Understanding the behaviors of ecological systems is challenging given their multifaceted complexity. To proceed, theoretical models such as Lotka-Volterra dynamics with random interactions have been investigated by dynamical mean-field theory to provide insights into underlying principles how biodiversity and stability depend on randomness in interaction strength. Yet fully connected structures assumed these previous studies are not realistic, revealed a vast amount empirical data. We...

New low-temperature curable organic/inorganic hybrid polymers were designed and synthesized as gate dielectrics for organic thin-film transistors (OTFTs). Allyl alcohols introduced to polyhedral oligomeric silsesquioxane (POSS) via hydrosilyation produce an alcohol-functionalized POSS derivative (POSS-OH). POSS-OH was then reacted with hexamethoxymethylmelamine at carrying molar ratios 80 °C in the presence of a catalytic amount p-toluenesulfonic acid give highly cross-linked network...

Periodic environmental changes are commonly observed in nature from the amount of daylight to seasonal temperature. These usually affect individuals' death or birth rates, dragging system its previous stable states. When fluctuation abundance is amplified due such changes, extinction species may be accelerated. To see this effect, we examine how and mean time respond periodic changes. We consider a population wherein two coexist together implemented by three rules---birth, spontaneous death,...

We investigate the critical behavior of modified Kuramoto model with an asymmetric dynamic interaction which has been proposed to explain difference between synchronized frequency and average intrinsic frequency. find that discontinuous phase transition arises when oscillators interact only other whose phases are ahead. From comparison conventional in possesses reflection symmetry, we conclude dynamical symmetry breaking change structure play important roles changing nature from continuous ones.

Since conventional MLSE equalizers provide hard outputs, their use precludes soft decision channel decoding. This paper proposes a new output equalization technique based on the modified-MAP algorithm for GMSK mobile radio. A comparison of performance proposed with those other suboptimum algorithms (SOVA, SSA) is made. Simulation results over multipath fading channels are presented.
