Appearances can deceive: even brave hearts can fail.
The enigma faces us every day and we still do not know how to define or manage it. Patients develop the typical signs and symptoms of heart failure although they apparently have “normal” left ventricular systolic function. The syndrome occurs both acutely and chronically and is responsible for approximately half of the heart failure epidemic.1 The terminology is the subject of debate. There is ...
متن کاملCan Broken Multicore Hardware be Mended?
A suggestion is made for mending multicore hardware, which has been diagnosed as broken. 1. THE MULTICORE ERA IS A CONSEQUENCE OF THE STALLING OF THE SINGLE-THREAD PERFORMANCE The multiand many-core (MC) era we have reached was triggered after the beginning of the century by the stalling of single-processor performance. Technology allowed more transistors to be placed on a die, but they could n...
متن کاملWhen QCD strings can break ∗
Most of the observed properties of the string breaking in lattice gauge models in presence of charged dynamical matter can be simply understood in terms of a topological property of the loop expansion in the underlying string description of confinement. Similar considerations apply also to the breaking of the adjoint string. The naive string picture of quark confinement is very simple: in the c...
متن کاملThe determinants of commercialisation and break-even times of innovations
Successful innovation is typically defined at the firm level where market shares, productivity, or profitability is taken as an indicator of success. Nonetheless, firms are simultaneously involved in many innovation development projects with varying success. This paper defines the success of innovations through the time taken for the innovations to reach commercialisation and the point of break...
متن کاملA Break-Even Formulation for Evaluating Branch Predictor Energy Efficiency
Recent work has demonstrated that a better branch predictor can increase the energy-efficiency of the system, even if the new predictor consumes more energy. Consequently, understanding the tradeoff between reduced misspeculation, execution time, and increased power spent within a branch predictor is critical. This paper proposes a simple, effective metric for evaluating the tradeoff between pr...
