High‐Grade B‐Cell Lymphoma With 11q Aberration in Africa: A Differential Diagnosis in Cases With Features of Endemic Burkitt Lymphoma

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Fifty years ago, Zech et al. in this journal described for the first time the t(8;14) as a recurrent chromosomal aberration in Burkitt lymphoma (BL). Nevertheless, in regions where BL is not endemic, a subset of lymphomas with features of BL lacks the t(8;14)/IG::MYC and instead represents high‐grade B‐cell lymphoma with 11q aberration (HGBCL ...

Partial Identification of Population Average and Quantile Treatment Effects in Observational Data Under Sample Selection

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT This article partially identifies population treatment effects in observational data under both non‐random treatment assignment and sample selection. Bounds are provided for both average and quantile population treatment effects, combining assumptions for the selected and the non‐selected subsamples.

Exact Values and Bounds on Covering Schemes of Strength Two

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT In this work, we investigate covering schemes of strength 2 over finite abelian groups, establishing new lower and upper bounds and evaluating new exact values. A main result is a new general lower bound that improves the trivial one and achieves optimality for the binary case. We also develop a recursive relation based on subsets of the group

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

open access: yesInternational Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Structure and Propagation of Mesoscale Cyclonic Eddies in the Brazil–Malvinas Confluence

open access: yesInternational Journal of Climatology, EarlyView.
Between 1993 and 2022, 1386 cyclonic eddies were identified in the Brazil–Malvinas Confluence, one of the most energetic regions of the South Atlantic. While most eddies dissipated locally, a smaller number of individuals, more energetic, and longer lived propagated predominantly south‐westward and north‐eastward, driven by topographic constraints and ...

A talus rock glacier in Nantlle Valley, North Wales

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...
