AMASS: Archive of Motion Capture as Surface Shapes

Abstract: Large datasets are the cornerstone of recent advances in computer vision using deep learning In contrast, existing human motion capture (mocap) datasets are small and the motions limited, hampering progress on learning models of human motion While there are many different datasets available, they each use a different parameterization of the body, making it difficult to integrate them into a single meta dataset To address this, we introduce AMASS, a large and varied database of human motion that unifies 15 different optical marker-based mocap datasets by representing them within a common framework and parameterization We achieve this using a new method, MoSh++, that converts mocap data into realistic 3D human meshes represented by a rigged body model; here we use SMPL [doi:101145/28167952818013], which is widely used and provides a standard skeletal representation as well as a fully rigged surface mesh The method works for arbitrary marker sets, while recovering soft-tissue dynamics and realistic hand motion We evaluate MoSh++ and tune its hyperparameters using a new dataset of 4D body scans that are jointly recorded with marker-based mocap The consistent representation of AMASS makes it readily useful for animation, visualization, and generating training data for deep learning Our dataset is significantly richer than previous human motion collections, having more than 40 hours of motion data, spanning over 300 subjects, more than 11,000 motions, and will be publicly available to the research community

Integrating and Unifying Competing and Complementary Frameworks: The Search for a Common Core in the Business and Society Field

Abstract: In the field of business and society, several complementary frameworks appear to be in competition for preeminence. Although debatable, the primary contenders appear to include (a) corporate social responsibility, (b) business ethics, (c) stakeholder management, (d) sustainability, and (e) corporate citizenship. Despite the prevalence of the five frameworks, difficulties remain in understanding what each construct really means, or should mean, and how each might relate to the others. To address the confusion, the authors propose three core concepts—value, balance, and accountability—that might be used to better integrate the five frameworks and potentially provide the basis for further discussion and theoretical development of the business and society field.

Performance of pile-up mitigation techniques for jets in pp collisions at √s = 8 TeV using the ATLAS detector

Abstract: The large rate of multiple simultaneous protonproton interactions, or pile-up, generated by the Large Hadron Collider in Run 1 required the development of many new techniques to mitigate the advers ...

Globular adiponectin increases GLUT4 translocation and glucose uptake but reduces glycogen synthesis in rat skeletal muscle cells.

Abstract: The aim of this study was to determine whether adiponectin elicits glucose uptake via increased GLUT4 translocation and to investigate the metabolic fate of glucose in skeletal muscle cells treated with globular adiponectin. Basal and insulin-stimulated 2-deoxy-d-[3H]glucose uptake, cell surface myc-tagged GLUT4 content, production of 14CO2 by oxidation of d-[U-14C]glucose and [1-14C]oleate, and incorporation of d-[U-14C]glucose into glycogen and lactate were measured in the presence and absence of globular adiponectin. RT-PCR and Western blot analysis revealed that L6 cells and rat skeletal muscle cells express AdipoR1 mRNA and protein. Globular adiponectin increased both GLUT4 translocation and glucose uptake by increasing the transport V max of glucose without altering the K m. Interestingly, the incorporation of d-[U-14C]glucose into glycogen under basal and insulin-stimulated conditions was significantly decreased by globular adiponectin, whereas lactate production was increased. Furthermore, globular adiponectin did not affect glucose oxidation, but enhanced phosphorylation of AMP kinase and acetyl-CoA carboxylase, and fatty acid oxidation. The present study is the first to show that globular adiponectin increases glucose uptake in skeletal muscle cells via GLUT4 translocation and subsequently reduces the rate of glycogen synthesis and shifts glucose metabolism toward lactate production. These effects are consistent with the increased phosphorylation of AMP kinase and acetyl-CoA carboxylase and oxidation of fatty acids induced by globular adiponectin.

Mirrors of Masculinity: Representation and Identity in Advertising Images

Abstract: Through explication of a visual research method, this paper theorizes how masculine identity interacts with consumption - of imagery, products, desires, and passions in advertising and consumer culture. We analyze the male body as a discursive 'effect' created at the intersection of consumption and several marketing discourses such as advertising, market segmentation, and visual communication, balancing between brand strategy - what the marketer intends - and brand community - the free appropriation of meaning by the market. The paper's contribution rests in extending previous work on male representation into historical, ontological, and photographic realms, providing a necessary complement between understanding advertising meaning as residing within managerial strategy or wholly subsumed by consumer response. We argue that greater awareness of the connections between the traditions and conventions of visual culture and their impact on the production and consumption of advertising images leads to enhanced ability to understand how advertising works as a representational system and signifying practice.
