A new BICM-ID technique that makes efficient use of a mixture of standard Gray and anti-Gray extended mapping, combined with irregular degree-allocated repetition code with check nodes. It is shown that with the proposed technique, very low rate codes that can achieve turbo cliff at a very low Es/N0 value range can well be designed, and that the EXIT chart analysis and chain simulation results ...

The activity cliff concept has experienced increasing interest in medicinal chemistry and chemoinformatics. Activity cliffs have originally been defined as pairs of structurally similar compounds that are active against the same target but have a large difference in potency. Activity cliffs are relevant for structure-activity relationship (SAR) analysis and compound optimization because small c...

In a poem titled “Fence or Ambulance” written more than one hundred years ago, Joseph Malins described the policy dilemma a city faced in tackling the rising morbidity and mortality from accidental falls from a dangerous cliff. The 2 policy options considered included building a strong fence around the edge of the cliff or raising funds to support an ambulance down in the valley. The city initi...

Future planetary exploration missions will use cooperative robots to explore and sample rough terrain. To succeed robots will need to cooperatively acquire and share data. Here a cooperative multi-agent sensing architecture is presented and applied to the mapping of a cliff surface. This algorithm efficiently repositions the systems’ sensing agents using an information theoretic approach and fu...

Recent evidence that water flowed down the faces of some Martian cliffs has created an interest in the scientific community to explore these cliffs more thoroughly, perhaps using robots. This paper presents a technique for autonomous exploration that considers multiple forms of information while exploring. The method is applied to the problem of autonomously exploring cliffs. The exploring robo...

An extended Hubbard model on a two-leg ladder is numerically studied by means of the quantum Monte Carlo techniques. The model we study has the nearest-neighbor interactions which are repulsive along chains and attractive for rungs. The plots of the doping parameter versus the chemical potential show two cliff-like regions and a large plateau region. Results on the charge susceptibility suggest...

Arctic warming is leading to substantial changes to permafrost including rapid degradation of ice and ice-rich coasts and riverbanks. In this study, we present and evaluate a high spatiotemporal resolution three-year time series of X-Band microwave satellite data from the TerraSAR-X (TSX) satellite to quantify cliff-top erosion (CTE) of an ice-rich permafrost riverbank in the central Lena Delta...
