Carbonate Chemistry in Groundwater and Rivers Draining to the Baltic Sea: Implications for Coastal Ocean AcidificationNARA Subscribed
Terrestrial inputs can alter total alkalinity (TA) and dissolved inorganic carbon (DIC) of the coastal ocean and modify seawater pH. Here, we first characterize the carbonate system in river and groundwater draining to the Baltic Sea using observations of TA, DIC, δ 13 C-DIC, and major ions across 6 countries and 17 beaches. We then assess whether submarine groundwater discharge (SGD) may impact coastal acidification. TA and D...
Features of possible regional ionospheric memory manifested themselves at low-latitudes under solar eclipse conditions.
Confirmed Outbreaks of Streptococcosis Caused by Streptococcus agalactiae Serotype Ia in Nile Tilapia Culture From Campeche, MexicoNARA Subscribed
Streptococcus agalactiae was confirmed as the etiologic agent of streptococcosis in Nile tilapia ( Oreochromis niloticus ) from Campeche, Mexico, during a cross‐sectional investigation of eight semi‐intensive farms (2021–2022) that yielded virulent strains in a challenge assay. Standard bacteriology, histopathology, API‐20 Strep phenotyping, one‐step PCR, and real‐time PCR confirmed S. agalactiae in five farms (62.5%). Gross a...
Length-Based Stock Assessment of Six Shallow-Water Demersal Fishes in the Colombian Caribbean SeaOA Marine
Scientific knowledge-based fishery management is essential to ensure the sustainability of marine resources, particularly in regions where fisheries are data-limited. This study assessed the stock status of six shallow-water demersal fish species (Bagre marinus, Cathorops mapale, Diapterus rhombeus, Eucinostomus argenteus, Haemulopsis corvinaeformis, and Lutjanus synagris) in the Colombian Caribbean Sea using three complementa...
Invasive fungal infections (IFI) are a significant cause of morbidity and mortality in hematologic malignancy patients and hematopoietic cell transplant (HCT) recipients. Mold cholecystitis has rarely been described. We present a case of disseminated Lomentospora prolificans , that had recrudescence of symptoms with acute cholecystitis. Treatment included a temporary cholecystostomy and administration of the novel antifungal f...
Deacetylation and Mechanical Refining Pathway for the Bioconversion of Sugarcane BagasseNARA Subscribed
Advancing lignocellulose biorefining is imperative for the deployment of cellulosic (2G) biofuels. This work investigates the tailoring of the alkaline deacetylation and mechanical refining (DMR) pathway for the bioconversion of sugarcane bagasse. Experiments are conducted at laboratory and pilot scales, varying the pretreatment conditions (70–92 °C; 48–100 g NaOH /kg) and the mechanical refining technologies (PFI and disk ref...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Sustainable precision agriculture and artificial intelligence (AI) are transforming modern farming by enhancing resource efficiency, addressing climate challenges, and fostering sustainability. In Colombia, sugarcane cultivation is pivotal in the agricultural economy, particularly in the Cauca River Valley, a region grappling with climate variability and resource optimization challenges. This study introduces an innovative met...
Bison grazing increases grass foliar nutrients and drought tolerance at fine spatial scalesNARA Subscribed
Aims The American bison is often recognized as an ecological engineer because their grazing and wallowing behavior increases plant diversity and productivity. These disturbances increase spatial heterogeneity and can alter plant nutrient and water dynamics. We assessed how bison grazing and wallowing affect grass chemistry and physiology, and whether grass evolutionary legacies mediate species-specific responses. Methods We me...
