Witkacy and His Doppelgängers

open access: yesEidos. A Journal for Philosophy of Culture, 2019
The literary work of Stanisław I. Witkiewicz (Witkacy), whose world career began in the fifties of the last century, is considered today in many aspects as precursory to postmodernism.

Unveiling the Taxonomic Diversity and Unprecedented Biosynthetic Treasure of the Phylum Myxococcota

open access: yesAdvanced Science, EarlyView.
Natural products remain vital sources of therapeutics, and the phylum Myxococcota constitutes an especially rich reservoir for them. Based on decades of microbiological efforts, we present 154 new Myxococcota genomes and revise taxonomy quadrupling the number of families and genera.

Combinatorial Legendrian knot invariants : representation numbers

open access: yes, 2019
The study of Legendrian knots lies within the larger elds of contact geometry and knot theory. The requirements for Legendrian invariance is strictly stronger than its topological analog, as there are Legendrian knots that are not Legendrian isotopic,

Paraborg: Paramedic Cyborg Insects for In Situ Emergency Drug‐Delivery

open access: yesAdvanced Science, EarlyView.
This work introduces Paraborg, a human‐supervised paramedic cyborg‐insect platform that combines controllable locomotion, onboard imaging, and an auto‐injection mechanism for in situ drug‐delivery. By demonstrating reliable navigation, target stabilization, injector launch, and multi‐insect teamwork, the study extends cyborg insects from survivor ...

Mechanical Signatures of Nucleic Acid Trefoil Knot Topology

open access: yesAngewandte Chemie, EarlyView.
Single‐stranded DNA can be designed with sequences that self‐thread into topological knots. The exact same sequence can alternatively be turned into an unknotted pseudoknot. The topology of the resulting polymer is determined by applying force with optical tweezers, causing the pseudoknot to resolve but the knot to tighten.

Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies

open access: yesAdvanced Science, EarlyView.
A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.

Knot-theoretic ternary quasigroup theory and shadow biquandle theory for oriented surface-knots

open access: yes, 2020
A knot-theoretic ternary quasigroup is an algebraic system which equips a ternary operation coming from oriented (surface-)knot diagrams with region labelings.

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

open access: yesAngewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

The effect of seed age and treatment by Proradix method on germinability and initial growth of selected meadow grass (Poa pratensis) varieties

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
The goal of the study conducted in 2008 and 2010 at the Research Forage Production Station in Vatín was to investigate the influence of seed age and seed treatment by Proradix method on the germination dynamics, total germinating capacity and initial ...
