Using the diel cycle of ocean microbes to better understand their biogeochemical functions

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract The daily cycle of solar radiation has a profound influence in structuring the physiology of microbes in the euphotic zone and subsequently setting the degree of coupling across trophic levels within ocean ecosystems. There has been an upsurge of interest in the biological role of the diel cycle and the ability to probe it using molecular ...

Sunrise with Lincoln and Meanings with Chuck [PDF]

open access: yes, 2013
I walked 150 years on Monday. I walked across a great chasm of history. Physically, I walked from the Arlington Cemetery Metro Station across Memorial Bridge, then continued down the National Mall to 4th Street, where I witnessed one of the most peculiar

Identification and Biological Characterization of a Novel NRF2 Activator Molecule Released From the Membranes of Heat‐Treated Bifidobacterium breve NCC 2950

open access: yesMolecular Nutrition &Food Research, EarlyView.
We have shed light on the mode of action behind the postbiotic form of Bifidobacterium breve NCC 2950. Heat treatment of this strain at 90°C leads to the production of 4‐oxo‐2‐pentenoic acid (OPA), which activates NRF2 host response, improving oxidative stress resistance and decreasing inflammation. ABSTRACT Postbiotics are defined as a “preparation of

Evaluation of Varieties and Hybrids for Physico-Chemical Characters in Papaya (Carica papaya L.)

open access: yesJournal of Horticultural Sciences, 2013
Papaya (Carica papaya L., Caricaceae) is a fruit crop of commercial significance in tropical and subtropical regions of the world. The present investigation was carried out to assess physico-chemical characteristics of 10 genotypes of papaya under ...

Contrasting patterns of land use by resident and migratory bird assemblages in a tropical working landscape

open access: yesOikos, EarlyView.
The spatial configuration and management of agricultural and other land‐use practices can affect ecological assemblages. However, the differences in how resident and migratory birds respond to land‐use are remain unclear, hindering our understanding of bird biodiversity responses to land use.

Rapid estimation of minimum depth-to-bedrock from lidar leveraging deep-learning-derived surficial material maps

open access: yesApplied Computing and Geosciences, 2023
Previously glaciated landscapes often share similar surficial characteristics, including large areas of exposed bedrock, blankets of till deposits, and alluvium-floored valleys. These materials play significant roles in geologic and hydrologic resources,

A timid choice: risk‐taking behavior predicts individualized niche in a varying landscape of safety

open access: yesOikos, EarlyView.
Individual niche specialization predicts a match between an individual's phenotype and environment. Yet, whether animals achieve this match through phenotypic change (niche conformance) or by selecting the environment (niche choice), remains unexplored.

Lectures on configuration space methods for sunrise-type diagrams [PDF]

open access: yesarXiv, 2003
In this lecture series I will give a fundamental insight into configuration space techniques which are of help to calculate a broad class of Feynman diagrams, the sunrise-type diagrams. Applications are shown along with basic concepts and techniques.

Morphological properties of slender Ca II H fibrils observed by SUNRISE II

open access: yes, 2016
We use seeing-free high spatial resolution Ca II H data obtained by the SUNRISE observatory to determine properties of slender fibrils in the lower solar chromosphere.
