We present evidence for methyl (as methyl or methoxy) transfer from the methyl-accepting chemotaxis proteins H1 and possibly H3 of Bacillus subtilis to the methyl-accepting chemotaxis protein H2. This methyl transfer, which has been observed in vitro (D. J. Goldman and G. W. Ordal, Biochemistry 23:2600-2606, 1984), was strongly stimulated by the chemoattractant aspartate and thus may play an im...

Reduced RNA and/or protein levels corresponding to the murine nm23-1 and human nm23-H1 complementary DNA clones have been correlated with high tumor metastatic potential in several rodent model systems and human breast carcinomas. We report the identification of a second human nm23 gene, designated nm23-H2. The pNM23-H2S complementary DNA clone predicted a Mr 17,000 protein 88% identical to nm2...

Let H1 be an n × n invertible Hermitian matrix, and let U(H1) be the group of n × n H1-unitary matrices, i.e., matrices A satisfying A H1A = H1. Suppose H2 is an m × m invertible Hermitian matrix. We show that a linear transformation φ : Mn → Mm satisfies φ(U(H1)) ⊆ U(H2) if and only if there exist invertible matrices S ∈ Mm, U, V ∈ U(H2) such that SH2S = [(Ia ⊕−Ib)⊗H1]⊕ [(Ic ⊕−Id)⊗ (H−1 1 )], ...

This study examines tone and phonation in White Hmong, a language with seven tones (traditionally described as: high, mid, low, high-falling, mid-rising, low-falling, and mid-low) and three phonations (low-falling tone is creaky, mid-low tone is breathy and the remaining tones are modal). Thirty-two speakers were recorded producing words with all seven tones; audio and electroglottographic reco...

Let H1∪P H2 be a Heegaard splitting of a closed 3-manifoldM , i.e., Hi (i = 1, 2) is a handlebody in M such that H1 ∪H2 = M , H1 ∩H2 = ∂H1 = ∂H2 = P . In [13], M.Scharlemann, and A.Thompson had introduced a process for spreading H1 ∪P H2 into a “thinner” presentation. The idea was polished to show that if the original Heegaard splitting is irreducible, then we can spread it into a series (A1 ∪P...

We present a new expression of the polynomial Hamiltonian of the Garnier system in two variables. 1. Main results The Garnier system in two variables is equivalent to the rational Hamiltonian system given by (see [18], cf. [3]) dq1 = ∂H1 ∂p1 dt + ∂H2 ∂p1 ds, dp1 = − ∂H1 ∂q1 dt− ∂H2 ∂q1 ds, dq2 = ∂H1 ∂p2 dt + ∂H2 ∂p2 ds, dp2 = − ∂H1 ∂q2 dt− ∂H2 ∂q2 ds, H1 = − q1(q1 − 1)(q1 − t)(q1 − s)(q2 − t) (...

Abstract All extant purely probabilistic measures of explanatory power satisfy the following technical condition: if Pr(E | H1) > H2) and ∼H1) < ∼H2), then H1’s with respect to E is greater than H2’s E. We argue that any measure satisfying this condition faces three serious problems—the Problem Temporal Shallowness, Negative Causal Interactions, Nonexplanations. further many such face a f...

The extension of classical analysis to time series data is the basic problem faced in many fields, such as engineering, economic and medicine. The main objective of discriminant time series analysis is to examine how far it is possible to distinguish between various groups. There are two situations to be considered in the linear time series models. Firstly when the main discriminatory informati...

The tau (MAPT) locus exists as two distinct clades, H1 and H2. The H1 clade has a normal linkage disequilibrium structure and is the only haplotype found in all populations except those derived from Caucasians. The H2 haplotype is the minor haplotype in Caucasian populations and is not found in other populations. It shows no recombination over a region of 2 Mb with the more common H1 haplotype....
