An Improved Tabu Search Algorithm for the Stochastic Vehicle Routing Problem With Soft Time Windows

open access: yesIEEE Access, 2020
In real-world environments, vehicle travel and service time will be affected by unpredictable factors and present a random state. Because of this situation, this article proposes the vehicle routing problem with soft time windows and stochastic travel ...

Modelling the Impact of Transport Planning Policy Upon Land Use [PDF]

open access: yes, 1979
In this paper the results from the validation of an integrated land use and transport model are described. The goodness-of-fit for the forecasts are considered not only for the time horizon, but also in terms of the change over time, which is a much more

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Selfishness and Altruism in the Distribution of Travel Time and Income [PDF]

open access: yes
Most economic models assume that individuals act out their preferences based on their own self interest. However there have also been other paradigms in the economics literature that have tried to capture alternative manifestations of human behavior that

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Travel Time Reliability for Urban Networks: Modelling and Empirics

open access: yesJournal of Advanced Transportation, 2017
The importance of travel time reliability in traffic management, control, and network design has received a lot of attention in the past decade. In this paper, a network travel time distribution model based on the Johnson curve system is proposed.

Defining travel-associated cases of enteric fever

open access: yesJournal of Infection and Public Health, 2014
Summary: There is no internationally recognized case-definition for travel-associated enteric fever in non-endemic countries. This study describes the patterns of case reporting between 2007 and 2011 as travel-associated or not from the surveillance data
