PT-symmetry and Integrability [PDF]

open access: yesActa Polytechnica, 2007
We briefly explain some simple arguments based on pseudo Hermiticity, supersymmetry and PT-symmetry which explain the reality of the spectrum of some non-Hermitian Hamiltonians.

Reply to Horta: Spectrum Arguments, the “Unhelpfulness” of Rejecting Transitivity, and Implications for Moral Realism

open access: yesLaw, Ethics and Philosophy, 2015
This article responds to Oscar Horta’s article “In Defense of the Internal Aspects View: Person-Affecting Reasons, Spectrum Arguments and Inconsistent Intuitions”. I begin by noting various points of agreement with Horta.

In Defense of the Internal Aspects View: Person-Affecting Reasons, Spectrum Arguments and Inconsistent Intuitions

open access: yesLaw, Ethics and Philosophy, 2015
According to the Internal Aspects View, the value of different outcomes depends solely on the internal features possessed by each outcome and the internal relations between them. This paper defends the Internal Aspects View against Larry Temkin’s defence

Signatures of neutral evolution in exponentially growing tumors: A theoretical perspective.

open access: yesPLoS Computational Biology, 2021
Recent work of Sottoriva, Graham, and collaborators have led to the controversial claim that exponentially growing tumors have a site frequency spectrum that follows the 1/f law consistent with neutral evolution. This conclusion has been criticized based

Reconstruction of Differential Operators with Frozen Argument

open access: yesAxioms, 2022
We study spectral properties of a wide class of differential operators with frozen arguments by putting them into a general framework of rank-one perturbation theory.

Spectrum Aliasing Does not Occur in Case of Ideal Signal Sampling [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2021
A new model of ideal signal sampling operation is developed in this paper. This model does not use the Dirac comb in an analytical description of sampled signals in the continuous time domain. Instead, it utilizes functions of a continuous time variable,
