Structure Functions are not Parton Probabilities [PDF]

open access: yes, 2001
We explain why contrary to common belief, the deep inelastic scattering structure functions are not related to parton probabilities in the target.Comment: 4 pages.

Traps, Tail States and Their Consequences on the Open‐circuit Voltage in Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
It is found that the light‐intensity dependent low‐temperature roll‐off of open‐circuit voltage in organic solar cells is explained by the intrinsic disorder in these devices, which can be either described by the full Gaussian density of states or approximated by a two‐level system, which allows for a more intuitive interpretation.

Tuning Exciton Dynamics and Energy Transfer in Ternary Organic Solar Cells Using Pyridine‐Flanked DPP Acceptors

open access: yesAdvanced Energy Materials, EarlyView.
Three novel non‐fullerene acceptors with a DPP–pyridine‐based structure have been studied, each incorporating different π‐bridging units. LM‐Se exhibited the highest efficiency among the NFAs, and its incorporation into a ternary blend with D18 and Y6 (PCE = 17.53%) significantly enhanced performance due to improved charge dynamics and favorable film ...

Physics at the Light-Front [PDF]

open access: yes, 2001
The light-front representation of quantum chromodynamics provides a frame-independent, quantum-mechanical representation of hadrons at the amplitude level, capable of encoding their multi-quark, hidden-color and gluon momentum, helicity, and flavor ...

Ontogeny of the malleus in Mesocricetus auratus (Mammalia, Rodentia): Systematic and functional implications for the muroid middle ear

open access: yesThe Anatomical Record, EarlyView.
Abstract The three mammalian auditory ossicles enhance sound transmission from the tympanic membrane to the inner ear. The anterior anchoring of the malleus is one of the key characters for functional classification of the auditory ossicles. Previous studies revealed a medial outgrowth of the mallear anterior process, the processus internus ...
