Statistical analysis of bulk nitrogen isotopes from IODP Site 323-U1342
No full textHere, we present the results of a statistical analysis published in Knudson et al., (2021, Science Advances), which investigates nitrogen isotopes from Integrated Ocean Drilling Program Expedition 323 Site U1342 in the Bering Sea, from 0-1.2 Ma. We analyzed the Site U1342 15Nbulk record from Knudson and Ravelo (2015, Geophysical Research Letters, https://doi.org/10.1002/2015GL066317). In Knudson et al. (2021), the bulk d15N record was detrended and Z-scores were calculated to determine statistically significant peaks. Z-scores were significantly higher during laminated intervals compared to non-laminated intervals (0.779 versus -0.112, P ≤0.0001). These data, in combination with high-resolution paleo-productivity indicators at the same site, provide evidence for enhanced nitrate utilization during laminated intervals compared with non-laminated intervals
Letter from Laura Page Knudsen for Representative Burdick to J. K. Murray Regarding Three Affiliated Tribes Enrollment of Children, September 14, 1956
No full textThis letter, dated September 14, 1956, from Laura Page Knudson on behalf of United States (US) Representative Usher Burdick to J. K. Murray responds to Murray\u27s appeal for assistance in getting children enrolled with the Three Affiliated Tribes as the Tribal Business Council has been rejecting all applicants submitting after July 1, 1956. Knudson informs Murray that they are taking the issue up with Commissioner Glenn Emmons and will get back to him.

Enhancement of K+ conductance improves in vitro the contraction force of skeletal muscle in hypokalemic periodic paralysis
No full textAn abnormal ratio between Na+ and K+ conductances seems to be the cause for the depolarization and paralysis of skeletal muscle in primary hypokalemic periodic paralysis. Recently we have shown that the k+ channel opener cromakalim hyperpolarizes mammalian skeletal muscle fibers. Now we have studied the effects of this drug on the twitch force of muscle biopsies from normal and diseased human skeletal muscle. Cromakalim had little effect on the twitch force of normal muscle whereas it strongly improved the contraction force of fibers from patients suffering from hypokalemic periodic paralysis. Recordings of intracellular K+ and Cl- activities in human muscle and isolated rat soleus muscle support the view that cromakalim enhances the membrane K+ conductance (gK+). These data indicate that K+ channel openers may have a beneficial effect in primary hypokalemic periodic paralysis
High resolution XRF from IODP Site 323-U1342
No full textWe present new high resolution records of elemental ratios from Integrated Ocean Drilling Program Expedition 323 Site U1342 in the Bering Sea. Sediment cores measured by non-disruptive XRF with the TATSCAN-F2 at the Japan Agency for Marine-Earth Technology in 2009. Si/Ti, Fe/Ti, and Fe/S ratios were calculated based on the mass measurements (at 0.50 cm resolution) of each of these elements. XRF measurements are likely not greatly affected by water attenuation, since precautions were taken to scan IODP cores after they had been opened and were no longer damp. Core tops (including the B/A laminated interval at this site) may be an exception for XRF reliability, as they are relatively soft and have greatest porosity and water content. In Knudson et al. (2021, Science Advances), Fe/Ti ratios were used to look at a possible change in iron source, and Si/Ti ratios were used as a proxy for biogenic opal deposition. This instrument, analytical methods, precision, and accuracy are described in detail in Sakamoto et al., 2006: T. Sakamoto, K. Kuroki, T. Sugawara, K. Aoike, K. Iijima, S. Sugisaki, Non-destructive X-ray fluorescence (XRF) core-imaging scanner, TATSCAN-F2. Sci. Drill 2, 37-39 (2006)

Weight percent nitrogen from Bering Sea IODP Site 323-U1342
No full textHere, we present a high-resolution paleo-productivity record of weight percent nitrogen (wt % N) from IODP Expedition 323 Site U1342 (818 m depth) in the Bering Sea from 0-1.2 Ma. Sediment cores were sampled at ~3 cm intervals with in massive sediments and 1 cm intervals within laminated sediments, yielding an average sampling frequency of ~1 sample/kyr. Unwashed sediment samples were freeze-dried and crushed using a mortar and pestle. Bulk sediments (unacidified) were analyzed for weight percent total nitrogen (wt % N) on a Carlo Erba 1108 elemental analyzer, interfaced to a Thermo Finnigan Delta Plus XP IRMS, at the University of California, Santa Cruz. Low correlation between nitrate utilization proxy presented in this study (Knudson et al., 2016, Geophysical Research Letters, doi:10.1002/2015GL066317) and paleo-productivity proxies, including wt% N, provide evidence that fluctuations in primary productivity were not the main control over nitrate utilization at Site U1342 over the past 1.2 Myrs. Together, these results imply that enhanced physical water column stratification was likely the most important mechanism controlling nitrate utilization on orbital (glacial-interglacial) timescales
Case study using the Oregon StateWide Integrated Model for the Oregon freight plan
No full textThe Oregon Department of Transportation (ODOT) recently completed its first statewide long-range Freight Plan. Given the uncertainty of future economic conditions, the second generation Oregon StateWide Integrated Model (SWIM2) was used to evaluate the implications of uncertain economic conditions to long range freight planning. Several lessons learned from past analyses prompted changes to the analysis process followed for this particular project. The Oregon Freight Plan analysis enabled us to identify ways modeling services can be more effective in supporting long range planning. While having sophisticated tools to conduct the analysis is important, other aspects of the planning analysis process appear to be just as important, in some cases perhaps even more important than the tools themselves. This paper aims to share some of the strategies Oregon has identified as key to providing effective modeling services to our planning peers.Becky Knudson, John Douglas Hunt, Tara Weidner, Alex Bettinardi, Erin Wardell.Title from PDF title page (viewed on November 22, 2022)."Prepared for the 2011 TRB Transportation Planning Applications Conference May 2011."This archived document is maintained by the State Library of Oregon as part of the Oregon Documents Depository Program.

On the K-Theory of Elliptic Curves
No full text. Let A be the coordinate ring of an affine elliptic curve (over an infinite field k) of the form X \Gamma fpg, where X is projective and p is a closed point on X. Denote by F the function field of X. We show that the image of H ffl (GL2 (A); Z) in H ffl (GL2 (F ); Z) coincides with the image of H ffl (GL2 (k); Z). As a consequence, we obtain numerous results about the K-theory of A and X. For example, if k is a number field, we show that r2(K2(A)\Omega Q) = 0, where rm denotes the mth level of the rank filtration. 1. Introduction Computing the K-theory of a scheme X is a very difficult task. Even the simplest case X = Spec k, where k is a field, is not completely solved, although a great deal is known. The next case to consider is when X is a curve over k, and it is here that the complexity grows rapidly. Some curves of genus zero present no real difficulty thanks to the fundamental theorem: K i (R[t; t \Gamma1 ]) = K i (R) \Phi K i\Gamma1 (R) for R regular. The K-theory of elli..
