To investigate the in-situ response to a stress, grapevine leaves have been subjected to mass spectrometry imaging (MSI) experiments. The Matrix Assisted Laser Desorption/Ionisation (MALDI) approach using different matrices has been evaluated. Among all the tested matrices, the 2,5-dihydroxybenzoic acid (DHB) was found to be the most efficient matrix allowing a broader range of detected stilben...

In a Voronoi game, each of κ ≥ 2 players chooses a vertex in a graph G = 〈V(G),E(G)〉. Theutility of a player measures her Voronoi cell: the set of vertices that are closest to her chosenvertex than to that of another player; each vertex contributes uniformly to the utilities of playerswhose Voronoi cells the vertex belongs to. In a Nash equilibrium, unilateral deviation of a player<...

Previous work has found that (a) when software is developed collaboratively, concurrent accesses to related pieces of code are made, and (b) when these accesses are coordinated asynchronously through a version control system, they result in increased defects because of conflicting concurrent changes. Previous findings also show that distance collaboration aggravates software-development problem...

A significant gap exists in early-stage seed capital for technology-based new ventures. This article reports the results of a survey of embryonic firms in the southwestern United States, which received significant amounts of their initial capital from strategic partners. Our concern in this paper is the resource development process of high-growth (technology-intensive), early-stage firms throug...

Augmented reality (AR) allows users to see the real world, with virtual objects superimposed on the real world. AR systems can be used to establish the experience of being practically co-located by means of simulated presence. AR systems have, e.g., been used to allow experts to spatially collaborate with others at any other place in the world without traveling and thereby creating the experien...

Since market and environmental conditions are becoming increasingly turbulent, ICT sourcing alternatives (such as colocation) have gained considerable attention in the industry since they allow firms to become more agile and responsive to environmental changes and increasing competition. However, little research has been conducted to analyze how different factors affect ICT sourcing decisions i...

This paper explores the role of transactive memory in enabling knowledge transfer between globally distributed teams. While the information systems literature has recently acknowledged the role transactive memory plays in improving knowledge processes and performance in colocated teams, little is known about its contribution to distributed teams. To contribute to filling this gap, knowledge-tra...

We present a concept for tangible visualization views using colocated, spatially-aware mobile devices. The proposed concept takes advantage of ad-hoc device combinations and spatial arrangements, allowing users to interact with multiple coordinated visualization views distributed across mobile displays. In this work, we describe the basics of this concept and illustrate the potential of our app...

A co-location pattern is a group of spatial features/events that are frequently co-located in the same region. For example, human cases of West Nile Virus often occur in regions with poor mosquito control and the presence of birds. For colocation pattern mining, previous studies often emphasize the equal participation of every spatial feature. As a result, interesting patterns involving events ...
