We introduce the notion of a matron M = {Mn,m} whose submodules M∗,1 and M1,∗ are non-Σ operads. We construct a functor from PROP to matrons and its inverse, the universal enveloping functor. We define the free matron H∞, generated by a singleton in each bidegree (m, n) 6= (1, 1), and define an A∞-bialgebra as an algebra over H∞. We realize H∞ as the cellular chains of polytopes {KKn,m = KKm,n}...

Sum of Pseudoproducts (SPPs) are three-level network structures that give a good compromise between compact representation and small depth of the resulting circuit. In this paper the testability of circuits derived from SPPs is studied. For SPPs several restricted forms can be considered. While full testability can be proved for some classes, others are shown to contain redundancies. Experiment...

Directional switching in a self-propelled particle model with delayed interactions is investigated. It is shown that the average switching time is an increasing function of time delay. The presented results are applied to studying collective animal behavior. It is argued that self-propelled particle models with time delays can explain the state-dependent diffusion coefficient measured in experi...

This paper has studied the trends in the total factor productivity (TFP) growth of rice in India for the period 1980-81 to 2009-10 and has decomposed the TFP growth into its constituent components, viz. change in technical progress and technical efficiency. The study has used Malmquist Productivity Index approach through data envelopment analysis to estimate the TFP. The analysis has also been ...

Calocybe indica, known as milky white mushroom, grows and cultivated in the sub-tropical and temperate zones of South Asia. We investigated the most suitable supplements and their levels for the commercial cultivation of milky white mushroom. Rice bran, maize powder, and wheat bran with their different levels (10, 20, 30, 40, and 50%) were used as supplements to evaluate the yield and yield con...

Rice Bran wax is obtained from natural sources and is abundantly available in the country. Rice bran wax is suitable for use in chocolate enrobes, as an enteric coating for candy and lozenges, as a plasticizing material in chewing gums etc. Present study attempts to find if rice bran wax is useful as ointment base. The oleaginous type ointment base is prepared by using rice bran wax and evaluat...
