Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

Towards Verified, Constant-time Floating Point Operations [PDF]

Proceedings of the 2018 ACM SIGSAC Conference on Computer and Communications Security, 2018
The runtimes of certain floating-point instructions can vary up to two orders of magnitude with instruction operands, allowing attackers to break security and privacy guarantees of real systems (\eg browsers). To prevent attacks due to such floating-point timing channels, we introduce CTFP, an efficient, machine-checked, and extensible system that ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
