On 27 May 2015, the scientific study by Albert et al. (1) entitled “Supplementation with a blend of krill and salmon oil is associated with increased metabolic risk in overweight men” was published on...
Challenging the empirical mean and empirical variance: a deviation study
Non-parametric estimation M-estimators PAC-Bayes bounds
2010/12/3
We present new M-estimators of the mean and variance of real valued random variables, based on PAC-Bayes bounds. We analyze the non-asymptotic minimax properties of the deviations of those estimators ...

Canada and Mexico are formally challenging US country of origin (COOL) legislation at
the World Trade Organization. The industries most affected by COOL are beef and pork.
The effect of COOL on No...
Valuable mineral resources are widely distributed throughout the seabed. autonomous underwater vehicles (AUVs) are preferable to remotely-operated vehicles (ROVs) when probing for such mineral resources as the extensive exploration area makes it difficult to maintain contact with operators. AUVs depend on batteries, so their power consumption should be reduced to extend exploration time. Power for conventional marine instrument systems is incorporated in their waterproof sealing. External intermittent control of this power source until termination of exploration is challenging due to limitations imposed by the underwater environment. Thus, the AUV must have a power control system that can improve performance and maximize use of battery capacity. The authors developed such a power control system with a three-step algorithm. It automatically detects underwater operational states and can limit power, effectively decreasing power consumption by about 15%.
