New report highlights climate change effects on greater Yellowstone ecosystem：Greater Yellowstone area expected to become warmer, drier
climate change ecosystem warm and dry
2021/8/5
Temperature significantly increased and snowfall decreased in the iconic Greater Yellowstone Area since 1950 because of climate change, and these trends will likely continue through the rest of the ce...

his paper presents the complete description of the best differentials and linear hulls in 2-round Kuznyechik. We proved that 2-round MEDP=2−86.66...MEDP=2−86.66..., MELP=2−76.739...M...
Synchronous Byzantine Agreement with Expected $O(1)$ Rounds, Expected $O(n^2)$ Communication, and Optimal Resilience
Optimal Resilience authenticated setting
2018/11/2
We present new protocols for Byzantine agreement in the synchronous and authenticated setting, tolerating the optimal number of ff faults among n=2f+1n=2f+1 parties. Our protocols achieve an expected ...

data mining more than expected andean plateau
2017/9/5
Seismologists investigating how Earth forms new continental crust have compiled more than 20 years of seismic data from a wide swath of South America’s Andean Plateau and determined that processes the...
Improved upper bounds for the expected circuit complexity of dense systems of linear equations over GF(2)
Gate complexity linear systems dense matrices
2017/3/6
Minimizing the Boolean circuit implementation of a given cryptographic function is an important issue. A number of papers [12,13,11,5] only consider cancellation-free straight-line programs for produc...
