Climate variability and simultaneous breadbasket yield shocks as observed in long-term yield records
Climate variability breadbasket yield shocks yield records
2024/4/1
That climate variability and change can potentially force multiple simultaneous breadbasket crop yield shocks has been established. But research quantifying the mechanisms behind such simultaneous sho...
The eerie sound of an extraterrestrial whirlwind has reached the Earth from more than 50 million miles away, thanks to the first working microphone to traverse the surface of Mars. The audio records t...
Fecal records show Maya population affected by climate change
Maya population climate change drought period wet period
2021/8/4
A new study has shown that the size of the Maya population in the lowland city of Itzan (in present-day Guatemala) varied over time in response to climate change. The findings show that both droughts ...

Weather radar drastic drop mayfly populations
2020/2/20
At the beginning of each summer, mayfly larvae emerge from bodies of water and shed their skin to become full-fledged mayflies, similar to the way in which caterpillars become butterflies.
The General Sieve Kernel and New Records in Lattice Reduction
cryptanalysis lattice reduction sieving
2019/1/29
We propose the General Sieve Kernel (G6K, pronounced /ʒe.si.ka/), an abstract stateful machine supporting a wide variety of lattice reduction strategies based on sieving algorithms. Using the bas...
New Bleichenbacher Records: Practical Fault Attacks on qDSA Signatures
Digital Signature Fault Attack Bleichenbacher's Nonce Attack
2018/5/2
In this paper, we optimize Bleichenbacher's statistical attack technique against (EC)DSA and other Schnorr-like signature schemes with biased or partially exposed nonces. Previous approaches to Bleich...
