Inferring genetic interactions from comparative fitness data

open access: yeseLife, 2017
Darwinian fitness is a central concept in evolutionary biology. In practice, however, it is hardly possible to measure fitness for all genotypes in a natural population.

Relational Theory of Risk and Its Applications to Game Theory Problems of Non-Numerical Economics

open access: yesСтатистика и экономика, 2021
The purpose of the work is to study the foundations of a general risk theory. To form a single formal concept of risk, a number of definitions of the term “risk” found in the literature have been analyzed.

Fixed points of α-Θ-Geraghty type and Θ-Geraghty graphic type contractions

open access: yesApplied General Topology, 2017
In this paper, by using the concept of the α-Garaghty contraction, we introduce the new notion of the α-Θ-Garaghty type contraction and prove some fixed point results for this contraction in partial metric spaces.

Partial Order Ranking of the Key Drivers of Grassland Conversion in the Urban–Grassland Interface: A Case Study of the Hohhot–Baotou–Ordos Region

open access: yesApplied Sciences
Identifying and ranking the key drivers of grassland conversion at the county level is crucial for developing targeted policies and improving protection efficiency.

Forward-chaining partial-order planning

open access: yes, 2010
Over the last few years there has been a revival of interest in the idea of least-commitment planning with a number of researchers returning to the partial-order planning approaches of UCPOP and VHPOP.

Stochastic Partial Ordering

open access: yesThe Annals of Probability, 1978
A probability measure $P$ on a partially ordered Polish space $E$ is called stochastically smaller than $Q$ (notation: $P \leqslant Q$) if $\int f dP \leqslant \int f dQ$ holds for all bounded increasing measurable $f$. We investigate the question when for a stochastically increasing family $\{P_t, t \in \mathbb{R}\}$ there exists an increasing process

Separation axioms for partially ordered convergence spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
In partially ordered convergence spaces, separation axioms are introduced and then related to the concept of complete separatedness due to Nachbin as well as to connectedness concepts. A method to generate new separation axioms is studied.

Non-Determinism and Nash Equilibria for Sequential Game over Partial Order [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
In sequential games of traditional game theory, backward induction guarantees existence of Nash equilibrium by yielding a sub-game perfect equilibrium.

Ramsey numbers of partial order graphs (comparability graphs) and implications in ring theory

open access: yesOpen Mathematics, 2020
For a partially ordered set (A,≤)(A,\le ), let GA{G}_{A} be the simple, undirected graph with vertex set A such that two vertices a≠b∈Aa\ne b\in A are adjacent if either a≤ba\le b or b≤ab\le a.

Low Complexity Method for Channel-Dependent Construction of Polar Codes Using Partial Order

open access: yesIEEE Access, 2018
In this paper, a novel low-complexity method for channel-dependent construction of polar codes is designed by exploiting the partial order (PO) relation to eliminate redundant computations. The proposed method selects the information set with a threshold,
