Compensatory mitigation is commonly used to replace aquatic natural resources being lost or degraded but little is known about the success of stream mitigation. This article presents a synthesis of information about 434 stream mitigation projects from 117 permits for surface mining in Appalachia. Data from annual monitoring reports indicate that the ratio of lengths of stream impacted to length...

[1] The relative impact of a large upstream dam versus in‐reach groundwater pumping on stream temperatures was analyzed for humid, semiarid, and arid conditions with long dry seasons to represent typical climate regions where large dams are present, such as the western United States or eastern Australia. Stream temperatures were simulated using the CE‐QUAL‐W2water quality model over a 110 kmmod...

We provide an attack to (EC)DSA digital signature built upon Coppersmith’s method. We prove that, if a, k are the private and ephemeral key, respectively, of the (EC)DSA scheme and (k−1mod q)a < 0.262 · q, then we can efficiently find a.
