Quantitative comparison of sinc-approximating kernels for medical image interpolation [PDF]

, 1999
Interpolation is required in many medical image processing operations. From sampling theory, it follows that the ideal interpolation kernel is the sinc function, which is of infinite extent.

Remarkable properties of the sinc, functions and related integrals

Journal of Mathematical Analysis and Applications, 2021
Abstract Different types of sinc integrals are investigated when the standard sine function is replaced by the generalised sin p , q in two parameters. A striking generalisation of the improper Dirichlet integral is achieved. A second surprising but interesting generalisation of the identity between the Dirichlet integral and that of ...

Brown Adipocyte Sheets Alleviate Myocardial Ischemia–Reperfusion Injury Through NRG4–ErbB4–Dependent Ferroptosis Inhibition

Advanced Science, EarlyView.
Brown adipocyte sheets are engineered to protect the heart against myocardial ischemia–reperfusion injury by restraining ferroptosis. Upon transplantation onto the cardiac surface, they improve cardiac function, limit infarction and fibrosis, and enhance angiogenesis.

Numerical method based on sinc functions for solving singularly perturbed Fredholm integro-differential equations

Boundary Value Problems
A numerical method based on sinc functions is developed and examined to approximate the solution of singularly perturbed Fredholm integro-differential equations. This method involves combining sinc basis functions with nonclassical weight functions. With

Master Regulator SMC1A, Stabilized by N6‐Methyladenosine Reader IGF2BP1, Promotes HCC Progression Through Facilitating Enhancer–Promoter Interaction of Nestin

Advanced Science, EarlyView.
IGF2BP1‐mediated m6A stabilization sustains SMC1A expression, enabling cohesin‐associated chromatin regulation of Nestin in hepatocellular carcinoma. This work reveals an epitranscriptomic‐chromatin‐cytoskeletal regulatory axis linked to malignant phenotypes and identifies SMC1A as a biologically relevant vulnerability in HCC.

PSLL and HPBW Minimisation in Time‐Variant FDA Using Sum‐of‐Sinc‐Functions‐Based Frequency Offsets

IET Microwaves, Antennas & Propagation
Beampattern of a frequency diverse array (FDA) is a function of time, range and angle. The shape of this beampattern is dependent on the frequency offsets (FO) that are applied to each element. These FO are sampled from a window function whose parameters

A sinc quadrature subroutine for Cauchy principal value integrals

, 1999
A subroutine is presented for the evaluation of Cauchy principal value integrals. Based on a truncated sum of a Sinc function series, with the function evaluated at shifted Sinc points, the subroutine returns an approximation to the integral together ...

Lactoferrin Deficiency During Lactation Causes Adult Obesity‐Related Metabolic Disease Through Persistent Adipose Dysfunction Driven by Impaired Adipocyte Development

Advanced Science, EarlyView.
Lactational lactoferrin deficiency exerts lasting effects on epididymal adipose tissue development from lactation into adulthood: it impairs adipocyte hyperplasia and induces pathological hypertrophy, resulting in lower body weight yet exacerbated metabolic dysfunction under a high‐fat diet in adulthood.

Compact Tabletop Magnetic Resonance Elastography for Mapping Soft Tissue Viscoelasticity

Advanced Science, EarlyView.
This work introduces a compact, low‐cost tabletop magnetic resonance elastography platform for high‐resolution viscoelastic mapping in soft‐tissue specimens. Using this method in human colorectal liver metastases, we demonstrate fully automated biomechanical profiling of treatment response and show that heterogeneity‐based metrics outperform ...
