L-P error estimates and superconvergence for covolume or finite volume element methods
No full textWe consider convergence of the covolume or finite volume element solution to linear elliptic and parabolic problems. Error estimates and superconvergence results in the L-p norm, 2 less than or equal to p less than or equal to infinity, are derived. We also show second-order convergence in the L-p norm between the covolume and the corresponding finite element solutions and between their gradients. The main tools used in this article are an extension of the "supercloseness" results in Chou and Li [Math Comp 69(229) (2000), 103-120] to the L-p based spaces, duality arguments, and the discrete Green's function method.

Taeniothrips grisbrunneus Feng, Chou & Li, comb.n.
No full textTaeniothrips grisbrunneus (Feng, Chou & Li) comb.n. Megalurothrips grisbrunneus Feng, Chou & Li, 1995: 15. Described from Shaanxi, China on three females and three males, the original description and figures suggest that this species is not a member of the genus Megalurothrips because of the following character states: tergite VIII with a long and complete posteromarginal comb; male abdominal sternites III–VII each with a large pore plate; fore wing first vein setal row widely interrupted. These characters indicate that grisbrunneus is a species of Taeniothrips. However, the original illustration of the head indicates a curious proliferation of small setae both in front of the ocellar triangle and also near the posterior margin of the vertex. Unfortunately the type specimens are not available for study, and the significance of this apparently unique chaetotaxy cannot be verified. Despite this illustration, grisbrunneus is probably closely related to picipes, a widespread Holarctic species that has been recorded in China from both Shaanxi and Henan (Mirab-balou et al. 2014).Published as part of Mirab-Balou, Majid, Mound, Laurence A. & Tong, Xiao-Li, 2015, New combinations and a new generic synonym in the genus Taeniothrips (Thysanoptera: Thripidae), pp. 371-378 in Zootaxa 3964 (3) on page 373, DOI: 10.11646/zootaxa.3964.3.6, http://zenodo.org/record/24055

Lynn Chou oral history interview and transcript
No full textThis recording and transcript form part of a collection of oral history interviews conducted by the Chao Center for Asian Studies at Rice University. This collection includes audio recordings and transcripts of interviews with Asian Americans native to or living in Houston.Lynn Chou was born in Taipei, Taiwan in 1958 where she grew up as a self-proclaimed
tomboy in a middle-class family. She came to America after undergraduate school to be a graduate at the
University of Houston after receiving a scholarship to study geophysics in an overwhelmingly maledominated
lab. While still enrolled in school she was offered a job with Texaco where she ended up
working for 18 years before transferring to Chevron from which she retired after another 18 years.
Throughout her years working she developed a deep sense of caring for her co-workers and credits those
personal relationships for her success as a higher-level boss. After retiring at the age of 60, she is now
ready to travel the world with her family and continue volunteering her time to local Houston

Ahlbergia chalcidis Chou & Li

Material. CHINA: Yunnan province: 1 ♂ (CHH), Lijiang City, Yulongxueshan, 2900m, 10.V. 2014, H. Huang leg.; 3 ♂♂, 2 ♀♀ (CHH), Lijiang, Yulongxueshan, 2600m, 26.IV. 2015, H.

Yang leg.; 2 ♂♂, 1 ♀ (CHH), Diqing Tibetan Autonomous Region, Deqin County, 2900m, 27.V. 2009, L. Ding leg.. All specimens dissected. Remarks. Beside holotype, a topotypic male specimen was figured by Huang & Zhou (2014: 146, figs. 25– 26); the photos of these two specimens are basis of identification for A. chalcidis. Male specimens from Lijiang were identified by their external similarities to specimens from Kunming. It should be noted that Lijiang shares all the Ahlbergia fauna with Kunming and both areas are occupied by A. chalcidis, A. circe montivaga Johnson, 1992, A. prodiga Johnson, 1992 and A. clarolinea. Relationship between A. chalcidis and A. chalybeia is still uncertain; more specimens of A. chalybeia from Hubei need to be examined in the future. The lamella postvaginalis of female genitalia of A. chalcidis is varied from the type as shown in Fig. 111 to the types resembling that of A. clarolinea as shown in Fig. 108 and that of A. chalybeia as shown in Fig. 110. The ductus bursae of A. chalcidis is as wide as that of A. chalybeia, but is constantly wider than that of A. clarolinea. Therefore it is likely that A. chalcidis represents a geographical variation of A. chalybeia. Both A. chalcidis and A. clarolinea fly together at least in three localities: Yulongxueshan, Ludian and Kunming. The two species are markedly different in wing-characters, length of saccus of male genitalia, shape of tegumen of male genitalia in lateral view and width of ductus bursae of female genitalia. Distribution. Yunnan (Kunming, Deqin, Lijiang).Published as part of Huang, Hao & Zhu, Jian-Qing, 2016, Ahlbergia maoweiweii sp. n. from Shaanxi, China with revisional notes on similar species (Lepidoptera: Lycaenidae), pp. 409-433 in Zootaxa 4114 (4) on pages 430-431, DOI: 10.11646/zootaxa.4114.4.3, http://zenodo.org/record/27160
