We study the complexity of Geometric Graph Isomorphism, in l2 and other lp metrics: given two sets of n points A,B ⊂ Q in k-dimensional euclidean space the problem is to decide if there is a bijection π : A→ B such that for all x, y ∈ A, d(x, y) = d(π(x), π(y)), where d is the distance given by the metric. Our results are the following: • We describe algorithms for isomorphism and canonization ...

Purpose The SLE Subcommittee of the Childhood Arthritis and Rheumatology Research Alliance (CARRA) is developing standardized treatment plans for proliferative lupus nephritis (LN) in childhood-onset SLE (cSLE) which will serve as the basis for future comparative effectiveness studies. The Initial Delphi survey revealed wide variability in the treatment of LN in cSLE. This abstract decribes the...

The paper is concerned with spatial and time regularity of solutions to linear stochastic evolution equation perturbed by Lévy white noise ”obtained by subordination of a Gaussian white noise”. Sufficient conditions for spatial continuity are derived. It is also shown that solutions do not have in general cádlág modifications. General results are applied to equations with fractional Laplacian. ...

spatial patterns of soil fertility parameters, and other extrinsic factors need to be iden-tified to develop farming practices that match agricultural inputs with local crop needs. little is known about the spatial structure of yield and weed density across fields. in this study, geostatistics was used to describe and map spatial patterns of soil total nitrogen, available phosphorus, available ...

Background and Aim: In this study, we investigated the effect of immobilization stress during pregnancy on the spatial memory, anxiety-like behavior and brain BDNF level in F1 generation male NMRI mice. Materials and Methods: Twenty female pregnant mice were randomly divided into stress and control groups. The stress group received stress using a restraint cylinder (6 cm ID, 20 cm L) 60 min/da...

Nitric oxide (NO) is thought to be involved in spatial learning and memory in several brain areas such as hippocampus. This study examined the effects of post-training intrahippocampal microinjections of 1400W as a selective inducible nitric oxide synthase (iNOS) inhibitor on spatial memory, in both anesthetized and non-anesthetized situations in rats. In the present work, 4-day training trials...

A lattice L is spatial if every element of L is a join of completely join-irreducible elements of L (points), and strongly spatial if it is spatial and the minimal coverings of completely join-irreducible elements are well-behaved. Herrmann, Pickering, and Roddy proved in 1994 that every modular lattice can be embedded, within its variety, into an algebraic and spatial lattice. We extend this r...

To study the physiological and molecular mechanisms of age-related memory loss, we assessed spatial memory in C57BL/B6 mice from different age cohorts and then measured in vitro the late phase of hippocampal long-term potentiation (L-LTP). Most young mice acquired the spatial task, whereas only a minority of aged mice did. Aged mice not only made significantly more errors but also exhibited gre...

Priming for perceptual wholes and parts was examined in 4 experiments involving patterns arranged in a spatial hierarchy (D. Navon, 1977). Previous studies have demonstrated "level-specific priming" across successive trials for these patterns (L. C. Robertson, R. Egly, M. R. Lamb, & L. Kerth, 1993; L. M. Ward, 1982), and studies in neuropsychology have shown an absence of this priming effect in...

geostatistical techniques were used to describe the spatial distribution of weeds, under conventional management conditions and theirs effect on wheat biomass production over the course of one growing season (2008-2009), in a wheat (triticum aestivum l.) field at research station of shahrood university, iran. weeds seedling were identified and counted at 121 points of field based on two interva...
