1) The paper proposes a co-ranking framework to adapt graph-based ranking to tweet recommendation by simultaneously ranking tweets and their authors.
2) The co-ranking algorithm considers popularity, personalization based on user interests, and diversity to avoid closely connected nodes having only high scores.
3) An evaluation on a large Twitter dataset from 2011 shows the co-ranking approach improves tweet recommendation over baselines by 18.3% in DCG and 7.8% in MAP.

The document discusses the history and structures of benzene. In the 19th century, scientists proposed various structures for benzene including those suggested by Ladenburg, Dewar, benzvalene, and 3,3'-bicyclopropenyl. However, problems were identified with the structure proposed by Kekulé in 1861 which depicted benzene as alternating single and double bonds between the carbon atoms. The key aromatic structural features of benzene that were later established include the connectivity of adjacent 2p orbitals in a fully conjugated system that results in the molecule being almost flat.
Stereo-preference in the degradation of the erythro and threo isomers of b-O-4-type lignin model compounds in oxidation processes Ⅲ: in the reaction with chlorine- and manganese-based oxidants
This document summarizes a review on active oxygen and its applications. It discusses the generation and physiological roles of active oxygen species in organisms, including their involvement in biochemical reactions and defense systems. It also outlines various practical applications of active oxygen species in medical treatment, material development, and environmental purification. Specific examples provided include the use of singlet oxygen in photodynamic cancer therapy, synthesis of functional materials, degradation of polymers and endocrine disruptors. Methods for generating and detecting singlet oxygen are also summarized.
1. A new copper-containing catalyst based on a hemicryptophane complex was developed for the oxidation of cycloalkanes using hydrogen peroxide.
2. The hemicryptophane complex provided increased stability over model complexes and prevented degradation, leading to higher reaction yields.
3. Testing on cyclohexane, cyclooctane, and cyclodecane substrates showed the hemicryptophane complex could better discriminate between substrates similarly to natural enzymes, selectively oxidizing cyclohexane over the larger cycloalkanes.
This document provides a summary of computational organic chemistry methods for investigating molecular structures, properties, reactivities, and selectivities. It describes the basic concepts of molecular mechanics and quantum chemistry methods, including their advantages and limitations. Applications include determining molecular geometries and conformations, absolute configurations, electron distributions, acidities, and frontier molecular orbital energies to examine reactivity and selectivity. Combining computational methods with experiments allows more reliable investigations.
