Intrinsic Value: Towards A Pragmatic Theory

Intrinsic value is a concept central to the environmentalist movement. Whether one believes that natural objects have intrinsic value is supposed to determine whether one takes a ecocentric or homocentric approach to environmentalism, whether we practice deep or (merely) shallow ecology.  Yet this concept is also a center of controversy and confusion.  Just what does it mean for something to ha...

Towards a realistic axion star

In this work we estimate the radius and the mass of a self-gravitating system made of axions. The quantum axion field satisfies the Klein-Gordon equation in a curved space-time and the metric components of this space-time are solutions to the Einstein equations with a source term given by the vacuum expectation value of the energy-momentum operator constructed from the axion field. As a first s...

Towards a realistic echographic simulator

Echography is a useful tool to diagnose a thrombosis; however, since it is difficult to learn to perform this procedure, the objective of this work is to create a simulation to allow students to practice in a virtual environment. Firstly, a physical model of the thigh was constructed based on experimental data obtained using a force sensor mounted on a robotic arm. We present a spring damper mo...

f̄ f WITH REALISTIC CUTS

We derive compact analytical formulae of the Bonneau-Martin type for the reaction e + e − → ¯ f f γ with cuts on minimal energy and acollinearity of the fermions, where the photons may be emitted both from the initial or final states. Soft-photon exponentiation is also taken into account. One of the cleanest scattering processes at elementary particle accelerators is fermion-pair production in ...

Towards More Realistic ANTS

In this paper, we summarize our results on a variant of the Ants Nearby Treasure Search (ANTS) problem, where n mobile agents, controlled by asynchronous randomized finite automata, search collaboratively for a treasure hidden by an adversary. We show that despite these restrictions, the treasure can be located in an optimal run-time of O(D + D2/n). Moreover, we consider slight variations of th...
