In this paper we show that during the retrieval process in a binary symmetric Hebb neural network, spatial localized states can be observed when the connectivity of the network is distance-dependent and when a constraint on the activity of the network is imposed, which forces different levels of activity in the retrieval and learning states. This asymmetry in the activity during the retrieval a...

Children and youth with cerebral palsy present pediatricians with complex diagnostic and therapeutic challenges. In most instances, care also requires communication and comanagement with pediatric subspecialists and pediatric surgical specialists, therapists, and community developmental and educational teams. The importance of family resilience to the patient’s wellbeing broadens the ecologic s...

The food and macronutrient intake of elite Kenyan runners was compared to recommendations for endurance athletes. Estimated energy intake (EI: 2987 +/- 293 kcal; mean +/- standard deviation) was lower than energy expenditure (EE: 3605 +/- 119 kcal; P < 0.001) and body mass (BM: 58.9 +/- 2.7 kg vs. 58.3 +/- 2.6 kg; P < 0.001) was reduced over the 7-d intense training period. Diet was high in car...

A partition of a positive integer n is a finite sequence of positive integers a1, a2, . . . , ak such that a1 + a2 + · · · + ak = n and ai+1 ≥ ai for all i. We say n is the size of the partition, ai is the ith part of the partition and we call p(n) the number of partitions of n. For instance the 11 partitions of n = 6 are 6, 15, 24, 33, 222, 123, 114, 1113, 1122, 11112 and 111111, i.e., p(6) = ...

We consider a discrete-time periodic generalized Riccati equation. We investigate a few iterative methods for computing the stabilizing solution. The first method is the Kleinman algorithm which is a special case of the classical Newton-Kantorovich procedure, the second one is a method of consistent iterations and two new Stein iterations. The proposed methods are tested and illustrated via som...

OBJECTIVES We sought to investigate the role of fibroblast growth factor (FGF)-1 during acute myocardial ischemia and reperfusion. BACKGROUND The FGFs display cardioprotective effects during ischemia and reperfusion. METHODS We investigated FGF-1–induced cardioprotection during ischemia and reperfusion and the intracellular signaling pathways responsible for these effects in an ex vivo murine s...
