A Fourier-Based Valuation Method for Bermudan and Barrier Options under Heston’s Model
Get PDFWe develop an efficient Fourier-based numerical method for pricing Bermudan and discretely monitored barrier options under the Heston stochastic volatility model. The two-dimensional pricing problem is dealt with by a combination of a Fourier cosine series expansion, as in [F. Fang and C.W. Oosterlee, SIAM J. Sci. Comput., 31 (2008), pp. 826–848, F. Fang and C. W. Oosterlee, Numer. Math., 114 (2009), pp. 27–62], and high-order quadrature rules in the other dimension. Error analysis and experiments confirm a fast error convergence.Delft Institute of Applied MathematicsElectrical Engineering, Mathematics and Computer Scienc

Le pluriel en fang ntumu
Get PDFLe fang est une langue bantu, il comporte cinq dialectes dont fait parti le ntúmú. Le fang ntúmú est une langue à classe. Tous les nominaux d’une classe gouvernent le même accord et la langue leur affecte un indice de type préfixal : le préfixe nominal.Le préfixe nominal apporte des informations sur la classe, mais également sur le nombre. Les travaux menés au sujet du pluriel en fang ntúmú montrent que celui-ci est obtenu par l’agencement de deux préfixes : celui du pluriel et du singulier.Nous montrerons pour notre part qu’il s’agit en réalité d’une construction préfixale complexe de type CVN, ce qui serait assez novateur puisque le préfixe nominal dans les langues bantu est généralement de type Ø-, C-, V- ou CV-. Notre communication s’inscrit dans le deuxième axe des RJC qui définit le cotexte comme l’ensemble des unités linguistiques.Fang is a bantu language. It contains 5 dialects and ntúmú is one of them. Fang ntúmú makes classification of his nouns. All nouns of the same class govern the same agreement, and the language allocates to them a prefixal mark: the nominal prefix. The nominal prefix brings information not only about the class of every noun, but also about number. Some works about the plural in fang ntumu show that this one is obtained by the arrangement of two prefixes: that of plural and that of singular. We shall show for our part that the plural is really obtained by a complex prefixal construction with tree elements: a consonant, a vowel and a nasal. So, his structure is CVN.

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Clorindaia latiabdoma Blocker & Fang
No full textClorindaia latiabdoma Blocker & Fang (Figs. 22A 3, 22B 3, 22Q, 27) Clorindaia latiabdoma Blocker & Fang, 1992: 344 [original description, illustration, morphology]; Zanol, 2008: 24 [catalogue]; Zahniser, 2007 [online catalogue]; Freytag & Gaiani, 2017 [online catalogue] Diagnosis. The male of C. latiabdoma is not known, making it difficult to establish its identity. However, the coloration of the face of the female appears to be unique in the genus: clypellus mostly dark brown, with some areas of lighter coloration; lorum ivory; gena dark brown laterad of lorum, otherwise ivory to tawny except for some dark brown above and below antennal pit; frontoclypeus ivory to tawny centrally, with pair of poorly defined broad brown markings extending from clypellus to antennal pits. The measurement reported by Blocker & Fang (1992) of 4.8 mm is confirmed here. Material examined. Holotype ♀ [SEMC]. Distribution. This species is known only from the type locality in Paraguay (Caaguazú Dept.). Remarks. This species is known only from a single female. The unique coloration of the face may help to identify males and clarify the identity of this species in the future.Published as part of Zahniser, James N., 2021, Revision of the New World leafhopper tribe Faltalini (Hemiptera: Cicadellidae: Deltocephalinae) and the evolution of brachyptery, pp. 1-160 in Zootaxa 4954 (1) on page 45, DOI: 10.11646/zootaxa.4954.1.1, http://zenodo.org/record/469077
