REaltime ACtive Heterogeneous Systems - Where Did We Reach After REACH? [chapter]

Thomas Kudraß
2010 Lecture Notes in Computer Science  
This paper gives a survey of the deployment of ideas from the area of real-time, active and heterogeneous database systems in the years from 1991 to 2010 as they have been embraced by IT industry.  ...  After 20 years it is time to conclude insights how far the ideas of the first project REACH are still valid for the development of commercial products and standards.  ...  In many cases, the REACH ideas were a key to understand conceptual and architectural issues of system design.  ...

On Failing to Reach Escape Velocity Beyond Modernity

Fernando Elichirigoity
2000 Social Studies of Science  
A history of essences, the modern project, needs to give way to a history of contingent processes and assemblages.  ...  He also wants to preserve what he calls the "essence" of technology, and yet also argue that technology is historically contingent. We cannot have both at the same time.  ...  This can be the real grounding of democratic activity because it can make constant reference to the emergence, in real time, of assemblages of people and machines that have been oriented towards the development  ...

HD-tDCS over mIPS causally modulates online reach correction [article]

Alexander Goettker, Brandon Caie, Jerrold Jeyachandra, Sisi Xu, Jason Gallivan, Jacek Dmochowski, Katja Fiehler, Gunnar Blohm
2019 bioRxiv   pre-print
Importantly, using a mediation analysis of the relationship between stimulation current and movement curvature, we provide causal evidence that the induced current modifies brain activity, which then leads  ...  This unique combination of methods and analysis thus provides complementary evidence for the crucial role of the posterior parietal cortex in online error correction, while at the same time setting a new  ...  possible with real or virtual lesions who simply disrupt the activity.  ...

Forward modeling allows feedback control for fast reaching movements

Michel Desmurget, Scott Grafton
2000 Trends in Cognitive Sciences  
In such a model, the probable position and velocity of an effector can be estimated with negligible delays and even predicted in advance, thus making feedback strategies possible for fast reaching movements  ...  The parietal lobe and cerebellum appear to play a crucial role in this process.  ...  Acknowledgements We thank Helene Gréa, Dr Claude Prablanc and Dr Denis Pélisson for their helpful remarks and their critical reading of this manuscript.  ...

A comparison of techniques for multi-display reaching

Miguel A. Nacenta, Dzmitry Aliakseyeu, Sriram Subramanian, Carl Gutwin
2005 Proceedings of the SIGCHI conference on Human factors in computing systems - CHI '05  
We found that techniques like the Radar View and Pick-and-Drop, that have a control-to-display ratio of 1, are significantly faster for object movement than techniques that have smaller control-to-display  ...  We conducted a study to compare the efficiency of six techniques for moving objects from a tablet to a tabletop display.  ...  We thank the reviewers for insightful comments and suggestions.  ...

Time course of cellular and molecular regulation in the immune system in altered gravity: Progressive damage or adaptation ?

Cora S. Thiel, Beatrice A. Lauber, Jennifer Polzer, Oliver Ullrich
2017 REACH  
Therefore, we assume that the human body and its cells are equipped with a robust and efficient adaptation potential when challenged with low gravitational environments. a b s t r a c t We summarized the  ...  Many studies indicate an adaptation reaction of the immune system to the new microgravity environment, at least for the T cell system.  ...  T cell signaling was mostly studied in cell culture systems in real and simulated microgravity in short time frames until 3 days.  ...

Immediate and delayed reaching in hemispatial neglect

Stéphanie Rossit, Keith Muir, Ian Reeves, George Duncan, Philip Birschel, Monika Harvey

Parallel basal ganglia circuits for voluntary and automatic behaviour to reach rewards

Hyoung F. Kim, Okihide Hikosaka
2015 Brain  
A notable example is the circuits that originate from the rostral (head) and caudal (tail) regions of the caudate nucleus, both of which target the superior colliculus.  ...  Moreover, separate groups of dopamine neurons innervate the caudate head and tail and may selectively guide the flexible and stable learning/memory in the caudate regions.  ...  However, the strict dichotomy of memory into short-term versus long-term systems may not be correct. The time course of memory might vary in a graded manner.  ...

Cancer stem cells - from initiation to elimination, how far have we reached? (Review)

2009 International Journal of Oncology  
Cancer stem cells (CSCs) are rare tumor cells that have the potential to proliferate, self-renew and induce tumorigenesis.  ...  Over the past few years, CSCs have been isolated from several different tumors and when implanted into immune-deficient mice, generate tumors that are identical to the parental tumors.  ...  Acknowledgements We thank Drs Tracy Adair-Kirk, Robert Delsite and Feng Zhihui for helpful suggestions and comments during the preparation of this manuscript.  ...
