Mixed‐Integer Linear Programming Approaches for Nested p$$ p $$‐Center Problems With Absolute and Relative Regret Objectives

open access: yesNetworks, EarlyView.
ABSTRACT We introduce the nested p$$ p $$‐center problem, a multi‐period variant of the well‐known p$$ p $$‐center problem. Using the nesting concept allows us to obtain solutions consistent over the considered time horizon, that is, facilities that are opened in a given time period stay open for subsequent periods.

Planet formation in post-common-envelope binaries

open access: yes, 2015
To understand the evolution of planetary systems, it is important to investigate planets in highly evolved stellar systems, and to explore the implications of their observed properties with respect to potential formation scenarios.

On the Habitable Zones of Circumbinary Planetary Systems [PDF]

open access: yes, 2012
The effect of the stellar flux on exoplanetary systems is becoming an increasingly important property as more planets are discovered in the habitable zone (HZ).

Comprehensive Surrogate Models for Predicting the Melt Conveying Characteristics of Channel Segments in High‐Performance Single‐Screw Extruders

open access: yesPolymer Engineering &Science, EarlyView.
Generalized analytical equations were developed that accurately predict the local pumping characteristics, viscous dissipation, and average shear rates in channels of both conventional and high‐performance single‐screw extruders. Applied within segmented extruder calculations, these models aid in screw design and process troubleshooting without the ...

Introducing Critical Systems Heuristics 2.0: A Third Boundary Extending CSH From Reflections on Critical Realism in Information Systems Research

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Poorly designed information systems compel employees to find workarounds for the system in order to do their work properly. However, such workarounds compromise the enforcement of organisational governance. In our sense‐making of this specific phenomenon, we considered critical realism as a framework for understanding based on its adoption in ...

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

open access: yessteel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

The scattering outcomes of Kepler circumbinary planets: planet mass ratio

open access: yes, 2017
Recent studies reveal that the free eccentricities of Kepler-34b and Kepler-413b are much larger than their forced eccentricities, implying that the scattering events may take place in their formation.

Anterior Segment Optical Coherence Tomography and Anterior Segment Optical Coherence Tomography Angiography After Bleb Forming Glaucoma Surgeries: A Systematic Review

open access: yesClinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background The bleb‐forming surgical spectrum in open‐angle glaucoma has recently been expanded by novel surgical approaches. Through a medical device implantation (Xen Gel Stent (XGI) or Preserflo Microshunt (PMI)), these procedures aim at more standardised aqueous humour shunting and an intra‐ and postoperative risk reduction ...

The quest for companions to post-common envelope binaries IV: The 2:1 mean-motion resonance of the planets orbiting NN Serpentis

open access: yes, 2013
We present 69 new mid-eclipse times of the young post-common envelope binary (PCEB) NN Ser, which was previously suggested to possess two circumbinary planets.

Heart matters: How glucose‐ and lipid‐modulating drugs remodel epicardial adipose tissue accumulation, inflammatory patterns and browning

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
Abstract Epicardial adipose tissue (EAT) is a metabolically active visceral fat depot located between the myocardium and the visceral pericardium, exerting direct paracrine and vasocrine effects on the heart and coronary vessels. Under physiological conditions, EAT supports myocardial energy metabolism and thermoregulation through fatty acid supply and
