The periderm provides a protective barrier in many seed plant species. development of the suberized phellem, which forms outermost layer this important tissue, has become trait interest for enhancing both resilience to stresses and plant-mediated CO
This paper is devoted to the existence of infinitely many solutions for a class Kirchhoff-type equations setting on \documentclass[12pt]{minimal}\begin{document}$\mathbb {R}^N$\end{document}RN. Based minimax methods in critical point theory, we obtain large-energy and small-energy solutions, which unify sharply improve recent results Wu [“Existence nontrivial high energy Schrödinger–Kirchhoff-type RN,” Nonlinear Anal.: Real World Appl. 12, 1278–1287 (2011)].
In this paper, we study the existence of infinitely many periodic solutions for non-autonomous second-order Hamiltonian systems with symmetry. Based on minimax methods in critical point theory, particular, fountain theorem Bartsch and symmetric mountain pass lemma due to Kajikiya, obtain results both superquadratic case subquadratic case, which unify sharply improve some recent literature.
In this paper, we study the second‐order perturbed Hamiltonian systems urn:x-wiley:00222526:sapm12023:equation:sapm12023-math-0001 where is a parameter, positive definite for all but unnecessarily uniformly , and W either asymptotically quadratic or superquadratic in x as . Based on variational methods, prove existence of at least two nontrivial homoclinic solutions above system when small enough.
The Arabidopsis thaliana ASYMMETRIC LEAVES2 ( AS2 ) gene is responsible for the development of flat, symmetric, and extended leaf laminae their veins. belongs to plant-specific AS2-LIKE/LATERAL ORGAN BOUNDARIES LOB )-domain ASL/LBD ), which consists 42 proteins in with a conserved amino-terminal domain known as AS2/LOB domain, variable carboxyl-terminal region. an (N-terminal) that contains cysteine repeat (the C-motif), glycine residue, leucine-zipper-like. has been characterised plants...
Cassava ( Manihot esculenta Crantz) is an important tropical crop for food, fodder, and energy. bacterial blight (CBB) caused by Xanthomonas axonopodis pv. manihotis Xam ) occurs in all cassava growing regions threatens global production. WRKY transcription factor family plays the essential roles during plant growth, development, abiotic or biotic stress. Particularly, previous studies have revealed role of group IIa genes disease resistance. However, a comprehensive analysis subfamily still...
Receptor-like cytoplasmic kinases (RLCKs) play important roles in various developmental processes and stress responses plants. Whereas, the detailed information of this family cassava has not clear yet. In study, A total 322 MeRLCK genes were identified genome, they could be divided into twelve clades (Clades I-XII) according to their phylogenetic relationships. Most RLCK members same clade have similar characteristics motif compositions. Over half RLCKs possess cis-elements promoters that...
In the case of constructing underground water-sealed oil storage caverns in island environments, groundwater seepage characteristics are more complicated under influence seawater and tidal fluctuations. It also faces problems such as intrusion. This research is based on multi-physical field coupling theory analyzed fluctuation water curtain systems temporal-spatial variations intrusion an cavern China using finite element method. The results show that operation environment has a risk...

Via variational methods, prove existence of ground state solution.
In this paper, we study the existence of nontrivial solutions and ground state for second order Hamiltonian systems: $$ \ddot u(t)+A(t)u(t)+\nabla F(t,u(t))=0\ \ \mbox{a.e. } t\in [0,T], where $A(t)$ is a $N\times N$ symmetric matrix, continuous $T$-periodic in $t$. Replacing classical Ambrosetti-Rabinowitz superquadratic condition by general condition, prove some theorems, which unify improve recent results literature.

Energy stored in the resonant inductor is critical to zero-voltage switching (ZVS) of power semiconductor devices soft-switching active-clamping three-phase inverters. Traditionally, pulse width modulation (PWM) timing parameters are designed based on calibrated data table. However, for motor drives or general-purpose ac supplies, their fundamental output amplitude and frequency may vary, which makes control inverter complex. It would be time-consuming tiring manually calibrate under various...

Furthermore, if even in $x$, prove infinitely many general u(t)+A(t)u(t)+\nabla $A(\cdot)$ a continuous $T$-periodic symmetric matrix. Our theorems mainly improve recent result Tang and Jiang [X.H.
