A thorough comprehension of the mechanism behind organic electrooxidation is crucial for development efficient energy conversion technology. Here, we find that trivalent nickel capable oxidizing organics through a nucleophilic attack and electron transfer via nonredox process. This exhibits exceptional kinetic efficiency in possess highest occupied molecular orbital levels ranging from -7.4 to -6 eV (vs. Vacuum level) dual local softness values atoms functional groups, such as hydroxyls...

Introduction: During adulthood, the skin microbiota can be relatively stable if environmental conditions are also stable, yet physiological changes of with age may affect microbiome and its function. The is an important factor to consider in aging since it constitutes most genes that expressed on human body. However, severity specific signs (one parameters used measure “apparent” age) surface quality (e.g., texture, hydration, pH, sebum, etc.) not indicative chronological age. For example,...

Design and development of efficient accurate feature descriptors is critical for the success many computer vision applications. This paper proposes a new descriptor, referred to as DoN, 2D palmprint matching. The descriptor extracted each point on palmprint. It based ordinal measure which partially describes difference neighboring points' normal vectors. DoN has at least two advantages: 1) it 3D information, expected be highly stable under commonly occurring illumination variations during...

This paper introduces a generalized palmprint identification framework to unify several state-of-art 2D and 3D methods. Through this framework, we argue that the methods employing one-to-one matching strategy binary representation for feature are more effective identification. The analysis first argument is based on statistical model supported by outperforming results publicly available palmprpint databases. These two arguments further evaluated used introduce new method encoding feature....

In this paper, we consider the absorption effect for problem of single image reflection removal. We show that can be numerically approximated by average refractive amplitude coefficient map. then reformulate formation model and propose a two-step solution explicitly takes into account. The first step estimates from reflection-contaminated image, while second recovers transmission taking estimated as input. Experimental results on four public datasets our not only successfully removes...

Laser resurfacing is one of the most popular aesthetic procedures that address a wide range skin conditions and overall rejuvenation. To reduce downtime improve clinical efficacy procedures, it important to design post-procedure care routines complement them. Towards fulfilling consumer need, peptide synthesized from multi-component reaction (MCP) has been developed.  The objective this study investigate functionalities MCP as regenerative active enhances healing kinetics anti-aging...

Abstract The direct utilization of dissolved inorganic carbon in seawater for CO 2 conversion promises chemical production on-demand and with zero footprint. Photoelectrochemical (PEC) reduction (CO R) devices promise the sustainable to products using sunlight as only energy input. However, diffusion-dominant transport mechanism near-zero concentration (aq) aqueous solution) static has made it extremely challenging achieve high solar-to-fuel (STF) efficiency carbon-product selectivity. Here,...

The homeostasis of histone methylation is maintained by methyltransferases and demethylases, which are important for the regulation gene expression. Here, we report a demethylase from rice (Oryza sativa), Jumonji C domain-containing protein (JMJ710), belongs to JMJD6 group plays an role in response drought stress. Overexpression JMJ710 causes drought-sensitive phenotype, while RNAi clustered regularly interspaced short palindromic repeats (CRISPR)-knockout mutant lines show tolerance. In...

A photometric stereo method aims to recover the surface normal of a 3D object observed under varying light directions. It is an ill-defined problem because general reflectance properties are unknown. This paper reviews existing data-driven methods, with focus on their technical insights into problem. We divide these methods two categories, per-pixel and all-pixel, according how they process image. discuss differences relationships between from perspective inputs, networks, data, which key...
