Characterization of Wolbachia enhancing domain in mosquitoes with imperfect maternal transmission

open access: yesJournal of Biological Dynamics, 2018
A novel method to reduce the burden of dengue is to seed wild mosquitoes with Wolbachia-infected mosquitoes in dengue-endemic areas. Concerns in current mathematical models are to locate the Wolbachia introduction threshold.

Quantifying the survival uncertainty of Wolbachia-infected mosquitoes in a spatial model

open access: yesMathematical Biosciences and Engineering, 2018
Artificial releases of Wolbachia-infected Aedes mosquitoes have been under study in the past yearsfor fighting vector-borne diseases such as dengue, chikungunya and zika.Several strains of this bacterium cause cytoplasmic incompatibility (CI) and can ...

Modeling of Replacement Alternatives for Power Transformer Populations [PDF]

open access: yesIEEE Transactions on Power Delivery, 2012
The age of the majority of power transformers installed in the western electricity network reaches 30 to 60 years and replacement on short term seems eminent. A technically sound policy concerning the replacement of these assets requires a model that estimates the life expectancies of individual components and from that calculates parameters related to

The time to decline: tracing a cohort’s descendants in below replacement populations

open access: yesGenus, 2018
A number of contemporary populations are exhibiting sustained fertility at levels substantially below long-term replacement. Nonetheless, relatively few populations are actually diminishing in size.

Immigration and the prospects for long-run population decreases in European countries

open access: yesVienna Yearbook of Population Research, 2023
Between 2009 and 2018, the total fertility rate fell in most European countries. In 2018, fertility was below the replacement level throughout Europe. Net migration was positive for two-thirds of European countries.

Concentration inequalities for sampling without replacement [PDF]

open access: yes, 2015
Concentration inequalities quantify the deviation of a random variable from a fixed value. In spite of numerous applications, such as opinion surveys or ecological counting procedures, few concentration results are known for the setting of sampling ...

Association between urinary sodium, creatinine, albumin, and long term survival in chronic kidney disease [PDF]

open access: yes, 2014
Dietary sodium intake is associated with hypertension and cardiovascular risk in the general population. In patients with chronic kidney disease, sodium intake has been associated with progressive renal disease, but not independently of proteinuria.
