Planarians can regenerate any missing body part, requiring mechanisms for the production of organ systems in the adult, including their prominent tubule-based filtration excretory system called protonephridia. Here, we identify a set of genes, Six1/2-2, POU2/3, hunchback, Eya and Sall, that encode transcription regulatory proteins that are required for planarian protonephridia regeneration. Dur...

The Spalt-like family of zinc finger transcription factors is conserved throughout evolution and is involved in fundamental processes during development and during embryonic stem cell maintenance. Although human SALL1 is modified by SUMO-1 in vitro, it is not known whether this post-translational modification plays a role in regulating the activity of this family of transcription factors. Here,...

We describe ongoing research towards building a cognitively plausible system for near one-shot learning of the meanings of attribute words and object names, by grounding them in a sensory model. The system learns incrementally from human demonstrations recorded with the Microsoft Kinect, in which the demonstrator can use unrestricted natural language descriptions. We achieve near-one shot learn...

A wave glider can convert vertical motion into its forward propulsion. There are many factors affecting the propulsion performance of a glider. The swing amplitude hydrofoil affect efficiency to capture energy, and pull direction an umbilical cable transmission energy. In this paper, optimized mechanism with self-adjusting lower limit (SALL) was proposed by analyzing un- synchronized movement b...

There are errors in the Funding section that were not corrected during the typesetting process. The correct funding information is as follows: This work was supported by the Sall Family Foundation via the Pan American Health and Education Foundation (renamed PAHO Foundation) and EUROHEALTH. The funders had no role in study design, data collection and analysis, decision to publish, or preparatio...
