Bone morphogenetic proteins (BMPs) regulate dorsal/ventral (D/V) patterning across the animal kingdom; however, the biochemical properties of certain pathway components can vary according to species-specific developmental requirements. For example, Tolloid (Tld)-like metalloproteases cleave vertebrate BMP-binding proteins called Chordins constitutively, while the Drosophila Chordin ortholog, Sh...

In this paper we establish the existence of positive solutions to a system of steady-state Neumann boundary problems. This system has been observed in some biological experiments, morphogen gradients; effects of Decapentaplegic (Dpp) and short gastrulation (Sog). Mathematical difficulties arise from this system being nonquasimonotone and semilinear. We overcome such difficulties by using the fi...

Some applications in microelectronics call for freestanding polyimide films with fine metallic wiring patterns that are thinner than commercially available copper-clad polyimide sheets, which are typically greater than 25 pm in thickness. This work describes a laserassisted technique to fabricate freestanding multilayer thin-film wiring with polyimide dielectric insulating layers that are less ...

Young modulus and toughness (KIC) of bulk solar grade silicon (SoG-Si) obtained by directional solidification metallurgical were determined. The was measured the technique impulse excitation vibration KIC determined using indentation method. Measurement values agree well with those available in literature. method proved to be a reliable, relatively simple, inexpensive, fast experimental measure...

The suboesophageal ganglion (SOG), which connects to both central and peripheral nerves, is the primary taste-processing center in the Drosophila’s brain. The neural oscillation in this center may be of great research value yet it is rarely reported. This work aims to determine the amount of unique information contained within oscillations of the SOG and describe the variability of these patter...

We report on the development of photosensitizer-conjugated gold nanorods (MMP2P-GNR) in which photosensitizers were conjugated onto the surface of gold nanorods (GNR) via a protease-cleavable peptide linker. We hypothesized that fluorescence and phototoxicity of the conjugated photosensitizers would be suppressed in their native state, becoming activated only after cleavage by the target protea...

Social media can have enormous benefits for organisations, but a failure to manage how these applications are used can have significant and unintended consequences. In this paper, the authors propose a conceptual Stages of Growth (SOG) Model for managing an organisation’s Social Media Business Profile (SMBP). Following extensive reviews of SOG models in the literature, social media practitioner...

The transfer of chemical vapour deposited graphene from its parent growth catalyst has become a bottleneck for many of its emerging applications. The sacrificial polymer layers that are typically deposited onto graphene for mechanical support during transfer are challenging to remove completely and hence leave graphene and subsequent device interfaces contaminated. Here, we report on the use of...
