INTRODUCTION In the United Kingdom and Ireland more than 40% of individuals living with perinatally acquired HIV are now aged >16. Globally, increasing numbers of women with perinatally acquired HIV are becoming pregnant, but data on fertility and pregnancy outcomes is scarce. We present pregnancy outcome data for this emerging cohort. METHODS Pregnancies in diagnosed HIV-infected women in th...

P2DHMMs manage the assignment of observations to states quite well, whereas the calculation of probabilities is a great problem. To overcome some of the defects of P2DHMMs we propose the inhomogeneous P2DHMM (IP2DHMM). In contrast to some other approaches it is able to model consistently state duration and observation matrices of fixed height at no additional cost in computational load and numb...

Resource virtualization has become one of the key super-power mobile computing architecture technologies. As mobile devices and multimedia traffic have increased dramatically, the load on mobile cloud computing systems has become heavier. Under such conditions, mobile cloud system reliability becomes a challenging task. In this paper, we propose a new model using a naive Bayes classifier for hy...

The work load of the traditional calculation method safety distance check and circuit mechanics is huge inefficiency, this paper presents a set software analysis for live working, electrical mechanical parameters working transmission lines are obtained, feasibility operation analyzed, tools reasonably selected to improve efficiency it great significance reduce emergency response time, electric ...

Many large-scale online services use structured storage to persist metadata and sometimes data. The structured storage is typically provided by standard database servers such as Microsoft’s SQL Server. It is important to understand the workloads seen by these servers, both for provisioning server hardware as well as to exploit opportunities for energy savings and server consolidation. In this p...

We introduce self-interested evolutionary market agents, which act on behalf of service providers in a large decentralised system, to adaptively price their resources over time. Our agents competitively co-evolve in the live market, driving it towards the Bertrand equilibrium, the non-cooperative Nash equilibrium, at which all sellers charge their reserve price and share the market equally. We ...

The effect of wing flexibility on aerodynamic force production has emerged as a central question in insect flight research. However, physical and computational models have yielded conflicting results regarding whether wing deformations enhance or diminish flight forces. By experimentally stiffening the wings of live bumblebees, we demonstrate that wing flexibility affects aerodynamic force prod...

In this paper, we are describing methods to perform time synchronization in a network of nodes that use wireless and ad-hoc communication, are decentralized, and have limited computing capabilities. Several new results are described. Algorithms: A new synchronization algorithm (LSA – Local Selection Algorithms) is presented that achieves low-microsecond precision and jitter, that is robust unde...
