Stereo Matching Using Tree Filtering (2014)

Matching cost aggregation is one of the oldest and still popular methods for stereo correspondence. While effective and efficient, cost aggregation methods typically aggregate the matching cost by summing/averaging over a user-specified, local support region. This is obviously only locally-optimal, and the computational complexity of the full-kernel implementation usually depends on the region size. In this paper, the cost aggregation problem is re-examined and a non-local solution is proposed. The matching cost values are aggregated adaptively based on pixel similarity on a tree structure derived from the stereo image pair to preserve depth edges. The nodes of this tree are all the image pixels, and the edges are all the edges between the nearest neighboring pixels. The similarity between any two pixels is decided by their shortest distance on the tree. The proposed method is non-local as every node receives supports from all other nodes on the tree. The proposed method can be naturally extended to the time domain for enforcing temporal coherence. Unlike previous methods, the non-local property guarantees that the depth edges will be preserved when the temporal coherency between all the video frames are considered. A non-local weighted median filter is also proposed based on the non-local cost aggregation algorithm. It has been demonstrated to outperform all local weighted median filters on disparity/depth upsampling and refinement.
The sequences of and distance between two cis-acting signals determine the efficiency of ribosomal frameshifting in human immunodeficiency virus type 1 and human T-cell leukemia virus type II in vivo (1994)

We have analyzed in cell culture the sequence elements that control the level of ribosomal frameshifting in the human T-cell leukemia virus type II (HTLV-2) gag-pro junction. The slippery sequence of HTLV-2 is sufficient to dictate a basal level of frameshifting. This level is enhanced by its upstream sequence context and by the downstream stem-loop structure which is located at an optimal distance of 7 bases. Frameshifting in human immunodeficiency virus gag-pol is similar to that of HTLV-2 gag-pro. However, experiments using hybrid cassettes of HTLV-2 and human immunodeficiency virus type 1 frameshift elements show that while the slippery sequence of HTLV-2 is less efficient, the stem-loop structure is a more efficient enhancer.
Allosteric Adenosine Modulation to Reduce Allodynia (2001)

These results add to previous studies that suggest ongoing spinal release of adenosine, which is antiallodynic, in this animal model of neuropathic pain. Positive allosteric modulation of the adenosine receptor reduces hypersensitivity by a spinal mechanism involving A1 adenosine receptor stimulation. Although obvious adverse effects were not observed in this investigation, further study is required to determine the feasibility of the use of such modulators in the treatment of chronic pain associated with hyperalgesia and allodynia.
On the Reliability of the IBM MVS/XA Operating System (1987)

This paper describes an analysis of system-detected errors on the MVS operating system under the eXtended Architecture (XA) for two IBM 3081 systems. The analysis classifies the errors in categories and examines the effectiveness of the recovery system of the MVS/XA. Comparison of the results for the two IBM 3081's confirm the dependence of the error distribution on the type of system utilization. The results for one of the machines are compared to those obtained for the same system when operating under MVS/SP. The comparison of the MVS/XA to the MVS/SP reveals the following: more addressing errors, a better error recording system and improved reliability and fault tolerance.
NKG2D ligand tumor expression and association with clinical outcome in early breast cancer patients: an observational study (2012)

We demonstrated for the first time that NKG2DL are frequently expressed and often co-expressed in breast cancer. Expression of MIC-AB and ULBP-2 resulted in a statistically significant beneficial outcome concerning RFP with high discriminative power. Combination of all NKG2DL showed no additive or interactive effect of ligands on each other, suggesting that similar and co-operative functioning of all NKG2DL can not be assumed. Our observations suggest that among driving forces in breast cancer outcome are immune activation on one site and tumor immune escape on the other site.
Color- and Texture-Based Image Segmentation for Improved Forest Delineation (2007)

This paper concentrates on the delineation of forest boundaries from aerial images with focus on spatially contiguous and reproducible results for the Swiss National Forest Inventory. Because of the poor performance of common edge models to extract natural vegetation boundaries, this paper presents a combined method of image segmentation and wavelet-based texture features for the delineation of forest. The selected -measure-based segmentation method has been found to be useful to produce initial segmentation results, but lacks a semantic concept for forest vegetation. To overcome this conceptual limitation, the combination with wavelet transformation gives access to additional texture features and leads to a robust approach to obtain proper forest boundaries. Preliminary results are encouraging regarding the better agreement compared with maximum-likelihood classification results.
Improved Small-Molecule Macroarray Platform for the Rapid Synthesis and Discovery of Antibacterial Chalcones (2011)

Bacterial resistance to current antibiotics is a major global health threat. Consequently, there is an urgent need for the identification of new antibacterial agents. We are applying the small-molecule macroarray platform to rapidly synthesize and screen compounds for activity against methicillin-resistant Staphylococcus aureus (MRSA). Herein, we report the synthesis of a 1,3-diphenyl-2-propen-1-one (chalcone) macroarray using a Rink-amide linker-derivatized cellulose support. The Rink linker allowed for the incorporation of a broader array of library building blocks relative to our previous syntheses because milder reaction conditions could be utilized; significantly higher compound loadings were also achieved (~80% vs ~15%). Analysis of the 174-member chalcone macroarray in off-support antibacterial screening assays revealed three chalcones with minimum inhibitory concentration (MIC) values against MRSA comparable to currently used antibacterial drugs and low hemolytic activities. These results serve to further showcase and extend the utility of the small molecule macroarray for antibacterial discovery.

Simvastatin Has Anti-Inflammatory and Antiatherosclerotic Activities Independent of Plasma Cholesterol Lowering (2001)

Abstract —Inhibitors of 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase, such as simvastatin, lower circulating cholesterol levels and prevent myocardial infarction. Several studies have shown an unexpected effect of HMG-CoA reductase inhibitors on inflammation. Here, we confirm that simvastatin is anti-inflammatory by using a classic model of inflammation: carrageenan-induced foot pad edema. Simvastatin administered orally to mice 1 hour before carrageenan injection significantly reduced the extent of edema. Simvastatin was comparable to indomethacin in this model. To determine whether the anti-inflammatory activity of simvastatin might affect atherogenesis, simvastatin was tested in mice deficient in apoE. Mice were dosed daily for 6 weeks with simvastatin (100 mg/kg body wt). Simvastatin did not alter plasma lipids. Atherosclerosis was quantified through the measurement of aortic cholesterol content. Aortas from control mice (n=20) contained 56±4 nmol total cholesterol/mg wet wt tissue, 38±2 nmol free cholesterol/mg, and 17±2 nmol cholesteryl ester/mg. Simvastatin (n=22) significantly ( P <0.02) decreased these 3 parameters by 23%, 19%, and 34%, respectively. Histology of the atherosclerotic lesions showed that simvastatin did not dramatically alter lesion morphology. These data support the hypothesis that simvastatin has antiatherosclerotic activity beyond its plasma cholesterol–lowering activity.

The viscosity behavior of linear and branched dextran sulfates (1962)

Abstract Linear and branched samples of potassium dextran sulfate have been prepared without significant degradation from samples of linear and branched dextran having similar intrinsic viscosities. The dilute solution viscosity behavior of these polyelectrolytes has been studied with particular reference to the effect of branching and degree of sulfation. A comparison of the reduced viscosity—concentration curves, in aqueous 0.001 N and 0.0005 N KCl, of linear and branched potassium dextran sulfate with the same degree of sulfation revealed a significant difference in their viscosity behavior. This difference is attributed to a greater charge density in the nonlinear sample resulting from its branched structure.

A spatiotemporal denoising scheme for a mobile device (2015)

A fast spatiotemporal denoising algorithm for mobile devices is presented. The noise removal is achieved hierarchically in a multi-resolution framework which is combined with image registration and temporal bilateral filtering. In particular image registration and temporal filtering are designed to reduce computing complexity and memory bandwidth requirement while maintaining the quality of the denoising results. The proposed algorithm is implemented on retail camera products in which a coarse-grained reconfigurable processor is embedded. It is confirmed that the processing time is 2.9 seconds with four 20M pixels images by reducing computing complexity by 11% and the amount of data transfer by 24% comparing to the previous algorithm.
Glycyrrhizin (Licorice)-Induced Hypokalemic Myopathy (1992)

Fifty-nine cases of glycyrrhizin (licorice)-induced hypokalemic myopathy (GIHM), 2 females treated in our departments (85 and 73 years old) and 57 cases reported in the literature were studied, and conditions leading to the onset, factors, clinical manifestations, laboratory assessments, muscle biopsy findings, treatment and outcome were discussed. The 59 GIHM cases comprised 32 men, 25 women and 2 patients without record of sex; the average age was 55.2 years. In many cases, conditions leading to the onset of GIHM were habitual licorice ingestion, ingestion of antituberculosis agents containing licorice and long-term ingestion of licorice-containing agents for chronic gastritis, chronic hepatitis or chronic dermatitis. The combined use of hypotensive diuretic agents increased the risk of GIHM in an overwhelming number of cases. The main clinical symptom was flaccid quadriplegia in almost all cases, with muscle pain in 32.2% and peripheral dysesthesia in the extremities, manifested mainly by numbness (27.1%). Laboratory findings included a mean serum K+ value of 1.98 mEq/l (56 GIHM cases), a mean creatine kinase of 5,385.7 IU/l (n = 30), a mean blood aldosterone concentration of 2.92 ng/dl (n = 30; normal: 2.0-13.0 ng/dl) and a mean plasma renin activity of 0.17 ng/ml/h (n = 27; normal: 0.8-4.4 ng/ml/h). Muscle biopsy was performed in 17 of the 59 cases with resultant findings of myopathic changes consisting mainly of phagocytosis, necrotic fibers, vacuolar degeneration, together with sporadic neurogenic changes. Complete cure was attained in 57 of the 59 cases of GIHM by discontinued ingestion of glycyrrhizin (licorice) and potassium supplement.
Regioselective Preparation of N7- and N9-Alkyl Derivatives of N6-[(Dimethylamino)methylene]adenine Bearing an Active Methylene Group and Their Further Derivatization Leading to α-Branched Acyclic Nucleoside Analogues (1999)

N7- and N9-regioisomers of cyanomethyl and trifluoroethyl-N6-[(dimethylamino)methylene]adenine (1, 2, 6, 7) were prepared regioselectively, the former by the direct alkylation of N6-[(dimethylamino)methylene]adenine, the latter by the alkylation of adenine followed by protection of the amino group. These derivatives, which bear an active methylene group, were submitted to reactions with allyl bromide, aldehydes or tert-butoxybis(dimethylamino)methane in order to modify their side chain. In this way, several new α-branched acyclic adenosine analogues (8, 10–16) were prepared; the regioselectivity of the alkylation and the product structures were determined by 1H- and 13C-NMR spectroscopy. 15N-NMR parameters for selected compounds were studied by gradient-enhanced inverse-detected techniques. In addition, X-ray data of derivatives 1, 2 and 7 are reported.
Comparison of Depletion Strategies for the Enrichment of Low-Abundance Proteins in Urine (2015)

Proteome analysis of complex biological samples for biomarker identification remains challenging, among others due to the extended range of protein concentrations. High-abundance proteins like albumin or IgG of plasma and urine, may interfere with the detection of potential disease biomarkers. Currently, several options are available for the depletion of abundant proteins in plasma. However, the applicability of these methods in urine has not been thoroughly investigated. In this study, we compared different, commercially available immunodepletion and ion-exchange based approaches on urine samples from both healthy subjects and CKD patients, for their reproducibility and efficiency in protein depletion. A starting urine volume of 500 μL was used to simulate conditions of a multi-institutional biomarker discovery study. All depletion approaches showed satisfactory reproducibility (n=5) in protein identification as well as protein abundance. Comparison of the depletion efficiency between the unfractionated and fractionated samples and the different depletion strategies, showed efficient depletion in all cases, with the exception of the ion-exchange kit. The depletion efficiency was found slightly higher in normal than in CKD samples and normal samples yielded more protein identifications than CKD samples when using both initial as well as corresponding depleted fractions. Along these lines, decrease in the amount of albumin and other targets as applicable, following depletion, was observed. Nevertheless, these depletion strategies did not yield a higher number of identifications in neither the urine from normal nor CKD patients. Collectively, when analyzing urine in the context of CKD biomarker identification, no added value of depletion strategies can be observed and analysis of unfractionated starting urine appears to be preferable.
Fluorescence Sensing Using DNA Aptamers in Cancer Research and Clinical Diagnostics (2017)

Among the various advantages of aptamers over antibodies, remarkable is their ability to tolerate a large number of chemical modifications within their backbone or at the termini without losing significant activity. Indeed, aptamers can be easily equipped with a wide variety of reporter groups or coupled to different carriers, nanoparticles, or other biomolecules, thus producing valuable molecular recognition tools effective for diagnostic and therapeutic purposes. This review reports an updated overview on fluorescent DNA aptamers, designed to recognize significant cancer biomarkers both in soluble or membrane-bound form. In many examples, the aptamer secondary structure switches induced by target recognition are suitably translated in a detectable fluorescent signal using either fluorescently-labelled or label-free aptamers. The fluorescence emission changes, producing an enhancement (“signal-on”) or a quenching (“signal-off”) effect, directly reflect the extent of the binding, thereby allowing for quantitative determination of the target in bioanalytical assays. Furthermore, several aptamers conjugated to fluorescent probes proved to be effective for applications in tumour diagnosis and intraoperative surgery, producing tumour-type specific, non-invasive in vivo imaging tools for cancer pre- and post-treatment assessment.
Transition Edge X-ray Sensor Using Anodic Bonding Wafer (2002)

We describe the fabrication of Transition Edge X-ray Sensor(TES) using anodic bonding wafer that is suitable for large format array that is necessary for industrial application and astronomy. We also report the performance of TES for single pixel. The characteristic points of our fabrication are 1) use of silicon-to-glass bonding(anodic bonding) wafer, yielding the large mechanical strength of the wafer, 2) only front side patterning and etching, yielding the easy fabrication. The energy resolution of TES operated at 113 mK was 9.2 eV(FWHM) for Mn K<1(5899 eV) and effective decay time(τeff) 71 μs. The energy resolution is 10 times better than conventional silicon-detector(130eV) and the count rate(1/6τeff) reached about 2.4 kcps.
Comparative studies on adult donor lymphocytes infected by EB virus <i>in vivo</i> or <i>in vitro</i>: Origin of transformed cells arising in co‐cultures with foetal lymphocytes (1977)

Co-cultures were set up between equal numbers of mononuclear cells from the blood of EB virus-infected individuals, either acute IM patients or healthy seropositive adult donors, and foetal cord blood mononuclear cells of the opposite sex. The cell lines arising in the co-cultures were of mixed origin, with foetal cells predominating in many cases. In contrast, when mononuclear cells from seronegative adult donors were first infected with EB virus in vitro and then 5 to 12 days later co-cultured with a large excess of foetal cells of the opposite sex, the cell lines which arose were almost exclusively derived from the adult donor despite the fact that a small minority of the virus-infected adult cells released infectious virus capable of transforming the co-cultivated foetal cells. The experiments suggest that EB virus-infected cells present in the blood of IM patients and seropositive donors do not possess the capacity for unlimited in vitro growth shown by seronegative adult donor lymphocytes experimentally infected with the virus.
Phycoerythrin of the marine blue-green alga <italic>Trichodesmium thiebautii</italic> (1974)

Spectroscopic characteristics of the phycoerythrin obtained from the marine blue-green alga Trichodesmium thiebautii were investigated. The algal sample was collected at its natural habitat, the East China Sea. The phycoerythrin showed an absorption spectrum and a fluorescence excitation spectrum with three peaks in the visible wave-length region at 500, 547 and 565 nm. This property is very different from that of the cyanophycean phycoerythrin, which has a single peak at 565 nm, but it is similar to that of the rhodophycean phycoerythrin with three peaks at 500, 550 and 565 nm.
Fast Mesh Decimation by Multiple-Choice Techniques (2002)

We present a new mesh decimation framework which is based on the probabilistic optimization technique of Multiple-Choice algorithms. While producing the same expected quality of the output meshes, the Multiple-Choice approach leads to a significant speed-up compared to the wellestablished standard framework for mesh decimation as a greedy optimization scheme. Moreover, Multiple-Choice decimation does not require a global priority queue data structure which reduces the memory overhead and simplifies the algorithmic structure. We explain why and how the MultipleChoice optimization works well for the mesh decimation problem and give a detailed CPU profile analysis to explain where the speed-up comes from.
An approach to the selection of built-in-test devices (2002)

A procedure is described by which reliability and maintainability considerations can be taken into account when ranking options for the selection of built-in test (BIT) devices. The type of constraints that are likely to influence BIT selection usually fall into one of the following categories: money, space and weight, manpower, time, and computer power and memory. Quality measures-factors which influence the overall objectives sought when employing BIT-are increasing the availability and reliability of the system and decreasing the system's probability of a safety incident when the BIT is capable of detecting safety-critical failure modes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Nomenclature for New Tetracycline Resistance Determinants (1999)
