A 10‐convolutional neural network ensemble using transfer learning and layer freezing analyzes 400 Doppler‐ultrasound spectrograms to distinguish speckle, artifact, and ESs. Soft and hard voting drive performance to 96.7% accuracy and 96.5% F1, highlighting a practical route for early embolus detection and stroke‐risk mitigation.

Multiview subspace clustering via low‐rank correlation analysis
The framework of our proposed method. The unifying graph S is adaptively used to capture the low–rank correlation between samples in different views. S also represents the clustering structure with a rank constraint to avoid its spectral post–processing.

Lined anti-corrosion pipes are widely used in oil and gas, petrochemical, pharmaceutical industries. However, defects, especially delamination, may occur in the production and service of pipes which result in safety accidents.

The frozen natural orbitals (FNO)‐based CCSDT is a cost‐effective approach and provides significant computational speed‐up with rather insignificant errors (standard deviation ∼0.9$\sim 0.9$ millihartrees) – smaller than the CCSDT accuracy limit of ∼1.5$\sim 1.5$ millihartrees.

No‐regret and low‐regret control for a weakly coupled abstract hyperbolic system
Abstract This paper explores an optimal control problem of weakly coupled abstract hyperbolic systems with missing initial data. Hyperbolic systems, known for their wave‐like phenomena and complexity, become even more challenging with weak coupling between subsystems.

Certain isometries related to the bilateral laplace transform
We study certain isometries between Hilbert spaces, which are generated by the bilateral Laplace transform In particular, we construct an analog of the Bargmann‐Fock type reproducing kernel Hilbert space related to this transformation. It is shown

Some new discrete Hilbert’s inequalities involving Fenchel–Legendre transform
Some new Hilbert-type inequalities involving Fenchel–Legendre transform are introduced. These inequalities give more general forms of some previously proved inequalities.

ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Boundedness of the Hilbert Transform on Rearrangement Invariant Spaces
In this self-contained review, the aspects about the applications of decreasing rearrangement techniques to the analysis of pointwise estimates for the Hilbert transform are analyzed. We make a consistent revision of these techniques in the proof of the

Computing the Instantaneous Frequency for AN ECG Signal [PDF]
Physical phenomena have non-stationary nature that cannot be analyzed by conventional numerical methods. The Hilbert-Huang transform is a relatively new way to look at nonstationary signals by introducing the new concept of instantaneous frequency.
