Critical phenomena of nonequilibrium dynamical systems with two absorbing states

open access: yes, 1997
We study nonequilibrium dynamical models with two absorbing states: interacting monomer-dimer models, probabilistic cellular automata models, nonequilibrium kinetic Ising models.

Treeless vegetation of the Australian Alps [PDF]

open access: yes, 2013
Based on 1222 floristic quadrat samples, 56 plant communities were identified in treeless vegetation in the Australian Alps of south-eastern Australia. (c. 35º 30´–38ºS, 146°–149°E). The study encompassed vegetation from above the upper limit of trees on

Floristic variation in Sphagnum-dominated peatland communities of the Central Highlands, Victoria [PDF]

open access: yes, 2013
The floristic composition of Sphagnum-dominated peatlands in the Central Highlands region of Victoria was surveyed (37º 25´ S; 145º 50´ E). NMDS ordination and cluster analysis divided the peatland sites into two broad groups with altitude being the most

Propagation and Extinction in Branching Annihilating Random Walks

open access: yes, 1994
We investigate the temporal evolution and spatial propagation of branching annihilating random walks in one dimension. Depending on the branching and annihilation rates, a few-particle initial state can evolve to a propagating finite density wave, or ...

Pair Contact Process with Diffusion: Failure of Master Equation Field Theory

open access: yes, 2004
We demonstrate that the `microscopic' field theory representation, directly derived from the corresponding master equation, fails to adequately capture the continuous nonequilibrium phase transition of the Pair Contact Process with Diffusion (PCPD).

One Dimensional Nonequilibrium Kinetic Ising Models with Branching Annihilating Random Walk

open access: yes, 1994
Nonequilibrium kinetic Ising models evolving under the competing effect of spin flips at zero temperature and nearest neighbour spin exchanges at $T=\infty$ are investigated numerically from the point of view of a phase transition. Branching annihilating

Supervised and unsupervised learning of -dimensional even-offspring branching annihilating random walks

open access: yesMachine Learning: Science and Technology
Machine learning (ML) of phase transitions (PTs) has gradually become an effective approach that enables us to explore the nature of various PTs more promptly in equilibrium and nonequilibrium systems.

Theoretical investigation of bulk acoustic waves with high electromechanical coupling coefficient in c-axis-tilted wurtzite ScAlN

open access: yesAIP Advances
Scandium aluminum nitride (ScAlN) has gained significant attention as a piezoelectric material for bulk acoustic wave (BAW) resonators, offering a promising alternative to conventional aluminum nitride (AlN) due to its superior piezoelectric properties ...

Mixed Bruhat operators and Yang-Baxter equations for Weyl groups

open access: yes, 1998
We introduce and study a family of operators which act in the span of a Weyl group $W$ and provide a multi-parameter solution to the quantum Yang-Baxter equations of the corresponding type.
