Dwarf Galaxies, MOND, and Relativistic Gravitation
Published 2010-01-01“…Relativistic theories containing MOND in the non-relativistic limit have now been formulated; they all contain new dynamical fields, which may serve as additional sources of gravitation that could reconcile cluster observations with MOND. Certain limits of these theories can also give the accelerating expansion of the Universe. …”

Non-parametric reconstruction of the fine structure constant with galaxy clusters
Published 2024-10-01“…This paper investigates potential cosmological variations in the fine structure constant ( $$\alpha $$ α ) through a non-parametric approach, using galaxy cluster observations as the primary cosmological probe. We employ two methodologies based on galaxy cluster gas mass fraction measurements derived from X-ray and Sunyaev–Zeldovich observations, along with luminosity distances from type Ia supernovae. …”

Superparamagnetic Clustering of Diabetes Patients Raman Spectra
Published 2019-01-01“…In this paper, we present a different way to the standard methods to classify Raman spectra whose grouping process is based on a phenomenon of clustering observed in nature at the atomic level and correctly described by the statistical physics model known as the Potts model, which represents the interacting spins on a crystalline lattice. …”

Interconnected cavernous structure of bacterial fruiting bodies.
Published 2012-01-01“…The mechanism consists of self-propelled cells aligning with each other and signaling by end-to-end contact to coordinate the process of differentiation resulting in a pattern of clusters observed in the experiment. The integration of novel OCT experimental techniques with computational simulations can provide new insight into the mechanisms that can give rise to the pattern formation seen in other biological systems such as dictyostelids, social amoeba known to form multicellular aggregates observed as slugs under starvation conditions.…”

Genetic and clinical characterization of Niemann-Pick disease type C with homozygous NPC1 gene mutation: insights from whole exome sequencing and advanced neuroimaging of two famil...
Published 2024-02-01“…Conclusion: These cases underscore the critical role of genetic testing, particularly whole exome sequencing, in diagnosing NPC, which can often present with diverse clinical symptoms. The familial clustering observed also draws attention to the genetic counseling needs in populations with high rates of consanguinity, emphasizing the importance of community genetic studies to understand and manage such rare disorders. …”

Evolutionary plasticity in nematode Hox gene complements and genomic loci arrangement
Published 2024-11-01“…Here, we explored Hox gene complements in high-quality genomes of 80 species from all major clades of Nematoda to understand the evolution of this key set of body pattern genes and especially to probe the origins of the “dispersed” cluster observed in C. elegans. We also included the recently available high-quality genomes of some Nematomorpha as an outgroup. …”
