Most planning problems have strong structures. They can be decomposed into subdomains with causal dependencies. The idea of exploiting the domain decomposition has motivated previous work such as hierarchical planning and factored planing. However, these algorithms require extensive backtracking and lead to few efficient general-purpose planners. On the other hand, heuristic search has been a s...

We consider the Useful Informational Energy introduced by L. Pardo [5]. Our purpose is to study the asymptotic distribution of its analogue estimator, in a random and stratified sampling, as well as its application to testing hypotheses.

Any pl-stratified pseudomanifod can be normalized preserving its intersection homology. In this paper we extend this result for any topological stratified pseudomanifold and for a family of perversities which is larger than usual. Our construction is functorial. We also give a detailed description of the normalizer’s stratification in terms of the initial stratified pseudomanifold.

This article reviews the preliminary results of a five-year Technology Innovation Challenge Grant initiative in North Dakota. A stratified sample of 72 schools was selected from the 423 schools participating. Data on the competencies of the leadership within each school (both administrators and mentors) was compared to technology integration success factors of the teachers associated with the l...

In the title compound, C(15)H(12)N(2)O(2), the seven-membered ring bearing the three methyl-ene C atoms displays a puckered conformation, with the methyl-ene C atoms deviating from the plane of the benzene ring by 0.05 (1), 0.98 (1) and 1.04 (1) Å. The phenanthroline unit is not planar; the dihedral angles between this benzene ring and the other pyridyl rings are 9.62 (4) and 9.31 (4)°. The cry...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014206511 DESCRIPTION A 57-year-old woman presented with a progressing asymmetric (left to right) weakness and wasting that spread in the next 3 months from her lower to upper limbs; she exhibited mild hyper-reflexia in all four limbs. No cognitive or sensory impairment was detected. ...

The functional expression of large-conductance (BK-type) Ca -activated K (KCa ) channels was examined in developing chick lumbar motoneurons (LMNs) between embryonic day 6 (E6) and E13 using patch-clamp recording techniques. The macroscopic KCa current of E13 LMNs is inhibited by iberiotoxin and resistant to apamin. The average macroscopic KCa density was low before E8 and increased 3.3-fold by...

BACKGROUND Although only a few frontotemporal lobar degeneration (FTLD) patients develop frank amyotrophic lateral sclerosis (ALS), motor neuron dysfunctions (MNDys) occur in a larger proportion of patients. The aim of this study is to evaluate MNDys and ALS in a sample of consecutively enrolled sporadic FTLD patients. METHODS Clinical and neurophysiological evaluations (i.e. needle electromy...
