Grover's search with faults on some marked elements

Grover's algorithm is a quantum query algorithm solving the unstructured search problem of size $N$ using $O(\sqrt{N})$ queries. It provides a significant speed-up over any classical algorithm \cite{Gro96}. The running time of the algorithm, however, is very sensitive to errors in queries. It is known that if query may fail (report all marked elements as unmarked) the algorithm needs $\Omega(N)$ queries to find a marked element \cite{RS08}. \cite{AB+13} have proved the same result for the model where each marked element has its own probability to be reported as unmarked. We study the behavior of Grover's algorithm in the model where the search space contains both faulty and non-faulty marked elements. We show that in this setting it is indeed possible to find one of non-faulty marked items in $O(\sqrt{N})$ queries. We also analyze the limiting behavior of the algorithm for a large number of steps and show the existence and the structure of limiting state $\rho_{lim}$.Comment: 17 pages, 6 figure

Tissue Cytokine Responses in Canine Visceral Leishmaniasis

To elucidate the local tissue cytokine response of dogs infected with Leishmania chagasi, cytokine mRNA levels were measured in bone marrow aspirates from 27 naturally infected dogs from Brazil and were compared with those from 5 uninfected control animals. Interferon-γ mRNA accumulation was enhanced in infected dogs and was positively correlated with humoral (IgG1) but not with lymphoproliferative responses to Leishmania antigen in infected dogs. Increased accumulation of mRNA for interleukin (IL)4, IL-10, and IL-18 was not observed in infected dogs, and mRNA for these cytokines did not correlate with antibody or proliferative responses. However, infected dogs with detectable IL-4 mRNA had significantly more severe symptoms. IL-13 mRNA was not detectable in either control or infected dogs. These data suggest that clinical symptoms are not due to a deficiency in interferon-γ production. However, in contrast to its role in human visceral leishmaniasis, IL-10 may not play a key immunosuppressive role in dogs

Factors that predict fertility desires for people living with HIV infection at a support and treatment centre in Kabale, Uganda

<p>Abstract</p> <p>Background</p> <p>Studies from different contexts worldwide indicate that HIV positive patients manifest high-risk sexual behavior characterized by fertility intentions, multiple sexual partners, non-use of contraceptives and non-disclosure of HIV status to their sex partners. The objective was to analyze fertility desires among persons living with HIV at a treatment centre in Kabale Hospital, Southwestern Uganda.</p> <p>Methods</p> <p>From January to August 2009, we interviewed 400 HIV positive patients seeking care using an interviewer-administered questionnaire. We assessed socio-demographic variables, reproductive history, sexuality and fertility desires. At bivariate and multivariate analysis, characteristics of participants who reported or did not report desire to have a child in the near future were compared.</p> <p>Results</p> <p>Of the 400 respondents, (25.3%) were male, 47.3% were aged 25-34 years, over 85% were currently married or had ever been married, and the 62% had primary level of education or less. Over 17% had produced a child since the HIV diagnosis was made, and 28.6% reported that they would like to have a child in the near future. Age of the respondent, being single (versus being ever-married) and whether any of the respondents' children had died were inversely associated with fertility intentions.</p> <p>Conclusion</p> <p>Factors inversely associated with fertility intentions were age of the respondent, marital status and whether any of the respondents' children had died. Use of antiretroviral therapy was not associated with fertility intentions.</p

The Anxious *Double: Twins in Plays of the 1970s, 1980s, and 1990s.

Twin characters have consistently appeared in dramatic literature throughout history. Playwrights from Shakespeare to Goldoni have employed twins in works which usually rely upon the device of mistaken identity. However, twin characters who have appeared in plays of the last thirty years have been employed with more weighty intentions. This dissertation analyzes recent playwrights\u27 portrayals of twins and the playwrights\u27 detailed explorations of the anxieties which drive the twins\u27 relationships with each other and society. Recent playwrights have also employed twins to symbolize fears peripheral to the phenomenon of twins: anxieties which plagued these three decades play heavily into these works, including tensions in the aftermath of the Vietnam War and the civil rights movements, concerns over the stewardship of our country\u27s prosperity, as well as the deterioration of the family unit. Conpersonas (1974) by Paul Stephen Lim and Corpse! (1985) by Gerald Moon each toy with twins\u27 entangled identities, thereby preying upon postmodern fears concerning fragmented selfhood. Marina Carr\u27s Portia Coughlan (1996) and Mark Handley\u27s Idioglossia (1987) each explore the intimacy of the twin bond and use this bond to highlight the society member\u27s fear of being abandoned and falling prey to loneliness. The Wedding of the Siamese Twins (1984) by Burton Cohen and Side Show (1996) by Bill Russell and Henry Krieger capitalize upon America\u27s guilt concerning its prosperity, which society may view as being gained by the exploitation of other countries and her countrymen. These plays each feature as protagonists conjoined twins who are victims of society\u27s exploitation while Philip Ridley exploits his twin protagonists\u27 fears to create his horrific play, The Pitchfork Disney (1991). The audiences\u27 and critics\u27 reception of these plays confirms Rene Girard\u27s theory of scapegoating: twin characters today have replaced groups such as African-Americans and women as the other and are being used as society\u27s scapegoats. These playwrights suggest that twins are somehow responsible for the tensions presented in these works, and the audience members viewing these productions ritually slay twins on stage to vicariously experience violence and transport evil away from the community via these twin scapegoats

Genetic screening for mutants with altered seminal root numbers in hexaploid wheat using a high-throughput root phenotyping platform

Roots are the main channel for water and nutrient uptake in plants. Optimization of root architecture provides a viable strategy to improve nutrient and water uptake efficiency and maintain crop productivity under water-limiting and nutrient-poor conditions. We know little, however, about the genetic control of root development in wheat, a crop supplying 20% of global calorie and protein intake. To improve our understanding of the genetic control of seminal root development in wheat, we conducted a high-throughput screen for variation in seminal root number using an exome-sequenced mutant population derived from the hexaploid wheat cultivar Cadenza. The screen identified seven independent mutants with homozygous and stably altered seminal root number phenotypes. One mutant, Cadenza0900, displays a recessive extra seminal root number phenotype, while six mutants (Cadenza0062, Cadenza0369, Cadenza0393, Cadenza0465, Cadenza0818 and Cadenza1273) show lower seminal root number phenotypes most likely originating from defects in the formation and activation of seminal root primordia. Segregation analysis in F2 populations suggest that the phenotype of Cadenza0900 is controlled by multiple loci whereas the Cadenza0062 phenotype fits a 3:1 mutant:wild-type segregation ratio characteristic of dominant single gene action. This work highlights the potential to use the sequenced wheat mutant population as a forward genetic resource to uncover novel variation in agronomic traits, such as seminal root architecture
