A Game-Theoretic Framework for Medium Access Control [PDF]

, 2008
In this paper, we generalize the random access game model, and show that it provides a general game-theoretic framework for designing contention based medium access control.

On the uniqueness of extension and unique best approximation in the dual of an asymmetric normed linear space

Journal of Numerical Analysis and Approximation Theory, 2003
A well known result of R. R. Phelps (1960) asserts that in order that every linear continuous functional, defined on a subspace \(Y\) of a real normed space \(X\), have a unique norm preserving extension it is necessary and sufficient that its ...

Uniqueness of Best Approximation with Coefficient Constraints

Rocky Mountain Journal of Mathematics, 1993
Let for given \(\alpha= (\alpha_ 1,\dots, \alpha_ n)\) and \(\beta= (\beta_ 1,\dots, \beta_ n)\), with \(-\infty\leq \alpha_ i< \beta_ i\leq\infty\), \(i=1,\dots, n\), and continuous functions \(u_ 1,\dots,u_ n\), set \(U(\alpha,\beta)= \{\sum_{i=1}^ n a_ i U_ i\); \(\alpha_ i\leq a_ i\leq\beta_ i\), \(i=1,\dots, n\}\). In this paper the conditions for

CHARACTERIZATIONS AND UNIQUENESS OF BEST SIMULTANEOUS $\tau_C$-APPROXIMATIONS

Taiwanese Journal of Mathematics, 2011
This paper is concerned with the problem of best simultaneous $\tau_C$-approximations in terms of the Minkowski functional. The notions of simultaneous sun and simultaneous regular set are extended to suit the case of simultaneous $\tau_C$-approximation problems. Characterization and uniqueness results are established for simultaneous $\tau_C$-suns.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The Networked Common Goods Game

, 2010
We introduce a new class of games called the networked common goods game (NCGG), which generalizes the well-known common goods game. We focus on a fairly general subclass of the game where each agent's utility functions are the same across all goods the ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Uniqueness of best approximation by monotone polynomials

Journal of Approximation Theory, 1971
The purpose of this paper is twofold. First, we prove the uniqueness of a polynomial of best uniform approximation, in a certain class P of “monotone” polynomials, to a given continuous function. This is the content of Theorem 3.1 which complements the results of Lorentz and Zeller [l].

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

From Nonlinear Identification to Linear Parameter Varying Models: Benchmark Examples

, 2018
Linear parameter-varying (LPV) models form a powerful model class to analyze and control a (nonlinear) system of interest. Identifying a LPV model of a nonlinear system can be challenging due to the difficulty of selecting the scheduling variable(s) a ...
