Ethnography, Memory, Experiment: Towards an Alternative Social History of Poland

open access: yesTeksty Drugie, 2023
Research on the self-organization and creative potential of rural communities in Poland suggests several decades of unrecognized conflicts of knowledge and social identity. This article demonstrates how work that is experimental both ethnographically and

Polish Metric Spaces: Their Classification and Isometry Groups [PDF]

open access: yesBulletin of Symbolic Logic, 2001
§ 1. Introduction. In this communication we present some recent results on the classification of Polish metric spaces up to isometry and on the isometry groups of Polish metric spaces. A Polish metric space is a complete separable metric space (X, d).Our first goal is to determine the exact complexity of the classification problem of general Polish ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Beginning of stability theory for Polish spaces [PDF]

open access: yesIsrael Journal of Mathematics, 2016
We consider stability theory for Polish spaces and more generally for definable structures (say, with elements of a set of reals). We clarify by proving some equivalent conditions for $\aleph_0$-stability. We succeed to prove existence of indiscernibles under reasonable conditions; this gives strong evidence that such a theory exists.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Linguistic landscapes in transition: Polish students’ views on Ukrainian and Russian signage

open access: yesGlottodidactica
In today’s globalised world, the presence of foreign languages and signs is not unusual. However, during periods of conflict, these linguistic features gain particular significance, including linguistic landscapes.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Polish Migrants in Urban Space of Dublin [PDF]

open access: yesBulletin of Geography. Socio-economic Series, 2011
The end of Cold War in the late 1980s of the 20 th century and the accession to EU in 2004 brought spectacular changes in Polish migrations during the last 20 years. The opening of borders in 1989 and labour markets for Poles in 2004 caused fundamental changes in the scale, intensity and directions of Polish migrations.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
