A Morphological Study of the Supernova Remnant RX J0852.0-4622
No full textWe conduct a multiwavelength morphological study of the Galactic supernova remnant (SNR) RX J0852.0–4622 (also known as Vela Jr., Vela Z, and G266.2−1.2). RX J0852.0–4622 is coincident with the edge of the larger Vela SNR causing confusion in the attribution of some filamentary structures to either RX J0852.0–4622 or its larger sibling. We find that the RX J0852.0–4622 radio-continuum emission can be characterized by a two-dimensional shell with a radius of 0°.90 ± 0°.01 (or 11.8 ± 0.6 pc at an assumed distance of 750 pc) centered at (l, b) = (133°. 08 ± 0°.01,−46°. 34 ± 0°.01) (or R.A. = 8h 52m19 2, decl. = −46°20′24 0, J2000), consistent with X-ray and gamma-ray emission. Although [O III] emission features are generally associated with the Vela SNR, one particular [O III] emission feature, which we denote as “the Vela Claw,” morphologically matches a molecular clump that is thought to have been stripped by the stellar progenitor of the RX J0852.0–4622 SNR. We argue that the Vela Claw feature is possibly associated with RX J0852.0–4622. Toward the northwestern edge of RX J0852.0–4622 , we find a flattening of the radio spectral index toward another molecular clump also thought to be associated with RX J0852.0–4622 . It is currently unclear whether this feature and the Vela Claw result from interactions between the RX J0852.0–4622 shock and interstellar medium gas
Conformation transition kinetics of regenerated Bombyx mori silk fibroin membrane monitored by time-resolved FTIR spectroscopy
No full textThe ethanol-induced conformation transition of regenerated B. mori silk fibroin membrane from a poorly defined to the well ordered state was monitored by time-resolved Fourier transform infrared spectroscopy (FTIR) for the first time. From the analysis of FTIR difference spectra, taken on time scales as short as 6 seconds and up to one h after addition of ethanol, intensity vs. time plots of an increasing band at 1618/cm were observed indicating formation of a beta -sheet coincident with the loss of intensity of a band at 1668/cm indicating decreases of random coil and/or silk I structure. Both infrared markers were fitted with identical biphasic exponential decay functions, however, there was a clear burst phase occurring prior to the onset of the observed transitions. The conformation transition process is indicated to either proceed sequentially through (at least) two intermediate states that contain different levels of beta -sheet structure or to have parallel pathways of initial beta -sheet formation followed by a slower perfection phase. The first observed process forms in a burst phase a few seconds after mixing (or even faster), prior to the collection of the first spectrum at 6 seconds. The second observed process occurs with a time constant of ~0.5 minutes, the intermediate present at this stage then continues with a time constant of 5.5 minutes completing the observed formation of the beta -sheet. The conformation transition of this slower intermediate is not only indicated by an analysis of the kinetics of the random coil and beta -sheet-specific bands discussed above, it roughly coincides with the appearance of an additional infrared marker at 1695/cm, which may be a marker for beta -sheet structure specific to the formation of the perfected structure. The conformation transition of this protein analysed by infrared spectroscopy provides insight into a part of the fascinating process of cocoon formation in B. mori..RE: 43 ref.; RN: 64-17-5; SC: 0E; CA; PE; XURL: DOI; DIGITAL-OBJECT-IDENTIFIERSource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=doi%3a10.1016%2fS0301-4622%2800%2900213-1&issn=0301-4622&isbn=&volume=89&issue=1&spage=25&pages=25-34&date=2001&title=Biophysical%20Chemistry&atitle=Conformation%20transition%20kinetics%20of%20regenerated%20Bombyx%20mori%20silk%20fibroin%20membrane%20monitored%20by%20time-resolved%20FTIR%20spectroscopy.&aulast=%20Marinkovic&pid=%3Cauthor%3EChen%20Xin%3bShao%20ZhengZhong%3bMarinkovic%2c%20N%20S%3bMiller%2c%20L%20M%3bZhou%20Ping%3bChance%2c%20M%20R%3C%2Fauthor%3E%3CAN%3E20013152002%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
