In this note, we provide an algorithm that, starting with a Sullivan algebra gives us its minimal model. More concretely, taking as input (non-minimal) A ordered finite set of generators preserving the filtration defined on A, obtain output same rational cohomology A. This is kind modified AT-model used, in past, to compute chain contraction providing other kinds topological information such (c...

Glaucoma is a disease which affects the eye and causes blindness. It is an ophthalmologist disease characterized by an increase in Intraocular Pressure (IOP). The glaucoma usually affects the optic disc on the retina which increases the cup size. There are various parameters to identify and diagnose glaucoma. The clustering technique is introduced to detect the glaucoma from the optic disc and ...

A deformable-model based approach is presented in this paper for robust detection of optic disk and cup boundaries. Earlier work on disk boundary detection up to now could not effectively solve the problem of vessel occlusion. The method proposed here improves and extends the original snake, which is essentially a deforming-only technique, in two aspects: knowledge-based clustering and smoothin...

BACKGROUND Contact pressure of UHMWPE acetabular cup has been shown to correlate with wear in total hip replacement (THR). The aim of the present study was to test the hypotheses that the cup geometry, abduction angle, thickness and clearance can modify the stresses in cemented polyethylene cups. METHODS Acetabular cups with different geometries (Link: IP and Lubinus eccentric) were tested cy...

OBJECTIVES To explore differences in experiences of care reported in the Cancer Patient Experience Survey (CPES) between patients with cancer of unknown primary (CUP) and those with metastatic disease of known primary (non-CUP); to determine insights pertaining to the experiences of care for CUP respondents from free-text comments. DESIGN Two separate, but related, studies, involving secondar...

BACKGROUND Some nonstemmed hip systems have been developed to avoid stress shielding and aseptic loosening, which are major drawbacks of stemmed hip arthroplasty. Without the stem, the cup over the femoral head can be stabilized by anatomic fitness of the cup interior and mechanical fixation of the auxiliary screws. METHODS Using finite-element method, neck-shaped systems with two bone-cup fi...

2 Introduction It is commonplace to observe that utterances can convey more information than they explicitly encode. Indeed, the field of pragmatics has grown from the insight that speakers exploit communicative conventions in order to say more with less. Less attention has been paid to the burden this places on perceivers. Because speaker meaning is underspecified, perceivers must infer implic...

Sentences frequently convey more information than they explicitly contain. For instance, suppose a speaker uses a noun phrase (NP) modified by an adjective, as in “the tall cup.” In this situation, perceivers infer the existence of two sets of entities in the discourse: (1) a target set corresponding to the literal denotation of the expression (e.g., a tall cup), and (2) a contrast set containi...

PURPOSE In THA a sufficient primary implant stability is the precondition for successful secondary stability. Industrial foams of different densities have been used for primary stability investigations. The aim of this study was to analyse and compare the insertion behaviour of threaded and press-fit cups in vivo and ex vivo using bone substitutes with various densities. METHODS Two threaded ...
