Fleet Behaviour Under Economic Uncertainty: Multi‐Species Policy Scenarios for the Purse‐Seine Fishery

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Managing fishing effort remains a central challenge in achieving sustainability in many fisheries, particularly where high‐value species attract intense competition. In the Indian Ocean tropical tuna fishery, understanding how fishers respond to changing bio‐economic conditions is essential for developing effective management.

Listening to tuna: Acoustic characterization of captive juvenile yellowfin tuna (Thunnus albacares)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The effectiveness of passive acoustic monitoring (PAM) for studying marine biodiversity highly relies on comprehensive libraries of species‐specific sounds. While sound production is well‐documented in reef and freshwater fishes, the acoustic behaviour of ecologically and economically vital pelagic species like tunas still remains largely ...

Performance of grain sorghum hybrids in soils with low and high aluminum saturation

open access: yesPesquisa Agropecuária Tropical, 2018
The presence of aluminum (Al3+) in acidic soils is one of the main causes of low crop yield, since it inhibits the root growth, thus affecting the nutrients and water uptake by plants.

Inverse problems for semilinear elliptic PDE with a general nonlinearity a(x,u)$a(x,u)$

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract This article studies the inverse problem of recovering a nonlinearity in an elliptic equation Δu+a(x,u)=0$\Delta u + a(x,u) = 0$ from boundary measurements of solutions. Previous results based on first‐order linearization achieve this under a sign condition on ∂ua(x,u)$\partial _u a(x,u)$, and results based on higher order linearization ...

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 10, Page 2291-2369, October 2026.
ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

Behavioral Response of Arctocephalus australis to Pedestrian Disturbance During the Breeding Season: Implications for Wildlife Tourism Management

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The South American fur seal (Arctocephalus australis) breeds in dense colonies along the Peruvian coast, mostly within protected areas managed by the Servicio Nacional de Áreas Naturales Protegidas por el Estado (SERNANP). To support responsible wildlife tourism near breeding sites, we evaluated the behavioral responses to controlled ...

Sete leccións da COVID [PDF]

open access: yesBoletín das Ciencias, 2021
O 11 de marzo de 2020, a Organización Mundial da Saúde (OMS) declara pandemia a infección causada polo SARS-CoV-2. Hoxe pode anunciarse que xamais na historia da ciencia houbo tanto coñecemento acumulado sobre un virus aos poucos meses de descubrirse; pero a epidemioloxía, como calquera ciencia, necesita tempo para repetir os experimentos e confirmar ...

Wärmeträgerflüssigkeiten als Co‐Diluenten in lokal hochkonzentrierten Elektrolyten für schnellladefähige Lithium‐Metall‐Batterien mit erhöhter Sicherheit

open access: yesAngewandte Chemie, Volume 138, Issue 34, 17 August 2026.
Zwei fluorierte Ether aus dem Bereich der Wärmeträgerflüssigkeiten werden als Co‐Diluenten in lokal hochkonzentrierten Elektrolyten für lithiummetallbasierte Batterien eingesetzt. Die ternäre Diluentenmischung erhöht die Ionenmobilität, senkt die Überspannung und verbessert so coulombische Effizienz und Lebensdauer der Zelle bei hohen Stromdichten, was
