text: Complexity of products and systems is increasing through digitalization, interdisciplinarity
as well as high technology maturity and new business models. In consequence, new
product development (NPD) projects need to manage and satisfy a large number of
requirements from a broad range of stakeholders. Yet, NPD projects are often delayed
due to requirement changes. In this paper, a new method for analyzing requirement
change propagation is presented. The method is based on the assessment of requirement
interrelations structured in a requirements structure matrix by a modified page-rank
algorithm. By the method, a high number of strongly interrelated requirements
can be analyzed in an efficient manner. Additionally, higher-level interrelations
as well as the relative weights of requirements are also incorporated in the analysis.
Hereby, an efficient holistic approach towards the analysis of requirement change
propagation is proposed.

text: The combined benefits of moisture-stable phosphonic acids and mesoporous
silica materials (SBA-15 and MCM-41) as large-surface-area solid supports offer
new opportunities for several applications, such as catalysis or drug delivery.
We present a comprehensive study of a straightforward synthesis method via direct
immobilization of several phosphonic acids and phosphoric acid esters on various
mesoporous silicas in a Dean–Stark apparatus with toluene as the solvent. Due
to the utilization of azeotropic distillation, there was no need to dry phosphonic
acids, phosphoric acid esters, solvents, or silicas prior to synthesis. In addition
to modeling phosphonic acids, immobilization of the important biomolecule adenosine
monophosphate (AMP) on the porous supports was also investigated. Due to the high
surface area of the mesoporous silicas, a possible catalytic application based
on immobilization of an organocatalyst for an asymmetric aldol reaction is discussed.

text: ' The potential for biases being built into algorithms has been known
for some time (e.g., Friedman and Nissenbaum, 1996), yet literature has only recently
demonstrated the ways algorithmic profiling can result in social sorting and harm
marginalised groups (e.g., Browne, 2015; Eubanks, 2018; Noble, 2018). We contend
that with increased algorithmic complexity, biases will become more sophisticated
and difficult to identify, control for, or contest. Our argument has four steps:
first, we show how harnessing algorithms means that data gathered at a particular
place and time relating to specific persons, can be used to build group models
applied in different contexts to different persons. Thus, privacy and data protection
rights, with their focus on individuals (Coll, 2014; Parsons, 2015), do not protect
from the discriminatory potential of algorithmic profiling. Second, we explore
the idea that anti-discrimination regulation may be more promising, but acknowledge
limitations. Third, we argue that in order to harness anti-discrimination regulation,
it needs to confront emergent forms of discrimination or risk creating new invisibilities,
including invisibility from existing safeguards. Finally, we outline suggestions
to address emergent forms of discrimination and exclusionary invisibilities via
intersectional and post-colonial analysis. '

text: A nanocomposite material based on copper(II) oxide (CuO) and its utilization
as a highly selective and stable gas-responsive electrical switch for hydrogen
sulphide (H2S) detection is presented. The material can be applied as a sensitive
layer for H2S monitoring, e.g., in biogas gas plants. CuO nanoparticles are embedded
in a rigid, nanoporous silica (SiO2) matrix to form an electrical percolating
network of low conducting CuO and, upon exposure to H2S, highly conducting copper(II)
sulphide (CuS) particles. By steric hindrance due to the silica pore walls, the
structure of the network is maintained even though the reversible reaction of
CuO to CuS is accompanied by significant volume expansion. The conducting state
of the percolating network can be controlled by a variety of parameters, such
as temperature, electrode layout, and network topology of the porous silica matrix.
The latter means that this new type of sensing material has a structure-encoded
detection limit for H2S, which offers new application opportunities. The fabrication
process of the mesoporous CuO@SiO2 composite as well as the sensor design and
characteristics are described in detail. In addition, theoretical modeling of
the percolation effect by Monte-Carlo simulations yields deeper insight into the
underlying percolation mechanism and the observed response characteristics.

text: The cubic, tetragonal, and orthorhombic phase of potassium niobate (KNbO3)
are studied based on density-functional theory. Starting from the relaxed atomic
geometries, we analyze the influence of self-energy corrections on the electronic
band structure within the GW approximation. We find that quasiparticle shifts
widen the direct (indirect) band gap by 1.21 (1.44), 1.58 (1.55), and 1.67 (1.64)
eV for the cubic, tetragonal, and orthorhombic phase, respectively. By solving
the Bethe-Salpeter equation, we obtain the linear dielectric function with excitonic
and local-field effects, which turn out to be essential for good agreement with
experimental data. From our results, we extract an exciton binding energy of 0.6,
0.5, and 0.5 eV for the cubic, tetragonal, and orthorhombic phase, respectively.
Furthermore, we investigate the nonlinear second-harmonic generation (SHG) both
theoretically and experimentally. The frequency-dependent second-order polarization
tensor of orthorhombic KNbO3 is measured for incoming photon energies between
1.2 and 1.6 eV. In addition, calculations within the independent-(quasi)particle
approximation are performed for the tetragonal and orthorhombic phase. The novel
experimental data are in excellent agreement with the quasiparticle calculations
and resolve persistent discrepancies between earlier experimental measurements
and ab initio results reported in the literature.

text: 'The KTiOPO4 (KTP) band structure and dielectric function are calculated on
various levels of theory starting from density-functional calculations. Within
the independent-particle approximation an electronic transport gap of 2.97 eV
is obtained that widens to about 5.23 eV when quasiparticle effects are included
using the GW approximation. The optical response is shown to be strongly anisotropic
due to (i) the slight asymmetry of the TiO6 octahedra in the (001) plane and (ii)
their anisotropic distribution along the [001] and [100] directions. In addition,
excitonic effects are very important: The solution of the Bethe–Salpeter equation
indicates exciton binding energies of the order of 1.5 eV. Calculations that include
both quasiparticle and excitonic effects are in good agreement with the measured
reflectivity.'
