Modified Cholesky algorithms: a catalog with new approaches
Given an n × n symmetric possibly indefinite matrix A, a modified Cholesky algorithm computes a factorization of the positive definite matrix A + E , where E is a correction matrix. Since the factorization is often used to compute a Newton-like downhill search direction for an optimization problem, the goals are to compute the modification without much additional cost and to keep A + E wellcond...
متن کاملInm-2: New Approaches in Cryopreservation
Cryopreservation of embryos and gametes has become an indispensible service for infertility treatment. Vitrification is now a prevalent technique for cryopreservation in assisted reproductive technology (ART) replacing, in many cases, conventional slow cooling methodology. Fertility preservation in female patients has become a very topical issue. Various malignant and nonmalignant diseases have...
متن کاملPolycythemia vera: from new, modified diagnostic criteria to new therapeutic approaches.
Polycythemia vera (PV) is a Philadelphia chromosome-negative chronic myeloproliferative neoplasm that is associated with a Janus kinase 2 (JAK2) mutation in most cases. The most recent update to the World Health Organization diagnostic criteria for PV was published in 2016. These were the modifications with the greatest effect: (1) lowering the hemoglobin threshold, allowing a diagnosis of PV a...
متن کاملNew Approaches to Analyze Gasoline Rationing
In this paper, the relation among factors in the road transportation sector from March, 2005 to March, 2011 is analyzed. Most of the previous studies have economical point of view on gasoline consumption. Here, a new approach is proposed in which different data mining techniques are used to extract meaningful relations between the aforementioned factors. The main and dependent factor is gasolin...
متن کاملNew Approaches in 3D Geomechanical Earth Modeling
In this paper two new approaches for building 3D Geomechanical Earth Model (GEM) were introduced. The first method is a hybrid of geostatistical estimators, Bayesian inference, Markov chain and Monte Carlo, which is called Model Based Geostatistics (MBG). It has utilized to achieve more accurate geomechanical model and condition the model and parameters of variogram. The second approach is the ...
