Band Topology and Linking Structure of Nodal Line Semimetals with Z_{2} Monopole Charges. [PDF]

open access: yesPhysical Review Letters, 2018
We study the band topology and the associated linking structure of topological semimetals with nodal lines carrying Z_{2} monopole charges, which can be realized in three-dimensional systems invariant under the combination of inversion P and time ...

Nodal signalling in Xenopus: the role of Xnr5 in left/right asymmetry and heart development [PDF]

open access: yesOpen Biology, 2016
Nodal class TGF-β signalling molecules play essential roles in establishing the vertebrate body plan. In all vertebrates, nodal family members have specific waves of expression required for tissue specification and axis formation.

Rapid changes in morphogen concentration control self-organized patterning in human embryonic stem cells

open access: yeseLife, 2019
During embryonic development, diffusible signaling molecules called morphogens are thought to determine cell fates in a concentration-dependent way.

Nodal and planar cell polarity signaling cooperate to regulate zebrafish convergence and extension gastrulation movements

open access: yeseLife, 2020
During vertebrate gastrulation, convergence and extension (C and E) of the primary anteroposterior (AP) embryonic axis is driven by polarized mediolateral (ML) cell intercalations and is influenced by AP axial patterning. Nodal signaling is essential for

Imaging nodal knots in momentum space through topolectrical circuits [PDF]

open access: yesNature Communications, 2019
Knots are intricate structures that cannot be unambiguously distinguished with any single topological invariant. Momentum space knots, in particular, have been elusive due to their requisite finely tuned long-ranged hoppings. Even if constructed, probing

Early nodal and extra-nodal non-Hodgkin's lymphomas [PDF]

open access: yesCancer, 1977
There were 54 Stage I and 38 Stage II patients with non-Hodgkin's lymphomas treated with curative radiotherapy between 1964 and 1975. The initial biopsy material was reclassified according to the criteria of Rappaport el at.10 The frequency of nodular vs diffuse histological pattern was 26% vs 74%.
