α-Connections and a Symmetric Cubic Form on a Riemannian Manifold

open access: yesEntropy, 2017
In this paper, we study the construction of α -conformally equivalent statistical manifolds for a given symmetric cubic form on a Riemannian manifold.

On equivalence of binary forms

open access: yesJournal of Number Theory, 1983
AbstractIn this paper the question of equivalence of two binary forms is related to certain properties of the roots. A method is given to determine whether or not two forms are equivalent. This method applies to a wide class of forms, though not all.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Equivalence and normal forms of bilinear forms

open access: yesLinear Algebra and its Applications, 2014
We present an alternative account of the problem of classifying and finding normal forms for arbitrary bilinear forms. Beginning from basic results developed by Riehm, our solution to this problem hinges on the classification of indecomposable forms and in how uniquely they fit together to produce all other forms. We emphasize the use of split forms, i.

AscF in the mycobacterial CIII–CIV supercomplex lacks metal and nucleotide binding but links malate oxidation to respiration

open access: yesFEBS Letters, EarlyView.
The mycobacterial CIII‐CIV respiratory supercomplex is an obligate assembly, encompassing several subunits of unknown functions. We have characterized the intracellular subunit AscF, and show that it is unlikely to be a sensor for metals or nucleotides, but is required for growth on nonfermentable energy sources, and likely works as an adapter for ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

open access: yesMolecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

An extended reverse Hardy–Hilbert’s inequality in the whole plane

open access: yesJournal of Inequalities and Applications, 2018
Using weight coefficients, a complex integral formula, and Hermite–Hadamard’s inequality, we give an extended reverse Hardy–Hilbert’s inequality in the whole plane with multiparameters and a best possible constant factor.

The equivalence of bilinear forms

open access: yesJournal 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]

open access: yesJournal 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.
