Alkoxysulfonium Salts Unlock Access to New Aryl Sulfonium Salts for Cross‐Coupling
Angewandte Chemie, EarlyView.Hard‐to‐access (hetero)aryl sulfonium salts are prepared using stable methoxysulfonium salts in combination with the magnesiation of (hetero)aryl bromides. The approach allows access to aryl sulfonium salts bearing electron‐deficient (hetero)aryl rings, or electron‐rich aryl motifs in which the sulfonium motif resides at an alternative position on the ...

Revealing flows in the local economy through visualisations:customers, clicks/cliques and clusters [PDF]
It is well known by now, that the world has suffered an economic downturn. This has led many governments and organisations to invest resources into researching varying strategies to combat such problem.

Enabling Stochastic Dynamic Games for Robotic Swarms
Advanced Intelligent Systems, EarlyView.This paper scales stochastic dynamic games to large swarms of robots through selective agent modeling and variable partial belief space planning. We formulate these games using a belief space variant of iterative Linear Quadratic Gaussian (iLQG). We scale to teams of 50 agents through selective modeling based on the estimated influence of agents ...

Angewandte Chemie, EarlyView.Gas‐phase complexation of chiral methyloxirane by achiral phenol results in induced chiroptical response of phenol. Two pseudo enantiomer complexes are observed, corresponding to hydrogen bonding from phenol to either of the lone electron pair of the methyloxirane oxygen, denoted as Pro R and Pro S, with opposite chiral deformation of phenol and ...

Utility-based barter trade incentive scheme in opportunistic network
Tongxin xuebao, 2016 In opportunistic networks,existing simple barter trade (SBT) incentive scheme degraded the network performance due to the blindly caching strategy.So a utility-based barter trade (UBT) incentive mechanism was proposed.In the UBT scheme,nodes cache ...

The Barter Method: A New Heuristic for Global Optimization and its Comparison with the Particle Swarm and the Differential Evolution Methods [PDF]
The objective of this paper is to introduce a new population-based (stochastic) heuristic to search the global optimum of a (continuous) multi-modal function and to assess its performance (on a fairly large number of benchmark functions) vis-à-vis that ...

Worm‐Inspired Soft Robots With Modular Outfit‐Changing for Intelligent Multienvironment Adaptation
Advanced Intelligent Systems, EarlyView.This study proposes a worm‐inspired soft robot capable of locomotion across multiple environments through a modular “outfit‐changing” strategy. The robot integrates pneumatically actuated peristaltic segments with interchangeable external modules, enabling efficient motion on ground surfaces, within pipelines, through granular media, and underwater ...

Angewandte Chemie, EarlyView.Photocatalytic cross‐coupling: A redox‐neutral photochemical method enables direct C(sp2)─C(sp2) bond formation between phenols and heteroaryl halides using an organic dye and base. Complementary radical generation allows efficient cross‐coupling in up to 91% yield. Mechanistic studies, DFT, HTE, and machine learning rationalize and predict reactivity,

American Journal of Agricultural Economics, EarlyView.Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...
