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

Cold Spring Harbor Perspectives in Biology, 2009 Nodal signals belong to the TGF-beta superfamily and are essential for the induction of mesoderm and endoderm and the determination of the left-right axis. Nodal signals can act as morphogens-they have concentration-dependent effects and can act at a distance from their source of production.

Nodal quintic threefolds and nodal octic surfaces [PDF]
Proceedings of the American Mathematical Society, 1990 The relation between the nodes and the defect of nodal quintic threefolds or double solids ramified over nodal octic surfaces has implications on the existence of such varieties with fewer nodes.

Frontiers in Cardiovascular Medicine, 2023 ObjectiveCongenital heart disease (CHD) is caused by cardiovascular developmental defects and has a global prevalence of ∼1%. The etiology of CHD is multifactorial and remains generally unknown, despite advances in analytical techniques based on next ...

The dynamic right-to-left translocation of Cerl2 is involved in the regulation and termination of nodal activity in the mouse node [PDF]
, 2013 The determination of left-right body asymmetry in mouse embryos depends on the interplay of molecules In a highly sensitive structure, the node. Here, we show that the localization of Cerl2 protein does not correlate to its mRNA expression pattern, from ...

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

Topological nodal-line fermions in spin-orbit metal PbTaSe2
Nature Communications, 2016 Topological semimetals can support one-dimensional Fermi lines or zero-dimensional Weyl points in momentum space, where the valence and conduction bands touch.

Symmetry-protected nodal phases in non-Hermitian systems [PDF]
Physical review B, 2018 Symmetry plays a paramount role for the classification of phases of matter occurring in nature. Combining symmetry analysis with concepts from topology that allow us to identify global and robust physical properties, new phases of quantum matter, such as

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