The Drake Relays are one of the iconic events of track and field in the United States. World and Olympic champions test their speed and stamina on the famed Blue Oval in Des Moines, Iowa, every April, and by spring 2013 they had set fourteen world records and fifty-one American records. But unlike most other top meets, this one also features college athletes from all over the country and high school athletes from across Iowa, giving them the experience of (...) a lifetime—competing on the same track with the elite in their sport. This mix brings many enthusiastic spectators to the stadium and makes for an unusually close bond between fans and athletes—it’s as if everyone’s family is there cheering. Pulitzer Prize–winning photographer David Peterson has been covering the Drake Relays for nearly forty years, but his love affair with the meet started earlier, when he ran on three winning relay teams there for Kansas State University. Now, drawing upon an unmatched personal archive, he offers the pictures of a lifetime spent on the Blue Oval. He captures on camera athletes of all levels in triumph and defeat, in mid-stride or leap, embracing their fans, their moms and dads, and their kids. In addition to the stars of the past, such as Carl Lewis, Suzy Favor Hamilton, and Herschel Walker, and those of the ’00s, like Lolo Jones and Jeremy Wariner, we see teenagers who may be the stars of the future, as well as the many athletes who will never be famous but nonetheless show themselves—and their sport—at their best. A beautiful celebration of the Drake Relays and the diverse sports that make up “track and field,” this book will evoke memories and inspire runners, throwers, and jumpers everywhere. (shrink)

The present paper looks at the intersection of juridical and biopower in the U.S. Supreme Court’s school desegregation cases. These cases generally deploy “equitable relief” as a relay between the juridicially-specified injury of segregation and the biopolitical mandates of integration, allowing broad-based biopolitical remedies for juridically identified problems. This strategy enabled the Courts to negotiate between these forms of power. The analysis here thus suggests the continued relevance of juridical power, and also the limits of Foucault’s own analysis, which suggested (...) that biopower tended to fully colonize juridical power by way of norms.

The author claims that the social relay theory rose from the global problem of the mode of existence of semiotic objects (including knowledge). This problem is connected with the status of text in human studies and epistemology that is both the material phenomenon (sound oscillation, ink on paper) and something full of sense and meaning. Understanding of the text is determined by the reader’s inclusion into the world of social norms which is built upon the relay structures. The social relay (...) theory suggests the language for description and analysis of this world. (shrink)

The primary goal of the present research was to determine the order of swimmers on a mixed relay team that would ensure the best performance in the Fédération Internationale de Natation World Championships held in Kazan, Budapest, and Gwangju. The data were obtained from database websites for the 4 × 100 m freestyle and 4 × 100 m medley official results,1 including 660 records from 188 entries of finals and 472 preliminary events. The results showed that the fastest swimmers were (...) located primarily in the first or second positions of the freestyle relay. The most successful gender strategy for the 4 × 100 m freestyle and for the 4 × 100 m medley relays was the order male-male-female-female, although no statistical differences were found for the medley relays. In the 4 × 100 m freestyle, the second and third relay legs had a statistical effect on the total relay time, whereas in the 4 × 100 m medley, all four relay legs had a statistical effect on the final performance, the weight of the four strokes being different in heats with respect to the final round. Also, a later position of the first female swimmer or the consecutive position of two female swimmers in the team order significantly affected the relay performance in specific events. Mixed relay events appeared to present specific strategies in comparison to traditional male- or female-only relay lineups. (shrink)

In this work, we investigated a covert communication method in wireless networks, which is realized by multiantenna full-duplex single relay. In the first stage, the source node sends covert messages to the relay, and the relay uses a single antenna to send interference signals to the adversary node to protect the covert information being transmitted. In the second stage, the relay decodes and forwards the covert information received in the first stage; at the same time, the relay uses zero-forcing beamforming (...) to send interference signals to the warden to ensure covert transmission. The detection error rate, transmission outage probability, maximum effective covert rate, and other performance indicators are derived in two stages, and the total performance of the system is derived and analyzed. Then, the performance indicators are verified and analyzed by simulation. Our analysis shows that the maximum effective covert rate of using the characteristics of multiantenna to interfere with Willie in the second stage is taken as the total covert performance of the system, and the transmission interruption probability is significantly less than that of the first stage, so the corresponding maximum effective concealment efficiency will be greater.

The olfactory system was traditionally thought to lack a thalamic relay to mediate top-down influences from memory and attention in other perceptual modalities. Olfactory perception was therefore often described as an outlier among perceptual modalities. It was argued as a result that olfaction was a canonical example of a direct perception. In this paper we review functional and anatomical evidence which demonstrates that olfaction depends on both direct pathway connecting anterior piriform cortex to orbitofrontal cortex and an indirect thalamic circuit (...) connecting posterior piriform cortex and orbitofrontal cortices to the olfactory system. We argue that the indirect corticothalamic circuit has the structure to potentially mediate mediates top-down influences of memory and attention in olfactory perception. This suggests that olfaction is not an outlier after all. (shrink)

This paper is reporting on electronic implementation of a three-dimensional autonomous system with infinite equilibrium point belonging to a parabola. Performance analysis of an adaptive synchronization via relay coupling and a hybrid steganography chaos encryption application are provided. Besides striking parabolic equilibrium, the proposed three-dimensional autonomous system also exhibits hidden chaotic oscillations as well as hidden chaotic bursting oscillations. Electronic implementation of the hidden chaotic behaviors is done to confirm their physical existence. A good qualitative agreement is shown between numerical (...) simulations and OrCAD-PSpice results. Moreover, adaptive synchronization via relay coupling of three three-dimensional autonomous systems with a parabolic equilibrium is analysed by using time histories. Numerical results demonstrate that global synchronization is achieved between the three units. Finally, chaotic behavior found is exploited to provide a suitable text encryption scheme by hidden secret message inside an image using steganography and chaos encryption. (shrink)

Describing an algorithm can provide a formalization of a specific process. However, different ways of conceptualizing algorithms foreground certain issues while obscuring others. This article attempts to define an algorithm in a broad sense as a cultural activity of key importance to make sense of socio-cognitive structures. It also attempts to develop a sharper account on the interaction between humans and tools, symbols and technologies. Rather than human or machine-centered analyses, I draw upon sociological and anthropological theories that underline social (...) practices to propose expanding our understanding of an algorithm through the notion of ‘collective intentionalities’. To make this term clear, a brief historical review is presented, followed by an argumentation on how to incorporate it in an integral perspective. The article responds to recent debates in critical algorithm studies about the significance of the term. It develops a discussion along the lines of cognitive anthropology and the cognitive sciences, therefore advancing a definition that is grounded in observed practices as well as in modeled descriptions. The benefit of this approach is that it encourages scholars to explore cognitive structures via archaeologies of technological assemblages, where intentionalities play a defining role in understanding socio-structured practices and cognitive ecologies.

It has been customary to believe that apart from selection and abridgement Diodorus Siculus made little contribution to his Scholars have admitted the contribution of Diodorus himself when he refers to his native town Agyrium with some pride and to Sicily in general and when he occasionally records details of his own life. Beyond statements of this character, however, the tendency has been to assume that the origin of any particular statement is to be sought in the single source which (...) Diodorus was currently using, or, as others would argue, in the major source supplemented by a subsidiary source, or, as Tarn would postulate for 17, the medley of sources used by the Sicilian historian. An examination of the attribution of one item in 17 may throw some light on Diodorus as an historian. (shrink)
