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.","lang":"eng"}],"month":"06","intvolume":" 224","scopus_import":"1","file":[{"file_name":"2022_LIPICs_Chambers.pdf","date_created":"2022-06-07T07:58:30Z","file_size":17580705,"date_updated":"2022-06-07T07:58:30Z","creator":"dernst","success":1,"file_id":"11437","checksum":"b25ce40fade4ebc0bcaae176db4f5f1f","content_type":"application/pdf","relation":"main_file","access_level":"open_access"}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["1868-8969"],"isbn":["978-3-95977-227-3"]},"publication_status":"published","volume":224,"ec_funded":1,"_id":"11428","series_title":"LIPIcs","status":"public","type":"conference","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"conference":{"name":"SoCG: Symposium on Computational Geometry","start_date":"2022-06-07","location":"Berlin, Germany","end_date":"2022-06-10"},"ddc":["510"],"date_updated":"2023-02-21T09:50:52Z","file_date_updated":"2022-06-07T07:58:30Z","department":[{"_id":"HeEd"}],"acknowledgement":"Partially supported by the DFG Collaborative Research Center TRR 109, “Discretization in Geometry and Dynamics” and the European Research Council (ERC), grant no. 788183, “Alpha Shape Theory Extended”.

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.","lang":"eng"}],"oa_version":"Preprint","main_file_link":[{"open_access":"1","url":" https://doi.org/10.48550/arXiv.2102.11397"}],"scopus_import":"1","alternative_title":["Association for Women in Mathematics Series"],"intvolume":" 30","month":"01","place":"Cham","publication_status":"published","publication_identifier":{"eisbn":["9783030955199"],"isbn":["9783030955182"]},"language":[{"iso":"eng"}],"ec_funded":1,"volume":30,"_id":"11440","series_title":"AWMS","type":"book_chapter","status":"public","date_updated":"2022-06-07T08:32:42Z","department":[{"_id":"HeEd"}],"acknowledgement":"This project started during the Women in Computational Topology workshop held in Canberra in July of 2019.

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.","lang":"eng"}],"intvolume":" 32","month":"05","scopus_import":"1","date_updated":"2023-01-30T13:02:30Z","department":[{"_id":"HeEd"},{"_id":"GradSch"}],"_id":"12307","keyword":["Education","General Mathematics"],"status":"public","type":"journal_article","article_type":"original"},{"citation":{"ista":"Aichholzer O, Arroyo Guevara AM, Masárová Z, Parada I, Perz D, Pilz A, Tkadlec J, Vogtenhuber B. 2022.

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.

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.","lang":"eng"}],"oa_version":"Published Version","scopus_import":"1","month":"02","intvolume":" 23","date_updated":"2023-08-09T10:17:07Z","ddc":["510","576"],"department":[{"_id":"HeEd"}],"file_date_updated":"2022-02-14T07:46:30Z","_id":"10754","type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"status":"public","isi":1,"has_accepted_license":"1","year":"2022","day":"01","publication":"International Journal of Molecular Sciences","date_published":"2022-02-01T00:00:00Z","doi":"10.3390/ijms23031763","date_created":"2022-02-13T23:01:35Z","acknowledgement":"This work was partially supported by grants from National Institutes of Health (NIH) (R01 CA185055, S10OD0252300) and The University of Texas System STARs Award (to Z.P.),\r\nThe University of Texas at Arlington Interdisciplinary Research Program (to B.C., H.V.K. and Z.P.).

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.","lang":"eng"}],"volume":13,"language":[{"iso":"eng"}],"file":[{"file_id":"10279","checksum":"0a8961416a9bb2be5a1cebda65468bcf","embargo":"2022-11-12","access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2021-11-12T19:38:05Z","file_name":"A Context‑aware Dimension Reduction Framework - Journal of Ambient Intelligence 2021 (Preprint version).pdf","creator":"fkarimip","date_updated":"2022-12-20T23:30:08Z","file_size":1634958}],"publication_status":"published","publication_identifier":{"eissn":["1868-5145"],"issn":["1868-5137"]}}]
