Transmission of Cytauxzoon felis to domestic cats by Amblyomma americanum nymphs

open access: yesParasites & Vectors, 2019
Background Successful Cytauxzoon felis transmission studies have occurred using Amblyomma americanum adults acquisition-fed as nymphs on an experimentally infected domestic cat or Dermacentor variabilis adults fed as nymphs on a splenectomized bobcat ...

Characterization of Acute and Chronic Hepatitis B Virus Genotypes in Canada. [PDF]

open access: yesPLoS ONE, 2015
OBJECTIVE:The prevalence and distribution of hepatitis B virus (HBV) genotypes in Canada is not known. Genotypic analysis may contribute to a better understanding of HBV strain distribution and transmission risk.

The Reliability Function of Lossy Source-Channel Coding of Variable-Length Codes with Feedback

open access: yes, 2019
We consider transmission of discrete memoryless sources (DMSes) across discrete memoryless channels (DMCs) using variable-length lossy source-channel codes with feedback. The reliability function (optimum error exponent) is shown to be equal to $\max\{0,

Epidemiological model for Clostridium difficile transmission in healthcare settings [PDF]

open access: yes, 2011
OBJECTIVE: Recent outbreaks of Clostridium difficile infection (CDI) have been difficult to control, and data indicate the importance of different sources of transmission may have changed. Our objectives were to evaluate the contributions of asymptomatic

Adenovirus Infections in African Humans and Wild Non-Human Primates: Great Diversity and Cross-Species Transmission

open access: yesViruses, 2020
Non-human primates (NHPs) are known hosts for adenoviruses (AdVs), so there is the possibility of the zoonotic or cross-species transmission of AdVs. As with humans, AdV infections in animals can cause diseases that range from asymptomatic to fatal.

Effect of a Normal-State Pseudogap on Optical Conductivity in Underdoped Cuprate Superconductors

open access: yes, 1999
We calculate the c-axis infrared conductivity $\sigma_c(\omega)$ in underdoped cuprate superconductors for spinfluctuation exchange scattering within the CuO$_2$-planes including a phenomenological d-wave pseudogap of amplitude $E_g$.

High-Transmission-Efficiency 120 $^{\circ}$ Photonic Crystal Waveguide Bend by Using Flexible Structural Defects

open access: yesIEEE Photonics Journal, 2014
We numerically studied a high-output-transmission-efficiency low-reflection-loss 120° photonic crystal (PhC) waveguide bend based on a PhC slab with triangular-lattice air holes.
