Control and Filtering for Discrete Linear Repetitive Processes with H infty and ell 2--ell infty Performance
No full textRepetitive processes are characterized by a series of sweeps, termed passes, through a set of dynamics defined over a finite duration known as the pass length. On each pass an output, termed the pass profile, is produced which acts as a forcing function on, and hence contributes to, the dynamics of the next pass profile. This can lead to oscillations which increase in amplitude in the pass to pass direction and cannot be controlled by standard control laws. Here we give new results on the design of physically based control laws for the sub-class of so-called discrete linear repetitive processes which arise in applications areas such as iterative learning control. The main contribution is to show how control law design can be undertaken within the framework of a general robust filtering problem with guaranteed levels of performance. In particular, we develop algorithms for the design of an H? and dynamic output feedback controller and filter which guarantees that the resulting controlled (filtering error) process, respectively, is stable along the pass and has prescribed disturbance attenuation performance as measured by and – norms

REDUCTION OF THE VIBRATION-ROTATION-LAM HAMILTONIAN
No full textAuthor Institution: Department of Physics, Texas Tech UniversityThe vibration-rotation-LAM Hamiltonian requires two independent separation conditions to reduce the Coriolis interaction and the vibration-LAM kinetic energy interaction. In the limit of the LAM approaching a SAM, the effective vibration-rotation Hamiltonian and/or energy must reduce to the usual vibration-rotation Hamiltonian when no internal motion is a LAM. We show how to perform this reduction, especially as it relates to the T-and R-transformations and the normal coordinate transformation
Utility of novel diagnostic tests for tuberculosis using human urine
No full textIncludes abstract.Includes bibliographical references.Two thirds of new TB cases in sub-Saharan Africa are HIV coinfected. HIV-TB co-infection increases the incidence of extra-pulmonary, sputum smear-negative and sputum-scarce TB. In these vulnerable patientgroups with high mortality rates, sputum-based diagnostic tools are unhelpful. Urine-based diagnostics offer an attractive, easily available alternative for rapid diagnosis. We evaluated the point-of-care urine LAM strip test (Determine TB LAM Ag test, Alere) and urine-based Xpert MTB/RIF for TB diagnosis in two patient cohorts with high HIV prevalence. A spot urine sample was collected from two cohorts of persons with suspected TB. The first cohort consisted of ambulatory primary care clinic patients suspected of having TB (group 1) whilst the second comprised hospitalised patients with suspected HIV co-infection (group 2). The urine LAM ELISA, LAM strip test and Xpert MTB/RIF were performed according to the manufacturer’s instructions. In addition, the effects of using an alternative ‘rulein’ cut-point for the urine LAM strip test and a pelleted (2-10ml) urine sample for Xpert MTB/RIF testing on diagnostic accuracy and inter-reader reliability was assessed. The diagnostic reference standard was M. tuberculosis culture positivity

Postoperative day one serum alanine aminotransferase does not predict patient morbidity and mortality after elective liver resection in non-cirrhotic patients
No full textSerum aminotransferases have been used as surrogate markers for liver ischemia-reperfusion injury that follows liver surgery. Some studies have suggested that rises in serum alanine aminotransferase (ALT) correlate with patient outcome after liver resection. We assessed whether postoperative day 1 (POD 1) ALT could be used to predict patient morbidity and mortality following liver resection. We reviewed our prospectively held database and included consecutive adult patients undergoing elective liver resection in our institution between January 2013 and December 2014. Primary outcome assessed was correlation of POD 1 ALT with patient's morbidity and mortality. We also assessed whether concurrent radiofrequency ablation, neoadjuvant chemotherapy and use of the Pringle maneuver significantly affected the level of POD 1 ALT. A total of 110 liver resections were included in the study. The overall in-hospital patient morbidity and mortality were 31.8% and 0.9%, respectively. The median level of POD 1 ALT was 275 IU/L. No correlation was found between POD 1 serum ALT levels and patient morbidity after elective liver resection, whilst correlation with mortality was not possible because of the low number of mortalities. Patients undergoing concurrent radiofrequency ablation were noted to have an increased level of POD 1 serum ALT but not those given neoadjuvant chemotherapy and those in whom the Pringle maneuver was used. Our study demonstrates POD 1 serum ALT does not correlate with patient morbidity after elective liver resection.</p
