Unbound states in C populated by -decay of the 16.11 MeV state
The reaction has been used to populate the state at an excitation energy of 16.11 MeV in C. -decay
to unbound states in C are identified from analysis of the decay of the
populated daughter states. Due to a new technique, -decay to the 10.8
MeV 1 state is observed for the first time, and transitions to the 9.64 MeV
(3) and 12.71 MeV (1) are confirmed. Unresolved transitions to natural
parity strength at 10 MeV and 11.5-13 MeV are also observed. For all
transitions partial widths are deducedComment: Corrected small typographical errors and added more details on data

Designing Long-Lasting Interior Products:Emotional Attachment, Product Positioning and Uniqueness
Major differences in rates of occupational accidents between different nationalities of seafarers
Objectives. Earlier studies and statistics have shown that merchant seafarers from the South
East Asia had considerable lower accident rates when compared with seafarers from
Western Europe. The purposes of the study were to investigate whether the earlier observations were sustained if further sources on occurrence of accidents were used and
to identify specific causes of excess accident rates among certain nationalities.
Methods. Occupational accidents aboard Danish merchant ships during one year were
identified from four different sources. These included accidents reported to the maritime
authorities, accidents reported to a mutual insurance company, files on medical costs
reimbursed by the government and finally, accidents in which there has been contact to
the radio medical service. Time at risk aboard was obtained from a register on all
employment periods aboard merchant ships.
Results. A total of 943 accidents causing personal injury to a seafarer directly caused by
work aboard were identified. Among these accidents, 499 had taken place aboard cargo
ships in international trade. Only these were used in the detailed analysis. The accident
rate for all identified accidents aboard cargo ships were 84 accidents per 1,000 years
aboard. The crude incidence rate ratio (IRR) for East European seafarers was 0.88 and
for South East Asians 0.38 using West European seafarers as reference. In a Poisson
regression analysis, the IRR for South East Asians was 0.29 (0.22-0.38). In an analysis
including only more serious accidents, IRR for South East Asians rose to 0.36 (0.26-
0.48).
Discussion. This study indicates that seafarers from South East Asia, mainly the Philippines,
may have a genuine lower risk of occupational accidents in comparison with seafarers
from Western and Eastern Europe. Differences in approach to safety and risk taking
between South East Asian and European seafarers should be identified and positives
attitudes included in accident preventing programmes.
Main messages. Seafarers from South East Asia, mainly the Philippines, seem to have a genuine
lower risk of occupational accidents in comparison with seafarers from Western and
Eastern Europe.
Policy implications. Differences in approach to safety and risk taking between South East Asian and
European seafarers should be identified and positives attitudes included in accident
preventing programmes
A Study on Optimization and Evaluation of the Visualization of Complex Algorithm Results in Remote Monitoring of COPD
BACKGROUND: Artificial intelligence (AI) can potentially increase the quality of telemonitoring in chronic obstructive pulmonary disease (COPD). However, the output from AI is often difficult for clinicians to understand due to the complexity. This challenge may be accommodated by visualizing the AI results, however it hasn't been studied how this could be done specifically, i.e., considering which visual elements to include.AIM: To investigate how complex results from a predictive algorithm for patients with COPD can be translated into easily understandable data for the clinicians.METHODS: Semi-structured interviews were conducted to explore clinicians' needs when visualizing the results of a predictive algorithm. This formed a basis for creating a prototype of an updated user interface. The user interface was evaluated using usability tests through the "Think aloud" method.RESULTS: The clinicians pointed out the need for visualization of exacerbation alerts and the development in patients' data. Furthermore, they wanted the system to provide more information about what caused exacerbation alerts. Elements such as color and icons were described as particularly useful. The usability of the prototype was primarily assessed as easily understandable and advantageous in connection to the functions of the predictive algorithm.CONCLUSION: Predictive algorithm use in telemonitoring of COPD can be optimized by clearly visualizing the algorithm's alerts, clarifying the reasons for algorithm output, and by providing a clear overview of the development in the patient's data. This can contribute to clarity when the clinicians should act and why they should act on alerts from predictive algorithms.</p
Contribution of Scalar Loops to the Three-Photon Decay of the Z
I corrected 3 mistakes from the first version: that were an omitted Feynman
integration in the function f^3_{ij}, a factor of 2 in front of log f^3_{ij} in
eq.2 and an overall factor of 2 in Fig.1 c). The final result is changed
drastically. Doing an expansion in the Higgs mass I show that the matrix
element is identically 0 in the order (MZ/MH)^2, which is due to gauge
invariance. Left with an amplitude of the order (MZ/MH)^4 the final result is
that the scalar contribution to this decay rate is several orders of magnitude
smaller than those of the W boson and fermions.Comment: 6 pages, plain Tex, 1 figure available under request via fax or mail,

Initial results from the Caltech/DRSI balloon-borne isotope experiment
The Caltech/DSRI balloonborne High Energy Isotope Spectrometer Telescope (HEIST) was flown successfully from Palestine, Texas on 14 May, 1984. The experiment was designed to measure cosmic ray isotopic abundances from neon through iron, with incident particle energies from approx. 1.5 to 2.2 GeV/nucleon depending on the element. During approximately 38 hours at float altitude, 100,000 events were recorded with Z or = 6 and incident energies approx. 1.5 GeV/nucleon. We present results from the ongoing data analysis associated with both the preflight Bevalac calibration and the flight data
Systematic trends in beta-delayed particle emitting nuclei: The case of beta-p-alpha emission from 21Mg
We have observed beta+-delayed alpha and p-alpha emission from the
proton-rich nucleus 21Mg produced at the ISOLDE facility at CERN. The
assignments were cross-checked with a time distribution analysis. This is the
third identified case of beta-p-alpha emission. We discuss the systematic of
beta-delayed particle emission decays, show that our observed decays fit
naturally into the existing pattern, and argue that the patterns are to a large
extent caused by odd-even effects.Comment: 6 pages, 5 figure
