An unusual thermoelectric response was observed in n-type perovskite oxide La1-xCexCoO3. Combining transport and magnetic measurements, we found that the thermoelectric response is driven by the spin-state transition of Co3+. This transition destroys the spin blockade effect and induces an abrupt decrease of resistivity as well as an insulator-metal transition. In contrast to the resistivity ch...

(a) Consider a sequence of independent coin tosses with P[heads] = p and let Yn be the number of heads up to time n with Y0 = 0. Give the state space S and transition matrix for the process (Yn : n ∈ N0). Compute P[Yn = k] for all n, k ≥ 0 using the binomial formula. (b) Let (Zn : n ∈ N0) be a simple random walk on S = Z with transition matrix p(x, y) = pδy,x+1 + qδy,x−1. Use that Zn = 2Yn − n ...

Let (X,P ) be an irreducible, random walk on the state space X which is at most countable. We suppose that the (usually infinite) stochastic matrix P describes a Markov chain {Zn}n∈N defined on a probability space (Ω,F ,P) with transition probabilities p(x, y) := P[Zn+1 = y|Zn = x] homogeneous in time. Besides we consider the n-step transition probabilities {p(x, y)}x,y∈X which represent the st...

An MCHF atomic-structure package is presented based on dynamic memory allocation, sparse matrix methods, and a recently developed angular library. It is meant for large-scale calculations in a basis of orthogonal orbitals for groups of LS terms of arbitrary parity. For Breit-Pauli calculations, all operators – spin-orbit, spin-other orbit, spin-spin, and orbit-orbit – may be included. For trans...

Driving cycle (DC) plays an important role in designing and evaluating EVs, many Markov chain-based DC construction methods describe driving profiles of unfixed-line vehicles with state transition probability. However, for fixed-line electric vehicles, the time-sequence microtrips brings huge influences on their brake, drive, battery management systems. Simply describing topography, traffic, lo...

R. Alarcon Nuclear Physics Laboratory and Department ofPhysics, University ofIllinois, Champaign, Illinois 61820 (Received 8 October 1987) Proton and neutron transition densities in ' Si are examined by a combination of intermediate energy (e,e') and (p,p') reactions and mirror electromagnetic transition rates. This analysis is performed for the 2+i and 22 states at 2.234 and 3.499 MeV in Si. E...

In this paper we present a concept for using presence absence data to recover information on the population dynamics of predator prey systems. We use a highly complex and spatially explicit simulation model of a predator prey mite system to generate simple presence absence data: the number of patches with both prey and predators, with prey only, with predators only, and with neither species, al...

The available virial coefficients for the two-dimensional hard-disks model are transformed into a matrix representation of the thermodynamic potentials, which allows for an accurate description of the whole fluid phase, up to the phase transition. We find that the fluid phase terminates at the transition point, implying a second-order phase transition in accordance with the Kosterlitz-Thouless-...
