U -Statistics

Aad van der Vaart • Cambridge University Press eBooks (1998)

One-sample U -statistics can be regarded as generalizations of means. They are sums of dependent variables, but we show them to be asymptotically normal by the projection method. Certain interesting test statistics, such as the Wilcoxon sta...

Constraining PERMANOVA and LDM to within-set comparisons by projection improves the efficiency of analyses of matched sets of microbiome data

Zhengyi Zhu, Glen A. Satten, Caroline Mitchell, Yi-Juan Hu • Microbiome (2021)

Abstract Background Matched-set data arise frequently in microbiome studies. For example, we may collect pre- and post-treatment samples from a set of individuals, or use important confounding variables to match data from case participants ...

Six‐face cubical key encryption and decryption based on product cipher using hybridisation and Rubik's cubes

Rajavel Dhandabani, Shantharajah S. Periyasamy, Padma Theagarajan, Arun Kumar Sangaiah • IET Networks (2018)

This paper deals with the novel approach to generate cubical key that symbolises the message and key in six‐face cubical structure. The cubical message is hybridised to generate the cipher in the encryption. Hybridisation of cubes is perfor...

R-Local Unlabeled Sensing: A Novel Graph Matching Approach for Multiview Unlabeled Sensing Under Local Permutations

Ahmed Abbasi, Abiy Tasissa, Shuchin Aeron • IEEE Open Journal of Signal Processing (2021)

Unlabeled sensing is a linear inverse problem where the measurements are scrambled under an unknown permutation leading to loss of correspondence between the measurements and the rows of the sensing matrix. Motivated by practical tasks such...

Context presentation and native conversation structure in large language model responses to escalating suicide risk: a controlled multimodel evaluation

Jueqiao Liu, Jueqiao Liu, Xiaoyi Chen, Jun Cai et al. • Frontiers in Psychiatry (2026)

BackgroundLarge language models are increasingly used for informal mental health support, yet their safety during escalating suicide-risk conversations may depend on how prior information is presented. Native multi-turn conversations and re...

EPEPT: A web service for enhanced P-value estimation in permutation tests

Knijnenburg Theo A, Lin Jake, Rovira Hector, Boyle John et al. • BMC Bioinformatics (2011)

Abstract Background In computational biology, permutation tests have become a widely used tool to assess the statistical significance of an event under investigation. However, the common way of computing the P-value, which expresses the sta...

The KLT relation from the tree formula and permutohedron

Qu Cao, Liang Zhang • European Physical Journal C: Particles and Fields (2023)

Abstract In this paper, we generalize the Nguyen–Spradlin–Volovich–Wen (NSVW) tree formula from the MHV sector to any helicity sector. We find a close connection between the Permutohedron and the KLT relation, and construct a non-trivial ma...

Quantum Computing

José Luis Hevia, Guido Peterssen, Christof Ebert, Mario G. Piattini • IEEE Software (2021)

Have you ever tried to retrieve that forgotten key code for your suitcase? After one year without traveling, many of us found themselves having forgotten the combination and manually trying all permutations. The same situation, but more com...

Strengths and Weaknesses of Quantum Computing

Charles H. Bennett, Ethan Bernstein, Gilles Brassard, Umesh V. Vazirani • SIAM Journal on Computing (1997)

Recently a great deal of attention has been focused on quantum computation following a sequence of results [Bernstein and Vazirani, in Proc. 25th Annual ACM Symposium Theory Comput., 1993, pp. 11--20, SIAM J. Comput., 26 (1997), pp. 1277--1...

Diminished Auditory Responses during NREM Sleep Correlate with the Hierarchy of Language Processing.

Meytal Wilf, Michal Ramot, Edna Furman-Haran, Anat Arzi et al. • PLoS ONE (2016)

Natural sleep provides a powerful model system for studying the neuronal correlates of awareness and state changes in the human brain. To quantitatively map the nature of sleep-induced modulations in sensory responses we presented participa...

Data-driven performance prediction of polymer solar cells using multi-layer perceptron with Bayesian hyperparameter tuning

Sun Ping • Materials Research Express (2026)

Polymer solar cells (PSCs) rely on labor-intensive trial-and-error experiments to optimize power conversion efficiency (PCE), due to complex coupling of molecular electronic properties, blend morphology and fabrication parameters. This work...

Benchmarking Supervised Classifiers for Concurrent Multidomain Dropout-Intention Attributions in Higher Education: Evidence from a Colombian Public University

Marieth Agnes Guillen-García, Osnamir Elias Bru-Cordero, Cristian David Correa-Álvarez • Big Data and Cognitive Computing (2026)

Student retention analytics often treats withdrawal as a single outcome, although students may attribute dropout intention to personal, socioeconomic, and academic pressures simultaneously. We benchmarked nine supervised classifiers for ide...
