An isogeometric analysis approach to gradient‐dependent plasticity [PDF]
SummaryGradient‐dependent plasticity can be used to achieve mesh‐objective results upon loss of well‐posedness of the initial/boundary value problem because of the introduction of strain softening, non‐associated flow, and geometric nonlinearity.

Dynamical Systems Approach of Internal Length in Fractional Calculus
Conventionally, non-local properties are included in the constitutive equations in the form of strain gradient-dependent terms. In case of the second gradient dependence an internal material length can be obtained from the critical eigenmodes in ...

VELOCITY GRADIENT OF THE FLOOR EXERCISE [PDF]
The methodological classification of the volume of the exercises is in the basis of the multiannual preparation in gymnastics. A number of authors (Dimitrova, 2015; Borisenko, 2000; Fisenko, 2005; Gaverdovskiy, Smolevskiy, 2014) note that for the ...

In this paper, we study coupled elliptic systems with gradient dependent right-hand sides and nonlinear boundary conditions, where the left-hand sides are driven by so-called double phase operators.

A priori estimate for a quasilinear problem depending on the gradient
AbstractThe main purpose of this paper is to establish a priori estimate for positive solutions of some superlinear, quasilinear elliptic equations where the nonlinearity depends on x, u, and ∇u. Our argument does not need a non-existence result for the limit problem obtained by the usual blow-up procedure.

Infection Models for Pine Wilt Disease on the Basis of Vector Behaviors
Infection models for pine wilt disease without vector density were built to estimate the transmission coefficient of the pathogenic nematode. The models successfully simulated the annual change in the density of infected trees for four pine stands. ABSTRACT Pine wilt disease is caused by the pinewood nematode (Bursaphelenchus xylophilus Steiner et ...

Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

From omics to AI—mapping the pathogenic pathways in type 2 diabetes
Integrating multi‐omics data with AI‐based modelling (unsupervised and supervised machine learning) identify optimal patient clusters, informing AI‐driven accurate risk stratification. Digital twins simulate individual trajectories in real time, guiding precision medicine by matching patients to targeted therapies.

On a Neumann Problem with an Intrinsic Operator
This paper investigates the existence and location of solutions for a Neumann problem driven by a (p,q) Laplacian operator and with a reaction term that depends not only on the solution and its gradient but also incorporates an intrinsic operator, which ...
