Narrow-domain Short Texts Clustering Algorithm

In this paper, we describe the algorithm of narrow-domain short texts clustering, which is based on terms’ selection and modification of k-means algorithm. Our approach was tested on collections: CICling–2002 and SEPLIN-CICling. Results of tests and conclusions are presented

Inversionless gain in a three-level system driven by a strong field and collisions

Inversionless gain in a three-level system driven by a strong external field and by collisions with a buffer gas is investigated. The mechanism of populating of the upper laser level contributed by the collision transfer as well as by relaxation caused by a buffer gas is discussed in detail. Explicit formulae for analysis of optimal conditions are derived. The mechanism developed here for the incoherent pump could be generalized to other systems.Comment: RevTeX, 9 pages, 4 eps figure

Public Health Training Needs Assessment in Bulgaria: A Necessary and Continuous Process

The development of public health education has its solid grounds both in the modern trends of the European health policy and in the national context. It is acknowledged that public health training should adequately meet the demand for professionals to involve in practice and research. The content of the training programmes should correspond to the needs for specific public health knowledge, skills and competencies. This study is aimed at assessing the need for public health professionals in Bulgaria and exploring the specific training needs in terms of necessary knowledge and skills. The methods involved refer to opinion assessment of three target groups: experts, employers, and students at the Master of Public Health programme of Varna University of Medicine by personal (face-to-face) interviews orpostar questionnaires. The results show that the need for public health education is widely recognized and it meets the stakeholders' interest in possibilities for public health workforce training and qualification

Inversionless light amplification and optical switching controlled by state-dependent alignment of molecules

We propose a method to achieve amplification without population inversion by anisotropic molecules whose orientation by an external electric field is state-dependent. It is based on decoupling of the lower-state molecules from the resonant light while the excited ones remain emitting. The suitable class of molecules is discussed, the equation for the gain factor is derived, and the magnitude of the inversionless amplification is estimated for the typical experimental conditions. Such switching of the sample from absorbing to amplifying via transparent state is shown to be possible both with the aid of dc and ac control electric fields.Comment: AMS-LaTeX v1.2, 4 pages with 4 figure
