Purpose: previous studies have suggested that thigh muscle imbalance may be a risk factor for knee injury. The Present study aimed to compare Hamstring-to-Quadriceps (H:Q) Ratio and dynamic stability between the two lower limbs of elderly people. Methods: This was a correlational study and by nonprobability sampling 19 healthy community doweling elderly (age=65.93±3.53 yrs.) p...

In recent years, researchers have been dedicated to the study of underactuated manipulators which have more joints than control actuators. In previous works, one always assumes that there is enough dynamic coupling between the active and the passive joints of the manipulator, for it to be possible to control the position of the passive joints via the dynamic coupling. In this work, the authors ...

The classical minimal model (MM) index of insulin sensitivity, S(I), does not account for how fast or slow insulin action takes place. In a recent work, we proposed a new dynamic insulin sensitivity index, S(I)(D), which is able to take into account the dynamics of insulin action as well. The new index is a function of two MM parameters, namely S(I) and p(2), the latter parameter governing the ...

The majority of data sets contain observations that do not conform to the structure followed by the rest of the data. These observations, known as outliers, can be found using a multitude of statistical and non-statistical methods. This paper highlights a generalized system built, specifically for price index surveys, which analysts can use to test different outlier detection methods. It also d...

E cient text indexing data structures have enabled large-scale genomic sequence analysis and are used to help solve problems ranging from assembly to read mapping. However, these data structures typically assume that the underlying reference text is static and will not change over the course of the queries being made. Some progress has been made in exploring how certain text indices, like the s...

In this paper we present a modification of a technique by Chiba and Nishizeki [Chiba and Nishizeki: Arboricity and Subgraph Listing Algorithms, SIAM J. Comput. 14(1), pp. 210–223 (1985)]. Based on it, we design a data structure suitable for dynamic graph algorithms. We employ the data structure to formulate new algorithms for several problems, including counting subgraphs of four vertices, reco...

Similarity search is a popular paradigm in advanced database applications. In content based image retrieval (CBIR) for example, images are transformed into feature vectors, which are then used for similarity search via k-nearest-neighbor (k-NN) queries in the feature vector space. Clustering by building a disk resident index is one method to speed up the processing of k-NN queries. In the case ...

In this paper we revisit the dynamic dictionary matching problem, which asks for an index for a set of patterns P1, P2, . . . , Pk that can support the following query and update operations efficiently. Given a query text T , we want to find all the occurrences of of these patterns; furthermore, as the set of patterns may change over time, we also want to insert or delete a pattern. The major c...
