Hybrid fractal cross antenna (2000)

A new fractal geometry of the cross antenna, which belongs to the traveling-wave antenna class and follows the contour of a cross, is presented. In the conventional type of traveling-wave antenna, the total length of the radiating conductor increases as the order of fractal expansion increases, but this increase of the length of the current path degrades the performance of the antenna. To reduce the antenna performance degradation, a hybrid fractal antenna is presented, which divides the entire fractal structure into some smaller ones, and connects each smaller fractal group with a power divider circuit. The secondarily, thirdly, and fourthly expanded hybrid fractal cross antennas are fabricated, and their performances are examined by measurements. The influences of the fractal order on the antenna performance are examined. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 429–435, 2000.
Physicochemical characterization of Theobroma cacao L. mucilage, in Ecuadorian coast (2016)

In 2014, Ecuador generated 141,000 MT of cocoa sweatings equivalent to 12,320 MT of reducing sugars that through fermentation can become Bioetanol. Cocoa sweatings was characterized to determinate its potential as biofuel. Methodologies described by AOAC 2005 standards were used. Values of 10.6 Brix; pH 3.58; density 1.10 g/ml, total sugars 12,33% reducing sugars 6.39% were observed. Chemical groups such as alkaloids, reducing sugars, and coumarins triterpenoid were identified by phytochemical screeninng. 20 chemical compounds were detected using by gas chromatography mass spectrometry (GC-MS): 3 carboxilic acids, 4 sugar acids, 3 sugar alcohols, 2 amino acids, 1 furan, 2 lactones, 1 monosaccharides, 2 disaccharides and 2 glycosides. They represent the 11.08% of total compounds separated, and Sucrose (2.15%), glucose (2.13%) and fructose (4.42%) were identified by high performance liquid chromatography (HPLC). The study showed that for each kilogram of dry cocoa produced 0.59 kg of mucilage are obtained and its sugars are an interesting source of raw material for the production of second generation bioethanol, results that contribute to reducing the environmental impact that generate these waste.
[Deterioration in ventricular arrhythmia caused by anti-arrhythmia preparations]. (1984)

Study of the efficacy of some antiarrhythmic drugs in 92 patients with frequently occurring ventricular premature heart beat including high grades has demonstrated that in an insignificant number of patients these drugs produce an arrhythmogenic action. Such an action is observed after intake of the common therapeutic drug dose and is not accompanied by subjective symptoms pointing to the drug intolerance. The arrhythmogenic action of the drugs results in a dramatic increase in the number of ventricular premature heart beats and in the appearance of high grades of such beats including the development of ventricular flutter.
Compromises with Serialism (1961)

Until a few years ago, my title could have stood without any need for further clarification: serialism , however mistrustfully it might be received in precept or example, was clearly understood to be that method of pitch relationship devised by Schoenberg. The emergence with the post-war generation of methods that treat many other musical properties as equally susceptible to a serial ordering has favoured the relegation of the earlier techniques to a class known variously as twelve-note music , or more elaborately dodecatonicism , or with dubious etymological justification dodecaphony.
Ring opening and ring contraction in reactions of some aminobromo‐ and dibromoisoquinolines with potassium amide in liquid ammonia (1974)

Abstract Reactions of some aminobromo‐ and dibromoisoquinolines with KNH 2 in liquid NH 3 have been investigated. Compounds with an amino group and a bromo atom in positions α to the heteroatom, show a very fast ring opening, leading to o ‐cyanobenzyl cyanide. The 1,4‐substituted aminobromoisoquinolines do not react; 4‐amino‐3‐bromoisoquinoline undergoes ring opening into o ‐cyanobenzyl isocyanide, 3‐amino‐4‐bromoisoquinoline ring contraction to 1‐cyanoisoindole. The dibromoisoquinolines react primarily by nucleophilic substitution.

Biventricular pacing: current trends and future strategies (2011)

The role of biventricular pacing is expanding beyond the New York Heart Association classes III and IV heart failure (HF) patient to include less symptomatic patients, earlier in the course of their disease process. This multisite pacing strategy has substantially altered the natural course of ventricular failure, exerting its physiological impact through favourable cardiac remodelling and improving the ejection fraction. This has in turn resulted in long-term clinical benefits such as improved quality of life and functional capacity with a concomitant reduction in hospitalization for HF and overall mortality. Despite the successes of cardiac resynchronization therapy (CRT) and the recent expansion of its role in the treatment of HF patients, there remain some inherent limitations to the technology and its delivery. A significant minority of patients continue to remain non-responsive to this pacing strategy. This review will highlight biventricular pacing in its present form, will elaborate on strategies to enhance response to CRT, and outline future trends and synergies towards maximizing the potential benefit of this therapeutic modality.
Is Refraction in Early Infancy a Predictor of Myopia at the Age of 7 to 8 Years? The Relationship between Cycloplegic Refraction at 11 Weeks and the Manifest Refraction at Age 7 to 8 Years in Chinese Children (1999)

Thirty-two children who had been refracted in early infancy were re-refracted at the age of 7 to 8 years. Refraction comprised cycloplegic retinoscopy at the mean age of 11 weeks and noncycloplegic retinoscopy and subjective examination at the mean age of 94 months. The change in spherical equivalent refraction (SER) was highly negatively correlated with the initial refraction (-0.863), demonstrating emmetropization; however, the correlation between the refractive error at age 7 to 8 years and the refractive error in infancy was much weaker (+0.225). The SER was significantly less and the astigmatism was greater in infancy in children who were myopic at age 7 to 8 years. There was, however, extensive overlap in range between the SER for the two groups and the initial SER was not a good predictor of myopia at 7 to 8 years, although it may help to identify children who are unlikely to become myopic. One hyperopic child with bilateral ptosis failed to emmetropize.
Automation for Contract Laboratories — Benefits from a Customer Perspective (2001)

Automation requires significant capital investment and for contract laboratories this funding may be difficult to justify. However, with increasing commitment to the automation of dosage form analysis by pharmaceutical companies and the adoption of automation earlier in the development process, outsourcing of automated methods will be an important requirement in the future. Contract laboratories that do not have automation equipment will not be able to compete as effectively for business as those that have this capability. The benefits to the customer of outsourcing automated methods will be discussed together with the potential problems for the contract laboratory in forming a strategy to meet this need. The adoption of new technology in other development functions (e.g., bioanalysis), by pharmaceutical companies and contract facilities has been very successful. The learnings from this situation will also be briefly outlined to provide some perspective around the implementation of automated methods.
Environmental Controls on the Surface Energy Fluxes over a Southern Open Water Surface in USA: An Annual Analysis (2010)

We measured the surface energy fluxes using an eddy covariance system on a tower that was located in the middle of a large southern open water surface of the Ross Barnett Reservoir (the Reservoir hereafter) in Mississippi, USA, for a 1-year period in 2008. The Reservoir was ice-free over a course of year. We analyze diurnal, monthly, and seasonal variations in radiative balance and turbulent fluxes and sensible and latent heat. Our objective is to quantify environmental controls on turbulent exchanges of surface energy fluxes and their variation patterns over a course of year in 2008.
Primitive CML cell expansion relies on abnormal levels of BMPs provided by the niche and on BMPRIb overexpression (2013)

Leukemic stem cells in chronic phase chronic myelogenous leukemia (CP-CML) are responsible for disease persistence and eventual drug resistance, most likely because they survive, expand, and are sustained through interactions with their microenvironment. Bone morphogenetic proteins 2 (BMP2) and 4 (BMP4) regulate the fate and proliferation of normal hematopoietic stem cells, as well as interactions with their niche. We show here that the intrinsic expression of members of the BMP response pathway are deregulated in CML cells with differences exhibited in mature (CD34(-)) and immature (CD34(+)) compartments. These changes are accompanied by altered functional responses of primitive leukemic cells to BMP2 and BMP4 and strong increases in soluble BMP2 and BMP4 in the CML bone marrow. Using primary cells and a cell line mimicking CP-CML, we found that myeloid progenitor expansion is driven by the exposure of immature cells overexpressing BMP receptor Ib to BMP2 and BMP4. In summary, we demonstrate that deregulation of intracellular BMP signaling in primary CP-CML samples corrupts and amplifies their response to exogenous BMP2 and BMP4, which are abnormally abundant within the tumor microenvironment. These results provide new insights with regard to leukemic stem cell biology and suggest possibilities for the development of novel therapeutic tools specifically targeting the CML niche.
The Use of Cyanoacrylate Adhesive With a Collagen Shield in Leaking Filtering Blebs (1989)

We describe our technique for sealing leaking filtering blebs with cyanoacrylate adhesive, using a collagen shield to cover the adhesive. We believe the shield makes the patient more comfortable and decreases the likelihood of dislodgement of the adhesive.
Complementary and alternative therapies for post-traumatic stress disorder (2020)

Salvia Reuterana can be used as an alternative for treatment of several disorders.
High-Resolution Computed Tomography Image Reconstruction in Sinogram Space (2013)

An important part of any computed tomography (CT) system is the reconstruction method, which transforms the measured data into images. Reconstruction methods for CT can be either analytical or iterative. The analytical methods can be exact, by exact projector inversion, or non- exact based on Back projection (BP). The BP methods are attractive because of their simplicity and low computational cost. But they produce sub-optimal images with respect to artifacts, resolution, and noise. This paper deals with improve of the image quality of BP by using super- resolution technique. Super-resolution can be beneficial in improving the image quality of many medical imaging systems without the need for significant hardware alternation. In this paper, we propose to reconstruct a high- resolution image from the measured signals in Sinogram space instead of reconstructing low-resolution images and then post-process these images to get higher resolution image. 
Design methodology and advances in nested-Miller compensation (2002)

The nested Miller compensation of three-stage amplifiers is reviewed by using a simple design-oriented approach. The method provides stable amplifiers by accurately controlling the overall phase margin as well as that of the internal loop. Furthermore, the use of nulling resistors to remove the RHP zeros is discussed and optimization criteria are described. A novel technique is presented which allows an amplifier's frequency and settling performance to be greatly improved without increasing power consumption. Thanks to the small compensation capacitors employed, the approach is amenable for integration and in particular where large load capacitors have to be driven. SPICE simulations based on a 0.8-/spl mu/m CMOS design are given and found in remarkable agreement with the theoretical analysis.
Are antihistamines useful in managing asthma? (2002)

There continues to be a great deal of interest in the anti-asthmatic role of antihistamines. Antihistamines have recently been shown to have anti-inflammatory properties that are more extensive than simply the blocking of histamine receptors. For example, new evidence suggests that the suppression of cell adhesion molecule expression occurs with these drugs. The anti-inflammatory and anti-asthmatic effects of antihistamines have been evaluated in patients with both allergic asthma and rhinitis, given the established association between allergic inflammation of the upper and lower airways, with evidence to suggest that antihistamines have clinically relevant anti-asthmatic properties. As well as conferring benefits in asthma symptom control and the measurement of lung function, studies assessing the effect of histamine receptor antagonists on bronchial hyperresponsiveness suggest that there is bronchoprotection during both methacholine and mannitol challenges. Recently, there has also been considerable interest in the effect of combining an antihistamine with a leukotriene receptor antagonist. This combination has an anti-asthmatic effect that is greater than that of either drug given alone and may be comparable to inhaled corticosteroid therapy.

AAPM/RSNA Physics Tutorial for Residents (2004)

Recent advances in digital detector technology have paved the way to full-field digital mammography (FFDM) systems. The performance of these systems has evolved to the point where replacement of screen-film mammography (SFM) systems is becoming realistic. Despite some commonality between the two techniques, there are fundamental differences in how images are recorded, displayed, and stored. These differences necessitate an understanding of the principles of detection and the characteristics of digital images. Several approaches have been taken in the development of FFDM systems: (a) slot scanning with a scintillator and a charge-coupled device (CCD) array, (b) a flat-panel scintillator and an amorphous silicon diode array, (c) a flat-panel amorphous selenium array, (d) a tiled scintillator with fiberoptic tapers and a CCD array, and (e) photostimulable phosphor plates (computed radiography). Although the initial cost of an FFDM system is high compared with that of an SFM system, digital mammography has inherent advantages, such as wide dynamic range, reduction in recall rates, potential for reduction in radiation dose, increased patient throughput, postprocessing capability, and digital acquisition. These advantages and the rapidly occurring technologic developments will help establish FFDM as a mainstay of breast evaluation.
An EM Approach to OD Matrix Estimation (1994)

Consider a &quot;black box&quot; having I input channels and J output channels. Each arrival on an input channel gets routed through the black box and appears on an output channel. The system is monitored for a fixed time period and a record is made of the number of arrivals on each input channel and the number of departures on each output channel. The OD (origination-destination) matrix estimation problem is to estimate, for each i and j, the number of arrivals on channel i that depart on channel j. We introduce a Poisson stochastic model and employ the EM algorithm to produce high likelihood estimates. In the case of estimation based on observations over a single time-period, we analyze in detail the fixed points of the EM algorithm showing that every vertex of a certain polytope of feasible matrices is a fixed point and identifying a specific interior fixed point which is a saddle point for the likelihood function.

Two muscle-specific LIM proteins in Drosophila. (1996)

The LIM domain defines a zinc-binding motif found in a growing number of eukaryotic proteins that regulate cell growth and differentiation during development. Members of the cysteine-rich protein (CRP) family of LIM proteins have been implicated in muscle differentiation in vertebrates. Here we report the identification and characterization of cDNA clones encoding two members of the CRP family in Drosophila, referred to as muscle LIM proteins (Mlp). Mlp60A encodes a protein with a single LIM domain linked to a glycine-rich region. Mlp84B encodes a protein with five tandem LIM-glycine modules. In the embryo, Mlp gene expression is spatially restricted to somatic, visceral, and pharyngeal muscles. Within the somatic musculature, Mlp84B transcripts are enriched at the terminal ends of muscle fibers, whereas Mlp60A transcripts are found throughout the muscle fibers. The distributions of the Mlp60A and Mlp84B proteins mirror their respective mRNA localizations, with Mlp84B enrichment occurring at sites of muscle attachment. Northern blot analysis revealed that Mlp gene expression is developmentally regulated, showing a biphasic pattern over the course of the Drosophila life cycle. Peaks of expression occur late in embryogenesis and during metamorphosis, when the musculature is differentiating. Drosophila Mlp60A and Mlp84B, like vertebrate members of the CRP family, have the ability to associate with the actin cytoskeleton when expressed in rat fibroblast cells. The temporal expression and spatial distribution of muscle LIM proteins in Drosophila are consistent with a role for Mlps in myogenesis, late in the differentiation pathway.
Soñar pinturas, pintar sueños. Diálogo inter-artístico en Willy el soñador de A. Browne (2014)

Poetas y artistas, han advertido en varios momentos de la historia del arte, la importancia de reparar en la significación de las analogías o “correspondencias”. El concepto ha sido abordado desde distintos puntos de vista y en un constante diálogo inter-artístico. Los románticos, Baudelaire, Proust y Benjamin, son ejemplos que evidencian esta preocupación por las relaciones artísticas. En esta oportunidad se intentará manifestar el diálogo inter-artístico que se produce en Willy el soñador de Anthony Browne, indagando las relaciones entre la literatura infantil y la historia del arte visual, específicamente el caso de Magritte y la influencia del surrealismo.
PMP22 expression in dermal nerve myelin from patients with CMT1A (2009)

Charcot-Marie-Tooth disease type 1A (CMT1A) is caused by a 1.4 Mb duplication on chromosome 17p11.2, which contains the peripheral myelin protein-22 (PMP22) gene. Increased levels of PMP22 in compact myelin of peripheral nerves have been demonstrated and presumed to cause the phenotype of CMT1A. The objective of the present study was to determine whether an extra copy of the PMP22 gene in CMT1A disrupts the normally coordinated expression of PMP22 protein in peripheral nerve myelin and to evaluate PMP22 over-expression in patients with CMT1A and determine whether levels of PMP22 are molecular markers of disease severity. PMP22 expression was measured by taking skin biopsies from patients with CMT1A (n = 20) and both healthy controls (n = 7) and patients with Hereditary Neuropathy with liability to Pressure Palsies (HNPP) (n = 6), in which patients have only a single copy of PMP22. Immunological electron microscopy was performed on the skin biopsies to quantify PMP22 expression in compact myelin. Similar biopsies were analysed by real time PCR to measure PMP22 mRNA levels. Results were also correlated with impairment in CMT1A, as measured by the validated CMT Neuropathy Score. Most, but not all patients with CMT1A, had elevated PMP22 levels in myelin compared with the controls. The levels of PMP22 in CMT1A were highly variable, but not in HNPP or the controls. However, there was no correlation between neurological disabilities and the level of over-expression of PMP22 protein or mRNA in patients with CMT1A. The extra copy of PMP22 in CMT1A results in disruption of the tightly regulated expression of PMP22. Thus, variability of PMP22 levels, rather than absolute level of PMP22, may play an important role in the pathogenesis of CMT1A.
Face recognition using eigenface approach (2012)

In this article, a face recognition system using the Principal Component Analysis (PCA) algorithm was implemented. The algorithm is based on an eigenfaces approach which represents a PCA method in which a small set of significant features are used to describe the variation between face images. Experimental results for different numbers of eigenfaces are shown to verify the viability of the proposed method.
A genetic algorithm for the optimization of prostate implants (1996)

A genetic algorithm (GA) is presented for the optimization of template- and ultrasound-guided prostate implants. The end points for optimization are incorporated in an objective function of separable cardinal utility terms. As an application of the GA, the minimum 103Pd total source strength required to deliver a given dose was correlated with the average dimension for prostate implants carried out under the current template and seed spacing protocols. Significant improvements in quality were observed, in terms of both the minimum peripheral dose and tumor cell surviving fractions, when GA-optimized implants were compared to the corresponding unoptimized implants for given target volumes. In addition, numerical simulation of source displacements indicates that the dosimetric and radiobiologic advantages of GA optimization can tolerate a reasonable level of seed placement uncertainties observed clinically. In summary, the GA application provides an automated design strategy for prostate implant planning, and at the same time affords the potential for systematic optimization of a set of end points that can sustain practical variations.
