Novel Bernstein‐Kantorovich Type Operators

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we introduce a novel class of Bernstein‐Kantorovich operators, denoted as Kβn,θ$$ {K}_{\beta}^{n,\theta } $$, parameterized by 0<β<1$$ 0<\beta <1 $$ and θ>0$$ \theta >0 $$. We first derive a recurrence formula that facilitates the computation of moments and central moments and provide explicit expressions for Kβn,θ(tm;x)$$ {K}_{\

Multi‐Contrast Human Brain CEST MRI at 11.7 T: First In Vivo Demonstration

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT PurposeTo implement and evaluate chemical exchange saturation transfer (CEST) at ultra‐high field on a whole‐body 11.7 T scanner using parallel transmission (pTx). MethodsTailored pTx CEST saturation pulses were optimized to achieve a spatially uniform target B1+ while satisfying SAR and power constraints either defined by conservatively ...

Accelerating Stroke MRI With Diffusion Probabilistic Models Through Large‐Scale Pre‐Training and Target‐Specific Fine‐Tuning

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a data‐efficient strategy for accelerated MRI reconstruction with Diffusion Probabilistic Generative Models (DPMs) that enables faster scan times in clinical stroke MRI when only limited fully‐sampled data are available. Methods Our simple training strategy first pre‐trains a DPM on a large, diverse collection of publicly ...

Training Deep Learning Based Dynamic MR Image Reconstruction Using Synthetic Fractals

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate whether synthetically generated fractal data can be used to train deep learning (DL) models for dynamic MRI reconstruction, thereby avoiding the privacy, licensing, and availability limitations associated with cardiac MR training datasets.

1D Pre‐Acquisition Navigator Correcting Respiratory‐Induced Field Fluctuations in Multi‐Echo Gradient‐Echo Imaging of the Thoracic Spinal Cord

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose In the spinal cord (SC), multi‐echo gradient echo (ME‐GRE) increases gray (GM) and white matter (WM) contrast and improves sensitivity to lesions in people with multiple sclerosis (pwMS). However, SC ME‐GRE is susceptible to breathing‐induced field fluctuations, causing ghosting artifacts and signal loss.

Modeling Biocemented Sands: Hypoplastic Model for MICP‐Based Ground Improvement

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Bio‐cementation offers a sustainable and low‐carbon alternative to conventional ground improvement methods, aligning with the growing demand for green geotechnical solutions. To enable reliable numerical simulation of bio‐cemented soil behavior in engineering applications, advanced constitutive models are required to account for the effects of
