A Search for Extraterrestrial Technosignatures in Archival FAST Survey Data Using a New Procedure

The "search for extraterrestrial intelligence" (SETI) commensal surveys aim to scan the sky to find possible technosignatures from the extraterrestrial intelligence (ETI). The mitigation of radio frequency interference (RFI) is an important step, especially for the most sensitive Five-hundred-meter Aperture Spherical radio Telescope (FAST), which can detect more weak RFI. In this paper, we propose several new techniques for RFI mitigation, and use our procedure to search for ETI signals from the archival data of FAST's first SETI commensal survey. We detect the persistent narrowband RFI by setting a threshold of the signals' sky separation, and detect the drifting RFI (and potentially other types of RFI) using the Hough transform. We also use the clustering algorithms to remove more RFI and select candidates. The results of our procedure are compared to the earlier work on the same FAST data. We find that our methods, though relatively simpler in computation, remove more RFI (99.9912% compared to 99.9063% in the earlier work), but preserve the simulated ETI signals except those (5.1%) severely affected by the RFI. We also report more interesting candidate signals, about a dozen of which are new candidates that are not previously reported. In addition, we find that the proposed Hough transform method, with suitable parameters, also has the potential to remove the broadband RFI. We conclude that our methods can effectively remove the vast majority of the RFI while preserving and finding the candidate signals that we are interested in.Comment: 14 pages, 10 figures.

A new species of stream-living toad (Anura: Bufonidae: Bufo) from Guangdong, China

Abstract In this work, we describe a new species of genus Bufo, Bufo exiguus sp. nov. from Mt. Nankun, Guangdong Province, China. This new species can be distinguished from all congeners by significant divergences in the mitochondrial 16S rRNA and CO1 genes and by a combination of morphological characters: small body size, tympanum absent, parotoid glands small and olive-shaped, tarsal fold absent, dorsal body with a fine vertebral line and white nuptial spinules present on dorsal and inner surfaces of fingers I and II in males. At present, Bufo exiguus sp. nov. is only known from the slow-flowing montane streams from its type locality and its conservation status should be carefully addressed

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

A Numerical Study on the Correlation between Sky View Factor and Summer Microclimate of Local Climate Zones

In the context of urbanization, research on urban microclimate and thermal comfort has become one of the themes of eco-city design. Sky view factor (SVF), one of the parameters of urban spatial form, combines multiple morphological information, such as plane opening, aspect ratio, and building density and has an important impact on the urban microclimate. However, there is still no clear research conclusion on the correlation between SVF and microclimate. In this paper, nine Local Climate Zone (LCZ) models are used and typical summer meteorological conditions of Nanjing are applied as an attempt to partially fill this gap. The calculated microclimate and thermal comfort indices include air temperature (AT), surface temperature (ST), relative humidity (RH), wind speed (WS), mean radiant temperature (MRT), and predicted mean vote (PMV). Results show that the local effect of urban morphology on thermal comfort can be retrieved from the use of comprehensive parameters such as SVF (which takes into account the building height, layout, and density) whose distribution in the investigated models showed to be correlated with MRT, so did PMV under low wind speed conditions

Systematic revision of Stegodera Martens, 1876 (Gastropoda, Stylommatophora, Camaenidae), with description of a new genus

The monotypic genus Stegodera Martens, 1876 is systematically revised based on anatomical and morphological examination of freshly collected specimens. A new species from southern Hunan, which resembles Stegodera angusticollis, is confirmed to represent a new genus evidenced by comparative shell morphology and anatomy as well as by molecular phylogenetic analyses. The new genus might be more closely related to Stegodera and Nesiohelix Kuroda & Emura, but differs anatomically from the latter two genera by the absence of a dart apparatus

TYPE LOCALITY. — China, Sichuan, Chengdu Shi, Dujiangyan Shi, Qingcheng Houshan, 1200 m a.s.l. DIAGNOSIS. — A Coccoglypta species with a rounded body whorl, greenish to yellowish colour and weak sculpture on the ventral shell surface. DESCRIPTION Shell dextral, rather large, light brown (dorsal surface) to greenish or yellowish (ventral surface, and dorsal side behind the aperture); colour changing below keel, and some light colouration indicating some growth lines; shell depressed globular, body whorl rounded or with very slightly marked keel (if present, mostly visible from ventral view of the body whorl); entire shell consisting of 5.25-5.75 whorls, separated by rather shallow suture, sometimes indicated by a whitish line; protoconch consisting of 1.5-1.75 whorls, matt, rather smooth, dorsal side of teleoconch dominated by irregular, rather rough wrinkles and tubercles (tubercles appearing after the first 1.5 whorls of teleoconch); some fine spiral grooves also visible; ventral surface without or with much less prominent tubercles, rather “hammered”, irregularly wrinkled and spirally grooved; aperture strongly oblique to shell axis, white; peristome expanded (mostly in basal and umbilical direction) but not reflected; parietal callus weak, only indicated by fine whitish calcareous layer, which is transparent in fresh shells; umbilicus open, moderately wide, showing all whorls. Measurements D = 29.1-32.9 mm, H = 16.1-20.6 mm (n = 3). Remarks on the genitalia From a single specimen anatomically examined from Qingcheng Houshan (Figs 3-4). Right ommatophoral retractor crossed vagina and penis. Inner wall of the penis finely reticulated (Fig. 4A), produced by the perpendicular projections of the slender longitudinal folds. Inner wall of vagina with widelyspaced, sometimes converging longitudinal folds (Fig. 4B). DIFFERENTIAL DIAGNOSIS. — Coccoglypta liui Páll-Gergely, n. sp. differs from C. pinchoniana, which also occurs sympatrically, by the usually narrower umbilicus, weaker sculpture of the ventral surface, the lighter colour, and the less keeled body whorl. The ventral side of C. pinchoniana is dominated by ribs and tubercles, but also has fine spiral grooves. However, the ventral shell surface of Coccoglypta liui Páll-Gergely, n. sp. has much less prominent tubercles and is dominated by spiral grooves. DISTRIBUTION. — So far this species is known only from Qingcheng Houshan and Qingcheng Shan in Sichuan Province, China (Fig. 5). REMARKS Our observations on the genitalia generally match with those of Schileyko (2004), based on a C. pinchoniana specimen collected in Emei Shan. The notable differences are the following: 1) the mucus glands form a single oval mass, not separated clearly as on Schileyko’s (2004) drawing; 2) we have not found a twisted part of the spermathecal stalk in a capsule; and 3) the bursa copulatrix is smaller and more elongated than the specimen examined by Schileyko (2004). It is yet unclear which of these differences represents speciesspecific traits.Published as part of Páll-Gergely, Barna, Hunyadi, András, Chen, Zhe-Yu & Lyu, Zhi-Tong, 2019, A review of the genus Coccoglypta Pilsbry, 1895 (Gastropoda: Pulmonata: Camaenidae), pp. 595-608 in Zoosystema 41 (29) on pages 598-601, DOI: 10.5252/zoosystema2019v41a29, http://zenodo.org/record/372611
