Paternal p,p′-DDE exposure and pre-pubertal high-fat diet increases the susceptibility to fertility impairment and sperm Igf2 DMR2 hypo-methylation in male offspring

open access: yesEcotoxicology and Environmental Safety
The hypothesis of paternal origins of health and disease (POHaD) indicates that paternal exposure to adverse environment could alter the epigenetic modification in germ line, increasing the disease susceptibility in offspring or even in subsequent ...

Time-Changed Poisson Processes

open access: yes, 2011
We consider time-changed Poisson processes, and derive the governing difference-differential equations (DDE) these processes. In particular, we consider the time-changed Poisson processes where the the time-change is inverse Gaussian, or its hitting time

Methods Based on Polynomial Chaos for Quadratic Delay Differential Equations With Random Parameters

open access: yesPAMM, Volume 26, Issue 1, March 2026.
ABSTRACT We consider systems of delay differential equations (DDEs), including a single delay and a quadratic right‐hand side. In a system, parameters are replaced by random variables to perform an uncertainty quantification. Thus the solution of the DDEs becomes a random process, which can be represented by a series of the generalised polynomial chaos.

Wintering Area DDE Source to Migratory White-Faced Ibis Revealed by Satellite Telemetry and Prey Sampling [PDF]

open access: yes, 2010
Locations of contaminant exposure for nesting migratory species are difficult to fully understand because of possible additional sources encountered during migration or on the wintering grounds.

Developmental trajectories of visual temporal integration and segregation in children with and without developmental dyslexia

open access: yesBritish Journal of Developmental Psychology, Volume 44, Issue 1, Page 146-165, March 2026.
Abstract In the present study, 43 Italian school‐age children (age range = 7–14 years, 16 females) with (N = 19) and without DD (N = 24) were presented with pairs of visual displays separated by varying interstimulus intervals and performed either a temporal integration or segregation task despite an identical visual input.

Genetic Encoding of a Trifunctional Photo‐Cross‐Linker with a Cleavable Alkyl Ester Moiety

open access: yesChemBioChem, Volume 27, Issue 3, 12 February 2026.
A novel noncanonical amino acid, DiZAAsu, possessing photo‐cross‐linking, biotinylation, and alkaline‐cleavable functionalities, is genetically encoded by an engineered pyrrolyl‐tRNA synthetase mutant. The alkyl ester moiety expands the design space of cleavable photo‐cross‐linkable amino acids.

A Recipe for State Dependent Distributed Delay Differential Equations

open access: yes, 2018
We use the McKendrick equation with variable ageing rate and randomly distributed maturation time to derive a state dependent distributed delay differential equation.

SSZ‐13‐Zeolith mit Isolierten Co2+‐Zentren als ein Effizientes und Beständiges Katalysatorsystem für die Nichtoxidative Ethandehydrierung

open access: yesAngewandte Chemie, Volume 138, Issue 7, 9 February 2026.
Für die nichtoxidative Ethandehydrierung zu Ethen wurden Katalysatoren mit isolierten Co2+‐Spezies in den 6MR‐ (Co2+‐Z2) und 8MR‐Fenstern ([Co(OH)]+‐Z) eines SSZ‐13‐Zeolithen hergestellt. Die Co2+‐Z2‐Spezies zeigten im Vergleich zu den [Co(OH)]+‐Spezies eine unerwartet hohe Ethenbildungsgeschwindikeit.

SSZ‐13 Zeolite with Isolated Co2+ Sites as an Efficient and Durable Catalyst System for Non‐Oxidative Ethane Dehydrogenation

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 7, 9 February 2026.
Catalysts with the isolated Co2+ species in the 6MR (Co2+─Z2) and 8MR ([Co(OH)]+─Z) windows of the SSZ‐13 zeolite were synthesized for non‐oxidative ethane dehydrogenation to ethene. The Co2+─Z2 species demonstrate an unexpectedly high rate of ethene formation in comparison with the ([Co(OH)]+─Z species.
