Noise exposure of opera musicians (2008)

A previous noise exposure survey involving the Canadian Opera Company (COC) orchestra followed several musicians over the course of two operas (Lee, Behar, Wong, and Kunov, 2005) and found that the musicians were not at risk.Since then, the COC has moved to a new building.Thus, a new study was conducted to examine whether the new venue would have an effect on noise exposure.Measurements were taken during three performances of five different operas using five dosimeters attached to music stands located throughout the orchestra pit.While the exposure levels were found to be different across operas and instrument sections, these effects were independent.In general, the exposure levels were slightly lower in the new building for all musicians with woodwinds showing a large decrease.These decreases are likely due to a larger and less enclosed orchestra pit along with fewer brass musicians playing under the pit roof.While the present study did not find evidence for a risk of hearing loss for work performed in the new venue, the musicians engage in a variety of activities outside the COC that when added to their COC work may pose a risk of noise induced hearing loss. r s u m Une prcdente tude sur l 'exposition sonore des musiciens de l 'orchestre du Canadian Opera Company (COC) avait suivi plusieurs musiciens pendant deux opras (Lee, Behar, Wong et Kunov, 2005).Elle avait conclue que les musiciens ne couraient aucun danger.Depuis, le COC a dmnag dans un nouvel immeuble.Une nouvelle tude a donc t effectue pour examiner si la nouvelle salle avait une incidence sur l 'exposition sonore des musiciens.Les donnes ont t captures pendant trois performances de cinq opras diffrents en utilisant cinq dosimtres fixs des lutrins disperss dans la fosse d 'orchestre.Il a t trouv que les niveaux d 'exposition calculs diffraient d 'un opra l 'autre et d 'un endroit l 'autre dans la fosse; ces effets restaient indpendants.En gnral, le niveau d 'exposition tait plus bas dans le nouvel immeuble pour tous les musiciens.Une diminution significative a t remarque pour les instruments vent en bois.Cette diminution est principalement attribue une fosse plus grande et plus ouverte en plus d'avoir moins de cuivres jouant sous la vote de la fosse.Mme si cette tude n 'a pas trouv d 'vidence de risque de perte auditive pour tout travail effectu dans la nouvelle salle, il est noter que les musiciens du COC jouent aussi dans d 'autres salles et que l 'ajout des ces activits en plus de leur travail au COC peut crer un risque d 'une perte auditive.
New Compounds for Hydrogen Sulfide Scavenging and Iron Sulfide Control (2011)

Abstract New compounds have demonstrated effective scavenging of hydrogen sulfide with potential for preventing deposition of metal sulfides. These compounds come from a variety of functional families and compete against typical scavenging technology well with respect to molar efficiency, reaction rate, and stability. These inhibitors not only work on existing sulfide but some can also be modified to change the oxidation state of the system to provide a non-scaling scenario. The presence of hydrogen sulfide is an ever increasing problem in the oilfield, whether the origin is biological or formation dependant. The presence of extremely toxic hydrogen sulfide increases the corrosion rates of many metals and makes necessary the sweetening of produced hydrocarbon. If solubilized metals such as iron, lead or zinc are present in the fluid, the deposition of sulfides may occur as flow restrictive scale on the tubulars, leading to corrosion and/or biofilm augmentation or formation damaging fine particulate in the pay zone. These single component inhibitors were tested in standard synthetic formation waters which were either sulfide laden and/or metal or sulfide laden. Waters derived were standard unadulterated species at various pHs or were acidified and then spent on carbonate. The rate of sulfide uptake was monitored and the soluble metal ions were determined. Response surfaces were generated for a few key inhibitors and the performance of the inhibitors was compared to standard inhibitors. Stability was also checked to ensure insoluble or reversible scavenging species were measured. The use of these scavengers for drilling, stimulation, completion, and produced fluids provides the service company and/or operator with a viable treatment for problems incurred when treating sour reservoirs.
Waveguide T-junction as a broadband terahertz variable power splitter (2016)

We demonstrate a parallel-plate waveguide (PPWG) T-junction used as a power splitting router. We are able to direct the THz light down either one of the two output channels by integrating a small triangular septum into the waveguide plate. We find good agreement between experiment and simulation in both amplitude and phase. We show that the ratio between waveguide outputs varies exponentially with septum translation offset and that nearly 100% transmission can be achieved. The splitter operates over almost the entire range in which the waveguide is single mode, providing a sensitive and broadband method for THz power splitting.
Acquired von Willebrand Syndrome Associated with Hashimoto's Thyroiditis and Subcutaneous Mucosa-associated Lymphoid Tissue Lymphoma (2013)

Acquired von Willebrand syndrome (AVWS) is a rare bleeding disorder with laboratory findings similar to those of congenital von Willebrand disease. We herein report a case of AVWS associated with Hashimoto's thyroiditis and subcutaneous mucosa-associated lymphoid tissue lymphoma. An IgG autoantibody against von Willebrand factor (VWF) was detected. The antibody bound to VWF but did not inhibit VWF activity. Rapid clearance of VWF seemed to be the cause of AVWS in the present case. VWF-containing concentrates stopped the bleeding. Even if such a complication is rare, for AVWS patients, prompt recognition of the underlying mechanism can save lives.
4-Aminothiazolyl Analogues of GE2270 A: Antibacterial Lead Finding (2011)

4-Aminothiazolyl analogues of the antibacterial natural product GE2270 A (1) were designed, synthesized, and evaluated for gram positive bacteria growth inhibition. The aminothiazole-based chemical template was evaluated for chemical stability, and its decomposition revealed a novel, structurally simplified, des-thiazole analogue of 1. Subsequent stabilization of the 4-aminothiazolyl functional motif was achieved and initial structure activity relationships defined.
Malignant Transformation of Fanconi Anemia Complementation Group D2-deficient (Fancd2−/−) Hematopoietic Progenitor Cells by a Single HPV16 Oncogene (2019)

A single HPV16 oncogene is adequate to produce malignant transformation of Fancd2<sup>-/-</sup> hematopoietic cells.
Local transform processing of single-trial evoked potential (2003)

An algorithm for estimation and reconstruction of Evoked Potentials (EP), masked by EEG activity and additional sources of clutter and noise is proposed. The local Karhunen-Loeve (LKL) basis, derived from the noisy EP signal, is used for optimal signal representation. The vector space of the noisy signal is decomposed by the LKL transform into two complementary orthogonal subspaces. The EP signal is estimated by modifying the signal subspace components with a Wiener gain function.
Abstract 15571: Effect of Cardiac Stem Cells in Patients with Ischemic Cardiomyopathy: Interim Results of the SCIPIO Trial (2011)

Methods for directly turning a somatic cell type into another type (a process referred to as transdifferentiation) would be beneficial for producing replacement cells for therapeutic applications. Adult stem cells have been shown to display a broader differentiation potential than anticipated and may contribute to tissues other than those in which they reside. In addition, novel transdifferentiation strategies are being developed. I report recent results on the functional reprogramming of a somatic cell using a nuclear and cytoplasmic extract derived from another somatic cell type. The reprogramming of 293T fibroblasts in an extract from T cells is evidenced by nuclear uptake and the assembly of transcription factors, induction of activity of a chromatin remodelling complex, changes in chromatin composition and activation of lymphoid cell-specific genes. The reprogrammed cells express T-cell-specific surface molecules and a complex regulatory function. Reprogramming cells in cell-free extracts may create possibilities for producing replacement cells for therapeutic applications. The system may also constitute a powerful tool to examine the mechanisms of nuclear reprogramming, at least as they occur in vitro.
Search and retrieval of medical images for improved diagnosis of neurodegenerative diseases (2007)

In the medical world, the accuracy of diagnosis is mainly affected by either lack of sufficient understanding of some diseases or the inter-, and/or intra-observer variability of the diagnoses. The former requires understanding the progress of diseases at much earlier stages, extraction of important information from ever growing amounts of data, and finally finding correlations with certain features and complications that will illuminate the disease progression. The latter (inter-, and intra- observer variability) is caused by the differences in the experience levels of different medical experts (inter-observer variability) or by mental and physical tiredness of one expert (intra-observer variability). We believe that the use of large databases can help improve the current status of disease understanding and decision making. By comparing large number of patients, some of the otherwise hidden relations can be revealed that results in better understanding, patients with similar complications can be found, the diagnosis and treatment can be compared so that the medical expert can make a better diagnosis. To this effect, this paper introduces a search and retrieval system for brain MR databases and shows that brain iron accumulation shape provides additional information to the shape-insensitive features, such as the total brain iron load, that are commonly used in the clinics. We propose to use Kendall's correlation value to automatically compare various returns to a query. We also describe a fully automated and fast brain MR image analysis system to detect degenerative iron accumulation in brain, as it is the case in Alzheimer's and Parkinson's. The system is composed of several novel image processing algorithms and has been extensively tested in Leiden University Medical Center over so far more than 600 patients.

Game Balancing using Koopman-based Learning (2021)

This paper addresses the analysis of how the outcome of a zero-sum two-player game is affected by the value of numerical parameters that are part of the game rules and/or winning criterion. This analysis aims at selecting numerical values for such parameters that lead to games that are “fair” or “balanced” in spite of the fact that the two players may have distinct attributes/capabilities. Motivated by applications of game balancing for the commercial gaming industry, our effort is focused on complex multi-agent games for which low-dimensional models in the form of differential or difference equations are not possible or not available. To overcome this challenge, we use a parameter-dependent Koopman operator to model the game evolution, which we train using an ensemble of simulation traces of the actual game. This model is subsequently used to determine values for the game parameters that optimize the appropriate game balancing criterion. The approach proposed here is illustrated and validated on a minigame derived from the StarCraft II real-time strategy game from Blizzard Entertainment.
Phase-shifting point diffraction interferometer mask designs (2023)

In a phase-shifting point diffraction interferometer, different image-plane mask designs can improve the operation of the interferometer. By keeping the test beam window of the mask small compared to the separation distance between the beams, the problem of energy from the reference beam leaking through the test beam window is reduced. By rotating the grating and mask 45.degree., only a single one-dimensional translation stage is required for phase-shifting. By keeping two reference pinholes in the same orientation about the test beam window, only a single grating orientation, and thus a single one-dimensional translation stage, is required. The use of a two-dimensional grating allows for a multiplicity of pinholes to be used about the pattern of diffracted orders of the grating at the mask. Orientation marks on the mask can be used to orient the device and indicate the position of the reference pinholes.
A Comparative Study of Energy Minimization Methods for Markov Random Fields with Smoothness-Based Priors (2008)

Among the most exciting advances in early vision has been the development of efficient energy minimization algorithms for pixel-labeling tasks such as depth or texture computation. It has been known for decades that such problems can be elegantly expressed as Markov random fields, yet the resulting energy minimization problems have been widely viewed as intractable. Recently, algorithms such as graph cuts and loopy belief propagation (LBP) have proven to be very powerful: for example, such methods form the basis for almost all the top-performing stereo methods. However, the tradeoffs among different energy minimization algorithms are still not well understood. In this paper we describe a set of energy minimization benchmarks and use them to compare the solution quality and running time of several common energy minimization algorithms. We investigate three promising recent methods graph cuts, LBP, and tree-reweighted message passing in addition to the well-known older iterated conditional modes (ICM) algorithm. Our benchmark problems are drawn from published energy functions used for stereo, image stitching, interactive segmentation, and denoising. We also provide a general-purpose software interface that allows vision researchers to easily switch between optimization methods.

CHEMICAL CONTROL OF REPRODUCTION IN BIVALVE AND GASTROPOD MOLLUSCS, III:AN INEXPENSIVE TECHNIQUE FOR MARICULTURE OF MANY SPECIES (1978)

Abstract The addition of hydrogen peroxide to alkaline seawater provides an inexpensive, simple, and reliable method for the control and synchronous induction of broadcast spawning in males and females of certain bivalve and gastropod molluscs. Species successfully induced by this method thus far include:abalones ( Haliotis rufescens, H. corrugata , and H. fulgens ), mussels ( Mytilus edulis and M. californianus ), purple‐hinged rock scallop ( Hinnites giganteus ) and the mangrove oyster ( Crassostrea rhizophora ). Enzymological and physiological studies indicate that spawning may result from a peroxide‐induced stimulation of the endogenous enzymatic synthesis of potent hormone‐like prostaglandin molecules. Peroxide‐stimulated prostaglandin synthetase also has been found in reproductive tissues of certain crabs and fishes, thus indicating potential applicability of this method for the control of reproduction in higher species. However, internally fertilized gastropods, such as the queen conch ( Strombus gigas ), show no induction of reproductive behavior or egg‐laying (after mating) upon exposure to H 2 o 2 .
Combined experimental and numerical method for loss separation in permanent magnet brushless machines (2014)

Permanent magnet synchronous machines are a high efficiency motion solution. As the efficiency bar is raised, it is no longer adequate to consider only the dominant core, DC conduction and friction losses. The challenge for motor developers experiencing additional losses is determining which of the previously neglected losses is significant for their motor. This research presents a best-fit least-squares approach to loss separation that can be applied to experimental data to highlight the source of additional losses. This is a powerful tool for practical motor designers looking to meet challenging specifications. The proposed technique has been applied to the experimental data from three different prototype motors. Although a simple core model of core loss is used, in each case the losses were classified with a residual of less than 2%. Each loss type (defined by proportionality to speed and current) showed good agreement with the corresponding loss type calculated from FEA.
Distributed Estimation Using Reduced-Dimensionality Sensor Observations (2007)

We derive linear estimators of stationary random signals based on reduced-dimensionality observations collected at distributed sensors and communicated to a fusion center over wireless links. Dimensionality reduction compresses sensor data to meet low-power and bandwidth constraints, while linearity in compression and estimation are well motivated by the limited computing capabilities wireless sensor networks are envisioned to operate with, and by the desire to estimate random signals from observations with unknown probability density functions. In the absence of fading and fusion center noise (ideal links), we cast this intertwined compression-estimation problem in a canonical correlation analysis framework and derive closed-form mean-square error (MSE) optimal estimators along with coordinate descent suboptimal alternatives that guarantee convergence at least to a stationary point. Likewise, we develop estimators based on reduced-dimensionality sensor observations in the presence of fading and additive noise at the fusion center (nonideal links). Performance analysis and corroborating simulations demonstrate the merits of the novel distributed estimators relative to existing alternatives.

Lattice-structured proof technique applied to a minimum spanning-tree algorithm. Technical report (1988)

Highly-optimized concurrent algorithms are often hard to prove correct because they have no natural decomposition into separately provable parts. This paper presents a proof technique for the modular verification of such nonmodular algorithms. It generalizes existing verification techniques based on a totally-ordered hierarchy of refinements to allow a partially-ordered hierarchy - that is, a lattice of different views of the algorithm. The technique is applied to the well-known distributed minimum spanning-tree algorithm of Gallager, Humblet and Spira, which was until recently lacked a rigorous proof.
Enhanced Film Grain Noise Removal for High Fidelity Video Coding (2013)

In this paper, we propose a novel technique for film grain noise removal, which can be adopted in high fidelity video coding. Film grain noise enhances the natural appearance of high fidelity video, therefore it is should be preserved. However, film grain noise is a burden to typical video compression systems because it has relatively large energy level in the high frequency region. In order to improve the coding performance while preserving film grain noise, the noise removal and synthesis process is used. We propose a film grain noise removal technology in the pre-processing step. In pre-processing step, film grain noise is removed by using temporal, spatial and inter-color correlation. Specially, color image denoisng using inter color prediction provides good denoising performance in noise concentrated B plane because film grain noise has inter-color correlation in the RGB domain. The results show that the coding gain of denoised video is higher than for previous works, while the visual quality of the final reconstructed video is well preserved.
Neosiphoniamolide A, a Novel Cyclodepsipeptide, with Antifungal Activity from the Marine Sponge Neosiphonia superstes (1995)

A novel cyclodepsipeptide, neosiphoniamolide A [1], has been isolated from the sponge Neosiphonia superstes. The structure of 1, which contains a 12-carbon hydroxy acid, glycine, valine, and a halogenated tyrosine residue in an 18-membered ring, is related to jaspamide and the geodiamolides, previously isolated from sponges. The structure was solved by spectroscopic analysis.
