Designing B1‐Selective Pulses by Frequency Modulating in a Second Rotating Frame
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To create a frequency‐modulated pulse for slice selection of arbitrary, uniform flip angle even when B0 and B1 are inhomogeneous, without utilizing B0 gradients Theory and Methods An amplitude‐modulated hyperbolic secant pulse (AMHS1) was derived from Hoult's B1‐selective imaging method which utilizes one component, B1y, as a gradient ...

The Distinctness of Objects Near and Far
Philosophy and Phenomenological Research, EarlyView.ABSTRACT Philosophers working on the metaphysics of persistence typically do not extend their views to the distinctness of objects at a single time. I argue that we can provide criteria to distinguish objects across time if and only if we can provide criteria to distinguish objects at a time. Furthermore, I endorse a stronger claim.

NLO radiative correction to the Casimir energy in Lorentz-violating scalar field theory
Nuclear Physics B, 2019 Violation of the Lorentz symmetry has important effects on physical quantities including field propagators. Therefore, in addition to the leading order, the sub-leading order of quantities may be modified. In this paper, we calculate the next to leading (

Electrodynamics with Lorentz-violating operators of arbitrary dimension [PDF]
, 2009 The behavior of photons in the presence of Lorentz and CPT violation is studied. Allowing for operators of arbitrary mass dimension, we classify all gauge-invariant Lorentz- and CPT-violating terms in the quadratic Lagrange density associated with the ...

Phenomenal knowledge and phenomenal causality
Noûs, Volume 60, Issue 1, Page 212-232, March 2026.Abstract There has been extensive debate over whether we can have phenomenal knowledge in the case of epiphenomenalism. This article aims to bring that debate to a close. I first develop a refined causal account of knowledge—one that is modest enough to avoid various putative problems, yet sufficiently robust to undermine the epiphenomenalist position.

The effect of Lorentz symmetry violation on the hadron fragmentation function
European Physical Journal C: Particles and FieldsDifferent processes have been yet considered to investigate the effects of Lorentz symmetry violation and various bounds have been determined for the magnitude of Lorentz violation (LV) coefficients.

Lorentz Symmetry and High-Energy Neutrino Astronomy
Universe, 2021 The search of the violation of Lorentz symmetry, or Lorentz violation (LV), is an active research field. The effects of LV are expected to be very small, and special systems are often used to search it.

CPT and Lorentz tests with muons [PDF]
, 1999 Precision experiments with muons are sensitive to Planck-scale CPT and Lorentz violation that is undetectable in other tests. Existing data on the muonium ground-state hyperfine structure and on the muon anomalous magnetic moment could be analyzed to ...
