Calcium Sparks

Physiological Reviews, 2008
The calcium ion (Ca2+) is the simplest and most versatile intracellular messenger known. The discovery of Ca2+sparks and a related family of elementary Ca2+signaling events has revealed fundamental principles of the Ca2+signaling system. A newly appreciated “digital” subsystem consisting of brief, high Ca2+concentration over short distances (nanometers

Finding the Spark

Bioelectricity, 2021
It began, as with many good things, at a happy hour. Adam Cohen, a young assistant professor asked whether rhodopsins could be used to optically sense voltage. In the heady days of 2009, channel rhodopsin had just been unveiled as a voltage actuator in neurons.

Easy Spark. [PDF]

open access: possible, 2021
Today's data deluge calls for novel, scalable data handling and processing solutions. Spark has emerged as a popular distributed in-memory computing engine for processing and analysing a large amount of data in parallel. However, the way parallel processing pipelines are designed is fundamentally different from traditional programming techniques, and ...

Spark SQL

Proceedings of the 2015 ACM SIGMOD International Conference on Management of Data, 2015
Spark SQL is a new module in Apache Spark that integrates relational processing with Spark's functional programming API. Built on our experience with Shark, Spark SQL lets Spark programmers leverage the benefits of relational processing (e.g. declarative queries and optimized storage), and lets SQL users call complex analytics libraries in Spark (e.g ...

LOCATION OF THE POSITION OF A SPARK IN A SPARK CHAMBER

Nuclear Instruments and Methods, 1962
Abstract With special electrodes having the structure of a distributed delay-line, it is shown, by measuring the delay between the arrival of the signals following a spark at two opposite ends of the electrodes, that the initial position of the spark can be determined.
