We show that the position-momentum duality offers a transparent interpretation of band geometry at topological crossings. Under this duality, with Berry connection is dual to free-electron motion under gauge field. This identifies trace quantum metric as energy in momentum space. The crossings defects thus induce quantization metric. For $\mathbb{Z}$ nodal-point and nodal-surface semimetals thr...

In this work we study thermodynamic manifestations of the quantum criticality in multiband unconventional superconductors. As a guiding example consider scenario magnetic critical point model that captures superconductivity coexistence with spin-density wave. We show situations when superconducting order parameter has incidental nodes at isolated points, fluctuations lead to renormalization rel...

In this paper, an inverse nodal problem for a second-order differential equation having a chemical potential on a finite interval is investigated. First, we estimate the nodal points and nodal lengths of differential operator. Then, we show that the potential can be uniquely determined by a dense set of nodes of the eigenfunctions.

Assessing the geomagnetic hazard to power systems requires reliable modelling of the geomagnetically induced currents (GIC) produced in the power network. This paper compares the Nodal Admittance Matrix method with the Lehtinen–Pirjola method and shows them to be mathematically equivalent. GIC calculation using the Nodal Admittance Matrix method involves three steps: (1) using the voltage sourc...

background: axillary nodal spread is an established prognostic factor in breast cancer. axillary nodal dissection and subsequent pathological examination is considered the gold standard technique of assessing the axilla for metastatic disease. a minimum of ten level i axillary nodes are required to be examined before an axillary specimen can be reliably labeled as disease free. this recommendat...

The sinoatrial (SA) and atrioventricular (AV) nodes are specialized centers of the heart conduction system and are composed of muscle cells with distinctive morphological and electrophysiological properties. We report here results of immunofluorescence and immunoperoxidase studies on the bovine heart showing that a large number of SA and AV nodal cells share a distinct type of myosin heavy chai...

Abstract The Linear Smoothing (LS) scheme [1] ameliorates linear and quadratic approximations over convex polytopes by employing a three-point integration scheme. In this work, we propose a linearly consistent one point integration scheme which possesses the properties of the LS scheme with three integration points but requires one third of the integration computational time. The essence of the...

We derive recursive equations for the characteristic numbers of rational nodal plane curves with at most one cusp, subject to point conditions, tangent conditions and flag conditions, developing techniques akin to quantum cohomology on a moduli space of stable lifts.
