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.

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 ...

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 ...

The postulates of gravitational thermodynamics [PDF]

, 1996
The general principles and logical structure of a thermodynamic formalism that incorporates strongly self-gravitating systems are presented. This framework generalizes and simplifies the formulation of thermodynamics developed by Callen.

Nonlinear Magnetohydrodynamics from Gravity [PDF]

, 2009
We apply the recently established connection between nonlinear fluid dynamics and AdS gravity to the case of the dyonic black brane in AdS_4. This yields the equations of fluid dynamics for a 2+1 dimensional charged fluid in a background magnetic field ...

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 Mean Field Platform for Excited State Quantum Chemistry [PDF]

, 2018
We present a mean field theory for excited states that is broadly analogous to ground state Hartree-Fock theory. Like Hartree-Fock, our approach is deterministic, state-specific, applies a variational principle to a minimally correlated ansatz, produces ...

Increase of Black Hole Entropy in Higher Curvature Gravity [PDF]

, 1995
We examine the Zeroth Law and the Second Law of black hole thermodynamics within the context of effective gravitational actions including higher curvature interactions.

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.
