Quadratic BH-algebras and Quadratic TM-algebras
In this paper we present the notion of “quadratic” BH-algebra and TM-algebra, and show that every quadratic BH-algebra and TM-algebra has a product of the form , where ; if is a field with and BCI-algebra.

Quadratic variation and quadratic roughness
We study the concept of quadratic variation of a continuous path along a sequence of partitions and its dependence with respect to the choice of the partition sequence. We define the concept of quadratic roughness of a path along a partition sequence and show that, for Hölder-continuous paths satisfying this roughness condition, the quadratic variation

Reformulating mixed-integer quadratically constrained quadratic programs [PDF]
It is well known that semidefinite programming (SDP) can be used to derive useful relaxations for a variety of optimisation problems. Moreover, in the particular case of mixed-integer quadratic programs, SDP has been used to reformulate problems, rather ...

Children's physiological reactivity in emotion contexts and prosocial behavior
Introduction Building on prior evidence that prosocial behavior is related to the regulation of personal distress in difficult situations, and given that physiological regulation is a central contributor to effective emotion regulation, this ...

Evolution Model for Epidemic Diseases Based on the Kaplan-Meier Curve Determination
We show a simple model of the dynamics of a viral process based, on the determination of the Kaplan-Meier curve P of the virus. Together with the function of the newly infected individuals I, this model allows us to predict the evolution of the resulting

Unramified Quadratic Extensions of a Quadratic Field
The authors determine all quartic number fields \(L/\mathbb{Q}\) possessing a quadratic subfield \(\mathbb{Q}\subset K\subset L\) such that \(L/K\) is unramified at all finite primes. They do this by an explicit calculation of the generators and make no use of Hilbert's theory.

The Composite Theorem of Ternary Quadratic Inequalities and its Applications [PDF]
In this paper, we establish the composite theorem of ternary quadratic inequalities by using the Decision Theorem and Hölder inequality. Its applications in triangle inequalities are discussed, and several problems and conjectures are put ...

Gap inequalities for non-convex mixed-integer quadratic programs [PDF]
Laurent and Poljak introduced a very general class of valid linear inequalities, called gap inequalities, for the max-cut problem. We show that an analogous class of inequalities can be defined for general non-convex mixed-integer quadratic programs ...

Minimax quadratic estimation of a quadratic functional
Let \(f\) be a real function and consider its noisy sample observations \(v_ i=f(t_ i)+z_ i\), \(i=1,2,...,n\), where \(t_ i=-\pi +2\pi (i/n)\) are equispaced on \([-\pi,\pi]\) and the noise terms \(z_ i\) are iid \(N(0,\sigma^ 2)\). Let \(f^{(k)}(t)\) be the \(k\)th derivative of \(f\). The authors consider the estimation of the quadratic functional \(
