Energy inequalities and dispersive estimates for wave equations with time-dependent coefficients [PDF]

, 2009
We consider wave models with lower order terms and recollect some recent results on energy and dispersive estimates for their solution based on symbolic type estimates for coefficients and partly stabilisation conditions.

Inhibition of IL‐6/STAT3 Signaling by N‐Trans‐Hibiscusamide and Its Derivative in a Mouse Model of Collagen‐Induced Arthritis

Food Science &Nutrition, Volume 14, Issue 3, March 2026.
The IL‐6/STAT3 axis is crucial in rheumatoid arthritis (RA) via Th17 differentiation. The IL‐6/STAT3 signaling pathway is downregulated as a result of the inhibition of IL‐6 and IL‐6R binding by NHA and NAD. NHA and NAD decrease the Th17 differentiation, which lessens the severity of CIA.

Creep failure characteristics and damage creep model of red layer soft rock based on Perzyna viscoplastic theory

Scientific Reports
Rock creep is essentially a process of damage accumulation. According to the damage evolution of rock under creep conditions, the TAW2000 triaxial test system is used to carry out triaxial creep test on red layer soft rock taken from Yibo Tunnel in ...

Dietary Patterns and Risk of Colorectal Cancer Subtypes Classified by Fusobacterium nucleatum in Tumor Tissue [PDF]

, 2018
Importance—Fusobacterium nucleatum appears to play a role in colorectal carcinogenesis through suppression of host immune response to tumor. Evidence also suggests that diet influences intestinal F. nucleatum. However, the role of F.

1D and 3D Carbon Nanomaterials Derived from Zeolite‐Based Catalysts: Synthesis and Applications

Small Structures, Volume 7, Issue 3, March 2026.
Zeolites act as catalysts or catalytic templates to synthesize 1D and 3D carbon nanomaterials with uniform structures, enabled by their high surface area and uniform porous frameworks. The resulting carbon nanomaterials possess excellent surface area and electronic conductivity, supporting their use in energy storage, catalysis, electronics, gas ...

Shock-resolved Navier–Stokes simulation of the Richtmyer–Meshkov instability start-up at a light–heavy interface [PDF]

, 2010
The single-mode Richtmyer–Meshkov instability is investigated using a first-order perturbation of the two-dimensional Navier–Stokes equations about a one-dimensional unsteady shock-resolved base flow. A feature-tracking local refinement scheme is used to

Carboxyl‐Terminal Region of the Maturation Protein of RNA Coliphage Qβ Mediates Host Attachment, Virion Formation, and Cell Lysis

Genes to Cells, Volume 31, Issue 2, March 2026.
The capsid of the single‐stranded RNA coliphage Qβ has a maturation (A2) protein that penetrates the capsid. The N‐terminal β‐region of A2 is exposed on the surface, and the C‐terminal α‐region is located inside the capsid and binds the genomic RNA. In this study, we showed that Qβ attached to the F‐pilus of the host via A2.

The effects of costly exploration on optimal investment timing [PDF]

This paper investigates a principal-agent model in which an owner (principal) optimizes a contract with a manager (agent) delegated to undertake an investment project. In the model, we explore the effects of costly exploration by which the manager learns

Do temporary changes in earnings caused by mean reversion affect firms’ refinancing decisions?

Journal of Financial Research, Volume 49, Issue 1, Page 228-252, Spring 2026.
Abstract We develop a dynamic two‐stage trade‐off model with refinancing when earnings are mean reverting. Our model predicts a negative relation between profitability and leverage at refinancing due to conservative debt increases. With multiple rounds of refinancing, the leverage–profitability relation may turn positive when firms have substantial ...
