The Neumann problem for (0.1)$$ \begin{align}& V_t = \Delta V-aV+f(x,t) \end{align}$$is considered in bounded domains $\Omega \subset {\mathbb {R}}^n$ with smooth boundary, where $n\ge 1$ and $a\in {\mathbb {R}}$. By means of a variational approach, a statement on boundedness of the quantities $$ \begin{eqnarray*} \sup_{t\in (0,T)} \int_\Omega \big|\nabla V(\cdot,t)\big|^p L^{\frac{n+p}{n+2}} \Big( \big|\nabla V(\cdot,t)\big| \Big) \end{eqnarray*}$$in dependence on the expressions (0.2)$$ \begin{align}& \sup_{t\in (0,T-\tau)} \int_t^{t+\tau} \int_\Omega |f|^{\frac{(n+2)p}{n+p}} L\big( |f|\big) \end{align}$$is derived for $p\ge 2$, $\tau>0$, and $T\ge 2\tau $, provided that $L\in C^0([0,\infty ))$ is positive, strictly increasing, unbounded, and slowly growing in the sense that $\limsup _{s\to \infty } \frac {L(s^{\lambda _0})}{L(s)} <\infty $ for some $\lambda _0>1$. In the particular case when $p=n\ge 2$, an additional condition on growth of $L$, particularly satisfied by $L(\xi ):=\ln ^\alpha (\xi +b)$ whenever $b>0$ and $\alpha>\frac {(n+2)(n-1)}{2n}$, is identified as sufficient to ensure that as a consequence of the above, bounds for theintegrals in (0.2) even imply estimates for the spatio-temporal modulus of continuity of solutions to (0.1). A subsequent application to the Keller–Segel system $$ \begin{eqnarray*} \left\{ \begin{array}{l} u_t = \nabla \cdot \big( D(v)\nabla u\big) - \nabla \cdot \big( uS(v)\nabla v\big) + ru - \mu u^2, \\[1mm] v_t = \Delta v-v+u, \end{array} \right. \end{eqnarray*}$$shows that when $n=2$, $r\in {\mathbb {R}}$, $0<D\in C^2([0,\infty ))$, and $S\in C^2([0,\infty )) \cap W^{1,\infty }((0,\infty ))$ and thus especially in the presence of arbitrarily strong diffusion degeneracies implied by rapid decay of $D$, any choice of $\mu>0$ excludes blowup in the sense that for all suitably regular nonnegative initial data, an associated initial-boundary value problem admits a global bounded classical solution.}},

As pop music cultures, in their entire breadth, can be described as seismographs of social, political, economic, ecological, media, artistic, and technological transformations, in and through them, fields of tensions, disruptions, and lines of conflict become not only visible, audible, and perceptible, but also communicable and thus, negotiable. Volume No. 2 of ~Vibes – The IASPM D-A-CH Series, which is based on the 4th Biennial IASPM D-A-CH conference at Paderborn University/online, takes a closer look at the transformative moments of pop music cultures by theorizing, empiricizing, historicizing, and, finally, politicizing them.}},

abstract = {{Classifying nodes in knowledge graphs is an important task, e.g., predicting
missing types of entities, predicting which molecules cause cancer, or
predicting which drugs are promising treatment candidates. While black-box
models often achieve high predictive performance, they are only post-hoc and
locally explainable and do not allow the learned model to be easily enriched
with domain knowledge. Towards this end, learning description logic concepts
from positive and negative examples has been proposed. However, learning such
concepts often takes a long time and state-of-the-art approaches provide
limited support for literal data values, although they are crucial for many
applications. In this paper, we propose EvoLearner - an evolutionary approach
to learn ALCQ(D), which is the attributive language with complement (ALC)
paired with qualified cardinality restrictions (Q) and data properties (D). We
contribute a novel initialization method for the initial population: starting
from positive examples (nodes in the knowledge graph), we perform biased random
walks and translate them to description logic concepts. Moreover, we improve
support for data properties by maximizing information gain when deciding where
to split the data. We show that our approach significantly outperforms the
state of the art on the benchmarking framework SML-Bench for structured machine
learning. Our ablation study confirms that this is due to our novel
initialization method and support for data properties.}},
