Named Entity Detection and Injection for Direct Speech Translation
In a sentence, certain words are critical for its semantic. Among them, named
entities (NEs) are notoriously challenging for neural models. Despite their
importance, their accurate handling has been neglected in speech-to-text (S2T)
translation research, and recent work has shown that S2T models perform poorly
for locations and notably person names, whose spelling is challenging unless
known in advance. In this work, we explore how to leverage dictionaries of NEs
known to likely appear in a given context to improve S2T model outputs. Our
experiments show that we can reliably detect NEs likely present in an utterance
starting from S2T encoder outputs. Indeed, we demonstrate that the current
detection quality is sufficient to improve NE accuracy in the translation with
a 31% reduction in person name errors.Comment: \c{opyright} 2022 IEEE. Personal use of this material is permitted.

Search for Neutral Higgs Bosons in Events with Multiple Bottom Quarks at the Tevatron
The combination of searches performed by the CDF and D0 collaborations at the
Fermilab Tevatron Collider for neutral Higgs bosons produced in association
with b quarks is reported. The data, corresponding to 2.6 fb-1 of integrated
luminosity at CDF and 5.2 fb-1 at D0, have been collected in final states
containing three or more b jets. Upper limits are set on the cross section
multiplied by the branching ratio varying between 44 pb and 0.7 pb in the Higgs
boson mass range 90 to 300 GeV, assuming production of a narrow scalar boson.
Significant enhancements to the production of Higgs bosons can be found in
theories beyond the standard model, for example in supersymmetry. The results
are interpreted as upper limits in the parameter space of the minimal
supersymmetric standard model in a benchmark scenario favoring this decay mode.Comment: 10 pages, 2 figure
Combination of the top-quark mass measurements from the Tevatron collider
The top quark is the heaviest known elementary particle, with a mass about 40
times larger than the mass of its isospin partner, the bottom quark. It decays
almost 100% of the time to a boson and a bottom quark. Using top-antitop
pairs at the Tevatron proton-antiproton collider, the CDF and {\dzero}
collaborations have measured the top quark's mass in different final states for
integrated luminosities of up to 5.8 fb. This paper reports on a
combination of these measurements that results in a more precise value of the
mass than any individual decay channel can provide. It describes the treatment
of the systematic uncertainties and their correlations. The mass value
determined is GeV or GeV, which has a precision of , making this the most precise determination of the top quark mass.Comment: 30 pages and 6 figures, published in Phys. Rev.
Clinical trial through the eyes of patients:Benefit or unjustified risk?
Introduction. Clinical trials (CTs) are the footing foundation of evidence-based medicine. In Russia many aspects of CT implementation remain unexplored; one of them is the attitude of Russian society. Aims. This study aims to determine the knowledge and perception of CTs by potential participants. Analysis of the perception of CTs through the eyes of patients: CTs - is it a benefit or an unjustified risk? Materials. The primary method of research was a questionnaire. A total of 488 anonymous, voluntary surveys of patients from hospitals in Tomsk were studied. Results. More than half of the respondents heard about CTs, while the primary source of information was the media. The participants adequately assess the importance of conducting CTs to develop medicine and medical care for society. The primary goal of CTs is to determine the effectiveness and safety of drugs, and respondents regard their engagement as an opportunity to contribute to the development of science. The primary motivating factor in participating in CTs is receiving treatment for an incurable disease and observing conditions by a qualified doctor. The central negative aspect is the possibility of causing a risk to own health. The questionnaire demonstrated the need and importance of all points of informed consent. Several questions concerned the public attitude to researchers. According to patients, medical researchers arouse trust and confidence in altruistic motives during the CTs. Conclusion. This study revealed a low interest of Russians in participating in CTs, except for personal benefit. The behavior of the doctors, the ability to convey reliable information to the patient to adequately assess benefits and possible risks play an important role in deciding on the involvement of patients in the CTs. The results of this work will allow us to adapt the process of organizing CTs to the needs of patients in the local context
