Evaluation of a risk index for advanced proximal neoplasia of the colon

Gastrointestinal Endoscopy, 2015
A clinical risk index that uses distal colorectal findings at flexible sigmoidoscopy (FS) in conjunction with easily determined risk factors for advanced proximal neoplasia (APN) may be useful for tailoring or prioritizing screening with colonoscopy.To conduct an external evaluation of a previously published risk index in a large, well-characterized ...

Air pollution, surrounding green, road proximity and Parkinson's disease: a prospective cohort study.

Environmental Research, 2021
BACKGROUND Though growing evidence has linked air pollution to Parkinson's disease (PD), the results remain inconsistent. Less is known about the relevance of road proximity and surrounding green.

Revisiting the Index Construction of Proximity Graph-Based Approximate Nearest Neighbor Search

Proceedings of the VLDB Endowment
Proximity graphs (PG) have gained increasing popularity as the state-of-the-art solutions to k -approximate nearest neighbor ( k -ANN) search on high-dimensional data, which serves as a fundamental function in various fields, e.g., retrieval ...

THE OSCILLOMETRIC INDEX PROXIMAL TO VASCULAR OCCLUSION

Journal of the American Medical Association, 1932
To the Editor: —In reviewing oscillometric curves taken at various levels in cases of thrombo-angiitis obliterans as well as in cases of peripheral thromboses and emboli, and comparing these readings at corresponding levels in the unaffected limb, an interesting observation was made. It was noted that the oscillometric index at the point just proximal

Estimating Proximity of Metric Ball Regions for Multimedia Data Indexing

2000
The problem of defining and computing proximity of regions constraining objects from generic metric spaces is investigated. Approximate, computationally fast, approach is developed for pairs of metric ball regions, which covers the needs of current systems for processing data through distances.

On the use of proximity indexes for isolated word recognition

2013 IEEE International Autumn Meeting on Power Electronics and Computing (ROPEC), 2013
An isolated word recognition system with a small dictionary may perform sequencial search, that is, compare the query utterance with each and every single one in the dictionary. However, when dealing with dictionaries made out of thousands of words, sequencial search is no longer a valid strategy since we would end up with such a slow recognition ...

Proximity of supermarkets is positively associated with diet quality index for pregnancy

Preventive Medicine, 2004
To investigate the association between distance to the closest supermarket and a composite measure of diet, the diet quality index for pregnancy (DQI-P) was constructed.Data from the Pregnancy, Infection and Nutrition (PIN) cohort, a prospective study of determinants of preterm birth, were analyzed.

Indexing inexact proximity search with distance regression in pivot space

Proceedings of the Third International Conference on SImilarity Search and APplications, 2010
We introduce an inexact indexing scheme where, at index building time, training queries drawn from the database are used to fit one linear regression model for each object to be indexed. The response variable is the distance from the object to the query. The predictor variables are the distances from the query to each of a set of pivot objects.
