Wnt signaling in cardiovascular disease: opportunities and challenges [PDF]
Current Opinion in Lipidology, 2017 Purpose of reviewCardiometabolic diseases increasingly afflict our aging, dysmetabolic population. Complex signals regulating low-density lipoprotein receptor-related protein (LRP) and frizzled protein family members – the plasma membrane receptors for the cadre of Wnt polypeptide morphogens – contribute to the control of cardiovascular homeostasis ...

A Model of Smiling as a Costly Signal of Cooperation Opportunities [PDF]
Adaptive Human Behavior and Physiology, 2015 We develop a theoretical model under which “genuine” or “convincing” smiling is a costly signal that has evolved to induce cooperation in situations requiring mutual trust. Prior to a trust interaction involving a decision by a sender to send money to a recipient, the recipient can emit a signal to induce the sender to trust them.

The new algorithm of sinusoidal signal frequency estimation
, 2013 In this paper we consider the new estimation algorithm of the measured sinusoidal signal frequency. Unlike most of known similar methods, the proposed algorithm provides the opportunity of partial rejection of unaccounted disturbances presenting in the ...
