Subject: MFEM Version 4.3


Version 4.3 of MFEM, a lightweight, general, scalable C++ library for
finite element methods, is now available at: https://mfem.org

The goal of MFEM is to enable high-performance scalable finite element
discretization research and application development on a wide variety
of platforms, ranging from laptops to exascale supercomputers.

Some of the new additions in version 4.3 are:
- Variable order spaces, serial p- and hp-refinement.
- Low order refined discretizations, solvers and transfer.
- Preconditioners for advection-dominated systems.
- Support for GPU solvers from hypre and PETSc.
- GPU-accelerated mesh optimization algorithms.
- Explicit vectorization for Fujitsu's A64FX ARM microprocessor.
- Support for high-order Lagrange meshes in VTK format.
- New and improved integrations with FMS, Caliper, libCEED, Ginkgo.
- 18 new examples and miniapps.

The MFEM library has many more features, including:
- 2D and 3D, arbitrary order H1, H(curl), H(div), L2, NURBS elements.
- Parallel version scalable to hundreds of thousands of MPI cores.
- Conforming/nonconforming adaptive mesh refinement (AMR), including
anisotropic refinement, derefinement and parallel load balancing.
- Galerkin, mixed, isogeometric, discontinuous Galerkin, hybridized,
and DPG discretizations.
- Support for triangular, quadrilateral, tetrahedral and hexahedral
elements, including arbitrary order curvilinear meshes.
- Scalable algebraic multigrid, time integrators, and eigensolvers.
- Lightweight interactive OpenGL visualization with the MFEM-based
GLVis tool.

Date: July 21, 2021 ; ISBN: 978-620-2-80240-6
Language: English; Pages number: 488 ; Price: 98.90 Euro

In this monograph, recent years published papers on the quantum
control had been collected both for theoretical study and numerical
approach. The practical application to the quantum systems covered the
Klein-Gordon equation; Sine-Gordon equation; Klein-Gordon-Schrodinger
equation (KGS); Gross-Pitaevaskii equation (Bose-Einstein Condensates,
BEC); Klein-Gordon-Maxwell equation, and so forth. For the particles
physics, single particle, couple heavy particles, many body particles
problems had been considered in the quantum theory and computational
approach. Three parts contained in the book, Part I is Quantum
Control of KGS System; Part II is Quantum Control of BEC; Part III is
Control of Quantum System. It is certainly hope to connect system
control field to chemistry, physics as well as other research areas
(aero space, surface science, etc.). Thereby, wish to get much more
interest worldwide on the hot topic quantum system control.

Subject: PhD Position, Univ Sorbonne Paris Nord, France


One PhD position is opened at Universite Sorbonne Paris Nord, France
(these CIFRE). The position is in collaboration with Horizontal
Sofware (https://www.horizontalsoftware.com/).

Horizontal Software (HSW), created in 2010, is a publisher of SaaS and
App solutions, specialized in management and optimized planning of
human resources. The E-OPTIM solution provided by HSW is intended for
the planning and optimization of human resources, taking into account
heterogeneous constraints: legal, organizational and social. A
company's performance is closely linked to well-being at work. It is
therefore very important to take into account employee preferences in
the development of schedules. The goal of the PhD thesis is to develop
heuristic algorithms that take into account employee preferences in
addition to the standard constraints (legal, organizational and
social). This additional requirement poses a severe challenge as it
complicates a problem that is already difficult to solve. To overcome
this challenge the candidate will use the most advanced techniques in
the field of mathematical optimization and artificial intelligence.

Required competences: Good experience with mathematical optimization;
Knowledge in machine learning and deep learning is considered as a
plus; Excellent programming skills.

To apply or to have more information, please contact Roberto Wolfler
Calvo (wolfler@lipn.univ-paris13.fr) and Nora Touati
