Diagnostyka postnatalna wad układu moczowego wykrytych w okresie prenatalnym. Część 2. Zmiany w miąższu nerek

open access: yesPediatria i Medycyna Rodzinna, 2010
Wady wrodzone układu moczowego stanowią znaczącą grupę wad, które mogą być wykryte prenatalnie. Oprócz nieprawidłowych obrazów dróg wyprowadzających mocz stwierdza się również nieprawidłowości w zakresie ilości i struktury miąższu nerkowego ...

Common Signatures of Altered Gene Regulation and Invasiveness of Different Breast Cancer Cell Lines after Matrix Interface Crossing

open access: yesAdvanced Healthcare Materials, EarlyView.
Interface transmigration reprograms triple‐negative breast cancer cells, triggering a shared switch toward more aggressive and invasive phenotypes. Using a collagen I interface model, this study identifies shared transcriptional changes involving proliferation, chromatin remodeling, and DNA repair pathways.

Limits on orbit crossing planetesimals in the resonant multiple planet system, KOI-730

open access: yes, 2012
A fraction of multiple planet candidate systems discovered from transits by the Kepler mission contain pairs of planet candidates that are in orbital resonance or are spaced slightly too far apart to be in resonance.

Ligand‐Mediated Surface Carrier Modulation in Perovskite Nanocrystals for Charge‐Symmetric LEDs

open access: yesAdvanced Materials, EarlyView.
A hydrolysis‐assisted ligand exchange strategy enables surface carrier modulation of perovskite nanocrystals using a multifunctional π‐conjugated ligand. This molecular surface design achieves charge balance and recombination‐zone symmetry in light‐emitting diodes (LEDs), which leads to high‐efficiency perovskite LEDs and establishes a general platform

Critical Behaviour of integrable mixed spins chains

open access: yes, 1993
We construct a mixed spin 1/2 and $S$ integrable model and investigate its finite size properties. For a certain conformal invariant mixed spin system the central charge can be decomposed in terms of the conformal anomaly of two single integrable models ...

Data‐Driven Discovery of Quaternary Ammonium Interlayers for Efficient and Thermally Stable Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
An active learning framework, grounded in independently generated in‐house experimental data, enables reliable discovery of high‐performance interfacial materials for perovskite solar cells. Iterative model refinement autonomously converges toward structurally robust quaternary ammonium architectures, establishing a new design principle for interfacial
