Fully automated hybrid approach on conventional MRI for triaging clinically significant liver fibrosis: A multi‐center cohort study

Jun‐hao Zha, Tian‐yi Xia, Zhi‐yuan Chen, Tian‐ying Zheng, more

Journal of Medical Virology > 96 > 8 > n/a - n/a

Establishing reliable noninvasive tools to precisely diagnose clinically significant liver fibrosis (SF, ≥F2) remains an unmet need. We aimed to build a combined radiomics‐clinic (CoRC) model for triaging SF and explore the additive value of the CoRC model to transient elastography‐based liver stiffness measurement (FibroScan, TE‐LSM). This retrospective study recruited 595 patients with biopsy‐proven...

Elucidation of factors contributing to onset of Cercospora leaf blight during later reproductive development of soybean

Marija Zivanovic, Brian Ward, Paul P. Price, Zhi‐Yuan Chen

Plant Pathology > 70 > 9 > 2074 - 2085

In Louisiana, Cercospora leaf blight (CLB) of soybean is primarily caused by Cercospora cf. flagellaris, which can be detected in asymptomatic leaves as early as V3 (third trifoliate) growth stage, while symptoms appear around R5 (beginning seed). The fungus produces cercosporin, an important virulence factor, the in vitro production of which is significantly reduced in the absence of simple sugars...

Reduction of Phakopsora pachyrhizi infection on soybean through host‐ and spray‐induced gene silencing

Dongfang Hu, Zhi‐Yuan Chen, Chunquan Zhang, Mala Ganiger

Molecular Plant Pathology > 21 > 6 > 794 - 807

Asian soybean rust (ASR), caused by the obligate fungal pathogen Phakopsora pachyrhizi, often leads to significant yield losses and can only be managed through fungicide applications currently. In the present study, eight urediniospore germination or appressorium formation induced P. pachyrhizi genes were investigated for their feasibility to suppress ASR through a bean pod mottle virus (BPMV)‐based...

Wei Wang, Jie Wang, Francis M. P. Choi, Ping Ding, more

Global Ecology and Biogeography > 29 > 2 > 220 - 231

Aim Rapid anthropogenic warming coupled with changes in land use is altering the distributions of species, with consequences for ecosystem functioning and services. It is crucial to evaluate species range shifts based on understanding of the interaction of temperature with non‐climatic factors such as habitat availability and dispersal potential. Here, we aim to investigate roles of environmental...

The AVR4 effector is involved in cercosporin biosynthesis and likely affects the virulence of Cercospora cf. flagellaris on soybean

Josielle Santos Rezende, Marija Zivanovic, Maria Izabel Costa de Novaes, Zhi‐Yuan Chen

Molecular Plant Pathology > 21 > 1 > 53 - 65

One of the most devastating fungal diseases of soybean in the southern USA is Cercospora leaf blight (CLB), which is caused mainly by Cercospora cf. flagellaris. Recent studies found that the fungal effector AVR4, originally identified in Cladosporium fulvum as a chitin‐binding protein, is highly conserved among other Cercospora species. We wanted to determine whether it is present in C. cf. flagellaris...

HIsarna is a promising ironmaking technology to reduce CO₂ emission. Information of phase transformation is essential for reaction analysis of the cyclone reactor of the HIsarna process. In addition, data of density and volume of the ore particles are necessary for estimation of the residence time of the particles in the cyclone reactor. Phase transformation of iron ore particles was experimentally...

One-pot synthesis of highly conductive nickel-rich phosphide/CNTs hybrid as a polar sulfur host for high-rate and long-cycle Li-S battery

Xiao-Fei Yu, Dong-Xu Tian, Wen-Cui Li, Bin He, more

Nano Research > 2019 > 12 > 5 > 1193-1197

Lithium sulfur battery has been identified as a promising candidate for next storage devices attributing to ultrahigh energy density. However, non-conductive nature of sulfur and shuttling effect of soluble lithium polysulfides are intractable remaining problems. Herein, we develop a highly conductive nickel-rich Ni₁₂P₅/CNTs hybrid with high specific surface area as sulfur host to address these issues...

Carbon deposition in porous nickel/yttria-stabilized zirconia anode under methane atmosphere

Zhi-yuan Chen, Li-jun Wang, Xiao-jia Du, Zai-hong Sun, more

International Journal of Minerals, Metallurgy, and Materials > 2019 > 26 > 3 > 350-359

A commercial solid oxide fuel cell with a Ni/YSZ anode was characterized under a pure methane atmosphere. The amount of deposited carbon increased with an increase in temperature but decreased when the temperature exceeded 700°C. The reactivity of carbon decreased with increasing deposition temperature. Filamentous carbon was deposited from 400 to 600°C, whereas flake carbon was deposited at 700 and...

Oxidation resistance, thermal expansion and area specific resistance of Fe-Cr alloy interconnector for solid oxide fuel cell

Liu-zhen Bian, Zhi-yuan Chen, Li-jun Wang, Fu-shen Li, more

Journal of Iron and Steel Research, International > 2017 > 24 > 1 > 77-83

It is promising for metal especially ferritic stainless steel (FSS) to be used as interconnector when the solid oxide fuel cell (SOFC) is operated at temperature lower than 800 °C. However, there are many challenges for FSS such as anti-oxidant, poisoning to cathode and high area specific resistance (ASR) when using as SOFC interconnector. The effect of Cr content (12 — 30 mass%) in Fe-Cr alloys on...
