OBJECTIVE The incidence of surgical site infection (SSI) after hysterectomy ranges widely from 2% to 21%. A specific risk stratification index could help to predict more accurately the risk of incisional SSI following abdominal hysterectomy and would help determine the reasons for the wide range of reported SSI rates in individual studies. To increase our understanding of the risk factors neede...

Fisher information, which lies at the heart of parameter estimation theory, was recently found to have a close relation with multipartite entanglement L. Pezzé and A. Smerzi, Phys. Rev. Lett. 102, 100401 2009 . We use Fisher information to distinguish and characterize behaviors of ground state of the Lipkin-Meskhov-Glick model, which displays a second-order quantum phase transition between the ...

Speech audiometric scores were compared across the age range from 50 to 90 years in 137 subjects selected in such a way that average audiometric thresholds were matched across four age groups. Thus any age-related changes in speech audiometric scores could not be attributed to age-related differences in peripheral hearing sensitivity. Four speech audiometric measures were studied; phonemically-...

where λ ∈ IR denotes the adjoint variable and μ is the multiplier for the control-state constraint. For this control problem, second–order sufficient conditions, sensitivity analysis and real– time control techniques have been extensively studied in the literature under the assumption that the strict Legendre condition Huu[t] ≥ cIm , c > 0, holds; c.f., e.g., Dontchev, Hager [3], Malanowski, Ma...

To investigate the influence of the neurological level of injury in bone mineral content (BMC) and mechanical properties, lean mass (LM), and fat mass (FM) among paraplegics with a similar duration of paralysis (DOP), we separated 30 paraplegics into group A (15 men, high-level paraplegia) and group B (15 men, low-level paraplegia) and compared them with group C (33 men, nondisabled). In all su...

The Fisher information matrix determines how much information a measurement brings about the parameters that index the underlying probability distribution for the measurement. In this paper we assume that the parameters structure the mean value vector in a multivariate normal distribution. The Fisher matrix is. then a Gramian constructed from the sensitivity vectors that characterize the first-...
