"Tea with Crows" is a motion interactive sculpture composed of a shape-shifting tea table and a kinetic chandelier. It combines visually intriguing aesthetics and multimodal technology such as motion and sound interaction to stimulate audience participation. The sculpture also evokes a wide array of subjective responses, fosters social interaction, and creates meaning-making experiences. The empowering effect of the sculpture opens the possibility to adopt, reinterpret, and de familiarize digital technology to extend imagination, self-expression and subjective purpose.

"Tea with Crows" is an interactive sculptural installation seeking to enable a poetic use of technology that offers stimulation and provocation. It does so by embedding aesthetic elements, experimental ideas and practical usage into ubiquitous computing. This multi-modal interactive piece connects people to each other, and constructs social conversation while engaging in innovative ambient design and technology. "Tea with Crows" explores experiential aesthetic by embedding playful kinetic motion and shape changing interfaces into everyday objects. The transformable form, function, and action of the sculpture are synchronized between the tea table and chandelier enriching the human experience. Ultimately, "Tea with Crows" aims to bring an expressive digital object with ubiquitous computing into the foreground of our everyday life by creating proactive interaction beyond the calm display.

Intermittent-flow respirometry is an experimental protocol for measuring oxygen consumption in aquatic organisms that utilizes the best features of closed (stop-flow) and flow-through respirometry while eliminating (or at least reducing) some of their inherent problems. By interspersing short periods of closed-chamber oxygen consumption measurements with regular flush periods, accurate oxygen uptake rate measurements can be made without the accumulation of waste products, particularly carbon dioxide, which may confound results. Automating the procedure with easily available hardware and software further reduces error by allowing many measurements to be made over long periods thereby minimizing animal stress due to acclimation issues. This paper describes some of the fundamental principles that need to be considered when designing and carrying out automated intermittent-flow respirometry (e.g. chamber size, flush rate, flush time, chamber mixing, measurement periods and temperature control). Finally, recent advances in oxygen probe technology and open source automation software will be discussed in the context of assembling relatively low cost and reliable measurement systems. © 2016 The Fisheries Society of the British Isles.

This paper examines the variations in dog owners' attitudes toward, treatment of, and interactions with, animals. Based on 28 in-depth interviews with dog owners from a county in the Midwestern United States, I demonstrate that pets are an important part of many people's lives, often providing companionship, entertainment, and meaningful interactions; however, there are notable, distinct variations in how people relate to them. Pet owners typically exhibit one of three orientations toward pets: "dominionistic," "humanistic," or "protectionistic." The dominionistic have relatively low regard for their pets, valuing them primarily for the uses they provide, such as protection. Those employing the humanistic orientation elevate their pets to the status of surrogate humans and value their pets primarily for the affective benefits they enjoy from their close attachments. The protectionistic have high regard for both pets and animals more generally. They view pets as valuable companions and as creatures with their own interests. This typology offers insights for understanding the source and variety of the often ambiguous and contradictory relations between people and pets. I argue that individual characteristics and experiences impact how people understand and relate to animals, in large part, because they represent exposure to different cultural messages. I suggest that these orientations represent three sets of distinct cultural logics, each with distinct histories and contemporary sources. © ISAZ 2013.

The program of constructing spacetime geometry from string theoretic modular forms is extended to Calabi-Yau varieties of dimensions three and four, as well as higher rank motives. Modular forms on the worldsheet can be constructed from the geometry of spacetime by computing the L-functions associated to omega motives of Calabi-Yau varieties, generated by their holomorphic n-forms via Galois representations. The modular forms that emerge in this way are related to characters of the underlying rational conformal field theory. The converse problem of constructing space from string theory proceeds in the class of diagonal theories by determining the motives associated to modular forms in the category of pure motives with complex multiplication. The emerging picture suggests that the L-function can be viewed as defining a map between the geometric category of motives and the category of conformal field theories on the worldsheet. © 2011 Springer-Verlag.

Hydrogen sulfide (H2S) has become the hot new signaling molecule that seemingly affects all organ systems and biological processes in which it has been investigated. It has also been shown to have both proinflammatory and anti-inflammatory actions and proapoptotic and anti-apoptotic effects and has even been reported to induce a hypometabolic state (suspended animation) in a few vertebrates. The exuberance over potential clinical applications of natural and synthetic H2S-"donating" compounds is understandable and a number of these function-targeted drugs have been developed and show clinical promise. However, the concentration of H2S in tissues and blood, as well as the intrinsic factors that affect these levels, has not been resolved, and it is imperative to address these points to distinguish between the physiological, pharmacological, and toxicological effects of this molecule. This review will provide an overview of H2S metabolism, a summary of many of its reported "physiological" actions, and it will discuss the recent development of a number of H2S-donating drugs that show clinical potential. It will also examine some of the misconceptions of H2S chemistry that have appeared in the literature and attempt to realign the definition of "physiological" H2S concentrations upon which much of this exuberance has been established. © 2011 the American Physiological Society.

To visually illustrate the impact of architecture and communication on parallel computing we created a model supercomputer in the spirit of other engineering models. Combining Raspberry Pi computers with an NVIDIA TK1 the resulting machine is distinguished by it's instructional utility, asymmetric CPU and communication channel speed, and for incorporating current trends in heterogeneous supercomputing. Running Linux, the model supports major high-performance computing software environments, including OpenMP, MPI, and NVIDIA's CUDA. The model architecture includes aspects of heterogeneous, supercomputers such as shared- and distributed-memory MIMD, and 192 CUDA core SIMD-like processors. © 2015 IEEE.

A framework of inflation is formulated based on symmetry groups and their associated automorphic functions. In this setting the inflaton multiplet takes values in a curved target space constructed from a continuous group G and a discrete subgroup Γ. The dynamics of inflationary models is essentially determined by the choice of the pair (G, Γ) and a function Φ on the group G. Automorphic inflation provides a natural structure in which the shift symmetry of large field inflation arises as one of generators of Γ. The model of j-inflation is discussed as an example of modular inflation associated with the special linear group. © 2015.

Despite the widespread adoption of e-procurement by firms in recent years, academic research examining the mechanisms through which e-procurement applications lead to performance has been scarce. Anecdotal evidence points to numerous situations where companies have failed to harness the potential of e-procurement. In this paper, we argue that online purchase volume and mix flexibilities facilitated by these applications play a significant role in the ability of firms to benefit from e-procurement. We examine this tenet from both an economic as well as a social perspective. We propose that increased online purchase volume flexibility as well as online purchase mix flexibility can be facilitated by two mechanisms - supplier customization as explained by transaction costs perspective, and information sharing between supply chain partners using a social exchange theoretical perspective. The increased purchase volume and mix flexibility in turn leads to better performance along the dimensions of cost, quality, and delivery. We present and test a nuanced perspective where we argue that (i) the effect of supplier customization on both purchase volume and mix flexibilities will be moderated by the frequency of transactions conducted online, and (ii) the effect of information sharing on both purchase volume and mix flexibilities will be moderated by trust in the supplier. We estimate our research model using survey data collected from 130 purchasing and procurement managers. We find strong support for our proposed research model with results indicating that purchase volume and mix flexibilities play a vital mediating role in impacting e-procurement performance. Theoretical and practical implications of the findings are discussed. © 2012 Elsevier B.V.

South Bend’s Lunkerville, the award-winning TV series that catches real people with real fish stories, is proud to once again feature Heroes On The Water (HOW), a non-profit organization dedicated to helping military veterans relax, rehabilitate, and reintegrate through kayak fishing. This season’s all new episode has series host ‘Mike D’ traveling to Lake Denmark, New Jersey, to fish with war veteran Justin Vail from the New Jersey Chapter of Heroes On The Water. The show will air Thursday, February 23 at 9 AM, and Friday, February 24 at 1 AM, 9 AM and 3 PM on World Fishing Network. The South Bend brand is excited to continue its partnership with Heroes On The Water as it directly aligns with the brand’s core message: that fishing is an experience unlike any other, in that it combines an exciting sport and a tranquil natural setting, to provide a backdrop for lifelong memories with friends and family. As Vail’s firsthand account with Heroes On The Water illustrates, it’s precisely this kind of experience that has proven to be so useful as part of a treatment regime that helps veterans and their families reconnect and transition to healthier lives. “Heroes On The Water is an incredible resource for our nation’s veterans,” explains Scott Griffith, Vice President of Marketing for South Bend. “They literally change the lives of those who have served our country, as this year’s episode dramatically illustrates. And the way they do it is through the simple experience of kayak fishing. It almost sounds far-fetched, but the truth is that this kind of fishing combines a positive and empowering physical experience with the emotional and spiritual benefits of being in a peaceful natural setting. The results speak for themselves: HOW has documented a 56% decrease in overall stress levels in participating veterans, as well as significant reductions in other combat-related symptoms like avoidance behavior and hyper-vigilance.” “It made perfect sense for South Bend’s Lunkerville to revisit Heroes On The Water again in 2017,” said series host and creator, Mike D. “Viewers loved the show we did last season — the response was overwhelming and personally, it’s always an emotional and inspiring experience fishing with these guys. HOW deserves all the recognition we can give them.” Through the remainder of 2017, check local listings for additional airings of this episode on CBS Sports Network, World Fishing Network and beginning in April, Destination America, as well as for information on the ever-expanding list of broadcast partners and regional affiliate stations, including Comcast Sports networks, Time Warner Sports channels and PBS stations.
