Fractals: An Eclectic Survey, Part-I

open access: yesFractal and Fractional, 2022
Fractals are geometric shapes and patterns that may repeat their geometry at smaller or larger scales. It is well established that fractals can describe shapes and surfaces that cannot be represented by the classical Euclidean geometry.

Investigation of Specific IgG‐Secreting Cells in Congenital Toxoplasmosis: The TOXODIAG Study

open access: yesJournal of Clinical Laboratory Analysis, Volume 40, Issue 14, July 2026.
This study addressed the difficulty of establishing a postnatal biological diagnosis of congenital toxoplasmosis, particularly in the absence of toxoplasmosis monitoring during pregnancy, as is the case in many countries. Our work presents an ELISPOT (Enzyme‐Linked Immunospot) method adapted for the detection of B lymphocytes primed to produce IgG ...

HOMEOMORPHISMS BETWEEN LIMBS OF THE MANDELBROT SET [PDF]

open access: yes, 2012
We prove that for every hyperbolic component of the Mandelbrot set, any two limbs with equal denominators are homeomorphic so that the homeomorphism preserves periods of hyperbolic components.

How Long Is the Coast of Quantum Chemistry? Or, How to Evaluate Density Functional Theory as a Scientific Revolution

open access: yesNatural Sciences, Volume 6, Issue 3, July 2026.
Within quantum chemistry, density functional theory (DFT) is a revolution. This serves as an example of a multitude of other scientific events, supporting the idea that revolutions are always large, if observed with the appropriate magnification. ABSTRACT Distinguishing scientific revolutions from normal science is a subjective, conflicting matter ...

The Mandelbrot Set, Theme and Variations [PDF]

open access: yes, 2000
The Mandelbrot set is a fractal shape that classifies the dynamics of quadratic polynomials. It has a remarkably rich geometric and combinatorial structure.

On the Stability Domain of a Class of Linear Systems of Fractional Order

open access: yesFractal and Fractional, 2022
In this paper, the shape of the stability domain Sq for a class of difference systems defined by the Caputo forward difference operator Δq of order q∈(0,1) is numerically analyzed.

Generalized Scaling of Blue Metabolism in River Basins

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract River networks play a central role in regulating biogeochemical transformations at the catchment scale, yet a general scaling theory linking network structure to integrated metabolic function is still lacking. By positing the fundamental differences between blue (fluvial) and green (terrestrial) metabolisms in river basins, we focus on the ...

Pretransplant Malnutrition Risk Components are Associated With Adverse Outcomes After Simultaneous Pancreas and Kidney and Solitary Pancreas Transplantation

open access: yesClinical Transplantation, Volume 40, Issue 7, July 2026.
ABSTRACT Background Malnutrition is common among patients with end‐organ disease. The impact of any criterion of malnutrition (weight loss, muscle depletion, fat depletion, inadequate oral intake, or reduced functionality) pretransplant among simultaneous pancreas‐kidney (SPK) or solitary pancreas transplant (SPT) recipients is understudied.
