A Ce-CuZn catalyst with abundant Cu/Zn-OV-Ce active sites for CO2 hydrogenation to methanol by Runping Ye, Lixuan Ma, Jianing Mao, Xinyao Wang, Xiaoling Hong, Alessandro Gallo, Yanfu Ma, Wenhao Luo, Baojun Wang, Riguang Zhang, Melis Seher Duyar, Zheng Jiang, Jian Liu

“…The Ce-CuZn catalyst exhibits a high methanol selectivity of 71.1% and a space-time yield of methanol up to 400.3 g·kgcat −1·h−1 with excellent stability for 170 h at 260 °C, comparable to that of the state-of-the-art CuZnAl catalysts. Controlled experiments and DFT calculations confirm that the incorporation of Cu and Zn into CeO2 with abundant oxygen vacancies can facilitate H2 dissociation energetically and thus improve CO2 hydrogenation over the Ce-CuZn catalyst via formate intermediates. …”

Polysaccharide Multilayer Films in Sensors for Detecting Prostate Tumor Cells Based on Hyaluronan-CD44 Interactions by João Batista Maia Rocha Neto, Andrey Coatrini Soares, Rogério Aparecido Bataglioli, Olívia Carr, Carlos Alberto Rodrigues Costa, Osvaldo N. Oliveira, Marisa Masumi Beppu, Hernandes F. Carvalho

“…This was achieved by treating the impedance data with information visualization methods, which confirmed the distinguishing ability of the films by observing the absence of false positives in a series of control experiments. The CD44–HA interactions may, therefore, be exploited in clinical analyses and point-of-care diagnostics for cancer, particularly if computational methods are used to process the data.…”

Combining Fe nanoparticles and pyrrole-type Fe-N4 sites on less-oxygenated carbon supports for electrochemical CO2 reduction by Cai Wang, Xiaoyu Wang, Houan Ren, Yilin Zhang, Xiaomei Zhou, Jing Wang, Qingxin Guan, Yuping Liu, Wei Li

“…The combined results of control experiments, in situ characterizations and theoretical calculations demonstrate that introducing Fe nanoparticles can reduce the overpotential by accelerating the proton transfer from CO2 to *COOH and lowering the free energy for *COOH formation, constructing pyrrole-type Fe-N4 sites and limiting oxygen species on carbon supports can increase CO Faraday efficiency through inhibiting the H2 evolution, thus achieving energy-efficient electrochemical CO2 reduction to CO.…”

On equivalence relationships between classification and ranking algorithms by Ertekin, Seyda, Rudin, Cynthia

“…Specifically, we provide such an equivalence relationship between a generalization of Freund et al.’s RankBoost algorithm, called the “P-Norm Push,” and a particular cost-sensitive classification algorithm that generalizes AdaBoost, which we call “P-Classification.”We discuss and validate the potential benefits of this equivalence relationship, and perform controlled experiments to understand P-Classification’s empirical performance. …”

A personalized behavior learning system for human-like longitudinal speed control of autonomous vehicles by Lu, Chao, Gong, Jianwei, Lv, Chen, Chen, Xin, Cao, Dongpu, Chen, Yimin

“…Under the LFD framework, the desired speed of human drivers can be learned by PBLS and converted to the low-level control commands by a proportion integration differentiation (PID) controller. Experiments using driving simulator and real driving data show that PBLS can adapt to different drivers by reproducing their driving behaviors for LSC in different scenes. …”
