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

SParking

Adjunct Proceedings of the 2020 ACM International Joint Conference on Pervasive and Ubiquitous Computing and Proceedings of the 2020 ACM International Symposium on Wearable Computers, 2020
With a rapid growth of vehicles in modern cities, searching for a parking space becomes difficult for drivers especially in rush hours. To alleviate parking difficulties and make the most of urban parking resources, contract parking sharing services allow drivers to pay for parking under the consent of owners, reaching a win-win situation.

Assessment of ultra-lean burn characteristics for a stratified-charge direct-injection spark-ignition methanol engine under different high compression ratios

, 2020
Lean burn is one of the most important characteristics of a stratified-charge direct-injection spark-ignition engine. In this study, a non-uniform 10-hole × 0.30 mm spray-line distribution nozzle was chosen to achieve stratified-charge of the methanol ...
