In the context of multiple hypotheses testing, the proportion π0 of true null hypotheses among the hypotheses to test is a quantity that often plays a crucial role, although it is generally unknown. In order to obtain more powerful procedures, recent research has focused on finding ways to estimate this proportion and incorporate it in a meaningful way in multiple testing procedures, leading to...

where a = 0 or 1, are among the most famous q-series identities in partitions and combinatorics. Since their discovery the Rogers-Ramanujan identities have been proved and generalized in various ways (see [2, 4, 5, 13] and the references cited there). In [13], by adapting a method of Macdonald for calculating partial fraction expansions of symmetric formal power series, Stembridge gave an unusu...

A study of Sphaeropthalma Blake from the southwestern USA has revealed a highly autapomorphic undescribed species. This species is described here as S. tapio Pitts & Sadler, sp. nov., and is placed in a new species-group, the S. tapio species-group. This species seems to be found only at higher altitudes in southern Arizona. It is compared to other similar Sphaeropthalma species-groups and is l...

(1) The author would like to thank Mette Eriksen for conducting the searches on SciFinder. Helpful contributions on earlier versions were made by John Bailar, Carl Cranor, David Gee and David Kriebel. The goals of academic researchers may differ from those of regulatory agencies responsible for protecting the environment. Thus, research must take into account issues such as feasibility, merit a...

In the synergistic evolution of their research, educational, and clinical programs, the University of Pittsburgh (Pitt) School of Medicine (SOM) and the University of Pittsburgh Medical Center (UPMC) have followed one core principle: What is good for one is good for both. The collaboration is underpinned by UPMC's commitment to its community mission, including support for the academic and resea...

Purpose. To evaluate whether prophylactic circumferential retinal cryopexy (CRC) can prevent pseudophakic retinal detachment (PRD) development after posterior capsule rupture (PCR) during phacoemulsification. Methods. Retrospective patient chart analysis of eyes experiencing a PCR during phacoemulsification. Comparison of PRD development between eyes receiving CRC (cryo+ group) or not (cryo- gr...

The Internet is emerging as an important tool for organizations to communicate with journalists and publics. This article reports the results of a five point-in-time study of organizational use of the Internet in crisis communication. Through the lens of Rogers’ [Rogers, E. (1962/1995). Diffusion of innovations. New York: Free Press] diffusion of innovations research, the data suggest that abou...

This retrospective study aimed to evaluate, through an ad hoc 17-item tool, the Pulmonary Rehabilitation Decisional Score (PRDS), the priority access to PR prescription by respiratory specialists. The PRDS, scoring functional, clinical, disability, frailty, and participation parameters from 0 = low priority to 34 = very high priority for PR access, was retrospectively calculated on 124 speciali...

Chromosomal rearrangements involving partial deletion of the short arm of chromosome 4 and partial duplication of the short arm of chromosome 8 have been described both in Pitt-Rogers-Danks syndrome (PRDS) and WolfHirschhorn syndrome (WHS), the former being considered a milder phenotype of the latter. We describe a patient with partial deletion of chromosome 4 and partial duplication of chromos...
