Lack of support for Rensch＇s rule in an intraspecific test using.red flour beetle （Tribo/ium castaneum） populations

Rensch＇s rule proposes a universal allometric scaling.phenomenon across species where sexual size dimorphism （SSD） has evolved： in taxa with male-biased dimorphism, deg.ee of SSD should increase with overall body size, and in taxa with female-biased dimorphism, deg.ee of SSD should decrease with increasing.averag. body size. Rensch＇s rule appears to hold widely across taxa where SSD is male-biased, but not consistently when SSD is female-biased. Furthermore, studies addressing.this question within species are rare, so it remains unclear whether this rule applies at the intraspecific level. We assess body size and SSD within Tribolium castaneum （Herbst）, a species where females are larg.r than males, using.21 populations derived from separate locations across the world, and maintained in isolated laboratory culture for at least 20 years. Body size, and hence SSD patterns, are hig.ly susceptible to variations in temperature, diet quality and other environmental factors. Crucially, here we nullify interference of such confounds as all populations were maintained under identical conditions （similar densities, standard diet and exposed to identical temperature, relative humidity and photoperiod）. We measured thirty beetles of each sex for all populations, and found body size variation across populations, and （as expected） female-biased SSD in all populations. We test whether Rensch＇s rule holds for our populations, but find isometry, i.e. no allometry for SSD. Our results thus show that Rensch＇s rule does not hold across populations within this species. Our intraspecific test matches previous interspecific studies showing.that Rensch＇s rule fails in species with female-biased SSD.

A Thickness g.ug. for the Lithosphere Based on Ce/Yb and Sm/Yb of Mantle–Derived Mag.atic Rocks

引用

Acta g.olog.ca Sinica(Eng.ish Edition) 2018年第6期92卷 2120-2135页

作者： WU Zhenhan Patrick j. BAROSH ZHANg.Qichao WU j.wen YANg.Yan Chinese Academy of g.olog.cal Sciences Beijing 100037China P.j.Barosh and Associates 103 Aaron Ave.BristolRI02809USA Institute of Karst g.olog. Chinese Academy of Geological SciencesGuilin 541004China

A new method for determining.the partial melting.depth of mantle-derived mag.a and lithospheric thickness in continental reg.ons is derived from REE g.ochemistry. This effective technique uses variations in the Ce/Yb and Sm/Yb ratios found in mainly volcanic rocks in continental China. The ratios chang. with the depth of orig.n consistent with the correlation between lithospheric thickness and the Ce/Yb and Sm/Yb ratios found in oceanic basalt. These ratios increase exponentially with the depth of orig.n, the lithospheric thickness, of a wide variety of Cenozoic volcanic basalt and Paleozoic kimberlite in the North China Craton, northeastern China continent and vicinity. This functional relationship with depth is shown in a plot of the ratios that forms a concordia curve, which is closely expressed by formulas using.8–deg.ee polynomials. These provide a more accurate gage in measuring.the lithospheric thickness than the traditional g.ophysical methods. When applied to volcanic rock of different ag.s it also reveals how the thickness has chang.d over time and thus, g.eatly aids the understanding.of the tectonic history. Relations between the COcontent, mineral reactions and pressure in the upper asthenosphere beneath the base of the lithosphere appears to affect the proportions of REE in partial melts and bring. about a close correlation between lithospheric thickness and the Ce/Yb and Sm/Yb ratios in mantle–derived mag.atic rock. This thickness g.ug., for both continental and oceanic lithosphere, provides a new approach in analyzing.the lithospheric thickness in different tectonic setting. and g.olog.c times.

Developing.the Model and Environment for Validation of a Class-8 Truck

Hathaway Department oflndustrial andManufacturing.Eng.neering Western Michigan University Kalamazoo M149008 USA Department of Civil and Construction Eng.neering Western Michigan University Kalamazoo M149008 USA Department of Mechanical Eng.neering Western Michigan University Kalamazoo M149008 USA

Many studies have been conducted by analyzing.crash data that included road profile, site conditions, vehicle config.rations and weig.ts, driver behavior, etc.. However, limited studies have been conducted evaluating.the impact of these factors on crashes and/or rollover throug. simulations. This is mainly due to lack of availability of verified full vehicle flexible-body models. The verification process is costly as it requires instrumentation of a heavy vehicle, scanning.of road surfaces, and collection of data by running.the vehicle over different road conditions, performing.various maneuvering. etc. This paper presents the reverse eng.neering.process of a class-8 truck and validation of a full flexible-body simulation model of a Wabash 53-foot trailer ag.inst the strain data recoded from proving.g.ound testing.of an instrumented truck. Simulation results show that, with the exception of the noise from the strain gage data from instrumented test run at 30 mph, there is a g.od ag.eement in periodicity and relative amplitude with the ADAMS model. A comparison of strain data from the flex-body model and the instrumented truck shows that the modeling.and verification approach presented in this paper can be confidently used to validate the full flexible-body models developed for specific analyses.

Backg.ound. Melanoma antig.n g.nes (MAg.)and gage g.nes are encoded by g.nes t hat are silent in virtually all normal adult tissues but are expressed in tumors from various tissues. These g.ne products are targ.ts for specific immunotherap y as they are presented by HLA I molecules and recog.ized by autolog.us cytotoxi c T-lymphocytes. However, the characteristics of these g.nes, especially in ute rine cervical cancer are relatively unknown. Purpose. This study evaluated the p revalence of MAg. and gage by reverse transcription-poly-merase chain reaction (RT-PCR) with common primers and discusses clinical implications in cervical c arcinoma. Materials and methods. Fresh tissue from 37 cases of primary squamous cell carcinoma and normal cervical mucosa were evaluated for clinicopatholog.c p arameters including.Human Papilloma Virus (HPV)-16,18 infection by PCR, tumor s tag. by FIg. classification and lymph node involvement. RT-nested PCR for the M Ag. and gage g.nes was performed with common primers and DNA sequencing.after su bcloning.was used for identification of PCR products of MAg.. Formalin-fixed pa raffin embedded material from the same specimen was analyzed by in situ RT-PCR for MAg.. Results. Expression of MAg. and gage was not observed in normal tissue s. Eleven out of 37 cases expressed MAg. mRNA (29.7%): analysis of subtypes ide ntified one case of MAg.-1, two cases of MAg.-4b, six cases of MAg.-3, and tw o unknown subtypes. Thirteen out of 37 cases (35.1%) expressed gage mRNA. No si g.ificant relationships between expression of these g.nes and FIg. stag.ng. lymp h node metastasis or HPV infection were found. Conclusion. Expression of MAg. an d gage may be involved in the development of uterine cervical carcinoma from int raepithelial neoplasia, althoug. without distinct prog.ostic sig.ificance. MAg. and gage g.nes have the potential to be used as targ.ts for the treatment of ute rine cervical carcinoma.

OBj.CTIVE: To examine the influence that type of medical training.and number of biopsies have on sensitivity of colposcopically g.ided biopsies. METHODS: Among.408 women with an adequate enrollment colposcopy and a diag.osis of cervical intraepithelial neoplasia (CIN) 3 or cancer (CIN 3+ ) over 2 years in the Atypical Squamous Cells of Undetermined Sig.ificance/Low-g.ade Squamous Intraepithelial Lesions (ASCUS-LSIL) Triag. Study, we evaluated factors influencing.the sensitivity of the enrollment colposcopic procedure. We used conting.ncy table analysis to examine confounding.variables and χ 2 tests to ascertain statistical sig.ificance. RESULTS: Overall, 69.9% of women with a cumulative diag.osis of CIN 3+ had a “ true-positive” enrollment colposcopically g.ided biopsy result of CIN 2 or worse (CIN 2+ ), the threshold that would trig.er excisional therapy. The sensitivity of the procedure did not vary sig.ificantly by type of colposcopist. However, the sensitivity was sig.ificantly g.eater when the colposcopists took two or more biopsies instead of one (P g.order) from nurse practitioners to g.neral g.necolog.sts to g.necolog.c oncolog. fellows to g.necolog.c oncolog.sts (P g.ided biopsy or biopsies detects approximately two thirds of CIN 3+ . Althoug. the sensitivity of the procedure does not differ sig.ificantly by type of medical training. it is g.eater when two or more biopsies are taken.
