A new approach based on relativistic kinetic equations is proposed to solve the long-standing puzzle of light cluster formation, also called nucleosynthesis, in high-energy heavy-ion collisions. This method addresses the tension between STAR data and previous studies relying on either statistical equilibrium or coalescence approaches.

Time-series discord is widely used in data mining applications to characterize anomalous subsequences in time series. Compared to some other discord search algorithms, the direct search algorithm based on the recurrence plot shows the advantage of being fast and parameter free. The direct search algorithm, however, relies on quasi-periodicity in input time series, an assumption that limits the algorithm＇s applicability. In this paper, we eliminate the periodicity assumption from the direct search algorithm by proposing a reference function for subsequences and a new sampling strategy based on the reference function. These measures result in a new algorithm with improved efficiency and robustness, as evidenced by our empirical evaluation.

The management of gastric cancer continues to evolve. Whilst surgery alone is effective when tumours present early,a large proportion of patients are diagnosed with loco-regionally advanced disease,resulting in high locoregional and distant relapse rates,with subsequent poor survival. Early attempts at improving outcomes following resection were disappointing;however,randomized trials have now established either post-operative chemoradiotherapy(INT0116) or peri-operative chemotherapy as standard adjuvant therapies in the Western world. There remain,however,significant differences in the approach to management between the West and East. In Asia,where there is the highest incidence of gastric cancer,extended resection followed by adjuvant chemotherapy represents the standard of care. This review discusses current standard adjuvant therapy in gastric adenocarcinoma,as well as recent and ongoing trials investigating novel(neo)adjuvant approaches,which hope to build on the successes of previous studies.
