Defining Reconciliation Studies: Theoretical and Practical Dimensions

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT Reconciliation studies (RS) has become increasingly influential in understanding alternative views to ending conflict and dealing with the aftermath. As a discipline or field, however, it is not well defined. The actual usefulness of reconciliation (as a concept), or of RS (as a discipline), is debated, and due to its growing usage, it is ...

Coherence‐Gated Mirau Interferometry for Single‐Shot Quantitative Phase Imaging and Motion Sensing

open access: yesLaser &Photonics Reviews, EarlyView.
This paper presents a compact add‐on module converting a Mirau or other on‐axis interferometer into a single‐shot quantitative phase imaging system using coherence gating and precise optical path matching. Demonstrations include time‐resolved imaging of human cells and streaming red blood cells, visualization of evaporation dynamics in liquid mixtures,

Wigner function and coherence properties of cold and thermal neutrons [PDF]

open access: yes, 1999
We analyze the coherence properties of a cold or a thermal neutron by utilizing the Wigner quasidistribution function. We look in particular at a recent experiment performed by Badurek {\em et al.}, in which a polarized neutron crosses a magnetic field ...

The Welfare and Educational Impacts of Encounter Experiences and Displays on Zoo‐Housed Red Panda (Ailurus fulgens)

open access: yesZoo Biology, EarlyView.
We investigated the extent and composition of red panda (Ailurus Fulgens spp.) encounters amongst 150 global zoos and their impact on animal longevity and reproduction. Comparative data analysis suggests that encounter animals produced more offspring and had higher longevity (survival) than non‐encounter animals with differences noted between ...

Modifying the lifetime of an unstable system by an intense electromagnetic field [PDF]

open access: yes, 1999
We study the temporal behavior of a three-level system (such as an atom or a molecule), initially prepared in an excited state, bathed in a laser field tuned at the transition frequency of the other level. We analyze the dependence of the lifetime of the

On the structure of Finsler and areal spaces [PDF]

open access: yes, 2013
We study underlying geometric structures for integral variational functionals, depending on submanifolds of a given manifold. Applications include (first order) variational functionals of Finsler and areal geometries with integrand the Hilbert 1-form ...
