Probabilistic Analysis of Facility Location on Random Shortest Path Metrics [PDF]

, 2019
The facility location problem is an NP-hard optimization problem. Therefore, approximation algorithms are often used to solve large instances. Such algorithms often perform much better than worst-case analysis suggests.

Three-year trends in malaria transmission parameters under deployment of Interceptor®G1, Interceptor®G2 and PermaNet®3.0 insecticide-treated bed nets in South-Western Burkina Faso

Malaria Journal
Background In South-Western Burkina Faso, where malaria remains highly endemic, the widespread resistance of Anopheles mosquitoes to pyrethroid is reducing the effectiveness of insecticide-treated nets (ITNs).

Differential effects of dual and synergist-based insecticide-treated bed nets on pyrethroid resistance and L995F/S knockdown resistance mutation dynamics in Anopheles gambiae s.l. populations in south-western Burkina Faso

Parasites & Vectors
Background The introduction of next-generation insecticide-treated nets (ITNs) in Burkina Faso aims to mitigate pyrethroid resistance in malaria vectors.

Antenatal care surveillance for monitoring malaria prevalence and intervention coverage: a multicountry analysis

BMJ Global Health
Estimates of malaria prevalence and intervention coverage in Africa are primarily based on nationally representative household (HH) surveys. However, the expense and infrequency limit the utility of HH surveys for operational action by malaria programmes.

Can food security and low carbon be achieved simultaneously? —An empirical analysis of the mechanisms influencing the carbon footprint of potato and corn cultivation in irrigation areas

Journal of Integrative Agriculture, 2023
Irrigated agriculture has tripled since 1950, accounting for 20% of the global arable land and 40% of food production. Irrigated agriculture increases food security yet has controversial implications for global climate change.

Generalized Shortest Path Kernel on Graphs

, 2015
We consider the problem of classifying graphs using graph kernels. We define a new graph kernel, called the generalized shortest path kernel, based on the number and length of shortest paths between nodes.

The stepwise path integral of the relativistic point particle

, 2018
In this paper we present a stepwise construction of the path integral over relativistic orbits in Euclidean spacetime. It is shown that the apparent problems of this path integral, like the breakdown of the naive Chapman-Kolmogorov relation, can be ...

Exploring the epidemiological impact of attractive targeted sugar bait against malaria in combination with standard malaria control

Current Research in Parasitology and Vector-Borne Diseases
Attractive targeted sugar bait (ATSB) is a potential new vector control tool that exploits the sugar-feeding behaviour of mosquitoes. Little is known about the factors which drive ATSB efficacy, either as a standalone vector control tool or in ...
