Searching closed form analytic solutions to some nonlinear fractional wave equations
Numerous tangible incidents in physics, chemistry, applied mathematics and engineering are described successfully by means of models making use of the theory of derivatives of fractional order and research in this area has grown significantly.

Kaehler Submanifolds of Complex Space Forms
Under the notion ``diastasis'' introduced by \textit{E. Calabi} [Ann. Math., II. Ser. 58, 1-23 (1953; Zbl 0051.131)] the author proves the following theorem: Any two complex space forms of different types have no Kaehler submanifold in common, that is, (1) a Kaehler submanifold of \({\mathbb{C}}^ N\) cannot be a Kaehler submanifold of any complex ...

Characterization of Holomorphic Bisectional Curvature of GCR-Lightlike Submanifolds
We obtain the expressions for sectional curvature, holomorphic sectional curvature, and holomorphic bisectional curvature of a GCR-lightlike submanifold of an indefinite Kaehler manifold.

On generalized complex space forms satisfying certain curvature conditions
We study Ricci soliton $(g,V,\lambda)$ of generalized complex space forms when the Riemannian, Bochner and $W_{2}$ curvature tensors satisfy certain curvature conditions like semi-symmetric, Einstein semi-symmetric, Ricci pseudo symmetric and Ricci ...

Some characterizations of Pseudo-Complex space forms
In Duke Math. J. 40, 797-799 (1973; Zbl 0274.53021) the reviewer and \textit{K. Ogiue} proved that a Kähler manifold is a complex space-form if and only if it has constant anti-holomorphic sectional curvature. In this article, the authors extend this result to a pseudo-Kähler manifold.

Organoids in pediatric cancer research
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
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.

Almost Complex Surfaces in the Nearly Kähler SL(2,ℝ) × SL(2,ℝ)
The space S L ( 2 , R ) × S L ( 2 , R ) admits a natural homogeneous pseudo-Riemannian nearly Kähler structure. We investigate almost complex surfaces in this space.

Beta diversity of plant-pollinator networks and the spatial turnover of pairwise interactions. [PDF]
Interactions between species form complex networks that vary across space and time. Even without spatial or temporal constraints mutualistic pairwise interactions may vary, or rewire, across space but this variability is not well understood.

Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
