Four-variable expanders over the prime fields [PDF]

Proceedings of the American Mathematical Society, 2018
Let F p \mathbb {F}_p be a prime field of order p > 2 p>2 , and let A A be a set in F p \mathbb {F}_p with very small size in terms of p p .

Tanner (3, 23)-Regular QC-LDPC Codes: Cycle Structure and Girth Distribution

IEEE Access
This paper studies a class of quasi-cyclic LDPC (QC-LDPC) codes, i.e., Tanner (3, 23)-regular QC-LDPC codes of code length $23p$ with $p$ being a prime and $p \equiv 1 (\mathrm {mod} 69)$ .

A collaborative resource platform for non-human primate neuroimaging

NeuroImage, 2021
Neuroimaging non-human primates (NHPs) is a growing, yet highly specialized field of neuroscience. Resources that were primarily developed for human neuroimaging often need to be significantly adapted for use with NHPs or other animals, which has led to ...

On the divergence of two subseries $\ldots$] {on the divergence of two subseries of $\sum\frac{1}{p}$, and theorems of de La Vall\'{e}e Poussin and Landau-Walfis

Boletim da Sociedade Paranaense de Matemática, 2022
Let $K=Q(\sqrt{d})$ be a quadratic field with discriminant $d$. It is shown that $\sum\limits_{(\frac{d}{p})=+1,_{p~ prime}}\frac{1}{p}$ and $\sum\limits_{(\frac{d}{q})=-1,_{q~ prime}}\frac{1}{q}$ are both divergent.

COMP Report: CPQR technical quality control guidelines for use of positron emission tomography/computed tomography in radiation treatment planning

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Positron emission tomography with x‐ray computed tomography (PET/CT) is increasingly being utilized for radiation treatment planning (RTP). Accurate delivery of RT therefore depends on quality PET/CT data. This study covers quality control (QC) procedures required for PET/CT for diagnostic imaging and incremental QC required for RTP.

Floquet engineering of tilted and gapped Dirac bandstructure in 1T $$^\prime$$ ′ -MoS $$_2$$ 2

Scientific Reports, 2022
We have developed a rigorous theoretical formalism for Floquet engineering, investigating, and subsequently tailoring most crucial electronic properties of 1T $$^\prime$$ ′ -MoS $$_2$$ 2 by applying an external high-frequency dressing field within the ...

The application of multiple metrics in deformable image registration for target volume delineation of breast tumor bed

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Background and purpose For postoperative breast cancer patients, deformable image registration (DIR) is challenged due to the large deformations and non‐correspondence caused by tumor resection and clip insertion. To deal with it, three metrics (fiducial‐, region‐, and intensity‐based) were jointly used in DIR algorithm for improved accuracy ...

On the Common Index Divisors of a Dihedral Field of Prime Degree

International Journal of Mathematics and Mathematical Sciences, 2007
A criterion for a prime to be a common index divisor of a dihedral field of prime degree is given. This criterion is used to determine the index of families of dihedral fields of degrees 5 and 7.

On the gap between prime ideals

AIMS Mathematics, 2019
We define a gap function to measure the difference of two distinct prime ideals in a given number field. In this paper, we determine all quadratic fields and cyclotomic fields satisfying the condition: There exist two distinct prime ideals whose gap is 1.

Repetition-priming effect: a cognitive task for the definition of a clinical assessment [PDF]

Neuropsychological Trends, 2014
This research aims to study how semantic priming words can influence behavioral measures (RTs, accuracy), to develop an experimental paradigm to differentiate visual neglect and hemianopia. 69 experimental subjects were involved in four experiments.
