Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

open access: yesBiological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

Hyers-Ulam Stability of a Bi-Jensen Functional Equation on a Punctured Domain

open access: yesJournal of Inequalities and Applications, 2010
We obtain the Hyers-Ulam stability of a bi-Jensen functional equation: and simultaneously . And we get its stability on the punctured domain.

On Jensen’s and the quadratic functional equations with involutions [PDF]

open access: yesProyecciones (Antofagasta), 2017
We determine the Solutions f : S → H of the generalized Jensen’s functional equation f( x + σ(y)) + f( x + τ(y)) = 2f(x), x , y∈ Sand the solutions f : S → H of the generalized quadratic functional equationf ( x + σ(y)) + f (x + τ(y)) = 2f (x) + 2f (y),    x, y ∈ S,where S is a commutative semigroup, H is an abelian group (2-torsion free in the first ...

The power of many: when genetics met yeasts and high‐throughput

open access: yesBiological Reviews, EarlyView.
ABSTRACT In recent years, complex technological capabilities have evolved, driven by the need to solve complex and integrative biological questions through global analyses. New equipment allows the scaling up and automation of processes which previously were carried out on a very limited scale.

Everywhere differentiability of viscosity solutions to a class of Aronsson's equations [PDF]

open access: yes, 2014
For any open set $\Omega\subset\mathbb R^n$ and $n\ge 2$, we establish everywhere differentiability of viscosity solutions to the Aronsson equation $$ =0 \quad \rm in\ \ \Omega, $$ where $H$ is given by $$H(x,\,p)==\sum_{i,\,j=1}^na^{ij}(x)p_i p_j,\ x\in\

Reaction-diffusion processes and non-perturbative renormalisation group

open access: yes, 2005
This paper is devoted to investigating non-equilibrium phase transitions to an absorbing state, which are generically encountered in reaction-diffusion processes. It is a review, based on [Phys. Rev. Lett. 92, 195703; Phys. Rev. Lett.

Stability of an alternative Jensen's functional equation [PDF]

open access: yesScienceAsia, 2013
We prove the Hyers-Ulam stability of an alternative Jensen's functional equation(f(x)+f(y))=2 = f((x+ y)=2) in the class of mappings from 2-divisible abelian groups to Banach spaces.

More Than 10 Years on: Does a State‐of‐the‐Art Review and Synthesis Offer New Frameworks to Guide Future Design for Remanufacturing Research?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT There is strong evidence that design for remanufacturing (DfRem) can reduce initial‐design carbon emissions by up to 30%, and that product design can critically affect remanufacturing feasibility, yet academic adoption of DfRem remains limited.

Higher Ring Derivation and Intuitionistic Fuzzy Stability

open access: yesAbstract and Applied Analysis, 2012
We take account of the stability of higher ring derivation in intuitionistic fuzzy Banach algebra associated to the Jensen type functional equation. In addition, we deal with the superstability of higher ring derivation in intuitionistic fuzzy Banach ...

Hyers–Ulam stability and hyperstability of a Jensen-type functional equation on 2-Banach spaces

open access: yesJournal of Inequalities and Applications, 2022
The main aim of this paper is to establish the Hyers–Ulam stability and hyperstability of a Jensen-type quadratic mapping in 2-Banach spaces. That is, we prove the various types of Hyers–Ulam stability and hyperstability of the Jensen-type quadratic ...
