Free Vibration Analysis of Arbitrary-Shaped Plates Based on the Improved Rayleigh–Ritz Method

Advances in Civil Engineering, 2019
In this investigation, an improved Rayleigh–Ritz method is put forward to analyze the free vibration characteristics of arbitrary-shaped plates for the traditional Rayleigh–Ritz method which is difficult to solve.

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

Journal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

Phenotypic integration and the organization of discrete facial variation

Journal of Anatomy, EarlyView.
Integration patterns shape the prevalence of discrete facial trait combinations. Abstract Facial morphology results from coordinated developmental and evolutionary processes that produce structured patterns of covariation among traits. Therefore, individual faces reflect integrated anatomical configurations rather than collections of isolated traits ...

Asymmetric Pass‐Through and Competition

The Journal of Industrial Economics, EarlyView.
ABSTRACT We study the retail price pass‐through of four major tax changes in petroleum products using daily pricing data from gas stations on small Greek islands. We find that (i) the pass‐through of the tax hikes is five times higher than for the tax decrease, (ii) the pass‐through of the tax hikes increases with competition, while that of the tax ...
