Assessing Seasonal Effects on Identification of Cultivation Methods of Short–Growth Cycle Brassica chinensis L. Using IRMS and NIRS

open access: yesFoods
Seasonal (temporal) variations can influence the δ13C, δ2H, δ18O, and δ15N values and nutrient composition of organic (ORG), green (GRE), and conventional (CON) vegetables with a short growth cycle.

Linear circuit models for on-chip quantum electrodynamics

open access: yes, 2011
We present equivalent circuits that model the interaction of microwave resonators and quantum systems. The circuit models are derived from a general interaction Hamiltonian.

Stable Carbon and Nitrogen Isotope Analysis Explores Diverse Domestic Goose Management Practices in Medieval and Postmedieval Russia

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Studying goose domestication through archaeological finds has been challenging due to the similar skeletal morphology of the European domestic goose and its wild progenitor, the greylag goose (Anser anser). We analyzed stable carbon (δ13C) and nitrogen (δ15N) isotopes from bone collagen of subfossil domestic and potentially domestic geese to ...

An Automatic Injection Device and the Method for Carbon and Oxygen Isotopes Analyses of Carbon Monoxide

open access: yesZhipu Xuebao
Carbon monoxide (CO) is an essential component of air, and it arises from anthropogenic sources and natural sources. These different sources of CO have significant differences in carbon and oxygen isotopic values, therefore the carbon and oxygen isotopic

Theoretical and experimental study of AC loss in HTS single pancake coils

open access: yes, 2008
The electromagnetic properties of a pancake coil in AC regime as a function of the number of turns is studied theoretically and experimentally. Specifically, the AC loss, the coil critical current and the voltage signal are discussed.

SPROUTS_DB: An Implemented Database of Contaminants for Extracellular Vesicle Proteomics Studies

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Current proteomics techniques allow rapid identification and quantification of proteins within any given biological source. However, LC–MS/MS proteomics is vulnerable to laboratory and sample‐associated contaminants. Therefore, accurate identification and annotation of such contaminants is crucial for development of reliable databases ...

Working standards and analytical framework for CSIA: isotopic composition (δ13C, δ15N, and δ34S) of 21 amino acids and 7 nucleobases

open access: yesProgress in Earth and Planetary Science
We determined the carbon and nitrogen isotope compositions of biologically important 21 amino acids and 7 nucleobases, which are used as working standards. These isotopic compositions were determined using a high-sensitivity elemental analyzer coupled to

Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

open access: yesPest Management Science, EarlyView.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the

Giant magnetoimpedance: new electrochemical option to monitor surface effects?

open access: yes, 2006
Magnetoimpedance, MI, change due to surface modification of the sensitive element caused by biofluids was studied with the aim of creating a robust sensor capable of separating the chemical surface modification from the sensing process.

Corn rootworm (Coleoptera: Chrysomelidae) emergence patterns, survival, and injury in blended refuges and pure stands of short‐stature corn and tall corn

open access: yesPest Management Science, EarlyView.
Graphical Abstract Text: This study compared corn rootworm (Diabrotica spp.) emergence patterns and injury between short‐stature corn and tall corn to help inform corn rootworm management strategies in short‐stature corn Abstract BACKGROUND Short‐stature corn became commercially available in the United States in 2025 and has several desirable qualities
