A study of the time evolution and a stability analysis of the phases in the extremely diluted Blume-Emery-Griffiths neural network model are shown to yield new phase diagrams in which fluctuation retrieval may drive pattern retrieval. It is shown that saddle-point solutions associated with fluctuation overlaps slow down the flow of the network states towards the retrieval fixed points. A compar...

The Blume-Emery-Griffiths spin glass is studied by renormalization-group theory in d=3 . The boundary between the ferromagnetic and paramagnetic phases has first-order and two types of second-order segments. This topology includes an inverted tricritical point, first-order transitions replacing second-order transitions as temperature is lowered. The phase diagrams show disconnected spin-glass r...

Sinopla humeralis Signoret, 1864 is revalidated and removed from the synonymy of Sniploa obsoletus Signoret, 1864. The first formal records from it original description and first data about its biology are provided. The type species of the genus Sinopla is discussed and the concept of the genus is expanded. The association of Sinopla humeralis with the southern beech Nothofagus Blume and it dis...

We report large systematic errors in Monte Carlo simulations of the tri-critical Blume-Capel model using single spin Metropolis updating. The error, manifest as a 20% asymmetry in the magnetisation distribution, is traced to the interplay between strong triplet correlations in the shift register random number generator and the large tricritical clusters. The effect of these correlations is visi...

A new species, Popowia bachmaensis Ngoc, Tagane & Yahara, sp. nov. is described from Bach Ma National Park in Thua Thien Hue Province, Central Vietnam. This species is morphologically similar to Popowia pisocarpa (Blume) Endl. ex Walp., but can be readily distinguished from it by its lower stems, smaller leaves, shorter flowering pedicels, shorter carpels, longer sepals and inner petals. A deta...

The first order phase transition of the three-dimensional Blume Capel are investigated using cooling algorithm which improved from Creutz Cellular Automaton for the D/J = 2.9 parameter value in the first order phase transition region. The analysis of the data using the finite-size effect and the histogram technique indicate that the magnetic susceptibility maxima and the specific heat maxima in...

Rancangan Acak Lengkap (RAL) digunakan dalam dengan 8 perlakuan : Z1 = tanpa ZPT, Z2= + Auksin 1,5 ml/L, Z3= +Thidiazuron 1 ppm, Z4= +Auksin ml/L Th...

Good germination of rattan jernang (Daemonorops draco Blume) seeds will increase power, rate, and value. However, there are still obstacles to germination, because the have a dormancy period. Soaking in Atonic Growth Regulatory Substances (ZPT) is one method that can be used break thedormancy period seeds. This study aims determine dose soaking time on value (D. Blume). The four treatments 3 gr...

We derive probabilistic limit theorems that reveal the intricate structure of the phase transitions in a mean-field version of the Blume-Emery-Griffiths model [4]. These probabilistic limit theorems consist of scaling limits for the total spin and moderate deviation principles (MDPs) for the total spin. The model under study is defined by a probability distribution that depends on the parameter...
