Assume that a linear random-effects model (LRM) y = Xβ +ε = Xβ +ε with β = Aα+γ is transformed as Ty = TXβ + Tε = TXAα + TXγ + Tε by pre-multiplying a given matrix T. Estimations/predictions of the unknown parameters under the two models are not necessarily the same because the transformation matrix T occurs in the statistical inference of the transformed model. This paper presents a general al...

We motivate special database problems introduced by peer-to-peer computing and propose the Local Relational Model (LRM) to solve some of them. As well, we summarize a formalization of LRM, present an architecture for a prototype implementation, and discuss open research questions.

OBJECTIVE To evaluate the respiratory and hemodynamic changes during lung recruitment maneuvering (LRM) through stepwise increases and decreases in PEEP level. DESIGN AND SETTING A retrospective study in a 17-bed ICU was carried out. PATIENTS Twenty-one patients with acute respiratory failure and bilateral pulmonary infiltration. INTERVENTION LRM was carried out, consisting of stepwise in...

Background Limited resources warrant investigating models for predicting which stroke tissue-type plasminogen activator (tPA) patients benefit from admission to neurologic intensive care unit (neuroICU). Methods This model classifies patients who on day 1 of their ICU admission are predicted to receive one or more of 30 subsequent active life supporting treatments. Two groups of patients were...

The Leiden ranking methodology (LRM), also known as the crown indicator, is a quantitative method for evaluating the research quality of a research group or department based on the citations received by the group in comparison to averages for the field. There have been a number of applications but these have mainly been in the hard sciences where the data on citations, provided by the ISI Web o...

BACKGROUND & AIMS Hepatitis B surface antigen (HBsAg) seroclearance and seroconversion are regarded as favorable outcomes of chronic hepatitis B (CHB). This study aimed to develop artificial neural networks (ANNs) that could accurately predict HBsAg seroclearance or seroconversion on the basis of available serum variables. METHODS Data from 203 untreated, HBeAg-negative CHB patients with spon...

1. The effect of mechanical vibration on active tension in an echinoderm somatic smooth muscle was studied using the longitudinal retractor muscle (LRM) of a sea cucumber Stichopus japonicus. 2. The steady contracture tension in LRM fibres maximally activated with 10(-3) mol l-1 acetylcholine (ACh) was reduced by vibrations (peak-to-peak amplitude, 0.5­2.5 % of l0, where l0 is the slack len...

Educational metadata can significantly assist the effective retrieval of educational resources. Currently, there are a number of tools for educational metadata authoring, facilitating the manipulation of educational metadata files. This paper outlines the requirements, and proposes an architecture for the development of a compete LRM management system which go beyond metadata authoring, support...
