TL;DR: In this paper, anodic properties of La1−xSrxMnO3 electrodes were investigated in alkaline solutions and it was found that the catalytic activity for the oxygen evolution reaction was relatively high and increased with the increase of x in La 1−x SrxMmO3.

TL;DR: In this paper, the dependence of the spectral behavior and conversion efficiencies of rare-earth plasma extreme ultraviolet sources with peak emission at 6.7 nm on laser wavelength and the initial target density was investigated.
Abstract: We have investigated the dependence of the spectral behavior and conversion efficiencies of rare-earth plasma extreme ultraviolet sources with peak emission at 6.7 nm on laser wavelength and the initial target density. The maximum conversion efficiency was 1.3% at a laser intensity of 1.6×1012 W/cm2 at an operating wavelength of 1064 nm, when self-absorption was reduced by use of a low initial density target. Moreover, the lower-density results in a narrower spectrum and therefore improved spectral purity. It is shown to be important to use a low initial density target and/or to produce low electron density plasmas for efficient extreme ultraviolet sources when using high-Z targets.

TL;DR: Comparison of amino acid sequences on ORF1a encoding polyproteins, the most variable region, reflects the CTV isolate relationship ; NUagA is closely related to VT, SY568, and T385, but distantly related to T36.
Abstract: The complete nucleotide sequence of a seedling-yellows-inducing isolate NUagA of Citrus tristeza virus (CTV) was determined. It consisted of 19302 nucleotides and contained 12 open reading frames (ORF) organized identically to those of previously sequenced isolates. This genome is the largest among the CTV genome sequenced so far ; it is 6 nucleotides (nt), 76 nt, 43 nt, and 53 nt longer than that of T36 (quick decline, Florida), VT (seedling yellows, Israel), T385 (mild, Spain), and SY568 (stem pitting, California), respectively. Sequence comparison of NUagA and the other isolates revealed approximately 90% identities throughout the 3′ half of the genome. The 5′ half of the genome was only about 70% identical to that of T36 but still high at about 90% to those of VT, SY568, and T385. Comparison of amino acid sequences on ORF1a encoding polyproteins, the most variable region, reflects the CTV isolate relationship ; NUagA is closely related to VT, SY568, and T385, but distantly related to T36.

TL;DR: The present study demonstrates that TRH plays an important role in both GH and PRL synthesis and release and is the first report in which the effects of cyclo(His-Pro) on GH synthesis in teleosts are demonstrated.

TL;DR: In this paper, a novel lensed fiber employing a wedge-shaped graded-index fiber (GIF) was proposed and the characteristic of coupling loss as a function of the aspect ratio was numerically investigated.
Abstract: A novel lensed fiber employing a wedge-shaped graded-index fiber (GIF) is proposed. The characteristic of coupling loss as a function of the aspect ratio is numerically investigated. When the aspect ratio is seven, the coupling loss of a wedge-shaped GIF and a conventional wedge-shaped SMF are 0.22 dB and 0.60 dB, respectively, and when the aspect ratio is 13, they are 0.5 dB and 2.4 dB. The tolerance to laser diode (LD)-fiber displacement is also numerically investigated, and it is confirmed that the proposed fiber has larger tolerance than a conventional wedge-shaped single-mode fiber (SMF). The performance of the new lensed fiber is also experimentally verified.
