Disaster avoided: current state of the Baltic Sea without human intervention to reduce nutrient loads

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Excessive nutrient inputs have caused eutrophication of coastal ecosystems worldwide, triggering extensive algal blooms, oxygen‐depletion, and collapse of local fisheries. In the Baltic Sea, inputs of nitrogen (N) and phosphorus (P) have been significantly reduced since the 1980s, but the environmental state shows little to no signs of ...

An ant colony genetic fusion routing algorithm based on soft define network

open access: yesIET Networks, EarlyView., 2022
Abstract Aiming at the problem that there are many paths in data forwarding in soft define network (SDN) network, and the optimal path is difficult to find, combined with the advantages of ant colony algorithm and Genetic algorithm (GA), a routing control strategy based on the ant colony genetic fusion algorithm is proposed.

Effect of gap size on flange face corrosion

open access: yesMaterials and Corrosion, EarlyView.
This study investigates the effect of gap size on the flange face corrosion behavior in bolted flanged joints of wind turbine towers exposed to challenging offshore conditions. Using electrochemical techniques, it finds that increasing the gap thickness accelerates the general corrosion rate and delays crevice corrosion initiation.

Unearthing the impact of earthquakes: A review of economic and social consequences

open access: yesJournal of Policy Analysis and Management, EarlyView.
Abstract The purpose of this paper is to offer a comprehensive overview of the socioeconomic effects of earthquakes. We begin with a thorough literature review. Following this, we assess policy measures taken in response to major earthquakes, drawing on existing research to formulate insights and recommendations that policymakers can use to effectively

Direct ink writing of piezoresistive isoprene rubber nanocomposites

open access: yesPolymer Composites, EarlyView.
Use of carbon nanoparticles as conductive fillers in an isoprene rubber matrix for piezoresistive sensors fabricated via direct ink writing. Abstract Despite the growing interest in flexible electronics and wearable sensors, research in piezoresistive polymer nanocomposites has stagnated in consideration of the polymer matrices, particularly in ...
