9. Optimal Combinatorial Neural Codes with Matched Metric $\delta_{r}$: Characterization and Constructions

Abstract

Based on the theoretical neuroscience, G. Cotardo and A. Ravagnavi in \cite{CR} introduced a kind of asymmetric binary codes called combinatorial neural codes (CN codes for short), with a "matched metric" $\delta_{r}$ called asymmetric discrepancy, instead of the Hamming distance $d_{H}$ for usual error-correcting codes. They also presented the Hamming, Singleton and Plotkin bounds for CN codes with respect to $\delta_{r}$ and asked how to construct the CN codes $\cC$ with large size $|\cC|$ and $\delta_{r}(\cC).$ In this paper we firstly show that a binary code $\cC$ reaches one of the above bounds for $\delta_{r}(\cC)$ if and only if $\cC$ reaches the corresponding bounds for $d_H$ and $r$ is sufficiently closed to 1. This means that all optimal CN codes come from the usual optimal codes. %(perfect codes, MDS codes or the codes meet the usual Plotkin bound). Secondly we present several constructions of CN codes with nice and flexible parameters $(n,K, \delta_r(\cC))$ by using bent functions., Comment: 19pages,two figures,regular paper

42. Interface-engineered hybrid electrocatalysts of Ti@holey-TiN/layered-double-hydroxides for efficient seawater electrolysis.

Author

Abstract

Interface structures have received significant attention because of their profound influence on the catalytic activities of nanostructured materials. Although energy-functional hybrid materials have been researched, there are no reports on using Ti@holey TiN foam as a hybridization matrix for high-performance electrocatalysts in seawater. In addition, the impact of a defective buffer layer on interfacial electronic coupling and electrocatalytic activity needs to be systematically investigated. In this study, we develop an interface engineering route to explore high-performance hybrid electrocatalysts for seawater electrolysis by introducing holey TiN nanoplates as buffer layers on the surface of a Ti foam. Hierarchical hybrid electrocatalysts of Ti@holey-TiN/Ni–Fe-layered double hydroxide (LDH) are synthesized by the sequential oxidation–nitridation of a Ti foam, followed by the deposition of LDH. The obtained Ti@holey-TiN/LDH nanohybrids display an outstanding performance as an oxygen evolution electrocatalyst with small overpotentials of 240 and 250 mV at 100 mA cm−2 in an aqueous 1 M KOH solution and simulated alkaline seawater electrolyte, respectively. In situ spectroscopic analysis confirms the merits of holey TiN buffer layers in reinforcing interfacial electronic coupling with deposited LDH species and immobilizing the stoichiometric LDH phase, resulting in an increase in reaction kinetics of the LDH phase during the oxygen evolution reaction. The benefits of the hierarchical porous hybrid structure on the catalytic activity of seawater electrocatalysis can be ascribed to the enhanced electrical connection between the LDH and Ti substrate, provision of many electrochemically active sites, promotion of charge/mass transfer kinetics, and improved hydroxide adsorption selectivity.

Abstract

It is important to tune the coordination configuration of dual‐atom catalyst (DAC), especially in the first coordination sphere, to render high intrinsic catalytic activities for oxygen reduction/evolution reactions (ORR/OER). Herein, a type of atomically dispersed and boron‐coordinated DAC structure, namely, FeN4B‐NiN4B dual sites, is reported. In this structure, the incorporation of boron into the first coordination sphere of FeN4/NiN4 atomic sites regulates its geometry and electronic structure by forming "Fe‐B‐N" and "Ni‐B‐N" bridges. The FeN4B‐NiN4B DAC exhibits much enhanced ORR and OER property compared to the FeN4‐NiN4 counterparts. Density functional theory calculations reveal that the boron‐induced charge transfer and asymmetric charge distributions of the central Fe/Ni atoms optimize the adsorption and desorption behavior of the ORR/OER intermediates and reduce the activation energy for the potential‐determining step. Zinc‐air batteries employing the FeN4B‐NiN4B cathode exhibit a high maximum power density (236.9 mW cm−2) and stable cyclability up to 1100 h. The result illustrates the pivotal role of the first‐coordination sphere of DACs in tuning the electrochemical energy conversion and storage activities. [ABSTRACT FROM AUTHOR]

Abstract

Pneumocystis jirovecii pneumonia (PJP) in advanced prostatic cancer patients not receiving high-dose glucocorticoids has been reported rarely. A 73-year-old man underwent chemotherapy with cisplatin and docetaxel for advanced prostatic cancer. After nine cycles of chemotherapy, he developed a high fever, dry cough, shortness of breath, and severe fatigue, with rapid-onset hypoxic respiratory failure. Investigations demonstrated bilateral ground-glass opacities with positive bronchoalveolar lavage fluid (BALF) for Pneumocystis jirovecii by next-generation sequencings (NGS). The patient recovered well with treatment with trimethoprim-sulfamethoxazole, caspofungin, and corticosteroids. This case report describes a case of PJP in a patient with a solid tumor who did not receive high-dose glucocorticoids and emphasizes the importance of early diagnosis and treatment.
