Low-Dose CT Denoising via Sinogram Inner-Structure Transformer

Liutao Yang, Zhongnian Li, Rongjun Ge +3

Low-Dose Computed Tomography (LDCT) technique, which reduces the radiation harm to human bodies, is now attracting increasing interest in the medical imaging field. As the image qu…

On the number of zeros to the equation $f (x_{1}) + ... + f (x_{n}) = a$ over finite fields

Chaoxi Zhu, Yulu Feng, Shaofang Hong +1

Let $p$ be a prime, $k$ a positive integer and let $F_{q}$ be the finite field of $q = p^{k}$ elements. Let $f (x)$ be a polynomial over $F_{q}$ and $a \in F_{q}$ . We d…

Sums of polynomial-type exceptional units modulo $n$

Junyong Zhao, Shaofang Hong, Chaoxi Zhu

Let $f (x) \in Z [x]$ be a nonconstant polynomial. Let $n, k$ and $c$ be integers such that $n \geq 1$ and $k \geq 2$ . An integer $a$ is called an $f$ -exunit in the ring $\mathbb{…

A certain reciprocal power sum is never an integer

Junyong Zhao, Shaofang Hong, Xiao Jiang

By $(Z^{+})^{\infty}$ we denote the set of all the infinite sequences $S = {s_{i}}_{i = 1}^{\infty}$ of positive integers (note that all the $s_{i}$ are not necessarily…

Counting rational points of an algebraic variety over finite fields

Shuangnian Hu, Shaofang Hong, Xiaoer Qin

Let $F_{q}$ denote the finite field of odd characteristic $p$ with $q$ elements ( $q = p^{n}, n \in N$ ) and $F_{q}^{*}$ represent the nonzero elements of $\mathbb{…
