Pains and Gains of Peer Reviewing in Software Engineering

A young software engineering researcher is invited to be an associate editor (AE) of a major journal in our field. The researcher is very excited. By this point, she has amassed a nice career track-record. She has also been recognized via a number of invitations to serve on our conferences' program committees. But this somehow feels different and more important: there are multiple conferences each year, and all of them have PCs staffed with dozens of members (not uncommonly over 100 in recent years), while there are comparatively fewer journals and, at any point in time, the sizes of their editorial boards are a fraction of a typical conference PC. This is a major additional sign of recognition of the young researcher's expertise and stature in the community. So, the researcher quickly and enthusiastically accepts the invitation.

Abstract Tropical Linear Programming

In this paper we develop a combinatorial abstraction of tropical linear programming. This generalizes the search for a feasible point of a system of min-plus-inequalities. We obtain an algorithm based on an axiomatic approach to this generalization. It builds on the introduction of signed tropical matroids based on the polyhedral properties of triangulations of the product of two simplices and the combinatorics of the associated set of bipartite graphs with an additional sign information. Finally, we establish an upper bound for our feasibility algorithm applied to a system of min-plus-inequalities in terms of the secondary fan of a product of two simplices. The appropriate complexity measure is a shortest integer vector in a cone of the secondary fan associated to the system.

Accounting technique of the three-component indicator of the financial situation type in the analysis of the food industry enterprises capital structure

Among the existing characteristics of a financial condition of the enterprise a specific place is held by a three-component financial situation indicator (degree of a covering of stocks by own sources) which considers some arti-cles of balance which are seldom used at usual assessment of a financial state. Therefore for establishment of im-portance of this indicator it is offered to pass from a discrete three-component indicator to a continuous indicator – coefficient of sufficiency of a stocks covering with own sources of means and to carry out the correlation analysis of communication of the last with results of the scoring analysis of the same enterprises. To consider influence of a three-component indicator on the general results of assessment of a financial state, the technique of accounting of its influence on the example of indicators of structure of the capital is developed, i.e. the set of the considered finan-cial coefficients due to introduction of additional sign – the mentioned coefficient of sufficiency of a stocks cover-ing is expanded own sources. Comparison of estimates of the generalized indicator of structure of the capital before expansion at the expense of sufficiency coefficient in an indistinct set form allows define the recommended scopes of the offered approach.

Multimodal Imaging of Vitreoretinal Lymphoma

Purpose: To assess the characteristics and prevalence of fundus abnormalities in vitreoretinal lymphoma (VRL) using multimodal imaging. Methods: We retrospectively reviewed chart and imaging studies of patients diagnosed with VRL. Results: All 10 VRL patients (14 eyes) included in the study showed vitreitis, hyperreflective lesions on near-infrared reflectance imaging, and hypoautofluorescent lesions on fundus autofluorescence. Other findings included hypofluorescent lesions on fluorescein angiography (79%), hypocyanescent lesions on indocyanine green angiography (77%), small retinal pigment epithelium detachments (PEDs) (71%) and large PEDs (36%) on optical coherence tomography (OCT). Outer retinal layer nodularity was identified on OCT in 93% of cases. Small PEDs corresponded to hyperreflective, hyperautofluorescent, hypofluorescent, hypocyanescent lesions. Conclusion: Multiple signs were present on multimodal imaging in VRL eyes. Lymphomatous infiltration created focal PEDs showing abnormal imaging signals. Outer retinal layer nodularity could represent an additional sign of infiltration. Multimodal imaging may guide physicians in the early diagnosis of VRL.
