Transformation of adaptive thresholds by significance invariance for change detection (2005)

The detection of changes in image sequences often is the first essential step to video analysis, e.g. for the detection, classification and tracking of moving objects. As a binary classification problem, change detection is afflicted by the trade-off between two class error probabilities, viz. the rates of false positives and false negatives. In this contribution, we derive an adaptive two-threshold scheme to improve on this trade-off. The threshold selection for each pixel in the current frame is controlled by the previous detection result for this pixel. Since the test statistics are calculated from samples comprising several pixels within a local sliding window, a transformation of the thresholds from the single-pixel observations to decisions based on larger samples is required. Based on the fact that we can only model the null hypothesis, i.e. absence of motion, realistically, we suggest transforming the threshold under the constraint of a constant false-positive rate, or significance invariance the resulting detection algorithm is only marginally more complex than a straightforward global thresholding procedure, while providing visibly improved results

A new method for stabilizing softwood kraft lignin fibers for carbon fiber production (2012)

Abstract Renewable resources, such as kraft lignin, have shown great potential as precursors for carbon fiber production. This manuscript reports an investigation into the stabilization of softwood kraft lignin (SKL) fibers and the determination of the difference in stabilization between hardwood‐ and softwood‐based kraft lignin fibers. The stabilization was achieved either thermally by using only heat or oxidatively in the presence of air, at various heating rates. A heating rate of 4°C min −1 and a holding time of 30 min at 250°C were successfully used for the thermal stabilization experiments. Faster stabilization was achieved using oxidative conditions at a heating rate of 15°C min −1 and 30 min holding time at 250°C. Furthermore, stabilization and carbonization in a one‐step process was performed on SKL fibers, which show great potential to reduce both production time and costs. The stabilized and carbonized fibers were evaluated using thermal, spectroscopic, and microscopic methods. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

In vivo DNA-protein interactions at the divergent mercury resistance (mer) promoters. I. Metalloregulatory protein MerR mutants. (1993)

Regulation of transcriptional initiation of the Tn21 mercury resistance (mer) operon occurs at the divergent promoter region lying between the structural genes (merTPCAD) and a regulatory gene (merR). During repression, both promoters are negatively regulated by MerR bound to a dyadic operator located between the -10 and -35 hexamers of PTPCAD. Upon Hg(II) induction, MerR activates transcription only from PTPCAD and continues to repress transcription from PR. Using in vivo dimethyl sulfate and KMnO4 footprinting of the merOP region of strains carrying wild-type MerR or MerR mutants, we have dissected the steps in MerR-mediated positive and negative regulation of the divergent mer promoters. The greater sensitivity of primer extension footprinting allowed the resolution of details previously undetectable in vivo. Two MerR mutants unable to bind merOP DNA allow RNA polymerase to form an open complex preferentially at PR. The intensity of the PR open complex is considerably less than that which occurs upon MerR-Hg(II) activation of PTPCAD and considerably greater than that which occurs at PTPCAD when MerR is deleted; this is the first in vivo estimate of the relative strengths of these two promoters. Although retaining the wild-type capacity to sequester RNA polymerase in the closed complex, the four MerR mutants defective in Hg(II) binding do not distort the dyad DNA or foster open complex formation when the inducer is added. Two activation-defective MerR mutants foster closed complex formation as well as wild-type, but they do not distort the dyad DNA or foster open complex formation when the inducer is added, although they are also able to bind Hg(II). Two semiconstitutive inducible MerR mutants differ from each other in that one (which lies nearer the COOH terminus) does distort the dyad center upon Hg(II) induction, whereas the other (which lies in near the center of merR) exhibits no dyad distortion upon induction. Paradoxically, despite their relatively strong semiconstitutive expression of mer-lac transcriptional fusions, neither of these mutants has a detectable open complex in the absence of added Hg(II).
Opioid peptides from milk proteins. (1986)

Fragment peptides of milk proteins containing Tyr-X-Phe or Tyr-X1-X2-Phe were synthesized and their opioid activities were evaluated by the guinea pig ileum and radioreceptor assays. Among the peptides tested, the human β-casein(51 - 54) amide, Tyr-Pro-Phe-Val-NH2 (valmuceptin) was the most active, more than the bovine counterpart, morphiceptin. The human β-casein(41 - 44) amide, Tyr-Pro-Ser-Phe-NH2, and the α-lactalbumin (50-53) amide, Tyr-Gly-Leu-Phe-NH2, were also active in the guinea pig ileum assay. These were named β-casorphin and α-lactorphin, respectively. All of these peptides were not as active in the mouse and rabbit vas deferens assays.
Formulation of insect controlling agents with β‐cyclodextrin (1990)

Abstract Two insecticides, an insect repellent and an insecticide synergist have been complexed with β‐cyclodextrin yielding microcrystalline, wettable, non‐hygroscopic formulations. The insecticides fenitrothion and malathion, the repellent diethyltoluamide and the synergist MGR‐264 were found to form stable inclusion complexes with β‐cyclodextrin . The molecular encapsulation resulted in improved heat and chemical stability, storability, enhanced wettability and dissolution properties of these rather volatile, poorly water‐soluble agents .
Trip Planning Query Based on Partial Sequenced Route Algorithm (2019)

In Smart tourism field, the trip planning has some important features that include selection of points of interest, path routing, and trip time. Android application of trip planning is developed based on Partial Sequenced Route (PSR) algorithm for finding the optimal route in cultural heritage region Bagan, Myanmar. The optimal route is searched the sequence route according to the user-selected categories from the current location. The advanced routing method is proposed to provide the user trip without overlap route. The proposed approached is based on the modified nearest neighbor search in the road networks algorithm. The system also finds a meeting place for two users in different location.
Do-It-Yourself Virtual Memory Translation (2017)

In this paper, we introduce the Do-It-Yourself virtual memory translation (DVMT) architecture as a flexible complement for current hardware-fixed translation flows. DVMT decouples the virtual-to-physical mapping process from the access permissions, giving applications freedom in choosing mapping schemes, while maintaining security within the operating system. Furthermore, DVMT is designed to support virtualized environments, as a means to collapse the costly, hardware-assisted two-dimensional translations. We describe the architecture in detail and demonstrate its effectiveness by evaluating several different DVMT schemes on a range of virtualized applications with a model based on measurements from a commercial system. We show that different DVMT configurations preserve the native performance, while achieving speedups of 1.2x to 2.0x in virtualized environments.
Heuristic optimization of the scanning path of particle therapy beams (2009)

Quasidiscrete scanning is a delivery strategy for proton and ion beam therapy in which the beam is turned off when a slice is finished and a new energy must be set but not during the scanning between consecutive spots. Different scanning paths lead to different dose distributions due to the contribution of the unintended transit dose between spots. In this work an algorithm to optimize the scanning path for quasidiscrete scanned beams is presented. The classical simulated annealing algorithm is used. It is a heuristic algorithm frequently used in combinatorial optimization problems, which allows us to obtain nearly optimal solutions in acceptable running times. A study focused on the best choice of operational parameters on which the algorithm performance depends is presented. The convergence properties of the algorithm have been further improved by using the next-neighbor algorithm to generate the starting paths. Scanning paths for two clinical treatments have been optimized. The optimized paths are found to be shorter than the back-and-forth, top-to-bottom (zigzag) paths generally provided by the treatment planning systems. The gamma method has been applied to quantify the improvement achieved on the dose distribution. Results show a reduction of the transit dose when the optimized paths are used. The benefit is clear especially when the fluence per spot is low, as in the case of repainting. The minimization of the transit dose can potentially allow the use of higher beam intensities, thus decreasing the treatment time. The algorithm implemented for this work can optimize efficiently the scanning path of quasidiscrete scanned particle beams. Optimized scanning paths decrease the transit dose and lead to better dose distributions.

Enzymatically Ligated DNA–Surfactants: Unmasking Hydrophobically Modified DNA for Intracellular Gene Regulation (2018)

Herein, we describe the characterization of a novel self-assembling and intracellular disassembling nanomaterial for nucleic acid delivery and targeted gene knockdown. By using a recently developed nucleic acid nanocapsule (NAN) formed from surfactants and conjugated DNAzyme (DNz) ligands, it is shown that DNz-NAN can enable cellular uptake of the DNAzyme and result in 60 % knockdown of a target gene without the use of transfection agents. The DNAzyme also exhibits activity without chemical modification, which we attribute to the underlying nanocapsule design and release of hydrophobically modified nucleic acids as a result of enzymatically triggered disassembly of the NAN. Fluorescence-based experiments indicate that the surfactant-conjugated DNAzymes are better able to access a fluorescent mRNA target within a mock lipid bilayer system than the free DNAzyme, highlighting the advantage of the hydrophobic surfactant modification to the nucleic acid ligands. In vitro characterization of DNz-NAN's substrate-cleavage kinetics, stability in biological serum, and persistence of knockdown against a proinflammatory transcription factor, GATA-3, are presented.
Amplification of anion sensing by disulfide functionalized ferrocene and ferrocene-calixarene receptors adsorbed onto gold surfaces (2010)

A disulfide functionalized bis-ferrocene urea acyclic receptor and disulfide functionalized mono- and bis-ferrocene amide and urea appended upper rim calix[4]arene receptors were prepared for the fabrication of SAM redox-active anion sensors. 1H NMR and diffusive voltammetric anion recognition investigations revealed each receptor to be capable of complexing and electrochemically sensing anions via cathodic perturbations of the respective receptor's ferrocene/ferrocenium redox couple. SAMs of a ferrocene urea receptor 3 and ferrocene urea calixarene receptor 17 exhibited significant enhanced magnitudes of cathodic response upon anion addition as compared to observed diffusive perturbations. SAMs of 17 were demonstrated to sense the perrhenate anion in aqueous solutions.
Review of the Consumer Perspective Framework for Healthcare Applications (2014)

Cummings, Borycki, and Roehrer (2013) developed a Consumer Perspectives Framework that identified a range of consumer-related issues and concerns that should be considered when downloading and using healthcare applications for mobile phones. The framework identifies data-related issues with mobile applications, such as ownership, location, completeness, corporate use, storage, and privacy. This chapter documents research undertaken in confirming the Consumer Perspectives Framework. Finally, the authors propose a method by which the Consumer Perspectives Framework can be implemented for use by consumers prior to downloading healthcare applications.
Parallel double error correcting code design to mitigate multi-bit upsets in SRAMs (2008)

The range of SRAM multi-bit upsets (MBU) in sub-100 nm technologies is characterized using irradiation tests on two prototype ICs, developed in 90 nm commercial processes. Results reveal that MBU, as large as 13-bit, can occur in these technologies, limiting the efficacy of conventional SEC-DED error-correcting codes (ECC). A double-error correcting (DEC) ECC implementation technique suitable for SRAM applications is presented. Results show that this DEC scheme reduces errors by 98.5% compared to only 44% reduction by conventional SEC-DED ECC.
Carbon monoxide poisoning of proton exchange membrane fuel cells (2001)

Proton exchange membrane fuel cell (PEMFC) performance degrades when carbon monoxide (CO) is present in the fuel gas; this is referred to as CO poisoning. This paper investigates CO poisoning of PEMFCs by reviewing work on the electrochemistry of CO and hydrogen, the experimental performance of PEMFCs exhibiting CO poisoning, methods to mitigate CO poisoning and theoretical models of CO poisoning. It is found that CO poisons the anode reaction through preferentially adsorbing to the platinum surface and blocking active sites, and that the CO poisoning effect is slow and reversible. There exist three methods to mitigate the effect of CO poisoning: (i) the use of a platinum alloy catalyst, (ii) higher cell operating temperature and (iii) introduction of oxygen into the fuel gas flow. Of these three methods, the third is the most practical. There are several models available in the literature for the effect of CO poisoning on a PEMFC and from the modeling efforts, it is clear that small CO oxidation rates can result in much increased performance of the anode. However, none of the existing models have considered the effect of transport phenomena in a cell, nor the effect of oxygen crossover from the cathode, which may be a significant contributor to CO tolerance in a PEMFC. In addition, there is a lack of data for CO oxidation and adsorption at low temperatures, which is needed for detailed modeling of CO poisoning in PEMFCs. Copyright © 2001 John Wiley & Sons, Ltd.

Alternative Exon Splicing Controls a Translational Switch from Activator to Repressor Isoforms of Transcription Factor CREB during Spermatogenesis (1996)

The cAMP/protein kinase A signaling pathway activates the cAMP-responsive transcription factor CREB. Here we describe a unique alternative RNA splicing event that occurs during the development of germ cells in the testis, resulting in a translational switch from an mRNA encoding activator CREB to an mRNA encoding novel inhibitor CREB isoforms (I-CREBs). Alternative splicing of an additional exon into the CREB mRNA in mid to late pachytene spermatocytes results in the premature termination of translation and consequent downstream reinitiation of translation producing I-CREBs. The I-CREBs down-regulate cAMP-activated gene expression by inhibiting activator CREB from binding to cAMP response elements. Further, the developmental stage-specific expression of I-CREBs in germ cells of the seminiferous tubules correlates with the cyclical down-regulation of activator CREB, suggesting that I-CREBs repress expression of the cAMP-inducible CREB gene as well as other genes transiently induced by cAMP during the 12-day cycle of spermatogenesis.
A Comparison of 15% Azelaic Acid Gel and 0.75% Metronidazole Gel in the Topical Treatment of Papulopustular Rosacea (2003)

Use of 15% azelaic acid gel twice daily for 15 weeks demonstrated significant superiority over using 0.75% metronidazole gel in improving principal signs of rosacea (inflammatory lesions and erythema).
A first look at modern enterprise traffic (2005)

While wide-area Internet traffic has been heavily studied for many years, the characteristics of traffic inside Internet enterprises remain almost wholly unexplored. Nearly all of the studies of enterprise traffic available in the literature are well over a decade old and focus on individual LANs rather than whole sites. In this paper we present a broad overview of internal enterprise traffic recorded at a medium-sized site. The packet traces span more than 100 hours, over which activity from a total of several thousand internal hosts appears. This wealth of data---which we are publicly releasing in anonymized form---spans a wide range of dimensions. While we cannot form general conclusions using data from a single site, and clearly this sort of data merits additional in-depth study in a number of ways, in this work we endeavor to characterize a number of the most salient aspects of the traffic. Our goal is to provide a first sense of ways in which modern enterprise traffic is similar to wide-area Internet traffic, and ways in which it is quite different.
An Analysis of Photobleaching Techniques for the Radiation Hardening of Fiber Optic Data Links (1981)

The effects of light signals propagating within a fiber optic waveguide on the magnitude, spectral character and stability of radiation-induced optical absorption have been investigated. In particular, the prospects for the utilization of photobleaching techniques to increase the radiation hardness of fiber optic links has been assessed for typical state-of-the-art optical fibers. Both steady state and pulsed light sources have been employed. Fibers fabricated both from high purity synthetic silica and selectively doped silicas have been utilized. The nature of the photo-bleaching process in silica-based glasses is discussed and the characteristics of the photoluminescence accompanying the bleaching process are reported. It is concluded that the selective use of optical bleaching in irradiated fiber optic waveguides provides a useful method for increasing the operational hardness of a data link. This can be accomplished at modest power levels achievable with present day solid state light sources, and the system can be configured such that the transmitted and bleach signals are identical. The technique is most effective in pure silica core materials and promises to primarily impact systems with modest length requirements in which high light intensities can be launched throughout the link. Second generation waveguides with lower intrinsic losses will make the photobleaching approach useful even for extended ranges. The possibility of self-photobleaching waveguides containing luminescent ions is also discussed.
