An investigation on the skewness patterns and fractal nature of research productivity distributions at field and discipline level

open access: yes, 2017
The paper provides an empirical examination of how research productivity distributions differ across scientific fields and disciplines. Productivity is measured using the FSS indicator, which embeds both quantity and impact of output.

Generalized graphical mixed models connect ecological theory with widely used statistical models

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 4, Page 1290-1302, April 2026.
Abstract Ecological dynamics are often analysed across multiple sites, times, and variables. Ecologists typically represent interactions across space, time, and variables using generalized linear mixed models (GLMMs), generalized additive models (GAM), and structural equation models (SEM).

Should Research Universities be led by top researchers? Part 1: Are they? [PDF]

open access: yes
If the best universities in the world – who have the widest choice of candidates – systematically appoint top researchers as their vice chancellors and presidents, is this one form of evidence that, on average, better researchers make better leaders ...

Piecework versus merit pay: a Mean Fi eld Game approach to academic behavior [PDF]

open access: yes
This paper applies the Mean Fi eld Game approach pioneered by Lasry and Lions (2007) to the analysis of the researchers' academic productivity. It provides a theoretical motivation for the stability of the universaly observed Lotka's law. It shows that a

Numerical Parameter‐Space Studies of Various Types of Thundercloud Gamma‐Ray Emissions

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Until recently, mainly two types of hard radiation were observed in thunderstorms: intensive, short‐lived terrestrial gamma‐ray flashes (TGFs) and weak, long‐lasting gamma‐ray glows (GRGs). The Airborne Lightning Observatory for Fly's Eye GLM Simulator and TGFs (ALOFT, GLM: Geostationary Lightning Mapper) flight campaign revealed additional ...

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, Volume 600, Issue 6, Page 808-836, March 2026.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
