BACKGROUND For more effective and safer usage of antibiotics, the dosing strategy should be individualized based on the patients' characteristics, including race. The aim of this study was to investigate the population pharmacokinetic (PK) profiles of piperacillin and tazobactam in Korean patients with acute infections. MATERIALS AND METHODS At least four consecutive 2/0.25 g or 4/0.5 g doses...
Computing all critical points of a monomial on very affine variety is fundamental task in algebraic statistics, particle physics and other fields. The number known as the maximum likelihood (ML) degree. When smooth, it coincides with Euler characteristic. We introduce degeneration techniques that are inspired by soft limits CEGM theory, we answer several questions raised literature. These perta...
The phenomenon of separation or monotone likelihood is observed in the fitting process of a logistic model if the likelihood converges while at least one parameter estimate diverges to +/- infinity. Separation primarily occurs in small samples with several unbalanced and highly predictive risk factors. A procedure by Firth originally developed to reduce the bias of maximum likelihood estimates ...
Score-based approaches for computing forensic likelihood ratios are becoming more prevalent in the forensic literature. When two items of evidential value are entangled via a scorefunction, several nuances arise when attempting to model the score behavior under the competing source-level propositions. Specific assumptions must be made in order to appropriately model the numerator and denominato...
31 Abstract—This paper investigates on the low density parity-check (LDPC) decoding algorithms and the detection methods of the multiple-input multiple-output (MIMO) systems. For LDPC codes, min-sum and layered decoding algorithms are discussed, and for MIMO detection, the maximum likelihood (ML) decision based on the sphere decoding algorithm is mainly analyzed. Also, the performance of the co...
