A boundary element and radial basis function approximation method for a second order elliptic partial differential equation with general variable coefficients

open access: yesEngineering Reports, 2019
A numerical method based on boundary integral equation and radial basis function approximation is presented for solving boundary value problems governed by a second‐order elliptic partial differential equation with variable coefficients.

On Finite Product of Convolutions and Classifications of Hyperbolic and Elliptic Equations [PDF]

open access: yesarXiv, 2009
In this paper we consider the linear second order partial differential equation with non-constant coefficients; then by using the double convolution product we produce new equations with polynomials coefficients and we classify the new equations. It is shown that the classifications of hyperbolic and elliptic new equations are similar to the original ...

A Multifunctional Nanodelivery System Modified by Fusion Peptides Acts as Teriparatide Carrier for Noise‐Induced Hearing Loss Therapy

open access: yesAdvanced Science, EarlyView.
The fusion peptide LR27‐modified thermosensitive nanodelivery system exhibits both hair cell targeting and inner ear penetrating properties. This system sustainably and effectively delivers PTH1‐34 to the inner ear of a hearing loss mouse model via the synergistic effects of multiple peptides, achieving satisfactory hearing protection through ...

Existence of solutions for a degenerate seawater intrusion problem

open access: yesElectronic Journal of Differential Equations, 2005
We study a seawater intrusion problem in a confined aquifer. This process can be formulated as a coupled system of partial differential equations which includes an elliptic and a degenerate parabolic equation.

SIRT3‐Mediated Deacetylation of DRP1K711 Prevents Mitochondrial Dysfunction in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
SIRT3‐mediated deacetylation of DRP1 at K711 resists mitochondrial dysfunction and DA neuronal death in PD, uncovering a treatment target. Abstract Dysregulation of mitochondrial dynamics is a key contributor to the pathogenesis of Parkinson's disease (PD).

A computed tomography‐based survey of paramedullary diverticula in extant Aves

open access: yesThe Anatomical Record, Volume 306, Issue 1, Page 29-50, January 2023., 2023
Abstract Avian respiratory systems are comprised of rigid lungs connected to a hierarchically organized network of large, regional air sacs, and small diverticula that branch from them. Paramedullary diverticula are those that rest in contact with the spinal cord, and frequently invade the vertebral canal.

Delivery of Human iPSC‐Derived RPE Cells in Healthy Minipig Retina Results in Interaction Between Photoreceptors and Transplanted Cells

open access: yesAdvanced Science, EarlyView.
Human induced pluripotent stem cell‐derived retinal pigment epithelial (hiPSC‐RPE) cells, cultured on a clinically relevant PDLLA scaffold, are transplanted into immunosuppressed minipigs. The study demonstrates the viability, integration, and preservation of RPE‐specific features without gliosis or neuroinflammation, supporting their potential as a ...
