Corporate governance as a determinant of corporate values (2005)

Purpose This paper aims to test the impact of corporate governance structure on corporate values. Design/methodology/approach The paper employs factor analysis and three‐stage least squares to identify and explain variance in corporate values. Findings In accordance with the proposed theoretical framework ownership, board and stakeholder structure are found to influence corporate values. When value determinants are taken into account there is no significant relationship between values and profitability. Research limitations/implications This is a pilot study of 71 Danish firms. Further research needs to address measurement of corporate values and to test hypotheses on larger datasets. Practical implications One practical implication is that corporate values should be grounded in the company's ownership, board and stakeholder structure. Real changes in corporate values may require real changes in governance structure. Originality/value The paper tests a new approach to the study of corporate values which connects values to governance. It thereby establishes empirical foundations for current discussions about corporate values. This should be important both to practical work on company missions, values and responsibilities and to academics who search for an operational approach to the study of corporate values.
Production and characterization of doped mandrels for inertial-confinement fusion experiments (1994)

A key feature of current inertial-confinement fusion (ICF) experiments is the incorporation of dopant atoms into the thin polymer microshell which, in a finished ICF capsule, forms its inner wall. These dopants provide a spectroscopic signal during the implosion that can be used to diagnose the degree of mix at the capsule–fuel interface. The high-Z dopants can also be used to directly image the fuel–pusher interface. The current status of doped mandrel development is reviewed, with a focus on the mandrel surface smoothness. With the development of unique surface mapping characterization tools which will be described, it has been discovered that mandrel surface smoothness is a function of the polymers used to form the mandrels. In this report it will be shown that Cl-doped mandrels produced from a blend of polystyrene and poly(p-chlorostyrene) are rough on a length scale of 10’s of microns with amplitudes of as much as a 100 nm. The origin of this roughness will be discussed, and it will be shown that this roughness can be removed by using a copolymer rather than a blend of two polymers. Also it will be shown how Cr-doped mandrels become rough with age due to ambient light exposure.
Investigation of a copper etching technique to fabricate metallic gas diffusion media (2006)

A new fabrication technique based on etching is employed to convert a copper foil into a porous structure with an array of micron size pores. The motivation stems from the need to develop a more efficient and controllable gas diffusion medium for fuel cell applications. The influence of mask shape, mask width and etching time was investigated experimentally. A correlation to predict trench width with etching time was derived; normalizing by mask width allows one to collapse the data. The etching rates to obtain micro-scale features, which are of the order of 1–2 µ mm in –1 , are mainly dominated by the mask width due to mass-transport resistance. It is possible to control the pore dimensions, porosity and pore size distributions with this technique. (Some figures in this article are in colour only in the electronic version)
DeepPump: Multi-pumping deep Neural Networks (2017)

This paper presents DeepPump, a novel approach for generating and optimising hardware designs of deep Convolutional Neural Networks (CNNs) with multi-pumping on FPGA platforms. Multi-pumping [1] is a promising technique to save hardware resource usage by replacing M parallel units with one clocked at M times the global clock rate. DeepPump aims at automatically adopting multi-pumping when generating hardware designs for CNNs. It has three components: a parameterised CNN accelerator architecture that supports multi-pumping, a design model for trade-off analysis related to multi-pumping, and an optimisation flow for improving the architecture based on the design model.
Mechanical effects of obesity on airway responsiveness in otherwise healthy humans (2009)

We investigated whether obesity is associated with airway hyperresponsiveness in otherwise healthy humans and, if so, whether this correlates with a restrictive lung function pattern or a decreased number of sighs at rest and/or during walking. Lung function was studied before and after inhaling methacholine (MCh) in 41 healthy subjects with body mass index ranging from 20 to 56. Breathing pattern was assessed during a 60-min rest period and a 30-min walk. The dose of MCh that produced a 50% decrease in the maximum expiratory flow measured in a body plethysmograph (PD50MCh) was inversely correlated with body mass index (r2=0.32, P<0.001) and waist circumference (r2=0.25, P<0.001). Significant correlations with body mass index were also found with the maximum changes in respiratory resistance (r2=0.19, P<0.001) and reactance (r2=0.40, P<0.001) measured at 5 Hz. PD50MCh was also positively correlated with functional residual capacity (r2=0.56, P<0.001) and total lung capacity (r2=0.59, P<0.001) in men, but not in women. Neither PD50MCh nor body mass index correlated with number of sighs, average tidal volume, ventilation, or breathing frequency. In this study, airway hyperresponsiveness was significantly associated with obesity in otherwise healthy subjects. In obese men, but not in women, airway hyperresponsiveness was associated with the decreases in lung volumes.

Optimization of a depth of interaction encoding PET block detector for a PET/MRI insert (2018)

Preclinical positron emission tomography, combined with magnetic resonance imaging (PET/MRI), is increasingly used as a tool to simultaneously characterize functional processes in vivo. Many emerging preclinical applications, however, are limited by PET detection sensitivity, especially when generating short imaging frames for quantitative studies. One such application is dynamic multifunctional imaging, which probes multiple aspects of a biological process, using relationships between the datasets to quantify interactions. These studies have limited accuracy due to the relatively low sensitivity of modern preclinical PET/MRI systems. The goal of this project is to develop a preclinical PET/MRI insert with detection sensitivity above 15% (250-750 keV) to improve quantitation in dynamic PET imaging. To achieve this sensitivity, we have developed a detector module incorporating a 2 cm thick crystal block, which will be arranged into a system with 8 cm axial FOV, targeting mice and rats. To maintain homogenous spatial resolution, the detector will incorporate dual-ended depth-of-interaction (DOI) encoding with silicon photomultiplier (SiPM) based photodetector arrays. The specific aim of this work is to identify a detector configuration with adequate performance for the proposed system. We have optimized the SiPM array geometry and tested two crystal array materials with pitch ranging from 0.8 to 1.2 mm and various surface treatments and reflectors. From these configurations, we have identified the best balance between crystal separation, energy resolution, and DOI resolution. The final detector module uses two rectangular SiPM arrays with 5 × 6 and 5 × 4 elements. The photodetector arrays are coupled to a 19 × 19 array of 1 mm pitch LYSO crystals with polished surfaces and a diffuse reflector. The prototype design has 14.3% ± 2.9% energy resolution, 3.57 ± 0.88 mm DOI resolution, and resolves all elements in the crystal array, giving it sufficient performance to serve as the basis for the proposed high sensitivity PET/MRI insert.
The role of growth hormone in the pathogenesis of diabetic kidney disease. (2004)

At present, diabetic kidney disease affects about 15-20% of all Type 1 diabetic patients and 20-40% of all patients with Type 2 diabetes. Preclinical research performed over the past decade has suggested growth hormone (GH) and insulin-like growth factors (IGFs) to be involved in the pathogenesis of diabetic kidney disease. Data obtained in knock-out (KO) mice with GH receptor (GHR)/GH binding protein (GHBP) gene-disruption have shown that these animals are protected against diabetes-induced renal changes. Further, diabetic mice treated with either a longacting somatostatin analogue or a specific GHR antagonist (GHRA) showed normalization of the diabetes-associated renal hypertrophy and glomerular enlargement and most importantly also a lowering effect on the diabetes-induced rise in urinary albumin excretion (UAE), a marker of renal damage. Based on these experimental data future studies are warranted to characterize the clinical potential of GH-inhibitors (e.g. GHRAs) as drugs for the treatment of diabetic renal complications.
Expression of LacZ from the htrA, nirB and groE promoters in a Salmonella vaccine strain: Influence of growth in mammalian cells (1995)

Attenuated Salmonella strains are currently being evaluated as live vectors for the delivery of heterologous antigens to the mammalian mucosal and systemic immune systems. An approach to improving the stability of heterologous antigen expression during vaccination is to drive expression of the foreign protein from promoters e.g. nirB, that become activated when Salmonella enter the host. Salmonella strains were constructed that harboured similar multicopy plasmids encoding the lacZ gene. In each strain, lacZ expression was driven from either the nirB, htrA or groE promoters. Expression of LacZ increased in all vaccine strains as they were shifted from conditions of low to high temperature. In addition, expression of lacZ driven from the htrA and nirB promoters significantly increased when the Salmonella entered eukaryotic cells, including macrophages. Expression of lacZ from the groE promoter was significantly elevated in macrophages but not in cells derived from epithelia. These promoters may be useful for optimising heterologous antigen expression within immune cells of the host.
Gallium arsenide and aluminum gallium arsenide reactive ion etching in boron trichloride/argon mixtures (1987)

GaAs and Al0.3Ga0.7As were reactive ion etched in a mixture of boron trichloride and argon. The effects of the independent variables such as the time, power, pressure, and gas composition on the etch depth as well as the quality of the resulting etched surfaces were analyzed through a multiple linear regression approach. This provided second-order equations with an excellent ability to describe experimental results. The etching conditions for GaAs and AlGaAs were compared and optimum parameters for equal rate etching of GaAs/Al0.3Ga0.7As layers with straight walls were obtained. These were then sucessfully applied to the high-resolution structuring of multiple quantum well layers, and structures as small as 40 nm were etched. The addition of oxygen to the etch gas produced a high-quality etch for GaAs with &amp;gt;5:1 rate selectivity over Al0.3Ga0.7As.
<title>Highly damped exactly constrained mounting of an x-ray telescope</title> (1995)

Instruments and machines requiring very high stability should be isolated from their normally less stable environment. Exact constraint mounting using six, single-constraint flexures provides a stiff connection between the instrument and its environment while isolating the instrument from low frequency deformations of the environment, such as thermal expansion. Higher frequency disturbances, however, transfer through the flexures and excite vibration modes of the instrument. Traditionally, passive or active vibration isolation is employed to attenuate environmental disturbances reaching the instrument. However, strict alignment requirements for the instrument preclude the use of low-frequency isolation, unless active methods are used. Therefore, the solution is to provide damping in parallel with the flexures to reduce the vibration amplitudes of the instrument. Flexures concentrate strain energy in blades making them excellent candidates for damping treatments. A properly designed damping treatment across the flexures can provide as much as 8% to 10% viscous damping to the isolation modes and will also help attenuate the instrument vibration modes. Thus, through the use of six damped single-constraint flexures the instrument's requirements for stability, alignment, stress, and vibration may be met. An application of this approach will be employed on the Reflection Grating Array (RGA) for the X-ray Multi-mirror Mission for the European Space Agency. The RGA is an array of 200 diffraction gratings aligned to sub-micron and sub-arc-second tolerances relative to each other. This produces a coherent wavefront for spectrum analysis. The launch vehicle will be an Ariane 5 scheduled for 1998.
Pure-let deconvolution of 3D fluorescence microscopy images (2017)

Three-dimensional (3D) deconvolution microscopy is very effective in improving the quality of fluorescence microscopy images. In this work, we present an efficient approach for the deconvolution of 3D fluorescence microscopy images based on the recently developed PURE-LET algorithm. By combining multiple Wiener filtering and wavelet denoising, we parametrize the deconvolution process as a linear combination of elementary functions. Then the Poisson unbiased risk estimate (PURE) is used to obtain the optimal coefficients. The proposed approach is non-iterative and outperforms existing techniques (usually, variants of Richardson-Lucy algorithm) both in terms of computational efficiency and quality. We illustrate its effectiveness on both synthetic and real data.
Fourier-bessel field calculation and tuning of a CW annular array (2002)

A 1-D Fourier-Bessel series method for computing and tuning the linear lossless field of flat continuous wave (CW) annular arrays is given and discussed with both numerical simulation and experimental verification. The technique provides a new method for modelling and manipulating the propagated field by linking the quantized surface pressure profile to a set of limited diffraction Bessel beams propagating into the medium. &lt;br/&gt;In the limit, these become a known set of nondiffracting Bessel beams satisfying the lossless linear wave equation, which allow us to derive a linear matrix formulation for the field in terms of the ring pressures on the transducer surface. Tuning (beamforming) of the field then follows by formulating a least squares design with respect to the transducer ring pressures. Results are presented in the context of a 10-ring annular array operating at 2.5 MHz in water.
Treatment of theory uncertainties for Higgs measurements and searches at ATLAS (2019)

As the integrated luminosity recorded by the LHC experiments increases, systematic uncertainties play an ever more important role in Higgs boson measurements and searches. Several measurements are already limited by systematic uncertainties. Among these, theory uncertainties on the signal and background modeling play an important role. This talk discusses a few examples of analyses where theory uncertainties play an important role, and shows how these uncertainties are assessed and implemented in the analyses.
Joint Learning With BERT-GCN and Multi-Attention for Event Text Classification and Event Assignment (2022)

Government hotline is closely related to people’s lives and plays an important role in solving social problems and maintaining social stability in China. However, the event text of the hotline is inconsistent in length and unclear in elements, so it is a challenge for the operator to manually complete the assignment tasks of hotline event. To address these problems, we propose a joint learning method for event text classification and event assignment for Chinese government hotline. Firstly, graph convolution network (GCN) and BERT are used to process the event text respectively to obtain the corresponding representation vector. Then, the obtained two representation vectors are fused by the dynamic fusion gate to get fusion vector and classified the fusion vector through the text classification. Secondly, we use multi-attention mechanism to process the GCN result vector, BERT result vector and the “sanding” vector to obtain attentive “event-sanding” representation vector and calculate the corresponding department probability distribution. Finally, the historical prior knowledge based reorder model is used to sort the results of the “event-sanding” matching module and output the optimal assignment department of government hotline event. Experimental results show that our method can achieve better performance compared with several baseline approaches. The ablation experiments also demonstrate the validity of each proposed module in our model.
Miscellaneous organic NESHAP compliance for a new countermeasure flare production facility at the Milan Army Ammunition Plant (2004)

Abstract FR Countermeasures, Inc. (FRC), a division of Flight Refuelling Ltd. of the United Kingdom, has sited a countermeasure flare production facility at the Milan Army Ammunition Plant (MLAAP) in Milan, Tennessee. Franklin Engineering Group, Inc. (Franklin Engineering) worked in cooperation with FRC to develop an air permitting strategy that would allow expedited regulatory review and approval to meet an aggressive construction schedule. This strategy addressed eventual compliance with the 40 CFR, Subpart FFFF (Miscellaneous Organic NESHAP (MON) standard) by permitting the facility as a conditional major source to allow for construction, start‐up, and initial operation with eventual operation as a major source (i.e., Title V) at full processing rates. The facility was modeled after Flight Refuelling Ltd.'s North Stockbridge, U.K., manufacturing facility, with several important distinctions. First, the regulatory standards for air emissions from this type of facility in the United States, in combination with a higher production capacity, necessitated a higher level of control for hazardous air pollutants (HAPs). Additionally, FRC had to address increased volume of effluent water from the solvent recovery process and carbon regeneration process. Finally, this effluent water had to meet the Sewer Use Agreement, which required additional acetone removal prior to discharge to the sewer. The selection of an integrated air pollution control system to achieve these environmental objectives required special consideration of safety issues inherent to energetics manufacturing. After consideration of several air pollution control technologies, FRC and Franklin Engineering selected an activated carbon adsorption system for treatment of combined gases from two main batch sources: mixing and drying processes. This system will achieve greater than 95 percent recovery of HAPs from these processes, as required for regulatory purposes. Carbon beds are regenerated via steam stripping to yield two streams: recovered hydrocarbons and a recondensed aqueous stream. Recovered solvents are reused or sold. The aqueous stream is combined with water from the batch wash process and steam stripped for solvent recovery. Crucial to assuring safe operation of the air pollution control system was the utilization of a flame isolation valve with gas cartridge actuators to eliminate potential flame/deflagration passage between each process unit. © 2004 Wiley Periodicals, Inc.

The highest nuclearity metal oxime clusters: Ni14 and Ni12Na2 complexes from the use of 2-pyridinealdoximate and azide ligands (2007)

The reactions of 2-pyridinealdoxime [(py)CHNOH] with Ni(ClO4)(2).6H2O in the presence of NaOH and NaN3 have led to Ni(II)14 and Ni(II)12Na2 clusters; the Ni14 compound is the biggest metal oxime cluster discovered to date, as well as the largest Ni azide cluster.
Cytotoxicity of Au, ZnO and SiO2NPs usingin vitroassays with mussel hemocytes and gill cells: Relevance of size, shape and additives (2015)

Metal-bearing nanoparticles (NPs) possess unique physico-chemical characteristics that make them useful for an increasing number of industrial products and applications, but could also confer them a higher toxicity due to their higher reactivity compared to bulk forms of the same materials. There is a considerable interest in the use of in vitro techniques in environmentally relevant species, such as marine mussels, to evaluate NPs toxicity. In the present work, mussel hemocytes and gill cells were used to assess the potential toxic effects of Au, ZnO and SiO2 NPs with different sizes and shapes in parallel with their respective ionic and bulk forms and additives used in the NPs preparations. Cytotoxicity (neutral red and MTT assays) was screened at a wide range of concentrations, and LC50 values were calculated. Uptake of fluorescently labeled SIO2 NPs of 27 nm by hemocytes was also investigated. Au, ZnO and SiO2 NPs were less toxic than the corresponding ionic forms but more toxic than the bulk forms. ZnO NPs were the most toxic NPs tested which could be related with their capacity to release free ions. SiO2 NPs were not taken up by hemocytes and were not toxic to either hemocytes or gill cells. Size-dependent toxicity was found for Au NPs. Shape influenced the cytotoxicity of ZnO NPs. Finally, the presence of the additives Na-citrate and Ecodis P90 contributed to the toxicity of Au and ZnO NPs, respectively. As a general conclusion, solubility appears to play a key role in NPs toxicity to mussel cells.
