The paper concerns the well-posedness and long-term asymptotics of growth–fragmentation equation with unbounded fragmentation rates and McKendrick–von Foerster boundary conditions. We provide three different methods of ...
Angular equivalence of norms, introduced by Kikianty and Sinnamon (2017), is a notion of norm equivalence that is more attuned to the geometry of the norms. For certain geometrical properties and two angularly equivalent ...

This note generalizes several existing results related to Hermite–Hadamard inequality
using h-Godunova–Levin and (h1, h2)-convex functions using a fractional integral operator associated
with the Caputo–Fabrizio fractional ...

Highly accurate cryptocurrency price predictions are of paramount interest to investors
and researchers. However, owing to the nonlinearity of the cryptocurrency market, it is difficult
to assess the distinct nature of ...

Vasicek’s asymptotic single risk factor (ASRF) model is employed by the Basel Committee
on Banking Supervision (BCBS) in its internal ratings-based (IRB) approach for estimating credit losses
and regulatory credit risk ...

Asset Liability Management (ALM) is an essential risk management technique in Quantitative Finance and
Actuarial Science. It aims to maximise a risk-taker’s ability to fulfil future liabilities. ALM is especially critical
in ...

Vaccine boosters have been recommended to mitigate the spread of the coronavirus disease 2019 (COVID-19)
pandemic. A mathematical model with three vaccine doses and susceptibility is formulated. The model is
calibrated ...
CTCE-9908, a CXC chemokine receptor 4 (CXCR4) antagonist, prevents CXCR4 phosphorylation and inhibits the interaction with chemokine ligand 12 (CXCL12) and downstream signalling pathways associated with metastasis. This ...

Trees are partial orders in which every element has a linearly
ordered set of predecessors. Here we initiate the exploration of the
structural theory of trees with the study of different notions of branching
in trees ...
The term “high-risk population” refers to individuals with an increased likelihood of contracting a severe illness or disease due to factors such as age, underlying medical conditions, pregnancy, geographical location, or ...
Chemical reactions occur everywhere in both natural and artificial systems. Some of the reactions occur during the flow of a fluid (such a process is referred to as a reactive flow). Given the hazardous nature of some ...
On the basis of the WHO legitimated fear that there will be an avian influenza virus strain capable of mutating once it reaches the human population and sustains human-to-human transmissions, we formulate an hypothetical ...

In this this paper all binary codes of length 552 which admit the sporadic simple group Co3 as an imprimitive transitive permutation group are determined. Our aim is to understand the results also by using theoretical ...

In this note, we show that the main result (Theorem 3.2) due
to Asim et al. (Appl. Gen. Topol., 23(2), 363-376 (2022)
https://doi.org/10.4995/agt.2022.17418) is still valid if we remove the
assumption of continuity of ...

We explore the spatial spread of vector-borne infections with conditional vector preferences, meaning that vectors do not visit hosts at random. Vectors may be differentially attracted toward infected and uninfected hosts ...
