Efficient Skyline Querying with Variable User Preferences on Nominal Attributes

, 2007
Current skyline evaluation techniques assume a fixed ordering on the attributes. However, dynamic preferences on nominal attributes are more realistic in known applications.

Parameterized complexity of the MINCCA problem on graphs of bounded decomposability

, 2016
In an edge-colored graph, the cost incurred at a vertex on a path when two incident edges with different colors are traversed is called reload or changeover cost.

Gruenhage compacta and strictly convex dual norms

, 2007
We prove that if K is a Gruenhage compact space then C(K)* admits an equivalent, strictly convex dual norm. As a corollary, we show that if X is a Banach space and X* is the |.|-closed linear span of K, where K is a Gruenhage compact in the w*-topology ...

Guarded Second-Order Logic, Spanning Trees, and Network Flows

, 2010
According to a theorem of Courcelle monadic second-order logic and guarded second-order logic (where one can also quantify over sets of edges) have the same expressive power over the class of all countable $k$-sparse hypergraphs. In the first part of the

Dynamic Interference Mitigation for Generalized Partially Connected Quasi-static MIMO Interference Channel

, 2011
Recent works on MIMO interference channels have shown that interference alignment can significantly increase the achievable degrees of freedom (DoF) of the network. However, most of these works have assumed a fully connected interference graph.

Species-specific difference of CO₂ emissions in mangroves: coupling sediment physicochemistry and microbial communities

Frontiers in Microbiology
Mangrove ecosystems function simultaneously as carbon sinks and carbon sources. While their contribution to biomass accumulation and long-term carbon sequestration have been extensively studied, the mechanisms driving carbon emissions, particularly those

Kernel Supervised Ensemble Classifier for the Classification of Hyperspectral Data Using Few Labeled Samples

Remote Sensing, 2016
Kernel-based methods and ensemble learning are two important paradigms for the classification of hyperspectral remote sensing images. However, they were developed in parallel with different principles.
