Enhanced compact models for the connected subgraph problem and for the shortest path problem in digraphs with negative cycles
(2013 , Article)
We investigate the minimum-weight connected subgraph problem. The importance of this problem stems from the fact that it constitutes the backbone of many network design problems having applications in several areas including ...
Improved bounds for hybrid flow shop scheduling with multiprocessor tasks
(2013 , Article)
In this paper, we investigate the problem of minimizing makespan in a multistage hybrid flow-shop scheduling with multiprocessor tasks. To generate high-quality approximate solutions to this challenging NP-hard problem, ...
A branch-and-price algorithm for the two-stage guillotine cutting stock problem
(
Palgrave Macmillan Ltd.
, 2013 , Article)
We investigate the two-stage guillotine two-dimensional cutting stock problem. This problem commonly arises in the industry when small rectangular items need to be cut out of large stock sheets. We propose an integer ...
A lifted compact formulation for the daily aircraft maintenance routing problem
(
INFORMS Inst.for Operations Res.and the Management Sciences
, 2013 , Article)
Given a set of flights for a specific fleet type the aircraft routing problem (ARP) determines the flying sequence for each individual aircraft while incorporating specific considerations of minimum turn time maintenance ...
Addressing security compatibility for multi-tenant cloud services
(
Inderscience Publishers
, 2013 , Article)
This paper addresses the issue of compatibility checking between the security requirements of service clients and the security assurances provided by multi-tenant cloud services. To allow early detection of security ...
A solid-phase extractant based on microemulsion modified date pits for toxic pollutants
(
Elsevier
, 2013 , Article)
Application of microemulsion modified raw date pits as an inexpensive solid extractant for removing methylene blue (MB), copper ion (Cu2+) and cadmium ion (Cd2+) has been presented. The results summarised herein are also ...
Natural and depleted uranium in the topsoil of Qatar: Is it something to worry about?
(
Elsevier
, 2013 , Article)
This study examines uranium in soils of Qatar to investigate whether there is any detectable traces of depleted uranium (DU). 409 soil samples were collected using a 10km grid system throughout the State of Qatar. The U ...
The effect of moderate and high-intensity fatigue on groundstroke accuracy in expert and non-expert tennis players
(
PMC
, 2013 , Article)
Exploring the effects of fatigue on skilled performance in tennis presents a significant challenge to the researcher with respect to ecological validity. This study examined the effects of moderate and high-intensity fatigue ...
A new hybrid extragradient iterative method for approximating the common solutions of a system of variational inequalities, a mixed equilibrium problem, and a hierarchical fixed point problem
(
Hindawi
, 2013 , Article)
We suggest and analyze an iterative scheme for finding the approximate element of the common set of solutions of a system of variational inequalities, a mixed equilibrium problem, and a hierarchical fixed point problem in ...
Salinomycin induces apoptosis and senescence in breast cancer: Upregulation of p21, downregulation of survivin and histone H3 and H4 hyperacetylation
(
Elsevier
, 2013 , Article)
Background
In the present study, we investigated the effect of Salinomycin on the survival of three human breast cancer cell lines MCF-7, T47D and MDA-MB-231 grown in adherent culture conditions.
Methods
