A mainstay of the debates concerning the phonology-syntax interface are phenomena of external sandhi, that is, phonological alternations whose conditioning environment is across a word boundary. 1A recurrent problem in this area is the fact that it is usually impossible to motivate a purely syntactic account of such alternations. This has led to the widespread consensus that the relation betwee...

AIMS To describe the design and organisation of a voluntary regional external quality assessment (EQA) scheme in histopathology, and to record the results obtained over a three year period. METHODS A protocol is presented in which circulation of EQA slides alternated with teaching sessions. Procedures for the choice of suitable cases, evaluation of submitted diagnoses, and feedback of results...

While at school children are exposed to various types of noise including external, environmental noise and noise generated within the classroom. Previous research has shown that noise has detrimental effects upon children's performance at school, including reduced memory, motivation, and reading ability. In England and Wales, children's academic performance is assessed using standardized tests ...

An electroluminescence microscopy combined with a spectroscopy was developed to visually analyze multi-junction solar cells. Triple-junction solar cells with different conversion efficiencies were characterized by using this system. The results showed that the mechanical damages and material defects in solar cells can be clearly distinguished, indicating a high-resolution imaging. The external ...

The methods of deriving the relations describing the influence of the external electric field on thermodynamic characteristics and shape of a dielectric liquid droplet are considered. It is shown that the uniform external electric field enhances nucleation for a fixed vapor chemical potential due to decreasing the chemical potential per molecule in droplet and the work of droplet formation. The...

External cephalic version (ECV) is the manipulation of the fetus, through the maternal abdomen, to a cephalic presentation. This guideline summarises the evidence regarding the routine use of ECV for breech presentation. The rationale behind ECV is to reduce the incidence of breech presentation at term and therefore the associated risks, particularly of avoidable caesarean section. The evidence...

We applied the external noise plus attention paradigm to study attention mechanisms involved in concurrent first-order and second-order motion perception at two spatial locations. Cued to attend to one of the locations, the observer was instructed to independently judge direction of motion of either first-order (Experiment 1) or second-order (Experiment 2) motion stimuli at both locations in ev...

A reciprocating quantum refrigerator is analyzed with the intention to study the limitations imposed by external noise. In particular we focus on the behavior of the refrigerator when it approaches the absolute zero. The cooling cycle is based on the Otto cycle with a working medium constituted by an ensemble of noninteracting harmonic oscillators. The compression and expansion segments are gen...

As the incidence of angina and heart failure continue to rise, new therapeutic options will be needed to treat patients who remain symptomatic or who are intolerant to current treatment. Enhanced external counterpulsation (EECP) is a noninvasive modality being investigated in both angina and congestive heart failure patients. It has been proven to provide symptomatic benefit in angina patients,...

Adaptive back stepping control (ABC) is originally applied to a linearized model of an active magnetic bearing (AMB) system. Our control goal is to regulate the deviation of the magnetic bearing from its equilibrium position in the presence of an external disturbance and system uncertainties. Two types of ABC methods are developed on the AMB system. One is based on full state feedback, for whic...
