Imaging of a weak target hidden behind a scattering medium can be significantly confounded by glare. We report a method, termed coherence gated negation (CGN), that uses destructive optical interference to suppress glare and allow improved imaging of a weak target. As a demonstration, we show that by permuting through a set range of amplitude and phase values for a reference beam interfering wi...

Results from agent-based or multi-agent simulation (AB/MAS) modelling can provide relevant information for policy makers, scientists and stakeholders about the boundary conditions of rural development and the uncertainties involved in land-use/cover change (LUCC). However, the process of model validation that can build trust in the outcomes for new parameter conditions and in future scenarios i...

Toxin-antitoxin (TA) loci are widespread in bacteria including important pathogenic species. Recent studies suggest that TA systems play a key role in persister formation. However, the persistence phenotype shows only weak dependence on the number of TA systems, i.e. they are functionally redundant. We use a mathematical model to investigate the interaction of multiple TA systems in the switchi...

Flow and Diffusion Distributed Structures (FDS) are stationary spatially periodic patterns that can be observed in reaction-diffusion-advection systems. These structures arise when the flow rate exceeds a certain bifurcation point provided that concentrations of interacting species at the inlet differ from steady state values and the concentrations are held constant. Normally, theoretical studi...

In spite of the several technical advantages of a freespace optical (FSO) communication, atmospheric turbulence can severely degrade the performance of a FSO link, because it creates random fluctuations in the phase and the amplitude of the received signal. The simultaneous usage of multiple transmit/receive apertures (MIMO) can mitigate the fading effects, that is particularly crucial for stro...

Quantum key distribution (QKD) and quantum communication enable the secure exchange of information between remote parties. Currently, the distributed-phase-reference (DPR) protocols, which are based on weak coherent pulses, are among the most practical solutions for long-range QKD. During the last 10 years, long-distance fiber-based DPR systems have been successfully demonstrated, although fund...

We compute the one-loop supersymmetric ~SUSY! contributions to the weak charges of the electron (QW e ), proton (QW p ), and cesium nucleus (QW ) in the minimal supersymmetric standard model ~MSSM!. Such contributions can generate several percent corrections to the corresponding standard model values. The magnitudes of the SUSY loop corrections to QW e and QW p are correlated over nearly all of...

There are a number of scenarios where users wishing to communicate, share a weak secret. Often, they are also part of a common social network. Connections (edges) from the social network are represented as shared link keys between participants (vertices). We propose mechanisms that utilise the graph topology of such a network, to increase the entropy of weak pre-shared secrets. Our proposal is ...
