Relationships between acoustic scattering layers and ocean stratification: An acoustic approach to estimate mixed layer depth

Limnology and Oceanography: Methods, Volume 24, Issue 3, March 2026.
Abstract Ocean stratification, measured as mixed layer depth (MLD), is an important feature that influences many processes in the ocean; for example, by mediating the fluxes of momentum, heat and crucially key gases such as CO2 and oxygen from the atmosphere into the water column and vice versa. The conventional methods to measure stratification (e.g.,

Dose‐Dependent Effects of Biochar on Soil Revealed by Fast Field‐Cycling (FFC) NMR: From Molecular Water Dynamics to Soil Functionality

Magnetic Resonance in Chemistry, Volume 64, Issue 3, Page 349-364, March 2026.
Dose–response of biochar in a clay soil: fifteen mixtures (fBC 0–1) reveal nonlinear thresholds (pH/EC) and sharp WHC gains near fBC ≈ 0.3–0.5. Coupled FT‐IR and FFC‐NMR (0.01–10 MHz; ModelFree τc distributions) link water dynamics to soil functionality.

Short‐term responses in weed spatial patterns during early adoption of conservation agriculture practices

Pest Management Science, Volume 82, Issue 3, Page 2627-2638, March 2026.
Weed spatial patterns and temporal stability were shaped by species life forms and the cropping systems implemented in the plots. Weed aggregation was more pronounced in conservation agriculture and among perennials. Patch stability was primarily governed by species life form and was stronger among perennials. Abstract BACKGROUND The aggregated spatial

Massive Spanning Forests on the Complete Graph: Exact Distribution and Local Limit

Random Structures &Algorithms, Volume 68, Issue 2, March 2026.
ABSTRACT We provide new exact formulas for the distribution of massive spanning forests on the complete graph, which give also a new outlook on the celebrated special case of the uniform spanning tree. As a corollary we identify their local limit. This generalizes a well‐known theorem of Grimmett on the local limit of uniform spanning trees on the ...

Synthetic Cells on Demand: From Molecular Stimuli to Cellular Functions

ChemSystemsChem, Volume 8, Issue 2, March 2026.
ABSTRACT Synthetic cells constructed via bottom‐up approaches using lipid or polymer vesicles have become essential tools for mimicking cellular functions and studying synthetic biological systems. These vesicles can undergo morphological changes and trigger internal reactions in response to external stimuli, such as osmotic pressure, temperature, pH ...

Valor nutritivo del ensilaje de avena (Avena sativa L.).

, 2018
Se realizó un ensayo para determinar el valor nutritivo del ensilaje de avena. Fueron usados 9 animales ovinos de la raza Romey marsh mestizos, de 795 días de edad promedia y con un peso de 50 kg al iniciar el ensayo. El experimento de dividió en 4 períodos para toma de muestras y 4 períodos de descanso, cada uno de los períodos comprendía, un lapso de
