Cerebellar Gray Matter Volume, Executive Function, and Insomnia: Gender Differences in Adolescents
The cerebellum is an important region responsible for adolescent cognitive function and sleep, and their correlation is expected to show different patterns depending on age and gender. We examined the regional cerebellar gray matter volume (GMV), executive function (EF) and insomnia symptoms to identify their correlation and gender differences in adolescents. Data for a total of 55 subjects’ (M = 31, F = 24, 14.80 ± 1.39 years old) were analyzed. The correlations between cerebellar regional GMV and Wisconsin card sorting test (WCST) subcategories showed that EF was better with larger GMV both in males and females. Far more overall correlations with cerebellar regions were observed in boys, with corresponding correlation strength being higher, and differences in localization were also observed in contrast to girls. Larger cerebellar GMV corresponded to better EF in adolescents. Insomnia did not influence the correlations between cerebellar regional GMV and EF, but more severe insomnia in boys correlated to smaller GMV in the right flocculonodular lobe. These results might implicate that the adolescent cerebellum is involved differently in EF dependent on gender.

Swimming into trouble
\"As a member of the Vipers Swim Team, Julia Nam's always in the pool. Mountainview Community Center is like her second home, not only because swimming at the aquatic center is her favorite thing in the world, but also because her parents run the center's sushi café. She's the youngest swimmer on the team, but definitely not the slowest. Julia can't wait for Personal Best Day -- the most important day for all of the swimmers. If their times are good enough, they can enter a big regional swim meet. But then the worst thing happens. A sharp pain in Julia's ear reveals an infection and she's forbidden to swim for ten days. How can she get timed during Personal Best Day when she's not allowed in the water? Julia is desperate to get back in the pool, even if it means having to go behind her parents' backs in order to do so. But Julia's solution lands her in a sticky situation, and it's going to require the entire community center to come together to help her out of it!\"-- Provided by publisher.

An Improved Path-Finding Method for the Tracking of Centerlines of Tortuous Internal Carotid Arteries in MR Angiography
Centerline tracking is useful in performing segmental analysis of vessel tortuosity in angiography data. However, a highly tortuous) artery can produce multiple centerlines due to over-segmentation of the artery, resulting in inaccurate path-finding results when using the shortest path-finding algorithm. In this study, the internal carotid arteries (ICAs) from three-dimensional (3D) time-of-flight magnetic resonance angiography (TOF MRA) data were used to demonstrate the effectiveness of a new path-finding method. The method is based on a series of depth-first searches (DFSs) with randomly different orders of neighborhood searches and produces an appropriate path connecting the two endpoints in the ICAs. It was compared with three existing methods which were (a) DFS with a sequential order of neighborhood search, (b) Dijkstra algorithm, and (c) A* algorithm. The path-finding accuracy was evaluated by counting the number of successful paths. The method resulted in an accuracy of 95.8%, outperforming the three existing methods. In conclusion, the proposed method has been shown to be more suitable as a path-finding procedure than the existing methods, particularly in cases where there is more than one centerline resulting from over-segmentation of a highly tortuous artery.

5-LO-derived LTB4 plays a key role in MCP-1 expression in HMGB1-exposed VSMCs via a BLTR1 signaling axis
Monocyte chemoattractant protein-1 (MCP-1) plays an important role in initiating vascular inflammation; however, its cellular source in the injured vasculatures is unclear. Given the importance of high mobility group box 1 (HMGB1) in tissue injury, we investigated the role of vascular smooth muscle cells (VSMCs) in MCP-1 production in response to HMGB1. In primary cultured rat aortic VSMCs stimulated with HMGB1, the expression of MCP-1 and 5-lipoxygenase (LO) was increased. The increased MCP-1 expression in HMGB1 (30 ng/ml)-stimulated cells was significantly attenuated in 5-LO-deficient cells as well as in cells treated with zileuton, a 5-LO inhibitor. Likewise, MCP-1 expression and production were also increased in cells stimulated with exogenous leukotriene B4 (LTB4), but not exogenous LTC4. LTB4-induced MCP-1 expression was attenuated in cells treated with U75302, a LTB4 receptor 1 (BLTR1) inhibitor as well as in BLTR1-deficient cells, but not in 5-LO-deficient cells. Moreover, HMGB1-induced MCP-1 expression was attenuated in BLTR1-deficient cells or by treatment with a BLTR1 inhibitor, but not other leukotriene receptor inhibitors. In contrast to MCP-1 expression in response to LTB4, the increased MCP-1 production in HMGB1-stimulated VSMC was markedly attenuated in 5-LO-deficient cells, indicating a pivotal role of LTB4-BLTR1 signaling in MCP-1 expression in VSMCs. Taken together, 5-LO-derived LTB4 plays a key role in MCP-1 expression in HMGB1-exposed VSMCs via BLTR1 signaling, suggesting the LTB4-BLTR1 signaling axis as a potential therapeutic target for vascular inflammation in the injured vasculatures.

Ensemble-based face expression recognition approach for image sentiment analysis
Sentiment analysis based on images is an evolving area of study. Developing a reliable facial expression recognition (FER) device remains a difficult challenge as recognizing emotional feelings reflected in an image is dependent on a diverse set of factors. This paper presented an ensemble-based model for FER that incorporates multiple classification models: i) customized convolutional neural network (CNN), ii) ResNet50, and iii) InceptionV3. The model averaging ensemble classifier method is used to ensemble the predictions from the three models. Subsequently, the proposed FER model is trained and tested on a dataset with an uncontrolled environment (FER-2013 dataset). The experiment demonstrated that ensembling multiple classifiers outperformed all single classifiers in classifying positive and neutral expressions (91.7%, 81.7% and 76.5% accuracy rate for happy, surprise, and neutral, respectively). However, when classifying disgust, anger, and sadness, the ResNet50 model alone is the better choice. Although the Custom CNN performs the best in classifying fear expression (55.7% accuracy), the proposed FER model can still classify fear expression with comparable performance (52.8% accuracy). This paper demonstrated the potential of using the ensemble-based method to enhance the performance of FER. As a result, the proposed FER model has shown a 72.3% accuracy rate.

James Turrell : a retrospective
\"Published in conjunction with a major retrospective, this comprehensive volume illuminates the origins and motivations of James Turrell's incredibly diverse and exciting body of work--from his Mendota studio days to his monumental work-in-progress Roden Crater. Whether he's projecting shapes on a flat wall or into the corner of a gallery space, James Turrell is perpetually asking us to \"go inside and greet the light\"--evoking his Quaker upbringing. In fact, all of Turrell's work has been influenced by his life experiences with aviation, science, and psychology, and as a key player in Los Angeles's exploding art scene of the 1960s. Enhanced by thoughtful essays and an illuminating interview with the artist, this monograph explores every aspect of Turrell's career to date--from his early geometric light projections, prints, and drawings, through his installations exploring sensory deprivation and seemingly unmodulated fields of colored light, to recent two-dimensional experiments with holograms. It also features an in-depth look at Roden Crater, a site-specific intervention into the landscape near Flagstaff, Arizona, which will be presented through models, plans, photographs, and drawings. Fans of this highly influential artist will find much to savor in this wide-ranging and beautiful book, featuring specially commissioned new photography by Florian Holzherr.\"--Publisher's website.

Gender and Communication in Euripides' Plays
In Greek tragedy, women constantly struggle to control language. This book shows how aspects of women's communication--song, silence and secret-keeping as female verbal genres, and the challenges of speaking out of place--constitute a decisive factor in Euripides' portrayal of gender.
