The natural explanation of the excitation spectrum of the spin1 antiferromagnetic Heisenberg chain is given from the viewpoint of the spin-1/2 ferromagnetic-antiferromagnetic alternating Heisenberg chain. The energy spectrum of the latter is calculated with fixed momentum k by numerical diagonalization of finite size systems. It consists of a branch of propagating triplet pair (triplet wave) an...

In this paper, we can decide the operation order with unknown potential order requirements. The scheduling architecture is proposed in this paper, First, the branch-andbound search based on Markov chain method is proposed. The Markov chain gets the service rate records and arrival rate records from the MES(manufacturing execution system). We can get the possible beginning times of operations fo...

Maple syrup urine disease is a rare autosomal recessive inborn error of metabolism of branch chain amino acids the condition is named because of distinctive sweet odour of affected infants urine. MSUD is caused by deficiency of branch chain alpha keto acid dehydrogenase enzyme complex, leading to accumulation of the branch chain amino acids (leucine, isoleucine, valine) and their toxic by produ...

In this paper it is argued that the central charge extension of the Coulomb branch of N = 4 SYM theory appears as a limit of Beisert’s central charge extension of the planar N = 4 spin chain in the presence of boundaries. These boundaries are interpreted as D-branes that source the central charge and are realized as giant gravitons and dual giant gravitons in the AdS dual. The BPS states that c...

Traditional distribution network fault location methods often cannot be effectively applied for the structure of the branch in complex distribution network. A new accurate fault location for the single-phaseground fault in complex distribution network with structure of the branch based on Hilbert-Huang transform was proposed in this paper. First, the distribution network was modeled. The faults...

According to the length distribution of human introns, there is a large population of short introns with a threshold of 65 nucleotides (nt) and a peak at 85 nt. Using human genome and transcriptome databases, we investigated the introns shorter than 66 nt, termed ultra-short introns, the identities of which are scarcely known. Here, we provide for the first time a list of bona fide human ultra-...

Pyramidal cells, the most abundant neurons in neocortex, exhibit significant structural variability across different brain areas and layers in different species. Moreover, in response to a somatic step current, these cells display a range of firing behaviors, the most common being (1) repetitive action potentials (Regular Spiking-RS), and (2) an initial cluster of 2-5 action potentials with sho...

Continuous observation was performed using confocal laser scanning microscopy to visualize the three-dimensional microscopic growth of the brown-rot fungus, Postia placenta, for seventeen days. The morphological characterization of Postia placenta was quantitatively determined, including the tip extension rate, branch angle and branching length, (hyphal length between two adjacent branch sites)...
