Permutation Statistics of Indexed Permutations

open access: yesEuropean Journal of Combinatorics, 1994
The definitions of descent, exceedance, major index, inversion index and Denert's statistic for the elements of the symmetric group \({\mathcal S}_ d\) are generalized to indexed permutations, i.e. the elements of the group \(S^ n_ d:=\mathbb{Z}_ n\wr{\mathcal S}_ d\), where \(\wr\) is the wreath product with respect to usual action of \({\mathcal S}_ ...

On the lifting of the Dade group

open access: yes, 2018
For the group of endo-permutation modules of a finite \(p\)-group, there is a surjective reduction modulo \(p\) homomorphism from a complete discrete valuation ring of characteristic 0 to its residue field of characteristic \(p\).

On the Phase Sequences and Permutation Functions in the SLM Scheme for OFDM-IM Systems

open access: yesIEEE Access, 2020
In orthogonal frequency division multiplexing with index modulation (OFDM-IM), the active subcarriers can convey information bits by modulated symbols as well as their indices. OFDM-IM has attracted a great deal of attention from researchers by virtue of

Some theoretical foundations for the design and analysis of randomized experiments

open access: yesJournal of Causal Inference
Neyman’s seminal work in 1923 has been a milestone in statistics over the century, which has motivated many fundamental statistical concepts and methodology.

Permutations and Oblong Numbers in the Theravāda-vinaya: A New Intersection of Buddhism and Indian Mathematics

open access: yesReligions
Within the context of Indian religions, Jainism has long been recognized for its extensive use of permutations and combinations. However, the application of these principles within Buddhist scriptures has received relatively little scholarly attention ...

Imaging of High‐Risk Neuroblastoma: Recommendations From SIOPEN Radiology and Nuclear Medicine Specialty Committees

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...

Unfair permutations

open access: yesEuropean Journal of Combinatorics, 2011
We study unfair permutations, which are generated by letting [Formula: see text] players draw numbers and assuming that player [Formula: see text] draws [Formula: see text] times from the unit interval and records her largest value. This model is natural in the context of partitions: the score of the [Formula: see text]th player corresponds to the ...

On the X-rays of permutations

open access: yes, 2005
The X-ray of a permutation is defined as the sequence of antidiagonal sums in the associated permutation matrix. X-rays of permutation are interesting in the context of Discrete Tomography since many types of integral matrices can be written as linear ...

Carcinomas and Carcinoid Tumors of the Lungs and Bronchi in Children and Adolescents: The EXPeRT Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Primary lung carcinomas and bronchial carcinoid tumors (BC) are very rare malignancies in childhood. While typical BC and mucoepidermoid carcinomas are mostly low‐grade, localized tumors with a more favorable prognosis than in adults, necessitating avoidance of overtreatment, adenocarcinomas of the lung are often diagnosed at advanced disease ...

Permutation and sampling with maximum length CA for pseudorandom number generation [PDF]

open access: yes, 2007
In this paper, we study the effect of dynamic permutation and sampling on the randomness quality of sequences generated by cellular automata (CA). Dynamic permutation and sampling have not been explored in previous CA work and a suitable implementation ...
