medium properties of the subsurface from seismic reflection data. These data are the result of an active source experiment, where an explosive source and an array of receivers are placed at the surface. Because of the absence of low frequencies in the data, the corresponding inverse problem is strongly nonlinear in the slowly varying component of the velocity. The least-squares misfit functional typically exhibits local minima and has a small basin of attraction. The usual approach to fitting the data in a least-squares sense by employing a gradient-based optimization method will therefore most likely result in a wrong velocity model. In the geophysical community, this problem has long been recognized and alternative formulations of the inverse problem have been developed. We review several of these formulations and analyse the sensitivity to the error in the smooth velocity component. This analysis is carried out for laterally homogeneous velocities using an asymptotic solution of the wave equation. The analysis suggests that formulations which are geared towards fitting the phases of the data, rather than the amplitudes, have smooth corresponding misfit functionals with a large basin of attraction.
Rational Design of Cyclic Peptide Inhibitors of U2AF Homology Motif (UHM) Domains To Modulate Pre-mRNA Splicing (2016)

U2AF homology motifs (UHMs) are atypical RNA recognition motif domains that mediate critical protein-protein interactions during the regulation of alternative pre-mRNA splicing and other processes. The recognition of UHM domains by UHM ligand motif (ULM) peptide sequences plays important roles during early steps of spliceosome assembly. Splicing factor 45 kDa (SPF45) is an alternative splicing factor implicated in breast and lung cancers, and splicing regulation of apoptosis-linked pre-mRNAs by SPF45 was shown to depend on interactions between its UHM domain and ULM motifs in constitutive splicing factors. We have developed cyclic peptide inhibitors that target UHM domains. By screening a focused library of linear and cyclic peptides and performing structure-activity relationship analysis, we designed cyclic peptides with 4-fold improved binding affinity for the SPF45 UHM domain compared to native ULM ligands and 270-fold selectivity to discriminate UHM domains from alternative and constitutive splicing factors. These inhibitors are useful tools to modulate and dissect mechanisms of alternative splicing regulation.
Characterization of a surface micromachined pressure sensor array (1995)

A surface micromachined pressure sensor array has been designed and fabricated. The sensors are based upon deformable, silicon nitride diaphragms with polysilicon piezoresistors. Absolute pressure is detected by virtue of reference pressure cavities underneath the diaphragms. For this type of sensor, design tradeoffs must be made among allowable diaphragm deflection, diaphragm size, and desirable pressure ranges. Several fabrication issues were observed and addressed. Offset voltage, sensitivity, and nonlinearity of 100 µm diameter sensors were measured. 1.
Amyloid beta mediates memory formation (2009)

The amyloid precursor protein (APP) undergoes sequential cleavages to generate various polypeptides, including the amyloid beta (1-42) peptide (Abeta[1-42]), which is believed to play a major role in amyloid plaque formation in Alzheimer's disease (AD). Here we provide evidence that, in contrast with its pathological role when accumulated, endogenous Abeta in normal hippocampi mediates learning and memory formation. Furthermore, hippocampal injection of picomolar concentrations of exogenous Abeta(1-42) enhances memory consolidation. Correlative data suggest that Abeta peptides may exert their function via nicotinic acethylcoline receptors. Hence, Abeta peptides, including Abeta(1-42), play an important physiological role in hippocampal memory formation.

Flow-Through Sampling for Electrophoresis-Based Microchips and Their Applications for Protein Analysis (2002)

This work presents a model behind the operation of a flow-through sampling chip and its application for immunoseparation, as well as its integration with a wash/elution bed for protein purification, concentration, and detection. This device used hydrodynamic pressure to drive the sample flow, and a gating voltage was applied to the electrophoretic channel on the microchip to control the sample loading for the separation and to inhibit sample leakage. The deduced model indicates that the critical gating voltage (VC) that is defined as the minimum gating voltage applied to the microchip for sampling is a function of the pump flow rate, the configuration of the microchannel on the chip, and the electroosmosis of the buffer solution. It was found that the theoretical V(C) values calculated from the measured electroosmotic mobilities and flow split ratios were comparable to those experimentally obtained from two microchips with different sampling channel sizes. This had an error percentage ranging from 1 to 20%. Because the hydrodynamic flow is insensitive to electrophoretic mobility, this electrophoresis-based microchip device was free of injection bias due to different ionic strength and electrophoretic mobility in the sample. Additionally, the usefulness of this device was demonstrated for the study of affinity interactions. Mixtures of Cy5-labeled bovine serum albumin (Cy5-BSA) and anti-BSA in various proportions were introduced into the microchip via a syringe pump, and the immunocomplex was electrophoretically separated from the free Cy5-BSA on the microchip. Based on the relative intensity of the free and complex BSA, the binding constant of BSA and anti-BSA was estimated as 3.3 x 10(7) M(-1). Furthermore, a C18 microcartridge (20 microL) was connected to the hydrodynamic inlet of the microchip. Using this device, the wash/elution step can be integrated on-line with the electrophoretic separation and detection on the microchip. Results show that the calibration curve of Cy5-BSA obtained from this integrated device has an R2 value greater than 0.99 and a minimum of quantitation at approximately 10 ng. This direct sampling method is another means of subfractionation, resulting in a relatively greater concentration factor than the average concentration of the whole fraction. Moreover, the electrical field-free bed ensures that the protein interaction will not be affected by the electric field during the wash/elution step.
The effect of truncation reduction in fan beam transmission for attenuation correction of cardiac SPECT (1996)

A limitation of fan beam transmission imaging using a 40 cm field-of-view scintillation camera is the data truncation that occurs when imaging medium to large-sized patients. With filtered backprojection, truncation may cause bright rings in the reconstructed image. The primary objective of this study is to evaluate a method to extrapolate the truncated transmission data under clinically relevant count density conditions. The method involves obtaining the patient contour by processing the scatter and photopeak emission data, filling the contour with the attenuation coefficient for soft tissue, reprojecting the contour image, extrapolating the truncated projection set with the projections. A long focal length (114 cm) fan collimator is used on one head of a triple camera SPECT system to acquire transmission data. The two remaining detectors are equipped with low energy, ultra high resolution parallel hole collimators. A large thorax phantom (38 cm/spl times/26 cm) and patient data are used to evaluate the method. For SPECT image reconstruction, non-uniform attenuation correction is performed with a truncated attenuation map, an extrapolated attenuation map and the untruncated attenuation map. The SPECT results indicate that image uniformity changes very little using any of the three different attenuation maps when a long focal length fan beam collimator is used for transmission data acquisition. Truncation artifacts that are apparent in the transmission image can be substantially reduced for objects up to 40 cm wide.
