Cellular-P spaces for some Lindelöf-type properties
Applied General TopologyIn this paper, we study two classes of topological spaces: cellular-almost Lindelöf spaces and cellular-weakly Lindelöf spaces. We prove that the classes of cellular-Lindelöf, cellular weakly Lindelöf and cellular-almost Lindelöf are distinct.

The dimension of product spaces [PDF]
Proceedings of the National Academy of Sciences, 1978 The covering dimension of a product space can exceed the sum of the dimensions of its factors. A separable metric space X and a paracompact space Y are constructed such that dim X + dim Y = 0 < 1 = dim( X ×

Rotational Hypersurfaces in S3(r)R Product Space
Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2017 We consider rotational hypersurfaces in S3(r) R product space of five dimensional Euclidean space E5. We calculate the mean curvature and the Gaussian curvature, and give some results.

On Contraction Principles in Product Spaces and Applications in Iterated Function Systems
AxiomsThis paper develops an extension of the research work by Proinov to the product spaces X|I| (I is representing an indexing set). This paper also introduces a novel class of (L;Y)-contractions defined on a supremum metric (X|I|,d′).

Signal Processing On Product Spaces
ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2023 We establish a framework for signal processing on product spaces of simplicial and cellular complexes. For simplicity, we focus on the product of two complexes representing time and space, although our results generalize naturally to products of simplicial complexes of arbitrary dimension.

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Topology and its Applications, 2005 It is well known that every product of a locally compact space with a \(k\)-space is a \(k\)-space. In the paper under review, characterizations of a \(k\)-space \(X\) are discussed such that \(X\times Y\) is a \(k\)-space for every space \(Y\) in some class of \(k\)-spaces.

On productively Lindelöf spaces
Topology and its Applications, 2011 The class of spaces such that their product with every Lindelöf space is Lindelöf is not well-understood. We prove a number of new results concerning such productively Lindelöf spaces with some extra property, mainly assuming the Continuum Hypothesis.
