This new species can be distinguished from its congeners by the male flagellum having a deep notch at base containing a cluster of smaller scales that are arranged in helix shape. The male genitalia resemble those of D. paradichromella, but differ in the transtilla being ovate at connection and the lateral lobes of the juxta truncate at apex. In D. paradichromella, the transtilla is band-like at connection, and the juxta lateral lobe is rounded. Description. Adult (Fig. 3) with wingspan 17.5̅27.0 mm. Head yellowish white to golden yellow. Antenna brown to blackish brown, male scape about 2.5 times as long as wide, basal several flagellomeres incurved, forming a deep notch containing a cluster of smaller scales arranged in helix shape; female scape shorter, flagellum simple. Labial palpus upturned just beyond vertex, grayish brown to blackish brown; third segment slightly shorter than second segment. Maxillary palpus blackish brown. Patagium, tegula and thorax grayish brown to blackish brown. Forewing grayish brown to blackish brown, individual scales grayish white-tipped; antemedial line ill-defined, grayish white, from costal 1/4 sinuate to dorsal 2/5, incurved at CuP, bordered by ill-defined sub-triangular black patch on its outer margin near costa and on its inner margin near dorsum; discal spots black, separated; postmedial line grayish white, sinuate, incurved at M 1 and near CuA 2, edged with black; terminal line black; cilia grayish brown to blackish brown. Hindwing pale grayish brown to fuscous brown; cilia brown. Legs grayish brown to blackish brown, midleg and hindleg grayish white at apex of each tarsomere. Abdomen yellowish brown to blackish brown, edged with grayish yellow on posterior margin of each segment, sometimes light-colored on ventral surface. Male genitalia (Fig. 14). Uncus triangular, longer than width at proximal base, rounded at apex. Gnathos clubbed, about half length of uncus. Transtilla produced in V shape posteriorly; postero-lateral lobe three times length of its medial width, tapered from base to narrowly rounded apex, forming an acute angle of about 45°. Valva 2.5 times as long as wide, gradually broadened toward rounded apex; clasper an indistinct mastoid process at basal 1/5, bearing short setae; costa about 4/5 length of valva, slightly narrowed distally; sacculus 2/7 length of valva, basal 1/3 subtriangular, smooth, distal 2/3 spatulate, with long setae. Juxta V-shaped, lateral lobes slightly shorter than gnathos, digitate, truncate at apex, bearing sparse setae in distal half. Vinculum U-shaped, length same as maximum width. Phallus about 1.2̅1.4 times length of valva, with sclerotized crimples and a bundle of spines in distal half. Female genitalia (Fig. 25). Papillae anales large and wide, with sparse setae, rounded at apex. Apophyses posteriores and anteriores short, about equal length. Eighth segment broad and short. Antrum lip-shaped. Ductus bursae membranous, uniform in width, about 1.5 times length of corpus bursae, granulate on inner wall except near antrum. Corpus bursae ovate, 1.5 times as long as wide, granulated in posterior half; signum a rounded, invaginated cup consisting of concentrically arranged granules, situated at posterior 1/3 of corpus bursae. Ductus seminalis originating from posterior 2/5 of corpus bursae. Distribution. China (Gansu, Guizhou, Henan, Hubei, Shaanxi, Sichuan). Etymology. The specific name is derived from the Latin prefix antenn -, meaning antenna, and the Latin word alveatus, meaning notched, referring to the deep notch at base of flagellum in male.Published as part of Ren, Yingdang, Yang, Linlin, Liu, Hongxia & Li, Houhun, 2020, Taxonomic review of the genus Dusungwua Kemal, Kizildağ & Koçak, 2020 (Lepidoptera: Pyralidae), with descriptions of six new species and propositions of synonyms, pp. 341-365 in Zootaxa 4894 (3) on pages 343-346, DOI: 10.11646/zootaxa.4894.3.3, http://zenodo.org/record/431585

This new species can be separated from its congeners by the forewing black from the base to the inner margin of the antemedial line. The genitalia structures are similar to those of D. dichromella, differing in the male genitalia by the triangular uncus gradually narrowed to apex, the clubbed gnathos tapered to a hooked apex; and in the female genitalia by the subtriangular corpus bursae twice as long as the maximum width and the signum situated in the middle of the corpus bursae. In D. dichromella, the uncus is subtriangular in the basal half, sharply narrowed at middle and tubular in the distal half, the gnathos is broadened in distal half and the apex is not hooked in the male genitalia; the elongate bag-shaped corpus bursae is 3.5 times as long as its maximum width, and the signum is situated at the anterior 2/7 of the corpus bursae in the female genitalia. Description. Adult (Fig. 4) with wingspan 21.5̅ 27.5 mm. Head grayish brown. Antenna grayish white, scape about twice as long as wide, male with basal several flagellomeres constricted, incurved, without scale tufts; female flagellum simple. Labial palpus upturned beyond vertex; first segment grayish brown mixed with grayish white; second and third segments about equal length, grayish brown to blackish brown. Maxillary palpus grayish brown mixed with grayish white. Patagium, tegula and thorax yellowish brown to brownish fuscous. Forewing black in basal area, from grayish white gradually to grayish brown in medial area, grayish brown in distal area; antemedial line white, from costal 1/3 obliquely outward to dorsal 2/7; discal spots indistinct, black, fused into a club shape; postmedial line grayish white, sinuate, incurved at M 1 and CuA 2; terminal line black; cilia grayish brown. Hindwing pale grayish brown; cilia brown basally, pale brown distally. Foreleg blackish brown with scattered white scales, midleg grayish brown mixed with white, hindleg grayish white; tarsi black except white at apex of each tarsomere. Abdomen with dorsal surface blackish brown except yellow at posterior margin of each segment, ventral surface yellowish brown. Male genitalia (Fig. 15). Uncus triangular, longer than width at proximal base, gradually narrowed to rounded apex. Gnathos about 2/3 length of uncus, clubbed, tapered to hooked and slightly bifurcate apex, apico-dorsal portion minutely serrated. Transtilla produced in V shape posteriorly; postero-lateral lobe three times length of its medial width, tapered from base to narrowly rounded apex, forming an acute angle of about 45°. Valva three times as long as wide, narrowed at base, gradually broadened to middle, then narrowed to rounded apex; clasper an indistinct mastoid process at basal 1/7, bearing short setae; costa about 5/6 length of valva; sacculus sinuate, clubbed, 2/7 length of valva. Vinculum U-shaped posteriorly, 1.3 times as long as wide, concave on lateral margins at anterior 1/3, rounded anteriorly. Juxta broad V-shaped; lateral lobes about 4/5 length of gnathos, clubbed, slightly widened to rounded apex, bearing sparse setae. Phallus slightly longer than valva, with sclerotized crimples, crimples granulate in distal half. Female genitalia (Fig. 26). Papillae anales large and wide, with sparse setae, rounded at apex. Apophyses anteriores slightly longer and stouter than apophyses posteriores. Eighth segment about 2.5 times as wide as long. Antrum a narrow transverse band. Ductus bursae short, about 1/4 length of corpus bursae, gradually broadened, posterior 2/5 smooth, anterior 3/5 granulate on inner wall. Corpus bursae not easily differentiated from ductus bursae, subtriangular, twice as long as maximum width, granulate on inner wall in posterior 1/5; signum a rounded, invaginated cup consisting of concentrically arranged granules, situated at middle of corpus bursae. Ductus seminalis originating from posterior 1/5 of corpus bursae. Distribution. China (Anhui, Beijing, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hebei, Henan, Hubei, Hunan, Jiangxi, Liaoning, Shaanxi, Shandong, Sichuan, Tianjin, Zhejiang). Etymology. The specific name is derived from the Latin prefix basi -, meaning basal, and the Latin word niger, meaning black, referring to the forewing black in the basal area.Published as part of Ren, Yingdang, Yang, Linlin, Liu, Hongxia & Li, Houhun, 2020, Taxonomic review of the genus Dusungwua Kemal, Kizildağ & Koçak, 2020 (Lepidoptera: Pyralidae), with descriptions of six new species and propositions of synonyms, pp. 341-365 in Zootaxa 4894 (3) on pages 346-348, DOI: 10.11646/zootaxa.4894.3.3, http://zenodo.org/record/431585
Post-accident stock returns of aircraft manufacturers based on potential fault
No full textThe literature has considered the market's response to the stocks of commercial airline carriers after their flights are involved in accidents. The aircraft manufacturer stock price, in the wake of a crash, has received considerably less attention in the literature. We analyze this response over a modern sample period and determine that a quick downturn of nearly 50 basis points of negative abnormal return accompanies the typical accident. Careful consideration of the cause of the accident, however, reveals a striking difference in market reaction based on the potential fault of the manufacturer. Market reactions are initially significantly negative when the manufacturer is judged to have potential fault in the incident but are otherwise insignificant. The market makes this determination even though there is often some ambiguity surrounding an accident's circumstances. We also find that manufacturer stock prices continue to drift significantly downward in the weeks following accidents that are deemed to potentially involve manufacturer fault.

VIX changes and derivative returns on FOMC meeting days
No full textWe examine the link between scheduled FOMC meetings and the VIX measure. Our results indicate that VIX declines significantly on scheduled meeting dates. Unlike prior studies suggesting that the drop in VIX is mechanical, we attribute the decline to the resolution of uncertainty regarding future interest rates provided by the meetings. We examine returns to investable positions on VIX. Though a decline in the VIX level commonly occurs on FOMC meeting dates, we find that significant returns may still be garnered from taking short-VIX positions in derivative markets, even after accounting for the bid-ask spread.Journal ArticlePre-printJEL classification: G14, E4

Adult (Fig. 31) with wingspan 18.0−23.0 mm. This species resembles E. marginans (Li et Zheng, 1998) in appearance. Encolapta epichthonia can be separated by the large body size, in the male genitalia by the valva not protruded at base on the ventral margin, and the aedeagus rounded at apex (Fig. 45), and in the female genitalia by the papillae anales obviouly narrowed posteriorly (Fig. 56). In E. marginans, the body size is much smaller (wingspan 11.0−16.0 mm); the valva is roundly protruded at base on the ventral margin and the aedeagus is truncate at apex in the male genitalia (Fig. 44); and the papillae anales are quadrate in the female genitalia (Fig. 55).

Investigation of Bandgap Properties of a Piezoelectric Phononic Crystal Plate Based on the PDE Module in COMSOL
No full textAiming to address the vibration noise problems on ships, we constructed a piezoelectric phononic crystal (PC) plate structure model, solved the governing equations of the structure using the partial differential equations module (PDE) in the finite element softwareCOMSOL6.1, and obtained the corresponding energy band structure, transmission curves, and vibration modal diagrams. The application of this method to probe the structural properties of two-dimensional piezoelectric PCs is described in detail. The calculation results obtained using this method were compared with the structures obtained using the traditional plane wave expansion method (PWE) and the finite element method (FE). The results were found to be in perfect agreement, which verified the feasibility of this method. To safely and effectively adjust the bandgap within a reasonable voltage range, this paper explored the order of magnitude of the plate thickness, the influence of the voltage on the bandgap, and the dependence between them. It was found that the smaller the order of magnitude of the plate thickness, the smaller the order of magnitude of the band in which the bandgap was located. The magnitude of the driving voltage that made the bandgap change became smaller accordingly. The new idea of attaching the PC plate to the conventional plate structure to achieve a vibration damping effect is also briefly introduced. Finally, the effects of lattice constant, plate width, and thickness on the bandgap were investigated

The strategic symbiosis between us Asian policy and Taiwanese nationalism
No full textThis thesis explores the influence of us Asian policy on the evolution of Taiwanese nationalism and the role of Taiwanese nationalism in America's Asian policy. The study consists of five parts. The first part (1895-1950) introduces the source of Taiwanese nationalism and America's strategic scheme on Taiwan before 1945, and explores American options after the germination of Taiwanese nationalism. America's intention to separate Taiwan from the mainland so as to deny the island to Chinese Communists late 1948 helped preserve inchoate Taiwanese nationalism. The second part (1950-1970) examines how America simultaneously exploited the Chinese Nationalist regime's anti-communism and facilitated the growth of Taiwanese nationalism in the bipolarized Cold-War era. The Truman administration's separatist intention after the Korean War, US aid and American scholars' Taiwan independence theories had significant implications for the evolution of Taiwanese nationalism. The third part (1970-1989) examines how America reconciled US-PRC rapprochement with its promotion of Taiwanese nationalism. Taiwan's democratisation evolved in the context of US political, economic and military intervention. During the transition to democratisation, secessionists turned political opposition movement into nation-building revolution. The fourth part (1989-2000) examines how US conservatives and Taiwanese nationalists jointly promoted Taiwanization. The dynamics of democratisation, native president Lee Teng-hui's domination of political agenda, the ambience of US-Taiwan strategic realignment and the maturity of political nationalism together facilitated Taiwanization. The fifth part (2000֊present) explores how America and Taiwan establish a strategic symbiosis for US-China strategic competition. The 9/11 Incident has little influence on the course of strategic symbiosis. The consolidation of Taiwan identity obliged thepan-blue camp to identify with Taiwan, promote political nationalism and deviate from their pro-unification ideology. The increased antagonism between Taiwanese nationalism and Chinese nationalism ossifies the symbiotic partnership between USAsian policy and Taiwanese nationalism and hinders China's rise to regional hegemonyand global superpower
