The Development of a Community‐Led Child Protection Approach in Low‐ and Middle‐Income Countries

open access: yesChild Abuse Review, Volume 34, Issue 6, November/December 2025.
ABSTRACT Child protection actors, including community members, work to prevent and respond to violence, abuse, neglect and the exploitation of children. Child protection approaches implemented by nongovernmental organisations (NGOs) and other agencies are often located in communities but are not led by those communities.

On Generalized Avicenna Numbers

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 14, Page 13300-13316, 30 September 2025.
ABSTRACT Avicenna numbers that we define in this paper, are a class of figurate numbers, including icosahedral, octahedral, tetrahedral, dodecahedral, rhombicosidodecahedral numbers and cubes, play a key role in mathematics, physics and various scientific fields.

Coincidences in generalized Lucas sequences [PDF]

open access: yes, 2014
For an integer $k\geq 2$, let $(L_{n}^{(k)})_{n}$ be the $k-$generalized Lucas sequence which starts with $0,\ldots,0,2,1$ ($k$ terms) and each term afterwards is the sum of the $k$ preceding terms.

Christian Bohr. Discoverer of Homotropic and Heterotopic Allostery

open access: yesActa Physiologica, Volume 241, Issue S734, July 2025.
ABSTRACT This essay recounts and revisits the scientific contributions of Christian Bohr, highlighting his pivotal role in discovering allostery about 120 years ago. Bohr's meticulous experimentation led to identifying two distinct forms of allostery: homotropic (single‐ligand) and heterotropic (multi‐ligand), the latter widely recognized as the Bohr ...

Construction of generalized bicomplex Leonardo numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
In this paper, we introduce a new class of bicomplex numbers whose components are expressed in terms of bicomplex Leonardo numbers. The motivation for this study arises from the growing interest in generalizations of well-known integer sequences within ...

On Convolved Generalized Fibonacci and Lucas Polynomials [PDF]

open access: yes, 2013
We define the convolved h(x)-Fibonacci polynomials as an extension of the classical convolved Fibonacci numbers. Then we give some combinatorial formulas involving the h(x)-Fibonacci and h(x)-Lucas polynomials.

Pell Leonardo numbers and their matrix representations

open access: yesJournal of New Results in Science
In this study, we investigate Pell numbers and Leonardo numbers and describe a new third-order number sequence entitled Pell Leonardo numbers. We then construct some identities, including the Binet formula, generating function, exponential generating ...
