To develop and validate a radiomics nomogram for differentiating between malignant pulmonary nodules and benign nodules.56 benign and 51 malignant nodules from 96 patients were analyzed using manual segmentation of the T2-fBLADE-TSE, while the nodule

A directional compactly supported d -dimensional Haar tight framelet is constructed such that all its high-pass filters in its underlying tight framelet filter bank have only two nonzero coefficients with opposite signs and they exhibit totally ( 3 d

In this paper, we show that the univariate interpolatory subdivision schemes with the optimal approximation order, which are the D-D interpolatory ones, can be obtained from the cubic B-spline scheme. Such schemes are derived in this paper by suitabl

The covariance-assisted matching pursuit (CAMP) algorithm has recently been proposed for recovering sparse signals f from noisy linear measurements based on a priori knowledge of the covariance and mean of the nonzero coefficients of f. It utilizes t

This work presents a new mixed (2,p-like)-norm penalized least mean squares (LMS) algorithm for block-sparse system identifications where the nonzero coefficients in the impulse response vector of unknown systems are structured in a single cluster or

This paper focuses on applying a new sign bit hiding method to improve the video coding efficiency. Sign bits account for a large proportion of the encoded stream conforming to the latest high efficiency video coding (HEVC) standard; hence, its hidin

Certain properties of Burchnall–Chaundy polynomials are studied. The first two nonzero coefficients following the leading coefficient are calculated in explicit form. The Dunkl–Darboux differential-difference operators related to the Burchnall–

We obtain new lower bounds for the number of Fourier coefficients of a weakly holomorphic modular form of half-integral weight not divisible by some prime $$\ell $$ l . Among the applications of this we show that there are $$\gg \sqrt{X}/\log \log X$

This chapter revisits, for real polynomials and departing from the fundamental theorem of Algebra, some classical theorems of Calculus. As applications of them, we shall prove Newton’s inequalities, which generalizes the classical inequality betwee

A congruence on \(\mathbb {N}^n\) is an equivalence relation on \(\mathbb {N}^n\) that is compatible with the additive structure. If \(\Bbbk \) is a field, and I is a binomial ideal in \(\Bbbk [X_1,\dots ,X_n]\) (that is, an ideal generated by polyno
