Periodic solutions for nonlocal p(t) $p(t)$-Laplacian systems

open access: yesBoundary Value Problems, 2019
The purpose of this paper is to investigate the existence of periodic solutions for a class of nonlocal p(t) $p(t)$-Laplacian systems. When the nonlinear term is p+ $p^{+}$-superlinear at infinity, some new solvability conditions of nontrivial periodic ...

Comparative Study of Platinum(II) and Platinum(IV) Complexes with 2‐(Pyridin‐2‐ylmethylamino)acetic Acid and 4‐(Pyridin‐2‐ylmethylamino)benzoic Acid: Experimental and Theoretical Analysis

open access: yesChemistryEurope, EarlyView.
GA: Ligand precursor 2‐(2‐pyridin‐2‐ylmethylamino)acetic acid (HL1) featuring flexible alkyl chains formed PtII and PtIV complexes with coordination involving the COO‐ group. In contrast, 4‐(2‐pyridin‐2‐ylmethylamino)benzoic acid (HL2) with a rigid p‐phenylene moiety successfully formed the desired PtII and PtIV complexes featuring free carboxylic acid

Reduction of CO2 and Related Compounds with a Low‐Valent CaI Synthon

open access: yesChemistryEurope, EarlyView.
The reduction of CO2, CS2, or carbodiimide with a CaI synthon results in formation of calcium complexes with CO32−, CS22− or C–C coupled carbodiimide dianions. Differences between reduction of these reagents with the CaI synthon and established MgI complexes are discussed. Combined experimental and computational investigations give insight in the first

Effect of Chalcogen Interaction on the Structure of Methine‐Bridged Trichalcogenophenes

open access: yesChemistry – A European Journal, EarlyView.
The stereochemistry of methine‐bridged trichalcogenophenes was elucidated through comprehensive structural analyses. Trithiophene showed a strong preference for the ZZ configuration, whereas its trifuran analog exhibited a near‐statistical distribution of geometric isomers. X‐ray crystallography and computational studies revealed that intramolecular S··

Considering spatiotemporal evolutionary information in dynamic multi‐objective optimisation

open access: yesCAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Preserving population diversity and providing knowledge, which are two core tasks in the dynamic multi‐objective optimisation (DMO), are challenging since the sampling space is time‐ and space‐varying. Therefore, the spatiotemporal property of evolutionary information needs to be considered in the DMO.

Ensemble p-Laplacian Regularization for Remote Sensing Image Recognition [PDF]

open access: yesarXiv, 2018
Recently, manifold regularized semi-supervised learning (MRSSL) received considerable attention because it successfully exploits the geometry of the intrinsic data probability distribution including both labeled and unlabeled samples to leverage the performance of a learning model.

Synthesis and Reactivity of Triphosphaallyl Cation Stabilized by N‐Heterocyclic Carbenes

open access: yesChemistry – A European Journal, EarlyView.
Imidazoliumyl‐substituted triphosphaallyl cations undergo selective P–C bond cleavage and form unprecedented bicyclic P₃‐Ga scaffolds with unique reactivity. Abstract Reduction of the triphosphaallyl species 6[GaCl4] with GaI[Ga2Cl7] affords the imidazoliumyl‐substituted (L) bicyclo[2.1.1]‐triphosphane 10[Ga2Cl7], featuring an unprecedented Ga2Cl5 ...

Mixed eigenvalues of p-Laplacian on trees [PDF]

open access: yesarXiv, 2015
The purpose of the paper is to present quantitative estimates for the principal eigenvalue of discrete p-Laplacian on the set of rooted trees. Alternatively, it is studying the optimal constant of a class of weighted Hardy inequality. Three kinds of variational formulas in different formulation for the mixed principal eigenvalue of p-Laplacian on the ...

Some Liouville Theorems for the p-Laplacian

open access: yes, 2001
We present several Liouville type results for the $p$-Laplacian in $\R^N$. Suppose that $h$ is a nonnegative regular function such that $$ h(x) = a|x|^\gamma\ {\rm for}\ |x|\ {\rm large},\ a>0\ {\rm and}\ \gamma> -p.
