Why are these synapses special? Because the electrical signals they transmit are not the same as those in other parts of the brain. Conventional synapses convey information arriving as a ‘pulse code’; action potentials lasting a few milliseconds trigger a transient burst of vesicle fusion and the amplitude of the action potential is fixed. But ribbon synapses transmit ‘analogue signals’, such a...

We present ‘Ribbon Proofs’, a graphical proof system for the Logic of Bunched Implications (BI). We give the informal, graphical, notation, we formalise the system algebraically and sketch the proof of its soundness and completeness. We discuss the spatial and geometrical nature of the proof system and its relation to BI’s spatial model theory.

background: echinococcus granulosus cultivation is very important for improvement of different aspect of medical and veterinary researches. despite many advances in this case, there is a missing link for in vitro life cycle of adult worms and it is fertili-zation. regarding the researchers’ observations, self-fertilization can be done in worms living in dog intestine, but despite all sorts of e...

When different ratios of Eucalyptus leaves and cow dung were mixed and analyzed for worm multiplication, amongst the three ratios (1:1, 3:1 and 3:2), 3:1 was the most suitable ratio as far as multiplication of worms is concerned. There was no multiplication of worms up to two weeks but the worms started multiplying at a significant rate after two weeks. After eight weeks of inoculation the numb...

Hall-Littlewood functions indexed by rectangular partitions, specialized at primitive roots of unity, can be expressed as plethysms. We propose a combinatorial proof of this formula using Schilling’s bijection between ribbon tableaux and ribbon rigged configurations.

This study reports the preparation of soft magnetic ribbons of Fe-based amorphous alloys using the single-roller melt-spinning technique. Ribbon width varied from 142 mm to 213 mm and, with a thickness of approximately 22 μm 2 μm. The microstructure and magnetic properties of the ribbons were characterized by differential scanning calorimeter (DSC), X-ray diffraction (XRD), vibrating sample mag...
