Subject:
fuzzy coalition, probabilistic communication situation, average tree solution, and maximal product spanning tree
Language:
English
Description:
A probabilistic communication structure considers the setting with communication restrictions in which each pair of players has a probability to communicate directly. In this paper, we consider a more general framework, called a probabilistic communication structure with fuzzy coalition, that allows any player to have a participation degree to cooperate within a coalition. A maximal product spanning tree, indicating a way of the greatest possibility to communicate among the players, is introduced where the unique path from one player to another is optimal. We present a feasible procedure to find the maximal product spanning trees. Furthermore, for games under this model, a new solution concept in terms of the average tree solution is proposed and axiomatized by defining a restricted game in Choquet integral form.

Description:
We present here a bibliometric analysis of publications on photosynthesis research from 1992 to 2009 in the Science Citation Index Expanded (SCI-Expanded) Web of Science. This has allowed us to examine the growing trends and the key topics on this subject. We have assessed the document type, language of the publications, publication output, subject category, journal distribution, countries and territories of these publications, institutions involved, hot topics and highly cited papers. The top 30 countries/territories were ranked according to their total number of articles (TA), single country articles (SCA), internationally collaborative articles (ICA), first author articles (FAA) and corresponding author articles (CAA). Research directions on the subject of photosynthesis were also investigated and evaluated by statistically analyzing the distribution of author keywords in the database. Our analysis indicates that “water”, “stress”, “carbon dioxide”, “nitrogen” and “climate change” are hot topics of research on photosynthesis during this period., J. J. Yu ...

535. A binary operation-based representation of a lattice

Format:

Type:
model:article and TEXT
Subject:
binary operation, lattice, neutral element, and lattice representation
Language:
English
Description:
In this paper, we study and characterize some properties of a given binary operation on a lattice. More specifically, we show necessary and sufficient conditions under which a binary operation on a lattice coincides with its meet (resp. its join) operation. Importantly, we construct two new posets based on a given binary operation on a lattice and investigate some cases that these two posets have a lattice structure. Moreover, we provide some representations of a given lattice based on these new constructed lattices.

536. A biologically inspired neural model of vision-language integration

Subject:
Categorization, self-organization, visual cortex, and population coding
Language:
English
Description:
One crucial step in the construction of the human representation of the world is found at the boundary between two basic stimuli: visual experience and the sounds of language. In the developmental stage when the ability of recognizing objects consolidates, and that of segmenting streams of sounds into familiar chunks emerges, the mind gradually grasps the idea that utterances are related to the visible entities of the world. The model presented here is an attempt to reproduce this process, in its basic form, simulating the visual and auditory pathways, and a portion of the prefrontal cortex putatively responsible for more abstract representations of object classes. Simulations have been performed with the model, using a set of images of 100 real world objects seen from many different viewpoints and waveforms of labels of various classes of objects. Subsequently, categorization processes with and without language are also compared.

537. A blood pact: the significance and implications of eIF4E on lymphocytic leukemia

Subject:

Language:
English
Description:
Elevated levels of eukaryotic initiation factor 4E (eIF4E) are implicated in neoplasia, with cumulative evidence pointing to its role in the etiopathogenesis of hematological diseases. As a node of convergence for several oncogenic signaling pathways, eIF4E has attracted a great deal of interest from biologists and clinicians whose efforts have been targeting this translation factor and its biological circuits in the battle against leukemia. The role of eIF4E in myeloid leukemia has been ascertained and drugs targeting its functions have found their place in clinical trials. Little is known, however, about the pertinence of eIF4E to the biology of lymphocytic leukemia and a paucity of literature is available in this regard that prospectively evaluates the topic to guide practice in hematological cancer. A comprehensive analysis on the significance of eIF4E translation factor in the clinical picture of leukemia arises, therefore, as a compelling need. This review presents aspects of eIF4E involvement in the realm of the lymphoblastic leukemia status; translational control of immunological function via eIF4E and the state-of-the-art in drugs will also be outlined., V.

538. A Borel extension approach to weakly compact operators on $C_0(T)$.

Subject:
math and Borel extension theorem
Language:

Description:
Let $X$ be a quasicomplete locally convex Hausdorff space. Let $T$ be a locally compact Hausdorff space and let $C_0(T) = \lbrace f\: T \rightarrow I$, $f$ is continuous and vanishes at infinity$\rbrace $ be endowed with the supremum norm. Starting with the Borel extension theorem for $X$-valued $\sigma $-additive Baire measures on $T$, an alternative proof is given to obtain all the characterizations given in [13] for a continuous linear map $u\: C_0(T) \rightarrow X$ to be weakly compact.

539. A bound for the rank-one transient of inhomogeneous matrix products in special case

Language:

Description:
We consider inhomogeneous matrix products over max-plus algebra, where the matrices in the product satisfy certain assumptions under which the matrix products of sufficient length are rank-one, as it was shown in [6] (Shue, Anderson, Dey 1998). We establish a bound on the transient after which any product of matrices whose length exceeds that bound becomes rank-one.

540. A bound on the $k$-domination number of a graph

Subject:
domination, $k$-domination number, and $P_4$-free graphs
Language:
English
Description:
Let $G$ be a graph with vertex set $V(G)$, and let $k\ge 1$ be an integer. A subset $D \subseteq V(G)$ is called a {\it $k$-dominating set} if every vertex $v\in V(G)-D$ has at least $k$ neighbors in $D$. The $k$-domination number $\gamma _k(G)$ of $G$ is the minimum cardinality of a $k$-dominating set in $G$. If $G$ is a graph with minimum degree $\delta (G)\ge k+1$, then we prove that $$\gamma _{k+1}(G)\le \frac {|V(G)|+\gamma _k(G)}2.$$ In addition, we present a characterization of a special class of graphs attaining equality in this inequality.
