Design of the 12-bit Delta-Sigma Modulator using SC Technique for Vibration Sensor Output Processing [PDF]
Radioengineering, 2012 The work deals with the design of the 12-bit Delta-Sigma modulator using switched capacitors (SC) technique. The modulator serves to vibration sensor output processing. The first part describes the Delta-Sigma modulator parameters definition.

Advances in Theoretical and Mathematical Physics, 2023 We show that sigma models with orthogonal and symplectic Grassmannian target spaces admit chiral Gross-Neveu model formulations, thus extending earlier results on unitary Grassmannians.

Fractional particle and sigma model
Journal of High Energy PhysicsWe introduce a classical fractional particle model in ℝ n , extending the Newtonian particle concept with the incorporation of the fractional Laplacian.

Universality of a truncated sigma-model
Physics Letters B, 2022 Bosonic quantum field theories, even when regularized using a finite lattice, possess an infinite dimensional Hilbert space and, therefore, cannot be simulated in quantum computers with a finite number of qubits. A truncation of the Hilbert space is then

Higgs inflation as nonlinear sigma model and scalaron as its σ-meson [PDF]
Journal of High Energy Physics, 2020 We point out that a model with scalar fields with a large nonminimal coupling to the Ricci scalar, such as Higgs inflation, can be regarded as a nonlinear sigma model (NLSM). With the inclusion of not only the scalar fields but also the conformal mode of

Born sigma model for branes in exceptional geometry [PDF]
Progress of Theoretical and Experimental Physics, 2020 In double field theory, the physical space has been understood as a subspace of the doubled space. Recently, the doubled space has been defined as the para-Hermitian manifold and the physical space is realized as a leaf of a foliation of the doubled ...

Courant Sigma Model and L∞ ‐algebras [PDF]
Fortschritte der Physik, 2020 The Courant sigma model is a 3‐dimensional topological sigma model of AKSZ type which has been used for the systematic description of closed strings in non‐geometric flux backgrounds.

Sigma-Lognormal Modeling of Speech [PDF]
Cognitive Computation, 2021 AbstractHuman movement studies and analyses have been fundamental in many scientific domains, ranging from neuroscience to education, pattern recognition to robotics, health care to sports, and beyond. Previous speech motor models were proposed to understand how speech movement is produced and how the resulting speech varies when some parameters are ...

SciPost Physics, 2019 We study (1+1)-dimensional non-linear sigma models whose target space is the flag manifold U(N)\over U(N_1)\times U(N_2)\cdots U(N_m), with a specific focus on the special case U(N)/U(1)^{N}U(N)/U(1)N. These generalize the well-known \mathbb{CP}^{N-1}ℂℙN−1 model.

Anomaly and global inconsistency matching: θ angles, SU(3)/U(1)2 nonlinear sigma model, SU(3) chains, and generalizations [PDF]
Physical review B, 2018 We discuss the SU(3)/[U(1)×U(1)] nonlinear sigma model in 1+1D and, more broadly, its linearized counterparts. Such theories can be expressed as U(1)×U(1) gauge theories and therefore allow for two topological θ angles.
