No full textHelvella cystidiata R.J. Xu, Q. Zhao & K.D. Hyde, sp. nov. FIGURE 3 Index Fungorum number: IF559702, Facesoffungi number: FoF 11345 Etymology. Cystidiata, named after the inflated ectal excipulum cells. Holotype: HKAS 78941 Pileus loosely saddle-shaped to irregularly lobed, 1–3 cm high, 1–4 cm broad, margin reflexed and fused with stipe, hymenium slightly wrinkled to rugose, greyish to greyish brown when fresh, becoming brown to blackish when dry, receptacle surface even, grey to greyish brown when fresh, becoming brownish when dry. Stipe 3–5 cm long, 0.5–1 cm broad, lacunose, with rounded-ribs, glabrous, greyish to greyish brown when fresh, becoming brownish when dry, with white mycelium at the base. Medullary excipulum 90–210 μm broad, of textura intricata, hyaline, composed of 3–4 μm broad hyphae, walls thickened, J- in Melzer’s reagent. Ectal excipulum 60–110 μm broad, of textura angularis, composed of 20–50 × 20–30 μm, subglobose to ellipsoid, inflated cells, hyaline, terminal cells 10–35 × 8–20 μm, blue in cotton blue, J-. Stipitipellis 45–70 μm, of textura angularis, hyaline, terminal cells 8–44 × 5–20 μm, blue in cotton blue, J-. Asci arising from croziers, 8-spored, subcylindrical to clavate, with apex rounded, 200–330 × 13–19 μm, J- in Melzer’s reagent, blue in cotton blue. Paraphyses filiform, 3–5 μm broad, slightly exceeding the asci, apex enlarged, 4–8 μm broad, hyaline, blue in cotton blue, J-. Ascospores [80/2/2, in H 2 O] 15–18.5 × 9–12 (–12.5) μm [Q = (1.33–1.83), Qm = (1.62 ± 0.86)], ellipsoid, smooth-walled under the light microscope, uniguttulate, with large central globose to broadly ellipsoidal oil droplet. Asexual morph: Undetermined. Habitat: Scattered or gregarious on the ground, under Pinus yunnanensis forests. Distribution: Currently only known in southwestern China. Specimen examined: CHINA, Yunnan Province, Gucheng County, on the ground, under Pinus yunnanensis Franch, alt. 2500 m, 16 Sep. 2012, Qi Zhao 1683 (HKAS 78941, holotype). CHINA, Yunnan Province, Lanping County, on the ground, alt. 2300 m, 16 Aug. 2011, Qi Zhao 1363 (HKAS 74316). Notes: Helvella cystidiata is characterized by its loosely saddle-shaped pileus with a margin reflexed and fused with stipe, a slightly wrinkled to rugose, greyish to grey-brown hymenium, an even, grey to greyish receptacle surface, a lacunose stipe with rounded-ribs, ectal excipulum comprised of ellipsoid to subglobose inflated cells and all tissues J- in Melzer’s reagent. Morphologically, Helvella cystidiata is similar to H. lacunosa, both sharing a margin flexed and fused with stipe of pileus and lacunose stipe, but the latter differs from the former as pubescent, yellowish brown to brownish when fresh. Ectal excipulum cells catenuliform in long fasciculate tufts (Afzelius 1783). Phylogenetically, Helvella cystidiata is allied with H. pseudolacunosa with strong statistical support (99% ML, 1.00 BYPP, FIGURE 1) and (97% ML, 1.00 BYPP, FIGURE 2). However, the latter species has a pinched hymenium, a creamy receptacle surface, and a lacunose stipe with an enlarged base (Ariyawansa et al. 2015).Published as part of Xu, Rong-Ju, Li, Lu & Zhao, Qi, 2022, Helvella cystidiata sp. nov.

Laskennallinen mallintaminen visuaalisen huomion analyysiin
No full textAbstractVisual scenes typically contain massive amounts of content that cannot be processed in a short time due to the limited processing capacity of the human visual system. The term, visual attention, is a biologically inspired and psychologically driven mechanism that works by selecting visually relevant information and filtering out the redundant contents.This thesis is a thorough summary of the main subjects around computational modeling for visual attention analysis, consisting of several published papers corresponding to my research progress. First, the data preparation for computational modeling will be introduced, including eye movement data, eye tracking data collection and eye tracking datasets facilitating the evaluation of computational modeling of visual attention. Second, computational models for visual attention analysis, or saliency models, are presented from traditional unsupervised methods to deep saliency models. Third, the subject about saliency integration will be illustrated that unifies multiple saliency maps from the multiple candidate saliency models for better accuracy.The contributions of this study are three folds. Firstly, we collect a task-driven eye tracking dataset for visual attention analysis. Secondly, we propose three saliency models for in-depth investigation in modeling visual attention, including an unsupervised model using the bi-directional propagation method, a Convolutional Neural Networks based model by connecting the Dense Conditional Random Fields for multi-scale saliency refinement, and a Convolutional Neural Networks based model with cascade Conditional Random Fields for joint model training. Thirdly, we propose a saliency integration method and conduct comprehensive experiments and analysis on the topic.Finally, we summarize the contributions of the work and propose the potential applications of saliency models and the extended saliency related topics to boost applications of saliency approaches on other computer vision topics.Original papersOriginal papers are not included in the electronic version of the dissertation.Xu, Y., Hong, X., He, Q., Zhao, G., & Pietikäinen, M.

Kuvat sisältävät tyypillisesti valtavan määrän informaatiota, jota ei pystytä prosessoimaan lyhyessä ajassa ihmisen näköjärjestelmän rajoitetun prosessointi kapasiteetin takia. Termi, visuaalinen huomio, on biologian ja psykologian motivoima mekanismi, joka toimii valiten oleellisen informaation ja suodattaen ylimääräisen informaation.
Mallintaaksemme huomio mekanismia konenäön käyttöön on olennaista, että laskennallinen malli visuaaliselle huomiolle ehdottaa tärkeät alueet kuvista, jotka ihmisen näköjärjestelmä on nähnyt.

Jianghuaimon Zhao & Xu & Huang 2022, gen. nov.
No full textGenus Jianghuaimon gen. nov. [Chinese name: ü淮ēøĸ] Type Species. Jianghuaimon dabiense gen. nov. et sp. nov., by present designation. Diagnosis. Small sized (CW <25 mm). Carapace subquadrate, flat, dorsal surface pitted (Fig. 1); epigastric cristae low; not confluent with postorbital cristae (Fig.1); external orbital angle bluntly triangular, almost straight (Fig. 1). Epistomial median lobe narrowly triangular (Fig. 2A). Maxilliped III with relatively broad ischium, exopod reaching beyond anterior edge of ischium, with long flagellum (Fig. 3A). Cheliped palm surface relatively rugose (Fig. 3F–G). Male anterior thoracic sternum wide, width 1.8 × length (Fig. 2B). Male pleon broadly triangular, tip of telson semicircular (Fig. 2C). G1 generally slender, pointing anterolaterally, terminal segment large and stout with wide opening at truncate tip, inner margin rounded (Fig. 3C–E, H–I). G2 with subquadrate basal segment (Fig. 3B). Female vulva ovate, large, located within sternite VI (Fig. 2F). Etymology. The genus name is an arbitrary combination of the zoogeographic location of the type locality, the Jianghuai freshwater zoogeographic dominion (Huang et al. 2020a), and the genus name, Potamon Savigny, 1816. Gender: neuter. Distribution. Huo Shan county, Lu’an city, Anhui province, China; Yingshan County, Huanggang City, Hubei Province, China. Remarks. Jianghuaimon gen. nov. has a rather unexceptional external appearance and most closely resembles Bottapotamon Türkay & Dai, 1997 and Neilupotamon Türkay & Dai, 1997 in its small size (CW <30 mm), relatively flat carapace with regions distinct, bluntly triangular external orbital angle and slightly unequal chelipeds. Jianghuaimon gen. nov. also resembles Huananpotamon Dai & Ng, 1994 in general external appearance to some extent, its relatively small size (CW <30 mm), having stripe patterned ambulatory legs and a distinctive ovalshaped gold-colour pattern on the third maxilliped. However, Jianghuaimon gen. nov. markedly differs from Bottapotamon, Huananpotamon and Neilupotamon by its unique G1 structure, which is pointed anterolaterally, subterminal segment slightly curved inwards, terminal segment large and very stout, inner margin strongly convex, tip truncated with wide opening almost same width as terminal segment (Fig. 3C–E, H–I). In contrast, the G 1 in Bottapotamon is pointed anteromedially, with the subterminal segment generally straight, terminal segment large and slender, inner margin concave, tip truncated with opening smaller than terminal segment width (cf. Gao et al. 2019: fig. 5); in Huananpotamon, pointed anteriorly or anteromedially, with the distal part of subterminal segment neck-shaped, terminal segment slender, inner margin with flap or projection, with small opening at pointed tip (cf. Dai 1999: pls. 63–73); and in Neilupotamon, pointed anterolaterally, with the subterminal segment generally straight, terminal segment stout, inner margin almost straight to slightly convex, tip truncated with wide opening almost as wide as the terminal segment (cf. Dai 1999: pls. 201–204). Jianghuaimon gen. nov. can further be separated from Bottapotamon, Huananpotamon and Neilupotamon by differences in the carapace, male anterior thoracic sternites and male telson. See Table 1 for detailed comparisons. Moreover, Jianghuaimon gen. nov. was found to be syntopic with Longpotamon depressum, but can immediately be distinguished by its smaller size (CW <25 mm) (versus CW <50 mm in the latter), carapace anterolateral margin with 12–15 granules (Fig. 1A) (versus serrated, with 15–18 granules in the latter; Dai 1999: pl. XXII fig. 2), granules on anterolateral margin low and inconspicuous (Fig. 1A) (versus relatively large conspicuous in the latter; Dai 1999: pl. XXII fig. 2) and its G1 terminal segment large, stout, with rounded inner margin and wide opening at truncate tip (Figs. 3C–E, H–I) (versus relatively small G1 terminal segment with bifurcated tip in the latter; Dai 1999: pl. 179).Published as part of Zhao, Jun-Da, Xu, Yi-Yang & Huang, Chao, 2022, Jianghuaimon dabiense gen. nov. et sp. nov (Crustacea: Decapoda: Potamidae), a new genus and new species of freshwater crab from eastern-central China, pp. 431-440 in Zootaxa 5168 (4) on page 432, DOI: 10.11646/zootaxa.5168.4.3, http://zenodo.org/record/689974

Rhexoacrodictys melanospora S. X. Bao, R. J. Xu & Q. Zhao 2023, sp. nov.
No full textRhexoacrodictys melanospora S.X. Bao, R.J. Xu & Q. Zhao, sp. nov. Index Fungorum Number: IF559983. Facesoffungi Number: FoF 12898; Fig. 2. Etymology: The specific epithet ‘ melanospora ’ refers to the dark conidia of the fungus Saprobic on decaying woods in terrestrial habitat. Sexual morph: Undetermined. Asexual morph: Conidiophores 19–60 × 3–5 μm (Q = 40 × 4 μm, n = 20), macronematous, mononematous, erect, straight or somewhat fexuous, pale brown to brown, cylindrical, thick-walled, smooth, 2–4 septate. Conidiogenous cells 2–6 × 3–4 μm (Q = 4 × 3.5 μm, n = 10), monoblastic, integrated, terminal, pale brown, cylindrical, with 1–3 pale brown percurrent extensions. Conidia 16–32 × 12–21 μm (Q = 23 × 16 μm, n = 40), solitary, acrogenous, ellipsoidal to obovoid or somewhat subglobose, muriform, with 2–5 transverse and several oblique septa, pale brown when immature, becoming dark brown at maturity, thick and smooth-walled. Culture characteristics: Colonies on PDA, reaching 4 cm diam. after 15 days at room temperature (25 ˚C), colonies irregular, surface taupe, mycelium dense, and reverse blackish. Material examined:— CHINA. Yunnan Province, Fugong County, decayed wood in terrestrial habitats, 13 May 2021, Song Wang, GLG41-1 (HKAS 124580, holotype), ex-type KUNCC 22-12406; China, Derung-Nu Autonomous County of Gongshan, 15 May 2021, Song Wang, GLG41-2 (HKAS 124581, paratype), ex-paratype KUNCC 22- 12411. Notes: Rhexoacrodictys melanospora is easily distinguished by its macronematous, conidiophores, and conidia ellipsoidal, 2–5 transverse, and several oblique septate. R. melanospora clustered with R. erect and R. fimicola with strong bootstrap support (100% ML/1.00 BI). However, R. melanospora has shorter conidiophores than R. fimicola (19–60 μm vs. up to 75 μm) (Baker et al. 2002), R. erect has numerous irregular septa, and R. melanospora just has 2–5 transverse and several oblique septa (Baker et al. 2002, Zhao et al. 2011). Among the four species of Rhexoacrodictys (Index Fungorum 2023), R. broussonetiae and R. fuliginosa lack DNA sequences. Although their molecular data deficiency, R. melanospora clearly differs from R. broussonetiae and R. fuliginosa by its shorter conidiophores, 19–60 μm (vs. 70–90 μm in R. broussonetiae, and vs. up to 85 μm in R. fuliginosa) and longer conidia, 16–32 μm (vs. 17–28μm in R. broussonetiae, and vs. 17–27 μm in R. fuliginosa) (Baker et al. 2002, Zhao et al. 2011, Xiao et al. 2018).

Measurements. Body length: male 15.0–17.8 mm (holotype 23.5 mm), female 14.2–18.1 mm (allotype 18.1 mm); body width: male 7.8–9.1 mm (holotype 9.7 mm), female 8.1–10.0 mm (allotype 10.0 mm). Differential diagnosis. Didrepanephorus heterocolor new species is similar to D. nishiyamai and D. subvittatus, but the body color of the latter two species is reddish-brown. This new species can be separated from the latter two also by the following characters: antennal club bicolor (base dark brown and gradually changed fulvous to apex, Figs. 15–18), while unicolor in D. nishiyamai (Figs. 29–30) and D. subvittatus (Figs. 31–32); length of male antennal club as long as antennomeres 2–7 combined (Figs. 11–12), while longer in D. nishiyamai (Figs. 21–22) and shorter in D. subvittatus (Figs. 25–26); male mandibles deeply constricted before base tooth (Fig. 15), while slightly constricted in D. subvittatus (Figs. 31); anterior margin of male mentum slightly depressed in middle, while distinctly depressed in D. subvittatus; setae on male pronotum longer (Figs. 15–18) than that of D. nishiyamai (Fig. 29) and D. subvittatus (Fig. 31); female with dense and coarse punctures on head and pronotum (Figs. 13–14, 19–20), while those punctures sparser and finer in D. nishiyamai (Figs. 23, 30) and D. subvittatus (Figs. 27, 32). Etymology. The specific epithet “ heterocolor ” is a combination of the Greek “ heteros ” and Latin noun “ color ” meaning different colors, in allusion to the significant sexual dichroism of this new species. Distribution. China: Guizhou. Natural history. This species is only known from the Maolan Nature Reserve in southern Guizhou, China, where has a subtropical forest of karst landform at elevation of 550–850 m (Figs. 57–58). The mature larvae and newly emerged adults have been found in humid rotten wood in later April and early May (Figs. 59–60, 63), and an exhausted female was collected by a light trap in early June 2018. It is suggested the peak of activity for adults should be mid and later May. In the field, third instar larvae of the new generation can be excavated in rotten wood of broad-leaved trees as early as late July (Fig. 60). Wild-collected larvae were raised in small plastic containers filled with pieces of wet, rotten oak wood at the temperature below 26°C. Females have been bred for reproduction under artificial conditions (Figs. 61–62, 64), and several larvae were successfully developed to the adult stage (personal observation, Jian-Yue Qiu, 2012–2013; Jun Qi, 2017–2018). Remarks. The body color of this new species is sexually dichroic, the male is dark brown, while the female has a black body with bicolor elytra. This phenomenon is distinctive in this genus, and D. arnaudi was the only case before. In general appearance, D. heterocolor new species is close to D. nishiyamai and D. subvittatus, and they can be attributed to a species group (D. subvittatus group) characterized by the combination of the following characters: lower margin of male mandible with a distinct concavity before basal tooth; pronotum evenly covered with untufted dense setae in male, with sparse short setae in female; abdominal ventrites with sparse setae; phallobase evenly curved in profile; parameres fused basally.Published as part of Qiu, Jian-Yue, Zhao, Ming-Zhi & Xu, Hao, 2021, Description of a new species of the genus Didrepanephorus Wood-Mason, 1878 (Coleoptera: Scarabaeidae: Rutelinae) from China with notes on allied species, pp. 493-513 in Zootaxa 4933 (4) on pages 498-501, DOI: 10.11646/zootaxa.4933.4.2, http://zenodo.org/record/455662
