Gui-Sun Moon, Sun-Woong Kim, Jeong-Ah Shin, Hae-Kyung Wee, Jong Un Park, Myung-Kwan Park, and Wonil Chung. 2018. Voice Mismatch Meets Neurolinguistics. Studies in Modern Grammar 99, 85-115. This paper aims to investigate Korean advanced L2 English learners’ strategies for ellipsis resolution during sentence processing. Ellipsis resolution is known to involve several stages of information processing from the initial step of detecting an ellipsis-licensing element by the parser to the final stage of integrating the ellipsis site with the information retrieved from the antecedent of the ellipsis site. In examining these steps, we have manipulated three factors: (i) TP vs. VP-ellipsis; (ii) two types of discourse coherence relations (resemblance(-contrast) vs. cause-effect relations); (iii) voice match vs. mismatch. We found through the ERP recordings that voice mismatch in TP ellipsis elicited N400, followed by P600, irrespective of discourse coherence relations. In contrast, voice mismatch in VP-ellipsis registered N400 only in resemblance(-contrast) relation, but not in cause-effect relation. These findings lead us to conclude that Korean advanced L2 learners of English seem to undergo the full sequence of processing stages required for ellipsis resolution.

In the process of ingot pulling of the Si single crystal, the pulling velocity of the single crystal silicon should be faster than the dislocation propagation velocity in order to have uniform resistivity in (100) plane. The (100) plane has no dislocation when single crystal seed is contacted and seperated from the melt. Oxygen content of the Si ingot should be controlled by melting Si in Ar gas atmosphere with magnetic field to increase the viscosity of the melt. The efficiency of the Si wafer solar cell can be enhanced by (1) removing the defects in the Si wafer, (2) minimizing the recombination and thermalization of the atoms which lead to energy loss, (3) forming pyramid structure on the cell surface to reduce reflection of the light. The shading of the cell can be minimized via controlling of the finger width of the solar cell. the atoms which lead to energy loss, (3) forming pyramid structure on the cell surface to reduce reflection of the light.

Rhabditis blumi, isolated from Exomala orientalis, is a necromenic type of nematode that possesses several attributes of a potential biological control agent such as ease in culture conditions, high rates of reproduction and virulence, short life cycle and rapid multiplication etc. Pathogenicity of R. blumi was tested against 5 coleopteran species and 5 lepidopteran species. All insect larvae were susceptible to R. blumi, showing over 60% mortality except for Holotrichia kiotoensis and Ectinohoplia rufipes. The highest mortality was observed in Plutella xylostella (88%), followed by Artogeia rapae, Exomala orientalis, Spodoptera litura and Anomala rufocuprea (over 70%). Reproductive capacity of R. blumi differed from each insect species, ranging from 17 to 656 dauer juveniles/mg of insect larva. Dauer juvenile production was most in Plutella xylostella larvae, producing 656 dauer juveniles/mg of host body weight, followed by E. orientalis, H. kiotoensis, and A. rapae larvae (over 100 dauer juvenile per mg).

A series of PP-g-AAc-AAm of different charge levels were prepared as the polymeric charge carrier, and the adhesion of PMNs to the prepared surface as well as the effects of serum proteins on PMNs adhesion were studied systematically. The samples enhanced PMNs adhesion in the order of PP-g-AAc1-AAm4, PP-g-AAc2-AAm3, PP-g-AAc3-AAm2, and PP-g-AAc4-AAm1, eg., PMNs adhesion increased with increase in the positive charge of the substrates. From this, the charge interaction between the PMNs and the substrates seems to be the dominantfactor in the PMNs adhesion. However, the results from SDS-PAGE and the immuno-blotting showed that the adsorption of proteins, especially immune proteins, also increasedwith increase in the positive charge of the samples. In addition, PMNs adhered to the samples show the spreading behavior which is uncommon phenomenon for the cells tightly adhered by strong charge interaction. Therefore, it is concluded that the immune proteins bound to the samples enhances PMNs adhesion by increasing PMNs chemotaxis.

Biological control has been tried for integrated pest management. It is often comparable, safe, and environment-friendly, making itself an alternative for chemical agents. Filamentous microorganisms, i.e., fungi and streptomystes, produce many kinds of useful metabolites, and some of them have been developed as a biocontrol agent. However, they still have a long way because of the concern of manufacturing cost. Therefore, process development was intensively studied to meet cost-effectiveness. Operating conditions of bioreactor, e.g., agitation and aeration, had an effect on biological and physiological responses such as mycelial morphology, oxygen and nutrient transfer. Understanding relationship between operating parameters and microbial responses in terms of growth, substrate and oxygen consumption, and production yield was critical for process development. This study dedicated to build strategies for mass production of biological control agent using aerobic filamentous microorganisms.

<P>In this study, V-doped NiO materials were prepared by simple coprecipitation and thermal decomposition, and the effect of the vanadium content on the morphology, structural properties, electrochemical behavior, and cycling stability of NiO upon oxidation and reduction was analyzed for supercapacitor applications. The results show an improvement in the capacitive characteristics of the V-doped NiO, including increases in the specific capacitance after the addition of just 1.0, 2.0, and 4.0 at% V. All V<SUB><I>x</I></SUB>Ni<SUB>1−<I>x</I></SUB>O electrodes (<I>x</I> = 0.01, 0.02, 0.04) exhibited higher specific capacitances of 371.2, 365.7, and 386.2 F g<SUP>−1</SUP> than that of pure NiO (303.2 F g<SUP>−1</SUP>) at a current density of 2 A g<SUP>−1</SUP> after 500 cycles, respectively. The V<SUB>0.01</SUB>Ni<SUB>0.99</SUB>O electrode showed good capacitance retention of 73.5% at a current density of 2 A g<SUP>−1</SUP> for more than 500 cycles in a cycling test. Importantly, the rate capability of the V<SUB>0.01</SUB>Ni<SUB>0.99</SUB>O electrode was maintained at about 84.7% as discharge current density was increased from 0.5 A g<SUP>−1</SUP> to 4 A g<SUP>−1</SUP>.</P> <P>Graphic Abstract</P><P>The V-doped NiO electrode materials were synthesized by simple co-precipitation and thermal decomposition. By modifying and optimizing the electrode materials, a 1.0 at% V-doped NiO electrode showed enhanced electrochemical performance due to its unique cross-linked porous nanostructure. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c3cp52498a'> </P>

Lignin-derived porous carbon has been identified as a versatile electrode material for supercapacitors (SCs) in energy storage systems (ESSs) owing to their intrinsic advantages including good electrical conductivity, low cost, high thermal and chemical stability, and high porosity, which stem from high surface, appropriate pore distribution, tailored morphologies, heterostructures, and diverse derivates. In this review, to provide a fundamental understanding of the properties of lignin, we first summarize the origin, historical development, and basic physicochemical properties. Next, we describe essential strategies for the preparation of lignin-derived porous carbon electrode materials and then highlight the latest advances in the utilization of lignin-derived porous carbon materials as advanced electrode materials. Finally, we provide some of our own insights into the major challenges and prospective research directions of lignin-derived porous carbon materials for supercapacitors. We believe that this review will provide general guidance for the design of next-generation electrode materials for supercapacitors.
