The Semantics of Article Acquisition [PDF]

open access: yes, 2019
Accurately using articles has consistently been a difficult task for English language learners as articles are often treated as solely grammatical forms rather than also recognizing as representatives of complex semantic properties.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Monitoring the Etching Process of Hi-Bi Fiber Through a Fiber Loop Mirror

open access: yesIEEE Photonics Journal, 2017
A method for monitoring the etching process of Hi-Bi fiber is proposed and demonstrated. The birefringence of the etching fiber is accurately calculated by tracking the shift of the interference spectrum in a high-birefringence fiber loop mirror ...

The Perception of Postalveolar English Obstruents by Spanish Speakers Learning English as a Foreign Language in Mexico

open access: yesLanguages, 2020
The present study deals with the perception (identification and discrimination) of an English phonemic contrast (/t∫/–/∫/, as in cheat and sheet) by speakers of two Mexican varieties of Spanish who are learning English as a foreign language.

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Real-time phase-selective data acquisition system for measurement of wave phenomena in pulsed plasma discharges [PDF]

open access: yes, 1998
A novel data acquisition system and methodology have been developed for the study of wave phenomena in pulsed plasma discharges. The method effectively reduces experimental uncertainty due to shot-to-shot fluctuations in high repetition rate experiments.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

open access: yesFEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.
