MITOCHONDRIAL DNA POLYMORPHISMS AND FERTILITY IN BEEF CATTLE

Two regions of mitochondrial DNA, D-loop and ND-5 were characterized using polymerase chain reaction – restriction fragment length polymorphism (PCR-RFLP) involving 422 beef cattle of Hereford and composite breeds from Wokalup’s research station. ANOVA models (model I, II) were used to estimate associations between molecular haplotypes and quantitative traits. The phenotypic data used were records on calving rate, defined as the mean number of live calves born over four years, while the genotypic data used were the result of PCR-RFLP analysis in both regions of mitochondrial DNA using 7 restriction enzymes. The results of the present study have provided evidence that mitochondrial polymorphisms in the D-loop and ND-5 regions are associated significantly with fertility. This is the first report of a correlation between mitochondrial polymorphism in D-loop and ND-5 on fertility in beef cattle. Key words: PCR-RFLP, bovine mitochondrial DNA, D-loop, ND-5

Universal Quantum Cloning in Cavity QED

We propose an implementation of an universal quantum cloning machine [UQCM, Hillery and Buzek, Phys. Rev. A {\bf 56}, 3446 (1997)] in a Cavity Quantum Electrodynamics (CQED) experiment. This UQCM acts on the electronic states of atoms that interact with the electromagnetic field of a high $Q$ cavity. We discuss here the specific case of the $1 \to 2$ cloning process using either a one- or a two-cavity configuration

Surface critical exponents at a uniaxial Lifshitz point

Using Monte Carlo techniques, the surface critical behaviour of three-dimensional semi-infinite ANNNI models with different surface orientations with respect to the axis of competing interactions is investigated. Special attention is thereby paid to the surface criticality at the bulk uniaxial Lifshitz point encountered in this model. The presented Monte Carlo results show that the mean-field description of semi-infinite ANNNI models is qualitatively correct. Lifshitz point surface critical exponents at the ordinary transition are found to depend on the surface orientation. At the special transition point, however, no clear dependency of the critical exponents on the surface orientation is revealed. The values of the surface critical exponents presented in this study are the first estimates available beyond mean-field theory.Comment: 10 pages, 7 figures include

'Drowning in here in his bloody sea' : exploring TV cop drama's representations of the impact of stress in modern policing

The Criminal Justice System is a part of society that is both familiar and hidden. It is familiar in that a large part of daily news and television drama is devoted to it (Carrabine, 2008; Jewkes, 2011). It is hidden in the sense that the majority of the population have little, if any, direct contact with the Criminal Justice System, meaning that the media may be a major force in shaping their views on crime and policing (Carrabine, 2008). As Reiner (2000) notes, the debate about the relationship between the media, policing, and crime has been a key feature of wider societal concerns about crime since the establishment of the modern police force. He outlines the recurring themes in post-war debates in this field. For Conservatives there has been an ongoing concern that the media is criminongenic, as it serves to undermine traditional institutions, including the police. From the viewpoint of radical criminology, the impact of the media is two-fold: it exaggerates legitimate concerns about crime and emphasises the bureaucratic and other restrictions under which the police operate (Reiner, 2000). This is seen as undermining due process and legitimatising what can be termed a ‘maverick’ approach to policing. An early example of this can be seen in Clint Eastwood’s Dirty Harry movies (Siegel, 1971) where Harry Callaghan acts as a one-man law enforcement system outside of the formal legal process, a process portrayed as corrupt, inefficient, and concerned with offenders’ rights rather than protecting victims. From a policing perspective, Reiner (2000) argues that film and TV drama creates a simplistic narrative of crime solving that is almost completely divorced from the reality of modern police work, a finding consistent with more recent work by Cummins et al., (2014)

Artificial Intelligence and Transcatheter Interventions for Structural Heart Disease: A glance at the (near) future

With innovations in therapeutic technologies and changes in population demographics, transcatheter interventions for structural heart disease have become the preferred treatment and will keep growing. Yet, a thorough clinical selection and efficient pathway from diagnosis to treatment and follow-up are mandatory. In this review we reflect on how artificial intelligence may help to improve patient selection, pre-procedural planning, procedure execution and follow-up so to establish efficient and high quality health care in an increasing number of patients

Whole genome analysis of a schistosomiasis-transmitting freshwater snail

Biomphalaria snails are instrumental in transmission of the human blood fluke Schistosoma mansoni. With the World Health Organization's goal to eliminate schistosomiasis as a global health problem by 2025, there is now renewed emphasis on snail control. Here, we characterize the genome of Biomphalaria glabrata, a lophotrochozoan protostome, and provide timely and important information on snail biology. We describe aspects of phero-perception, stress responses, immune function and regulation of gene expression that support the persistence of B. glabrata in the field and may define this species as a suitable snail host for S. mansoni. We identify several potential targets for developing novel control measures aimed at reducing snail-mediated transmission of schistosomiasis
