Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Molecular Oncology, EarlyView.Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

On the derivations, generalized derivations and ternary derivations of degree $n$
Rendiconti del Circolo Matematico di Palermo Series 2, 2022In this paper, we introduce the concepts of derivation of degree $n$, generalized derivation of degree $n$ and ternary derivation of degree $n$, where $n$ is a positive integer, and then we study algebraic properties of these mappings. For instance, we study the image of derivations of degree $n$ on algebras and in this regard we prove ...

Deriving derivatives of derivative securities
The Journal of Computational Finance, 2000We use various techniques to simplify the derivations of "greeks" of path-independent claims in the Black-Merton-Scholes model. We first interpret delta, gamma, speed, and other higher order spatial derivatives of these claims as the values of certain quantoed contingent claims.

NORMAL DERIVATIONS AND SEQUENT DERIVATIONS
Journal of Philosophical Logic, 2008Normal proofs in natural deduction systems for intuitionistic logic roughly correspond to cut-free sequent derivations. This article elaborates on this correspondence. First, a system \(\mathcal{N}\) for natural deductions and a system \(\mathcal{S}\) for sequent derivations are introduced.

1. The notion of derivability. Italic capitals, with or without subscripts, will be used as variables. They are to take as values some manner of elements which may for the present be left undetermined. Now let us consider abstractly the notion of the derivability of an element X from one or more specified elements by a series of steps of a specified ...

Derived Varieties and Derived Equational Theories
International Journal of Algebra and Computation, 1998This paper describes a derivation process for varieties and equational theories using the theory of hypersubstitutions and M-hyperidentities. A hypersubstitution σ of type τ is a map which takes each n-ary operation symbol of the type to an n-ary term of this type.

Derived Equivalences As Derived Functors
Journal of the London Mathematical Society, 1991In [J. Lond. Math. Soc., II. Ser. 39, No.3, 436-456 (1989; Zbl 0642.16034)], we proved that two algebras \(\Lambda\) and \(\Gamma\) are ``derived equivalent'', meaning that the derived category of modules for \(\Lambda\) is equivalent to that for \(\Gamma\), precisely when \(\Gamma\) is isomorphic to the endomorphism ring of what we called a ``tilting ...

The customary language-theoretic derivative of a word u with respect to a word v means the deletion of v from the beginning or end of u. We investigate the natural generalization, where v can be deleted from an arbitrary position in u. Apart from general closure and decidability properties, we pay special attention to regular languages, obtaining an ...

Man betrachtet die Ableitbarkeit im klassischen Prädikatenkalkül durch irgendein \(\langle R,X\rangle\), wobei \(X\) eine Menge von Formeln ist, die als Axiome betrachtet werden, und \(R\) eine Menge von Ableitungsregeln ist. Bei fixierten \(\langle R,X\rangle\) soll für eine beliebige Regelmenge \(r\) der Ausdruck \(r\in\text{Der}(R,X)\) bedeuten ...

The diagonal formula in the theory of nonatomic games expresses the idea that the Shapley value of each infinitesimal player is his marginal contribution to the worth of a “perfect sample” of the population of all players, when averaged over all possible sample sizes.
