Defining the upslope extent of Federal Clean Water Act jurisdiction over wetlands and streams has been contentious since passage but large effects on type, number, area that are protected by legislation. jurisdictional guidance in US changed evolved response to scientific knowledge, Supreme Court decisions, policy goals Presidential Administrations. In 2020, Trump administration replaced Obama ...

Understanding how natural variation in flow regimes influences stream ecosystem structure and function is critical to the development of effective management policies. Spatial among streams reasonably well understood for mesic regions, but a more robust characterization arid regions needed, especially support biological monitoring assessment programs. In this paper, we used long-term (41 years)...

Abstract In Menashe Streams managed aquifer recharge (MAR) site (Israel) desalinated seawater (DSW) is recharged since 2015, alongside ephemeral stream flows. This study quantifies the uncertainty of predictions mixing these two water sources in aquifer. Mixing estimations are based on significant difference content stable isotopes between sources. Uncertainties driven from heterogeneity and cl...

Bovine ephemeral fever is an acute and arthropod-borne viral disease of cattle and water buffalo which occurs seasonally in most of the world tropical and subtropical regions. The epizootic feature of the disease has been reported in Iran with serious economic consequences. The surface glycoprotein G of bovine ephemeral fever virus (BEFV) is composed of 4 antigenic sites (G1-G4) and plays the m...

In the desert of Abarkoh Basin, Central Iran, the influence of playa-lake level fluctuations on recent sedimentation mode of a terminal ephemeral fluvial-fan system and adjacent lacustrine/aeolian sediments of a playa fringe environment has been investigated. The surface geomorphology-sedimentology and its relationship with shallow subsurface sediments along a >25 km transect, has been studied....

We revisit document clustering in the context of the Web. Speci cally, we investigate on-line ephemeral clustering, whereby the input document set is generated dynamically, typically by search results, and the output clustering hierarchy has a short life span, and is used for interactive browsing purposes. Ephemeral clustering for interactive use introduces several new challenges. It requires a...

After a long period of spermatogenesis (several weeks to months), marine fish spermatozoa are delivered at male spawning in seawater (SW) at the same time as ova. In some fish species, as the ova micropyle closes quickly after release, these minute unicells, the spermatozoa, have to accomplish their task of reaching the micropyle within a very brief period (several seconds to minutes), for deli...

We show how any pair of authenticated users can on-the-fly agree on an elliptic curve group that is unique to their communication session, unpredictable to outside observers, and secure against known attacks. Our proposal is suitable for deployment on constrained devices such as smartphones, allowing them to efficiently generate ephemeral parameters that are unique to any single cryptographic a...
