Brief Report: Cumulative Incidence of Autism Spectrum Disorder Before School Entry in a Thoroughly Screened Population.

The present study aimed to identify the cumulative incidence of autism spectrum disorder (ASD) in a thoroughly screened population and to examine the behavioral and motor characteristics observed in children with ASD at the age of 18 months. Subjects were 1067 children who underwent a screening assessment for ASD at the routine 18-months health checkup. By the age of 6 years, 3.

Pressure response of three-dimensional cyanide-bridged bimetallic magnets.

Effects of pressure on the structures and magnetic properties of three types of 3-D cyanide-bridged bimetallic coordination polymer magnets, MnIICrIII ferrimagnet [Mn(en)]3[Cr(CN)6]2.4H2O (1; en = ethylenediamine), NiIICrIII ferromagnet [Ni(dipn)]3[Cr(CN)6]2.3H2O (2; dipn = N,N-di(3-aminopropyl)amine), and NiIIFeIII ferromagnet [Ni(dipn)]2[Ni(dipn)(H2O)][Fe(CN)6]2.

Interpenetrated three-dimensional MnIIMIII ferrimagnets, [Mn(4dmap)4]3[M(CN)6]2.10 H2O (M=Cr, Mn): structures, magnetic properties, and pressure-responsive magnetic modulation.

Two novel cyanide-bridged ferrimagnets, [Mn(4dmap)(4)](3)[M(CN)(6)](2)- 10 H(2)O (4dmap=4-dimethylaminopyridine, M=Cr (1) and Mn (2)), have been prepared from the reaction of MnCl(2)4 H(2)O, a monodentate coligand (4dmap), with K(3)[M(CN)(6)]. X-ray crystallographic results show that these are isomorphous, and form a unique twofold interpenetrated three-dimensional framework with a triconnected 6.10(2) net.

A flexible coordination polymer crystal providing reversible structural and magnetic conversions.

Structural flexibility is a remarkable characteristic of coordination polymers and significant for the attainment of environmental responsivity. We have prepared a 2D cyanide-bridged MnIICrIII coordination polymer, [Mn(NNdmenH)(H2O)][Cr(CN)6].H2O (1; NNdmen = N,N-dimethylethylenediamine), with sophisticatedly arranged removable water coligands.

A three-dimensional ferromagnet, [Ni(dipn)]3[Cr(CN)6]2.3H2O (dipn = dipropylene triamine), based on a cubic Cr8Ni12 unit.

The combination of Ni2+, dipropylenetriamine (dipn), and [Cr(CN)6]3- affords the cyanide-bridged bimetallic assembly, [Ni(dipn)]3[Cr(CN)6]2.3H2O (1). This compound crystallizes in cubic space group Pa, with a = b = c = 20.

Diversity in magnetic properties of 3D isomorphous networks of Co(II) and Mn(II) constructed by napthalene-1,4-dicarboxylate.

Two novel 3D isomorphous organic-inorganic hybrid frameworks, [M(1,4-napdc)]n ( M = Co(II), and Mn(II), ; 1,4-napdcH2 = napthalene-1,4-dicarboxylic acid) have been hydrothermally synthesized and structurally characterized, and the magnetic results exhibit metamagnetic behaviour (TC = 5.5 K), and a weak antiferromagnetic interaction, which are structurally correlated.
