No full textOchicanthon vazdemelloi Latha & Sabu sp. nov. (Figs. 61–65) Description. Body (Fig. 61) predominantly black. Dorsal surface of head glabrous, with annular punctures separated by intervals fairly equal to their diameter. Pronotum moderately convex in lateral view, outline at base almost in line with that of elytral suture; laterobasal paramarginal ridge absent. Pronotal punctations (Fig. 62) similar to that on head, but becoming sparser medially; setae almost indistinct, straight and recumbent. Elytra strongly convex, lacking tubercles, suture conspicuously raised, except on apical quarter; striae shallow, wide, consisting of chains of circular depressions joined by straight sulci (Fig. 62); interstriae moderately convex, uneven, covered with fine, sparse setiferous punctures arranged in two rows; background microsculpture smooth; setae stout, arcuate and semi-erect, but never scale-like; lateral ridge posteriorly extended to level of apex of second stria. Mesosternum impunctate, meso-metasternal line subangulate; metasternal shield coarsely punctate, except in the centre, which is smooth (Fig. 63). Pygidium rather uniformly covered with shallow annular setiferous punctures. Male with base of metafemur forming a distinct angle and base of metatibia slender and arcuate. Protrochanter with outer margin arcuate. Hind wings absent. Aedeagus as in Figs. 64–65. Measurements (mm; n = 5): TL = 4.3 –5.0; BW = 2.7– 3.2; PL = 1.3–1.7; PW = 2.3–2.7; EL = 2.4–2.7. Type material: Holotype (male, in NPC): “ India, Kerala, Palghat District, Silent Valley National Park, 2010 m, montane evergreen forest, dung baited pit fall trap, 5.vi. 2009, leg. Vinod, K.V.” Paratypes (4): Same data as holotype, 3 females in NPC, SJC and ZSI-Ca; “ India, Kerala”, 1 male in MHNG. Distribution and natural history. Southwest India ( upper montane cloud forests at Silent Valley in the South Western Ghats montane rain forest ecoregion). Etymology. Named in honor of Fernando Z. Vaz-de-Mello, Veracruz, Brazil, who renamed the genus in 2003. Diagnosis. Only two Indian Ochicanthon species, O. devagiriensis and O. vazdemelloi, have the elytral pubescence arranged in rows. Ochicanthon vazdemelloi can be readily distinguished from O. devagiriensis by its indistinct pronotal pubescence. See diagnosis under O. besucheti and O. devagiriensis.Published as part of Latha, Mathews, Cuccodoro, Giulio & Sabu, Thomas K., 2011, Taxonomy of the dung beetle genus Ochicanthon Vaz-de-Mello (Coleoptera: Scarabaeidae: Scarabaeinae) of the Indian subcontinent, with notes on distribution patterns and flightlessness, pp. 1-29 in Zootaxa 2745 on page 22, DOI: 10.5281/zenodo.27662

IX. 2007, Shiju, T.R.” Paratypes (26): Same data as holotype, 15 females in SJC and ZSI-Ca; same data as holotype, but 2. IX. 2007, 5 females in KFRI; “ India, Kerala, Idikki District, Rajamalai (Eravikulam National Park), 2114 m, montane evergreen forest, dung baited pit fall trap, 5. XII. 2006, Vinod, K.V,” 4 females in NPC; “ India, Kerala,” 1 male and 1 female in MHNG. Distribution and natural history. South India (upper montane evergreen forests at Eravikulam National Park, in the South Western Ghats montane rain forest ecoregion). Etymology. Named after the local name ‘Devagiri’ of St. Joseph’s College, Calicut, Kerala State, India. Diagnosis. Within the genus, the presence of projecting tubercles on elytral disc is unique to O. devagiriensis. Among the four wingless Indian species of Ochicanthon (see diagnosis under O. besucheti), only O. devagiriensis and O. vazdemelloi have the elytral pubescence arcuate, semi-erect and arranged in rows. The only other Ochicanthon species to possess erect elytral pubescence arranged in rows is O. hanskii Krikken & Huijbregts, 2007, from Borneo, which is interestingly also the only non-Indian wingless species of the genus.Published as part of Latha, Mathews, Cuccodoro, Giulio & Sabu, Thomas K., 2011, Taxonomy of the dung beetle genus Ochicanthon Vaz-de-Mello (Coleoptera: Scarabaeidae: Scarabaeinae) of the Indian subcontinent, with notes on distribution patterns and flightlessness, pp. 1-29 in Zootaxa 2745 on pages 7-10, DOI: 10.5281/zenodo.27662

SIGAN: a generative adversarial network architecture for sketch to photo synthesis
Get PDFOf late, with the rise of artificial intelligence (AI) and deep learning (DL) models, image translation has become a very important phenomena which could produce realistic photographic results. Synthesizing new images is widely used in different applications including the ones used by investigation agencies. Image generation from hand-drawn sketch to realistic photos and vice versa is required in different computer vision applications. Generative adversarial network (GAN) architecture is extensively employed for generating images. However, there is need for investigating further on improvising GAN architecture and the underlying loss functions towards leveraging performance. In this paper, we put forth a GAN architecture known as sketch-image GAN (SIGAN) for synthesizing realistic photos from hand-drawn sketches. Both generator (G) and discriminator (D) components are designed based on DL models following a non-cooperative game theory towards improving image generation performance. SIGAN exploits improvised image representation and learning of data distribution. The algorithm we have proposed is known as learning-based sketch-image generation (LbSIG). This algorithm exploits SIGAN architecture for efficiently generating realistic photo from given hand-drawn sketch. SIGAN is assessed using a benchmark dataset called CUHK face sketch database (CUFS). From the empirical study, it is observed that the proposed SIGAN architecture with underlying deep learning models could outperform existing GAN models in terms of Fréchet inception distance (FID) with 38.2346%
Expedient Case Study of Irreproachable Partaking of Metropolis Concoction in the Dominion of Impecunious Civilization
No full textIn this survey, we have taken fanatical curiosity over a metropolis conglomerate. We have gathered congregated statistics regarding
community trash across the city. Later we have undergone for creating righteous cognizance to the people of predefined cities. Where, the entire city is totally being overflowed up by community wastages namely plastic, electronic, plant, human and many more. So, we have testified the best possible modus operandi to eradicate aforesaid evils. Modus operandi which provides alternative methods evicts tribulations. These tribulations interestingly take place in developing countries like India. All the pertinent aspects have expounded in the impending part of this community survey
Impact of Hardening Process On Reorientated Thermally- Treated Carbon Steel Cutting Tool Materials
No full textIn this research work, we have found the tool wear rate of the materials of high-speed steel and Titanium alloy which are having optimum composition of carbon and other constituents. Here we have expounded the distinguishing characteristics of high-speed steel and Titanium alloys in respect to the tool wear. Subsequently, we carried out a heat treatment process, where two machined specimens were kept inside the muffle furnace once it attained required temperature, it was maintained at that temperature for a certain period of time and then cooled back to room temperature, we conducted a hardness test, tool wear test. In addition to these cutting operations have been performed over mild steel and aluminium workpieces

Differs from C. urticicola in having floccose velar remnants on pileus, stipe with a somewhat marginate bulbose base, basidiospores with a round base, 5–6 psuedoparaphyses surrounding each basidium, clavate pleurocystidia with apical lobes, smooth velar elements on the pileipellis, and distinctive nrITS and nrLSU sequences. Holotype:— INDIA. Kerala State: Kozhikode District, Calicut University Campus, 11°07’56.5” N 75°53’32.1” E, 12 August 2016. K. G. Greeshma Ganga G63 (CALI). GenBank accessions: OP 549280 (nrITS), OP 549279 (nrLSU). Description:— Basidiocarps very small, fragile. Pileus 3–6 mm diam. when mature, initially ovoid, paraboloid or cylindrical, then expanding to broadly paraboloid to convex; surface pure white when young, becoming orange gray (5B2/OAC760) with white velar remnants, initially completely covered with a thick floccose veil that later splitting into superficial, velar patches all over; margin initially incurved to straight, becoming decurved or slightly revolute, often fissile, deliquescent at maturity. Lamellae free, crowded, initially white, becoming dark brown (7F7/OAC733) with age; edge not observed due to deliquescence. Stipe 11–15 × 0.5–1 mm, central, tapering towards the apex, hollow; surface white, finely squamulose all over, slightly floccose towards the base; base somewhat marginate-bulbous with profuse basal mycelium. Odor and taste not distinctive. Basidiospores (n = 80) 6–8(9) × 5–7.5 × 5–6 µm, on an average 7.22 × 6.2 × 5.47 µm, Q 1 = 1–1.4, Q 1avg = 1.17, Q 2 = 1–1.4, Q 2avg = 1.23, lenticular, subglobose to ovoid with rounded base and apex, ellipsoid in side view, brown, thickwalled, with a central germ-pore up to 2 µm wide. Basidia 15–20 × 6–9 µm, clavate to pedicellate-clavate, hyaline, slightly thick-walled, surrounded by 5–6 pseudoparaphyses, 4-spored; sterigmata up to 3 µm long. Pleurocystidia 13–22 × 7–15 µm, broadly clavate with 2–3 lobed apex, hyaline, thin-walled. Lamella-edge not observed due to deliquescence. Cheilocystidia not observed. Pileipellis a cutis frequently disrupted by clumps of velar elements; hyphae 3–5 µm wide, subcylindrical, hyaline, thin-walled; velar elements 17–50 × 5–15 µm, branched, coralloid, hyaline, slightly thick-walled. Stipitipellis a cutis disrupted with velar elements; hyphae 3–8 µm wide, hyaline, slightly thick-walled; velar elements 5–14 × 2–8 µm, almost similar to the velar elements on the pileipellis, hyaline, slightly thick-walled. Clamp connections not observed on any hyphae. Habitat:—In small groups or scattered, on decaying twigs or rotten fruit pods of rubber tree (Hevea brasiliensis). Geographical distribution range:—Known only from the type locality in Kerala State, India. Additional specimens examined:— INDIA. Kerala State: Kozhikode District, Calicut University Campus, 11°07’56.5” N 75°53’32.1” E, 23 July 2016, K. G. Greeshma Ganga G23 (K. P. Deepna Latha personal herbarium). GenBank accessions: OP 549038 (nrITS), OP 549277 (nrLSU). Comments:—Smaller basidiocarps, deliquescent lamellae, subglobose basidiospore and a cutis-type pileipellis with colorless and coralloid velar elements place C. minuta in the sect. Coprinopsis. Coprinopsis urticicola (Berkeley & Broome 1861: 376) Redhead, Vilgalys & Moncalvo (2001: 232), a species originally described from North America (Uljé 2005) and also reported from East Africa (Pegler 1977), Europe and Iran (Asef et al. 2015), seems to be close to C. minuta in having almost similar-sized basidiospores (5.5–9 × 4.5–6.5 µm), coralloid velar elements on the pileipellis, absence of clamp connections, and a lignicolous habitat. However, C. urticicola differs from C. minuta in having a pileus with woolly-hairy velar scales, basidia surrounded by 5–8 psuedoparaphyses, basidiospores with a conical base, utriform to subcylindrical pleurocystidia, and a pileipellis with strongly encrusted velar elements. Coprinopsis kubickae (Pilát & Svrček 1967: 142) Redhead, Vilgalys & Moncalvo (2001: 229), reported from Europe (Uljé 2005), shares some similarities with C. minuta in having basidiocarps with an ochre brown to grayish pileus, stipe with an enlarged base, and coralloid velar elements on pileipellis. However, C. kubickae has minute, flocculose velar remnants on pileus, larger basidiospores (7–11 × 6–10 µm) with central to eccentric germ-pore and conical base, 5–8 psuedoparaphyses surrounding each basidium, a hymenium with utriform to subcylindrical pleurocystidia, clamped hyphae, and a habitat on soil (Uljé 2005). In a BLASTn search using the nrITS (676 bp) sequence, the closest hit was an unidentified Basidiomycota species PCT.10 (HQ248225: 99.70%) followed by C. urticicola (MH748639: 95.96 %). While using the nrLSU (956 bp) sequence, C. urticicola (HQ847101: 99.36 %) was resulted as the closest hit.Published as part of Greeshma Ganga, K. G., Manimohan, Patinjareveettil & Deepna Latha, K.

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
