Abstract Context Although cholecystectomy is a widely performed procedure, postoperative readmissions place heavy burden on healthcare facilities. Aims This study assesses the incidence, causes and of 30-day after in tertiary UK center. Settings Design University Hospital, Retrospective Cohort Study. Methods Material Information was obtained from our prospectively maintained database hospital’s...

PURPOSE Regorafenib, an oral multi-targeted tyrosine kinase inhibitor, is considered the new standard of care in patients with chemotherapy-refractory colorectal cancers (CRCs). However, there are no data on this drug in Korean patients. MATERIALS AND METHODS We evaluated patients who received oral regorafenib 160 mg once daily during the first 3 weeks of each 4-week cycle between August 2013...

We develop the theoretical foundation of a new representation of real numbers based on the in nite composition of linear fractional transformations (lft), equivalently the in nite product of matrices, with non-negative coe cients. Any rational interval in the one point compacti cation of the real line, represented by the unit circle S1, is expressed as the image of the base interval [0;1] under...

This paper is one of two joint papers, each presenting and utilizing a different representation of a feedforward neural network for controller design. Here a neural state-space model is transformed into a linear fractional transformation (LFT) representation to obtain a discrete-time quasi-linear parameter-varying (LPV) model of a nonlinear plant, whereas in the joint paper (Abbas and Werner [2...

We develop the theoretical foundation of a new representation of real numbers based on the innnite composition of linear fractional transformations (lft), equivalently the innnite product of matrices, with non-negative coeecients. Any rational interval in the one point compactiication of the real line, represented by the unit circle S 1 , is expressed as the image of the base interval 0; 1] und...

In this paper, a new chaos-based partial image encryption scheme based on Substitution-boxes (S-box) constructed by chaotic system and Linear Fractional Transform (LFT) is proposed. It encrypts only the requisite parts of the sensitive information in Lifting-Wavelet Transform (LWT) frequency domain based on hybrid of chaotic maps and a new S-box. In the proposed encryption scheme, the character...

Liver toxicity is a recognized adverse event associated with small molecule tyrosine kinase inhibitors (TKIs). Electronic Medical Record (EMR) databases offer the most precise data to investigate the rate of liver function test (LFT) elevations; however, they can be limited in sample size and costly to access and analyze. Health insurance claims databases often contain larger samples sizes but ...

BACKGROUND Acute heart failure (AHF) is defined as the new onset or recurrence of gradual or rapidly worsening signs and symptoms of heart failure, requiring urgent or emergent therapy. OBJECTIVES This study attempts to assess the association of liver function tests (LFT) and uric acid level with in hospital outcome and echocardiography parameters, in patients with acute decompensated heart f...
