text: In this paper we introduce a pruning of the medial axis called the (λ,α)-medial
axis (axλα). We prove that the (λ,α)-medial axis of a set K is stable in a Gromov-Hausdorff
sense under weak assumptions. More formally we prove that if K and K′ are close
in the Hausdorff (dH) sense then the (λ,α)-medial axes of K and K′ are close as
metric spaces, that is the Gromov-Hausdorff distance (dGH) between the two is
1/4-Hölder in the sense that dGH (axλα(K),axλα(K′)) ≲ dH(K,K′)1/4. The Hausdorff
distance between the two medial axes is also bounded, by dH (axλα(K),λα(K′)) ≲
dH(K,K′)1/2. These quantified stability results provide guarantees for practical
computations of medial axes from approximations. Moreover, they provide key ingredients
for studying the computability of the medial axis in the context of computable
analysis.

text: Targeting dysregulated Ca2+ signaling in cancer cells is an emerging chemotherapy
approach. We previously reported that store-operated Ca2+ entry (SOCE) blockers,
such as RP4010, are promising antitumor drugs for esophageal cancer. As a tyrosine
kinase inhibitor (TKI), afatinib received FDA approval to be used in targeted
therapy for patients with EGFR mutation-positive cancers. While preclinical studies
and clinical trials have shown that afatinib has benefits for esophageal cancer
patients, it is not known whether a combination of afatinib and RP4010 could achieve
better anticancer effects. Since TKI can alter intracellular Ca2+ dynamics through
EGFR/phospholipase C-γ pathway, in this study, we evaluated the inhibitory effect
of afatinib and RP4010 on intracellular Ca2+ oscillations in KYSE-150, a human
esophageal squamous cell carcinoma cell line, using both experimental and mathematical
simulations. Our mathematical simulation of Ca2+ oscillations could fit well with
experimental data responding to afatinib or RP4010, both separately or in combination.
Guided by simulation, we were able to identify a proper ratio of afatinib and
RP4010 for combined treatment, and such a combination presented synergistic anticancer-effect
evidence by experimental measurement of intracellular Ca2+ and cell proliferation.
This intracellular Ca2+ dynamic-based mathematical simulation approach could be
useful for a rapid and cost-effective evaluation of combined targeting therapy
drugs.

text: The Voronoi tessellation in Rd is defined by locally minimizing the power
distance to given weighted points. Symmetrically, the Delaunay mosaic can be defined
by locally maximizing the negative power distance to other such points. We prove
that the average of the two piecewise quadratic functions is piecewise linear,
and that all three functions have the same critical points and values. Discretizing
the two piecewise quadratic functions, we get the alpha shapes as sublevel sets
of the discrete function on the Delaunay mosaic, and analogous shapes as superlevel
sets of the discrete function on the Voronoi tessellation. For the same non-critical
value, the corresponding shapes are disjoint, separated by a narrow channel that
contains no critical points but the entire level set of the piecewise linear function.

text: Digital images enable quantitative analysis of material properties at micro
and macro length scales, but choosing an appropriate resolution when acquiring
the image is challenging. A high resolution means longer image acquisition and
larger data requirements for a given sample, but if the resolution is too low,
significant information may be lost. This paper studies the impact of changes
in resolution on persistent homology, a tool from topological data analysis that
provides a signature of structure in an image across all length scales. Given
prior information about a function, the geometry of an object, or its density
distribution at a given resolution, we provide methods to select the coarsest
resolution yielding results within an acceptable tolerance. We present numerical
case studies for an illustrative synthetic example and samples from porous materials
where the theoretical bounds are unknown.

text: The medial axis of a set consists of the points in the ambient space without
a unique closest point on the original set. Since its introduction, the medial
axis has been used extensively in many applications as a method of computing a
topologically equivalent skeleton. Unfortunately, one limiting factor in the use
of the medial axis of a smooth manifold is that it is not necessarily topologically
stable under small perturbations of the manifold. To counter these instabilities
various prunings of the medial axis have been proposed. Here, we examine one type
of pruning, called burning. Because of the good experimental results, it was hoped
that the burning method of simplifying the medial axis would be stable. In this
work we show a simple example that dashes such hopes based on Bing’s house with
two rooms, demonstrating an isotopy of a shape where the medial axis goes from
collapsible to non-collapsible.

text: To compute the persistent homology of a grayscale digital image one needs
to build a simplicial or cubical complex from it. For cubical complexes, the two
commonly used constructions (corresponding to direct and indirect digital adjacencies)
can give different results for the same image. The two constructions are almost
dual to each other, and we use this relationship to extend and modify the cubical
complexes to become dual filtered cell complexes. We derive a general relationship
between the persistent homology of two dual filtered cell complexes, and also
establish how various modifications to a filtered complex change the persistence
diagram. Applying these results to images, we derive a method to transform the
persistence diagram computed using one type of cubical complex into a persistence
diagram for the other construction. This means software for computing persistent
homology from images can now be easily adapted to produce results for either of
the two cubical complex constructions without additional low-level code implementation.

text: "We classify contravariant pairings between standard Whittaker modules and
Verma modules over a complex semisimple Lie algebra. These contravariant pairings
are useful in extending several classical techniques for category O to the Miličić–Soergel
category N . We introduce a class of costandard modules which generalize dual
Verma modules, and describe canonical maps from standard to costandard modules
in terms of contravariant pairings.\r\nWe show that costandard modules have unique
irreducible submodules and share the same composition factors as the corresponding
standard Whittaker modules. We show that costandard modules give an algebraic
characterization of the global sections of costandard twisted Harish-Chandra sheaves
on the associated flag variety, which are defined using holonomic duality of D-modules.
We prove that with these costandard modules, blocks of category\r\nN have the
structure of highest weight categories and we establish a BGG reciprocity theorem
for N ."

text: The depth of a cell in an arrangement of n (non-vertical) great-spheres in
Sd is the number of great-spheres that pass above the cell. We prove Euler-type
relations, which imply extensions of the classic Dehn–Sommerville relations for
convex polytopes to sublevel sets of the depth function, and we use the relations
to extend the expressions for the number of faces of neighborly polytopes to the
number of cells of levels in neighborly arrangements.

text: 'We characterize critical points of 1-dimensional maps paired in persistent
homology geometrically and this way get elementary proofs of theorems about the
symmetry of persistence diagrams and the variation of such maps. In particular,
we identify branching points and endpoints of networks as the sole source of asymmetry
and relate the cycle basis in persistent homology with a version of the stable
marriage problem. Our analysis provides the foundations of fast algorithms for
maintaining collections of interrelated sorted lists together with their persistence
diagrams. '

text: "Isomanifolds are the generalization of isosurfaces to arbitrary dimension
and codimension, i.e. manifolds defined as the zero set of some multivariate vector-valued
smooth function f : Rd → Rd−n. A natural (and efficient) way to approximate an
isomanifold is to consider its Piecewise-Linear (PL) approximation based on a
triangulation T of the ambient space Rd. In this paper, we give conditions under
which the PL-approximation of an isomanifold is topologically equivalent to the
isomanifold. The conditions are easy to satisfy in the sense that they can always
be met by taking a sufficiently\r\nfine triangulation T . This contrasts with
previous results on the triangulation of manifolds where, in arbitrary dimensions,
delicate perturbations are needed to guarantee topological correctness, which
leads to strong limitations in practice. We further give a bound on the Fréchet
distance between the original isomanifold and its PL-approximation. Finally we
show analogous results for the PL-approximation of an isomanifold with boundary."

text: It is practical to collect a huge amount of movement data and environmental
context information along with the health signals of individuals because there
is the emergence of new generations of positioning and tracking technologies and
rapid advancements of health sensors. The study of the relations between these
datasets and their sequence similarity analysis is of interest to many applications
such as health monitoring and recommender systems. However, entering all movement
parameters and health signals can lead to the complexity of the problem and an
increase in its computational load. In this situation, dimension reduction techniques
can be used to avoid consideration of simultaneous dependent parameters in the
process of similarity measurement of the trajectories. The present study provides
a framework, named CaDRAW, to use spatial–temporal data and movement parameters
along with independent context information in the process of measuring the similarity
of trajectories. In this regard, the omission of dependent movement characteristic
signals is conducted by using an unsupervised feature selection dimension reduction
technique. To evaluate the effectiveness of the proposed framework, it was applied
to a real contextualized movement and related health signal datasets of individuals.
The results indicated the capability of the proposed framework in measuring the
similarity and in decreasing the characteristic signals in such a way that the
similarity results -before and after reduction of dependent characteristic signals-
have small differences. The mean differences between the obtained results before
and after reducing the dimension were 0.029 and 0.023 for the round path, respectively.

text: Motivated by the recent introduction of the intrinsic semilattice entropy,
we study generalized quasi-metric semilattices and their categories. We investigate
the relationship between these objects and generalized semivaluations, extending
Nakamura and Schellekens' approach. Finally, we use this correspondence to compare
the intrinsic semilattice entropy and the semigroup entropy induced in particular
situations, like sets, torsion abelian groups and vector spaces.

text: A matching is compatible to two or more labeled point sets of size n with
labels {1, . . . , n} if its straight-line drawing on each of these point sets
is crossing-free. We study the maximum number of edges in a matching compatible
to two or more labeled point sets in general position in the plane. We show that
for any two labeled sets of n points in convex position there exists a compatible
matching with ⌊√2n + 1 − 1⌋ edges. More generally, for any ℓ labeled point sets
we construct compatible matchings of size Ω(n1/ℓ). As a corresponding upper bound,
we use probabilistic arguments to show that for any ℓ given sets of n points there
exists a labeling of each set such that the largest compatible matching has O(n2/(ℓ+1))
edges. Finally, we show that Θ(log n) copies of any set of n points are necessary
and sufficient for the existence of labelings of these point sets such that any
compatible matching consists only of a single edge.

text: Point-set topology is among the most abstract branches of mathematics in that
it lacks tangible notions of distance, length, magnitude, order, and size. There
is no shape, no geometry, no algebra, and no direction. Everything we are used
to visualizing is gone. In the teaching and learning of mathematics, this can
present a conundrum. Yet, this very property makes point set topology perfect
for teaching and learning abstract mathematical concepts. It clears our minds
of preconceived intuitions and expectations and forces us to think in new and
creative ways. In this paper, we present guided investigations into topology through
questions and thinking strategies that open up fascinating problems. They are
intended for faculty who already teach or are thinking about teaching a class
in topology or abstract mathematical reasoning for undergraduates. They can be
used to build simple to challenging projects in topology, proofs, honors programs,
and research experiences.

text: We investigate a sheaf-theoretic interpretation of stratification learning
from geometric and topological perspectives. Our main result is the construction
of stratification learning algorithms framed in terms of a sheaf on a partially
ordered set with the Alexandroff topology. We prove that the resulting decomposition
is the unique minimal stratification for which the strata are homogeneous and
the given sheaf is constructible. In particular, when we choose to work with the
local homology sheaf, our algorithm gives an alternative to the local homology
transfer algorithm given in Bendich et al. (Proceedings of the 23rd Annual ACM-SIAM
Symposium on Discrete Algorithms, pp. 1355–1370, ACM, New York, 2012), and the
cohomology stratification algorithm given in Nanda (Found. Comput. Math. 20(2),
195–222, 2020). Additionally, we give examples of stratifications based on the
geometric techniques of Breiding et al. (Rev. Mat. Complut. 31(3), 545–593, 2018),
illustrating how the sheaf-theoretic approach can be used to study stratifications
from both topological and geometric perspectives. This approach also points toward
future applications of sheaf theory in the study of topological data analysis
by illustrating the utility of the language of sheaf theory in generalizing existing
algorithms.

text: When can a polyomino piece of paper be folded into a unit cube? Prior work
studied tree-like polyominoes, but polyominoes with holes remain an intriguing
open problem. We present sufficient conditions for a polyomino with one or several
holes to fold into a cube, and conditions under which cube folding is impossible.
In particular, we show that all but five special “basic” holes guarantee foldability.

text: Canonical parametrisations of classical confocal coordinate systems are introduced
and exploited to construct non-planar analogues of incircular (IC) nets on individual
quadrics and systems of confocal quadrics. Intimate connections with classical
deformations of quadrics that are isometric along asymptotic lines and circular
cross-sections of quadrics are revealed. The existence of octahedral webs of surfaces
of Blaschke type generated by asymptotic and characteristic lines that are diagonally
related to lines of curvature is proved theoretically and established constructively.
Appropriate samplings (grids) of these webs lead to three-dimensional extensions
of non-planar IC nets. Three-dimensional octahedral grids composed of planes and
spatially extending (checkerboard) IC-nets are shown to arise in connection with
systems of confocal quadrics in Minkowski space. In this context, the Laguerre
geometric notion of conical octahedral grids of planes is introduced. The latter
generalise the octahedral grids derived from systems of confocal quadrics in Minkowski
space. An explicit construction of conical octahedral grids is presented. The
results are accompanied by various illustrations which are based on the explicit
formulae provided by the theory.
