Complementarity-based nonlinear programming techniques for optimal mixing in gas networks

open access: yesEURO Journal on Computational Optimization, 2019
We consider nonlinear and nonsmooth mixing aspects in gas transport optimization problems. As mixed-integer reformulations of pooling-type mixing models already render small-size instances computationally intractable, we investigate the applicability of ...

Synthesis, Structural Characterization, and Biological Activity of New Pyrazolo[4,3-e][1,2,4]triazine Acyclonucleosides

open access: yesMolecules, 2020
A series of new pyrazolo[4,3-e][1,2,4]triazine acyclonucleosides 2−5 and 8 were prepared and evaluated for their anticancer activity against human cancer cell lines (MCF-7, K-562) and CDK2/E, as well as Abl protein kinases inhibitors. Lipophilicity

New Estimates On Various Critical/Universal Quantities of the 3D Ising Model [PDF]

open access: yes, 1997
We present estimates for the 3D Ising model on the cubic lattice, both regarding interface and bulk properties. We have results for the interface tension, in particular the amplitude sigma0 in the critical law sigma = sigma0*t**mu, and for the universal ...

A complete search method for the relaxed traveling tournament problem

open access: yesEURO Journal on Computational Optimization, 2014
The traveling tournament problem is a sports scheduling problem that includes two major issues in creating timetables: home/away pattern feasibility and travel distance.

The development of emotion recognition from facial expressions and non-linguistic vocalizations during childhood [PDF]

open access: yes, 2014
Sensitivity to facial and vocal emotion is fundamental to children's social competence. Previous research has focused on children's facial emotion recognition, and few studies have investigated non-linguistic vocal emotion processing in childhood.

Matheuristics for optimizing the network in German wagonload traffic

open access: yesEURO Journal on Computational Optimization, 2017
In this paper, we consider a capacitated multiple allocation hub location problem derived from a practical application in network design of German wagonload traffic.

Photosynthetic activity and metabolic profiling of bread wheat cultivars contrasting in drought tolerance

open access: yesFrontiers in Plant Science, 2023
The rapid increase in population growth under changing climatic conditions causes drought stress, threatening world food security. The identification of physiological and biochemical traits acting as yield-limiting factors in diverse germplasm is pre ...

Quadrupole transitions in the bound rotational-vibrational spectrum of the deuterium molecular ion

open access: yes, 2013
After the study of the three body molecular system H$_2^+$ ({\it J. Phys. B: At. Mol. Opt. Phys.} {\bf 45} 065101), its isotopomer, the deuterium molecular ion D$_2^+$ is studied.

Improving the Quark Number Susceptibilities for Staggered Fermions [PDF]

open access: yes, 2002
Quark number susceptibilities approach their ideal gas limit at sufficiently high temperatures. As in the case of other thermodynamic quantities, this limit itself is altered substantially on lattices with small temporal extent, N_t = 4-8, making it thus

Evaluating performance of image segmentation criteria and techniques

open access: yesEURO Journal on Computational Optimization, 2013
The image segmentation problem is to delineate, or segment, a salient feature in an image. As such, this is a bipartition problem with the goal of separating the foreground from the background. An NP-hard optimization problem, the Normalized Cut problem,
