What do We Mean by Environmental Heterogeneity? Toward A Mechanistically Explicit and Scale‐Dependent Framework

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We synthesized 360 studies on environmental heterogeneity (EH) across taxa, regions, and disciplines. Only 10% of studies explicitly defined EH, and definitions were predominantly descriptive. We identify four operational interpretations of EH and propose a Research Roadmap linking EH metrics to five mechanistic hypotheses with testable predictions ...

Quantification of Wine Mixtures with an Electronic Nose and a Human Panel

Frontiers in Bioengineering and Biotechnology, 2018
In this work, an electronic nose and a human panel were used for the quantification of wines formed by binary mixtures of four white grape varieties and two varieties of red wines at different percentages (from 0 to 100% in 10% steps for the electronic ...

Population Genetics of Seriola lalandi Confirm Hemispheric Divergence and Reveal Genetic Structure in the Temperate Northern Pacific and Between Wild and Captive‐Reared Fish

Ecology and Evolution, Volume 16, Issue 8, August 2026.
We investigated the genetic diversity and population structure of Seriola lalandi across the Pacific Ocean, including wild and captive‐reared individuals. Our results revealed pronounced hemispheric genetic differentiation and previously undetected substructure within the Temperate Northern Pacific, along with consistent differences between wild and ...

Enrichment of Gluten‐Free Fresh Pasta With Cricket Flour: Technological and Nutritional Quality

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Gluten‐free fresh pasta was formulated with increasing levels of Acheta domesticus flour (0%–10%). Nutritional composition, cooking performance, color, texture, and in vitro digestibility were evaluated. Consumer perception revealed acceptable sensory quality up to 5.8% inclusion, highlighting cricket flour as a promising ingredient for protein ...

Rituximab Binding Endows CD20+ Extracellular Vesicles With NK Cell‐Activating Properties in B Cell Lymphoma

Journal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
B cell lymphoma‐derived EVs are intrinsically neutral or suppressive with respect to NK cell activity (panel 1). In the context of rituximab treatment, NK cytotoxicity is enhanced by antibody‐dependent cell‐mediated cytotoxicity (panel 2). Herein we show that, in addition, rituximab recognition of EV‐associated CD20 generates immune complexes that ...

Intrinsic Shape LDA With Application to Body Human Shapes Classification

Statistical Analysis and Data Mining: An ASA Data Science Journal, Volume 19, Issue 4, August 2026.
ABSTRACT Advancements in 3D scanning and cloud infrastructure enable the acquisition and analysis of high‐density body surface datasets. In this work, we propose a novel methodology that extends linear discriminant analysis (LDA) to Kendall's shape space for the classification of 3D objects, specifically human body shapes.
