Progress on Continental Scientific Drilling Project of Cretaceous Songliao Basin (SK-1 and SK-2)

The Lake El’gygytgyn Scientific Drilling Project – Conquering Arctic Challenges through Continental Drilling

Between October 2008 and May 2009, the International Continental Scientific Drilling Program (ICDP) co-sponsored a campaign at Lake El ́gygytgyn, located in a 3.6-Ma-old meteorite impact crater in northeastern Siberia. Drilling targets included three holes in the center of the 170-m-deep lake, utilizing the lake ice cover as a drilling platform, plus one hole close to the shore in the western la...

Neurospora spore killers Sk-2 and Sk-3 suppress meiotic silencing by unpaired DNA.

In Neurospora crassa, pairing of homologous DNA segments is monitored during meiotic prophase I. Any genes not paired with a homolog, as well as any paired homologs of that gene, are silenced during the sexual phase by a mechanism known as meiotic silencing by unpaired DNA (MSUD). Two genes required for MSUD have been described previously: sad-1 (suppressor of ascus dominance), encoding an RNA-...

Title : Increasing SK 2 Channel Activity Impairs

29 Enhanced intrinsic neuronal excitability of hippocampal pyramidal neurons via 30 reductions in the postburst afterhyperpolarization (AHP) has been hypothesized to be a 31 biomarker of successful learning. This is supported by considerable evidence that 32 pharmacological enhancement of neuronal excitability facilitates learning. However, it 33 has yet to be demonstrated that pharmacological ...

On the Overlap in the Multiple Spherical Sk Models 1

In order to study certain questions concerning the distribution of the overlap in Sherrington–Kirkpatrick type models, such as the chaos and ultrametricity problems, it seems natural to study the free energy of multiple systems with constrained overlaps. One can write analogues of Guerra's replica symmetry breaking bound for such systems but it is not at all obvious how to choose informative fu...
