A direct proof of Malus' theorem using the symplectic structure of the set of oriented straight lines [PDF]

open access: yes, 2014
We present a direct proof of Malus' theorem in geometrical Optics founded on the symplectic structure of the set of all oriented straight lines in an Euclidean affine space.

On Realism and Quantum Mechanics

open access: yes, 2007
A discussion of the quantum mechanical use of superposition or entangled states shows that descriptions containing only statements about state vectors and experiments outputs are the most suitable for Quantum Mechanics.

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

open access: yesInsect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Living by the lake: Plant food diversity in a prehistoric lake‐dwelling community in the Republic of North Macedonia

open access: yesArchaeometry, EarlyView.
Abstract This paper explores the relationship between wetland ecosystems and prehistoric lakeshore settlements within the Lake Ohrid basin (a biodiversity hotspot) by considering plant food systems at Ploča Mičov Grad, North Macedonia. The mid‐fifth millennium (c.4555–4373 to 4437–4241 cal BCE) waterlogged assemblage contained a diverse spectrum of ...

Differences in characteristics between naturalized threatened plants and other threatened plants

open access: yesConservation Biology, EarlyView.
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

Natural‐based antioxidants in cosmeceuticals: Extraction, bioavailability and skin ageing applications

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Natural antioxidants from plants, fruits, seeds and fungi combat ageing by neutralizing free radicals, boosting collagen and protecting against UV damage. Enhanced by green extraction and smart delivery systems, they offer powerful anti‐inflammatory and antimicrobial benefits.

Bonus–malus systems with different claim types and varying deductibles

open access: yesModern Stochastics: Theory and Applications, 2017
The paper deals with bonus–malus systems with different claim types and varying deductibles. The premium relativities are softened for the policyholders who are in the malus zone and these policyholders are subject to per claim deductibles depending on ...
