Phylogenetic analysis of the metazoan carotenoid oxygenase superfamily: a new ancestral gene assemblage of BCO-like (BCOL) proteins

open access: yesScientific Reports, 2017
Here we describe a new family of carotenoid cleavage oxygenases (CCOs) in metazoans, the BCO2-like (BCOL) clade, which contains lancelet, nematode, and molluscan carotenoid oxygenase sequences.

Phytoplankton Bloom Changes During Three Regime Shifts Derived From Sea Ice Concentration in the Ross Sea

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Sea Ice Concentration (SIC) plays an important role in the Antarctic polynyas, especially where biological interactions through changes in chlorophyll‐a concentration (CHL) phenology are concerned. To specifically understand how much SIC change affects CHL in the Ross Sea polynya (RSP), the regime shift index (RSI) was applied to the SIC ...

A novel, two-step top seeded infiltration and growth process for the fabrication of single grain, bulk (RE)BCO superconductors

open access: yes, 2016
A fundamental requirement of the fabrication of high performing, (RE)–Ba–Cu–O bulk superconductors is achieving a single grain microstructure that exhibits good flux pinning properties.

Phase Engineering of Nanogold: Non‐Close Packed Square Planes in A′B′ Stacking with a 0.5 Å Channel

open access: yesAdvanced Materials, Volume 38, Issue 8, 6 February 2026.
Gold is well known to adopt the face‐centered‐cubic (fcc) structure. This work presents an unusual non‐close‐packed phase attained in a 40‐atom gold nanocluster, which is in contrast with the close‐packed fcc quasi‐isomer. The non‐compact structure exhibits exclusive square planes in a layer‐by‐layer stacking, hence, possessing a unique 0.5 Å channel ...

Fuzzy Sets in Dynamic Adaptation of Parameters of a Bee Colony Optimization for Controlling the Trajectory of an Autonomous Mobile Robot

open access: yesSensors, 2016
A hybrid approach composed by different types of fuzzy systems, such as the Type-1 Fuzzy Logic System (T1FLS), Interval Type-2 Fuzzy Logic System (IT2FLS) and Generalized Type-2 Fuzzy Logic System (GT2FLS) for the dynamic adaptation of the alpha and beta

Comparing Minimally Lethal Sampling Methods for Genomics in the Eastern Oyster (Crassostrea virginica)

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Non‐lethal genotyping of oysters is challenging due to the invasive nature of traditional tissue sampling methods. We compared four different sampling techniques on juvenile Eastern oysters, monitoring survival and DNA quality and quantity to identify the optimal approach.

Novel Echocardiographic Index for Risk Stratification of Ventricular Arrhythmias and Mortality Based on Right Ventricular Function

open access: yesJournal of Arrhythmia, Volume 42, Issue 1, February 2026.
Patients undergoing ICD implantation with both preprocedural echocardiography and cardiac magnetic resonance (CMR) were retrospectively analyzed to assess right ventricular (RV) function. Echocardiographic RV fractional area change (RVFAC) and the contraction pressure index (CPI), as well as CMR‐derived RV ejection fraction (RVEF), predicted ...

Nutrient availability modulates impacts of short‐term shifts in temperature and grazing on phytoplankton composition and size structure

open access: yesLimnology and Oceanography, Volume 71, Issue 2, February 2026.
Abstract The significant contribution of phytoplankton to global primary production is regulated by several abiotic and biotic factors, which are often difficult to account for in natural systems. To address these challenges, we perturbed a summer plankton community from Narragansett Bay, Rhode Island, USA, by manipulating the temperature and nutrient ...

Annual Variability in Marine Particulate Trace Elements During the Hawaii Aerosol Time‐Series

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The Hawaii Aerosol Time‐Series (HATS) was a coordinated effort to simultaneously monitor atmospheric and water column dust dynamics in the North Pacific Subtropical Gyre. Throughout 2022 and 2023, HATS measured the composition of water column particles and made complementary measurements of aerosol chemistry and deposition fluxes.
