Incorporating Curvature Information into On-line Learning [PDF]
, 1999 We analyse the dynamics of a number of second order on-line learning algorithms training multi-layer neural networks, using the methods of statistical mechanics. We first consider on-line Newton's method, which is known to provide optimal asymptotic performance.

Splitting the curvature of the determinant line bundle [PDF]
Proceedings of the American Mathematical Society, 1999 It is shown that the determinant line bundle associated to a family of Dirac operators over a closed partitioned manifold has a canonical Hermitian metric with compatible connection whose curvature satisfies an additivity formula with contributions from the families of Dirac operators over the two halves. This curvature form is the natural differential

Real-Time Curvature Measurement Sensor for Active Steering of Railroad Vehicles [PDF]
한국정밀공학회지, 2019 Conventional railroad vehicles, that run on a line with high frequency of sharp curves, have problems such as wheel noise and wear, from insufficient passive steering.

Berry curvature associated to Fermi arcs in continuum and lattice Weyl systems
Physical Review Research, 2023 Recently it has been discovered that in Weyl semimetals the surface state Berry curvature can diverge in certain regions of momentum. This occurs in a continuum description of tilted Weyl cones, which for a slab geometry results in the Berry curvature ...

A New Approach to Rotational Weingarten Surfaces
Mathematics, 2022 Weingarten surfaces are those whose principal curvatures satisfy a functional relation, whose set of solutions is called the curvature diagram or the W-diagram of the surface.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Relapsed and/or refractory (R/R) pediatric acute leukemia carries a dismal prognosis, largely driven by chemoresistance to conventional salvage therapy. The BH3‐mimetic venetoclax, combined with chemotherapy or hypomethylating agents, has demonstrated efficacy in small clinical trials.

Discrete curvature approximations and segmentation of polyhedral surfaces [PDF]
, 2005 The segmentation of digitized data to divide a free form surface into patches is one of the key steps required to perform a reverse engineering process of an object.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Outcomes in relapsed or refractory pediatric and AYA bone sarcomas remain poor, and the impact of early referral to specialized sarcoma centers on survival is unclear. Early centralization of care may improve local and systemic treatment quality, but evidence in this population is limited.

Differential phase tracking applied to Bragg gratings in multicore fiber for high accuracy curvature measurement [PDF]
, 2006 We report interferometric interrogation of fiber Bragg gratings in separate cores of a multicore fiber for high resolution quasi-static and dynamic bend measurements.

Do lattice data constrain the vector interaction strength of QCD?
Physics Letters B, 2014 We show how repulsive interactions of deconfined quarks as well as confined hadrons have an influence on the baryon number susceptibilities and the curvature of the chiral pseudo-critical line in effective models of QCD.
