Background: Erionite has similar chemical and physical properties to amphibole asbestos, which induces autoantibodies in mice. Current exposures are occurring in North Dakota due to the use of erionite-contaminated gravel. While erionite is known to cause mesothelioma and other diseases associated with asbestos, there is little known about its effects on the immune system. Objectives: We performed this study to determine whether erionite evokes autoimmune reactions in mice. Methods: Bone marrow derived macrophages (BMDM) were used to measure toxicity induced by erionite. Cytokine production by BMDM and splenocytes of C57BL/6 mice was examined by bead arrays and ELISA following exposure to erionite, amphiboles and chrysotile. Wild type C57BL/6 mice were exposed to saline, erionite, amphibole asbestos (Libby 6-Mix) or chrysotile through intratracheal instillations at equal mass (60. μg/mouse). Seven months after exposure, sera were examined for anti-nuclear antibodies (ANA) and IL-17. Immunohistochemistry was used to detect immune complex deposition in the kidneys. Results: Erionite and tremolite caused increased cytokine production belonging to the TH17 profile including IL-17, IL-6, TGF-β, and TNF-α. The frequency of ANA was increased in mice treated with erionite or amphibole compared to saline-treated mice. IL-17 and TNF-α were elevated in the sera of mice treated with erionite. The frequency of immune complex deposition in the kidneys increased from 33% in saline-treated mice to 90% with erionite. Conclusions: These data demonstrate that both erionite and amphibole asbestos induce autoimmune responses in mice, suggesting a potential for adverse effects in exposed communities. © 2014 Elsevier Inc.

Good ensemble methods require accurate and diverse individual classifiers, but the relationship between the diversity of individual classifiers and the accuracy of an ensemble method is not clear. In this paper, we propose a novel model called COB (core, outlier, and boundary) to quantitatively measure the accuracies of majority voting ensembles for binary classification. In this model, we first divide data items into three subsets, core, outlier, and boundary, based on the prediction correctness of these items from individual classifiers in an ensemble method. Then we measure the accuracy of the ensemble method for each subset and combine the results together. We tested the performance of the COB model on 32 datasets from the UCI repository. The experiments use three different ensemble methods (bagging, random forests, and a randomized ensemble), two different numbers of individual classifiers (7 and 51), and three different individual machine learning algorithms (decision trees, k-nearest neighbors, and support vector machines). All 24 experiments showed less than 5% average absolute errors for 32 datasets between the accuracies by the COB model and the actual accuracies of ensembles. Also the experiments showed that the COB model performed significantly better than the binomial model. The COB model suggests that to achieve a high accuracy for an ensemble method, weak individual classifiers should be partly diverse instead of fully diverse, that is, be diverse on correctly predicted items but in agreement on some incorrectly predicted items. © 2012 IEEE.

Traditional moral philosophy has long focused on rationality, principled thinking, and good old-fashioned willpower, but recent evidence strongly suggests that moral judgments and prosocial behavior are more heavily influenced by emotion and intuition. As the evidence mounts, rational traditions emphasizing deliberative analysis and conscious decision making are called into question. The first section highlights some compelling evidence supporting the primacy of affective states in motivating moral judgments and behavior. The real challenge is finding a way to align intuition with desired behavior. In cool reflective states, one may desire to be a kind and loving person. But when it is time to act, the moment is often accompanied by strong affect-laden intuitions. I argue that if affective states are the primary motivators of behavior, then moral sentiments must be trained through habituation in order to increase prosocial behavior. The second section provides empirical evidence linking emotional training with increased prosociality. To highlight this connection, focus is placed on the relationship between habitual meditation training, compassion, and prosocial behavior. Recent studies by Antoine Lutz, Richard Davidson, Susanne Leiberg, and others show that various meditation practices can dramatically affect the human person at various levels, i.e., increased physical health, neural restructuring, regulation and development of emotions, and increased helping behavior, to name a few. The current article focuses on the impact the habit of loving-kindness meditation (LKM) has on compassion and prosocial behavior. Recent studies strongly support the conclusion that LKM training hones compassion and ultimately leads to an increase in compassionate behavior. © 2015, Springer Science+Business Media New York.

An experiment for analytical chemistry is presented that utilizes simultaneous thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) to characterize colorless, hydrated salts with anhydrous melting points less than 1100 C. The experiment could be used to supplement the lecture discussing gravimetric techniques. It is a straightforward experiment to introduce the instrumentation and analysis software to students, and it reinforces stoichiometric calculations. The students identify an unknown salt by determining the salt's water content using mass loss data from the TGA and by measuring the anhydrous salt's melting point using DSC data. © 2012 The American Chemical Society and Division of Chemical Education, Inc.

As a growing number of protein structures are resolved without known functions, using computational methods to help predict protein functions from the structures becomes more and more important. Some computational methods predict protein functions by aligning to homologous proteins with known functions, but they fail to work if such homology cannot be identified. In this paper we classify enzymes/non-enzymes using non-alignment features. We propose a new ensemble method that includes three support vector machines (SVM) and two k-nearest neighbor algorithms (k-NN) and uses a simple majority voting rule. The test on a data set of 697 enzymes and 480 non-enzymes adapted from Dobson and Doig shows 85.59% accuracy in a 10-fold cross validation and 86.49% accuracy in a leave-one-out validation. The prediction accuracy is much better than other nonalignment features based methods and even slightly better than alignment features based methods. To our knowledge, our method is the first time to use ensemble methods to classify enzymes/non-enzymes and is superior over a single classifier. © 2010 IEEE.

Electroshocking has long been employed as a survey technique for fish, but has not been directly tested against rock rolling as a survey methodology for stream-dwelling amphibians. Electroshocking has the potential to reduce habitat disturbances that result from surveys, improve abundance estimates, and reduce injuries and effort in collecting data. Furthermore, accurately quantifying species and survey techniquespecific estimates of detection probabilities is critical for appropriately interpreting survey results and employing occupancy analyses. We tested the efficiency and sensitivity of rock rolling and electroshocking in detecting Idaho giant salamanders (Dicamptodon aterrimus) in a small stream in northern Idaho, USA, by sampling short (25 m) segments of a stream using both survey techniques. We also conducted multi-pass surveys of 400-m stream segments to estimate detection probabilities for D. aterrimus and Rocky Mountain tailed frog (Ascaphus montanus). Using electroshocking, we detected D. aterrimus 40% more often than by rock rolling and detected 3.5 times as many individuals, with substantially reduced effort. Using electroshocking, detection probabilities were 1.0 for D. aterrimus and 0.79 (95% CI = 0.63-0.88) for A. montanus. Our results show electroshocking to be a much more sensitive and efficient method of detecting streamdwelling amphibians than the traditional technique of rock rolling. Electroshocking can serve as an important survey technique for secretive stream-dwelling amphibians, allowing managers to quickly and safely acquire valuable data of better quality. © 2012 The Wildlife Society.

Ensemble methods have been widely used to improve prediction accuracy over individual classifiers. In this paper, we achieve a few results about the prediction accuracies of ensemble methods for binary classification that are missed or misinterpreted in previous literature. First we show the upper and lower bounds of the prediction accuracies (i.e. the best and worst possible prediction accuracies) of ensemble methods. Next we show that an ensemble method can achieve > 0.5 prediction accuracy, while individual classifiers have < 0.5 prediction accuracies. Furthermore, for individual classifiers with different prediction accuracies, the average of the individual accuracies determines the upper and lower bounds. We perform two experiments to verify the results and show that it is hard to achieve the upper and lower bounds accuracies by random individual classifiers and better algorithms need to be developed. © 2010 IEEE.

CCAAT-enhancer binding proteins are transcription factors that help to regulate a wide range of inflammatory mediators, as well as several key elements of energy metabolism. Because C/EBPs are expressed by rodent astrocytes and microglia, and because they are induced by pro-inflammatory cytokines that are chronically upregulated in the Alzheimer's disease (AD) cortex, we have investigated whether C/EBPs are expressed and upregulated in the AD cortex. Here, we demonstrate for the first time that C/EBPβ can be detected by Western blots in AD and nondemented elderly (ND) cortex, and that it is significantly increased in AD cortical samples. In situ, C/EBPβ localizes immunohistochemically to microglia. In microglia cultured from rapid autopsies of elderly patient's brains and in the BV-2 murine microglia cell line, we have shown that C/EBPβ can be upregulated by C/EBP-inducing cytokines or lipopolysaccharide and exhibits nuclear translocation possibly indicating functional activity. Given the known co-regulatory role of C/EBPs in pivotal inflammatory mechanisms, many of which are present in AD, we propose that upregulation of C/EBPs in the AD brain could be an important orchestrator of pathogenic changes. © 2014 Strohmeyer et al.

The κ-nearest neighbors (κ-NN) algorithm is a widely used machine learning method that finds nearest neighbors of a test object in a feature space. We present a new exact κ-NN algorithm called κMκNN (κ-Means for κ-Nearest Neighbors) that uses the κ-means clustering and the triangle inequality to accelerate the searching for nearest neighbors in a high dimensional space. The κMκNN algorithm has two stages. In the buildup stage, instead of using complex tree structures such as metric trees, κd-trees, or ball-tree, κMκNN uses a simple κ-means clustering method to preprocess the training dataset. In the searching stage, given a query object, κMκNN finds nearest training objects starting from the nearest cluster to the query object and uses the triangle inequality to reduce the distance calculations. Experiments show that the performance of κMκNN is surprisingly good compared to the traditional κ-NN algorithm and tree-based κ-NN algorithms such as κd-trees and ball-trees. On a collection of 20 datasets with up to 106 records and 104 dimensions, κMκNN shows a 2- to 80-fold reduction of distance calculations and a 2- to 60-fold speedup over the traditional κ-NN algorithm for 16 datasets. Furthermore, κMκNN performs significant better than a κd-tree based κ-NN algorithm for all datasets and performs better than a ball-tree based κ-NN algorithm for most datasets. The results show that κMκNN is effective for searching nearest neighbors in high dimensional spaces. © 2011 IEEE.
