Continuous Electronic Fetal Monitoring during Labor: A Critique and a Reply to Contemporary Proponents

The Surgery Journal, 2018
A half century after continuous electronic fetal monitoring (EFM) became the omnipresent standard of care for the vast majority of labors in the developed countries, and the cornerstone for cerebral palsy litigation, EFM advocates still do not have any ...

Bifurcation analysis of a semiconductor laser with filtered optical feedback [PDF]

, 2006
We study the dynamics and bifurcations of a semiconductor laser with delayed filtered optical feedback, where a part of the output of the laser reenters after spectral filtering. This type of coherent optical feedback is more challenging than the case of

Spin and exchange coupling for Ti embedded in a surface dipolar network [PDF]

, 2011
We have studied the spin and exchange coupling of Ti atoms on a Cu$_2$N/Cu(100) surface using density functional theory. We find that individual Ti have a spin of 1.0 (i.e., 2 Bohr Magneton) on the Cu$_2$N/Cu(100) surface instead of spin-1/2 as found by ...

Room-temperature ferromagnetism in graphite driven by 2D networks of point defects [PDF]

, 2009
Ferromagnetism in carbon-based materials is appealing for both applications and fundamental science purposes because carbon is a light and bio-compatible material that contains only s and p electrons in contrast to traditional ferromagnets based on 3d or

Exploring Peracetic Acid and Acidic pH Tolerance of Antibiotic-Resistant Non-Typhoidal Salmonella and Enterococcus faecium from Diverse Epidemiological and Genetic Backgrounds

Microorganisms, 2023
Acid stress poses a common challenge for bacteria in diverse environments by the presence of inorganic (e.g., mammals’ stomach) or organic acids (e.g., feed additives; acid-based disinfectants). Limited knowledge exists regarding acid-tolerant strains of

Scanned Probe Microscopy of Electronic Transport in Carbon Nanotubes

, 2000
We use electrostatic force microscopy and scanned gate microscopy to probe the conducting properties of carbon nanotubes at room temperature. Multi-walled carbon nanotubes are shown to be diffusive conductors, while metallic single-walled carbon ...

Whole-genome long-read sequencing to unveil Enterococcus antimicrobial resistance in dairy cattle farms exposed a widespread occurrence of Enterococcus lactis

Microbiology Spectrum
Enterococcus faecalis (Efs) and Enterococcus faecium (Efm) are major causes of multiresistant healthcare-associated or nosocomial infections. Efm has been traditionally divided into clades A (healthcare associated) and B (community associated) but clade ...

Electrochemical and Density Function Theory Investigations of L- Arginine as Corrosion Inhibitor for Steel in 3.5% NaCl

International Journal of Electrochemical Science, 2013
The corrosion inhibition effect of L-arginine has been used as corrosion inhibitor for steel in 3.5 % NaCl. In this study, electrochemical frequency modulation, EFM was used as an effective method for corrosion rate determination.

First principles investigation of transition-metal doped group-IV semiconductors: R${_x}$Y$_{1-x}$ (R=Cr, Mn, Fe; Y=Si, Ge)

, 2005
A number of transition-metal (TM) doped group-IV semiconductors, R$_{x}$Y$_{1-x}$ (R=Cr, Mn and Fe; Y=Si, Ge), have been studied by the first principles calculations.
