Status of Baby Born to Brain-dead Mother: Ethical and Logical Issues

Studies in Logic, Grammar and Rhetoric, 2019
The study aims to analyse the clinical proceedings in pregnant women diagnosed with brain death. Apart from the diagnostic premises and the patient’s rights, the ontological status of the foetus proves to be a severe problem.

Randomized benchmarking in measurement-based quantum computing [PDF]

, 2016
Randomized benchmarking is routinely used as an efficient method for characterizing the performance of sets of elementary logic gates in small quantum devices.

Cellular Cohomology in Homotopy Type Theory [PDF]

, 2020
We present a development of cellular cohomology in homotopy type theory. Cohomology associates to each space a sequence of abelian groups capturing part of its structure, and has the advantage over homotopy groups in that these abelian groups of many ...

Notes on Isolated Horizons [PDF]

, 2000
A general analysis for characterizing and classifying `isolated horizons' is presented in terms of null tetrads and spin coefficients. The freely specifiable spin coefficients corresponding to isolated horizons are identified and specific symmetry ...

A note on inflation and transplanckian physics [PDF]

, 2002
In this paper we consider the influence of transplanckian physics on the CMBR anisotropies produced by inflation. We consider a simple toy model that allows for analytic calculations and argue on general grounds, based on ambiguities in the choice of ...

A 64-point Fourier transform chip for high-speed wireless LAN application using OFDM

, 2004
In this article, we present a novel fixed-point 16-bit word-width 64-point FFT/IFFT processor developed primarily for the application in the OFDM based IEEE 802.11a Wireless LAN (WLAN) baseband processor.

A Bayesian Analogue of Gleason's Theorem

, 2006
We introduce a novel notion of probability within quantum history theories and give a Gleasonesque proof for these assignments. This involves introducing a tentative novel axiom of probability.

Analytic control methods for high fidelity unitary operations in a weakly nonlinear oscillator

, 2011
In qubits made from a weakly anharmonic oscillator the leading source of error at short gate times is leakage of population out of the two dimensional Hilbert space that forms the qubit.

Bayesian Probabilities and the Histories Algebra

, 2006
We attempt a justification of a generalisation of the consistent histories programme using a notion of probability that is valid for all complete sets of history propositions.

Anderson localization and the topology of classifying spaces

, 2015
We construct the generic phase diagrams encoding the topologically distinct localized and delocalized phases of noninteracting fermionic quasiparticles for any symmetry class from the tenfold way in one, two, and three dimensions.
