The three classes of enzymes which inactivate aminoglycosides and lead to bacterial resistance
are reviewed. DNA hybridization studies have shown that different genes can encode …

The Late Wisconsinan advance of the Laurentide Ice Sheet started from a Middle Wisconsinan
interstadial minimum 27–30 14 C ka BP when the ice margin approximately followed the …

The spatio-temporal pattern of peak Holocene warmth (Holocene thermal maximum, HTM)
is traced over 140 sites across the Western Hemisphere of the Arctic (0–180W; north of ∼60N…

Presented in this work is a nonlinear adaptive nonreflecting boundary condition (NRBC) that,
when compared with classical local NRBCs, further reduces the wave reflection error at far …

In the future, Arctic warming and the melting of polar glaciers will be considerable, but the
magnitude of both is uncertain. We used a global climate model, a dynamic ice sheet model, …

The temperature history of the first millennium CE is sparsely documented, especially in the
Arctic. We present a synthesis of decadally resolved proxy temperature records from …

Northern Hemisphere summer temperatures over the past 8000 years have been paced by
the slow decrease in summer insolation resulting from the precession of the equinoxes. …

Sea-level rise from melting of polar ice sheets is one of the largest potential threats of future
climate change. Polar warming by the year 2100 may reach levels similar to those of …

The contribution of seven known and nine predicted genes or operons associated with multidrug
resistance to the susceptibility of Escherichia coli W3110 was assessed for 20 different …

A new method is presented for the explicit Eulerian finite difference computation of shock
capturing problems involving multiple resolved material phases in three dimensions. We solve …
