The family Cerophytidae is revised to include Afrocerophytum vix gen. nov. and sp. nov., from the tropical rainforest of western Africa. Afrocerophytum and A. vix (type locality: Ivory Coast, Tai Region, neighborhood of Gouleako village) are described and illustrated. A key to the Cerophytidae genera is provided. The new genus is distinguished by four autapomorphies: anterior edge of phallobase...

Markov Random Fields (MRFs) are proposed as viable stochastic models for the spatial distribution of gray levels for images of human faces. These models are trained using data bases of face and non-face images. The trained MRF models are then used for detecting human faces in test images. We investigate the performance of the face detection algorithm for two classes of MRFs given by the firstan...

A new iterative and interactive algorithm called CSN (Classification by Successive Neighborhood) to be used in a complex descriptive objects identification approach is presented. Complex objects are those designed by experts within a knowledge base to describe taxa (monography species) and also real organisms (collection specimens). The algorithm consists of neighborhoods computations from an i...

This paper describes the system submitted to the TAC 2013 entity linking task of the Knowledge Base Population track. The core of the approach is probabilistic information retrieval over a search index of the knowledge base, including the text of Wikipedia. The retrieval results are further reranked using a supervised learning-to-rank model. The submission this year builds on the neighborhood a...

In this paper, we propose two mechanisms for wormhole detection in wireless sensor networks. The proposed mechanisms are based on hypothesis testing and they provide probabilistic results. The first mechanism, called the Neighbor Number Test (NNT), detects the increase in the number of the neighbors of the sensors, which is due to the new links created by the wormhole in the network. The second...

It is generally accepted that a rational belief must be grounded in the evidence available to an agent. However, there is much less agreement about the precise relationship between an agent’s beliefs and her evidence. Understanding this complex mechanism raises many interesting philosophical and technical issues. Modeling evidence requires richer structures than found in standard epistemic sema...

mixed land use includes various land uses which are adjacent to each other and linked together to accommodate either horizontal or vertical segments adjacent land and within a building to coexistence. recent urban planning theories, emphasizing on several principles that make the mix use development is one of these principles. mixed land use effects on travel demands and urban transportation ef...

The designation of which resources are valued as emerging heritage is at a turning point. This has resulted in urban regeneration processes designed from the top down, neglecting perception local. article highlights importance generating participatory multi-actor spaces where knowledge agents involved same process regeneration, this case linked to obsolete neighborhoods, can be incorporated and...

Let D be a simple digraph without loops or digons. For any v ∈ V (D), the first out-neighborhood N(v) is the set of all vertices with out-distance 1 from v and the second neighborhood N(v) of v is the set of all vertices with out-distance 2 from v. We show that every simple digraph without loops or digons contains a vertex v such that |N++(v)| ≥ γ|N+(v)|, where γ = 0.657298 . . . is the unique ...
