Flexible Filter Bank Based on an Improved Weighted Overlap-Add Algorithm for Processing Wide Bandwidth Radio Astronomy Signals (2015)

Wideband signals from a radio telescope have to be channelized for spectral observations or for dedispersion for pulsar observations. A polyphase filter bank is designed based on the improved weighted overlap-add (IWOLA) algorithm to achieve channelization. The IWOLA algorithm involves applying an equivalent Hilbert transform to the normal WOLA filter bank by shifting the center frequency of every sub-band by a half of the frequency bin, so that the IWOLA filter bank provides K independently output complex subbands instead of the usual K + 1 sub-bands, reducing the subsequent processing units by one set. Performance of the proposed IWOLA filter bank is analyzed by means of MATLAB simulations. We show how the IWOLA filter bank can be used for a two-stage, high-resolution spectrometer, with a much reduced consumption of FPGA on-chip block RAM.
The PedsQL in pediatric cerebral palsy: reliability, validity, and sensitivity of the Generic Core Scales and Cerebral Palsy Module (2007)

This investigation determined the measurement properties of the Pediatric Quality of Life Inventory (PedsQL) 3.0 Cerebral Palsy (CP) Module. PedsQL 4.0 Generic Core Scales and 3.0 CP Module were administered to 245 families. Mean age of the 134 males and 107 females was 8 years 1 month (SD 4y 4mo; range 2–18y). The sample included children with hemiplegia (n=55), diplegia (n=84), and quadriplegia (n=85). Twenty eight children had a Gross Motor Function Classification System classification at Level I, 40 at Level II, 86 at Level III, 43 at Level IV, and 37 at Level V. Reliability was demonstrated for the PedsQL 4.0 (α=0.86 child, 0.89 parent) and CP Module (α=0.79 child, 0.91 parent). The PedsQL 4.0 distinguished between healthy children and children with CP. Construct validity of the CP Module was supported. Sensitivity of the PedsQL was demonstrated among children with different diagnostic categories and gross motor function.
A multidisciplinary approach to leg ulcer management in primary care (2001)

The majority of management of venous leg ulcers takes place in the community, where it plays a major role in the workload of the district nursing service. District nurses are generally able to manage uncomplicated venous leg ulcers effectively, but may face difficulties when faced with ulcers with more complex aetiology. This article describes the formation, structure and operation of a multidisciplinary team in Salford which has had a significant impact on the management of this difficult problem. In doing so, it raises some important points for other trusts to consider when establishing a dedicated leg-ulcer service.
Ostrom and the lawyers: The impact of Governing the Commons on the American legal academy (2011)

<span style="font-size: 12pt; font-family: "Times New Roman"; mso-bidi-font-size: 10.0pt; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;">American legal academics began to cite Elinor Ostrom's <em>Governing the Commons </em>(GC) shortly after its 1990 publication, with citations peaking in the mid-2000s and with signs of a new peak in 2010 in the wake of Ostrom's Nobel Prize in Economics. The legal scholars most interested in GC have worked in three areas: general property theory, environmental and natural resource law, and since the mid-1990s, intellectual property. In all those areas legal scholars have found GC and its many examples a strong source of support for the proposition that people can cooperate to overcome common pool resource issues, managing resources through informal norms rather than either individual property or coercive government. Legal academics have also been at least mildly critical of GC, however. A number have tried to balance the attractive features of GC's governance model - stability and sustainability - with more standard legal models favoring toward open markets, fluid change and egalitarianism.</span>

Functional Regeneration of Chronically Injured Sensory Afferents into Adult Spinal Cord after Neurotrophin Gene Therapy (2001)

Lesioned axons within the dorsal roots fail to regenerate through the peripheral nerve transition zone and into the spinal cord. This regenerative failure leads to a persistent loss of sensory function. To induce axonal growth across this barrier, we used recombinant adenovirus to express fibroblast growth factor-2 (FGF2), nerve growth factor (NGF), L1 cell adhesion molecule (L1), or beta-galactosidase (LacZ) within the endogenous glia of the dorsal spinal cord 16 d after injury. Expression of either FGF2 or NGF, but not L1 or LacZ, induced robust axonal regeneration into normal as well as ectopic locations within the dorsal spinal cord. This regeneration led to near-normal recovery of thermal sensory function. Functional recovery and the majority of regenerating axons within the dorsal horn disappeared with recutting of the sensory roots. Injections of adenovirus encoding NGF, but not FGF2, also resulted in extensive sprouting of noninjured sensory axons, which we previously demonstrated could cause hyperalgesia and chronic pain. Thus, neurotrophic factor gene therapy administered as late as 16 d after injury may serve as a useful treatment to elicit recovery after dorsal root avulsion; however, the choice of neurotrophin is important to induce selective regeneration of damaged axons.

A Key Exchange Method for Intelligent Electronic Devices in Distribution Automation (2010)

The use of communication networks and intelligent electronic devices (IEDs) for power systems is becoming more common and more necessary. Changes in the power system structure, changes in requirements and the necessity to have easy access to accurate data have led to the need for communication systems. Due to these changes, communication systems with IEDs in power companies expose the safety-critical power companies' network to the multitude security problems of communication networks. This paper proposes a method called multiple channel secure acknowledging multicast, which merges the tasks of acknowledgment and key changes in a simple and direct manner to make exposed IEDs more secure in distribution automation.
A comparison of service quality in the banking industry (2005)

Purpose To analyze and compare service quality in the commercial banking sector of a small island economy – Cyprus and to investigate the relationship between overall bank customer satisfaction in the Turkish‐ and Greek‐speaking areas of Cyprus and positive word‐of‐mouth about their banks. Design/methodology/approach A total of 268 commercial bank customers responded to a Greek and Turkish translated version of the SERVQUAL instrument. After descriptive and factor analysis, multivariate regression was used to estimate the impact of service quality dimensions on overall customer satisfaction and word of mouth. Findings The responsiveness dimension failed to load and thus the SERVQUAL scale proved to be of a four‐dimensional structure in this study. Research results revealed that the expectations of bank customers in both areas were not met and that the largest gap was found in the empathy dimension. The assurance dimension had the largest influence on customer satisfaction and overall satisfaction of bank customers in both areas of Cyprus had a positive effect on their word‐of‐mouth. Research limitations/implications There were some difficulties in conducting interviews in the Greek‐speaking area of Cyprus and this may have limited the potential sample size. Future research could test the generalizability of findings in other small island economies and look at how the service is delivered by frontline employees. Practical implications Helps banks in both areas of Cyprus to redefine their corporate image to one that is customer‐focused and driven by service quality. Findings are also significant for the Turkish‐speaking area which is not at the same level of economic development as its neighbours in the south and needs to restructure its banking system before accession to the EU. Originality/value This study investigates service quality in a small island economy. There is disparity in the banking sector of a divided Cyprus, where banks in the South have undergone significant restructuring before EU accession and banks in the North are affected by the economic crisis and need to restructure if they want to join the EU.
Architectural and multiprocessor design verification of the PowerPC 604 data cache (2002)

The PowerPC 604 microprocessor has high performance 32-bit implementation, which is optimized to produce compact code while adhering to RISC philosophy. The PowerPC 604 microprocessor can sustain a maximum issue rate of 4 instructions per cycle. The data cache of the 604 is a 16 KB four-way set-associative non-blocking cache which contains MESI states (M: Modified, E: Exclusive-unmodified, S: Shared, I: Invalid), a reservation bit with its reservation address register, an independent snoop port, WIMG (W: cache write policy, I: cacheability, M: coherency mode, G: protection against speculative access) support logic, and parity bits. The 604 has an on-chip phase-locked loop to provide different Processor/Bus clock ratios to simplify the system design while using a 100 MHz processor clock. The data cache to BIU (Bus Interface Unit) interface can handle different Processor/Bus clock ratios. The architecture and multiprocessor verification for the PowerPC 604 data cache systematically checks the data cache architecture, logic, and implementation correctness and provides the assurance that the PowerPC 604 microprocessor's aggressive hardware and software implementation is carried out correctly in the uniprocessor and multiprocessor environment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Outlier Detection Using the Multiobjective Genetic Algorithm (2020)

Since almost all datasets may be affected by the presence of anomalies which may skew the interpretation of data, outlier detection has become a crucial element of many datamining applications. Despite the fact that several methods of outlier detection have been proposed in the literature, there is still a need to look for new, more effective ones. This paper presents a new approach to outlier identification based on genetic algorithms. The study evaluates the performance and examines the features of several multiobjective genetic algorithms.
<title>Motion segmentation and cloud tracking on noisy infrared image sequences</title> (1998)

Aerial surveillance is an issue of key importance for warship protection. In addition to radar systems, infrared surveillance sensors represent an interesting alternative for remote observation. In this paper, we study such a system and an original approach to the tracking of complex cloudy patterns in noisy infrared image sequences is proposed. We have paid particular attention to robustness with regards to perturbations likely to occur (noise, 'lining effects' . . .). Our approach relies on robust parametric motion estimation and an original regularization scheme allows to handle with the appearance and the disappearance of objects in the scene. Numerous experiments performed on outdoor infrared image sequences underline the efficiency of the proposed method.
Diesel Aftertreatment Modeling:  A Systems Approach to NO<i><sub>x</sub></i> Control (2007)

Stringent North American emission regulations present several challenges for lean-burn diesel vehicles that offer significant fuel economy advantages over gasoline vehicles. This article presents a useful systems approach to developing robust models and combining them to analyze diesel aftertreatment (AT) technologies: (1) the diesel oxidation catalyst (DOC) that oxidizes carbon monoxide (CO), unburned hydrocarbons (HCs), and nitric oxide (NO), and stores HCs and (2) the urea-based selective catalytic reduction (SCR) catalyst that hydrolyzes aqueous urea to ammonia (NH3), which, in turn, reduces nitrogen oxides (NOx). The DOC and SCR models integrate information from multiple sourcesdetailed thermal balances, laboratory performance data, phenomenological descriptions of adsorption and desorption in the catalyst, and experience-based correlationsusing optimization and statistical tools. The DOC model predicts cumulative HC and CO tailpipe vehicle emissions as well as DOC NOx outlet composition (NO vs NO2). The SCR model uses the exotherm and NO2 information from the DOC model to predict NOx conversion and NH3 slip. System-level analyses that have resulted in important insights are highlighted using case studies, including (1) extrapolation of the downstream injection exotherm vehicle data for a fresh DOC to an aged DOC; (2) analysis of the effects of NO2 produced in the DOC, SCR aging conditions, and NH3 storage capacity on the NOx reduction performance of the SCR on a 6000-lb light-duty truck, and (3) development of urea injection strategies based on a tradeoff between NOx reduction and NH3 slip.
Structure and Properties of Cubic Silicon Carbide (100) Surfaces: A Review (1997)

The many uses for SiC in electronics have been well documented [1 to 3]. Many of these applications, as well as the growth of the material itself, are critically dependent on the structural and electronic properties of surfaces and interfaces. From a basic perspective, SiC is unique in that it is a IV–IV compound semiconductor. As such it forms a “bridge” between the elemental column-IV materials Si and Ge and the III–V's GaN, GaAs, etc. These considerations have led to many experimental and theoretical studies of SiC surfaces, a significant fraction of which have appeared in the past few years. This paper reviews recent experimental results for clean, ordered and well-characterized (100) surfaces. Cubic (111) surfaces are excluded since they are more properly discussed [4] together with those of hexagonal SiC(0001) and (0001-), to which they are essentially identical. There have, to date, been no experimental data reported for SiC(110) surfaces. Work up to about mid-1993 has already been briefly reviewed [5]. A discussion of metal/SiC interfaces was also given [5], but more recent work will be omitted. Mention is also made here of theoretical results, which are discussed extensively elsewhere [6].

The variable scan schedule method would be useful to reduce radiation dose while maintaining the accuracy of CT perfusion (CTP) parameters.
Effects of thromboxane synthetase inhibition on immune complex glomerulonephritis. (1991)

To determine the role of thromboxane A2 in the pathogenesis of experimentally induced immune complex glomerulonephritis, 12 concanavalin A-immunized Beagles were infused with 1 mg of concanavalin A via each renal artery and treated twice daily for 8 days with either 30 mg of CGS 12970/kg, PO, a specific thromboxane synthetase inhibitor, or placebo. The effect of treatment was assessed by measuring endogenous creatinine clearance and urine protein and eicosanoid excretion, and by evaluating changes in glomerular morphometric characteristics. On postinfusion day 8, urine protein, thromboxane B2, and 11-dehydro-thromboxane B2 excretion, glomerular epithelial crescent formation, and glomerular cell proliferation in the CGS 12970-treated dogs were significantly decreased when compared with values in the placebo-treated group. Differences were not observed in endogenous creatinine clearance, urine prostaglandin E2 and 6-keto-prostaglandin F1 alpha excretion, or glomerular polymorphonuclear leukocyte infiltration between groups in this study. These findings suggest thromboxane A2 has a role in the development of immune complex glomerulonephritis and that thromboxane synthetase inhibition may be beneficial in attenuating some of the functional and histological changes associated with immune complex glomerulonephritis.
Die Bildung chiraler Mono(η <sup>5</sup> ‐cyclopentadienyl)zirconium(II)‐Komplexe (1985)

Die Umsetzung von CpZrCl3 (6) mit Allylmagnesiumchlorid liefert Tris(allyl)(η5-cyclopentadienyl)zirconium (7a). Durch eine Komproportionierung mit 6 wird daraus CpZr(allyl)Cl2 (9a) zugänglich, dessen Reaktion mit „Butadien-Magnesium”︁ das (η3-Allyl)(η4-butadien)(η5-cyclopentadienyl)zirconium (12a) in guter Gesamtausbeute ergibt. 12a zeigt dynamische NMR-Spektren. Es wird daraus eine Aktivierungsbarriere der Automerisierung des Allylliganden von ΔG = 19 kcal/mol abgeleitet. Die Photolyse von 12a bei tiefer Temperatur liefert 13a. Nach den NMR-Spektren, insbesondere den 1H-NMR-NOE-Differenzspektren, unterscheiden sich die Isomeren 12a und 13a durch die relative Anordnung der drei π-Liganden zueinander. Die Struktur beider Verbindungen leitet sich von einer quadratisch-pyramidalen Geometrie ab. In 12a öffnen sich beide offenkettigen 4π-Liganden zur apikalen Cp-Gruppierung, in 13a öffnen sie sich zur Basis des pyramidalen Gerüstes. 13a lagert sich in einer thermisch induzierten Reaktion zu 12a um (ΔG = 22 kcal/mol). Zwei chirale Metallkomplex-Systeme analoger Struktur, (η4-Butadien)(η5 -cyclopentadienyl)(η3-1-methylallyl)zirconium (12 b/13 b) und (η3-Allyl)-(η5-cyclopentadienyl)(η4-isopren) zirconium (12c/13c), wurden durch analoge Reaktionsfolgen hergestellt. Die Aktivierungsbarrieren der degenerierten Allylumlagerung wie der Isomerisierung sind in der gleichen Größenordnung wie beim Stammsystem 12a/13a. Formation of Chiral Mono(η5-cyclopentadienyl)zirconium(II) Complexes Treatment of CpZrCl3 (6) with allylmagnesium chloride yields tris(allyl)(η5-cyclopentadienyl)-zirconium (7a). Its comproportionation reaction with 6 makes CpZr(allyl)Cl2 (9a) available. The reaction of 9a with “butadiene-magnesium” proceeds to (η3-allyl)(η4-butadiene)(η5-cyclopentadienyl) zirconium (12a) in a high overall yield. 12a exhibits dynamic NMR spectra. From their analysis an activation barrier of ΔG = 19 kcal/mol is derived for the automerization reaction of the allyl ligand. Photolysis of 12a at low temperature yields 13a. According to the NMR spectra, especially the 1H NMR NOE difference spectra, the isomers 12a and 13a are distinguished by the relative arrangement of the three π-ligands. The structure of both compounds is derived from a square-pyramidal geometry. In 12a both open-chain 4π-ligands open themselves in a direction towards the apical Cp-moiety, in 13a their open sides point to the basis of the pyramidal skeleton. 13a rearranges to 12a in a thermally induced reaction (ΔG = 22 kcal/mol). Two chiral transition metal complex systems of analogous structures, (η4-butadiene)(η5-cyclopentadienyl)(η3-1 -methylallyl)zirconium (12b/13b) and (η3-allyl(η5-cyclopentadienyl)(η4isoprene)-zirconium (12c/13c), have been obtained by similar reaction sequences. The activation barriers of the degenerate allyl rearrangement as well as the isomerization reaction are of the same order of magnitude as found for their parent system 12a/13a.
Magnetic force‐based mesenchymal stem cell expansion using antibody‐conjugated magnetoliposomes (2005)

Recently, there has been an accumulation of evidence indicating that human mesenchymal stem cells (MSCs, multipotent cells resident in the bone marrow) are useful for autologous cell transplantation. However, only small numbers of MSCs have been obtained in bone marrow aspirates. We have developed a novel methodology for enriching and proliferating MSCs from bone marrow aspirates using antibody-conjugated magnetoliposomes (AMLs). The AMLs are liposomes conjugated to anti-CD105 antibody (immunoliposomes) and contain magnetite nanoparticles (diameter 10 nm). In the present study, the AMLs were added to a small volume (1 mL) of human bone marrow aspirate. After a 1-h incubation period, the bone marrow aspirates containing AMLs were seeded into 10-cm tissue culture dishes, and a disk-shaped magnet (diameter 2.2 cm; height 1 cm; 4000 Gauss) was positioned under the dish to enrich MSCs by magnetic force. The MSCs proliferated, forming colonies at the site where the magnet was positioned. In contrast, no colonies and very few viable cells were observed in ordinary culture based on plastic-adherent tendencies of cells without use of AMLs. These results suggest that this AML culture method can rapidly and efficiently expand a small number of MSCs into numbers suitable for clinical application.
Mass marker for the AEI mass spectrometer MS2H (1967)

In order to simplify the calibration of mass spectra, a mass marker has been designed for the AEI mass spectrometer MS2H which, with slight modifications, can be applied to any other magnetically scanned spectrometer. During the scanning of the spectrometer, the apparatus operates the marker pen of the recorder so that calibration markings are registered during recording of the spectrum. The marker is based on accurate determination of the current through the deflection magnet which is used for the magnetic scanning in the spectrometer. The influence of the hysteresis effect is eliminated by automatic programming of the magnet current before each measurement. When the marker is used with an AEI mass spectrometer MS2H, spectra can be calibrated at every fifth m/e in the range 60-535 m/e, provided the ion-accelerating voltage is 2000 v. The accuracy is to 0.3 m/e.
