Classification of Dynamic Contrast Enhanced MR Images of Cervical Cancers Using Texture Analysis and Support Vector Machines

Dynamic contrast enhanced MRI (DCE-MRI) provides insight into the vascular properties of tissue. Pharmacokinetic models may be fitted to DCE-MRI uptake patterns, enabling biologically relevant interpretations. The aim of our study was to determine whether treatment outcome for 81 patients with locally advanced cervical cancer could be predicted from parameters of the Brix pharmacokinetic model derived from pre-chemoradiotherapy DCE-MRI. First-order statistical features of the Brix parameters were used. In addition, texture analysis of Brix parameter maps was done by constructing gray level co-occurrence matrices (GLCM) from the maps. Clinical factors and first- and second-order features were used as explanatory variables for support vector machine (SVM) classification, with treatment outcome as response. Classification models were validated using leave-one-out cross-model validation. A random value permutation test was used to evaluate model significance. Features derived from first-order statistics could not discriminate between cured and relapsed patients (specificity 0%-20%, p-values close to unity). However, second-order GLCM features could significantly predict treatment outcome with accuracies (~70%) similar to the clinical factors tumor volume and stage (69%). The results indicate that the spatial relations within the tumor, quantified by texture features, were more suitable for outcome prediction than first-order features.
Characterization of microbial community in nitrogen removal process of metallurgic wastewater by PCR-DGGE.

The metallurgic wastewater generated from the processes of recovering precious metals from industrial wastes contains high concentrations of nitrogen compounds such as ammonia and nitric acid and of salts such as sodium chloride and sodium sulfate. Biological nitrogen removal from this wastewater was attempted by a circulating bioreactor system equipped with an anoxic packed bed and an aerobic fluidized bed. The anoxic packed bed of this system was found to effectively remove nitrite and nitrate from the wastewater by denitrification at a removal ratio of 97%. As a result of denitrification activity tests at various NaCl concentrations, the sludge obtained from the anoxic packed bed exhibited accumulation of nitrite at 5.0 and 8.4% NaCl concentrations, suggesting that the reduction of nitrite is the key step in the denitrification pathway under hypersaline conditions. The microbial community analysis by denaturing gradient gel electrophoresis (DGGE) of PCR-amplified 16S ribosomal DNA (rDNA) fragments revealed that the community diversity varied in accordance with water temperature, nitrate-loading rate and ionic strength. When particular major DGGE bands were excised, reamplified and directly sequenced, the dominant species in the anoxic packed bed were affiliated with the beta and gamma subclasses of the class Proteobacteria such as Alcaligenes defragrans and Pseudomonas spp. , respectively.
Removal of methyl red from aqueous solution by activated carbon prepared from the Annona squmosa seed by adsorption

The use of low-cost, locally available, highly efficiencient and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. This study investigates the potential use of activated carbon prepared from the Annona squmosa seed for the removal of methyl red (MR) dye from simulated wastewater. The effects of different system variables, adsorbent dosage, initial dye concentration, pH and contact time were investigated and optimal experimental conditions were ascertained. The results showed that as the amount of the adsorbent increased, the percentage of dye removal increased accordingly. Optimum pH value for dye adsorption was 7.0. Maximum dye was sequestered within 50 min of the start of every experiment. The adsorption of methylene blue followed the pseudo-second –order rate equation and fits the Langmuir, Freundlich, Dubinin-Radushekevich (D-R) and Tempkin equations well. The maximum removal of MR was obtained at pH 7 as 82.81% for adsorbent dose of 0.2 g/ 50 mL and 25 mg L -1 initial dye concentration at room temperature. Furthermore, adsorption kinetics of MR was studied and the rate of adsorption was found to conform to pseudo-second –order kinetics with a good correlation (R 2 > 0.99) with intraparticle diffusion as one of the rate determining steps. Activated carbon developed from the Annona squmosa seed can be an attractive option for dye removal from diluted industrial effluents since test reaction made on simulated dyeing wastewater showed better removal percentage of MR.

Detection of asystole, ventricular fibrillation and ventricular tachycardia with automated ECG monitoring.

The performance of an automated arrhythmia monitoring system has been studied with reference to asystole, ventricular fibrillation (VF) and ventricular tachycardia (VT) during two periods of routine monitoring. The system distinguished normal, supraventricular and ventricular ectopic beats with the use of rhythm and QRST data. VF was recognized from the power spectrum of the ECG. A total of 17 arrhythmia diagnoses (alarms) could be made by the system. A write-out, with a delayed ECG and a diagnostic message in parallel, was recorded at each alarm. In the first part of the study a continuous ECG, used as a reference, was recorded from all patients in the coronary care unit during a 4-week period. The number of manually recorded episodes of asystole, VF and VT was 24, 4 and 44, respectively. Out of these, 92, 100 and 82%, respectively, were reproduced on the alarm write-outs. A correct diagnosis was made by the automated system in 33, 75 and 70% of true asystole, VF and VT events, respectively. Three false asystole alarms, all due to loose electrodes, were reported during this part of the study. In the second part of the study all arrhythmia write-outs were analysed for six months for the occurrence of VF and VT alarms. Out of 22 episodes of VF, 73% were reported as VF and the remaining as VT. Of 534 VT episodes, 82% were diagnosed correctly. The proportions of correct: false positive VF and VT detections were approximately 1: 5 and 4: 1. Compared with conventional monitoring, the automated system seems to specifically improve the detection rate of VT.
Evaluation of validity of British anthropometric reference data for assessing nutritional state of elderly people in Edinburgh: cross sectional study

Abstract Objectives:To evaluate the appropriateness of two sets of commonly used anthropometric reference data for nutritional assessment of elderly people. Design:Cross sectional study. Setting:Two general practices in Edinburgh. Subjects:200 independently living men and women aged 75 or over randomly recruited from the age and sex register of the practices. Main outcome measures:Weight (kg), knee height (cm), demispan (cm), mid-upper arm circumference (cm), triceps skinfold thickness (mm), arm muscle circumference (cm) body mass index (kg/m2), and demiquet (kg/m2) in men and mindex (kg/m) in women. Results:Men and women in Edinburgh were significantly shorter than those in measured for the Nottingham reference data (demispan 0.79 v 0.80 (P<0.05) for men and 0.72 v 0.73 (P<0.01) for women). Comparison with data from South Wales showed that men and women from Edinburgh had significantly greater mid-upper arm circumference, triceps skinfold thickness, and arm muscle circumference. No one fell below the 10th centile of the South Wales data (the commonly used cut off point for determining malnutrition) for these measures. Conclusions:Both sets of reference data commonly used in Britain may be inappropriate for nutritional screening of elderly people in Edinburgh. Contemporary reference data appropriate for the whole of Britain need to be developed, and in the longer term biologically or clinically defined criteria for undernutrition should be established. Key messages Anthropometric reference data for assessing the nutrition of elderly people in Britain are limited This Edinburgh population showed significant differences from the commonly used reference data in several anthropometric measures Existing anthropometric reference data could lead to significant biases when used for screening for undernutrition or determining prevalence of malnutrition
Numerical analysis of sandwiched composite-FSS structures

A numerical technique to analyze shielding effectiveness of sandwiched FSS-composite structures is proposed. This technique is based on using a dispersive FDTD method in conjuncture with a novel periodic boundary condition to model sandwiched FSS-composite elements. Results show that by inserting single or multilayered FSS elements into composite materials, better shielding effectiveness can be achieved.

Influence of halothane on electrical coupling in cell pairs isolated from guinea‐pig ventricle

1 The actions of halothane on electrical coupling between cells were investigated in cell pairs isolated from guinea‐pig ventricular muscle. 2 Under voltage‐clamp conditions a step depolarization applied to one cell caused a similar change in potential in the second. Application of halothane led to the appearance of double peaks in inward current evoked by step depolarizations. These observations were interpreted in terms of uncoupling of the cells leading to escape of the second cell from the influence of the voltage‐clamp in the first cell. 3 This suggestion that uncoupling in the presence of halothane led to differences in electrical activity in the two cells was confirmed in experiments in which independent electrodes were used to measure membrane potential in the two cells. 4 The voltage responses of both cells of the pair were recorded in response to constant current pulses. Administration of halothane led to abolition of the response recorded from the second cell while that of the first was enhanced. The actions are consistent with an action of halothane on gap junctions to block electrical coupling. 5 Qualitatively similar observations, consistent with electrical uncoupling, were observed with isoflurane. 6 These findings may be significant in relation to the arrhythmogenic actions of halothane.
Risk factors for mortality in 137 pediatric cardiac intensive care unit patients managed with extracorporeal membrane oxygenation*

ObjectiveTo identify factors associated with mortality in children with heart disease managed with extracorporeal membrane oxygenation (ECMO). DesignRetrospective chart review. SettingTertiary care university-affiliated children’s hospital. PatientsAll pediatric cardiac intensive care unit patients managed with ECMO between January 1, 1995, and June 30, 2001. InterventionsNone. ResultsDuring the study period, 137 patients were managed with ECMO in the pediatric cardiac intensive care unit. Of the 137 patients, 80 (58%) survived ≥24 hrs after decannulation, and 53 (39%) survived to hospital discharge. Patients managed with ECMO following cardiac surgery were analyzed separately from patients not in the postoperative period. Factors associated with an increased probability of mortality in the postoperative patients were age <1 month, male gender, longer duration of mechanical ventilation before ECMO, and development of renal or hepatic dysfunction while on ECMO. Single ventricle physiology and failure to separate from cardiopulmonary bypass were not associated with an increased risk of mortality. Cardiac physiology and indication for ECMO were not associated with mortality rate. Although longer duration of ECMO was not associated with increased mortality risk, patients with longer duration of ECMO were less likely to survive without heart transplantation. ConclusionsIn a series of 137 patients managed with ECMO in a pediatric cardiac intensive care unit, survival to hospital discharge was 39%. In postoperative patients only, mortality risk was increased in males, patients <1 month old, patients with a longer duration of mechanical ventilation before initiation of ECMO, and patients who developed renal or hepatic failure while on ECMO.
Efficient green solution for a balanced energy consumption and delay in the IoT-Fog-Cloud computing

This paper introduces a study of the fog computing suitability assessment as a solution for the increasing demand of the IoT devices. In particular, we focus on the energy consumption and the Quality of Service (QoS) as two important metrics of the performance of the fog. Therefore, we present a modeling of these two metrics in the fog. Then, we express the problem as constrained optimization and solve it efficiently using Evolutionary Algorithms (EA). Our approach stands out as an energy-efficient solution.
Perception Accuracy of Biases in Self and in Others

Three studies showed that the group of observers accurately recognized biases in other people’s behaviors while the group of actors was unable to detect the same biases in their own behaviors. The logic and inevitability of biases influenced the estimations of the former. Biases which were positive, beneficial, logical and non-threatening for the self but at the same time uncontrollable were perceived as more accurate by the group of actors. The correlations among the characteristics of biases themselves and between characteristic of biases and the accuracy are suggested as possible explanations. The theoretical background of the studies is embodied as well in tendency-oriented theories (Kahneman & Tversky, 1973; Fiske & Taylor, 1984; Kruglansky, 1989) as in new stream of accuracy theories (Haselton & Buss, 2000; Funder, 1995; Levesque, 1997; Simson, Ickes, & Grich, 1999).
Reflex sympathetic dystrophy syndrome.

Nine patients with reflex sympathetic dystrophy were examined. Clinical manifestations suggesting arthropathy were supported by radiographic demonstration of juxta-articular and subchondral bone erosions and by radionuclide demonstration of increased activity localized in the joint regions. Aggressive demineralization was demonstrated by fine-detail radiography and consisted of endosteal and intracortical excavation and subperiosteal and trabecular bone resorption. A one-third reduction in bone mineral was confirmed by quantitative analyses. Newer modalities of study have aided in the documentation of arthropathy in reflex sympathetic dystrophy and have helped in defining the patterns of aggressive bone resorption.

The design of a millimeter wave n x n array antenna at 60 GHz with corporate feed network printed on the same side of the substrate is presented. The antenna is designed using transmission line model and simulated using IE3D software. Simulation and measured results were in good agreement. Analyses were carried out for 2x2, 4x4, 8x8 arrays. The gain and beam width of 8x8 microstrip array is 18.48 dBi and 10.49 deg. The 10 dB return loss bandwidth spans from 59 GHz to about 61 GHz. The proposed array can be integrated with the existing MMIC’s or wireless equipment with suitable selection of the substrate.
Molecular basis of the structural stability of hemochromatosis factor E: A combined molecular dynamic simulation and GdmCl‐induced denaturation study

Hemochromatosis factor E (HFE) is a member of class I MHC family and plays a significant role in the iron homeostasis. Denaturation of HFE induced by guanidinium chloride (GdmCl) was measured by monitoring changes in [θ]222 (mean residue ellipticity at 222 nm), intrinsic fluorescence emission intensity at 346 nm (F346) and the difference absorption coefficient at 287 nm (Δε287) at pH 8.0 and 25°C. Coincidence of denaturation curves of these optical properties suggests that GdmCl‐induced denaturation (native (N) state ↔ denatured (D) state) is a two‐state process. The GdmCl‐induced denaturation was found reversible in the entire concentration range of the denaturant. All denaturation curves were analyzed for ΔGD0 , Gibbs free energy change associated with the denaturation equilibrium (N state ↔ D state) in the absence of GdmCl, which is a measure of HFE stability. We further performed molecular dynamics simulation for 40 ns to see the effect of GdmCl on the structural stability of HFE. A well defined correlation was established between in vitro and in silico studies. © 2015 Wiley Periodicals, Inc. Biopolymers 105: 133–142, 2016.
A NON-ARISTOTELIAN SYSTEM AND ITS NECESSITY FOR RIGOUR IN MATHEMATICS AND PHYSICS

A very extensive literature shows that the problems of ‘infinity’ pervade human psycho-logical reactions, starting from the lowest stage of human development up to the present and that without some theory of ‘infinity’, modern mathematics would be impossible. Up to date, no satisfactory theory of infinity, on which all mathematicians could agree, has been produced. The results are rather bewildering because what appears to some prominent mathematicians as perfectly sound mathematics is evaluated by other equally prominent scientists as a ‘mental’ disease (Poincaré); or we find opinions that a large portion of mathematics is devoid of proof and has to be accepted on faith; or that some parts of mathematics must be treated as non-sense (Kronecker, Brouwer, Weyl. ,). ‘There are eminent scholars on both sides and the chance of reaching an agreement within a finite period is practically excluded’, says Brouwer, and certainly such a state of affairs does not allow us to have any satisfactory modern standards of proof and rigour; the last thing we should expect in mathematics. The majority of those mathematicians who take interest in the soundness of their science seem to believe that the main difficulty centres around the validity of the ‘law of excluded third’ (‘A is B. or not B’) of the accepted, sharply two-valued, chrisippian form of A ‘logic’. They disregard the fact that we are born, bred, educated, speak a language, live under conditions, institutions. , which still remain desperately A or even pre-aristotelian. If we attempt to reject one of the two-valued ‘laws of thought’ or postulates of the A-system but retain A or pre-aristotelian elementalistic ‘psychologies’, ‘logic’, and s.r, no agreement in ‘a finite period’ can be expected, and the present mathematical chaos would continue.
A novel nuclear pore protein Nup133p with distinct roles in poly(A)+ RNA transport and nuclear pore distribution.

Temperature‐sensitive nucleoporin nup49‐316 mutant cells accumulate poly(A)+ RNA inside the nucleus when shifted to restrictive temperature. We performed a synthetic lethal screen with this mutant allele to identify further components of the mRNA export machinery. A synthetic lethal mutant slv21 was isolated, which exhibited a ts phenotype and showed nuclear accumulation of poly(A)+ RNA at 37 degrees C. The wild‐type gene complementing slv21 was cloned and sequenced. It encodes a novel protein Nup133p which is located at the nuclear pore complex. NUP133 is not an essential gene, but cells in which NUP133 is disrupted grow slowly at permissive temperatures and stop growing at 37 degrees C. Concomitant with the growth inhibition, nup133‐ cells accumulate poly(A)+ RNA inside the nucleus whereas nuclear import of a karyophilic reporter protein is not altered. Strikingly, nup133‐ cells display extensive clustering of nuclear pore complexes at a few sites on the nuclear envelope. However, the nuclear pore clustering phenotype and intranuclear accumulation of poly(A)+ RNA are not obligatorily linked, since an amino‐terminally truncated Nup133p allows normal poly(A)+ RNA export, but does not complement the clustering phenotype of nup133‐ cells.
Work Experiences and Tobacco Use: Findings From the Gear Up for Health Study

Objective: To examine the relationships between the work environment and amount smoked, intention to quit, and participation in a health promotion intervention. Methods: Cross-sectional data were collected from unionized truck drivers and dockworkers (N = 542; response rate = 78%) employed in eight trucking terminals as part of a larger intervention study targeting tobacco use cessation and weight management. Results: Prevalence of tobacco use was 40% (n = 216). Multivariable analyses of amount smoked and coworker norms encouraging cessation found significant associations with intention to quit and negative social consequences of tobacco use. Program participation was significantly associated with concern about job exposures, working the day shift, and intention to quit. Conclusions: Work experiences represented in the social contextual model may help explain how the work environment affects tobacco-use behaviors and interest in quitting, and maybe guide interventions among blue-collar workers.
Fuzzy Modeling for Multi-Label Text Classification Supported by Classification Algorithms

The ever-increasing amount of information on the Web is organized in structured, semi-structured and unstructured data. Text classification systems, capable of handling such different structures, may facilitate the work of important tasks such as indexation and information retrieval in search engines. The objective of this research is to develop a method for the classification of documents into multiple categories with fuzzy logic. This method was built from a process of pattern recognition and, also, two variables called similarity and accuracy were used. The proposed fuzzy classification method uses variables that express the ability to analyze the similarity and accuracy of a document through a database of terms. The database of terms is generated by a collection of pre-classified documents in categories of interest. The documents processed according to the similarity and accuracy in the database of terms composes a training set also called knowledge base. From this database, it is possible to identify a pattern that specifies a set of rules through a knowledge discovery process. This process involves the data mining of the knowledge base. Thus, it was possible to define a general model that is used in the creation of rules and membership functions of the fuzzy model for the classification of documents into multiple categories. The general model of the rules identified in the data mining process and implemented in fuzzy model considers the most significant variables and also contributes to the specification of the membership functions, such as the definition of linguistic terms of fuzzy sets. Thus, it was possible to implement a more deterministic approach regarding the input, membership functions and inference rules of the fuzzy model. The results of the proposed method for classification of documents are relevant because they have a satisfactory accuracy rate.
Characterizing Spatial Parameters of Forest Canopies Using Fisheye Photography: Applications in Photo Ecometrics

Abstract Five case studies are presented that demonstrate how metrics inferred from canopy photography can inform and validate the results from digital aerial photography and other remote sensing platforms. The forests measured include evergreen and deciduous canopies composed of both needle-leaved and broad-leaved tree species. Gap fractions of these forest canopies ranged from 3% to 22%. Significant fine-scale spatial autocorrelation of canopy structure was detected in two subalpine forests. In a conifer-hardwood forest, the canopy opening associated with the stream course still influenced understory light availability 45 m from the stream bank. In contrast, there was no correspondence between distance from the stream and canopy architecture in two Tsuga-dominated ravines. Forest stands classified as the same vegetation type and considered replicated sites in field experiments can have significant differences in some canopy metrics. The results from these ecological studies have direct relevance to the .
