Optimality testing in stochastic and heuristic algorithms

Technological and Economic Development of Economy, 2006
In this paper we consider the application of order statistics to establish the optimality in stochastic and heuristic optimization algorithms. We suggest a method for the estimation of confidence intervals of minimum using order statistics which is ...

NKCC1: A key regulator of glioblastoma progression

Molecular Oncology, EarlyView.
Glioblastoma (GBM) progression is driven by disrupted chloride cotransporter homeostasis. NKCC1 is highly expressed in stem‐like, astrocytic, and progenitor cells, correlating with earlier recurrence, while overall survival remains unaffected. NKCC1 serves as a prognostic marker and potential therapeutic target, linking chloride transporter imbalance ...

DNA methylation and expression of MAPRE3 affect overall survival of early‐stage non‐small cell lung cancer patients

Molecular Oncology, EarlyView.
Both cg12821679MAPRE3 methylation and MAPRE3 expression are significantly associated with overall survival (OS) of non‐small cell lung cancer. Meanwhile, MAPRE3 expression significantly modified the effect of smoking cessation on OS. Smoking cessation benefits OS merely for patients with high MAPRE3 expression.

Image Stego Detection using Higher Order Statistics

مجلة النهرين للعلوم الهندسية, 2010
The basic approach taken here works by finding predictable higher-order statistics of natural images within a multi-scale decomposition, and then showing that embedded messages alter these statistics. A Fisher linear discriminant analysis is then used

Survival probability and order statistics of diffusion on disordered media

, 2002
We investigate the first passage time t_{j,N} to a given chemical or Euclidean distance of the first j of a set of N>>1 independent random walkers all initially placed on a site of a disordered medium.

Teletraffic Analysis of OFDMA Cellular Systems With Persistent VoIP Users and Maximum SIR Scheduling Based on Order Statistics

IEEE Access, 2018
Voice over IP (VoIP) is the multimedia service with the fastest growth on current cellular systems and this trend will continue in the future. Voice transmission by VoIP users with traditional dynamic scheduling schemes could become a bottleneck in the ...

On Arnold–Villasenor Conjectures for ˜ Characterizing Exponential Distribution Based on Sample of Size Three

Revstat Statistical Journal, 2020
Arnold and Villase˜nor [4] obtain a series of characterizations of the exponential distribution based on random samples of size two. These results were already applied in constructing goodness-of-fit tests in [7].

Recombining dependent data: an Order Statistics [PDF]

This article discusses the problem of forming groups from previously split data. Algorithms for Cluster Analysis like SAR proposed by Peña, Rodriguez and Tiao (2004), divide the sample into small very homogeneous groups and then recombine them to form ...
