A new application of boundary integral behaviors of harmonic functions to the least harmonic majorant

open access: yesBoundary Value Problems, 2017
Our main aim in this paper is to obtain a new type of boundary integral behaviors of harmonic functions in a smooth cone. As an application, the least harmonic majorant of a nonnegative subharmonic function is also given.

Microbubble‐Based Ultrasound Contrast Agents in Contrast‐Enhanced Ultrasonography for Managing Portal Hypertension in Cirrhosis

open access: yesPortal Hypertension &Cirrhosis, Volume 5, Issue 3, Page 260-268, September 2026.
As the hepatic venous pressure gradient (HVPG) remains the current gold standard for diagnosing portal hypertension in cirrhosis, its clinical application is limited by invasiveness, high cost, and restricted availability. Given the urgent need for noninvasive techniques to dynamically monitor portal vein pressure (PVP), contrast‐enhanced ...

Subharmonic functions, generalizations and separately subharmonic functions

open access: yes, 2006
First, we give the definition for quasi-nearly subharmonic functions, now for general, not necessarily nonnegative functions, unlike previously. We point out that our function class incudes, among others, quasisubharmonic functions, nearly subharmonic functions (in a slightly generalized sense) and almost subharmonic functions.

A Systematic Review of Data Science in Early Voice‐Based Detection of Parkinson's and Amyotrophic Lateral Sclerosis Neurodegenerative Diseases

open access: yesWIREs Data Mining and Knowledge Discovery, Volume 16, Issue 3, September 2026.
Seven‐stage AI‐powered voice biomarker pipeline for neurodegenerative disease diagnosis and clinical decision support. ABSTRACT Recent studies have shown that voice analysis provides a feasible, non‐invasive diagnostic alternative for the early detection of neurodegenerative diseases (NDs), such as Parkinson's disease (PD) and Amyotrophic Lateral ...

Field‐Programable Dynamics in a Soft Magnetic Actuator Enabling True Random Number Generation and Reservoir Computing

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 8, August 2026.
Complex dynamics, often avoided in electromechanical design, can enhance soft robotics. We develop durable magnetic soft actuators operating in tunable dynamic regimes, enabling random number generation, stochastic computing, and time‐series prediction.

FREQ‐NESS Reveals Age‐Related Differences in Frequency‐Resolved Brain Networks During Auditory Recognition and Resting State

open access: yesAnnals of the New York Academy of Sciences, Volume 1562, Issue 1, August 2026.
We adapted the FREQ‐NESS pipeline to event‐related MEG data from 140 adults during a melody‐recognition task, revealing an age‐related reorganization of frequency‐specific brain networks. Younger adults showed task‐related reduction in the prominence of alpha networks, whereas older adults maintained prominent slower alpha networks (8.6–10.0 Hz) across

On modified Bitsadze–Samarskiy problem

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
We study the non-local boundary value problem which is an analogue of the Bitsadze–Samarskiy problem. For the two-dimensional case we reduce this problem to the local boundary value problem, more exactly to the Dirichlet problem for the analogue of the ...

Investigation on the Nonlinear Vibration Characteristics of Current-Carrying Crescent Iced Conductors under Aerodynamic Forces, Ampere’s Forces, and Forced Excitation Conditions

open access: yesDiscrete Dynamics in Nature and Society, 2021
Aiming at the problem of nonlinear vibration of current-carrying iced conductors, the aerodynamic forces are introduced into the previous vibration equation of current-carrying conductors that only considered Ampere’s forces.

Embodied Responses to Harmony and (Poly)Rhythm: An Integrated Ratio‐Based Perception‐Action Framework

open access: yesAnnals of the New York Academy of Sciences, Volume 1562, Issue 1, August 2026.
Harmony and rhythm perception are often studied separately, yet both reveal a shared sensitivity to low‐order integer ratios. In harmony, intervals like the octave (2:1) and fifth (3:2) predict consonance and ease of encoding. In rhythm, patterns with simple ratios (e.g., 2:1, 3:2) are easier to perceive, reproduce, and remember.
