Electronic Report Generation Web Service evaluated within a Telemedicine System
This work presents a generic tool based on a client-server architecture that generates electronic reports helping the evaluation process of any information system. For the specific evaluation of telemedicine systems the defined reports cover four dimensions: auditory of the system; evolution of clinical protocols; results from the questionnaires for user acceptance and quality of life; and surveillance of clinical variables. The use of a Web Service approach allows multiplatform use of the developed electronic report service and the modularity followed in the implementation enables easy system evolution and scalability
Pragmatic Radiology Report Generation
When pneumonia is not found on a chest X-ray, should the report describe this
negative observation or omit it? We argue that this question cannot be answered
from the X-ray alone and requires a pragmatic perspective, which captures the
communicative goal that radiology reports serve between radiologists and
patients. However, the standard image-to-text formulation for radiology report
generation fails to incorporate such pragmatic intents. Following this
pragmatic perspective, we demonstrate that the indication, which describes why
a patient comes for an X-ray, drives the mentions of negative observations and
introduce indications as additional input to report generation. With respect to
the output, we develop a framework to identify uninferable information from the
image as a source of model hallucinations, and limit them by cleaning
groundtruth reports. Finally, we use indications and cleaned groundtruth
reports to develop pragmatic models, and show that they outperform existing
methods not only in new pragmatics-inspired metrics (+4.3 Negative F1) but also
in standard metrics (+6.3 Positive F1 and +11.0 BLEU-2).Comment: 18 pages, 1 figure, 18 tables. Code at

Continuously wavelength-tunable high harmonic generation via soliton dynamics
We report generation of high harmonics in a gas-jet pumped by pulses
self-compressed in a He-filled hollow-core photonic crystal fiber through the
soliton effect. The gas-jet is placed directly at the fiber output. As the
energy increases the ionization-induced soliton blue-shift is transferred to
the high harmonics, leading to a emission bands that are continuously tunable
from 17 to 45 eV
An Eprints Apache Log Filter for Non-Redundant Document Downloads by Browser Agents
Web log files record a vast amount of information and much of it just gets in the way of meaningful observational studies on usage. It is therefore necessary to filter out the junk in a deliberate way before making statements on how the web is being used. This report describes the methods and scripts used to accomplish apache web log filtering and report generation. It is open to scrutiny and freely available for others to use
Squeezing at 946nm with periodically-poled KTiOPO_4
We report generation of squeezed vacuum in sideband modes of continuous-wave
light at 946 nm using a periodically poled KTiOPO_4 crystal in an optical
parametric oscillator. At the pump power of 250 mW, we observe the squeezing
level of -5.6+/-0.1 dB and the anti-squeezing level of +12.7+/-0.1 dB. The pump
power dependence of the observed squeezing/anti-squeezing levels agrees with
the theoretically calculated values when the phase fluctuation of locking is
taken into account.Comment: 3 pages, 3 figures, submitted to Optics Letter
Generation of a squeezed vacuum resonant on Rubidium D_1 line with periodically-poled KTiOPO_4
We report generation of a continuous-wave squeezed vacuum resonant on the Rb
D_1 line (795 nm) using periodically poled KTiOPO_4 (PPKTP) crystals. With a
frequency doubler and an optical parametric oscillator based on PPKTP crystals,
we observed a squeezing level of -2.75 +- 0.14 dB and an anti-squeezing level
of +7.00 +- 0.13 dB. This system could be utilized for demonstrating storage
and retrieval of the squeezed vacuum, which is important for the ultra-precise
measurement of atomic spins as well as quantum information processing.Comment: 4 pages, 4 figure
