Courtship in long-legged flies (Diptera: Dolichopodidae): function and evolution of signals

M. Zimmer
2003 Behavioral Ecology  
Analyzing the courtship behavior of long-legged flies (Diptera: Dolichopodidae), we focus on the evolutionary development of courtship signals.  ...  Long-legged flies may serve as a model for this evolutionary process, because males of some species present sexually dimorphic badges during courtship, whereas others do not exhibit such conspicuous signals  ...  Comparing the visual information of both positions may reveal distance information.  ...

Human Factors Considerations for Enabling Functional Use of Exosystems in Operational Environments

Leia Stirling, Ho Chit Siu, Eric Jones, Kevin Duda
2018 IEEE Systems Journal  
We present examples of these concepts in the context of exosystem design for operational environments and to aid the development of system evaluation standards.  ...  We also review current exosystem evaluation methods and present how performance metrics and tasks can be expanded to better describe system function in the context of known human factors complexities.  ...  ACKNOWLEDGMENT The authors would like to thank Ms. T. Sun for her help in categorizing the literature review papers and Prof. N. Leveson for her comments during the preparation of this manuscript.  ...

Head and Tibial Acceleration as a Function of Stride Frequency and Visual Feedback during Running

Michael A. Busa, Jongil Lim, Richard E. A. van Emmerik, Joseph Hamill, Mani Alikhani
2016 PLoS ONE  
Furthermore, impact accelerations of the head and tibia appear to be solely a function of stride frequency as no differences were observed between feedback conditions.  ...  Decreasing stride frequency resulted in greater vertical accelerations of the tibia (p<0.01) during early stance and at the head (p<0.01) during early and late stance; however, for the impact portion the  ...  Statistical Analysis The effects of stride frequency and visual task on tibial and head accelerations, transfer function, and head gaze point dynamics were evaluated with a series of linear mixed model  ...

2013 PLoS ONE  
We investigate the relationship between characteristics of dog breeds and their popularity between years 1926 and 2005.  ...  Our results support the hypothesis that dog breed popularity has been primarily determined by fashion rather than function.  ...  Acknowledgments We thank the American Kennel Club for providing breed registration data.

Yusuf Osmanlıoğlu, Birkan Tunç, Drew Parker, Mark A. Elliott, Graham L. Baum, Rastko Ciric, Theodore D. Satterthwaite, Raquel E. Gur, Ruben C. Gur, Ragini Verma
2019 NeuroImage  
The brain can be considered as an information processing network, where complex behavior manifests as a result of communication between large-scale functional systems such as visual and default mode networks  ...  Notably, matching between structural and functional connectivity for the functionally specialized modular systems such as visual and motor networks are higher as compared to other more integrated systems  ...  We would like to thank the anonymous reviewers for their valuable suggestions which greatly improved the content and the presentation of this manuscript.  ...
