Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer
Boreas, EarlyView.Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Transient rheology of the Sumatran mantle wedge revealed by a decade of great earthquakes
Nature Communications, 2018 The rheology of the upper mantle is key to understanding how plate tectonics may evolve. Here, using GPS and tide-gauge measurements along the Sumatran subduction zone, the authors’ show that a bi-viscous rheology model is needed to explain the stress ...

Petrological features of Subei Basin (Eastern China) lithospheric mantle and their relationships with H2O contents in NAMs [PDF]
, 2010 The Subei basin is located east of the Tanlu fault, a major discontinuity which separates the Archean North China Craton from the Proterozoic Yangtze Craton.

Journal of Cutaneous Pathology, EarlyView.ABSTRACT Aberrant expression of T‐cell markers in B‐cell lymphomas is rare and can pose diagnostic challenges. We report a case of a 65‐year‐old man presenting with newly developed scalp nodules. Histopathology revealed nodular lymphoid infiltrates composed of large centrocytes and centroblasts.

Contrasting Food Web Dynamics Across Oceanographic Boundaries in Subarctic Pelagic Ecosystems
Fisheries Oceanography, EarlyView.ABSTRACT Understanding the structure of pelagic food webs across multiple trophic levels is critical for elucidating species interactions, energy flow, and anthropogenic impacts on production. This study presents a comprehensive analysis of the eastern North Pacific pelagic food webs, focusing on the Gulf of Alaska (GoA) during late winter of 2019.

PGM in chromitites of Kraka massifs (the Southern Urals): diversity and origin
GeoresursyThe paper provides results of study of platinum group minerals (PGMs) from 18 ore occurrences and deposits of the Kraka massifs, most of these located in ultramafic rocks of the upper mantle section (15), and several occurrences in a crust-mantle ...

Histopathology, EarlyView.This is a retrospective review of intestinal tract biopsies from patients treated with various cellular immunotherapies (BCMA and CD19‐directed CAR T, teclistamab and rituximab therapies). We found distinct but overlapping histologic patterns across treatment groups, with lamina propria plasma cell depletion, crypt apoptotic bodies and active ...

Evolution of the continental upper mantle : numerical modelling of thermo-chemical convection including partial melting [PDF]
, 1999 This thesis elaborates on the evolution of the continental upper mantle based on numerical modelling results. The descriptive and explanatory basis is formed by a numerical thermo-chemical convection model.
