Body Size Regulates Niche Overlap Asymmetry in the Subtropical Andes Rain Shadow: Isotopic Paleoecology of Oligocene South American Ungulates

open access: yesIntegrative Zoology, EarlyView.
This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Examining associations between foundational and complex mathematics skills in people with Down syndrome and typically developing children

open access: yesBritish Journal of Developmental Psychology, EarlyView.
Abstract Acquiring mathematical competence is essential to independent living. In this study, we investigated the mathematics profile in young people with Down syndrome (DS), and the relations between foundational and more complex mathematics skills.

The $(2,3)$-generation of the finite unitary groups

open access: yes, 2019
In this paper we prove that the unitary groups $SU_n(q^2)$ are $(2,3)$-generated for any prime power $q$ and any integer $n\geq 8$. By previous results this implies that, if $n\geq 3$, the groups $SU_n(q^2)$ and $PSU_n(q^2)$ are $(2,3)$-generated, except

Highly ionized Fe K emission lines from the LINER galaxy M 81 [PDF]

open access: yes, 2004
We present spectral and timing results from a long (130 ks) XMM-NEWTON EPIC observation of the nucleus of the Seyfert/LINER galaxy M 81. During the observation the X-ray flux varied by 20%, but there was no significant change in spectral shape.

Immune‐related adverse events in the treatment of Hodgkin lymphoma with immune checkpoint inhibitors

open access: yesBritish Journal of Haematology, EarlyView.
Summary Immune checkpoint inhibitors (ICIs) have shown to be effective in the treatment of Hodgkin lymphoma (HL). ICI treatment is associated with the occurrence of a series of immune‐related adverse events (irAEs). We conducted an ambispective observational study on 96 patients with relapsed/refractory HL treated with ICIs to determine the incidence ...
