On the number of singular points of weak solutions to the Navier‐Stokes equations
Communications on Pure and Applied Mathematics, 2001 AbstractWe consider a suitable weak solution to the three‐dimensional Navier‐Stokes equations in the space‐time cylinder Ω × ]0, T[. Let Σ be the set of singular points for this solution and Σ (t) ≡ {(x, t) ∈ Σ}. For a given open subset ω ⊆ Ω and for a given moment of time t ∈]0, T[, we obtain an upper bound for the number of points of the set Σ(t) ⋒ ω.

On the number of determining nodes for the 2D Navier-Stokes equations
Journal of Mathematical Analysis and Applications, 1992 The authors consider a two-dimensional problem for the Navier-Stokes system with periodic boundary conditions \[ u_ t-\nu \Delta u+(u\cdot\nabla)u+\nabla p=f, \qquad \nabla\cdot u=0, \qquad x\in R^ 2, \qquad t>0,\tag{1} \] \(u(x_ 1,x_ 2,t)=u(x_ 1,x_ 2+L,t)\), \(u(x_ 1,x_ 2,t)=u(x_ 1+L,x_ 2,t)\). Let \({\mathcal E}=\{x^ 1,\dots, x^ N\}\) be a collection

Advanced Science, EarlyView.ABSTRACT Self‐healing materials represent a paradigm shift in designing functional biomedical devices for drug delivery, tissue regeneration, and 3D bioprinting. However, their clinical translation remains limited by challenges such as insufficient mechanical strength, potential cytotoxicity from chemical modifications, and complex activation ...

Advanced Science, EarlyView.A nanoparticle‐cluster‐on‐mirror (NPcoM) serves as a functionally deterministic sub‐nanocavity that emulates picocavities, enabling extreme light–matter interactions and polaritonic phenomena. ABSTRACT Pushing nanoscale optical confinement to its ultimate limits defines the regime of nano‐cavity quantum electrodynamics (nano‐cQED), where light‐matter ...

Advanced Science, EarlyView.Regulation of molecular packing, phototoxicity, and ROS output of AIE photosensitizers is achieved through carboxylation and alkyl‐chain‐length tuning. The probe designed via this strategy enables super‐resolution visualization of inner‐mitochondrial‐membrane cristae dynamics under controlled oxidative stress, and fluorescence‐lifetime imaging of ...
