Abstract:

Abstract. Gross primary production (GPP), separated from flux tower measurements of net ecosystem exchange (NEE) of CO2, is used increasingly to validate process-based simulators and remote sensing-derived estimates of simulated GPP at various time steps. Proper validation should include the uncertainty associated with this separation at different time steps. This can be achieved by using a Bayesian framework. In this study, we estimated the uncertainty in GPP at half hourly time steps. We used a non-rectangular hyperbola (NRH) model to separate GPP from flux tower measurements of NEE at the S

Abstract:

Abstract The available collaborative studies for standard methods of analysis for various constituents of milk and milk products were examined in an attempt to assign specific repeatability and reproducibility precision parameters to these methods. The different collaborative assays for the primary constituents (moisture/solids, fat, protein), the nutritionally important elements (calcium, sodium, potassium, phosphorus), and miscellaneous analytes/physical constants (ash, lactose, salt, freezing point) produced different estimates of the precision parameters for the same method.

Abstract:

A high-value doctor-patient relationship is based on a set of parameters which include the interpersonal relationship between the patient and the doctor. Based on the Primary Care Assessment Survey model, measures of the interpersonal relationship are associated with communication, interpersonal care, contextual knowledge of the patient, and trust. Despite the proven value of the doctor-patient relationship, current trends indicate that the quality of these relationships is on the decline.

Abstract:

Abstract Flow cytometry is a powerful tool for diagnosis and detection of minimal residual disease (MRD) in patients with monoclonal gammopathies. Multi-parameter MRD flow analysis is more sensitive than serum immunofixation for the detection of residual disease and is as effective as PCR analysis for predicting outcome after high-dose therapy. Attaining a limit of detection of 0.01% abnormal plasma cells in every patient requires analysis of several neoplastic markers. However, basic immunophenotyping coupled with clonality assessment can be informative in many patients. This approach can als

Abstract:

High-frequency, long-duration intracortical microstimulation (HFLD-ICMS) applied to motor cortex is recognized as a useful and informative method for corticomotor mapping by evoking natural-appearing movements of the limb to consistent stable end-point positions. An important feature of these movements is that stimulation of a specific site in motor cortex evokes movement to the same spatial end point regardless of the starting position of the limb. The goal of this study was to delineate effective stimulus parameters for evoking forelimb movements to stable spatial end points from HFLD-ICMS a

Abstract:

As the distribution of pain in primary headaches suggests involvement of the trigeminal sensory pathways, trigeminal somatosensory evoked potentials (TSEP) and blink reflexes (BR) may provide important information about their functional integrity. Functional differences between symptomatic and non-symptomatic sides and between measurements during and outside attacks may be particularly informative. These tests should therefore be reproducible and should require a suitable number of patients for future studies in patients with primary, paroxysmal headaches. We performed TSEP and BR twice in 22

In particular in hierarchical testing, no quantification of effects is possible for the first tested (and most important) hypothesis after its rejection.

The splitting weights are continuous functions of the parameters. Our method is real

Abstract:

Sometimes there is interest in a dichotomized outcome indicating whether a count variable is positive or zero. Under this scenario, the application of ordinary logistic regression may result in efficiency loss, which is quantifiable under an assumed model for the counts. In such situations, a shared-parameter hurdle model is investigated for more efficient estimation of regression parameters relating to overall effects of covariates on the dichotomous outcome, while handling count data with many zeroes. One model part provides a logistic regression containing marginal log odds ratio effects of
