Diagnóstico de enfermedad arterial coronaria en pacientes con bloqueo de la rama izquierda del haz de His: SPECT cardiaco versus angiotomografía coronaria

El bloqueo de rama izquierda del haz de His se asocia a enfermedad arterial coronaria y muerte cardiovascular. Objetivo: Este estudio compara la certeza diagnostica de la tomografia computarizada con emision de foton unico y la angiotomografia coronaria en la deteccion de enfermedad coronaria en pacientes con bloqueo de rama izquierda. Me- todos: Se incluyeron 23 pacientes a quienes se les realizo tomografia computarizada con emision de foton unico cardiaco y angiotomografia coronaria. La certeza diagnostica de ambos metodos para detectar enfermedad arterial coronaria (> 50% de estenosis) fue comparada con angiografia coronaria invasiva. Resultados: La tomografia computarizada con emision de foton unico cardiaco identifico correctamente 8 de 14 pacientes sin enfermedad coronaria significativa y 8 de 9 pacientes con estenosis > 50%. La angiotomografia coronaria identifico correctamente 12 de 14 pacientes sin enfermedad coronaria significativa y los 9 pacientes de 9 con estenosis > 50%. La certeza diagnostica global, sensibilidad, especificidad, valor predictivo positivo y negativo para la tomografia computarizada con emision de foton unico cardiaco fueron 69, 88, 57, 57 y 88% respectivamente y para la angiotomografia coronaria fueron 91, 100, 85, 81 y 100%. Conclusiones: La certeza diagnostica de la angiotomografia coronaria para detectar enfermedad arterial coronaria en pacientes con bloqueo de rama izquierda es mayor, por lo que podria proponerse como el primer metodo de imagen no invasiva en la evaluacion de pacientes con estas caracteristicas
A control strategy for parallel voltage source inverters

This paper presents a simple, effective and robust control strategy applied to parallel connected single phase voltage source inverters. The proposed control has two instantaneous average values control loops: one for voltage and another for current. The first one controls the output voltage of the inverter while the second is designed to control the parallel operation of the inverters. The proposed parallelism control acts in the voltage before the LC filter and is based in the feedback of the L inductor current. There is no communication among inverters so that one unit is independent from the others. A prototype with 3 inverters of 5 kVA each was built to corroborate the control technique.
Polynomial estimates towards a sharp Helly-type theorem for convex sets

We discuss a problem posed by Bárány, Katchalski and Pach: if {Pi : i ∈ I} is a family of closed convex sets in R such that diam (⋂ i∈I Pi ) = 1 then there exist s 6 2n and i1, . , is ∈ I such that diam (Pi1 ∩ · · · ∩ Pis) 6 Cn, where Cn 6 c √ n for an absolute constant c > 0. We prove that this statement holds true with Cn 6 cn. All the previously known estimates for Cn were exponential or superexponential in the dimension n.
Length of stay and recidivism in schizophrenia: a study of public psychiatric hospital patients.

OBJECTIVE Psychiatric beds in public hospitals have decreased 80% since 1955, but admissions have risen correspondingly, largely because of high recidivism rates. Decreases in numbers of beds have been partly achieved by shortening the length of stay, which lessened by half between 1970 and 1980. This study was undertaken to determine whether duration of hospital treatment affects the rate and rapidity of relapse among schizophrenic patients. METHOD Data on 1,500 patients from 10 state hospitals were gathered for 18 months after initial discharge. Predictor variables included age, sex, marital status, race, number of previous admissions, location of the facility, and length of stay. Data were analyzed by survival analysis with a Cox regression model for two times to initial relapse: 30 days and 18 months (outcome). RESULTS Length of stay was significantly related to each time to relapse after the effects of number of previous admissions and age were partialed out. Facility location was not predictive, but intrahospital effects were tested by examining the data on the largest facility; again, length of stay significantly predicted relapse. CONCLUSIONS Although the magnitude of the effect was small, the clinical significance of the findings is the greater likelihood that brief-stay patients will be rehospitalized within 30 days after discharge than will patients treated for longer periods. Brief hospitalization seems generally applicable to psychiatric populations, but there may be a small but important group of seriously mentally ill patients for whom other alternatives are possibly more appropriate and should be explored.
Muscle fiber necrosis in murine dystrophy

A sampling technique based on spaced serial ultrathin sections was used to examine the ultrastructure and cytoarchitecture of myofibers, which were necrotic throughout their length, in the dytrophic mutant mouse (C57BI6J/dy2J). Regional variations along the length of the myofibers were described. The necrotic fibers extended the full length of the muscle fascicle and did not branch. In necrotic fibers which were free of invasive cells, the only nuclei found under the basal lamina were peripherally placed, euchromatic myonuclei, or nuclear membrane remnants. In these fibers, the nuclear population was ∼ 14% of the nuclear population of “healthy” fibers from the same animals. No myosatellite cells were observed to be associated with these necrotic fibers. In necrotic fibers, which had undergone foreign cell invasion, the existence of a pleomorphic population of mononucleated invasive cells, many of which had not begun to express phagocytic characteristics, caused considerable confusion, because their appearance tended to mimic that of myonuclei or satellite cells. No heterochromatic nuclei or true myosatellite cells were found associated with necrotic fibers displaying macrophage invasion.
Plant Leaf Diseases Identification using Convolutional Neural Network with Treatment Handling System

Agriculture is a very crucial industry to Malaysia where it would bring a huge impact on the country’s wealth. All plant species, regardless of cultivated or wild, are prone to diseases and it is often inevitable. In the older days, identification of plant diseases was done by the experts of the field through observing the plants manually which can be rather tedious, time consuming and often inaccurate. With the advent of image processing technologies, automatic detection of plant disease can be done by capturing and processing the image of the plant leaves. In this paper, the K-means clustering and color thresholding are applied for image segmentation of the plant leaf. Both algorithms are compared in the study to evaluate which serves as a better segmentation algorithm on a target dataset to segment the region of interest (ROI). Moreover, two feature extraction approaches of ResNet-50 Convolutional Neural Network (CNN) and Gray-Level Co-Occurrence Matrix (GLCM) are also studied to evaluate their performance as a feature extractor. With applying the CNN to the support vector machine (SVM) classifier, it is investigated that an average classification accuracy of 96.63% can be achieved to perform the classification of the leaf diseases. A graphical interface for the system is also developed to provide the treatment handling method for the detected diseases.
46 Scandium metabolism; binding to metalloproteins in vivo and in vitro.

Following the injection of rabbits with ${}^{46}{\rm Sc}$ as 1:2 citrate complex, the binding of scandium to metalloproteins and erythrocytes was studied. Binding to erythrocytes reached a peak after three days and thereafter declined with the plasma radioactivity level. This peak was not due to binding to haem as no incorporation into isolated haemin was observed. Scandium was shown to be transferred between transferrin and ferritin in vitro although in vivo the binding to ferritin appeared to be negligible compared with some other transition metals. The excretion of ${}^{46}{\rm Sc}$ in bile was studied using polyacrylamide gel electrophoresis. No specific scandium-protein complexes were observed, radioactivity being associated either with the bile pigments, or precipitated at the start of the gels or else associated with the small amount of transferrin naturally excreted in the bile.
Weblogs and the Epistemology of the News: Some Trends in Online Journalism

Journalism has been slow to develop distinctive forms in response to the new contexts provided by the internet. One rapidly developing form, unique to the world wide web, is the weblog. This article reviews the claims made by proponents of the form and explores, through the case study of a weblog produced by the British Guardian newspaper, epistemological differences to the dominant Anglo-American news form. The article argues that the rearticulation in this institutional product of the relation between journalists and users, of the claim to authority made in the news text and of the news text as product, provides historians of both journalism and new media with a case study of the adaptation of journalism to new contexts.
Body image in adult women: Associations with health behaviors, quality of life, and functional impairment

This study examined body image in adult women along with probable correlates including health behaviors, negative affect, quality of life, and functional impairment. Adult women (N = 738, age = 25–86 years) completed an online survey assessing these domains. Women across all ages reported similar body image concerns. Negative body image significantly correlated with poorer wellness behaviors, negative affect, quality of life, and functional impairment. The inverse held for positive body image. The majority of correlations remained even when controlling for negative affect. Further research is warranted to investigate nature of the correlational relationships identified in this study.
Epidural infusion or combined femoral and sciatic nerve blocks as perioperative analgesia for knee arthroplasty.

BACKGROUND Peripheral neural blockade appears to provide effective analgesia with potentially less morbidity than central neuraxial techniques. We compared the relative benefits of combined femoral (3-in-1) and sciatic nerve block with epidural blockade for postoperative knee arthroplasty analgesia. METHODS Sixty patients, ASA I-III, undergoing unilateral knee replacement were prospectively randomized to receive either a lumbar epidural infusion or combined single-shot femoral (3-in-1) and sciatic blocks (combined blocks). All patients received standard general anaesthesia. Visual analogue pain scores and rescue opioid requirements were recorded at four time points postoperatively. Patient satisfaction, morbidity, block insertion time, perioperative blood loss and rehabilitation indices were also assessed. RESULTS In both groups, pain on movement was well controlled at discharge from recovery and 6 h postoperatively but increased at 24 and 48 h. Median (95% CI) analogue scale scores were 0 (0-0), 15 (0-30), 55 (38-75) and 54 (30-67) mm for epidural block and 0.5 (0-22), 21.5 (10-28), 40 (20-50) and 34.5 (21-55) mm for combined block. VAS pain scores with the combined blocks were significantly lower at 24 h (P=0.004). Total morphine usage was low in both groups: median epidural group 17 mg (8-32) versus combined blocks 13 mg (7.8-27.5). Patient satisfaction was high in both groups with median (95% CI) scores of 100 (85-100), 83 (70-100) and 82 (57-90) mm for epidural and 90 (73-100), 100 (77-100) and 97 (80-100) mm for combined blocks (not significant). Perioperative blood loss and rehabilitation indices were also similar. CONCLUSIONS Combined femoral (3-in-1) and sciatic blocks offer a practical alternative to epidural analgesia for unilateral knee replacements.
The Interpretation of Scriptures

A vast amount of labor has been devoted to the interpretation of the Bibles of mankind. Much of the later matter which makes up the Scriptures themselves is intended to be interpretative of the earlier. After this usually comes a body of tradition, and following the tradition an endless array of commentaries reaching down through the centuries, not to mention the thousands of volumes of theological and religious works in which the aim of interpreting the Scriptures is more or less dominant, though not so explicit as in the commentaries. It is true that the Bibles do not stand entirely alone in this respect. Commentaries on Homer and Shakespeare have been numerous; indeed, practically all outstanding literature of the past has been the object of this sort of effort. Yet in the enormous extent of the interpretative matter which they have inspired, the Scriptures are unrivaled. Their great age is one reason for this, but not the main reason. It has been due mainly to their exalted position: to the belief that they and they alone could show to man the way of life. Had it not been for the influence of this belief it is safe to say that the literature which has grown up around the great Scriptures would not have reached a fraction of the extent which it has reached.
Expression of epithelial growth factor receptor in oral epithelial dysplastic lesions

Aim: The aim of the study was to assess the expression of epithelial growth factor receptor (EGFR) in normal oral mucosa and varying grades of oral epithelial dysplasia (OED) and to correlate these findings, with clinicopathologic features and findings on routine hematoxylin and eosin–stained (H and E) sections. Materials and Methods: Twenty-nine formalin-fixed, paraffin-embedded blocks of various grades of OED and 10 normal mucosa were stained with routine H and E and immunostained with EGFR by avidin–biotin method. Results: The results showed a significant increase in the staining reactions in varying grades of dysplasia as compared with normal mucosa. Conclusion: EGFR can be considered as an early marker of a cell proliferation and maturation as well as early marker of epithelial dysplasia and onset of cancer in oral dysplasia. However, further studies with a larger sample size and continuous followup is suggested to determine its role and significance precisely.
Delocalization, duality, and scaling in the quantum Hall system.

We construct an effective field theory for the quantum Hall system which embodies both localization and fractional statistics. The latter in­ volves a Chern-Simons interaction, while the former involves a general­ ization of conventional localization theory. The theory is invariant under "complexified" duality transformations of the conductivities which appear as effective parameters of the model. By exploiting these parameter space symmetries, as well as the conformal symmetry which-appears at renormal­ ization group fixed points, we are able to extract a precise prediction for the whole scaling dlagram. It exhibits both fractional and integer phases, the exact location of all fixed points, and universal scaling exponents. With a plausible identification of the universality class of the theory in the replica limit, the value of the critical exponent for the delocalization transition between plateaus in the Hall conductivity is found to be 7/3, in apparent agreement with available scaling experiments.
Wilderness and biodiversity conservation

Human pressure threatens many species and ecosystems, so conservation efforts necessarily prioritize saving them. However, conservation should clearly be proactive wherever possible. In this article, we assess the biodiversity conservation value, and specifically the irreplaceability in terms of species endemism, of those of the planet's ecosystems that remain intact. We find that 24 wilderness areas, all > 1 million hectares, are > 70% intact and have human densities of less than or equal to five people per km2. This wilderness covers 44% of all land but is inhabited by only 3% of people. Given this sparse population, wilderness conservation is cost-effective, especially if ecosystem service value is incorporated. Soberingly, however, most wilderness is not speciose: only 18% of plants and 10% of terrestrial vertebrates are endemic to individual wildernesses, the majority restricted to Amazonia, Congo, New Guinea, the Miombo-Mopane woodlands, and the North American deserts. Global conservation strategy must target these five wildernesses while continuing to prioritize threatened biodiversity hotspots.
MOLECULAR ORDERING IN MICROCONFINED LIQUID CRYSTALS : AN INFRARED LINEAR DICHROISM STUDY

Abstract The molecular arrangement of 5CB confined within the cylindrical pores of Anopore membranes was characterized by means of the IR-order parameter obtained from linear dichroism measurements of selected IR absorption bands. The treatment of the experimental data includes a local field correction extended to the twisted nematic configuration, yielding order parameters increased by about 30% in comparison with the uncorrected data. The nematic director of 5CB aligns along the pore axes, whereas in lecithin coated Anopore channels, the local nematic director is oriented approximately radially due to the perpendicular anchoring of the 5CB molecules at the pore wall. Doping of 5CB with the chiral agent CB15 yields local nematic directors tilted with respect to the pore axes. The average tilt angle increases up to about 40° at a fraction of CB15, x cb15 = 0.25 (w/w). These results are discussed in terms of the conical helicoidal and alternatively the radially twisted axial arrangement of the LC molecules.
Production of Lovastatin by Wild Strains of Aspergillus terreus

A wild fungal strain of Aspergillus terreus, labeled as PM3, was isolated by using the Candida albicans bioassay and confirmed by 18S r DNA analyses. Lovastatin was produced by submerged and solid state fermentations. Of the 30 isolated fungal strains, 11 showed lovastatin production with Aspergillus terreus PM3 being the best with a yield of 240 mg/L at the 10th day of submerged fermentation. Carboxymethylcellulose had a stimulatory effect on lovastatin production. It restricted uncontrolled filamentous growth, induced pellet formation and, thereby, improved lovastatin yield. In solid state fermentation (SSF), of the agro wastes from five crops (bran of wheat and rice, husks of red gram and soybean, and green gram straw), wheat bran showed maximum lovastatin production (12.5 mg/g of dry substrate) at pH 7.1 and a temperature of 30±2°C. Development of a lovastatin production process based on wheat bran as a substrate in SSF is economically attractive as it is a cheap and readily available raw material in agriculture-based countries.

A precise measurement method for the position of telescope's fiber tips

With the continuous development of multi-object fiber spectroscopic telescope, the integrated number of optical fibers on the focal plane is increasing, and these fibers should precisely align the celestial target when the astronomical observation is performing. Hence, the precise coordinates of the fiber tips are obligatory for tracking the celestial target. If the fiber positioning mechanism wants to accurately control fiber tips on the focal surface of the telescope, the movement trajectories of the fiber tips must be accurately measured in advance, so the fiber position measurement is the crucial problem. Based on the special structure of the LAMOST telescope and the composition of the initial position error, this paper aims at developing a high precision and robust measurement method by using bundle adjustment with a few control points.
Seven-Level Inverter Integrating Switched Capacitor Techniques

In this paper, a novel cascaded seven-level inverter topology with a single input source integrating switched capacitor techniques is presented. Compared with the traditional cascade multilevel inverter (CMI), the proposed topology replaces all the separate dc sources with capacitors, leaving only one H-bridge cell with a real dc voltage source and only adds two charging switches. The capacitor charging circuit contains only power switches, so that the capacitor charging time is independent of the load. The capacitor voltage can be controlled at a desired level without complex voltage control algorithm and only use the most common carrier phase-shifted sinusoidal pulse width modulation (CPS-SPWM) strategy. The operation principle and the chargingdischarging characteristic analysis are discussed in detail. A 1kW experimental prototype is built and tested to verify the feasibility and effectiveness of the
Geometric systematic prostate biopsy

Abstract Objective: The common sextant prostate biopsy schema lacks a three-dimensional (3D) geometric definition. The study objective was to determine the influence of the geometric distribution of the cores on the detection probability of prostate cancer (PCa). Methods: The detection probability of significant (>0.5 cm3) and insignificant (<0.2 cm3) tumors was quantified based on a novel 3D capsule model of the biopsy sample. The geometric distribution of the cores was optimized to maximize the probability of detecting significant cancer for various prostate sizes (20–100cm3), number of biopsy cores (6–40 cores) and biopsy core lengths (14–40 mm) for transrectal and transperineal biopsies. Results: The detection of significant cancer can be improved by geometric optimization. With the current sextant biopsy, up to 20% of tumors may be missed at biopsy in a 20 cm3 prostate due to the schema. Higher number and longer biopsy cores are required to sample with an equal detection probability in larger prostates. Higher number of cores increases both significant and insignificant tumor detection probability, but predominantly increases the detection of insignificant tumors. Conclusion: The study demonstrates mathematically that the geometric biopsy schema plays an important clinical role, and that increasing the number of biopsy cores is not necessarily helpful.
Adaptive intra prediction algorithm based on extended LARS

It is important to reduce intra prediction error for efficient image coding. However, as the existing methods are based on static structure model, there is no guarantee of their prediction efficiency for images whose structure model are unknown. To remedy the problem of existing methods, we formulate a linear prediction design problem with the goal of minimizing prediction error by placing sparsity constraints on the prediction coefficients. To solve the predictor design problem, we propose a novel method that extends Least Angle Regression(LARS). Coding gain of 1.01% to 2.24% is achieved over HM16.7.
Design of a highly efficient 1kW concentric wound IPM machine with a very wide constant power speed range

This paper presents a design process of a 1kW interior permanent magnet machine with concentrated non-overlapping windings. The main focus of this design is to achieve a very wide constant power speed range and optimal efficiency throughout the entire speed range. The authors will explain how the increase in airgap harmonic components caused by concentrated windings affects core and magnet losses; how the speed range is optimized and how losses are minimized by machine geometrical variations, construction strategies and appropriate selection of materials. Finite element analysis with transient and steady-state AC magnets in FLUX2D is used for predicting machine loss and field weakening performance due to its ability to handle complex calculations with non-linear material properties and precise geometry variations.
