Remarks on Some Recent Fixed Point Results on Quaternion-Valued Metric Spaces by Ravi P. Agarwal, Hamed H. Alsulami, Erdal Karapınar, Farshid Khojasteh

“…Very recently, Ahmed et al. introduced the notion of quaternion-valued metric as a generalization of metric and proved a common fixed point theorem in the context of quaternion-valued metric space. …”

Thermodynamical Restrictions and Wave Propagation for a Class of Fractional Order Viscoelastic Rods by Teodor M. Atanacković, Sanja Konjik, Ljubica Oparnica, Dušan Zorica

“…We discuss thermodynamical restrictions for a linear constitutive equation containing fractional derivatives of stress and strain of different orders. Such an equation generalizes several known models. The restrictions on coefficients are derived by using entropy inequality for isothermal processes. …”

Metering effects in population systems by Erika T. Camacho, Christopher M. Kribs-Zaleta, Stephen Wirkus

“…While the level of the target population in theconstant-influx system generally remains between the local extrema of the samepopulation in the metered model, the same is not always true for other statevariables in the system. …”

Projective varieties have countably many real forms by Labinet, Timothée L.

“…In this note, we check that a complex projective algebraic variety has (at most) countably many real forms. We more generally prove it when the field of reals is replaced with a field that has only countably many finite extensions up to isomorphism. …”

Comparing Estimation Methods for the FPLD by Agostino Tarsitano

“…In particular, we present a five-parameter version of the generalized lambda distribution (FPLD). Three alternative methods for estimating its parameters are proposed and their properties are investigated and compared by making use of real and simulated datasets. …”

Lax Representation and Darboux Solutions of the Classical Painlevé Second Equation by Irfan Mahmood, Muhammad Waseem

“…The new linear system of that equation carries similar structure as other integrable systems possess in the AKNS scheme. Finally, we generalize the Darboux transformation of the classical Painlevé second equation to the N-th form in terms of Wranskian.…”

On New χ-Fixed Point Results for λ−Υ,χ-Contractions in Complete Metric Spaces with Applications by Babak Mohammadi, Wutiphol Sintunavarat, Vahid Parvaneh

“…The main aim of this work is to introduce the new concept of λ−Υ,χ-contraction self-mappings and prove the existence of χ-fixed points for such mappings in metric spaces. Our results generalize and improve some results in existing literature. …”

RAS in Pregnancy and Preeclampsia and Eclampsia by M. Rodriguez, J. Moreno, J. Hasbun

“…Preeclampsia is a common disease of pregnancy characterized by the presence of hypertension and commitment of many organs, including the brain, secondary to generalized endothelial dysfunction. Its etiology is not known precisely, but it involved several factors, highlighting the renin angiotensin system (RAS), which would have an important role in the origin of multisystem involvement. …”

On minimal hypersurfaces of nonnegatively Ricci curved manifolds by Yoe Itokawa

“…More precisely, a covering space of M is shown to split off a compact domain and ∑ is shown to be a smooth totally geodesic submanifold. This generalizes a theorem due to Kasue and Meyer.…”

Separable functors in corings by J. Gómez-Torrecillas

“…In particular, we prove that the induction functor stemming from every morphism of corings has a left adjoint, called ad-induction functor. This construction generalizes the known adjunctions for the categories of Doi-Hopf modules and entwined modules. …”
