Liver Metastases from Colorectal Cancer: From Pathogenesis to Current Treatment
MedComm, Volume 7, Issue 10, October 2026.The liver is not merely a passive recipient of disseminated tumor cells, but a unique metastatic organ shaped by anatomical, metabolic, and immunological characteristics that support tumor colonization. Increasing evidence indicates that colorectal cancer liver metastasis development is driven by dynamic interactions between tumor intrinsic programs ...

Gravitational wave detection and data analysis for pulsar timing arrays [PDF]
, 2011 Long-term precise timing of Galactic millisecond pulsars holds great promise for measuring long-period (months-to-years) astrophysical gravitational waves.

Life‐stage variation in Sable Shearwater (Ardenna carneipes) physiology assessed using proteomics
Ibis, Volume 168, Issue 4, Page 1500-1515, October 2026.Life‐stage transitions in seabirds involve substantial shifts in physiological demands, yet the molecular mechanisms underpinning these changes remain poorly resolved. Here we applied untargeted data‐independent acquisition mass spectrometry (DIA‐MS) to characterize and compare the plasma proteomes of fledgling and adult Sable Shearwaters Ardenna ...

A relativistic positioning system exploiting pulsating sources for navigation across the Solar System and beyond [PDF]
, 2011 We introduce an operational approach to the use of pulsating sources, located at spatial infinity, for defining a relativistic positioning and navigation system, based on the use of null four-vectors in a flatMinkowskian spacetime.

Rfi Mitigation Implementation For Pulsar Radioastronomy
, 2010 International audienceThe observation of known pulsars (pulsar timing) or the search for new pulsars can be limited by radio frequency interference (RFI) generated by Telecommunications activity. In this paper we propose several RFI mitigation techniques

A Novel Technique for Long-term Timing of Redback Millisecond Pulsars
The Astrophysical JournalWe present timing solutions spanning nearly two decades for five redback (RB) systems found in globular clusters (GCs), created using a novel technique that effectively “isolates” the pulsar. By accurately measuring the time of passage through periastron

Pulsar timing and spacetime curvature [PDF]
, 2009 We analyze the effect of weak field gravitational waves on the timing of pulsars, with particular attention to gauge invariance, that is, to the effects that are independent of the choice of coordinates.
