Uncle Traps: Harvesting Rewards in a Queue-based Ethereum Mining Pool
queue-based mining pools ethereum uncle blocks
2019/1/26
Mining pools in Proof-of-Work cryptocurrencies allow miners to pool their computational resources as a means of reducing payout variance. In Ethereum, uncle blocks are valid Proof-of-Work solutions wh...
Seasonal Fluctuation of Agriotes lineatus, A. obscurus and A. sputator Click Beetles Caught using Pheromone Traps in Poland
Agriotes spp. elaters forecasting monitoring Yatlorf traps IPM
2018/3/5
The trap catch of Agriotes species and dynamics of the occurrence of adult click beetles using pheromone traps were
determined, and the relationship between the dynamics of the caught wireworms and t...
Trapping of internal and external feeding stored grain beetle pests with two types of pitfall traps: a two-year field study
Coleoptera stored-product pests grain
2016/2/22
Pitfall trapping studies are available for particular stored grain pest species. In small farms, the stored grain pest control strategy is rarely species-specific but is often “pest ecological-group-s...
Effect of insecticide-treated trap logs and lure traps for Ips typographus (Coleoptera: Curculionidae) management on nontarget arthropods catching in Norway spruce stands
tripod trap logs pheromone trap
2015/5/5
The numbers of nontarget arthropods captured by Theysohn pheromone traps (TPTs) and insecticidetreated tripod trap logs (TRIPODs) were compared; both kinds of traps were baited with pheromone lures Ph...
Operational monitoring of the nun moth Lymantria monacha L. (Lepidoptera: Lymantriidae) using pheromone-baited traps – a rationalization proposal

The flight activities of adult sweetpotato whitefly, Bemisia tabaci, and leafhoppers were monitored by plastic cup traps at Boğalı, Taşçı, Hacıali, Doğankent and Bal...
Flight pattern of Archips podana (Lep.: Tortricidae) based on data from pheromone traps
Archips podana fruit tree tortrix moth apple orchards flight activity monitoring pheromone traps flight pattern degree-days
2015/1/30
In 9 years of the period 1993–1999 and 2001–2003 the flight activity of Archips podana was investigated by pheromone traps placed in four apple orchards in Central and East Bohemia. The cumulative cat...

Fundamental Limit to Atom-Ion Sympathetic Cooling in Paul Traps
Atom-Ion Sympathetic Paul Traps Atomic Physics
2012/5/12
We present a fundamental limit to the sympathetic cooling of ions in radio-frequency traps using cold atoms. The limit arises from the work done by the trap electric field during a long-range ion-atom...
