PDE-PRESERVING PROPERTIES [PDF]

Journal of the Korean Mathematical Society, 2005
A continuous linear operator \(T\) on the space of entire functions in \(d\) variables is called PDE-preserving for a given set \(\mathbb{P}\subseteq\mathbb{C}[\xi_1,\ldots,\xi_d]\) of polynomials if \(T\ker P(D)\subseteq P(D)\) for all \(P\in\mathbb P\), where \(P(D)\) is the differential operator obtained by replacing each variable \(\xi_j\) by ...

Rib‐Reinforced Ultralight and Ultra‐Strong Shell Lattices

Advanced Science, EarlyView.
This study thoroughly reveals the relation between the curvature and stress direction of triply periodic minimal surface (TPMS) thin shell lattices and proposes a novel rib reinforcement design strategy to incorporate ribs along the line of asymptotes (LOA) and the line of principal curvatures (LOC) to enhance the strength of ultralight TPMS shell ...

A penalty method for PDE-constrained optimization in inverse problems

, 2015
Many inverse and parameter estimation problems can be written as PDE-constrained optimization problems. The goal, then, is to infer the parameters, typically coefficients of the PDE, from partial measurements of the solutions of the PDE for several right-

Bifidobacterium Breve Yang08 Alleviates Atopic Dermatitis By Enriching Akkermansia Muciniphila and Inhibiting Neutrophil Extracellular Traps Formation In Mice

Advanced Science, EarlyView.
A novel Bifidobacterium breve strain, Yang08, is isolated to counter its depletion in atopic dermatitis. In mice, live Yang08 requires an intact gut microbiota to exert protection, specifically enriching Akkermansia muciniphila and potently inhibiting pathogenic neutrophil activation and NETosis in the skin.

Portopulmonary hypertension practice patterns after liver transplantation

Liver Transplantation, EarlyView., 2022
Abstract Portopulmonary hypertension (POPH) is a type of pulmonary arterial hypertension occurring exclusively in those with portal hypertensive liver disease. Liver transplantation (LT) can significantly improve outcomes. Current guidelines counsel against immediate adjustments to targeted therapy after LT and suggest routine echocardiography as ...

Homogeneous two-point problem for PDE of the second order in time variable and infinite order in spatial variables

Open Mathematics, 2017
We prove that homogeneous problem for PDE of second order in time variable, and generally infinite order in spatial variables with local two-point conditions with respect to time variable, has only trivial solution in the case when the characteristic ...

miR‐135a‐5p Is a Promising Target to Prevent the Glomerulosclerosis Associated with Podocyte Developmental Toxicity in Offspring Induced by Prenatal Dexamethasone Exposure

Advanced Science, EarlyView.
Prenatal dexamethasone exposure (PDE) programs persistent podocyte developmental injury and adult glomerulosclerosis. Mechanistically, glucocorticoid receptor (GR) binds the miR‐135a‐5p promoter and recruits the histone acetyltransferase p300, increasing promoter histone acetylation and sustaining miR‐135a‐5p expression. Elevated miR‐135a‐5p suppresses

Conformal geometry of surfaces in the Lagrangian--Grassmannian and second order PDE

, 2010
Of all real Lagrangian--Grassmannians $LG(n,2n)$, only $LG(2,4)$ admits a distinguished (Lorentzian) conformal structure and hence is identified with the indefinite M\"obius space $S^{1,2}$.

Physical Implementation of Optical Material‐Based Neural Networks Processing Enabled by Long‐Persistent Luminescence

Advanced Science, EarlyView.
This study reports on the physical implementation of optical material‐based neural processing using long‐persistent luminescence as memory‐retention and nonlinear optical material. The system performs optical‐domain preprocessing with opto‐electronic interfaces for stimulus delivery and readout, enabling real‐time demonstrations including Pong gameplay
