k-uniformly multivalent functions involving Liu-Owa q-integral operator
No full textIn this paper, we introduce q-analogue of Liu-Owa integral operator and define k-uniformly multivalent starlike functions of order gamma, (0 <= gamma < p; p is an element of N) by using Liu-Owa q-integral operator. We examine coefficient estimates, growth and distortion bounds for the functions belonging to the subclass of k-uniformly multivalent starlike functions of order gamma. Moreover, we determine radii of k- uniformly starlikeness, convexity and close-to-convexity for the functions belonging to this subclass

No full textGastrochilus wenshanensis Q. Liu, D.P. Ye & X.H. Jin, sp nov. (Ẋψfiffi±) (Figure 4–5) Type:— CHINA. Yunnan Province: Wenshan Zhuang-Miao Autonomous Prefecture, Malipo County, Xiajinchang Village, limestone forest, 2155 m, 16 June 2016, Qiang Liu 342 (holotype: HITBC0056874!). Morphologically, it is similar to Gastrochilus tsii for having a pendulous and branched stem and a fleshy and glabrous epichile, but differs from the latter by the yellow-green flowers, petals oblanceolate with an acute apex, the slightly erose margin of the epichile, and the absence of purple stripes along the margin of the hypochile. Description:— Epiphytic herbs. Stem pendulous, 12–18 cm long, with 0.4–0.6 cm internodes, slender, often branched. Leaves alternate, distichous, ovate, 1.3–1.6 × 0.4–0.7 cm; apex acuminate and unequally 2-lobed with 1 awn (young leaf). Inflorescences several, opposite to leaves, subumbellate, 4–6-flowered; peduncle 1.6–2.7 cm long, slender, upper part enlarged, lower part with 2 sheaths; floral bracts ovate-lanceolate, ca. 1.5 mm long; pedicel and ovary 3.2–4.0 mm long. Flowers yellow-green. Dorsal sepal oblong-elliptic, concave, 3.0–3.2 × 2.0– 2.2 mm, apex acute. Lateral sepals similar to dorsal sepal, 3.8–4.0 × 2.0– 2.2 mm, apex acute. Petals oblanceolate, 3.5–3.8 × 1.6–1.8 mm, apex acute. Lip with an epichile and a saccate hypochile; epichile sub-triangular, 2.5–2.8 × 5.0– 5.2 mm, fleshy, yellowish, adaxially glabrous, margin slightly erose, apex rounded; hypochile nearly cupular, with 3-ridges externally, 4.0– 4.5 mm tall, 4.0– 4.2 mm in diameter. Column stout with purple spots, ca. 1.0 mm; rostellum bilobed with acuminate apex; pollinia 2, subglobose, ca. 0.3 mm in diameter; stipe elongate, ca. 1.2 mm; viscidium elliptic, thick and bilobed; anther cap galeate with recurved–acuminate apex, 1.5 × 1.2 mm; Capsules not seen. Distribution and ecology:— This new species occurs in Malipo County, Yunnan Province, China. It grows on the rock at altitudes from 2055 to 2155 m in the limestone broad-leaved forests. Gastrochilus wenshanensis was observed flowering from June to July in the wild. Etymology:—Referring to the type locality, Wenshan Zhuang-Miao Autonomous Prefecture, Yunnan Province, China. Additional specimens examined(paratype):— CHINA: Yunnan Province: Wenshan MiaoAutonomous Prefecture, Malipo County, Xiajinchang Village, limestone forest, 2055 m, 16 June 2016, Qiang Liu 375 (HITBC 0056905!). Taxonomic discussion:— According to the characteristic of the long and pendulous stem, G. wenshanensis can be placed in section Microphyllae (Tsi 1996). However, some species were isolated from section Microphyllae by having dense hairs on the epichile, and clustered into clade V (Liu et al. 2019). While, other species with glabrous epichile were clustered into clade IV and new species of G. tsii and G. wenshenensis should be placed in this clade.Published as part of Liu, Qiang, Wu, Xun-Feng, Zhou, Shi-Shun, Li, Jian-Wu & Jin, Xiao-Hua, 2023, New species and record of Gastrochilus (Orchidaceae, Aeridinae) from China and Laos, pp. 210-224 in Phytotaxa 585 (3) on page 216, DOI: 10.11646/phytotaxa.585.3.3, http://zenodo.org/record/769080

Variational method to a fractional impulsive (p,q) -Laplacian coupled systems with partial sub- (p,q) linear growth
No full textAbstract In this paper, by using the least action principle, an existence result of nontrivial weak solutions for a class of fractional impulsive coupled systems with (p,q) -Laplacian is obtained if the nonlinear term has sub- (p,q) linear growth, and by using an extension of Clark’s theorem, infinitely many solutions of the system are obtained if the nonlinear term has partial sub- (p,q) linear growth
Emergy-based evaluation of world coastal ecosystem services
No full textThe current lack of research on the evaluation of marine ecosystem services makes the value of marine protection, development and restoration underestimated during the decision-making process. Based on the non-monetary ecosystem service evaluation framework, a marine ecosystem service classification and accounting method has been established in this study, and the world's coastal ecosystem services have been measured as an example. The results show that (1) the world's coastal ecosystem service value is about 4.13E+23 sej/yr, of which Asia and North America contribute about 55% of the total service value; (2) the top ten countries in terms of the world's coastal ecosystem service values are Canada, Indonesia, Australia, the United States, Brazil, the Russian Federation, Norway, the Philippines, Mexico, and China, which contribute about 60% of the total service value; (3) estuaries have the highest ecosystem service values, followed by mangroves, seagrass beds, tidal flats, salt marshes, and warm water coral reefs; (4) developed countries can make better use of their coastal resources and pay more attention to the marine protection while the opposite is true in developing countries, which means that developed countries still occupy an advantageous position in the process of marine protection, development and utilization. This study assesses the coastal ecosystem service values in various coastal countries from the perspective of ecosystem contributors, emphasizes the importance of protecting them in marine management, and provides a certain reference basis and theoretical support for decision-makers in formulating marine-related protection and development strategies

Yunnan Province: Zhenyuan County, Jiujia town, Qianjiazhai Village, Ailaoshan National Nature Reserve. Monsoon evergreen broad-leaved forest, 2300 m, epiphytic on tree trunks, 09 May 2016, Qiang Liu 354 (holotype: HITBC0056888!). Morphologically, it is similar to G. distichus (Lindley 1858: 36) Kuntze (1891: 661) and G. pseudodistichus (King & Pantling 1896: 341) Schlechter (1913: 315) by having the pendulous and branched stem, but differs from G. distichus by having a sub-triangular epichile without conic calli at base—from G. pseudodistichus by having oblong-elliptic sepals, and sub-triangular epichile wider than hypochile. Description:— Epiphytic herbs. Stem pendulous, 15–20 cm long, with 0.5–0.7 cm internodes, slender, often branched with tiny red-purple spots. Leaves alternate, distichous, ovate, 2.2–1.3 × 0.3–0.5 cm; apex acuminate and unequally 2-lobed with one awn. Inflorescences several, subumbellate, 3–4-flowered; peduncle 0.9–1.1 cm, slender, upper part enlarged, lower part with 2 sheaths; floral bracts ovate-lanceolate, 1.0– 1.2 mm; pedicel and ovary 0.3–0.4 cm. Flower yellow-green, sepals and petals with reddish brown spots. Dorsal sepal oblong-elliptic, concave, 3.2–3.8 × 2.0– 2.2 mm, apex acute. Lateral sepals similar to dorsal sepal, 3.2–4.2 × 2.0– 2.4 mm, apex acute; petals ovate, 3.0–3.2 × 1.5–1.6 mm, apex obtuse. Lip with an epichile and a saccate hypochile; epichile sub-triangular, 2.8–3.0 × 5.0– 5.5 mm, fleshy, adaxially glabrous, apex rounded; hypochile nearly cupular, mouth with lateral purple stripes, sac with reddish brown spots on the underside, 4.0– 4.5 mm tall, 4.0– 4.2 mm in diameter. Column stout with purple spots, ca. 1.2 mm; rostellum bilobed acuminate at the apex; pollinia 2, subglobose, ca. 0.3 mm in diameter; stipe elongate, ca. 0.7 mm; viscidium elliptic, thick and bilobed; anther cap galeate with a recurved–acuminate apex, 1.6 × 1.4mm. Capsules cylindrical, with 3 ridges, 2.0–2.2 × 0.7–0.8 cm. Distribution and ecology:— The new species was found in Zhenyuan County, Dali Autonomous Prefecture, Yunnan Province, China, and Darjeeling state, India. Gastrochilus tsii grows on the tree trunks or rocks at altitudes from 2150 to 2300 m in Monsoon evergreen broad-leaved forest. Gastrochilus tsii was observed flowering from June to July in the wild. Etymology:— The species epithet honors the late Prof. Tsi zhanhuo, (1936–2001), who devoted all his life to study Chinese orchids. Taxonomic discussion:— After checking the specimens of Gastrochilus spp. kept at K, we found one specimen (voucher J.S. Gamble 8006) with drawing, collected by J.S. Gamble in 1879, from Darjeeling state, India (Figure 3G), identified as the G. distichus. It is easily distinguished from G. distichus by the illustrated flower characters. During our field expeditions in Yunnan province, we collected the fresh materials and the vegetative and floral characteristics are in congruity with the illustration of the Gamble specimen.Published as part of Liu, Qiang, Wu, Xun-Feng, Zhou, Shi-Shun, Li, Jian-Wu & Jin, Xiao-Hua, 2023, New species and record of Gastrochilus (Orchidaceae, Aeridinae) from China and Laos, pp. 210-224 in Phytotaxa 585 (3) on pages 211-216, DOI: 10.11646/phytotaxa.585.3.3, http://zenodo.org/record/769080
