The Epidemiology of Sickle Cell Disease in Sub‐Saharan Africa: Current Knowledge and Gaps to be Filled

American Journal of Hematology, Volume 101, Issue S1, Page 5-16, April 2026.
What are the available data on incidence & prevalence prognosis risk factors of severity of sickle cell disease in sub‐Saharan Africa? ABSTRACT Sickle Cell Disease (SCD) is highly prevalent in sub‐Saharan Africa. Epidemiological data remain sparse, but regional screening and research initiatives are expanding.

A Fuzzy Framework for Realized Volatility Prediction: Empirical Evidence From Equity Markets

Journal of Forecasting, Volume 45, Issue 3, Page 1261-1291, April 2026.
ABSTRACT This study introduces a realized volatility fuzzy time series (RV‐FTS) model that applies a fuzzy c‐means clustering algorithm to estimate time‐varying c latent volatility states and their corresponding membership degrees. These memberships are used to construct a fuzzified volatility estimate as a weighted average of cluster centroids.

Microstructural and Thermal Evolution of Turbostratic and Crystalline hBN Using SPS With In‐Situ YAG

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
hBN ceramics with an in‐situ formed YAG phase were fabricated by SPS using turbostratic and crystalline powders. The results show that the microstructure, textural orientation, and functional properties of hBN ceramics can be significantly controlled by sintering temperature, starting powder structure, and additives.

Evolution of Open Magnetic Flux During Substorms: The Effects of Dipole Tilt Angle

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract There is a long‐standing debate on the causes of the semiannual variation of geomagnetic activity. One of the prevailing hypotheses is that the Earth's dipole tilt angle Ψ ${\Psi }$ modulates the dayside reconnection rate, causing the so‐called equinoctial effect. Here we perform the first large‐scale statistical study to test this hypothesis.

Dissolution Study of Biodegradable Magnesium Silicide Thin Films for Transient Electronic Applications

Advanced Science, Volume 13, Issue 15, 13 March 2026.
Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

Accelerated 3D MRI for ARIA monitoring in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract INTRODUCTION Amyloid‐targeting therapies for Alzheimer's disease require regular MRI monitoring for amyloid‐related imaging abnormalities (ARIA). 3D scans are more sensitive but time intensive; ultra‐fast implementations could improve access and reduce burden.

Information‐Driven Modeling of Energy Markets: An Unbalanced Wasserstein Barycenter Approach

Applied Stochastic Models in Business and Industry, Volume 42, Issue 2, March/April 2026.
ABSTRACT A novel methodology is proposed for jointly modeling the price dynamics of natural gas and electricity by integrating graph‐based Machine Learning and optimal transport theory. The framework combines visibility graph embeddings with the Wasserstein barycenter to uncover latent structures and asymmetric dependencies between the two ...

Population Pharmacokinetics and Exposure–Response Analyses of Momelotinib, Its Active Metabolite (M21), and Total Active Moiety in Myelofibrosis

Clinical Pharmacology &Therapeutics, Volume 119, Issue 3, Page 629-640, March 2026.
Momelotinib, a Janus kinase (JAK) 1/JAK2/activin A receptor type 1 inhibitor, is approved for the treatment of myelofibrosis with anemia. These analyses characterized the population pharmacokinetics of momelotinib and its active metabolite M21 following administration of the commercial tablet formulation in patients with myelofibrosis from phase II/III
