The previous edition focused in particular on these issues:

The objective of Nonlinear Analysis: Hybrid Systems is to combine knowledge in the areas of Control theory, Nonlinear system, Lyapunov function, Control theory and Stability (probability). While Control theory is the focus of the journal, it also provided insights into the studies of Function (mathematics) and State (functional analysis). Issues in Nonlinear system were discussed, taking into consideration concepts from other disciplines like Power (physics), Class (set theory), Growth rate and Robustness (computer science).

The concepts on Lyapunov function presented in Nonlinear Analysis: Hybrid Systems can also apply to other research fields, including Finite time, Exponential stability, Graph theory, Applied mathematics and Piecewise. Topics in Control theory were tackled in line with various other fields like Stability (learning theory), Control (management), Actuator, Asynchronous communication and Trajectory. Markov jump and Work (thermodynamics) are some topics wherein Stability (probability) research discussed in Nonlinear Analysis: Hybrid Systems have an impact.

The most cited articles from the last journal are:

• Feedback control based on discrete-time state observations on synchronization of stochastic impulsive coupled systems (15 citations)
• Razumikhin-type theorem for pth exponential stability of impulsive stochastic functional differential equations based on vector Lyapunov function (14 citations)
• Synchronized stationary distribution for stochastic multi-links systems with Markov jump (7 citations)

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 7.14% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 25.00% were posted by at least one author from the top 10 institutions publishing in the journal. Another 10.58% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 17.31% of all publications and 47.12% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

• Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
• Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
• Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
• Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
• Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.
