Western Liaoning of northeastern China is world-renowned for the MesozoicJehol biota, especially for yielding many feathered dinosaurs, primitive birds, mammals and fossilangiosperm. This paper describes a complete specimen of a symmetrodont mammal with well-preservedhairs and soft tissue from the basal part of the Yixian Formation in the Sihetun area, Beipiao,western Liaoning. It is significant for understanding the morphology, osteology, phylogeny and lifehabits of Mesozoic symmetrodont mammals.

Clinician Misperceptions about the Importance of Adolescent HPV Vaccination

引用

World Journal of Vaccines 2016年第1期6卷 9-15页

作者： Martin C. Mahoney Frances G. Saad-Harfouche Christy A. Widman Annamaria Masucci Twarozek Deborah O. Erwin Elisa M. Rodriguez Department of Health Behavior Roswell Park Cancer Institute Buffalo NY USA Department of Cancer Prevention and Control Office of Cancer Health Disparities Research Roswell Park Cancer Institute Buffalo NY USA

Introduction: Adolescent HPV vaccination rates remain suboptimal. The purpose of the study was to investigate attitudes about HPV vaccine relative to other adolescent vaccines among clinical staff from primary care offices and school based clinics. Methods: We interviewed clinicians in primary care offices and school-based clinics regarding their attitudes about HPV vaccine relative to Tdap and MCV4. Results: Respondents (n = 36) included clinical staff in family medicine (47%), pediatrics (25%), obstetrics/gynecology (19%) and school-based health clinics (8%). Only 3% strongly agreed and 17% agreed that completion of HPV vaccine was more important than completion of pertussis vaccine (Tdap), while 6% strongly agreed and 33% agreed that completion of HPV vaccine was more important than completion of meningitis vaccine (MCV4). Discussion: Providing clinicians with additional information about the cancer prevention benefits of the HPV vaccine and the greater risk for HPV infection/disease relative to other vaccine preventable adolescent diseases may help to increase HPV vaccination rates among adolescents.

Chi-Square Distribution: New Derivations and Environmental Application

引用

Journal of Applied Mathematics and Physics 2019年第8期7卷 1786-1799页

作者： Thomas M. Semkow Nicole Freeman Umme-Farzana Syed Douglas K. Haines Abdul Bari Abdul J. Khan Kimi Nishikawa Adil Khan Adam G. Burn Xin Li Liang T. Chu Wadsworth Center New York State Department of Health Albany NY USA Department of Environmental Health Sciences University at Albany State University of New York Rensselaer NY USA Averill park Central School District Averill Park NY USA

We describe two new derivations of the chi-square distribution. The first derivation uses the induction method, which requires only a single integral to calculate. The second derivation uses the Laplace transform and requires minimum assumptions. The new derivations are compared with the established derivations, such as by convolution, moment generating function, and Bayesian inference. The chi-square testing has seen many applications to physics and other fields. We describe a unique version of the chi-square test where both the variance and location are tested, which is then applied to environmental data. The chi-square test is used to make a judgment whether a laboratory method is capable of detection of gross alpha and beta radioactivity in drinking water for regulatory monitoring to protect health of population. A case of a failure of the chi-square test and its amelioration are described. The chi-square test is compared to and supplemented by the t-test.
