Using structured decision making with landowners to address private forest management and parcelization: balancing multiple objectives and incorporating uncertainty

Ecology and Society, 2015
Parcelization and forest fragmentation are of concern for ecological, economic, and social reasons. Efforts to keep large, private forests intact may be supported by a decision-making process that incorporates landowners' objectives and uncertainty.

Structural Characterization of Chemical Compounds Based on Their Fragmentation Rules in Sophorae Fructus by UPLC-QTOF-MS/MS

Pharmaceutical Fronts, 2022
This study aims to identify the chemical components in Sophorae Fructus, and explore the mass spectrometric cleavage rules using the UPLC-Q-TOF-MS/MS method. The main characteristic fragments of the compounds were analyzed by electrospray ionization (ESI)

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

The Impact of Flow Velocity on Environmental DNA Detectability for the Application in River Systems

Environmental DNA
Organisms perpetually release genetic material in their surroundings, referred to as environmental DNA (eDNA), which can be captured and subsequently analyzed to detect biodiversity across the tree of life. In lotic, dynamic environments, little is known

Lack of Agreement on Fragmentation Metrics Blurs Correspondence between Fragmentation Experiments and Predicted Effects

Ecology and Society, 2003
The direct correspondence between landscape fragmentation and its effects is still the subject of debate. Many widely accepted hypotheses are not supported by experiments. The issue of fragmentation measurement is addressed here.

Mass Spectrometric Calibration Procedure for Real-Time Detection of Lighter Hydrocarbons

Energies, 2021
Determining gas compositions from live well fluids on a drilling rig is critical for real time formation evaluation. Development and utilization of a reliable mass spectrometric method to accurately characterize these live well fluids are always ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
