Physical Review Accelerators and BeamsIn typical studies of collective effects in a storage ring, an important assumption is that the longitudinal bunch length remains constant over one turn, which is referred to as the adiabatic approximation.

Capturing spiral radial growth of conifers using the superellipse to model tree-ring geometric shape
Frontiers in Plant Science, 2015 Tree-rings are often assumed to approximate a circular shape when estimating forest productivity and carbon dynamics. However, tree rings are rarely, if ever, circular, thereby possibly resulting in under- or over-estimation in forest productivity and ...

Molecular Oncology, EarlyView.Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Online optimization of storage ring nonlinear beam dynamics
Physical Review Special Topics. Accelerators and Beams, 2015 We propose to optimize the nonlinear beam dynamics of existing and future storage rings with direct online optimization techniques. This approach may have crucial importance for the implementation of diffraction limited storage rings.

Hadronic processes at small angles in storage rings Proceedings
, 1993 Cooler Synchrotron and Storage Rings and their circulating very intense cold beams with high phase space density allow the study - in the nonperturbative QCD regime - of hadronic processes which cannot be investigated by other means.

Depolarisation in large electron storage rings
, 1976 It is shown from elementary considerations that polarised beams of electrons or positrons are unlikely to be obtained in storage rings much above about 30 GeV in top energy.

Molecular Oncology, EarlyView.Circulating microRNAs as biomarkers of cachexia and sex‐specific cancer in senior dogs. In 25 client‐owned dogs, four circulating miRNAs (miR‐15a, miR‐15b, miR‐16, miR‐140) were downregulated in cachexia, with miR‐16 the strongest individual biomarker (AUC = 0.899).

Molecular Oncology, EarlyView.This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer
Molecular Oncology, EarlyView.Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Trapped macroparticles in electron storage rings
, 1995 Sudden drops of the beam lifetime ascribed to the capture of positively charged macroparticles (‘dust’) are observed at many high-energy electron storage rings.
