CR immersions and Lorentzian geometry Part II: A Takahashi type theorem
No full textUsing tools from Lorentzian geometry (arising 1 from the presence of the Fefferman metric) we prove a Takahashi type theorem (for a class of pseudohermitian immersions covered by connection-preserving equivariant immersions among the total spaces of the canonical circle bundles) thus relating the geometry of a pseudohermitian immersion from a strictly pseudoconvex CR manifold M into an odd dimensional
sphere, to the spectrum of the sublaplacian on M
Repatriation from the universal museum:Iyagbon's mirror as a performance of minor-universals
No full textIn 2020 Mwazulu Diyabanza of the Yanka Nku Panafrican movement demonstratively entered a series of museums in France and Belgium and stole back African art works declairing they had been looted in the first place. This act of counter appropriation sent a wave of responses from legal to artistic around Europe. One of these was orchestrated by Samson Ogiamien and the Onyrikon theatre, which the author joined in the capacity of a collaborating artist and theorist reflecting upon the various modes of counter appropriation (and minor universality) occurring in restitutions around Europe. This chapter describes Iyagbon's Mirror, the performance work that resulted
CR immersions and Lorentzian geometry Part I: pseudohermitian rigidity of CR immersions
No full textWe study the geometry of the second fundamental form of pseudohermitian immersions among nondegenerate CR manifolds. In particular we study existence and uniqueness of pseudohermitian immersions of a strictly pseudoconvex CR manifold into an odd dimensional sphere, as determined by the pseudohermitian Gauss and Weingarten equations
Evaluation of minor pathogen intramammary infection, susceptibility parameters, and somatic cell counts on the development of new intramammary infections with major mastitis pathogens
No full textMajor mastitis pathogens such as Staphylococcus aureus, Streptococcus uberis, Streptococcus dysgalactiae, and coliforms are usually considered more virulent and damaging to the udder than minor mastitis pathogens such as Corynebacterium spp. and coagulase-negative staphylococci (CNS). The current literature comprises several studies (n=38) detailing analyses with conflicting results as to whether intramammary infections (IMI) with the minor pathogens decrease, increase, or have no effect on the risk of a quarter acquiring a new IMI (NIMI) with a major pathogen. The Canadian Bovine Mastitis Research Network has a large mastitis database derived from a 2-yr data collection on a national cohort of dairy farms, and data from this initiative were used to further investigate the effect of IMI with minor pathogens on the acquisition of new major pathogen infections (defined as a culture-positive quarter sample in a quarter that had been free of that major pathogen in previous samples in the sampling period). Longitudinal milk samplings of clinically normal udders taken over several 6-wk periods as well as samples from cows pre-dry-off and postcalving were used to this end (n=80,397 quarter milk samples). The effects of CNS and Corynebacterium spp. on the major mastitis pathogens Staph. aureus, Strep. uberis, Strep. dysgalactiae, and coliform bacteria (Escherichia coli and Klebsiella spp.) were investigated using risk ratio analyses and multilevel logistic regression models. Quarter-, cow- and herd-level susceptibility parameters were also evaluated and were able to account for the increased susceptibility that exists within herds, cows and quarters, removing it from estimates for the effects of the minor pathogens. Increased quarter-level susceptibility was associated with increased risk of major pathogen NIMI for all pathogens except the coliforms. Increased somatic cell count was consistently associated with elevated risk of new major pathogen infections, but this was assumed to be a result of low sensitivity of bacteriology to diagnose major pathogen NIMI expediently and accurately. The presence of CNS in the sample 2 samplings before the occurrence of a NIMI increased the odds of experiencing a Staph. aureus NIMI 2.0 times, making the presence of CNS a risk factor for acquiring a Staph. aureus NIMI. Even with this extensive data set, power was insufficient to make a definitive statement about the effect of minor pathogen IMI on the acquisition of major pathogen NIMI. Definitively answering questions of this nature are likely to require an extremely large data set dedicated particularly to minor pathogen presence and NIMI with major pathogens
Minor spliceosome and disease
No full texttThe U12-dependent (minor) spliceosome excises a rare group of introns that are characterized by ahighly conserved 5splice site and branch point sequence. Several new congenital or somatic diseaseshave recently been associated with mutations in components of the minor spliceosome. A commontheme in these diseases is the detection of elevated levels of transcripts containing U12-type introns,of which a subset is associated with other splicing defects. Here we review the present understandingof minor spliceosome diseases, particularly those associated with the specific components of the minorspliceosome. We also present a model for interpreting the molecular-level consequences of the differentdiseases.Peer reviewe
