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.

Harnessing iEcology data to uncover invasive species behaviour

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1022-1031, April 2026.
Abstract Invasive animal species threaten ecosystems, biodiversity and human livelihoods. Behavioural traits such as boldness, exploratory tendencies, learning ability and social interactions are known to influence invasion success. Yet these behavioural traits remain underexplored due to challenges in observing behaviour across large spatial and ...

DysRegNet: Patient‐specific and confounder‐aware dysregulated network inference towards precision therapeutics

British Journal of Pharmacology, Volume 183, Issue 8, Page 1709-1724, April 2026.
Abstract Background and Purpose Gene regulation is frequently altered in diseases in unique and patient‐specific ways. Hence, personalised strategies have been proposed to infer patient‐specific gene‐regulatory networks. However, existing methods do not scale well because they often require recomputing the entire network per sample.

Urban birds' detectability is affected by inter‐ and intraspecific variation in shyness

Ibis, Volume 168, Issue 2, Page 711-722, April 2026.
Detection probabilities differ between bird species as a function of their life history and ecological and behavioural traits, inevitably introducing bias in their abundance and occupancy estimates. However, the effects of behavioural traits such as species shyness and vigilance on detectability remain poorly understood.

Simple Python‐based methods for analysis and drift‐correction of STM images

Journal of Microscopy, Volume 302, Issue 1, Page 39-49, April 2026.
Abstract A successful scanning tunnelling microscopy (STM) experiment relies on both delicate sample preparation and measurement, and careful image filtering and analysis to provide clear and solid results. Processing and analysis of STM images may result in a tricky task, due to the complexity and specificity of the probed systems.

Photochemical Cyclization of Tertiary Buta‐2,3‐dienamides to β‐Lactams Upon Triplet Energy Transfer

Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.
Energy transfer is the key to the successful photocyclization of the title compounds to 3,4‐disubstituted 2‐azetidinones. If the substituent at the nitrogen atom is primary (R2 = H), trans products are formed exclusively. The triplet state of xanthen‐9‐one (XT) was found to be quenched by an allene amide (R, R2 = H, R1 = Bn, and R3 = Ph) with a ...
