U.S. Plant Variety Protection: Sound And Fury...?, Mark D. Janis, Jay P. Kesan

Articles by Maurer Faculty

This Article offers a critical reassessment of U.S. approaches to intellectual property protection for plant innovation. Three developments make this reassessment timely. First, the Supreme Court has finally confirmed that utility patent claims to plants and seeds satisfy the 35 U.S.C. Section 101 subject matter eligibility requirement. Plant innovation in the United States is now subject to utility patent protection, as well as concurrent protection under the Plant Variety Protection Act (PVPA). However, little work has been done to explain the role of PVPA protection in a system of concurrent protection, or to develop a coherent policy vision within which …

Broad Are Nebraska's Rolling Plains: The Early Writings Of George Bird Grinnell, Richard Vaughan

Articles by Maurer Faculty

Profiles the life of writer George Bird Grinnell (1849-1938) and the influence his first trip to Nebraska had in shaping his early writings about the American West. Among the works he published were several groundbreaking books about the Plains Indians of the late 19th and early 20th centuries. Not only did this 1870 trip to Nebraska, as a member of O. C. Marsh’s first Yale Paleontological Expedition, influence Grinnell's scholarly endeavors, but his deep interest in the state also influenced his lifelong devotion to environmental preservation and established him as an important advocate for the protection and welfare of Native …

Variations On The Virgin: Anne De Marquets’S Depiction Of Mary In The Sonets Spirituels, Russell J. Ganim

Department of Modern Languages and Literatures: Faculty Publications

This paper explores the manner in which Anne de Marquets’s (1533– 1588) Sonets Spirituels (published posthumously in 1605) reshapes conventional portraits of the Virgin Mary. A Dominican nun at the Royal Priory in Poissy, Marquets, like many Baroque Catholic poets, follows Church tradition in glorifying Mary as a maternal symbol of chastity and faith. Yet, unlike Gabrielle de Coignard (OEuvres chrestiennes, 1594), Jean de La Ceppède (Théorèmes, 1613, 1622), or other of her lyric peers, Marquets depicts the Virgin as a subjective, intellectual near-deity whose role occasionally borders on the messianic. The basic approach of this …

Concordant Paleolatitudes For Neoproterozoic Ophiolitic Rocks Of The Trinity Complex, Klamath Mountains, California, Edward A. Mankinen, Nancy Lindsley-Griffin, John R. Griffin

Department of Earth and Atmospheric Sciences: Faculty Publications

New paleomagnetic results from the eastern Klamath Mountains of northern California show that Neoproterozoic rocks of the Trinity ophiolitic complex and overlying Middle Devonian volcanic rocks are latitudinally concordant with cratonal North America. Combining paleomagnetic data with regional geologic and faunal evidence suggests that the Trinity Complex and related terranes of the eastern Klamath plate were linked in some fashion to the North American craton throughout that time, but that distance between them may have varied considerably. A possible model that is consistent with our paleomagnetic results and the geologic evidence is that the Trinity Complex formed and migrated parallel …

Governance Within The Navajo Nation: Have Democratic Traditions Taken Hold?, David E. Wilkins

Jepson School of Leadership Studies articles, book chapters and other publications

This essay crafts a description and analysis of the political and institutional context, structures, and issues of the Navajo Nation's government. We begin with a demographic, institutional, and ideological assessment of the nation as its currently stands, move to a historical overview of the nation from precontact times to the 1989 riots and conclude with a short policy portfolio of three issues—land claims, gaming, and taxation—that will likely impact the shape and direction the nation will head into the twenty-first century.

Esther Not Judith: Why One Made It And The Other Didn’T, Sidnie White Crawford

Department of Classics and Religious Studies: Faculty Publications

Brave, wise, and stunningly beautiful, Esther and Judith have much in common. Both Jewish heroines live under foreign domination. Both risk their lives to save their people from oppression. One of the few differences between the two women is that Judith is openly pious and Esther is not. Indeed, God is not even mentioned in the Hebrew version of the Book of Esther. So why was the story of Esther included in the Hebrew Bible while the Book of Judith was left out? Because Esther never threatened the status quo, but Judith was a dangerous woman who had the power …

A Set Of New Sea Ice Feature Descriptors For Sar Images, Leen-Kiat Soh

School of Computing: Technical Reports

In this paper, we present a set of algorithms for describing sea ice features in SAR images. These algorithms we have implemented and incorporated in the ARKTOS software package, an intelligent sea ice classification. These algorithms have unique characteristics. Some are extensions or adaptations of existing image processing techniques to the specific problem domain of satellite sea ice classification, while some are innovative designs, inspired by the aforementioned problem domain. These feature descriptors may be generalized to other remote sensing applications.

Two Algorithms For Shaped-Based Porosity Measures, Leen-Kiat Soh

School of Computing: Technical Reports

In this paper, we present two algorithms for shape-based porosity measures. Specifically, we describe two innovative attributes called perimeter porosity and area porosity as feature descriptors. Perimeter porosity refers to how “porous” or “weak” an image object is, while area porosity determines the degree of “branchiness” of an object. We show the applicability of the two measures through a SAR sea ice image classification example.

“Married Widowhood”: Maintaining Couplehood When One Spouse Is Living In A Nursing Home, Dawn O. Braithwaite

Department of Communication Studies: Faculty Publications

When a marital partner moves to a nursing home, how do community-dwelling spouses, labeled “married widows,” adapt and cope with changes in the relationship and their own marital roles? The first goal of this study was to explore the role additions and deletions for community-based wives whose husbands moved to a nursing home. The second goal was to examine how these women discursively represent their own self-identity and the relationship they have with their husband who is living in a nursing home. Data were drawn from in-depth, face-to-face interviews with 21 wives whose husbands resided in a nursing home. A …

An Analytical Model For Virtual Topology Reconfiguration In Optical Networks And A Case Study, Xi Yang, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

An analytical model for Virtual Topology Reconfiguration (VTR) in optical networks is developed. It aims at the optical networks with a circuit-based data plane and an IPlike control plane. By identifying and analyzing the important factors impacting the network performance due to VTR operations on both planes, we can compare the benefits and penalties of different VTR algorithms and policies. The best VTR scenario can be adaptively chosen from a set of such algorithms and policies according to the real-time network situations. For this purpose, a cost model integrating all these factors is created to provide a comparison criterion independent …

Dynamic Routing In Translucent Wdm Optical Networks, Xi Yang, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Translucent WDM optical networks use sparse placement of regenerators to overcome the impairments and wavelength contention introduced by fully transparent networks, and achieve a performance close to fully opaque networks with much less cost. Our previous study proved the feasibility of translucent networks using sparse regeneration technique. We addressed the placement of regenerators based on static schemes allowing only fixed number of regenerators at fixed locations. This paper furthers the study by proposing a suite of dynamical routing schemes. Dynamic allocation, advertisement and discovery of regeneration resources are proposed to support sharing transmitters and receivers between regeneration and access functions. …

Dynamic Traffic Grooming Algorithms For Reconfigurable Sonet Over Wdm Networks, Shu Zhang, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

The emergence of Wavelength Division Multiplexing (WDM) technology provides the capability for increasing the bandwidth of Synchronous Optical Network (SONET) rings by grooming low-speed traffic streams onto different high-speed wavelength channels. Since the cost of SONET add-drop multiplexers (SADM) at each node dominates the total cost of these networks, how to assign the wavelength, groom in the traffic and bypass the traffic through the intermediate nodes has received a lot of attention from researchers recently.

A Novel Method To Improve The Test Efficiency Of Vlsi Tests, Hailong Cui, Sharad C. Seth, Shashank K. Mehta

School of Computing: Conference and Workshop Papers

This paper considers reducing the cost of test application by permuting test vectors to improve their defect coverage. Algorithms for test reordering are developed with the goal of minimizing the test cost. Best and worst case bounds are established for the performance of a reordered sequence compared to the original sequence of test application. SEMATECH test data and simulation results are used throughout to illustrate the ideas.

Automated Ontology Learning For A Semantic Web, Christopher N. Hammack, Qingfeng Lin, Hai Huang, Stephen Scott, Sharad C. Seth

School of Computing: Technical Reports

By expressing web page content in a format that machines can understand, the semantic web provides huge possibilities for the Internet and for machine reasoning. Unfortunately, there is a considerable distance between the present-day World Wide Web and the semantic web of the future. The process of annotating the Web to make it semantic web-ready is quite long and not without resistance. In this paper one mechanism for semanticizing the Web is presented. This system is known as AutoSHOE, and it is capable of categorizing pages according to one of the present HTML semantic representations (Simple HTML Ontology Extensions) by …

Centralized Vs. Distributed Connection Management Schemes Under Different Traffic Patterns In Wavelength-Convertible Optical Networks, Lu Shen, Byrav Ramamurthy

School of Computing: Conference and Workshop Papers

Centralized and Distributed methods are two connection management schemes in wavelength convertible optical networks. In the earlier work, the centralized scheme is said to have lower network blocking probability than the distributed one. Hence, much of the previous work in connection management has focused on the comparison of different algorithms in only distributed scheme or in only centralized scheme. However, we believe that the network blocking probability of these two connection management schemes depends, to a great extent, on the network traffic patterns and reservation times. Our simulation results reveal that the performance improvement (in terms of blocking probability) of …

Arctic Ocean Snow Melt Onset Dates Derived From Passive Microwave, A New Data Set, Mark R. Anderson, Sheldon D. Drobot

Department of Earth and Atmospheric Sciences: Faculty Publications

Snow melt onset is defined as the point in time when the appearance of liquid water in the snow pack changes the crystalline structure within the pack. Owing to the associated increase in surface albedo during melt, surface energy absorption increases rapidly after the onset of snow melt. Monitoring interannual variations in snow melt onset is therefore useful for accurately modeling surface conditions, and it is also valuable for validating climate models and detecting climate change. Since microwave emission changes rapidly when liquid water appears in the snow pack, passive microwave remote sensing techniques can monitor melt onset. Passive microwave …

Assessment Of Slip Severity Among Different Age Groups, Thurmon E. Lockhart, Jeffrey C. Woldstad, James L. Smith

Department of Industrial and Management Systems Engineering: Faculty Publications

A laboratory study utilizing new techniques for assessing slip severity was conducted to investigate the process of inadvertent slips and falls among different age groups. Forty-two subjects from three age groups (young adults, middle-aged, and the elderly) walked on a rectangular track at a self-determined pace. Without the subjects’ awareness, a slippery floor surface was placed on the track over a force-measuring platform. The results indicated that elderly adults’ friction demand (RCOF) was not significantly different from the young and middle-aged adults. The older adults, however, fell more often than the other age groups. Fall recovery threshold (FRT) measures indicated …

The Temporal Spectrum Of The Sdb Pulsating Star Hs 2201+2610 At 2 Ms Resolution, R Silvotti, T D. Oswalt, Nicole M. Silvestri, Glenn Carlson

Aerospace, Physics, and Space Science Faculty Publications

In this article we present the results of more than 180 hours of time-series photometry on the low gravity (log g = 5.4, Teff = 29 300 K, log He/H = -3.0 by number) sdB pulsating star HS 2201+2610, obtained between September 2000 and August 2001. The temporal spectrum is resolved and shows 5 close frequencies: three main signals at 2860.94, 2824.10 and 2880.69 μHz, with amplitudes of about 1%, 0.5% and 0.1% respectively, are detected from single run observations; two further peaks with very low amplitude (<0.07%) at 2738.01 and 2921.82 μHz are confirmed by phase analysis on several independent runs. Due to the small number of detected frequencies, it is not possible to obtain a univocal identification of the excited modes and perform a detailed seismological analysis of the star. No clear signatures of rotational splitting are seen. Nevertheless, the observed period spectrum is well inside the excited period window obtained from pulsation calculations with nonadiabatic models having effective temperature and surface gravity close to the spectroscopic estimates. Due to its relatively simple temporal spectrum, HS 2201+2610 is a very good candidate for trying to measure the secular variation of the pulsation periods in time. With this purpose a long-term monitoring of the star was started. The results of the first 11 months show amplitude variations up to ∼20% on time-scales of months, which are probably real, and allow us to measure the pulsation frequencies with an unprecedented 0.02 μHz resolution.

Asteroseismology Of Rxj 2117+3412, The Hottest Pulsating Pg 1159 Star, G Vauclair, Matt A. Wood

Aerospace, Physics, and Space Science Faculty Publications

The pulsating PG 1159 planetary nebula central star RXJ 2117+3412 has been observed over three successive seasons of a multisite photometric campaign. The asteroseismological analysis of the data, based on the 37 identified ℓ = 1 modes among the 48 independent pulsation frequencies detected in the power spectrum, leads to the derivation of the rotational splitting, the period spacing and the mode trapping cycle and amplitude, from which a number of fundamental parameters can be deduced. The average rotation period is 1.16 ± 0.05 days. The trend for the rotational splitting to decrease with increasing periods is incompatible with a …
