Models of Type Theory Based on Moore Paths [PDF]

open access: yesLogical Methods in Computer Science, 2019
This paper introduces a new family of models of intensional Martin-L\"of type theory. We use constructive ordered algebra in toposes. Identity types in the models are given by a notion of Moore path.

The Unification of Mathematics via Topos Theory

open access: yes, 2022
We present a set of principles and methodologies which may serve as foundations of a unifying theory of Mathematics. These principles are based on a new view of Grothendieck toposes as unifying spaces being able to act as `bridges' for transferring information, ideas and results between distinct mathematical theories.

Strong phylogenetic congruence between Tulasnella fungi and their associated Drakaeinae orchids

open access: yesJournal of Evolutionary Biology, Volume 36, Issue 1, Page 221-237, January 2023., 2023
Representatives of five genera of Drakaeinae orchids, from top left to bottom right: Arthrochilus latipes, Chiloglottis trilabra, Caleana major, Paracaleana minor, Drakaea livida. Abstract The study of congruency between phylogenies of interacting species can provide a powerful approach for understanding the evolutionary history of symbiotic ...

Variable DNA topology is an epigenetic generator of physiological heterogeneity in bacterial populations

open access: yesMolecular Microbiology, Volume 119, Issue 1, Page 19-28, January 2023., 2023
Positive supercoils in DNA impede transcription: (a) failure to relax positive supercoils halts transcription elongation; (b) removal of the supercoils facilitates transcription. Abstract Transcription is a noisy and stochastic process that produces sibling‐to‐sibling variations in physiology across a population of genetically identical cells.

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Facile Fabrication of Large‐Area and High‐Quality Organic–Inorganic Hybrid Perovskite Ferroelectric Films Through Electrohydrodynamic Printing

open access: yesAdvanced Science, EarlyView.
In situ fabrication of large‐area, high‐quality organic‐inorganic hybrid perovskite ferroelectric (OIHPF) crystals and films via on‐demand electrohydrodynamic (EHD) printing modes. Abstract Traditional oxide ferroelectrics have long struggled to produce flexible, large‐area, and high‐quality thin films at low temperatures, despite their good ...

Mineral oil interferes with potato virus Y in aphid stylets

open access: yesPlant Pathology, Volume 72, Issue 1, Page 170-178, January 2023., 2023
The mineral oil and the virus were visualized inside the insect's stylets and the mechanism by which the oil impacts virus acquisition seems to take place in the very early stages of acquisition. Abstract Mineral oils have been used for many decades to control the transmission of plant viruses and their ensuing epidemics.

Kant and new mathematics 100 years later [PDF]

open access: yesКантовский сборник, 2015
Cassirer’s critique of Russell’s philosophy of mathematics and the Neo-Kantian philosophy of science and mathematics as a whole is of special relevance in the context of modern mathematics and mathematical physics.
