Effect of Climate Changes, Induced Risks, and Oil Price Appreciation on Energy Stock Returns in World Markets

open access: yesInternational Studies of Economics, EarlyView.
ABSTRACT This study examines the impact of climate policy uncertainty (CPU) on world energy stock returns. Evidence shows that a rise in CPU causes stocks to plummet in individual countries, regions, and the world energy stock markets. The negative effects are also exhibited in climate induced risks, the covariance between a change in CPU and equity ...

Machine learning approach to study microboring assemblage dynamics in two living massive coral genera

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The coral host comprises various microorganisms including those living in its skeleton. In coral skeletons, bioeroding microflora (cyanobacteria, algae, and fungi), which play an important role in reefs and coral resilience, produce specific traces (microborings) by actively dissolving the carbonate.

Exploiting algal strains for robust cross‐domain phytoplankton classification via deep learning

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Phytoplankton species are essential bioindicators for evaluating the status of freshwater ecosystems in accordance with the EU Water Framework Directive. However, manual identification of phytoplankton is time‐consuming and requires taxonomic expertise. Deep learning (DL) offers promising tools for automating the identification, but challenges

Rough Quasi‐Conformal Mapping for Realizing Omnidirectional Light Wave Manipulation in Lower‐Index Meta‐Lens

open access: yesLaser &Photonics Reviews, EarlyView.
A rough quasi‐conformal mapping strategy breaks the rigid geometric constraints of transformation optics. By trading perfect local angle preservation for a dramatically reduced refractive index, this design paradigm enables the creation of ultra‐flat, wide‐angle, and even omnidirectional lenses that are both high‐performance and manufacturable, opening

Mechanically Tunable DNA Hydrogels as Prospective Biosensing Modules

open access: yesMacromolecular Rapid Communications, EarlyView.
Sequence‐programmable and thermally responsive DNA hydrogels enable highly sensitive mechanical biosensing through the exchange of linker strands using a toehold strand displacement mechanism. This new type of mechanical biosensor has in‐built sequence‐specificity and dose‐sensitivity, obviating the need for elaborate DNA sequencing and enabling rapid ...
