The ascidian neural plate has a grid-like organisation, with six rows and eight columns of aligned cells, generated by a series of stereotypical cell divisions. We have defined unique molecular signatures for each of the eight cells in the posterior-most two rows of the neural plate - rows I and II. Using a combination of morpholino gene knockdown, dominant-negative forms and pharmacological in...

The recent application of graph theory to brain networks promises to shed light on complex diseases such as Parkinson's disease (PD). This study aimed to investigate functional changes in sensorimotor and cognitive networks in Parkinsonian patients, with a focus on inter- and intra-connectivity organization in the disease-associated nodal and hub regions using the graph theoretical analyses. Re...

Numerical integration errors and volumetric locking in the near-incompressible limit are two outstanding issues in Galerkin-based meshfree computations. In this paper, we present a modified Gaussian integration scheme on background cells for meshfree methods that alleviates errors in numerical integration and ensures patch test satisfaction to machine precision. Secondly, a lockingfree small-st...

the influence of explant nodal positions on the in vitro shoot growth and proliferation were studied in the two rose cvs. ‘bianca’ and ‘el torro’. third, fourth and fifth nodal explants were cultured on the modified ms medium supplemented with 1.0 and 5.0 mg/l ba. in both the cultivars, higher rate of proliferation (‘bianca’ 3.75; ‘el torro’ 2.65) were obtained from the explants distal to the a...

This paper proposes an algorithm for transmission cost allocation (TCA) in a large power system based on nodal pricing approach using the multi-area scheme. The nodal pricing approach is introduced to allocate the transmission costs by the control of nodal prices in a single area network. As the number of equations is dependent on the number of buses and generators, this method will be very ti...

In this study, a scheme using the Finite Element Method (FEM) for calculating inverse dynamics is proposed and applied to openand closed-loop link mechanisms. In this scheme, the entire system is subdivided into discrete elements and evaluated as a continuum. A single-link structure of a pin joint and a rigid bar is expressed by using the Shifted Integration (SI) technique. The proposed scheme ...

This paper presents a new compact approximation method for the discretisation of second-order elliptic equations in one and two dimensions. The problem domain, which can be rectangular or non-rectangular, is represented by a Cartesian grid. On stencils, which are three nodal points for one-dimensional problems and nine nodal points for twodimensional problems, the approximations for the field v...

The low-lying states of light nuclei He and Be are studied in this letter. With the inherent nodal surface(INS) analysis approach, the quantum numbers and the spatial symmetries of the low-lying states with positive parity and negative parity of the two nuclei are deduced. The obtained energy spectrum structure agrees with experimental data well.
