An original system of grading of the corneal endothelial specular reflection, as assessed with a Haag-Streit 900 slit-lamp biomicroscope, has been shown to have a very highly significant relation to the endothelial cell density measured by contact specular photomicroscopy. The grading, though subjective and therefore not a substitute for the detailed record of photomicroscopy, is readily applic...

As regards the influencing radius and influencing area of agricultural land grading factor, the agricultural land grading regulation simply use decay method or exponential method to determine their values, what is more, it only considers the natural factors of land grading and takes little account of socioeconomic factors. So, there are some defects in agricultural land grading. To address abov...

Assessment is an integral part of learning and plays a significant role in education. Adaptive testing is a form assessment in which the tests are tailored to the individual’s ability. This paper presents an adaptive assessment system realized in PHP and MYSQL. The motivation was to investigate the techniques for the improvement of student assessment. The paper also focuses on adaptive grading ...

Peer-grading is widely believed to be an inexpensive and scalable way to assess students in large classroom settings. In this paper, we propose calibrated self-grading as a more efficient alternative to peer grading. For self-grading, students assign themselves a grade that they think they deserve via an incentive-compatible mechanism that elicits maximally truthful judgements of performance. W...

Heegaard Floer homology, first introduced by P. Ozsváth and Z. Szabó in [OS04b], associates to a 3-manifold Y a family of relatively graded abelian groups HF (Y, t), indexed by Spin structures t on Y . In the case that Y is a rational homology sphere, Ozsváth and Szabó lift the relative Z-grading to an absolute Q-grading [OS06]. This induces a relative Q-grading on ⊕ t∈Spin(Y ) HF (Y, t). In th...

We specify a model for the conceptual interpretation of relative adjectives (like “big”), which covers a crucial aspect of the underlying comprehension process – the comparison to a norm that is associated with a comparison class. Building on an elaborate domain ontology and knowledge about intercorrelations, comparison classes are dynamically created depending on the context in which adjectiva...

Background and Purpose—The accuracy of carotid ultrasound has not been well established in predicting intrastent restenosis (ISR) after carotid artery stenting (CAS). The aim of this study is to determine different degrees of ISR using ultrasound velocity criteria compared to percentage of stenosis at angiography. Methods—This is a 6-year prospective study. After CAS procedure, each patient und...
