Ad-hoc contracting allows to quickly react changes which could be neglected or noticed too late in case of constant contracting. But always deciding anew, e.g., how much and what order commercial buy private life, is cumbersome. To capture the cognitive burden ad-hoc it can avoided by contracting, our setup confronts pricing, non-revealing, with constantly revealing pricing. The experiment modi...

In many systems, sensors are used to acquire information from external environments such as temperature, pressure and locations. Due to continuous changes in these values, and limited resources (e.g., network bandwidth and battery power), it is often infeasible for the database to store the exact values at all times. Queries that uses these old values can produce invalid results. In order to ma...

This paper introduces a new approach for efficiently indexing and querying constantly evolving data. Traditional data index structures suffer from frequent updating cost and result in unsatisfactory performance when data changes constantly. Existing approaches try to reduce index updating cost by using a simple linear or recursive function to define the data evolution, however, in many applicat...

Elucidating the origin of and dynamic interrelationship between intratumoral cell subpopulations has clear clinical significance in helping to understand the cellular basis of treatment response, therapeutic resistance, and tumor relapse. Cancer stem cells (CSC), together with clonal evolution driven by genetic alterations, generate cancer cell heterogeneity commonly observed in clinical sample...
