Field Observations of Intermittent Cross‐Shore Bed Load Transport on a Low‐Energy Beach

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 6, June 2026.
Abstract Low‐energy sandy beaches typically have a rippled bed, and the presence of bed forms can strongly affect net sediment transport rates under combined forcing of waves and currents. In case low‐energetic forcing is combined with coarse sediment, bed load transport is an important mechanism to understand transport processes on such beaches.

Some Liouville Theorems on Finsler Manifolds

open access: yesMathematics, 2019
We give some Liouville type theorems of L p harmonic (resp. subharmonic, superharmonic) functions on a complete noncompact Finsler manifold.

Hypercontractivity for log-subharmonic functions

open access: yes, 2010
We prove strong hypercontractivity (SHC) inequalities for logarithmically subharmonic functions on R n and different classes of measures: Gaussian measures on R n , symmetric Bernoulli and symmetric uniform probability measures on R , as well as their ...

Further result on Dirichlet-Sch type inequality and its application

open access: yesJournal of Inequalities and Applications, 2017
In this paper we deal with a theoretical question raised in connection with the application of Dirichlet-Sch type inequality, obtained by Huang (Int. Math. J.

Cohomogeneity‐one solitons in Laplacian flow: Local, smoothly‐closing and steady solitons

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We initiate a systematic study of cohomogeneity‐one solitons in Bryant's Laplacian flow of closed G2$\text{G}_2$‐structures on a 7‐manifold, motivated by the problem of understanding finite‐time singularities of that flow. Here, we focus on solitons with symmetry groups Sp(2)${\rm Sp}(2)$ and SU(3)${\rm SU}(3)$; in both cases, we prove the ...

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.

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.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 20, 27 May 2026.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Subharmonic functions in n-connected domains

open access: yes, 1990
In this paper we investigate some of the properties of harmonic and subharmonic functions defined on n-connected domain G. In particular, we study the behavior of subharmonic functions at every point of the boundary of G.
