Analysis of the Icelandic Oral Hymn Tradition as Seen in the Twentieth-century Enthnographic Recordings of Stridsmenn Krist ( Christ Bears His Cross )
The Hymns of the passion are a collection of Icelandic poems (1656-1659) that have been important to Icelandic religious life since the seventeenth century. Until an organ was first brought to Iceland in 1840, hymns were unaccompanied both in church and in the home. Though the words of the hymns were reprinted several times, the musical notation seldom accompanied them, allowing for a strong oral tradition to form. I transcribed 31 field recordings of the hymn Stridsmenn Krist ( Christ bears his cross ). I then compared these transcriptions in order to identify rhythmic and melodic variations. The final stage of my research is grouping similar variants to determine possible trends in oral tradition with respect to age or geographic region
Techniques for the Synthesis of Reversible Toffoli Networks
This paper presents novel techniques for the synthesis of reversible networks
of Toffoli gates, as well as improvements to previous methods. Gate count and
technology oriented cost metrics are used. Our synthesis techniques are
independent of the cost metrics. Two new iterative synthesis procedure
employing Reed-Muller spectra are introduced and shown to complement earlier
synthesis approaches. The template simplification suggested in earlier work is
enhanced through introduction of a faster and more efficient template
application algorithm, updated (shorter) classification of the templates, and
presentation of the new templates of sizes 7 and 9. A novel ``resynthesis''
approach is introduced wherein a sequence of gates is chosen from a network,
and the reversible specification it realizes is resynthesized as an independent
problem in hopes of reducing the network cost. Empirical results are presented
to show that the methods are effective both in terms of the realization of all
3x3 reversible functions and larger reversible benchmark specifications.Comment: 20 pages, 5 figure
The planetary data system educational CD-ROM
The Planetary Data System (PDS) is producing a special educational CD-ROM that contains samples of PDS datasets and is expected to be released in 1993. The CD-ROM will provide university-level instructors with PDS-compatible materials and information that can be used to construct student problem sets using real datasets. The main purposes of the CD-ROM are to facilitate wide use of planetary data and to introduce a large community to the PDS. To meet these objectives the Educational CD-ROM will also contain software to manipulate the data, background discussions about scientific questions that can be addressed with the data, and a suite of exercises that illustrate analysis techniques. Students will also be introduced to the SPICE concept, which is a new way of maintaining geometry and instrument information. The exercises will be presented at the freshman through graduate student levels. With simplification, some of the material should also be of use at the high school level
Population-level evidence of survival benefits of patient-reported outcome symptom monitoring software systems in routine cancer care
Symptom management is a cornerstone of quality oncology care. Most patients with cancer experience debilitating symptoms related to the disease itself or to treatment toxicities. If symptoms are not detected early enough, they can worsen and lead to unnecessary suffering, avoidable hospital services, and even death. Numerous prior studies have shown that up to half of patients' symptoms go undetected by their care teams. There is therefore a substantial opportunity to improve symptom detection and early interventions to avoid downstream complications and improve outcomes
Strong Secrecy for Multiple Access Channels
We show strongly secret achievable rate regions for two different wiretap
multiple-access channel coding problems. In the first problem, each encoder has
a private message and both together have a common message to transmit. The
encoders have entropy-limited access to common randomness. If no common
randomness is available, then the achievable region derived here does not allow
for the secret transmission of a common message. The second coding problem
assumes that the encoders do not have a common message nor access to common
randomness. However, they may have a conferencing link over which they may
iteratively exchange rate-limited information. This can be used to form a
common message and common randomness to reduce the second coding problem to the
first one. We give the example of a channel where the achievable region equals
zero without conferencing or common randomness and where conferencing
establishes the possibility of secret message transmission. Both coding
problems describe practically relevant networks which need to be secured
against eavesdropping attacks.Comment: 55 page
Improving Benefit-harm Assessment of Therapies from the Patient Perspective: OMERACT Premeeting Toward Consensus on Core Sets for Randomized Controlled Trials
Objective: Outcome Measures in Rheumatology (OMERACT) convened a premeeting in 2018 to bring together patients, regulators, researchers, clinicians, and consumers to build upon previous OMERACT drug safety work, with patients fully engaged throughout all phases.
Methods: Day 1 included a brief introduction to the history of OMERACT and methodology, and an overview of current efforts within and outside OMERACT to identify patient-reported medication safety concerns. On Day 2, two working groups presented results; after each, breakout groups were assembled to discuss findings.
Results: Five themes pertaining to drug safety measurement emerged.
Conclusion: Current approaches have failed to include data from the patient’s perspective. A better understanding of how individuals with rheumatic diseases view potential benefits and harms of therapies is essential
