Control Adaptativo Fraccionario Optimizado por Algoritmos Genéticos, Aplicado a Reguladores Automáticos de Voltaje (2016)

The technique Fractional Order Model Reference Adaptive Control (FOMRAC) applied to an Automatic Voltage Regulator (AVR) is presented in this paper. The work is focused on tuning the adaptive gains and the derivation order of the adaptive laws of the FOMRAC, determined through the minimization of a criterion function defined for the simplified model of the AVR, by means of the genetic algorithm (GA) optimization technique. Based on the criterion function proposed by other authors a simulated comparative study is performed, comparing the proposed methodology with the integer order PID control reported in (Zamani et al., 2009). It is shown that the FOMRAC with parameters optimized by GA provides better results in terms of robustness under parameters variations of the system under control and improvements in the convergence speed of the control error.
Deinterlacing of video signals using nonlinear interpolation with simple motion compensation (2005)

A new algorithm to convert interlaced video sequences to a progressive format is proposed. The algorithm is based on motion detection and adaptive weighted median filtering. The weights are adapted to emphasize temporal information in stationary areas and spatial information in moving areas. Compensation of commonly occuring horizontal motion is used to improve the performance without adding the extra complexity of full motion compensation. A novel improvement to direction dependent processing is used to enhance the interpolation result on diagonal edges. The main motivation for this work has been the production of high quality still images from interlaced sources for, e.g., printing purposes. The proposed method is also directly applicable in advanced television receivers.
Source Nuclide Density First-Order and Second-Order Sensitivities in Monte Carlo Codes (2023)

Application of perturbation capabilities for density sensitivities in Monte Carlo radiation transport codes has been limited because changing source nuclide densities or source material densities changes the intrinsic source, and in most Monte Carlo codes, the user-input source is independent of the user-input materials. The perturbation capability then has no way of accounting for changes in the intrinsic source. This paper derives the sensitivity of a response with respect to a source nuclide density in terms of a portion due to the transport operator and a portion due to the source rate density. The Monte Carlo perturbation method computes the portion due to the transport operator, and the portion due to the source rate density is computed in postprocessing using parameters from the precomputed intrinsic source calculation. This paper derives first- and second-order sensitivities. The equations require the response to be separated by contribution from each of the sources modeled. A test problem containing several (α,n) and spontaneous fission neutron sources verifies the method.
Self-optimizing barrel temperature setting control of single screw extruders for improving the melt quality (2019)

Since extrusion is one of the most important manufacturing processes due to the increasing demand of polymer products, the melt quality of the polymer plays a crucial role. Indeed, the melt quality depends on the condition of preparing and processing the polymer. In fact, the resulting melt quality is highly reliant on the parameter settings of the extruder. A thermal homogeneous polymer melt as well as an increase of the throughput is conceivable. Moreover, an improper barrel temperature setting can lead to a deterioration of the material. Nowadays, the temperature of the barrel is either set with the help of an experienced process engineer or by seeking for advice from the resin manufacturer. If neither option is possible the barrel temperature can be set by applying trial and error experiments. Rather than assuming the “correct” barrel temperature setting, it is more efficient to identify the correct barrel temperature setting by means of measured quality criterions. In the 21st century, digitization permeates all areas of our lives and presents the industry with new challenges. The affected industry operators have to react promptly to the changes in the process of digitalization supposing to ensure long-term competitiveness. However, extrusion is one of the most important production processes in the polymer industry and is also facing new challenges. One of these challenges is the regulation of the barrel temperature control which influences the melt quality and thus the product quality. Certainly, the expert knowledge of the experienced machine operators represents a transitional solution which needs to be implemented by a digital and more intelligent solution. In this manner, an extruder that self-corrects the barrel temperature with the objective to meet an optimal barrel temperature setting regardless of the screw geometry and the resin is highly preferable. This is why the aim of this work concentrates on the development of a suitable control algorithm that independently detects the optimum process and controls the optimum barrel temperature setting. For this reason, rules of behavior are derived from the process behavior of the extruder in terms of its use as a basis for intelligent barrel temperature control.
Rot1p of Saccharomyces cerevisiae is a putative membrane protein required for normal levels of the cell wall 1,6- -glucan (2004)

Although ROT1 is essential for growth of Saccharomyces cerevisiae strain BY4741, the growth of a rot1Delta haploid was partially restored by the addition of 0.6 M sorbitol to the growth medium. Rot1p is predicted to contain 256 amino acids, to have a molecular mass of 29 kDa, and to possess a transmembrane domain near its C-terminus. Candida albicans and Schizosaccharomyces pombe have Rot1p homologues with high identity that also have predicted transmembrane domains. To explore the role of Rot1p, the phenotypes of the rot1Delta haploid were analysed. Deletion of ROT1 caused cell aggregation and an abnormal morphology. Analysis of the cell cycle showed that rot1Delta cells are delayed at the G2/M phase. The rot1Delta cells were resistant to K1 killer toxin and hypersensitive to SDS and hygromycin B, suggesting that they had cell wall defects. Indeed, greatly reduced levels of alkali-soluble and -insoluble 1,6-beta-glucan, and increased levels of chitin and 1,3-beta-glucan, were found in rot1Delta cells. Furthermore, the phenotypes of rot1Delta cells resemble those of disruption mutants of the KRE5 and BIG1 genes, which show greatly reduced levels of cell wall 1,6-beta-glucan. Incorporation of glycosylphosphatidylinositol (GPI)-dependent cell wall proteins in big1Delta and rot1Delta cells was examined using a GFP-Flo1 fusion protein. GFP fluorescence was detected both on the cell surface and in the culture medium, suggesting that, in these mutants, mannoproteins may become only weakly bound to the cell wall and some of these proteins are released into the medium. Electron microscopic analyses of rot1Delta and big1Delta cells showed that the electron-dense mannoprotein rim staining was more diffuse and paler than that in the wild-type, and that the outer boundary of the cell wall was irregular. A big1Deltarot1Delta double mutant had a growth rate similar to the corresponding single mutants, suggesting that Rot1p and Big1p have related functions in 1,6-beta-glucan synthesis.
Representing Data Bases in Segmented Name Spaces. (1978)

Leaf blight disease of rice (Oryza sativa) is caused by the bacterium Xanthomonas oryzae pv. oryzae. Phenol (1 to 4 mM) induced changes in protein profiles of X. o. pv. oryzae and a stress protein with a molecular mass of 69,000 appeared. HPLC analysis indicated occurrence of amino acids such as asparagine, alanine, methionine and cystine in phenol treated cells. Proton NMR analysis also revealed variation on the presence of amino acids in the cells treated with phenol.
A generalized block-edge impairment metric for video coding (1997)

A mew generalized block-edge impairment metric (GBIM) is presented in this paper as a quantitative distortion measure for blocking artifacts in digital video and image coding. This distortion measure does not require the original image sequence as a comparative reference, and is found to be consistent with subjective evaluation.
DPW-6 Results Using FUN3D With Focus on k-kL-MEAH2015 Turbulence Model (2017)

The Common Research Model wing-body configuration is investigated with the k-kL-MEAH2015 turbulence model implemented in FUN3D. This includes results presented at the Sixth Drag Prediction Workshop and additional results generated after the workshop with a nonlinear Quadratic Constitutive Relation (QCR) variant of the same turbulence model. The workshop provided grids are used, and a uniform grid refinement study is performed at the design condition. A large variation between results with and without a reconstruction limiter is exhibited on grid sizes, indicating that the medium grid size is too coarse for drawing conclusions in comparison with experiment. This variation is reduced with grid refinement. At a fixed angle of attack near design conditions, the QCR variant yielded decreased lift and drag compared with the linear eddy-viscosity model by an amount that was approximately constant with grid refinement. The k-kL-MEAH2015 turbulence model produced wing root junction flow behavior consistent with wind tunnel observations.
Space storms and radiation : causes and effects (2010)

Heliophysics is a fast-developing scientific discipline that integrates studies of the Sun's variability, the surrounding heliosphere, and the environment and climate of planets. The Sun is a magnetically variable star and for planets with intrinsic magnetic fields, planets with atmospheres, or planets like Earth with both, there are profound consequences. This 2010 volume, the second in this series of three heliophysics texts, integrates the many aspects of space storms and the energetic radiation associated with them - from causes on the Sun to effects in planetary environments. It reviews t

Experimental and theoretical investigation on the relationship between AIN properties and AIN-based FBAR characteristics (2004)

Film bulk acoustic resonators (FBARs) with an Al/AlN/Mo/Si (111) configuration are fabricated. In particular, the effects of deposition conditions on material properties of AlN films grown on Mo/Si substrate as well as the performance of FBARs are studied. Piezoelectric AlN films are deposited using RF magnetron sputtering at RF power=250 W/spl sim/600 W, N/sub 2//Ar ratio=5/25/spl sim/25/5, working pressure=5 mTorr, substrate temperature=250/spl deg/C. For all the deposited AlN films, the X-ray diffraction (XRD) spectra and full width at half maximum (FWHM) of rocking curves are measured in terms of the deposition conditions, to characterize the c-axis preferred orientation and crystal quality. The frequency response characteristics (S/sub 11/) of the fabricated FBARs are also measured. The experimental results indicate that the characteristics of FBARs can be determined by the material properties of the AlN films. Furthermore, the theoretical relation ship between the impedance parameters (R/sub m/) of the BVD model and the AlN properties has been established.

Comparison of Drug-Eluting Balloon Followed by Bare Metal Stent with Drug-Eluting Stent for Treatment of de Novo Lesions: Randomized, Controlled, Single-Center Clinical Trial (2017)

The combined use of a drug-eluting balloon (DEB) and a bare metal stent (BMS) for the treatment of de novo non-small vessel coronary artery diseases (CAD) remains to be evaluated. We investigated the efficacy of a sequential treatment using a DEB together with a BMS implantation in comparison to a zotarolimus-eluting stent (ZES). This study was a prospective, randomized, open-label study. We designed it to demonstrate the non-inferiority of a sequential treatment using a DEB first followed by a BMS (DEB + BMS) compared with the use of a ZES. The primary endpoint was in-segment late loss (LL) at 9 months measured by quantitative coronary angiography (QCA). A total of 180 patients were enrolled in the study. The 9-month follow-up angiography was performed in 72 patients with DEB + BMS and 74 patients with ZES. When comparing the DEB + BMS results with the ZES ones, LL was 0.50 ± 0.46 mm in DEB + BMS patients vs. 0.21 ± 0.44 mm in ZES patients (P < 0.001). The mean difference of the LL was 0.31 mm, which was larger than the prespecified non-inferiority margin of 0.19 mm, and the 2-sided 95% confidence interval was 0.15-0.48. The clinical outcomes were not significantly different. In conclusion, the DEB + BMS strategy is inferior to the ZES one in terms of the LL result at 9 months. The DEB strategy for de novo coronary artery lesions needs to be improved for it to become an alternative treatment option.
Fine Powder Flow Phenomena in Bins, Hoppers, and Processing Vessels 1 (2000)

Fine powders often exhibit significant twophase (solid/gas) interactions when they are handled in bins, hoppers, and processing vessels. As a result, numerous and more complex flow problems can occur which are not observed with larger particle bulk solids. The powder’s flow pattern has a major effect on the development of certain flow problems, especially flooding. This can usually be overcome by using mass flow designs. Unfortunately, when mass flow is achieved the powder’s discharge rate through a hopper outlet may be severely restricted.
Hypofractionated Stereotactic Radiosurgery for Brain Metastases (2021)

Hypofractionated stereotactic radiotherapy (HSRT) with modern image-guidance is a method for the treatment of brain metastases, which differs technically and radiobiologically from traditional single-fraction stereotactic radiosurgery (SRS). HSRT is based on a non-invasive mask-based treatment platform, and fractionates stereotactic intracranial treatment into 5 or fewer fractions. The intent of HSRT is to maximize the therapeutic ratio by enabling safe and effective treatment of large brain metastases, for re-irradiation of brain metastases, and for those metastases in close proximity to (or within) critical organs-at-risk that would normally preclude effective single-fraction SRS. In this review, we first summarize the current state of knowledge with respect to the epidemiology and treatment of brain metastases. Next, we discuss the rationale for HSRT and present the evidence supporting HSRT for the treatment of large intact brain metastases. Then, we discuss the evidence for treating post-operative brain metastases cavities with HSRT. Lastly, we present the evidence for multi-staged HSRT for brain metastases as a novel alternative to standard daily HSRT.
Peritoneal resorption capacity for the inflammatory mediators in acute experimental Staphylococcus aureus peritonitis. (2009)

There was a clear reduction in peritoneal resorption of endotoxin and IL-6 in this acute model of gram-positive peritonitis.
Poloidal divertor experiment with applied E vector x B vector/B/sup 2/ drift (1980)

It has been proposed that the E vector x B vector/B/sup 2/ drift arising from an externally applied electric field could be used in a tokamak or other toroidal device to remove plasma and impurities from the region near the wall and to reduce the amount of plasma striking the wall, either assisting or replacing a conventional magnetic field divertor. A poloidal magnetic divertor (without pumping chamber) was added to the Wisconsin Levitated Toroidal Octupole, and the octupole was operated with a tokamak-like magnetic field configuration (q = 0.7). A radial electric field was applied in the scrape-off zone, causing an E vector x B vector/B/sup 2/ drift with a large poloidal component. This reduced plasma flux reaching the wall of the toroid by up to a factor of 5 beyond the effect of the magnetic divertor, for divertor configurations with both high and low magnetic mirror ratios, in good agreement with a simple theoretical model. Plasma density and density scale length were also reduced in the scrape-off zone, in qualitative agreement with the model. This was not accompanied by any new instabilities in the scrape-off zone, nor by any appreciable degradation of confinement of the central plasma.
Medical and psychological team work in the care of chronically ill children. (1955)

THE CARE of chronically in children differs from that of adults in at least 3 ways. First, except for mental retardation and leukemia, and now even for leukemia, it is expected that the chronically ill child will recover. Hence the attitude of pediatricians and other general practitioners is more hopeful than that of internists, surgeons, psychiatrists and psychologists. Second children do not understand the reason for being ill, and sometimes are bewildered and rebellious. Third, in addition to all of the problems of chronically ill adults, children need tender loving care, education and provision for growth and development. The goal of the pediatrician and family physician is to help children recover rapidly, happily and hopefully without invalidism and maladjustment, and team work obviously is essential.

Ginger for chemotherapy-related nausea in cancer patients: A URCC CCOP randomized, double-blind, placebo-controlled clinical trial of 644 cancer patients (2009)

9511 Background: Despite the widespread use of antiemetics, post-chemotherapy nausea and vomiting continue to be reported by up to 70% of patients receiving chemotherapy. Ginger (Zingiber Officinale), an ancient spice, is used by practitioners worldwide to treat nausea and vomiting. We conducted a multi-site, phase II/III randomized, placebo-controlled, double-blind clinical trial to assess the efficacy of ginger for chemotherapy-related nausea in cancer patients at the University of Rochester-affiliated Community Clinical Oncology Program (CCOP) member sites. Methods: Cancer patients who experienced nausea following any chemotherapy cycle and were scheduled to receive at least three additional cycles were eligible. Patients were randomized into four arms: 1) placebo, 2) 0.5g ginger, 3) 1.0g ginger, or 4) 1.5g ginger. All patients received 5-HT 3 receptor antagonist antiemetics on Day 1 of all cycles and took three 250mg capsules of ginger or placebo twice daily for six days starting three days before the first day of the next two cycles. Patients reported the severity of nausea during the morning, afternoon, evening, and night on a 7-point semantic rating scale (‘1' = ‘Not at all Nauseated' and ‘7' = “Extremely Nauseated”) for Days 1–4 of each cycle. The goal was to determine if ginger was more effective than placebo in controlling chemotherapy-related nausea in participants given a 5-HT 3 receptor antagonist antiemetic. Results: A total of 644 patients were accrued (90% female, mean age = 53). Breast (66%), alimentary (6.5%), and lung (6.1%) cancers were the most common cancer types. Analysis of covariance (ANCOVA) examined change in nausea in the four study arms on Day 1 of cycles 2 and 3. All doses of ginger significantly reduced nausea (p=0.003). The largest reduction in nausea occurred with 0.5g and 1.0g of ginger. Also, time of day had a significant effect on nausea (p&lt;0.001) with a linear decrease over 24 hours for patients using ginger. Conclusions: Ginger supplementation at daily dose of 0.5g-1.0g significantly aids in reduction of nausea during the first day of chemotherapy. Supported by NCI PHS grants 1R25CA10618 and U10CA37420.

A New Synthesis of γ-Butyrolactones via AuCl3- or Hg(II)-Catalyzed Intramolecular Hydroalkoxylation of 4-Bromo-3-yn-1-ols (2012)

An efficient conversion of 4-bromo-3-yn-1-ols to γ-butyrolactones via AuCl(3)-catalyzed electrophilic cyclization (hydroxyl-assisted regioselective hydration) in wet toluene is described. Various secondary and tertiary alcohols including benzylic systems were found to be equally reactive with moderate to excellent yields obtained in all cases.
Peripheral blood stem cell collection and autografting in high risk lymphomas. (1992)

Peripheral blood stem cells (PBSC) were collected from 29 patients with high risk Hodgkin's disease (n = 3) or non-Hodgkin's lymphoma (n = 26) in partial remission or first sensitive relapse. Patients had either bone marrow involvement or hypoplastic bone marrow. The conditioning regimen prior PBSC collection included amsacrine and cytosine arabinoside (Ara-C) or Ara-C alone. PBSC collection was performed after leukocyte counts reached 1 x 10(9)/1. A good yield was obtained in 23 patients, whereas sufficient numbers of CFU-GM were not obtained in six cases. Twenty-one patients have been transplanted. All patients except one achieved bone marrow engraftment. Eight patients are in complete remission (mean duration 15 months). The estimated 2 years survival rate is 46.4% (CI 25-68%). This procedure would seems a good alternative in poor prognosis lymphomas.
A comparative scanning electron microscopic study on degradation of absorbable ligating clips in vivo and in vitro (1988)

Using scanning electron microscopy, the degradation characteristics of two absorbable ligating clips, Absolok (polydioxanone) and Lactomer (poly-L-lactide-co-30%-glycolide) have been studied under in vivo and in vitro conditions. The rate of Absolok clip degradation was significantly greater than that of Lactomer clip degradation both in vitro and in vivo. The rate of degradation of Lactomer clips significantly increased and they showed a greater change in proportion of breakdown in vivo than in vitro compared to Absolok clips. The Absolok clip breakdown began with the formation of surface undulations which later developed into fissures. The undulations appeared on the clip surface as early as 7 days and by 2 weeks developed into fissures. The initial appearance of the fissures was at the edge of the clips particularly at the mating surface. The thickness of layers forming the fissures gradually decreased and by 15 weeks the layers appeared as very thin sheets of materials. The high energy areas (locking and molding points) were more resistant to breakdown and the remains of the clips were still present 25 weeks after initiation of the experiments. The Lactomer clips showed very little sign of degradation in vitro even after 10 weeks of incubation. However, in the in vivo experiments undulations formed on the clip surface as early as 2 weeks postimplantation. These clips also showed fissures similar to those observed on Absolok clips.
