Proofs of two conjectures involving sums of normalized Narayana numbers
Demonstratio MathematicaNarayana numbers are well-known and have many applications in the field of combinatorics. The Narayana numbers form a triangular array, where the sum of the nth row is the nth Catalan number.

Limnology and Oceanography, EarlyView.Abstract Chlorophyll a is commonly used as a surrogate for algal biomass in lakes and oceans even though phytoplankton can readily adjust intracellular chlorophyll concentration to changes in the environment through a cellular process termed photoacclimation.

Global Change Biology, Volume 29, Issue 3, Page 719-730, February 2023., 2023 The constraint of temperature and radiation on vegetation productivity was estimated with the variable θ. Values of θ differ during the start and end of season (SoS and EoS), indicating that radiation constraints the trend towards longer growing seasons but differently during spring and autumn.

Light‐Activated Pharmacological Tools for Exploring the Cholinergic System
Medicinal Research Reviews, EarlyView.ABSTRACT Cholinergic transmission plays a critical role in both the central and peripheral nervous systems, affecting processes such as learning, memory, and inflammation. Conventional cholinergic drugs generally suffer from poor selectivity and temporal precision, leading to undesired effects and limited therapeutic efficacy. Photopharmacology aims to

Molecular Tools to Study and Control Dopaminergic Neurotransmission With Light
Medicinal Research Reviews, EarlyView.ABSTRACT Dopaminergic neurotransmission is involved in several important brain functions, such as motor control, learning, reward‐motivated behavior, and emotions. Dysfunctions of dopaminergic system may lead to the development of various neurological and psychiatric disorders, like Parkinson's disease, schizophrenia, depression, and addictions ...

A new approach to Catalan numbers using differential equations [PDF]
arXiv, 2016 In this paper, we introduce two differential equations arising from the generating function of the Catalan numbers which are `inverses' to each other in some sense. From these differential equations, we obtain some new and explicit identities for Catalan and higher-order Catalan numbers.

PLANTS, PEOPLE, PLANET, EarlyView.The phenomenon of “Plant Awareness Disparity”—often defined as people's inability to notice, recognize, and appreciate plants and their significance—has been described as one of the greatest challenges that botanists face in our joint mission to address the social‐ecological crisis of our time.

Response of Amblyseius swirskii to deltamethrin
Pest Management Science, EarlyView.The analysis of toxicological and molecular data reveals target‐site as well as metabolic modifications associated with the resistance to deltamethrin in Amblyseius swirskii colonies. However, semi‐field assays show increased run‐off behavior after treatments with the same pesticide.
