A consistent approach to the description on the structures of metal-organic frameworks (MOFs) and related materials are studied in terms of their underlying nets for cases in which these nets have more than two kinds of vertices. For MOFs formed from polytopic linkers, identifying both the basic net in which the linker is considered as a single node and the derived net in which branch points are identified explicitly, is recommended. The intrinsic symmetry of the crystal is that of the derived net, which may be lower than that of the basic net. The net gwg, derived from cds, is an example in which a tetragonal basic net has only a monoclinic derived net of minimal transitivity. Structures with different derived nets that may have the same symmetry can be differentiated. The basic nets with transitivity 3 2 (type iv of section 7) are particularly important in this regard. Several MOFs have been constructed using an octatopic linker with symmetrical shapes.

Prenatal stress is a risk factor for several psychiatric disorders in which inhibitory neuron pathology is implicated. A growing body of research demonstrates that inhibitory circuitry in the brain is directly and persistently affected by prenatal stress. This review synthesizes research that explores how this early developmental risk factor impacts inhibitory neurons and how these findings intersect with research on risk factors and inhibitory neuron pathophysiology in schizophrenia, anxiety, autism and Tourette syndrome. The specific impact of prenatal stress on inhibitory neurons, particularly developmental mechanisms, may elucidate further the pathophysiology of these disorders. © 2014 Macmillan Publishers Limited.

The pig is one of the main hosts of influenza A viruses and plays important roles in shaping the current influenza ecology. The occurrence of the 2009 H1N1 pandemic influenza virus demonstrated that pigs could independently facilitate the genesis of a pandemic influenza strain. Genetic analyses revealed that this virus was derived by reassortment between at least two parent swine influenza viruses (SIV), from the northern American triple reassortant H1N2 (TR) and European avian-like H1N1 (EA) lineages. The movement of live pigs between different continents and subsequent virus establishment are preconditions for such a reassortment event to occur. Asia, especially China, has the largest human and pig populations in the world, and seems to be the only region frequently importing pigs from other continents. Virological surveillance revealed that not only classical swine H1N1 (CS), and human-origin H3N2 viruses circulated, but all of the EA, TR and their reassortant variants were introduced into and co-circulated in pigs in this region. Understanding the long-term evolution and history of SIV in Asia would provide insights into the emergence of influenza viruses with epidemic potential in swine and humans.

This paper proposes a novel chaos-based image encryption scheme with an efficient permutation-diffusion mechanism, in which permuting the positions of image pixels incorporates with changing the gray values of image pixels to confuse the relationship between cipher-image and plain-image. In the permutation process, a generalized Arnold map is utilized to generate one chaotic orbit used to get two index order sequences for the permutation of image pixel positions; in the diffusion process, a generalized Arnold map and a generalized Bernoulli shift map are employed to yield two pseudo-random gray value sequences for a two-way diffusion of gray values. The yielded gray value sequences are not only sensitive to the control parameters and initial conditions of the considered chaotic maps, but also strongly depend on the plain-image processed, therefore the proposed scheme can resist statistical attack, differential attack, known-plaintext as well as chosen-plaintext attack. Experimental results are carried out with detailed analysis to demonstrate that the proposed image encryption scheme possesses large key space to resist brute-force attack as well. © 2011 Elsevier B.V.

By taking the Delta robot as the object of study, this paper presents the methodology of the dynamic optimum design of a three translational degrees of freedom parallel robot while considering anisotropic property. Taking the acceleration, velocity, and gravity components into account, the torque and power indices are adopted as the objective functions for the dynamic optimum design. The physical meanings of the objective functions are the maximum input torque and power of the actuating joints when the moving platform translates with assigned acceleration and velocity. The transmission angles, the determinant of the direct kinematic Jacobian matrix, the ratio of the machine volume to that of the desired workspace, and the difference between the radius of the base platform and the radius of the moving platform are adopted as the constraints for the dynamic optimum design in order to make the Delta robot have a good transmission behavior between the links, keep far away from the direct kinematic singular configuration, not to be a very tall and slender configuration, achieve the desired performance without large dimension and big building cost. The examples of the dynamic optimum design of the Delta robot based on the torque and power indices are presented in the simulation while considering the requirements of the maximum acceleration and velocity of the moving platform along the respective direction parallel to the x axis, y axis and z axis are varied. The conclusions are provided at the end of the paper. © 2012 Elsevier Ltd. All rights reserved.

By taking the Delta robot as the object of study, this paper deals with the methodology of the dimensional synthesis of the three translational degrees of freedom parallel robot while considering the kinematic anisotropic property. The velocity transmission index is employed as the objective function of the optimization design. The physical meaning of the velocity transmission index is the maximum of the input angular velocity when the moving platform translates with an assigned velocity. The determinant of the direct kinematic Jacobian matrix, the ratio of the machine volume to that of the desired workspace and the difference between the radius of the base and the radius of the moving platform are adopted as the constraints for the dimensional synthesis in order to make the Delta robot have a good transmission behavior between the distal links, keep far away from the direct kinematic singular configuration, not to be a very tall and slender configuration, achieve the desired performance without large dimension and big building cost. The example of the dimensional synthesis of the Delta robot is presented in the simulation while considering the maximum velocity requirements for the moving platform along the respective direction parallel to the x axis, y axis and z axis are varied.

A series of neutral cubic nickel(II)-imidazolate Ni8L 12X4 cages were prepared by rational choices of substituents and anions with solvothermal subcomponent self-assembly technology. Both substituents and halide anions play a critical role in the formation and stabilization of cubic cages. Changing one of the factors in the reaction will switch the final structure to a Ni14L24 rhombic dodecahedral cage. The cubic cage can transform to a large rhombic dodecahedral cage in the presence of methylamine at room temperature accompanied by a color change from purple to light yellow. © 2013 American Chemical Society.

A new luminescent entangled (srs nets with two-fold interpenetration, linked via short Cu⋯Cu distances of ca. 2.8 Å) MOF, namely, [(CuCN)3L·(guest)x]n (L = 2,6-bis((3,5-dimethyl-1H-pyrazol-4-yl)methyl)pyridine; x = 1 or 2), which contains microporous channels, is synthesized. This MOF material shows structural dynamics upon adsorption of various volatile organic solvent molecules, accompanied by reversible guest responsive colour changes of the fluorescence emission that are discernible by the naked eyes. The vacuated form of this material can also exhibit qualitative solvate-optical sensing behaviours toward various mixed solvents. Moreover, a quantitative real-time monitoring device is constructed that implements the determination of acetonitrile vapour pressure through optical response, which causes a drastic emission change from blue to yellow. The detailed structural elucidation provides structure-property understanding for the host-guest responsive dynamics. This journal is © The Royal Society of Chemistry 2013.
