RELSYN: a tool for synthesis of reliable application specific multiprocessors (1996)

In this paper, an integrated approach for automatically synthesizing application specific, reliable multiprocessor systems is described. The characteristics of the candidate application task and the failure rates/performance/cost of the processors (and buses) are combined to evolve an optimal reliable multiprocessor system tuned to the application task. Such an integrated approach yields (i) an application specific multiprocessor architecture, and (ii) a reliability-oriented mapping/schedule of sub tasks in the application task graph to processors.
Estimation of Noise Power Radiated from Gear Blanks. 6th Report. Estimation and Experiment of Sound Power Radiated from a Circular Plated with a Solid Shaft Subjected to a Three Dimensional Load. (1993)

The overall aim of this research is to establish an effective method for accurately estimating the noise power radiating from gear blanks. For this purpose, the basic theory for estimating the frequency response of radiated sound power was proposed in previous papers, and was applied to a circular plate with a solid shaft subjected to an axial load, in which the circular plate was a simple model of gear blanks. The basic theory was extended in previous papers to the circular plates excited three-dimensionally similar to that for helical gears. In this paper the basic theory has been further extended to include the rigid-body modes of vibration as well as the natural modes of flexural vibration of the circular plates. Consequently, the estimation of radiated sound power was much improved in a low-frequency range below 3 kHz, where the rigid-body modes existed.
Atomic Layer Deposition of Metal Tellurides and Selenides Using Alkylsilyl Compounds of Tellurium and Selenium (2009)

Atomic layer deposition (ALD) of metal selenide and telluride thin films has been limited because of a lack of precursors that would at the same time be safe and exhibit high reactivity as required in ALD. Yet there are many important metal selenide and telluride thin film materials whose deposition by ALD might be beneficial, for example, CuInSe2 for solar cells and Ge2Sb2Te5 for phase-change random-access memories. Especially in the latter case highly conformal deposition offered by ALD is essential for high storage density. By now, ALD of germanium antimony telluride (GST) has been attempted only using plasma-assisted processes owing to the lack of appropriate tellurium precursors. In this paper we make a breakthrough in the development of new ALD precursors for tellurium and selenium. Compounds with a general formula (R3Si)2Te and (R3Si)2Se react with various metal halides forming the corresponding metal tellurides and selenides. As an example, we show that Sb2Te3, GeTe, and GST films can be deposited by ALD using (Et3Si)2Te, SbCl3, and GeCl2 x C4H8O2 compounds as precursors. All three precursors exhibit a typical saturative ALD growth behavior and GST films prepared at 90 degrees C show excellent conformality on a high aspect-ratio trench structure.
The Effect of Planting Techniques on Arid Ecosystems in the Northern Negev (2013)

Forestation is a widely accepted way to combat desertification. This approach can have tremendous beneficial effects on soil and environment. The United Nations Food and Agriculture Organization recommended Acacia victoriae for rehabilitation of degraded arid environments. For that purpose areas in the Northern Negev were planted with Acacia victoriae in the period of 1990–1993. The planting techniques were: sparse plantings (Contour trenching and Savanna), and dense planting of woodland. We divided each of those treatments into planted and control plots. In the plots planted by contour trenching the values of annual biomass per area, nutrient and Soil Organic Carbon (SOC) contents underneath the tree's canopies were the lowest, while those values in the planted savanna and woodland plots were significantly higher. Contour trenching also harmed the soil by causing erosion, and decreasing the soils water holding capacity. Therefore, Woodland and Savanna plantings should be preferred over contour trenching in arid areas.
Photovoltaic characterization of hybrid solar cells using surface modified TiO2nanoparticles and poly(3-hexyl)thiophene (2008)

We report on the photovoltaic performance of bulk heterojunction solar cells using novel nanoparticles of 6-palmitate ascorbic acid surface modified TiO(2) as an electron acceptor embedded into the donor poly(3-hexyl)thiophene (P3HT) matrix. Devices were fabricated by using P3HT with varying amounts of red TiO(2) nanoparticles (1:1, 1:2, 1:3 w-w ratio). The devices were characterized by measuring current-voltage characteristics under simulated AM 1.5 conditions. Incident photon to current efficiency (IPCE) was spectrally resolved. The nanoscale morphology of such organic/inorganic hybrid blends was also investigated using atomic force microscopy (AFM).
THREE DIMENSIONAL SMOOTHING TECHNIQUES USING QUATERNIONS APPLIED TO GAIT (2008)

The purpose of this study was to implement a three-dimensional (3D) technique for smoothing gait analysis data. Three dimensional smoothing is problematic as it relies on one-dimensional smoothing techniques that are ill-posed to preserve the integrity of the real, raw data. Since Davis et al, (1991) method many researchers (e.g. Baker, 2006) have emphasized the problems of three dimensional gait analysis.
An Improved K-means Algorithm for Document Clustering (2015)

K-Means algorithm has a major shortcoming of high dimensional and sparse data. So the traditional measurement of the distance can't deal with the data effectively. Motivated by this, this paper proposed a K-Means algorithm based on Sim Hash. After preprocessing of the text, Sim Hash is used to calculate the feature vectors extracted, and then the fingerprint of each text is obtained. Sim Hash not only reduces the dimension of the text, but also directly calculates the Hamming distance between the fingerprints as the vector distance. According to the Hamming distance, it can judge which clustering the data is belongs to. Experimental result shows that the algorithm guarantees the quality of the clustering, and greatly reduces the speed of K-means clustering algorithm.
Regulatory Mechanisms in Carbohydrate Metabolism (1973)

Abstract 1. Aerobic lactic acid production in ascites tumor cells was not inhibited by rutamycin, indicating that the ADP and Pi required to sustain glycolysis were not supplied by mitochondrial ATPase. In contrast, the marked stimulation of lactic acid production induced by dinitrophenol was eliminated by rutamycin. 2. Parallel studies on the inhibition of lactic acid production and monovalent cation transport by ouabain revealed a close relationship between the two processes. About 1 mole of lactic acid was formed per mole of monovalent cation translocated. 3. The depression of glycolysis by ouabain was shown to result from the inhibition of (Na+, K+)-ATPase rather than from a lack of K+ as indicated by the high rate of aerobic glycolysis induced by dinitrophenol in the presence of ouabain. In the absence of dinitrophenol both Na+ and K+ were required for optimal glycolysis. 4. Evidence for a sodium-linked transport of Pi was obtained. 5. Dextran sulfate and other related compounds were found to have a profound effect on the permeability properties of ascites tumor cells. Glycolysis was markedly inhibited by dextran sulfate, and loss of intracellular ions, adenine nucleotides, and protein was demonstrated. In the presence of excess adenine nucleotides and Pi in the medium, dextran sulfate did not inhibit; in fact, it consistently stimulated glycolysis. It was shown that under these conditions AMP entered the cells and was converted into ATP. 6. The regulation of glycolysis in tumor cells by energy-linked ion transport is discussed.

Prediction of Transition-State Scaling Relationships and Universal Transition-State Vibrational and Entropic Correlations for Dehydrogenations (2021)

Linear scaling relationships (LSRs) and Brønsted–Evans–Polanyi (BEP) or transition-state scaling (TSS) relations aid with the prediction of electronic energies. However, temperature effects and pre-exponentials are often taken as constants across metal surfaces or a homologous series. Vibrational scaling relationships (VSRs) offer a way to determine such parameters. Transition-state VSRs (TSVSRs) between local minima and transition states of AHX (A = C, N, O) surface diffusions correlate with BEP relations and broaden to thermochemical property scaling. Using density functional theory, we extend TSVSRs to AHX dehydrogenation reactions on transition-metal surfaces, relating vibrational modes of local minima to transition states. We first predict the slopes of the TSS relations by incorporating bond angles using the Slater–Koster structure factors and hybridization through crystal orbital overlap population analysis and energy overlap integrals between adsorbates and metal surfaces. Additionally, we uncover universal thermochemical property scaling, enabling the estimation of entropies and temperature corrections to enthalpies across a homologous series. We demonstrate both significant vibrational corrections in reactions with low intrinsic electronic barriers and considerable variation in the pre-exponential of a simple dehydrogenation reaction across metals and AHX adsorbates.
Mutational and Structural Studies of the Diisopropylfluorophosphatase from Loligo vulgaris Shed New Light on the Catalytic Mechanism of the Enzyme (2005)

The active site, the substrate binding site, and the metal binding sites of the diisopropylfluorophosphatase (DFPase) from Loligo vulgaris have been modified by means of site-directed mutagenesis to improve our understanding of the reaction mechanism. Enzymatic characterization of mutants located in the major groove of the substrate binding pocket indicates that large hydrophobic side chains at these positions are favorable for substrate turnover. Moreover, the active site residue His287 proved to be beneficial, but not essential, for DFP hydrolysis. In most cases, hydrophobic side chains at position 287 led to significant catalytic activities although reduced relative to the wild-type enzyme. With respect to the Ca-1 binding site, where catalysis occurs, various mutants indicated that the net charge at this calcium-binding site as well as the relative positions of the charged calcium ligands is crucial for catalytic activity. The importance of the electrostatic potential at the active site was furthermore revealed by various mutations of residues lining the interior of the central water-filled tunnel, which traverses the entire protein structure. In this respect, the structural features of residue His181, which is located at the opposite end of the DFPase tunnel relative to the active site, were characterized extensively. It was concluded that a tunnel-spanning hydrogen bond network, which includes a large number of apparently slow exchanging water molecules, relays any modifications in the electrostatics of the system to the active site, thus affecting the catalytic reactivity of the enzyme.
Supercritical fluid chromatography for lipid analysis in foodstuffs (2016)

The task of lipid analysis has always challenged separation scientists, and new techniques in chromatography were often developed for the separation of lipids; however, no single technique or methodology is yet capable of affording a comprehensive screening of all lipid species and classes. This review acquaints the role of supercritical fluid chromatography within the field of lipid analysis, from the early developed capillary separations based on pure CO<sub>2</sub> , to the most recent techniques employing packed columns under subcritical conditions, including the niche multidimensional techniques using supercritical fluids in at least one of the separation dimensions. A short history of supercritical fluid chromatography will be introduced first, from its early popularity in the late 1980s, to the sudden fall and oblivion until the last decade, experiencing a regain of interest within the chromatographic community. Afterwards, the subject of lipid nomenclature and classification will be briefly dealt with, before discussing the main applications of supercritical fluid chromatography for food analysis, according to the specific class of lipids.
Evaluation of the Distribution of Paclitaxel After Application of a Paclitaxel-Coated Balloon in the Rabbit Urethra (2018)

Introduction: Urethral strictures are a common urologic problem that could require complex reconstructive procedures. Urethral dilatation represents a frequent practiced intervention associated with high recurrence rates. Drug-coated percutaneous angioplasty balloons (DCBs) with cytostatic drugs have been effectively used for the prevention of vascular restenosis after balloon dilatation. To reduce restenosis rates of urethral dilatation, these balloons could be used in the urethra. Nevertheless, the urothelium is different than the endothelium and these drugs may not be distributed to the outer layers of the urethra. Thus, an experiment was performed to evaluate the distribution of paclitaxel (PTX) in the rabbit urethra after the inflation of a PTX-coated balloon (PCB). Materials and Methods: Eleven rabbits underwent dilatation of the posterior urethra with common endoscopic balloons after urethrography. Nine of these rabbits were additionally treated with PCB. The urethras of the two control animals were removed along with three more dilated with PCB urethras immediately after the dilatation. The remaining of the urethras were removed after 24 (n = 3) and 48 hours (n = 3). The posterior segments of the urethras were evaluated with hematoxylin and eosin staining as well as with immunohistochemistry with polyclonal anti-PTX antibody. Results: The two control specimens showed denudation of the urothelium after balloon dilatations and no PTX was observed. All specimens from dilated PCB urethras showed distribution of PTX to all layers of the urethra. The specimens that were immediately removed exhibited denudation of the urothelium without any inflammation. The specimens removed at 24 and 48 hours showed mild acute inflammation. Conclusion: PTX was distributed to the urothelial, submucosal, and smooth muscle layers of the normal rabbit urethra immediately after dilatation with a DCB. PTX and mild inflammation were present at the site 24 and 48 hours after the dilatation.
Copper-ATSM as a Treatment for ALS: Support from Mutant SOD1 Models and Beyond (2020)

The blood-brain barrier permeant, copper-containing compound, Cu<sup>II</sup>(atsm), has successfully progressed from fundamental research outcomes in the laboratory through to phase 2/3 clinical assessment in patients with the highly aggressive and fatal neurodegenerative condition of amyotrophic lateral sclerosis (ALS). The most compelling outcomes to date to indicate potential for disease-modification have come from pre-clinical studies utilising mouse models that involve transgenic expression of mutated superoxide dismutase 1 (SOD1). Mutant SOD1 mice provide a very robust mammalian model of ALS with high validity, but mutations in SOD1 account for only a small percentage of ALS cases in the clinic, with the preponderant amount of cases being sporadic and of unknown aetiology. As per other putative drugs for ALS developed and tested primarily in mutant SOD1 mice, this raises important questions about the pertinence of Cu<sup>II</sup>(atsm) to broader clinical translation. This review highlights some of the challenges associated with the clinical translation of new treatment options for ALS. It then provides a brief account of pre-clinical outcomes for Cu<sup>II</sup>(atsm) in SOD1 mouse models of ALS, followed by an outline of additional studies which report positive outcomes for Cu<sup>II</sup>(atsm) when assessed in cell and mouse models of neurodegeneration which do not involve mutant SOD1. Clinical evidence for Cu<sup>II</sup>(atsm) selectively targeting affected regions of the CNS in patients is also presented. Overall, this review summarises the existing evidence which indicates why clinical relevance of Cu<sup>II</sup>(atsm) likely extends beyond the context of cases of ALS caused by mutant SOD1.
d2, d3, and d4 M3C2 Transition Metal Carbides (MXenes) as Catalysts for CO2 Conversion into Hydrocarbon Fuels: A Mechanistic and Pre-dictive DFT Study (2016)

The functioning of 2D d2, d3, and d4 transition metal carbides as CO2 conversion catalysts has been proved by well resolved density functional theory (DFT) and DFT+U theoretical calculations. Whilst MXenes from the d2 series (M = Ti, Zr, and Hf) have demonstrated active behaviors for the capture of CO2, the V3C2, Nb3C2, Cr3C2, and Mo3C2 materials exhibit the most promising results for their application in the selective CO2 conversion into CH4, with limiting reaction energies of 1.55, 1.75, 0.69, and 1.24 eV, respectively, at DFT+U computational level plus explicit DFT-D3 dispersion corrections, and specially highlighting the role of Cr3C2 due to its theoretically predicted low over potential. Moreover, important features have been predicted during the first hydrogenation step towards the formation of the OCHO and HOCO radical species, exhibiting spontaneous reaction energies in the OCHO obtaining for such promising carbides from the d3 and d4 groups. Our re-sults provide novel insights in the computer-aided searching of high performance catalysts and the understanding of reaction mech-anisms for CO2. Finally, it is hypothesized that the capture of CO2 along the early step of the reaction is spontaneously produced without pass from a physisorbed state, being the strength of such capture larger than the computed binding energies for the chemi-sorption of H2O, offering encouraging perspectives for the experimental testing of our materials in water environment
Towards green information retrieval: studying the suitability of queueing theory in reducing power consumption (2014)

Heterotopic ossification (HO) is a pathological process where bone forms in connective tissues such as skeletal muscle. Previous studies have suggested that muscle-resident non-myogenic mesenchymal progenitors are the likely source of osteoblasts and chondrocytes in HO. However, the previously identified markers of muscle-resident osteoprogenitors label up to half the osteoblasts within heterotopic lesions, suggesting other cell populations are involved. We have identified alpha smooth muscle actin (αSMA) as a marker of osteoprogenitor cells in bone and periodontium, and of osteo-chondro progenitors in the periosteum during fracture healing. We therefore utilized a lineage tracing approach to evaluate whether αSMACreERT2 identifies osteoprogenitors in the muscle. We show that in the muscle, αSMACreERT2 labels both perivascular cells, and satellite cells. αSMACre-labeled cells undergo osteogenic differentiation in vitro and form osteoblasts and chondrocytes in BMP2-induced HO in vivo. In contrast, Pax7CreERT2-labeled muscle satellite cells were restricted to myogenic differentiation in vitro, and rarely contributed to HO in vivo. Our data indicate that αSMACreERT2 labels a large proportion of osteoprogenitors in skeletal muscle, and therefore represents another marker of muscle-resident cells with osteogenic potential under HO-inducing stimulus. In contrast, muscle satellite cells make minimal contribution to bone formation in vivo.
Roadmap for 10 Gbit/in/sup 2/ media: challenges (1992)

The authors examine the requirements for 10 Gb/in/sup 2/ media, taking guidance from a recording model and known trends in high-performance media. They apply a read/write model to examining the media properties required for this density in a practical drive application. They find that the required magnetic and microstructural properties with the concomitant noise and supermagnetic limits demand significant improvements over existing media, to the extent that revolutionary improvements will likely be required.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

The bandwidth performance of a two-element adaptive array with tapped delay-line processing (1988)

The bandwidth performance of a two-element adaptive array with a tapped delay line behind each element is examined. It is shown how the number of taps and the delay between taps affect the bandwidth performance of the array. An array with two weights and one delay behind each element is found to yield optimal performance (equal to that obtained with continuous-wave interference) for any value of intertap delay between zero and T/sub 90//B, where T/sub 90/ is a quarter-wavelength delay time and B is the fractional signal bandwidth. Delays less that T/sub 90/ yield optimal performance but result in large array weights. Delays larger than T/sub 90//B yield suboptimal signal-to-interference-plus-noise ratio when each element has only two weights. For delays between T/sub 90//B and 4T/sub 90//B, the performance is suboptimal with only two taps but approaches the optimal if more taps are added to each element. Delays larger than T/sub 90//B result in suboptimal performance regardless of the number of taps used.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Power devices loading in multilevel converters for 10 MW wind turbines (2011)

Several promising multilevel converter solutions for 10 MW wind turbines using permanent magnet synchronous generators are proposed, designed and compared both with one-stage gear-box drive and direct drive systems. The current and loss distributions, as well as the utilization of power devices in each converter are analyzed based on simulation results. Finally, the total loss and efficiency comparison are given. It is concluded that five-level and three-level H-bridge topologies show higher efficiency either in the power conversion or in the device utilization compared to the three-level Neutral-Point-Clamped topology with both the direct-drive and one-stage gear box drive systems.
On work in progress optimisation (2003)

In this paper, we investigate how to best optimise the level of work in progress (WIP) in a real world factory. Using a simulation model of the factory, we show that an optimum level of WIP can be attained. By systematically varying the maximum allowable level of WIP within different model runs, results show that the throughput reaches a high level very quickly and then tapers off. The production lead times, in contrast, begin at relatively low levels and increase after the optimum WIP level has been reached.
