The equivalence of bilinear forms
Journal of Algebra, 1973 Let B: I’ x V -+ F be a bilinear form on the finite dimensional vector space V over the field F. No assumptions such as symmetry or skew symmetry are made, although we assume that B is nondegenerate. Another such form C: W x W + F is equivalent to B if there is an isomorphism q~: V -+ W such that C(cpu, TV) = B(u, V) f or all u and z, in V, such a p is

Equivalent Forms of the Multivariate Portmanteau Statistic [PDF]
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1981 SUMMARY The Box-Pierce portmanteau test for univariate autoregressive moving-average (arma) time-series models has been generalized to multivariate time-series models by several authors, and several different definitions of the test statistic have resulted.

Versatile vector tools for efficient protein screening across multiple expression systems
FEBS Open Bio, EarlyView.A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

The undecidability of form equivalence for context-free and E0L forms
Theoretical Computer Science, 1984 AbstractThis paper studies the decidability status of various equivalence problems in form theory. Most of our discussions concern the notion of a language form. We compare the form equivalence problem between language forms with the ordinary equivalence problem between languages.

On the Equivalence of Algebraic Approaches to the Minimization of Forms on the Simplex [PDF]
, 2005 We consider the problem of minimizing a form on the standard simplex [equivalently, the problem of minimizing an even form on the unit sphere]. Converging hierarchies of approximations for this problem can be constructed, that are based, respectively, on results by Schmudgen-Putinar and by Polya about representations of positive polynomials in terms of

Calibrating and testing tissue equivalent proportional counters with 37Ar [PDF]
, 1994 A method for testing and calibrating tissue equivalent proportional counters with37Ar is described.37Ar is produced by exposure of argon in its normal isotope composition to thermal neutrons. It is shown that - up to volume ratios of 0.01 of argon to the

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA
FEBS Open Bio, EarlyView.PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.
