text: AbstractSemiconductor quantum dots are excellent
candidates for ultrafast coherent manipulation of qubits by laser pulses on picosecond
timescales or even faster. In inhomogeneous ensembles a macroscopic optical polarization
decays rapidly due to dephasing, which, however, is reversible in photon echoes
carrying complete information about the coherent ensemble dynamics. Control of
the echo emission time is mandatory for applications. Here, we propose a concept
to reach this goal. In a two-pulse photon echo sequence, we apply an additional
resonant control pulse with multiple of 2π area. Depending
on its arrival time, the control slows down dephasing or rephasing of the exciton
ensemble during its action. We demonstrate for self-assembled (In,Ga)As quantum
dots that the photon echo emission time can be retarded or advanced by up to 5
ps relative to its nominal appearance time without control. This versatile protocol
may be used to obtain significantly longer temporal shifts for suitably tailored
control pulses.

text: Vortices are topological objects representing the circular motion of a fluid.
With their additional degree of freedom, the vorticity, they have been widely
investigated in many physical systems and different materials for fundamental
interest and for applications in data storage and information processing. Vortices
have also been observed in non-equilibrium exciton-polariton condensates in planar
semiconductor microcavities. There they appear spontaneously or can be created
and pinned in space using ring-shaped optical excitation profiles. However, using
the vortex state for information processing not only requires creation of a vortex
but also efficient control over the vortex after its creation. Here we demonstrate
a simple approach to control and switch a localized polariton vortex between opposite
states. In our scheme, both the optical control of vorticity and its detection
through the orbital angular momentum of the emitted light are implemented in a
robust and practical manner.

text: The influence of latent heat storage elements on the cooling performance and
the temperature rise time of household refrigerating appliances is studied experimentally
in the context of the “new global refriger- ator standard”IEC 62552:2015. In addition
to the daily energy consumption, this international standard- ization introduced
performance tests for cooling capacity and temperature rise time. While the cooling
capacity has long been anchored in various test procedures of consumer organizations,
the temperature rise time, which has only been tested on freezers so far, will
be a decisive factor in the future. Moreover, the need for so-called "smart appliances"
that may balance power consumption is increasing since such devices may compensate
the volatility of renewable energies and thus stabilize the power grid. Against
this background, eight commercial household refrigerators and refrigerator-freezers
are equipped with polymer-bound phase change materials (PCM) and their performance
is determined under the new stan- dard test conditions. The results show that
the introduction of PCM increases the cooling capacity by up to 33 % and also
increases the temperature rise time by up to 145 %, without affecting power consump-
tion, as compared to the unmodified refrigeration appliances.

text: This paper presents the results of static short-term and long-term tensile
tests for beta-nucleated joined polypropylene samples by the hot plate welding
process. In the present study different dimensionless joining displacements are
accounted for. The results show that high short-term tensile strength does not
directly transfer to high long-term tensile strength. The morphology of the weld
seam in the joined samples is examined by means of transmitted and reflected light
microscopy. For the dimensionless joining displacements of 0.75 and 0.95, stretched
spherulites are obtained. X-Ray diffraction can be used as a tool for qualitative
and quantitative analysis and eventually for differentiation of samples of various
joining displacements.

text: "Abstract\r\nSafety-relevant components in
automobiles require materials that combine high strength with sufficient residual
ductility and high-energy absorption. A graded thermo-mechanical treatment of
the press-hardening steel 22MnB5 with graded microstructure can provide a material
with such properties. Different austenitization temperatures, cooling and forming
conditions within a sheet part lead to the development of microstructures with
mixed phase compositions. To determine the resulting phase contents in such graded
processed parts, a large number of dilatometric tests are usually required. With
a non-contact characterization method, it is possible to detect local phase transformations
on an inhomogeneously treated flat steel specimen. For press-hardening steel after
heat treatment and thermo-mechanical processing, correlations between austenitization
temperature, hot deformation strain, microstructure, and hardness are established."

text: CP2K is an open source electronic structure and molecular dynamics software
package to perform atomistic simulations of solid-state, liquid, molecular, and
biological systems. It is especially aimed at massively parallel and linear-scaling
electronic structure methods and state-of-theart ab initio molecular dynamics
simulations. Excellent performance for electronic structure calculations is achieved
using novel algorithms implemented for modern high-performance computing systems.
This review revisits the main capabilities of CP2K to perform efficient and accurate
electronic structure simulations. The emphasis is put on density functional theory
and multiple post–Hartree–Fock methods using the Gaussian and plane wave approach
and its augmented all-electron extension.

text: "Electronic structure calculations based on density-functional theory (DFT)\r\nrepresent
a significant part of today's HPC workloads and pose high demands on\r\nhigh-performance
computing resources. To perform these quantum-mechanical DFT\r\ncalculations on
complex large-scale systems, so-called linear scaling methods\r\ninstead of conventional
cubic scaling methods are required. In this work, we\r\ntake up the idea of the
submatrix method and apply it to the DFT computations\r\nin the software package
CP2K. For that purpose, we transform the underlying\r\nnumeric operations on distributed,
large, sparse matrices into computations on\r\nlocal, much smaller and nearly
dense matrices. This allows us to exploit the\r\nfull floating-point performance
of modern CPUs and to make use of dedicated\r\naccelerator hardware, where performance
has been limited by memory bandwidth\r\nbefore. We demonstrate both functionality
and performance of our implementation\r\nand show how it can be accelerated with
GPUs and FPGAs."

text: FPGAs have found increasing adoption in data center applications since a new
generation of high-level tools have become available which noticeably reduce development
time for FPGA accelerators and still provide high-quality results. There is, however,
no high-level benchmark suite available, which specifically enables a comparison
of FPGA architectures, programming tools, and libraries for HPC applications.
To fill this gap, we have developed an OpenCL-based open-source implementation
of the HPCC benchmark suite for Xilinx and Intel FPGAs. This benchmark can serve
to analyze the current capabilities of FPGA devices, cards, and development tool
flows, track progress over time, and point out specific difficulties for FPGA
acceleration in the HPC domain. Additionally, the benchmark documents proven performance
optimization patterns. We will continue optimizing and porting the benchmark for
new generations of FPGAs and design tools and encourage active participation to
create a valuable tool for the community. To fill this gap, we have developed
