Multifractal Analysis of Hydrologic Data Using Wavelet Methods and Fluctuation Analysis

Discrete Dynamics in Nature and Society, 2017
We study the multifractal properties of water level with a high-frequency and massive time series using wavelet methods (estimation of Hurst exponents, multiscale diagram, and wavelet leaders for multifractal analysis (WLMF)) and multifractal detrended ...

Socially Responsible Investors and Corporate Resistance to Climate Disruptions: Agents of Change or Passive Participants?

Accounting &Finance, EarlyView.
ABSTRACT Climate change is a global challenge with far‐reaching implications for firms and capital markets. This study examines whether ownership by socially responsible investors (SRIs) enhances firms' resilience to climate shocks. Focusing on transition and physical climate risks, we analyse whether SRI ownership reduces firms' stock return ...

Macro‐ and microcirculatory factors affecting foot temperature change during walking

Experimental Physiology, EarlyView.
Abstract Change in skin temperature is a complex process affected by several factors. During walking, increased microcirculatory activity, such as muscle metabolism, could increase foot temperature. The ensuing macrocirculatory responses, such as increased leg blood flow (LBF), might also increase foot temperature.

From Marginal to Central: Marginal Zone‐like B Cells as Critical Targets in Cladribine‐Treated Multiple Sclerosis

Annals of Neurology, Volume 100, Issue 4, Page 808-823, October 2026.
Objective Multiple sclerosis (MS) is a chronic autoimmune disease where B cells play a central pathogenic role. Cladribine, an oral therapy, provides durable benefits by reshaping lymphocyte populations, yet its specific long‐term impact on distinct B‐cell subsets is not fully understood.

A Wavelet‐Based Framework for Mapping Long Memory in Resting‐State fMRI: Age‐Related Changes in the Hippocampus From the ADHD‐200 Dataset

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
We propose a new wavelet‐based Bayesian framework to analyze long‐memory properties of resting‐state fMRI signals and their relationship to clinical covariates. Applying this to the ADHD‐200 dataset, we found that in children, age is positively associated with the long‐memory parameter in hippocampal regions.

Preparation and Characterization of Azelaic Acid‐Loaded Nanofiber Scaffold as Anti‐Acne and Depigmenting Care, Fabricated by Electrospinning Method

Journal of Cosmetic Dermatology, Volume 25, Issue 10, October 2026.
ABSTRACT Objective Acne vulgaris is a common dermatological concern, and conventional topical azelaic acid formulations may have limitations in skin residence time and tolerability. Polymeric nanofiber scaffolds offer a promising platform for topical drug delivery.

OCO‐3 Meets ECOSTRESS: Insights Into Ecosystem Diurnal Water‐Use Efficiency From Co‐Located Solar‐Induced Fluorescence and Thermal Observations

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Terrestrial ecosystem regulation of carbon and water fluxes is critical for constraining climate–biosphere feedbacks but remains poorly quantified across space and time. Here, we evaluate whether co‐located observations from NASA's Orbiting Carbon Observatory‐3 (OCO‐3) and the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station
