Laboratory-based x-ray phase contrast microscopy system for targeting in unstained soft-tissue samples by Michela Esposito, Nicole Schieber, Alessandro Olivo, Yannick Schwab, Marco Endrizzi

“…We propose an imaging system and methodology for mapping soft-tissue samples in three dimensions, with micron-scale and isotropic spatial resolution, with low-concentrations as well as in the absence of heavy metal staining. We used hard x-ray phase-contrast imaging for the x-ray ability to nondestructively probe the internal structure of opaque specimens and for enhanced contrast obtained by exploiting phase effects, even in cases with reduced or absent staining agents. …”

Krylov complexity in 2d CFTs with SL(2, ℝ) deformed Hamiltonians by Vinay Malvimat, Somnath Porey, Baishali Roy

“…Notably, the precise exponent governing this growth depends on the heaviness of the state under examination. In the non-heating phase, we observe a transition in K-Complexity behaviour from oscillatory to exponential growth, akin to findings in [1], as it represents a special case within the non-heating phase.…”

Antibody-epitope conjugates deliver immunogenic T-cell epitopes more efficiently when close to cell surfaces by W. van der Wulp, W. Luu, M. E. Ressing, J. Schuurman, S. I. van Kasteren, L. Guelen, R. C. Hoeben, B. Bleijlevens, M. H. M. Heemskerk

“…AECs carrying epitopes genetically fused at the N-terminus of the light chains of cetuximab and trastuzumab demonstrate an even more efficient delivery of the T-cell epitopes compared to AECs with the epitope fused to the C-terminus of the heavy chain. We demonstrate that this increased efficiency is not caused by the shift in location of the cleavage site from the N- to the C-terminus, but by its increased proximity to the cell surface. …”
