Phylogenetic relationships and estimation of divergence times among Sisoridae catfishes
No full textNineteen taxa representing 10 genera of Sisoridae were subjected to phylogenetic analyses of sequence data for the nuclear genes Plagl2 and ADNP and the mitochondrial gene cytochrome . The three data sets were analyzed separately and combined into a single data set to reconstruct phylogenetic relationships among Chinese sisorids. Both Chinese Sisoridae as a whole and the glyptosternoid taxa formed monophyletic groups. The genus is likely to be the earliest diverging extant genus among the Chinese Sisoridae. The four species included in the study formed a monophyletic group. was indicated to be earliest diverging glyptosternoid, followed by and . Our data supported the conclusion that and both formed a monophyletic group. On the basis of the fossil record and the results of a molecular dating analysis, we estimated that the Sisoridae diverged in the late Miocene about 12.2 Mya. The glyptosternoid clade was indicated to have diverged, also in the late Miocene, about 10.7 Mya, and the more specialized glyptosternoid genera, such as , originated in the Pleistocene (within 1.9 Mya). The speciation of glyptosternoid fishes is hypothesized to be closely related with the uplift of the Qinghai-Tibet Plateau.Nineteen taxa representing 10 genera of Sisoridae were subjected to phylogenetic analyses of sequence data for the nuclear genes Plagl2 and ADNP and the mitochondrial gene cytochrome .

HiPRIME: Hierarchical and Passivity Preserved Interconnect Macromodeling Engine for RLKC Power Delivery
No full textThis paper proposes a general hierarchical analysis
methodology, HiPRIME, to efficiently analyze RLKC power delivery
systems. After partitioning the circuits into blocks, we develop
and apply the IEKS (Improved Extended Krylov Subspace)
method to build the multiport Norton equivalent circuits which
transform all the internal sources to Norton current sources at
ports. Since there are no active elements inside the Norton circuits,
passive or realizable model order reduction techniques such
as PRIMA can be applied. The significant speed improvement, 700
times faster than Spice with less than 0.2% error and 7 times faster
than a state-of-the-art solver, InductWise, is observed. To further
reduce the top-level hierarchy runtime, we develop a second-level
model reduction algorithm and prove its passivity

Argon Isotopic Dating of Neolithic Jade Artifacts and Raw Materials from Eastern China and Its Implications
No full textThe origin of Chinese culture during the Neolithic age has long been a focus of academic debate. The controversy is centered on whether the origins of Neolithic culture in China were singular or more di verse. Con se quently, understanding the spatial distribution of archaeological jade artifacts in the context of the sources of raw jade has been one of the most reason ablemeans to infer the routes of cultural migration and trade activities during the Neo lithic period. It was widely advocated that HeTian Jade from XinJiang was the sole source of jade for all of Neo lithic China. However, the discovery of jade mines at MeiLing (JiangSu Prov ince) in 1989 raises the question as to whether raw jade could have come from an alternate source other than XinJiang during this period. Using 40Ar/39Ar laser dating technique, this study at tempts to correlate the formation ages of excavated jade artifacts at LingJiaTan (AnHui Prov ince) to the nearby MeiLing jade mines and far away HeTian jade mines, in the hope of trac ing the pos si ble cul ture in ter ac tions and trad ing ac tiv i ties among these ar eas. The re sults show that the for ma tion ages of LingJiaTan jade ar ti facts are around 120 Ma, about the same age as jade from the nearby MeiLing jade mines. In addition, both jades are tremolite with similar chemical compositions and mineral characteristics. There fore, the material source of jade artifacts ex cavated at LingJiaTan archeological site most likely originated from these nearby MeiLing jade mines. By contrast, there is a big difference in the formation ages between Meiling jade artifacts and raw HeTian Jade (277.3 Ma). Based on these results, weconclude that in the Neo lithic age, people living in LingJiaTan (AnHui Province) probably had interactions with people around MeiLing (JiangSu Province), but not with peoples of XinJiang Province
Threshold automatic selection hybrid phase unwrapping algorithm for digital holographic microscopy
No full textConventional quality-guided (QG) phase unwrapping algorithm is hard to be applied to digital holographic microscopy because of the long execution time. In this paper, we present a threshold automatic selection hybrid phase unwrapping algorithm that combines the existing QG algorithm and the flood-filled (FF) algorithm to solve this problem. The original wrapped phase map is divided into high- and low-quality sub-maps by selecting a threshold automatically, and then the FF and QG unwrapping algorithms are used in each level to unwrap the phase, respectively. The feasibility of the proposed method is proved by experimental results, and the execution speed is shown to be much faster than that of the original QG unwrapping algorithm.

Notes Of the original type material, only four unlabeled females were found that resemble the original description and illustration provided for A. meilingensis. One complete female is here interpreted as holotype of the species. A second female lacks the funicle and clava of both antennae, and left front leg and right metatarsi. The third female lacks the right protarsi, and the fourth female lacks its left antenna, right funicle and clava, and right mesotarsus. Remarks Females of this species resemble those of A. huangi, but are differentiated by the following characters: fore wing much shorter, extending only slightly over middle of Mt2 compared to middle of gaster for A. huangi (cf. Figs 32, 34); fore wing disc with apical one-third densely setose with yellowish-brown setae, without hyaline cross-band compared to fore wing disc of A. huangi with thinner brownish setae, and has a tapered hyaline cross-band behind marginal vein; anterior convex medial lobe rhomboidal compared to triangular for A. huangi with (cf. Figs 31, 38); hind leg with basitarsus as long as following three tarsomeres compared to following four tarsomeres in A. huangi (cf. Figs 33, 36). In the key of Kalina (1981), A. meilingensis keys out to A. gastropachae, which is a brachypterous form of A. bifasciatus (Geoffroy, 1785) based on the rearings and synonym of Ishii (1938). The original description of A. gastropachae (Ashmead 1904) states that the fore wings are “fuscous, with a transverse band at base and [within] apical third hyaline”, whereas A. meilingensis has the basal two-thirds hyaline and the apical one-third with yellowish-brown setae, which is similar to the fore wing color pattern of A. meilingensis females. Females of A. gastropachae determined in 2015 by L. Fusu in the Canadian National Collection of Insects, Arachnids & Nematodes (Ottawa) were examined by the senior author. Females have the medial lobe of mesoscutum triangular, the gaster longer than the mesosoma, and the scrobal depression distinctly delimited dorsally compared to A. gastropachae.Published as part of Peng, Lingfei, Tang, Lu & Gibson, Gary A.
