Advances in Switched-Mode Power Conversion Part I

Slobodan Cuk, R. D. Middlebrook
1983 IEEE transactions on industrial electronics (1982. Print)  
A new concept in the design of switched-mode power conversion circuitry is presented.  ...  A thorough discussion of the background, development, and operation of the Cuk converter and several of its extensions is included.  ...  This is quite unlike the conventional push-pull class B linear amplifiers for which a push-pull configuration would be a more appropriate designation.  ...

Matrilineal motives: kinship, witchcraft, and repatriation among Congolese refugees

ANDREW APTER
2012 Journal of the Royal Anthropological Institute  
As with Bourdieu's structuring structures, the regenerative scheme incorporates prior transformations within its reproductive logic, bringing the history of pawnship and slavery into gendered conversions  ...  But in nearly all cases, the push factors were negative, framed by witchcraft idioms of stolen blood and body parts within a zero-sum calculus of losses and gains.  ...

The rise of the starlet sea anemone Nematostella vectensis as a model system to investigate development and regeneration

Michael J. Layden, Fabian Rentzsch, Eric Röttinger
2016 Wiley Interdisciplinary Reviews: Developmental Biology  
However, Nematostella is now going beyond its intended utility with potential as a model to better understand other areas such as regenerative biology, EcoDevo, or stress response.  ...  Lastly, the sum of research to date in Nematostella has generated a variety of tools that aided the rise of Nematostella to a viable model system.  ...  When the tentacle buds become visible, (2) the mesenteries are pulled/pushed down to create a gap between the amputation site and the mesenteries where high proliferation is detected and where (3) the  ...

Settler Colonial Socialization in Public Sector Work: Moving from Privilege to Complicity

Nisha Nath, Willow Samara Allen
2022 Studies in Social Justice  
In this piece, we ask, what are the risks of a pedagogy and politics that begins and ends with privilege?  ...  We argue that declarations of privilege risk reproducing settler-centric logics that maintain settler colonialism, settler jurisdiction, and settler certainty, and we reflect on how to orient participants  ...  Acknowledgements We wish to acknowledge the participants who committed to being "in the deep" of the research process with us, during a global pandemic no less.  ...

Controls of Hair Follicle Cycling

K. S. Stenn, R. Paus
2001 Physiological Reviews  
Two possible forces are envisioned, a push or a pull (449) . It is notable that direct evidence for either the push or pull theories has not been offered.  ...  Because the Notch receptor is abundantly expressed on differentiating cells, it is thought to play a role in establishing or maintaining a differentiated state, but how it effects this event is not yet  ...

2017 Digital Humanities Conference  
SethBling's hack then produces a chimeric object; a hybrid of plastic, logic, and time; the ghost of one game haunting the shell of another.  ...  This haunting constitutes, as this short paper argues, a regenerative practice: a "circuit bending," to draw on a theoretical and practical challenge from Garnet Hertz and Jussi Parikka, that engages the  ...
