Misrepresentation of group contributions undermines conditional cooperation in a human decision making experiment [PDF]

open access: yesScientific Reports, 2022
Cooperative behaviour can evolve through conditional strategies that direct cooperation towards interaction partners who have themselves been cooperative in the past.

Generic Context-Aware Group Contributions [PDF]

open access: yesIEEE/ACM Transactions on Computational Biology and Bioinformatics, 2022
Many properties of molecules vary systematically with changes in the structural formula and can thus be estimated from regression models defined on small structural building blocks, usually functional groups. Typically, such approaches are limited to a particular class of compounds and requires hand-curated lists of chemically plausible groups.

Contributions of group work programs in achieving social rehabilitation for juvenile delinquents. [PDF]

open access: yesمجلة مستقبل العلوم الإجتماعیة, 2020
The phenomenon of juvenile delinquency constitutes a serious problem within societies that all professions and scientific disciplines seek to deal with, including the profession of social work. The method of working with groups uses many programs to deal

Contributions to a revision of the Hylaeus brevicornis group (Hymenoptera, Anthophila, Colletidae) [PDF]

open access: yesContributions to Entomology, 2022
The Hylaeus brevicornis group of the subgenus Dentigera is defined and revised. A total of 22 species are included in the group, their circumscription and identification using morphological characters is described and discussed, and their distribution is

Contribution-Based Grouping under Noise [PDF]

open access: yesGames, 2017
Many real-world mechanisms are “noisy” or “fuzzy”, that is the institutions in place to implement them operate with non-negligible degrees of imprecision and error. This observation raises the more general question of whether mechanisms that work in theory are also robust to more realistic assumptions such as noise.

Identifying group contributions in NBA lineups with spectral analysis

open access: yesJournal of Sports Analytics, 2020
We address the question of how to quantify the contributions of groups of players to team success. Our approach is based on spectral analysis, a technique from algebraic signal processing, which has several appealing features.

Vacuum Effective Actions and Mass-Dependent Renormalization in Curved Space

open access: yesUniverse, 2019
We review past and present results on the non-local form-factors of the effective action of semiclassical gravity in two and four dimensions computed by means of a covariant expansion of the heat kernel up to the second order in the curvatures.
