Axon pruning is widely used for the refinement of neural circuits in both vertebrates and invertebrates, and may also contribute to the pathogenesis of neurodegenerative diseases. However, little is known about the cellular and molecular mechanisms of axon pruning. We use the stereotyped pruning of gamma neurons of the Drosophila mushroom bodies (MB) during metamorphosis to investigate these me...

Different mixtures of olive pomace (OP), olive mill wastewater (OMWW) and olive pruning residues (OPR) were aerobically co-composted under natural conditions. Compost temperature showed a sharp increase in the first 40 60 days, followed by a stabilization at 60°C and a decline after 150 days, whereas compost water content ranged from 50% 55% to 25% 30%. Total and selective microbial counts were...

Although the classical Blum skeleton has long been considered unstable, many have attempted to alleviate this defect through pruning. Unfortunately, these methods have an arbitrary basis, and, more importantly, they do not prevent internal structural alterations due to slight changes in an object’s boundary. The result is a relative lack of development of skeleton representations for indexing o...

Ensemble learning aims at combining several slightly different learners to construct stronger learner. Ensemble of a well selected subset of learners would outperform than ensemble of all. However, the well studied accuracy / diversity ensemble pruning framework would lead to over fit of training data, which results a target learner of relatively low generalization ability. We propose to ensemb...

The seriousness of cardiac infarction can be assessed on clinical grounds. Prolonged pain refractory to morphia, severe shock with fall of blood pressure to dangerous levels, and the early onset of cardiac failure are unequivocal signs of a severe attack. In many patients regarded as suffering from cardiac infarction there are none of these signs, and the diagnosis is based on coronary pain acc...

The problem of determining Aq(n, d), the maximum cardinality of a q-ary code of length n with minimum distance at least d, is considered in some cases where corresponding MDS codes do not exist. Slight improvements of the Singleton bound are given, including Aq(q + 2, q) q3 − 3 if q is odd, A5(7, 5) 53 − 4 and A16(18, 15) 184 − 4. © 2004 Elsevier B.V. All rights reserved.

Objective: To determine the effect of pruning on seedlings Jatropha curcas L. during nursery stage.Design/Methodology/Approach: thenursery stage, a study was carried out at CPA “Abel Santamaría” Martí municipality,Cuba. A complete randomized design used. Three treatments (T) were tested: 1) control (without pruning),2) 30 cm above soil and seedling defoliation, 3) without seedlingdefoliation. d...

Pruning a decision tree is considered by some researchers to be the most important part of tree building in noisy domains. While, there are many approaches to pruning, an alternative approach of averaging over decision trees has not received as much attention. We perform an empirical comparison of pruning with the approach of averaging over decision trees. For this comparison we use a computa-t...

Many of the pruning strategies used to remove less likely hypotheses from the search beam in large vocabulary speech recognition (LVR) systems, have a peak search space many times greater than the average search space. This paper discusses two such pruning strategies used within BT’s speech recognition architecture [1], Step pruning and Histogram pruning. Two-tier pruning is proposed as a simpl...
