Forecasting Volatility of Commodity, Currency, and Stock Markets: Evidence From Markov‐Switching Multifractal Models

Journal of Forecasting, Volume 45, Issue 6, Page 2905-2941, September 2026.
ABSTRACT This paper adopts a bivariate Markov‐switching multifractal (BMSM) model to reexamine comovement in SV between commodity, foreign exchange (FX), and stock markets. After the 2007–2008 global financial crisis understanding volatility linkages and the correlation structure between these markets becomes very important for risk analysts, portfolio

Fractal Generation via CR Iteration Scheme With S-Convexity

IEEE Access, 2019
The visual beauty, self-similarity, and complexity of Mandelbrot sets and Julia sets have made an attractive field of research. One can find many generalizations of these sets in the literature.

On the Evolution of the Stock Market Efficiency: Evidence From Emerging Markets

International Studies of Economics, Volume 21, Issue 3, Page 281-293, September 2026.
ABSTRACT The study of market efficiency is one of the most covered topics in the field of financial markets, with the Efficient Market Hypothesis gathering devotees as well as several critics. The perception of markets as agents with an adaptive nature gave rise to the Adaptive Market Hypothesis (AMH).

Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

Land Degradation &Development, Volume 37, Issue 13, Page 9126-9143, 15 August 2026.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Calculation of the Structure of a Shrub in the Mandelbrot Set

Discrete Dynamics in Nature and Society, 2011
We calculate the external arguments of the structure of any shrub in the Mandelbrot set. Before calculating, we revise, expand, and clarify some tools useful for this paper: harmonics, pseudoharmonics, the concept of structure, the structure of a shrub ...

Recipient Selection and Outcomes After Out‐of‐Sequence Kidney Allocation Since Implementation of Kidney Allocation System 250 (KAS250): A Single‐Center Experience

Clinical Transplantation, Volume 40, Issue 8, August 2026.
ABSTRACT Introduction Allocation out of sequence (AOOS) of kidneys has increased after KAS250 and raised concerns regarding transparency and equitable recipient selection. Less is known about recipient selection and outcomes at individual centers. Methods We performed a single‐center retrospective study of adult deceased donor kidney transplants at the

A Novel Multiband Fractal Antenna Based on Three-Dimensional Mandelbrot-Set Structure

IEEE Open Journal of Antennas and Propagation
Mandelbrot fractals are a class of geometric structures characterized by non-integer dimensions, whose unique quasi-self-similarity provides fractal antennas with enhanced electrical lengths and diverse electromagnetic properties.

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

Journal 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 ...

An Effective Iterative Process Utilizing Transcendental Sine Functions for the Generation of Julia and Mandelbrot Sets

Fractal and Fractional
This study presents an innovative iterative method designed to approximate common fixed points of generalized contractive mappings. We provide theorems that confirm the convergence and stability of the proposed iteration scheme, further illustrated ...
