text: The free exciton transition (near-band-edge emission, NBE) of ZnO at ≈388
nm can be strongly enhanced and even stimulated by an underlying photonic structure.
1D Photonic crystals, so-called distributed Bragg reflectors, are utilized to
suppress the deep-level emission of ZnO (DLE, ≈500–530 nm). The reflector stacks
are fabricated in a layer-by-layer procedure by wet-chemical synthesis. They consist
of low-ε porous SiO2 layers and high-ε TiO2 layers. Varying the thickness of the
SiO2 layers allows tuning the optical bandgap in a wide range between ≈420 and
800 nm. A ZnO layer is deposited on top of the reflector stacks by sol–gel synthesis.
The spontaneous photoluminescence (PL) emission of the ZnO film is modulated by
the photonic structure. When the optical bandgap of the reflector is in resonance
with the deep-level emission of ZnO (DLE, ≈500–530 nm), then this defect-related
emission mode is suppressed. Strong NBE emission is observed even when the ZnO
layer does not show any NBE emission (due to low crystallinity) in the absence
of the photonic structure. With this cost-efficient synthesis method, emitters
for, e.g., luminescent gas sensors can be fabricated.

text: "\r\nDestructive micrograph analysis (MA) is the standard method for
the assessment of clinched joints. However, during the joint preparation for the
MA, geometric features of the joint can change due to elastic effects and closing
cracks. X-ray computed tomography (CT) is a promising alternative to investigate
the joint non-estructively. However, if the material properties of similar joining
partners are the same, the CT is not able to correctly resolve surfaces in the
joint that are close to or pressing onto each other. These surfaces are relevant
for the determination of characteristic dimensions such as neck thickness and
undercut. By placing a thin, highly radiopaque tin layer between the joining partners,
the interfacial area in the reconstructed volume can be highlighted. In this work,
a method for the localisation of the tin layer inside the joint as well as threshold
value procedures for the outer joint contour in cross section images are investigated.
The measured characteristic dimensions are compared with measured values from
MA of the same samples and of samples without tin layer. In addition, possible
effects of the tin layer on the joining point characteristics as well as problems
of the MA are discussed.\r\n"

text: Zur Qualitätssicherung von Clinchpunkten werden häufig ex-situ Methoden, wie
etwa Schliffbildanalysen, eingesetzt. Diese ermöglichen jedoch nicht die Berücksichtigung
von Phänomenen, die während der Belastung auftreten, da sich nach der Entlastung
elastische Deformationen zurückbilden und Risse wieder schließen. Dagegen kann
mit der in-situ Computertomographie (CT) der innere Deformationszustand des Clinchpunkts,
z.B. während eines Scherzugversuchs, untersucht werden. Hierbei ist es für artgleiche
Werkstoffe aufgrund der hohen Pressungen im Clinchpunkt schwierig, die Trennfläche
zwischen den Fügepartnern im CT-Scan zu erkennen. Daher wird eine radioopake Zwischenschicht
aus Zinn in die Trennfläche eingebracht. In dieser Arbeit wird der Einfluss der
Zwischenschicht auf die in-situ CT-Scherzugprüfung untersucht. Hierzu werden sowohl
Kraft-Verlängerungs-Kurven als auch die Geometrie der Clinchpunkte während der
Belastung verglichen.

text: Clinching is a cost efficient method for joining components in series
production. To assure the clinch point’s quality, the force displacement curve
during clinching or the bottom thickness are monitored. The most significant geometrical
characteristics of the clinch point, neck thickness and undercut, are usually
tested destructively by microsectioning. However, micrograph preparation goes
ahead with a resetting of elastic deformations and crack-closing after unloading.
To generate a comprehensive knowledge of the clinch point’s inner geometry under
load, in-situ computed tomography (CT) and acoustic testing (TDA) can be combined.
While the TDA is highly sensitive to the inner state of the clinch point, it could
detect critical events like crack development during loading. If such events are
indicated, the loading process is stopped and a stepped in-situ CT of the following
crack and deformation development is performed. In this paper, the concept is
applied to the process of clinching itself, providing a detailed three-dimensional
insight in the development of the joining zone. A test set-up is used which allows
a stepwise clinching of two aluminium sheets EN AW 6014. Furthermore, this set-up
is positioned within a CT system. In order to minimize X-ray absorption, a beryllium
cylinder is used within the set-up frame and clinching tools are made from Si3N4.
The actuator and sensor necessary for the TDA are integrated in the set-up. In
regular process steps, the clinching process is interrupted in order to perform
a TDA and a CT scan. In order to enhance the visibility of the interface, a thin
tin layer is positioned between the sheets prior clinching. It is shown, that
the test-set up allows a monitoring of the dynamic behaviour of the specimen during
clinching while the CT scans visualize the inner geometry and material flow non-destructively.

text: "We review recent results on the existence of ground states for the\r\ninfrared-critical
spin boson model, which describes the interaction of a\r\nmassless bosonic field
with a two-state quantum system. Explicitly, we derive a\r\ncritical coupling
$\\lambda_{\\mathsf c}>0$ such that the spin boson model\r\nexhibits a ground
state for coupling constants $\\lambda$ with\r\n$|\\lambda|<\\lambda_{\\mathsf
c}$. The proof combines a Feynman-Kac-Nelson\r\nformula for the spin boson model
with external magnetic field, a 1D-Ising model\r\ncorrelation bound and a compactness
argument in Fock space. Elaborating on the\r\nconnection to a long-range 1D-Ising
model, we briefly discuss the conjecture\r\nthat the spin boson model does not
have a ground state at large coupling. This\r\nnote is based on joint work with
David Hasler and Oliver Siebert."

text: We consider the spin boson model with external magnetic field. We prove a
path integral formula for the heat kernel, known as Feynman–Kac–Nelson (FKN) formula.
We use this path integral representation to express the ground state energy as
a stochastic integral. Based on this connection, we determine the expansion coefficients
of the ground state energy with respect to the magnetic field strength and express
them in terms of correlation functions of a continuous Ising model. From a recently
proven correlation inequality, we can then deduce that the second order derivative
is finite. As an application, we show existence of ground states in infrared-singular
situations.
