V. 2019, Coll. A. Li & Y. F. Hsu (IOZ). Paratypes. 2♂ 6♀, same locality as for holotype, reared from Cyclocarya paliurus, emgd. 9. V/ 12. VI. 2019, Coll. A. Li & Y. F. Hsu; 2♂ 1♀, VII. 26. 2018, Coll. Y. F. Hsu, 7♂ 7♀, 3–31. VIII. 2018, Coll. A. Li. (IOZ, FNNR, NTNU). Male (Figs. 1–2): FL 16.5–21.3 mm (mean 19.5± 1.2 mm, n=12); female (Figs. 3–4): FL: 17.5–21.3 (mean 19.9±1.0 mm, n=14). Diagnosis. The distinction between subspecies sichuanensis Hsu & Li, subsp. nov. and nominotypical A. panda is mainly on markings of wing undersides: 1) M1 and M2 spots of the distal band of central symmetry system on forewing underside are detached from R5 spot in the nominotypical subspecies, whereas they are conjoined with R5 spot in ssp. sichuanensis; 2) proximal band of central symmetry system is large, with width much broader than cell bar in the nominotypical subspecies, whereas that is small, narrower or as wide as cell bar in ssp. sichuanensis; 3) three spots of the proximal band of central symmetry system near wing base on hindwing underside are conjoined into a bar in the nominotypical subspecies, whereas they are separated, notably the posterior spot, in ssp. sichuanensis; 4) ground color of wing undersides is overlaid with prominent gray scalings in ssp. sichuanensis, whereas it is paler with gray scalings poorly developed in the nominotypical subspecies. Ssp. yunnanensis is different from ssp. sichuanensis and the nominotypical subspecies by the greatly reduced proximal band of central symmetry system on forewing underside. Hostplant. Cyclocarya paliurus (Juglandaceae). Bionomics. Adults were observed staying on foliage of the hostplants, descending to understory vegetation when sunshine was intensive with high temperature in fair weather. Ova (Figs. 5–6) were mostly found on naked leaflet in dormancy, but occasionally on small twig. Green larva (Fig. 7) devours young tissue of the hostplant such as new buds and soft leaves. Brown pupa (Fig. 8) is girdled. Distribution. Araragi panda sichuanensis Hsu & Li, subsp. nov. has been so far found in a few canyons in Baoxing area in Sichuan Province, belonging to north-south oriented Qionglai Mountain Range. This mountain range is approximately 400 kilometers distant from east-west oriented Qingling Mountain Range in Gansu and Shaanxi Province, where the nominotypical subspecies of A. panda inhabits.Published as part of Hsu, Yu-Feng & Li, Ai-Min, 2019, A new subspecies of Araragi panda Hsu & Chou (Lepidoptera, Lycaenidae, Theclini) from Sichuan, western China, pp. 296-300 in Zootaxa 4701 (3) on pages 297-298, DOI: 10.11646/zootaxa.4701.3.6, http://zenodo.org/record/355806

No full textComputing resources sensitive parallelization of neural neworks for large scale diabetes data modelling, diagnosis and prediction
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Diabetes has become one of the most severe deceases due to an increasing number of diabetes patients globally. A large amount of digital data on diabetes has been collected through various channels. How to utilize these data sets to help doctors to make a decision on diagnosis, treatment and prediction of diabetic patients poses many challenges to the research community. The thesis investigates mathematical models with a focus on neural networks for large scale diabetes data modelling and analysis by utilizing modern computing technologies such as grid computing and cloud computing. These computing technologies provide users with an inexpensive way to have access to extensive computing resources over the Internet for solving data and computationally intensive problems. This thesis evaluates the performance of seven representative machine learning techniques in classification of diabetes data and the results show that neural network produces the best accuracy in classification but incurs high overhead in data training. As a result, the thesis develops MRNN, a parallel neural network model based on the MapReduce programming model which has become an enabling technology in support of data intensive applications in the clouds.
By partitioning the diabetic data set into a number of equally sized data blocks, the workload in training is distributed among a number of computing nodes for speedup in data training. MRNN is first evaluated in small scale experimental environments using 12 mappers and subsequently is evaluated in large scale simulated environments using up to 1000 mappers. Both the experimental and simulations results have shown the effectiveness of MRNN in classification, and its high scalability in data training.
MapReduce does not have a sophisticated job scheduling scheme for heterogonous computing environments in which the computing nodes may have varied computing capabilities. For this purpose, this thesis develops a load balancing scheme based on genetic algorithms with an aim to balance the training workload among heterogeneous computing nodes. The nodes with more computing capacities will receive more MapReduce jobs for execution. Divisible load theory is employed to guide the evolutionary process of the genetic algorithm with an aim to achieve fast convergence. The proposed load balancing scheme is evaluated in large scale simulated MapReduce environments with varied levels of heterogeneity using different sizes of data sets. All the results show that the genetic algorithm based load balancing scheme significantly reduce the makespan in job execution in comparison with the time consumed without load balancing.This work is funded by the EPSRC and China Market Association

(mis-identification) Aphnaeus syama formosana; Seitz 1927 (not Matsumura): the Macrolepidoptera of the world: 937, pl. 156, fig. 156h; Hirayama (not Moore) 1933: Butterflies in Colour: pl. 20, Fig. 3; pl. 21, fig. 3. (mis-identification) Aphnaeus syama formosana ab. nakaharai Naritomi 1941: Kontyukai 91: 618, pl. 4, Fig. 4. Diagnosis. Ssp. lamuae is characteristic by distal band of central symmetry system of hindwing undersides broken posteriorly at 1A+2A (Figs. 10, 12, 14, 16), whereas this band is continuous, forming a complete V-shaped band in the other subspecies (Figs. 18, 20). The appearance of ssp. lamuae is most similar to ssp. sepulveda Fruhstorfer, 1912 of continental China (Figs. 17–20, 30–34) in wing patterns, sharing the feature of distal band of central symmetry system of forewing undersides in touch with parafocal elements. Ssp. lamuae demonstrates profound seasonal variation, with the markings on wing undersides of individuals emerged in dry/cooler months reduced and turning reddish (Figs. 12, 16). By contrast, seasonal variation is absent in ssp. sepulveda, with individuals emerged from all seasons possessing black spots and bands (Figs. 18, 20); posterior margin of costa on valva is smooth in lamuae (Fig. 27), whereas it is unevenly serrate in ssp. sepulveda (Fig. 32).

Paratypes deposited in NHM, NMNS, and NTNU. Bionomics. Female butterfly oviposits on foliage (twig or leaf) of hostplant (Fig. 43, 44) in the presence of associated ants. Larvae are phytophagous but tended by Crematogaster ants on regular basis (Lin 2011). The larvae devour leaves by scratching epidermis and mesophyll. Larvae conceal themselves gregariously in shelters construct- ed by tying dry leaves while not feeding (Figs. 45). Pupation is taken place within the larval shelters (Figs. 46). Hostplants. Plants oviposited by females or utilized by immatures in the wild included Maesa japonica (Primulaceae) (04F53, oviposition), Ardisia crenata (Primulaceae) (09C26, 09J46, larvae), A. cornudentata morrisonensis (Primulaceae) (09H10, oviposition; 10H20, larvae), A. cornudentata cornudentata (Primulaceae) (09K4, 10H27, 10J52, 11D33, larvae), Mallotus japonica (Euphorbiaceae) (10G26, larva) and Smilax odortissima (Smilaceae)(10J41, larvae). Myrmecophily. This butterfly is obligatorily associated with Crematogester amia (09C26, 09H10, 10G26, 10H20, 10J41) and C. popohana (09K4, 10H27, 10J52, 11D33) in the wild, but larvae may complete development without presence of ants in laboratory (Lin 2011). Etymology. The subspecific name lamuae refers to a comic character Lam (Lamu) created by a famous manga artist Rumiko Takahashi. The patterns of wing undersides recall the graphic design of the bikini Lam wears. Remarks. Seitz (1927) states that S. syama in Taiwan is diagnosable by having the ground color of wing undersides being white, but examined specimens and illustrations of literature all have yellow or creamy yellow ground color on wing undersides.Published as part of Hsu, Yu-Feng & Liang, Jia-Yuan, 2020, On systematic status of Spindasis syama Horsfield, [1829] in Taiwan and the Philippines (Lepidoptera: Lycaenidae: Aphnaeini), pp. 485-500 in Zootaxa 4763 (4) on pages 491-494, DOI: 10.11646/zootaxa.4763.4.2, http://zenodo.org/record/376205
