Abstract

For a class of parametric modal regression models with measurement error, a simulation extrapolation estimation procedure is proposed in this paper for estimating the modal regression coefficients. Large sample properties of the proposed estimation procedure, including the consistency and asymptotic normality, are thoroughly investigated. Simulation studies are conducted to evaluate its robustness to potential outliers and the effectiveness in reducing the bias caused by the measurement error.

Abstract

The development of bifunctional, non‐noble metal‐based electrocatalysts for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) through morphology and electronic engineering is highly attractive for efficient water splitting. Herein, hierarchical nanoarrays consisting of crystalline cobalt phosphide nanorods covered by amorphous Fe‐doped cobalt phosphide nanocuboids (CoP/FeCoPx) are constructed as bifunctional catalysts for both HER and OER. Experimental results and theoretical calculations reveal that the catalysts exhibit balanced dual‐catalytic properties due to simultaneous introduction of Fe doping and phosphorus vacancies, leading to an optimized electronic structure of the CoP/FeCoPx. Furthermore, the hierarchical nanoarrays made of crystalline/amorphous heterostructures significantly enhance the performance of the electrocatalysts. As a result, the CoP/FeCoPx catalyst demonstrates remarkable performance in both HER and OER, with overpotentials of 74 and 237 mV at 10 mA cm−2 in 1 m KOH, respectively, as well as a low cell voltage of 1.53 V at 10 mA cm−2 for alkaline overall water splitting. This work integrates the morphology engineering involving design of hierarchical crystalline/amorphous nanoarrays and the electronic engineering through Fe doping and phosphorus vacancies for efficient water electrolysis. It may open a new route toward rational design and feasible fabrication of high‐performance, multifunctional, non‐noble metal‐based electrocatalysts for energy conversion. [ABSTRACT FROM AUTHOR]

Abstract

Acquired brain injury (ABI) is an injury that affects the brain structure and function. Traditional ABI treatment strategies, including medications and rehabilitation therapy, exhibit their ability to improve its impairments in cognition, emotion, and physical activity. Recently, near-infrared (NIR) photobiomodulation (PBM) has emerged as a promising physical intervention method for ABI, demonstrating that low-level light therapy can modulate cellular metabolic processes, reduce the inflammation and reactive oxygen species of ABI microenvironments, and promote neural repair and regeneration. Preclinical studies using ABI models have been carried out, revealing the potential of PBM in promoting brain injury recovery although its clinical application is still in its early stages. In this review, we first inspected the possible physical and biological mechanisms of NIR-PBM, and then reported the pathophysiology and physiology of ABI underlying NIR-PBM intervention. Therefore, the potential of NIR-PBM as a therapeutic intervention in ABI was demonstrated and it is also expected that further work can facilitate its clinical applications. [ABSTRACT FROM AUTHOR]
