Food-anticipatory activity in Syrian hamsters: behavioral and molecular responses in the hypothalamus according to photoperiodic conditions. [PDF]

open access: yesPLoS ONE, 2015
When food availability is restricted, animals adjust their behavior according to the timing of food access. Most rodents, such as rats and mice, and a wide number of other animals express before timed food access a bout of activity, defined as food ...

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

open access: yesAdvanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

Energy‐Efficient, Sustainable Cascade Glucose Electrooxidation into Glucaric Acid

open access: yesAdvanced Materials, EarlyView.
This study presents a tandem system that efficiently converts glucose into glucaric acid while generating renewable electricity. By decoupling the oxidation process into two cascaded steps, the system achieves an overall 90% Faradaic efficiency and 80% conversion efficiency at ∼0.6 VRHE, significantly reducing energy consumption compared to traditional

Krichever Maps, Faa' di Bruno Polynomials, and Cohomology in KP Theory

open access: yes, 1997
We study the geometrical meaning of the Faa' di Bruno polynomials in the context of KP theory. They provide a basis in a subspace W of the universal Grassmannian associated to the KP hierarchy.

BioCNTs Mediated Delivery of Systemically Mobile Small RNAs via Leaf Spray to Control Both Tomato DNA and RNA Viruses

open access: yesAdvanced Science, EarlyView.
A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.

Amino acid and N mineralization dynamics in heathland soil after long-term warming and repetitive drought [PDF]

open access: yesSOIL, 2015
Monomeric organic nitrogen (N) compounds such as free amino acids (FAAs) are an important resource for both plants and soil microorganisms and a source of ammonium (NH4+) via microbial FAA mineralization.

Identification of free amino acids (FAA) that are important as major intracellular osmolytes in the estuarine Hong Kong oyster, Crassostrea hongkongensis

open access: yesAquaculture Reports, 2023
Crassostrea hongkongensis (Hong Kong oyster), a commercially valuable bivalve thriving in the estuaries along the northern coast of the South China Sea, is threatened by the increase of salinity during the dry season. It is essential to improve its hyper-
