This article considers an analogous problem in which the observed random variables are the steps of a symmetric random walk. Assuming continuously distributed step sizes, it describes the optimal stopping rules for the cases n = 2 and n = 3 in two versions of the problem: a "full information" version in which the actual steps of the random walk are disclosed to the decision maker; and a "partial information" version in which only the relative ranks of the positions taken by the random walk are observed. When n = 3, the optimal rule and expected rank depend on the distribution of the step sizes. The authors give sharp bounds for the optimal expected rank in the partial information version, and fairly sharp bounds in the full information version.

This article presents results of molybdenum disulfide monolayer (MoS₂) growth by strategically placing water droplets on the growth substrate and/or in the source prior to its loading in the growth chamber.

This article reports the preparation and characterisation of the simple dppn complex,[Fe2(CO)4(κ2-dppn)(µ-edt)], together with an investigation of its proton-reduction ability.

This article uses molecular dynamics simulations and experimental point mutations to probe the role of S-loop residues in tertiary structure, substrate binding, and allosteric communication.

This article describes the construction of a novel luminescent azo-linked polymer from 1,3,6,8-tetra(4--aminophenyl)pyrene using a copper(I)-catalyzed oxidative homocoupling reaction.

This article contains a systematic investigation of the nature of the nontrivial interface states in topological/normal insulator (TI/NI) heterostructures.

This article proposes that the integration of these signals is mediated through pulses of gene expression that are coordinated through out the plant in a systemic manner by the ROS/Ca⁺² waves.

The article shows how a recently-introduced method from algebraic topology, namely proximal planar vortex 1-cycles, might be helpful in detecting hidden features of the shapes and holes in images, therefore contributing to the solution of both cold and fresh forensic cases. They apply this technique in a recent case, Aldo Moro's death.
